A composite container lid comprising an inner plug 1 with a flow-out port and an upper lid 3 detachably attached to a container mouth portion 80, wherein the inner plug 1 includes an upper lid engaging cylinder 5, a container mouth portion-securing member 7 having a circumferential wall 9 that surrounds the upper lid engaging cylinder 5, and linking pieces 11 that link the inner surface of the circumferential wall 9 to the upper lid engaging cylinder 5 so as to form a flow-out port 13; the upper lid engaging cylinder 5 is provided, on the upper end portion of the outer surface thereof, with a circumferential protuberance 5a for temporary engagement; engaging pieces 37 are formed on the inner surface of a top plate 31 of the upper lid 3, the engaging pieces 37 having an undercut 37a for temporarily engaging with the circumferential protuberance 5a that temporary engages with the upper lid engaging cylinder; and a sound-suppressing protrusion 50 is provided in a region surrounded by the engaging pieces 37.

Disclosed are caps for closing an opening in a lid for a container, such as a paint can or bucket, wherein the caps comprises top walls comprising on their top surfaces centrally disposed recesses configured to receive a tool to rotate the caps; and threaded cylindrical projections on their bottom surfaces.

A closure system for closing a container opening is disclosed that includes a stopper member, a cage member for mounting to a container, a cover member reversibly mountable to the cage member, and an integrity visualization member. The stopper member has a plug portion to fit into the container opening and a cover portion to abut a boundary surface of the container opening. The plug portion of the stopper member is fitted into the opening of the container and the cage member is mounted to the container. The cage member applies a force to the cover portion to push the cover portion onto the boundary surface of the container opening. The cover member covers an aperture of the cage member when mounted to the cage member. The integrity visualization member indicates an integrity of the closure system and is positioned between the cover portion and the cage member.

Systems and methods for storing a liquid include a container including a body portion defining an internal chamber and at least one opening in communication with the internal chamber, and an insertable plug including a plug body with two rings attached to the plug body via hinges, the insertable plug configured to be inserted into the opening so that a portion of the plug body covers a lip of the opening to restrict access through the opening to the liquid contained in the internal chamber, wherein the hinges can be deformed to raise the two rings away from the plug body. An insertable plug for a container can include a cylindrical plug body, and two rings attached to the plug body by hinges, wherein the hinges can bend to orient the rings towards or away from the plug body.

A mug cap apparatus for brew-through comprising a cylindrical body having a primary hallow opening in the center and at least one cylindrical body attaching tab formed around the cylindrical body; the cylindrical body attaching tab formed a recess; a secondary opening positioned in the cylindrical body and within the recess; a first lid having a blade edge for ease of opening and a sealer that seals the secondary opening when the first lid is in closed configuration; the first lid further comprises at least one attachment point; a second lid having at least one second lid attaching tab wherein the second lid attaching tab comprises at least one first attachment point to the first lid and at least one second attachment point to the cylindrical body attaching tab; where the first attachment point and the second attachment point are positioned in linear space apart along the edge of the cylindrical body attaching tab; wherein the first attachment point is positioned in proximity to the center of the hallow opening and the second attachment point is positioned in proximity to the edge of the hallow opening; wherein the second lid further comprises a sealer that seals the primary hallow opening when in closed configuration; wherein in lifting the first lid in open configuration will result in lifting the second lid.

A plug for a pouch assembly, wherein the plug includes a top wall, an inner axial skirt and an outer axial skirt. The inner axial skirt depends from the top wall in a direction opposite the top wall. The inner axial skirt includes an inner surface, an outer surface, an upper end and a lower end. The outer axial skirt includes an inner surface and an outer surface, an upper end proximate the top wall and a lower end spaced apart therefrom. A seal bead is positioned on the inner surface of the outer axial skirt spaced apart from the upper end. The seal bead extends inwardly toward the inner axial skirt. The plug is attachable to the spout of the pouch. The seal bead is structurally configured to hermetically seal against the spout, while precluding sealed engagement between the inner axial skirt and the spout.

An apparatus for securing a vessel includes a primary cap having a threaded portion that is configured to selectively engage corresponding threads of a vessel to secure the primary cap to the vessel, and at least one projection. The apparatus further includes a removable secondary cap configured to engage the primary cap to secure the vessel, the secondary cap including at least one lug, the lug having a shear zone that contacts the projection when the primary and secondary caps are engaged and secured to a vessel. When the secondary cap is removed from the primary cap, the shear zone is broken by the projection such that the secondary cap cannot by reinstalled on the primary cap.

A tamper indicating closure cap or overseal comprises a top wall, and an annular top wall skirt attached to a periphery of the top wall. A locking member is attached to the top wall skirt so as to be movable between: i) a first position projecting inwardly with respect to the top wall for application of the closure cap or overseal to a container opening and/or to a container closure plug and ii) a second position projecting inwardly and upwardly towards the top wall, thereby to lock the closure cap or overseal to the container closure and/or closure plug.

A liquid-containing combination container includes a first container that contains a liquid and that has oxygen permeability, a second container that contains the first container and that has an oxygen barrier property, and an oxygen absorber that absorbs oxygen in the second container. Pressure in the first container is 1 atm or less.
