Abstract
The invention discloses a double-layer medical infusion bottle and a manufacturing method thereof. The double-layer medical infusion bottle comprises a double-layer flat infusion bottle body, an inner layer made of polypropylene material and used for keeping infusion stability, and an outer layer made of ester type co-polymer material and capable of being directly used for printing labels. The infusion bottle is good in safety, good in barrier property and good in infusion performance. The manufacturing method for the double-layer medical infusion bottle includes that using a double-die head extrusion die to extrude in one die and blow air. The technique is simple and advanced, and the double-layer medical infusion bottle is formed in one die; the manufacturing method is suitable for the double-layer medical infusion bottle production, and the manufactured infusion bottle conforms to infusion requirements.
Description
Technical field
The present invention relates to the field of medical plastic packing container, particularly relate to a kind of can the double-deck medical infusion bottle of printed label and manufacture method thereof.
Background technology
At present, medical infusion plastic bottle has Polypropylene bottle and blended transfusion bag two type.Simply introduce content and its weak point of these two kinds of infusion vessels below:
Plain polypropylene plastic bottle, adopt notes stretch blow moulding process more, is applicable to the bottle that bottle wall is thin; This production technology characteristic, for stretch to pipe, causes bottle wall very thin, and especially to the bottle of flat, the large direction that stretches is thinner, and bottle wall thickness is thin seriously uneven.Oxygen and moisture-vapor transmission are comparatively large, can only pack common transfusion; Still there is the defect of vial in infusion model, need to pass into air in bottle, harmful antibacterial and microgranule enter, and thus cause the possibility that bottle inner liquid medicine pollutes, and plain polypropylene infusion bottle adopts the mode of pasting adhesive label simultaneously, adhesive label scribbles adhesive, containing large amount of organic matter on adhesive, the risk of oriented medicinal liquid migration, simultaneously, because the sterilizing after liquid drug and lamp inspection operation are without label, easily there is the risk of mixed medicine.Polypropylene material is direct colour print not easily.Therefore the development of plastic bottle is restricted.
Blend composition infusion bottle, as much adopts note stretch blow moulding process, and this production technology characteristic, for stretch to pipe, causes bottle wall very thin, and especially to the bottle of flat, the large direction that stretches is thinner, and bottle wall thickness is thin seriously uneven.Oxygen and moisture-vapor transmission larger, can only pack limited common transfusion, this infusion bottle, owing to adopting PP and styrene-ethylene/butylene-styrene block copolymer blending technology, makes polypropylene material hardness lower, tool, in use without the need to air inlet, adopts atmospheric pressure transfusion.Co-blend polypropylene infusion bottle adopts the mode of pasting adhesive label simultaneously, adhesive label scribbles adhesive, containing large amount of organic matter on adhesive, the risk of oriented medicinal liquid migration, simultaneously, because the sterilizing after liquid drug and lamp inspection operation are without label, easily there is the risk of mixed medicine, co-blend polypropylene material also not easily direct colour print.
Summary of the invention
The invention provides a kind of double-deck medical infusion bottle and manufacture method thereof, by arranging the infusion bottle of double bottle Rotating fields and providing corresponding production method, overcome PP or PP and the blended shortcoming of styrene-ethylene/butylene-styrene block copolymer, in conjunction with both advantage, and adopt the technique of extrusion blow more can play the performance of material, solve produced problem in background technology.
The object of this invention is to provide a kind of double-deck medical infusion bottle and manufacture method thereof, the transfusion bottle of a kind of medical infusion bottle mainly double-deck flat shape, transfusion bottle shoulder erects; Double-decker mainly polyacrylic internal layer keeps skin that is stable and lipin polymer to be easy to printed label; Be outside equipped with hanging ring in the middle of the bottom of transfusion bottle, the surrounding of the bottom hung ring of transfusion bottle arranges four feets.
Further improvement is: the polypropylene of internal layer and the mass ratio (60 ~ 80) of outer field lipin polymer: (20 ~ 40).
Further improvement is: skin can adopt high barrier material, for packing the oxidizable transfusion of aminoacid, fat milk and so on.
A manufacture method for double-deck medical infusion bottle, comprises the following steps:
Step one: by the barrel making the polypropylene material of internal layer, outer field lipin polymer material is respectively charged into the extrusion die of corresponding internal layer and outer field extruding and blowing machine;
Step 2: preheating is carried out to extruding and blowing machine and blowing mould, by step one material heating and melting respectively, temperature is 220 ~ 260 DEG C, after melting, is extruded respectively form the tubulose embryo that internal layer is polypropylene material, skin is lipin polymer material by two extrusion die heads of extruding and blowing machine;
Step 3: the tubulose embryo of bilayer step 3 formed sends into the interior shape bottle blowing mould identical with tubulose embryo, closes afterwards;
Step 4: remove the unnecessary tubulose embryo of blowing mould upper and lower with heating plate;
Step 5: tubulose embryo passes into compressed air and carries out bottle blowing in blowing mould, air blowing air pressure is 1.0 ~ 1.5MPa, and tubulose embryo cooling and shaping under air pressure after blowing, makes the infusion bottle of required bilayer;
Step 6: carry out punching bottom the infusion bottle of bilayer step 5 obtained, makes link.
Step 7: the infusion bottle of bilayer step 6 obtained carries out printed label.
Further improvement is: the polypropylene of described internal layer and the mass ratio (60 ~ 80) of outer field lipin polymer: (20 ~ 40).
Beneficial effect of the present invention: by arranging totally-enclosed double-decker, internal layer is polypropylene, and its security and stability is good, and skin is lipin polymer layer, and its insulating is good, high temperature resistant, be easy to painted, can carry out printed label to infusion bottle; The design of double-deck soft infusion bottle, makes whole infusion bottle security performance better; Be integrated hanging ring in the bottom of transfusion bottle, without the need to secondary welding link, make transfusion production minimizing one weld-ring operation; Whole transfusion bag body is flat shape, and shoulder erects, such design is convenient to that infusion process is without the need to air inlet, and medicinal liquid more at the uniform velocity can carry out venous transfusion; Four-point supporting foot is arranged at the bottom of bag, so just uprightly can stand and be convenient to dosing in the plane; The technique of this transfusion bag adopts to be extruded, the technique of blowing, this technique employing Double-mold-head extrusion die carries out Integratively and is extruded into embryonic type, technique is simple, require high without the need to complexity as noting the production of stretch blow, overcome the fault of construction of common plastics bottle and PP TYPE leakage, and make infusion bottle meets the requirement of transfusion, more can play the performance of material compared with technique before.
