An apparatus for preserving carbonated beverages or other liquids features a container, and an impermeable piston that divides the container interior into a lower chamber beneath the piston for storage of a liquid, and an upper chamber above the piston. An axially extendable and collapsible conduit has a lower end sealed to the piston around a flow opening that passes axially therethrough, and an upper end connected and sealed to an upper portion of the container around a mouth opening therein. A valve mechanism features a closure member movable between open and closed positions that respectively open and close the flow opening in the piston. Opening of the closure member allows pouring of the liquid out of the container via the flow opening, the conduit and the mouth, and closing of the closure member seals the lower chamber closed in order to preserve the liquid.

Disclosed is a multi-compartment container including features that permit the rupture or opening of a seal between compartments to enable mixing of the materials within each compartment, as well as a vapor permeable region to permit vapor to escape after mixing.

Implants are described herein which contain an activated adhesive on at least a portion of the surface of the implant. A release sheet may be positioned over at least a portion of the adhesive. Packages which contain the implants and methods of preparing the implants are also described.

Methods and apparatus for liquid preservation according to various aspects of the present invention may comprise a vessel and a displacer. The displacer may be disposed in an interior volume defined by an interior surface of the vessel. The displacer may change the volume of the interior volume. An aperture at an apex of the displacer or vessel may allow air to escape from the interior volume as the displacer decreases the volume of the interior volume. An at least partially transparent displacement indicator may be positioned atop the aperture.

Beverage containers are provided for storing liquid contents. In various embodiments, containers are provided with devices and means for allowing a controlled ingress or oxygen or similar material to the container contents. In preferred embodiments, devices and methods for storing wine are provided.

The present invention relates to a container for keeping fermented food, having for example, a main body for accommodating fermented food in an interior space; a pressing plate coming into contact with the surface of the fermented food in the main body; and a cover for blocking the opening of inside of the main body; wherein the main body has a stepped part protruded inwards from the inner circumferential surface of a neck part at an upper end portion, and the pressing plate has a protruded rim provided to the periphery of the upper end portion thereof so as to be placed on the stepped part, a vertical section provided to the lower end of the protruded rim and having an outer circumferential surface coming into contact with the inner circumferential surface of the stepped part, and a round surface provided at the lower end of the vertical section and having a bottom surface part coming into contact with the surface of the fermented food.

Methods and apparatus for liquid preservation according to various aspects of the present invention may comprise a vessel and a displacer. The displacer may be disposed through an open top of the vessel into a cylindrical interior volume defined by an interior surface of the vessel. An outer rim of the displacer may form a movable seal with the interior surface of the vessel so that the displacer may move within the vessel parallel to the interior surface and below the open top. The displacer may include an aperture at an apex of the conical displacer, which allows air to escape from the interior volume as the displacer decreases the volume of the interior volume. An at least partially transparent displacement indicator may be positioned atop the aperture.

Disclosed is a device for protecting and preserving a substance in a container. The device may include a plurality of overlapping sectors capable of rotating about a pivot point such that the device has a substantially disc shape when fully expanded and a substantially pie shape when partially expanded; and a lip defining an outer diameter of the device when fully expanded. The outer diameter of the device is equal to or greater than an inner diameter of the inner surface of the container.

Methods of covering an animal feed product involve depositing in an open end of a container an animal feed. Placing a cover on an exposed surface of the feed at the open end of the container, where the cover includes a flowable coating arranged on one side of a flexible film and a rigid or semi-rigid layer bound to an opposite side of the film. The exposed surface of the feed comprises irregular surface structures due to feed components positioned at the exposed surface. A central portion of the flexible film of the placed cover conforms to the irregular surface structures at the exposed surface of the feed upon the flowable coating reaching a temperature of at least about 125 F.

A perishable particle compression container stores and preserves a quantity of perishable particles, such as dry good particulates, coffee, tea, or tobacco. The compression container includes a container body and a lid. The container body includes a container-compression blade connected to a lateral wall, a container base, and a container-blade support. The lid includes a lid-compression blade connected to a lid base, and a lid-blade support. The lid-compression blade is positioned within the container body as the lid engages the container body. The lid pivots about the container body to allow the lid-compression blade to rotate around the container-blade support and compress the perishable particles within the container body.
