Abstract
Abstract The disclosure is of a stacked structure made up of a plurality of identical box-like units arranged one atop the other in a near vertical array in which each unit presents a front face angled to the vertical in such fashion that the front face of each unit forms a dihedral angle with its next lower and next upper unit. Each unit has a floor and a roof that diverge rearwardly relative to each other which causes each upward unit, resting via its floor on the roof of the next lower unit, to tilt forwardly so that its front face is at a lesser angle to the vertical than the angle between the front face of the next lower unit and the vertical. The configuration is such that the increments by which the angles decrease from bottom to top are equal. The units are basically transparent to expose the unit contents and each unit has a dispensing means in its rear part.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
209 words
A stacked display and dispensing structure comprising: a base unit of box-like configuration having a floor, a roof, front wall means extending between and fixedly joined to the floor and roof respectively at bottom front and top front corners, and rear wall means extending between and fixedly joined to the floor and roof respectively at bottom rear and top rear corners, the angle between the front wall means and the floor being less than ninety degrees so that the front wall means slopes upwardly and rearwardly from the floor and the angle between the front wall means and the roof being greater than ninety degrees so that the roof slopes upwardly and rearwardly from the front wall means in divergent relation to the floor; a second unit having a floor and front wall means joined together at a bottom front corner and angle identical to the bottom front corner and angle of the base unit, said second unit being mounted atop the base unit via the floor of the second unit and the roof of the base unit with the second unit bottom front corner directly above the top front corner of the base unit, whereby the planes of the two front wall units meet at a dihedral angle.
Claim 2
Dependent Claim
209 words
A stacked display and dispensing structure comprising: a base unit of box-like configuration having a floor, a roof, front wall means extending between and fixedly joined to the floor and roof respectively at bottom front and top front corners, and rear wall means extending between and fixedly joined to the floor and roof respectively at bottom rear and top rear corners, the angle between the front wall means and the floor being less than ninety degrees so that the front wall means slopes upwardly and rearwardly from the floor and the angle between the front wall means and the roof being greater than ninety degrees so that the roof slopes upwardly and rearwardly from the front wall means in divergent relation to the floor; a second unit having a floor and front wall means joined together at a bottom front corner and angle identical to the bottom front corner and angle of the base unit, said second unit being mounted atop the base unit via the floor of the second unit and the roof of the base unit with the second unit bottom front corner directly above the top front corner of the base unit, whereby the planes of the two front wall units meet at a dihedral angle.
Claim 3
Dependent Claim
138 words
A structure according to claim 1, in which the second unit is identical to the base unit and includes a roof joined to its front wall means at a top front corner and angle identical to those of the base unit, and a third unit having a floor and front walls means joined together and a bottom front corner identical to those of the base and second units, said third unit being mounted atop the second unit via the floor of the third unit and the roof of the second unit with the bottom front corner of the third unit directly above the top front corner of the second unit, whereby the planes of the front wall means of the second and third units meet at a dihedral angle between the base and second unit front wall means.
Claim 4
Dependent Claim
30 words
A structure according to claim 1 in which the sum of the angles at the bottom and top front corners of the base unit is in the range of 181°-184°.
Claim 5
Dependent Claim
21 words
A structure according to claim 3, in which the angle at the bottom front corner is in the range of 80°-84°.
Claim 6
Dependent Claim
13 words
A structure according to claim 4, in which said angle is about 82.75°.
Claim 7
Dependent Claim
13 words
A structure according to claim 4, in which said angle is about 81°.
Claim 8
Dependent Claim
18 words
A structure according to claim 1, in which the dihedral angle is in the range of about 179°-176°.
Claim 9
Dependent Claim
99 words
A stacked display and dispensing structure comprising: a base unit of box-like configuration having a flat floor lying in a single plane, a flat roof lying in a single plane and front and rear ends, the planes of the floor and roof diverging rearwardly from front to rear, a second identical unit stacked atop the base unit with the plane of its flat roof and flat floor also diverging rearwardly and with its floor superimposed flat-wise over the entire roof of the base unit, and means affixing the floor of the second unit to the roof of the base.
Claim 10
Dependent Claim
99 words
A stacked display and dispensing structure comprising: a base unit of box-like configuration having a flat floor lying in a single plane, a flat roof lying in a single plane and front and rear ends, the planes of the floor and roof diverging rearwardly from front to rear, a second identical unit stacked atop the base unit with the plane of its flat roof and flat floor also diverging rearwardly and with its floor superimposed flat-wise over the entire roof of the base unit, and means affixing the floor of the second unit to the roof of the base.
Claim 11
Dependent Claim
29 words
