Although it is configured so as to be adjacent to each other via 241 and 251, the expanded and folded portions A and A ′ and B and B ′ may be configured with a space therebetween. However, the expanded and folded portions A, A ′ and B, B ′ are formed so as to be adjacent to each other via the substantially H-shaped cut lines 241 and 251 (see FIG. 2) and the substantially H-shaped cut lines 241 and 251. The connection cut lines 241b and 251b (see FIG. 2) formed in a circular arc shape that is convex on the upper edge side of the cylindrical paper body 2 include the expanded and folded portions A, A ′ and B, B ′. As an operation when folding inward with the left and right fingers, the left and right index fingers or the like support the engaging protrusions 21 located on both side edges of the cylindrical paper body 2 of the dripper 1 shown in FIG. In order to fold the expanded folds A, A ′ and B, B ′ with the thumb of the fold, the expanded folds A, A ′ and B, B ′ can be folded with one action (one operation) in a direction away from each other without any problem. 1 but on both side edges of the cylindrical paper body 2 of the dripper 1 shown in FIG. When the edge is supported by the left and right thumbs, etc., the expansion and folding parts A, A ′ and B and B ′ are folded in order to fold the expanding and folding parts A, A ′ and B and B ′ with the left and right index fingers or the like. In some cases, the expanding and folding portions A ′ and B ′ positioned below the substantially H-shaped cut lines 241 and 251 (see FIG. 2) cannot be folded in one operation, and the expanding and folding portions A and A ′ and The substantially H-shaped cut lines 241 and 251 of the expanded and folded portions A, A ′ and B and B ′ so that B and B ′ can be reliably folded in a direction away from each other (see FIG. 2). This is because the expanded and folded portions A ′ and B ′ positioned on the lower side are positioned on the upper end edge (on FIG. 2) side of the cylindrical paper body 2. In addition, as shown in FIGS. 1 and 2, when the expanded and folded portions A, A ′ and B, B ′ are adjacent to each other via the substantially H-shaped cut lines 241 and 251 (see FIG. 2). As a shape in which a connecting portion (blade stopper) is partially formed on the substantially H-shaped cut lines 241 and 251 (see FIG. 2), it can be more reliably folded inward with one action (one operation). It may be configured as follows.
[0026]
By the way, the drippers 1 and 1 ′ described so far are examples of the present invention and are not limited thereto. For example, the number and shape of the engagement protrusions 21 provided on the lower edge of the dripper 1 are as follows. The protrusion flaps 20 and 20 ′ are not necessarily required to have the same shape, and the protrusion width and the protrusion height may be changed.
