A fluid preservation device, for preserving a liquid within a container, which includes an elongated member with a proximal end and a distal end and an inner shaft and an outer shaft. The outer shaft and inner shaft are attached to an expandable sealing member. The expandable sealing member has an expanded state and a collapsed state and a state change mechanism attached to the proximal end of the elongated member to change the state of the expandable sealing member between the expanded state and the collapsed state. When the expandable sealing member is in the collapsed state, it can pass through an opening of a container and when the expandable sealing member is in the expanded state it is big enough to contact the inner surface of the container near the surface of the liquid.

A lockable, reusable plug for hermetically-sealing an opening, such as an alcoholic beverage bottle consists of a threaded wing bolt with an opening therethrough and a threaded stem; a domed, shouldered cap having an axial bore, an elastomeric sealing gasket having an opening, and a base nut having a threaded axial bore for mating with the threaded stem. Positioning the gasket between the compression cap and compression base nut, the bolt is inserted through the assembly, making the plug ready for insertion into an opening to be sealed. A flange on the gasket and the cap support the plug on the rim of the opening to be sealed. Screwing the bolt further into the assembly urges the plates toward one another compressing and causing the gasket to extend radially outward creating the seal. Insert the shackle of padlock through opening of bolt, lock padlock, shoulders prevent removal of plug.

A sealing cap includes an outer cap, an inner cap and an air-tight gasket. The outer cap is to be disposed on a container. The inner cap is movably connected beneath the outer cap. The air-tight gasket is sleeved around the inner and outer caps. Two connectors extend through the outer cap and are connected to the inner cap. An operator is disposed above the outer cap and is pivotally connected to the connectors. The operator is operable to move the inner cap relative to the outer cap between a pressurizing position, where the inner cap pressurizes the air-tight gasket against the container, and an unpressurizing position, where the inner cap unpressurizes the air-tight gasket against the container.

Container for e.g. wine has a vessel, a seal assembly, and a handle assembly. The seal assembly has upper and lower seal compressor moldings on major faces of a seal, and seal's edge expands in response to moving the seal's major faces together to increase a diameter of the seal. Pressure on a glass vessel is sufficiently low to prevent the glass from cracking or breaking, and pressure can be sufficiently high to prevent air from entering the enclosed volume. Methods and parts associated with the container are also discussed.

An automated stopper and opener includes: a sleeve housing that is able to fit within a neck of a container; a mechanical feature that is able to vary a force applied to an internal surface of the sleeve such that a seal is able to be formed or released within the neck of the container; and an electronic controller that is able to manipulate the force applied to the internal surface of the sleeve by at least partly directing operations of the mechanical feature. An automated stopper includes: a cylindrical sleeve; a mechanical element that fits within the cylindrical sleeve and has a variable outer diameter; a communication interface that is able to receive commands from a user device; and a controller that is able to interpret the received commands and direct the mechanical element to control the variable outer diameter. A system includes automated stoppers and a user device.

The present invention relates to a stopper for a bottle designed for commercial bottling of a beverage or liquid food, preferably a wine bottle, and a sealing element for sealing the stopper in the mouth of the bottle, which is separate from the bottle. The stopper comprises a stopper part for introduction into a mouth of the bottle, and a head part for remaining outside the mouth of the bottle, the head part having a diameter that is larger than that of the stopper part, wherein the stopper part comprises a an interlocking mechanism for engaging with a counterpart interlocking mechanism of the sealing element. The sealing element is configured to be forced against an inner wall of the mouth, thereby being brought into a sealed position, upon introducing the stopper part into the mouth, in which sealed position the stopper is held on the bottle. The interlocking mechanisms are configured to permit bringing the sealing element into an unsealed position by an unsealing action which comprises rotating the stopper with respect to the bottle.
