FIG. 14 is a perspective view showing a state in the heat insulating container in a state where the heat storage material and the ventilation plate are placed in the box portion of the heat insulating container of the embodiment and the shelf member is folded and stored.

  In the box 10, a plurality of heat storage plates (heat storage materials) 12, 15, one ventilation plate 77, and two shelf members 78 are installed. Since the heat storage plate (heat storage material) 12 stores cold energy, and the heat storage plate (heat storage material) 15 stores heat, both are selectively used.

  The heat storage plate (heat storage material) 15 stores high temperature, and is heated to a desired temperature by being heated in a microwave oven, and stores heat energy. The heat storage plate (heat storage material) 12 is cooled in a refrigerator to store the cold energy. Each of the heat storage plates 12 and 15 has a plate shape or a block shape, and has a short rectangular parallelepiped shape.

  The ventilation plate (plate body) 77 is a resin or metal plate having a certain degree of rigidity, and a large number of holes 79 are opened. The ventilation plate 77 is rectangular, and the area and shape thereof are slightly smaller than the shape and area of the inner bottom surface of the box body 10. The ventilation plate 77 has a function of preventing a hamburger or the like from directly touching the heat storage plate (heat storage material) 15.

  The shelf member 78 is obtained by punching a single resin plate and bending it, and includes a top plate (top plate portion) 81 having a large number of holes 80 and two leg plates (leg portions) 82. Is. The top plate 81 has a substantially square shape, and the area and shape thereof occupy half of the inner bottom surface of the box body 10.

  The leg plate 82 is provided on opposite sides of the top plate 81, and a crease 87 is provided between the leg plate 82 and the top plate 81.

  The width of the leg plate 82 is equal to that of the top plate 81. When the leg plate 82 is bent at 90 degrees with respect to the top plate 81, the entire shelf member 78 becomes a trapezoid as shown in FIG. As described above, the area and shape of the top plate is the shape and area that occupies half of the inner bottom surface of the box body 10, and the leg plate 82 is provided on the opposite side of the top plate 81. The outer dimension is substantially equal to the inner width of the box body part 10.

  A number of ventilation holes 80 are provided in the top plate 81. Further, a short edge piece (bending portion) 83 is provided in the entire area of the other two opposite sides of the top plate 81. In the present embodiment, the width of the edge piece 83 is equal at any position. Further, the edge piece 83 is provided with thick portions 95 at both ends in the longitudinal direction.

  There is also a folding device 88 between the edge piece 83 and the top plate 81, and the edge piece 83 is bent so as to be inclined with respect to the top plate 81 when the shelf member 78 is used, thereby reinforcing the top plate 81. Therefore, the top plate 81 has high rigidity against bending, and an object can be placed on the top plate 81.

  Further, when the leg plate 82 is folded in parallel with the top plate 81, the shelf member 78 becomes low in volume as shown in FIG.

  Next, the usage method of the heat insulation container 1 of this Embodiment is demonstrated.

  The insulated container 1 of the present invention can be applied to a container that should be transported while maintaining a temperature higher than room temperature, such as a hamburger, or a container that should be transported while maintaining a temperature lower than room temperature, such as ice cream. .

  When carrying an object while maintaining a temperature higher than normal temperature like a hamburger, a high-temperature heat storage plate 15 is installed at the bottom of the box 10. A ventilation plate 77 is placed on the heat storage plate 15, and an article to be kept warm, such as a hamburger 86, is placed thereon.

  Since a large number of holes 79 are provided in the ventilation plate 77, the heat of the heat storage plate 15 reaches the upper part through the holes 79 and convects inside the heat insulating container 1. Moreover, since the heat insulation container 1 is covered with the vacuum heat insulating material 30 as described above, the heat in the storage is difficult to escape to the outside, and the hamburger and the like are kept at a predetermined temperature.

  Further, when storing more hamburgers 86 and the like, a shelf member 78 is installed in the box body portion 10 so that the hamburgers 86 and the like are not crushed.

  That is, as shown in FIG. 13, the leg plate 82 is bent at 90 degrees with respect to the top plate 81 and installed in the box portion 10. As shown in FIG. 13, it is desirable to install two shelf members 78 side by side.

  The area and shape of the top plate 81 is a shape and area that occupies half of the inner bottom surface of the box body 10, and the outer dimensions of the leg plates 82 are substantially equal to the inner width of the box body portion 10, so the shelf member 78. The leg plate 82 is erected along the inner wall of the box 10.

  If attention is paid to the lower part of the leg plate 82, as shown in FIG. 13, there is a ventilation plate 77 between the leg plates 82. That is, since the ventilation plate 77 is placed on the heat storage plate 15, the ventilation plate 77 is at a position slightly away from the bottom of the box body portion 10. Further, since the ventilation plate 77 is smaller than the area of the box body portion 10, there is a gap 90 between the ventilation plate 77 and each inner wall 91 of the box body portion 10.

  Therefore, the leg plate 82 is fitted into the gap 90 between the ventilation plate 77 and the box body portion 10. As a result, the lower part of the leg plate 82 is regulated by both, and the leg plate 82 does not move inward. Moreover, since the upper part side of the leg part 82 is connected with the top plate 81, the distance of the upper part side of the leg part 82 does not change. Furthermore, an inner wall 91 of the box body 10 is provided on the back side (outside) of the leg portion 82. Therefore, the quadrangle formed by the top plate 81, the leg portion 82, and the ventilation plate 77 is a rectangle or a square and is not crushed into a rhombus.

  Further, as described above, the top plate 81 of the shelf member 78 has a shape and an area that occupies half of the inner bottom surface of the box body portion 10, so that when the two shelf members 78 are installed side by side, the two top plates 81 are formed. It will occupy the entire area of the box 10. That is, by arranging two shelf members 78, the shelf members 78 are spread in the box body portion 10, and substantially the entire plane area of the box rod 10 is covered.

  For this reason, the edge pieces 83 provided on the two sides of the top plate 81 are in contact with the adjacent edge pieces 83 or the inner wall of the box body portion 10, and become a right angle posture with respect to the top plate 81, and this posture is maintained. In particular, in the present embodiment, thick portions 95 are provided at both ends of the edge piece 83, and the thick portion 95 of one shelf member 78 and the thick portion 95 of the other shelf member 78 are overlapped. A portion is sandwiched between each leg plate 82.

  Since the width of the leg plate 82 is equal to the width of the top plate 81, when the two shelf members 78 are laid in the box body portion 10, the leg plate 82 comes into contact with the adjacent leg plate 82 and the movement in the longitudinal direction is also restricted. It will be in a state to be. Therefore, the thick portion 95 of the edge piece 83 is strongly pressed by the leg plate 82 and maintains a right-angled posture with respect to the top plate 81.

  As a result, the section modulus of the top plate 81 is increased, the top plate 81 is reinforced, and the strength against bending is improved. Therefore, the top plate 81 is difficult to bend even if a heavy object is placed on the top plate 81.

  Therefore, a hamburger or a drink can be placed on the top plate 81. Further, the hamburger placed under the shelf member 78 is not crushed.

  In the present embodiment, since the top plate 81 is provided with the vent holes 80, the lower hot air passes through the vent holes 80 and convects to the upper portion of the top plate 81 to keep the hamburgers and the like warm.

  When the shelf member 78 is not used, the leg plate 82 is folded as shown in FIG. 12 (b), and is leaned against the inner wall of the box body 10 as shown in FIG. As described above, since the area and shape of the top plate 81 occupy half of the inner bottom surface of the box body portion 10, even when the leg plate 82 is folded, it occupies half of the inner bottom surface of the box body portion 10. Shape and area. Therefore, as shown in FIG. 14, the shelf member 78 can be placed side by side on the inner wall on the long side. Of course, it may be placed one by one on the inner wall on the short side, or two may be placed on the inner wall on the short side.

  For those that need to be transported in a cooled state, such as ice cream, the regenerator material is stored in the regenerator attachment parts 56, 57 provided on the lower surface of the lid 8, and the ice cream or the like is placed in the box 10. Store. Of course, the regenerator material may be housed in the bottom of the box body portion 10, and the ventilation plate 77 may be placed thereon or the shelf member 78 may be erected.

  Conversely, when the temperature is kept at a high temperature as described above, a high-temperature heat storage plate may be accommodated in the heat storage material mounting portions 56 and 57.

  And the cover part 8 of the box part 10 is closed, the flaps 51, 52, 53 provided on the cover part 8 are hung outside the main body side, and the surface fastener provided on the flaps 51, 52, 53 is attached to the outer box member. 16 is engaged with a hook-and-loop fastener 50 provided in the vicinity of the opening end. As a result, the lid portion 8 of the box body portion 10 is closed, and internal hot air and cold air cannot leak.

  Then, the insulated container 1 is carried to a desired place. In the heat insulating container 1 of the present embodiment, since the shoulder belt (strap string) 11 is provided, the heat insulating container 1 is transported with the shoulder belt (strap string) 11 on the shoulder as shown in FIG. FIG. 15 is an explanatory diagram illustrating a state when the heat insulating container illustrated in FIG. 1 is transported.

  Here, in the heat insulating container 1 of the present embodiment, the belt interval of the attachment portion (fixed string portion 68) of the shoulder belt (strap string) 11 with respect to the box body portion 10 gradually narrows from the lower side toward the upper side. The inclination angle of the fixed string portion 68 is such that the intermediate portion of the box attachment portion 60 is lifted onto the central axis of the peripheral wall portion 43 on the same plane as the peripheral wall portion 43, and the free portion 69 of the box attachment portion 60. When the slack is eliminated, the angle between the center 74 of the free portion 69 of the box attachment portion 60 and the end of the one end side box attachment portion 60 is a straight line.

  Therefore, when the user hangs the portion of the connecting member 62 of the shoulder belt 11 on the shoulder, from the lower end of the shoulder belt 11, that is, from the lower corner of the peripheral wall portion 3 of the box portion 10, The state of the shoulder belt (strap string) 11 up to the attachment portion side connecting portions 65 and 66 is substantially linear, and no extreme bending occurs. Therefore, there are few inconveniences, such as pushing the heat insulation container 1 or rubbing a string.

  Therefore, even if it is used for a long period of time, there is little damage to the heat insulation container 1 and the shoulder belt (strap string) 11.

  In addition, although the heat insulation container 1 of this Embodiment is a box shape at the time of use as shown in FIG. 1, it can be folded compactly when not in use.

  That is, in the box part 10, the combination side wall member 18 is folded as shown in FIG. That is, the first inner wall member 22 is bent so that the bottom wall member 26 is in contact, and the second inner wall member 23 and the third inner wall member 25 are folded on the bottom wall member 26.

  And the independent side wall member 20 is drawn near to the combined side wall member 18 side. The outer outer box member 16 is made of a soft resin sheet and can be folded into an arbitrary shape. Therefore, the sheet loosened by moving the independent side wall member 20 is combined with the independent side wall member 20. It can be sandwiched between the side wall members 18.

  Also, the intermediate belt portion 67 of the shoulder belt 11 is removed before and after this.

  A male locking piece 73 is attached to one end of the intermediate belt portion 67 and a male locking piece 75 is attached to the other end, and these are the male locking piece of the intermediate belt portion 67. Since the intermediate belt portion 67 is attached by engaging 73 with the female locking piece 70 of the attachment portion side connecting portion 65, the intermediate belt portion 67 can be removed by releasing these engagements. . Then, the intermediate belt portion 67 that has been removed is wound around the folded heat insulating container 1 and the engagement pieces 73 and 75 at both ends are engaged, whereby the folding of the heat insulating container 1 is completed.

  In the above-described embodiment, the vacuum heat insulating material is adopted as the heat insulating material, but other heat insulating materials may be used.

  In the embodiment described above, the bent portion provided on the top plate portion has a band shape and a constant width, but for example, if the width of the intermediate portion is increased, higher rigidity can be obtained.
