Description

无油污防伪瓶塞
本实用新型涉及到一种用于液体特料贮存所用的封口,特别是无油污防伪瓶塞。
中国专利(ZL94226422.3)提供了一种洁净瓶塞,由瓶盖和回流塞组成,回流塞上有颈塞、出口、外凸沿和沟槽,出口上有″V″形缺口,这种洁净瓶塞虽然能有效地解决瓶塞外被流出液体污染的问题,但其不具有防伪功能,易被假冒产品生产者收购瓶体而生产假冒产品。
本实用新型的目的是提供一种既能防止瓶体外被流出液体污染,又能防伪的无油污防伪瓶塞。
本实用新型的技术方案是这样来实现的:无油污防伪瓶塞,由瓶盖和回流塞组成,回流塞与瓶盖活接,回流塞上有出口、外凸沿、颈塞和沟槽,沟槽底部为一倾料面,其特征是在回流塞的颈塞外有外封罩,外封罩上的下端连有卡环,防伪拉片与出口相连,拉掉防伪拉片后,在出口上就开有一个回流口。
本实用新型与现有技术相比,既能防止瓶体外被流出的液体污染,又具有防伪功能,且还有结构简单,使用方便卫生等优点,是极为理想的用于液体物质贮存的容器封口。
图1为本实用新型的结构示意图;
图2为图1的仰视图;
图3为本实用新型回流塞拉掉防伪拉片的使用状态图。
以下结合附图所示实施例对本实用新型作进一步描述。
如附图所示:无油污防伪瓶塞,由瓶盖(1)和回流塞(2)组成,回流塞(2)与瓶盖(1)螺纹连接,回流塞(7)上有出口(3)、外凸沿(4)、颈塞(5)、沟槽(6)、外封罩(7);沟槽(6)底部为一倾斜面,外封罩(7)连在颈塞(5)外,其下端连有卡环(8),防伪拉片(9)与出口(3)相连,拉掉防伪拉片(8)后,在出口(3)上就开有一个回流口(10)。为了防止倒出的液体流速过快,在颈塞(5)内环面上连有阻流环(11)。回流塞(2)压在瓶体(12)的瓶口上,并不可折卸。
