DETAILED DESCRIPTION OF THE INVENTION
Referring to the drawings in detail wherein like elements are indicated by like numerals, there is shown a water on demand bag 1. The bag 1 has a front 2, rear 3, top 4, bottom 5, two opposite sides 6, an exterior surface 7, and an interior 8 defined by said bag front, rear, top, bottom and sides. The bag sides 6 are formed into gussets for bag expansion. The bag bottom 5 may be formed into a general “V” shape to allowing maximum access to the bag contents.
The bag top 4 has a reinforced aperture 9 formed therein, through which a drinking tube 10 is inserted and extending into the bag interior 8 along the front 2 or rear 3 near to the bag bottom 5. The drinking tube 10 is comprised of an elongated body 13 with two open ends, one end 11 positioned within the bag interior 8 and the other end 12 protruding external from the bag interior. The drink tube body portion 14 within the bag interior 8 may be fused centrally along the bag front 2 or rear 3.
The bag front 2 has two handle straps 20 attached to the bag exterior surface 7 and folded one along the other. Each handle strap has two ends, one end 21 attached to the bag front 2 near to a side 6 and the other end 22 releasably attached to the opposite handle strap. Each strap fee end 22 has an adjacent adhesive area 23 covered by a removable paper tab 24.
The bag top has a tear-down notch 30 formed therein, said notch 30 adapted to being torn open for full access to the contents of the bag interior 8. This permits the bag contents to be poured onto a wound or other area needing cleaning, or into a container. See FIG. 9.
The drinking tube external end 12 may terminate in a bite and drink feature 16. The drinking tube 10 may also have a cap 15 attached to its body 13 and removably inserted into the drinking tube exterior end 12. See FIGS. 11 and 13.
As may be seen most clearly in FIGS. 1 and 12, the bag 1 is adapted to being attached about the torso 40 of a user, said bag attached by means of the handle straps 20 and joined together by means of the adhesive patches 23. The drinking tube exterior end 12 extends to the user's mouth (not shown) providing access to the bag contents.
A purification capsule 50 may be attached to one of the interior walls of the water bag, either directly or inserted into a mesh patch 51 attached to one of the water bag interior walls. The capsule 50 is adapted to interact with water. Once the water bag 1 is filled with water, the capsule decontaminates the water. See FIG. 14.
The water bag bottom 5 may have an aperture 17 sealable by means of an adhesive strip 18. This is intended to be a one-time sealable aperture. The end user would have the means for opening the water bag bottom, filling the bag with water, and then sealing the bottom.
It is understood that the above-described embodiment is merely illustrative of the application. Other embodiments may be readily devised by those skilled in the art which will embody the principles of the invention and fall within the spirit and scope thereof.
