  • Ejector system for dispensing machines
    Patent number: 11145153
    Abstract: A product storage column for a dispensing machine includes a first member having a substantially U-shaped cross-section. The first member includes a first side wall opposing a second side wall, and both side walls extend from a back wall toward a front plane opposite the back wall. The side walls, the back wall, and the front plane cooperate to define a product space therewithin. The product storage column also includes a second member rotatably coupled to the first side wall and selectively positionable relative to the first member between an opened position and a closed position. The first member is sized to receive a product through the front plane into the product space when the second member is in the opened position, and the second member is sized to prevent movement of the product through the front plane when the second member is in the closed position.
