  • Patent number: 9189912
    Abstract: A lid dispenser receives a stack of drink cup lids within a housing tube, such that the frontmost lids extend through a front element opening and are retained by multiple pager assemblies, each of which has a frontwardly extending pager body post. The inside of the pager body has an engaging wall with an inclined surface directed radially inwardly. Flippers are pivoted to the posts and have wings which extend towards the front element, and have interior surfaces which are inclined radially outwardly. The flippers are biased radially inwardly, but are displaceable by a pressure applied axially towards the interior cavity. When adjusted so the pager body posts project radially over the front element opening, each pager body post inside wall is positioned to engage lids which extend from the front element opening, and direct them towards engagement with the pager flippers.

  • Patent number: 8869682
    Abstract: A food pan is configured for use with a serving station having wells within which to support the food pan. The food pan includes a bottom, a side wall, a rim, and four corner structures. The bottom has a substantially rectangular periphery. The side wall is connected to the bottom, and projects from the rectangular periphery of the bottom in an upward direction. Together, the bottom and side wall form a volume configured to support contents of the food pan. The rim is connected to the side wall on an end of the side wall opposite to the bottom, and extends from the side wall in an outward direction away from the volume formed by the side wall and the bottom. The cross-section of the rim further includes an ascending portion connected to the side wall, a top portion connected to the ascending portion, and a descending portion connected to the top portion. The ascending and descending portions are rounded.

  • Patent number: 8789723
    Abstract: A traveler has a platform which moves vertically within a carriage. By depressing one of three keys, the platform is depressed against a spring to the depth of one, two or three lids to be dispensed from a stack. With the desired key depressed, the entire carriage moves downwardly within a housing which has cams mounted to its side walls which displace spring mounted side separators which extend inwardly to separate the remainder of the stack of lids from the selected lids. The extended separators urge the selected lids past protruding pagers which support the remainder stack and prevent it from being dispensed. Once past the pagers, the selected lids are presented for one-handed removal by a user at a housing outlet. Constant force springs mounted between the carriage and the housing return the carriage to its initial position once pressure on the selected key is released.
