Embodiment Construction

[0037] Hereinafter, the present invention will be further described through embodiments in conjunction with the drawings.

[0038] Such as Figure 1~3 As shown, the disposable water bag embodiment is provided with a bag body 1, a bag plug 2 and a plug cap 3.

[0039] The bag body 1 is composed of an outer layer, a middle layer and an inner layer. The outer layer is a PET film with a thickness of 12 μm; the middle layer is a nylon film (PA) with a thickness of 15 μm; and the inner layer is a PE film with a thickness of 80 μm.

[0040] The edge of the bag body 1 is the heat-sealed adhesive edge, and the right angle of the bag body 1 is 45° heat-sealed and bonded chamfer 1-1; the upper part of the bag body 1 is the bottleneck 1-2 of the bag mouth, and the bottom of the bag body 1 (Outside the adhesive side) is provided with water bag hanging holes 1-3; the bag body 1 is folded into a 4-petal symmetrical structure by a bag making machine. In this embodiment, the edge bonding width of t...

Abstract

The invention relates to a water accommodating tool, and provides a disposable water bag, which can prevent a water body in a bucket from being influenced by the outside environment, and a processing method for the disposable water bag. The disposable water bag is provided with a bag body, a bag plug and a plug cap, wherein the bag body is provided with an outer layer, a middle layer and an inner layer. The processing method comprises the following steps of: compounding a polyethylene terephthalate (PET) film and a protactinium (PA) film by glue, and solidifying the compound at constant temperature to obtain a PET and PA compound film; compounding the PET and PA compound film and a polyethylene (PE) film by glue, and solidifying to obtain a PET, PA and PE compound film; making a bag by using the compound film by a bag making machine to form the bag body; performing injection molding to make the bag plug, and performing secondary injection molding on the outer wall at the lower end of the bag plug to form a compound layer; thermally adhering the bottleneck of the bag opening of the bag body to the outer wall at the lower end of the bag plug; filling water, sealing compactly, and detecting whether the water bag leaks water by using a pressure machine; performing injection molding on a threaded body and a movable plug of the plug cap, assembling the threaded body and the movable plug to form a whole, and arranging a sealing gasket; and folding the disposable water bag, putting into a packaging box, and matching the plug cap.

Description

Technical field [0001] The invention relates to a water holding appliance, in particular to a disposable water bag and a processing method. Background technique [0002] At present, the main water containers for drinking fountains are PC barrels, which can be used repeatedly after recycling and cleaning. The empty PC bucket occupies a large space, which brings inconvenience to transportation. The PC bucket must be ventilated with the outside air to maintain the pressure in the air in the PC bucket so that the remaining water in the PC bucket can flow out smoothly. The air entering the PC bucket can easily pollute the water in the bucket. Especially in the environment where the outside air is relatively polluted such as hospitals and outdoor operations, the water in the PC bucket is easily polluted. [0003] Chinese patent CN2853663 discloses an improvement to the structure of disposable water storage bags for drinking fountains. It mainly solves the technical problems of directl...
