Description

A kind of bottle of dual bottle cap sealing

Technical field

The utility model relates to bottle seal fields, more particularly to a kind of bottle of dual bottle cap sealing.

Background technique

Existing bottle is to unify bottle cap in the upper end screw-button of body, in order to improve the close of body and bottle cap Feng Xing, bottle cap are equipped with the gasket of annular in outer edge.When for when saving some extremely hygroscopic industrial chemicals, taking repeatedly Work raw material is easy to be mixed into air；Even if each bottle cap all screws closely, but it can be volatilized using industrial chemicals long afterwards and pollute bottle cap With the junction of body, gasket is eroded before this, and then is diffused on the outside of body, this is also why many bottles are using long afterwards The dirty reason of bottle mouth position crystallization, body.Existing some bottles are made into inside and outside two sets of bottle caps, but operation causes to take in this way Journey becomes trouble.

Utility model content

The purpose of this utility model is to provide a kind of good seal performance and take the bottle of convenient dual bottle cap sealing.

Technical solution adopted in the utility model is:

A kind of bottle of dual bottle cap sealing, including body and the first bottle cap, body is interior to be equipped with the second bottle cap, the second bottle cap Including connection ring and the partition being located on the inside of connection ring, the outside of connection ring and the inner wall of body are connected, and partition is elastic rubber, The middle position of partition has perforation, and the downside of the first bottle cap is equipped with the column that may pass through perforation, and column is truncated cone-shaped, in nature The diameter of perforation under state is between the maximum diameter and minimum diameter of column.

As an improvement of the above scheme, perforation is located at the middle position of partition, and column is located at the middle position of the first bottle cap.

As an improvement of the above scheme, the taper of column is 1:12~1:16.

As an improvement of the above scheme, the inside of connection ring is equipped with groove, and the outer edge of partition is in groove, connection ring There is sealant with the junction of partition.

As an improvement of the above scheme, several notches are evenly provided on the upside of connection ring.

As an improvement of the above scheme, between the inside and connection ring of body and between the outside and the first bottle cap of body It is to be threadedly coupled.

The utility model has the beneficial effects that the first bottle cap forms first of seal line after buckling, and the second bottle cap and vertical The combination of column forms second line of seal, and central post insertion perforation rear bulkhead can clamp fitting column by flexible deformation Side, the combination of two seals line improve the sealing effect of bottle；And unscrewing bottle cap can open simultaneously twice when in use Seal line conveniently takes the industrial chemicals in bottle.

Detailed description of the invention

The utility model is described in further detail with reference to the accompanying drawing:

Fig. 1 is the schematic diagram that bottle fastens the first bottle cap；

Fig. 2 is the schematic diagram under the independent state of bottle.

Specific embodiment

Referring to Figures 1 and 2, the utility model is a kind of bottle of dual bottle cap sealing, including body 1 and the first bottle cap 2, The second bottle cap is equipped in body 1, the second bottle cap includes connection ring 3 and the partition 4 for being located at 3 inside of connection ring, the outside of connection ring 3 It is connect with the inner wall of body 1, partition 4 is elastic rubber, and the middle position of partition 4 has perforation, and the downside of the first bottle cap 2 is equipped with May pass through the column 5 of perforation, column 5 is truncated cone-shaped, the diameter of perforation in its natural state between column 5 maximum gauge and Between minimum diameter, the alignment insertion of column 5 is convenient.Perforation is located at the middle position of partition 4, and column 5 is located in the first bottle cap 2 Between position.It is to be threadedly coupled between the inside of the body 1 and connection ring 3 and outside of body 1 and the first bottle cap 2.

First bottle cap 2 forms first of seal line after buckling, the combination of the second bottle cap and column 5 forms second sealing Line, the insertion perforation rear bulkhead 4 of central post 5 can clamp the side of fitting column 5, the group of two seals line by flexible deformation Close the sealing effect for improving bottle；And unscrewing bottle cap can open simultaneously two seals line when in use, conveniently take bottle Interior industrial chemicals.

Column 5 can be cylinder, and the diameter of column 5 is greater than the diameter of perforation at this time.But in view of the manufacture of product misses Difference, the complexity for screwing alignment can fluctuate, and as preferred embodiment, taper is 1:12~1:16；In this cone The side of column 5 under degree is basically perpendicular to the inner plane of bottle cap, and the first bottle cap 2, which screws rear column 5, can effectively strut perforation, Then it is bonded with partition 4 closely.

As preferred embodiment, the inside of connection ring 3 is equipped with groove, and the outer edge of partition 4 is in groove, connection The junction of ring 3 and partition 4 has sealant.This design is the fixed design of partition 4, is in disc-shaped before the non-aperture of partition 4.

As preferred embodiment, the upside of connection ring 3 is evenly provided with several notches, finds force convenient for finger Point screws connection ring 3.

Certainly, the design creation is not limited to above embodiment, and the combination of the various embodiments described above different characteristic can also To reach good effect.Those skilled in the art can also make without departing from the spirit of the present invention It is all included in the scope defined by the claims of the present application with deformation or replacement, these equivalent variation or replacement.
