Abstract

A flat, folded carton having a snap-up bottom for erection into a generally conical hollow container includes a bottom panel of generally octagonal configuration, and two upstanding side wall panels interconnected by end walls. One side panel is of isosceles trapezoidal shape, while the other side panel is of isosceles triangular shape. The end walls are hingedly connected to the isosceles triangular wall panel, and bonded by a glue strip to the isosceles trapezoidal panel. The resulting container configuration is generally conical, with the planes of the side wall panels extending upwardly and divergently from the bottom panel. Hence, the carton provides an enlarged bell mouth opening for the generally conical hollow container, thereby facilitating the scooping and loading of products into the container.

Claims

1. A flat folded, snap-up bottom type container capable of being erected into a generally hollow, conical configuration having an enlarged bell-mouth opening, comprising:

a generally elongate, polygonally shaped bottom panel forming one end of said container and having a pair of intersecting score lines therein;

first and second opposed side panels respectively hingedly connected to opposite elongate edges of said bottom panel and extending upwardly away from the latter toward the other end of said container,

said second side panel including a pair of opposed lateral edges converging toward each other in a direction away from said bottom panel to form a generally isosceles triangularly shaped configuration having the base thereof adjacent said bottom panel and the vertex thereof adjacent said other end of said container,

said first side panel including a pair of opposed lateral edges diverging away from each other in a direction toward said other end of said container to form a generally isosceles triangularly shaped configuration having the base thereof adjacent said other end of said container and the vertex thereof adjacent said bottom panel,

said first and second panels being geometrically inverted with respect to each other whereby to form said enlarged bell-mouth opening; and

a pair of end panels respectively hingedly connected both to said first and second side panels for enclosing the sides of the container.

2. The container of claim 1, wherein said end panels each comprise a first and second portion divided by a score line and extending in respective planes oblique to each other, each of said first portions being generally triangular in shape and having one edge thereof hingedly connected to the corresponding converging lateral edge of said second side panel.

3. The container of claim 2, wherein said vertex of said second side panel is truncated by edge portions thereof extending oblique to each of said converging lateral edges thereof, and said first portions of each of said end panels includes an arcuate edge extending away from the corresponding second portion and toward said second side panel, said arcuate edge registering with said edge portions of said second side panel and at least partially defining said enlarged, bell mouth opening of said container.

4. The container of claim 1, including a pair of glue strips respectively hingedly connected along one edge of said second portions of said end panels, said glue strips overlapping exterior surface areas of said first side panel and secured to the latter.

5. A blank comprising a single sheet of paperstock for forming the container of claim 1.

6. A blank comprising a single sheet of paperstock for forming the container of claim 2.

7. A blank comprising a single sheet of paperstock for forming the container of claim 3.

8. A blank comprising a single sheet of paperstock for forming the container of claim 4.
