Abstract
Abstract A display device includes a hollow base having a slot in its top wall and a bottle simulating transparent shell has its rear opening covered by a plurality of superimposed transparent sheets having relatively vertically staggered, translucent faced dimples formed in their rear faces, their lower border interfaces opaque with these lower borders engaging the slot and the remaining borders opaque. A longitudinally slotted hollow cylinder is motor rotated in the base and a lamp is located in the cylinder so that the bottom edges of the sheets are cyclically successively illuminated whereby the light dispersing dimples provide the illusion of rising bubbles in the bottle.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
122 words
A display device comprising a plurality of superimposed transparent sheets each having formed in the rear face thereof a plurality of vertically and transversely spaced individual concave dimples which are vertically staggered relative to corresponding dimples in the other sheets, a three-dimensional contoured transparent body member simulating a liquid receptacle disposed forwardly of and adjacent to said sheets and including a hollow shell having a convex front face and a concave rear face, the border of the forwardmost sheet overlying the perimeter of said shell and illuminating means for cyclically sequentially illuminating corresponding adjacent edges of said sheets whereby to cyclically sequentially illuminate the dimples in successive sheets and provide an illusion of rising bubbles in said liquid receptacle simulating body member.
Claim 2
Dependent Claim
122 words
A display device comprising a plurality of superimposed transparent sheets each having formed in the rear face thereof a plurality of vertically and transversely spaced individual concave dimples which are vertically staggered relative to corresponding dimples in the other sheets, a three-dimensional contoured transparent body member simulating a liquid receptacle disposed forwardly of and adjacent to said sheets and including a hollow shell having a convex front face and a concave rear face, the border of the forwardmost sheet overlying the perimeter of said shell and illuminating means for cyclically sequentially illuminating corresponding adjacent edges of said sheets whereby to cyclically sequentially illuminate the dimples in successive sheets and provide an illusion of rising bubbles in said liquid receptacle simulating body member.
Claim 3
Dependent Claim
16 words
The display device of claim 1 wherein the concave faces of said dimples are relatively opaque.
Claim 4
Dependent Claim
22 words
The display device of claim 2 including opaque partitions interposed between confronting borders of said sheets proximate the illuminated end edges thereof.
Claim 5
Dependent Claim
33 words
The display device of claim 1 wherein said illumination means includes a source of illumination and means for cyclically sequentially exposing successive adjacent corresponding edges of said sheets to said source of illumination.
Claim 6
Dependent Claim
51 words
The display device of claim 4 including a hollow base member having a top wall with a slot therein, the bottom border of said body members and sheets and said partition projecting through said slot said source of illumination and said sequential exposing means being housed in said hollow base member.
Claim 7
Dependent Claim
55 words
The display device of claim 5 wherein said sequential exposing means includes a hollow cylinder disposed directly below and extending along the lengths of said sheet end edges and having circumferentially spaced longitudinal slots formed therein and a motor rotating said cylinder about its axis and said source of illumination is disposed within said cylinder.
Claim 8
Dependent Claim
26 words
The display device of claim 6 wherein the widths of said slots are each equal to between the width of one and two of said sheets.
Claim 9
Dependent Claim
25 words
The display device of claim 4 wherein said exposure means always exposes at least one of said sheet end edges to said source of illumination.
