Abstract
The Invention is a container for holding a liquid, such as a single-use beverage bottle. Gas-filled annular rings appear on a portion of the surface of the bottle. The air-filled annular rings partially insulate the bottle and slow the rate of heat transfer to and from the contents of the bottle. The air-filled annular rings also serve to provide a gripping surface to aid in the handling to the bottle by a user.
Claims6
A single-use beverage bottle, the bottle comprising:
- a. a container adapted to hold the beverage, said container having a wall, said wall having a wall outer surface;
- b. a plurality of annular rings, said plurality of annular rings engaging said wall outer surface;
- c. a plurality of annular reinforcing members, each of said annular reinforcing members engaging said wall outer surface and one of said annular rings, each of said annular reinforcing members being adapted to resist deformation of one of said annular rings during handling of said container;
- d. a plurality of interior volumes, each of said plurality of said interior volumes being defined by one of said annular rings and said wall outer surface;
- e. a gas filling each of said interior volumes, each of said interior volumes being sealed such that said gas is confined within said each of said interior volumes, said gas having a pressure, each of said annular rings having a preselected shape, said pressure being selected to be sufficiently greater than an ambient air pressure such that each said annular ring substantially maintains said pre-selected shape during handling of the single-use beverage bottle.
2 more elements
An apparatus for holding a liquid, the apparatus comprising:
- a. a plurality of annular rings, each of said plurality of annular rings defining a one of a plurality of interior volumes, each said interior volume containing a gas;
- b. a container, said container adapted to contain the liquid, said container having a wall, said wall defining a wall outer surface, said wall outer surface adapted to receive each of said plurality of annular rings, each of said plurality of annular rings engaging said wall outer surface, wherein each of said annular rings has a pre-selected shape, said gas contained in each of said plurality of interior volumes of said annular rings has a pressure, said pressure is selected to be sufficiently greater than an ambient air pressure such that said annular ring maintains said pre-selected shape during handling of the apparatus.
