Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
144 words
A container comprising: a wrapped side wall made from generally rigid foam sheet material having a lapped side seam, defining openings at opposite ends thereof; a preshaped bottom wall made from generally rigid foam sheet material, said bottom wall having its central portion lying generally perpendicular to the axis of the side wall and an annular shirt extending (away from the general plane of the) outwardly of said central portion into proximity with one end of said side wall , said skirt defining an outer diameter (slightly) no less than the inner diameter of (one of) the said opening(s) in said container at said one end of said side wall whereby said bottom wall may be fitted snugly into said opening at said one end of said side wall; and a heat-sealed seam joining the skirt to said one end of the side wall.
Claim 2
Dependent Claim
144 words
A container comprising: a wrapped side wall made from generally rigid foam sheet material having a lapped side seam, defining openings at opposite ends thereof; a preshaped bottom wall made from generally rigid foam sheet material, said bottom wall having its central portion lying generally perpendicular to the axis of the side wall and an annular shirt extending (away from the general plane of the) outwardly of said central portion into proximity with one end of said side wall , said skirt defining an outer diameter (slightly) no less than the inner diameter of (one of) the said opening(s) in said container at said one end of said side wall whereby said bottom wall may be fitted snugly into said opening at said one end of said side wall; and a heat-sealed seam joining the skirt to said one end of the side wall.
Claim 3
Dependent Claim
82 words
A container as described in claim 1 further characterized by said side wall being frustoconical in shape and narrower at the bottom edge and said skirt being frustoconical in shape and being wider at the bottom and with the upper edge of the skirt joining the central portion, said heat-sealed seam joining only the lower portion of the skirt and the bottom margin of the side wall and with the side wall and skirt diverging from one another in an upwardly direction.
Claim 4
Dependent Claim
27 words
A container as described in claim 1 further characterized by said side wall being turned over at the upper edge to lend lateral stiffness to the container.
Claim 5
Dependent Claim
57 words
A container as described in claim 1 further characterized by said lapped seam being formed by overlapping the edges of the blank from which the side wall is made and welding together the overlapped margins, the thickness of the side wall at the overlapped edges being substantially less than twice the thickness of the side wall material.
Claim 6
Dependent Claim
54 words
A container as described in claim 1 further characterized by said bottom skirt extending upwardly from the central portions and lying flush against the side wall, the lower margin of the side wall being turned inwardly beneath the periphery of the central portion of the bottom with said margins being sealed to the bottom.
Claim 7
Dependent Claim
57 words
A container as described in claim 5 further characterized by said lapped seam being formed by overlapping the edges of the blank from which the side wall is made and welding together the overlapped margins, the thickness of the side wall at the overlapped edges being substantially less than twice the thickness of the side wall material.
Claim 8
Dependent Claim
83 words
A container as described in claim (6) 4 further characterized by said side wall be frustoconical in shape and narrower at the bottom edge and said skirt being frustoconical in shape and being wider at the bottom and with the upper edge of the skirt joining the central portion, said heat-sealed seam joining only the lower portion of the skirt and the bottom margin of the side wall and with the side wall and skirt diverging from one another in an upwardly direction.
Claim 9
Dependent Claim
24 words
A container as described in claim (6) 4 further characterized by said side wall and bottom having an approximate stock thickness of 0.110 inch.
Claim 10
Dependent Claim
101 words
A container as described in claim 8 further characterized by said side wall being frustoconical in shape and norrower at the bottom edge and said skirt being frustoconical in shape and being wider at the bottom and with the upper edge of the skirt joining the central portion, said heat-sealed seam joining only the lower portion of the skirt and the bottom margin of the side wall and with the side wall and skirt diverging from one another in an upwardly direction, said turned over portion of the rim being expanded to a thickness exceeding the thickness of the side wall.
Claim 11
Dependent Claim
98 words
A container comprising: a wrapped side wall made from foam sheet material having a heat-sealed lapped side seam and defining openings at opposite ends thereof; a preshaped bottom wall made froM foam sheet material having a central portion disposed transversely of the longitudinal axis of the side wall and an annular skirt extending outwardly from said central portion having one surface thereof in proximity with the inner surface of said side wall at one end of the latter; and a heat-sealed bottom seam joining said one surface of said skirt to said inner surface of said side wall.
Claim 12
Dependent Claim
98 words
A container comprising: a wrapped side wall made from foam sheet material having a heat-sealed lapped side seam and defining openings at opposite ends thereof; a preshaped bottom wall made froM foam sheet material having a central portion disposed transversely of the longitudinal axis of the side wall and an annular skirt extending outwardly from said central portion having one surface thereof in proximity with the inner surface of said side wall at one end of the latter; and a heat-sealed bottom seam joining said one surface of said skirt to said inner surface of said side wall.
Claim 13
Dependent Claim
26 words
The invention defined in claim 10, wherein said side wall is substantially frustoconical; and wherein said bottom wall is heat-sealed thereto adjacent the smallest end thereof.
Claim 14
Dependent Claim
24 words
The invention defined in claim 10, wherein said side wall is turned inwardly beneath said skirt in the provision of said heat-sealed bottom seam.
Claim 15
Dependent Claim
