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.

1 . A receptacle comprising:
 a receptacle body;   a lid having an air vent device at an upper portion thereof and a support wall at a lower portion thereof; and   a packing which closely makes contact with an inner wall of the receptacle body and includes a fixing member closely making contact with one side of the support wall and a wing section extending from the fixing member while being integrally formed with the fixing member.   
   
   
       2 . The receptacle as claimed in  claim 1 , wherein a passage hole is formed at an upper portion of the support wall of the lid and an upper portion of the fixing member of the packing is rested on an upper surface of the lid by passing through the passage hole. 
   
   
       3 . The receptacle as claimed in  claim 2 , wherein a recess is formed on the upper surface of the lid such that the upper portion of the fixing member of packing is rested in the recess. 
   
   
       4 . The receptacle as claimed in  claim 1 , wherein a step portion is formed at an upper portion of the support wall of the lid so that a rim is provided at the upper portion of the support wall of the lid and the rim is closely fitted in a rim section of the receptacle body, which is formed at an upper portion of the receptacle body. 
   
   
       5 . The receptacle as claimed in  claim 2 , wherein a step portion is formed at an upper portion of the support wall of the lid so that a rim is provided at the upper portion of the support wall of the lid and the rim is closely fitted in a rim section of the receptacle body, which is formed at an upper portion of the receptacle body. 
   
   
       6 . The receptacle as claimed in  claim 3 , wherein a step portion is formed at an upper portion of the support wall of the lid so that a rim is provided at the upper portion of the support wall of the lid and the rim is closely fitted in a rim section of the receptacle body, which is formed at an upper portion of the receptacle body. 
   
   
       7 . The receptacle as claimed in  claim 4 , wherein a size of the rim section of the receptacle body is substantially identical to a size of the rim of the lid, and a step section is formed at a lower end of the rim section such that a front end of the wing section of the packing makes contact with the step section. 
   
   
       8 . The receptacle as claimed in  claim 5 , wherein a size of the rim section of the receptacle body is substantially identical to a size of the rim of the lid, and a step section is formed at a lower end of the rim section such that a front end of the wing section of the packing makes contact with the step section. 
   
   
       9 . The receptacle as claimed in  claim 6 , wherein a size of the rim section of the receptacle body is substantially identical to a size of the rim of the lid, and a step section is formed at a lower end of the rim section such that a front end of the wing section of the packing makes contact with the step section. 
   
   
       10 . The receptacle as claimed in  claim 1 , wherein the packing is made from a plastic material including koma. 
   
   
       11 . The receptacle as claimed in  claim 2 , wherein the packing is made from a plastic material including koma.
