Description

多层聚对苯二甲酸乙二醇酯啤酒瓶
技术领域：
本实用新型涉及灌装饮料的容器，尤其是啤酒瓶。
技术背景：
现有的啤酒瓶常采用玻璃制成，但玻璃瓶笨重而且爆炸事故屡有发生，迫切需要一种新型的包装瓶来取代玻璃瓶，金属铝罐因成本高不能成为经济的包装材料，聚对苯二甲酸乙二醇酯(PET)作为一种新型的包装材料与玻璃相比具有重量轻、强度大、韧性好、不易破碎、携带方便、易于制成各种形状和规格的优点，又由于该材料可以回收再生，已被世界环境保护组织推荐为优选包装材料，但是这种材料用于制造啤酒瓶需要解决防氧渗透性能差的问题，因为啤酒对氧气非常敏感，一般在啤酒容器中增加1PPM氧气，啤酒就会变味。
发明内容：
本实用新型要解决的技术问题是从瓶体的构造上弥补聚对苯二甲酸乙二醇酯瓶防氧渗透性能差的问题。本实用新型的技术方案是瓶体由三层构成，瓶体的内层与外层采用聚对苯二甲酸乙二醇酯，在瓶体内外层之间有隔氧材料层。由于瓶体采用多层构成并夹有隔氧层，因此能达到防氧渗透，保持啤酒风味和储存的要求，而且具有重量轻、强度大、韧性好、不易破碎、携带方便、易于制造等优点。
附图说明：
附图表示的是本实用新型瓶体纵剖面的示意图，图中1表示瓶体的内层，2表示瓶体的外层，3表示隔氧层
具体实施方式：
实现本实用新型的最好方式是利用多层注塑技术，即利用三个注塑枪同时分别将聚对苯二甲酸乙二醇酯、隔氧材料和聚对苯二甲酸乙二醇酯均匀注入瓶坯模具，并采用这种瓶坯吹塑成形即可成为三层复合瓶体的聚对苯二甲酸乙二醇酯啤酒瓶。隔氧材料可采用结晶型芳香族新型尼龙(NMXD6)或乙烯—乙烯醇共聚物(EVOH)，经试验在瓶坯中均匀注入3％-5％EVOH隔热材料制成的多层聚对苯二甲酸乙二醇酯啤酒瓶可使啤酒保鲜4个月以上。
