Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Referring to fig. 1 and 2, an aluminum-plastic cover for medical packaging includes an aluminum cover 100 and a plastic cover 200 covering the top of the aluminum cover 100, wherein the plastic cover 200 is detachably disposed on the aluminum cover 100. In practical use, the user needs to remove the plastic cap 200 from the aluminum cap 100 and then break the aluminum cap 100 to open the medicine bottle further.

Referring to fig. 2 and 3, the outer side wall of the plastic cover 200 is uniformly provided with anti-slip lines 210, and the bottom of the plastic cover 200 is further provided with snap-fit petals 220, and the snap-fit petals 220 can be fixed on the plastic cover 200 by means of hot riveting. In this embodiment, the number of the fastening petals 220 can be uniformly arranged according to the requirement, for example, 4, 5, 6 or 8, and preferably 6. Taking any one of the buckling petals 220 as an example, a precut notch 221 is further arranged at the joint of the buckling petal 220 and the plastic cover 200, and the precut notch 221 can be respectively arranged on two sides of the buckling petal 220 in the width direction, so that the buckling petal 220 can be conveniently removed from the plastic cover 200.

Referring to fig. 4, the aluminum cap 100 includes a cylindrical portion 110, and the cylindrical portion 110 has a circular cylindrical structure and may be used to cover an opening of a medicine bottle. The side wall of the cylindrical portion 110 is integrally formed with a tearing portion 120, and the cylindrical portion 110 is further formed with tearing slits 121 on both sides of the tearing portion 120 in the width direction, so that a user can easily tear the tearing portion 120 from the aluminum cap 100 through the tearing slits 121. A pull ring 130 is integrally formed on the upper side of the tearing part 120, and the pull ring 130 is folded into a horizontal state relative to the tearing part 120; in use, a user can pull the tear portion 120 through the pull tab 130 and tear the tear portion 120 off the aluminum lid 100.

Referring to fig. 5, a backing ring 140 is further embedded inside the cylindrical portion 110, a fastening opening 141 is formed through the center of the backing ring 140, and the backing ring 140 abuts against the top of the inside of the aluminum lid 100. The top of the backing ring 140 is also concavely formed with an annular groove 142; when the pull ring 130 is in a horizontal state, the pull ring 130 can be embedded in the annular groove 142, so that the appearance is ensured. A folded edge 143 is further formed by bending the outer side of the grommet 140, and the folded edge 143 abuts against the inner side wall of the cylindrical portion 110. In order to ensure the stability, a plurality of welding points 300 are further arranged on the inner side wall of the cylindrical part 110, the welding points 300 are uniformly distributed on the circumference, and the folding edge 143 can be welded and fixed on the inner side wall of the cylindrical part 110; in use, the weld 300 not only ensures substantial stability of the backing ring 140, but also facilitates the user in removing the backing ring 140 from the aluminum lid 100.

In practical use, the fastening petals 220 are embedded into the fastening openings 141 and are reversely fastened to the inner side edges of the fastening openings 141, so that the plastic cover 200 is stably fastened to the top of the aluminum cover 100, and the integrity of the aluminum cover 200 is ensured. As shown in fig. 1 and 5, in order to facilitate the user to remove the plastic cover 200 from the aluminum cover 100 when necessary, the edge of the inner side of the backing ring 140 is further provided with a cutting portion 144 extending inwards, the cutting portions 144 may be arranged in a one-to-one correspondence with the fastening petals 220, and each cutting portion 144 is located at a gap of each fastening petal 220. Taking any cutting portion 144 as an example, the cutting portion 144 is formed with cutting edges 145 on both sides close to two adjacent snap-fit petals 220, the cutting edges 145 may be configured into an arc-shaped structure, and the curvature center of the arc-shaped edge of any cutting edge 145 is located on one side of the cutting edge 145 departing from the adjacent snap-fit petals 220.

The working principle of the embodiment is as follows: in practical use, when the user rotates the plastic cover 200, the cutting portion 144 rotates relative to the plastic cover 200; in the process, each cutting part 144 cuts each fastening petal 220 from the bottom of the plastic cover 200 through the cutting edge 145, so that each fastening petal 220 loses the fastening effect on the backing ring 140, and the plastic cover 200 is conveniently separated from the aluminum cover 100. Then, the user can tear the tearing portion 120 from the cylindrical portion 110 by the pull ring 130, thereby conveniently breaking the aluminum cap 100 and facilitating the user to further open the medicine bottle. Through this kind of mode, under the prerequisite of guaranteeing the sealed effect of medicine bottle, convenience of customers opens this plastic-aluminum lid 200, improves the convenience that the user used greatly.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
