Description

A kind of draw-ring type aluminium-plastic cap

Technical field

The utility model relates to a kind of tearing aluminium-plastic cap, and particularly a kind of draw-ring type tearing aluminium-plastic cap, belongs to draw-ring type aluminium-plastic cap technical field of structures.

Background technology

At present, draw-ring type aluminium-plastic cap answers its convenience opened to be widely used in the sealing of beer, fruity alcoholic beverage, energy drink, functional beverage and various fruit juice.Its structure mainly comprises lid and draw ring two parts, during unlatching, only upwards need pull draw ring with hand, can whole bottle cap be driven to depart from bottleneck the tongue tear at lid top.

In the use procedure and market feedback of reality, find that traditional draw-ring type aluminium-plastic cap exists following technological deficiency: 1, due to the structure design of draw ring evagination, body after causing encapsulating is very easily touched in handling process to be arrived, and produces bottleneck and loosens even unexpected situation of tearing unlatching.2, finger tip is when pulling draw ring, and owing to not borrowing force and any protection, aluminium lid not easily departs from bottleneck, and the lift power of finger only can be relied on to be torn by aluminium lid, and the aluminium lid edge simultaneously torn very easily hurts finger, and safety is not enough.3, sealing property is not good, and external oxygen easily enters in bottle, affects the freshness of liquid in bottle.

Summary of the invention

The utility model is intended to solve the technological deficiencies such as existing draw-ring type aluminium-plastic cap opens difficulty, draw ring evagination easily produces unexpected unlatching, easily hurt hand, safety deficiency, leak tightness are not good, and then provide one have scientific structure design rationally, the safety labor-saving that operates, can not produce to open by mistake and open, not easily hurt hand and the excellent draw-ring type aluminium-plastic cap of leak tightness.

For solving the problem, the technical scheme that the utility model adopts is:

A kind of draw-ring type aluminium-plastic cap, comprise lid 1 and be connected to the draw ring 2 of its side, its special character is, the top of described draw ring 2 has tearing of being connected with described lid 1 top cut out portion and holds 2-1, the bottom of described draw ring 2 has end of thread 2-2 in flexibility that laminating is fastened on bottleneck periphery, described in tear end 2-1 bottom be provided with the power of borrowing be resisted against on described lid 1 when draw ring lift is opened and support salient point 3;

The both sides of described support salient point 3 are locked on described lid 1 when being provided with draw ring tearing, when avoiding opening finger by the safe earflap 4 hurt;

In described flexibility, end of thread 2-2 has the warp architecture matched with described bottleneck circumferential profile;

In order to increase the sealing property of bottle cap further, ensure the freshness of contained liquid, described lid 1 inside be covered with can isolating exterior oxygen, enter bottleneck oxygen in tourie process of assembling resistance oxygen in pad 5;

The triangle that described power of borrowing supports the planform of salient point 3 and can be designed to according to actual needs give prominence to, oblong, spherical or other can play the shape and structure of same function.

A kind of draw-ring type aluminium-plastic cap of the present utility model, its simple structural design is reasonable, emphasis solve the safety that existing draw-ring type aluminium-plastic cap exists not enough, not easily to open and the technical matters such as sealing property is inadequate, adopt lever principle, add power of borrowing and support the problem that salient point effectively can solve unlatching effort, by draw ring profile design being become the shape matched with bottleneck periphery, avoid the problem that bottleneck is surprisingly opened; By adding safe earflap in draw ring both sides, can, when draw ring is opened, make the end of earflap be locked to the side of lid, keeping the safety distance between finger and lid, available protecting finger not be hurt.

Detailed description of the invention

With regard to accompanying drawing 1-3, a kind of draw-ring type aluminium-plastic cap of the utility model is described in detail below below.

Embodiment 1

A kind of draw-ring type aluminium-plastic cap, comprise lid 1 and be connected to the draw ring 2 of its side, the top of described draw ring 2 has tearing of being connected with described lid 1 top cut out portion and holds 2-1, the bottom of described draw ring 2 has end of thread 2-2 in flexibility that laminating is fastened on bottleneck periphery, described in tear end 2-1 bottom be provided with the power of borrowing be resisted against on described lid 1 when draw ring lift is opened and support salient point 3; The both sides of described support salient point 3 are locked on described lid 1 when being provided with draw ring tearing, when avoiding opening finger by the safe earflap 4 hurt; In described flexibility end of thread 2-2 have match with described bottleneck circumferential profile warp architecture; In order to increase the sealing property of bottle cap further, ensure the freshness of contained liquid, described lid 1 inside be covered with can isolating exterior oxygen, enter bottleneck oxygen in tourie process of assembling resistance oxygen in pad 5; The triangle that described power of borrowing supports the planform of salient point 3 and can be designed to according to actual needs give prominence to, oblong, spherical or other can play the shape and structure of same function.

A kind of draw-ring type aluminium-plastic cap of the present utility model, its simple structural design is reasonable, emphasis solve the safety that existing draw-ring type aluminium-plastic cap exists not enough, not easily to open and the technical matters such as sealing property is inadequate, adopt lever principle, add power of borrowing and support the problem that salient point effectively can solve unlatching effort, by draw ring profile design being become the shape matched with bottleneck periphery, avoid the problem that bottleneck is surprisingly opened; By adding safe earflap in draw ring both sides, can, when draw ring is opened, make the end of earflap be locked to the side of lid, keeping the safety distance between finger and lid, available protecting finger not be hurt.
