[Prior art]

 In the above paper box, a transparent plastic film is stuck on the inner surface of the top plate except for the handle, and when the handle is cut and raised during carrying, the cut-and-raised hole is closed. In order to prevent the deterioration of the refrigerated decoration cake when carrying it, use ice packs (freeze a pack of water or a gel-like cooling agent that is hermetically sealed with a plastic flexible sheet). It is known that cold bodies such as dried ice cream and dry ice are stored in a box together with a decoration cake.

[0003]

[Problems to be solved by the invention]

 However, there has been a problem that, as in the past, simply storing the cool insulator in the space inside the box after storing the decoration cake does not allow the cool air to spread throughout the box and only partially cools the box. In view of the above, it is a main object of the present invention to provide a cold storage body storage structure in a paper box for storing a cold storage body in a box so that cool air can be distributed throughout the box.

[0004]

[Means for Solving the Problems]

[Action]

 In the cold box housing structure of the paper box according to the present invention, in a paper box provided with a handle for carrying a hand formed by partially cutting and raising the top board, a tubular or bag-shaped housing portion made of a flexible sheet material is provided. It is formed on the inner surface, the cut-and-raised hole of the handle is closed by the housing portion, and the cooler is stored and held in the ceiling of the box, so the air in the ceiling of the box is cooled by the cooler and the inside of the box is cooled. Since the cool air is lowered from the ceiling of the box, the cool air can be showered on the objects to be kept cool in the box, and the cool air can be cooled throughout the box from corner to corner and from bottom to top. Thereby, the object to be kept cool in the box can be efficiently kept cool.

[0009] The housing portion has a square top sheet portion having one surface adhered to the inner surface of the top plate except for the handle portion to close the cut-out hole, and the other surface of the top sheet portion. The upper and lower sheets are fixed to each other to form a cylindrical or bag-shaped receiving section, and a fixed lower edge section is formed between the upper and lower sheet sections. Since the cooling body is stored and held in the box, the cut-and-raised hole of the handle in the paper box provided with the handle for the hand which is formed by partially cutting and raising the top plate is closed, and the cooling body at the ceiling inside the box is closed. It is possible to appropriately obtain a storage part that also serves as storage and holding.

In addition, since at least the upper sheet portion is formed of a transparent or translucent plastic film, the inside of the housing can be seen from the outside of the box through the cut-and-raised hole, and whether the cold insulator has been housed in the housing. It is possible to confirm whether or not it is possible to forget to insert the cool insulator.

Further, since at least the lower sheet portion is formed of a nonwoven fabric, it is possible to prevent dew condensation from occurring on the lower surface of the storage portion, and to reduce the commercial value by dropping water from the storage portion onto the object to be kept cool. Can be prevented.

[0012]

It is a perspective view of the bag-shaped container which forms.

The paper box 1 shown in FIGS. 1 to 4 is used to carry a round decoration cake or the like having a diameter of about 20 cm, for example, and is composed of a single paper box mount 1A as shown in FIG. . The paper box mount 1A includes an adhesive strip 2, a square bottom plate 3, a square left side wall 4, a top plate 5 having the same shape as the bottom plate 3, and a right side wall 6 having the same shape as the left side wall 4 in this order from the left. The right side of the left and right side walls 4, 6 are connected to the flaps 15, 16, 17, 18 via the folds 11, 12, 13, 14 at the upper and lower edges thereof. A rear cover plate 21 and a front cover plate 22, which are the same square rear wall and front wall, are connected to the upper and lower edges of the bottom plate 3 via folds 19 and 20, respectively. A rear lid pressing plate 25 and a front lid pressing plate 26 of the same shape are connected to each other via folds 23 and 24. In addition, the rear insertion piece 29 and the front insertion piece 30 extend from the center of the tip of each of the lid holding plates 25 and 26 through the folds 27 and 28, and a U-shaped one is provided at the center of each of the lid plates 21 and 22. The rectangular push-in pieces 35 and 36 are formed so as to be able to be pushed in through the cuts 31 and 32 and one fold 33 and 34 provided between the ends of the cuts 31 and 32. Further, two semi-circular cuts (37, 38) and (39, 40) on the inner and outer sides of the top plate 5 and ends of two semi-circular cuts (37, 38) and (39, 40) on the inner and outer sides are formed. A pair of semicircular handles 45, 46 are formed so as to be freely cut and raised via two left and right folds (41, 42), (43, 44) provided between the portions. Further, small holes 47 and 48 for cutting and raising the handles are formed in portions of the top plate 5 along the inner edges of the handles 45 and 46.

In the paper box mount 1A, the bottom plate 3 and the right side wall 6 are folded under the left side wall 4 and the top plate 5 via folds 8 and 10 so as to overlap with each other. The right side wall 6 is folded and integrally connected via an adhesive piece 2 coated with an adhesive, that is, is delivered and stored in a cake shop as a paper box 1 folded flat. By pushing the left and right side edges, that is, the folds 8 and 10 inward, the folded paper box 1 causes the left and right side walls 4 and 6 to stand upright, and the bottom plate 3 and the top plate 5 move away from each other with the operation. Then, the left and right flaps 15, 17 extending from the rear edges of the left and right side walls 4, 6 of the rectangular tubular paper box 1 are assembled into a horizontal rectangular tubular paper box 1 having open front and rear side surfaces. Fold inward through folds 11 and 13 Then, the rear lid plate 21 extending from the rear edge of the bottom plate 3 is bent inward through the fold 19, and finally, the rear lid pressing plate 25 extending from the rear edge of the top plate 5 through the fold 23. While being bent inward, the rear insertion piece 29 extending from the center of the front end of the rear lid pressing plate 25 is inserted into the insertion groove formed in the center of the rear lid plate 21 by pushing the rear insertion piece 35 into the inside. By inserting and holding the rear side surface (one rectangular opening) of the rectangular cylindrical paper box 1 closed, only the front side surface (the other rectangular cylindrical opening) shown in FIG. 1 is opened. After the decoration cake 49 is accommodated in the paper box 1 from the front side opened in the assembled state and opened in the assembled state, the decoration cake 49 is extended from the front edge of the left and right side walls 4 and 6 of the paper box 1. Left and right flaps 16, 18 The front cover plate 22 which is bent inward through the notches 12 and 14 and then extends from the front edge of the bottom plate 3 is bent inward through the fold 20 and finally the front cover plate which extends from the front edge of the top plate 5 While bending the holding plate 26 inward through the crease 24, the front insertion piece 30 extending from the center of the front end of the front cover holding plate 26 is pushed into the inside of the pressing piece 36 so that the front cover plate 22 is By inserting the paper box 1 into the insertion groove formed at the center and closing and holding the front side (the other opening of the rectangular cylinder) of the paper box 1, the rear side and the front side (the rectangular cylinder) as shown in FIG. (Both openings) are assembled in the closed paper box 1, and the decoration cake 49 is accommodated in the paper box 1.

After the decoration cake 49 is accommodated in the paper box 1, a fingertip is inserted into small holes 47, 48 formed in the top plate 5, and the fingertip is hooked on a pair of handles 45, 46. By lifting, the pair of handles 45, 46 are cut through the cuts (37, 38), (39, 40) and the folds (41, 42), (43, 44) as shown in FIGS. The paper box 1 is cut and raised from the top 5 and stands upright on the upper surface of the top plate 5. The pair of handles 45 and 46 allow the paper box 1 to be carried by hand.

By the way, in order to prevent the deterioration of the decoration cake 49 that needs to be refrigerated when carrying it, an ice pack (a pack of water or a gel-like cooling agent hermetically sealed with a plastic flexible sheet is frozen. It is known that a cold insulator 50 such as dried ice cream or dry ice is stored in the paper box 1 together with the decoration cake 49. However, as in the conventional case, the inside of the paper box 1 after the decoration cake 49 is stored therein. There is a problem in that simply storing the cool insulator 50 in the gap does not allow the cool air to spread throughout the paper box 1 and only partially cools it. Therefore, in the present embodiment, as shown in FIGS. 1, 3, and 4, a paper box provided with a handle 45, 46 for carrying formed by partially cutting and elevating the top plate 5 is made of a flexible sheet material. A cylindrical housing part 51 is formed on the inner surface of the top plate 5, the cut-and-raised holes 45 a and 46 a of the handles 45 and 46 are closed by the housing part 51, and the cool insulator 50 is placed on the ceiling part in the paper box 1. They are housed and held.

Note that an ice pack (one that freezes a pack in which water or a gel-like cooling agent is hermetically sealed with a plastic flexible sheet) is shown as the cooling body 50.

As shown in FIGS. 1, 3 and 4, one surface of the cylindrical housing portion 51 is attached to the inner surface of the top plate 5 except for the handles 45 and 46 by an adhesive, and the handles 45 and 46 are attached. A rectangular upper sheet portion 52 for closing the cut-and-raised holes 45a and 46a, and a predetermined upper surface which overlaps the other surface of the upper surface sheet portion 52 and faces in a direction orthogonal to the open surface (front and rear side surfaces) of the paper box 1. (Left and right edges) are fixed by means of an adhesive or heat fusion, etc., and the cylindrical housing portion 51 with both upper and lower sheet portions 52 facing both open ends toward the open surfaces (front and rear side surfaces) of the paper box 1. Is formed of a square-shaped lower sheet portion 53 for forming the sheet. The cold insulator 50 is accommodated and held between the upper sheet portion 52 and the lower sheet portion 53. The upper sheet portion 52 is made of a transparent or translucent plastic film. While the lower sheet portion 53 is not It is formed of woven fabric.

Further, since the upper sheet portion 52 on the upper surface of the cylindrical housing portion 51 is attached to the inner surface of the rigid top plate 5 except for the handles 45 and 46, the lower sheet portion 53 on the lower surface of the cylindrical housing portion 51. Only the cold storage body 50 is accommodated and held in the tubular housing portion 51 by bending only the lower portion to the lower side. Appropriate loosening (the upper sheet portion 52 and the lower sheet portion 53 of the cylindrical storage portion 51 do not adhere to each other, and the opening end of the cylindrical storage portion 51 is easily expanded, so that the inside of the cylindrical storage portion 51, ie, The cold insulator 50 can be easily inserted between the upper sheet portion 52 and the lower sheet portion 53, and the lower sheet portion 53 of the tubular accommodating portion 51 is bent downward by an amount corresponding to the thickness of the cold insulator 50. Then, the cold insulator 50 is moved to the upper sheet portion 52, namely, the top plate 5 (Slack) that can be stored and held in contact with or as close as possible to the inner surface.

Further, the length (depth) of the cylindrical housing portion 51 is formed to be substantially the same as the depth of the paper box 1, and the front and rear side surfaces of the paper box 1 are closed by the front and rear cover plates 26 and 25. The openings at the front and rear ends of the cylindrical housing portion 51 are closed by the front and rear cover plates 26 and 25 to prevent the cooling body 50 from dropping from the cylindrical housing portion 51 when the paper box 1 is carried, thereby preventing the decoration cake from being damaged. I am trying to do it.

The tubular housing portion 51 is formed on the inner surface of the top plate 5 at the end of the manufacturing process of the cardboard mount 1A. The tubular housing portion 51 is made of a flexible sheet material and has flexibility. In addition, because of the sheet shape, the paper box mount 1A is processed into the folded paper box 1, the paper box 1 is assembled from the folded state, the decoration cake is stored, and the open end of the paper box 1 is closed. The operation and the raising and lowering operations of the handles 45 and 46 are not hindered, and the handling can be performed in exactly the same manner as the conventional paper box of this type. When the folded paper box 1 is assembled into the horizontal rectangular cylindrical paper box 1, the cylindrical housing part 51 moves integrally with the top plate 5 and is formed on the inner surface of the top plate 1 of the rectangular cylindrical paper box 1. Then, when the rear side surface of the rectangular cylindrical paper box 1 is closed by the rear cover plate 21, the opening of the rear end portion of the cylindrical housing portion 51 is thereafter closed by the cover plate 21, and as shown in FIG. When assembling the paper box 1 in which only the side surfaces are opened, and inserting the decoration cake 49 into the paper box 1, the cold insulator 50 is inserted into the cylindrical housing portion 51 from the front opening end of the cylindrical housing portion 51. Then, when the front side surface of the paper box 1 is closed by the front cover plate 22, the front cover plate 22 closes the opening at the front end of the tubular housing portion 51, and the cold insulator 50 is attached to the ceiling portion of the paper box 1. Is stored and held.

As described above, the cold insulator 50 housed and held by the cylindrical housing portion 51 in the ceiling portion of the paper box 1 cools the air in the ceiling portion of the paper box 1. The cool air flows down from corner to corner in the paper box 1 while being showered like a shower on a decoration cake 49, which is an object to be kept cool, housed in the paper box 1 below the cylindrical storage portion 51. This makes it possible to cool the refrigerated decoration cake 49 evenly and uniformly throughout.

As is apparent from the above description, in the paper box 1 provided with the handle 45, 46 for the handbag formed by partially cutting and raising the top plate 5, the cylindrical housing portion 51 made of a flexible sheet material is moved upward. Since the cut-and-raised holes 45a and 46a of the handles 45 and 46 are closed by the housing portion 51 and the cold insulator 50 is housed and held in the ceiling portion of the paper box 1, Since the air in the ceiling portion inside is cooled by the cooler 50 and the cool air is lowered from the ceiling portion in the paper box 1, a shower effect of cold air on the cold storage target 49 in the paper box 1 is obtained, and the inside of the paper box 1 is cooled. Can be cooled from corner to corner and from bottom to top. This allows the cold storage target 49 in the paper box 1 to be efficiently kept cold. The accommodation section 51 has a square upper surface sheet portion for attaching one surface to the inner surface of the top plate 5 except for the handles 45 and 46 to close the cut-and-raised holes 45a and 46a of the handles 45 and 46. 52 and a square lower surface sheet portion 53 for fixing a predetermined edge facing the other surface of the upper surface sheet portion 52 so as to be opposed to the upper surface sheet portion 52 to form a cylindrical accommodating portion 51 with the upper surface sheet portion 52. Since the cold insulator 50 is housed and held between the upper sheet portion 52 and the lower sheet portion 53, the handle in the paper box 1 provided with the handle 45, 46 for carrying formed by partially cutting and raising the top plate 5 is provided. An accommodating portion 51 that functions to close the cut-and-raised holes 45a and 46a of the 45 and 46 and to accommodate and retain the cold insulator 50 at the ceiling portion in the paper box 1 can be appropriately obtained. Further, since at least the upper sheet portion 52 is formed of a transparent or translucent plastic film, the inside of the accommodating portion 51 can be seen from the outside of the paper box 1 through the cut-and-raised holes 45a and 46a of the handles 45 and 46. Can be confirmed whether or not the cold storage body 50 is stored in the storage section 51, and forgetting of the cool insulator 50 can be prevented. Further, since at least the lower sheet portion 53 is formed of a non-woven fabric, it is possible to prevent dew condensation from occurring on the lower surface of the storage portion 51 and to drop water from the storage portion 51 onto the object to be cooled 49, thereby lowering the commercial value. Can be prevented.

The tubular housing portion 51 is formed by fixing the edges of the upper sheet portion 52 and the lower sheet portion 53 facing each other at one opening end portion, so that the cold storage body is moved from one opening end portion. 50 can be used as a bag-shaped storage portion into which a handle 50, which is formed by partially cutting and raising the top plate 5, is provided in place of the tubular storage portion 51. A bag-shaped accommodation portion made of a conductive sheet material is formed on the inner surface of the top plate 5, the cut-and-raised holes 45 a and 46 a of the handles 45 and 46 are closed by the bag-shaped accommodation portion, and The cold insulator 50 may be stored and held. Here, in the case of the bag-shaped storage portion, if only the opening end is extended to one of the front and rear cover plates 22 and 21 (front and rear side surfaces) of the paper box 1, the cooling material 50 from the bag-shaped storage portion can be formed. Since it can be prevented from falling off, there is an advantage that the length (depth) can be made shorter than that of the cylindrical container 51.

The above-mentioned cylindrical or bag-shaped storage section 51 is formed on the top plate 5 of the paperboard mount 1A using one or two flexible sheet materials, There is a method in which a tubular or bag-shaped container is formed from a flexible sheet material, and the container is attached to the inner surface of the top plate 5 of the paperboard mount 1A.

That is, a method of forming the cylindrical or bag-shaped accommodation portion 51 on the top plate 5 of the cardboard mount 1A using a single flexible sheet material will be described. One surface of one side portion when the sheet is folded in two is adhered to the inner surface of the top plate 5 except for the handles 45 and 46 by an adhesive, and then the unattached portion of the flexible sheet is attached. Fold it on the other surface of the part and fold it in two, and fix the edges of the flexible sheet facing the other side of the fold with adhesive or heat sealing, or use the flexible sheet on the opposite side to the fold. By fixing the edge portion directly to the inner surface of the top plate 5 with an adhesive, the cylindrical housing portion 51 made of one flexible sheet material can be formed on the inner surface of the top plate 5, and the folds and Attach the edges of the flexible sheets facing each other on the opposite side When the flexible sheet is further fixed to one of the remaining two side edges at the other side edge of the flexible sheet, the bag-shaped housing made of one flexible sheet material is formed on the inner surface of the top plate 5. A part can be formed.

A method of forming the cylindrical or bag-shaped accommodation portion 51 on the top plate 5 of the cardboard mount 1A using two flexible sheet materials will be described. One square flexible sheet is described. Is adhered to the inner surface of the top plate 5 except for the handles 45 and 46 by an adhesive, and further, the opposite two side edges of another square flexible sheet are directly attached to the top plate 5. The top plate 5 is fixed by using an adhesive or by using an adhesive or heat-sealing or the like to fix the edges of the two opposing side edges of the flexible sheet previously attached to the top plate 5. On the inner surface, a cylindrical accommodating portion 51 made of two flexible sheet materials can be formed, and two opposite side edges of another square flexible sheet are directly connected to the top plate 5. The flexible sheet that has been pasted to the top plate 5 or the two opposite side edges of the flexible sheet. Further, the flexible sheet edge of one of the remaining two side edges is directly fixed to the top plate 5 with an adhesive, or the remaining two side edges of the flexible sheet previously attached to the top plate 5 are attached. The bag-shaped housing portion made of two flexible sheet materials is fixed to the inner surface of the top plate 5 by being fixed to the edge portion of one of the side edges of the flexible sheet by means of an adhesive or heat fusion. Can be formed.

On the other hand, after the cylindrical or bag-shaped housing portion 51 is previously formed into a cylindrical or bag-shaped container with one flexible sheet material, the container is attached to the top plate 5 of the paperboard mount 1A. The method of forming the tape by sticking it to the inner surface of the sheet is as follows. An indefinite length tape-shaped flexible sheet material is folded in two, and the edges of the sheet facing the fold are opposite to each other with adhesive or heat fusion. To form a cylindrical container having an indefinite length, and cutting the indefinite-length cylindrical container into a predetermined size to form a cylindrical container for each paper box 1; When cutting the cylindrical container into the cylindrical containers for each paper box 1, or after cutting, the flexible sheet edges facing each other at one open end of the cylindrical container are bonded with an adhesive or heat. By being fixed and closed by the means described in (1), it is formed in a bag-shaped container for each paper box 1, and the cylindrical or bag-shaped container is formed. The top surface of the top plate 5 is adhered to the inside surface of the top plate 5 except for the handles 45 and 46 by an adhesive, so that the top surface of the top plate 5 has a tubular or bag-like shape made of a single flexible sheet material. Can be formed.

In the above-described method of forming the tubular or bag-shaped receiving portion 51, in the method of forming the receiving portion 51 on the top plate 5, the manufacturing process of the paper box mount 1A is the same as that of the conventional paper box mount of this seed box. The manufacturing cost is high due to a large increase in the number of processes, and the method of forming on the top plate 5 and the method of forming a tubular or bag-shaped container with a single flexible sheet material in advance are not flexible. A slight shift occurs between the fixing position between the flexible sheet and the top plate 5 and the fixing position between the edges of the flexible sheet. An appropriate (subtle) slack cannot be given to the lower sheet portion 53 with respect to 52. Therefore, in this embodiment, the cardboard mount 1A can be manufactured in the same process as the conventional manufacturing process of the cardboard mount of this kind of paper box, and even if the fixing position is slightly shifted, the shape is cylindrical or bag-shaped. A tubular or bag-shaped housing portion 51 is formed by a method capable of imparting an appropriate (subtle) slack to the lower surface sheet portion 53 with respect to the upper surface sheet portion 52 in a stretched state of the housing portion 51. .

That is, the cylindrical or bag-shaped housing portion 51 is formed by forming a cylindrical or bag-shaped container with two flexible sheet materials in advance, and then attaching the container to the top plate 5 of the paper box mount 1A. It is formed by laminating two tape-shaped flexible sheet materials of indefinite lengths with different widths on top of each other. The flexible sheet material is fixed by means of heat fusion or the like, and when one flexible sheet material is in a stretched state, the other flexible sheet material has a predetermined slack to form an indefinite-length cylindrical container. The cylindrical container is cut into a predetermined size to form a cylindrical container 51A for each paper box 1 as shown in FIG. 6, or when an indefinite-length cylindrical container is cut into a predetermined size or cut. Later, the edge of the flexible sheet opposes at one opening end of the cylindrical container 51A. 7 is fixed by an adhesive or a means such as heat fusion and closed to form a bag-like container 51B for each paper box 1 as shown in FIG. 7 and retain the slack of the cylindrical container 51A. By attaching one surface to the top plate 5 with an adhesive to the inside surface of the top plate 5 except for the handles 45 and 46, a cylindrical housing portion 51 made of two flexible sheet materials is formed on the inside surface of the top plate 5. On the other hand, by attaching one surface of the bag-shaped container 51B that does not have slack to the inner surface of the top plate 5 except for the handles 45 and 46, two sheets are attached to the inner surface of the top plate 5. The bag-shaped storage portion made of the flexible sheet material can be formed. Then, a transparent or translucent plastic film tape is used as the narrow indefinite length tape-shaped flexible sheet material, and a nonwoven fabric tape is used as the wide indefinite length tape-shaped flexible sheet material. By doing so, the square-shaped plastic films 52a, 52b forming one surface of the cylindrical or bag-shaped container 51A, 51B that does not have any slack are formed on the upper sheet portion 52 of the cylindrical or bag-shaped container 51. In addition, square-shaped nonwoven fabrics 53a and 53b forming slackness of the cylindrical or bag-shaped storage bodies 51A and 51B and forming the other surface correspond to the lower surface sheet portion 53 of the cylindrical or bag-shaped storage portion 51. In addition, all of the above-described functions and effects of the cylindrical or bag-shaped storage portion 51 can be obtained.

[Effect of the invention]

 As is apparent from the above embodiment, the cold storage body accommodating structure in the paper box according to the present invention is a flexible sheet material provided in the paper box 1 provided with the handle 45, 46 for carrying formed by partially cutting and raising the top plate 5. A cylindrical or bag-shaped housing portion 51 made of the following is formed on the inner surface of the top plate 5, the cut-and-raised holes 45 a and 46 a of the handles 45 and 46 are closed by the housing portion 51, and the ceiling portion in the paper box 1 is formed. Since the cold insulator 50 is accommodated and held, the air in the ceiling portion in the paper box 1 is cooled by the cold insulator 50 and the cool air is lowered from the ceiling portion in the paper box 1. A shower effect can be obtained, and the inside of the paper box 1 can be cooled as it cools from corner to corner and from bottom to top. Thereby, there is an effect that it is possible to efficiently keep the cold object 49 in the paper box 1 cool.

The housing portion 51 has a rectangular shape for attaching one surface to the inner surface of the top plate 5 except for the handles 45 and 46 to close the cut-and-raised holes 45 a and 46 a of the handles 45 and 46. The upper sheet portion 52 (52a, 52b) and a predetermined edge facing the other surface of the upper sheet portion 52 (52a, 52b) which are overlapped and fixed to each other are fixed to form a cylinder. And a lower sheet 53 (53a, 53b), and a lower sheet 53 (53a, 53b). Since the cold insulator 50 is accommodated and held in between, the cut-and-raised holes 45a, 46a of the handles 45, 46 in the paper box 1 provided with the handle 45, 46 for the handbag formed by partially cutting and raising the top plate 5 are closed. , The heavens in paper box 1 This has the effect of appropriately obtaining the storage portion 51 which also serves to store and hold the cool insulator 50 in the well portion.

Further, since at least the upper sheet portion 52 (52 a, 52 b) is formed of a transparent or translucent plastic film, the inside of the housing portion 51 is formed by the cut-and-raised holes 45 a, 46 a of the handles 45, 46 from the outside of the paper box 1. Through this, it is possible to confirm whether or not the cold insulator 50 has been stored in the storage section 51, and to prevent the cold insulator 50 from being forgotten.
