Description

STRETCH FILM DISPENSER
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to a package tool, and more particularly to a stretch film dispenser.
2. Description of the Related Art
In package task, some will wrap stretch film around the products. Usually, operator will use two dispensers, so called "hand saver", mounted on opposite ends of the stretch film roll for the package task. Conventional stretch film dispensers include a base and a reel mounted on the base for free rotation. The reel may be inserted into the core of the stretch film roll that operator may hold the base to dispense the stretch film.
Such base has a cavity at a bottom thereof, which is a hollow portion of an axle for the reel. Operator inserts his/her fingers, except thumb, into the cavity to hold the dispenser. In Europe, the most common diameters of the cores of the stretch film roll are 1.5 inches and 2 inches. When aforesaid dispenser is made for such stretch film roll, the diameter of the cavity of the base may be is 1.5 inches or less that only allows one or two fingers inserted into the cavity. In other words, operator is unable to hold the conventional dispenser firmly when the dispenser is applied for 1.5 or 2 inches stretch film roll.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a stretch film dispenser, which may be held firmly no matter what scale it is.
According to the objectives of the present invention, a stretch film dispenser includes a ball-like holding member and a reel for free rotation relative to the holding member. An operator may grasp the holding member with a palm to operate the stretch film dispenser that the holding mode of the present invention will not be affected by the size of the reel.

DETAILED DESCRIPTION OF THE INVENTION
As shown in FIGS. 1, a stretch film dispenser of the embodiment of the present invention mainly includes a base 10. a reel device 20, a brake device 40, and a second reel 52.
The base 10 has a semi-spherical shell 12 and an annular wall 14 at an open end of the shell 12 to form an annular cavity 16 between the shell 12 and the wall 14.
The annular wall 14 has a plurality of gaps 141 to form flexible plates 142 therebetween. Each flexible plate 142 has a hook 143 at an inner side thereof. The shell 12 further has four support plates 18 within the annular wall 14.
The reel device 20 has a rim 22 at a middle thereof and a reel 24 and a connecting member 26 at opposite sides of the rim 22. The rim 22 has a plurality of bores 28. The reel 24 has a plurality of ribs 30 and two indentations 32. Each indentation 32 has one of the bore 28 thereunder. The connecting member 26 has a friction portion 34 on an outer surface, and on opposite sides of the friction portion 34, there are two annular slots 36, 38. As shown in FIG 5, the connecting member 26 of the reel device 26 is inserted into the base 12 between the annular wall 14 and the support plates 18 with the hooks 143 of the flexible plates 142 engaged with the slot 38 of the connecting member 26 that the reel device 20 may be cQnnected the base 10 and may rotate freely.
The brake device 40 is a tubular member made of rubber or other soft plastics with high friction coefficient. On an outer side of the brake device 40 has grains, and on an inner side has a teeth-like texture 42 and two protrusions 44, 46 at opposite sides of the texture 42. On a bottom of the brake device 40 is a tapering bonding portion 48. The brake device 40 is fitted to the connecting member 26 with the bonding portion 48 inserted into the cavity 16 of the base and with the protrusions 44, 46 engaged with the slots 16, 28 of the reel device 20. The slot 38 is wider enough to receive both of the protrusion 46 of the brake device 40 and the hook 143 of the base 10. The texture 42 of the brake device 40 faces the friction portion 34 of the reel device 20. An outer diameter of the annular wall 14 is greater than an inner diameter of the brake device 40 that the brake device 40 is bonded to the base 10 and can not rotate with the reel device 20. As a result, the stretch film dispenser of the present invention has a ball-like (or door-knob-like) holding member 50, which consists of the base 10 and the reel 24, which may rotate freely.
The second reel 52 is a cup-like member, which is greater than the reel 24 to be put on the reel 24. The second reel 52 has a plurality of hooks 54 corresponding to the bores 28 on the rim 22 of the reel device 20 and two suspended arms 56 having a hook 54 at a distal end thereof also. The second reel 52 may be fitted to the reel 24 with the hooks 54 engaged with the bores 28 of the rim 22. To take off the second reel 52, it only has to press the suspended arms 56 to disengage the hooks 54 on the suspended arms 56 with the bores 24 and exert to pull the second reel 52 out. When the stretch film dispenser of the present invention is mounted with the second reel 52, as shown in FIG 2, the dispenser may dispense 2 inches stretch film roll; and when the second reel 52 is taken off with the reel 24 exposed, the dispenser may dispense 1.5 inches stretch film roll.
To operate the stretch film dispenser of the present invention, as shown in FIG 7, one may insert the reel 24 or the second reel 52 into a core of a stretch film roll 60 and hold the holding member 10 with the palm holding the base 10 and with the fingers grasping the brake device 40 to dispense the stretch film for package task.
When have to make a turn in the package task, operator may exert his/her fingers to press the brake device 40 that the teeth-like texture will press the friction portion 34 of the reel device 20 to stop the reel 24. As a result, with the brake of the reel 24, the operator may pull to make the stretch film having greater tension to wrap the product tightly.
Another character of the present invention is that the friction portion 34 is not a real circle. As shown in FIG 6, the friction portion 34 has a long axis A and a short axis B, and the long axis A is only 1 iiim longer than the short axis B. In other words, the friction portion 34 has two protrusion portions 58 at opposite ends of the long axis A. The brake device 40 will press the protrusion portions 58 inherently to provides the reel 24 a resistance when it is rotating. As a result, the stretch film will be pulled out with a predetermined tension to tightly wrap products. Another advantage of the protrusion portions 58 is that they help in braking the reel device 20. Beside that, operator may use all fingers to press the brake device that may reduce fatigue in operation.
It will be appreciated that a wide range of modifications and alterations may be made to the embodiment of the invention described hereinbefore without departing from the scope of the invention as defined by the appended claims.
