Abstract

一种由盖体,弹簧和塞块所构成的无回弹塑料盖,其结构特点是在盖体的侧面加工的挤出孔,盖体内装有弹簧和塞块。使用时管内物料挤压推动塞块移动,物料从挤出孔出来,塞块靠弹簧的压力自动回位,封住挤出孔和管出口,达到管内不进空气目的。本实用新型具有结构简单,使用方便等优点。

Description

无回弹塑料盖
本实用新型属于日常生活用品,是涉及一种塑料盖的改进。
目前在与牙膏、药品、化妆品等包装管相配套使用的塑料盖一般采用螺纹相连接,这种塑料盖没有防止空气侵入的结构,使用过程中空气进入管内,使有些软管产生回弹现象,也使管内的物质产生氧化作用。
本实用新型的目的是提供一种使空气无法进入管内,使塑料软管不回弹的无回弹塑料盖。
本实用新型的技术方案是在塑料盖体的侧面加工有挤出孔,用于管内物料的挤出,塑料盖体内装有弹簧和塞块,盖体通过螺纹和管体连接;本实用新型的特征是在塑料盖体的侧面加工有挤出孔,盖体内装有弹簧,和弹簧相连处有塞块,盖体和管体螺纹相连。
本实用新型的工作原理是管体内的物料挤出时由于物料的压力挤压塞块向上移动,物料经挤出孔出来,当不挤压时塞块在弹簧作用下封住挤出孔和管的出料口,达到空气无法进入管内防止管体回弹的目的。
本实用新型的积极效果是由于塑料盖体内采用弹簧来控制塞块移动封住挤出孔和出料孔,使空气无法进入,达到管体无回弹作用;并具有结构简单、实用等优点。
附图1是本实用新型的结构剖视图。
在图1可清楚地表示在管体1上通过螺纹连接有盖体5,在盖体5的侧面加工有挤出孔2,在盖体5内装有弹簧4,在弹簧4下装有塞块3,塞块3可加工成球型、片型或锥型。
