The following detailed description is made with reference to the accompanying drawings.

Referring to fig. 1 to 3 and fig. 5, wherein fig. 1 is a front view of the oral cleaning product disclosed in this embodiment, fig. 2 is an exploded view of the oral cleaning product disclosed in this embodiment, fig. 3 is a front view of a bottle body disclosed in this embodiment, and fig. 5 is a sectional view of the bottle body disclosed in this embodiment. The oral cleaning product in this embodiment includes a body 10, a cap assembly 20, and a mouthwash 30.

The bottle body 10 includes a main body 11, an arc transition portion 14, a neck 12 and a mouth portion 13, wherein the main body 11, the arc transition portion 14, the neck 12 and the mouth portion 13 are sequentially connected along a direction from the bottom to the top of the bottle body 10. The main body 11 and the arc transition portion 14 enclose to form an accommodating cavity 1101, a water outlet channel 121 penetrates through the neck portion 12 in the height direction, a water outlet hole 131 penetrates through the bottle mouth portion 13 in the height direction, one end of the water outlet channel 121 is communicated with the accommodating cavity 1101, the other end of the water outlet channel is communicated with the water outlet hole 131, the mouthwash 30 is accommodated in the accommodating cavity 1101, and when the bottle body 10 is vertically placed in a horizontal plane (as in the state of fig. 1 to 3), the liquid level 31 of the mouthwash 30 is lower than the neck portion 12. The cap assembly 20 is detachably mounted to the neck 12 to seal the outlet hole 131. When actual packing mouthwash, the chamber 1101 that holds of body 10 is added to can be followed apopore 131 to mouthwash 30, then seal up apopore 131 through bottle lid subassembly 20 can.

The height D of the combined body portion 11 and the arc-shaped transition portion 14 is 1/3-1, and the ratio of the height D of the neck portion 12 to the height D of the combined body portion 11 and the arc-shaped transition portion 14 is 1/3-1. Illustratively, the ratio of the height D of the neck portion 12 to the height D of the body portion 11 is 1/3, 2/5, 1/2, 0.7, 4/5, or 1, and so forth. That is, the ratio of the length of the outlet channel 121 disposed on the neck 12 to the length d of the main body 11 is 1/3 to 1, and compared to the existing mouthwash packaging bottle without the neck 12 on the market, the bottle body 10 of the oral cleaning product of the present invention has a longer outlet channel 121, so that when the user pours the mouthwash 30, the longer outlet channel 121 can pour the mouthwash 30 at a slower speed at the same inclination angle. Meanwhile, the water outlet channel 121 with the proper length can give a user a certain reaction time when pouring the mouthwash 30 to control the amount of the poured mouthwash, and the water outlet channel 121 with the proper length also provides a visual observation window for the user to see and control the pouring speed of the mouthwash.

When the user needs to use the mouthwash 30, the bottle cap assembly 20 only needs to be taken down from the water outlet hole 131, and the bottle body 10 is inclined, so that the mouthwash 30 in the accommodating cavity 1101 flows along the water outlet channel 121, and flows out from the water outlet hole 131 and is poured into other containers for use. However, if the ratio of the height D of the neck 12 to the height D of the body 11 is less than 1/3, the discharge rate of the mouthwash 30 is relatively high and the discharge amount is not easily controlled. If the ratio of the height D of the neck 12 to the height D of the body 11 is greater than 1, the outlet channel 121 is relatively long, and the mouthwash 30 can flow out of the outlet channel 121 in a long time, and can be poured out of the mouthwash 30 in the bottle body 10 in a large inclined angle, which is inconvenient for users to use. By setting the height D of the neck 12 to 1/3-1 of the height D of the main body 11, the mouthwash 30 can be poured out by a comfortable gesture, the pouring amount of the mouthwash 30 is easier to control, and the container for holding the mouthwash 30 is particularly suitable for a container with a relatively small capacity.

In some embodiments, the height D of the neck 12 is 60mm to 80mm, such as 60mm, 65mm, 70mm, 75mm and 80mm, and correspondingly, the length of the water outlet channel 121 is in the range of 60mm to 80mm, which is more suitable for the user to control the pouring speed of the mouthwash 30.

In practical design, the main body 11, the arc-shaped transition portion 14, the neck 12 and the mouth portion 13 of the present embodiment are connected in sequence along the direction from the bottom to the top of the bottle body 10, the boundary line between the main body 11 and the arc-shaped transition portion 14 is shown as a straight line P1 in fig. 5, the boundary line between the neck 12 and the arc-shaped transition portion 14 is shown as a straight line P2 in fig. 5, and the boundary line between the neck 12 and the mouth portion 13 is shown as a straight line P3 in fig. 5, wherein the main body 11, the arc-shaped transition portion 14, the neck 12 and the mouth portion 13 may be arranged in a cylindrical shape, or in a prismatic shape or in another special-shaped cylindrical. Fig. 1 to 3 in the present embodiment show a case where the main body portion 11, the arc-shaped transition portion 14, the neck portion 12, and the finish portion 13 are arranged cylindrically. That is, the cross-sectional areas of the main body portion 11, the neck portion 12, and the finish portion 13 are all circular surfaces, and it can be understood that the cross-sectional areas of the main body portion 11, the arc-shaped transition portion 14, the neck portion 12, and the finish portion 13 refer to a cross-section obtained by cutting the body 10 in a direction perpendicular to the axis of the body 10.

Specifically, the bottle mouth portion 13 in this embodiment is a region covered and buckled by the bottle cap assembly 20, the arc-shaped transition portion 14 includes a first end 143 and a second end 144, an outer diameter of the arc-shaped transition portion 14 gradually decreases from the first end 143 to the second end 144, an outer diameter of the second end 144 is 0.7 of the outer diameter of the first end, the first end 143 is abutted with the main body portion 11, and the first end 143 is located at a position where an inner diameter of the accommodating cavity 1101 will start to continuously decrease. That is, the boundary P1 between main body portion 11 and curved transition portion 14 is located at the position where the inner diameter of receiving cavity 1101 will start to become smaller continuously, the boundary P2 between curved transition portion 14 and neck portion 12 is located at the position where the outer diameter of curved transition portion 14 becomes smaller than 0.7 of the outer diameter of main body portion 11, and the boundary P3 between neck portion 12 and finish portion 13 is located at the bottom end of the region covered by bottle cap assembly 20.

It should be noted that, the outer diameter of the arc-shaped transition portion 14 gradually decreases from the first end 143 to the second end 144, which means that the first end 143 to the second end 144 as a whole presents a gradually decreasing trend, in some embodiments, the outer peripheral wall of the arc-shaped transition portion 14 may be provided with patterns or a small section presenting a slightly protruding structure, and such gradual decrease without local influence on the whole trend should also be within the protection scope of the present invention, i.e. should be in the scope of "gradually decreasing".

Illustratively, the outer diameter R1 of the body portion 11 is 55mm to 60mm, such as 55mm, 56mm, 57mm, 58mm, 59mm or 60 mm. By setting the outer diameter R1 of the main body 11 to 55mm to 60mm, which is adapted to the inner diameter of the C-shaped or circular cavity surrounded by the thumb and the four fingers of most people, the main body 11 can be held by the hand of the user, which is more ergonomic. The outer diameter R2 of the neck 12 is 25mm to 35mm, for example 25mm, 27mm, 29mm, 31mm, 33mm or 35 mm. If the outer diameter R2 of neck 12 is less than 25mm, neck 12 is thin and easily breaks; if the outer diameter R2 of the neck 12 is larger than 35mm, the neck 12 is relatively thick, which tends to increase the weight of the body 10. That is, by setting the outer diameter R2 of the neck portion 12 to 25mm to 35mm, the dimensions of the neck portion 12 and the body portion 11 can be arranged appropriately, and the structural strength of the entire body 10 can be improved. The outer diameter of the bottle mouth portion 13 is 25mm to 30mm, for example, 25mm, 27mm, or 30 mm. Setting the outside diameter dimension of finish portion 13 to 25mm to 30mm enables a good transition with neck 12 and facilitates alignment of finish portion 13 with other containers for pouring of mouthwash 30.

Further, the arc-shaped transition portion 14 in the present embodiment includes a convex arc section 141 and a concave arc section 142 connected to each other, and the convex arc section 141 and the concave arc section 142 are sequentially arranged in the direction from the main body portion 11 to the neck portion 12. It is understood that the convex arc section 141 refers to an arc section protruding toward the outside of the body 10, and the concave arc section 142 refers to an arc section protruding toward the inside of the body 10. As shown in fig. 4, fig. 4 is an enlarged view of fig. 3 at the arcuate transition 14. As can be seen from fig. 4, the boundary between the convex arc segment 141 and the concave arc segment 142 in the present embodiment is shown by a curve T. When the oral cavity cleaning product is used, in some holding modes, when a user holds the arc-shaped transition part 14, the convex arc section 141 is positioned in the hand of the user, and the tiger mouth part of the hand of the user can be positioned in the concave arc section 142, so that the oral cavity cleaning product is more suitable for the user to hold the bottle body 10.

Meanwhile, by arranging the arc-shaped transition portion 14 as the convex arc section 141 and the concave arc section 142 sequentially arranged in the direction from the main body portion 11 to the neck portion 12, the inner side wall surface of the accommodating chamber 1101 is relatively smooth, and when the mouthwash 30 is poured, the mouthwash 30 can smoothly flow into the water outlet channel 121 along the inner wall surface of the arc-shaped transition portion 14. When the bottle body 10 is vertically placed, the liquid level of the mouthwash 30 is lower than the neck 12, that is, the filling amount of the mouthwash 30 is exquisite, the liquid level of the mouthwash 30 is lower than the neck 12, a large hollow section is formed between the liquid level and the bottleneck 13, when the mouthwash 30 is poured, a long stroke is needed to reach the bottleneck 13 from the containing cavity 1101, so that a user has enough reaction time to control the pouring amount of the mouthwash 30, and the hollow section also provides an operation space for the user to adjust the pouring amount of the mouthwash 30, therefore, the oral cleaning product controls the liquid level of the mouthwash 30 below the arc-shaped transition part 14, and is more favorable for the stable and controllable pouring of the mouthwash 30.

Optionally, the convex arc segment 141 corresponds to a central angle of 25 ° to 40 °, such as 25 °, 28 °, 30 °, 33 °, 35 °, 38 °, or 40 °, and the concave arc segment 142 corresponds to a central angle of 10 ° to 20 °, such as 10 °, 12 °, 14 °, 16 °, 18 °, and 20 °. The central angles corresponding to the convex arc section 141 and the concave arc section 142 satisfy the degrees, and when the user holds the arc transition part 14 by hand, the palm of the hand can be well attached to the arc transition part 14, so that the use is more convenient and comfortable.

Referring to fig. 1 to 4, one end (bottom end of the bottle body 10) of the main body 11 away from the neck 12 is provided with a fillet 112, the fillet 112 can reduce the occurrence of a sharp corner, and can reduce the risk of deformation of the bottle body 10, and in the actual production process, the bottle body 10 is usually formed by mold opening processing, and the fillet 112 can reduce the difficulty in mold stripping of the bottle body 10, and reduce the processing and production cost of the bottle body 10.

Optionally, the bottom end surface of the main body 11 is provided with a recess 113, the recess 113 is recessed toward the inside close to the bottle body 10, and the recess 113 can keep the bottle body 10 standing up for a long time, can reasonably reduce the risk of scratching the bottom of the bottle body 10, and can give the bottle body 10 compressive strength such as gas pressure resistance and fluid pressure impact resistance to prevent the bottom of the bottle body 10 from cracking.

Further, the volume of the accommodating chamber 1101 in the present embodiment is 300ml to 350ml, such as 300ml, 310ml, 320ml, 330ml, 340ml or 350 ml. The volume ratio of the water outlet channel 121 to the accommodating cavity 1101 is 18/100 to 22/100, such as 18/100, 19/100, 20/200, 21/200 and 22/200. Through making holding chamber 1101 and outlet channel 121 satisfy foretell volume relation, can make the volume of the mouthwash 30 of whole oral cavity cleaning product take up more moderate, convenience of customers holds body 10 and uses, also convenience of customers goes out to carry. Meanwhile, in the process of pouring the mouthwash 30 by the user, the user usually holds the bottle body 10 with one hand to pour the mouthwash, if the volume of the containing cavity 1101 is larger, the amount of the mouthwash 30 during the first use is also more, the holding force required to be applied by the user needs to be larger, the mouthwash is not convenient for the user to use, that is, the volume of the containing cavity 1101 is set to be 300ml to 350ml in the embodiment, and the mouthwash 30 is more suitable for the user to pour the mouthwash 30.

Referring to fig. 7 to 10, fig. 7 is an enlarged view of an N region in fig. 5, fig. 8 is an enlarged view of a P region in fig. 5, fig. 9 is an enlarged view of an I region in fig. 8, and fig. 10 is an enlarged view of an M region in fig. 2. The friction buffer section 123 for increasing the friction between the hand of the user and the neck 12 is arranged on the periphery of the neck 12, the friction buffer section 123 is connected with the main body 11 through the arc-shaped transition part 14, and the friction between the hand and the neck 12 can be increased through the action of the friction buffer section 123, so that the user can conveniently hold the bottle body 10.

Alternatively, the friction buffer section 123 in the present embodiment may be an outward convex section provided on the outer periphery of the neck portion 12, and may also be an embossment or the like provided on the outer periphery of the neck portion 12. Fig. 7 in the present embodiment shows a case where the friction cushioning segment 123 is provided as an outward protrusion. Through setting up outer convex part on the lateral wall at neck 12, form interior concave part between this outer convex part and the main part 11, when user's hand held main part 11 and neck 12 transition position department, when hand tiger's mouth position was located interior concave part, outer convex part can play certain friction hindrance effect to user's hand, and the user of being convenient for grips body 10. When the user hand held the evagination department of neck 12, user's finger encircles the evagination and holds neck 12, and the setting of evagination can be held the cavity looks adaptation that forms with user's finger, more accords with human engineering design, further promotes the good experience of user and feels.

Further, the inner side wall surface of the outlet channel 121 is provided with a ring of recessed portions 122, the recessed portions 122 are recessed toward the outer side wall surface of the neck portion 12, the recessed portions 122 are located between the accommodating cavity 1101 and the mouth portion 13, and the recessed portions 122 are used for temporarily storing the mouthwash 30 and reducing the flow rate of the mouthwash 30. When the mouthwash 30 flows out of the accommodating chamber 1101, the mouthwash 30 flows from one end of the water outlet channel 121 close to the accommodating chamber 1101 to the recessed portion 122, and then flows upwards along the side wall of the recessed portion 122 to the water outlet hole 131. It is understood that the flow direction of the mouthwash 30 flowing from the position of the recessed portion 122 closest to the outer side wall surface of the neck 12 (i.e., the bottom of the recessed portion 122) toward the direction close to the water outlet hole 131 is referred to as "upward flow" in the present embodiment.

When the mouthwash 30 flows from the containing cavity 1101 to the water outlet channel 121 and enters the recessed portion 122 (for example, when the bottle body 10 is inclined as shown in fig. 6), the recessed portion 122 can temporarily store the mouthwash 30, the flow rate of the mouthwash 30 is reduced, and then the mouthwash flows from the recessed portion 122 to the water outlet hole 131 along the side wall surface of the recessed portion 122, in the process, the mouthwash 30 flows in a climbing manner, the flow rate of the mouthwash 30 is reduced again, and finally the mouthwash is poured from the water outlet hole 131 into a container for containing mouthwash for a user. It can be understood that when the bottle body 10 is at the same inclination angle, the outlet channel 121 with the recessed portion 122 has a lower outlet speed than the outlet channel 121 without the recessed portion 122, so that the mouthwash 30 can be slowly poured into other containers, the pouring amount of the mouthwash 30 is easier to control, and especially when the container for holding the mouthwash 30 has a smaller volume, if the pouring flow rate of the mouthwash 30 is too fast, the mouthwash 30 is easier to spill. That is, the oral cavity cleaning product of the present invention can reduce the pouring speed of the mouthwash 30 by providing the water outlet channel 121 having the recessed portion 122 on the neck portion 12 of the bottle body 10, so that the mouthwash 30 is not easily spilled to the outside of the container for holding the mouthwash 30, and the mouthwash 30 is not easily wasted.

Further, the recessed portion 122 in this embodiment has a downward slope section 1221 and an upward slope section 1222 connected to each other, wherein the downward slope section 1221 and the upward slope section 1222 are sequentially arranged along the direction from the main body portion 11 to the bottle mouth portion 13, and the boundary line between the two is shown by a straight line K in fig. 6. When the body 10 is positioned vertically (as in the condition of fig. 1 to 3), the level 31 of the mouthwash 30 is located at the bottom of the downhill segment 1221. When the bottle body 10 is tilted and the mouthwash 30 is poured out, the mouthwash 30 flows along the downward slope 1221 to the bottom of the concave portion 122 and then flows upward along the upward slope 1222 at a relatively slow flow rate.

Optionally, the descending slope section 1221 and the ascending slope section 1222 are connected by an arc transition in this embodiment, so that the mouthwash 30 can flow from the descending slope section 1221 to the ascending slope section 1222 at a relatively smooth flow rate, so as to prevent the mouthwash 30 from being agitated and not flowing out smoothly.

Further, in the height direction of the outlet passage 121, the cross-sectional area of the outlet passage 121 increases from the main body 11 to the outlet hole 131 and then decreases. So set up, can form foretell depressed part 122 at the great position of outlet channel 121 cross-sectional area, be convenient for cushion mouthwash 30 and slow down the speed of pouring out of mouthwash 30.

Furthermore, in the height direction of the outlet hole 131, the inner diameter of the outlet hole 131 is uniform, that is, the inner diameter of the outlet hole 131 does not change along the height direction, wherein the cross section of the outlet hole 131 is a section obtained by cutting the outlet hole 131 along the direction perpendicular to the axis of the bottle body 10, so that when the mouthwash 30 flows to the recessed portion 122, the flow rate is not changed by the change of the sectional area of the outlet channel 121, the mouthwash 30 can be smoothly poured into the container, and compared with the structure that the sectional area of the outlet channel 121 at the end close to the outlet hole 131 is gradually reduced, the shape of the outlet channel 121 on the bottle body 10 in the embodiment is more suitable for smoothly and slowly pouring the mouthwash 30.

Alternatively, the cross section of the water outlet passage 121 may be circular, elliptical or polygonal. It can be understood that the cross-sectional area of the water outlet channel 121 refers to that the water outlet channel 121 is cut along the axial direction perpendicular to the bottle body 10, and after the water outlet channel 121 is cut, a surface formed by the surrounding of the outer peripheral edge of the water outlet channel 121 is the cross-section of the water outlet channel 121. In this embodiment, the water outlet channel 121 is preferably configured to be circular, and has a simple structure and is convenient to process.

Further, the cross-sectional area of the outlet passage 121 near the end of the main body 11 is larger than that of the outlet hole 131. That is, the opening of the outlet channel 121 near the end of the receiving chamber 1101 is larger than the opening of the outlet hole 131 (i.e., the opening of the outlet channel 121 near the "end face" of the receiving chamber 1101 is larger than the opening of the outlet hole 131), so that the mouthwash 30 can enter the outlet channel 121 at a relatively slow speed and can be poured out at a relatively smooth speed. In addition, set up apopore 131 a little relatively, be convenient for more and be used for bearing the container alignment of mouthwash 30, and then be convenient for pour mouthwash 30 into to the container in, be difficult to appear the unrestrained condition of mouthwash 30.

Optionally, the ratio of the inner diameter L1 of the water outlet hole 131 to the maximum inner diameter L2 of the concave portion 122 in this embodiment is 0.7 to 0.8, such as L1: l2 ═ 0.7, L1: l2 ═ 0.72, L1: l2 ═ 0.74, L1: l2 ═ 0.76, L1: l2 ═ 0.78 or L1: l2 ═ 0.8, and the like. When L1: when the value of L2 is less than 0.7, the internal diameter L1 of apopore 131 is smaller, and the internal diameter of depressed part 122 is bigger, increases the velocity of flow of mouthwash 30 at apopore 131 department easily, and the in-process that mouthwash 30 emptys produces easily and splashes. When L1: when the value of L2 is greater than 0.8, the inner diameter L1 of outlet hole 131 is large and is not easily aligned with the container for holding mouthwash 30.

Optionally, the ratio of the inner diameter L3 of the water outlet channel 121 near the end of the main body 11 to the maximum inner diameter L2 of the recessed portion 122 in this embodiment is 0.82 to 0.99, such as L3: l2 ═ 0.82, L3: l2 ═ 0.84, L3: l2 ═ 0.86, L3: l2 ═ 0.98, L3: l2 ═ 0.9, L3: l2 ═ 0.93, L3: l2 ═ 0.95 or L3: l2 ═ 0.99, and the like. When L3: when the value of L2 is less than 0.82, the opening of the outlet channel 121 at the end near the main body 11 is smaller, and the maximum inner diameter L2 of the recessed portion 122 is larger, so that the mouthwash 30 is easily deposited on the recessed portion 122 at the same inclination angle, and is not convenient to pour into other containers; when L3: when the value of L2 is greater than 0.99, the maximum inner diameters L2 and L3 of the depressions 122 are closer to each other, resulting in a less effective or no effective reduction of the flow rate of the mouthwash 30. That is, in the present embodiment, by setting the ratio of the inner diameter L3 of the end of the water outlet channel 121 close to the main body 11 to the maximum inner diameter L2 of the recessed portion 122 to 0.82 to 0.99, the flow rate of the mouthwash 30 in the water outlet channel 121 can be reduced, and the mouthwash 30 in the water outlet channel 121 can be poured into other containers.

In the present embodiment, the ratio of the height D1 of the finish portion 13 to the height D of the neck portion 12 is 1/5 to 1/3, for example, D1: d-1/5, D1: d-1/4 or D1: d-1/3. When D1: when the value of D is less than 1/5, the mouth 13 is short, and it is difficult to smoothly guide the mouthwash 30 into the carrying container; when D1: when the ratio of D is greater than 1/3, the mouth portion 13 is relatively long, and the corresponding recessed portion 122 will be relatively short due to the relatively long mouth portion 13 under the water outlet channel 121 with the same length, which is not convenient for slowing down the flow rate of the mouthwash 30.

The bottle mouth 13 of the present embodiment has at least two rings of water retaining rings 133, and the water retaining rings 133 can be used to stop the mouthwash 30 flowing out of the water outlet 131 and along the outer wall surface of the bottle mouth 13. When the mouth wash 30 is poured and the bottle body 10 is returned to the normal position (the state shown in fig. 1), part of the mouth wash 30 inevitably flows along the outer wall surface of the mouth portion 13 from the outlet hole 131. Because the protruding at least two rings of water retaining ring 133 that are equipped with of bottleneck portion 13 periphery, through the effect of this water retaining ring 133, can block the mouthwash 30 that flows from apopore 131, avoid mouthwash 30 to flow downwards along the lateral wall face of bottleneck portion 13, and then prevent neck 12 and even main part 11 outside wall face from being adhered to by mouthwash 30 and producing and glue thick sense, the user of being convenient for uses.

In some embodiments of the present invention, the water deflector 133 may be set to two rings, or may be set to three rings or more than three rings, fig. 7 to 8 of the present invention show a case where the water deflector 133 is set to two rings, and by setting the water deflector 133 to two rings, not only a good water deflector effect can be achieved, but also a problem of increase in processing cost when the water deflector 133 is set to multiple rings can be avoided. In order to facilitate the distinction, in the present embodiment, the two rings of water retaining rings 133 are respectively identified as a first water retaining ring 133a and a second water retaining ring 133b, wherein the first water retaining ring 133a and the second water retaining ring 133b are disposed at the neck portion 12 at intervals along the direction from the water outlet hole 131 to the main body portion 11, and the first water retaining ring 133a and the second water retaining ring 133b can stop the mouthwash 30 flowing along the outer side wall surface of the bottle mouth portion 13 twice.

The first water retaining ring 133a in this embodiment is an annular structure disposed along the outer periphery of the neck portion 12, and the annular structure is integrally formed with the bottle mouth portion 13, and the cross section of the first water retaining ring 133a is square. Of course, in other embodiments of the present invention, the cross section of the first water deflector 133 may be a semicircular shape. Further, the first retaining ring 133a in this embodiment has a first ring surface 1331 disposed near the water outlet hole 131, and an included angle between the first ring surface 1331 and an outer side wall surface of the bottle opening 13 at a junction thereof is 90 °. That is to say, the first ring surface 1331 in this embodiment is a plane perpendicular to the outer wall surface of the bottle opening 13 at the position where the first ring surface 1331 is connected to, when the mouthwash 30 flows from the water outlet 131 to the first ring surface 1331 along the outer wall surface of the bottle opening 13, the first ring surface 1331 and the outer wall surface of the bottle opening 13 have a 90 ° corner instead of an obtuse angle (i.e., the first ring surface 1331 inclines toward the direction away from the water outlet 131), so that the mouthwash 30 does not easily move toward the side away from the water outlet 131 beyond the first ring surface 1331, and a good water blocking effect can be achieved. Meanwhile, in the actual processing process, the bottle body 10 is formed by die sinking and processing through a die, so that the first ring surface 1331 and the outer side wall surface of the bottle opening part 13 are arranged at 90 degrees instead of being arranged at an acute angle (namely, the first ring surface 1331 inclines towards one side close to the water outlet hole 131), the bottle body 10 is more convenient to demould, and the production and processing cost of the bottle body 10 can be reduced.

Referring to fig. 1, 5 to 10, the second water stop ring 133b in this embodiment has a second annular surface 1332 disposed at the top end of the bottle mouth portion 13, the second annular surface 1332 is inclined towards a direction away from the top end of the bottle mouth portion 13, the bottle cap assembly 20 includes a sealing cover 21, and when the sealing cover 21 is fastened on the neck portion 12, an end of the sealing cover 21 abuts against the second annular surface 1332. Because the second ring surface 1332 is inclined towards the direction deviating from the top end of the bottle mouth part 13, when the sealing outer cover 21 is propped against the second ring surface 1332, the effect of propping against more and more can be shown, and a good limiting and sealing effect can be achieved on the sealing outer cover 21. In addition, when the end of the sealing cover 21 abuts against the second ring surface 1332, the end of the sealing cover 21 tends to be supported by the second ring surface 1332 from the inside, and the sealing cover 21 is not easily deformed by being squeezed during transportation and use of the oral cleaning product, so that the service life of the oral cleaning product in the embodiment can be prolonged to some extent. Meanwhile, when the end of the sealing outer cover 21 abuts against the second annular surface 1332, the gap between the end of the sealing outer cover 21 and the second annular surface 1332 is small, foreign matters such as dust are not easy to enter the sealing outer cover 21 and even the inside of the bottle body 10 from the gap between the sealing outer cover 21 and the bottle body 10, and when the sealing outer cover 21 is used as a container for containing the mouthwash 30, the sealing outer cover 21 is not required to be cleaned, and a good sealing effect can be achieved for a long time.

Alternatively, the included angle a between the second ring surface 1332 and the outer side wall surface of the bottle mouth portion 13 at the junction therebetween in the present embodiment is 95 ° to 110 °, for example, 95 °, 98 °, 100 °, 103 °, 106 °, or 110 °. When the included angle between the second ring surface 1332 and the outer wall surface of the bottle mouth 13 at the joint of the two is less than 95 degrees, the inclined angle of the second ring surface 1332 is not enough, and the second ring surface is not convenient to abut against the end of the sealing outer cover 21 so as to achieve the purpose of improving the sealing effect; when the included angle between the second annular surface 1332 and the outer side wall surface of the bottle mouth part 13 at the position connected with the second annular surface 1332 is greater than 110 degrees, the inclination of the second annular surface 1332 is larger, at this time, the included angle between the outer side wall surface of the bottle mouth part 13 and the second annular surface 1332 is larger, when the mouthwash 30 flows to the second annular surface 1332 along the outer side wall surface of the bottle mouth part 13, the mouthwash flows more easily in the direction away from the water outlet hole 131, and the water retaining effect is poor. That is to say, in this embodiment, the included angle between the outer side wall surfaces of the second ring surface 1332 and the bottle mouth portion 13 at the connection position is set within the range of 95 ° to 110 °, so that not only a good sealing effect can be achieved by matching with the sealing outer cover 21, but also a good protection effect can be achieved for the sealing outer cover 21.

Further, one end of the second water stop ring 133b away from the central axis of the bottle mouth portion 13 in this embodiment is provided with a chamfer 1333, the chamfer 1333 is a rounded angle, and by the action of the chamfer 1333, the second water stop ring 133b can be well matched with the end of the sealing outer cover 21 to further improve the sealing performance of the sealing outer cover 21 in this embodiment on the water outlet hole 131.

In the process of actually using the mouthwash 30, one bottle of mouthwash 30 needs to be used for a plurality of times, that is, the sealing outer cover 21 needs to be repeatedly covered on the mouth portion 13 and abut against the second water retaining ring 133b, so the second water retaining ring 133b in this embodiment needs to be thicker, and the second water retaining ring 133b is prevented from being damaged by the top. Specifically, in the height direction of the bottle mouth portion 13, the thickness D1 of the end of the second water stop ring 133b close to the central axis of the bottle mouth portion 13 is greater than or equal to the thickness D2 of the first water stop ring 133a, so that a sufficient space can be reserved at the position of the bottle mouth portion 13 close to the water outlet hole 131 to set the second water stop ring 133b, and the situation that the first water stop ring 133a is too wide and the second water stop ring 133b needs to be moved down is avoided, and finally the sealing outer cover 21 cannot abut against the second water stop ring 133b is caused.

Exemplarily, the second water retaining ring 133b in this embodiment is suspended at the top end of the neck portion 12 (i.e. the neck portion 12 is away from the one end of the main body portion 11), and thus, even if the mouthwash 30 flows to the second water retaining ring 133b along the outer side wall surface of the bottle mouth portion 13, the mouthwash 30 can be effectively retained by the second water retaining ring 133b suspended at the top end of the neck portion 12, and the mouthwash 30 is difficult to flow downward along the outer side wall surface of the neck portion 12 over the second water retaining ring 133 b.

In some embodiments of the present invention, the distance L5 between the first retaining ring 133a and the top end of the water outlet hole 131 (i.e. the end away from the main body 11) is 10mm to 14mm, such as 10mm, 12mm or 14mm, and the distance L6 between the second retaining ring 133b and the first retaining ring 133a is 5mm to 7mm, such as 5mm, 6mm or 7 mm; the distance L7 between the second water baffle 133b and the top end of the water outlet hole 131 is 18mm to 22mm, such as 18mm, 19mm, 20mm, 21mm or 22 mm. The first water deflector 133a and the second water deflector 133b satisfy the above parameter ranges, thereby achieving a good waterproof effect.

Alternatively, the height H1 of the protrusion of the first water stop ring 133a is smaller than the height H2 of the protrusion of the second water stop ring 133b in the radial direction of the bottle mouth portion 13, so that the first water stop ring 133a does not interfere with the sealing cover 21 during the process that the sealing cover 21 abuts against the second water stop ring 133 a. In addition, since the second water deflector 133b is the rearmost water deflector step, the higher the protrusion height H2, the better the water deflector effect.

Referring to fig. 1 to 3, the mouth wash 30 of the present embodiment further comprises a cap assembly 20, wherein the cap assembly 20 comprises an outer sealing cap 21 and an inner sealing cap 22, the inner sealing cap 22 is detachably disposed at the water outlet 131 of the mouth portion 13, and the outer sealing cap 21 is detachably disposed on the neck portion 12 and on the outer side of the inner sealing cap 22. Through the effect of sealed enclosing cover 21 and sealed inner cup 22, be convenient for carry out double-deck sealing to apopore 131, it is sealed effectual, the user of being convenient for uses.
