Abstract
A self-erecting container 20 has a removable section 32 adjacent the engaging panels of a self-erecting end structure, and a permanent web which supports the self-erecting structure notwithstanding separation of the removable panel. A front side wall panel 24 has a removable section 32 at an end of the container adjacent the self-erecting structure 42, 44, 54, 56. A flap panel 44 is attached at least initially to the removable section 32. An end panel 56 adjacent the flat panel 44 has a back-folded tab 62 fixed to the flap panel 44 by a permanently attached web 60, maintaining the structural integrity of the self-erecting container bottom when removable section 32 is separated from front side wall panel 24.
Claims20
A self-erecting container, comprising:
- a plurality of sidewall panels foldably attached to one another along corners of the container, one of the sidewall panels being a front sidewall panel having a removable section at an end of the container;
- a plurality of end panels foldably attached to respective ones of the sidewall panels at said end of the container, the end panels folding up when the container is erected and holding the sidewall panels apart to define an inner volume of the container, one of the end panels being a flap panel attached to said removable section of said front sidewall panel, and an adjacent one of the end panels being a bellows fold panel, the bellows fold panel having a back-folded tab fixed to the flap panel such that the flap panel and the bellows fold panel rest over one another when the container is erected, the end panels drawing one another open when the sidewall panels are folded apart;
- and,
- a permanently attached web disposed between the bellows fold panel and the flap panel adjacent the removable section, whereby the flap panel remains fixed to the container when the removable section is separated from said front sidewall panel.
An improved self-erecting container of the kind having a plurality of sidewall panels foldably attached to one another along corners of the container, one of the sidewall panels being a front sidewall panel, a plurality of end panels foldably attached to respective ones of the sidewall panels at said end of the container, the end panels folding inwardly when the container is erected and holding the sidewall panels apart to define an inner volume of the container, the end panels including a pair of flap panels attached to a first pair of opposite sidewall panels and a pair of bellows fold panels attached to a second pair of opposite sidewall panels, the improvement comprising:
- the front sidewall panel having a removable section at an end of the container adjacent the end panels, the removable section being separable from the front sidewall panel;
- one of the flap panels being attached at least initially to the removable section, an adjacent one of the end panels being a bellows fold panel having a back-folded tab fixed to the flap panel such that the flap panel and the bellows fold panel rest over one another when the container is erected, and the end panels draw one another open when the sidewall panels are folded apart;
- and,
- a permanently attached web disposed between the bellows fold panel and the flap panel adjacent the removable section, whereby the flap panel remains fixed to the container when the removable section is separated from said front sidewall panel.
