Aspects and techniques of the present disclosure relate to an internal cover/vent handle arrangement, in association with a container, such as a 5 gallon bucket with a slanted sidewall for evacuating air volume above stored material. The disclosure relates to a squeeze-actuated vent valve arrangement arranged and configured to be easily operated even while deeply recessed in the bucket. The disclosure also relates to a deflectable outer seal arrangement configured to seal against a slanted sidewall of a bucket.

A preservation device allows for the safe storage of wine and other liquids subject to change over time. When wine is stored in a partially filled container, the wine degrades due to the presence of oxygen. The preservation device has an integral inelastic low mass barrier bag that fits within the wine bottle, in an unexpanded or collapsed form. The barrier can be expanded into the headspace of the container by introducing air into the bag from a pump, excluding ambient gasses and reducing the amount of air in contact with the stored fluid. Because of its low mass, the inelastic barrier bag remains substantially expanded in the container due to the surface attraction with the container walls as well as the rigidity imparted to the barrier bag by its material characteristics. No stopper is required to maintain the barrier in an expanded state.

A package for storing perishable goods. Film forming the package has an inner layer that defines an interior surface of the package and is formed from a polyethylene and a tack agent that has migrated to the interior surface to provide tackiness. The tackiness permits cold resealing of the package after it has been opened, without substantially adhering to the perishable goods so that the perishable goods can be non-destructively removed from the package. An outer layer of the film defines an exterior surface of the package and is formed from another polyethylene. The polyethylene of the outer layer is configured to block migration of the tack agent through the outer layer such that the exterior surface is substantially non-tacky.

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 reusable apparatus for storing and delivering a sterile product. The apparatus includes a compressible reservoir adapted to allow for filling, storing, and delivering the sterile product, and a sterile inlet and outlet device including an inlet portion and an outlet portion. The sterile inlet and outlet device is connected to the compressible reservoir and adapted to allow the sterile product to be filled from exterior to the reusable apparatus and into the compressible reservoir through the inlet portion and adapted to allow the sterile product to be delivered from the compressible reservoir through the outlet portion.

A fluid insulation assembly for use with a container that is configured to contain a fluid includes a barrier assembly configured to fluidly isolate a first fluid chamber within an interior of a container, wherein the first fluid chamber is configured to contain a fluid, and an actuation assembly configured to dispense fluid contained within the first fluid chamber.

A method for insulating a fluid within a container and dispensing the fluid from the container includes fluidly isolating a first fluid chamber within an interior of a container and moving a barrier assembly disposed within the interior of the container in a first direction for dispensing fluid contained within the first fluid chamber.

A method of controlling gas composition within a container containing respiring produce is described. The container includes at least one gas outlet and at lease one gas inlet and the method includes the steps of: drawing a selected gas from within the container through a selective membrane element and through the at least one gas outlet; detecting ambient pressure inside the container; and introducing ambient air under selected control conditions from outside the container into the container through the at least one gas inlet in response to the detected ambient pressure to control the relative composition of gases inside the container.

A system and method for protecting biological or other material from contamination through the steps of filling, freeze-drying, packaging, storing and use are disclosed. A system can include a flexible container, a membrane configured to transmit air or solvent vapor out of the flexible container, and a membrane frame supporting the membrane and engaged with at least one column member. The at least one column member can be configured to maintain the membrane and the membrane frame a spaced distance from one or more contents received within the flexible container. Upon application of a downward force, the at least one column member can assume a collapsed configuration. A method can include inserting a biological material, for example, into a flexible container, freeze-drying the biological material, moving the freeze-dried biological material to a portion of the flexible container that includes at least one port, and sealing the biological material within the portion.
