Provided is a double-walled container (1), which includes an outer layer body (2) and an inner layer body (3). A single adhesive strip (4) is disposed between the outer layer body (2) and the inner layer body (3) in a manner such that the adhesive strip (4) extends along a center axis (C). The outer layer body (2) is provided with a single ambient air introduction hole (2d). The outer layer body (2) includes an inner surface, which is configured by a separation surface (2f) and a pseudo-adhesive surface (2g). The separation surface (2f) faces the ambient air introduction hole (2d) and is separated from an outer surface of the inner layer body (3), and the pseudo-adhesive surface (2g) faces the separation surface (2f) and is separably adhered to the outer surface of the inner layer body (3).

An insulating container can be configured to retain a volume of liquid, and include a first inner wall having a first end having an opening extending into an internal reservoir, and a second outer wall forming an outer shell. The opening can be sealed by a closure, the closure having an upper portion with a handle that has a circular curvature equal to the cylindrical portion of the closure. The closure may also have a lower portion that is joined to the upper portion by an injection molded polymer element. The closure may also be in the form of “flip” type of closure such that the lid can be selectably opened or closed by the user by rotating a flip closure into either the opened or closed position. The closure may also be a two-part lid having a lower cap that may be configured to be removably-coupled to the container and an upper cap that may be configured to be removably-coupled to the lower cap.

A bottle, or a generic container, for the tight storage of diverse materials, may comprise a circular lip at the top of its neck finish or opening with an inferiorly disposed smooth, slanted and curved outer surface that is punctuated by equally spaced indentations and that may extend outwards and stepwise downwards, first through a vertical and then a convex surface and finally to a smooth surface on which may be disposed a button protrusion. A tightly sealed finish may be characterized by its lip and the equally spaced protruding lugs disposed on its inner surface interacting tightly with threading and other parts of the inner part of a reusable aggregate cap which, in turn, may inextricably couple with an outer part on whose outer annular flange surface may be disposed a button marker protrusion that, because of inaccessible features and mechanisms on the cap units, may only align with the one on the outer surface of the finish or opening of an unopened bottle or container. Determination of whether a tightly capped container has been previously opened or tampered with, may quickly be performed, either visually or through touch, by checking the alignment, or not, of the externally exposed button protrusions.

Containers for storing food in a storage compartment may include a base portion of the container. The storage compartment is sealed with a film to get the food stored in the storage compartment fresh. The container further includes a reversible lid that is able to attach to the base portion of the container in two different configurations. In a first configuration the reversible lid attaches to the base portion without affecting the seal created by the film. In a second configuration the reversible lid attaches to the base portion when the lid is inverted and the film is removed from the base portion.

A closure assembly (100) for a container (200) is provided. The closure assembly (100) includes a frame (105) configured to couple to a container (200); an interior lid hingedly coupled to the frame (105) along a first longitudinal side thereof and movable between a closed position and an open position, wherein the lid (110) includes a lid rim that defines an opening, a flexible membrane (300) housed within the opening of the lid rim, wherein the flexible membrane (300) defines a zone configured to permit a plurality of articles to feed therethrough, and a tab member (120) fixedly coupled to the lid rim and extending above the membrane (300), wherein the tab member (120) defines a channel groove (125) configured to receive a leading article of the plurality of articles therein and separate the leading article from the plurality of articles. The assembly further includes a cover panel (150) hingedly coupled to the frame (105) along the first longitudinal side thereof and movable between an assembly closed position and an assembly open position.

A lid for a container holding a flowable contents comprising a first section brim mount member, unitarily molded and reversibly securely sealed onto an upper end rim of a container forming a raised ring-shaped crown portion with two opposing drinking access ports, circumscribing a second elevated recessed planar region forming a recessed centrally configured hatch opening in the top wall. A second section hatch cover member is unitarily molded, sized and shaped to concentrically fit over, and reversibly securely seal the recessed hatch opening in a co-planar configuration. The hatch cover member is securely and reversibly joined in a non-permanent manner to the top wall of the brim mount member via a ball and socket-type hinge pivoting the hatch cover member quickly and reliably about an axis line parallel to the top wall of the brim mount member rotatably between a closed position and an opened position.
