Abstract

Abstract This invention relates to a carton for holding a ball with diametrically disposed portions of its surface exposed, said carton having rectangularly arranged side walls with closure flaps at the lower and upper ends which collectively form spaced parallel flat, bottom and top walls, the distance between which corresponds substantially to the diameter of the ball, wherein two of the side walls are convex and the distance between them corresponds substantially to said diameter of the ball and wherein the other two sides are concave and contain centrally located openings of substantially elliptical configuration through which diametrical surface portions of the ball project; and a blank adapted to be folded up to form the aforesaid carton.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 223 words
A carton comprising rectangularly arranged curved sidewalls having sides and ends and closure means at the ends of the sidewalls which form bottom and top walls of rectangular configuration, said sidewalls and end walls being comprised of a flexible material, characterized in that two of the opposed sidewalls are convex, another two are concave and the end walls are flat, that the interior distance between the convex side walls midway between the top and bottom walls is substantially equal to the interior distance between the top and bottom walls, that the interior distance between the concave side walls midway between the top and bottom walls is less than the interior distance between the top and bottom walls and that said concave walls contain centrally located aligned openings of curvilinear configuration of such dimension that the convex surface of a body deposed within the carton having x and z axes corresponding to the distance between the top and bottom will project through said openings in engagement with the edges thereof, and that said upper ends of the sidewalls have a collective length at least equal to the circumference of a circle whose radius is equal to one-half the distance between the top and bottom wall, so that said flexible sidewalls at said upper ends can be distended to receive a body of said radius.
Claim 2
Dependent Claim 223 words
A carton comprising rectangularly arranged curved sidewalls having sides and ends and closure means at the ends of the sidewalls which form bottom and top walls of rectangular configuration, said sidewalls and end walls being comprised of a flexible material, characterized in that two of the opposed sidewalls are convex, another two are concave and the end walls are flat, that the interior distance between the convex side walls midway between the top and bottom walls is substantially equal to the interior distance between the top and bottom walls, that the interior distance between the concave side walls midway between the top and bottom walls is less than the interior distance between the top and bottom walls and that said concave walls contain centrally located aligned openings of curvilinear configuration of such dimension that the convex surface of a body deposed within the carton having x and z axes corresponding to the distance between the top and bottom will project through said openings in engagement with the edges thereof, and that said upper ends of the sidewalls have a collective length at least equal to the circumference of a circle whose radius is equal to one-half the distance between the top and bottom wall, so that said flexible sidewalls at said upper ends can be distended to receive a body of said radius.
Claim 3
Dependent Claim 35 words
A carton according to claim 1, wherein the collective lengths of the lower ends of the side walls correspond to that of the upper ends of the side walls so that the carton is symmetrical.
Claim 4
Dependent Claim 16 words
A carton according to claim 1, wherein the convex side walls have a substantially cylindrical curvature.
Claim 5
Dependent Claim 23 words
A carton according to claim 1, wherein the concave side walls have a substantially cylindrical curvature and the openings therein are substantially elliptical.
Claim 6
Dependent Claim 71 words
A carton according to claim 1, wherein the closure means comprises dust flaps on two of the opposed side walls at the lower and upper ends thereof foldable across the bottom and top openings and closure flaps on the other two opposed side walls at the lower and upper ends provided with interengageable components by means of which they may be secured in overlapping engagement across the bottom and top openings.
Claim 7
Dependent Claim 36 words
A carton according to claim 5, wherein the closure flaps at the top of the carton embody handle members adapted to be disposed in a position perpendicular to the top when the closure flaps are interengaged.
Claim 8
Dependent Claim 20 words
A carton according to claim 1, wherein the convex side walls contain fold lines medially thereof from bottom to top.
Claim 9
Dependent Claim 205 words
A flat blank for forming a carton comprising a substantially rectangular sheet of flexible board having spaced parallel longitudinally extending fold lines and transverselly extending longitudinally spaced curved fold lines intersecting the longitudinally extending fold lines which collectively divide the sheet into four panels such that the ends of each panel coincide with the longitudinally extending fold lines and the side edges are transverse thereto, and outwardly of the longitudinally extended fold lines there are closure members which collectively form the ends of the carton when the blank is folded on such fold lines, said side edges of the alternate panels being concave and the side edges of the intermediate panels being convex, wherein the width of the alternate panels at their ends are equal to the width of the intermediate panels midway between their ends and wherein the intermediate panels contain centrally located, substantially curvilinear openings, said sheet being adapted to be folded on said transversely extending fold lines to dispose the panels rectIlinearly, means at one end of the sheet for joining the two end panels of the sheet to each other and means associated with the closure members interengageable by folding of the closure members to form the ends of the carton.
Claim 10
Dependent Claim 205 words
A flat blank for forming a carton comprising a substantially rectangular sheet of flexible board having spaced parallel longitudinally extending fold lines and transverselly extending longitudinally spaced curved fold lines intersecting the longitudinally extending fold lines which collectively divide the sheet into four panels such that the ends of each panel coincide with the longitudinally extending fold lines and the side edges are transverse thereto, and outwardly of the longitudinally extended fold lines there are closure members which collectively form the ends of the carton when the blank is folded on such fold lines, said side edges of the alternate panels being concave and the side edges of the intermediate panels being convex, wherein the width of the alternate panels at their ends are equal to the width of the intermediate panels midway between their ends and wherein the intermediate panels contain centrally located, substantially curvilinear openings, said sheet being adapted to be folded on said transversely extending fold lines to dispose the panels rectIlinearly, means at one end of the sheet for joining the two end panels of the sheet to each other and means associated with the closure members interengageable by folding of the closure members to form the ends of the carton.
Claim 11
Dependent Claim 50 words
A blank according to claim 8, wherein said means for joining the end panels comprises a part hingedly connected to one of the end panels and foldable relative thereto into engagement with the other of the end panels, said part being adapted to be fastened to said other end panel.
Claim 12
Dependent Claim 32 words
A blank according to claim 8, wherein said closure members comprise dust flaps and closure flaps disposed outwardly of the longitudinally extending fold lines hingedly connected to the ends of the panels.
Claim 13
Dependent Claim 19 words
A blank according to claim 8, wherein the panels having the concave edges are divided medially by hinge lines.
Claim 14
Dependent Claim 20 words
A carton blank according to claim 8, folded on fold lines medially of the panels having the concave side edges.
