Abstract

The utility model discloses a container with an anti-leakage one-way valve; a gas-liquid separation filter device is arranged between an air inlet of the one-way valve and a containing article; liquid and solid in the container are separated from the air inlet of the one-way valve through a waterproof ventilating film with a larger area on the gas-liquid separation filter device; and the aims that exhausting and non-return and liquid and/or solid powder in the container can be prevented from leaking through large amount of gas can be achieved simultaneously. The container with the anti-leakage one-way valve can be used for packing and storing substances contained with powder and liquid, which can produce gas and need oxygen barrier, such as the ground coffee, powder feed and pickled vegetable retaining probiotics and other food needing continuous fermentation.

Description

Anti-leak check valve container
Affiliated technical field
The utility model relates to a kind of container, especially relates to a kind of exhaust non-return and the check valve container of no leak liquid and solid.
Background technology
At present, known check valve container is provided with check valve by leakproof tank and constitutes, and check valve shell and wall of container are tightly connected, admission port connection container inside, exhausr port connection container outside.When internal tank air pressure was higher than the outside, check valve was opened, and the unnecessary gas in the amount discharge container is avoided being out of shape even damage behind the container pressurized.When external container pressure was higher than inside, closed check valve stoped in the air admission container, caused contents rotten, corrupt.This container is when holding these class bulky grain article of coffee bean, both can get rid of the carbon dioxide that coffee bean produces, can stop external oxygen to be poured in down a chimney again and influence fragrance and taste, very effective, but, if the contents of this container comprise liquid or during less than the pressed powder of check valve induction opening, liquid and can leak stained check valve and container from check valve less than the pressed powder of check valve induction opening.
Summary of the invention
In order to overcome the deficiency that existing check valve container can not prevent that liquid and pressed powder from leaking, the utility model provides a kind of check valve container, this check valve container can not only unidirectional exhaust, and can prevent that liquid in the contents and pressed powder from by check valve, leaking into external container.
The technical scheme that its technical matters that solves the utility model adopts is: leakproof tank is provided with check valve, check valve shell and wall of container are tightly connected, and the admission port of check valve is communicated with internal tank, it is characterized in that: a gas-liquid separation filtering installation is set between check valve and contents, check valve inlet and contents are isolated in adjacent chamber, and this gas-liquid separation filtering installation comprises a waterproof ventilated membrane, and its area that contacts two adjacent chamber portions simultaneously is greater than the check valve inlet area.The waterproof ventilated membrane of gas-liquid separation filtering installation, the small filter opening that gathers allows the individual molecule of gas to pass through, and intercepts agglomerating liquid of any molecule and solia particle.Gas unnecessary in the container can see through the part that waterproof ventilated membrane contacts two adjacent chambers simultaneously, in time enters check valve inlet place chamber from contents place chamber, again outside check valve is discharged into container.And the most small drop and pressed powder also can be intercepted at contents place chamber by the gas-liquid separation filtering installation, can't enter check valve inlet place chamber, through the check valve discharging, reach the liquid and the pressed powder that prevent in the contents and pass through check valve, leak into the purpose of external container.
The beneficial effects of the utility model are to prevent any liquid and/or pulverulent solids content leaks in the unidirectional exhaust of container, stained container and check valve, the normal keying that keeps the clean and tidy and check valve of container prolongs guaranteeing the quality the time of contents, simple in structure, dependable performance.

1. check valves among the figure, 2. waterproof ventilated membrane, 3. packing seal, 4. negative thread, 5. outside thread, 6. container cover, 7. container cavity, 8. air extractor vent, 9. contents, 10. burr, 11. flanges.
The specific embodiment
In Fig. 1, first embodiment shown in Figure 2, the container cavity 7 that container cover 6 that high molecular polymer constitutes and glass constitute is connected with outside thread 5 by the negative thread 4 that cooperatively interacts.Container cover 6 is provided with air extractor vent 8, and check valve 1 is arranged on the air extractor vent position of container cover 6.Check valve 1 is selected button-shaped coffee bag one-way exhaust valve for use, and the air inlet microcephaly sinks in the air extractor vent 8 of container cover in container.The anchor ring that contacts of ultrasonic welding check valve 1 edge and container cover 6 outer walls the wall of check valve 1 shell and container cover 6 is tightly connected, and the admission port of check valve 1 is communicated with internal tank.The gas-liquid separation filtering installation is made of the Gask-O-Seal 3 that waterproof ventilated membrane 2 and middle part have through hole.The shape of waterproof ventilated membrane 2 matches with packing seal 3, container cover 6 bottoms, container chamber 7 opening outer rims.When screwing container cover 6, waterproof ventilated membrane 2 and packing seal 3 are compressed between container cavity 7 openings and container cover 6 bottoms, check valve 1 admission port and contents 9 are isolated in adjacent chamber, constitute a gas-liquid separation filtering installation, and this gas-liquid separation filtering installation comprises a waterproof ventilated membrane, and its area that contacts two adjacent chamber portions simultaneously is greater than check valve 1 admission port area.Waterproof ventilated membrane 2 is selected microporous teflon membran (ePTFE) for use, the micropore of dense distribution only allows single gas molecule to see through on the film, enter check valve 1 discharging, and intercept any molecule agglomerating minimum drop and solid, it is constrained in the chamber of waterproof ventilated membrane below 2, can't arrive check valve 1 admission port, stained check valve 1, leak into external container.
In Fig. 3, second embodiment shown in Figure 4, container cover 6 is preferably polyethylene for having the sheet high molecular polymer of air extractor vent 8.Check valve 1 is arranged on container cover 6 outer walls, selects the square one-way exhaust valve of self-adhering type for use, covers the air extractor vent position of container cover 6.Outer wall around the shell of the square one-way exhaust valve air inlet of self-adhering type side and the container cover air extractor vent 8 bonds together, and formation is tightly connected, and the admission port of check valve 1 is communicated with internal tank.Container chamber 7 is made of the high molecular polymer of cup-shaped, is preferably polyethylene, and opening is provided with flange 11.Waterproof ventilated membrane 2 is arranged between the flange 11 of container cover 6 and container cavity 7 openings, and its edge is tightly connected with the two simultaneously.Connection mode is preferably heat fusion and connects.Waterproof ventilated membrane 2 forms a laminar separate space with container cover 6, and check valve 1 admission port and contents 9 are isolated in adjacent chamber, constitutes the gas-liquid separation filtering installation.Waterproof ventilated membrane 2 is selected spunbonded type alkene (Spunbonded Olefin) for use, and its area that contacts two adjacent chamber portions simultaneously is bigger 10 times than check valve 1 admission port, can guarantee in time seeing through of a large amount of gases, and liquid barrier and solid.Waterproof ventilated membrane 2 is provided with a plurality of well-distributed spherical crown shape burrs 10 near container cover inwall one sides, and burr 10 forms by hot pressing, can avoid waterproof ventilated membrane 2 to be fitted in the inwall of container cover, influences the whole drainage rate of gas.
