Abstract
Abstract A container in the form of a scoop having front, rear and end wall panels hingedly connected together at arcuate score lines defining convex side edges for the end wall panels and concave side edges for the front and rear wall panels, a bottom hingedly connected to at least two of the wall panels, and an open top, the carton being erected by squeezing together the end wall panels with the fingers of one hand. The carton erects with a ''''snap'''' and stays erect without pushing up from the bottom, stands erect before or after filling or when partly empty, and can be conveniently erected and used for the ''''scooping'''' of materials thereinto in the same motion and using a single hand.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
187 words
A carton comprising a front wall panel, a rear wall panel, and a pair of end wall panels hingedly connected together at arcuate score lines defining complementary convex and concave side edges of adjacent panels, said end wall panels having bisecting folding score lines provided therein permitting said carton to be folded flat, an open top, and a bottom panel hingedly connected to the lower edges of said front and rear wall panels, but unconnected to the lower edges of said end wall panels, wherein the side edges of said end wall panels are arcuately convex and the side edges of said front and rear wall panels are arcuately concave, whereby said carton may be snapped from flat folded position into open position by squeezing the end wall panels thereof with the fingers of one hand and whereby said carton remains in said open position with said end wall panels curved arcuately concave outwardly, the bottom of said carton bulging downwardly and having a bottom plane not lower than the lower edges of said end wall panels so as to provide stability of said carton upon standing.
Claim 2
Dependent Claim
187 words
A carton comprising a front wall panel, a rear wall panel, and a pair of end wall panels hingedly connected together at arcuate score lines defining complementary convex and concave side edges of adjacent panels, said end wall panels having bisecting folding score lines provided therein permitting said carton to be folded flat, an open top, and a bottom panel hingedly connected to the lower edges of said front and rear wall panels, but unconnected to the lower edges of said end wall panels, wherein the side edges of said end wall panels are arcuately convex and the side edges of said front and rear wall panels are arcuately concave, whereby said carton may be snapped from flat folded position into open position by squeezing the end wall panels thereof with the fingers of one hand and whereby said carton remains in said open position with said end wall panels curved arcuately concave outwardly, the bottom of said carton bulging downwardly and having a bottom plane not lower than the lower edges of said end wall panels so as to provide stability of said carton upon standing.
