US Classification:

221263, 221133, 221222, 221277

Abstract:

A coupling for connection of a tube comprises a coupling housing which includes a first end into which the tube is inserted, a clamping ring which is positioned in the coupling housing against a first conical surface, a sealing ring which is positioned in the coupling housing, and a return ring which is positioned in the coupling housing between the clamping ring and a second end of the housing adjacent a second conical surface that is tapered opposite to the first conical surface. The return ring is expandable and comprises a central aperture which is smaller than the external diameter of the tube. Accordingly, when the tube is pushed into the coupling housing and forced through the return ring, the return ring will expand and move along the second conical surface.

Abstract:

A vending machine includes a cabinet having a product storage zone and a product delivery mechanism that transports a selected product to a consumer. The vending machine includes a door assembly pivotally mounted relative to the cabinet for selectively providing access to the product storage zone. The door assembly includes an outer, exposed surface and an inner surface that are spaced to define an inner door zone including a vertical drop zone that terminates in a delivery area. A portal is formed in the inner surface of the door assembly and leads from the product storage zone into the door zone. A discharge element is provided on the inner surface of the door assembly and cooperates with the product delivery mechanism to dispense the selected product through the portal as the product delivery mechanism moves past the portal.
