Abstract:
A collapsible article is disclosed herein which comprises: a plurality of slats, each slat having opposing longitudinally extending edges, a flute extending along one edge, a bead extending along the other edge and adapted to fit within the flute of an adjacent slat, and at least one opening transversely extending between the bead and flute; and at least one elongated elastic member received in and extending through said at least one opening of each slat so that the slats are selectively positionable between (i) an expanded, hollow form having opposing open ends, and (ii) a collapsed, substantially flat form. The collapsible article preferably further comprises a support member engageable with the slats in their expanded form and removable from the slats to allow collapse thereof.
Abstract:
An apparatus for storing and dispensing particulate material, such as bird seed, employs a dispensing valve having a first disk fixedly mounted in a housing and a second disk rotatably mounted in the housing. The first disk has circumferentially spaced first apertures and the second disk has circumferentially spaced second apertures. The boundaries of the first apertures intersect the periphery of the first disk, and the boundaries of the second apertures intersect the periphery of the second disk. The second disk can be rotated to select a desired position, such as a closed position in which the first and second apertures are completely unaligned, a fully open position in which the first and second apertures are completely aligned, or a partially open position in which the first and second apertures are partially aligned.
