Description

Bottle cap with sealing performance

Technical Field

The utility model relates to the technical field of bottle cap sealing, in particular to a bottle cap with sealing performance.

Background

The existing medical bottle cap has the strict sealing requirement, and a sealing cap is additionally arranged in the common bottle cap. However, the sealing cover in the prior art is designed as an arc ring, and the sealing effect of the arc ring varies due to different materials, sizes and the like. Even during the opening process of the outer cover, the outer cover can be brought out together, so that the opening of the container is completely exposed, and the original sealing purpose is lost.

Therefore, a new bottle cap with better sealing performance is needed.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art, provides a bottle cap with sealing performance, and solves the problem that the existing sealing body is poor in sealing effect and better in sealing effect. But also can avoid the defect that the inner cover is taken out by the outer cover to a certain extent.

The purpose of the utility model is achieved by the following technical measures: the utility model provides a bottle lid with sealing performance, includes enclosing cover and inner cup, the enclosing cover is cylindrical, the inside cavity of enclosing cover, the one end of enclosing cover is the blind end, the other end of enclosing cover is the open end, the blind end of enclosing cover in the inner cup embedding enclosing cover and laminating enclosing cover, the inner cup is including flat lid and seal, flat lid is the platykurtic, flat lid level sets up, the seal sets up on vertical one side of flat lid be provided with first gasket and second gasket on the lateral wall of seal, first gasket sets up the vertical one end at the seal, the second gasket sets up the vertical other end at the seal.

Further, the first seal fin is annular as a whole, and a vertical cross section of the first seal fin is arc-shaped.

Further, the whole second sealing piece is annular, and the vertical section of the second sealing piece is arc-shaped.

Furthermore, the arc-shaped tail end of the first sealing piece wraps the arc-shaped tail end of the second sealing piece between the first sealing piece and the outer side wall of the sealing body.

Compared with the prior art, the utility model has the beneficial effects that: the sealing body is additionally provided with double sealing pieces (a first sealing piece and a second sealing piece), so that the sealing effect is better. And the defect that the inner cover is brought out by the outer cover can be avoided to a certain extent through the arrangement of the first sealing sheet and the second sealing sheet.

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Drawings

FIG. 1 is a schematic structural view of the present invention.

Fig. 2 is a schematic view of the structure of the inner lid.

Fig. 3 is a sectional view of the inner lid.

The sealing structure comprises a flat cover body 1, a sealing body 2, a first sealing sheet 3, a second sealing sheet 4 and an outer cover 5.

Detailed Description

As shown in fig. 1 to 3, a bottle cap with sealing performance, includes enclosing cover 5 and inner cup, enclosing cover 5 is cylindrical, the inside cavity of enclosing cover 5, the one end of enclosing cover 5 is the blind end, the other end of enclosing cover 5 is the open end, the blind end of inner cup embedding enclosing cover 5 in and laminating enclosing cover 5, the inner cup is including flat lid 1 and seal 2, flat lid 1 is the platykurtic, flat lid 1 level sets up, seal 2 sets up on the vertical one side of flat lid 1 be provided with first gasket 3 and second gasket 4 on the lateral wall of seal 2, first gasket 3 sets up the vertical one end at seal 2, second gasket 4 sets up the vertical other end at seal 2. The sealing body 2 is additionally provided with a double sealing sheet, specifically a first sealing sheet 3 and a second sealing sheet 4, so that the sealing effect is better. The sealing body 2 is in an arc-shaped design in the prior art, the sealing performance of the lower part of the sealing body 2 can be improved by adding the first sealing sheet 3 outside the sealing body, and the sealing performance of the upper part of the sealing body 2 can be improved by adding the second sealing sheet 4 outside the sealing body.

The whole first sealing piece 3 is annular, and the vertical section of the first sealing piece 3 is arc-shaped. The ring shape of the first seal fin 3 is connected to the entire outer circumferential edge of the seal body 2, thereby forming a continuous 360-degree increase seal. The arc shape of the first sealing fin 3 facilitates the insertion of the sealing body 2 into the container while increasing the sealing effect of the sealing body 2.

The second seal piece 4 is annular as a whole, and the vertical section of the second seal piece 4 is arc-shaped. The ring shape of the second seal piece 4 is connected with the outer edge of the circumference of the seal body 2 to form continuous 360-degree increasing seal. The arc shape of the second sealing fin 4 facilitates the insertion of the sealing body 2 into the container and increases the sealing effect of the sealing body 2.

The arc-shaped tail end of the first sealing piece 3 wraps the arc-shaped tail end of the second sealing piece 4 between the first sealing piece 3 and the outer side wall of the sealing body 2. This design facilitates the simultaneous approach of the first seal fin 3 and the second seal fin 4 to the outer wall of the seal body 2 when the seal body 2 is inserted into the container. The circular arc-shaped end of the second seal fin 4 refers to the opposite end connected to the seal body 2. The end of the first seal piece 3 in the shape of a circular arc also refers to the opposite end connected to the seal body 2.
