HOT-KEEPING CONTAINER MADE OF EXPANDED RESIN HAVING SKIN LAYER, AND MANUFACTURING METHOD FOR EXPANDED RESIN MOLDED ARTICLE FOR HOT-KEEPING CONTAINER

摘要

PROBLEM TO BE SOLVED: To provide a hot-keeping container made of an expanded resin having skin layers wherein a hot-keeping function for respective compartments is high and at the same time, to provide a manufacturing method for an expanded resin molded article for the hot-keeping container which forms a connected part of the internal and external skin layers in a manner to be superposed with each other.;SOLUTION: This hot-keeping container A is constituted of a set comprising a container main body 10 and a lid body 20 which are made of the expanded resin molded articles having the skin layers. In this case, on the surface of the expanded resin molded article which becomes a core layer C, a skin layer (a) on the internal surface side and a skin layer (b) on the external surface side are laminated. For the container main body 10 and the lid body 20, the internal surface side skin layer (a) protrudes to the external side wall surface part by exceeding the upper edge of the core layer C, and the internal surface side skin layer (a) is integrally bonded to the external surface side skin layer (b) under the superposed S state at the external side wall surface part of the core layer C. In addition, the hot-keeping container is divided into a plurality of compartments (d), and the container main body and the lid body are fitted each other in such a manner that respective compartments (d) can be kept under a respectively independent hot-keeping state while being isolated from other compartments for the hot-keeping container made of the expanded resin having the skin layers.;COPYRIGHT: (C)2004,JPO
