Abstract: A delivery track construction for use with display coolers, and dispensing devices for relatively perishable packaged products. The construction includes at least one pair of parallel inclined tracks having first and second terminal ends for gravity feeding of packages from the first to the second end. The packages are supported by a track-engaging member which slidably engages the rails. In one embodiment, the track-engaging member is in the form of a T-shaped hook defining a pair of recesses which engage the rails. In another form, the track-engaging member is in the form of a sphere of diameter sufficient to span the interstice formed by the rails. In another embodiment, the track is formed by a inclined lower wall and a pair of parallel vertical walls adapted to support cylindrical containers in parallel vertical orientation for serial dispensing.

Abstract: An improved delivery track construction for use with known coolers and dispensing devices for bottled beverages. The construction includes a series of inclined tracks having first and second adjacent terminal ends, the tracks having a one-hundred eighty degree loop between the ends. The track permits the introduction of replacement stock at an upper end for feeding under gravity to a lower end, and assures that bottles are dispensed on a first in, first out basis.

Abstract: The tamper-proof samples clamp of the invention includes a holder section that is foldable into a pair of substantially parallel spaced clamp elements having apertures which, when the clamp elements are in their parallel relationship, are in alignment. At least one pin element projects from one of the clamp elements and possesses sufficient stiffness such that it can penetrate the material of samples positioned between the clamp elements. Self-locking fasteners are provided that are dimensioned and configured for insertion through each set of aligned apertures for drawing and locking the clamp elements in clamping engagement with the samples therebetween. A hanger structure is connectable with the holder section for rotatably supporting same and the samples clamped between the clamp elements.
