Abstract

Abstract The invention is directed to a dispensing cabinet having an article chute from which cans or the like, containing a substance rendered more usable if warm, are stacked for gravity feed to a dispensing mouth and wherein one wall of the chute comprises a heat sink and is combined with one wall of the dispenser cabinet to form a chimney. The heating unit is a conventional light bulb located adjacent the dispensing mouth and beneath the heat sink whereby cans are progressively heated to a desired dispensing temperature during movement down the chute to the dispensing mouth; the light bulb also serving as an illumination source for transparent indicia incorporated in the dispenser walls.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 305 words
A dispenser for cylindrical containers of products to be heated and dispensed while heated comprising a vertical stacking chute for containing a vertically disposed stack of such containers, said chute being of substantially rectangular transverse cross section and comprising parallel front and rear walls spaced apart a distance greater than the diameter of the individual containers being dispensed by parallel side walls spaced apart a distance slightly greater than the overall height of the individual containers being dispensed, said front wall being cut away at the bottom portion thereof to form an opening in the chute for permitting discharge of the containers adjacent the bottom of said chute, said rear wall of the chute opposite said opening to form a forwardly inclined ramp for guiding said containers into said opening; a closure for the bottom of said chute, said closure including a struck-up portion extending across the bottom of the opening in said front wall of said chute and defining a stop to prevent discharge of said containers by gravity from said opening; an outer wall joined to said bottom closure and extending upwardly therefrom and completely surrounding said chute but spaced outwardly from the walls defining said chute to define therewith and therebetween a chimney, said outer wall having an opening in the bottom portion thereof registering with the opening in the front wall of said chute to permit removal of the lowermost container in said chute through said registering openings; and a heat source disposed near the bottom of said chute and beneath said forwardly inclined ramp whereby said inclined ramp, the walls defining said chute define a heat sink within said outer surrounding wall for transferring heat from said source of heat to said containers, said chimney conveying heated air upwardly toward and for discharge through the open top of said chute.
Claim 2
Dependent Claim 305 words
A dispenser for cylindrical containers of products to be heated and dispensed while heated comprising a vertical stacking chute for containing a vertically disposed stack of such containers, said chute being of substantially rectangular transverse cross section and comprising parallel front and rear walls spaced apart a distance greater than the diameter of the individual containers being dispensed by parallel side walls spaced apart a distance slightly greater than the overall height of the individual containers being dispensed, said front wall being cut away at the bottom portion thereof to form an opening in the chute for permitting discharge of the containers adjacent the bottom of said chute, said rear wall of the chute opposite said opening to form a forwardly inclined ramp for guiding said containers into said opening; a closure for the bottom of said chute, said closure including a struck-up portion extending across the bottom of the opening in said front wall of said chute and defining a stop to prevent discharge of said containers by gravity from said opening; an outer wall joined to said bottom closure and extending upwardly therefrom and completely surrounding said chute but spaced outwardly from the walls defining said chute to define therewith and therebetween a chimney, said outer wall having an opening in the bottom portion thereof registering with the opening in the front wall of said chute to permit removal of the lowermost container in said chute through said registering openings; and a heat source disposed near the bottom of said chute and beneath said forwardly inclined ramp whereby said inclined ramp, the walls defining said chute define a heat sink within said outer surrounding wall for transferring heat from said source of heat to said containers, said chimney conveying heated air upwardly toward and for discharge through the open top of said chute.
Claim 3
Dependent Claim 74 words
A dispensing device as defined in claim 1 wherein said device is an enlarged replica of the shape of the individual containers being dispensed, and wherein said outer wall is provided with transparent areas containing enlarged replicas of the advertising Material made on said containers, and wherein said heat source also serves simultaneously as a light source to illuminate said transparent areas to render said replicas of the advertising material applied thereon more visible.
Claim 4
Dependent Claim 92 words
A dispensing device as defined in claim 1 wherein said dispensing device includes a top closure having an opening therein registering with the open top of said chute, said opening being defined by at least one flanged marginal edge spaced from but adjacent said rear wall of said chute, said rear wall being terminated to define a space between itself and said top closure, whereby heated air is discharged over said wall below said closure and directed downwardly by said flanged edge prior to discharge through the opening in said top closure.
Claim 5
Dependent Claim 50 words
A dispensing device as defined in claim 1 wherein said outer wall is formed of a light-transmitting plastic having portions thereof rendered opaque and other portions remaining uncovered, said last-mentioned portions having advertising material applied thereon corresponding to the advertising material applied to the containers being dispensed by said device.
Claim 6
Dependent Claim 19 words
A dispensing device as defined in claim 1 wherein said chute is fabricated of a material having heat-conductive properties.
