<p><P>PROBLEM TO BE SOLVED: To provide a resin-made pallet capable of being used for a long period of time without separation on a mutual welded surface or a parting line even in the case that curved deformation distortion is generated by a load of a freight added to a hollow double wall structure constituting the pallet. <P>SOLUTION: The resin-made pallet 1 is obtained by blow-molding a thermoplastic resin. The hollow double wall structure 2 constituting the pallet has one wall or the upper surface wall 4 and the other wall or the lower surface wall 5, and both walls face each other with a clearance serving as a hollow part placed between them. The parting line 7 or the mutual welded surface of one half body and the other half body of the hollow double wall structure 2 is formed during blow molding. An outward protruding ridge 8 is formed along the parting line 7 to increase the welded surface area. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
