Description

  The present invention relates to an improvement in a food storage and a food storage method containing a quality preservative containing a natural extract component that volatilizes a quality preservative gas.

  In recent years, many quality preservatives containing natural extract components extracted from wasabi and chili have been proposed and marketed. This kind of quality preservatives should be installed in the food storage because the natural extract components contained in the product will volatilize and the gas with insecticidal, fungicidal and fungicidal effects will be volatilized. Thus, it is possible to delay the deterioration of the quality of food in the food storage.

  As this kind of quality preservatives, for example, food quality deterioration preventing agents for refrigerators and lunch boxes, anti-mold and anti-bacterial agents for air conditioners, etc. have been commercialized. These products are wrapped in a film or the like so that they can be exchanged as cartridges, and the cartridges can be further placed in the main body container or installed in the target container or device as they are.

  By the way, the quality preservative cartridge in which such a use target is specified is effective even when used for other target containers and devices. However, when a product for a refrigerator is used for a food storage, for example, Because it is used, the natural extractant gas is volatilized in large quantities, the gas concentration in the storage becomes abnormally high, the medicinal period expires, and the product does not last long.

  When a cartridge for an air conditioner is substituted for a food storage, the volatilization is controlled by a film, but the volatilization amount increases in a large space in the storage, and the life of the quality preservative is also shortened.

  In order to solve such a problem, it can be assumed that the quality preservative cartridge is further housed in a perforated case or the like to form a double housing structure to suppress gas volatilization.

For example, Patent Document 1 discloses a gas permeable membrane made of a polyurethane-based shape memory resin on the inner bottom surface of a container for storing a natural extract antibacterial agent and provided with a vent on the bottom surface thereof. What is installed is described. In other words, this structure has a structure in which the amount of gas permeation is limited and the amount of gas released into the food storage space can be suppressed by interposing the gas permeable membrane.
JP-A-10-57029

  However, in the above document, the degree of suppression of gas permeation can be controlled by replacing the gas permeable membrane with another gas permeable material having different permeability, but the gas permeable membrane is part of the container (bottom surface). Therefore, even if the permeability of only a part of the structure is varied, the gas permeation amount per unit time can be finely adjusted. In addition, it is expected that it is difficult in terms of structure to replace the gas permeable membrane once it has been used.

  Further, in the invention of the above-mentioned document, the polyurethane-based shape memory resin used as the gas permeable membrane is a temperature-sensitive material, and as shown in FIG. The invention aims to control by temperature, and does not assume that the amount of gas emission is controlled according to the purpose of use or the period of use.

  The present invention has been proposed in view of such circumstances, and an object thereof is to provide a food storage and a food storage method capable of easily controlling the amount of quality-preserving gas released into the food storage. There is.

  Further, according to the experiment of the present inventors, when installing the quality preservation agent in the form of a cartridge in the food storage, a large amount of gas is volatilized at the initial stage of installation of the quality preservative in the food storage, After that, as time passes, it has been found that the amount of gas volatilization per unit time decreases and stabilizes due to a decrease in quality preservation components due to gas volatilization, etc. It is also included in the object of the present invention to provide a food storage method capable of adjusting the above.

  In order to achieve the above object, the food storage according to claim 1 is a food storage containing a quality preservative containing a natural extract component that volatilizes the quality preservative gas, The main body is sealed in a container with a lid made of a gas permeable material that allows the quality-preserving gas to pass through.

  The gas permeable material is a gas permeable resin.

  In Claim 3, the container with a lid is configured to vary the gas permeation amount per unit time of the quality preserving gas volatilized from the quality preservative into the food storage.

  The food storage according to claim 4 is configured to change the gas permeation amount by replacing the lid of the lidded container.

  The food storage according to claim 5 is configured such that the gas permeation amount is variable by attaching or removing the gas permeation control plate to or from the container with the lid.

  The food storage according to claim 6 is configured to change the gas permeation amount by replacing the lidded container.

  The food storage method according to claim 7, wherein the container with a lid according to any one of claims 3 to 6 is replaced and accommodated in the food storage, so that the quality storage agent is stored in the food storage at the initial use. It suppresses the gas permeation amount per unit time of the quality preserving gas that is volatilized in order to delay the quality deterioration of the food stored in the food storage.

  According to the food storage of claim 1, the quality preservative containing the natural extract component is enclosed in a container with a lid formed of a gas permeable material whose main body permeates the quality preservative gas. And since it is made into a double structure and accommodated in the storage, the permeation | transmission amount of volatility quality preservative gas can be suppressed, and it can prevent that the gas concentration in a food storage becomes high abnormally. Therefore, while preventing gas volatilization and prolonging the effective period of the quality preservative, it is possible to prevent insect pest avoidance, fungus and mold growth in the food storage.

  Further, since the quality preserving agent is accommodated in the gas permeable material container, it is not necessary to process and form the gas passage for gas release, and the manufacturing cost can be reduced.

  According to the food storage of claim 2, the gas permeable material is a gas permeable resin, has a certain molecular structure, has a structure in which gas is adsorbed to the material and gas is released from between molecules. Therefore, the gas permeation amount can be controlled according to the gas permeation amount fluctuation factors such as the gas permeation area, wall thickness, and volume of the container with a lid. Further, by using an inexpensive resin such as polypropylene as the gas permeable resin, it is possible to provide a food storage that does not require manufacturing costs.

  According to the food storage of Claim 3, since it is set as the structure which varies the gas permeation amount per unit time of the quality preservative gas volatilized in the food storage from a quality preservative according to a use aspect. In addition, the gas permeation amount that matches the purpose of use, such as the type and size of the storage, the amount and type of food contained, can be designed in advance. Moreover, even if the gas volatilization amount of the quality preservative varies with time, the gas permeation amount from the lidded container can be made constant by varying the gas permeation amount variation factor.

  According to the food storage of the fourth aspect, since the lid of the lidded container can be replaced, an appropriate one is selected from a plurality of lids having different permeability according to the use mode. Can be used to control the optimal gas permeation amount.

  According to the food storage of the fifth aspect, since the gas permeation control plate can be attached to and detached from the lidded container, the gas permeation amount can be easily controlled, and the quality preservative gas volatilization amount can be controlled. It can respond quickly to changes over time. Further, when the lidded container is a box having a plurality of planes, the gas permeation amount can be finely adjusted by adding a plurality of gas permeation control plates to the planes in combination.

  According to the food storage of the sixth aspect, since the gas permeation amount is made variable by replacing the container itself, the amount of gas released into the food storage can be easily adjusted.

  According to the food storage method according to claim 7, since the container with a lid according to any one of claims 3 to 6 is a method of replacing and storing in the food storage, at the time of initial use of the quality preservative The gas permeation amount per unit time of the quality preserving gas volatilized in the food storage can be suppressed, thereby extending the life of the quality preservative and delaying the quality deterioration of the food stored in the food storage. Can do.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 is a schematic perspective view showing an embodiment of the food storage of the present invention. FIG. 2 is a perspective view showing an open state of a lidded container installed in a food storage.

  The food storage 10 is incorporated in a kitchen cabinet (not shown) or the like, and includes a box 11 having a front opening 12 and a double-open door 13 that closes the front opening 12 so as to be openable and closable. A storage space 14 is provided. Such a food storage 10 can also be incorporated in a cup board, pantry, or the like.

  The food storage space 14 in the food storage 10 is formed as a space for storing root vegetables such as potatoes, sweet potatoes, spinach and Japanese mustard, and fresh foods such as fruits such as mandarin oranges and apples. The food storage space 14 is preferably used by stacking or arranging net cages (not shown) that can be individually stored.

  A box-shaped container 20 with a lid is disposed on the back wall 15 of the food storage space 14, and a quality preservative cartridge 1 that can be replaced and contains a natural extract component is accommodated in the container 20. Yes. In this example, the container 20 with the lid is fixed to the back wall 15 in the food storage 10, but the fixing location is not limited, and it may be placed without being fixed, or the outer surface of the container 20. May be suspended so as not to contact the storage.

  The container 20 with a lid has an opening 21a, and includes a main body 21 including four side walls 21b and a bottom 21c, and a hermetic lid 22 that is detachably fitted to the main body 21. Here, the sealing lid 22 may have a simple sealing structure. Therefore, as long as the object of the present invention can be achieved, a slight gap may be formed between the main body 21 and the main body 21. In this example, the sealing lid 22 is an engaging portion 22 a formed to project from the inner peripheral portion on the back side of the lid 22, and has a simple sealing structure that can be elastically engaged and fitted into the opening 21 a of the main body portion 21.

  At least the main body 21 of the container 20 is made of a resin such as polypropylene, polystyrene, high density polyethylene, or low density polyethylene. This resin material has a structure in which a gas containing a natural extract component volatilized from the quality preservative 1 is adsorbed and passed between resin molecules. In addition, you may use the gas permeable raw material other than the above which can permeate | transmit gas.

  In addition, the material of the lid 22 is not limited, but can be easily configured if the main body 21 and the lid 22 are made of the same material, such as commercially available Tupperware (registered trademark). .

  The quality preservative cartridge 1 contains wasabi components (wasabi oil, allyl isothiocyanate) for the purpose of maintaining quality such as insect repellent (repellency, insecticide) and sterilization, antibacterial, deodorant, mold prevention, antioxidant, freshness maintenance, Solidified solids (not shown) are stored in a perforated film, etc. If left at room temperature, the gas is volatilized (sublimated) and discharged from the cartridge for insecticidal and sterilizing. It exhibits various effects such as antibacterial, deodorant, antifungal, antioxidant, and freshness preservation.

  The horseradish extract is not limited to a solid substance, and may be a powder, a granule, or a liquid substance. Further, instead of the cartridge film with the gas discharge port, the quality preservative may be stored in a perforated case, a bag made of Japanese paper, nonwoven fabric, woven fabric, or the like.

  Furthermore, the quality preservative 1 may contain other natural extractive components in addition to or in place of the wasabi extract. For example, in addition to chili (capsaicin) and garlic (alicin), ginger, pepper, pepper, yam , Mustard, ginger, hinoki (hinokitiol), bamboo, perilla, basil, rosemary, cinnamon, banana, herb, clove, cinnamon, cardamom, nutmeg and other natural extract ingredients. It is desirable that a gas larger than the specific gravity of air is volatilized from such a quality preservative solid.

  Moreover, the quality preservative 1 may be produced | generated separately for every use and component, and you may make it mix them in a cartridge film. In addition, a preservative may be added to the quality preservative 1. Moreover, you may make the container 20 with a lid | cover store the quality preservative 1 of solid substances, such as granular form and powder form, as it is.

  Further, as the quality preservative cartridge 1, a cartridge for an air conditioner having strong antifungal and antibacterial effects corresponding to the internal environment of the air conditioner that easily generates mold may be used. In this example, “Matsushita Electric Industrial Co., Ltd., air-conditioning wasabi-proof mold pack, CZ-SW6” is used.

  Such a quality preservative cartridge 1 is attached to the inner bottom surface of the main body 21 or the back side of the lid 22 with a double-sided tape or the like as shown in FIG. It is desirable to fix.

  In this way, the quality preservative 1 is not installed in the food storage 10 as it is, but is contained in the gas permeable resin lidded container 20, and the quality preservative gas volatilized from the quality preservative 1 is used as the lidded container 20. Since the structure is such that the molecules of the resin material permeate through and are released to the outside, the amount of gas released to the food storage space 14 can be suppressed.

  Therefore, even if the quality preservative cartridge 1 for an air conditioner having a strong effect as in this example is used as a quality preservation agent for the food storage 10, a gas dilution effect due to permeation between resin molecules causes a unit per unit time. The amount of gas permeation is suppressed and the gas concentration in the food storage is prevented from becoming abnormally high. Therefore, the medicinal preservative period of the quality preservative 1 can be prolonged, and the quality preservative 1 can be prolonged.

  Further, since the gas permeable material has a certain molecular structure and is made of a gas permeable resin that allows gas to be adsorbed to the material and allows gas to pass between the molecules, the gas permeation amount can be adjusted without variation. Furthermore, by using an inexpensive resin such as polypropylene as the gas permeable resin, it is possible to provide a food storage that does not require manufacturing costs.

  The amount of gas permeation and emission per unit time from the inside of the resin container varies depending on factors such as the contact area (gas permeation area), volume, and thickness of the lidded container 20 with the food storage space 14. Therefore, by changing the gas permeation amount variation factor of the lidded container 20, the gas permeation amount is a value corresponding to the purpose of use or period of use, such as the type, size, amount of food stored, type, etc. Can be adjusted.

  For example, in the example of FIGS. 1 and 2, the bottom portion 21 c of the container 20 with the lid is fixed to the back wall 15 in the food storage 10 and gas permeation from the bottom portion 21 c is prohibited. If the side surface is installed so as to be fixed to a wall surface or the like in the storage 10, the contact area with the food storage space 14 is increased, so that the amount of gas per unit time increases. That is, even when the same kind of quality preservative is installed in the food storage 10 having different volumes of the food storage space 14, the installation mode of the lidded container 20 may be made different depending on the volume of the food storage space. The gas permeation amount can be adjusted almost the same between the food storages.

  In this way, by adjusting the gas permeation amount fluctuation factors such as the gas permeation area of the lidded container 20, the amount of gas released in the food storage 10 can be suppressed. Even when the quality preservative 1 having a large volatilization amount is used, the amount of gas released can be set to an appropriate amount commensurate with the food storage.

  Moreover, it is known that the commercially available quality preservative 1 used in this example has a large amount of gas volatilization per unit time at the initial stage when the product package is opened and the use is started, and then decreases. However, even when the quality preservative 1 in which the gas volatilization amount fluctuates with time is used as described above, by changing the gas permeation amount fluctuation factor of the lidded container 20 over time, The amount of gas emission can be made constant by suppressing such fluctuations. Therefore, wasteful use of the quality preserving agent 1 in the initial stage of installation can be prevented, the quality preserving agent 1 lasts longer, and the quality retention period of the food in the food storage 10 with one cartridge can be extended.

  The quality-preserving gas having a specific gravity greater than that of air and containing a natural extract component shown in this example accumulates from the lower part of the food storage space 14 of the food storage 10 to the upper part, so that the air Ethylene gas, which is a mature hormone generated from root vegetables and fruits having a low specific gravity, is pushed upward, and as a result, such ethylene gas is above the door 13 formed in the opening 12 of the food storage 10. It is discharged from a gap (not shown).

  In addition, if the structure is airtight except for a part above the opening 12, the quality preserving gas heavier than air does not leak to the outside and accumulates in the lower part of the food storage space 14, so that the quality preserving effect is obtained. It can be further sustained.

  3 to 5 are diagrams showing three typical modes in which the gas emission amount per unit time is varied by adjusting the gas permeation amount variation factor.

  FIG. 3 is a diagram for explaining a mode in which the gas permeation amount is changed by replacing the lid 22 of the container 20 with the lid. FIGS. 3A to 3C show the lids with different shapes as viewed from the back side. It is a perspective view. FIGS. 3B and 3C are examples in which the lid is provided with a height so that gas can be transmitted from the side surface.

  By appropriately using such a lid 22 according to the purpose of use and the period of use, the contact area with the food storage space 14 (see FIG. 1) can be adjusted, and the amount of gas released into the food storage space 14 can be varied. .

  For example, at the initial stage of installation in the food storage 10, the quality preservative 1 has a large gas volatilization amount, and the gas permeation amount per unit time is reduced by using the lid 22 having a small surface area shown in FIG. Then, when the gas volatilization amount is reduced, the gas discharge amount to the food storage space can be made constant by replacing the lid 22 with a large surface area such as FIGS. 3B and 3C. Moreover, since it is the structure which replaces the lid | cover 22, you may use it in the state which the main-body part 21 was made to adhere in the food storage compartment 10. FIG.

  The replacement mode is not limited to the method of changing the surface area size of the lid 22 as shown in FIG. 3, and a method of changing the gas permeation degree by changing the material can be adopted. Further, a lid (not shown) having an opening may be used.

  FIG. 4 is a view for explaining a method of changing the gas permeation amount by attaching and removing the gas permeation control plate 25 to the container 20 with the lid. In the figure, the illustration of the lid is omitted.

  As shown in the figure, the lidded container 20 has a plate insertion portion 23 formed on the inner side of one of the four side walls 21b of the body portion 21 of the container 20, and a gas permeation control plate is formed in the insertion portion 23. By inserting 25, the side wall 21b is closed and the gas permeation of the whole container is suppressed. In addition, it is possible to use a shielding plate that does not allow gas permeation as the gas permeation control plate and completely block gas permeation from the side wall 21b, or use a gas permeation plate as the gas permeation control plate, That is, the gas permeation amount from the side wall may be reduced by overlapping the gas permeable plates.

  4 illustrates the structure in which the gas permeation control plate 25 is added only to one side wall 21b, but the gas permeation control plate 25 can be added to any of the four side walls 21b, the lid 22, and the bottom 21c. Good. By combining a plurality of gas permeation control plates 25 in this way, it is possible to finely adjust the gas permeation amount per unit time.

  In addition, the quality preserving agent is used to prevent the gas from leaking in the gas permeation control plate made of an inner lid (not shown) such as a drop lid made of a gas non-permeable material, etc., instead of the structure for closing the side wall 21b as shown in the figure. The gas permeation from the lid 22 may be suppressed by dropping it from above. Further, such a gas permeation control plate may have a structure in which a plurality of gas permeation control plates are prepared in advance as the inner lid of the container, and the number of sheets to be overlapped is changed according to the period of use and the purpose of use.

  Further, the gas permeation control plate 25 may be attached to the outer surface, for example, a tape-like control plate may be attached.

  With such a configuration, the gas permeation per unit time can be obtained by adding the gas permeation control plate 25 at the initial stage of installation in the food storage 10 (see FIG. 1) at the stage where the gas volatilization amount of the quality preservative 1 is large. The amount of gas released to the food storage space 14 (see FIG. 1) can be made constant by removing the gas permeation control plate 25 when the amount is reduced and then the gas volatilization amount is reduced.

  Further, in the illustrated example, since the lidded container 20 is a box having a plurality of planes, the gas permeation amount can be finely adjusted by adding a combination of a plurality of gas permeation control plates 25.

  FIG. 5 is a view for explaining a method of changing the gas permeation amount by replacing the lidded container 20.

  That is, as shown in FIG. 5, a plurality of lidded containers 20 having the same material and different sizes (volumes, surface areas) are prepared, and in the initial stage of installation in the food storage 10 (see FIG. 1) The container 20 with a small lid is used to suppress the gas permeation amount per unit time, and after that, when the gas volatilization amount is reduced, the quality storage agent is replaced with a large-sized container 20, thereby providing the food storage space 14. (See FIG. 1) The gas discharge amount can be made constant.

  Further, the gas permeation amount per unit time may be varied by changing the thickness and material of the lidded container 20.

  Thus, since the container 20 itself is replaced and the gas permeation amount is made variable, it is suitable for use in a kitchen such as a hotel or restaurant equipped with various food storage units having different sizes and uses.

  According to the structure shown above, all have a structure in which the gas permeation amount per unit time of the quality preserving gas volatilized from the quality preservative 1 into the food storage is varied according to the use mode. In addition, the gas permeation amount that matches the purpose of use, such as the type and size of the food storage, the amount and type of food stored, can be designed in advance.

  Further, according to the above example, various gas permeation amount adjusting methods can be realized, but by combining these aspects, further fine adjustment of the gas permeation amount per unit time can be performed. For example, when the lidded container 20 is installed in the four food storages 10 having different capacities, the highest capacity one is hung and the second largest one is installed so that the bottom is fixed in the storage. In the third case, the bottom surface is fixed in the storage, and one side wall is closed with the gas permeation control plate 25. In the case of the smallest capacity, the bottom is fixed in the storage. And the two side walls may be closed by the gas permeation control plate 25.

  FIG. 6 is a perspective view of a food storage with rice bran inside.

  This rice bran built-in food storage 30 is incorporated in a kitchen cabinet or the like, and includes a box 31 having a front opening 32 and a double-opening door 33 that closes the front opening 32 so as to be opened and closed. A storage space 36 is formed inside the box 31. In the illustrated example, the food storage 30 is formed integrally with a drawer portion 37 provided on the upper side of the storage space 36. Such a food storage 30 can be incorporated in a cup board, pantry, or the like.

  A rice bran 50 is detachably disposed in the storage space 36 of the food storage 30, and a side space of the rice bran 50 through the partition wall 40 is formed as a food storage unit 34. Moreover, as shown in the drawing, the partition wall 40 is formed low so that the gas can sufficiently flow between the rice bran 50 and the food storage unit 34.

  The food storage unit 34 is formed as a space for storing fresh vegetables such as root vegetables such as potatoes, sweet potatoes, spinach and komatsuna, and fruits such as mandarin oranges and apples, and a wire rack for directly placing these foods. 41 is installed across the partition wall 40 and the side wall so that a space is formed below it, and a mud receiving tray 42 is installed in the lower space so as to be freely inserted and removed.

  Of the edges on the front opening 32 side, band-shaped packing materials 43 for closing gaps formed when the double-open doors 33 are closed are attached to both edge edges and lower edge edges. That is, when the front opening 36 is closed by the opening door 33, the gap formed at both side edge portions and the lower edge portion of the front opening 36 is closed by the packing material 43. Note that no packing material 43 is attached to the upper end of the opening 32, and a slight gap is formed even when the opening door 33 is closed.

  The double-open door 33 includes a left door body 33 on the rice bran 50 side and a right door body 33 on the food storage section 34 side, and a band-shaped packing material 43 is attached to the open end of the right door body 33. ing. This packing material 43 is formed by fixing a packing made of a flexible resin or the like on the surface of a belt-like plate material, and is pivotally fixed to an open end portion of the right door body 33 together with a spring material (not shown). The structure is biased in the direction of rotation toward the open end side of the body 33.

  On the other hand, the rice bran 50 is formed in a box and is housed in a storage space so that it can be slid in and out of the rail 39, and a rice loading slot provided with an upper lid 51 with a handle 52 on the top surface of the box. 53, a rice storage space 54 is formed below the rice inlet 53, and a rice receiver 55 is provided below the rice storage space 54. Further, the front side of the rice bran 50 is provided with an operation unit 56 capable of taking out rice in a meterable manner and a window 57 for visually confirming the amount of rice stored in the rice storage space 54. The perspective view shown in FIG. 6 shows a state in which the rice bran 50 is pulled out.

  Further, in each of the rice storage space 54 and the food storage part 34 of the rice bran 50, containers 20 and 20 with lids made of a gas permeable material containing the quality preservative cartridge 1 containing a natural extract component are installed. . In the illustrated example, the lidded containers 20, 20 are attached to the upper side of the rear wall 57 of the rice storage space 54 and the back wall 35 of the food storage unit 34.

  Thus, since the quality preservative 1 is enclosed in the container 20 with a lid and the container 20 is installed in the rice bran 50 and the food storage unit 34, the quality preservability in the rice bran 50 and the food storage unit 34 is maintained. While controlling the amount of gas released, it is possible to prevent pest repellent, fungus and mold growth in the food storage 34.

  An opening may be provided in the upper lid 51 of the rice bran 50 so that each quality preserving gas is circulated between the rice storage space 54 and the food storage 34.

  In addition, it is generally known that in the food storage, ethylene gas, a mature hormone, is generated from root vegetables and fruits, and this ethylene gas accelerates the softening and decay of root vegetables and fruits themselves. In the structure shown in FIG. 6, since the lower part has an airtight structure with the packing material 43 in the food storage part 34, the gas released from the container 20 accumulates from the lower part to the upper part. As a result, ethylene gas having a specific gravity smaller than that of air is gradually driven upward, and is discharged from the exhaust opening window 38 and the upper gap, and water vapor and odor are also discharged.

It is a schematic perspective view which shows one Embodiment of the food storage warehouse of this invention.
