A vacuum bag assembly includes a bag that may contain yard waste. A valve is coupled to the bag such that the valve is in fluid communication with an interior of the bag. The valve is selectively coupled to a vacuum thereby facilitating air to be drawn out of the bag such that the bag is collapsed to a minimum size. A closure is coupled to the bag and the closure is selectively manipulated. The closure selectively closes the bag to retain the yard waste in the bag. Moreover, the closure forms a fluid impermeable seal to inhibit air from entering and escaping the bag.

A cap for a cup includes a piston seat which includes a room, and an aperture is defined through the lower end of the piston seat. An air path communicates with the aperture. A check valve is movably engaged with the lower end of the piston seat and includes a plate which is deformable to control the air path to be opened or closed. A suction device is located in the piston seat and includes a position rod whose lower end is connected to a piston head which is located in the room of the piston seat. The upper end of the piston rod protrudes beyond the top end of the piston seat and is connected to a handle. By pulling and pushing the handle, the air in the cup is sucked out.

A cap apparatus includes a cap body and a valve body. The valve body includes an upper portion, a lower portion, and a stem intermediately disposed between the upper portion and the lower portion, the valve body including a bore formed therein having concentric alignment to and traversing the upper portion and the stem, and the valve body including a perforation formed therein having concentric alignment to and traversing the stem and the lower portion. The perforation forms a substantially impermeable seal within the valve body. The cap body includes an aperture in coaxial alignment with the bore and the perforation. The inner surface of the cap body includes multiple internal threads.

A method and apparatus for reliably vacuum packing any size bottle, jars or bowl. The method being to stack progressively larger overlapping vacuum lids atop one another to fit size opening of a food storage container. The apparatus consisting of an assembly of overlapping circular vacuum lids wherein the bottom surface of each circular vacuum lid is covered with a flexible elastomeric gasket that can form an air-tight seal with either a mating overlapping circular vacuum lid or the opening of a food storage container.

The present disclosure provides a carbonation preservation device that attaches to the mouth of an open container holding carbonated liquid. More specifically, the present invention relates to a device for preventing loss of carbonation from a carbonated liquid stored within a container by purging the trapped air above the remaining liquid within the container and replacing it with carbon dioxide or mixture of gases. When in place, the carbonation preservation device purges the air and other gases from the volume above the remaining carbonated liquid and fills the volume with a gas, such as carbon dioxide, or a mixture of gases, in order to pressurize the container and prevent the escape of carbon dioxide from the remaining carbonated liquid in the container.

Containers such as boxes or tubes may be lined with deflated air bladders or reservoirs. When an item is placed in such a container, the container may be sealed, and the air bladders or reservoirs may be charged with air until such bladders or reservoirs surround and fully cushion the item within the container. The bladders or reservoirs may be formed from lightweight and flexible materials, such as polyethylenes, polyphenylenes or other plastics, and charged with air manually or automatically from an external source via a valve or other component extending through the containers. An internal pressure within one or more of the bladders or reservoirs may be monitored during the charging, and the charging may be secured when the internal pressure meets or exceeds a predetermined threshold.

A system for preserving a surgically explanted tissue sample has a first packing station for placing the tissue sample in a selected container among a plurality of containers of different sizes. Each container has a hermetic lid (50) with an opening (33) equipped with a non-return valve (51). The system also has a final packing station equipped with a filling system for filling the selected container with a preservative substance, including a nozzle-holding head (28) mounted movable on a vertical guide (29). A method is also described which provides for the selection of the container based on the evaluation of the volume of the tissue sample, the hermetic closure of the container immediately after the insertion of the tissue sample. and the filling of the container by means of a nozzle (31) of a filling system inserted in the non-return valve (51) of the hermetic lid (50).
