Abstract
Containers, and sheets for forming containers, having bottom locking features, and related methods. In some embodiments, two opposing bottom panels of a sheet may be configured to define at least a portion of a bottom wall of a container. One such bottom panel may comprise a locking tab and the other such bottom panel may comprise a locking aperture configured to receive the locking tab. In a finished configuration, the locking tab may extend at least substantially parallel to the bottom panels within the locking aperture, and the locking tab and locking aperture may be spaced apart from the side walls of the container in the finished configuration.
Claims20
A sheet for folding into a container, comprising:
- a first bottom panel configured to define at least a portion of a bottom wall of a container,
- wherein the container in a finished configuration comprises a first side, a second side, a third side opposite from the first side, and a fourth side opposite from the second side,
- wherein the first bottom panel is configured to extend from the first side towards the third side in the finished configuration, and
- wherein the first bottom panel comprises a locking tab;
- a second bottom panel configured to define at least a portion of the bottom wall of the container,
- wherein the second bottom panel is configured to extend from the second side towards the fourth side in the finished configuration;
- a third bottom panel configured to define at least a portion of the bottom wall of the container,
- wherein the third bottom panel is configured to extend from the third side towards the first side in the finished configuration,
- wherein the third bottom panel comprises a locking aperture configured to receive the locking tab,
- wherein, in the finished configuration, the locking tab extends at least substantially parallel to the third bottom panel within the locking aperture, and
- wherein the locking tab and the locking aperture are configured to increase an amount of force on the bottom wall required to unfold panels defining the bottom wall;
- wherein the locking aperture comprises a length extending between the first side and the third side in the finished configuration, wherein the locking aperture comprises a width extending between the second side and the fourth side in the finished configuration, wherein the locking tab comprises a width extending between the second side and the fourth side in the finished configuration, wherein the locking tab comprises a length extending between the first side and the third side in the finished configuration, wherein the length of the locking tab is less than the length of the locking aperture, and wherein the width of the locking tab is greater than the width of the locking aperture;
- and
- a fourth bottom panel configured to define at least a portion of the bottom wall of the container,
- wherein the fourth bottom panel is configured to extend from the fourth side towards the second side in the finished configuration.
12 more elements
A container, comprising:
- a bottom wall defined by at least a first bottom panel and a second bottom panel, wherein the first bottom panel comprises:
- a first edge foldably coupled to a first side panel;
- a second edge opposite from the first edge;
- and
- a locking tab positioned adjacent to the second edge,
- and wherein the second bottom panel comprises:
- a first edge foldably coupled to a second side panel;
- a second edge opposite from the first edge;
- and
- a locking aperture configured to receive the locking tab from the first bottom panel, wherein the locking aperture is spaced apart from the first edge of the second bottom panel, wherein the locking aperture is spaced apart from the second edge of the second bottom panel,
- wherein the locking aperture further comprises a slot extending from one side of the locking aperture, and wherein the slot is configured to receive a user's finger during assembly of the container to allow the locking tab to be pulled or pushed through the locking aperture with a single finger.
8 more elements
A method for folding a sheet into a container, comprising:
- folding each of a plurality of side panels to create an open container structure;
- folding a first bottom panel relative to an adjacent first side panel to define at least a portion of a bottom wall of the container, wherein the first bottom panel comprises a locking tab;
- folding a second bottom panel relative to an adjacent second side panel to overlap with the first bottom panel and define at least a portion of the bottom wall of the container, wherein the second bottom panel comprises a locking aperture;
- and
- inserting the locking tab into the locking aperture such that the locking tab engages the locking aperture to lock the first bottom panel in place relative to the second bottom panel, wherein the locking tab is engaged with the locking aperture at a location spaced apart from planes defined by each of the plurality of side panels, wherein the step of inserting the locking tab into the locking aperture comprises:
- positioning the locking tab adjacent to the locking aperture;
- inserting a finger into a slot positioned at one end of the locking aperture;
- and
- pulling the locking tab through the locking aperture.
