A storage container includes a body, a lid, and two handles. The body defines a compartment between first and second side walls of the body. The compartment is accessible along a top end of the body. The first and second side walls include respective cavities that are recessed from exterior surfaces of the side walls via rims that define perimeters of the cavities. The lid is connected to the top end of the body and encloses the compartment when in a closed position. The two handles are tethered to the body via cords, and are configured to nest within the cavities of the corresponding side walls when not grasped by a person. First and second ends of the handles are configured to engage opposing portions of the corresponding rim to retain the handle nested in the cavity via an interference fit.

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.

A negative pressure storage container includes a container cover, a container body, a rotary device, a gear transmission mechanism and a vacuum pump so arranged that rotating the rotary device drives a driving gear of a transmission gear set of the gear transmission mechanism to rotate an eccentric wheel, causing a link to reciprocate a reciprocating piston of a vacuum pump in creating a negative pressure in the container body. When the negative pressure reaches a certain level, the bottom wall of a plastic inner cover member of the container cover is forced to curve and to carry the driving gear away from the rotary device; at this time, and thus, the rotary device runs idle at this time, preventing overloading the transmission gear set and prolonging the service life of the gear transmission mechanism.

A drywall mud dispenser closure system includes a drywall mud applicator having an access opening therein. A closure assembly is removably positioned over the access opening and closes the access opening to inhibit air from entering the access opening.

Systems, methods and apparatuses for covering a storage compartment of a receptacle, reducing exposure of items inside the receptacle to the surrounding environment and decreasing the risk of damage or undesirable impacts on the products being transported. The covered receptacle systems, methods and apparatuses not only provide a physical barrier over the exposed opening of the receptacle's storage compartment, but further passively facilitate the removal of the environmental hazards from the receptacle cover, leading the environmental hazard in a direction away from the receptacle. The removal of environmental hazards may be performed by directing the hazard in a direction away from the storage compartment of the receptacle via a downwardly sloping top surface of the receptacle cover.

A spill proof denture container for protecting a denture from environment pollution and microorganisms is provided. The spill proof denture container includes a lid with internal threads in the inner side, a lower portion with external threads, and a retractable strainer with holes. The lid is adapted to open and close the spill proof denture container. The internal threads of the lid screw over the external threads of the lower portion to close the spill proof denture container. The retractable strainer includes a handle to withdraw from or place back the retractable strainer to the lower portion of the spill proof denture container. When the retractable strainer is removed out from the lower portion, the tiny holes allow proper drainage of liquid from the retractable strainer to the lower portion of the spill proof denture container.

A lid for a beverage cup includes a mouth opening, an aroma opening, and a concentrator member. The mouth opening is positioned closer to a rim of the lid than the aroma opening. An area of the aroma opening is greater than an area of the mouth opening. The concentrator member surrounds the aroma opening and extends from a plane formed by the aroma opening to a height above the aroma opening. A cross sectional area of the concentrator decreases in a direction from a base to an upper end of the concentrator, creating a concentration of beverage aromas in the space surrounding a user's nose. The concentrator channels a concentrated amount of aroma to the nose, providing an enhanced drinking and tasting experience.

A wig storage assembly includes a plurality of boxes that is each structured to define an interior storage area to contain a wig. The plurality of boxes is stackable on top of each other having each of the plurality of boxes being removably attached together to facilitate a plurality of the wigs to be simultaneously transported. A plurality of screens is each releasably attachable to a respective one of the plurality of boxes to retain the wig in the interior storage area of the respective box. A plurality of dividers is each insertable into the interior storage area defined in a respective one of the plurality of boxes for dividing the interior storage area of the respective box. A lid is removably attachable to a topmost one of the plurality of boxes when the plurality of boxes is stacked for carrying the stack of plurality of boxes.

A 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.
