Abstract
Abstract A container for picking up, enclosing, transporting and disposing materials is provided. Such principal material is pet waste. The container is of tray shape comprising two hinged integral face panels disposed in a coextensive planar position in the open condition and in an angular position in the closed condition. In the open position the two hinged panels form a tray surrounded by side and edge panels. The side panels are interrupted at the hinge by triangular webs with the apex of each web at the intersection of the hinge and the side panel. The container is actuated from its stable open traylike condition through a metastable condition to a stable closed triangular clamshell-like configuration. The transition from the open to closed condition is powered by the energy of the folding webs inverting their relative position with respect to their integral sides. The box is formed of resilient sheet materials such as cardboard, polymeric resins and the like, preferably of a biodegradable nature.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
283 words
A container comprising: a pair of generally similarly dimensioned face panels each having an inner edge joined to and forming a hinge line with the inner edge of the other panel, an outer edge generally parallel to and spaced from said line, and a pair of generally parallel side edges each extending between the respective inner and outer edges; a pair of normally generally parallel side panels extending transversely from each of said face panels, each from a respective side edge of the respective face panel; an end panel extending transversely from each of said outer edges in the same direction as said side panels and generally fixed relative to the side panels of the respective face panel, said face panels being relatively foldable at said line without folding any of the other panels between a stable open position with said face panels generally co-planar and said end panels spaced from each other and a stable closed position with said face panels at an acute angle to each other, said end panels generally meeting, and said side panels overlapping and generally parallel to one another; and a web at each end of said hinge line and having a pair of nonparallel edges joined to the respective side panels, said webs and panels being stiff and uncreased but limitedly deformable and said webs moving with limited nonpermanent deformation of themselves and of said side panels from a position transverse to said line and parallel to said side edges through a position generally parallel to said line into a reversed position transverse to said line, sandwiched between and parallel to said side panels on displacement of said face panels between said open and closed positions.
Claim 2
Dependent Claim
283 words
A container comprising: a pair of generally similarly dimensioned face panels each having an inner edge joined to and forming a hinge line with the inner edge of the other panel, an outer edge generally parallel to and spaced from said line, and a pair of generally parallel side edges each extending between the respective inner and outer edges; a pair of normally generally parallel side panels extending transversely from each of said face panels, each from a respective side edge of the respective face panel; an end panel extending transversely from each of said outer edges in the same direction as said side panels and generally fixed relative to the side panels of the respective face panel, said face panels being relatively foldable at said line without folding any of the other panels between a stable open position with said face panels generally co-planar and said end panels spaced from each other and a stable closed position with said face panels at an acute angle to each other, said end panels generally meeting, and said side panels overlapping and generally parallel to one another; and a web at each end of said hinge line and having a pair of nonparallel edges joined to the respective side panels, said webs and panels being stiff and uncreased but limitedly deformable and said webs moving with limited nonpermanent deformation of themselves and of said side panels from a position transverse to said line and parallel to said side edges through a position generally parallel to said line into a reversed position transverse to said line, sandwiched between and parallel to said side panels on displacement of said face panels between said open and closed positions.
Claim 3
Dependent Claim
29 words
The container defined in claim 1 wherein one of said face panels is slightly wider in a direction perpendicular to said line than the other of said face panels.
Claim 4
Dependent Claim
49 words
The container defined in claim 2 wherein said end panel of said one face panel is also slightly wider in a direction perpendicular to said line than the other of said end panels, whereby said end panels can overlap and limitedly fit within each other in said closed position.
Claim 5
Dependent Claim
26 words
The container defined in claim 1 wherein said webs are each generally triangular and each have an apex at the respective end of said hinge line.
Claim 6
Dependent Claim
25 words
The container defined in claim 4 wherein said side panels are generally shaped as right trapezoids and said face and end panels are generally rectangular.
Claim 7
Dependent Claim
15 words
The container defined in claim 1 wherein said face and end panels are generally rectangular.
Claim 8
Dependent Claim
22 words
The container defined in claim 1 wherein said end panels have serrated toothed-edges generally parallel to but opposite the respective outer edges.
Claim 9
Dependent Claim
27 words
The container defined in claim 1, further comprising means for urging said outer edges together and thereby displacing said container from said open into said closed position.
Claim 10
Dependent Claim
18 words
The container defined in claim 8 wherein said means includes a finger loop attachable at said hinge line.
Claim 11
Dependent Claim
34 words
The container defined in claim 8 wherein said means includes a wand, a gripper engageable with said outer edges, and means for remotely displacing said gripper for urging said outer edges toward each other.
