The present disclosure describes bottle closure assemblies which are made at least in part with a polyethylene composition having good flow properties and good resistance to environmentally induced stress cracking. The bottle closure assembly includes a cap portion, an elongated tether portion, and a retaining means portion. The retaining means portions engages a bottle neck or an upper portion of a bottle. The elongated tether portion connects at least one point on the cap portion to at least one point on the retaining means portion so as to prevent loss of the cap portion from a bottle.

An insert having a compartment that can be secured into a cap of a container is disclosed. The compartment can be used to store a humectant, desicant, or other material, which can be used to help preserve the contents of the container, such a food product or a pharmaceutical. The insert has a main body, a sidewall that surrounds the main body and extends upwards to define the compartment. A flange extends outwardly from the top of the sidewall that engages with the inner surface of the cap. The insert can be comprised of a resilient material to allow it to deform to fit within the cap and to secure it within the 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.

A cap for a fluid container includes a cap body including a base surface at a first end and an opening at a second end. The cap body is engageable with the fluid container. The base surface includes a first engagement structure. The cap includes a first aperture in the base surface. The cap further includes a key code body including a second engagement structure engageable with the first engagement structure. The key code body includes a key code ring. A removable closure member includes a plurality of engagement surfaces and a sealing surface disposed opposite the plurality of engagement surfaces. The removable closure member includes a sealing mechanism including a sealing member on the sealing surface. The sealing member is engageable with a portion of the base surface that defines the first aperture.

A retortable container is formed with an opening formed defined by a projecting rim. The rim includes an external surface and securing structure formed thereon. A flexible membrane is sealed to the rim and closes the opening. A closure is provided having a molded plastic tubular ring and a separately formed molded plastic disk. The tubular ring includes an overlapping flange at a top and directed inwardly towards an inwardly positioned open area. The skirt includes an engagement structure for securing the closure to the external surface of the rim. The disk is separately attached to the ring within the open area after the retort process is applied to the sealed bottle.

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

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 dual-threaded adapter comprises a cylindrically-shaped body. The body includes an externally-threaded male connector and an internally-threaded female receptor, the male connector and female receptor mutually joined forming the body. The body also includes a channel formed internally within the body by the male connector and the female connector, the channel providing fluid communication therethrough.

A composite closure assembly includes a closure shell having a closure socket surrounded by a shell wall and a shell end. An inner closure is within the closure socket. The inner closure is fixed to the closure shell. The inner closure includes a closure wall and a closure end. A closure gap is between the shell end and the closure end. A support brace including one or more support braces extends from the closure end to the shell end and bridges the closure gap.

The present invention relates to a child resistant closure for a bottle or container. More specifically, the present invention relates to improved two-cap structure assemblies.
