New application of spring bottle blowing process

Victor machinery co., LTD in jiangsu province as a pharmaceutical packaging solution provider, this kind of other products for the market research and the analysis of existing technology, found that spring bottle besides different shape with normal container, also has its special requirements in functional aspects: 1. The transparency, because need to be mixed solution and warm water after shake, patients need to look inside the bottle and so on has certain transparency requirements; 2. The flexibility, because spring bottle need to manually squeeze bottle inside the liquid into the affected area, repeated several times to get net solution, need the bottle in guaranteed to forcibly springback decrease as far as possible under the condition of patients; 3. Sealing, because is part of the spring bottle filling liquid in bottles in advance, have a certain request for sealing, and because most of the spring to ensure flexibility will adopt more soft LDPE, at the same time the bottle wall thickness will be thinner, in some cases will appear to the naked eye can’t see the small pores, once appear porosity, will lead to failure or deterioration of liquids, resulting in loss of patients and manufacturer. With the traditional craft production spring bottle on the market at present has many disadvantages: such as exists at the bottom of the fins, have cut marks, poor, poor mouth thread sizes, sealing, uneven thickness, the joint line defect of the coarse appearance or functions such as the most important thing is that need a second processing, it is difficult to conform to the requirements of the GMP production environment don’t contact with hands.
