| 229155000 | Plural extensions mechanically interlocked with each other | 7 |
| 20090072017 | BOX FLAP LOCKING SYSTEM - The invention provides a foldable box design having a box flap locking system, comprising: a first flap having an edge with a generally trapezoidal shaped tab cut therein, wherein said generally trapezoidal shaped tab is defined by two inwardly projecting grooves; and a second flap that locks with the first flap, wherein the second flap includes an edge with a second generally trapezoidal shaped tab cut therein, and wherein said second generally trapezoidal shaped tab is defined by two outwardly projecting grooves. | 03-19-2009 |
| 20110192891 | APPARATUS AND SYSTEM FOR A SELF-ATTACHING CONTAINER - A support mechanism for a container includes a container coupling mechanism, a flap overlap mechanism and an attachment mechanism. The container coupling mechanism is configured to couple to a distal end of a first flap of the container. The flap overlap mechanism is configured to overlap a second flap of the container when the first flap and the second flap are in a closed position, such that the second flap is between an interior portion of the container and the flap overlap mechanism in the closed position. The attachment mechanism is configured to selectively maintain the first flap and the second flap in the closed position. The support mechanism supports a greater force applied in a direction normal to a plane formed by the first flap and second flap in the closed position than a force supported by the first flap and the second flap without the support mechanism. | 08-11-2011 |
| 20130032632 | SHIPPING CONTAINER - A shipping container has a lid locked using pressure, rather than friction. The container includes front and rear side panels and a lid. The lid has a positive locking tab for engaging with a slot in the front side panel. The tab has a greater length than the slot. An end of the tab and an edge of the lid form a notch therebetween. In an embodiment, a corrugated paperboard blank is folded to approximate the lid to the front side panel. The lid is folded along an angled score line, rotating the tab with respect to the slot so that an end of the tab engages the slot and the front panel at an end of the slot engages the notch. The lid is folded to rotate the tab in the opposite direction; the tab then engages with the slot, the end of the tab extending beyond the slot. | 02-07-2013 |
| 20140263600 | Reclosable and Stackable Food Tray and Tray Blank - Disclosed are reclosable and stackable food trays formed from a single blank that are capable of being folded and glued on standard machinery. Embodiments of the invention include raised gussets that extend beyond the top edge of the side panels of the formed tray and beyond the top of the formed tray. In some embodiments, the raised gussets help prevent distortion in all dimensions and facilitate the stacking of multiple trays on top of one another such that the stacked trays cannot slide off the lower tray. | 09-18-2014 |
| 20160137336 | Carton With Reinforcement Features - A carton for holding a plurality of articles. The carton includes at least one top panel, a first side panel, a second side panel, and a bottom panel. A plurality of end flaps is foldably connected to a respective panel to close an end of the carton. The carton includes reinforcement features at the end of the carton to increase the strength of the carton. | 05-19-2016 |
| 229156000 | One extension interlocks with at least two others | 2 |
| 20090261152 | CONTAINER WITH FOLDING LID - A folding closure that is foldable to a closed orientation having a pair of gabled lid sections oriented to be linearly aligned and abutting one another in an end-to-end relationship and a pair of lateral lid sections oriented to be linearly aligned with one another and abutting opposite sides of the gabled lid sections. | 10-22-2009 |
| 20090261153 | INSULATING SLEEVE FOR CONTAINERS - A container having a sidewall, a folding closure, and a sleeve each formed from a one-piece blank. Also disclosed is a sleeve configuration having a plurality off vents and spacers for locating the vents in a spaced apart orientation relative to a container sidewall. | 10-22-2009 |
