FIG. 3 is a plan view of a sheet material forming the holder. In these figures, the holder 10 is formed of an appropriate synthetic resin sheet material. The holder 10 includes a bottom edge 11, side edges 12 connected to both ends of the bottom edge 11, a lid forming piece 14 provided at a position facing the bottom edge 11, and a lid forming piece 14.
And a tongue piece 15 having a free end directed in a direction opposite to the bottom edge when the lid forming piece 14 is in the closed position, and a slit 16 into which the tongue piece 15 can be inserted. It is comprised including.

The bottom edge 11 is, as shown in FIG.
Three fold lines 11A, 11B, formed at lower positions slightly shifted from the longitudinal center line C of the sheet material S,
11C, it is formed by folding the central bending line 11B inward. Here, in FIG. 3, the area below the center line C is the front side sheet S shown in FIG.
1, while the upper region constitutes the back side sheet S1, and when folded along the folding lines 11A to 11C, is folded into two sheets.

A gusset 20 is connected to both left and right ends of the front sheet S1. Each outer edge of these gussets 20 is welded to the opposite edges of the back side sheet S2.
As shown in FIG. 2, the upper end side, which is opposite the bottom edge side, is formed in a bag shape that becomes the opening 21.

As shown in FIGS. 1 and 2, the upper end edges between the front sheet S1 and the back sheet S2 are formed as non-welded portions 23, and between the lower ends of the left and right non-welded portions 23 in FIG. , A straight folding line 25 is formed, whereby the front sheet S1 can be bent outward to open the opening 21 largely.

The sheet S2 on the back side has an initial length protruding upward longer than the upper end of the sheet S1 on the front side in a state where the sheet S2 is folded to a thickness of two sheets as described above, and one end region of the front end thereof has the front side. It is formed as a lid forming piece 14 folded on the sheet S1. Further, a welded portion 14A is provided along the folded line of the lid forming piece 14, and a folding habit is provided so that the lid forming piece 14 can always be in close contact with the front sheet S1 surface. As shown in FIGS. 1 and 2, one tongue piece 15 provided on the inner surface side of the lid forming piece 14 has a fixed end at the lower end, a free end at the tip, and Is pointed in the opposite direction.
At this time, in order to increase the strength on the fixed end side of the tongue piece 15, a welded portion 30 is formed along the lateral direction.

Slit 1 formed on front sheet S1
