Novel design of a closure means

Abstract

A closure means for closing an opening of a container includes a lid assembly having a lid cover, configured to provide an upper plate and a lower plate connecting the upper plate via a standing wall. The upper plate has at least one hinge member. A wing member includes a handling portion, a flipping portion, and a stopper portion. The wing member pivotably connects to the lid cover at the hinge member and moves between a first position and a second position. The upward movement of the wing member is limited. A gas channeling means having a first configuration where the container is closed with the closure means. The gas channeling means is biased. The wing member moves from the first position to the second position causing the closure means being moved upwards automatically and causing the gas channeling means transiting from a biased condition to an unbiased condition.

What is claimed is: 
     
         1 . A closure means for closing an opening of a container, said closure means comprising:
 a lid assembly, comprising:

 at least one wing member comprising a handling portion, a flipping portion, and a stopper portion, said wing member pivotably connecting to said lid cover at said hinge member and thus movable between a first position where said stopper portion being away from said upper plate of said lid cover and a second position where said stopper portion being engaged with said upper plate of said lid cover and thus the upward movement of said wing member with respect to said lid cover being limited; and 
 a gas channeling means; 
   characterized in that,   in a first configuration where said container being closed with said closure means, said gas channeling means being biased; and   said wing member being moved from said first position to said second position causing said lid cover being moved upwards automatically and causing said gas channeling means transiting from a biased condition to an unbiased condition.   
     
     
         2 . The closure means according to  claim 1 , characterized in that, said gas channeling means being made of resilient materials. 
     
     
         3 . The closure means according to  claim 1 , characterized in that, said gas channeling means being biased by a portion of said wing member. 
     
     
         4 . The closure means according to  claim 1 , characterized in that, said lid cover being configured to comprise an aperture to accommodate said gas channeling means. 
     
     
         5 . The closure means according to  claim 1 , characterized in that, said gas channeling means being profiled to have a hollow structure having a first end facing to an interior of the container and a second end facing to the atmosphere. 
     
     
         6 . The closure means according to  claim 5 , characterized in that, in said first configuration, said second end of said gas channeling means being biased. 
     
     
         7 . The closure means according to  claim 1 , characterized in that, said closure means further comprising a sealing element, fittingly mounted around said standing wall of said lid cover. 
     
     
         8 . The closure means according to  claim 1 , characterized in that, in said second position, said stopper portion of said wing member engaging with said upper plate of said lid cover. 
     
     
         9 . The closure means according to  claim 1 , characterized in that, in said second position, said stopper portion of said wing member engaging with said upper plate of said lid cover, wherein the angle between said flipping portion and said lid cover does not exceed 90 degrees. 
     
     
         10 . The closure means according to  claim 1 , characterized in that, in a second configuration where said closure means being assembled to said container but yet unsealing said container, said gas channeling means being unbiased and/or said wing member being moved from said second position to said first position causing said lid cover being moved downwards automatically. 
     
     
         11 . The closure means according to  claim 5 , characterized in that, in a second configuration where said closure means being assembled to said container but yet unsealing said container, said second end of said gas channeling means being unbiased and/or said wing member being moved from said second position to said first position causing said lid cover being moved downwards automatically. 
     
     
         12 . The closure means according to  claim 10 , characterized in that, the transition from said second configuration to said first configuration can be operated by pushing said lid cover downwards. 
     
     
         13 . The closure means according to  claim 1 , characterized in that, when said lid cover is provided with two wing members, in said first configuration where said container being closed with said closure means, said wing members being moved from said first position to said second position causing said lid cover being moved vertically upwards automatically. 
     
     
         14 . The closure means according to  claim 7 , characterized in that, said sealing element is received in said container after said container is sealed with said closure means. 
     
     
         15 . The closure means according to  claim 1 , characterized in that,
 said handling portion is provided with at least one locking member; and   said container having surrounding wall having a first edge connecting to a bottom and a second edge defining an open-top for said container, wherein said second edge is configured to engage with said locking member.   
     
     
         16 . The closure means according to  claim 15 , characterized in that, said locking member is selected from an inwardly protruded finger and/or an elevation for interacting with said second edge of said container. 
     
     
         17 . The closure means according to  claim 1 , characterized in that, said lid cover is provided with a tooth member, such that the interaction between said tooth member and said flipping portion of said wing member provides a locking effect. 
     
     
         18 . The closure means according to  claim 17 , characterized in that,
 in said first configuration, said tooth member at least being covered by said flipping portion; and   in said second configuration, the interaction between said tooth member and said flipping portion being free.   
     
     
         19 . The closure means according to  claim 10 , said container having surrounding wall having a first edge connecting to a bottom and a second edge defining an open-top for said container, characterized in that,
 in said first configuration, the engagement between said flipping portion of said wing member and said second edge of said container being surface contact.   
     
     
         20 . The closure means according to  claim 19 , characterized in that, in said second configuration, the engagement between said flipping portion of said wing member and said second edge of said container being line contact or point contact.
