Description

Improved structure of cover of pot

Technical Field

The invention relates to a cover, in particular to an improved structure of a cover of a pot, and belongs to the field of pots for containing particles such as medicines.

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.

Although the cans are improved in taiwan new model nos. 98202822 and 98214536, the structures of the two patents are found to be difficult to mass-produce in the manufacturing process after the actual manufacturing and commercialization, which causes the manufacturing efficiency to be reduced and the cost to be increased.

Furthermore, although the structure of the new model 98214536 shows 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 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: a lid improvement structure of a can, comprising:

the movable cover body comprises a symbol rotary ring, a claw seat, a containing groove body and an outer shell, wherein the surface of the symbol rotary ring is provided with symbols, 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 shell is an annular body, the side wall of the outer 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 shell;

the upper part of the lock seat body extends to form an insertion tube body, the insertion tube body is inserted into the claw seat and sleeved on the periphery of the accommodating groove body, the movable cover body slides up and down along the insertion tube body, and the side wall of the insertion tube body is provided with a first opening;

the arc plate is inserted into the lock base body, and two sides of the arc plate are abutted to the two convex strips;

the top of the ring sleeve body is provided with an upper ring concave part and covers the bottom of the lock seat body, and the bottom of the arc-shaped plate slides in the upper ring concave part.

The beneficial effects of the invention are:

when the medicine in the pot needs to be taken out, the inserting tube body is inserted into the claw seat and sleeved on the periphery of the containing groove body, the movable cover body slides up and down along the inserting tube body, the movable cover body is pulled up to a preset height and then rotates clockwise, the arc-shaped plate is inserted into the locking seat body and is positioned between the two convex strips of the containing groove body, the convex strips drive the arc-shaped plate to rotate clockwise, when the opening two of the arc-shaped plate is aligned with the opening one of the inserting tube body, the rotation is stopped, namely, the medicine in the pot can be poured out after the opening two is aligned with the opening one, and the phenomenon that the medicine is poured out due to the fact that the opening of the pot is too large can be avoided; in synchronization with the above, since the symbol rotary ring is sleeved on the periphery of the claw body and the barb and the inclined notch are matched to push and block to drive the symbol rotary ring to rotate in one direction, the barb rotates clockwise and cannot drive the symbol rotary ring to rotate, the outer shell rotates to drive the symbol displayed on the display port to switch to the next symbol (for example, mon becomes Tue), so that when taking medicine, the symbol displayed on the display port is switched to the next symbol to remind the patient that the medicine is taken;

after the medicines are taken out, the movable cover body is rotated anticlockwise, the arc-shaped plate is inserted into the lock base body and is positioned between the two convex strips of the accommodating groove body, the convex strips drive the arc-shaped plate to rotate, when the strip-shaped holes are aligned with the first openings, the rotation is stopped, and the strip-shaped holes can seal the first openings to prevent the medicines from falling out; meanwhile, the symbol rotary ring is sleeved on the periphery of the claw body, the barb is matched with the inclined notch to push and block the symbol rotary ring so as to drive the symbol rotary ring to rotate in a single direction, the barb rotates anticlockwise to drive the symbol rotary ring to rotate along with the display opening, the symbol displayed by the display opening is kept as the next symbol, and the movable cover body is pressed down to be attached to the lock seat body.

The novel medicine taking device is novel in design, convenient and practical, can accurately record the medicine taking times, is convenient for a patient to place the second type of medicine due to the containing space of the containing groove body, and has wide application prospect.
