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.

Container for e.g. wine has vessel, seal assembly, and handle assembly. 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 auxetic structure consistent with the present disclosure may include a core cell, capable of rotation, including a plurality of first rib sections, and a plurality of second rib sections. The first rib sections may be transverse to a longitudinal axis of the auxetic structure and at least one of the first rib sections may extend from the core cell. The second rib sections may be transverse to a transverse axis of the auxetic structure and at least one of the second rib sections may extend from the core cell.

A food container and its method of construction are disclosed herein. In an embodiment, the food container includes a body and a lid assembly. The body has an interior space. The lid assembly lid assembly includes at least one slide part and a rotating part. The at least one slide part is configured to translate linearly when the rotating part is rotated by a user to cause the interior space to be sealed or unsealed.

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 packaging product and a method of closing a packaging product are provided. Closing a packaging product may include providing a first member of the packaging product having an aperture therein and providing a bubble rivet extending through the aperture and having an expanded hollow head portion on one side of the aperture with a neck portion of the bubble rivet being provided in the aperture. The hollow head portion of the bubble rivet is breakable to enable withdrawal of the head portion through the aperture thereby non-reversibly opening the packaging product.
