Claims

[Claims for Utility Model Registration] 1. Three sheet pieces, the first sheet piece 1a, the second sheet piece 1b, and the third sheet piece 1c, have a fold line 4a.
, 4b to form a postcard main body 1, and an address and address display section 2 are formed on one side of the first sheet piece 1a, and a second sheet piece 1b and/or a third sheet. A display section 3 for displaying information etc. is formed on one side of the piece 1c, and the postcard main body 1 has the second sheet piece 1b and the third sheet piece 1.
It is formed into a substantially Z-shaped three-fold state so that the display surfaces of information, etc., face each other, and the third
A synthetic resin layer 5 is provided on the display surface side of the second sheet piece 1b and the third sheet piece 1c facing each other in the folded state.
, 5, a synthetic resin film 6, which can be torn through the film 6,
6 is pasted, and both sheet pieces 1b
, 1c facing each other are thermally bonded in a peelable manner, and furthermore, the sheet piece 1a and the sheet piece 1b in the trifold state are thermally bonded in a non-peelable manner. 2 Three sheet pieces, the first sheet piece 1a, the second sheet piece 1b, and the third sheet piece 1c, have a fold line 4a.
, 4b to form a postcard main body 1, and an address and address display section 2 are formed on one side of the first sheet piece 1a, and a second sheet piece 1b and/or a third sheet. A display section 3 for displaying information etc. is formed on one side of the piece 1c, and the postcard main body 1 has the second sheet piece 1b and the third sheet piece 1.
It is formed into a substantially Z-shaped three-fold state so that the display surfaces of information, etc., face each other, and the third
