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.

8 Claims, 3 Drawing Figures 1 ROLL FILM DISPENSER BACKGROUND OF INVENTION The invention relates to dispensers and more particularly to roll film dispensers for dispensing rolls of web material having perforations at equally spaced intervals.

SUMMARY OF INVENTION The invention provides a roll film dispenser for storing and dispensing multiple rolls of web material with a base unit formed from a single piece of sheet material to provide a storage trough and a forwardly and upwardly located dispensing trough. Additional units can be added on as required to form a vertical array of staggered storage and dispensing troughs. The staggered relationship of the troughs minimizes the overall height of the dispenser and lowers the center of gravity to provide a compact dispenser capable of storing a number of rolls of various types of film. Each unit has complementary, parallel, horizontal wall portions which permit the units to be stacked. Fasteners extending through the wall portions secure the adjacent units together.

The base unit is provided witha detachable forwardly extending leg with .a horizontal foot which is provided with suction cups. Suction cups are also secured to the horizontal wall portion of the base unit. The forward wall portion of the storage trough of each unit extends upwardly and connects to the rearward wall portion of the dispensing trough to support the dispensing trough and rigidify the forward wall of the storage trough. The forward wall portions of the dispensing troughs are at an angle of 20 to 25 with the vertical to eliminate the need for a core weight.

It is an object of the invention to provide a film dispenser in which units formed from a single piece of material and having a storage trough and dispensing trough can be added as required to a base unit to form a rigid vertical. stack.

' It is an additional object of theinvention to provide ally designated and which includes three vertically stacked units or tiers including a base unit 12 and

upper units

14 and 16. Each of the units can be formed from a single piece of material with a first wall portion 18 having

edges

20 and 22 which converge upwardly to form a piercing or tear edge 23. The wall portion 18 and a wall portion 26 converge downwardly to form a trough which supports a roll of film 24 in a dispensing position.

To facilitate stacking of the units, each unit is provided with a generally horizontal wall portion 28 which connects wall portion 26 to a vertical wall portion 30. The vertical wall portion 30 is connected with a forwardly extending generally horizontal wall portion 32 which is parallel with wall portion 28 and is connected with a downwardly inclined wall portion 34 which is parallel with wall portion 26. As shown in FIG. 3, the

wall portions

32 and 34 are respectively supported on

wall portions

28 and 26 of the lower unit when the units are stacked.

To support the dispensing trough 25 and provide a storage trough for an extra roll, a wall portion 36 extends angularly upwardly from wall portion 34 and is a compact film dispenser for storing multiple rolls of film comprising a vertical array of units with staggered storage troughs and dispensing troughs with the forwardly and upwardly inclined wall portions of the storage troughs supporting the dispensing troughs and in which horizontal parallel wall portions form abutting supporting surfaces for adjacent units.

Further objects and advantages of the inventionwill become apparent from the following disclosure.

DESCRIPTION OF DRAWINGS FIG. 1 is a perspective view of a film dispenser in ac-' cordance with the invention. I

FIG. 2 is an exploded view of two'dispenser units. FIG. 3 is an enlarged end view of a dispenser in accordance with the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT connected with a wall portion 38 which is parallel with the wall portion 26. The wall portion 36 is connected to wall portion 26 by fasteners 42 and provides rigidity for the dispensing trough 25.

The lower unit 12 isprovided with a forwardly extending leg 44 which has an upper leg portion 53 connected to a wall portion 38 by afastener 42. The leg 44 has an out-turned flange or foot-46 provided withsuction cups 48 fastened to the foot 46 by'bolts 49. The wall portion 32 of the base unit 12 is also provided with two suction cups 50 for 'anchoring'and'supporting' base unit 12 on a'surface. Inasmuch as'the

wall portions

28 and 32 and the

wall portions

26 and 34 of each of the units are parallel, they can be stackedas shown in FIG. 3 with wall portion 32 of unit 14 in engagementwith wall portion 28 of unit 12. The wall portion 34 of unit 14 is supported on the wall portion 26 of unitl2. Fasteners51 secure the adjacent units together.

The vertical row of storage-troughs 40 adjacent the rear walls 30 and the stored rolls contained herein provide weight on the suction cups 50. The vertical row of dispensing rolls adjacent the suction cups 48 provides weight on the suction cups 48 thus stabilizing the vertical stack of units and insuring that the suction cups remain in firm engagement with the supporting surface. The. staggered relationship of the storage troughs and dispensing troughs provide a compact dispenser with a low center of gravity to minimize translatory movement of the dispenserduring severance of. sheets from the rolls.

The angle A between the forward wall portions 18 and the vertical is desirably between 20 and 25, to

eliminate the need for a core weightwhich is employed with prior art dispensers to prevent the roll from climbing out of the dispensing trough during withdrawal of film.
