An oxygen-shielding container lid according to the present invention comprises a high density polyethylene cap shell 1 having a skirt section 7 and a top plate section 5 provided with an inner ring 9 for intimate contact with an inner surface of a container mouth; and an in-shell molded body 3 provided in a portion of an inner surface of the top plate section which is surrounded with the inner ring 9. The in-shell molded body 3 is composed of a primary molded body 3a which has been formed by in-shell molding on the inner surface of the top plate section and which has an oxygen shielding function; and a secondary molded body 3b which has been formed on the primary molded body 3a by in-shell molding so as to cover the primary molded body 3a and to be fused and fixed to the inner surface of the top plate section at the peripheral edge of the primary molded body. A resin composition used for formation of the secondary molded body 3b contains linear low density polyethylene, and has a melt flow rate at 190? C. of 1 to 10 g/10 minutes, a density of 0.900 to 0.920 g/cm.sup.3, and a nominal tensile strain at break, as defined by JIS K-6922-2, of 400% or more.

A flow-limiting device that controls the distribution of unitary products from a container for holding said unitary products includes at least one dispensing opening, a body made of a polymeric material with an entry side, a dispensing side and a peripheral side extending in an axial direction of the body. The peripheral side has a lower and an upper axial end, the entry side has at least in part, a concave shape when viewed onto the entry side with at least one guiding surface. The dispensing side has at least in part, a concave shape when viewed onto the dispensing side. The dispensing opening is at an axial position between and spaced from the axial positions of the lower and upper axial end, wherein the entry side and/or the dispensing side include a plurality of elevated regions, which are arranged to define the concave shape.

A de-oxygenation stopper configured to enable aging of an oxygen sensitive material such as wine contained within a vessel, while minimizing oxygen content within the vessel. The stopper includes an oxygen scavenging element configured to remove and/or neutralize oxygen molecules within the vessel, and a sealing element formed of one or more materials having tailored oxygen transmission rate(s) configured to enable the material to age at a desired rate.

A tamper-evident closure containing an outer cap with a sidewall and a top wall having a tamper-evident member connected by a frangible structure; an inner cap with a sidewall and a top wall, coaxially nested in the outer cap; a protruding element between the top walls; a first engagement mechanism for driving the outer cap and the inner cap upon application of a rotational torque in a screwing direction; a second engagement mechanism for driving the outer cap and the inner cap upon application of a rotational torque in an unscrewing direction; and a third engagement mechanism for breaking the frangible structure upon rotational movement of the outer and inner caps.

Systems and methods for preserving oxidizable substances such as liquids or foodstuffs are disclosed. These systems incorporate a sealing device and an oxygen scavenging chemical or agent coupleable to the system. The oxygen scavenging agent can remove the oxygen from the headspace of a container such as a bottle of wine without reducing the pressure in the headspace to the extent that the flavor of the wine is adversely affected.

Storage containers and lids for such containers are provided. The lid has a first lid face and a second lid face. The second lid face has a rim configured to attach the lid to a storage bin. On the first lid face and extending to the second lid face is a plurality of apertures to provide airflow through the lid. A seal material extends from the second lid face that is configured to make the airflow path selectively sealable at a continuous wall and closed surface of a corresponding storage bin.

A device for the preservation of degradable substances (e.g. degradable by oxidation) such as liquids or powders, especially edible substances, beverages (e.g. wine), or foods (e.g. coffee) as well as oils, tobacco, pharmaceuticals, colorants or paints in an opened container, e.g. a bottle, exposed to the oxygen of the air is provided herein. Aspects of the invention include an apparatus for removing oxygen from an opened container or bottle by coupling the container or bottle to a shell that contains an oxygen absorbent material such as reduced iron.

A closure includes a polymeric top wall portion, a polymeric annular skirt portion, and a polymeric tamper-evident band. The polymeric 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, and first and second false threads. The internal thread formation includes a first closure lead and a second closure lead. Each of the first and second closure leads is in the form of a helix. Each of the false threads is located on roughly opposing sides of the closure. The first false thread assists in maintaining the contact between the first closure lead and a first finish lead of the container. The second false thread assists in maintaining the contact between the second closure lead and a second finish lead of the container. The polymeric tamper-evident band depends from and is at least partially detachably connected to the polymeric annular skirt portion by a frangible connection.

A system for sealing a beverage container includes a crown defining a bottom surface. A liner that includes an oxygen scavenger is coupled to the crown such that a top surface of the liner contacts the bottom surface of the crown. The bottom surface of the liner supports printed indicia where the bottom surface of the liner and the printed indicia are exposed to a beverage contained in the beverage container.

The present invention describes polymer compositions that have enhanced properties as oxygen barriers, as well as manufacturing methods for such oxygen-scavenging polymers and devices composed of such oxygen-scavenging polymers. These oxygen-scavenging polymers offer several benefits over existing materials, including a reduced ability for oxygen and carbon dioxide to permeate the polymer, reduced foaming of beverages stored in containers composed of the polymers, improved moisture absorption, and increased anti-bacterial/anti-fungal properties.
