Abstract
Abstract A carton for cutting and dispensing sheet material in flattened form with a cutter mechanism for effecting same. The cutter is part of an upper bar suitably attached to the top wall member of the carton with the top normally maintained open by a spring carried by one or both of separate plastic end cap members. The upper bar also carries a pair of parallel plate-like members which extend laterally for substantially the full length of the carton and engages and wipes past a pair of similar parallel plate-like members on a lower bar attached to the front panel. This wiping action places the sheet material, which is manually positioned to overlie the lower bar, in tension with the cutter severing the tensioned sheet material.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
291 words
An improved cutter mechanism for attachment to a parallelepiped carton to dispense sheet materials, said cutter mechanism comprising: (a) an upper bar mechanism having two substantially parallel planar surfaces disposed on opposite sides of a cutter mechanism positioned intermediate said planer surfaces, (1) said upper bar mechanism being attached to a top wall of said carton by means of a pair of walls forming a channel-shaped extension of said upper bar mechanism for insertion and attachment of said top wall of said carton, said top wall being hingedly attached to a rear wall of said carton, (2) said upper bar mechanism having a web member from which said two planer surfaces and said cutter mechanism extend in parallel planes, (3) said web member constituting an extension of one of said walls forming said channel-shaped extension of said upper bar mechanism, (b) a lower bar mechanism having two substantially parallel planer surfaces and an interconnecting web to define a channel, (1) said lower bar mechanism being attached to a front wall of said carton by means of a pair of walls forming a channel-shaped extension of said lower bar mechanism for insertion and attachment of said front wall of said carton, (c) said planer surfaces of said upper bar mechanism being so positioned and arranged that when said top wall of said carton is moved to a substantially horizontal plane, the inside surfaces of said planer surfaces of said upper bar mechanism engage the outer surfaces of said channel formed by the planer surfaces of said lower bar mechanism thereby exerting a wiping action on any sheet material which overlays said channel of said lower bar mechanism in tension and said cutter mechanism severs said sheet material while it is under tension.
Claim 2
Dependent Claim
291 words
An improved cutter mechanism for attachment to a parallelepiped carton to dispense sheet materials, said cutter mechanism comprising: (a) an upper bar mechanism having two substantially parallel planar surfaces disposed on opposite sides of a cutter mechanism positioned intermediate said planer surfaces, (1) said upper bar mechanism being attached to a top wall of said carton by means of a pair of walls forming a channel-shaped extension of said upper bar mechanism for insertion and attachment of said top wall of said carton, said top wall being hingedly attached to a rear wall of said carton, (2) said upper bar mechanism having a web member from which said two planer surfaces and said cutter mechanism extend in parallel planes, (3) said web member constituting an extension of one of said walls forming said channel-shaped extension of said upper bar mechanism, (b) a lower bar mechanism having two substantially parallel planer surfaces and an interconnecting web to define a channel, (1) said lower bar mechanism being attached to a front wall of said carton by means of a pair of walls forming a channel-shaped extension of said lower bar mechanism for insertion and attachment of said front wall of said carton, (c) said planer surfaces of said upper bar mechanism being so positioned and arranged that when said top wall of said carton is moved to a substantially horizontal plane, the inside surfaces of said planer surfaces of said upper bar mechanism engage the outer surfaces of said channel formed by the planer surfaces of said lower bar mechanism thereby exerting a wiping action on any sheet material which overlays said channel of said lower bar mechanism in tension and said cutter mechanism severs said sheet material while it is under tension.
Claim 3
Dependent Claim
45 words
An improved cutter mechanism as defined in claim 1 wherein said cutter mechanism comprises a series of V-shaped teeth with the roots of said teeth being formed with a radius to prevent the generation of fines from the sheet material cut by said cutter mechanism.
Claim 4
Dependent Claim
19 words
An improved cutter mechanism as defined in claim 2 wherein said cutter mechanism is formed from a plastic material.
Claim 5
Dependent Claim
20 words
An improved cutter mechanism as defined in claim 1 wherein said upper bar mechanism is formed from a die casting.
Claim 6
Dependent Claim
19 words
An improved cutter mechanism as defined in claim 1 wherein said lower bar mechanism is formed from an extrusion.
Claim 7
Dependent Claim
42 words
An improved cutter mechanism as defined in claim 5 wherein said two substantially parallel planar surfaces on said lower bar mechanism and said channel-shaped extension for insertion and attachment of the front wall of said carton form a substantially H-shaped cross section.
Claim 8
Dependent Claim
52 words
An improved cutter mechanism as defined in claim 6 wherein the web forming the bottom of the channel between said two substantially parallel planar surfaces of the lower bar mechanism extends rearwardly into said carton to form a shelf on which the leading end of the sheet material to be dispensed rests.
Claim 9
Dependent Claim
40 words
An improved cutter mechanism as defined in claim 7 wherein said shelf is removed adjacent each end of said carton to provide space for the finger of the user to grasp the edges of the sheet material to be dispensed.
