Description

  The present invention relates to a method for preserving various foods using a commercially available storage bag, and a food storage storage bag used exclusively for executing the method.

  There are cases where it is desired to store fresh foods and processed foods purchased in the market, or cooked foods in ordinary households. Usually, as a storage bag used for the preservation of these foods, there is known a bag that can be sealed with a fastener that is slid on the opening side of the bag body or a chuck that engages with an unevenness (hereinafter, the interior is sealed). The structure having the function to perform is collectively referred to as sealing means). After storing food, such a storage bag is stored in a refrigerator or the like, and next time it is eaten, it is heated as it is in a microwave oven or transferred to another container and heated in a microwave oven. .

  However, the above-described storage bag cannot sufficiently deaerate the internal air, and the food may be spoiled during storage. For example, the storage bag disclosed in Patent Document 1 2. Description of the Related Art A food storage bag is known in which a sealing means for sealing is provided at one end of a bag and a check valve is provided at the other end. Such a food storage bag stores food inside and closes the sealing means, and then sucks the internal air with a dedicated deaeration pump through the check valve to make the inside oxygen-free. It effectively prevents the decay, alteration, and taste of the contained food.

Utility Model Registration No. 3045689

  In the above-described known food storage bag, when food is actually stored, the storage work is troublesome because the deaeration pump is connected to the deaeration pump after the food is stored. In addition, since a check valve is provided, it is possible to discharge the internal air by manually pressing the storage portion containing the food, but it is troublesome to perform sufficient deaeration. It is difficult as well as causing problems in the storage state. That is, conventionally, with known food storage bags, the stored food cannot be easily and reliably prevented from being spoiled, denatured, or altered.

  The present invention has been made paying attention to the above-mentioned problems, and relates to various foods to be stored. A method for storing foods that does not cause spoilage, alteration, and alteration easily and reliably, and storage for food storage. The purpose is to provide a bag.

  In order to achieve the above-described object, the food storage method according to the present invention forms a storage portion by overlapping the periphery of a pair of heat-resistant sheet-like members, and allows the food to be taken in and out by opening and closing the storage portion. A state in which food is stored in the storage unit when the food is stored using the food storage storage bag having sealing means and a check valve that allows the air in the storage unit to flow outside and prevents the inflow of outside air And a step of irradiating with microwaves for a certain period of time, and a step of naturally cooling the food storage container bag irradiated with microwaves for a certain period of time and storing in a refrigerator.

In order to achieve the above-mentioned object, the food storage container according to the present invention is placed in a microwave oven in a state where food is stored and irradiated with microwaves for a certain time, and then naturally cooled for a certain time, It is assumed that it will be used afterwards for storage in a refrigerator, and is defined by the welded portion formed around the pair of heat-resistant sheet-like members overlapped with each other, and contains the food. And a sealing means that is formed without welding a part of the periphery of the pair of sheet-like members, and is provided in an opening region that allows food to be taken in and out of the storage portion, and allows the storage portion to be sealed. , which is connected with the accommodating portion, the air in the housing portion so as to prevent the inflow of outside air as well as discharged to the outside, by cutting one end of said sheet-like member, the ends by bending the both portions cut Overlapping inner surfaces, and having a easy peelability of the check valve disposed in the middle portion, together with welding the overlapped portion.

  In general, microwave ovens used at home are mainly used for cooking foods or thawing frozen foods and using them to store foods. Nothing is taken into account. For this reason, although various types of storage bags for storing food are known, none of them has a structure suitable for storing food using a microwave oven.

  The present invention has been conceived based on the current situation, and according to the food storage method and the food storage container described above, first, the sealing means is opened and food (fresh food, Processed food, cooked food, etc.) are stored, and the sealing means is closed to seal the inside. In this state, it is placed in a microwave oven and heated for a certain period of time (appropriately set depending on the food to be accommodated and the wattage of the microwave oven) and irradiated with microwaves. At this time, the temperature in the accommodating portion becomes high and the air inside expands, but this expanding air is discharged to the outside through the check valve. Moreover, the bactericidal effect with respect to a foodstuff is acquired by this microwave irradiation and a heating. And after heating in a microwave oven, if it cools naturally for a fixed time, the air which remains in an accommodating part will be discharged | emitted by a pressure reduction effect | action, and an inside will be in a vacuum state. The storage bag in a vacuum state can be stored for a long period of time by storing it in a refrigerator or the like, without the food inside being spoiled, altered or altered.

  ADVANTAGE OF THE INVENTION According to this invention, the food preservation method and food storage container which do not produce spoilage, quality change, and a taste are obtained easily and reliably regarding various foods to preserve | save.

The perspective view which shows the storage bag for food preservation which concerns on one Embodiment of this invention (The heat welding part is shown with a diagonal line.). Sectional drawing along the AA line of FIG.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
1 and 2 are views showing an embodiment of a storage bag used in the food storage method according to the present invention, FIG. 1 is a perspective view showing a food storage storage bag, and FIG. It is sectional drawing along the AA line.

  As shown in the figure, a food storage storage bag (hereinafter referred to as a storage bag) 1 according to the present embodiment includes a bag body 1A that defines a sealable internal space (storage unit) S. The bag body 1A has flexibility and is created by superposing a pair of rectangular synthetic resin sheets (sheet-like members) 3 and 4, and heat-sealing the periphery shown by the oblique lines in FIG. 1 with a heat bar or the like. Is done. Specifically, the bag body 1A is formed by thermally welding the side edge portions 5 and 6 and the lower edge portions 7 of the stacked sheet-like members. Further, the upper edge portion 8 facing the lower edge portion 7 is not welded, and becomes an opening portion 8A for taking food into and out of the accommodating portion S.

In the present embodiment, one end side of the sheet-like member 3 on the one side is cut, both of the cut portions are folded and the inner surfaces of the end portions 3a and 3b are overlapped, the overlapping portions are welded, An easily peelable check valve 10 is disposed in the middle portion. Since this easily peelable check valve is known, its detailed structure is omitted.

  The sheet-like members 3 and 4 only need to be formed of a heat-resistant material, and are composed of a plurality of layers including a base layer serving as a base material and a welding layer (sealant layer) on which welding is performed. ing. The basic layer constitutes the outer layer side, and may be any material as long as it is composed of a material having both barrier properties (deodorant properties) and heat resistance, and the material is not particularly limited. For example, it can be composed of polyethylene terephthalate, polyethylene naphthalate, polybutylene terephthalate, polyethylene film, polypropylene, nylon, etc., and this may be a single layer structure or a composite layer structure. Further, the sealant layer constitutes the inner layer side, and any material may be used as long as it is made of a material that can be thermally welded to the mating sheet-like member, and the material is not particularly limited. For example, it can be composed of polyethylene, ionomer, polypropylene or the like.

  The upper edge 8 is provided with sealing means 20 for sealing the opening 8A (accommodating portion S). The sealing means 20 includes, for example, a concave groove 20a formed over the entire inner surface of the opening portion of the sheet-like member 3 on one side and an inner surface of the opening portion of the sheet-like member 4 on the other side. It can be configured (fastener structure) by a convex portion 20b formed over the entire length and engaged with the concave groove 20a in a sealed state. These concave grooves 20a and convex portions 20b may be configured to be attached to the belt-like sheet member and attached to the inner surfaces of the respective openings.

  The check valve 10 may have a simple structure in which an openable / closable sealing piece that opens toward the outside when the internal pressure in the accommodating portion S increases, and the specific configuration is particularly limited. Never happen. That is, there is no limitation on the structure as long as it is connected to the housing part S and functions to prevent the inflow of outside air while discharging the air in the housing part to the outside, and the structure is not limited. There are no restrictions on the position, arrangement, and number of installations.

  Since the above-described storage bag 1 is placed in a household microwave oven, its size is limited. Specifically, as shown in the figure, the plane L may have a length L in the range of 190 to 230 mm, and the opening width W may be in the range of 150 to 170 mm. That is, if a bag main body is formed in such a size, the following preservation | save processes and the thawing | decompression process can be implemented using a general household microwave oven.

Next, the process of preserving food using the storage bag 1 configured as described above will be described.
First, food is accommodated in the accommodating part S through the opening 8A, and the opening 8A is closed by the sealing means 20 so that the accommodating part S is sealed.

  In this state, it is placed in a microwave oven and heated for a certain time to irradiate microwaves. At this time, the temperature in the accommodating portion S increases and the internal air expands, but the expanding air is discharged to the outside through the check valve 10. Moreover, the bactericidal effect with respect to a foodstuff is acquired by this microwave irradiation and a heating. And after performing heat processing in this microwave oven, if it cools naturally for a fixed time, the air which remains in an accommodating part will be discharged | emitted by a pressure reduction effect | action, and an inside will be in a vacuum state. At this time, if air remains inside, the internal air can be completely discharged by pressing the housing portion S by hand.

  As described above, the storage bag 1 in a vacuum state has been sterilized by a heating process (microwave irradiation) of a microwave oven, and further, the air in the storage part has been deaerated. Therefore, the food is not spoiled, deteriorated, or changed in taste, and can be stored for a long time by storing it in a refrigerator or the like. And the foodstuff preserve | saved as mentioned above can be again heat-processed with a microwave oven, can be taken out through the opening part 8A, and can be eaten.

  The storage bag 1 according to this embodiment has a structure suitable for the above-described procedure, and can store food easily and reliably without causing spoilage, alteration, and alteration.

  As mentioned above, although embodiment of this invention has been described, this invention is not limited to above-described embodiment, In the range which does not deviate from the summary, it can implement variously. For example, the shape, the welding part, and the welding form of the sheet-like member constituting the containing bag are not limited to the above-described embodiments, and can be arbitrarily set. Further, the arrangement position and structure of the sealing means for sealing the opening of the bag main bag are not limited to those of the above-described embodiment, and can be arbitrarily set.
