Abstract: Disclosed is a receptacle with a lid. When the lid is press-fitted into a receptacle body, the packing that which protrudes outward from a rim section of the lid moves down along an inner wall of a receptacle body while varying internal pressure of the receptacle, thereby preventing the lid from being unintentionally separated from the receptacle body. The packing installed at the rim of the lid is integrally formed with the lid through an insert molding process. In a conventional lid structure, a packing having a wing section protrudes from a rim of the lid in a state in which the wing section is spaced apart from the lid, so that an additional coupling device is necessary to couple the packing to the lid. Due to the coupling device, productivity is lowered and quality of the product deteriorates.

Abstract: A thin packing cover needs some pressing and bending process to stick the packing material into the main cover. This inventory is the packing cover which can be manufactured without bending or pressing the main cover by the processing of double injection molding method that can inject the packing plastic material from upper and under packing place of the main cover.
