[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper tray made of paper or the like which is easy to assemble and has a high strength for supporting inclusions.

[0002]

2. Description of the Related Art Conventionally, various trays and carry-deco cases have been used to carry Western confectionery and the like. Most of these trays and carry deco cases are made of paper or the like, and are folded and stored until used, and can be quickly and easily assembled at the time of use.

[0003]

However, such trays and the like are made of paper or the like as described above, are often very simple in structure, and cannot be said to be strong in terms of strength. In other words, no matter how light the weight of the confectionery that is carried in the container, when it contains a large number of cakes, or when it is decorated cake before being cut, it has enough weight. There was a case where a large load was applied to the base and the bottom might come off. Also, in the above carry deco case, when taking out the cake etc. inside,
Open the top plate of the case and take it out, or at most open the top plate and one side of the case and take it out, but the distance between the inner surface of the case and the enclosed cake is narrow, so take out without touching the cake Was sometimes difficult.

Therefore, the present invention provides a paper tray which is easy to assemble and has a simple structure, is made of paper or the like, is strong against the load applied to the bottom, and is extremely easy to take out cakes and the like. This is to solve the above-mentioned problem.

According to a first aspect of the present invention, a substantially fan-shaped side plate is provided on each side edge of the polygonal insole through a fold, and the center of the fold of each side edge is provided. Each of the portions is provided with a notch of a substantially convex shape from the fold toward the substantially central portion of the midsole, and a plate having substantially the same shape as the side plate is annularly connected by the number of side edges of the midsole to form a substantially bottomless portion. A mortar-shaped outer frame is formed, each side plate of the middle bottom is erected with the fold as a boundary, and the respective cut portions of the middle bottom are respectively hung down with the fold as a boundary, and the middle bottom is formed with the outer bottom. At the position where the midsole is supported by the side plates of the midsole on each plate body of the outer frame, the position of the lower end edge of each of the downwardly projecting leg portions and the outer frame Is a paper tray having a configuration in which the position of the lower end edge of the paper tray substantially matches.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A paper tray according to a first embodiment of the present invention will be described below with reference to the drawings. First, FIG.
FIG. 3 is a development view of the midsole A of this paper tray made of a cardboard material having a small thickness. The midsole A is provided with a regular hexagonal bottom surface 1 and folds 2 on each side edge around the bottom surface 1. The fold 2 which is provided and has a curved upper side 3a and a lower side is composed of six substantially fan-shaped side plates 3 which are shorter than the upper side 3a. Also, from the fold 2 toward the center of the bottom surface 1 at the center of the fold 2 at each side edge,
Six notches 4 each having a convex shape are provided.

FIG. 4 is an exploded view of an outer frame B of the paper tray. The outer frame B is formed by connecting six plate members 5 laterally through a fold 5a. A glue margin 5b is provided at one edge to connect the bodies 5 in a ring shape. The shape of each plate 5 is substantially the same as that of the side plate 3 of the midsole A, and the upper side 5c is longer and the lower side 5d is shorter, and is substantially fan-shaped. . Further, when compared with the individual side plates 3 of the midsole A, the individual plate members 5 are slightly longer in the vertical direction and slightly shorter in the horizontal direction. The material is the same as that of the side plate 3 of the midsole A.

Next, the paper tray is assembled. First, as shown in FIG. 5, the six plate members 5 of the outer frame B are sequentially folded in accordance with the respective folds 5a, and the margin 5b at the edge is glued and fixed to the back side of the plate member 5 at the other edge. Thus, the continuous plate body 5 becomes a substantially mortar-shaped outer frame B having no top surface and bottom surface.

Then, as shown in FIG. 6, each side plate 3 of the insole A is bent by the crease 2 to form the insole A in a concave shape. At this time, according to the shape of the six side plates 3,
The shape of the midsole A is a shape obtained by inverting a hexagonal pyramid without a bottom surface. In addition, due to the respective sizes of the plate 5 and the side plates 3, the length of the inclined side surface of the outer frame B is longer than the length in the same direction of the inner bottom A on which the six side plates 3 are erected. On the other hand, from the size of the circular opening on the bottom surface of the outer frame B,
The size of the bottom of is slightly larger.

As shown in FIGS. 1 and 7, the protruding leg portions 4a formed by the cuts 4 provided from the respective folds 2 on the side edges of the insole A are projected downward from the folds 2 respectively. In this state, as shown in FIGS. 1 and 2, the midsole A is fitted into the annularly connected outer frame B from above. The positions where the six side plates 3 of the insole A are in contact with the respective plate members 5 on the inner peripheral surface of the outer frame B and the insole A is supported by the outer frame B are simultaneously projected downward from the respective protruding leg portions. The position of the lower edge of the portion 4a coincides with the position of the lower edge of each plate 5 of the outer frame B, and these have reached the surface of a table (not shown) on which the paper tray is placed. The paper tray is supported on a table by the lower edge of the projecting leg 4a and the lower edge of each plate of the outer frame B.

Next, a second embodiment will be described with reference to the drawings. FIG. 8 shows that the basic configuration of the second embodiment is almost the same as that of the first embodiment. In the second embodiment, each side plate 6 of the insole C
Is not a curve in which the upper side 6a is bulged, but the bulged portion is cut off. When such an insole C is fitted into the outer frame D and the insole C is supported by the outer frame D, the bulging portion of the upper side 7a of each of the plate members 7 forming the outer frame D is moved to the center. The upper side 6a of the side plate 6 of the bottom C is creased and folded inward. Thereby, the midsole C is firmly supported by the outer frame D. Then, a cover (not shown) formed slightly larger than the shape of the opening on the upper surface of the outer frame D is put on the paper frame from above.

As described above, when the cake placed in the paper tray according to the first embodiment or the paper box according to the second embodiment is carried out, in either case, the side plates 3 of the insole A or C, 6. Pick up the appropriate upper sides 3a, 6a at two places, lift from the outer frame B or D, and place it again in another place, the side plates 3, 6 of the insole A, C will naturally be 360 degrees omnidirectional The cake can be easily cut or transferred to another dish without breaking the shape of the cake because there is no obstruction. Also, the cuts on the bottom of the bottoms A and C are
Each of the holes is a hole. For example, when these opposing holes are connected to each other above a paper tray or the like through a ribbon or the like from below, decoratively beautiful.

In the above embodiment, the insole A, C
Is a regular hexagonal shape, but the shape of the insole A, C is not limited to this, and may be any polygonal shape such as a quadrangle or an octagon, and even if it is not a regular polygonal shape, It may be simply a polygonal shape. Furthermore, although the size of the side plate 3 of the midsole A and the size of the plate 5 of the outer frame B are specifically described, these are not essential requirements of the present invention, and the height of the plate 5 of the outer frame B is not limited thereto. The height is higher than that of the side plate 3 of the midsole A. However, the height of the side plate 3 of the midsole A is increased by reversing the height, and two holes are drilled there. It may be a hole for inserting a finger. Although a thin cardboard material is used as the material, the present invention is not limited to this, and a thick cardboard material may be used as long as the effects of the present invention can be achieved. What stuck wrapping paper, colored paper, etc. may be used.

[0014]

According to the paper tray of the first aspect of the present invention, since the inner bottom is merely fitted into the outer frame, it can be produced very easily. Further, since the midsole is supported not only by the lower end edge of the outer frame but also by a protruding piece leg projecting downward from the midsole, the strength against the inclusions is high and the bottom does not come off. Further, when taking out the included western confectionery or the like, if the inner bottom is removed from the outer frame, the side plate of the inner bottom opens at 360 degrees, so that the cake or the like can be taken out very easily without breaking its shape.
