A closure for a product-retaining container is constructed for being inserted and securely retained in a portal-forming neck of said container. The closure comprises: a plastic material comprising at least one thermoplastic polymer; a plurality of particles comprising cork; and at least one processing aid. Optionally, one or more additives and/or blowing agents may be included. A method for manufacturing a closure comprises intimately combining multiple components, heating the resulting composition to form a melt, forming a closure precursor from the melt, and optionally cutting and/or finishing the closure precursor to form the closure.

Closure for a product-retaining container

A method for manufacturing a closure constructed for being inserted and securely retained in a portal-forming neck of a product-retaining container is provided. Such method may include intimately combining a plurality of particles comprising cork and having a specified particle size distribution with a plastic material including one or more thermoplastic polymers, optionally in combination with other constituent(s) to form a composition, heating the composition to form a melt, extruding or molding a closure precursor from the melt to provide a specified water content range, and optionally cutting and/or finishing the closure precursor. A composition for use in manufacturing a closure for a product-retaining container includes a plurality of particles comprising cork and having a specified particle size distribution with a plastic material including one or more thermoplastic polymer, optionally in combination with other constituent(s). Methods for producing particulate material, cork composite material, additional methods for producing closures, and resulting closures are also provided.

Method for manufacturing a closure for a product-retaining container

A method for manufacturing a closure constructed to be inserted and securely retained in a neck of a product-retaining container includes intimately combining a plurality of coated particles (each comprising a cork material core and a first plastic material) with a second plastic material, and other optional constituents; heating the composition to form a melt; extruding or molding a closure precursor from the melt; and optionally cutting and/or finishing the closure precursor. A composition for use in manufacturing a closure includes a plurality of coated particles (each comprising a cork material core and a first plastic material) with a second plastic material, and one or more blowing agents. Methods for producing particulate material, cork composite material, and additional method for producing closures are also provided.

A closure constructed for being inserted and securely retained in a portal-forming neck of a container, the closure having a substantially cylindrical shape and comprising substantially flat terminating surfaces forming the opposed ends of the closure, wherein the closure further comprises: (a) a closure precursor having a substantially cylindrical shape and comprising a lateral surface and substantially flat terminating surfaces forming the opposed ends of the closure precursor, wherein the lateral surface and the flat terminating surfaces of the closure precursor have a substantially uniform color; and (b) a decorative layer that at least partially covers at least the lateral surface of the closure precursor.

Decorative closure for a container

A method for manufacturing a closure constructed for being inserted and securely retained in a portal-forming neck of a product-retaining container is provided. Such method may include intimately combining a plurality of particles comprising cork and having a specified particle size distribution with a plastic material including one or more thermoplastic polymers, optionally in combination with other constituent(s) to form a composition, heating the composition to form a melt, extruding or molding a closure precursor from the melt to provide a specified water content range, and optionally cutting and/or finishing the closure precursor. A composition for use in manufacturing a closure for a product-retaining container includes a plurality of particles comprising cork and having a specified particle size distribution with a plastic material including one or more thermoplastic polymer, optionally in combination with other constituent(s). Methods for producing particulate material, cork composite material, and additional methods for producing closures are also provided.

By securely affixing or bonding a multi-layer film to the terminating end of a closure/stopper, with the multi-layer film being constructed for promoting the transfer of all of the desirable gases, chemicals, and/or compounds while preventing the transfer of undesirable gases, chemicals, and/or compounds, a unique, closure or stopper having a sealed and/or barrier bearing terminating end is achieved. In this way, wine sealed in the wine bottle by the closure/stopper of the present invention is assured of possessing a long storage life, while also having the flavor, bouquet, taste, and quality desired for the wine fully maintained.

The disclosure relates to a synthetic closure for a product-retaining container constructed for being inserted and securely retained in a portal-forming neck of said container, said closure comprising at least a core member comprising at least one thermoplastic polymer, and at least one peripheral layer at least partially surrounding and intimately bonded to at least one surface of the core member, said peripheral layer comprising at least one thermoplastic polymer, wherein the synthetic closure is formed by extrusion, and at least one of the core member and the peripheral layer comprises a plurality of cells, and wherein the synthetic closure comprises cork powder.

Container closures wherein at least one void comprised in the closure is at least partially filled with a gas or gaseous mixture which by composition or pressure is different from air are disclosed. The oxygen content of said gas can be lower than the oxygen content of air. Through use of such closures for sealing closed containers, the amount of air and therefore oxygen that enters the closed container through closure desorption can be effectively controlled, changed, or even largely eliminated.

Closures for a product retaining container and related systems and methods

The disclosure relates to a cylindrical closure for a product-retaining container constructed for being inserted and securely retained in a portal-forming neck of said container, said closure comprising at least one thermoplastic polymer and at least one natural organic filler wherein the lateral surface of said closure has a hardness of 40 to 90 Shore A. Such closures are particularly suitable for sealingly closing wine bottles.

A synthetic closure for a product-retaining container is constructed for being inserted and securely retained in a portal-forming neck of said container, said closure comprising at least a core member comprising at least one cycloolefin-based copolymer.

By providing a synthetic closure which comprises at least one thermoplastic polymer and, as an additive, at least one fatty acid derivative, in particular a fatty acid ester or a fatty acid amide such as a stearamide, a synthetic closure is attained which achieved substantially enhanced properties. In particular, it has been found that the oxygen transfer rate of the closure is reduced substantially, thus reducing unwanted oxidation of wine. Furthermore, the use of a fatty acid derivative additive improves the performance characteristics of synthetic corks, such as extraction force, ovality control, diameter control and length control.

Synthetic closure

A closure for a container, such as, for example, a wine bottle, is provided. In one embodiment, the closure includes an oxidant releasing agent that is adapted to release oxygen into an interior portion of the container according to a predefined desired profile. In another embodiment, the closure comprises a gas containing reservoir, a membrane and a barrier layer, the membrane allowing an at least partial exchange of gas between the inside of the reservoir and the inside of the container, and the barrier layer at least partially preventing exchange of gas between the outside of the closure and the inside of the reservoir.
