The compartment upper cover is arranged with a plastic upper cover layer, an outer surface of the cylinder body is wrapped with a plastic lower cover layer, and the plastic upper cover layer is combined with the plastic lower cover layer to fasten and wrap the compartment upper cover and the cylinder body.

A heated slurry transport system for receiving, transporting and unloading a cuttings slurry in a non-frozen manner in cold weather environments. The heated slurry transport system generally includes a portable tank having an interior surface, at least one wall, and a rear door. A layer of insulation surrounds at least a portion of the portable tank to help retain heat within the portable tank. A heating unit is attached to the portable tank and adapted to heat a fluid that is transferred through at least one heat loop attached to the portable tank to heat the interior of the portable tank and the contents of the portable tank.

The present disclosure relates to a vacuum preservation device, comprising a drawer including a drawer panel at the front end of the drawer, and a handle assembly. The handle assembly is coupled to the drawer panel, wherein the handle assembly includes a door body sealing assembly and a handle. A preservation container body comprises a preservation container body fixing part and a preservation container body sliding part. An electric push rod is coupled to the preservation container body and is coupled to the preservation container body sliding part and to the preservation container body fixing part.

The present disclosure provides secure storage containers, e.g., which may be used as a vessel to store and/or transport medication, controlled substances, and other materials.

To provide a medical device container, which enables transportation of a stored medical device in a fixed condition. A medical device container includes a container body having an opening portion at the upper portion; a holder, which is housed in the container body, for holding at least one medical device; and a gas non-permeable film sealing the opening portion of the medical device container; wherein the internal pressure of the medical device container is set to a value less than the atmospheric air pressure.

A support includes a central portion configured to receive one or more products, a perimeter band which completely surrounds the central portion, a projection defined at the perimeter band and exhibiting at least one raised portion emerging with respect to the perimeter band and extended away from said central portion. The raised portion a through channel crossing the projection and having an access opening which is completely extended at a position spaced from the perimeter band and is configured to enable gas to pass into the through channel through the projection. The central portion and the perimeter band are made of sheet material.

A pump mechanism for vacuum sealing an airtight cavity formed by a container and a lid, including a bore having a first one-way seal allowing air from the airtight cavity to enter the bore and blocking air inside the bore from returning to the airtight cavity and a second one-way seal allowing air inside the bore to leave the bore without returning to the airtight cavity and blocking air outside of the bore from entering the bore, a piston disposed inside the bore, and a chamber of air enclosed by the bore, the first and second one-way seals, and the piston, wherein actuation of the piston in a first direction causes air to evacuate the airtight cavity and enter the chamber through the first one-way seal, and wherein actuation of the piston in a second direction causes air to exit the chamber through the second one-way seal.

The invention relates to a dishware unit for packaging, transporting, and/or serving meals and to a method for sealing at least partially prepared meals, comprising a body which is covered with a film. An adhesive is introduced between the film and the body in an adhesive region in order to seal the dishware unit. The film and the dishware unit have such a degree of surface tension that the adhesive at least largely adheres to the film when the film is removed, wherein the surface tension in the adhesive region in the film is greater than the surface tension in the adhesive region in the body.

A double-layer keg comprises an outer barrel and an inner barrel made of plastic disposed in the outer barrel. A bottom of the outer barrel is fixed with a base, and a lower portion of the outer barrel has a brace for supporting a bottom periphery of the inner barrel. A spear structure is installed at a barrel opening of the inner barrel, and an upper portion of the inner barrel has a shoulder and a neck disposed around the barrel opening. An inner surface of an upper portion of the outer barrel is pressed against an outer surface of the shoulder and/or the neck of the inner barrel. An expansion space, provided for the bottom of the inner barrel to expand downward, is disposed between a portion of the bottom of the inner barrel located at an inner side of the brace and the base.
