Abstract

The utility model relates to a bottle cork, comprising a bottle cork upper cover (1), a bottle cork body (2) which is cast with the upper cover (1) into a whole, a projecting thread line (3) is arranged on the bottle cork body (2), an internally concave cavity (4) is arranged at an end surface where the cork body (2) is inserted into a bottle mouth. The utility model has high plasticity, the fluid in the bottle does not flow out after the cork is squeezed in the mouth, and the utility model can be extensively used as bottle corks of various bottles for storing fluids.

Description

Bottle stopper

Technical field

The utility model relates to a kind of bottle stopper.

Background technology

Bottle stopper structure at present commonly used as shown in Figure 1, bottle cap comprise prevent bottle stopper slip into bottleneck bottle stopper loam cake 1 and with the bottle stopper body 2 of bottle stopper loam cake 1 integrated through injection molding, bottle stopper body 2 is provided with the thread 3 of protrusion.The bottle cap of this structure is because the end face of insertion bottleneck is complete plane, and plasticity is low, and a bottle inner fluid leaked easily after bottle stopper was filled in bottleneck.

The utility model content

Technical problem to be solved in the utility model provides a kind of plasticity height, bottle stopper and fills in the bottle stopper that the bottle inner fluid can not leak behind the bottleneck.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: bottle stopper, comprise the bottle stopper loam cake, with the bottle stopper body of bottle stopper loam cake integrated through injection molding, the bottle stopper body is provided with the thread of protrusion, and the end face of described bottle stopper body insertion bottleneck is provided with the cavity of indent.

Because the bottle stopper body inserts the cavity that the end face of bottleneck is provided with indent, so bottle stopper has higher plasticity inserting the bottleneck end, and the more effective bottle inner fluid that prevents leaks.

Concrete, the cavity of described indent is a cylinder.

Described cylinder axis and bottle stopper dead in line.

Described thread protrudes from bottle stopper body 0.01～0.05cm.The bottle stopper thread protrudes from the bottle stopper body and is generally 0.1cm at present, because it is excessive that thread protrudes from the distance of bottle stopper body, easy deformation caused a bottle inner fluid to leak easily when thread was filled in bottle, thread is protruded from bottle stopper body 0.01～0.05cm, deformation when filling in bottle, thread takes place hardly, can not cause bottle inner fluid to leak, and bottle stopper have skidproof effect.

To sum up, the beneficial effects of the utility model are: because the bottle stopper body inserts the cavity that the end face of bottleneck is provided with indent, bottle stopper has good plasticity after filling in bottleneck, and the bottle inner fluid can not leak.

The specific embodiment

As Fig. 2, shown in Figure 3, bottle stopper, comprise bottle stopper loam cake 1, with the bottle stopper body 2 of bottle stopper loam cake 1 integrated through injection molding, the side that bottle stopper body 2 contacts with bottleneck is provided with the thread 3 of protrusion, and thread 3 protrudes from bottle stopper body 0.02cm, the end face that bottle stopper body 2 inserts bottleneck is provided with the circular cylindrical cavity 4 of indent, cylindrical cavity body axis and bottle stopper dead in line are provided with reverse hook teeth 5 in the side that the bottle stopper body does not contact with bottleneck, and bottle stopper is filled in the back opener and can be acted on reverse hook teeth 5 bottle stopper is extracted.As Fig. 4, shown in Figure 5, according to using needs, bottle stopper loam cake of the present utility model can be set to circle or equilateral polygon (present embodiment is an octagon).

Claims

1. bottle stopper comprises bottle stopper loam cake (1), and with the bottle stopper body (2) of bottle stopper loam cake (1) integrated through injection molding, bottle stopper body (2) is provided with the thread (3) of protrusion, it is characterized in that, the end face of described bottle stopper body (2) insertion bottleneck is provided with the cavity (4) of indent.

2. bottle stopper according to claim 1 is characterized in that, the cavity of described indent (4) is a cylinder.

3. bottle stopper according to claim 2 is characterized in that, described cylinder axis and bottle stopper dead in line.

4. according to any described bottle stopper of claim 1 to 3, it is characterized in that described thread (3) protrudes from bottle stopper body (2) 0.01～0.05cm.
