Drinking Bag

Abstract

A drinking system comprising a pipe adapted to facilitate drinking from a first end of the pipe, a non-return valve unit connectable at a first end of the valve unit to a second end of the pipe, and a bag comprising at least a first layer and a second layer, the layers are connected so that fluid is containable in the bag between the layers, a slantable area on the first layer, facilitated by ribs embedded on the first layer, a first opening, in the slantable area, sealable by a cap, and a connector installed at a second opening, to which the pipe can be connected by the non-return valve, to facilitate drinking of fluids contained in the bag, the non-return valve is configured to enable fluids to flow from the bag to the pipe, while preventing flow of fluids back from the pipe to the bag.

1 . A drinking system comprising:
 a pipe adapted to facilitate drinking from a first end of the pipe;   a non-return valve unit connectable at a first end of the valve unit to a second end of the pipe; and   a bag comprising:
 at least a first layer and a second layer, the layers are connected so that fluid is containable in the bag between the layers; 
 a slantable area on the first layer, facilitated by ribs embedded on the first layer; 
 a first opening, in the slantable area, sealable by a cap; and 
 a connector installed at a second opening, to which the pipe can be connected by the non-return valve, to facilitate drinking of fluids contained in the bag when the bag contains fluids, the non-return valve is configured to enable fluids to flow from the bag to the pipe, while preventing flow of fluids back from the pipe to the bag. 
   
     
     
         2 . The drinking bag of  claim 1 , wherein when no fluid is contained between the layers, they are flattened against each other. 
     
     
         3 . The drinking bag of  claim 1 , wherein the slantable area is a hexagonal area defined by the ribs and by a top side of the bag 
     
     
         4 . The drinking bag of  claim 1 , wherein fluids are pourable into or out from the bag via the opening. 
     
     
         5 . The drinking bag of  claim 1 , wherein two of the ribs are each stretched between two neighboring edges of the bag. 
     
     
         6 . The drinking bag of  claim 5 , wherein each of the two ribs form another corner between an edge of the slantable area and corresponding edges of the bag. 
     
     
         7 . The drinking bag of  claim 6 , wherein each of the corners comprises a corresponding hole. 
     
     
         8 . The drinking bag of  claim 1 , comprising a hole for hanging or attaching of the bag, the hole is in a farthest edge of the bag opposite the opening. 
     
     
         9 . The drinking bag of  claim 8 , wherein the hole facilitates hanging of the bag so that the opening is directed downwards, so that complete draining of bag from fluid is enabled. 
     
     
         10 . The drinking bag of  claim 1 , wherein the slantable area is slantable along the ribs, so that the opening is tilted away from the rest of the respective layer. 
     
     
         11 . The drinking bag of  claim 11 , wherein when the slantable area is slanted along the ribs, fluids can be poured via the opening into or out from the bag. 
     
     
         12 . The drinking bag of  claim 1 , wherein the bag is cleanable by inserting a hand or a cleaning brush or a cloth into the bag via the opening. 
     
     
         13 . The drinking bag of  claim 1 , wherein the bag comprises folding lines going from the edges of the slantable area to a distal edge of the bag, thus providing a three-dimensional resilient structure to the bag when filled with fluids. 
     
     
         14 . The drinking bag of  claim 14 , wherein the structure enables holding of the bag with a hand and filling it with fluids, wherein the structure enables firm holding of the bag at the upper region of the bag without squeezing of the bag in its middle. 
     
     
         15 . The drinking bag of  claim 1 , wherein the opening constitutes a single opening both for filling and draining the bag.
