Abstract
Abstract The open end of a tubular sheet metal container of rectangular cross-section is closed by telescoping down over an outwardly and downwardly turned flange near the container lip a cover of resilient plastic having a depending peripheral skirt with a tab depending from one shorter end thereof and secured against the outer side of the container wall by integral projections pressed through holes in such wall. The cover is held releasably in closed position by nibs projecting inwardly from the skirt near the free end thereof and interlocked beneath the edge of the hem flange.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
282 words
A dispensing container having, in combination, a sheet metal tubular body of rectangular cross-section having a lip around its open end, a generally flat and rectangular cover of molded resilient plastic having a depending peripheral skirt adapted to telescope closely down over the exterior of the lip around the entire periphery of said open end, a generally flat tab molded integral with the lower edge of said skirt and coNstituting a depending extension of the skirt across one edge of the cover so as to lie against the outer surface of one upright wall of said body, said one wall having holes therethrough laterally spaced apart below the edge of said skirt and within the area of said tab, projections of larger radial cross-section than said holes molded integral with said tab and pressed into and through said holes to cause the edges of the holes to bite into the sides of the projections and anchor the tab securely to said body and flat against said one body wall, the junction between said skirt and said tab being sufficiently thin and flexible to form a hinge disposed outside of said one wall and substantially along the skirt edge so as to permit swinging of the entire cover into and out of telescoping and abutting relation with said body lip whereby the entire cross-sectional area of said open end of the body is opened and exposed when the cover is swung away from closed position, and means on the interior of said skirt and the exterior of said lip interengageable with each other as said cover comes into abutment with said lip to hold the cover releasably in closed position against the lip.
Claim 2
Dependent Claim
282 words
A dispensing container having, in combination, a sheet metal tubular body of rectangular cross-section having a lip around its open end, a generally flat and rectangular cover of molded resilient plastic having a depending peripheral skirt adapted to telescope closely down over the exterior of the lip around the entire periphery of said open end, a generally flat tab molded integral with the lower edge of said skirt and coNstituting a depending extension of the skirt across one edge of the cover so as to lie against the outer surface of one upright wall of said body, said one wall having holes therethrough laterally spaced apart below the edge of said skirt and within the area of said tab, projections of larger radial cross-section than said holes molded integral with said tab and pressed into and through said holes to cause the edges of the holes to bite into the sides of the projections and anchor the tab securely to said body and flat against said one body wall, the junction between said skirt and said tab being sufficiently thin and flexible to form a hinge disposed outside of said one wall and substantially along the skirt edge so as to permit swinging of the entire cover into and out of telescoping and abutting relation with said body lip whereby the entire cross-sectional area of said open end of the body is opened and exposed when the cover is swung away from closed position, and means on the interior of said skirt and the exterior of said lip interengageable with each other as said cover comes into abutment with said lip to hold the cover releasably in closed position against the lip.
Claim 3
Dependent Claim
71 words
A container as defined in claim 1, in which the ends of the rectangular body cross-section and of said skirt are substantially shorter than the sides and said tab depends from one of said shorter skirt ends so that the container contents may, after opening of said cover, be poured out of the container across the opposite short end of said lip without contact with the hinged end of the skirt.
Claim 4
Dependent Claim
42 words
A container as defined in claim 1, in which said tab is formed as a single piece of said plastic integrally and rigidly joining said anchoring projections so as to maintain accurate spacing thereof during insertion of the projections through said holes.
Claim 5
Dependent Claim
53 words
A container as defined in claim 1, in which said body lip is formed by an outturned hem and said holding means includes a nib integral with said projecting inwardly from said skirt at a point spaced from said hinge and adapted to snap in beneath the free lower edge of said hem.
Claim 6
Dependent Claim
73 words
A container as defined in claim 4 in which said nib is long enough to hold the cover securely in its initial abutment with said lip while permitting its tip to be sheared away during the initial opening of the cover, enough of the nib remaining after such shearing to be compressed in passing said hem flange and snap in beneath the edge thereof in subsequent closings of the cover against said lip.
Claim 7
Dependent Claim
28 words
A container as defined in claim 5, having a plurality of said nibs projecting inwardly from opposite sides of said skirt adjacent the free end of said cover.
Claim 8
Dependent Claim
61 words
A container as defined in claim 1, in which said body is composed of a sheet of metal whose ends are bent and interlocked with each other to form a seam extending downwardly from said lip along the inner surface of said one end wall, the outer surface of such wall abutting the inner face of said tab being substantially flat.
