Description

  The present invention relates to a storage case that can store a storage object such as a hanging scroll, an ancient document, a folding screen, a Buddha image, an oil painting, a sculpture, or the like in a good quality state.

Traditionally, museums and museums store objects to be preserved, such as cultural properties, in a storage. In such a storage, the temperature and humidity in the storage are managed.
However, if it is not possible to store cultural assets and other storage objects in such a temperature / humidity-controlled warehouse, store the storage objects such as cultural assets in a storage case such as a paulownia double box. However, the present situation is that the internal humidity change is reduced with respect to the external humidity change.

Further, a humidity control box body (see, for example, Patent Document 1) that stores an object to be preserved for a cultural property such as a hanging shaft while maintaining an airtight state in a box body integrally formed of a material such as metal or synthetic resin. There is a storage case.
Utility Model Registration No. 2530242

However, such a storage case has the following problems.
For example, in the case of a storage case such as a paulownia double box, the inside of the storage case approaches the external humidity due to ventilation with the outside. Therefore, an object to be preserved such as a cultural property inside the preservation case is exposed to an environmental state equivalent to the external humidity, and there is a risk of adversely affecting the object to be preserved such as a cultural property. For example, it is known that the humidity inside the storage case and the inside of the storage case approach approximately the same if the outside humidity continues for an unexpected period such as high humidity or low humidity for several days.

  On the other hand, in the case of a storage case integrally formed of a material such as metal or synthetic resin, the humidity change inside the storage case can be further reduced by maintaining the airtight state and using a humidity control agent. However, expansion and contraction of the air inside the storage case occurs due to external temperature changes. Therefore, the inside of the storage case is repeatedly pressurized and depressurized, and there is a risk of adversely affecting storage objects such as cultural assets housed in the storage case.

  The present invention has been made in view of such a problem, and in the storage case as described above, the humidity inside the storage case against an external humidity change, which is a major factor that deteriorates a storage object such as a cultural property. It is an object of the present invention to be able to alleviate the change and to prevent repeated pressurization / depressurization inside the storage case with respect to an external temperature change.

  Storage case of the present invention made to solve the above-mentioned problems (2: In this section, in order to facilitate understanding of the invention, “the best mode for carrying out the invention” is necessary as necessary. The components described in the column are shown in parentheses, but this description does not mean that the scope of the utility model registration request is limited.) Is a box body (4) having an opening (6); A lid (8) for closing the opening of the box body (4).

Here, the box body (4) is not limited to one opening (6), and may have two or more openings (6).
The box body (4) and the lid (8) of the storage case (2) have non-breathable layers (4c, 8c) that do not have breathability. Moreover, it has air permeability between the box body (4) and the lid body (8) when the opening (6) of the box body (4) of the storage case (2) is closed by the lid body (8). It has a ventilation member (8b), or at least one of the box body (4) and the lid (8) is a non-breathing layer (4c) of the box body (4) and a non-breathing layer of the lid (8) ( 8c), a breathable layer (8b) having breathability is provided.

  As described above, according to the present invention, the box body (4) and the lid body (8) of the storage case (2) are each provided with a non-breathable layer (4c, 8c) that does not have air permeability and the box body (4). It is provided on all or part of the lid (8). For example, in the case of the substantially rectangular parallelepiped storage case (2), the non-breathable layers (4c, 8c) that do not have air permeability may be provided on all of the four side portions, the upper portion, and the bottom portion, and the bottom portion is excluded. The non-breathable layer (4c, 8c) having no breathability may be provided on the four side portions and the upper portion.

  In addition, the degree which can reduce a humidity change becomes large, so that there are many ratios of a non-air-permeable layer. Therefore, for example, in the case of the substantially rectangular parallelepiped storage case (2), as shown in claim 4, the storage case (2c) has a non-breathable layer (4c, 8c) that does not have air permeability in all the portions corresponding to the six surfaces. ) Has a greater degree of mitigation of humidity changes.

  In this way, the greater the degree that the humidity change can be mitigated, the more the humidity of the storage case (2) can be mitigated with respect to the external humidity change, so the preservation objects such as cultural assets stored in the box body (4) The risk of adversely affecting the environment can be avoided.

The storage case (2) configured in this way is suitable for storage of storage objects such as hanging scrolls, ancient documents, folding screens, Buddha statues, oil paintings, sculptures and other cultural assets for which humidity management is desired.
Next, according to the present invention, the storage case (2) includes the box body (4) and the lid (8) in a state where the opening (6) of the box body (4) is closed by the lid (8). In between, it has the ventilation member (8b) which has air permeability. Alternatively, at least one of the box body (4) and the lid (8) is air permeable between the non-breathing layer (4c) of the box body (4) and the non-breathing layer (8c) of the lid (8). The air-permeable layer (8b) having Here, the “air-permeable member (8b) having air permeability” does not include a member provided with an intentional space or a gap, and refers to a member having a micro space inside, for example, wood. The same applies to the “air-permeable layer (8b) having air permeability”.

  Since it has such a structure, the airtight state inside the storage case (2) can be prevented, and the repeated pressurization / depressurization state inside the storage case (2) due to an external temperature change can be prevented. Therefore, it is possible to prevent the storage case (2) from being damaged and the storage case (2) from being damaged due to repeated internal pressure and reduced pressure inside the storage case (2) due to external temperature changes. It is possible to avoid the risk of adversely affecting the storage object such as the cultural property stored in the box body (4) due to the storage case (2) breakage or being exposed to external environmental conditions.

  Here, the storage case (2) due to an external temperature change (2) The process of occurrence of damage to an object to be stored such as a cultural property due to repeated internal pressure and reduced pressure will be described. For example, paints that contain pigments on paper or silk, or paintings drawn with ink, have different shrinkage ratios in the pressurized state and in the decompressed state depending on the type of raw materials and materials. Therefore, internal stress is generated in the painting itself. Then, damage such as cracks occurs in the painting due to internal stress generated in the painting itself. Therefore, the preservation object such as the cultural property may be damaged by the repeated pressurization state / depressurization state inside the storage case (2) due to an external temperature change.

  In addition, when it has the ventilation member (8b) which has air permeability between the box main body (4) and the lid body (8) as described above, it is between the box main body (4) and the lid body (8). It is necessary to incorporate a ventilation member (8b). However, when the air-permeable layer (8b) having air permeability is provided between the non-air-permeable layer (4c) of the box body (4) and the non-air-permeable layer (8c) of the lid (8), Thus, it is possible to save the trouble of incorporating the ventilation member (8b) between the box body (4) and the lid (8).

  Further, in order to further reduce the humidity change inside the storage case (2) against the external humidity change, as shown in claim 2, a predetermined relative humidity is applied to the box body (4) of the storage case (2). One or more humidity control agents (14a, 14b) adjusted to be good. The one or more humidity control agents (14a, 14b) adjusted to a predetermined relative humidity act to keep the humidity inside the storage case at the adjusted predetermined relative humidity. In the case of the storage case (2) that cannot be kept completely airtight, the humidity inside the storage case (2) is external even if it is adjusted to maintain a predetermined relative humidity in the initial state. Since the humidity changes with the time of use due to the change in humidity, it is necessary to replace the humidity control agents (14a, 14b).

  Here, the humidity inside the storage case (2) can be confirmed by putting a hygrometer or an indicator card displaying the humidity in the storage case (2). When the humidity in the storage case (2) deviates from the initially set humidity, it can be used repeatedly as long as the humidity control agent (14a, 14b) is replaced.

  Although it has been described that one or more humidity control agents (14a, 14b) adjusted to a predetermined relative humidity may be stored in the box body (4) of the storage case (2), the humidity control agents (14a, 14b) ) Is stored separately from objects to be stored such as cultural assets, for example, as shown in claim 3, it has a contact prevention member (16, 18) having air permeability (16a-16e, 18a-18e). Is preferred. In this case, the “contact prevention member (16, 18) having air permeability (16a to 16e, 18a to 18e)” is different from the above-described “air ventilation member (4a, 4b, 8b)”. A member with a positive ventilation structure. That is, the “contact prevention member (16, 18) having air permeability (16a to 16e, 18a to 18e)” includes a member provided with an intentional space or a gap, for example, one or more ventilation holes or a mesh shape. This means a member that can store a storage object such as a cultural property and a humidity control agent (14a, 14b) separately. Storage objects such as cultural properties stored in the storage case (2) are conditioned by the humidity control agent (14a, 14b), and the humidity control agent (14a, 14b) is applied by the contact prevention member (16, 18). Store separately.

  In the storage case (2) described above, the following points are important in order to enhance the effect of reducing the humidity change inside the storage case (2) with respect to the external humidity change. That is, the ventilation between the outside and the inside of the storage case (2) is limited to the ventilation member (8b) having the space between the box body (4) and the lid (8). Further, the ventilation layer (8b) has ventilation between the outside and the storage case (2) between the non-venting layer (4c) of the box body (4) and the non-venting layer (8c) of the lid (8). It is limited.

  Therefore, as shown in claim 5, the storage case (2) has pressure contact means (20a, 20b) for pressing the lid (8) against the peripheral edge (6a) of the opening (6) of the box body (4). It is preferable to have. That is, a space and a gap are generated between the box body (4) and the lid body (8) by pressing the lid body (8) against the peripheral edge (6a) of the opening (6) of the box body (4). Can be prevented. Therefore, the effect of relieving the humidity change inside the storage case (2) against the external humidity change can be enhanced.

  Various materials for forming the non-ventilated layers (4c, 8c) respectively provided in the box body (4) and the lid (8) of the storage case (2) can be considered. For example, as shown in claim 6 In addition, it is preferable to form the non-breathing layer (4c, 8c) with the metal (4c, 8c). This is because the metals (4c, 8c) do not have air permeability and are easy to process.

  Various types of metal (4c, 8c) are conceivable. For example, as shown in claim 7, an aluminum plate (4c, 8c) or an aluminum foil (4c, 8c) is more preferable.

  As can be understood from this description, the metal (4c, 8c) is not required to have high rigidity, and may be an aluminum foil (4c, 8c) or a thin aluminum plate (4c, 8c). In short, it is only necessary to form non-breathable layers (4c, 8c) that do not have breathability.

  Further, as shown in claim 8, the non-breathable layer (4c, 8c) may be formed of a synthetic resin (4c, 8c). The synthetic resins (4c, 8c) do not have air permeability, are excellent in corrosiveness and lightness, and can cope with mass production.

  Embodiments to which the present invention is applied will be described below with reference to the drawings. Needless to say, the embodiments of the present invention are not limited to the following examples, and can take various forms as long as they belong to the technical scope of the present invention.

[Description of configuration]
FIG. 1A is a perspective view showing a box body and a lid body in which a humidity control agent and a partition plate are stored in a storage case of the present embodiment, and FIG. It is a perspective view which shows the whole with which it mounted | worn, (c) is sectional drawing in the AA of (b).

As shown in FIG. 1A, the storage case 2 includes a box body 4, two humidity conditioners 14 a and 14 b, two partition plates 16 and 18, and a lid 8.
The box body 4 is a substantially rectangular parallelepiped and has four side portions 401 to 404, a bottom portion 405, and an opening 6. The four side portions 401 to 404 are formed of two short side portions 401 and 402 and two long side portions 403 and 404.

The four side portions 401 to 404 and the bottom portion 405 of the box body 4 are formed of a plate material in which an aluminum foil 4c is sandwiched between paulownia materials 4a and 4b. Here, the paulownia materials 4a and 4b correspond to a breathable member having air permeability or a breathable layer having air permeability, and the aluminum foil 4c corresponds to a non-breathable layer having no breathability. The size is set so as to cover the outer sides of the four side portions 401 to 404 of the box body 4 with the same configuration. That is, the lid 8 is a substantially rectangular parallelepiped and has four side portions 801 to 804, an upper portion 805, and an opening 806. The four side portions 801 to 804 are formed of two short side portions 801 and 802 and two long side portions 803 and 804.

  The four side portions 801 to 804 and the upper portion 805 of the lid body 8 are formed of a plate material in which an aluminum foil 8c is sandwiched between paulownia materials 8a and 8b. Here, the paulownia materials 8a and 8b correspond to a breathable member or a breathable layer having breathability, and the aluminum foil 8c corresponds to a non-breathable layer having no breathability.

  As described above, the lid body 8 is set to have a size that covers the four side portions 401 to 404 of the box body 4, but the outer surface of the box body 4 and the inside of the lid body 8 in the covered state. It is better that the gap with the peripheral surface is set small. The distance from the inner surface of the upper portion 805 of the lid body 8 to the tips of the four side portions 801 to 804 perpendicular to the inner surface of the upper portion 805 is four from the outer surface of the bottom portion 405 of the box body 4 to the outer surface of the bottom portion 405. The distance is set to be slightly shorter than the distance to the tips of the side portions 401 to 404.

  Since the lid 8 and the box body 4 are configured as described above, when the opening 6 of the box body 4 is closed with the lid 8, the outside of the storage case 2 is stored as shown in FIG. Ventilation with the inside of the case 2 is performed only through the inside of the paulownia material 8b.

  Further, the box body 4 houses two partition plates 16 and 18. The partition plates 16 and 18 are formed of a rectangular paulownia material. The outer shape of the partition plates 16 and 18 is set so as to be accommodated in the box body 4 approximately equal to the cross-sectional shape of the inner side of the box body 4 parallel to the two short side portions 401 and 402 of the box body 4. Yes. Moreover, the partition plate 16 has ventilation holes 16a to 16e in the plate thickness direction, and the partition plate 18 has ventilation holes 18a to 18e in the plate thickness direction.

  And the hole diameter of the ventilation holes 16a-16e of the partition plate 16 is set to the magnitude | size which the ventilation | gas_flowing with the preservation | save objects, such as a cultural property accommodated in the box main body 4, and the humidity control agent 14a exceeds predetermined ventilation volume. The And the plate | board thickness of the partition plate 16 is set to the thickness which has the rigidity which can store separately the humidity control agent 14a accommodated in the box main body 4, and preservation | save objects, such as a culture material. The vent holes 18a to 18e and the plate thickness of the partition plate 18 are set similarly. In addition, the partition plate 16 is set at a position that is parallel to the inner surface of the short side portion 401 of the box body 4 and separated by a distance that can store the humidity control agent 14a. The partition plate 16 is fixed to the box body 4. The partition plate 18 is set at a position separated from the inner surface of the short side portion 402 of the box body 4 by a distance that can accommodate the humidity control agent 14b. The partition plate 18 is fixed to the box body 4. Here, the partition plates 16 and 18 correspond to contact preventing members capable of preventing contact between the humidity control agents 14a and 14b and the storage object stored in the box body.

  In addition, although the partition plates 16 and 18 were being fixed to the box main body 4 in the above, it is not restricted to this. For example, the external dimensions of the partition plates 16 and 18 are such that the long side portion 403 and the long side portion 404 are longer than the cross-sectional shape that cuts the inside of the box body 4 parallel to the two short side portions 401 and 402 of the box body 4. It is good also as a structure which provides a groove | channel in the two long side parts 403 and 404 of the box main body 4, and makes it fit a little in a direction so that the size of the partition plates 16 and 18 may be fitted.

  The size of the box body 4 is divided into the size of the storage object such as the cultural property stored in the box body 4 and the size and partitioning of the humidity control agents 14a and 14b suitable for conditioning the storage object such as the cultural property. It is set in consideration of the size of the plates 16 and 18. Note that the appropriate size for conditioning the preservation object such as the cultural property is related to the weight of the humidity control agents 14a and 14b, but the appropriate amount for conditioning the preservation object such as the cultural property. The weights of the wetting agents 14a and 14b will be described later in [Explanation of Experimental Results].

  Therefore, a storage object such as a cultural property (not shown) stored between the partition plate 16 and the partition plate 18 is conditioned by the humidity control agent 14a through the vent holes 16a to 16e of the partition plate 16, and The humidity is adjusted by the humidity control agent 14b through the vent holes 18a to 18e. Here, two sets of the partition plates 16 and 18 and the humidity control agents 14a and 14b are housed, but either one set may be used. In addition, a plurality of partition plates may be provided to alternately store a humidity control agent and a storage object such as a cultural property. When a plurality of partition plates are provided, the humidity control agents 14a and 14b are respectively stored between the inner surfaces of the two short side portions 401 and 402 of the box body 4 and the partition plates 16 and 18, respectively. preferable. Further, the storage objects such as cultural properties and the humidity control agents 14a and 14b can be stored separately by the partition plates 16 and 18.

  Here, the humidity control agents 14a and 14b are, for example, balls of which 95% of the components are silicon dioxide, and are stored in a predetermined amount in a bag having air permeability. Specifically, it is marketed as Artsorb (trade name of Fuji Silysia Chemical Co., Ltd.).

And as shown in FIG.1 (b), after closing the opening part 6 of the box main body 4 with the cover body 8, two ring-shaped elastic belts 20a and 20b are attached. Here, as described above, the distance from the inner surface of the upper portion 805 of the lid 8 to the tips of the four side portions 801 to 804 perpendicular to the inner surface of the upper portion 805 is the outer surface of the bottom portion 405 of the box body 4. Since the distance is set to be shorter than the distance to the tips of the four side portions 401 to 404, the lid body 8 can be pressed against the peripheral edge 6 a of the opening 6 of the box body 4. That is, it is possible to prevent a space or a gap from being generated between the box body 4 and the lid body 8. Here, the two elastic belts 20a and 20b correspond to pressure contact means for pressing the lid 8 against the opening 6 of the box body 4. Therefore, the ventilation between the outside of the storage case 2 and the inside of the storage case 2 described above is paulownia. Only through the inside of the material 8b, it is possible to enhance the effect of reducing the humidity change inside the storage case 2 with respect to the outside humidity change.

[Description of usage]
Next, how to use the storage case 2 will be described.
First, the humidity control agents 14a and 14b are accommodated between the inner surfaces of the two short side portions 401 and 402 of the box body 4 and the partition plates 16 and 18, respectively.

  Then, a storage object (not shown) such as a cultural property is stored between the two partition plates 16 and 18. During storage, a storage object such as a cultural property can be stored in a stable state by a support member or a buffer member (not shown). This is effective for preventing a storage object such as a cultural property from being rolled or toppled and damaged in the box body 4 such as when the storage case 2 is carried or transported.

  After storing an object to be preserved such as a cultural asset, a lid 8 is placed so as to close the opening 6 of the box body 4. Then, two elastic belts 20 a and 20 b for pressing the peripheral edge 6 a of the opening 6 of the box body 4 inside the lid body 8 are attached. That is, it is possible to prevent a space or a gap from being generated between the peripheral edge 6 a of the opening 6 of the box body 4 and the inside of the lid 8 by pressing the cover 8 against the peripheral edge 6 a of the opening 6 of the box body 4.

  Here, the humidity inside the storage case 2 can be confirmed by putting a hygrometer or an indicator card displaying the humidity inside the storage case 2. If the humidity inside the storage case 2 deviates from the initially set humidity, the elastic belts 20a and 20b are removed and the lid 8 is pulled away from the box body 4 in the reverse procedure to the above procedure. The humidity control agents 14a and 14b accommodated in the storage case 2 can be exchanged. And since it can be used repeatedly many times, preservation objects, such as a cultural property, can be preserve | saved for a long time with a good quality state.

[Explanation of experimental results]
Next, the humidity control effect of the storage case 2 will be described based on the experimental results shown in FIG.
FIG. 2 (a) shows the humidity with respect to the number of days elapsed when 40g and 60g of the humidity control agents 14a and 14b adjusted to a relative humidity of 60% RH are stored in the storage case 2 of the present embodiment and when only the paulownia box is used. It is a figure which shows a change, (b) is the case where 100g, 160g of the humidity control agents 14a and 14b adjusted to the relative humidity 60% RH are stored in the storage case 2 of the present embodiment, and the case where only the paulownia box is used It is a figure which shows the humidity change with respect to the elapsed days.

  As shown in FIG. 2A, when the relative humidity of the outside air is 80RH%, in the case of only the paulownia box, the relative humidity inside the paulownia box is almost equal to the relative humidity 80% RH of the outside air after several days. However, when 40g and 60g of the humidity adjusting agents 14a and 14b adjusted to 60% RH are stored in the storage case 2, the relative humidity inside the storage case 2 is about 74% relative humidity after 30 days. The relative humidity does not reach 80% RH. In FIG. 2A, “humidity adjusting agent 40 g” is the total weight of the humidity adjusting agent 14 a and the humidity adjusting agent 14 b. The same applies to “humidity control agent 60 g”.

  Further, as shown in FIG. 2 (a), when the relative humidity of the outside air is 40RH%, when only the paulownia box is used, the relative humidity inside the paulownia box becomes almost equal to the relative humidity 40% RH of the outside air when 10 days or more have passed. ing. However, when 40g and 60g of the humidity adjusting agents 14a and 14b adjusted to 60% RH are stored in the storage case 2, the relative humidity inside the storage case 2 is about 46% relative humidity after 30 days. The relative humidity does not reach 40% RH.

  Further, FIG. 2B shows the humidity control effect when the weights of the humidity control agents 14a and 14b accommodated in the storage case 2 are increased as compared with FIG. As shown in FIG. 2B, when the relative humidity of the outside air is 80RH%, in the case of only the paulownia box, the relative humidity inside the paulownia box is almost equal to the relative humidity 80% RH of the outside air when several days have passed. However, when 100g and 160g of the humidity adjusting agents 14a and 14b adjusted to 60% RH are stored in the storage case 2, the relative humidity inside the storage case 2 is about 71% relative humidity after 30 days. The relative humidity does not reach 80% RH. In FIG. 3B, “humidity control agent 100 g” is the total weight of the humidity control agent 14a and the humidity control agent 14b. The same applies to “humidity control agent 160 g”.

  Further, as shown in FIG. 2 (b), when the relative humidity of the outside air is 30 RH%, the relative humidity inside the paulownia box becomes almost equal to the relative humidity of the outside air 30% RH when only the paulownia box is passed 10 days ago. ing. However, when 100 g of the humidity adjusting agents 14a and 14b adjusted to a relative humidity of 60% RH is stored in the storage case 2, the relative humidity inside the storage case 2 is about 41% relative humidity after 30 days. It indicates that the humidity has not reached 30% RH. Further, when 160 g of the humidity adjusting agents 14a and 14b adjusted to a relative humidity of 60% RH is stored in the storage case 2, the relative humidity inside the storage case 2 is about 44% relative humidity after 30 days. It indicates that the humidity has not reached 30% RH.

  This experimental result shows that the humidity control effect increases as the weight of the humidity control agents 14a, 14b stored in the storage case 2 increases, and the humidity control effect varies depending on the weight of the humidity control agents 14a, 14b. .

  That is, an appropriate weight of the humidity control agents 14a and 14b may be set in accordance with the size and weight of an object to be stored such as a cultural property stored in the storage case 2 and the replacement period of the humidity control agents 14a and 14b.

[Description of effects]
(1) In the case of a conventional storage case such as a paulownia double box, the inside of the storage case approaches the external humidity due to ventilation with the outside, and is integrally formed of a material such as metal or synthetic resin. In the case of the storage case, the expansion and contraction of the air inside the storage case occurs due to an external temperature change, and there is a risk of adversely affecting the storage object such as a cultural property housed in the storage case.

  In contrast, when the storage case 2 closes the opening 6 of the box body 4 with the lid 8, the aluminum foil 4c that does not have air permeability and the ventilation that the lid 8 has. It becomes the structure which has the paulownia material 8b which has air permeability between the aluminum foil 8c which does not have property, and ventilation | gas_flowing with the inside of the storage case 2 and the inside of the storage case 2 is performed only through the inside of the paulownia material 8b. Therefore, it is possible to mitigate the humidity change inside the storage case 2 against external humidity changes, which is a major factor that degrades the storage object such as cultural assets, and to apply the internal temperature inside the storage case 2 against external temperature changes. Repetition of the pressure state and the decompression state can be prevented.

  (2) Moreover, the partition plate 16 which has the vent holes 16a-16e and the partition plate 18 which has the vent holes 18a-18e are provided in the inner surface side of the two short side parts 401 and 402 of the box main body 2, This partition plate The humidity control agent 14 a is accommodated between the short side part 401 of the box body 4 and the humidity control agent 14 b is accommodated between the partition plate 18 and the short side part 402 of the box body 4. Therefore, the humidity change inside the storage case 2 can be further mitigated with respect to the external humidity change, and the humidity can be maintained at the adjusted relative humidity. Can be stored for a long time with good quality.

  (3) Since the peripheral edge 6a of the opening 6 of the box body 4 can be press-contacted by the lid body 8 by the elastic belts 20a and 20b, it is possible to prevent a space or a gap from being generated between the box body 4 and the lid body 8. it can.
