Abstract

Abstract A roll film dispenser having a base unit provided with a storage roll trough and an upwardly and forwardly located dispensing trough supports additional units to form a vertical array of staggered dispensing and storage troughs for rolls of perforated sheet film. Each unit is formed from a single piece of sheet material with angularly related converging portions forming the troughs. The forward walls of the dispensing troughs are at a sufficient angle with the vertical to eliminate the need for a core weight.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 188 words
A roll film dispenser comprising a vertical array of dispensing units, each of said units being formed from a single piece of material having a first wall portion extending angularly upwardly and forwardly, a second wall portion extending upwardly and rearwardly from said first wall portion and forming a trough with said first wall portion for supporting a roll of film, a third wall portion extending rearwardly and generally horizontally from said second wall portion, a fourth wall portion extending downwardly and generally at right angles with said third wall portion, A fifth wall portion extending forwardly at generally right angles with said fourth wall portion and parallel to said third wall portion, a sixth wall portion extending forwardly and downwardly from said fifth wall portion and parallel to said second wall portion, a seventh wall portion extending upwardly from said sixth wall portion to adjacent said second wall portion, said seventh wall portion and said sixth wall portion forming a trough for storing a roll of film, and an eighth wall portion extending forwardly from said seventh wall portion and generally parallel to said second wall portion.
Claim 2
Dependent Claim 188 words
A roll film dispenser comprising a vertical array of dispensing units, each of said units being formed from a single piece of material having a first wall portion extending angularly upwardly and forwardly, a second wall portion extending upwardly and rearwardly from said first wall portion and forming a trough with said first wall portion for supporting a roll of film, a third wall portion extending rearwardly and generally horizontally from said second wall portion, a fourth wall portion extending downwardly and generally at right angles with said third wall portion, A fifth wall portion extending forwardly at generally right angles with said fourth wall portion and parallel to said third wall portion, a sixth wall portion extending forwardly and downwardly from said fifth wall portion and parallel to said second wall portion, a seventh wall portion extending upwardly from said sixth wall portion to adjacent said second wall portion, said seventh wall portion and said sixth wall portion forming a trough for storing a roll of film, and an eighth wall portion extending forwardly from said seventh wall portion and generally parallel to said second wall portion.
Claim 3
Dependent Claim 20 words
Dispensing apparatus in accordance with claim 1, wherein said second and eighth wall portions of said units are secured together.
Claim 4
Dependent Claim 29 words
Dispensing apparatus in accordance with claim 1 including means fastening said fifth wall portion of one of said units to the third wall portion of an adjacent lower unit.
Claim 5
Dependent Claim 29 words
A dispensing apparatus in accordance with claim 1 including means connected to and extending from the fifth wall portion of the lower unit supporting the dispenser on a surface.
Claim 6
Dependent Claim 49 words
Dispensing apparatus in accordance with claim 1 including a supporting leg having an upper leg portion, a forwardly extending foot, means connecting said upper leg portion to said eighth wall portion of the lowermost of said units, and means extending from said foot supporting said leg on a surface.
Claim 7
Dependent Claim 158 words
A roll film dispenser comprising a base unit having converging wall portions defining a dispensing trough and converging wall portions defining a storage trough spaced rearwardly and below said dispensing trough, said storage trough converging wall portions including a forward wall portion connected to one of said converging wall portions of said dispensing trough to support said dispensing trough, a vertical rear wall and parallel upper and lower generally horizontal wall portions extending forwardly from said rear wall and connected to said wall portions forming said troughs and an add-on unit having a horizontal wall portion and a converging storage trough portion extending from the horizontal wall portion at an angle equal to the angle defined between said base unit upper horizontal wall portion and the adjoining dispensing trough wall portion so that said add-on unit is supported by said upper horizontal wall portion of said base unit, and means connecting said add-on unit to said base unit.
Claim 8
Dependent Claim 158 words
A roll film dispenser comprising a base unit having converging wall portions defining a dispensing trough and converging wall portions defining a storage trough spaced rearwardly and below said dispensing trough, said storage trough converging wall portions including a forward wall portion connected to one of said converging wall portions of said dispensing trough to support said dispensing trough, a vertical rear wall and parallel upper and lower generally horizontal wall portions extending forwardly from said rear wall and connected to said wall portions forming said troughs and an add-on unit having a horizontal wall portion and a converging storage trough portion extending from the horizontal wall portion at an angle equal to the angle defined between said base unit upper horizontal wall portion and the adjoining dispensing trough wall portion so that said add-on unit is supported by said upper horizontal wall portion of said base unit, and means connecting said add-on unit to said base unit.
Claim 9
Dependent Claim 29 words
