Abstract

PURPOSE:To color the internal plane of the cover plate part of a binding member with a color different from that of a housing bowl by constituting one side of an internal piece for both bottom/ back continuation with the color same as that of an external plane piece and the other side of an internal plane piece for cover part with the color different from that of the external plane piece. CONSTITUTION:An inside member is obtained by connecting the entire edge of the outer periphery of a thick paper core plate 33 for bottom, black internal plane pieces 34, 35 for bottom/back part, and a brown internal plane piece 37 for cover part to film 32 for core. The inside member is superimposed on an outside member, and the back part of the inside member is welded, and the entire edge of the bottom part and cover part of the outside member and that of the inside member are sewn by a thread stripe. Thereby, a binding part plate in which a bottom plate part and a brown cover plate part are provided successively at both sides of the back plate part via a free folding part is obtained. Also, a black housing bowl for stationery is constituted by applying squeezing to a black thin plate of hard thermoplastic synthetic resin and providing a welding edge to the entire outer periphery of a double structure. A pen case main body is obtained by erecting the bowl horizontally on the back plate part of the binding member, and connecting by bringing down the black housing bowl, and interposing it on the bottom plate part of the binding member, then, applying pressurization/heating working.
