Vacuum bag manufacturing method and product of the same

Abstract

The invention discloses a vacuum bag manufacturing method, and further discloses a product obtained by adopting the method. The vacuum bag manufacturing method and the product of the vacuum bag comprise a bag body and a vent valve. The vent valve comprises a valve seat, a valve cover and a cone-shaped soft plug. The method is easy in manufacturing procedure, easy to realize, and capable of being used for quickly manufacturing the vacuum bag product which is good in sealing effect and convenient to use. The vacuum bag product is ingenious and reasonable in structural design. The cone-shaped soft plug and an opening of an accommodating cavity are matched for sealing air, an operator just needs to cover the valve cover to ensure that the cone-shaped soft plug is tightly attached on the opening, and accordingly sealing effects are achieved. The valve cover is plugged out to ensure that air freely enters and leaves the bag body to bring convenience to air pumping and use. Furthermore, a flange is arranged on the opening to further strengthen sealing effects, and articles can be beneficially stored for a long period. A bag opening can be quickly opened or sealed through concave-convex seals. The vacuum bag manufacturing method and the product of the vacuum bag are convenient to use and simple and easy to operate, bring great convenience to the steps of taking and putting the articles and life of people, and facilitate wide promotion and applications.

Description

technical field [0001] The invention relates to the technical field of vacuum bags, in particular to a method for making a vacuum bag and its products. Background technique [0002] Vacuum bags can be used to store various clothing and household items, such as clothing and quilt covers, etc. It isolates the stored items from the outside world by extracting the air, which not only prevents mildew, but also keeps the stored clothes and quilt covers with you. With the extraction of air, the volume is reduced, and finally compressed, which is convenient for people to carry and store. The structure of the vacuum bag is usually provided with an air valve for pumping and releasing air on the bag body, and the air pump is connected through the air valve to extract the air in the vacuum bag. After the air is drawn out, the air valve is sealed and closed, which is convenient It prevents air from entering, and if you need to release air, you only need to open the air valve. [0003] ...

AI Technical Summary

Problems solved by technology

[0003] At present, the air valves of vacuum bags on the market are mostly sealed by the cooperation of plugs and plug holes, but this structure is not tightly sealed, and it is often prone to failure, resulting in air leakage. Moreover, the air in the sealed state will gradually flow from the plug and The vacuum bag enters between the plug holes, which is not conducive to long-term use; in addition, there is a kind of air valve that is sealed by screwing. Compared with the plug type air valve, its sealing effect is better, but this type of air valve It needs to be rotated when sealing or opening, which is time-consuming and laborious, and it is also inconvenient to use

Moreover, it is not very convenient to open the vacuum bag, which brings inconvenience to people's use.
