Abstract
Abstract A container is provided having a body adapted to contain a product therein and having a bottom wall and a side wall which terminates in a first circumferential bead defining an open end in the body. A closure is provided for the body and such closure has a main portion adjoined at its outer edge by an annular flange with the annular flange terminating in a second circumferential bead; and an annular indentation is provided in the flange and first bead which cooperates with seal means for the closure to provide an improved seal between the closure and the first annular bead.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
304 words
A container comprising, a metallic container body adapted to contain a product therein and having a bottom wall and a side wall terminating in a first deformable circumferential bead of substantially tubular toroidal form defining an open end in said container body, a deformable metallic closure for said container body, said closure having a main portion adjoined at its outer edge by an annular flange, said flange terminating in a second circumferential bead, force transmitting means provided as an integral part of said main portion, seal means between said closure and first bead, and an annular indentation in said flange and first bead which cooperates with said seal means to provide an improved seal between said closure and said first annular bead, said flange having a roughly U-shaped cross-sectional configuration defined by a bight having an inner leg portion and an outer leg portion with said leg portions extending downwardly from opposite ends of said bight and said annular indentation being in the form of a roughly V-shaped indentation in said inner leg portion and in said first bead, said annular indentation positions said closure on said container body and simultaneously results in a deformation of a portion of said first bead which is a part plastic deformation and a part elastic deformation, said part elastic deformation causing said portion of said first bead to be resiliently urged more tighly against said closure, said resiliently urged portion cooperating with said seal means to provide said improved seal, said force transmitting means causing release of said inner leg portion of said flange away from said first bead by shearing said seal means upon urging and permanently deforming at least part of said main body portion toward the center of said container body enabling removal of said closure simply by lifting upwardly against said second bead.
Claim 2
Dependent Claim
304 words
A container comprising, a metallic container body adapted to contain a product therein and having a bottom wall and a side wall terminating in a first deformable circumferential bead of substantially tubular toroidal form defining an open end in said container body, a deformable metallic closure for said container body, said closure having a main portion adjoined at its outer edge by an annular flange, said flange terminating in a second circumferential bead, force transmitting means provided as an integral part of said main portion, seal means between said closure and first bead, and an annular indentation in said flange and first bead which cooperates with said seal means to provide an improved seal between said closure and said first annular bead, said flange having a roughly U-shaped cross-sectional configuration defined by a bight having an inner leg portion and an outer leg portion with said leg portions extending downwardly from opposite ends of said bight and said annular indentation being in the form of a roughly V-shaped indentation in said inner leg portion and in said first bead, said annular indentation positions said closure on said container body and simultaneously results in a deformation of a portion of said first bead which is a part plastic deformation and a part elastic deformation, said part elastic deformation causing said portion of said first bead to be resiliently urged more tighly against said closure, said resiliently urged portion cooperating with said seal means to provide said improved seal, said force transmitting means causing release of said inner leg portion of said flange away from said first bead by shearing said seal means upon urging and permanently deforming at least part of said main body portion toward the center of said container body enabling removal of said closure simply by lifting upwardly against said second bead.
Claim 3
Dependent Claim
25 words
A container as set forth in claim 1 in which said force transmitting means comprises a central raised portion arranged concentrically with said second bead.
Claim 4
Dependent Claim
41 words
A container as set forth in claim 1 in which said force transmitting means comprises a plurality of raised portions in said main portion of said closure, said raised portions having the same wall thickness as the remainder of said closure.
Claim 5
Dependent Claim
46 words
A container as set forth in claim 3 in which said plurality of raised portions comprises a plurality of key-hole shaped portions arranged 90° apart with each of said key-hole shaped portions having a bulbous end arranged closely adjacent to the center of said main portion.
Claim 6
Dependent Claim
26 words
A container as set forth in claim 3 in which said plurality of raised portions comprises a plurality of outwardly convex portions of circular peripheral outline.
Claim 7
Dependent Claim
62 words
A container as set forth in claim 3 in which said plurality of raised portions comprises a plurality of three portions at the terminal edge of a roughly triangular raised portion, said triangular raised portion having an apex adjacent the center of said closure and said three projections adjoining an inner side thereof which adjoins said inner leg portion of said flange.
Claim 8
Dependent Claim
47 words
A container as set forth in claim 3 in which said plurality of raised portions comprises a set of three elongated parallel raised portions provided within a 90° sector of said main portion, said set of three raised portions extending toward the center of said main portion.
Claim 9
Dependent Claim
30 words
A container as set forth in claim 7 and further comprising another set of three elongated parallel raised portions arranged substantially diametrically opposite said first-named set of three raised portions.
Claim 10
Dependent Claim
30 words
A container as set forth in claim 8 and further comprising a plurality of raised portions extending the full width of said closure while being arranged perpendicular to said sets.
Claim 11
Dependent Claim
40 words
A container as set forth in claim 3 in which said plurality of raised portions comprises a plurality of raised portions which extend about the entire periphery of said main portion of said closure in substantially equal angularly spaced relation.
Claim 12
Dependent Claim
32 words
A container as set forth in claim 10 in which said plurality of raised portions comprises a plurality of substantially triangular portions having apexes pointing toward the center of said main portion.
Claim 13
Dependent Claim
57 words
A container as set forth in claim 3 in which said plurality of raised portions comprises a raised disc-like circular part provided at the center of said main portion and a plurality of radially extending parts extending from said circular part and having terminal ends which adjoin said inner leg of said peripheral flange of said closure.
Claim 14
Dependent Claim
40 words
A container as set forth in claim 3 in which said plurality of raised portions comprises a plurality of three raised portions having longitudinal axes which extend toward the center of the main body portion in a substantially converging manner.
Claim 15
Dependent Claim
45 words
A container as set forth in claim 3 in which said plurality of raised portions comprises a plurality of two key-hole shaped raised portions arranged approximately 90° apart with each of the key-hole shaped portions being arranged adjacent the center of the main body portion.
Claim 16
Dependent Claim
23 words
A container as set forth in claim 3 in which said container body and closure are made of a metallic material containing aluminum.
