A container cover for storage container includes a rotary device, an outer cover member, an inner cover member, a first guide block, second guide block, a pumping piston and a piston seat so arranged that when the rotary device is driven by a user to rotate the first guide block, guide rods of the first guide block are moved along a first continuous wave-shaped track of the second guide block, causing the second guide block and the pumping piston to move alternatively up and to further pump air out of the storage container through an air-pimping hole of the piston seat to create a negative pressure. Further, a first spring member an upper rail seat can be provided to balance the movement of the pumping piston and to stabilize the rotation of the first and second guide blocks. A relief valve rod can be selectively used for giving a visual indication indicative of the presence of a negative pressure in the storage container.

A dual swing lid mechanism includes a base section and a lid openable and closable with respect to the base section. The lid includes a lid main body section, an arm section, a first supporting shaft, and a second supporting shaft. The lid main body section has a lock mechanism including a first rod engageable with the arm section and a second rod engageable with the base section. The lid changes among a closed state; a first opened state of opening a containing section with the first supporting shaft as a center; and a second opened state of opening the containing section with the second supporting shaft as the center. The first rod engages with the arm section in the closed state and the first opened state and disengages from the arm section in the second opened state. The second rod engages with the base section in the closed state and the second opened state and disengages from the base section in the first opened state.

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.

A container and a cover having a sealing structure includes: the container including a bottom and a side wall having one end connected to the bottom to form a space, and another end of the side wall that is not connected to the bottom is an open end, the side wall having an inner surface and an outer surface, the inner surface faces the space, and the inner surface has a first hook portion; and the cover disposed at the open end of the container, the cover has a covering portion and a second hook portion, the covering portion covers the open end, and the second hook portion is hooked on the first hook portion. The covering portion tightly covers the open end, and the second hook portion is hooked to the first hook portion, so that the coupling between the cover and the container is more stable.

A holding tool is configured to efficiently and reliably enable a close contact between a container and a lid with a simple mechanism and a simple operation. The holding tool is configured to be used together with a container and a lid for the container to sandwich the container and the lid. The holding tool includes a base on which the container is placed, and a cover configured to cover the lid. The base and the cover each have an opening at a central portion and are configured to engage with each other to press and sandwich the container and the lid upward and downward.

A multi-compartment container system includes a plurality of compartments. Each compartment includes a cup portion comprising a volume adapted to hold a food or liquid, and a frame portion joined to the cup portion. The frame portion surrounds a top portion or edge of the cup portion, and includes a connector element disposed on a side of the frame and one or more first mating elements. The compartment also includes a lid having one or more second mating elements adapted to engage with the one or more first mating elements of the frame to form a seal, and a chamber adapted to hold a utensil. The connector element of the frame is joined to an adjacent connector element of an adjacent frame of an adjacent compartment. The cup portion includes a first section and a second section, and the cup portion is adapted to move between an expanded state in which no part of the second section is inside the first section and a collapsed state in which at least a portion of the second section is inside the first section.

A lid assembly outfits a liquid container and may function to position a liquid-permeable container relative to the liquid container. The lid assembly may include a lid body having a rim-receiving groove, an object-supportive depression or container support feature, and a primary liquid-letting aperture. The primary liquid-letting aperture primarily enables liquid egression from the liquid container thereby supporting certain lid body-based beverage service methodology, including the steps of supporting a liquid permeable container by the object-supportive depression or container support feature thereby forming a lid-container ensemble, and outfitting the liquid container with the lid-container ensemble. The liquid permeable container contains liquid permeable media and after being outfitted upon the liquid container via the lid body, liquid is directed into the liquid permeable container and through the liquid-permeable media for forming media-permeated, flavor-infused liquid. The flavor-infused liquid is then outlet into the liquid container for providing a contained beverage for consumption.

A liquid saving device having a container, a lid for attaching to the container, the lid having a top side and a bottom side, a finger element attached to the lid, and a closure for covering the top side of the lid. The liquid saving device also having an inner cover for covering the bottom side of the lid.
