Description

保冷箱Cold box

本發明關於將物品收容而保冷之保冷箱，特別關於可折疊之保冷箱。The present invention relates to a cold storage box for accommodating articles and keeping them cold, and more particularly to a collapsible cold storage box.

物流系統之中，無論陸運、空運，皆提供以固定溫度，例如以低溫輸送物品之服務。以低溫輸送物品之情形下，舉例而言，可將物品與保冷材料一併收納在具有絕熱性之保冷箱，且一邊藉由此保冷材料的冷氣將物品保冷、並一邊輸送。又，於將物品低溫保管在倉庫內之情形亦同樣，可將物品與保冷材料一併收納在具有絕熱性之保冷箱，且一邊藉由保冷材料的冷氣將物品保冷、並一邊保管。Among the logistics systems, both land and air transport provide services at fixed temperatures, such as at low temperatures. In the case of conveying the article at a low temperature, for example, the article and the cold-preserving material may be housed together in a heat-insulating cold storage box, and the article may be cooled while being cooled by the cold air of the cold-preserving material. Further, in the case where the article is stored at a low temperature in a warehouse, the article and the cold-preserving material can be housed together in a heat-insulating cold storage box, and the article can be kept cold while being cooled by the cold air of the cold-preserving material.

就如此保冷箱而言，吾人考慮在外箱內配置成使板狀絕熱材疊合在外箱的內壁（例如參照專利文獻1）。如上所述，使用在外箱即收納容器內配置板狀絕熱板之構成之保冷箱，藉以能不使用具有絕熱性的箱體，而將物品加以保冷。 ［先前技術文獻］ 〔專利文獻〕In the case of the cold box, it is considered that the outer casing is arranged such that the plate-shaped heat insulating material is superposed on the inner wall of the outer casing (see, for example, Patent Document 1). As described above, the cold-insulation box in which the plate-shaped heat insulating plates are disposed in the outer container, that is, the storage container, can be used, so that the articles can be kept cold without using the heat-insulating case.

〔發明所欲解決之問題〕 近年，如同上述，常使用保冷箱而以低溫輸送物品。因此，以低溫輸送物品之情形下，亦尋求接近於以常溫輸送物品之情形之易處理性。就其一例而言，保冷箱與以常溫輸送物品之際所利用的容納器具同樣地需要迅速輕易地折疊又組裝。[Problems to be Solved by the Invention] In recent years, as described above, the cold storage box is often used to transport articles at a low temperature. Therefore, in the case of conveying an article at a low temperature, it is also sought to be close to the ease of handling in the case of conveying the article at a normal temperature. As an example, the cold storage box needs to be quickly and easily folded and assembled in the same manner as the storage device used for conveying articles at normal temperature.

然而，如同上述，於將「在收納容器內配置板狀絕熱材」之保冷箱加以折疊之情形下，舉例而言，係從收納容器取出絕熱材而折疊收納容器。因此，無法迅速輕易地折疊又組裝。於是，吾人考慮由具可撓性之薄片構成收納容器，並於收納容器內配置有板狀絕熱材之狀態下折疊收納容器。然而，此情形下，因為收納容器具可撓性，所以折疊之際無法俐落折疊而容易褶皺，於折疊又組裝之際會花費勞力，難謂能迅速輕易地折疊又組裝。又，於收納容器具可撓性之情形下，會不易將收納容器內所配置之板狀絕熱材加以組裝，亦因此，難謂能迅速輕易地折疊又組裝。However, as described above, in the case where the cold storage box in which the plate-shaped heat insulating material is disposed in the storage container is folded, for example, the heat insulating material is taken out from the storage container to fold the storage container. Therefore, it cannot be folded and assembled quickly and easily. Then, it is considered that the storage container is constituted by a flexible sheet, and the storage container is folded in a state in which the plate-shaped heat insulating material is disposed in the storage container. However, in this case, since the storage container is flexible, it is not easy to fold and fold at the time of folding, and it is easy to wrinkle, and it is laborious to fold and assemble, and it is difficult to fold and assemble quickly and easily. Moreover, when the storage container is flexible, it is difficult to assemble the plate-shaped heat insulating material disposed in the storage container, and therefore it is difficult to fold and assemble quickly and easily.

本發明係鑒於上述以往技術具有之問題點而成，其目的為提供一種保冷箱，能在收納容器內配置有絕熱板之構成之下，迅速輕易地折疊又組裝。 〔解決問題之方式〕The present invention has been made in view of the problems of the prior art described above, and an object thereof is to provide a cold-insulation box which can be quickly and easily folded and assembled under a configuration in which a heat insulating plate is disposed in a storage container. [The way to solve the problem]

為了達成上述目的之本發明，具有：長方體或立方體的收納容器，頂面構成為自由開閉，且至少側面係由可撓性構件構成；以及四個絕熱板，配置為分別疊合疊加在前述收納容器的四個側面的內側，且構成為能以前述收納容器的底面側的端邊為中心，而從疊合在前述側面的內側之狀態自由轉動至朝向於前述底面之狀態。前述四個側面中之彼此相向的一組側面分別具備：由二個略等腰梯形構成之區域，以沿著前述側面的上下的端邊之區域分別作為第一邊，在該第一邊之間共有第二邊，前述第一邊長於前述第二邊。且該區域構成為：較該區域的外側中之「前述二個略等腰梯形的腰」與「該側面和另一側面的連接邊」所圍繞之區域更硬，且在前述第二邊可折疊。In order to achieve the above object, the present invention has a rectangular parallelepiped or a cubic storage container, the top surface of which is configured to be freely opened and closed, and at least the side surface is formed of a flexible member, and four heat insulating plates which are arranged to be superposed and superimposed on the storage. The inner side of the four side faces of the container is configured to be rotatable from the state of the inner side of the side surface to the state of the bottom surface, centering on the end side of the bottom surface side of the storage container. Each of the four side faces facing each other has a region consisting of two slightly isosceles trapezoids, and the first and second sides of the side faces are respectively formed as a first side, and the first side is There is a second side, and the first side is longer than the second side. And the area is configured to be harder than the area surrounded by the "two waists of the first isosceles trapezoid" and the "connecting side of the side and the other side" in the outer side of the area, and the second side can be fold.

如同上述，本發明之中，收納容器的四個側面中彼此相向之一組側面，分別構成為：由「以沿著其側面的上下的端邊之區分別域作為第一邊、在第一邊之間共有第二邊、第一邊長於第二邊長」之二個略等腰梯形構成之區域，較該區域的外側中之「二個略等腰梯形的腰」與「該側面和另一側面的連接邊」所圍繞之區域更硬，且在第二邊可折疊。因此，當使四個絕熱板分別從疊合在由可撓性構件構成之收納容器的側面之狀態轉動至朝向於底面之狀態後，當將收納容器的上端部往下方推壓時，則收納容器的四個側面中之彼此相向之一組側面之中，由二個略等腰梯形構成之區域以形成第二邊的部分成為頂點而向收納容器的內側突出之方式折疊，並一併沿著由二個略等腰梯形構成之區域的外形而折疊；且「二個略等腰梯形的腰」與「其側面和其它側面的連接邊」所圍繞之區域係夾在由略等腰梯形構成的二個區域之方式折疊。而且，如上所述折疊一組側面，藉以於其它側面，以與此一組側面之連接部分的附近係夾在由略等腰梯形構成之二個區域之方式在高度方向中央部分折疊。藉此，將收納容器不褶皺而折疊成規定之形狀，保冷箱被俐落折疊。又，此際，因由二個略等腰梯形構成之區域硬，而收納容器的側面易成為略伸張狀態，藉此，易使絕熱板轉動。又，如上所述，於將已折疊之保冷箱加以組裝之情形下，將收納容器的上端部往上方拉提而伸展側面後，使四個絕熱板分別從朝向於底面之狀態轉動至疊合在側面之狀態。As described above, in the present invention, one of the four side faces of the storage container facing each other is configured such that "the area along the upper and lower end sides along the side faces thereof is respectively the first side, at the first The second side, the first side is longer than the second side, and the two sides are slightly isosceles trapezoidal, and the two sides of the outer side of the area are "two slightly isosceles trapezoidal waist" and "the side and The area around which the connecting side of the other side is surrounded is harder and foldable on the second side. Therefore, when the four heat insulating plates are respectively rotated from the state of being stacked on the side surface of the storage container made of the flexible member to the state facing the bottom surface, when the upper end portion of the storage container is pushed downward, the storage is carried out. Among the four side faces of the four sides of the container, the area formed by the two isosceles trapezoids is folded so that the portion forming the second side becomes the apex and protrudes toward the inner side of the storage container, and is folded along Folded by the shape of the area consisting of two slightly isosceles trapezoids; and the area surrounded by the "two waists of the isosceles trapezoid" and the "connecting sides of the sides and other sides" are sandwiched by a slightly isosceles trapezoid The two areas that make up the fold. Further, a plurality of side faces are folded as described above, whereby the other side faces are folded in the central portion in the height direction so as to be sandwiched by the vicinity of the connecting portion of the one set of the side faces in two regions constituted by the slightly isosceles trapezoidal shape. Thereby, the storage container is folded into a predetermined shape without wrinkles, and the cold storage box is collapsed and folded. Further, in this case, since the region composed of the two slightly isosceles trapezoids is hard, the side surface of the storage container is likely to be slightly stretched, whereby the heat insulating plate is easily rotated. Further, as described above, in the case where the folded cold box is assembled, the upper end portion of the storage container is pulled upward to extend the side surface, and then the four heat insulating plates are respectively rotated from the state toward the bottom surface to the overlap. In the state of the side.

如上所述，只要使四個絕熱板轉動，並一併將收納容器的上端部往下方推壓，則收納容器不褶皺而折疊成規定之形狀，並且因由二個略等腰梯形構成之區域硬，而收納容器的側面易成為略伸張狀態。藉此，能迅速輕易地折疊又組裝保冷箱。 〔發明之效果〕As described above, as long as the four heat insulating plates are rotated and the upper end portion of the storage container is pushed downward, the storage container is folded into a predetermined shape without wrinkles, and the area composed of two slightly isosceles trapezoids is hard. The side of the storage container is likely to be slightly stretched. Thereby, the cold storage box can be folded and assembled quickly and easily. [Effects of the Invention]

本發明之中，收納容器的四個側面中之彼此相向之一組側面分別構成為：由「以其側面的上下的端邊分別作為第一邊、在第一邊之間共有第二邊、第一邊長於第二邊」之二個略等腰梯形構成之區域，較該區域的外側中之「二個略等腰梯形的腰」與「該側面和另一側面的連接邊」所圍繞之區域更硬，且在第二邊可折疊。因此，使四個絕熱板從疊合在收納容器的側面之狀態分別轉動至朝向於底面之狀態後，將收納容器的上端部往下方推壓，則收納容器不褶皺而折疊成規定之形狀。又，將收納容器的上端部往上方拉提而伸展側面後，使四個絕熱板從朝向於底面之狀態分別轉動至疊合在側面之狀態，藉以組裝保冷箱。如上所述，於收納容器內配置有絕熱板之構成下，能迅速輕易地折疊又組裝。又，因由二個略等腰梯形構成之區域硬，而於組裝保冷箱之際收納容器的側面易成為略伸張狀態。藉此，能使絕熱板易轉動，且迅速輕易地組裝保冷箱。In the present invention, one of the four side faces of the storage container facing each other is configured such that "the upper and lower end sides of the side faces respectively serve as the first side, and the first side has the second side, The area where the first side is longer than the second side and the two isosceles trapezoidal is surrounded by the "two slightly isosceles trapezoidal waist" and the "connecting side of the side and the other side" in the outer side of the area. The area is harder and folds on the second side. Therefore, when the four heat insulating sheets are respectively rotated from the state of being superposed on the side surface of the storage container to the state facing the bottom surface, the upper end portion of the storage container is pressed downward, and the storage container is folded into a predetermined shape without wrinkles. Further, after the upper end portion of the storage container is pulled upward and the side surface is extended, the four heat insulating plates are respectively rotated from the state toward the bottom surface to the state of being superposed on the side surface, thereby assembling the cold insulation box. As described above, in the configuration in which the heat insulating plate is disposed in the storage container, it can be quickly and easily folded and assembled. Further, since the area composed of the two slightly isosceles trapezoids is hard, the side surface of the storage container is likely to be slightly stretched when the cold storage box is assembled. Thereby, the heat insulating plate can be easily rotated, and the cold storage box can be assembled quickly and easily.

蓋部11a、11b係具可撓性之二枚鋁薄片疊合而構成。蓋部11a與側面12c的頂面側的端邊連接。又，蓋部11b與側面12c所相向之側面12d的頂面側的端邊連接。而且，蓋部11a、11b以與側面12c、12d之連接邊為中心分別轉動，藉以構成為使收納容器的頂面自由開閉。因此，蓋部11a、11b之中，與側面12c、12d之連接方向的長度，係蓋部11a、11b於封閉之情形下其一部分交疊之長度。The lid portions 11a and 11b are formed by laminating two flexible aluminum sheets. The lid portion 11a is connected to the end side of the top surface side of the side surface 12c. Further, the lid portion 11b is connected to the end side on the top surface side of the side surface 12d facing the side surface 12c. Further, the lid portions 11a and 11b are respectively rotated about the side where they are connected to the side surfaces 12c and 12d, whereby the top surface of the storage container is freely opened and closed. Therefore, among the lid portions 11a and 11b, the length in the direction in which the side faces 12c and 12d are connected is a length in which the lid portions 11a and 11b are partially overlapped in the case of closing.

蓋部11a、11b在成為收納容器的內側的面，分別安裝有彼此具有同一形狀之絕熱板21a、21b。絕熱板21a之中，不朝向於蓋部11a之面整面係以鋁薄片覆蓋。於蓋部11a、11b係封閉之情形下，絕熱板21a以不干涉下者的方式，以從蓋部11a的周緣部退開絕熱板22a、22b的厚度大小的方式安裝至內側的約略整面：疊合在側面12a～12c之絕熱板22a～22c；以及蓋部11b。絕熱板21b之中，不朝向於蓋部11b的面整面係以鋁薄片覆蓋。於蓋部11b係封閉之情形下，絕熱板21b以不干涉疊合在側面12a、12b、12d之絕熱板22a、22b、22d之方式，避開沿著下者的區域而安裝在約略整面：蓋部11b之與側面12d的連接邊；以及前述連接邊所銜接的邊。藉此，蓋部11a、11b與側面12c、12d之連接方向的長度如下：蓋部11a較蓋部11b長「彼此重疊的區域的大小」。The lid portions 11a and 11b are respectively provided with heat insulating plates 21a and 21b having the same shape as each other on the inner surface of the storage container. Among the heat insulating plates 21a, the entire surface of the surface of the lid portion 11a is not covered with an aluminum foil. When the lid portions 11a and 11b are closed, the heat insulating plate 21a is attached to the innermost surface of the heat insulating plates 22a and 22b so as not to interfere with the thickness of the heat insulating plates 22a and 22b from the peripheral edge portion of the lid portion 11a. : heat insulating plates 22a to 22c superposed on the side faces 12a to 12c; and a lid portion 11b.

搖蓋部51a、51b之中，搖蓋部51a、51b係折疊之情形下成為收納容器的內側的面，以沿著與側面12a、12b之連接邊的方式安裝有黏扣帶36。又，搖蓋部51a、51b之中，搖蓋部51a、51b係折疊之情形下成為收納容器的外側的面中之搖蓋部51a、51b的長邊方向中央部，安裝有黏扣帶35。Among the flap portions 51a and 51b, when the flap portions 51a and 51b are folded, the inner surface of the container is formed, and the fastening tape 36 is attached along the side of the side surface 12a and 12b. Further, in the flap portions 51a and 51b, when the flap portions 51a and 51b are folded, the center portion in the longitudinal direction of the flap portions 51a and 51b on the outer surface of the storage container is attached with the fastening tape 35. .

絕熱板22a、22b之中，其整面係以鋁薄片覆蓋，且具有與側面12a、12b的寬度係同等之寬度。絕熱板22a、22b具有以下高度：自側面12a、12b的高度減去將絕熱板23及後述絕熱板22c、22d疊合之厚度。絕熱板22a、22b於絕熱板23的端邊所安裝之非折曲部25上豎起之狀態疊合在側面12a、12b，且與非折曲部25之抵接面中之與疊合的側面12a、12b為相反側的邊，係藉由縫合等而接合至非折曲部25。藉此，絕熱板22a、22b分別構成為：能以底面13側的端邊為中心，而從疊合在側面12a、12b之狀態自由轉動至朝向於底面13之狀態。Among the heat insulating plates 22a and 22b, the entire surface thereof is covered with an aluminum foil and has a width equivalent to that of the side faces 12a and 12b. The heat insulating plates 22a and 22b have a height from the height of the side faces 12a and 12b minus the thickness at which the heat insulating plate 23 and the heat insulating plates 22c and 22d described later are superposed. The heat insulating plates 22a and 22b are erected on the non-folded portions 25 to which the end faces of the heat insulating plates 23 are erected, and are superimposed on the side faces 12a and 12b, and overlapped with the non-curved portions 25. The side faces 12a and 12b are opposite sides, and are joined to the non-curved portion 25 by sewing or the like. Thereby, each of the heat insulating plates 22a and 22b is configured to be able to freely rotate from the state of being overlapped on the side faces 12a and 12b to the state of the bottom face 13 centering on the end side on the bottom face 13 side.

非折曲部25，其高度係與將絕熱板22c、22d疊合之厚度同等。藉此，當將絕熱板22c、22d定為朝向於底面13之狀態後，並再將絕熱板22a、22b定為與底面13相向之狀態時，則如圖2b所示，絕熱板22a、22b的朝上的面成為與底面13約略平行的狀態。此外，具認為非折曲部25係由與絕熱板22a、22b同等的材料構成，但非折曲部25不構成本願發明中之絕熱板。The height of the non-curved portion 25 is equal to the thickness at which the heat insulating plates 22c and 22d are superposed. Thereby, when the heat insulating plates 22c and 22d are set to face the bottom surface 13, and the heat insulating plates 22a and 22b are set to face the bottom surface 13, the heat insulating plates 22a and 22b are as shown in Fig. 2b. The upward facing surface is approximately parallel to the bottom surface 13. Further, it is considered that the non-buckling portion 25 is made of the same material as the heat insulating plates 22a and 22b, but the non-bending portion 25 does not constitute the heat insulating plate in the present invention.

側面12c、12d彼此相向配置，且係具可撓性之二枚鋁薄片疊合而構成。側面12c、12d，以疊合在成為收納容器的內側的面之方式配置有絕熱板22c、22d。The side faces 12c and 12d are disposed to face each other, and are formed by laminating two flexible aluminum sheets. The side surfaces 12c and 12d are provided with heat insulating plates 22c and 22d so as to be superposed on the inner surface of the storage container.

絕熱板22c、22d之中，其整面係以鋁薄片覆蓋，且具有以下寬度：從側面12c、12d的寬度減去絕熱板22a、22b的厚度。絕熱板22c具有以下高度：從側面12c的高度減去絕熱板23的厚度。絕熱板22c以豎起在絕熱板23的端邊之狀態疊合在側面12c，且「與絕熱板23之抵接面中之與側面12c係相反側」的邊，係藉由縫合等而接合至絕熱板23。藉此，絕熱板22c構成為：能以底面13側的端邊中心，而從疊合在側面12c之狀態自由轉動至朝向於底面13之狀態。絕熱板22d具有以下高度：從側面12d的高度減去絕熱板22c及絕熱板23的厚度。絕熱板22d以絕熱板23的端邊所安裝之非折曲部24上豎起之狀態疊合在側面12d，且「與非折曲部24之抵接面中之與側面12d係相反側」的邊，係藉由縫合等而接合至非折曲部24。藉此，絕熱板22d構成為：能以底面13側的端邊中心，而從疊合在側面12d之狀態自由轉動至朝向於底面13之狀態。此外，吾人認為非折曲部24係由與絕熱板22d同等的材料構成，但非折曲部24不構成本願發明中之絕熱板。Among the heat insulating plates 22c and 22d, the entire surface thereof is covered with an aluminum foil and has a width from which the thickness of the heat insulating plates 22a and 22b is subtracted from the width of the side faces 12c and 12d. The heat insulating plate 22c has a height from which the thickness of the heat insulating plate 23 is subtracted from the height of the side surface 12c. The heat insulating plate 22c is superposed on the side surface 12c in a state of being erected on the end side of the heat insulating plate 23, and the side opposite to the side surface 12c of the abutting surface of the heat insulating plate 23 is joined by sewing or the like. To the insulation board 23. Thereby, the heat insulating plate 22c is configured to be freely rotatable from the state of being overlapped on the side surface 12c to the state of facing the bottom surface 13 at the center of the end side on the bottom surface 13 side. The heat insulating plate 22d has a height from which the thickness of the heat insulating plate 22c and the heat insulating plate 23 is subtracted from the height of the side surface 12d. The heat insulating plate 22d is superposed on the side surface 12d with the non-buckling portion 24 attached to the end side of the heat insulating plate 23 erected, and "the side opposite to the side surface 12d of the abutting surface of the non-buckling portion 24" The side is joined to the non-curved portion 24 by sewing or the like. Thereby, the heat insulating plate 22d is configured to be freely rotatable from the state of being overlapped on the side surface 12d to the state facing the bottom surface 13 at the center of the end side on the bottom surface 13 side. Further, it is considered that the non-bending portion 24 is made of the same material as the heat insulating plate 22d, but the non-buckling portion 24 does not constitute the heat insulating plate in the present invention.

絕熱板22c、22d具有當將其分別定為朝向於底面13之狀態時則一部分彼此疊合之高度。因此，非折曲部24的高度成為與絕熱板22c的厚度同等，藉此，當將絕熱板22c定為朝向於底面13之狀態後，並再將絕熱板22d定為與底面13相向之狀態時，則如圖3b所示，絕熱板22d的朝上的面係底面13約略平行的狀態。The heat insulating plates 22c, 22d have a height at which a part overlaps each other when they are respectively set to face the bottom surface 13. Therefore, the height of the non-bending portion 24 is equal to the thickness of the heat insulating plate 22c, and after the heat insulating plate 22c is set to face the bottom surface 13, the heat insulating plate 22d is set to face the bottom surface 13 again. At this time, as shown in Fig. 3b, the upwardly facing surface of the heat insulating plate 22d is in a state in which the bottom surface 13 is approximately parallel.

以下，說明如同上述構成之保冷箱1的使用方法。Hereinafter, a method of using the cold box 1 having the above configuration will be described.

首先，說明保冷箱1的折疊方法。First, a folding method of the cold box 1 will be described.

圖4a～圖4d係用以將圖1a～圖1c、圖2a、圖2b、圖3a、及圖3b所示之保冷箱1的折疊方法加以說明之外觀立體圖。4a to 4d are external perspective views for explaining a folding method of the cold-insulation box 1 shown in Figs. 1a to 1c, 2a, 2b, 3a, and 3b.

於將圖1a～圖1c、圖2a、圖2b、圖3a、及圖3b所示之保冷箱1加以折疊之情形下，首先如圖4a所示，於蓋部11a、11b及搖蓋部51a、51b係開啟狀態下，放下絕熱板22c、22d。In the case where the cold-insulation box 1 shown in FIGS. 1a to 1c, 2a, 2b, 3a, and 3b is folded, first, as shown in FIG. 4a, in the cover portions 11a, 11b and the flap portion 51a. When the 51b is in the open state, the heat insulating plates 22c and 22d are lowered.

圖5a～圖5c係用以說明圖1a～圖1c、圖2a、圖2b、圖3a、及圖3b所示之保冷箱1之中放下絕熱板22c、22d之際的效應加之剖面圖。5a to 5c are cross-sectional views for explaining the effects of placing the heat insulating plates 22c and 22d in the cold-insulation box 1 shown in Figs. 1a to 1c, 2a, 2b, 3a, and 3b.

於圖1a～圖1c、圖2a、圖2b、圖3a、及圖3b所示之保冷箱1之中放下絕熱板22c、22d之情形下，首先如圖5a所示，使絕熱板22C以底面13側的端邊之與絕熱板23的接合部分為中心，從疊合在側面12c之狀態轉動，並定為抵接於絕熱板23而載置在絕熱板23上之狀態。藉此，絕熱板22c成為朝向於底面13之狀態。In the case where the heat insulating plates 22c, 22d are placed in the cold-insulation box 1 shown in Figs. 1a to 1c, 2a, 2b, 3a, and 3b, first, as shown in Fig. 5a, the heat insulating plate 22C is bottomed. The end portion of the 13 side is centered on the joint portion with the heat insulating plate 23, and is rotated from the state of being superposed on the side surface 12c, and is placed in contact with the heat insulating plate 23 to be placed on the heat insulating plate 23. Thereby, the heat insulating plate 22c is in a state of facing the bottom surface 13.

其次，如圖5b所示，使絕熱板22d以底面13側的端邊之與非折曲部24的接合部分為中心，而從疊合在側面12d之狀態轉動。如此一來，則如同上述，絕熱板22c、22d具有於定為分別朝向於底面13之狀態之情形下其一部分彼此疊合的高度，因此如圖5c所示，絕熱板22d之與非折曲部24之接合部分為相反側之邊側區域，成為抵接於絕熱板22c、且朝向於底面13之狀態。此際，非折曲部24的高度與絕熱板22c的厚度同等，因此絕熱板22d的朝上的面成為與底面13約略平行的狀態。Then, as shown in Fig. 5b, the heat insulating plate 22d is rotated from the side where the end side of the bottom surface 13 side and the non-buckling portion 24 are centered, and is superposed on the side surface 12d. In this way, as described above, the heat insulating plates 22c, 22d have a height at which a part thereof overlaps with each other in a state of being oriented toward the bottom surface 13, respectively, so that the heat insulating plate 22d is non-flexed as shown in Fig. 5c. The joint portion of the portion 24 is a side portion on the opposite side, and is in contact with the heat insulating plate 22c and facing the bottom surface 13. At this time, since the height of the non-bending portion 24 is equal to the thickness of the heat insulating plate 22c, the upward facing surface of the heat insulating plate 22d is approximately parallel to the bottom surface 13.

如同上述，將絕熱板22c、22d放下並定為與底面13相向之狀態後，如圖4b所示，放下絕熱板22a、22b。As described above, after the heat insulating plates 22c and 22d are placed down and set to face the bottom surface 13, the heat insulating plates 22a and 22b are lowered as shown in Fig. 4b.

圖6a及圖6b係用以說明將圖1a～圖1c、圖2a、圖2b、圖3a、及圖3b所示之保冷箱1之中放下絕熱板22a、22b之際的效應之剖面圖。6a and 6b are cross-sectional views for explaining the effect of placing the heat insulating plates 22a and 22b in the cold-insulation box 1 shown in Figs. 1a to 1c, 2a, 2b, 3a, and 3b.

圖1a～圖1c、圖2a、圖2b、圖3a、及圖3b所示之保冷箱1之中，將絕熱板22c、22d如同上述放下而定為與底面13相向之狀態後，並再放下絕熱板22a、22b之情形下，因為下述理由，所以如圖6a所示，能將絕熱板22a、22b同時放下：絕熱板22a、22b具有於分別定為朝向於底面13之狀態之情形下彼此不疊合之高度。In the cold-insulation box 1 shown in Figs. 1a to 1c, 2a, 2b, 3a, and 3b, the heat insulating plates 22c and 22d are placed in a state of being opposed to the bottom surface 13 as described above, and then placed down. In the case of the heat insulating plates 22a and 22b, the heat insulating plates 22a and 22b can be simultaneously lowered as shown in Fig. 6a for the following reasons: the heat insulating plates 22a and 22b are disposed in a state of being oriented toward the bottom surface 13, respectively. The height that does not overlap each other.

而且，如同上述，底面13所安裝之絕熱板23上，成為載置有其一部分係以疊合狀態放下之絕熱板22c、22d之狀態，因此如圖6b所示，成為以下狀態：絕熱板22c、22d中之成為上側之絕熱板22d上載置有絕熱板22a、22b。此際，如同上述，非折曲部25的高度與將絕熱板22c、22d疊合之厚度同等，因此於絕熱板22a、22b倒下而朝向於底面13之狀態下，絕熱板22a、22b的朝上的面成為與底面13約略平行的狀態。Further, as described above, the heat insulating plate 23 to which the bottom surface 13 is attached is in a state in which a part of the heat insulating plates 22c and 22d which are placed in a stacked state is placed, and as shown in FIG. 6b, the heat insulating plate 22c is in a state of the following state: In the upper and lower heat insulating plates 22d of 22d, the heat insulating plates 22a and 22b are placed thereon. In this case, as described above, the height of the non-bending portion 25 is equal to the thickness at which the heat insulating plates 22c and 22d are overlapped. Therefore, in the state where the heat insulating plates 22a and 22b are fallen down toward the bottom surface 13, the heat insulating plates 22a and 22b are The upward facing surface is approximately parallel to the bottom surface 13.

如同上述，當絕熱板22a～22d全部倒下而定為朝向於底面13之狀態時，則因側面12a～12d係由鋁薄片構成而失去側面12a～12d的自立性，當將收納容器的上端部往下方推壓時，則圖4c所示，能折疊收納容器。As described above, when all of the heat insulating plates 22a to 22d are fallen and are oriented toward the bottom surface 13, the side faces 12a to 12d are made of an aluminum foil, and the self-supporting properties of the side faces 12a to 12d are lost, when the upper end of the storage container is to be closed. When the portion is pushed downward, as shown in Fig. 4c, the storage container can be folded.

於此，說明折疊收納容器之際側面12a～12d的效應。Here, the effect of folding the side surfaces 12a to 12d of the storage container will be described.

圖7a～圖7c用以說明將圖1a～圖1c、圖2a、圖2b、圖3a、及圖3b所示之保冷箱1之中折疊收納容器之際側面12a～12d的效應，且係從頂面側觀察保冷箱1。7a to 7c are views for explaining the effects of folding the side surfaces 12a to 12d of the cold storage box 1 shown in Figs. 1a to 1c, 2a, 2b, 3a, and 3b into the storage container, and are The cold storage tank 1 is observed on the top side.

圖1a～圖1c、圖2a、圖2b、圖3a、及圖3b所示之保冷箱1如同上述，收納容器的四個側面中彼此相向之一組側面12a、12b分別構成為：由「以沿著其側面12a、12b的上下的端邊之區域分別作為第一邊、在第一邊之間共有第二邊、第一邊長於第二邊」之二個等腰梯形區域14a、14b構成之區域，較等腰梯形區域14a、14b的外側中之「二個等腰梯形的腰」與「側面12a、12b之與側面12c、12d的連接邊」所圍繞之三角區域16a、16b更硬，且在第二邊可折疊。因此，側面12a、12b之中，當從如圖7a所示地未折疊狀態而將收納容器的上端部往下方推壓時，則圖7b所示，二個等腰梯形區域14a、14b以形成第二邊的部分成為頂點而向收納容器的內側突出之方式折疊，且側面12a、12b一併沿著二個等腰梯形區域14a、14b的外形而折疊，「二個略等腰梯形的腰」與「側面12a、12b之與側面12c、12d的連接邊」所圍繞之三角區域16a、16b係以夾在等腰梯形區域14a、14b之方式折疊。1A to 1c, 2a, 2b, 3a, and 3b, the cold storage box 1 is as described above, and one of the four side faces 12a and 12b of the four sides of the storage container is configured to be The two isosceles trapezoidal regions 14a, 14b are formed along the upper and lower end sides of the side faces 12a, 12b as the first side, the second side sharing the first side, and the first side being longer than the second side. The area is harder than the triangular regions 16a, 16b surrounded by the "two isosceles trapezoidal waists" and the "connecting sides of the side faces 12a, 12b to the side faces 12c, 12d" in the outer sides of the isosceles trapezoidal regions 14a, 14b. And can be folded on the second side. Therefore, among the side faces 12a and 12b, when the upper end portion of the container is pushed downward from the unfolded state as shown in Fig. 7a, the two isosceles trapezoidal regions 14a, 14b are formed as shown in Fig. 7b. The second side portion is apexed and protrudes toward the inside of the storage container, and the side faces 12a, 12b are folded along the outer shape of the two isosceles trapezoidal regions 14a, 14b, "two slightly isosceles trapezoidal waists The triangular regions 16a and 16b surrounded by the "connecting sides of the side faces 12a, 12b and the side faces 12c, 12d" are folded so as to be sandwiched by the isosceles trapezoidal regions 14a, 14b.

而且，將側面12a、12b如上所述折疊，藉以如圖7c所示，側面12c、12d之中折疊成於橫向對折，使與側面12a、12b之連接部分的附近夾在等腰梯形區域14a、14b。Further, the side faces 12a, 12b are folded as described above, whereby as shown in Fig. 7c, the side faces 12c, 12d are folded to be folded in the lateral direction, and the vicinity of the joint portion with the side faces 12a, 12b is sandwiched in the isosceles trapezoidal region 14a, 14b.

如上所述將側面12a～12d折疊後，如圖4d所示，於封閉蓋部11b後封閉蓋部11a。而且，使蓋部11a的黏扣帶31與蓋部11b的黏扣帶接合。又，將搖蓋部51a、51b折疊而使搖蓋部51a、51b的黏扣帶36接合至蓋部11a、11b的黏扣帶。再者，使安裝在底面13之帶體28橫跨保冷箱1的側面12a、12b而接合至帶體28的黏扣帶33與搖蓋部51a、51b的黏扣帶35，將保冷箱1定為折疊狀態。After folding the side faces 12a to 12d as described above, as shown in Fig. 4d, the lid portion 11a is closed after closing the lid portion 11b. Further, the fastening tape 31 of the lid portion 11a is joined to the fastening tape of the lid portion 11b. Further, the flap portions 51a and 51b are folded so that the fastening tapes 36 of the flap portions 51a and 51b are joined to the fastening tapes of the lid portions 11a and 11b. Further, the belt body 28 attached to the bottom surface 13 is joined to the side surface 12a, 12b of the cold box 1 to be bonded to the fastening tape 33 of the belt body 28 and the fastening tape 35 of the flap portions 51a, 51b, and the cold box 1 is placed. Set to collapse.

如上所述將保冷箱1折疊，且因為側面12a、12b具有如上述構成，所以於將四個絕熱板22a～22d分別從疊合在收納容器的側面12a～12d之狀態轉動至朝向於底面13之狀態後，將收納容器的上端部向下方推壓，藉以使收納容器不褶皺而折疊為規定之形狀。藉此，即使於具有絕熱板之構成亦能迅速輕易地折疊。Since the cold-insulation box 1 is folded as described above, and since the side faces 12a and 12b have the above-described configuration, the four heat insulating plates 22a to 22d are respectively rotated from the state of being superposed on the side faces 12a to 12d of the container to the bottom face 13 After that, the upper end portion of the storage container is pushed downward, so that the storage container is folded into a predetermined shape without wrinkles. Thereby, even the structure having the heat insulating plate can be folded quickly and easily.

如同上述折疊之保冷箱1，只要於保持為使側面12d成為上側之狀態抓持手柄29，則能不開啟蓋部11a、11b而簡單地搬運。As described above, the cold-retaining box 1 can be easily transported without opening the lid portions 11a and 11b as long as the handle 29 is gripped while the side surface 12d is held on the upper side.

此外，等腰梯形區域14a、14b亦可係第一邊與第二邊不平行、或腰部不成為相等長度之近似於梯形的形狀，將此等包含定義為略等腰梯型。Further, the isosceles trapezoidal regions 14a, 14b may be shaped such that the first side and the second side are not parallel, or the waist portion is not equal to a trapezoidal shape, and the inclusions are defined as a slightly isosceles ladder type.

其次，說如同上述折疊之保冷箱1的組裝方法。Next, a method of assembling the cold storage box 1 as described above is said.

圖8a～圖8d係用以說明將圖1a～圖1c、圖2a、圖2b、圖3a、及圖3b14所示之保冷箱1的組裝方法之外觀立體圖。8a to 8d are perspective views showing the appearance of a method of assembling the cold-insulation box 1 shown in Figs. 1a to 1c, 2a, 2b, 3a, and 3b14.

於將如同上述折疊之保冷箱1加以組裝之情形下，首先如圖8a所示，從搖蓋部51a、51b的黏扣帶35剝離帶體28的黏扣帶33，且從蓋部11a、11b的黏扣帶剝離搖蓋部51a、51b的黏扣帶36，而開啟搖蓋部51a、51b。而且更從蓋部11a的黏扣帶31剝離蓋部11b的黏扣帶，而開啟蓋部11a、11b。In the case of assembling the cold-insulation box 1 as described above, first, as shown in FIG. 8a, the fastening tape 33 of the belt body 28 is peeled off from the fastening tape 35 of the flap portions 51a, 51b, and from the lid portion 11a, The fastening tape of 11b peels off the fastening tape 36 of the flap portions 51a, 51b, and opens the flap portions 51a, 51b. Further, the fastening tape of the lid portion 11b is peeled off from the fastening tape 31 of the lid portion 11a, and the lid portions 11a, 11b are opened.

而且，將收納容器的上端部往上方拉提而伸展側面後，如圖8b所示，將絕熱板22a、22b分別以底面13側的端邊之與非折曲部25的接合部分為中心，從朝向於底面13之狀態轉動，而定為疊合在側面12a、12b之狀態。此際，因等腰梯形區域14a、14b硬而側面12a、12b容易成為約略伸張狀態，容易使絕熱板22a、22b從朝向於底面13之狀態轉動至疊合在側面12a、12b之狀態。Further, after the upper end portion of the storage container is pulled upward and the side surface is extended, as shown in FIG. 8b, the heat insulating plates 22a and 22b are respectively centered on the joint portion of the end side on the bottom surface 13 side and the non-curved portion 25. Rotating from the state toward the bottom surface 13 is defined as being superimposed on the side faces 12a, 12b. In this case, the isopic trapezoidal regions 14a and 14b are hard and the side faces 12a and 12b are likely to be approximately stretched, and the heat insulating plates 22a and 22b are easily rotated from the state toward the bottom face 13 to the side faces 12a and 12b.

將絕熱板22a、22b定為疊合在側面12a、12b之狀態後，如圖8c所示，使絕熱板22d以底面13側的端邊之與非折曲部24的接合部分為中心，而從朝向於底面13之狀態轉動，定為疊合在側面12d之狀態。又，使絕熱板22c以底面13側的端邊之與絕熱板23的接合部分為中心，而從朝向於底面13之狀態轉動，定為疊合在側面12c之狀態。After the heat insulating plates 22a and 22b are stacked on the side faces 12a and 12b, as shown in FIG. 8c, the heat insulating plate 22d is centered on the joint portion of the end side on the bottom surface 13 side and the non-buckling portion 24, and Rotation from the state toward the bottom surface 13 is defined as a state of being superposed on the side surface 12d. In addition, the heat insulating plate 22c is rotated from the end portion on the bottom surface 13 side to the joint portion of the heat insulating plate 23, and is rotated from the state toward the bottom surface 13, and is superposed on the side surface 12c.

當絕熱板22c、22d成為分別疊合在側面12c、12d之狀態時，則絕熱板22c、22d的寬度分別成為以下寬度：從側面12c、12d的寬度減去絕熱板22a、22b的厚度；因此如圖8d所示，絕熱板22c、22d的兩端部成為與絕熱板22a、22b抵接之狀態。藉此，將絕熱板22a～22d保持成疊合在側面12a～12d之狀態。When the heat insulating plates 22c and 22d are superposed on the side faces 12c and 12d, respectively, the widths of the heat insulating plates 22c and 22d are respectively the following widths: the thickness of the heat insulating plates 22a and 22b is subtracted from the width of the side faces 12c and 12d; As shown in Fig. 8d, both end portions of the heat insulating plates 22c and 22d are in contact with the heat insulating plates 22a and 22b. Thereby, the heat insulating plates 22a to 22d are held in a state of being superposed on the side faces 12a to 12d.

如上所述組裝保冷箱1，且因為側面12a、12b具有如上述構成而被折疊，所以將收納容器的上端部往上方拉提而伸展側面後，能藉由使四個絕熱板22a～22d分別從朝向於收納容器的底面13之狀態轉動至疊合在側面12a～12d之狀態，而迅速輕易地組裝、且於具有絕熱板之構成亦迅速輕易地組裝。Since the cold storage box 1 is assembled as described above, and since the side surfaces 12a and 12b are folded as described above, the upper end portions of the storage container are pulled upward and the side surfaces are extended, and the four heat insulating plates 22a to 22d can be respectively separated. From the state of being oriented toward the bottom surface 13 of the storage container to the state of being superposed on the side faces 12a to 12d, it is quickly and easily assembled, and the structure having the heat insulating plate is quickly and easily assembled.

此外，本形態之中，等腰梯形區域14a、14b係二枚鋁薄片疊合而構成，且等腰梯形區域14a、14b的邊界部分一併形成有痕線15，此外，三角區域16a、16b係由一枚鋁薄片構成，藉由上述而等腰梯形區域14a、14b構成之區域構成如下：較「等腰梯形區域14a、14b的腰」與「側面12a、12b之與側面12c、12d的連接邊」所圍繞之三角區域16a、16b更硬，且在等腰梯形區域14a、14b的邊界部分可折疊。但亦可使等腰梯形區域14a、14b與三角區域16a、16b之材質或厚度不同，藉以將等腰梯形區域14a、14b定為較三角區域16a、16b更硬之構成。Further, in the present embodiment, the isosceles trapezoidal regions 14a and 14b are formed by laminating two aluminum sheets, and the boundary portions of the isosceles trapezoidal regions 14a and 14b are collectively formed with the traces 15 and the triangular regions 16a and 16b. It is composed of an aluminum foil, and the regions formed by the above-described isosceles trapezoidal regions 14a, 14b are formed as follows: "waist of the isosceles trapezoidal regions 14a, 14b" and "sides 12a, 12b and the side faces 12c, 12d" The triangular regions 16a, 16b surrounded by the connecting edges are harder and are foldable at the boundary portions of the isosceles trapezoidal regions 14a, 14b. However, the isosceles trapezoidal regions 14a and 14b may be made different in material or thickness from the triangular regions 16a and 16b, whereby the isosceles trapezoidal regions 14a and 14b may be formed to be harder than the triangular regions 16a and 16b.

又，收納容器的頂面構成為藉由二個蓋部11a、11b而自由開閉，但亦可構成為藉由與側面12a～12d中之一側面連接之一蓋部而自由開閉。又，蓋部亦可係可拆卸者。Further, the top surface of the storage container is configured to be openable and closable by the two lid portions 11a and 11b. However, the lid portion may be opened and closed by being connected to one of the side surfaces 12a to 12d. Moreover, the cover portion can also be a detachable person.

又，蓋部11a、11b及底面13亦可由不具可撓性之薄片構成。Further, the lid portions 11a and 11b and the bottom surface 13 may be formed of a sheet having no flexibility.

再者，收納容器的形狀亦可非長方體而係立方體。其中，於收納容器的形狀係立方體之情形下，上述絕熱板22a、22b亦於定為朝向於底面13之狀態之情形下其一部疊合，因此須使非折曲部25的高度彼此不同。Further, the shape of the storage container may be a cube without a rectangular parallelepiped. In the case where the shape of the storage container is a cube, the heat insulating plates 22a and 22b are also overlapped in a state of being oriented toward the bottom surface 13, so that the heights of the non-bending portions 25 are different from each other. .

〔另一實施形態〕 圖9a係本發明之保冷箱的另一實施形態中之頂面係開啟狀態之外觀立體圖。圖9b係圖9a所示之保冷箱101的頂面係封閉狀態之外觀立體圖。圖9c係圖9a所示之保冷箱101係折疊狀態之外觀立體圖。[Other Embodiments] Fig. 9a is an external perspective view showing a state in which a top surface is opened in another embodiment of the cold-insulation container of the present invention. Fig. 9b is an external perspective view showing the state in which the top surface of the cold insulation box 101 shown in Fig. 9a is closed. Fig. 9c is an external perspective view showing the cold box 101 shown in Fig. 9a in a folded state.

本形態如圖9a～圖9c所示，相較於圖1a～圖1c、圖2a、圖2b、圖3a、及圖3b所示者，蓋部111a、111b之與側面112c、112d的連接方向的長度十分不同，藉此，兩者相異之處如下：安裝在蓋部111a、111b之絕熱板121a、121b的形狀彼此不同。此原因如下：本形態的保冷箱101之中，使蓋部111a之與側面121c的連接方向的長度同等於側面112c的高度，藉以使蓋部111a的長度相較於蓋部111b的長度，長「於蓋部111a、111b係封閉之際疊合在蓋部111b之區域的寬度」以上。This embodiment is shown in FIGS. 9a to 9c, and the connection directions of the cover portions 111a and 111b to the side faces 112c and 112d are shown in comparison with those shown in Figs. 1a to 1c, 2a, 2b, 3a, and 3b. The lengths are quite different, whereby the difference between the two is as follows: the shapes of the heat insulating plates 121a, 121b attached to the lid portions 111a, 111b are different from each other. The reason is as follows: In the cold-insulation box 101 of the present embodiment, the length of the lid portion 111a in the direction of connection with the side surface 121c is made equal to the height of the side surface 112c, so that the length of the lid portion 111a is longer than the length of the lid portion 111b. The width of the region where the lid portions 111a and 111b are overlapped in the lid portion 111b is "above".

以下，說明如上述構成之保冷箱101所成之特有效果。Hereinafter, the specific effects of the cold storage box 101 configured as described above will be described.

圖10係顯示下者狀態之剖面圖：將圖9a～圖9c所示之保冷箱101之中絕熱板122a～122d分別倒下成朝向於底面113之狀態。Fig. 10 is a cross-sectional view showing the state in which the heat insulating plates 122a to 122d in the cold-insulation box 101 shown in Figs. 9a to 9c are respectively turned down toward the bottom surface 113.

於絕熱板122a～122d全部倒下而朝向於底面113之狀態下，因側面112a～112d係由鋁薄片構成，而失去側面112a～112d的自立性。然而，蓋部111a之與側面121c的連接方向的長度成為與側面112c的高度同等，且蓋部111a在其約略整面安裝有絕熱板121a，因此如圖10所示，側面112c成為豎起狀態。藉此，將保冷箱101加以組裝之際，容易將成為與底面113相向狀態之絕熱板122a、122b轉動至疊合在側面112a、112b之狀態。In a state in which all of the heat insulating plates 122a to 122d are lowered and directed toward the bottom surface 113, the side faces 112a to 112d are made of an aluminum foil, and the self-supporting properties of the side faces 112a to 112d are lost. However, the length of the cover portion 111a in the connection direction with the side surface 121c is equal to the height of the side surface 112c, and the cover portion 111a is attached with the heat insulating plate 121a on the substantially entire surface thereof, so that the side surface 112c is erected as shown in FIG. . As a result, when the cold-insulation box 101 is assembled, it is easy to rotate the heat-insulating plates 122a and 122b which are opposed to the bottom surface 113 to be superposed on the side faces 112a and 112b.

此外，蓋部111a之未安裝有絕熱板121a的區域之中，在二枚鋁薄片間，夾設有由聚丙烯構成之1mm厚的樹脂薄片用以保持固定強度，因此亦由此樹脂薄片支持側面112c。但，藉由將絕熱板121a安裝在蓋部111a的約略整面，而即使蓋部111a之未安裝有絕熱板121a的區域不夾設有樹脂薄片，側面112c亦保持豎起狀態。此外，藉由在蓋部111a的周緣部形成痕線（不圖示），亦能提昇蓋部111a之未安裝有絕熱板121a的區域的強度。Further, among the regions of the lid portion 111a where the heat insulating plate 121a is not attached, a 1 mm thick resin sheet made of polypropylene is interposed between the two aluminum sheets to maintain the fixing strength, and thus the resin sheet is supported thereby. Side 112c. However, by attaching the heat insulating plate 121a to the substantially entire surface of the lid portion 111a, even if the resin sheet is not interposed in the region where the heat insulating plate 121a is not attached to the lid portion 111a, the side surface 112c is kept in the upright state. Further, by forming a trace (not shown) on the peripheral portion of the lid portion 111a, the strength of the region of the lid portion 111a where the heat insulating plate 121a is not attached can be lifted.

圖11a係本發明之保冷箱的另一實施形態中之頂面係開啟狀態的外觀立體圖。圖11b係圖11a所示之保冷箱201的頂面係封閉狀態的外觀立體圖。圖11c係將圖11a所示之保冷箱201係折疊狀態加以顯示之外觀圖。Fig. 11a is an external perspective view showing a state in which the top surface is opened in another embodiment of the cold box of the present invention. Fig. 11b is an external perspective view showing the state in which the top surface of the cold insulation box 201 shown in Fig. 11a is closed. Fig. 11c is an external view showing the state in which the cold box 201 shown in Fig. 11a is folded.

本形態如圖11a～圖11c所示，相較於圖1a～圖1c、圖2a、圖2b、圖3a、及圖3b所示者，則側面212d及與其相向之側面（圖11a～圖11c未表示）、側面212a及與其相向之側面（圖11a～圖11c未表示）的構成不同。This embodiment is shown in Figs. 11a to 11c, and the side surface 212d and the side surface facing it are the same as those shown in Figs. 1a to 1c, 2a, 2b, 3a, and 3b (Fig. 11a - Fig. 11c). The configuration of the side surface 212a and the side surface opposite thereto (not shown in FIGS. 11a to 11c) are different.

本形態中之側面212d及與其相向之側面，分別由蓋部11a、11b側的上側區域217a、及底面側的下側區域217b構成。上側區域217a係在一枚鋁薄片之保冷箱201的內側的面疊合面料（布）而構成。下側區域217b係由一枚鋁薄片構成。藉此，上側區域217a較下側區域217b更硬。此等上側區域217a與下側區域217b之邊界形成有痕線218。痕線218在與等腰梯形區域14a、14b的第二邊相同的高度之中，分別平行於「側面212d及與其相向之側面」與「蓋部11b、11a」之邊界而延伸。The side surface 212d and the side surface facing the same in this embodiment are composed of an upper side region 217a on the side of the lid portions 11a and 11b and a lower side region 217b on the bottom surface side. The upper side region 217a is formed by laminating a fabric (cloth) on the inner side of the cold-storage box 201 of an aluminum foil. The lower side region 217b is composed of one aluminum foil. Thereby, the upper side region 217a is harder than the lower side region 217b. A line 218 is formed at the boundary between the upper side region 217a and the lower side region 217b. The traces 218 extend parallel to the boundary between the "side surface 212d and the side surface facing the side" and the "cover portions 11b, 11a" at the same height as the second side of the isosceles trapezoidal regions 14a, 14b.

又，本形態中之側面212a及與其相向之側面分別在三角區域16a、16b各者形成有：痕線219，從形成在側面212d及與其相向之側面之痕線218延伸。Further, in the side surface 212a and the side surface facing the same in the present embodiment, each of the triangular regions 16a and 16b is formed with a trace 219 extending from the side surface 212d and the side line 218 facing the side surface.

於如上述構成之保冷箱201，亦與圖1a～圖1c、圖2a、圖2b、圖3a、及圖3b所示者同樣折疊、組裝。此際，側面212d及與其相向之側面之中，上側區域217a與與下側區域217b之邊界形成有痕線218，藉以使上側區域217a與下側區域217b之邊界部分容易折疊。又，於側面212a及與其相向之側面，三角區域16a、16b亦經由痕線219而變得容易折疊。再者，上側區域217a變得較下側區域217b更硬，藉以維持上側區域217a係伸長狀態而直接折疊保冷箱20，側面212d及與其相向之側面不易褶皺。The cold-insulation box 201 having the above configuration is also folded and assembled in the same manner as those shown in Figs. 1a to 1c, 2a, 2b, 3a, and 3b. At this time, among the side faces 212d and the side faces facing therewith, a line 218 is formed at the boundary between the upper side region 217a and the lower side region 217b, whereby the boundary portion between the upper side region 217a and the lower side region 217b is easily folded. Further, the triangular regions 16a and 16b are also easily folded by the traces 219 on the side faces 212a and the side faces facing them. Further, the upper region 217a is made harder than the lower region 217b, whereby the upper region 217a is stretched and the cold box 20 is directly folded, and the side surface 212d and the side surface facing it are less likely to wrinkle.

此外，亦於圖1a～圖1c及圖9a～圖9c所示之保冷箱1、101之中，側面12a、112a及與其相向之側面的三角區域16a、16b、116a、116b各者亦可形成有與圖11a～圖11c所示之痕線219同樣的痕線。Further, in the cold-insulation boxes 1 and 101 shown in FIGS. 1a to 1c and 9a to 9c, the side faces 12a and 112a and the triangular regions 16a, 16b, 116a, and 116b facing the side faces thereof may be formed. There are the same traces as the trace 219 shown in Figs. 11a to 11c.
