Abstract
Abstract An apparatus for stretching a plastic film around a package is disclosed wherein two handles are secured to the core of the plastic film, one handle effectively extending the core and having a braking cover for dispensing speed control. The other handle includes a U-shaped member to provide a second grip parallel to, but displaced from the axial centerline of the core. The plastic film is configured between the two handles for rotation about the centerline axis of its core.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
126 words
An apparatus for dispensing plastic film having a hollow core with an axial centerline comprising: a first handle extending along the axial centerline of the core and fixed to the core for simultaneous rotation therewith; a flexible handgrip covering said first handle configured for slideable rotation on said first handle; and a second generally U-shaped handle with two members, a first resilient member having a centerline coincident with said centerline of said core and a second member having a centerline parallel to said centerline of said core, said first member mounted in said core to remain stationary and urging by its own resiliency against the internal surface of said core, while permitting axial rotation of said core and said second member arranged to provide a handgrip.
Claim 2
Independent Claim
126 words
An apparatus for dispensing plastic film having a hollow core with an axial centerline comprising: a first handle extending along the axial centerline of the core and fixed to the core for simultaneous rotation therewith; a flexible handgrip covering said first handle configured for slideable rotation on said first handle; and a second generally U-shaped handle with two members, a first resilient member having a centerline coincident with said centerline of said core and a second member having a centerline parallel to said centerline of said core, said first member mounted in said core to remain stationary and urging by its own resiliency against the internal surface of said core, while permitting axial rotation of said core and said second member arranged to provide a handgrip.
Claim 3
Dependent Claim
118 words
A plastic film dispenser comprising two handles for use with a plastic film roll having a hollow core with an axial centerline, a first handle fixed to said core for rotation therewith and having a slideably mounted handrip, a second handle mounted in said core for permitting rotation of said core while said second handle remains stationary, said second handle being U-shaped with three members, one resilient member mounted in said core and urging by its own resiliency against the internal surface of said core, a second member parallel to said core and a third member connecting said one member and said second member, said third member mounted perpendicular to said core and extending slightly beyond said core.
Claim 4
Dependent Claim
118 words
A plastic film dispenser comprising two handles for use with a plastic film roll having a hollow core with an axial centerline, a first handle fixed to said core for rotation therewith and having a slideably mounted handrip, a second handle mounted in said core for permitting rotation of said core while said second handle remains stationary, said second handle being U-shaped with three members, one resilient member mounted in said core and urging by its own resiliency against the internal surface of said core, a second member parallel to said core and a third member connecting said one member and said second member, said third member mounted perpendicular to said core and extending slightly beyond said core.
