Abstract
Abstract A scoop made of a single paperboard blank. A back wall, with a transverse slot, is folded upward. Two side portions, with rear tabs, are folded upward and the rear tabs are folded inward behind the back wall. The top of the back wall is folded down causing the corners of the rear tabs to extend through the slot. Thus, the scoop is locked into its assembled position. A flexible container may be provided as a receptacle for the offensive materials and the soiled scoop.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
198 words
A scoop, made of a single paperboard blank, comprising: a central portion, which has a bottom wall and a back wall, with a first transverse crease separating the bottom wall from the back wall, said back wall having a top portion and a second transverse crease for allowing the top portion to be folded downward, and said back wall having a slot extending partially along the second transverse crease; a side portion, separated from the central portion by a longitudinal crease, said side portion having a side wall and a rear tab, said rear tab having a top corner, with a third transverse crease separating the side wall from the rear tab, and said longitudinal crease being slit along the edge of the rear tab; such that when the back wall is folded up along the first transverse crease, the side portion is folded up along the longitudinal crease, the rear tab is folded inward along the third transverse crease, and the back wall is folded downward along the second transverse crease, then the top corner of the rear tab will partially project through the slot in the back wall thereby locking the scoop into an assembled position.
Claim 2
Dependent Claim
198 words
A scoop, made of a single paperboard blank, comprising: a central portion, which has a bottom wall and a back wall, with a first transverse crease separating the bottom wall from the back wall, said back wall having a top portion and a second transverse crease for allowing the top portion to be folded downward, and said back wall having a slot extending partially along the second transverse crease; a side portion, separated from the central portion by a longitudinal crease, said side portion having a side wall and a rear tab, said rear tab having a top corner, with a third transverse crease separating the side wall from the rear tab, and said longitudinal crease being slit along the edge of the rear tab; such that when the back wall is folded up along the first transverse crease, the side portion is folded up along the longitudinal crease, the rear tab is folded inward along the third transverse crease, and the back wall is folded downward along the second transverse crease, then the top corner of the rear tab will partially project through the slot in the back wall thereby locking the scoop into an assembled position.
Claim 3
Dependent Claim
29 words
The scoop of claim 1 further comprising: a second side portion, similar in structure to the first side portion, attached to the central portion opposite the first side portion.
Claim 4
Dependent Claim
82 words
The scoop of claim 2 wherein the paperboard blank is of a rectangular cofiguration, wherein the longitudinal creases converge toward the rear end of the blank, wherein the first and second transverse creases are parallel to the front end of the cardboard blank, and wherein the acute angle formed between each longitudinal crease and each third transverse crease is approximately equal to the acute angle between each longitudinal crease and the first transverse crease, both of these angles being less then 90°.
Claim 5
Dependent Claim
37 words
The invention of claim 3 wherein the first transverse crease intersects the third transverse crease of each side portion at the same point where the longitudinal crease of each side portion intersects its associated third transverse crease.
Claim 6
Dependent Claim
14 words
The invention of claim 4 wherein each acute angle is between 81° and 87°.
Claim 7
Dependent Claim
57 words
The scoop of claims 1, 2, 3, 4 or 5 in combination with a flexible container, such that the scoop may be used to pick up refuse and to deposit the refuse in the container, and then the soiled paperboard scoop may be deposited in the container and everything may be disposed of in a sanitary manner.
