fact enhanced and enlarged and modified by the heat sealed line 80 at the top of the bag in fig5 and the random directed openings 86 it should be understood that the bag 10 is formed from two similarly shaped essentially flat pieces of polymer material that are heat sealed at the periphery in a heat sealed line 80 a as seen in fig5 and 8 fig9 illustrates the cross sectional portion of the bag of fig5 taken on line 9 9 and it is depicted in the mode where there is water pressure within the manifold opening to form effectively an outwardly formed tubular configuration in the manifold itself as it is pressurized by the water entering in the direction of arrow 88 as shown in fig5 fig8 is simply showing the multiple openings 86 that are formed by the heat seal across the manifold forming heat seal line 80 as shown in fig5 fig6 and 7 show hook and loop attachments 100 and 102 which allow the total bag to be folded into the position from fig6 as indicated by the arrow 104 to the half position shown in fig7 this is convenient in certain times when the bag is not really full to allow a person to have a smaller bag than the full length bag of fig6 and it greatly facilitates keeping the bag from interrupting sleeping because of the smaller size thus it should be understood that the bag depicted in fig5 and 9 is a very simply made.
