Description

  The present invention relates to a storage container that stores a stored object at a constant temperature using a heat storage agent, and particularly relates to a storage container that stores a stored object at a constant temperature using a plurality of heat storage agents.

  2. Description of the Related Art Conventionally, a stored object such as food is kept cold using a heat storage agent. As the heat storage agent generally used, one having a melting point of less than 0 ° C. is used. For example, after being cooled at a low temperature of about −25 ° C. in a freezer, the heat storage agent is taken out from the freezer and used. In addition, when the heat storage agent is frozen, it is generally frozen in an environment that is 10 ° C. or more lower than the freezing point. Therefore, even a heat storage agent having a melting point near 0 ° C. is frozen in an environment of −25 ° C. There is often. Therefore, if the heat storage agent is used in a state where it is taken out from the freezer, the article to be stored is cooled to 0 ° C. or lower.

  Among the objects to be kept cold using the heat storage agent, the storage environment is preferably about 2 to 8 ° C., such as a specimen, and it is not preferable to keep it cool at 0 ° C. or less. There are also things. Therefore, when keeping such objects to be stored, after leaving the heat storage agent from the freezer, use it after leaving it at room temperature or in a refrigerator for about 30 minutes to 3 hours to raise the temperature of the heat storage agent to the melting point. To be done. However, taking out the heat storage agent from the freezer and leaving it for a certain period of time is not efficient and cannot be used immediately when desired.

  Here, it is considered that the storage object is not cooled too much by using two heat storage agents. In such a case, the two heat storage agents are arranged so as to overlap each other, and the heat storage agent that is not the storage object side is solidified, and the heat storage agent on the storage object side is not solidified, The stored item is indirectly cooled by the heat storage agent solidified through the heat storage agent that has not solidified. Thereby, the temperature of the article to be stored does not become lower than the freezing point of the heat storage agent that has not solidified, and the article to be stored can be prevented from being cooled too much.

  In addition, it is possible to keep the storage object at a desired temperature by using the above-described heat storage agent in the freezing region. In this case, the two heat storage agents are arranged so as to overlap each other, and the storage object side heat storage is performed. By keeping the agent in a solidified state, the article to be stored can be kept at a desired temperature.

  Thus, for example, Patent Document 1 discloses a constant temperature storage tool for storing the storage object at a constant temperature by superimposing two heat storage agents. This constant-temperature storage tool is configured to be attachable to the inner wall surface of a storage container in which an object to be stored is stored, and has two layers of pockets that can store a heat storage agent. As described above, the heat storage agent stored in each of the double pockets is in a state in which one of the storage object side and the non-storage object side is solidified and the other is solidified. By setting it as the state which does not exist, a to-be-stored object can be stored at desired temperature.

Design Registration No. 1433322

  However, in the constant temperature storage device as described above, the solidified heat storage agent is stored in one of the two layers of pockets, and the non-solidified heat storage agent is stored in the other, so that they may be mistaken. If this happens, the stored object cannot be stored at a desired temperature. In addition, when attaching to the inner wall surface of the storage container, there is a risk that the orientation of the attachment will be wrong, in that case, even if there is no mistake in putting the solidified heat storage agent and the non-solidified heat storage agent as described above In addition, the arrangement of the solidified heat storage agent and the non-solidified heat storage agent is opposite to the desired one, and the stored object cannot be stored at a desired temperature in the same manner as described above.

  Therefore, the applicant of the present invention is a constant temperature storage tool attached to the inner wall surface of a storage container in which an object to be stored is stored, and includes a first storage unit in which the first heat storage agent is stored so that it cannot be taken out, and a constant temperature. A second storage unit that is adjacent to the inner wall surface side of the first storage unit when the storage tool is attached to the storage container and stores the second heat storage agent in a removable manner; The constant temperature storage tool which equipped the attachment part for attaching a constant temperature storage tool to a storage container on the outer surface on the opposite side to the 1st accommodating part of a part was devised.

  In this constant temperature storage tool, the first storage portion of the second storage portion is opposite to the first storage portion of the first storage portion and the second storage portion for storing the heat storage agent for storing the storage object at a constant temperature. Since it is attached to the storage container by the attachment portion provided on the outer surface on the side, it is possible to avoid mistaken attachment direction with respect to the storage container. In addition, since the first storage unit stores the first heat storage agent so that the first heat storage agent cannot be taken out, the second storage unit only stores the second heat storage agent in use, and the object to be stored can be stored in a desired manner. In order to store at a temperature, when one of the first heat storage agent and the second heat storage agent is not solidified and the other is solidified, the heat storage agent is solidified with the non-solidified heat storage agent. It is possible to avoid mistakenly putting the heat storage agent in the first storage unit and the second storage unit. Further, as described above, since the heat storage agent is attached to the storage container in the correct direction and the heat storage agent is not mistakenly inserted into the first storage unit and the second storage unit, the positions of the two heat storage agents with respect to the storage object It can be avoided that the relationship becomes wrong.

  By the way, the constant temperature storage tool as described above may be attached to the ceiling surface of the storage container. In particular, when the object to be stored is cooled by the heat storage agent, since the cold air is generally directed from the upper part to the lower part, it is preferable to attach a constant temperature storage tool to the ceiling surface of the storage container. In that case, it is necessary to make the structure of the said attachment part into the structure which a constant temperature storage tool does not fall easily from a ceiling. For example, if the constant temperature storage tool is attached to the ceiling surface of the storage container in a non-detachable manner by sewing or the like, the constant temperature storage tool can be reliably prevented from falling off the ceiling. In addition, when attaching a constant temperature storage tool to the inner wall surface other than the ceiling surface of the storage container, if the constant temperature storage tool is attached to the inner wall surface of the storage container so as not to be detachable by sewing or the like, When a strong vibration is applied to the storage container, it is possible to reliably prevent the constant temperature storage tool from falling off the inner wall surface of the storage container.

  As described above, installing the constant temperature storage device on the inner wall surface of the storage container in a non-detachable manner is one effective means for reliably preventing the constant temperature storage device from falling off the inner wall surface of the storage container. is there.

  Here, when the above-mentioned constant temperature storage device is installed on the inner wall surface of the storage container so as not to be detachable, the second heat storage agent is solidified as a second state in order to avoid the object to be stored being cooled too much. If it is stored in the storage section, the first heat storage agent that has not solidified is interposed between the solidified second heat storage agent and the storage object, thereby preventing the storage object from being cooled too much. However, in the case where the object to be stored is kept at a desired temperature in the freezing area, the first heat storage agent cannot be taken out from the first storage portion, so that the first heat storage agent is solidified. In addition, even when the second heat storage agent is solidified, in the state where the second heat storage agent is stored in the second storage portion, the second heat storage agent is stored between the second heat storage agent and the storage object. The first heat storage agent that is not solidified intervenes to keep the storage object at a desired temperature. It disappears come.

  Moreover, when it is set as the structure which attaches a fastener etc. to the 1st accommodating part and can take out the 1st thermal storage agent from the 1st accommodating part, take out the 1st thermal storage agent from the 1st accommodating part. A solidified state can be obtained. However, as described above, when the stored item is not cooled too much, the first heat storage agent is not solidified, while the stored item is maintained at a desired temperature in the freezing region. Since it is necessary to store the heat storage agent in the first storage unit in a solidified state, the operation of taking out and storing the first heat storage agent from the first storage unit when used in two different environments. It becomes indispensable and the work becomes complicated, and accordingly, there is a possibility that an error in inserting the heat storage agent in a storage unit different from the storage unit in which the heat storage agent is stored may occur.

  Therefore, the applicant of the present invention, in the configuration in which the storage object is stored at a constant temperature using the solidified heat storage agent and the non-solidified heat storage agent as described above, the positional relationship between the two heat storage agents relative to the storage object is incorrect. While avoiding becoming a thing, the earnestly researched about the storage container which can avoid reliably the member which accommodates a thermal storage agent falling off from the inner wall face of a storage container.

  The present invention uses these two heat storage agents by using a solidified heat storage agent and a non-solidified heat storage agent while reliably avoiding a member storing the heat storage agent from falling off the inner wall surface of the storage container. It is an object of the present invention to provide a storage container that can be stored at a constant temperature without causing the positional relationship of the agent to the storage object to be incorrect.

In order to achieve the above object, the present invention provides:
A storage container in which a heat storage agent storage unit for storing the heat storage agent is installed,
The heat storage agent storage section is
It is installed in a non-removable manner on any inner wall surface of the storage container,
A first storage unit capable of storing the solidified heat storage agent in a removable manner;
A second storage part in which a heat storage agent that has not solidified is stored in an unremovable manner ;
A third storage portion that can store the solidified heat storage agent so as to be removable is arranged in this order from the inner wall surface side.

  In the present invention configured as described above, the heat storage agent is stored because the heat storage agent storage portion in which the heat storage agent is stored is detachably installed on any inner wall surface of the storage container. It is reliably avoided that the heat storage agent storage part falls off from the inner wall surface of the storage container. In addition, the heat storage agent storage part can take out the solidified heat storage agent so that it can be taken out, the second storage part in which the heat storage agent that has not solidified is stored, and the solidified heat storage agent can be taken out Since the third storage part that can be stored in the storage container is arranged in this order from the inner wall surface side to which the storage container is attached, the second storage part can be avoided in order to avoid the object to be stored being cooled too much. In a state where the heat storage agent stored in the container is not solidified, by storing the solidified heat storage agent in the first storage unit, the heat storage agent that has not solidified is stored between the solidified heat storage agent and the storage object. Intervening, thereby avoiding the object to be stored too cold. In addition, when keeping the article to be stored at a desired temperature in the refrigerated region, the solidified heat storage agent is stored in the third storage unit, so that the solidified heat storage agent and the object to be stored are solidified. There is no heat storage agent present, so that the article to be stored can be kept at a desired temperature in the freezing zone.

  In addition, if the inner wall surface to which the heat storage agent storage portion is attached is the ceiling surface of the storage container, the above-described effect due to the heat storage agent storage portion being installed in the storage container in a non-detachable manner is great.

  In addition, if the surface of the third storage portion opposite to the second storage portion is formed of a breathable sheet, the heat storage agent stored in the second storage portion or the third storage portion. In order to avoid the cool air and heat from being transferred to the storage object and its surroundings, and to prevent the storage object from being cooled too much, 3 storage part becomes difficult to be bulky.

  According to the present invention, since the heat storage agent storage portion in which the heat storage agent is stored is detachably installed on any inner wall surface of the storage container, the member storing the heat storage agent is the inner wall surface of the storage container. It is possible to reliably avoid falling off. Moreover, in a state where the heat storage agent stored in the second storage unit is not solidified, it is possible to avoid the object to be stored from being cooled too much by storing the solidified heat storage agent in the first storage unit. By storing the solidified heat storage agent in the third storage unit, the object to be stored can be kept at a desired temperature in the freezing area. Thus, if the solidified heat storage agent is stored in either the first storage unit or the third storage unit according to the use environment without taking out the heat storage agent stored in the second storage unit. For this reason, when the storage object is stored at a constant temperature using the solidified heat storage agent and the non-solidified heat storage agent, the positional relationship of these two heat storage agents with respect to the storage object does not become wrong.

  Further, in the case where the surface of the third storage portion opposite to the second storage portion is formed of a breathable sheet, the third storage portion is stored in the second storage portion or the third storage portion. When it is used without storing the heat storage agent in the third storage part in order to avoid the cold air and heat of the heat storage agent being easily transmitted to the storage object and its surroundings, and to prevent the storage object from being cooled too much The third storage portion can be made less bulky.

It is an external appearance perspective view which shows the other structural example of the thermal storage agent accommodation tool used for the storage container shown in FIG.

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

  FIG. 1 is an external perspective view showing an embodiment of the storage container of the present invention. 2A and 2B are diagrams showing the configuration of the heat storage agent storage device 2 shown in FIG. 1, wherein FIG. 2A is an external perspective view, and FIG. 2B is a diagram showing the heat storage agent storage device 2 attached to the lid 3 of the storage container 1. FIG.

  As shown in FIG. 1, the storage container 1 in the present embodiment has a bottom portion 6 and four side wall portions 4 standing on the bottom portion 6, and a region surrounded by the bottom portion 6 and the side wall portion 4 is stored. A storage space 5 is provided for storing objects. The lid 3 is attached to the opposite side of the storage space 5 from the bottom 6 by a hinge or the like so that the object to be stored can be taken in and out with the lid 3 opened, and the lid 3 is closed. Thus, the article to be stored is stored at a desired temperature. In addition, each of the surface by the side of the storage space 5 of the bottom part 6, the side wall part 4, and the cover part 3 of the storage container 1 becomes an inner wall surface in this invention. A heat storage agent container 2 is attached to the lid 3 on the surface on the storage space 5 side, that is, on the ceiling surface of the storage container 1.

  As shown in FIG. 2, the heat storage agent container 2 is made of aluminum or the like, and is configured by overlapping two flexible separator sheets 11 and 21 and a mesh-like front sheet 31 having air permeability. ing.

  The separator sheets 11 and 21 are sealed to each other at their four sides, so that an area surrounded by these four sides between the two separator sheets 11 and 21 is the second storage. It is part 20. A heat storage agent 40 is stored in the storage unit 20. The heat storage agent 40 is stored in the storage unit 20 so as not to be removed because the separator sheets 11 and 21 are sealed to each other at the four sides.

  The separator sheet 11 is attached to the lid portion 3 by fixing the fixing portion 12 to the inner wall surface of the lid portion 3 on the side of the accommodation space 5. Between the cover 11 and the cover 3, a first storage portion 10 is formed with one side other than the fixing portion 12 of the separator sheet 11 as an opening.

  The front sheet 31 is arranged so as to cover the separator sheets 11 and 21, and an area along the three sides becomes a fixing portion 32, and the fixing portion 32 is fixed to the inner wall surface of the lid portion 3 on the accommodation space 5 side. Is attached to the lid portion 3, and a third storage portion 30 is formed between the front sheet 11 and the separator sheet 21 with one side other than the fixing portion 32 of the front sheet 31 as an opening. . Note that the sides that are the openings of the storage portions 10 and 30 of the separator sheet 11 and the front sheet 31 are sides that overlap each other.

  The separator sheet 11 and the front sheet 31 are attached to the lid portion 3 by stitching or the like at the fixing portions 12 and 32 of the separator sheet 11 and the front sheet 31, and the separator sheet 11 and the front sheet 31 are attached to the lid portion 3. It is impossible to remove from.

  As described above, the heat storage agent storage device 2 including the three storage units 10, 20, and 30 is configured by attaching the heat storage agent storage device 2 to the lid 3. And this thermal storage agent storage part is installed in the inner wall surface of the cover part 3 of the storage container 1 so that attachment or detachment is impossible, the storage part 10, the storage part 20 in which the thermal storage agent 40 was stored so that it could not be taken out, and the storage part 30 are arranged in this order from the inner wall surface side of the lid portion 3.

  Below, the usage method of the storage container 1 comprised as mentioned above and the effect | action produced in that case are demonstrated.

  First, a method of use and an operation in the case where a storage object to be prevented from being cooled too much is accommodated in the storage container 1 will be described.

  FIG. 3 is a diagram for explaining a method of use and an action in the case of storing an object to be stored that is desired to avoid being overcooled in the storage container 1 shown in FIG. 1, and shows a longitudinal sectional view of the storage container 1. .

  When the storage container 1 shown in FIG. 1 stores an object to be stored that is not to be cooled too much, the solidified heat storage agent 50 is stored in the storage unit 10 and used as shown in FIG. Since the storage unit 10 has an opening on one side other than the fixing unit 12 of the separator sheet 11, the heat storage agent 50 can be stored in the storage unit 10 from this opening. Then, the non-solidified heat storage agent 40 stored in the storage unit 20 is interposed between the solidified heat storage agent 50 and the article 7 to be stored.

And since the thermal storage agent 50 is solidified and the thermal storage agent 40 is not solidified, the thermal storage agent 40 is cooled by the thermal storage agent 50 by exchanging the thermal energy J ₁ between the thermal storage agents 40 and 50. Then, the article 7 is cooled by the heat storage agent 40 by exchanging the thermal energy J ₂ between the cooled heat storage agent 40 and the article 7.

  In this way, the article 7 is indirectly cooled by the solidified heat storage agent 50 via the heat storage agent 40 that has not solidified. Thereby, the temperature of the article 7 does not become lower than the freezing point of the heat storage agent 40 that has not solidified, and the article 7 can be prevented from being cooled too much.

  At this time, no heat storage agent is stored in the storage unit 30, but the front sheet 31 is mesh-like, so that cold air and heat due to the temperature of the heat storage agent 40 are easily transmitted to the article 7 and its surroundings. The storage unit 30 is less likely to be bulky.

  In addition, the separator sheets 11 and 21 are sealed to each other at the four sides thereof, and the separator sheet 11 and the front sheet 31 are respectively provided with fixing portions 12 and 32 along the three sides of the storage space 5 of the lid portion 3. Since it is attached to the lid 3 by being fixed to the inner wall surface on the side, it is ensured that the heat storage agent storage device 2 storing the heat storage agents 40 and 50 is prevented from falling off the ceiling of the storage container 1. can do.

  In addition, the heat storage agent 40 does not have a fixed form in a state where it is not solidified. Therefore, there exists a possibility that the thermal storage agent 40 may fall out of the thermal storage agent storage device 2 unintentionally due to vibration or the like. However, since the heat storage agent 40 that has not solidified is stored in the storage unit 20 so as not to be taken out, the heat storage agent 40 is not unintentionally dropped from the heat storage agent storage device 2.

  Next, a description will be given of a method of use and an action in the case where the object to be stored is kept at a desired temperature in the freezing area.

  FIG. 4 is a view for explaining a method of use and an action in the case where the object stored in the storage container 1 shown in FIG. Indicates.

  In the refrigeration zone, when keeping the object to be stored in the storage container 1 shown in FIG. 1 at a desired temperature, the solidified heat storage agent 60 is stored in the storage unit 30 and used as shown in FIG. Since the storage part 30 has an opening on one side other than the fixing part 32 of the front sheet 31, the heat storage agent 60 can be stored in the storage part 30 from this opening. Then, although the non-solidified heat storage agent 40 stored in the storage unit 20 is present, the heat storage agent 40 exists on the opposite side of the solidified heat storage agent 60 from the article 7, so that the solidified heat storage agent 40 is present. Between the agent 60 and the article 7 to be stored, a non-solidified heat storage agent is not interposed.

  The temperature of the article 7 can be maintained at a temperature corresponding to the freezing point of the heat storage agent 60 by directly exchanging the thermal energy J between the solidified heat storage agent 60 and the article 7. At this time, since the front sheet 31 is a breathable mesh, cold air and heat due to the temperature of the solidified heat storage agent 60 are easily transmitted to the article 7 and its surroundings. Further, since the heat storage agent 40 that has not solidified is cooled and solidified by the cold air from the heat storage agent 60 that has solidified, the article 7 is kept at a constant temperature using the two heat storage agents 40 and 50 that have solidified. Thus, the heat retention time can be extended as compared with the case where one heat storage agent is used.

  In the same manner as described above, the separator sheets 11 and 21 are sealed to each other at the four sides, and the separator sheet 11 and the front sheet 31 are respectively fixed to the lid portion 3 by fixing portions 12 and 32 along the three sides. Since it is attached to the lid 3 by being fixed to the inner wall surface on the side of the storage space 5, the heat storage agent storage tool 2 storing the heat storage agents 40, 50 falls off the ceiling of the storage container 1. It can be avoided reliably.

  As described above, in the state where the heat storage agent 40 stored in the storage unit 20 is not solidified, it is possible to prevent the article 7 from being cooled too much by storing the solidified heat storage agent 50 in the storage unit 10. By storing the solidified heat storage agent 60 in the storage unit 30, the article 7 can be maintained at a desired temperature in the freezing area. In this way, the solidified heat storage agent may be stored in either the storage unit 10 or the storage unit 30 according to the use environment without taking out the heat storage agent 40 stored in the storage unit 20. The positional relationship of the two heat storage agents with respect to the article 7 does not become incorrect.

  In this embodiment, the front sheet 31 is described as an example of a mesh, but the front sheet 31 may be made of the same material as that of the separator sheets 11 and 21. However, if the front sheet 31 is made of a breathable sheet such as a mesh, as described above, the cool air and heat of the heat storage agent stored in the storage units 20 and 30 may cause the stored object and its surroundings. In addition, the storage unit 30 can be made less bulky when used without storing the heat storage agent in the storage unit 30 in order to avoid the object to be stored being cooled too much. In that case, it is good also as a structure which hold | maintains the thermal storage agent accommodated in the accommodating part 30 using a wide band etc. instead of covering the one surface on the opposite side to the accommodating part 20 of the accommodating part 30 with the front sheet | seat 31. . However, the heat storage agent can be easily stored in the storage unit 30 by using the mesh-shaped front sheet 31.

  Moreover, in this form, although the case where the heat storage agent storage tool 2 was attached to the surface on the storage space 5 side of the lid 3 of the storage container 1 was described as an example, the heat storage agent storage tool 2 is a storage container. The storage container 1 may be attached to any one of the bottom 6, the side wall 4, and the surface of the lid 3 on the storage space 5 side. When the heat storage agent storage device 2 is attached to the lid portion 3, the force of gravity is applied to the heat storage agent storage device 2 in the direction opposite to the lid portion 3. However, even when the heat storage agent storage device 2 is attached to a portion other than the lid 3, when the storage container 1 falls or when the storage container 1 is subjected to strong vibration, the heat storage agent storage device 2. Is effectively prevented from falling off from the inner wall surface of the storage container 1. In addition, the object to be stored is not opened / closed to / from the storage container 1 by opening / closing the lid 3 as in the present embodiment, but the object to be stored is stored by opening / closing one surface of the side wall 4. In the case of a configuration that is inserted into and withdrawn from the storage unit 1, the possibility that the heat storage agent storage device 2 is dropped from the storage container 1 due to vibration at the time of opening and closing the side wall portion 4, a change in the inclination of the side wall portion 4, and the like increases. However, since the heat storage agent storage tool 2 is installed on the inner wall surface of the side wall portion 4 so as not to be detachable, an effect of avoiding the heat storage agent storage tool 2 from falling off can be obtained.

  Further, in this embodiment, the separator sheets 11 and 21 are sealed to each other at the four sides thereof, so that the heat storage agent 40 is stored in the storage unit 20 so as not to be taken out. A part of which can be opened and closed such as a fastener may be provided in a part, and the heat storage agent 40 may be taken out of the storage unit 20 through the outlet. Even in that case, the heat storage agent 40 may be unintentionally dropped from the heat storage agent storage device 2 due to vibration or the like by closing the take-out port in a state where the heat storage agent 40 is stored in the storage unit 20. Is avoided.

  Further, in this embodiment, each of the separation sheet 11 and the front sheet 31 has three storages by fixing the fixing parts 12 and 32 along the three sides to the inner wall surface of the cover part 3 on the storage space 5 side. The heat storage agent storage part which comprises the part 10,20,30 is installed in the inner wall surface of the cover part 3 of the storage container 1 so that attachment or detachment is impossible, and, thereby, the heat storage agent storage tool 2 in which the heat storage agent 40,50 was stored. Can be surely avoided from falling off the ceiling of the storage container 1, but the heat storage agent storage part comprising the three storage parts 10, 20, 30 is the inner wall surface of the lid part 3 of the storage container 1. Even if it is the case where it is set as the structure installed so that attachment or detachment is possible, it can avoid reliably that the thermal storage agent storage tool 2 in which the thermal storage agents 40 and 50 were accommodated falls from the ceiling of the storage container 1. FIG. The effect of being able to do is difficult to obtain About the effect that the positional relationship of these two heat storage agents with respect to the storage object does not become wrong when the storage object is stored at a constant temperature using the solidified heat storage agent and the non-solidified heat storage agent. Can be obtained in the same manner as described above.
