A 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. |
