Description

  The present invention relates to a shape-retaining material for bags that fills bags (including items called bags, the same applies hereinafter) to maintain the shape of the bags.

  A variety of fillers are used for the shape-retaining material filled in the bag, from rounded newspapers to urethane, but most of them are treated as non-sale products that use waste materials, and the substantial composition required to perform better functions. Tends to be relatively neglected. Occasionally, a deodorizing pack (for example, refer to the following patent document) in which a bag such as a nonwoven fabric is filled with a porous material is used for the purpose of extinguishing internal odors or preventing mold from being generated due to moisture. It is also routinely placed with the shape.

  However, as described above, when the waste-use filler and deodorant pack are used in combination, the insertion position of the deodorant pack, etc., or the displacement caused by vibration during transportation, etc., or via the filler For example, it is difficult to transport the bag as a leather product in a harsh environment and store it properly over a long period of time.

  The present invention has been made in view of the above circumstances, and has a simple structure and can effectively retain and store a high-quality bag according to its material, size, or shape. The purpose is to provide a shape-retaining material.

  In order to solve the above-mentioned problems, the shape-retaining material for bag according to the present invention comprises a cushioning material made of sponge, urethane, moisture-absorbing sheet (newspaper), etc. A shape-retaining material that movably accommodates one or a plurality of inclusion bodies that are wrapped with a breathable sheet, wherein the outer packaging body is breathable, and the humidity control material is one type or two or more types It is characterized by comprising a porous material, a hygroscopic material, or a hygroscopic sheet. Examples of the porous material include particles or powders of charcoal, bamboo charcoal, activated carbon, or zeolite, examples of the moisture absorbing material include silica gel, and examples of the moisture absorbing sheet include newspaper. The buffer material may be made of a moisture absorbent sheet having humidity control properties.

  An anchor band may be extended from two or more side surfaces of the breathable sheet of the inclusion body. The anchor band can be appropriately adjusted in width and length in accordance with the amount of the extending downward direction and the material and size of the cushioning material.

  In the present invention, by filling a cushion made of a breathable sheet with a cushioning material, it is possible to prevent both the shape retention of the shaped article and the elasticity and breathability of the shape retaining material as a whole. In addition, since the inner body is surrounded by the cushioning material so as to be freely movable, the position of the inner body within the outer body can be freely set.

  Moreover, when the position of the inclusion body is set as described above, the anchor band is sandwiched between the cushioning materials by the configuration in which the anchor band is extended on the side surfaces of the breathable sheet of the inclusion body in two or more directions. Even when the shape retaining material is filled into the cage through a narrow frontage, or transported under harsh conditions, or when it is handled violently during distribution, It is possible to maintain an appropriate position where the humidity control function and the deodorizing function can be satisfactorily performed inside the bag.

  Furthermore, a humidity control material comprising a granular material or powder of a porous material such as charcoal, bamboo charcoal, activated carbon or zeolite, a hygroscopic material such as silica gel, or a hygroscopic sheet such as newspaper, has a moisture absorbing effect and a deodorizing effect. Of course, depending on the selection and preparation of the material, it is not just a hygroscopic effect, but it has a relatively hygroscopic effect in a high-humidity environment and a relatively humidifying effect in a dry environment. On the other hand, a proper dry state avoiding overdrying can be maintained. In addition, depending on the material of the bag (product made only of leather, combined product of leather and resin sheet, or resin sheet product, etc.), the volume balance between the inner package and the outer package that perform the function of the moisture absorption pack By adjusting the arrangement, it contributes to the suppression of deterioration of the shaped article with higher practicality according to the material.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a shape retaining material for a bag according to the present invention will be described below based on the drawings.
In the shape retaining material for bag according to the present invention, a cushioning material 1 is wrapped in a breathable sheet 2 and a moisture conditioning material 4 made of porous material (charcoal) particles is wrapped in a breathable sheet 5. One or a plurality of inclusion bodies 6 are accommodated so as to be freely movable (see FIG. 1).

  The breathable sheets 2 and 5 that are the foreskin of the outer package 3 and the inner package 6 are designed in consideration of design, texture, strength, lifetime, etc. from nonwoven fabric to silk, provided that breathability is ensured. It is possible to select a wide range of materials. The breathable sheets 2 and 5 are formed by bending or the like according to the shape of the article 8 to be held, and the edges are closed by welding, bonding or sewing as appropriate, thereby forming a package. The basic shape of the outer envelope 3 or the inner envelope 6 is formed by filling the humidity adjusting material 4 made of the material 1 or the porous material and closing the filling port as described above.

  In the example shown in FIGS. 1 to 4, a sponge piece is used as the buffer material 1. The size of the cushioning material 1 is appropriately selected as an average size: a piece of about 1 cm to 4 cm or a lump of a desired size according to the volume of the shaped article. In addition, as the particle size of the porous material, a powder or granule of about 1 μm to several tens of mm, or a lump formed by rolling up a moisture absorbent sheet is appropriately selected according to the volume or shape of the article 8 to be held. It will be.

  Even in the inner package 6 accommodated in the outer package 3, the size, quantity, and arrangement are appropriately selected according to the shape of the container of the article 8 to be held. The position of the inner package 6 can be freely moved inside the outer package 3, but it is possible to maintain a position that is not less than adjusted by the resistance due to the presence of the cushioning material 1 (FIG. 2).

  Furthermore, as a measure for stabilizing the arrangement, the connecting member 9 such as a hook-and-loop fastener is fixed to the side face of the outer envelope 3 or the inner envelope 6 and the units of the shape-retaining material 0 that are in contact with each other, or the unit When a plurality of inclusion bodies 6 are accommodated in the body (see FIG. 3), a structure is employed in which these inclusion bodies (not shown; similar to the configuration of the outer packaging body 3 shown in FIG. 3) can be connected to each other. May be.

  Alternatively, the anchor bands 7 and 7 are extended from the side surfaces of the air-permeable sheet 5 of the inclusion body 6 in two or more directions, and the position adjusted by the interference of the cushioning material 1 with respect to the anchor band 7 is maintained. You can also. The anchor band 7 can be appropriately adjusted in width and length according to the quantity in the extending direction and the material and size of the cushioning material 1.

Although various modes can be considered for the humidity control material 4, charcoal (porous material) and newspaper (humidity absorbing sheet) were extracted from them, and a sponge was further added to observe each humidity control effect.
Observation is carried out by putting the shape-retaining material using them as the humidity control material 4 into a 12-liter sealed plastic container (see FIG. 6) and taking the poly container into and out of the thermostatic chamber (see FIG. 7). The temperature inside these plastic containers was changed to create a change in relative humidity within the plastic container, and the humidity change over time was measured.

  In the graph of FIG. 4, the overlapping lines located at the bottom indicate the temperature change made using the thermostat, and the four lines positioned at the top are in order from the top, Humidity change in plastic container without shape-retaining material, humidity change in plastic container with shape-retaining material using sponge as humidity-conditioning material 4, shape-retaining material using newspaper as humidity-conditioning material 4 The change in humidity in the plastic container and the change in humidity in the plastic container in which a shape-retaining material using charcoal as the humidity-controlling material 4 is placed are described in order.

  According to FIG. 4, the humidity control effect is observed in newspaper and charcoal. That is, compared with sponge, the relative humidity has increased since 15:00 when it was taken out of the thermostatic bath. However, both the newspaper and charcoal once showed the maximum humidity, and then the stable humidity (newspaper: about 68). %, Charcoal: about 45% RH). According to the results obtained by the observation, newspapers are conditioned at a relatively high humidity (about 65% RH to about 85% RH), and charcoal is relatively low humidity (about 40% RH to about 55% RH). Humidity is controlled at. On the other hand, the sample using the sponge does not show a tendency to decrease after the humidity once shows the maximum value. This is understood to mean that the moisturizing power is high.

FIG. 5 is a graph in which changes in relative humidity created by the same method as in FIG. 4 are repeated at regular intervals (4 hours).
In the graph, the overlapping lines positioned at the bottom indicate the temperature change in the plastic container made using the thermostatic bath, and the three lines positioned at the top indicate the topmost In order, the humidity change in the plastic container without the shape-retaining material, the humidity change in the poly-container with the shape-retaining material using the sponge as the humidity control material 4, and the charcoal as the humidity control material 4 The humidity change in the plastic container containing the profile is described in order.

According to the graph, the moisture conditioning effect of charcoal is noticeable.
From these observation results, the selection and mixing of the material to be used as the humidity control material 4 (for example, the humidity control material formed by mixing the charcoal particles and the newspaper pieces), or the humidity control material 4 and the humidity control property are determined. It is recognized that an appropriate humidity control effect for a desired material can be achieved by combining it with a cushioning material (newspaper, etc.) 1 possessed, and this effect is understood to have a high follow-up property even in a sudden change in relative humidity. Is done.
