Abstract: A method for unlatching a latch on a container includes providing a lifting arm for lifting a latched container. Moving the latched container from a first position to a second position with the lifting arm and unlatching the container by flexing the latch on the container by moving the container from the first position to the second position. The latch includes a first member which is pivotably mounted to a lid. A second member is adapted to selectively engage a projection on a body of the container. An arch member connects the first member to the second member and a handle extends in the direction opposite to the direction in which the arch member extends. The step of deflecting the handle is by movement of the moving member to the flex the latch.

Abstract: A wheel for mounting to an axle of a wheeled product, the wheel comprising an axle receiving bore extending from a front wall to a rear wall of the wheel; the axle receiving bore comprising at least one finger integral with the wheel and extending towards the front wall of the wheel, the finger comprising a detent facing inwardly into the axle receiving bore, the finger being adapted to be flexed from an insertion position to a locking position and from a locking position into an unlocking position, the finger being flexed outwards in the insertion position as the axle is inserted within the axle receiving bore, and the finger being flexed inwards to insert the detent into a notch of the axle once the axle is inserted in the axle receiving bore in the locking position; and the finger being flexed outwards thereby disengaging the detent from the notch in the unlocking position.

Abstract: A cart has a container body and a lid rotatably affixed to the container body so as to be selectively rotated between an open position and a closed position. A latch has a first end adapted to be rotatably affixed to the lid. A second end is adapted to engage the container body. The first end is connected to the second end by an arched member, the arched member is capable of flexure when a force is applied at a concave surface of the arched member.

Abstract: A collapsible poultry crate comprising a base defining a peripheral edge; a plurality of side walls, each side wall being mounted on the base along a respective portion of the peripheral edge for pivoting movement relative to the base each side wall pivoting between a closed position and an open position; each side wall having a respective top surface, two or more tabs extending from a respective top surface of the side walls; and a plurality of end walls, each end wall being mounted on the base along a respective portion of the peripheral edge for pivoting movement relative to the base; the base having a width and a length such that M poultry crates arranged in a predetermined pattern exhibit a footprint substantially the same as the footprint of N meat crates disposed in a predetermined pattern.

Abstract: A system for unlatching a latched container includes a body. A lid is rotatably affixed to the body and movable between a first position and a second position. A latch is pivotably mounted on the lid for selectively locking the lid in the closed position, the latch having a first member adapted to be pivotably mounted to the lid and a second member adapted to selectively engage a projection on the housing. An arched member connects the first member to the second member. A lifting arm has a proximal end, adapted to be affixed to a truck, and distal end. A container manipulating assembly is affixed to the arm at the distal end. The container manipulating assembly includes a grabber member for engaging a container disposed therein. A moving member moves between a first position and a second position, the moving member unlatching the container by moving from the first position to the second position when the lifting arm moves the container.

Abstract: A wheel assembly for mounting to an axle of a wheeled product includes a wheel having an opening and a locking element which is insertable in the opening to secure the wheel to the axle. The locking element has a portion engaging the wheel and a second flexible portion for releasably engaging the axle. The locking element is so constructed as to allow a tool to be inserted therethrough for releasing engagement between the wheel assembly from the axle.

Abstract: A collapsible container that comprises first and second sidewalls and first and second end walls pivotally connected to a base. The first sidewall includes at least one latching member that cooperates with a latching member of the first end wall to secure the first sidewall and the first end wall together when the first sidewall and the first end wall are in upright positions. The container also includes a wall locking system that has a plurality of locking members on the first sidewall and at least one locking member on the first end wall. The locking member on the first end wall cooperates with the locking members on the first sidewall to prevent the first sidewall from moving relative to the first end wall in at least one direction when the first sidewall and first end wall are in upright positions. The container further includes a wall alignment system that has a first member extending from one of the sidewalls, and a second member that extends from one of the end walls.

Abstract: A container lid has a top wall with a series of recessed areas that include therewithin a plurality of geometrical projections and a bottom wall that displays a plurality of recesses complementary in shape to the projections of the top wall whereby identically shaped lids may be stacked or cross-stacked in nested condition with the projections of one lid being received in the corresponding recesses of a superposed lid. The lid is adapted to be affixed to a container having four side pieces and a bottom piece, the configuration of the lid allowing a stacking or cross-stacking arrangement of lid-covered containers with their side pieces in the erected position as well as the stacking or cross-stacking of lid-covered containers with their side pieces in an inwardly folded position.
