The invention provides a gravity automatic opening and closing cap, including a bottle cap body, a bottle cap at the bottom part of the cap body, a bottle mouth in the upper end, a cavity in the bottle stopper, a bottle neck between the upper end of the cavity and the bottle mouth, and a baffle inside the bottle neck, and a sliding rod sliding in the baffle plate. The slide rod is arranged and the upper and lower ends are respectively set up. There is an end cover and a push plate. The lower end of the bottle stopper has a liquid outlet channel, and the outlet channel is connected with the cavity. The connecting position of the outlet channel and the cavity is provided with a rolling plug seal. The invention overcomes the shortage of the existing technology, the design is reasonable, the structure is compact, the bottle cap is opened conveniently, the bottle cap is opened automatically when the bottle is tilted, the bottle cap is turned off the bottle mouth by its own gravity, and the middle ball opens out the outlet channel and top open the bottle cap when it is tilted, and falls into the outlet channel mouth below. At the same time, the round beads and the bottle cap are closed at the same time, so that the moisture and smell of the liquid in the bottle do not evaporate.
【技术实现步骤摘要】
一种重力自动开、闭瓶盖
本专利技术涉及瓶盖
,具体涉及一种重力自动开、闭瓶盖。
技术介绍
目前,市场上存在的液体瓶的瓶盖多为只有单一外盖,瓶盖要双手操作,开启不便,容易断,瓶盖一旦打开就不能再很好的利用密封了,如果瓶内液体没有用完,瓶盖不能密封,容易让瓶内液体的水分和气味挥发,不利于瓶内液体保存。
技术实现思路
(一)解决的技术问题针对现有技术的不足,本专利技术提供了一种重力自动开、闭瓶盖,克服了现有技术的不足,设计合理,结构紧凑,瓶盖开启方便,单手持瓶,倾斜瓶子时瓶盖自动打开,竖起瓶子瓶盖靠自身重力下降关闭瓶口,中间圆珠在倾斜时开启出液通道并顶开瓶盖,竖起时落入下面的出液通道口上,使瓶中液体的水分和气味不至挥发。(二)技术方案为实现以上目的,本专利技术通过以下技术方案予以实现:一种重力自动开、闭瓶盖,包括瓶盖本体,所述瓶盖本体下端部为瓶塞部,上端部为瓶口,所述瓶塞部内具有腔体,腔体上端与瓶口之间设有瓶颈,所述瓶颈内设有挡板,挡板中滑动设有滑动杆,滑动杆上、下端分别设有端盖和推板,所述瓶塞部下端具有出液通道,出液通道与腔体连通,所述出液通道与腔体连通位置设有滚动塞密封。所述瓶盖本体下端瓶塞部具有与瓶口配合的插入槽或螺纹接口。所述滚动塞为玻璃或金属。所述滚动塞为圆珠或圆锥形。所述瓶口与端盖具有配合倾斜面。所述滚动塞与腔体下部具有配合圆弧面。所述瓶盖本体为橡胶、塑料或金属制成。(三)有益效果本专利技术实施例提供了一种重力自动开、闭瓶盖。具备以下有益效果:本专利技术瓶盖开启方便,单手持瓶,倾斜瓶子时瓶盖自动打开,竖起瓶子瓶盖靠自身重力下降关闭瓶口,中间圆珠在倾 ...
【技术保护点】
一种重力自动开、闭瓶盖,包括瓶盖本体,其特征在于:所述瓶盖本体下端部为瓶塞部,上端部为瓶口,所述瓶塞部内具有腔体,腔体上端与瓶口之间设有瓶颈,所述瓶颈内设有挡板,挡板中滑动设有滑动杆,滑动杆上、下端分别设有端盖和推板,所述瓶塞部下端具有出液通道,出液通道与腔体连通,所述出液通道与腔体连通位置设有滚动塞密封。
