Abstract

Abstract This invention provides a table air pot for keeping hot or cold liquid comprising a wide mouth vacuum-insulated bottle housed in an outer casing and supported by upper and lower supporting means respectively fixed on the top and bottom ends of the outer casing. The lid of the table air pot includes in combination a bellow-type pump device for pumping up the liquid contained in the bottle into a drink cup while the air pot stands upright on a table, and a plug fixed to the bottom of the pump device for closing the bottle when the lid in its closed position. The tube for discharging the liquid from the bottle in response to the operation of the pump device is fixed on the upper supporting means for the bottle and is physically separated from the plug of the lid. Thus, the table air pot according to this invention can become ready to be filled with liquid by a single operation of opening the lid without need of removing the liquid tube.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 211 words
A table air pot comprising: an elongate outer casing having a top end and a bottom end; a lower supporting means mounted at said outer casing bottom end; an upper supporting means mounted at said outer casing top end and including an annular member having a central opening, having a circumferential wall, and having a liquid outlet outwardly projected from said circumferential wall; a vacuum-insulated wide mouth bottle housed in the outer casing and supported by said upper and lower supporting means, the upper supporting means central opening connected with the wide mouth of the bottle and having substantially the same size diameter as the diameter of said wide mouth, and said liquid outlet adapted to be connected into communication with the inside of the bottle; a liquid tube having one end connected to the liquid outlet and other end extending into the bottle downward to the adjacency of the bottom of the bottle; a lid pivotally connected onto the upper supporting means for the bottle in order to open and close the opening of the upper supporting means; a bellow-type pump device fixed inside the lid; and a plug fixed to the bottom of the pump device for closing the wide mouth bottle when the lid in its closed position.
Claim 2
Dependent Claim 211 words
A table air pot comprising: an elongate outer casing having a top end and a bottom end; a lower supporting means mounted at said outer casing bottom end; an upper supporting means mounted at said outer casing top end and including an annular member having a central opening, having a circumferential wall, and having a liquid outlet outwardly projected from said circumferential wall; a vacuum-insulated wide mouth bottle housed in the outer casing and supported by said upper and lower supporting means, the upper supporting means central opening connected with the wide mouth of the bottle and having substantially the same size diameter as the diameter of said wide mouth, and said liquid outlet adapted to be connected into communication with the inside of the bottle; a liquid tube having one end connected to the liquid outlet and other end extending into the bottle downward to the adjacency of the bottom of the bottle; a lid pivotally connected onto the upper supporting means for the bottle in order to open and close the opening of the upper supporting means; a bellow-type pump device fixed inside the lid; and a plug fixed to the bottom of the pump device for closing the wide mouth bottle when the lid in its closed position.
Claim 3
Dependent Claim 44 words
The table air pot as defined in claim 1 wherein said tube is mounted in said upper supporting means and wherein the undersurface of said plug is formed with a recess for accommodating said tube when said lid is in the closed position thereof.
Claim 4
Dependent Claim 41 words
The table air pot as defined in claim 1 or 2 wherein the liquid tube is connected to the liquid outlet spout via a spout channel and a bend extending through the wall of the upper supporting means for the bottle.
Claim 5
Dependent Claim 113 words
The table air pot as defined in claim 1 or 2 wherein the liquid tube is connected to the liquid outlet spout via a spout channel and a bend, the spout channel being formed by a tubular member one end of which opens toward the outlet spout and the other end is provided with an enlarged portion having an opening for connecting the bend, and in that portion of the wall of the upper supporting means for the bottle facing the outlet spout, there is formed a slot for snugly receiving the enlarged portion of the spout channel so as to fix the spout channel as well as the liquid tube in position.
