Embodiment 1

[0025] Such as figure 1 , 2 As shown in and 3, this embodiment provides a double-layer medical infusion bottle and a manufacturing method thereof. A double-layer medical infusion bottle is mainly a flat-shaped infusion bottle body 1 with a double-layer structure, and the shoulder of the infusion bottle body 1 stands up , The bottleneck is trapezoidal; the double-layer structure is the inner layer 2 of polypropylene and the outer layer 3 of lipid copolymer. The bottom of the infusion bottle body 1 is provided with an integrated punching suspension ring 4 outside the bottom of the infusion bottle body 1. Four supporting feet 5 are arranged around the suspension ring 4; the mass ratio of the polypropylene of the inner layer 2 to the lipid copolymer of the outer layer 3 is 60:40, and the outer layer can be made of high-barrier materials for packaging amino acids and fat emulsions. Such as easy to oxidize infusion.

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 [0001] The invention relates to the field of medical plastic packaging containers, in particular to a double-layer medical infusion bottle capable of printing labels and a manufacturing method thereof. Background technique [0002] At present, there are two types of medical infusion plastic bottles: polypropylene plastic bottles and blended infusion bags. The following briefly introduces the contents of these two infusion containers and their shortcomings: [0003] Ordinary polypropylene plastic bottles use injection stretch blow molding technology, which is suitable for bottles with thin bottle walls. The production process is characterized by stretching the tube blank, resulting in very thin bottle walls, especially for flat bottles, which have large stretches. The direction is thinner, and the bottle wall thickness is seriously uneven. The oxygen and water vapor transmission rate is relatively high, so it can only be packaged for ordinary infusion; in terms of ...
