Sealed type historical material storage bag

Abstract

To solve the problem that, in a conventional hermetically sealed storage bag, since the opening is in one place, taking in and taking out storage materials and replacing a deoxidation agent and a humidity regulator are carried out in the same opening, thereby a fixing tool for hermetically sealing becomes larger according to the size of the storage bag, and work for hermetically sealing is hard to be done, and also when the work for hermetically sealing is done with a heat seal, the bag needs to be cut and opened for checking the materials inside or replacing the deoxidation agent or humidity regulator, thereby the bag becomes smaller and smaller by cutting, and the effective internal volume is reached in a short period of time, making it unusable, etc.SOLUTION: In a storage bag according to the invention, the storage bag has two openings of the same size for taking in and out of historical materials, the hermetically sealing is carried out with a heat seal, and the deoxidation agent and humidity regulator are changed by cutting the bag. The use period of the bag can be prolonged by preferentially cutting one of the two openings or alternately cutting the sealed portions of the two openings. Moreover, the airtightness of the inside of the bag is more stable due to the sealing with the heat seal.SELECTED DRAWING: Figure 1

Description

[Technical field]

[0001] The present invention relates to a sealable storage bag for long-term storage and preservation of various cultural properties (metal, wood, paper, cloth, leather, etc.). [Background technology]

[0002] Conventional airtight storage bags are made by overlapping and closing square sheets to form a bag, sealing both ends and the bottom, and leaving an opening in one place. After placing the materials in the opening, the materials can be stored stably for a long time by sealing them with heat sealing or clips or other fasteners. In this case, by using oxygen absorbers or humidity regulators depending on the materials to be stored, damage from insects, mold, rust, etc. can be prevented, allowing the materials to be stored and preserved in a stable state.

[0003] A conventional airtight storage bag will be explained below with reference to Figure 6. A bag is made by closing both or three sides using a sheet with excellent oxygen barrier properties, and then providing an opening in one place to make an airtight storage bag.

[0004] This is a plan view of the storage material in the storage bag 14, with the opening 15 secured closed and sealed with a clip 16. The clip 16 is used as a fastener for clamping both sides of the sheet to secure it in place. [Prior art documents] [Non-patent literature]

[0005] [Non-Patent Document 1] Mitsubishi Gas Chemical RP System Summary of the Invention [Problem to be solved by the invention]

[0006] Conventional airtight storage bags 14 have only one opening 15, so in order to put the storage material 11 into the airtight bag and seal it, a fixing device according to the size of the opening 15 of the storage bag to be sealed is required, and fixing devices such as a heat sealer or clips 16 are used. In this case, depending on the type of storage material to be put in, it is necessary to put in an oxygen absorber or a humidity control agent 12 or both, and the oxygen absorber and humidity control agent put in the bag must be replaced at least every six months or year. When replacing them, it is necessary to open the sealing and fixing part, and in the case of heat sealing, the fixing part must be cut off. In this case, the bag becomes smaller every time it is replaced, and eventually it becomes necessary to replace it with a new bag. In addition, in the case of clip fixing, the fixing width is large, and it is necessary to put force into the work of fixing with the clip, so it is very time-consuming for beginners and women to get used to it. Furthermore, when the bag is stood upright, the oxygen absorber and humidity control agent put in falls to the bottom of the bag, making it difficult to replace.

[0007] In the case of conventional sealed storage bags, the clip 16 for fixing the bag becomes larger depending on the size of the bag, and the sealing process is laborious for larger bags. Or, if the bag is sealed with heat sealing 3, the heat seal portion is cut, so the bag gradually becomes smaller, and the bag needs to be replaced sooner, which is costly. In order to solve these problems, the present invention aims to reduce costs by providing a structure that provides two openings of the same size for storing stored materials, or a separate small opening for replacing oxygen absorbers and humidity regulators, and a structure that allows the oxygen absorbers and humidity regulators to be replaced more smoothly, thereby making the replacement process more efficient and extending the life of the bags. [Means for solving the problem]

[0008] In order to achieve the above object, the present invention provides a method for minimizing the reduction in size of the storage bag and allowing it to be used for a long period of time even when the heat-sealed portion 3 is cut, by providing two openings 1 and 2 of the same size in the sealed storage bag 1A, or by providing a small replacement opening 5 for replacing the oxygen absorber or humidity regulator in addition to a normal-sized opening 4 for inserting and removing historical materials, as in the storage bag 2B.

[0009] The above-mentioned solution has the following effect. That is, by providing two openings of the same size, openings 1 and 2 can be used alternately when inserting and removing stored materials, for example, opening 1 is used first and opening 2 is used next, or one opening can be used preferentially, making it possible to use the bag for twice the normal period. Furthermore, the sealing work can be performed by heat sealing, which provides a more reliable seal. In addition, in the case of a storage bag that has a replacement opening 5 of a different size in addition to the normal opening, the stored materials are inserted through the large opening 4 and sealed by heat sealing, and the replacement opening 5 for inserting oxygen absorbers and humidity control agents can be fixed with a small clip 6 with a shorter clip length, making the work easier. This makes it possible to make the dimensions of the small clip 6 constant. Furthermore, making it smaller makes the sealing work easier. In addition, a drop prevention stopper 13 is provided inside the bag to prevent oxygen absorbers and humidity control agents from moving to the bottom of the bag and to make the replacement work more efficient. Effect of the Invention

[0010] As mentioned above, by providing two openings of the same size in a storage bag, the loss of material due to cutting the bag can be reduced by half when sealing with heat, by using the two openings alternately or preferentially when inserting and removing stored materials. For example, by making the opening 15 to 20 cm longer than the dimensions of the effective space for storing materials, and cutting the heat-sealed part by 1.5 cm every year, the bag can be used for 20 years, which is twice as long as the usual 10 years when it becomes unusable. In addition, by providing separate openings for inserting and removing materials and for replacing oxygen absorbers and humidity regulators, the storage bag can be used for a long period of time, and in this case, the larger opening is used when inserting and removing stored materials, and the bag is sealed with heat. Periodic checks are performed visually from outside the bag, and periodic replacement of the oxygen absorber and humidity regulator for preserving materials can be done through a small replacement opening, and by providing a stopper to prevent the oxygen absorber and humidity regulator from falling out, replacement time can be shortened and the dimensions of replacement opening 5 for replacing the oxygen absorber and humidity regulator for preserving materials can be reduced. As a result, it is possible to reduce the dimensions of the clip that closes the opening, and the dimensions of the clip can be made the same regardless of the size of the sealed bag, which in turn allows the storage bag to be used for a long period of time and reduces the price of the product.

[0011] Furthermore, since the dimensions of the clip 6 can be reduced, the sealing operations such as attachment and removal using the clip become easier. [Brief description of the drawings]

[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings.

[0014] In the embodiment shown in Fig. 1, two openings of the same size are provided in a storage bag 1A. The two openings 1 and 2 are openings for alternately putting in and taking out stored materials, and have the same width as the storage bag. For example, opening 1 is filled with stored materials 11 and an oxygen absorber or humidity regulator 12 and closed by heat sealing, and opening 2 is also closed by heat sealing. Since the oxygen absorber or humidity regulator 12 for keeping the stored materials in a stable state needs to be replaced at regular intervals, it is inserted and sealed at the same time as the stored materials. When replacing the oxygen absorber or humidity regulator placed inside, openings 1 and 2 are used alternately.

[0015] In the embodiment shown in Fig. 2, the storage bag 2B has two openings. The first opening 4 is for inserting and removing the historical materials, and is the same size as the width of the storage bag. The other opening 5 is for periodically inserting and removing oxygen absorbers and humidity control agents to keep the historical materials stable for a long period of time. The opening 4 for inserting and removing the materials is sealed by heat sealing. However, since the sealed state is to be maintained for a long period of time and there is no need to open it frequently, a clip 16 may be used. Since the opening 5 is only used for the periodic replacement of oxygen absorbers and humidity control agents, the size of the opening can be small, and the dimensions of the clip 6 used can be small, and the opening 5 is sealed with the clip 6.

[0016] 3 shows a structure in which a jig 7 for hanging clothes is provided inside the storage bag to enable airtight storage of clothes hung on a clothes hanger. The jig is rod-shaped and smaller than the width of the storage bag, and problems such as wrinkles will occur if the clothes attached to the sheet of the storage bag with the jig fixing sheet 8 are simply placed inside the bag. Therefore, it is better to place the clothes in the storage bag while still hanging on the clothes hanger, and in this case, the replacement work can be carried out efficiently by using a stopper 13 that prevents the oxygen absorber and humidity conditioner from falling to the bottom of the bag.

[0017] In the embodiment shown in FIG. 4, a drop prevention stopper 13 is attached inside the storage bag to prevent the oxygen absorber and humidity conditioner from dropping to the bottom of the storage bag.

[0018] The structure of the drop prevention stopper is shown in Figure 5. The stopper 13 is made of the same sheet material as the airtight storage bag, has a length approximately equal to the width of the storage bag, and is attached to one or both sides of the storage bag by heat compression bonding one end of the stopper.
