The purpose of this utility model is achieved through the following technical solutions.The packaging bag of potable water disposable soft was made up of lid, intake-outlet, bag and the bag end, one end of water inlet and bag links, the other end of the bag end and bag links, lid covers on intake-outlet, bag, the bag end and intake-outlet all use transparent non-poisonous plastic sheeting to make, have one to enclose firmly at water inlet mouth end, the thickness at 20～30mm place of close intake-outlet mouth end is thicker slightly than the thickness at all the other positions.

The utility model is compared with the packaging hard transparent plastic bucket of present barreled drinking water, have because made from plastic sheeting, so drunk to the water the bag and no longer entered air (knowing from experience slowly flat) because of water flows out back pkt. from bag from filling water, and can not be polluted, guarantee that the water in the bag reaches the sanitary index of potable water always, the person's that is of value to drinking-water health.Whether totally this packing does not re-use after once using, do not have cleaning problem, is unkitted that water is collapsible before, volume is little, convenient transportation.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is described in further detail.In the accompanying drawing: the 1-lid; The 2-intake-outlet; The 3-bag; At the bottom of the 4-bag.Can make the oblong base substrate that has only a mouth earlier with the material (as nontoxic vinyl chloride, polyethylene etc.) of making the transparent non-toxic plastics film in force, a blow molding in the mould of potable water disposable soft packaging bag then, intake-outlet 2 holds in the 20-30mm scope suitable thicker near mouth in the blowing process, all the other positions are a little thin, its thickness can bear the water of adorning 20kg with intensity, and not breaking in shipment is as the criterion.Once make at this manufacture method intake-outlet 2, bag 3 and the bag end 4.Also can make intake-outlet 2, bag 3 and the bag end 4 respectively, adopt pressure sintering or bonded process that it is unified into a soft packaging bag then.These two kinds of methods are good with the method for a blow molding.The structure of lid 1 can adopt the identical structure of the bottle closure of rubber on the infusion bottle, can certainly adopt the structure of other form.
