A storage device has a container and a lid dolly that is usable as a lid to close the container and as a dolly to transport the container, wherein the lid dolly has casters configured to fit within the interior of the container when the lid dolly is closed on the container. A storage device kit has a container, a lid, a template, casters and fasteners. A retrofit kit for a storage device with a container and a lid has a template, casters and fasteners. The template may be installed as a reinforcement plate to structurally reinforce the lid for supporting the weight load of the container and its contents.

The invention relates to a device for at least one of storing and transporting a plurality of packaging containers comprises a tub-shaped lower part and an upper part for closing the lower part in a closed position in which they enclose an interior of the device. The lower part has a bottom and a lower-part wall projecting from the bottom in the direction of the upper part. The lower part comprises a wall element which with the lower-part wall forms a circumferential wall of the lower part. The wall element is movable relative to the lower part in order to at least partially open the wall.

A cover for a container, comprising a central web comprising a first web part and a second web part; and a hinge pivotally connecting the first and second web parts; wherein a first one of the web parts comprises at least one rib on an edge thereof facing the hinge, and a second one of the web parts comprises at least one corresponding recess on an edge thereof facing the hinge.

A storage box that includes a container and a lid, which includes a bottom plate, a top plate, a top plate anchor and a movable latch. The bottom plate includes an arm that the height of its left section is bigger than the height of its right section, and its inclined middle section inclines from left to right. The movable latch includes a protrusion that its left section is flat and the inclined right section inclines and descends from left to right. The movable latch is designed to be positioned between the top plate and the bottom plate, in a way that the horizontal protrusion is inserted under the horizontal arm of the bottom plate and the movable latch can be moved from right to left and back.

A package has a tray slidably mounted in a carton. The carton has a front access port and at least one catch. The tray has a pair of stops positioned to successively engage at least one catch in order to restrict outward movement of the tray. The tray can be positioned with the pair of stops located inwardly of, and locked in place by, at least one catch. The catch on the carton can be manipulated to clear one of the pair of stops and allow it to move outwardly past the catch.

A document box includes a top container portion and a bottom container portion. The top container portion has a rear wall with a hollow rib integrally disposed thereon. The bottom container portion is rotatably coupled to the top container portion about an axis of rotation, and the top container portion is positionable between a closed position and an open position on the bottom container portion. The bottom container portion having a rear wall and a bottom wall. A raised member is positioned on the bottom wall adjacent to the rear wall. The top container portion where rotated to the open position releasably positions the raised member within the hollow recessed rib, thereby defining a hold open feature for the top container portion.

A tamper evident closure includes a first snap, a cover, a tear strip connected to the cover, and a second snap connected to the tear strip. In a closed position, a cavity of the cover is configured to be placed over the first snap, and the second snap is configured to be placed in and engaged with a cavity in the first snap. In a closed position, there is a gap between the first snap and the cover.

A packaging, especially for food, including a cardboard shell and a cover placed thereon in the closed state and which engages over the outside of an upper edge of the shell. Inwardly protruding nubs arranged at at least two opposing side walls of the cover interact with retaining elements at associated side walls of the shell. The side walls having the retaining elements each have a wall portion which is connected to the bottom of the shell by a bend, a first reinforcing portion connected to the upper end of the wall portion by a bend, a second reinforcing portion connected to the first reinforcing portion by a bend and an adhesive-secured portion connected to the second reinforcing portion by a bend and which is adhesively bonded to the outer side of the wall portion. A sub-portion of the wall portion that lies above the adhesive-secured portion, and the first and second reinforcing portions delimit a triangular channel. The retaining elements are formed by edges of openings in or by downwardly directed outer surfaces of the second reinforcing portions.

This disclosure provides a box lid and an airtight box and belongs to the technical field of food preservation boxes. The box lid comprises: a lid body; and a sealing ring connected to the lid body, the sealing ring comprising an inclined portion inclined inwards, wherein the inclined portion can produce elastic deformation and is deformable to a sealing state. The beneficial effects of this disclosure are as follows: The specially designed sealing ring allows the airtight box to maintain an airtight effect when the interior is in a positive pressure environment, so the airtight box does not need air release after being sealed. When the box lid reaches the sealing position from the contact position, the air pressure in the box increases to assist the inclined portion of the sealing ring to achieve sealing.
