A container is provided. The container has a lid and a tray. The lid has a contiguous array of walls extending therefrom. The tray has a recess for receiving soft food material. The recess is sized to receive the array of walls of the lid. The tray has a contiguous array of ridges corresponding to the array of walls of the lid. A top surface of the ridges of the tray contact a bottom surface of the walls of the lid when mated to form sealed compartments. A sealing mechanism is provided along a perimeter of at least one of the lid and the tray sealing the lid and the tray along perimeters thereof, and restricting separation of the bottom surface of the walls of the lid from the top surface of the ridges of the tray when mated. At least one of the lid and the tray is formed from a flexible material so that the lid and the tray can be partially separated to remove a food portion formed in one of the compartments without breaking all of the seals of the compartments.

The present invention provides a method of collecting a liquid sample using a leak proof, air tight plastic container device. The method comprises placing the sample in the container device, the device comprised of a container, a lid, a lid groove containing a gasket therein which covers and tightens over the rim of the container, a lid flange, and a thin hook in the container containing a second gasket compressed by the lid flange when the lid is closed over the container; and sealing the sample in the container device by engaging the internal screw threads of the lid with the external screw threads of the container and rotating the lid until resistance to rotation is encountered. The method further comprises transporting the sample to a site for analysis, whereby no leakage of the liquid sample and no air seepage into or out of the container occur during transport.

A container, preferably for loosely stored products, including a) a container body including a peripheral body wall; b) a cover including an outer peripheral cover wall and a cover skirt; c) a hinge connecting the container body and the cover, and d) at least one protruding element provided on an peripheral body wall of the container and/or on an outer peripheral cover wall.

A lid includes: a brim sealing channel at a periphery of the lid; an outer sipping sidewall positioned within a circumference of the brim sealing channel and extending above the brim sealing channel; a sipping topwall adjacent to the outer sipping sidewall; a sipping port in the sipping topwall; and a central recess within the circumference of the brim sealing channel and proximate to the sipping topwall, wherein the central recess has an overhang and a bottomwall; and a rotatable closure tab includes: a central portion; a flanged-shaped structure at a first side of the central portion; a tab sidewall supported by the flanged-shaped structure; a tab topwall extending outwardly from the tab sidewall and away from the flanged-shaped structure; a sealing depression in the tab topwall; and a retention rim extending radially from the central portion and positioned between the overhang and bottomwall of the central recess.

A synthetic resin cup container including two members: a cup body having a cylindrical shape and a bottom disposed at a lower end of a round peripheral sidewall of this cup body, and a flange unit including a fitting cylinder and a brim-like flange, an inner edge portion of the flange being integrally connected to an upper end of the fitting cylinder, wherein the flange unit is detachably fitted in an upper portion of the cup body by fitting the fitting cylinder in an upper portion of the peripheral sidewall.

An airtight container for storing comestibles and other articles is disclosed that includes a bottom container portion having a bottom seal section, a top container portion having a top seal section, the top seal section engaged with the bottom seal section to form a container seal at a circular interface, an opening in the top portion, the opening recessed from an outer surface of the top portion and a lid door movably secured to the top portion in which the lid door is configured to selectively engage the opening to form an access seal and in which the top container portion is configured to promote laminar flow across the top portion outer surface.

A mechanism or feature incorporated into or on the lid of a one piece child-resistant container which allows customization of the container by attachment of an independent, separate ancillary piece or identifier cap to the lid. The identifier cap may snap onto or be pushed onto the lid in a secure manner.

The present invention provides an improved, leak proof, air tight, cost-effective, plastic liquid specimen container device and methods of use, comprised of a container, a lid, a lid groove containing a gasket therein that is configured to cover and tighten over the rim of the container, a lid flange, and a thin hook in the container containing a second gasket that is compressed by the lid flange when the lid is closed over the container. The improved container device of the present invention thus provides two, independent, internal seals that protect the liquid contents therein for extended periods of time, even if the plastic undergoes deformation, during transport, especially air transport, and under varying temperature and atmospheric pressure.

The packaging box in the disclosure, which is a packaging box for packaging an object, includes a tubular box body having a first opening in an upper surface thereof, and a lid body detachably attached to the first opening to cover the first opening. The box body has a first turned-back section that is provided in at least one part of a peripheral edge of the first opening and turned back so as to be overlapped with an inner surface of the box body. The lid body has an insertion section that is provided in at least one part of a peripheral edge of the lid body and is to be inserted between the first turned-back section and the inner surface of the box body when the lid body is attached to the first opening.
