Abstract
A plastic storage container with wheel assemblies having an axle pin rotatably fixed to the container, a secure lid latch having a double-wall construction to ease opening and closing as well as an offset hinge to allow protection of the latch during distribution, and an internal tray having dependent flanges which mate to the storage container to prevent the walls of the storage container from splaying.
Claims13
A plastic storage container assembly comprising:
- an open-top box;
- a lid for covering the top of the box, said lid having a locking ridge;
- and
- a latch having a detent configured for engaging the locking ridge to releasably secure said lid to said box, said latch being hinged to said box and opening into a recess within a wall of said box to reduce handling damage to said latch during transport, the latch detent being entirely recessed within the recess when the latch is fully opened and remote from the recess when the latch is engaged with the locking ridge.
A plastic storage container assembly comprising:
- an open-top box having a bottom and a side extending upward from the bottom, the side having an upper edge;
- a lid for covering the top of the box;
- and
- a latch for releasably securing said lid to said box, said latch being hinged to said box and being pivotable into a recess within the side of said box to permit the storage container to be nested within a like storage container having a bottom below the subject storage container such that the latch extends below the upper edge of the side of the lower, like storage container to capture and protect said latch.
A plastic storage container assembly comprising:
- a box comprising a bottom, an open top opposite the bottom and two opposing sides, said box having a length and a width;
- and
- a tray within the box, said tray having first and second lateral dimensions extending parallel to the top of the box, the first lateral dimension being substantially equivalent to the width of said box, said tray being suspended above the bottom of said box, and being slidable within and engageable with the sides of said box to prevent the sides of the box from substantially displacing relative to one another.
A plastic storage container assembly comprising:
- a box comprising a bottom and two opposing sides, said box having a length and a width;
- a tray within the box, said tray having first and second lateral dimensions, the first lateral dimension being substantially equivalent to the width of said box, said tray being suspended above the bottom of said box, and being slidable within and engageable with the sides of said box to prevent the sides of the box from substantially displacing relative to one another;
- a flange extending laterally from the periphery of said tray;
- a ledge integral with the sides of said box upon which the tray flange rests;
- a rib extending vertically downward from the flange;
- and
- a rail extending vertically upward from the sides of said box, the rib and rail being interengaged to prevent the sides of said box from moving relative to each other.
A plastic storage container assembly comprising:
- a box comprising a bottom and two opposing sides, said box having a length and a width;
- a tray within the box, said tray having first and second lateral dimensions, the first lateral dimension being substantially equivalent to the width of said box, said tray being suspended above the bottom of said box, and being slidable within and engageable with the sides of said box to prevent the sides of the box from substantially displacing relative to one another;
- a rib extending vertically downward from said tray;
- and
- a rail extending vertically upward from the sides of said box, the rib and rail being interengaged to prevent the sides from moving relative to each other.
A plastic storage container assembly comprising:
- a box comprising a bottom and two opposing sides, said box having a length and a width;
- a tray within the box, said tray having first and second lateral dimensions, the first lateral dimension being substantially equivalent to the width of said box, said tray being suspended above the bottom of said box, and being slidable within and engageable with the sides of said box to prevent the sides of the box from substantially displacing relative to one another;
- a rib extending vertically downward from said tray;
- and
- a track formed within the opposing sides of the box, the rib and track being interengaged to prevent the sides from moving relative to each other.
A plastic storage container assembly comprising:
- an open-top box;
- a lid for covering the top of the box, said lid having a locking ridge, the lid including a spacer extending below the locking ridge;
- and
- a latch for releasably securing said lid to said box, said latch being hinged to said box,
- said latch having a first plate with a detent depending therefrom for releasable engagement with the locking ridge, and a second plate over the detent for gripping said latch while opening, the first and second plates being coextensive, said first plate being flexible relative to said second plate to allow relative motion between the second plate and detent upon opening and closing said latch, the latch including a flange spaced from the detent, the flange being positioned to engage the lid spacer upon closing the latch to bias the latch detent toward the lid locking ridge.
A nestable plastic storage container assembly comprising:
- a box having a bottom, an open top surrounded by a rim, and a set of aide walls defining a storage area within the box, each one of the side walls thereby having an interior and an exterior face relative to the box;
- a lid for covering the open top of the box;
- a pair of ears extending outwardly from an upper region of the exterior face of one of the side walls, the same side wall also having a recess in its exterior face under the pair of ears and each of the pair of ears having a bottom;
- a latch hingedly attached to the pair of ears and moveable between a first position remote from the recess for engaging the lid and a second position within the recess for protection of the latch in storage;
- and
- the pair of ears disposed so that their bottoms rest on a rim of a second nestable plastic storage assembly when nested with same, and the latch, when in the second position and nested with the second nestable plastic storage assembly, is enclosed therein.
