JP 2002-145342 A

  By the way, when the height of the “support wall” is relatively low, for example, when it is less than half of the height of the specific article accommodated in the in-wall housing, it is specified when transporting the box-type container. There is a concern that the article may be tilted inward of the container, and depending on the case, the specific article may fall out of the container inside the wall or adversely affect the contents stored in the box-type container. .

  On the other hand, when the height of the “support wall portion” is relatively high, for example, when the height of the specific article accommodated in the in-wall accommodating portion is higher, it is difficult to take out the specific article from the in-wall accommodating portion. There is a fear.

  The present invention has been made in order to solve the above-described problems and the like, and its purpose is to prevent a situation in which it is difficult to take out a specific article from the in-wall housing section, while preventing the in-wall housing section. Another object of the present invention is to provide a box-type container that can stabilize the state of accommodation of a specific article.

  In the following, each means suitable for solving the above-mentioned purpose will be described in terms of items. In addition, the effect etc. peculiar to the means to respond | correspond as needed are added.

Means 1. In a box-shaped container that includes a substantially rectangular plate-shaped bottom wall portion and side wall portions that extend upward from each side portion of the bottom wall portion, and can store articles in an inner storage space,
On the inner surface side of the side wall portion, an in-wall accommodating portion capable of accommodating a substantially flat specific article along the inner surface of the side wall portion is formed,
A support wall portion that supports the inner surface of the specific article stored in the inner wall storage portion and restricts displacement toward the inner side of the container;
It is a configuration that allows the specific article to be taken in and out from the upper side with respect to the in-wall housing portion,
The support wall portion can support a left support wall portion capable of supporting the left side portion of the specific article accommodated in the in-wall accommodation portion and a right side portion of the specific article accommodated in the in-wall accommodation portion. A right support wall,
One of the left support wall and the right support wall is formed to a position higher than the other, and the other formed to the high position is accommodated in the in-wall accommodating portion. The upper end of the specific article is substantially the same height, or is formed at a position higher than the upper end of the specific article housed in the in-wall housing section .
The in-wall housing portion is
The left side portion is defined by a left side regulation surface that supports the left side surface of the specific article accommodated in the in-wall accommodation unit and regulates the displacement to the left side, and
The right side portion is defined by the right side regulation surface that supports the right side surface of the specific article accommodated in the in-wall housing portion and regulates the displacement to the right side,
One of the left regulating surface and the right regulating surface has an inclination angle substantially the same as or close to the vertical direction with respect to the bottom surface of the in-wall housing portion, and the left regulating surface and the The other of the right side regulation surfaces has an inclined surface that is looser than the one,
Corresponding to the left and right side portions of the in-wall housing portion in the lateral width direction of the side wall portion in which the in-wall housing portion is formed,
Of the left support wall portion and the right support wall portion, the height substantially the same as the upper end portion of the specific article housed in the in-wall housing portion, or the specific body housed in the in-wall housing portion. One support wall formed to a position higher than the upper end of the article;
Of the right-side restriction surface and the right-side restriction surface, one restriction surface is formed which is substantially the same as the vertical direction with respect to the bottom surface of the in-wall housing portion, or has an inclination angle close thereto,
Corresponding to the left and right other side of the in-wall housing part in the lateral width direction of the side wall part in which the in-wall housing part is formed,
The other supporting wall portion and a loose inclined surface which is the other regulating surface are formed;
The box-shaped container characterized in that the other supporting wall portion and the loose inclined surface which is the other regulating surface have the same height .

  According to the means 1, one of the left support wall portion and the right support wall portion that restricts the displacement of the specific article accommodated in the in-wall accommodation portion toward the inside of the container (hereinafter referred to as “high wall portion”). ) Is approximately the same as the height of the specific article accommodated in the in-wall accommodating portion, or higher than the height of the specific article, so that the tilt displacement of the specific article into the container at the high wall portion is reduced. It can prevent more reliably. Therefore, it is possible to avoid a situation in which the specific article is tilted inward of the container or dropped into the storage space and adversely affects the stored items stored in the storage space.

  Further, the other of the left support wall portion and the right support wall portion (hereinafter referred to as “low wall portion”) is configured to be lower than the high wall portion. Thereby, it becomes relatively easy to pick up (easy to grasp) the specific article accommodated in the in-wall accommodating part from the low wall side, and the specific article is easily taken out, and the specific article is accommodated in the in-wall accommodating part. Workability can also be improved.

  In addition, “the other of the left support wall portion and the right support wall portion that is formed lower than the one (high wall portion) (the low wall portion) is the specific part accommodated in the in-wall housing portion. It may be formed lower than the upper end portion of the article. In this case, the range including the side part of the specific article is exposed inside the container above the low wall part. Furthermore, since there is no support wall part that regulates the displacement of the upper part of the specific article into the container contents on the low wall part side, the upper part of the specific article exposed above the low wall part is brought closer to the container inner side. By tilting the specific article within the inner container, the outer surface of the specific article is separated from the surface of the inner container defining the inner container as much as possible. A space for inserting a finger between them can be secured as wide as possible. Therefore, it is possible to make it easier to pick the specific article accommodated in the in-wall accommodating portion, and it is possible to further improve the workability of taking in and out the specific article.

Further , according to the means 1 , the left-side regulating surface and the right-side regulating surface that regulate the displacement in the lateral width direction (left-right direction) of the side wall portion of the specific article housed in the in-wall housing portion are substantially the same as the direction perpendicular to the bottom surface Or, it is possible to more reliably prevent a specific article housed in the wall housing part from swinging to the left and right as a result of being inclined at an angle close to that (hereinafter referred to as “steep slope”). can do.

  In addition, by using the other side (hereinafter referred to as “slow slope”) having a gentler inclination angle than one of the left side regulation surface and the right side regulation surface, the space formed above the gentle slope is utilized. Rotating the specific article accommodated in the in-wall accommodating portion to make it easier to take out (easy to grasp), or the part of the specific article that the operator is holding and the center of gravity of the specific article are vertical It is possible to take out the specific article while rotating it in such a direction as to line up on the line. For this reason, in order to take out the specific article from the interior housing part, after adopting a configuration in which the specific article can only be pulled out in the vertical direction with the same posture after picking the vicinity of the corner portion of the specific article Compared to (when both the left and right regulation surfaces are steep slopes), it is possible to improve the ease with which a specific article is taken out from the interior storage section and the ease with which it can be stored in the interior storage section. it can.

In addition, “the inclination angle of the other side (slow slope) of the left side regulation surface and the right side regulation surface, which is looser than the one (steep slope), is that the specific article is the one (steep slope) in the inner wall accommodating portion. It may be set based on the radius of rotation of the specific article so that it can be rotated around the contact portion with the center). Further, by setting the inclination angle of the steep slope to about 80 to 90 degrees and the inclination angle of the gentle slope to about 60 to 75 degrees, the effect of the means 1 can be more reliably achieved.

Further , according to the means 1 , the taller one of the left support wall part and the right support wall part ("high wall part") corresponding to the left and right side parts of the in-wall housing part, and the left regulation surface And the one with the steep inclination angle ("steep slope") among the right side regulation surfaces. In other words, corresponding to the left and right other side portions of the in-wall housing portion, the shorter one of the left support wall portion and the right support wall portion (“low wall portion”), the left restriction surface, and the right restriction surface The one having a gentle inclination angle (“slow slope”) is formed. For this reason, rotation of a specific article that allows the lower corner of the low wall side to pass through the space above the gentle slope with the contact portion between the upper corner of the high wall side and the steep slope as the center of rotation. Operation will be allowed. Therefore, when the specific article is picked up in the upper part of the low wall portion and lifted in the vertical direction as it is, the specific article is gripped by the operator with its own weight. Centering on the part that has been made, the part gripped by the operator and the center of gravity of the specific article rotate relatively smoothly in the in-wall housing part in a direction that aligns in the vertical direction. As a result, among the specific articles stored in the inner wall storage section, the part above the low wall portion is picked, and the specific article is rotated while the specific article is rotated by lifting the specific article in a substantially vertical direction. It can be removed relatively smoothly from the inner housing.

By the way, if the low wall and the steep slope are formed on the same side of the left and right (the high wall and the gentle slope are formed on the same side of the left and right), the specified article is picked above the low wall. If the specific article is lifted in the vertical direction as it is, the rotation of the specific article is hindered by the steep slope. In this case, since friction is generated between the specific article and the steep slope, there is a concern that it may be relatively difficult to take out, or the specific article or the steep slope may be damaged and dirt or the like may be easily attached. Accordingly, by forming the low wall portion and the gentle slope on the same left and right sides as in the present means 1 , it is possible to improve the workability when taking out the specific article from the in-wall housing portion. Also, when the specific article is stored in the inner wall storage portion, the specific article is placed in the wall while bringing the specific article close to the inner wall storage portion from the low wall side and guiding the lower end of the specific article to the gentle slope. It can be accommodated in the accommodating portion, and workability can be improved.
In the means 1, the side wall portion may have a certain height.

  In addition, when the high wall part and the gentle slope are formed on the same side of the left and right, the specific part should be supported unless the projecting length from the gentle slope is increased for the upper part of the high wall part. Will not be able to. In this case, there is a concern that the tip portion in the protruding direction from the gentle slope of the high wall portion may be relatively easily damaged, and in particular, the upper corner portion of the high wall portion is more accommodating than the upper corner portion of the low wall portion. This concern becomes even more conspicuous in combination with the fact that there are many opportunities for contact with articles and the like that are put in and out. In this respect, by forming the high wall and the steep slope on the same left and right sides as in this means, the specific article can be reliably supported even if the protruding length from the steep slope at the top of the high wall is shortened. Can alleviate such concerns.

  Hereinafter, an embodiment will be described with reference to the drawings. As shown in FIGS. 1 and 2, the box-shaped container 1 has a substantially square box shape that opens upward, and includes a container body 2 having a storage space 3 in which articles can be stored, and an opening of the container body 2. The lid member 4 can be closed. The container body 2 has a substantially rectangular plate-like bottom wall 7, a long side wall 8 extending upward from a pair of long sides opposed to the bottom wall 7, and a bottom wall 7. A short side wall 9 extending upward from each of the pair of short sides is provided.

  The container body 2 and the lid member 4 of this embodiment are each made of foamed polypropylene. For this reason, compared with what is comprised with a non-foaming material, the thickness is comprised thickly as a whole, and a level | step difference etc. are formed by changing thickness. Furthermore, the box-type container 1 of the present embodiment is used for transporting and storing foods that require temperature control, and on the inner surface side of one long side wall portion 8, In-wall accommodating part 11 which can accommodate etc. is formed.

  As shown in FIG. 2 to FIG. 5 and the like, the in-wall accommodating portion 11 expands a range including the central portion in the lateral width direction on the inner surface of the long side wall portion 8 to the outside, and a space that can be expanded. It is formed so as to open upward. In the present embodiment, a cold insulating agent 5 as a specific member having a substantially flat plate shape (a relatively thin substantially rectangular parallelepiped shape) is erected sideways along the inner surface of the long side wall portion 8 in the in-wall housing portion 11. In such a state (a state in which the long side portion is supported by the bottom surface).

  Further, the long side wall portion 8 in which the in-wall storage portion 11 is formed supports the inner surface of the container 5 of the cold-retaining agent 5 stored in the in-wall storage portion 11 and is displaced toward the inner side of the container. A support wall portion 12 is provided to prevent this. The support wall portion 12 is accommodated in the wall so that the inner surface of the long side wall portion 8 adjacent to the left side of the in-wall housing portion 11 is extended to the in-wall housing portion 11 side when viewed from the inside of the container body 2. The left support wall 13 (see FIG. 3) that protrudes from the left regulating surface 15 that defines the left side of the portion 11 and the inner surface of the long side wall 8 that is adjacent to the right side of the in-wall housing 11 A right support wall portion 14 (see FIG. 4) is provided so as to protrude from the right-side regulating surface 16 that defines the right side portion of the in-wall housing portion 11 so as to extend toward the housing portion 11 side.

  Further, as shown in FIG. 5 and the like, in the present embodiment, the left support wall portion 13 is substantially the same height as the upper end portion of the cold-retaining agent 5 housed in the in-wall housing portion 11 from the bottom surface of the in-wall housing portion 11. It is formed to the position. On the other hand, the right support wall portion 14 is lower than the left support wall portion 13 and extends from the bottom surface of the in-wall housing portion 11 to a height position that is almost half of the cold insulation agent 5 housed in the in-wall housing portion 11. Is formed. In addition, as shown in FIG. 3 and the like, the bottom surface of the storage space 3 of the container body 2 and the bottom surface of the in-wall storage portion 11 are flush with each other.

  Moreover, as shown in FIG. 6 etc., the position shift in the lateral width direction (left-right direction) of the long side wall part 8 of the cold insulation agent 5 accommodated in the in-wall accommodation part 11 is arranged opposite to the left side surface of the cold insulation agent 5. This is prevented by the left regulation surface 15 and the right regulation surface 16 disposed opposite to the right side surface of the cooling agent 5. In the present embodiment, the left-side regulating surface 15 and the right-side regulating surface 16 are configured such that the inclination with respect to the bottom surface of the in-wall housing portion 11 is different. More specifically, the left regulation surface 15 is substantially orthogonal to the bottom surface of the in-wall housing portion 11 and is 89 degrees in this embodiment. On the other hand, the right regulating surface 16 is inclined more gently than the left regulating surface 15 and is 70 degrees in the present embodiment. The left restricting surface 15 and the right restricting surface 16 are inclined in directions opposite to each other so that the width of the in-wall housing portion 11 is gradually expanded upward in the left-right direction. In addition, the distance between the lower end portion of the left regulating surface 15 and the lower end portion of the right regulating surface 16 is substantially the same as the lateral width of the cooling agent 5.

  Further, as shown in FIGS. 3 to 5 and the like, in the present embodiment, the height of the left support wall portion 13 and the height of the left regulating surface 15 coincide with each other, and the height of the right support wall portion 14 and the right side The height of the restricting surface 16 matches. That is, in the present embodiment, the upper end of the right support wall portion 14 and the right regulating surface 16 in the portion on the right side of the long-side side wall portion 8 in which the in-wall housing portion 11 is formed. The inner surface (accommodating space 3) of the portion located above the portion is expanded outward to the same extent as the in-wall accommodating portion 11. Further, in the long side wall portion 8 in which the in-wall housing portion 11 is formed, the portion adjacent to the left regulation surface 15 is positioned above the upper ends of the left support wall portion 13 and the left regulation surface 15. The inner surface (accommodating space 3) of the part is expanded outward as much as the in-wall accommodating portion 11.

  In addition, as shown in FIGS. 3, 7, etc., the left support wall 13 and the right support wall 14 are formed so that the surfaces facing the container outer side that define the in-wall housing part 11 gradually become upward. Inclined toward the inward side. Furthermore, the surface facing the container inner side among the surfaces defining the in-wall housing portion 11 is gradually inclined upward toward the container outward. With these configurations, the width of the in-wall housing portion 11 in the thickness direction of the long side wall portion 8 becomes wider as it becomes an upper portion, and it becomes easier to put the refrigerant 5 in and out of the in-wall housing portion 11. Yes.

  Further, as shown in FIG. 3, the protruding length of the left support wall 13 from the left restricting surface 15 gradually increases as it becomes a lower portion, and the protruding direction of the left support wall 13 from the left restricting surface 15. The inclination of the leading edge is gentler than the inclination of the left regulating surface 15. On the other hand, as shown in FIG. 4, the protruding length of the right support wall portion 14 from the right restriction surface 16 is substantially constant in any part in the vertical direction, and the right restriction surface 16 of the right support wall portion 14. The inclination of the leading edge in the protruding direction from the projection is substantially the same as the inclination of the right regulating surface 16. Further, as shown in FIG. 5, the distance between the lower end portion of the left support wall portion 13 and the lower end portion of the right support wall portion 14 is longer than the length of 70% of the lateral width of the cooling agent 5. . Thereby, most of the surface inside the container of the cold-retaining agent 5 accommodated in the in-wall accommodating portion 11 is exposed to the accommodating space 3, and the cooling efficiency is improved.

  As a method of using the box-shaped container 1 configured as described above, the lid member 4 is opened, and the cold-retaining agent 5 that has been cooled from the upper side with respect to the in-wall accommodation portion 11 is accommodated. And stores items that require refrigeration. Then, by closing the lid member 4, the left support wall portion 13 and the right support wall portion 14 are placed between the in-wall storage portion 11 in which the cooling agent 5 is stored and the storage space 3 in which the article is stored. Heat exchange is performed between and through the communication space above the right support wall 14, and articles can be transported while keeping the storage space 3 at a low temperature.

  Further, when the cold insulation agent 5 is taken out from the in-wall housing portion 11 after the box-shaped container 1 is used, first, the upper right portion exposed to the inside of the container above the right support wall portion 14 of the cold insulation agent 5 is first removed. pinch. At this time, by tilting the cryogen 5 within the inner housing part 11 so that the upper right part of the cryogen 5 is brought closer to the inside of the container, the outer surface of the cryogen 5 and the inner container 11 are separated. A gap is formed between the surface to be defined and the surface facing the inside of the container, and a hand is inserted into the gap to pinch the cold-retaining agent 5. After picking up the upper right part of the cooling agent 5, it pulls up in the substantially vertical direction as it is. As a result, as shown in FIG. 8, the coolant 5 is rotated relatively smoothly in the in-wall housing portion 11 by the weight of the coolant 5 itself around the part left untouched by the operator, and finally In this case, the position of the cryogen 5 that is held by the operator and the center of gravity of the cryogen 5 are rotated until they are aligned in the vertical direction, and the cryogen 5 is taken out from the in-wall housing 11. The Rukoto.

  As described above in detail, according to the present embodiment, the in-wall housing portion 11 capable of housing the cooling agent 5 is provided on the inner surface side of the long side wall portion 8. Thereby, conveyance, storage, etc. can be carried out, keeping the articles | goods accommodated in the accommodation space 3 cold. Further, of the left support wall 13 and the right support wall 14 that regulate the displacement of the cryogen 5 stored in the wall storage 11 toward the inside of the container, the left support wall 13 (high wall) is provided. By making the height approximately the same as the height of the cooling agent 5 accommodated in the in-wall accommodating portion 11, the left supporting wall portion 13 can more reliably prevent the inclining displacement of the cooling agent 5 inward of the container. it can. Accordingly, it is possible to avoid a situation in which the cold insulating agent 5 is tilted inward of the container or dropped into the storage space 3 to adversely affect the stored items stored in the storage space 3.

  Of the left support wall portion 13 and the right support wall portion 14, the right support wall portion 14 (low wall portion) is lower than the left support wall portion 13, and the cold insulating agent 5 accommodated in the in-wall accommodating portion 11. It is almost half the height. Thereby, the upper right part of the cold insulating agent 5 is exposed to the inside of the container above the right support wall portion 14, and the cold insulating agent 5 is easily picked up. Accordingly, it is possible to easily take out the cold insulation agent 5 and to improve the workability of accommodating the cold insulation agent 5 in the in-wall accommodation portion 11. Furthermore, on the right support wall 14 side, since there is no wall portion that restricts the displacement of the cryogen 5 into the container contents at the upper right portion, the upper right portion of the cryogen 5 exposed above the right support wall 14 is By inclining the cryogen 5 in the in-wall housing part 11 so as to approach the inside of the container, the inside of the container out of the surface on the container outside side of the cryogen 5 and the surface defining the in-wall housing part 11 The space facing the side can be separated as much as possible, and a space for inserting a finger between both surfaces can be secured as much as possible. Therefore, it is possible to make it easier to pick the cold-retaining agent 5 accommodated in the in-wall accommodating portion 11, and it is possible to further improve the workability for putting in and out the cold-retaining agent 5.

  In addition, while forming the right support wall part 14 as low as possible and separating the left support wall part 13 and the right support wall part 14 as much as possible, the communication area between the in-wall storage part 11 and the storage space 3 is expanded. Therefore, the heat exchange between the in-wall housing portion 11 and the housing space 3 can be performed smoothly.

  Of the left-side regulating surface 15 and the right-side regulating surface 16 that regulate displacement in the lateral width direction (left-right direction) of the long-side side wall portion 8 of the cold-retaining agent 5 housed in the in-wall housing portion 11, The left regulating surface 15 (steep slope) having substantially the same inclination angle (89 degrees in this example) can prevent displacement to at least the left side, and is stored in the in-wall housing portion 11. It is possible to more reliably prevent such a situation that 5 is shaken by swinging left and right greatly.

  Furthermore, the right-side regulating surface 16 (slow slope) has a relatively slanting angle (70 degrees in this example) as compared with the left-side regulating surface 15, thereby forming a space formed above the right-side regulating surface 16. The cold-retaining agent 5 accommodated in the in-wall accommodating part 11 can be taken out while rotating. That is, in this embodiment, when taking out the cooling agent 5 from the in-wall housing portion 11, the right side from the center of gravity of the cooling agent 5 exposed to the inside of the container above the right regulation surface 16 of the cooling agent 5. The shifted upper right part will be picked, but when the coolant 5 is lifted upward, the part of the coolant 5 that the operator is holding and the center of gravity of the coolant 5 are aligned on the vertical line. The cooling agent 5 can be taken out while rotating. For this reason, in order to take out the cold insulating agent 5 from the in-wall housing portion 11, after adopting a configuration in which the cold insulating agent 5 can only be pulled out in the same posture after the cold insulating agent 5 is picked ( Compared to the case where both the left regulation surface 15 and the right regulation surface 16 are steep slopes), the easiness of taking out the refrigerant 5 from the in-wall housing portion 11 and the ease of housing in the in-wall housing portion 11 are improved. Can be achieved.

  In particular, in the present embodiment, the left support wall 13 corresponding to the left side of the in-wall housing portion 11 is configured to be taller than the right support wall 14, and the left side of the in-wall housing portion 11 is also the same. The left-side restricting surface 15 corresponding to is inclined more steeply than the right-side restricting surface 16. On the other hand, the right support wall 14 and the right regulating surface 16 corresponding to the right side of the wall inner peripheral wall 11 are relatively short and formed with a gentle slope. For this reason, the cooler 5 is rotated while passing the lower right corner of the cooler 5 through the space above the right restrictor 16 around the contact portion between the upper left corner of the cooler 5 and the left restrictor 15. Such an operation is allowed. Therefore, when the upper right portion of the cold insulating agent 5 exposed above the short right support wall portion 14 is picked and the cold insulating agent 5 is lifted in a substantially vertical direction as it is, the cold insulating agent 5 is given to the operator by its own weight. With the gripped part as the center, the part gripped by the operator and the center of gravity of the coolant 5 are rotated relatively smoothly in the in-wall housing 11 so that the center of gravity of the coolant 5 is aligned in the vertical direction. . As a result, among the cold-retaining agents 5 housed in the in-wall housing 11, the upper-right part of the cold-retaining agent 5 is picked and the upper-right part of the cold-retaining agent 5 is lifted in the substantially vertical direction as it is. Meanwhile, the cold insulating agent 5 can be removed relatively smoothly from the in-wall housing portion 11.

  By the way, the shorter one of the left support wall portion 13 and the right support wall portion 14 (low wall portion) and the one with the steep inclination angle (steep slope) of the left restriction surface 15 and the right restriction surface 16 are left and right. When formed on the same side (the high wall portion and the gentle slope are formed on the left and right sides), the cold insulation agent 5 is picked above the low wall portion, and the cold insulation agent 5 is lifted in the vertical direction as it is. If only, the rotation of the cooling agent 5 is hindered by the steep slope. In this case, since friction is generated between the cooling agent 5 and the steep slope, there is a concern that it may be relatively difficult to take out, or the cooling agent 5 or the steep slope may be damaged and dirt or the like may be easily attached. The Therefore, as in the present embodiment, by forming the low wall portion and the gentle slope on the same left and right sides, it is possible to improve the workability when taking out the cooling agent 5 from the in-wall housing portion 11. . Further, when the cold insulation agent 5 is accommodated in the in-wall housing portion 11, the cold insulation agent 5 is brought close to the in-wall housing portion 11 from the low wall portion (right support wall portion 14) side, and the lower end portion of the cold insulation agent 5 is The cold-retaining agent 5 can be accommodated in the in-wall accommodating portion 11 while being guided by the gentle slope (the right regulating surface 16), and workability can be improved.

  In addition, when the high wall portion and the gentle slope are formed on the same left and right sides, the cold insulator 5 is supported unless the protrusion length from the gentle slope is increased for the upper portion of the high wall portion. It becomes impossible to do. In this case, there is a concern that the tip portion in the protruding direction from the gentle slope of the high wall portion may be relatively easily damaged, and in particular, the upper corner portion of the high wall portion is more accommodating than the upper corner portion of the low wall portion. This concern becomes even more conspicuous in combination with the fact that the number of opportunities for contact with articles and the like that are put into and out of 3 is likely to increase. In this respect, as in the present embodiment, the high wall portion and the steep slope are formed on the same left and right sides, so that the cold insulating agent 5 is reliably supported even if the protruding length from the steep slope at the top of the high wall portion is shortened. And can dispel such concerns.

  Even in the case of adopting a configuration in which the low wall portion and the steep slope coincide with each other, the operator holds the cryogen 5 by lifting it obliquely upward along the steep slope. Can be taken out relatively smoothly while rotating the cold insulation agent 5 so that the center of the cold insulation agent 5 and the center of gravity of the cold insulation agent 5 are aligned on the vertical line, but the point regarding the angle and timing of lifting the cold insulation agent 5 is obtained. There is a need. On the other hand, according to this embodiment, even an operator who is not accustomed to taking in and out of the cooling agent 5 can surely enjoy the operational effect that the cooling agent 5 is easily taken in and out.

  In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other application examples and modification examples not illustrated below are also possible.

  (A) In the above embodiment, of the left support wall 13 and the right support wall 14, the height of the higher left support wall 13 is the height of the cold insulating agent 5 stored in the in-wall storage 11. However, it may be configured to be higher than the height of the coolant 5. Moreover, in the said embodiment, the height of the cold support agent 5 accommodated in the in-wall accommodating part 11 is the height of the lower right support wall part 14 among the left support wall part 13 and the right support wall part 14. However, it is sufficient that the height is lower than the left support wall 13. However, the height of the right support wall portion 14 is configured to be lower than the height of the cold insulation agent 5 accommodated in the in-wall accommodation portion 11 in order to make it easier to take the cold insulation agent 5 from the in-wall accommodation portion 11. Is desirable. Further, the right support wall portion 14 is provided in the center portion in the vertical direction of the cold insulation agent 5 accommodated in the in-wall accommodation portion 11 in order to further enhance the effect of improving the ease of taking out the cold insulation agent 5. It is desirable that it be formed lower than that. Further, by configuring the right support wall portion 14 to be as low as possible, there is an effect that heat exchange between the in-wall housing portion 11 and the housing space 3 can be more positively performed.

  (B) In the above embodiment, the left support wall 13 and the right support wall 14 are separated from each other, but the left support wall 13 and the right support wall may be connected (directly connected). May be) In this case, there is a region in a range that can come into contact with the left side portion of the cooling agent 5 accommodated in the in-wall accommodating portion 11 (when the corner portion is chamfered, the chamfered surface is also included in the left side portion). It constitutes the left support wall part and abuts on the right side part of the cooling agent 5 accommodated in the in-wall accommodating part 11 (when the corner part is chamfered, the chamfered surface is also included in the right side part). The part of the range to obtain comprises a right support wall part. However, in the case where the cold-retaining agent 5 performs heat exchange with the accommodation space 3 of the box-type container 1, and consequently with the accommodations accommodated in the accommodation space 3, the area communicating with the accommodation space 3 is reduced. Since it is desirable to make it as large as possible, it is desirable that the left support wall 13 and the right support wall 14 are separated from each other in the left and right directions. In addition, the cleanability of the in-wall housing portion 11 can be improved by separating the left support wall portion 13 and the right support wall portion 14 from each other.

  (C) In the above embodiment, the cold insulation agent 5 is employed as the specific article, but it may be for maintaining the other accommodation space 3 so as to be a suitable environment for the contained item, for example, Insulating agents, desiccants, moisturizing agents, deodorizing agents, fragrances, insect repellents, preservatives and the like can be mentioned. In addition, the specific article does not necessarily need to maintain the accommodation space 3 so as to be a suitable environment for the contained item. For example, the specific article is an accessory (main body) that is contained in the accommodation space 3 ( A substantially flat plate) may be accommodated in the in-wall accommodating portion 11. In addition, the articles accommodated in the accommodation space 3 are not particularly limited, and may include industrial parts having complicated shapes in addition to foods that require temperature management.

  (D) In the said embodiment, although the inclination-angle of the left side control surface 15 with respect to the bottom face of the in-wall accommodating part 11 is 89 degree | times, it is substantially the same as the perpendicular direction with respect to the side surface of the in-wall accommodating part 11, or it is close to it. It is sufficient that the angle is more specifically about 80 to 90 degrees. Moreover, in the said embodiment, although the inclination angle of the right side control surface 16 with respect to the bottom face of the in-wall accommodating part 11 is 70 degree | times, it should just be comprised loosely rather than the left side control surface 15. FIG. However, the inclination angle of the right-side regulating surface 16 which is a gentler inclination is that the region where the cold-retaining agent 5 comes into contact with the left-side regulating surface 15 in the inner-wall housing portion 11 when the cold-retaining agent 5 is taken out from the inner-wall housing portion 11. It is desirable that the rotation is set based on the rotation radius of the coolant 5 (for example, about 60 to 75 degrees) so that it can rotate around (upper left corner).

  (E) In the above embodiment, the left support wall 13 is configured to be higher than the right support wall 14, but the right support wall 14 is configured to be higher than the left support wall 13. May be. Further, in the above embodiment, the left regulating surface 15 has a steeper angle than the right regulating surface 16, but the right regulating surface 16 has a steeper angle than the left regulating surface 15. You may comprise so that it may become an angle.

  Furthermore, in the said embodiment, corresponding to the left-right one side part side (left side part side) of the in-wall accommodating part 11, the taller one (high wall part) of the left support wall part 13 and the right support wall part 14 And the left regulating surface 15 and the right regulating surface 16 having a steep inclination angle (steep slope) and corresponding to the left and right other side (right side) of the in-wall housing portion 11. Of the wall portion 13 and the right support wall portion 14, the shorter one (low wall portion) and the one of the left restriction surface 15 and the right restriction surface 16 having a gentle inclination angle (slow slope) are provided. The high wall portion and the gentle slope may be provided on the same side of the left and right, and the low wall portion and the steep slope may be provided on the same side of the left and right. However, in the case of adopting this configuration, when the cold insulation agent 5 is taken out from the in-wall housing portion 11, if the cold insulation agent 5 is lifted in a substantially vertical direction, the cold insulation agent 5 and the steep slope are in sliding contact, and it is difficult to lift the cold insulation agent. Since there is a concern that the agent 5 and the steep slope may be damaged and dirt or the like may be easily attached, it is desirable to provide the low wall portion and the gentle slope on the same left and right sides as in the above embodiment. .

  (F) In the above embodiment, as a method of taking out the cold insulation agent 5 from the in-wall housing portion 11, the upper right portion of the cold insulation agent 5 exposed to the inside of the container above the right support wall portion 14 is picked, and the substantially vertical direction is obtained. Although lifting is disclosed, it is a matter of course that the removal method is not a single method but is left to the operator. For example, as shown in FIG. 9, the left upper portion of the cold insulating agent 5 is turned to the left in the inner wall accommodating portion 11 so as to be once along the right side regulation surface 16, thereby causing the upper left portion of the cold insulating agent 5 to move to the inner wall accommodating portion. 11. As a result, after making it protrude upward from the container main body 2, it is also possible to take out the cold insulating agent 5 by picking up the upper left part of the said cold insulating agent 5. FIG.

  (G) In the above embodiment, the upper end position of the left support wall 13 and the upper end position of the left restricting surface 15 are the same height, and the upper end position of the right support wall 14 and the right restricting surface 16 are the same. The upper end position of the left support wall 13 is not particularly limited to such a configuration. For example, as shown in FIGS. It may be formed up to a position higher than the portion.

  Moreover, in the said embodiment, although the inner side accommodating part 11 is formed so that the inner surface of the long side wall part 8 may be expanded outside a container, the inner surface (general surface) of the long side wall part 8 is formed. It is good also as forming the storage part 11 in a wall so that it may protrude inward from a container. However, in this case, since the accommodation space 3 is narrowed and the shape of the accommodation space 3 is distorted, the wall is formed so that the inner surface of the long side wall portion 8 is expanded outward as in the above embodiment. It is desirable to form the inner housing part 11.

  (H) In the above-described embodiment, the box-shaped container 1 is provided with the lid member 4 that is detachable from the container body 2, but the lid member is rotatably connected to the container body 2. The present invention may be applied to a box-shaped container having 4 or a box-shaped container having no lid member 4. Moreover, it is also possible to apply to a foldable box-type container. Furthermore, it is also possible to apply to a box-shaped container configured by assembling a plurality of box-shaped bodies in a nested manner (the in-wall housing portion 11 and the like are formed in an inner box-shaped body).

  Furthermore, in the said embodiment, although the in-wall accommodating part 11 is formed in one long side side wall part 8, the side wall parts 8 and 9 used as the object of formation of the in-wall accommodating part 11, and in-wall accommodation The number of the parts 11 is not particularly limited, and is appropriately designed according to the articles to be accommodated. For example, the in-wall housing portion 11 may be formed on each of the pair of long side wall portions 8. In addition, in the said embodiment, although the bottom face of the storage space 3 of the container main body 2 and the bottom face of the storage part 11 in a wall are the same, you may be level | step difference in the up-down direction.

  (I) In the above embodiment, the box-shaped container 1 is made of a foam material, but may be made of a non-foam material. Moreover, in the said embodiment, although the box-type container 1 is comprised by the polypropylene, it is good also as comprising by other resin materials, such as polyethylene, a polystyrene, PET, a polyamide.
