Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
The utility model provides a cover of an aluminum foil tearing ring, which comprises an upper cover 1, a lower cover 2 and an aluminum foil gasket 3, as shown in figure 1; the upper cover 1 is in threaded connection with the lower cover 2; the lower cover 2 is provided with a positioning part 4 for overlapping with the opening of the bottle body; the aluminum foil gasket 3 is fixed at the lower end of the positioning part 4, and the pull ring 5 is fixed at the upper end of the aluminum foil gasket 3; wherein, the aluminum foil gasket 3 is connected with the pull ring circular ring 5 in a heat-sealing way, and the aluminum foil gasket 3 is connected with the bottle mouth in a heat-sealing way. In practical application, the aluminum foil gasket 3 is a double-sided aluminum foil gasket without paper; when the cap needs to be opened, the aluminum foil gasket 3 moves upwards along with the pull ring 5 only by pulling the pull ring 5, so that the aluminum foil gasket 3 is torn and separated from the bottle opening, and the cap is opened. In the production process of the lower cover 2, the pull ring 5 of the lower cover 2 and the aluminum foil gasket 3 are subjected to online heat sealing and assembled with the upper cover 1 to form an integrated aluminum foil gasket cover; in the process of filling the contents in the bottle, the aluminum foil gasket 3 is thermally sealed with the bottle mouth, so that the high-sealing packaging effect of the product is achieved. For some food products where barrier requirements are high such as: canned fruit, canned meat and powdered milk are all suitable.
Further, as shown in fig. 1 and 2, the tab ring 5 includes a tab portion 51, a support portion 52, and a ring portion 53; one end of the support part 52 is fixed with the pull ring part 51, and the other end is fixed with the ring part 53; the circular ring portion 53 is fixed to the aluminum foil gasket 3. When the cap is opened, fingers stretch into the pull ring part 51, the pull ring part 51 is pulled, the pull ring part 51 pulls the supporting part 52 to move upwards, the supporting part 52 drives the circular ring part 53 to move upwards, the aluminum foil gasket 3 fixed at the bottom of the circular ring part 53 moves upwards along with the circular ring part 53, and therefore the aluminum foil gasket 3 is completely separated from the bottle mouth.
Optionally, the outer wall of the circular ring part 53 is provided with a plurality of connecting blocks 6 surrounding the circular ring part 53; one end of the connecting block 6 is fixed on the outer wall of the circular ring part 53, and the other end is fixed on the inner wall of the lower cover 2. The connecting block 6 fixes the circular ring part 53 on the inner wall of the lower cover 2, thereby reducing the extrusion of the circular ring part 53 on the aluminum foil gasket 3 and ensuring that the aluminum foil gasket 3 cannot be damaged when the bottle cap is not opened.
In practical application, the vertical cross section of the connecting block 6 can be unlimited in shape, in this embodiment, the vertical cross section of the connecting block 6 is a right triangle, a right-angled edge is fixed on the circular ring part 53, and another right-angled edge is fixed on the aluminum foil gasket 3. The connecting block 6 is fixed on the aluminum foil gasket 3, so that the stability of the aluminum foil gasket 3 can be further improved, meanwhile, the connecting strength of the aluminum foil gasket 3 and the circular part 53 is improved, and the circular part 53 can conveniently drive the aluminum foil gasket 3 to be separated from the bottle opening; since one vertex of the connecting block 6 is connected to the inner wall of the lower cover 2, the connecting block 6 does not generate too much resistance to affect the circular ring portion 53 to move upward when the pull ring portion 51 is pulled.
In practical applications, the cross section of the connecting block 6 may have an unlimited shape, and in this embodiment, in order to further reduce the influence of the connecting block 6 on the upward movement of the circular ring portion 53, the cross section of the connecting block 6 is an isosceles triangle, and the top angle thereof is fixed on the inner wall of the lower cover 2, and the bottom angle thereof is fixed on the outer wall of the circular ring portion 53.
Further, in order to facilitate pulling the ring portion 51, in the present embodiment, an anti-slip pattern is disposed on a side of the ring portion 51 facing the circular portion 53; when pulling collar portion 51, stretch into collar portion 51 with the finger to the upwards pull, the friction of slip resistant line can increase collar portion 51 and finger, and more person of facilitating the use pulls collar portion 51.
Optionally, the inner wall of the lower cap 2 is provided with a buckling part 8 for fixing the lower cap 2 on the bottle mouth. The lower cover 2 is fixed at the bottleneck of the bottle body through the buckling part 8, and the high-sealing packaging effect of the product is achieved.
Furthermore, the section of the buckling part 8 is streamline, the curvature of the upper end is larger, and the curvature of the lower end is smaller; when assembling the lid on the bottle, because the lower extreme camber of buckling parts 8 is less, can conveniently with the lid lock in bottleneck department, and because the upper end camber of buckling parts 8 is great, can improve the connection stability of lower cover 2 and bottle, avoid lower cover 2 to break away from the bottle.
Further, as shown in fig. 3, in order to improve the connection strength between the circular portion 53 and the aluminum foil gasket 3, the lower end of the circular portion 53 is provided with a first heat sealing line 7 in the present embodiment; when carrying out online heat-seal with aluminium foil gasket 3 and ring portion 53, aluminium foil gasket 3 laminates mutually with first heat seal line 7, has increased the heat-seal area of aluminium foil gasket 3 with ring portion 53, improves the joint strength of aluminium foil gasket 3 and ring portion 53.
Optionally, a second heat-sealing line 9 is provided at the lower end of the positioning portion 4. The positioning part 4 can tightly support the aluminum foil gasket 3 at the bottle mouth through the second heat sealing line 9, so that the aluminum foil gasket 3 remained at the bottle mouth is prevented from losing support and falling into the bottle after the pull ring circular ring 5 is pulled out; meanwhile, the sealing effect of the lower cover 2 on the bottle mouth is effectively improved.
As shown in fig. 4, when the lid of the aluminum foil tear tab is produced, the upper lid 1 and the lower lid 2 are molded by an injection molding machine, the molded lower lid 2 is heat sealed with the aluminum foil gasket 3 by an aluminum foil gasket machine (not limited to a pneumatic electromagnetic induction aluminum foil sealing machine, an electromagnetic wave aluminum foil sealing machine, etc.), the production of the lower lid 2 is completed, and the lower lid 2 and the upper lid 1 are assembled into a completed lid.
Optionally, the combination mode of the cover can be an upper cover and a lower cover combination, a flip cover and the like, the heat sealing of the cover and the double-sided aluminum foil gasket without paper can be completed on line or off line, and the aluminum foil gasket can be made of coiled materials or sheets.
In the implementation process, when opening the lid, pulling collar portion 51 makes ring portion 53 drive aluminium foil gasket 3 and shifts up to make aluminium foil gasket 3 break away from the bottleneck, can conveniently tear aluminium foil gasket 3, avoid aluminium foil gasket 3 to fall into in the bottle.
The utility model discloses a lid of aluminium foil tear ring can conveniently tear aluminium foil gasket 3, reduces consumer exclusive use hand or other instrument and tears aluminium foil gasket 3, also avoids aluminium foil gasket 3 to tear or tear the use that the piece of process falls into the bottle influence product because of the part simultaneously.
It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
