In the container, when the cap is capped on the container opening portion, an inner wall surface of a cylindrical sub-fitting wall portion of the cap and an outer wall surface of a large diameter opening portion of the container opening portion closely contact each other, and an outer wall surface of a cylindrical main fitting wall portion of the cap and an inner wall surface of a small diameter opening portion of the container opening portion closely contact each other. In this way, pressing force that is applied to the outer wall surface of the cylindrical main fitting wall portion of the cap from the inner wall surface of the small diameter opening portion of the container opening portion is increased.

A degradable containment includes an outer structural layer constructed of a pulp material, a central carrier layer constructed of a biopolymer, and an interior nanomaterial layer constructed of a nanomaterial.

An assembly of a closure with a container, for sealing of the container, comprises the container having an inner container surface defining a cavity opening to ambient through an opening, the closure comprising an upper portion and a lower portion, the lower portion having a lower lateral surface, the lower portion being adapted to be inserted into the opening of the container and two grooves provided on the lower lateral surface and adapted to receive two respective sealing members, the two grooves being separated by a predetermined distance, the two sealing members provided in the two respective grooves, the two sealing members being adapted to provide sealing between the lower lateral surface and the inner container surface, wherein the lower lateral surface, the inner container surface and the two auxiliary sealing members together define an annular space and a barrier sealant in the annular space.

A container system includes a first container including a bottom wall, at least one sidewall, and an open top, with a plurality of indented recesses formed in the bottom wall. A first lid closes the open top of the first container. A second container includes a bottom wall, at least one sidewall, and an open top. A second lid closes the open top of the second container, with a push indicator structure formed at a center portion of the second lid, and with a plurality of registration bumps formed about the push indicator structure. The first container is stackable on the second lid such that (i) each of the registration bumps in the second lid is aligned with an adjacent one of the recesses in the bottom wall of the first container and (ii) surfaces of the registration bumps are spaced from surfaces of the adjacent recesses.

A resilient fluid funneling assembly for use with a fluid dispensing vessel is described, and which includes a resilient main body defining, at least in part, a fluid collection region, and wherein a fluid draining aperture is formed in a predetermined location of the main body, and extends therethrough; and an elongated and resilient fluid draining conduit cooperates with the main body and which further is disposed in fluid receiving relation relative to the fluid draining aperture, and wherein the fluid draining conduit has a distal end which delivers a source of fluid which is collected by the fluid collection region to a user.

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.

Disclosed herein are embodiments of a plasma treatment system and methods for utilizing directed plasma to reduce instances of gas venting and leaking of contents from plastic bottles due to scratches occurring on sealing interfaces of the bottles and closures. In an embodiment, a plasma treatment system for repairing scratches applied to PET bottles comprises one or more plasma nozzles disposed along a bottle filling line and a plasma being issued by the plasma nozzles to repair the scratches. The plasma nozzles are arranged into a configuration that uniformly distributes plasma to all parts of a neck finish comprising the PET bottles. The plasma treatment of the PET bottles is performed prior to capping of the bottles. In an embodiment, the plasma treatment is performed after filling the bottles with contents so as to avoid a risk of scratches from misaligned filling tubes.
