Receptacle with lid integrally formed with packing having wing section

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. To solve this problem, a support wall is provided at a lower portion of the lid and a fixing member of a packing is fabricated through an insert molding process such that the fixing member closely adheres to the support wall. A wing section protrudes from the fixing member while being integrally formed with the fixing member, so that the packing is installed in the lid without using an additional coupling device.

Description

PRIORITY[0001]This application claims the benefit under 35 U.S.C. § 119(a) of a Korean patent application filed in the Korean Intellectual Property Office on Jul. 26, 2007 and assigned Serial No. 2007-75045, the entire disclosure of which is hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a packing, which is installed in a lid mounted on a receptacle used for storing foods, etc., and is fabricated through an injection molding by using plastic. More particularly, the present invention relates to a receptacle with a lid, in which a packing having a foldable wing section is integrally formed with the lid through a dual injection molding scheme, such as an insert molding scheme, so that, when the lid is press-fitted into a receptacle body, the wing section of the packing, which protrudes outward from a rim section of the lid, closely adheres to an inner wall of the receptacle body to vary internal pressure...

Benefits of technology

[0009]The present invention has been made to solve the above problems occurring in the prior art, and an object of the present invention is to provide a receptacle with a lid, in which a packing having a foldable wing section is integrally formed with the lid through a dual injection molding scheme, such as an insert molding scheme, so that, when the lid is press-fitted i

Problems solved by technology

However, there is a disadvantage in that the packing may be unintentionally separated from the lid if the packing is not precisely assembled with the lid because the packing is deformed as internal pressure of the recept
