Description

  The present invention relates to a refrigerator provided with an antioxidant having an antioxidant effect, and a storage container for storing an antioxidant having an antioxidant effect.

  Conventionally, for example, Japanese Patent Application Laid-Open No. 2000-180034, Japanese Patent Application Laid-Open No. 10-23894, and the like have been disclosed as techniques for maintaining the freshness of vegetables and the like. In the former, a fresh antibacterial substance in which an aromatic substance having a freshening action is incorporated into an antibacterial agent having a volatile antibacterial component is incorporated in a cassette, and this is inserted into a rib molded into a vegetable container from above and attached. The content which makes it easy to replace the attachment / detachment of the freshness maintaining device is disclosed. The latter discloses the content of maintaining freshness by breathing and oxidatively decomposing ethylene gas generated by the respiratory action of vegetables and fruits stored in a refrigerator or the like, or a bad odor caused by the progress of decay.

JP 2000-180034 A Japanese Patent Laid-Open No. 10-23894

  According to the explanation of the former technique, the antibacterial agent and fragrance substance are kneaded, and by having a plurality of ventilation holes, the antibacterial components can be diffused and released smoothly, and the AIT antibacterial is a heavy volatile material with a high specific gravity that has a particularly high preservation effect. It is said that discoloration of fruits and vegetables can be avoided by gradually releasing and diffusing the agent from the top.

  The conventional suppression of such generated gases and the preservation of antibacterial components adhere to the effect of keeping the food, but the essence is only the effect of delaying spoilage by suppressing the growth of bacteria attached to the surface. There is a problem that the freshness is passively maintained and nutritional components contained in the food are not retained. Further, as a technique similar to the conventional technique, as described in JP-A-7-174455, ethylene gas generated from fruits and vegetables is brought into metallic contact with a catalyst to be combined with oxygen to make a food storage atmosphere low in oxygen. In addition, there are those that absorb oxygen in the food environment, as disclosed in JP-A-10-160328 and JP-A-56-17633. There was a problem that it was not practical because it could not solve the problem of life, because it improved the surrounding environment and indirectly suppressed the decrease in freshness.

  In addition, as a method of disposing volatile antibacterial components in a refrigerator, there is a method of kneading into a substrate, but this method has a problem that internal components are not released when the substrate surface is dried and solidified. It was. There is also a method of arranging microencapsulated and cyclodextrin-containing powder in the cold air channel, but when the components in the powder on the surface are released, the internal components are released due to the residue blocking the ventilation. There was a problem that the speed became slow.

  In addition, there is a method of carrying and arranging on a fiber, but this method has a problem that a carrier is missing and a shape is difficult to fix. As a result, there is a problem in that it is important to study the structure of how easily it can be replaced as described in Japanese Patent Laid-Open No. 2000-180034. It was. For this reason, in the case of a vegetable container divided into two or more in the conventional method, it is necessary to arrange an antibacterial agent in each compartment, which causes a cost increase, and further considering replacement, There were problems such as restrictions on the mounting structure.

  In particular, in the mounting structure described in Japanese Patent Application Laid-Open No. 2000-180034, since the antibacterial cassette is inserted into the rib molded into the vegetable container from the upper part and attached, it can be fixed only to a specific place of the vegetable container. When the cassette was not used, the storage capacity of the vegetable container was reduced by the rib structure, which hindered the preservation of vegetables and was poorly cleaned.

  In addition, allylisoxocyanate, which is a volatile antibacterial component having a high freshening effect in Japanese Patent Application Laid-Open No. 2000-180034, is a flammable substance of a hazardous material type 4 and type 2 petroleum. This is a problem such as when there is a risk of burning by depending on the temperature when it is in a closed space such as a refrigerator, even if the amount of use per refrigerator is small, such as a warehouse Sufficient care was required in storage and production, and there were problems such as a risk of flammable explosion. Especially in refrigerators that use flammable natural refrigerants such as hydrocarbons, complex problems such as the need for further safety measures for combustion occur.

  The present invention has been made to solve the above-described problems, and is a refrigerator and an antioxidant storage container that work directly on food to enhance the effect of retaining the ingredients such as nutrition inherent to the food. I will provide a. Furthermore, this invention provides the refrigerator and the storage container for antioxidant which do not reduce not only what maintains nutrition, such as vitamin C which a foodstuff holds, but. Furthermore, it aims at providing the refrigerator of the structure arrange | positioned so that a volatile antioxidant component may spread over in a storage chamber. It is another object of the present invention to provide a detachable antioxidant storage container that is easy to handle and can be used conveniently.

  The refrigerator of the present invention is a refrigerator having a storage room for storing food, a lower container installed in the storage room, and an upper container installed on the upper part of the lower container in the storage room. A storage part for storing the antioxidant incorporated in the packaging container so as to be released to the outside, an opening provided in the storage part for releasing a volatile component of the antioxidant, and hooked and fixed in the storage chamber An anti-oxidant storage container having a hook portion, and the length of the upper container in the depth direction is such that the upper container does not get in the way even when vegetables and the like are stood in front of the lower container. It is set shorter than the lower container, and the antioxidant container is hooked and fixed inside the front wall of the upper container.

  In the refrigerator of the present invention, the antioxidant storage container can be easily attached to all the storage rooms in the refrigerator, and the user can replace the antioxidant packaging container containing the antioxidant by himself.

  Although the refrigerator of the present invention has a simple configuration, it can be filled with an antioxidant in the storage chamber, and can be used to keep foods antioxidant and maintain freshness.

In the refrigerator of the present invention, the antioxidant storage container does not disturb the vegetables stored in the standing container. Further, not only the upper container but also the lower container is filled with antioxidant components. Therefore, the freshness maintenance by the antioxidant of the whole vegetable room and the reduction | decrease of vitamin C can be suppressed.

  The refrigerator of the present invention can inexpensively fill other compartments with antioxidants, and can suppress antioxidant and vitamin C lowering.

  The refrigerator of the present invention can prevent the powdered antioxidant from flowing out of the antioxidant storage container by the fitting portion by the rib portion even if the packaging material of the antioxidant packaging container is damaged. .

  Since the refrigerator according to the present invention includes the cover portion for preventing the antioxidant from falling, which is provided in the first opening portion of the storage portion so as to block a part of the first opening portion. It is possible to prevent the antioxidant from flowing out of the antioxidant container. In addition, since the antioxidant can be fixed when assembling the antioxidant container, even if the strength of the packaging material is weak, it can be stored in the cover on the bag and assembled stably. be able to.

Embodiment 1 FIG.
FIG. 1 is a cross-sectional view of an antioxidant packaging container for a refrigerator representing Embodiment 1 of the present invention, and FIG. 2 shows changes in vitamin C of broccoli in an antioxidant atmosphere showing an example of the effect of the enclosed antioxidant. FIG. In FIG. 1, 3 is an anti-oxidant packaging container that can maintain hermeticity and can release the anti-oxidant 3a, 2 is a narrow hole that is an opening formed in the anti-oxidant packaging container 3, and 40 is an antioxidant. It is a non-woven fabric attached so as to close the fine hole 2 which is an opening provided in the packaging container 3 from the outside or the inside, and the granular antioxidant 3a is retained in the antioxidant packaging container 3 and also has a volatile component. Can be released to the outside.

  Since it is configured as described above, the antioxidant 3a volatile component enclosed in the antioxidant packaging container 3 is released to the outside through the narrow hole 2. At this time, the eucalyptus extract or the rosemary extract or a mixture of both is enclosed as an antioxidant, so that the vitamin C component in the vegetable is retained in this antioxidant atmosphere as shown in the test results of FIG. The 1 is made of plastic, and the narrow hole 2 that is an opening is provided in a dimension and a direction in which the granular antioxidant 3a does not pop out.

  When the granular antioxidant 3a receives an external force such as impact or vibration from the outside, the granular antioxidant 3a is displaced or moved in the packaging container 3, and the particles facing the narrow hole 2 as the opening are replaced. In the case of using a bare antioxidant as shown in FIG. 1, the narrow hole 2 of the packaging container 3 may be made smaller according to the size of the built-in grains. In the case of covering with a particle smaller than the size of the particle, even if the narrow hole 2 of the packaging container 3 is large, it is convenient that the particle does not jump out due to external force. Although the packaging container 3 in FIG. 1 is made of plastic, the whole may be formed into a bag shape as a non-woven fabric 40 so that the volatile component of the antioxidant 3a can permeate through the gap around the whole. In this case, when the bag is deformed upon receiving an impact, the antioxidant in the bag flows to cause replacement of particles close to the surface and particles close to the center of the bag, and the antioxidant 3a is easily volatilized, which is convenient.

  The mechanism of vitamin C change shown in FIG. 2 will be described. Some nutritional components contained in vegetables are bound to oxygen in the air and decompose and decrease (ie, the components are oxidized). When having an antioxidant as in the present embodiment, the presence of an antioxidant component on the surface of the vegetable causes the oxygen in the air to disappear in conjunction with the antioxidant component before reaching the vegetable. Nutritional components in vegetables are not oxidatively decomposed.

  FIG. 2 shows the effect of such an antioxidant. By storing eucalyptus and rosemary and storing broccoli, the decrease in vitamin C in broccoli is suppressed as compared with the case where no antioxidant is present. Eucalyptus and rosemary are representative of such antioxidant substances. Eucalyptol (1.8 cineole), an antioxidant component contained in eucalyptus and rosemary, is also included. ), A substance containing a large amount of α-pinene, nearuri camphor white, marjoram spanish and the like.

Other high molecular weight antioxidants include, for example, enzymes such as SOD, catalase, glutathione, glucose phosphate, peroxidase, dehydrogenase, and low molecular weight low molecular weight antioxidants such as vitamin E. , C, B ₂ , catechins and other polyphenols, flavonoids, tannins, carotene and the like. Moreover, although it demonstrated in the particulate form in FIG. 1, what is necessary is just to be incorporated in the packaging container 3 in the state which can be liquid and all can flow.

  In the data of FIG. 2, the amount of vitamin C in broccoli in the antioxidant atmosphere has increased to about 120 percent on the first 2-3 days. This is because the vegetables are alive after harvesting and increase vitamin C, but traditionally, for example, even if the surroundings are in a low oxygen state, the vegetables are oxidized and vitamin C decreases, rather than increases. It was more likely to decrease, and it was always thought that nutrition would decrease.

  However, when the volatile component of the antioxidant as in this embodiment is directly applied to vegetables, data indicating that oxidation, that is, a decrease in vitamins is suppressed and vitamin C increases is obtained. This is because the increased amount is larger than the decreased amount of vitamin C, and as a result, an increase in vitamin C is obtained. Plants have taken nutrients from the soil, but after harvesting, they use their body components to live. At this time, freshness can be maintained by suppressing a respiratory action that consumes components in the body.

  As effective for maintaining freshness, it is effective to lower the temperature for respiratory control, and it is also effective to increase the humidity as a measure against drying. However, in the present invention, in order to maintain nutritionally and be in a direction that may be delicious, especially for vitamin C that deteriorates due to oxygen on the vegetable surface, the volatile component of the antioxidant is satisfied and the nutrition is increased as well. It also makes it possible. In addition, the temperature of vegetables may be further lowered to that of the present invention to further suppress the decrease in vitamin C. When stored at 0 ° C. for a long time, vegetables change the components in the body according to the environment, increasing the amino acid content and increasing the taste.

Each storage room (refrigeration room 200, switching room 300, ice making room 400, vegetable room 500, freezer room 600, etc.) in the refrigerator main body 100 has at least one width part having such a width that the hook part 4 can be hooked. Has more than one place.

  In the present embodiment, the width dimension of the width portion is set to a dimension of L2 or more and L1 or less so that the antioxidant storage container 1 can be placed anywhere in each storage room in the refrigerator main body 100. Conversely, the L1 and L2 dimensions of the hook portion 4 may be determined in accordance with the range of the width dimension of the portion where the hook portion 4 is desired to be hooked in each storage chamber. That is, if the minimum width dimension of the width portion is A and the maximum width dimension is B, L1> B and L2 <A may be satisfied. By determining the L1 and L2 dimensions of the hook portion 4 in this way, the antioxidant container 1 can be placed in any storage room, so that the volatile components of the antioxidant for any food in the storage room Since it works directly, the effect of maintaining freshness is great, such as suppressing the decrease in vitamin C.

  In FIG. 6, 9 is an upper container in the vegetable compartment 500, 1 is an antioxidant storage container, and 4 is a hook portion provided in the antioxidant storage container 1. As shown in the figure, when the side wall of the upper container 9 is inclined (inclination angle X) due to a draft angle or the like, the attachment angle X1 of the antioxidant storage container 1 may be also inclined. (An angle X1 may be substantially equal to the angle X.)

  Here, the angle X1 can be adapted to the shape of the container by making it substantially equal to the draft X degree generated when the upper container 9 for installing the antioxidant container 1 is formed. It can be firmly fixed to the walls and doors of storage rooms. Further, the width L1 of the hook portion 4 is about 5 mm to 15 mm, and the hook portion 4 can be hooked and fixed as long as it is a container or a wall surface or door of a storage room that is within this range.

Yes.

  Here, the hole 17 has substantially the same shape as the narrow width portion 1b, and the size of the hole 17 is slightly larger than the size of the narrow width portion 1b, and the narrow width portion of the antioxidant container 1 is placed in the hole 17. Although 1b can be inserted, it does not rattle. In this way, the antioxidant storage container 1 can be installed even in a container in which the wall surface of the container is thick and the hook part 4 cannot be hooked directly.

  In the present embodiment, the method of attaching the antioxidant storage container 1 has been described by taking the upper container 9 of the vegetable room 500 as an example, but the container of another storage room, for example, provided in the lower part of the refrigerating room 200 shown in FIG. The slide chamber case installed in the slide chamber 700, the ice storage box installed in the ice making chamber 300, the switching chamber container installed in the switching chamber 400, and the vegetables installed in the vegetable chamber 500 are stored upright. Even if the antioxidant container 1 is hooked or inserted on a vegetable stand or the like for installation, the same effect can be obtained. Further, in this embodiment, the hook 4 is provided in the antioxidant storage container 1, so that even if it is not the above-mentioned manufacturer's genuine case or container provided as an accessory in each storage room, the user can uniquely Can be installed in cases and containers that are purchased and used for organizing, etc., so that it is possible to obtain an antioxidant storage container and a refrigerator with a high degree of freedom in installation location.

  Moreover, you may attach to the shelf of a refrigerator as shown in FIG. FIG. 8 is a side sectional view of a storage room such as a refrigerator room of the refrigerator representing the present embodiment. In the figure, the same parts as those in FIGS. In the figure, reference numeral 200 denotes a refrigerating room as a storage room, and a plurality of shelves 18 are installed in the refrigerating room 200. In the present embodiment, with respect to the shelf 18, the antioxidant storage container 1 is placed sideways, and the hook portion 4 is installed on the shelf 18. Here, the arrow indicates the direction in which the antioxidant 3a goes out. In this case, the same effect can be obtained regardless of whether the antioxidant container 1 is installed on the shelf 18 or below. In particular, when installed under the shelf 18, it does not interfere with the food, making it easier to use. Also, the volatile component of the antioxidant 3 a is easily diffused by its own weight as shown by the arrow, and has an antioxidant effect. growing.

  FIG. 9 is a diagram illustrating a method of filling the storage chamber with the antioxidant component that is slowly released from the antioxidant container 1 containing the granular antioxidant 3a according to the present embodiment, and FIG. It is a figure showing ZZ cross section. 1 to 8 are denoted by the same reference numerals, and description thereof is omitted. In FIG. 9, reference numeral 8 denotes a lower container disposed in a vegetable room 500 serving as a storage room, and reference numeral 9 denotes an upper container disposed in the vegetable room 500 serving as a storage room and disposed above the lower container 8.

  8a is a standing container for storing vegetables and the like standing upright, and the upper container 9 is set to have a depth in the depth direction shorter than that of the lower container 8 by the depth of the standing container 8a. Even if the vegetables are stood up with the door of 500 closed, the upper container 9 does not interfere with the vegetables. In the present embodiment, the antioxidant container 1 is arranged on the front wall (front wall) of the upper container 9 so as not to obstruct the vegetables stored in the standing container 8a. The hook 4 of the antioxidant container 1 is hooked on the front wall of the upper container 9 and is fixedly arranged.

  In FIG. 10, 9 a is a protrusion provided on the inner wall of the upper container 9, and prevents the antioxidant storage container 1 from rattling by fixing the antioxidant storage container 1 so as to contact. . Further, the antioxidant container 1 is provided with holes 20a and 20b, and the upper container 9 has a hole 19 at a portion facing the hole 20b of the antioxidant container 1 on the wall surface. Moreover, the arrow in a figure has shown the direction from which the antioxidant 3a goes out (it is spread | diffused and is sustained-released).

  With such a structure, the components of the volatile antioxidant 3 a stored in the antioxidant storage container 1 disposed in the upper container 9 are contained in the upper container 9 from the hole 20 a of the antioxidant storage container 1. Furthermore, the antioxidant component comes out from the hole 20b of the antioxidant container 1 through the hole 19 on the wall surface into the lower container 8, and is heavier than air (because of its large specific gravity), so that the antioxidant component falls from above to below. However, it also flows into the lower container 8 in the vegetable compartment 500, and not only the upper container 9 but also the lower container 8 is filled with antioxidant components. Therefore, the freshness maintenance by the antioxidant of the whole vegetable room 500 and the reduction | decrease of vitamin C can be suppressed.

  Here, in order to more effectively diffuse the antioxidant component into the storage chamber, a fan device or the like may be arranged to forcibly diffuse the antioxidant component into the storage chamber. In addition, the temperature distribution in the storage chamber is partially changed to cause natural convection to diffuse by convection, or by providing a cold air outlet and suction port in the storage chamber to cause cold air convection and diffuse antioxidant components You may make it.

Embodiment 2. FIG.
FIG. 11 is an enlarged view of an antioxidant storage container mounting portion of the refrigerator representing the second embodiment. In the figure, parts equivalent to those in FIGS. 1 to 10 are denoted by the same reference numerals and description thereof is omitted. In FIG. 11, 8 is a lower container disposed in the vegetable room 500 serving as a storage room, and 9 is an upper container disposed in the vegetable room 500 serving as a storage room and disposed above the lower container 8. The upper container 9 is provided with a hole 21 on the bottom surface, and the lower part of the antioxidant container 1 passes through the hole 21 on the bottom surface and protrudes into the lower container 8. Moreover, the arrow in a figure has shown the direction from which the antioxidant 3a goes out (it is spread | diffused and is sustained-released).

  A hole 22a is provided in the protruding portion 22 protruding from the lower container 8 in the antioxidant storage container 1, and the volatile antioxidant component of the antioxidant 3a passes through the hole 22a as shown by an arrow in FIG. It is intended to be released slowly through. With such a structure, since the antioxidant component is heavier than air (having a large specific gravity), the lower container 8 can be sufficiently filled with the antioxidant component, and the maintenance of freshness and the reduction of vitamin C can be suppressed.

Embodiment 3 FIG.
In the first embodiment or the second embodiment, the method of installing the antioxidant container 1 for efficiently releasing the antioxidant component has been described. However, in the present embodiment, the first embodiment or the second embodiment is described. The structure of the antioxidant container used in the above and the method of sealing the antioxidant in the antioxidant container will be described. FIG. 12 is a view for explaining the structure of the antioxidant container, FIG. 12 (a) is a front view of the state in which the antioxidant container 1 is opened, and FIG. 12 (b) is an antioxidant container. It is a state side view in which 1 was opened. In the figure, the same parts as those in FIGS.

  Reference numeral 1 denotes an antioxidant container, 1f is a container part, and 1g is a lid part. The container part 1f and the lid part 1g are bent at the central mirror hinge part 23 to form the antioxidant container 1. Reference numeral 1c denotes an antioxidant storage portion provided in the container portion 1f, in which an antioxidant 3a such as rosemary is stored in a state of being packaged in the packaging container 3. By providing the mirror hinge 23, it is possible to configure the antioxidant storage container 1 with one component, and when the antioxidant effect of the antioxidant 3a in the antioxidant storage container 1 is lost, Even a user can easily replace only the antioxidant packaging container 3.

  The antioxidant 3a is packaged in a packaging container 3 of a packaging material such that the permeability of the antioxidant component is about 2 mg / sec · cm 2 or less at 30 ° C. Since the antioxidant 3a packaged by this packaging material does not allow the granular component or the powdery component to permeate, the granular component or the powdery component is prevented from coming out of the antioxidant container 1. About the numerical value of the standard of permeability, since it is difficult to measure in a low temperature state of a storage room such as the vegetable room 500 of the refrigerator, the numerical value at 30 ° C. represents the permeability. The permeability varies depending on the type of the antioxidant 3a, but when the antioxidant is rosemary, the packaging material may be selected based on the above permeability.

  Further, the above permeability is at a level where moisture enters and exits but water does not enter as a liquid. In addition, when the antioxidant 3a is not released slowly, such as when the antioxidant 3a is settled (hardened) in the environment of use, a desiccant such as silica gel is enclosed in the antioxidant storage container 1 together with the antioxidant 3a. Thus, the moisture that has entered the packaging container 3 may be removed. In the present embodiment, the first embodiment, and the second embodiment, as the antioxidant 3a, an antioxidant 3a such as a eucalyptus extract, a rosemary extract, or a mixture of both is encapsulated.

  Here, the container portion 1 f of the antioxidant storage container 1 is provided with ribs 24 around the antioxidant storage portion 1 c for storing the antioxidant packaging container 3, so that the lid of the antioxidant storage container 1 is covered. When the portion 1g is closed, the rib 24 enters the inside of the lid portion 1g so that the antioxidant packaging container 3 does not protrude outside the antioxidant storage container 1. Therefore, even if the antioxidant storage container 1 is closed and the hook portion 4 is hooked and used as shown in FIGS. 6 and 8, the packaging material of the antioxidant packaging container 3 is damaged. The powdered antioxidant 3 a is prevented from flowing out of the antioxidant container 1 by the fitting portion formed by the rib portion 24.

  13 and 14 are diagrams for explaining another structure of the antioxidant container. In the figure, the same parts as those in FIGS. As shown in FIG. 13, the lid 1g is closed to the container 1f, the antioxidant container 1 is assembled, and the hook 4 is hooked on the wall or the like so as to cover a part below the opening of the container 1c. A cover portion 25 is provided. In the present embodiment, the cover portion 25 is provided so that the lower portion of the opening of the storage portion 1c is formed in a bag shape, and the cover for the antioxidant storage container 1 is hooked by the hook portion 4, Even if the portion 1g is opened, the antioxidant packaging container 3 is prevented from falling.

  Therefore, the cover portion 25 configured in a bag shape is provided in the opening of the storage portion 1c of the container portion 1f, and the antioxidant is packaged in the packaging container 3 of the packaging material whose permeability is defined to a predetermined value. If the antioxidant container 1 into which the agent 3a is inserted is fixed to the wall surface or the bottom surface by the hook 4 or the like, it is possible to prevent the antioxidant 3a from flowing out of the antioxidant container 1. Further, since the antioxidant 3a can be fixed when the antioxidant storage container 1 is assembled, even if the strength of the packaging material is weak, it can be accommodated in the cover portion on the bag and is stable. Can be assembled.

  Further, in FIGS. 12 and 13, the antioxidant container 1 is connected by the mirror hinge part 23 as an opening / closing method of the container part 1f and the lid part 1g. However, as shown in FIG. It is good also as a fitting system (combination system of 2 components structure). In this case, the container portion 1f and the lid portion 1g are configured as separate parts, and a claw portion 26a is provided on one component (for example, the lid portion 1g), and the claw portion 26a is fitted on the other component (for example, the container portion 1f). The anti-oxidant storage container 1 is configured by providing a claw receiving portion 26b to be mated and fitting the claw portion 26a and the claw receiving portion 26b. At this time, if the holding structure of the internal antioxidant packaging container 3 has the same structure as that of FIGS. 12 and 13 using the mirror hinge 23, the antioxidant packaging container 3 can be moved out of the antioxidant storage container 1. Prevents leakage. Further, since the antioxidant packaging container 3 can be fixed when the antioxidant storage container 1 is assembled, even a material whose strength of the packaging material is weak is accommodated in the bag-shaped cover 25. Can be assembled stably.

  In the above embodiment, the permeability is controlled by the packaging material in which the antioxidant 3a is encapsulated, but it is controlled by the opening areas of the holes 20a and 20b of the outer antioxidant storage container 1. Also good. In other words, in the above example, the permeability of the antioxidant container 1 is made larger than the permeability of the packaging material, but if it is reversed, the antioxidant container 1 can be controlled. For example, when installed in a refrigerator-freezer with different capacity of vegetable containers, the number and area of the holes 20a and 20b of the antioxidant container 1 are changed, or the amount of discharge is controlled by the area of the holes 19 of the upper container 9 By doing so, it can handle cases of various capacities. Furthermore, in the case of a refrigerator in which the amount of vegetables to be stored varies depending on the household, the discharge amount can be controlled by closing or opening the holes 20a and 20b of the antioxidant storage container 1 with a tape or the like.
