BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a hermetically sealed container, and more particularly, to a hermetically sealed container having a degassing device for discharging air in an inner space of a hermetically sealed container.

Generally, foodstuffs such as various vegetables and fish have a problem that they are easily oxidized and corrupted due to contact with microorganisms contained in the air or other harmful substances such as oxygen when they come into contact with the outside air.

In addition, in the case of fermented foods, the propagation of the microorganisms is further activated, and the fermentation and aging speed of the food is promoted too quickly, and thus there is a poor shelf life.

On the other hand, in order to delay the fermentation and decay of food, it is most preferable to block the inside of the container filled with the contents from the outside, and to keep the inside of the container in a vacuum state.

To this end, it has been developed to provide a degassing device capable of extracting air inside the sealed container.

As an example of such a hermetically sealed container, Japanese Patent Application Publication No. 10-0689195 discloses a food storage container having a vacuum generating device.

The food storage container includes a pair of air discharging portions fixed at a predetermined length apart from a top surface of a lid of a container for accommodating food and allowing the air inside the container to be alternately discharged to the outside; A connecting portion connecting the air discharge portions on both sides of the diaphragm having a constant diameter by a guide rod and allowing air to flow through the guide rod; And an actuating part having an inner diameter capable of slidably moving with an inner diameter surface of the O-ring coupled to the outer diameter of the diaphragm being closely contacted and having a shape surrounding the outer circumference of the guide rod and sliding along the guide rod to perform a pumping action .

However, since the above-described conventional food storage container is mounted so that the vacuum generating device protrudes from the upper surface of the lid of the container, not only the appearance of the container is damaged but also the food storage container is easily damaged by external impact .

Further, the structure of the vacuum generating device is complicated and the amount of air that can be discharged at a time is small compared with the size thereof, which is inconvenient to use.

As shown in FIG. 2, the communication groove 225 may be provided on the upper portion and the lower portion of the attachment portion 224.

Since the attachment portion 224 is attached to the side surface of the expansion and contraction pump 210 so that the inner space of the central groove portion 222 can be sealed, the communication groove 225 is provided in the attachment portion 224 The air discharged through the exhaust part 214 may be discharged from the central groove 222 to the outside when the exhaust valve 230 is opened.

The side surface of the extensible pump 210 on the side of the intake portion 212 may be attached to the inner surface of the recess 150 by thermal fusion.

One side surface of the stretch pump 210 is thermally fused to the inner surface of the recess 150 and the other side surface of the stretch pump 210 is thermally fused to the side surface of the slider 220, The pump 210 may be supported in a state where its bottom surface is spaced apart from the bottom surface of the concave portion 150.

On the other hand, the lower surface of the slider 220 can be slidably supported by contacting the bottom surface of the recess 150.

The slider 220 may further include a handle 240 extending upward from an upper end of the slider 220 and protruding higher than an upper surface of the lid 110.

The handle 240 is integrally connected to the slider 220 and protrudes upward from the upper surface of the lid 110 so that the user can move the slider 220 to the left or right by moving the handle 240 to the left or right Can be moved.

The deaerator 200 may further include a pump cover 250 covering an upper surface opening of the concave portion 150.

The pump cover 250 may be inserted into the opening of the upper surface of the recess 150 so that its upper surface is coplanar with the upper surface of the lid 110.

The recess 150 may have at least one support rib 157 for supporting the pump cover 250 inside the upper end thereof.

In addition, the pump cover 250 may include a guide slot 254 for slidably supporting the handle 240.

The handle 240 may have a vertically long rectangular column shape and may be mounted to pass through the guide slot 254 so that the front and rear surfaces thereof can be slidably supported on the rear surface and the front surface of the guide slot 254. [ have.

The guide slot 254 guides the movement of the handle 240 and restricts the range of movement of the handle 240.

When the pump cover 250 is moved to one side, one of the pair of pump covers 250 expands and the other pump cover 250 contracts.

Accordingly, in the pump cover 250 that expands, air flows out into the container body 130 in the pump cover 250 in which air flows in from the inside of the container body 130 and is contracted.

The handle 240 may further include a horizontal extension portion 242 contacting the lower surface of the pump cover 250 and covering the guide slot 254 from below.

The horizontal extension portion 242 may extend laterally from the lower end of the handle 240, which is connected to the slider 220.

The horizontal extension part 242 may be formed long enough to cover the guide slot 254 even when the horizontal extension part 242 moves left and right together with the handle 240.

2, the deaerator 200 further includes an intake port cover 270 mounted to surround the concave portion 150 to prevent moisture from flowing into the deaerator. .

As described above, the suction holes 155 are formed on both sides of the recess 150 so that food containing moisture can be introduced into the container body 130 from the inlet holes 155 Moisture can be introduced into the degassing apparatus 200 through the intake holes 155 when stored at a high level.

Therefore, the intake port cover 270 may be mounted so as to enclose the recess 150 from below to prevent water from flowing through the intake port 155.

The intake port cover 270 may be made of silicone resin or silicone rubber and may be mounted on the recess 150 in close contact therewith.

However, a slight clearance due to dimensional tolerance is formed between the intake cover 270 and the outer surface of the recess 150, so that air can be introduced through the gap.

That is, water can not pass easily between the intake port cover 270 and the outer surface of the recess 150, but a gap through which air can pass can be formed.

The intake port cover 270 may include a plurality of ribs 272 provided on the inner surface thereof to form a gap for air inflow from the outer surface of the recessed portion 150.

The plurality of ribs 272 ensure that there is a clearance between the intake port cover 270 and the outer surface of the recess 150 to allow air to enter.

In this case, when the food containing moisture is stored in the container main body 130, the height of the food may be larger than the height of the inlet cover 270 so that the container body 130 is not tilted as well.

Fig. 5 shows the operating state of the deaerator according to the present invention.

When the user pushes the handle 240 to the right side, the slider 220 is moved to the right side, and the left extensible pump 210 is expanded and the right extensible pump 210 is contracted.

At this time, the intake valve 215 is opened and the exhaust valve 230 is closed by the pressure difference in the left extensible pump 210 so that the air inside the container body 130 flows into the intake valve 215, And then flows into the expansion and contraction pump 210 through the expansion valve 210.

At the same time, the intake valve 215 is closed and the exhaust valve 230 is opened by the pressure difference in the right extensible pump 210 so that the air inside the expansion pump 210 flows into the exhaust valve 230, And is discharged to the outside of the expansion and contraction pump 210 through the expansion valve 210.

The air flowing out from the expansion and contraction pump 210 in the recess 150 can be discharged to the outside through the gap between the pump cover 250 and the recess 150.

Next, when the user pushes the handle 240 to the left side, the slider 220 is moved to the left side, and the left and right extensible pump 210 contracts and the right elastic pump 210 expands.

Thus, the air in the left extensible pump 210 is discharged to the outside, and the air inside the container body 130 can be introduced into the right extensible pump 210.

According to the present invention, when the user moves the slider to one side, air is sucked and discharged simultaneously by a pair of stretching pumps. Therefore, since air can be discharged twice when the slider is moved left and right, The air can be discharged in a large amount and efficiently, and it is easy for the user to operate.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, Changes will be possible.
