Abstract
Abstract A package comprising an integral tray and separable tool or paddle for delivering material components from one depression of the tray to another and for subsequently mixing them prior to their use. It is designed for storing component materials in a multiple component system, such as a thermosetting resin system. Material is accurately transferred from one depression to the other by the associated tool. The interior surfaces of the depressions are complementary to the configuration of the intersecting edges of the tool or paddle.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
143 words
A tray for storage and mixing of individual material components, said tray comprising: an upwardly open container bounded by side and end edges and including two or more depressions located within its edges, said depressions being adapted to respectively store individual material components for subsequent mixing with one another; a flat paddle having intersecting edges along its periphery, said paddle being integrally formed as part of the container along one of its edges and being detachable from the container along said one edge by a joining line of weakness; one of said depressions having a cross-sectional configuration complementary to the configuration of the intersecting edges of the paddle; whereby material within said one depression can be removed from it by a continuous movement of the paddle through the depression while said intersecting edges thereof engage the cross-sectional configuration of said depression complementary thereto.
Claim 2
Dependent Claim
143 words
A tray for storage and mixing of individual material components, said tray comprising: an upwardly open container bounded by side and end edges and including two or more depressions located within its edges, said depressions being adapted to respectively store individual material components for subsequent mixing with one another; a flat paddle having intersecting edges along its periphery, said paddle being integrally formed as part of the container along one of its edges and being detachable from the container along said one edge by a joining line of weakness; one of said depressions having a cross-sectional configuration complementary to the configuration of the intersecting edges of the paddle; whereby material within said one depression can be removed from it by a continuous movement of the paddle through the depression while said intersecting edges thereof engage the cross-sectional configuration of said depression complementary thereto.
Claim 3
Dependent Claim
28 words
A tray as claimed by claim 1 wherein a second of said depressions also has a cross-sectional configuration complementary to the configuration of intersecting edges of the paddle.
Claim 4
Dependent Claim
156 words
A tray for storage and mixing of individual material components, said tray comprising: an upwardly open container bounded by side and end edges and including two or more depressions located within its edges, said depressions being adapted to respectively store individual material components for subsequent mixing with one another; a flat rectangular paddle having opposed planar surfaces bounded by four side edges intersecting one another at four corners along its periphery, said paddle being integrally formed as part of the container along one of its edges and being detachable from the container along said one edge by a joining line of weakness; one of said depressions having a cross-sectional configuration complementary to the configuration of the intersecting edges of the paddle; whereby material within said one depression can be removed from it by a continuous movement of the paddle through the depression, while said intersecting edges thereof engage the cross-sectional configuration of said depression complementary thereto.
Claim 5
Dependent Claim
156 words
A tray for storage and mixing of individual material components, said tray comprising: an upwardly open container bounded by side and end edges and including two or more depressions located within its edges, said depressions being adapted to respectively store individual material components for subsequent mixing with one another; a flat rectangular paddle having opposed planar surfaces bounded by four side edges intersecting one another at four corners along its periphery, said paddle being integrally formed as part of the container along one of its edges and being detachable from the container along said one edge by a joining line of weakness; one of said depressions having a cross-sectional configuration complementary to the configuration of the intersecting edges of the paddle; whereby material within said one depression can be removed from it by a continuous movement of the paddle through the depression, while said intersecting edges thereof engage the cross-sectional configuration of said depression complementary thereto.
Claim 6
Dependent Claim
54 words
A tray as claimed in claim 3 wherein the individual depressions are bounded by a planar upper surface extending between them in an integral unit; said one depression having an upwardly facing ramp intersecting the upper surface along a periphery having two opposed corners, each corner being complementary to one corner of the paddle.
Claim 7
Dependent Claim
107 words
A tray as claimed in claim 3 wherein the individual depressions are bounded by a planar upper surface extending between them in an integral unit; said one depression having an upwardly facing ramp intersecting the upper surface along a periphery having two opposed corners, each corner being complementary to one corner of the paddle, said ramp having a surface configuration complementary to the locus of the intersecting edges of said one corner of the paddle when pivoted about an axis in the plane of the upper surface between a substantially horizontal position fitted into one of said opposed corners to a position perpendicular to said upper surface.
Claim 8
Dependent Claim
62 words
A tray as claimed in claim 3 wherein said one depression is bounded by a planar upper surface; said one depression having an upwardly facing ramp with a surface configuration complementary to the locus of the intersecting edges of the paddle when fitted into the depression and moved along the ramp while held in a position substantially perpendicular to said upper surface.
