Closure and an assembly of the closure with a container

Abstract

An assembly of a closure with a container, for sealing of the container, comprises the container having an inner container surface defining a cavity opening to ambient through an opening, the closure comprising an upper portion and a lower portion, the lower portion having a lower lateral surface, the lower portion being adapted to be inserted into the opening of the container and two grooves provided on the lower lateral surface and adapted to receive two respective sealing members, the two grooves being separated by a predetermined distance, the two sealing members provided in the two respective grooves, the two sealing members being adapted to provide sealing between the lower lateral surface and the inner container surface, wherein the lower lateral surface, the inner container surface and the two auxiliary sealing members together define an annular space and a barrier sealant in the annular space.

1 . A closure for sealing a container having an inner container surface defining a cavity opening to ambient through an opening, the closure comprising:
 an upper portion and a lower portion, wherein the upper portion is sized so as to not fit within a container and the lower portion having a lower lateral surface, wherein the lower portion is configured to be inserted into a cavity opening of a container;   two grooves provided on the lower lateral surface configured to receive two respective sealing members, wherein the two grooves are separated by a predetermined distance;   the two sealing members provided in the two respective grooves, wherein the two sealing members are configured to provide sealing between the lower lateral surface and the inner container surface, wherein the lower lateral surface, the inner container surface and the two auxiliary sealing members together define an annular space; and   a barrier sealant in the annular space, wherein the closure seals the container preventing gas or liquid from escaping the opening.   
     
     
         2 . The assembly as claimed in  claim 1 , wherein the sealing members are selected from a group consisting of O-rings and barbs made up of a synthetic polymer. 
     
     
         3 . The assembly as claimed in  claim 1 , further comprising a clamping arrangement adapted to clamp the closure with the container. 
     
     
         4 . The assembly as claimed in  claim 1 , wherein the closure further comprises one or more passages connecting one or more respective sealant receiving ports in the upper portion with one or more respective lateral openings, between the two grooves, in the lower lateral surface. 
     
     
         5 . The assembly as claimed in  claim 1 , further comprising one or more plugs provided at the one or more respective sealant receiving ports, the one or more plugs being adapted to prevent the barrier sealant from escaping through the one or more respective passages. 
     
     
         6 . The assembly as claimed in  claim 1 , wherein the closure is made up of material selected from a group consisting of metals, ceramics, glasses and polymers. 
     
     
         7 . The assembly as claimed in  claim 1 , wherein the upper portion further comprises a lip portion, a width of the lip portion being greater than a width of the opening of the container. 
     
     
         8 . The assembly as claimed in  claim 1 , wherein the upper portion further comprises a second cavity. 
     
     
         9 . The assembly as claimed in  claim 1 , wherein the second cavity is adapted to receive one or more of an environmental indicator and an environmental control element. 
     
     
         10 . The assembly as claimed in  claim 1 , further comprising a second closure having a substantially flat disk fastened to the container and placed above the closure. 
     
     
         11 . The assembly as claimed in  claim 1 , further comprising a flat glass plate placed between the substantially flat disk and the closure. 
     
     
         12 . The assembly as claimed in  claim 1 , wherein the upper portion further comprises two auxiliary grooves provided at an upper surface of the upper portion, the two auxiliary groves being adapted to receive two respective auxiliary sealing members, wherein the two auxiliary grooves are oriented in a direction normal to the two grooves. 
     
     
         13 . The assembly as claimed in  claim 1 , wherein the one or more passages further connect the one or more respective sealant receiving ports in the upper portion with one or more respective upper openings, between the two auxiliary grooves, in the upper surface. 
     
     
         14 . The assembly as claimed in  claim 1 , further comprising the two auxiliary sealing members adapted to provide sealing between a lower plate surface of the flat glass plate and the upper surface, wherein the upper surface, the lower plate surface and the two auxiliary sealing members define an auxiliary annular space. 
     
     
         15 . The assembly as claimed in  claim 1 , wherein the closure further comprises one or more content exchange passages connecting the cavity to one or more respective content exchange ports in the upper portion, the one or more content exchange passages being adapted to receive and deliver content in and out of the cavity, respectively. 
     
     
         16 . The assembly as claimed in  claim 1 , further comprising one or more content exchange valves provided at the one or more respective content exchange ports and adapted to open and close the one or more respective content exchange passages to the atmosphere. 
     
     
         17 . The assembly as claimed in  claim 1 , wherein the barrier sealant is selected from a group consisting of an aqueous solution, a non-aqueous solution, grease, epoxy, acrylic, polysulfide, UV-cure, time-cure, polyurethane and adhesive.
