A cover configured to cover an opening of a tray or container is provided. The cover may include a main panel and a pair of side panels, each side panel extending from opposing edges of the main panel. Each side panel may include an intermediate panel connected to the main panel by a fold line, and a side flap connected to the intermediate panel by a hinge line. The intermediate panel is at least partially secured to a bottom surface of the main panel. The side flap is configured to rotate away from the bottom surface of the main panel. A slot is formed between the side flap of the side panel and the bottom surface of the main panel. The slot is configured to receive an upper portion of the tray or container when the cover is positioned on the tray or container.

A preload mechanism for a memory alloy wire actuator is disclosed that includes a rotating element configured to rotate about a pivot. The rotating element has a first contact point that is configured to couple to the memory alloy wire actuator such that contraction of the memory alloy wire actuator displaces the first contact point such that the rotating element rotates from a first position to a second position. The preload mechanism also includes a bias element with a first end that is coupled to a second contact point of the rotating element and a second end configured to be pinned relative to the pivot. The bias element has a line of action extending from the second end through the first end. The line of action has an offset distance that is the minimum distance between the line of action and the pivot. The offset distance has a first value when the rotating element is in the first position and a second value when the rotating element is the second position, the second value being smaller than the first value.

A packaging system includes box parts connected to one another by a latch assembly. A method is used for installing the box parts with the latch assembly in a packaging assembly.

A household tissue paper container includes a container body that is configured to store household tissue paper therein and has a take-out portion having an outlet through which the household tissue paper is taken out; and an open/close lid that is pivotably attached to the container body and closes the outlet. The outlet is formed at a swelling portion having a substantially spherical raised shape in the take-out portion. The outlet has a protruding piece that is protruding from a front edge of the outlet toward a rear where the open/close lid is attached to the container body.

A lid and a combination of a tub and the lid, the lid comprising a web and a circumferential skirt depending thereon; wherein the skirt comprises at least one tab, a first retention tooth and a second retention tooth, the first retention tooth being molded on an inner surface of the tab; and wherein for positioning the lid in a first closed position on the tub, the first and the second retention teeth are engaged under a top lip of the tub by applying a pressure on the lid; when first opening the tub once the lid is in the first closed position, the tab is broken free from the skirt into a position of the tab in which the tab remains pivotably attached to the skirt, and the tab is pulled, causing disengagement of the first retention tooth from under the top lip of the tub, the second retention tooth acting as a pivoting axis for the lid.

An example storage chest is provided. The example storage chest may include a box portion and a lid. The box portion may include a front wall, a rear wall, and a floor attached to the front and rear walls to form a primary compartment for storage of items. The lid may include a front panel, a rear panel, and a top panel attached to the front a rear panels. The rear panel may be pivotably coupled to the rear wall of the box portion. The front panel, the rear panel, and the top panel may define a secondary compartment within the lid for storage of items. The secondary compartment may include a lid storage compartment comprising a hingedly affixed door.

The present application provides a storage box lid, a storage box and a method for manufacturing the same. The storage box lid comprises a flexible thin film and a plastic rigid frame. The flexible thin film is prepared from a two-component platinum contented liquid silicone. In the present invention, the storage box, formed by using the storage box lid with the flexible thin film, in combination with a matching box body, can significantly improve the capacity for storing food, so that it can effectively store food larger than the box body. Moreover, the storage box of the present invention does not significantly squeeze the stored food, and the effect is distinctive.

The present invention discloses a box, comprising: a box body; a box cover, wherein the box cover is covered at an opening of the box body, a limiting cylinder is formed on the bottom end of the box cover near an outer edge, and the bottom end of the box cover is provided with an annular clamping groove located at the outer side of the limiting cylinder; an elastic sealing ring which comprises: a top sealing ring, an inserting flange; a middle sealing cylinder, and the middle sealing cylinder is sleeved on the outer cylinder wall of the limiting cylinder; and a bottom sealing ring, and the outer edge of the bottom sealing ring is in compression sealing contact with the inner wall of the box body.

In an embodiment, the invention comprises a container apparatus with a lateral stability rail system. At least one rail extends within the lid portion and at least one track extends through the base portion. The rail terminates in a tooth and the track terminates in a pocket. When the container is in a hingedly closed position, the at least one rail nests within the at least one track and the at least one tooth nests within the at least one pocket.

A storage container comprised of a container bottom, and with multiple sealable covers, configured to connect the covers to the container bottom in both open and closed arrangements. Additionally, each of said covers will seal to the container bottom, and each of said covers will seal to an opposing cover. The containers may be proportioned to stack or nest into other open containers, as well as on top of containers with closed covers. The containers may also allow open covers to rest vertically alongside the container without significantly contacting the surface the container is resting on.
