  • Patent number: 4286733
    Abstract: A valve for controlling gravity flow of a fluent product such as milk from a flexible bag of the product through an opening in the bag formed by severing a corner off the bag. The valve includes a pair of spring loaded jaws which engage the bag on opposite sides just above the opening formed by the removal of the corner. Cooperating cam surfaces on the jaws and on movable frames cause the jaws to move toward and away from each other as the frames are moved with respect to each other. Movement of the jaws away from each other causes the edges of the bag at the opening to become taut and restrict flow through the opening, while movement of the jaws towards each other relaxes the bag material adjacent the opening to enhance flow through the opening. The frames also carry resilient sealing bars which engage opposite sides of the bag just above the opening and seal the opening when the jaws are moved away from each other.
