The width of tip portion 53b in first direction DR1 is greater than the width of tip portion 43b in first direction DR1. Therefore, the fourth bottom panel 53 does not have the same shape as the third bottom panel 43 .

The blank 100 is transported in the state shown in FIG. (described later).

<Construction of Container Main Body 200>
The configuration of the container body 200 will be described below.

The container body 200 is formed by assembling the blank 100 . FIG. 3 is a plan view of the container body 200. FIG. 4 is a bottom view of the container body 200. FIG. As shown in FIGS. 3 and 4, container body 200 has recess 210 . The recessed portion 210 is an internal space of the container body 200 defined by a side surface 211 and a bottom surface 212 .

The first bottom panel 22 and the second bottom panel 32 do not overlap each other. The third bottom panel 43 and the fourth bottom panel 53 overlap each other. More specifically, the tip 43b and the tip 53b overlap each other.

<Configuration of container 300>
The configuration of the container 300 will be described below.

The container 300 is, for example, a food container. However, the application of the container 300 is not limited to this. FIG. 5 is an exploded perspective view of the container 300. FIG. As shown in FIG. 5, container 300 has container body 200 and liner 310 . The liner 310 is film-like. The liner 310 is made of a resin material. The liner 310 is made of, for example, a thermoplastic resin material.

The liner 310 may be a multilayer film. FIG. 6 is a perspective view of a multilayer film as liner 310. FIG. As shown in FIG. 6, the liner 310 has an intermediate layer 310a, a base layer 310b and an adhesive layer 310c. The intermediate layer 310a is preferably made of a gas barrier resin material. The intermediate layer 310a is made of, for example, an ethylene-vinyl alcohol copolymer (EVOH) resin material. The intermediate layer 310a is sandwiched between the base layers 310b with the adhesive layer 310c interposed therebetween.

The liner 310 covers the side surface 211 and the bottom surface 212 from the inside of the container body 200 and also covers the surface of the flange portion 10 . Liner 310 is preferably peelable from container body 200 . Although not shown, a lid may be attached to the flange portion 10 via the liner 310 .

<Manufacturing Method of Container 300>
A method for manufacturing the container 300 will be described below.

FIG. 7 is a process diagram showing a method for manufacturing the container 300. FIG. As shown in FIG. 7, the method for manufacturing the container 300 includes a container body assembling step S1 and a liner attaching step S2.

In the container body assembly step S1, the container body 200 is assembled from the blank 100. This assembly is performed, for example, by inserting a plunger matching the shape of the recess 210 from the opening 13 . At this time, the first bottom panel 22 and the second bottom panel 32 are cut along the perforations PF.

In the liner attaching step S2, the liner 310 is attached to the container body 200. The liner attaching step S2 is performed by placing the liner 310 softened by heating on the container body 200 which is being sucked from the outside. However, the method of attaching the liner 310 is not limited to this.

<Effect of blank 100>
The effect of the blank 100 will be described below in comparison with a blank according to a comparative example (“blank 100A”).

FIG. 8 is a developed view of the blank 100A. As shown in FIG. 8, the blank 100A has a flange portion 10, a first panel 20, a second panel 30, a third panel 40 and a fourth panel 50. As shown in FIG. In this regard, the configuration of blank 100A is in common with that of blank 100. FIG. In blank 100 A, first panel 20 does not have first bottom panel 22 and second panel 30 does not have second bottom panel 32 . In this regard, the configuration of blank 100A is in common with that of blank 100. FIG.

In the blank 100A, the first panel 20 does not have the first bottom panel 22 and the second panel 30 does not have the second bottom panel 32, as described above. Therefore, in the blank 100A, the first panel 20 and the second panel 30 are independent of each other. As a result, the first panel 20 and the second panel 30 may be damaged by being caught around during transportation or assembly.

On the other hand, in blank 100 , first panel 20 has first bottom panel 22 and second panel 30 has second bottom panel 32 . Also, the first bottom panel 22 and the second bottom panel 32 are connected to each other. Therefore, in the blank 100, the first panel 20 and the second panel 30 are fixed to each other, and are hard to be damaged during transportation or assembly. In addition, since the connection between the first bottom panel 22 and the second bottom panel 32 is easily cut by the perforations PF, it does not hinder assembly.

When assembling the container body 200 using the blank 100A, the first panel 20 does not have the first bottom panel 22 and the second panel 30 does not have the second bottom panel 32, so the bottom surface 212 is composed only of the third bottom panel 43 and the fourth bottom panel 53 . As a result, when the blank 100A is used to assemble the container body 200, the rigidity of the bottom surface 212 is low, and the liner 310 tends to peel off when an external force is applied to the bottom surface 212. FIG.

On the other hand, when assembling the container body 200 using the blank 100, since the first panel 20 has the first bottom panel 22 and the second panel 30 has the second bottom panel 32, The bottom surface 212 is composed of the first bottom panel 22 , the second bottom panel 32 , the third bottom panel 43 and the fourth bottom panel 53 . Therefore, when the container body 200 is assembled using the blank 100, the rigidity of the bottom surface 212 is increased compared to when the container body 200 is assembled using the blank 100A, and the liner 310 is peeled off even if an external force is applied to the bottom surface 212. difficult to do.

When the basis weight of the paper forming the blank 100 is small, the connection between the first bottom panel 22 and the second bottom panel 32 can be easily cut off during assembly, which improves the ease of assembly. However, in this case, there is a risk that the connection between the first bottom panel 22 and the second bottom panel 32 will be cut off during transportation. When the basis weight of the paper forming the blank 100 is large, it is difficult to disconnect the first bottom panel 22 and the second bottom panel 32 during transportation. However, in this case, since the connection between the first bottom panel 22 and the second bottom panel 32 is difficult to cut during assembly, there is a possibility that the ease of assembly may deteriorate.

When the blank 100 is formed of paperboard with a basis weight of 190 g/m ² or more and 400 g/m ² or less, the ease of disconnection between the first bottom panel 22 and the second bottom panel 32 during transportation is appropriately adjusted. can do. Therefore, in this case, it is possible to maintain ease of assembly while suppressing disconnection between the first bottom panel 22 and the second bottom panel 32 during transportation.
