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 child-resistant closure for a container with an outer screw thread opening, including an outer cap with a first sidewall and a first top wall and an inner cap with a second sidewall and a second top wall, the inner cap being coaxially nested within the outer cap and being provided with an inner thread to screw the inner cap onto the container. The outer cap and the inner cap include a first cooperating engagement means, and a second cooperating engagement means wherein the second cooperating engagement means includes a plurality of strip-like elastic members wherein each strip-like elastic member is inclined relative to the first top wall and includes a reinforcing element arranged between the first or second top wall and the strip-like elastic member connected thereto.

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.

Disclosed is a cap for a container and a container comprising such cap. This container typically accommodates loosely stored, solid products, such as strips, pills, tablets or the like. The cap includes a lid body with a top part and a peripheral wall, wherein the lid body includes a sealing skirt and an inner peripheral wall, which extend from the top part, and form a peripheral groove in between. At least one projection portion for partially covering the peripheral groove is integrally formed with the sealing skirt and the inner peripheral wall.

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.

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.

The invention discloses a food container for preserving freshness of food, comprising a container body having a cavity adapted for containing food items; a lid detachably secured on the container body to close the cavity of the container; and one or more food preserving elements capable of absorbing food spoiling gas to preserve freshness of the food items. The one or more food preserving elements are disposed inside the cavity and/or into a material of the food container to preserve the food items for an extended period of time and remove odors.

Many embodiments described herein prevent an aged spirit from degrading due to the oxygen trapped in the headspace without the use of a pump. The aged spirit preservation system may have a cork with an open top, an open bottom, and a channel extending from the open top to the open bottom. The cork may be sized couple to an internal portion of a bottle. The system may even include a sealing device coupled to an outer portion of the cork between the open top and the open bottom. Additionally, the system may include a replaceable cartridge containing an adsorbent media, iron, a salt, and a color-changing indicator. Oxygen from the bottle may be allowed to enter the cartridge and react with the iron via a non-reversible reaction, thereby preventing the degradation of the spirit.
