Description

Vacuum preservation container variable space}

The present invention relates to a vacuum storage container capable of varying the storage space, and more particularly, by varying the storage space according to the amount of the storage, vacuum storage container that can be changed in the storage space to simplify the flow of food It is about.

Generally, a vacuum storage container is a container in which a packing is attached to a lid to improve the sealing property between the lid and the container body. Since the food vacuum container can prevent the food from leaking and spreading the smell, it is widely used when food is to be transported to the outside, such as a lunch box, or when food is stored for a long time. In particular, since various kinds of foods are stored in the refrigerator, the smell of each food causes odors or deteriorates the flavor of each food. Therefore, the food vacuum container is also used as a container for a refrigerator. have.

As shown in FIG. 4, the vacuum container pre- filed by the inventor among the vacuum storage containers has a normal container body 101 and a lid 103, and the lid 103 has air for forming a vacuum of the container. Outflow valve 120 is provided.

The air inlet valve 120 has a hemispherical cover 121, a push button 125 formed with a push rod 126 fixed downwardly through the cover 121 and protruded downward in the center region, and a lid 121. Hermetically coupled to (103) and the tubular hermetic holding tube 130, the air outlet hole 134 is formed, and the blocking plate 127 for opening and closing the air outlet hole 134 in accordance with the push of the push button 125 Include.

In the center region of the hemispherical cover 121, a button receiving portion 122 is formed to accommodate the push button 125, and the push rod 126 of the push button 125 is formed at the bottom of the button receiving portion 122. The through-hole through-hole 123 is formed and the air through-hole 124 for the passage of air is formed on the outside of the through-hole through (123).

The blocking plate 127 is formed of an elastic material such as rubber, and a pocket-shaped inserting portion 129 into which the push bar 126 of the push button 125 is inserted is formed in the center region of the blocking plate 127. .

The airtight holding tube 130 is formed of soft silicon and is expanded to the lid 103 and the enlarged diameter portion 131 coupled to surround the button receiving portion 122 inside the hemispherical cover 121. It has a neck portion 132 and a diaphragm 133 formed between the enlarged diameter portion 131 and the shaft diameter portion 132. The diaphragm 133 has an insertion part 129 through which the insertion part 129 passes and air flows in and out.

On the other hand, the lid 103 to which the air inlet and outlet valve 120 is fixed, is formed with a valve receiving portion 151 in which the air inlet and outlet valve 120 is accommodated. The bottom surface of the valve accommodating part 151 passes through a circular receiving groove 153 for accommodating the shaft diameter part 132 of the hermetic holding tube and the insertion part through-hole 134 to support the insertion part 129 region. Support ribs 155 are formed.

When storing food in such a container to discharge the air in the container using a pump (not shown) to maintain the vacuum in the container. When the air is sucked into the push button 125 area of the air inlet valve 120, the edge of the blocking plate 127 is spaced apart from the insertion hole 134 by the suction force of the pump. Air in the vessel is leaked out. On the other hand, when the food is withdrawn by pressing the push button 125, the insertion portion of the blocking plate 127 is moved downward and the edge is spaced apart from the insertion hole through hole 134, the air is discharged.

By the way, when the food vacuum container is formed in a large amount, when the food is stored in a large amount in the container, the amount of air to be discharged is small to form a vacuum. The amount of air that has to be introduced into the vessel for de-vacuation increases, and the amount of air that has to be evacuated during vacuum formation increases. Accordingly, there is a disadvantage in that a lot of force and time are consumed in forming and releasing the vacuum when the container is not moved. In addition, when the container is deeply formed, there is a disadvantage that it is difficult to withdraw the food when the amount of food is small.

Accordingly, an object of the present invention is to provide a vacuum storage container capable of changing the storage space to facilitate the vacuum formation and release, and at the same time to withdraw the food.

Here, the container body is formed with an air through hole formed through the container body, and a coupler formed with a male thread projecting along the circumferential direction of the air through hole; The intake valve preferably has a blocking plate for opening and closing the air passage hole, and a stopper for forming a female screw thread from which a partial region is removed and coupled to the coupler.

Hereinafter, with reference to the accompanying drawings will be described in detail the present invention.

As shown in FIG. 1, the food vacuum container includes a normal container body 2 and a lid 3 covering an opening of the container body 2.

The lid 3 is provided with an air inlet valve 20 for vacuum forming and releasing the vacuum of the container body 2, and when a separate pump is sucked into the air inlet valve 20, the container body 2 is provided. The air inside can be discharged to the outside.

In the container body 2, a moving plate 15 arranged in the longitudinal direction of the container body 2 is mounted. The moving plate 15 is provided with a receiving groove 16 along the circumferential direction on a surface in contact with the inner wall of the container body 2, the inside of the receiving groove 16 to maintain airtightness with the inner wall of the container body (2) In order to insert the airtight packing 17 formed of silicon. The moving plate 15 may move toward the lid 3 according to whether the suction valve 30 is opened or closed when air is discharged from the container through the air inlet valve 20.

Meanwhile, the bottom surface of the container body 2 is raised toward the inside of the container, and a suction valve 30 for introducing air into the container body 2 is provided in the center area of the bottom surface.

For the installation of such a suction valve 30, as shown in Figure 2, the bottom surface of the container body 2 is a cylindrical coupling hole 9 protruding toward the outside of the container body 2 from the plate surface A male acid is formed in the outer peripheral surface of the coupler 9. Inside the coupler (9) is formed a fixing hole (7) through which the blocking plate 31 to be described later penetrates the bottom surface of the container body (2), a plurality of along the circumferential direction of the fixing hole (7) An air passage hole 5 is formed.

On the other hand, the intake valve 30 includes a blocking plate 31 for opening and closing the air passage hole 5, and a stopper 35 to which the female screw thread from which some regions are removed is formed and coupled to the coupler 9.

The blocking plate 31 is made of soft silicon, and has a plate portion 32 for opening and closing the air passing hole 5 and a fixing hook 33 protruding from the central region of the plate portion 32 to be coupled to the fixing hole 7. ).

The stopper 35 is formed in a cylindrical shape with one side open, and as shown in FIG. 3, a female thread is formed inside the sidewall of the stopper 35. The female thread formed on the stopper 35 has one region removed along the circumferential direction. Accordingly, when the stopper 35 is loosened slightly when the stopper 35 is coupled to the coupler 9, the inflow of air from the outside into the stopper 35 is prevented. It becomes possible. Accordingly, when the stopper 35 of the intake valve 30 is loosely tightened to allow the inflow of air, the pump is applied to the air inlet valve 20 and the air is sucked in, so that the moving plate 15 receives the air inlet valve 20. ), The air is sucked into the intake valve 30, and the space between the movable plate 15 and the lid 3 is narrowed.

The stopper 35 is formed inside the stopper 35 so as to protrude in a concentric manner with the side wall of the stopper 35 to be in contact with the inner wall surface of the coupler 9. The packing 40 is placed between the inner surface of the coupler 9 and the inner stopper 36 to maintain the airtightness when the stopper 35 is engaged.

Referring to the process of storing and withdrawing food in the vacuum storage container by such a configuration as follows. First, the movable plate 15 is disposed adjacent to the bottom surface of the container body 2, and food is accommodated in the container body 2 in a state where the stopper 35 of the suction valve 30 is opened. Then, the lid 3 is closed, and a pump is applied to the air inlet valve 20 to suck air in the container body 2. Then, the movable plate 15 moves toward the lid 3 by the suction force of the pump, and air flows into the lower portion of the movable plate 15 in the container body 2 through the suction valve 30. When the vacuum is formed, tightly stopper 35 to prevent the outflow of air.

On the other hand, when the food is drawn out, the push button of the air inlet and outlet valve 20 is pressurized to introduce the air in the container body 2. At this time, since the air flows into the lower portion of the moving plate 15, even if air flows into the space in which the food in the container body 2 is stored, the moving plate 15 does not descend.

As described above, the food vacuum container 1 of the present invention has a movable plate 15 and a suction valve 30 so that the movable plate 15 is movable, thereby varying the storage space of the food according to the amount of food. You can do it. Accordingly, since the amount of food is reduced, the vacuum can be easily formed and released without releasing and introducing a large amount of air for vacuum formation and release. In addition, since the moving plate 15 does not move even when the vacuum is released, the food is easily taken out even when the sealed container is deep.

As described above, according to the present invention, not only the vacuum formation and release can be easily performed, but also the food can be taken out easily.
