Abstract

PURPOSE:To inexpensively manufacture a resin vessel whose visual confirmation effect of contents is high, by a method wherein after a vessel body and lid body having a flange part at least on one side of each of them are molded separately on each of an opaque resin sheet material and transparent resin sheet, both the flange parts are heated and fused under a state they are piled up each other. CONSTITUTION:A sheet material 1A is an opaque thing obtained by cutting consumed and collected resin product into pieces and reclaiming the same and a sheet material 2A is a transparent thing made of an entirely fresh material. A vessel body 1 and a lid body 2 having flange parts 1F, 2F on the whole circumferential side are molded separately by applying vacuum molding to both the sheet materials. Then the flange parts 1F, 2F are piled up each other, fused by heating and an extremely thin part 3 becoming a folding part for a rocking, opening and closing fulcrum is formed. The lid body 2 obtained is transparent and a visual confirmation effect of contents under a packed state can be fulfilled reliably.

るものである。In order to achieve the above object, the method for producing a sheet-made resin container with a lid according to the present invention is to provide a container having a flange portion on at least one side, using an opaque υ (Jffi sheet material and a zo transparent resin sheet material). After molding the main body and the lid separately, the flange of the container main body and the flange of the lid are heat-welded in a polymerized state, and at this time, at or near the polymerized welded part, the container body and the lid are bonded together.

る。According to the manufacturing method according to the present invention having the above-mentioned characteristics, a completely new transparent resin material is used for forming the lid (since the M resin sheet material is required to have a visual effect on the contents). Although it is necessary to use a sheet material, recycled materials can be used as the resin sheet material for molding the container body, which is molded separately, since it can be opaque. Then, after forming the container body and the lid, an extremely thin part is formed at the same time during heat welding in the overlapping state of the flange part to unite them, and this can be used as a bent part for the swinging opening/closing fulcrum. In terms of process, only two steps are required: separate molding (simultaneous molding is possible) and heat welding.
