 The multipack 1 is formed by assembling the blank 2 shown in FIG. The blank 2 includes a top plate 12, side plates 14 and 15 connected to both sides of the top plate 12, a first bottom plate piece 16 a connected to the side plate 14, and a second bottom plate connected to the side plate 15. And a piece 16b. The blank 2 is a substantially rectangular flat plate having a longitudinal direction from the first bottom plate piece 16a to the second bottom plate piece 16b as a whole. An insertion port 24 is formed at the boundary (first bottom plate boundary) 28 between the side plate 14 and the first bottom plate piece 16a, and an insertion piece 26 is formed at the end of the second bottom plate piece 16b. The first top plate boundary 18, the second top plate boundary 19, the first bottom plate boundary 28, and the boundary (second bottom plate boundary) 29 between the second bottom plate piece 16b and the side plate 15 are all mountain fold lines. Has been.

 The blank 2 is manufactured, for example, by cutting a paper flat plate to form the main body 10 and sticking a resin film to the main body 10 so as to close the opening 20.

An example of a method for assembling the blank 2 and packaging the two articles 30 will be described.
First, the blank 2 is placed so that the top plate 12 is positioned on the top surface of the two to-be-packaged objects 30 arranged, and the first top plate boundary 18 and the The second top plate boundary 19 is made into a mountain fold. At this time, the package 30 is in a state in which a part of the top surface peripheral edge portion 32 protrudes in the width direction of the top plate 12.
Next, the first bottom plate boundary 28 and the second bottom plate boundary 29 are fold-folded, the first bottom plate boundary 28 and the second bottom plate boundary 29 are overlapped on the bottom surface of the package 30, and the insertion piece 26 is inserted. A bottom plate 16 (FIG. 1) is formed by inserting into the insertion opening 24, and a package body in which the package object 30 is packaged by the multi-pack 1 having a substantially rectangular tube shape is obtained.
The article 30 to be packaged packed in the multipack 1 is held in the vertical direction by the top plate 12 and the bottom plate 16 and held in the width direction by the side plates 14 and 15. In addition, the periphery of the opening 20 abuts on the top surface or the side surface of the object to be packaged 30, and the window body 40 abuts on the top surface peripheral part 32 and the side surface of the object to be packaged 30. It is held well in the multipack 1.
