A refill for dispensing a volatile material includes a bottle having a body defined by at least one sidewall and a neck extending from the body. The neck includes a rim at an upper end thereof and has an inner surface, a top surface, and an outer surface. A wick has a first end positioned within the bottle and a second end extending out of the bottle. A plug assembly is secured to the neck of the bottle and retains the wick within the bottle. A cap is coupled with the neck of the bottle. An underside of the cap includes a stop and a flange that form a seal with the plug assembly when the refill is in an assembled configuration.

The invention is directed to a closure (1) having a base (3) with a top deck (4) and a therewith adjacent skirt (5) extending in an axial direction (z) comprising an internal thread (6). The closure (1) is comprising a sealing arrangement (16) with an inner seal (18) extending in the axial direction (z) from the top deck (4). The inner seal (18) is having an inner annular sealing surface (29) arranged radially inward with respect to an outer seal (17) and pointing in an outward direction. The sealing arrangement further comprises an outer seal (17), which in its cross-section comprises a base section (20) extending in the axial direction (z) from the top deck (4) and an end section (21), which is bend inwardly with respect to the course of the base section (20) in the direction of the inner seal (18) and which terminates in a sealing surface (22) pointing in an inward direction.

A closure includes a polymeric top wall portion, a polymeric annular skirt portion, a polymeric continuous plug seal and a polymeric top seal. The annular skirt portion depends from the polymeric top wall portion. The annular skirt portion includes an internal thread formation for mating engagement with an external thread formation of a container. The polymeric annular skirt portion includes an interior surface and an exterior surface. The plug seal depends from the polymeric top wall portion. The continuous plug seal is spaced from the interior surface of the polymeric annular skirt portion. The top seal includes sealing gussets integrally connected thereto. The top seal and the sealing gussets depend from the polymeric top wall portion. The top seal and sealing gussets are located between and spaced from the plug seal and the annular skirt portion.

A cap assembly for a container has an inner sleeve that is secured to the neck of the container and an outer cap that is adjustably secured to the inner sleeve. The outer cap can be adjusted downwardly relative to the inner sleeve so that a gap between the bottom of the outer cap and a top of the container can be minimized or eliminated.

A method for providing pre-assembled and sterilized container closure assemblies that are each adapted to be secured onto a container including manufacturing pre-assembled container closure assemblies each adapted to be secured onto a container, injection molding a monolithic spout body of thermoplastic material, injection molding a manually removable rotational cap, securing the cap onto the neck of the spout body in a closed position of the cap, submerging each of the pre-assembled container closure assemblies in a bath of sterilizing liquid, and removing the container closure assemblies from the bath of sterilizing liquid, and allowing the sterilizing liquid to drain. A pre-assembled container closure assembly adapted to be secured onto a container is also disclosed.

A closure may have a top wall and a side wall depending from the top wall. A plug seal device may depend from said top wall within the side wall. The plug seal device may have an upper section, a lower section, and a sealing section proximate the boundary between the upper section and the lower section. The sealing section is operable such that when the plug seal device is inserted in an opening to an inner cavity in a container, the sealing section engages with an inner container surface to provide a seal between an inner cavity of the container and the external environment.

A closure includes a top panel and a corner section connecting an outer periphery of the top panel with a downwardly extending annular skirt. A plurality of gently curved ridges are spaced about the outer perimeter of the closure. The ridges generally extend from a lower portion of the skirt and around the corner section, with the upper ends of the ridges terminating proximate the top panel outer periphery. A plurality of knurls extend radially outwards from the midpoints of the ridges along the skirt of the closure. The configuration, arrangement, and spacing of the ridges and knurls about the closure provide an enhanced grip and feel, allowing for easier twist-off of the closure from a container. The closure may be used interchangeably with existing capping chucks used to apply conventional closures without requiring any modification to the capping chucks to apply the closures to containers during a capping process.

A container cap assembly includes an inner cap coupled to an inner surface and an upper end of a container neck and an outer cap maintaining the coupled state of the inner cap, thereby keeping the inside of a container sealed. The container cap assembly includes an inner cap including an outer wall portion corresponding to an inner surface of a neck of a container and a flange portion extending outward from an upper end of the outer wall portion to correspond to an upper end of the neck. An outer cap has a ceiling covering an upper portion of the inner cap and a side wall portion covering an outer circumferential surface of the neck, the ceiling and the side wall portion being integrally formed. The inner circumferential surface of the side wall portion has female threads corresponding to male threads on the outer circumferential surface of the neck.

The present invention relates to an assembly composed of a container for a fluid and a dispenser packaging which makes it possible to receive said container and envelop it, at least partially, said container comprising a dispenser and at least one flexible wall, the container being suitable for dispensing said fluid by means of the dispenser by deforming said at least one flexible wall, the dispenser packaging being suitable so that at least part of said at least one flexible wall is accessible from outside of said dispenser packaging when the container is placed inside said dispenser packaging.

A canister includes a closure configured to mount on a container to close an open mouth into a product storage region formed in the container. The closure includes a lid and a lid retainer coupled to the lid. The lid retainer is configured to mate with an external thread on the container to retain the closure in a mounted position on the container.
