Abstract
Abstract The invention is an apparatus for controlling the temperature of a fluid contained in a receptacle. The fluid is accessible through an aligned container access port and receptacle access port. Heat exchange from the receptacle is minimized by a seal located about the container access port which conforms to the edges of the receptacle. The fluid may be heated or cooled by an appropriate temperature affecting means within the container.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
302 words
A reusable insulated container capable of accepting and holding a removable fluid receptacle with protruding edges containing a fluid and capable of controlling the fluid temperature, comprising: an upper member comprised of a top connected to an upper side and a bottom member comprised of a bottom connected to a bottom side, said upper member and said bottom member being detachably securable to each other, said top, upper side, bottom, and bottom side being sized and shaped to be capable of accepting and holding said receptacle within said container and to retard heat exchange between said receptacle and outside of said container; an access port located in said upper member which is capable of being aligned with an opening in said receptacle and is sufficiently large and sufficiently shaped to permit useful direct access to said fluid from outside of said receptacle and said container when aligned with said receptacle opening; a seal located on the lower face of said top, said seal having a first side, a second side, a first end and a second end, said first side conforming to said access port, said first end being closely adjacent to said upper side and one side of said access port to form a first notch between said upper side and said first end, said second end being closely adjacent to said upper side and the other side of said access port to form a second notch between said upper side and said second end, said first and second notches being shaped and sized to closely receive said protruding edge of said receptacle, said second side being sized and shaped to not obstruct said protruding edge and to permit said seal to closely abut the top of said receptacle and said protruding edge to fit within said first and second notches.
Claim 2
Dependent Claim
302 words
A reusable insulated container capable of accepting and holding a removable fluid receptacle with protruding edges containing a fluid and capable of controlling the fluid temperature, comprising: an upper member comprised of a top connected to an upper side and a bottom member comprised of a bottom connected to a bottom side, said upper member and said bottom member being detachably securable to each other, said top, upper side, bottom, and bottom side being sized and shaped to be capable of accepting and holding said receptacle within said container and to retard heat exchange between said receptacle and outside of said container; an access port located in said upper member which is capable of being aligned with an opening in said receptacle and is sufficiently large and sufficiently shaped to permit useful direct access to said fluid from outside of said receptacle and said container when aligned with said receptacle opening; a seal located on the lower face of said top, said seal having a first side, a second side, a first end and a second end, said first side conforming to said access port, said first end being closely adjacent to said upper side and one side of said access port to form a first notch between said upper side and said first end, said second end being closely adjacent to said upper side and the other side of said access port to form a second notch between said upper side and said second end, said first and second notches being shaped and sized to closely receive said protruding edge of said receptacle, said second side being sized and shaped to not obstruct said protruding edge and to permit said seal to closely abut the top of said receptacle and said protruding edge to fit within said first and second notches.
Claim 3
Dependent Claim
85 words
The invention of claim 1 wherein said access port has an upper portion and a side portion, said upper portion is located in said top and is sized and shaped to accomodate the nose of an average adult human when said receptacle is tilted to allow drinking from said receptacle through said access port, said side portion located in said upper side and is sized and shaped to accomodate the mouth of said human when said human drinks through said access port from said receptacle.
Claim 4
Dependent Claim
48 words
The invention as recited in claim 2 wherein said means for detachably securing said upper member to said bottom member comprises an upper inner sleeve portion of said upper side, said upper inner sleeve being closely insertable within an annulus of said bottom side and being adjustable therein.
Claim 5
Dependent Claim
60 words
The invention as recited in claim 3 wherein said bottom member further comprises a compartment member sized and shaped to receive a temperature affecting means of sufficient size and composition to change the temperature of the fluid; and wherein said container has a temperature affecting means within said compartment member which is capable of changing the temperature of said fluid.
Claim 6
Dependent Claim
24 words
The invention of claim 4 wherein said compartment member contains at least one support member to support said receptacle above said temperature affecting means.
Claim 7
Dependent Claim
20 words
The invention of claim 5 wherein said temperature affecting means is an endothermic reaction pack sufficient to cool said fluid.
Claim 8
Dependent Claim
21 words
The invention of claim 5 wherein said temperature affecting means is an exothermic chemical reaction pack sufficient to heat said fluid.
Claim 9
Dependent Claim
56 words
The invention of claim 5 wherein said temperature affecting means is self contained in heavy strength platic, is color coded to indicate whether said temperature affecting means is an endothermic or an exothermic reaction pack and is activated by breaking an internal barrier within said temperature affectuating means to initiate a chemical reaction between nontoxic chemicals.
Claim 10
Dependent Claim
30 words
The invention of claim 2 further comprising a flap member connected to said upper member which is capable of covering said access port to encapsulate said receptacle within said container.
Claim 11
Dependent Claim
75 words
The invention of claim 2 wherein said upper side has a continuous first inner flexible seal and said bottom side has a second inner flexible seal and a third continuous inner seal is positioned between said upper member and said bottom member, said first, second and third inner seals being capable of holding said receptacle in proper alignment within said container and of substantially preventing condensation within said container from leaking out of said container.
Claim 12
Dependent Claim
35 words
The invention of claim 2 wherein said means for detachably securing said upper member to said bottom member comprises said upper member fitting closely over the outside of said lower member and being adjustable thereon.
Claim 13
Dependent Claim
33 words
The invention of claim 2 wherein the bottom of said container is concave to minimize the surface area of said container having direct contact with flat surface said container may be set on.
