A fluid transfer hub has a first vessel closure, a second vessel closure, a gasket arranged between the first vessel closure and the second vessel closure, and a clamp at least partially surrounding the first vessel closure, the second vessel closure, and the gasket. The first vessel closure has a first body, one or more apertures extending axially through the first body, one or more first inserts extending axially through the one or more apertures, and a cast seal disposed within the first body and surrounding each first insert. The second vessel closure has a second body, one or more apertures extending axially through the second body, one or more second inserts extending axially through the one or more apertures, and a cast seal disposed within the second body and surrounding each second insert.

Container assemblies are described herein that include a metal closure and a container including a plastic finish. The container assemblies may be characterized by improved performance including reproducibility of force needed to remove the closure. Furthermore, the container assemblies described herein may be compatible for use with hot-fill packaging processes.

A system and method for implementing cap closure for a carbonated beverage is disclosed. According to one embodiment, an apparatus includes a cap liner having a circular ring shape. The apparatus further comprises an outer lip and an inner portion of the circular ring shape. The outer lip is taller than the inner portion, and the outer lip has two or more structures extending away from a center of the outer lip.

In an aspect, a cap liner comprises a sintered fluoropolymer layer; and a backing layer; wherein the sintered fluoropolymer layer is in direct physical contact with the backing layer with no intervening layer located there between. In another aspect, a method of forming the cap liner of comprises plasma etching the sintered fluoropolymer layer to form a sintered plasma etched layer; and laminating the sintered plasma etched layer and the backing layer to form the cap liner.

The present invention relates to compositions (compounds) which can be used as seal material in vessel caps, even under pasteurization conditions and possibly sterilization conditions. More specifically, the invention relates to such compositions that are suitable for vessel caps that can be unscrewed, such as lug screw caps and in particular Press-on/Twist-off caps, and that result in a reduced migration of undesirable substances.

An insulating container may include an opening, which can be sealed by a closure. The closure may have 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 custom hair coloring container, components of the container, and method of use and doing business. In one embodiment, the container includes a container body, a hair colorant container section of the container body removably mountable to a peroxide container section of the container body, and the hair colorant container section and the peroxide container section collectively forming a cavity with an inside surface. The hair colorant container section may include a first interior seal threadedly engaged with the inside surface within the hair colorant container, and the peroxide container section may include second interior seal threadedly engaged with the inside surface within the peroxide container section.

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.

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.
