Description
Technical field
The present invention relates to plastic bottle manufacturing technology field more particularly to a kind of hanging ring integrated transfusion bottle and its manufacturing methods.
Background technique
Currently, bottle body (bag body) is to separate with hanging ring, and hanging ring is welded on the market in conventional infusion bottle (infusion bag)
The defect of the bottom of bottle body (bag body), this kind of infusion bottle (infusion bag) is:
One, due to being welding between hanging ring and infusion bottle (infusion bag), there is conjunction between hanging ring and infusion bottle (infusion bag)
Die slot gap causes the firmness between hanging ring and infusion bottle (infusion bag) low, is easy to happen obscission, easily causes danger；
Two, infusion bottle (infusion bag) and hanging ring need two molds to be produced, and cause that the production cost increases, production cost
It improves；
Three, infusion bottle (infusion bag) and hanging ring during the welding process, are carried out by the way of human weld
, the degree of automation is low, needs a large amount of personnel's auxiliary operations, increases quality risk, increase cost of labor；
Four, infusion bottle (infusion bag) and hanging ring are fixed by the way of heating welding, be easy to cause environmental pollution.
Summary of the invention
The invention solves the above-mentioned problems of the prior art, a kind of hanging ring integrated transfusion bottle and its manufacturer are provided
