This invention provides methods for coating food and beverage containers using polymers which are preferably polyether polymers. The invention further provides liquid and powder coating compositions including such polymers and which have utility in a variety of other coating end uses, including, for example, valve and pipe coatings.

The present invention includes a kit that includes a container with a removable lid that is operable to create a seal around the container, and an internal release mechanism that is operable to sever the bond between the food and the surrounding container so that food items can be easily removed from the container. The release mechanism comprises a bottom member and two opposing side members extending therefrom that are configured to conform to the contours of the container and is operable to dislodge food from the interior surface of the container in a sweeping fashion by rotating the release mechanism within the container. The release mechanism may be fastened to the bottom of the container and optionally may include a lip to aid in scraping food from the container.

An airtight device includes a container and an airtight cover on the container, and the airtight cover includes a fixing bracket, a door, and a pressuring handle. The fixing bracket has a through hole and a guiding slot, and the through hole communicates with internal space of the container. The guiding slot has adjacent first and second top surfaces, and the second top surface is higher than the first top surface. The door selectively covers the through hole. The pressuring handle pivoted on the door has a first section, a second section, and a rotating axis between the first and second sections, and the first section rotates relative to the second section. The second section receives a force to drive the first section to move from below the second top surface to below the first top surface such that the rotating axis pressures the door.

A storage system includes a rim assembly and one or more magnets. The rim assembly is configured for attachment to a container to form a container assembly. The one or more magnets are positioned in the container assembly. An effective magnetic force exerted by the one or more magnets on a support surface from which the container assembly is suspended can be varied by adjusting a distance between the support surface and the one or more magnets.

A roasting/serving device has a base rack and a removably attachable raised rack. The assembled base and raised racks are held within a single pan or between a lower pan and an oppositely-oriented upper pan. The pan or pans containing the assembled base and raised racks is/are placed within a wire chafing stand with rotatable handles. The handles are rotatable to clamp together rims of the upper pan and lower pan.

The present invention relates to a multi-vacuum valve of a vacuum container. The present invention relates to a push button made from one selected from soft synthetic resin and soft silicone, comprising: a protruding annular rim protruding downward from the circumferential direction of the perimeter of a support part; a guide groove for the linear movement of a pressing part, which is recessed downward from a portion at which the outer circumferential end portion of the pressing part and the upper end of a height-varying part are in contact with each other; and a circular airtightness-maintaining rod for vertically moving downward by the pressing of the pressing part. The inflow/outflow of air, due to fine wear or damage caused by the cleaning of an airtight member, can be prevented and the inflow/outflow of air through a fine gap due to the distortion of the airtight member or gas pressure generated from food can be prevented, and thus a food storage period can be extended.
