Description

A kind of cover-lifting double flexible pipes

Technical field

The invention belongs to packing of product container technical field, particularly a kind of cover-lifting double flexible pipes.

Background technology

The flexible packaging of the products such as common cosmetics, medicine, toothpaste, medical ointment, adopts squash type single tube structure more.Some cosmetics, as ultra light sun block lotion, lipstick and hair dye etc., often requires plurality of kinds of contents thing to be in harmonious proportion in proportion use, but still adopts now single tube packaged form, not only increases packing cost, and uses, carries and have inconvenience more.

The two-tube container of squash type of existing market, adopts screw top more, fixing need to the realization by complex-shaped a plurality of parts of installation of its inner and outer pipe, complex structure; And how the two-tube container of this class is not with control cock, the content in the easy backflow pollution pipe of content squeezing out during use, and the content in container is squeezed also easily excessive.

Summary of the invention

For the above-mentioned defect of avoiding existing flexible pipe container to exist, the present invention proposes a kind of cover-lifting double flexible pipes, it adopts flip, inside arranges the content liquid outlet channel of inner tube and the content liquid outlet channel of outer tube, two liquid outlet channels are all established control cock, content in the content backflow pollution pipe that can avoid squeezing out, and avoid the content in pipe to be squeezed excessive.

Cover-lifting double flexible pipes of the present invention, comprising:

One outer tube, its tube head arranges the first ozzle and the second ozzle;

One inner tube, its tube head arranges the external pipe connection mouth that interior ozzle and sidewall have import, between interior ozzle and external pipe connection mouth, has inserting groove, and this inner tube is positioned at described outer tube, and this interior ozzle and this external pipe connection mouth are plugged into respectively in described the first ozzle and the second ozzle;

One valve block assembly, comprise strut bar and from strut bar both sides extended two valve blocks, strut bar is plugged in the inserting groove of tube head of described inner tube, these two valve blocks cover respectively described interior ozzle and external pipe connection mouth; And,

One flip, comprise top cover and the cage with two chock plugs, the end face of cage is established the first liquid outlet and the second liquid outlet, under first and second liquid outlet, extending respectively the first adapter and second takes over, first and second is taken over periphery and establishes connection pipe, cage is installed on the tube head of described outer tube by this connection pipe, first and second take over insert respectively first and second ozzle of described outer tube suitable for reading in.

Wherein, the tube head outer wall of described outer tube is established outer shroud rib, and in the oral area of described cage, along establishing interior ring rib, this interior ring rib is connected to the lower edge of this outer shroud rib.

The liquid outlet channel of described outer tube by the import of described external pipe connection mouth side, the inner chamber of the inner chamber of described external pipe connection mouth, described the second ozzle, described second takes over and described the second liquid outlet forms.

Cover-lifting double flexible pipes of the present invention by have two ozzles outer tube, there is external pipe connection mouth and flip combination that interior ozzle and side have import, the inner liquid outlet channel of inner tube and the liquid outlet channel of outer tube of forming, two liquid outlet channels are controlled by control cock, content in the content backflow pollution pipe of effectively avoiding squeezing out has avoided the content in pipe to be squeezed excessive simultaneously.

This cover-lifting double flexible pipes assembling, easy to use, applicable two kinds of pro rata packings of content, are widely used in the flexible packaging of the products such as cosmetics, medicine, toothpaste, medical ointment.
