Abstract

一种弯管水封式保温瓶塞。可用陶瓷或塑料外 套胶圈制成,在瓶塞中心留有一大一小两条蛇形弯曲 管道连通瓶内外,其弯曲处可存水密封,倾斜水瓶即 可将水倒出。制作简单,使用方便,保温效果好。

Description

本实用新型涉及一种保温水瓶塞。
现有的水瓶塞多为软木制成,倒水时需取下瓶塞,倒后再盖上,开启频繁,不够方便,也影响保温效果。目前已有人提出了在瓶塞中装玻璃球或偏心舌来改进。使之能直接倒水。但采用上述办法制作较为复杂,保温效果不够理想。
本实用新型的目的在于提供一种倒水方便,制作简单,保温效果较好的新型保温瓶塞。
本实用新型可用陶瓷或塑料制造,瓶塞中心留出一大一小两条蛇形弯曲管道连通瓶内外。大管道为出水管,小管道为进气管,在小管道中部留有一停水窝。水瓶直立时,两弯管内的存水将内外隔开,由于靠瓶内的一段存水上热下冷,不能产生对流,故能较好保温。倒水时直接将水瓶倾斜,热水自大管道流出,进气管中的存水流自停水窝,空气能顺利进入瓶内充填,瓶中压力过大时,多余的空气又从进气管经停水窝排出,不会冲掉水封。瓶塞外面套有一密封胶圈,使瓶口与瓶塞能紧密吻合。
与现有技术相比较,本实用新型具有倒水方便,制作简单,保温效果好的优点。
本实用新型的附图说明如下:(图1为弯管水封瓶塞的内部构造剖面示意图)
1、出水弯管        2、进气弯管
3、停水窝        4、密封胶圈
下面结合附图对本实用新型作进一步描述。
如图所示,出水管1的进水口与进气弯管2的进气口各在瓶塞的一边,停水窝3在进气管中部,密封胶圈4套在瓶塞外面。
