A container that seals in a volume of material is provided. The container may be routinely opened, closed and material may be removed or added. A removable plate and a base define a maximum volume available for material when the container is sealed. A screen may be disposed between the plate and the base. The screen may optionally be comprised within the base, adhered to the base, or removable from the base. Features for enabling manipulation of the plate and/or screen are optionally provided.

A reusable container housing. The housing includes a hollow shell that receives a recyclable cup, e.g., filled with powdered detergent, and holds it sealed and secure. A lid of the housing, when placed on top of the shell to seal its top opening, causes the cup within to be pressed downward past a set of detents and locked thereby. The hollow shell includes an open bottom sealed with a flexible diaphragm. To eject the cup from the housing (e.g., when it is empty), the lid is removed, and the flexible diaphragm is pushed upward thereby forcing the cup upward and past the detents. The cup may then be removed and replaced.

The present invention relates to a beverage container structure, which mainly makes a container upper part and a container lower part dock with each other, and weld and combine at the butt joints to form a container body. In addition, the liquid outlet of the container upper part is screwed and assembled with a cover body to seal the beverage in the container body, so as to prevent the beverage from being poured out during transportation or storage. Furthermore, when users would like to drink a beverage, the cover body can be opened only by exerting force to rotate the cover body, and the cover body can still be closed when drinking at a time is not finished, so as to improve the hygiene and convenience of beverage drinking.

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.

A plug for a pouch assembly, where 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.

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.

An apparatus is provided in the form of a neck for a plastic bottle or other plastic container. The neck includes an external thread with a constant major diameter that can engage with a bottle cap with an internal thread. The neck has an internal surface with an irregular shape where the internal diameter proximate to the top sealing surface is greater than the internal diameter proximate to the side wall of the plastic bottle. The internal surface of the neck engages with a fitment inserted into the neck of the plastic container to prevent movement of the fitment.

A plug for a pouch assembly. The plug is 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.

Provided is a sealing cap including: a body having a cylindrical part and a sealing part; an annular part having the inner diameter larger than the outer diameter of the cylindrical part; a first coupling part coupling the cylindrical part and the annular part to each other at a first coupling position; and a second coupling part coupling the cylindrical part and the annular part to each other at a second coupling position. A pair of first grooves are formed in the cylindrical part, a pair of second grooves are formed in the sealing part so as to extend in a second direction and interpose an axis, the pair of first grooves are connected to the pair of second grooves, the first coupling position is a position interposed between the pair of first grooves, and the second coupling position is another position not interposed between the pair of first grooves.

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.
