Background

The conventional medicine can has a large opening, and when the medicine particles are poured, the problem that the number of the particles to be taken out cannot be accurately poured out, a large number of medicine particles are poured out, or the medicine particles are carelessly scattered to the ground is easily caused, and some patients often have the situation that whether the patients take the medicine or not is often determined, and the patients take the medicine repeatedly or do not take the medicine at all.

The new taiwan models 98202822 and 98214536 in taiwan are improved, but the structures of the two patents are found after the actual manufacturing and commercialization, and the mold is difficult to produce in large quantity in the manufacturing process, so that the manufacturing efficiency is reduced, and the cost is increased.

Furthermore, although the structure of the new model 98214536 can record and display the number of times that the cap is opened for the patient to know whether the patient has taken the medicine, the movable cap of the cap structure must be pulled upward to have an opening for the medicine in the can to be poured out directly, and then the movable cap is rotated to indirectly drive the symbol rotary ring to rotate, so as to switch and record the number of times of use. The operation action sequence formed by the cover structure is easy to cause incomplete medicine taking operation action of a patient, so that the display of the use record times is incorrect.

In addition, through market research, people taking medicines daily occasionally have emergencies and need rapid inhibition of first-aid medicines, so that one pot is needed to store the first-aid medicines, the first-aid medicines are not needed to be taken daily, and the pot storing the first-aid medicines cannot be found timely when the emergencies occur, so that the illness state is delayed.

Therefore, how to provide a lid structure of a can capable of accurately recording the number of times of use and having a storage function constitutes a problem that needs to be solved by those skilled in the art.

Disclosure of Invention

The invention provides an improved structure of a cover of a pot, which solves the technical problems that the existing cover can not accurately record the use times and does not have a storage function.

The technical scheme for solving the technical problems is as follows: an improved structure of a lid for a can, comprising:

the movable cover body comprises a symbol rotary ring, a claw seat, a containing groove body and an outer ring shell, wherein the surface of the symbol rotary ring is provided with a symbol, and the inner wall of the symbol rotary ring is provided with an inclined notch; the claw seat is an annular body, two corresponding claw bodies extend downwards from the inner wall of the claw seat, each claw body is provided with a barb, the symbol rotary ring is sleeved on the periphery of each claw body, and the barbs and the inclined notches are matched with each other to push and block the symbol rotary ring so as to drive the symbol rotary ring to rotate in a single direction; the containing groove body is provided with a containing space, and two raised lines are arranged on the outer wall of the containing groove body at intervals; the outer ring shell is an annular body, the side wall of the outer ring shell is provided with a display opening, the display opening corresponds to a symbol of the symbol rotary ring, the groove containing body is inserted into the claw seat, and the groove containing body and the claw seat are both fixed in the outer ring shell;
