Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
200 words
A container having the general shape of a bowl or cup which is fabricated from a single sheet of flexible sheet material of generally circular outline and which is cut and scored so as to provide in the set-up condition a bottom wall forming panel of hexagonal outline and upwardly and outwardly inclined side wall forming panel portions which have hinged connections with the peripheral edges of the bottom wall forming panel on straight lines, said side wall forming panel portions being integrally connected at adjoining ends by triangular web portions which are folded on upwardly opening V-shaped score lines extending between the peripheral edge of said bottom wall forming panel and the top edge of the adjoining side wall forming panel portions, said folded web portions being secured between adjoining margins of said side wall forming panel portions which overlap so as to provide gusset seams connecting said side wall forming panel portions, said side wall forming panel portions terminating at their top edges at an outwardly and downwardly rolled edge formation which extends on a continuous curved line in the plane of the top edge of the container and forms a rim for attaching a Closure member thereon.
Claim 2
Dependent Claim
200 words
A container having the general shape of a bowl or cup which is fabricated from a single sheet of flexible sheet material of generally circular outline and which is cut and scored so as to provide in the set-up condition a bottom wall forming panel of hexagonal outline and upwardly and outwardly inclined side wall forming panel portions which have hinged connections with the peripheral edges of the bottom wall forming panel on straight lines, said side wall forming panel portions being integrally connected at adjoining ends by triangular web portions which are folded on upwardly opening V-shaped score lines extending between the peripheral edge of said bottom wall forming panel and the top edge of the adjoining side wall forming panel portions, said folded web portions being secured between adjoining margins of said side wall forming panel portions which overlap so as to provide gusset seams connecting said side wall forming panel portions, said side wall forming panel portions terminating at their top edges at an outwardly and downwardly rolled edge formation which extends on a continuous curved line in the plane of the top edge of the container and forms a rim for attaching a Closure member thereon.
Claim 3
Dependent Claim
66 words
A container as set forth in claim 1 wherein said side wall panel portions have upwardly bowed score lines in the bottom areas thereof which form with the associated hinge connections between the bottom wall and the side wall panel portions flat panel sections at the bottom of the side wall which merge at the top into curved top sections of said side wall panel portions.
Claim 4
Dependent Claim
34 words
A container as set forth in claim 2 wherein said upwardly bowed score lines extend from points of intersection of adjoining straight hinge lines which define the perimeter of the bottom wall forming panel.
Claim 5
Dependent Claim
200 words
A container in the form of a bowl or cup which is fabricated from a one piece blank of folded sheet material comprising a bottom wall forming panel having a perimeter defined by straight line hinge connections with upstanding side wall forming panel portions, which side wall forming panel portions are disposed in upwardly and outwardly inclined relation and integrally connected by triangular webs which are folded on upwardly extending hinge lines to lie between adjoining margins of the side wall forming panel portions and which are adhesively secured to the confronting faces thereof to form gusset seams, said side wall forming panel portions extending at their top edges to a relatively rigid, outwardly rolled continuous rim formation for reinforcing the side wall top edge and for receiving thereon a closure member, and said side wall forming panel portions each having a web section which extends adjacent the hinge connection with the bottom wall forming panel and which is defined by an upwardly bowed fold line and a straight bottom edge, said web section having a substantially flat panel area adjacent the bottom edge thereof and merging at its top edge into the curved top area of the panel portion.
Claim 6
Dependent Claim
200 words
A container in the form of a bowl or cup which is fabricated from a one piece blank of folded sheet material comprising a bottom wall forming panel having a perimeter defined by straight line hinge connections with upstanding side wall forming panel portions, which side wall forming panel portions are disposed in upwardly and outwardly inclined relation and integrally connected by triangular webs which are folded on upwardly extending hinge lines to lie between adjoining margins of the side wall forming panel portions and which are adhesively secured to the confronting faces thereof to form gusset seams, said side wall forming panel portions extending at their top edges to a relatively rigid, outwardly rolled continuous rim formation for reinforcing the side wall top edge and for receiving thereon a closure member, and said side wall forming panel portions each having a web section which extends adjacent the hinge connection with the bottom wall forming panel and which is defined by an upwardly bowed fold line and a straight bottom edge, said web section having a substantially flat panel area adjacent the bottom edge thereof and merging at its top edge into the curved top area of the panel portion.
