用于控制液体倾倒，防止泄漏。
专利摘要
一种用于液体容器的倾倒装置，其配合到容器开口的颈部中。该倾倒装置具有浮力中空球阀，当容器或瓶子处于其正常垂直存储位置时，该球阀由坐在倾倒装置远端内唇上的弹簧压靠倾倒装置的内唇以形成密封。当容器倒置时，阀门打开，因为中空球阀的浮力如此之大以至于它克服弹簧偏压，从而允许容器的流体内容物倒出。中空球阀的运动由沿倾倒装置长度的至少一个垂直突出部控制。
Original abstractA pouring device for a liquid filled container that fits into the neck of a container opening. The pouring device has a buoyant hollow ball valve that when the container or bottle is seated in its normal vertical storage position is pressed against an inner lip of the pouring device to form a seal by a spring that is seated on a distal inner lip of the pouring device. The valve opens when the container is inverted as the hollow ball valve is so buoyant that it overcomes the spring bias, thereby allowing the container's fluid contents to pour out. The hollow ball valve's movement is controlled by at least one vertical projection along the length of the pouring device.
