Abstract

The utility mode relates to a new bottle cover which is able to automatically carve the airproofing film of the bottle mouth and conquers a plurality of abuses caused by adopting the piercing method to open the airproofing film. The utility model comprises three parts: a cover body(1), a knife edge(2) and a gasket(3). The gasket(3) is arranged between the lower part of the cover body(1) and a bottle body(5), taking off the gasket when needs to carve the airproofing film so as to provide spaces for the cover body(1) unceasingly moving the knife edge to carve the airproofing film. Because adopting the utility model to open the airproofing film on the bottle mouth, reduces the bother of the users and simultaneously conquers the abuse that the airproofing film relics baffles the objects be taken out. The utility model also has the advantages of simple structure and convenient operation.

Description

A kind of bottle cap

Technical field

The utility model relates to a kind of bottle cap, especially a kind of novel bottle cap that can cut the bottleneck diaphragm seal voluntarily.

Background technology

At present, various types of bottles generally adopt the way that diaphragm seal is set at bottleneck, realize sealing, leakproof, fresh-keeping, or are convenient to transport the purpose of storage.Though the setting of diaphragm seal has a lot of benefits, puncture diaphragm seal yet will seek hard thing in use in addition, brought a lot of troubles to the user, especially when the user can't find suitable hard thing at one's side.In addition, when employing punctured the diaphragm seal mode, the diaphragm seal relic was still stayed the bottleneck edge, give to pour out bottle an interior thing and bring certain obstruction, even do not go out, this in we live usually, the problem that usually occurs during as use medicine bottle, beverage bottle.

Summary of the invention

The utility model is intended at the bottle with diaphragm seal, proposes a kind of novel bottle cap that can cut the bottleneck diaphragm seal voluntarily.Overcome and adopt the mode of puncturing to open many drawbacks of existence diaphragm seal.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is as follows:

A kind of bottle cap comprises lid, it is characterized in that: be provided with packing ring between lid bottom and the bottle; Be provided with the blade of cutting bottleneck diaphragm seal at lid inwall top.

Packing ring is connected with lid lower circumference or bottleneck bottom.

Be connected with lid or bottleneck breakpoint formula on the packing ring circumference.

Packing ring is provided with and draws mouth, and is provided with easy breakpoint on its next door.

Blade is arranged on the tangent line of interior garden week of bottleneck.

Advantage of the present utility model is:

When opening the bottleneck diaphragm seal, need not seek the hard thing that punctures diaphragm seal in addition, reduce user's trouble, overcome the mode that punctures simultaneously and hindered the drawback of getting thing because of retaining the diaphragm seal relic on the bottleneck.And the utility model also has advantage simple in structure, easy to operate.

The specific embodiment

The utility model proposes a kind of novel bottle cap that can cut the bottleneck diaphragm seal voluntarily, adopt the mode of puncturing to open the many drawbacks that exist to diaphragm seal to overcome.

This bottle cap is made up of three parts: lid 1, blade 2, packing ring 3.

Blade 2 is positioned at lid 1 inwall top, and is arranged on all tangent lines in bottleneck 4 interior gardens, is convenient to diaphragm seal is cut along circle in the bottleneck.

Packing ring 3 is between lid 1 bottom and bottle 5, and it has two effects, and the one, when not needing cutting sealing film 6, be used to hinder blade 2 and touch diaphragm seal 6; The 2nd, when needs cutting sealing film 6,, lid 1 provides the space for continuing to move down.Here, packing ring 3 has three kinds of connection modes, and one, be enclosed within bottleneck 4 bottoms and independently exist, be not connected with lid 1 or bottle 5; Two, be connected (see figure 1) with lid 1 bottom breakpoint formula; Three, be connected with bottleneck 14 bottom bottles 5 breakpoint formulas.Also can on packing ring 3, be provided with in addition and draw mouth 7, and easy breakpoint is set on its next door.According to the difference of connection mode, removing packing ring 3 also has multiple mode, and one, at first kind of connection mode, can when opening bottle cap, take off packing ring 3; Two, can under the effect of easy breakpoint, slightly firmly draw mouth 7 in conjunction with drawing mouthful 7 structures for second and third kind mode, packing ring 3 is just broken, and breaks away from lid 1 or bottle 5.

After packing ring 3 took off, it took up space and continues to provide condition to bottom offset just for blade 2.Twisting lid 1 blade 2 just along bottleneck 4 interior garden cutting sealing films 6, stops cutting near a week time, take off lid 1, and the diaphragm seal 6 of opening or tear no longer retains the diaphragm seal relic on the bottleneck 4, conveniently get thing.

Claims

1, a kind of bottle cap comprises lid (1), it is characterized in that: be provided with packing ring (3) between lid (1) bottom and the bottle (5); Be provided with the blade (2) of cutting bottleneck diaphragm seal (6) at lid (1) inwall top.

2, a kind of bottle cap according to claim 1 is characterized in that: packing ring (3) is connected with lid (1) lower circumference or bottleneck (4) bottom.

3, a kind of bottle cap according to claim 1 is characterized in that: be connected with lid (1) or bottleneck (4) breakpoint formula on packing ring (3) circumference.

4, a kind of bottle cap according to claim 1 is characterized in that: packing ring (3) is provided with and draws mouthful (7), and is provided with easy breakpoint on its next door.

5, a kind of bottle cap according to claim 1 is characterized in that: blade (2) is arranged on the tangent line of interior garden week of bottleneck (4).
