Abstract
An inkjet storage container sealing mechanism is comprised of a cover, a receptacle, a gasket compressed normal to its insertion and a support member to maintain a seal that is resistant to ink and air penetration. The receptacle has sidewalls that form an opening. A gasket is stretched over a portion the cover, then the gasket and the portion of the cover is inserted into the opening of the receptacle. The gasket forms a seal between the cover and the receptacle. The compressive forces acting on the gasket to form the seal do not contribute additional forces to a mechanical joining mechanism, which attaches the cover to the receptacle. The support member prevents the sidewalls of the receptacle from deflecting to help maintain the seal.
Claims10
An inkjet storage container sealing mechanism comprising:
- a receptacle having an inside surface, an outside surface and a peripheral lip surrounding an opening in said receptacle, a gasket seal area inside said opening;
- and a beveled edge surrounding said opening and formed into said receptacle and extending to said gasket seal area;
- a cover having an inside surface, an outside surface, and a flange member disposed on said cover outside surface, said cover adapted to fit said opening with said cover outside surface facing said receptacle inside surface, and said flange member adapted to mate with said peripheral lip;
- and
- a gasket surrounding said opening and disposed between said receptacle inside surface and said cover outside surface whereby a direction of compression of said gasket is normal to said receptacle inside surface and normal to said cover outside surface and the direction of compression is normal to the direction of insertion of said cover into the opening in said receptacle whereby the normal compression of said gasket is done gradually during an insertion of said cover into said opening of said receptacle.
An inkjet storage container comprising:
- a cover including;
- at least two snap lock mechanisms, and
- a gasket receiving area;
- a receptacle including;
- a plurality of sidewalls,
- at least two sidewall protrusions disposed on said plurality of sidewalls, said at least two snap lock mechanisms interlockable into said at least two sidewall protrusions,
- an opening defined by said plurality of sidewalls,
- a gasket seal area inside said opening, and
- a beveled edge surrounding said opening and formed into said receptacle and extending to said gasket seal area;
- a gasket disposed on said cover such that said gasket receiving area of said cover is circumscribed by said gasket, and said gasket inscribed within said gasket seal area of said receptacle, said gasket compressed between said cover and said opening of said receptacle in a direction normal to said receptacle gasket seal area and said gasket receiving area, whereby the compression of said gasket is done gradually during insertion of said cover subassembly into said opening of said receptacle and the direction of compression is normal to the direction of insertion of said cover into the opening in said receptacle;
- and
- a support structure on said cover circumscribing said plurality of sidewalls of said receptacle after assembly whereby said seal is maintained.
