Bottle warmer or cooler

Claim 2

A portable device for selectively heating or cooling a bottle by heat exchange with a fluid, comprising: A. a container for holding said bottle in contact with said fluid, said container having an enclosing wall upstanding from a closed bottom end thereof and having an open, upper end thereof; B. a platform means positioned within said container above said bottom end for supporting the bottle in spaced relation thereto, said platform means dividing the interior of the container into an upper chamber for holding said bottle and a lower chamber between said platform means and said bottom end for distribution of said fluid, said platform means having at least one passageway oriented upwardly therethrough for directing upward passage of said fluid from said lower chamber into said upper chamber to contact said bottle during upward flow of the fluid through the container; and C. a conduit means communicating with said lower chamber and defining a flow path separated from said upper chamber for supplying said fluid to said lower chamber, said conduit means including an upstanding tube positioned within said container, said tube having an opening formed at the upper end thereof for entry of fluid downwardly flowing through said tube into said lower chamber.

Claim 3

The device of claim 1 in which said tube extends downwardly within said upper chamber and through an aperture formed in said platform means, said tube having an outlet formed at the lower end thereof communicating with said lower chamber for discharge of said fluid therein.

Claim 4

The device of claim 1 in which said platform means includes support means for said bottle, said support means being aligned with said passageway for direction of said upwardly flowing fluid therethrough against the bottom of said bottle.

Claim 5

The device of claim 3 in which said passageway is defined by a generally circular hole, said support means including a cruciform-configured stage positioned diagmetrically across said hole, said stage having a portion thereof elevated from the upper surface of said platform for supporting the bottom of said bottle thereabove.

Claim 6

The device as claimed in claim 1, further including guide means for holding said bottle in alignment with said passageway.

Claim 7

The device of claim 5, in which said guide means includes a plurality of brackets positioned within said upper chamber for engagement with an upstanding surface of the bottle.

Claim 8

The device of claim 6 in which each said bracket includes a bottom end secured to said platform means.

Claim 9

The device of claim 6 in which at least one said bracket includes an upstanding member positioned inwardly from displaceable outwardly toward said wall when said bottle is inserted into said container.

Claim 10

The device as claimed in claim 8 in which said bracket includes an N-shaped portion being resiliently formed for compression of said N-shape during said outward displacement.

Claim 11

The device of claim 8 in which at least one of said brackets includes an upper end thereof slidably engaged with the interior surface of said wall to enable upward sliding of said end during said outward displacement.

Claim 12

The device of claim 1 further including a plurality of brackets positioned within said upper chamber for engagement with an upstanding surface of the bottle, wherein one of said brackets includes an upper end thereof slidably engaged with the exterior surface of said tube.

Claim 13

The device of claim 1 in which said platform means is removably secured within a circumferential slot form in the interior surface of said wall.

Claim 14

The device of claim 3 in which said platform means has at least a second passageway oriented upwardly therethrough and spaced from said first mentioned passageway for directing upward passage of said fluid against an upstanding surface of said bottle.

Claim 15

A portable device for selectively heating or cooling a bottle by heat exchange with a fluid, comprising: A. a container for holding said bottle in contact with said fluid, said container having an enclosing wall upstanding from a closed bottom end thereof and having an open, upper end thereof; B. a platform means positioned within said container above said bottom end for supporting the bottle in spaced relation thereto, said platform means dividing the interior of the container into an upper chamber for holding said bottle and a lower chamber between said platform means and said bottom end for distribution of said fluid, said platform means having at least one passageway oriented upwardly therethrough for directing upward passage of said fluid from said lower chamber into said upper chamber to contact said bottle during upward flow of the fluid through the container; C. a conduit means communicating with said lower chamber and defining a flow path separated from said upper chamber for supplying said fluid to said lower chamber; and D. at least one guide bracket positioned within said upper chamber for engagement with an upstanding surface of the bottle, said bracket including a member positioned inwardly from the interior surface of said enclosing wall and resiliently displaceable outwardly toward said wall when said bottle is inserted into said container.

Claim 16

A portable device for selectively heating or cooling a bottle by heat exchange with a fluid, comprising: A. a container for holding said bottle in contact with said fluid, said container having an enclosing wall upstanding from a closed bottom end thereof and having an open, upper end thereof; B. a platform means positioned within said container above said bottom end for supporting the bottle in spaced relation thereto, said platform means dividing the interior of the container into an upper chamber for holding said bottle and a lower chamber between said platform means and said bottom end for distribution of said fluid, said platform means having at least one passageway oriented upwardly therethrough for directing upward passage of said fluid from said lower chamber into said upper chamber to contact said bottle during upward flow of the fluid through the container; C. a conduit means communicating with said lower chamber and defining a flow path separated from said upper chamber for supplying said fluid to said lower chamber; and D. at least one guide bracket positioned within said upper chamber for engagement with an upstanding surface of the bottle, said bracket including a member positioned inwardly from the interior surface of said enclosing wall and resiliently displaceable outwardly toward said wall when said bottle is inserted into said container.

Claim 17

The device of claim 14 in which said bracket includes a bottom end secured to said platform means.

Claim 18

The device as claimed in claim 14 in which said bracket includes an N-shaped portion being resiliently formed for compression of said N-shape during said outward displacement.

Claim 19

The device of claim 14 in which said bracket includes an upper end thereof slidably engaged with the interior surface of said wall to enable upward sliding of said end during said outward displacement.
