Bottle stoppers/corks we disclosed that cam easily be removed from bottles. These bottle stoppers do not requite the use of an external tool in order to remove the stopper. The stoppers are designed in such a way that the stopper deforms in a way that the stopper can be easily removed from and/or inserted into a bottle/container without great effort. The stopper is designed so that it has both a cork portion that is inserted into a bottle and a removal portion that resides largely outside the bottle. The removal portion comprises a loop that allows an individual to pull on the loop in a direction along the length of the cork portion, thereby facilitating removal of the stopper from the bottle.

A beverage-packaging container is provided that includes a container body for receiving the liquid and a cork stopper for sealing the liquid contents within the container body. The sidewalls and bottom wall of the container body are formed of paperboard and are preferably formed of a layered, recycled paperboard. The top wall of the container body is formed of a cork material with a cork-receiving hole disposed within the top wall. The cork stopper has a truncated cone-shaped portion that is configured to engage frictionally with the edges of the cork-receiving hole. The cork stopper may also have a wooden crown to aid the user in grasping and removing the cork stopper from the top hole of the container body.

A bottle includes a neck and an opening at an end of said neck. A closure member closing the opening is provided with locking means that secure the closure member to a rim of the opening. The locking means include a collar surrounding a neck portion of the neck and locking-levers that are hingedly connected to the collar. The closure member includes outwardly extending lugs that register with the locking-levers. The locking-levers include link members that releasable engage the lugs at a top surface thereof. The locking-levers are retractable to a closed position in which the link members clamp the closure member to the rim of the opening.

A closure for a container is disclosed. The closure comprises 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 styrene block co-polymer, wherein the core member has a density in the range of from about 100 kg/m.sup.3 to 350 kg/m.sup.3 and the peripheral layer has a density in the range of from greater than 350 kg/m.sup.3 to about 1,500 kg/m.sup.3 and a thickness in the range of from 0.15 mm to less than 0.50 mm.

A rigid stopper (10) made of bisphenol-free polycarbonate and silicone synthetic materials, particularly for a wine bottle (48), comprises a cylindrical body (12) and two opposing faces (16, 18), and at least two compressible-elastomeric “O”-rings (22, 24) seated in corresponding circumferential grooves (26, 28) on a side (14) of the body (12). The faces (16, 18) are comprised of foramen (42, 44) respectively which communicate with a volute-cavity (40) for the purpose of accepting a cork-screw-extractor. The volute-cavity (40) is comprised of a partition (46) at a central-plane (56) for the purpose of preventing wine from leaking through the volute-cavity (40). “O”-rings (22, 24) are compressively forced into a mouth (50) of a bottle (48) positioning either face (16) or face (18) flush with the mouth (50) thereby providing adequate compressive force in maintaining position of the stopper (10). Stopper (10) having longitudinal symmetry about a central plane (56), either face (16) or (18) of stopper body (12) maintains compatibility with random orientation of the stopper (10) in “corking” process of packaging.

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.

The invention relates to a biodegradable stopper comprising a casing of rigid biodegradable material, consisting of an annular body with a covered flank, and an internal ring of biodegradable elastic material the total width of which is equal to or smaller than the internal width of the annular body, comprising one or more internal recesses in which one or more portions of the ring fit.

Stopper intended for bottling still wines, characterized in that it includes

cork strips laterally joined by a polyurethane binder so as to form a plurality of cork strips, the cork strips being disposed such that the thickness thereof is perpendicular to the axis of the stopper,
at least one lateral cork strip joined by a polyurethane binder to each face of the plurality of cork strips revealing all cork strips,
the lenticels possibly present in the cork strips extending parallel to the thickness of the strips while those in the lateral cork strips extend perpendicular to the thickness of the strips, such that all lenticels of the stopper are disposed perpendicular to the axis of the stopper in order to limit the variation in oxygen permeability from one stopper to the other

The present invention relates to devices for corking bottles, and more particularly to the corking of glass bottles having necks containing a cork with an upper portion which rises above a rim, and may be used for corking bottles. A device for corking bottles contains a neck with a rim, and a cork, an end portion of the rim having protrusions, providing the ability to raise the cork by rotating same by the upper portion thereof. The neck, rim and upper portion of the cork are rectangular and/or oval in horizontal cross-section. The neck and rim are, on the two wide sides thereof, made in the form of parallel flat common surfaces. The narrow sides of the rim are hook-shaped.

The present application discloses a cork coding method and device, a cork tracing method and device, and an electronic device, wherein, the cork coding method comprises: acquiring an original image of a to-be-coded cork with an original character code; identifying the original character code in the original image; determining whether the original character code is matched with a character already inputted into a database; extracting an original texture feature of an to-be-coded cork from the original image, if the original character code is not matched with the character in the database; and establishing a one-to-one correspondence between the original texture feature and the original character code. In the method the original character code on the cork corresponds to the original texture feature on the cork, to guarantee the uniqueness of the original character code and the original texture feature
