Description

Vacuum valve coupled to plastic bag The present invention relates to a vacuum valve coupled to a vinyl bag. Specifically, the invention relates to a vacuum valve coupled to an open end of a vinyl bag, wherein the vinyl is fitted and fixed while the two bodies are separated, and after the two bodies are combined, air is sucked in from one side to create a vacuum inside the vinyl. Generally, to store food at home, methods are used to store food hygienically by using a separate container or placing it in a disposable plastic bag and sealing the opening. However, as described above, if air enters the inside of a container or plastic bag during the food storage process, a problem arises in which the food spoils quickly due to moisture or microorganisms contained within the air. To resolve these problems, a device has been devised that removes air from inside a plastic bag and seals the opening by heat, but such a device inevitably increases in size and is burdensome to keep on hand for use in every household. In this regard, Registered Utility Model Publication No. 20-0427792 describes a valve for a compression vinyl bag. The above technology relates to a valve for a compressed vinyl bag, and in particular to a valve for a compressed vinyl bag that is capable of more effectively blocking air from entering the compressed vinyl bag by releasing air. The valve (1) for such a compression vinyl pack comprises a main body (10) which is coupled to the inner side of the vinyl pack and has a coupling part (13) for coupling a blocking member (30) in the central part, and in which the coupling part (13) is coupled to the main body (10) through a plurality of ribs (14) and an air passage is formed in the coupling part (13); a cover (20) which is coupled to the main body (10) with the vinyl pack in between and has a coupling hole (22) for coupling a blocking member (30) in the central part and has a plurality of holes (23) for discharging air on the upper side; and a blocking member (30) which is coupled to the coupling part (13) and the coupling hole (22) so as to be movable upward and downward, and is coupled to the coupling hole (22) through an elastic member (40) so as to receive downward force by the elastic member (40) to block the flow of air. Accordingly, by using an elastic member inside the valve for a compression vinyl bag to enhance the sealing force between the blocking member and the protrusion, it is possible to implement a valve for a compression vinyl bag that can maintain a vacuum state inside the vinyl bag for a long period of time or prevent air from entering the interior of the vinyl bag even when an external impact is applied to the vinyl bag. In addition, Registered Utility Model Publication No. 20-0340852 describes a cap for vacuum packaging of a plastic bag. The above technology relates to a vacuum packaging cap for a plastic bag, and more specifically, to a vacuum packaging cap for a plastic bag that maintains a vacuum state while food is placed in a disposable plastic bag commonly used. The structure comprises an inner tube body that is hollow inside, open vertically, and has a spiral formed on its outer surface; and an outer cap to which the inner tube body is connected on its inner surface, and which is equipped with an opening/closing valve for injecting and removing air on one side of its closed upper surface. Accordingly, this not only has the effect of keeping food fresh for a longer period of time, but also has the effect of making it easier to manufacture due to its simple structure. FIG. 1 shows a vacuum valve coupled to a vinyl bag according to the present invention. Figure 2 shows the vacuum valve of Figure 1 separated. Figure 3 shows an example of the vacuum valve of Figure 1 being coupled to vinyl. FIG. 4 shows the lower surface of the upper body of a vacuum valve coupled to a vinyl bag according to the present invention.
