Abstract
A collapsible paperboard container and a blank for constructing the same. The container has a bottom wall with a peripheral wall extending upwardly therefrom. A plurality of score lines are provided in the peripheral wall which facilitate movement of this wall from an expanded position to a collapsed position in response to a manual force being applied thereto to cause a first portion of the wall to move toward a second portion thereof. Visual indicators are provided on the container to identify to the consumer where and how to apply manual force to the peripheral wall.
Claims37
A collapsible paperboard container comprising:
- a bottom wall;
- a peripheral wall which is connected at a bottom end to the bottom wall and extends upwardly therefrom, and which has expanded and collapsed positions;
- an interior chamber defined by the bottom wall and peripheral wall;
- a top entrance opening of the interior chamber defined by a top of the peripheral wall;
- a plurality of score lines formed in the peripheral wall which facilitate movement of the peripheral wall from the expanded position to the collapsed position in response to a manual force being applied to the peripheral wall to cause a first portion thereof to move toward a second portion thereof;
- and
- a visual indicator on the container suggestive of a need to apply the manual force.
An improved blank for forming a gable-top paperboard container, wherein the blank is a substantially rectangular sheet of paperboard having a longitudinal axis and a horizontal axis with opposing first and second edges disposed substantially parallel to the horizontal axis and first and second ends disposed substantially parallel to the longitudinal axis;
- wherein said blank further includes three longitudinally oriented, spaced apart fold lines stamped into the sheet and extending between the first and second edges, said fold lines dividing the sheet into four longitudinal panels disposed in a side-by-side horizontal arrangement;
- and four horizontally oriented fold lines extending between the first and second ends, wherein a first horizontal fold line is disposed proximate the first end and a second fold line is disposed proximate the second end;
- and a third fold line is disposed spaced approximately one quarter of the distance between the first and second ends and adjacent the first fold line;
- and a fourth fold line is disposed approximately one quarter of the distance between the first and second ends and adjacent the second fold line;
- and wherein the improvement comprises:
- a plurality of score lines stamped into the sheet at locations other than on the fold lines, said score lines being provided as lines of weakness to effect collapse of a container produced using the blank upon application of manual force;
- and
- a plurality of visual indicators provided on a front surface of the blank suggestive of areas where manual force should be applied in order to effect collapse of the container.
