Abstract

The utility model belongs to the field of product packaging and particularly relates to a bottle cap. The bottle cap comprises a cover plate and a coaming, wherein the lower surface of the cover plate is provided with an inner plug ring; a plurality of supporting ribs are arranged at the connection between the inner wall of the inner plug ring and the cover plate; and one end of each supporting rib is connected with the inner wall of the inner plug ring, and the other end of each supporting rib is connected with the cover plate. The supporting ribs are uniformly distributed along the inner wall of the inner plug ring. The supporting ribs arranged on the inner plug ring of the bottle cap are used for enhancing the strength of the inner plug ring on the bottle cap, preventing the situation that the mouth of a package bottle cannot be sealed because the inner plug ring deforms under the action of an external force, and meanwhile improving the overall strength of the bottle cap, and thus, a consumer is facilitated to open the bottle cap. The bottle cap is suitable for being popularized and applied in the field of package and particularly in the package bottle packaging industry.

Description

A kind of bottle cap

Technical field

The utility model belongs to field of product packaging, is specifically related to a kind of bottle cap.

Background technology

Along with socioeconomic continuous development, it is the important component part of commodity that packing is progressively promoted by the commodity subordinate position, and packaging industry has become one of staple product of Chinese national economy.Because the continuous lifting of plastics industry status in national economy, the mould of plastics development very rapidly.According to statistics, China surpasses 30,000,000,000 in the annual needed Packaging Bottle of industries such as food, beverage, and each Packaging Bottle all needs bottle cap that it is sealed.Because the Packaging Bottle enormous amount of using, the manufacturer of these Packaging Bottle and bottle cap is numerous, and its raw-material quality is difference to some extent, and the bottle cap quality of production is uneven; Some manufacturer particularly, in order to practice thrift cost, the integral thickness of its bottle cap is thinner; During the bottle cap of customer on opening Packaging Bottle, be distorted after bottle cap is stressed, cause the article in the Packaging Bottle to leak; When the bottle cap after the distortion reuses, can't seal, people's life is brought inconvenience Packaging Bottle.

The utility model content

The utility model technical matters to be solved is: the bottle cap that a kind of intensity is higher, be convenient to open is provided.

The utility model solves the technical scheme that its technical matters adopted: a kind of bottle cap; Comprise cover plate and coaming plate; The lower surface of said cover plate is provided with interior plug ring; Plug ring inwall and cover plate junction are provided with a plurality of brace rods in said, and said each brace rod one end is connected with interior plug ring inwall, and the other end is connected with cover plate.

Further be that said a plurality of brace rods are along interior plug ring inner wall even distribution.

The beneficial effect of the utility model is: the brace rod that in bottle cap, is provided with on the plug ring; The intensity of plug ring in having strengthened on the bottle cap; Plug ring deforms under external force and can't seal the Packaging Bottle position of bottleneck in preventing; Simultaneously, this brace rod has been strengthened the bulk strength of bottle cap, helps the customer and opens bottle cap.

Description of drawings

Mark among the figure: cover plate 1, reinforced rib 2, interior plug ring 3, coaming plate 4.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further explanation.

The utility model belongs to field of product packaging, is specifically related to a kind of bottle cap.This bottle cap comprises cover plate 1 and coaming plate 4, and the lower surface of said cover plate 1 is provided with interior plug ring 3, a plurality of brace rods 2 of said interior plug ring 3 inwalls and cover plate 1 junction, and said each brace rod 2 one end are connected with interior plug ring 3 inwalls, and the other end is connected with cover plate 1.

Plug ring 3 is used for the sealing to the Packaging Bottle bottleneck in said, and when tightening bottle cap, interior plug ring 3 extends in the packing bottle along Packaging Bottle bottleneck inwall, and interior plug ring 3 and Packaging Bottle bottleneck interference fit stop the article in the Packaging Bottle to leak.Plug ring 3 is arranged on the lower surface of cover plate 1 in said, and for the intensity of plug ring 3 in increasing, plug ring 3 deforms under external force and can't seal Packaging Bottle in preventing, said interior plug ring 3 is provided with a plurality of brace rods 2 with cover plate 1 junction.If but these brace rods 2 are arranged on interior plug ring 3 outer walls and cover plate 1 junction; Packaging Bottle bottleneck end face can't with cover plate 1 lower surface contact seal; Influence the sealing function of bottle cap; Therefore plug ring 3 inwalls and cover plate 1 junction in said a plurality of brace rods 2 are arranged on, said each brace rod 2 one end are connected with interior plug ring 3 inwalls, and the other end is connected with cover plate 1.These a plurality of brace rods 2 have increased the intensity of cover plate 1, have guaranteed the stability of bottle cap, have increased the leak tightness of bottle cap, are convenient to open bottle cap simultaneously.

Because the Packaging Bottle bottleneck be circular, when turning bottle cap, its stress point is positioned at the optional position of coaming plate 4, when bottle cap receives distortion power, for all can the be supported support of muscle 2 of each point on the plug ring 3 in guaranteeing, interior plug ring 3 inner wall even distributions in said a plurality of brace rods 2 edges.

Claims

1. bottle cap; Comprise cover plate (1) and coaming plate (4); The lower surface of said cover plate (1) is provided with interior plug ring (3); It is characterized in that: plug ring (3) inwall and cover plate (1) junction are provided with a plurality of brace rods (2) in said, and said each brace rod (2) one end are connected with interior plug ring (3) inwall, and the other end is connected with cover plate (1).

2. bottle cap as claimed in claim 1 is characterized in that: said a plurality of brace rods (2) are along interior plug ring (3) inner wall even distribution.
