Abstract:
1. An expandable gravity-feed bin, comprising: a generally hollow main bin including: a first, generally hollow, extension section having second and third edged perimeters, the first extension section being selectably coupled to the open end of the main bin, the first edged perimeter having opposing first interior and first exterior surfaces, the second edged perimeter having opposing second interior and second exterior surfaces, and the third edged perimeter having opposing third interior and third exterior surfaces, the first extension section being in communication with the reservoir; and a resilient seal element disposed intermediate to the main bin and the first extension section, the seal element including a first receptacle, a second, opposing receptacle, and an interior and an exterior face, the first receptacle being configured to sealingly engage the first interior and the first exterior surfaces of the first edged perimeter and the second receptacle being configured to sealingly engage the second interior and the second exterior surfaces of the second edged perimeter, thereby providing a substantially air-tight seal between the main bin and the first extension section upon engagement, an upper portion of the interior face of the seal element being substantially in the same plane with an interior side of the first extension section, when assembled, the storage capacity of the gravity-feed bin being increased by the coupling of the first extension section to the main bin.
