Abstract
Abstract A box or carton having a compact closed product storage position which is easily unfolded into an enlarged tray or pan position with hinged side wall portions providing struts to maintain the opened pan or tray position and to serve as a gate providing access to the interior of the tray or pan. In the closed position, the box or carton is a small six-sided, sealed package preferably housing a bag of absorbent ground clay. In the open tray or pan position, the box or carton has a flat bottom and relatively high side and end walls so that when the clay is spread over the bottom, it will provide a bed or substantially less thickness than the height of the side and end walls and serving as a commode for small house pets, such as cats and the like.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
361 words
A carton having a compact six-sided closed storage position and an enlarged open pan use position formed from a flat rectangular blank of carton forming board having four substantially equally spaced transverse score lines and two longitudinal score lines inwardly from and parallel to the side edges of the blank defining five substantially equal width centrAl panels and a row of end panels of the same width on both sides of the central panels, the middle end panels having outer end portions cut longitudinally parallel to the side edges thereof a substantial distance inwardly from said edges along the entire length of each middle end panel and cut transversely inward from said side edges to the adjacent longitudinal cut at one end of each middle end panel to provide rectangular flaps hinged to adjacent end panels by the transverse score lines between the end panels, the portions of each middle end panel inwardly from said flaps having score lines diverging from the midpoint of the outer edge thereof to the intersections of the transverse score lines thereof with the adjacent longitudinal score line dividing each said portion into three triangular sections, cuts separating the corner end panels from the adjacent central end panels, the corner end panels underlapping the adjacent outer central panels and affixed thereto, the flaps turned inwardly, the triangular sections being folded over each other and the central panel sections wrapped to form the closed six-sided carton whereby when said carton is unwrapped from said closed position the middle three of said five central panels provide the bottom for the pan, the two end panels of said five central panels provide vertical end walls of the pan, the middle three of said rows of end panels provide side walls of the pan, each flap when swung to the same plane as the side wall on which it is hinged forming a strut holding the carton in the open pan position and when swung out of said plane providing a low level doorway into the pan, and said panels of substantially equal width providing the pan with a volume about three times the volume of the closed six-sided carton.

Dependent Claim
361 words
A carton having a compact six-sided closed storage position and an enlarged open pan use position formed from a flat rectangular blank of carton forming board having four substantially equally spaced transverse score lines and two longitudinal score lines inwardly from and parallel to the side edges of the blank defining five substantially equal width centrAl panels and a row of end panels of the same width on both sides of the central panels, the middle end panels having outer end portions cut longitudinally parallel to the side edges thereof a substantial distance inwardly from said edges along the entire length of each middle end panel and cut transversely inward from said side edges to the adjacent longitudinal cut at one end of each middle end panel to provide rectangular flaps hinged to adjacent end panels by the transverse score lines between the end panels, the portions of each middle end panel inwardly from said flaps having score lines diverging from the midpoint of the outer edge thereof to the intersections of the transverse score lines thereof with the adjacent longitudinal score line dividing each said portion into three triangular sections, cuts separating the corner end panels from the adjacent central end panels, the corner end panels underlapping the adjacent outer central panels and affixed thereto, the flaps turned inwardly, the triangular sections being folded over each other and the central panel sections wrapped to form the closed six-sided carton whereby when said carton is unwrapped from said closed position the middle three of said five central panels provide the bottom for the pan, the two end panels of said five central panels provide vertical end walls of the pan, the middle three of said rows of end panels provide side walls of the pan, each flap when swung to the same plane as the side wall on which it is hinged forming a strut holding the carton in the open pan position and when swung out of said plane providing a low level doorway into the pan, and said panels of substantially equal width providing the pan with a volume about three times the volume of the closed six-sided carton.
Claim 3
Dependent Claim
23 words
The carton of claim 1 wherein said flaps provide doorways reducing the height of the side walls of the pan by about one-half.
Claim 4
Dependent Claim
59 words
The carton of claim 1 wherein the outer edges of the outer central panels and the outer edges of the middle three end panels have tabs projecting therefrom, score lines between the tabs and panels, and said tabs being turned on said score lines into the pan to form downwardly opening gutters trapping discharge of material from the pan.
Claim 5
Dependent Claim
76 words
The carton of claim 1 having at least one bag of absorbent clay material therein of a capacity to hold two pre-allocated controlled portions of clay with each portion being sufficient to form a bed covering the bottom of the pan and with the entire content of the bag being insufficient to cover the bottom of the pan to a height of more than about one-third of the height of the side walls of the pan.
Claim 6
Dependent Claim
53 words
The carton of claim 3 wherein the tabs on the outer end edges of the central panels have end edges mating with adjacent end edges on the tabs of the adjacent end panels in the open pan position of the carton to provide a continuous inturned rim around the top of the pan.
Claim 7
Dependent Claim
115 words
A carton having a compact closed flat sided tube position with hinged rectangular central flaps disposed on side walls thereof, said flaps having a height less than that of said side walls, and projecting into the carton into abutting relation with each other from opposite side walls of the carton, said carton being unfolded into an enlarged four-sided open top pan with said flaps selectively acting as struts by abutting their free end edge against an adjacent side wall edge to hold the carton in open pan position and said flaps being swingable from the strut positions thereof to provide doorways in the side walls of the pan giving low level access to the pan.
Claim 8
Dependent Claim
115 words
A carton having a compact closed flat sided tube position with hinged rectangular central flaps disposed on side walls thereof, said flaps having a height less than that of said side walls, and projecting into the carton into abutting relation with each other from opposite side walls of the carton, said carton being unfolded into an enlarged four-sided open top pan with said flaps selectively acting as struts by abutting their free end edge against an adjacent side wall edge to hold the carton in open pan position and said flaps being swingable from the strut positions thereof to provide doorways in the side walls of the pan giving low level access to the pan.
Claim 9
Dependent Claim
