Description

Airtight Container

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. 10-0429069 discloses a vacuum container for storing food having a vacuum generating device.

The vacuum container for food preservation is characterized in that a piston member is provided so as to be able to be lifted and lowered on a lid member that covers an upper portion of a container member for housing food, and by the pumping action of the piston member, The valve members alternately open and close the intake port and the exhaust port while alternately discharging the air filled in the container member to the outside so that the inside is in a vacuum state.

The vacuum container includes a valve guide member, an upper cap member, and a lower cap member in addition to the lid member, the piston member, the first valve member, and the second valve member, There is a problem that it is difficult to manufacture and assemble because of a large number and a complicated structure.

Further, since the space occupied by the vacuum generating means in the lid member is relatively large, there is a problem that the volume of food for storing the food is reduced.

In addition, dimensional precision of parts constituting the vacuum generating means is required, which is not only difficult to manufacture but also has a problem of low reliability of operation.

The present invention has been devised in order to solve the above-mentioned problems, and it is an object of the present invention to provide a deaerator having a small number of components and a simple structure, easy to manufacture and assemble and a relatively small volume, It is an object of the present invention to provide an airtight container provided with a degassing device which does not require precision and is easy to manufacture and reliable in operation.

To achieve the above object, the sealed container of the present invention comprises: a container body for storing food; A cover coupled to cover the opened upper surface of the container body and provided with a concave downwardly from an upper surface thereof; And a deaerator mounted on the concave portion and deaerating the air inside the container body, wherein the deaerator has a button member mounted on the concave portion so as to expose an upper portion thereof, A lower cap attached to a lower surface of the expansion and contraction pump and provided with an intake valve that is opened when the expansion and contraction pump is expanded, And an upper cap attached to an upper surface of the expansion and contraction pump and provided with an exhaust valve that is opened when the expansion and contraction pump is retracted.

Preferably, the stretchable and contractible pump includes an upper face portion formed with a vent hole at the center, a side face portion formed to be wrinkled so as to be stretchable in the vertical direction, and a lower face opening having a lower end inside portion of the side face portion.

Preferably, the lower cap is attached to the lower end of the side face of the expansion and contraction pump by thermal fusion, and the upper cap is attached to the upper face edge of the expansion and contraction pump by thermal fusion.

Preferably, the intake valve is a hinged valve formed at the center of the lower cap, and an intake hole that is opened and closed by the intake valve is formed through the bottom surface of the recess.

The exhaust valve may be a hinged valve formed at the center of the upper cap, and the exhaust valve may be rotated upward to open the exhaust hole when the expansion and contraction pump is retracted.

The deaerator further includes a guide support portion extending upward from the bottom of the concave portion and spaced from the inner side surface of the concave portion by a predetermined distance, wherein the guide support portion is provided with guide grooves on its side wall, And a guide protrusion extending inwardly and inserted and guided in the guide groove.

The elastic member is preferably a spring spring that is vertically and vertically stretchable between an upper surface portion of the expansion and contraction pump and the lower cap.

The button member is preferably provided with a pushing portion which protrudes downward from the lower surface thereof to press the upper cap.

The pressing portion is formed to press an edge portion surrounding the exhaust valve in the upper cap, and the pressing portion includes a communication portion formed by cutting a side wall of the pressing portion so that the air discharged through the exhaust valve can flow to the outside of the pressing portion .

The deaerator may further include an intake port cover mounted to surround the concave portion to prevent moisture from flowing into the deaerator.

The intake port cover preferably includes a plurality of ribs provided on the inner surface thereof to form a gap for air inflow from the outer surface of the recessed portion.

As shown in FIG. 4, the concave portion 150 may have a cylindrical shape with an open upper surface.

5, the button member 250 may have a cylindrical shape with an opened lower surface.

3, the button member 250 may be slidably mounted on the inner surface of the recess 150 while the outer surface thereof is supported by the inner surface of the recess 150. As shown in FIG.

The button member 250 is mounted so as to protrude upward from the upper surface of the lid 110 so as to be easily pressed by the user.

As shown in FIG. 6, the expansion and contraction pump 210 may have a corrugated pipe shape that is expanded and contracted in the vertical direction so that the volume of the inner space can be reversibly increased or decreased.

The stretchable and contractible pump 210 may be made of, for example, a silicone resin or a silicone rubber, and may be elastically deformed in order to allow the corrugated pipe to be easily expanded and contracted.

The expansion and contraction pump 210 includes an upper portion 211 formed with an exhaust hole 212 at the center thereof, a side portion 213 formed to be wrinkled so as to be vertically extendable and contractible, and a lower opening 215).

The expansion and contraction pump 210 may have a cylindrical shape with an open bottom as a whole and an outer diameter of the expansion and contraction pump 210 may be smaller than an inner diameter of the recess 150.

The upper surface portion 211 is integrally connected to an upper end portion of the side surface portion 213 to block the upper surface of the expansion and contraction pump 210.

On the other hand, the lower surface of the expansion and contraction pump 210 is opened to form a lower surface opening 215.

The elastic member 260 provides a restoring force for expanding the stretchable pump 210 which is retracted by the button member 250 which is mounted in the stretch pump 210 and pushed.

The elastic member 260 is preferably a spring spring whose upper end is in contact with a lower surface of the upper surface portion 211 of the expansion and contraction pump 210.

The lower cap 220 is attached to the lower end of the expansion and contraction pump 210 to close the inside of the expansion and contraction pump 210 and has an intake valve 222 at the center, So that the intake air holes 155 formed in the through holes 155 can be selectively opened and closed.

The intake valve 222 is a hinged valve formed at the center of the lower cap 220. When the expansion and contraction pump 210 is expanded, the valve 222 is opened through the intake hole 155, May be introduced into the expansion and contraction pump 210.

The upper cap 240 is attached to the upper surface 211 of the expansion and contraction pump 210 to selectively open and close the exhaust hole 212 formed in the center of the upper surface 211.

The exhaust valve 242 is a hinged valve formed at the center of the upper cap 240. When the expansion and contraction pump 210 is contracted, the expansion valve 242 is opened through the intake hole 155, The air inside can be discharged to the outside.

The lower cap 220 and the upper cap 240 may be made of silicone resin or silicone rubber so that the intake valve 222 and the exhaust valve 242 may be elastically deformed.

The lower cap 220 is attached to the lower end of the side portion 213 of the expansion and contraction pump 210 by thermal fusion and the upper cap 240 is attached to the edge of the upper surface portion 211 of the expansion and contraction pump 210 It is preferable to be attached by heat fusion.

When the lower cap 220 and the upper cap 240 are attached to the expansion and contraction pump 210 by using a separate adhesive, the adhesive force between the two members elastically deformed may cause air leakage.

Therefore, even if the lower cap 220 and the upper cap 240 are attached to the expansion and contraction pump 210 by thermal fusion, even if they are used as a single component, the possibility of air leakage is reduced .

As shown in FIG. 7, the lower cap 220 and the upper cap 240 may have the same shape.

It is preferable that the intake valve 222 and the exhaust valve 242 are formed in a shape of "C" shape and their diameter is formed to be much larger than the diameter of the intake hole 155 and the exhaust hole 212, respectively Do.

The intake valve 222 may be in close contact with the bottom surface of the recess 150 by the pressure when the expansion and contraction pump 210 is contracted to seal the intake hole 155.

The exhaust valve 242 may be downwardly pressed against the upper surface portion 211 of the expansion and contraction pump 210 by the pressure when the expansion and contraction pump 210 is inflated to seal the exhaust hole 212.

3, the elastic member 260 may be mounted in a slightly compressed state between the upper surface portion 211 of the expansion and contraction pump 210 and the lower cap 220. As shown in FIG.

The elastic member 260 applies an elastic force to push the button member 250 upward without pushing the button member 250 so that the elastic member 260 is fixed to the button member 250 to prevent the button member 250 from moving when the button member 250 is in the upper position. .

8, the elastic member 260 includes a lower horizontal portion 262 so that the lower end of the spring spring can contact the horizontal surface, and an upper horizontal portion 264 at the upper end portion desirable.

The upper end of the elastic member 260 is formed to have a sharp tip so that the upper surface portion 211 of the elastic pump 260 Repeatedly pushing up is likely to tear the upper surface portion 211.

Therefore, by forming the upper and lower ends of the elastic member 260 as horizontal portions 262 and 264 so as to be in surface contact with the horizontal plane, force is applied to the elasticized pump 210 in a concentrated manner, It is possible to prevent the expansion / contraction pump 210 from being damaged or damaged.

4, the concave portion 150 may be provided with a guide support portion 160 extending upward from the bottom and spaced apart from the inner side surface of the concave portion by a predetermined distance.

The guide supporting part 160 may be integrally formed with the concave part 150. Since the concave part 150 is formed in a cylindrical shape, the guide supporting part 160 may be formed in a cylindrical shape.

The guide support portion 160 has a guide groove 162 on its side wall and a guide protrusion 256 extending inwardly from the lower end of the button member 250 to be inserted and guided in the guide groove 162 .

The pair of guide grooves 162 may be formed at a middle height at a position facing each other on the side wall of the guide support portion 160.

5, a pair of the guide protrusions 256 may extend inwardly at positions opposite to each other at the lower end of the button member 250. As shown in FIG.

The guide protrusion 256 is guided by the guide groove 162 so that the button member 250 can be guided to move only up and down without being rotated, Can be limited.

That is, when the user pushes the button member 250 to the end, the button member 250 can be moved downward to a position where the guide protrusion 256 is supported at the lower end of the guide groove 162.

On the other hand, when the user releases his or her hand from the button member 250, the button member 250 is supported by the upper end of the guide groove 162 by the restoring force of the elastic member 260 To the position.

The distance between the pair of guide protrusions 256 may be smaller than the inner diameter of the guide support portion 160.

The button member 250 integrally formed with the guide protrusion 256 is made of a synthetic resin capable of performing a predetermined elastic deformation so that when the button member 250 is pressed down during assembly, It can be inserted and mounted in the guide groove 162 while being elastically deformed.

The button member 250 may be provided with a pressing part 252 protruding downward from the bottom surface of the button member 250 to press the upper cap 240.

The exhaust valve 242 provided in the upper cap 240 is pivoted and opened upward when opened so that the pressing portion 252 is positioned between the button member 250 and the upper cap 240 and the exhaust valve 242 Can be rotated.

The pushing part 252 may be integrally formed on the button member 250 in the form of a circular pipe having a predetermined height.

Therefore, the pressing portion 252 may be formed to press the peripheral portion of the exhaust valve 242, that is, the periphery of the exhaust valve 242, in the upper cap 240.

The push portion 252 may further include a communication portion 253 formed by cutting the side wall of the push portion 252 so that the air discharged through the exhaust valve 242 flows to the outside of the push portion 252 desirable.

Therefore, the pressing portion 252 may be formed in a "C" shape except for the communicating portion 253.

The air flowing through the communication part 253 flows into the space between the inner surface of the button member 250 and the outer surface of the stretch pump 210 and then the outer surface of the button member 250, (Not shown).

3 and 9, the deaerator 200 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 bottom surface of the concave portion 150 is formed with the intake holes 155 so that the air can be introduced into the bottom surface of the concave portion 150, Moisture may be introduced into the degassing apparatus 200 through the air intake hole 155 when the air is stored at a higher 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 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 may include a plurality of side ribs 272 formed on the inner surface of the intake port cover 270 so as to be long in the vertical direction and a plurality of side ribs 272 extending in the radial direction toward the center on the bottom surface of the intake port cover 270. The side ribs 274 may be formed on the inner surface of the side surface of the substrate.

The plurality of ribs 272 and 274 are formed such that a gap is formed between the intake port cover 270 and the outer surface of the recess 150 to allow air to flow into the air intake hole 155 through the gap Can be guaranteed.

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.

The operation of the degassing apparatus will be described with reference to Fig.

As shown in FIG. 10 (a), when the user presses the button member 250, the expansion and contraction pump 210 contracts and the pressure inside the expansion and contraction pump 210 increases.

At this time, the intake valve 222 of the lower cap 22 is closely contacted downward to keep the airtight state.

The air discharged through the exhaust valve 242 is discharged to the outside through the gap between the button member 250 and the recess 150.

As shown in FIG. 10B, when the button member 250 is depressed by the user, the elastic member 260 inflates the stretchable and contractible pump 210 to lower the pressure inside the stretchable and contractible pump 210 .

The intake valve 222 of the lower cap 22 is opened so that the gap between the intake port cover 270 and the outer surface of the recess 150 and the gap between the inside surface of the container body 130 Air is introduced into the expansion and contraction pump 210.

At this time, the exhaust valve 242 of the upper cap 240 maintains the closed state because the pressure inside the expansion and contraction pump 210 is low.

When the user again presses the button member 250, the air inside the stretch pump 210 may be discharged to the outside of the degassing apparatus 100, as shown in FIG. 10 (a).

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.
