Benefits of technology

[0027]It is an object of the present invention to provide a stretch wrap dispenser which has good balance and facilitates the application of film under substantially uniform tension across the full width of the film for a uniform wrap.
[0028]It is an object of the present invention to provide a stretch wrap film dispenser which can be adjusted to accommodate different widths of film rolls.

Problems solved by technology

A common problem that has occurred with prior art dispensing devices is that they do not adjust to the variations of the inside dimensions of the film core.
If the film core is too large, the roll of film will slip out of the dispenser.
Conversely, if the core is too tight, it is very difficult to push the dispenser into the core and equally as difficult to remove the dispenser when the film is used up.

Embodiment Construction

[0034]FIG. 1 shows a dispenser 10 for dispensing stretch film 12 having a handle 14. The handle 14 in a preferred embodiment being molded. In a preferred embodiment, the dispenser 10 has a foam sleeve for a cushion grip which fits over the handle 14.

[0035]FIG. 2 shows the barrel or shaft 20 of the dispenser 10. The barrel or shaft 20 of the dispenser 10 is split into two pieces 21 and 23 which allows the barrel 20 to be compressed and easily inserted into the film core 16. The barrel has located internally two cams 22 and 24. In a preferred embodiment, the front end of the barrel 20 has a raised lip 26. After the barrel 20 is inserted into the film core 16, the raised lip 26 extends beyond the end of the core 16 and prevents the stretch film 12 from coming out of the dispenser 10.

[0036]FIG. 3 shows the tensioning device 30 of the dispenser 10 of the present invention. The tensioning device 30 comprises a knob 32 at the base of the tensioning device 30 and a tapered screw 34. The ten...

Abstract

A hand dispenser for stretch film. The stretch film from the hand dispenser is dispensed by using one hand from a person. The film is wound around one end of the extended core. The dispenser comprises a handle; a split barrel or shaft and a tensioning device inserted in the barrel for creating tension against a core of stretch film.

Description

FIELD OF THE INVENTION[0001]The present invention relates to an ergonomically designed dispenser for use with stretch film.BACKGROUND OF THE INVENTION[0002]U.S. Pat. No. 4,722,493 relates to a holder for dispensing stretch film from a roll comprising a cylindrical body and an arbor rotatably supported on the body. A flexible grip having internal ribs covers the body and the arbor, so that one can by applying finger pressure to the grip brake rotation of the arbor and thus control film tension. The patent teaches that the holder comprises a handle which includes a substantially cylindrical body and a shaft extending from one end of the body. An arbor is journaled on the shaft. Means on the arbor engage the film roll, thereby constraining the roll and the arbor to rotate together on the shaft. A collar is on the arbor adjacent the handle body. One holding the handle body may create a braking torque on the roll by applying radial pressure to the collar.[0003]U.S. Pat. No. 5,203,517 rel...
