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.

An air contact reducer for food storage is described herein. The air contact reducer may be a single piece of plastic. The air contact reducer may be round or rectangular to match the shape of a food container. The air contact reducer may include a knob or handle to help move the air contact reducer up or down (or back and forth in some cases) to reduce the air contact with food while the food is being stored.

A guacamole keeper includes a container having an open top and a flared rim, with upwardly extending sidewalls to form an interior space for holding guacamole or other food items of a similar consistency. A removable lid is configured with a peripheral flange. The lid is sized and arranged to fit inside the vertical sidewalls of the container, with a flange engaging the interior sidewalls to form a seal. The lid can be pressed entirely or substantially to the base of the container, with the flange engaging the sidewalls throughout most or all of the travel between the top and the bottom of the container

A disassembleable, reusable plastic container that can be used for the manufacture, storage and transportation of cheese products. The container may utilize wrap-around interlocks. The endwalls of the container may be flexible to allow the container to undergo minimal deformation when filled with cheese products. The container may also have a recessed pressboard that allows for increased capacity in the container. The container may also utilize positive corner interlocks that minimize unintentional disengagement.

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 decanter arranged to permit storage of wine or other beverage while isolated from ambient air and employing a variable size beverage storage volume. A valve may control flow past a piston as the piston is moved relative to a container to adjust a size of the beverage storage volume.

The present invention relates to a refill container using double injection, comprising: a refill container for containing a cosmetic material, wherein the refill container is formed of a synthetic resin or a metallic material and has an impregnation member in which the cosmetic material is impregnated; a refill container holder which is coupled to the top of the refill container; and a refill container cover which is opened and closed by being hinge-coupled to the refill container holder, wherein the refill container holder is formed by doubly injecting or insert-injecting a packing part of an elastic material therein, and the top of the refill container and the packing part are coupled when the refill container and the refill container holder are coupled.

An apparatus and method for separation of air from fluids, whereby a contractable partition, a throat seal, and air vents are provided, which allow an inside portion behind the contractable partition to expand into or contract from an outside portion, increasing or decreasing the side of the inside portion to accommodate changing volumes of beverage, thereby preventing the entry of contaminating air and slowing the loss of carbonation of the remaining beverage.

A rust-proof storage container includes a container body defining a storage space and a barrier material provided so as to seal a passage or an opening of the container body and having an area greater than a cross-sectional area of the passage or an area of the opening, the barrier material being sheet-like and having flexibility. A peripheral portion of the barrier material is fixed all around a periphery of the passage or a periphery of the opening and airtightness of the storage space is maintained by the barrier material. A center portion of the barrier material includes a first surface being a surface facing the storage space and receiving a first atmospheric pressure of the storage space and a second surface being a surface opposite the first surface and receiving a second atmospheric pressure of an outer space.

A liquid-containing combination container includes a first container that contains a liquid, a second container that contains the first container and that has an oxygen barrier property, and an oxygen absorber that absorbs oxygen in the second container. The first container includes a container body that includes an opening portion and a stopper that closes the opening portion, the stopper has oxygen permeability.
