Definitions
- the present invention relates to a vacuum storage container and a vacuum storage method for food, and more particularly to a vacuum storage container and a vacuum for food that can store food without compressing the food in a substantially reduced-pressure space in a certain space while heating and cooking the food. Regarding how to save. Background art
- the first example is a method in which a bag made of a synthetic resin film is sealed by suction-removing air from the bag in a state where food is stored in a vacuum chamber.
- the second example is a method using a pressure cooker, in which food is put into a pressure cooker, heated, and the generated steam is discharged.Then, when the pot is sealed, the remaining water vapor liquefies and the inside of the pot is almost completely filled. The fact that the pressure is reduced to a vacuum state is used.
- the film is pressed by the external air pressure, so that the film adheres to the food and is pressed, so that the film is compressed with a soft food, causing deformation, out of shape, or not being brewed.
- the texture is impaired when returned to the original state.
- an object of the present invention is to use an inexpensive and simple material such as a synthetic resin film and cook food in a space having a certain shape retention property. Accordingly, an object of the present invention is to provide a vacuum storage container and a vacuum storage method that can reduce the pressure to a substantially vacuum state and store food without compressing it. Disclosure of the invention
- a vacuum storage container for food includes a dish member for holding food, and a cover member having shape retention for covering the food placed on the dish member.
- a bag body made of a non-breathable synthetic resin film having a check valve capable of discharging the gas inside and preventing the flow of gas from the outside and having an opening on one side for taking food in and out.
- a plurality of small holes are formed in the cover member, or a gap is formed between the cover member and the plate member with the cover member covered, and the cover member is placed on the plate member and covered with the cover member.
- the resulting food is put into the bag body, and water vapor generated by heating the food with the opening of the bag body closed is exhausted from the check valve to the outside of the bag body, and the heating is terminated. Thereafter, a reduced pressure space is formed in the bag body based on the liquefaction of the remaining steam.
- the food to be cooked and stored is placed on a dish member and covered with a cover member, and is stored in a bag body in this state.
- An openable / closable chuck is attached to the opening on the side of the bag body for taking in and out the food, and the airbag can be closed in an airtight manner. It is preferable that airtight closing can be achieved by sealing.
- the food stored in the bag body with the opening airtight is put into a microwave oven with the bag body, and is heated and cooked.
- water vapor is generated from the food, the bag body expands, and the water vapor is exhausted from the check valve to the outside of the bag body.
- the water vapor remaining in the bag body liquefies
- the inside of the bag body is decompressed, and the film of the bag body comes into close contact with the plate member and the cover member, thereby maintaining the decompressed state.
- water vapor is liquefied, its volume is reduced to about 1/900, the air pressure inside the bag body is greatly reduced, and the pressure is reduced to a level close to vacuum.
- the food is stored at any location, for example, in a refrigerator or freezer, for any period of time without being compressed under reduced pressure. To remove food from the bag body, open the chuck at the opening or cut the bag body.
- the food is held in a shape-retaining space having a predetermined shape composed of a dish member and a cover member, and the shape-retaining space and the inside of the bag body are formed by a plurality of small holes or cover members formed in the cover member. And a dish member are communicated via a gap formed between the plate member and the plate member. Further, the small holes or gaps need to have such a size that the resin film of the bag body is not drawn into the shape-retaining space when the inside of the bag body is depressurized. A slight pull-in also allows for visual confirmation of vacuum, which is rather desirable.
- the vacuum storage container and the vacuum storage method for food according to the present invention do not use a large and expensive container like a conventional pressure cooker, but are inexpensive and compact. Can be stored in a vacuum, which allows several types of food to be stored individually in vacuum.
- the inside of the container is sealed with a non-breathable film, the shape-retaining space for avoiding the compression of food is secured by the cover member, and the internal pressure is reduced. It utilizes the volume reduction due to the liquefaction of water vapor, and can cook and store food in a vacuum with a simple configuration.

- FIG. 2 is a cross-sectional view of the vacuum storage container
- FIG. 3 is a sectional view showing a check valve of the vacuum storage container
- FIG. 4 is a perspective view showing a chuck of the vacuum storage container.
- FIG. 1 shows a vacuum storage container for food according to the present invention, which comprises a bag body 10, a plate member 20 and a cover member 25.
- the bag body 10 is made of a non-breathable synthetic resin film 11a, lib, one side of which is an opening 12 for taking in and out of food, and the inner side of the opening 12 covers the entire width thereof. Openable and closable chuck 15 is welded. On the other side 13 of the bag body 10, films 11a and lib are welded, and a check valve 18 is attached.
- the bag body 10 is a so-called fusing bag in which both sides a, a are blown, or a three-side bag in which three sides are welded and cut, and the resin films 1 la, 11 b are made of Laminated material, heat-sealable synthetic resin film on the inner side (eg, polyethylene film, polypropylene film)
- a non-breathable synthetic resin film eg, polyethylene terephthalate finolem, polyamide finolem
- the materials of the films 11a and 11b described above are merely examples, and various resin materials can be used in addition to these, and it is not necessary to be a laminate material.
- the chuck 15 is composed of an arrow-shaped convex part 15 and a concave part 15c formed on the base part 15a.
- the chuck 15 used in the present embodiment has a fitting strength of 13 NZ5 Omm on the opening side, can be opened with a relatively small force, and has a fitting strength of 59 9 on the non-opening side. It is N / 5 O mm, and it is difficult to open it without a very large force.
- the check valve 18 is a flat cylindrical body formed by laminating two synthetic resin films 18a and 18b and welding or bonding both sides thereof.
- the outer surfaces of the finolems 18a and 18b are welded to the inner surfaces of the finolems 11a and 11b of the bag body 10.
- This check valve 18 can discharge the gas inside the bag body 10 when the internal pressure of the bag body 10 increases, and when the internal pressure of the bag body 10 decreases, the films 18a and 18b come into close contact by the depressurizing action.
- the inside of the bag body 10 is kept airtight.
- the dish member 20 may be formed of various materials as long as it has rigidity. However, as will be described later, if the food is to be cooked and heated in a microwave oven, ceramics, heat-resistant glass, and the like are preferable. .
- the shape can be square or circular.
- the cover member 25 is for covering the food A placed on the plate member 20 to form a constant space 14 with the plate member 20. It is made of a material having a shape-retaining property. Forming it with a transparent hard resin is advantageous in terms of manufacturing cost and ease of handling, or e is preferable in that the stored food can be visually checked. Further, a plurality of small holes 26 are formed in the ceiling surface of the cover member 25.
- the food A containing or adding water to be cooked and stored is placed on the plate member 20 and covered with the cover member 25, and in this state, the opening is opened.
- the bag is stored in the bag body 10 from 12 and the chuck 15 is closed.
- the food A stored in the bag body 10 with the opening 12 airtight is put into a microwave oven with the bag body 10 for heating and cooking.
- the moisture in the food A evaporates, the bag body 10 expands, and water vapor is exhausted from the check valve 18 to the outside of the bag body 10.
- the water vapor remaining in the bag body 10 is liquefied, so that the inside of the bag body 10 is decompressed, and the films 11 a and 11 b are dissipated from the plate member 2. 0 and the cover member 25, and maintain the reduced pressure state.
- the air pressure in the bag body 10 is greatly reduced, and the pressure is reduced to a level close to vacuum.
- Food A is stored in this decompressed state and without being compressed in an arbitrary place for an arbitrary period, for example, a refrigerator or a freezer.
- the chuck 15 of the opening 12 may be opened.
- the chuck 15 has a large fitting strength on the non-opening side, so there is no danger of opening when the bag body 10 is inflated. It can be easily opened from.
- the food A is held in the decompressed space 14 having a fixed shape constituted by the dish member 20 and the cover member 25.
- the shape-retaining space 14 and the bag body 10 are formed on the cover member 25.
- the plurality of small holes 26 communicate with each other, and the same pressure is maintained in the shape-retaining space 14 and the inside of the bag body 10.
- the vacuum storage container By using the vacuum storage container, a fixed space 14 was secured between the film 11a and the lib and the food A in a state where the film 11a and lib did not crimp, that is, the plate member 20 and the cover member 25.
- the cooked food can be stored under reduced pressure in a substantially vacuum state.
- food A is not pressed or deformed by the finolene 11a and 11b, and does not lose its shape.
- the upper surface of the cover member 25 is flat. This is because it is possible to stack several containers that contain food under reduced pressure.
- vacuum storage container and the vacuum storage method for food according to the present invention are not limited to the above embodiment, and can be variously changed within the scope of the gist.
- the film in the opening 12 is formed using a simple heat sealing device that can be used at home without installing the chuck 15 in the opening 12 of the bag body 10. This is to thermally weld 11a and 11b. In this case, the inside of the heat-welded part is forced to take out the food. If the length L (see Fig. 1) of the opening 12 has a margin, the same bag body 10 can be used two or three times.
- check valves for discharging steam can be used. If food is to be stored for a long period of time, the pressure inside the bag body 10 should be reduced, and then the films 18a and 18b of the check valve 18 should be heat-sealed. Is also good. Further, the plate member 20 and the cover member 25 may be partitioned into a plurality of shape-retaining spaces.
- the vacuum storage container and the vacuum storage method according to the present invention can cook and vacuum store food with a simple configuration, and can store food under reduced pressure while keeping its shape. Extremely useful.
