The upper lid 20 is configured to close the upper surface opening 10 </ b> A of the container body 10 by fitting the fitting ridge 16 to the outside of the fitting ridge 15 of the container body 10. In addition, a laterally long notch 20K into which a finger can be inserted is formed on the outer surfaces of the front and rear side walls 23, 23 of the upper lid 20 so that the upper lid 20 fitted to the container body 10 can be easily released. ing.

  Further, on the upper portion 21 of the upper lid 20, a pair of outer protrusions 24, 24 projecting along the longitudinal direction on both sides in the width direction of the outer peripheral portion on the upper surface side, and these outer protrusions 24, 24. A pair of inner projecting portions 25 and 25 projecting at both front and rear ends, and projecting from the inner projecting portions 25 and 25 by a predetermined distance away from each other on the radially inner side (center side in the front and rear direction of the upper lid 20). And a pair of spaced apart protruding portions 26, 26, and a flat-fitting groove fitting portion 20A that is recessed radially inward of the outer protruding portions 24, 24 and the inner protruding portions 25, 25. In the first embodiment, a pair of front and rear projections 18A and 18A, which will be described later, are regulated from both sides in the width direction by a pair of outer protrusions 24 and 24 in the width direction and a pair of inner protrusions 25 and 25 in the front and rear. A plurality of width direction convex portions projecting upward so as to be positioned on both sides in the width direction with respect to the pair of front and rear direction convex portions 18A and 18A are configured.

  The outer protrusions 24, 24 are disposed on the outermost side in the width direction among the constituent members of the width direction convex portion. Further, the outer protrusions 24 and 24 are formed so as to extend over the entire front-rear direction of the upper portion 21. The inner protrusions 25 and 25 are formed only in the central region excluding both ends in the width direction of the upper portion 21. That is, the guide recesses 27 formed between the front end portions (or the rear end portions) of the outer protrusion portions 24 and 24 are formed on both sides of the inner protrusion portions 25 and 25 in the width direction. Therefore, the outer protrusions 24 and 24 and the inner protrusions 25 and 25 are not continuous and are interrupted at four places where the guide recesses 27 are present.

  The concave line fitting portion 20 </ b> A is formed in substantially the entire region (region on the inner diameter side) of the upper portion 21 surrounded by the outer protrusions 24 and 24 and the inner protrusions 25 and 25. The concave fitting portion 20A is flush with the bottom surface (lower surface) of the guide recess 27 so as to be continuous with the guide recess 27. That is, the upper surface of the upper portion 21 is a flat surface in a region where the concave line fitting portion 20A and the guide concave portion 27 are combined.

  The separation protrusions 26 and 26 located closer to the center side in the front-rear direction than the inner protrusions 25 and 25 are formed only in the central region excluding both ends in the width direction of the upper portion 21, and the length and position in the width direction are The length and position of the inner protrusions 25, 25 in the width direction are the same. Therefore, the width direction both sides of the separated protrusions 26 and 26 of the flat surface of the concave fitting portion 20A have the same width as that of the guide concave portion 27 (that is, wider than the other portions of the concave fitting portion 20A). Narrow).

  Here, the one front-rear protrusion 18A (the lower front-rear protrusion 18A in FIG. 5A) and the corresponding one of the outer protrusions 24 (the upper outer protrusion in FIG. 5A). The first guide means 29 is constituted by the width direction convex part which consists of the part 24) and the inner side protrusion parts 25 and 25. As shown in FIG. Further, the other front-rear direction protrusion 18A (upper front-rear direction protrusion 18A in FIG. 5A) and one outer protrusion 24 corresponding thereto (the lower outer protrusion in FIG. 5A). 24) and the width direction convex part which consists of the inner side protrusion parts 25 and 25, the 2nd guide means 30 is comprised. The first and second guide means 29 and 30 are two guide means provided side by side in the width direction, and in order to stack the plurality of cold storage containers 1 and 1 up and down in an uneven fitting state, the lower cold storage container 1 When the upper cold storage container 1 is slid in the front-rear direction, the upper cold storage container 1 is guided along the front-rear direction (longitudinal direction). Here, the inner projecting portions of the two guiding means 29 and 30 are also used as the inner projecting portions 25 and 25. However, the inner projecting portions 25 and 25 are divided into two in the width direction, The inner projecting portions corresponding to the two guide means 29 and 30 can also be used.

  In the cold storage container 1 having such a configuration, when a plurality of stacks are stacked on the loading platform of a truck to be transported by land, or when a plurality of stacks are stacked on an air container for air transportation, that is, when a stacking operation is performed, a pair of front and rear projections 18A, One of the front protrusions 18A (the lower front protrusion in FIG. 5A) 18A is one outer protrusion 24 of the upper lid 20 (the outer protrusion on the upper side in FIG. 5A). The guide recess 27 is formed by the inner side surface 24a of the inner projecting portion 25a and the widthwise one end surfaces 25a, 25a of the inner projecting portions 25, 25 opposed to the inner side surface 24a. The other front-rear direction convex part (the upper front-rear direction convex part in FIG. 5A) 18A is the inner side surface of the other outer protrusion part (the upper outer protrusion part in FIG. 5A) 24 of the upper lid 20. The guide recess 27 is formed by 24a and the other widthwise end surfaces 25b, 25b of the inner projecting portions 25, 25 positioned opposite to each other. In this state, the upper cold storage container 1 is guided to move. In the first embodiment, the front-rear direction protrusions 18A of the upper cold storage container 1 are formed on the inner side surface 24a of the outer protrusion 24 of the lower cold storage container 1 and the width direction end face 26a (26b) of the separation protrusion 26. ) Also enters the narrow part between and is guided to move. That is, the separation protrusion 26 also serves as a guide function.

  And just before the connection convex part 18B of the upper cold storage container 1 comes into contact with or comes into contact with the inner protrusion 25 located at the rear end (front side of the cold storage container), the rear end part of the upper cold storage container 1 is lifted and connected. The upper cold storage container 1 is moved so that the convex portion 18B gets over the inner protruding portion 25.

  And as shown in FIG.5 (b), the connection convex part 18B fits between the inner side protrusion part 25 and the space | interval protrusion part 26 located ahead rather than this, and with respect to the cold storage container 1 of the lower side. The upper cold storage container 1 can be stacked while being positioned.

  In this way, since the upper cold storage container 1 is guided by the two guide means 29 and 30 so that the upper cold storage container 1 is moved, the upper cold storage container 1 is reliably guided and slid without being displaced. Are stacked on the cold storage container 1.

  As shown in FIGS. 5C and 5D, in a state where the upper cold storage container 1 is stacked on the lower cold storage container 1, the lower surface (bottom surface) of the convex portion 18 and the upper surface of the upper lid 20. There is no contact with 20S. Therefore, when the upper cold storage container 1 is moved, the pair of outer protrusions 24, 24 of the upper lid 20 and the corresponding widthwise side portions 17A, 17A of the outer peripheral recess 17 at the bottom of the container body 10 come into contact with each other. The part of is not in contact.

  When the stacked upper cold storage container 1 is unloaded from the lower cold storage container 1 (that is, when unloading is performed), the rear holding portions 31B and 31B of the upper cold storage container 1 and a pair of handles 32 are used. , 32, the rear end portion of the upper cold storage container 1 is lifted upward, and the connecting projection 18B is detached from between the inner projection 25 and the separation projection 26. Thereafter, by putting the hands in the handles 32 and 32 and pulling the upper cold container 1 to the front side (rear side in the front-rear direction), the upper cold container 1 can be easily lowered. In addition, by providing a pair of front and rear spaced projections 26, 26, it is possible not only to have a front-rear direction of the upper lid 20 with respect to the container body 10, but also to set the front end portion of the upper cold storage container 1 to the front side. Can be supported by the separated protrusions 26. Note that the separating protrusion 26 can be provided only on the front side (rear end side).

  Moreover, there exists the following advantage by comprising the convex part 18 in the U shape where the front end was open | released. That is, when the convex portion 18 is configured in an annular shape having a connecting convex portion (not shown) on the front side, the front connecting convex portion is disposed between the two front protrusions 25 and 26 in a stacked state. When the upper cold storage container 1 is pulled out, it is necessary to lift the upper cold storage container 1 greatly so as to release the fitting of the front connecting projections fitted between the protrusions 25 and 26. There is. On the other hand, in the U-shaped convex portion 18, the connecting convex portion 18 </ b> B fitted between the protruding portions 25 and 26 on the rear side (the front side in the direction of moving the cold container) is slightly higher to release the fitting. It is only necessary to lift the cold storage container 1 and the cold storage container 1 can be pulled out easily.

  In addition, if a friction coefficient reducing tape or the like is attached to at least one of the contact portions between the upper cold storage container 1 and the lower cold storage container 1, the frictional resistance is reduced, and the sliding of the cold storage container 1 is reduced. The dynamic operation force can be kept small. The tape may be an OPP (biaxially stretched polypropylene) tape, or may be various synthetic resin tapes.

  When stacking the upper cold storage container 1 while sliding it on the lower cold storage container 1, as shown in FIGS. 5 (a) and 5 (c), the pair of outer protrusions 24, 24 of the upper lid 20 and this The left and right side portions 17A, 17A of the outer peripheral edge of the bottom of the container body 10 corresponding to the area are in contact with each other, and the bottom surface of the upper cold storage container 1 and the upper surface of the upper cover 20 of the lower cold storage container 1 are in sliding contact with each other. Can be reduced. From this, it is possible to suppress an artificial operation force for sliding the upper cold storage container 1 relative to the lower cold storage container 1, and there is an advantage that the upper cold storage container 1 can be easily moved. In addition, since the gap between the outer protrusions 24, 24 and the inner protrusions 25, 25 is a guide recess 27, the upper cold container 1 is parallel to the lower cold container 1. It can be moved in a horizontal position.

<Second embodiment>
Next, a second embodiment in which the convex portion 18 provided on the bottom surface of the container body 10 shown in FIG. 5A is configured as shown in FIGS. 6A and 6B will be described. The right side container body 10 in FIG. 6A is shown in a bottom view, and when stacked on the upper lid 20 of the left side cold storage container 1, the container body 10 is set upside down.

  The cold insulation container 1 according to the second embodiment does not include the connecting convex portions in the first embodiment, that is, the pair of front and rear direction convex portions 18A and 18A are not connected to each other and are parallel to each other with a predetermined interval. It is configured. Further, the groove fitting portion 20A is formed so that the inner diameter portion is concave rather than the rectangular outer circumferential convex portion formed by the four outer sides 20B, 20C, 20D, and 20E of the upper lid 20, and the groove fitting is performed. When the pair of front and rear direction convex portions 18A and 18A are fitted (internally fitted) to the portion 20A, the upper and lower cold insulation containers 1 in the stacked state are positioned. In addition, inner protrusions 41, 42, 43 that protrude upward and extend in the width direction are formed at three positions in the front-rear direction (front end part, center part, rear end part) in the concave line fitting part 20 </ b> A of the upper lid 20. Yes.

  In the second embodiment, one of the above-mentioned ones (the upper side of the container body 10 in FIG. 6A) is the front-rear direction convex part 18A (the upper front-rear direction convex part 18A in FIG. 6A) and the corresponding upper lid.
