Description

Sealing gasket for bottle

Technical Field

The application relates to the technical field of sealing gaskets, in particular to a sealing gasket for a bottle.

Background

A sealing gasket, mainly used for sealing the opening of the bottle, so that the interior of the bottle is kept sealed. The most common sealing gasket is an aluminum foil gasket which seals the opening of the bottle in a heat sealing mode and has good waterproofness and sealing performance.

For example, chinese patent with publication number CN209582377U discloses an aluminum foil sealing gasket for medicine bottles, which comprises an aluminum foil sealing gasket main body arranged between a bottle body and a bottle cap, wherein a protrusion is fixedly connected to a side wall of the aluminum foil sealing gasket main body and is easy to remove, a hot melt adhesive surface is arranged on a side wall of one end of the aluminum foil sealing gasket main body close to the bottle body, and the aluminum foil sealing gasket main body comprises an aluminum foil layer, a first functional layer, a second functional layer and a third functional layer.

Like the related art, most of the sealing gaskets of the prior art adopt the form of the sealing gasket, mainly comprise a layer of aluminum foil and a plurality of functional layers, and an easy-to-tear bulge is arranged on one side wall of the sealing gasket. However, in the actual use process, the easy-to-tear raised portion is often torn but the sealing gasket is not torn, so that the sealing gasket is difficult to tear. In view of the above problems, a sealing gasket for a bottle is proposed.

SUMMERY OF THE UTILITY MODEL

In order to improve the situation that the gasket is difficult to reveal, this application provides a gasket for bottle.

The application provides a bottle is with gasket that seals adopts following scheme:

the sealing gasket for the bottle comprises a gasket main body, wherein one side of the gasket main body is fixedly connected with an easy-to-take-off protrusion, a reinforcing belt extending along the compound position of a bottle opening is compounded in the gasket main body, and the reinforcing belt also extends from the inside of the easy-to-take-off protrusion to pass through.

Through adopting above-mentioned scheme, the strengthening band has strengthened the intensity of easily taking off arch and gasket main part for easily taking off the arch and being difficult for the tear damage, can bear bigger power, make and seal the gasket and be taken off more easily.

Optionally, the easy-open protrusion is provided with a pull-up hole, and the reinforcing strip extends from the edge of the pull-up hole.

By adopting the scheme, the fingers penetrate through the pull-convenient holes, and larger pulling force is conveniently applied to uncover the gasket main body.

Optionally, the easy-to-uncover protrusion and the gasket main body are integrally arranged, and the easy-to-uncover protrusion is bent and attached to one surface, back to the sealing side, of the gasket main body.

By adopting the scheme, the easily-uncovered bulge can be made larger, and the influence of the easily-uncovered bulge on the connection of the bottle cap is avoided.

Optionally, an arc-shaped band extending along the bottle mouth compound position is further compounded on one surface of the gasket main body, which faces away from the sealing side, and the thickness of the arc-shaped band is equal to that of the easy-to-uncover protrusion.

By adopting the scheme, when the bottle cap is covered, the bottle cap presses the arc-shaped belt and the easy-to-tear protrusion, and the arc-shaped belt and the easy-to-tear protrusion press the composite position of the gasket main body, so that the gasket can be kept sealed better.

Optionally, the gasket main body comprises a foaming layer, an aluminum foil layer, a PET layer and a heat sealing layer which are sequentially compounded, and the foaming layer is compounded with the arc-shaped belt.

By adopting the scheme, the gasket main body keeps certain strength and is convenient to uncover.

Optionally, the reinforcing tape is composited between the foam layer and the aluminum foil layer.

Through adopting above-mentioned scheme, avoid the strengthening band to influence the normal sealed of gasket main part.

Optionally, an annular groove is formed in the foaming layer, the reinforcing belt is embedded in the annular groove, and the reinforcing belt is flush with a notch of the annular groove.

By adopting the scheme, the situation that the reinforcing belt causes composite unevenness between the foaming layer and the aluminum foil layer is avoided.

Optionally, the heat-sealing layer is arranged in a circular ring shape which fits the size of the opening of the bottle.

By adopting the scheme, the material is saved, and the problem that the gasket body is difficult to uncover due to overlarge bonding area of the gasket body and the bottle is avoided.

In summary, the present application has the following beneficial effects:

1. the convex part can bear larger force, so that the sealing gasket is easier to be uncovered;

2. the protruding part is provided with a convenient-to-pull hole, so that a finger can conveniently pass through the force application to uncover the sealing gasket.

Reference numerals: 1. a gasket body; 2. the bulge is easy to uncover; 3. a reinforcing band; 4. the hole is pulled conveniently; 5. an arc-shaped band; 6. a foamed layer; 7. an aluminum foil layer; 8. a PET layer; 9. a heat seal layer; 10. and a ring groove.

Detailed Description

The present application is described in further detail below with reference to figures 1-2.

The embodiment of the application discloses a bottle is with sealing gasket, combine figure 1 and figure 2 to show, including gasket main part 1, it is protruding 2 easily to take off to be provided with in one side an organic whole of gasket main part 1, gasket main part 1 is protruding 2 easily to take off all by compound foaming layer 6 in proper order, aluminium foil layer 7, PET layer 8 is constituteed, the glue that adopts during the complex all is food level glue, in addition, still compound one deck 8PET heat-seal layer 9 on gasket main part 1, heat-seal layer 9 is compound on PET layer 8, in this embodiment, heat-seal layer 9 sets up to the ring shape of agreeing with bottle opening size, the bottleneck of bottle need not covered completely in heat-seal layer 9, the width of heat-seal layer 9 can set up the thickness that is less than the bottle promptly, only need the opening that heat-seal layer 9 encloses completely, can play sealed can.

Still compound in gasket main part 1 and easily take off arch 2 has strengthening band 3, and strengthening band 3 can adopt fibrilia cloth, plastic cloth etc. and the compound position of strengthening band 3 along the bottleneck extends, and strengthening band 3 is compound between foaming layer 6 and aluminium foil layer 7, avoids influencing the sealed effect of gasket. In order to avoid the influence of the reinforcing strip 3 on the normal combination of the foaming layer 6 and the aluminum foil layer 7, a ring groove 10 is arranged on the foaming layer 6, the reinforcing strip 3 is adhered in the ring groove 10 through glue, and the reinforcing strip 3 is flush with the notch of the ring groove 10.
