Abstract

A water bag is provided with an expanse of material extending across a lower portion of a bag wall to provide a pocket into which may be inserted a heat pack or a heat sink. Conduits are provided on the interior surface of the bag wall adjacent the pocket with bag contents flowing through the conduits and heated by the heat pack in place on the bag exterior. A bag outlet defines a mixing chamber which receives bag contents from multiple passageways. A valve regulates discharge flow from the bag.

Claims

1. A portable water bag including,

a bag having opposite ends and having an inlet and an outlet each adjacent a respective one of said opposite ends, said bag including a wall member and a retainer located proximate the wall member to define a pocket for reception of a heat source, said retainer being an expanse of material fused to said wall member,

conduit means on the bag interior through which water flows from said inlet to said outlet, said conduit means partially embodied in said wall member.

2. The portable water bag claimed in claim 1 wherein said conduit means includes primary and secondary passageways.

3. The portable water bag claimed in claim 1 wherein said bag includes a second wall member, said conduit means embodied in fused portions of said wall member and said second wall member.

4. The portable water bag claimed in claim 3 wherein said conduit means includes primary and secondary passageways and a mixing chamber in communication with said passageways.

5. A portable bag for the storage of a liquid, said bag including,

a wall member defining a bag having opposite ends,

a retainer proximate the wall member to define a pocket, said wall member and retainer being of fusible material,

a bag inlet and an outlet each adjacent a respective one of said opposite ends,

an insert for said pocket for altering the temperature of the liquid, and

said pocket normally having a cross sectional dimension less than a like cross sectional dimension of said insert to cause displacement of said wall member and said retainer upon insertion of said insert into the pocket to ensure biased contact of the insert with said wall member.

6. The bag claimed in claim 5 additionally including conduit means on the bag interior through which liquid flows from said inlet to said outlet.

7. The bag claimed in claim 6, wherein said conduit means are partially embodied in said wall member.

8. The bag claimed in claim 6, wherein said conduit means includes first and second passageways of dissimilar configuration.

9. A bag for liquids comprising,

a bag having walls defining passageways for the liquids, and opposite ends,

an inlet and an outlet each adjacent a respective one of said opposite ends,

said passageways in communication with said inlet and said outlet,

an expanse of flexible material having edges fused to at least one of said walls, said expanse of material offset from said one of said walls to insertably receive a heat source and to urge the heat source into abutment with said passageways to impart heat thereto.
