Description

  The present invention relates to a cold insulation case for keeping an article such as a food product cold by superimposing a box-shaped lid on a box-shaped storage body.

  2. Description of the Related Art Conventionally, food products that are preferably stored at a constant temperature have been transported while being kept cold by being covered with a heat insulating cold insulation cover when transported in a factory or delivered to a store.

  FIG. 8 is a diagram illustrating a state of use of a general cold insulation cover, and shows a state inside the cold insulation cover.

  When the food product or the like is kept cold using the cold insulation cover, as shown in FIG. 8, a bag is placed on the frame material 321 standing on the cart 320 with the article 330 such as the food product placed on the cart 320. Alternatively, a box-shaped cool cover 310 is hung. Since the cold insulation cover 310 has a heat insulating property, the article 330 is cooled by preliminarily cooling the article 330 to a predetermined temperature, or by placing a frozen cold insulation agent on the carriage 320 together with the article 330. However, it is hardly affected by the temperature of the outside air, and is kept at a constant temperature.

  In this way, a technique for keeping food items etc. at a constant temperature by covering them with a heat insulating cold insulation cover in a state where food items etc. to be kept cold are placed on a cart or the like is considered ( For example, see Patent Document 1).

Japanese Utility Model Publication No. Hei 6-27423.

  However, in the case shown in FIG. 8, a gap is formed in the lower part of the cold insulation cover 310 in a state where the article 330 is covered with the cold insulation cover 310, and warm air enters the inside of the cold insulation cover 310 from the gap, and the article 330. May be warmed.

  Further, when the height of the article 330 placed on the carriage 320 is lower than the height of the frame member 321, a space 340 is generated on the article 330, but the temperature of the air existing in the space 340 is affected by the outside air. If it rises, the article 330 will be warmed.

  The present invention has been made in view of the problems of the conventional techniques as described above, and provides a cold insulation case having a structure in which an article is difficult to be warmed in a cold insulation case for conveying the article while keeping the article cold. The purpose is to do.

In order to achieve the above object, the present invention provides:
A box-shaped storage body having a top surface as a first opening, and a bottom surface serving as a second opening, and the storage body from the second opening so as to cover the first opening. In a cold insulation case having a box-shaped lid that covers the first opening,
The storage body has a first protrusion that continues to the outer surface along the first opening,
The lid body has a second protrusion that continues along the second opening on the inner surface.

  In the present invention configured as described above, in a state where the article is stored in the storage body, the storage body is covered with the storage body from the second opening of the cover body so as to cover the first opening of the storage body. By entering the inside, the article is surrounded by the storage body and the lid, and is conveyed while being kept cold. At this time, at least part of the side surfaces of the storage body and the lid body overlap each other so that the side surface of the lid body is on the outside, but along the first opening on the outer side surface of the storage body The first protrusions that are continuous are provided, and the second protrusions that are continuous along the second opening are provided on the inner side surface of the lid, so that the side surfaces of the storage body and the lid overlap each other. Even if there is a gap between the outer side surface of the storage body and the inner side surface of the lid in the portion, the first protrusions and the second protrusions are alternately arranged, thereby Warm air is less likely to enter the interior of the cold insulation case, and articles stored in the storage body are less likely to be warmed. Further, a space is created on the article when the height of the article stored in the storage body is higher than the height of the storage body. At least a part of the side surface facing the space and the lid Since it has a double structure in which the side of the body overlaps, the temperature of the air existing in the space becomes less susceptible to the influence of outside air, which also makes it difficult to warm the article.

  Further, if at least one of the first and second protrusions has flexibility, the height of the first and second protrusions is increased so that warm air outside can enter the inside of the cold insulation case. If the first protrusion and the second protrusion come into contact with each other when the storage body is inserted into the lid when it is further difficult to enter, the first protrusion and the second protrusion are bent. Therefore, it is not difficult for the storage body to enter the lid.

  According to the present invention, the first protrusion that continues along the first opening is provided on the outer surface of the storage body, and the second that continues along the second opening on the inner surface of the lid. In the state where the article is stored in the cold insulation case, there is a gap between the outer surface of the storage body and the inner surface of the cover body in the overlapping portion of the storage body and the side surface of the cover body. Even if it occurs, the first protrusions and the second protrusions are alternately arranged, so that it is difficult for outside warm air to enter the inside of the cold insulation case, and the article stored in the storage body Can be made difficult to warm. Further, although a space is created on the article when the height of the article stored in the storage body is higher than the height of the storage body, at least a part of the side surface and the lid of the storage body is formed on the side surface portion facing the space. Since it has a double structure in which the side of the body overlaps, the temperature of the air existing in the space becomes less susceptible to the influence of outside air, and the article can also be made difficult to warm.

  In addition, when at least one of the first and second protrusions has flexibility, the height of the first and second protrusions is increased so that warm air outside can further enter the inside of the cold insulation case. When it is difficult to enter, the first protrusion and the second protrusion are bent even when the first protrusion and the second protrusion are brought into contact with each other when the storage body is inserted into the lid. , It will not be difficult for the storage body to enter the lid.

  Below, the usage method of the cover body 10 and the storage body 20 which were comprised as mentioned above is demonstrated.

  3A and 3B are diagrams showing a use state of the cold insulation case constituted by the lid body 10 shown in FIG. 1 and the storage body 20 shown in FIG. 2, wherein FIG. 3A is an external perspective view, and FIG. It is AA 'sectional drawing shown to a). FIG. 4 is a view for explaining a method of storing articles in the cold insulation case shown in FIG. 3 and shows an internal state of the cold insulation case.

  As shown in FIG. 3, the cold insulation case of the present invention is configured by overlapping the lid body 10 shown in FIG. 1 and the storage body 20 shown in FIG. 2, and the article 30 is stored inside and used. . In addition, it is good also as a structure which can be conveyed, without lifting a cold storage case by attaching a caster (not shown) to the bottom face 21 of the storage body 20. FIG.

  When an article such as a food product is stored in a cold insulation case constituted by the lid 10 shown in FIG. 1 and the storage body 20 shown in FIG. 2, first, as shown in FIG. The article 30 cooled to the above temperature is stored in the storage body 20.

  Next, the storage body 20 is made to enter the inside of the lid body 10 through the opening portion 14 of the lid body 10 so as to cover the opening portion 24 of the storage body 20. At this time, as described above, the opening 24 of the storage body 20 has a slightly smaller shape than the opening 14 of the lid body 10, so that the inner surfaces of the side surfaces 12 a to 12 d of the lid body 10 A gap of several millimeters is formed between the outer surfaces of the side surfaces 22a to 22d of the storage body 20. Then, as the storage body 20 enters the inside of the lid body 10, the projections 13 provided on the side surfaces 12 a to 12 d of the lid body 10 and the projection parts 23 provided on the side surfaces 22 a to 22 d of the storage body 20. As described above, since the protrusions 12a to 12d and 22a to 22d are made of a material having flexibility such as cloth, as shown in FIG. Thus, the protruding protrusions 13 and 23 are not bent, and the housing body 20 does not easily enter the lid body 10.

  When the height of the article 30 stored in the storage body 20 is higher than the height of the storage body 20, the upper surface of the article 30 is inside the top surface 11 of the lid body 10 as shown in FIG. The article 30 is stored in the cold insulation case in a state surrounded by the storage body 20 and the lid body 10.

  Below, the effect by the cold storage case mentioned above is demonstrated.

  FIG. 5 is a view for explaining the effect of the cold insulation case constituted by the lid body 10 shown in FIG. 1 and the storage body 20 shown in FIG. 2, and shows the internal state of the cold insulation case.

  When the height of the article 30 stored in the cold insulation case constituted by the lid 10 shown in FIG. 1 and the storage body 20 shown in FIG. 2 is higher than the height of the storage body 20, FIG. As shown in the figure, the upper surface of the article 30 comes into contact with the inner surface of the top surface 11 of the lid 10, and the article 30 is stored in the cold insulation case in a state surrounded by the storage body 20 and the lid 10. . At that time, the side surfaces 22a to 22d of the storage body 20 and the side surfaces 12a to 12d of the lid body 10 are partly overlapped with each other so that the side surfaces 12a to 12d of the lid body 10 are outside. On the outer surfaces of the side surfaces 22 a to 22 d of the body 20, there are provided protrusions 23 that continue along the opening 24 of the storage body 20, and on the inner surfaces of the side surfaces 12 a to 12 d of the lid body 10, Since the protruding portion 13 is provided along the opening 14 of the lid body 10, the side surface 22 a of the storage body 20 is overlapped with the side surfaces 22 a to 22 d of the storage body 20 and the side surfaces 12 a to 12 d of the lid body 10. Even if there is a gap between the outer surface of ˜22d and the inner surface of the side surfaces 12a to 12d of the lid 10, as shown in FIG. These protrusions can get into It would be prevented by 3, 23.

  At this time, the heights of the protrusions 13 and 23 are lower than the gaps formed between the inner surfaces of the side surfaces 12a to 12d of the lid body 10 and the outer surfaces of the side surfaces 22a to 22d of the storage body 20, respectively. Even if it is a thing, in the clearance gap which arose between the inner surface of the side surfaces 12a-12d of the cover body 10, and the outer surface of the side surfaces 22a-22d of the storage body 20, the protrusion part 13 and the protrusion part 23 exist. It becomes the state arrange | positioned alternately, and it becomes difficult for the warm air of the outside to enter the inside of a cold insulation case, and can make it difficult to warm the articles | goods accommodated in the storage body 20. FIG. In that case, if the heights of the protrusions 13 and 23 do not come into contact with each other when the storage body 20 enters the inside of the lid body 10 as described above, the protrusions 13 and 23 are flexible. It is not necessary to make it from the material which has property. Further, when the protrusions 13 and 23 are made of a material having no flexibility, the height of the protrusions 13 and 23 is slightly affected when the storage body 20 enters the inside of the lid body 10. Even if it contacts, the storage body 20 can enter the inside of the cover body 10 by bending the cover body 10 or the storage body 20.

  Further, the heights of the protrusions 13 and 23 fill the gaps formed between the inner surfaces of the side surfaces 12a to 12d of the lid body 10 and the outer surfaces of the side surfaces 22a to 22d of the storage body 20, respectively. If sufficient, the protrusion 13 abuts against the outer surfaces of the side surfaces 22a to 22d of the storage body 20 to prevent outside warm air from entering the inside of the cold insulation case, and the protrusion 23 abuts on the inner surfaces of the side surfaces 12a to 12d of the lid body 10, so that the cool air in the cold insulation case is prevented from flowing out, and the articles stored in the storage body 20 are further prevented from being warmed. Can do. In that case, the height of either one of the protrusions 13 and 23 is a gap generated between the inner surface of the side surfaces 12a to 12d of the lid body 10 and the outer surface of the side surfaces 22a to 22d of the storage body 20. If it is sufficient to fill the space, the air flow between the inside and outside of the cold insulation case is blocked and the above effect can be obtained. As long as it is sufficient to fill a gap formed between the inner surfaces of the side surfaces 12a to 12d of the body 10 and the outer surfaces of the side surfaces 22a to 22d of the storage body 20, the protruding portions 13 and the protruding portions 23 are used. A space surrounded by the inner surfaces of the side surfaces 12 a to 12 d of the lid body 10, the outer surfaces of the side surfaces 22 a to 22 d of the storage body 20, and the protrusions 13 and 23 is formed. , There is no direct inflow / outflow of air inside and outside the cool case Ri, can be further enhanced the effect.

  When the height of the article 30 stored in the cold insulation case is higher than the height of the storage body 20, as shown in FIG. 5B, a space 40 is generated on the article 30, but faces the space 40. Since the side surface has a double structure in which the side surfaces 22a to 22d of the storage body 20 and the side surfaces 12a to 12d of the lid body 10 overlap each other, the temperature of the air existing in the space 40 is hardly affected by the outside air. This also makes it difficult for the article 30 to be warmed. In this embodiment, since the height of the storage body 20 and the height of the lid body 10 are the same, the side surfaces 22a to 22a of the storage body 20 are formed on the entire side surface portion facing the space 40 generated on the article 30. 22d and the side surfaces 12a to 12d of the lid body 10 have a double structure, but when the height of the lid body 10 is lower than the height of the storage body 20, the space 40 formed on the article 30 faces the space 40. The side surface portion 22a to 22d of the storage body 20 and the side surface 12a to 12d of the lid body 10 are overlapped only in a part of the side surface portion to be overlapped. However, it is possible to obtain an effect that the article 30 is hardly warmed.

  Further, as described above, since the protrusions 13 and 23 are each U-shaped, and thus have an air layer inside, this air layer is also interposed between the outside and the article 30, and this air Even with the layer, a cold insulation effect in the cold insulation case can be obtained.

  Below, the taking-out method of the articles | goods 30 accommodated in the cold storage case is demonstrated.

  FIG. 6 is an external perspective view for explaining a method of taking out the article 30 stored in the cold insulation case constituted by the lid 10 shown in FIG. 1 and the storage body 20 shown in FIG.

  When the article 30 stored in the cold insulation case is taken out as described above, as shown in FIG. 6, in the lid body 10, the hooked surface fastener 15a and the hooked surface fastener 15b are peeled off, and the side surface 12a is removed. The connecting side with the top surface 11 is spread out as a fulcrum, and in the storage body 20, the hooked surface fastener 25a and the surface fastener 25b are peeled off, and the side surface 22a is spread out with the connecting side with the bottom surface 21 as a fulcrum.

  Then, one side surface of the cold insulation case is opened, and the article 30 can be taken out from the opened portion.

  In addition, as above-mentioned, the protrusions 13 and 23 provided in the cover body 10 and the storage body 20 are cross sections in the direction orthogonal to the direction which continues along the opening parts 14 and 24, and the side surfaces 12a-12d and 22a-22d. It is U-shaped open to the side, and is not limited to one in which both ends of the U-shape are fixed to the side surfaces 12a to 12d and 22a to 22d by sewing or the like.

  FIG. 7 is a view showing another form of the protrusion provided on the lid or the housing, and shows a cross-sectional view of the vicinity of the protrusion.

  As shown in FIG. 7A, the protrusion provided in the lid or the housing has an O-shaped cross section in a direction orthogonal to the direction in which the protrusions 113 and 123 are continuous. A portion extending from one point in contact with the side surface may be fixed to the side surface by sewing or the like. Even in such a configuration, since the air layer is provided inside the O-shape, the air layer is also interposed between the outside and the article 30, and the air insulation effect in the cold insulation case is also provided by the air layer. Can be obtained.

  Moreover, as shown in FIG.7 (b), a T-shaped thing may be sufficient. In the case of the T shape, the T-shaped horizontal bar portion is fixed to the side surface by sewing or the like, and the T-shaped vertical bar portion plays a role of blocking outside air.

  In addition, the protrusion part which has an air layer in the inside like the above-mentioned U shape or O shape, and the protrusion part which does not have an air layer inside like a T shape can also be combined. If at least one of them has an air layer, the air-cooling effect in the heat-retaining case can be obtained also by the air layer.

  In addition, the protrusions are not limited to those having flexibility such as cloth and rubber, but at least one of the protrusions provided on the lid and the protrusions provided on the storage body has flexibility. Thus, when the storage body enters the lid, even if these two protrusions come into contact with each other, the flexible one of the two protrusions bends, making it difficult for the storage body to enter the lid. It will not be.
