Description

The present invention relates to a device for dispensing plastic stretch film, and more particularly to a device for manually coating plastic stretch film around packages such as filled pallets.

There are many conventional devices for coating plastic films around packages. For example, U.S. Pat.
No. 1 discloses a plastic stretch film manual dispenser of the type in which the film is received in a core with protruding ends. In this case, a pair of flexible hand grips are rotatably mounted on both ends of the core, so that the tension of the film can be controlled by hand to grip the hand grip strongly during the dispensing to brake the core. It is done by doing. This dispenser is a good manual dispenser for stretched films but has the disadvantage that it is difficult to coat the film around the package near the ground plane of the package if both ends of the core are protruding. . Therefore, it is an object of the present invention to provide a dispensing device that can overcome this problem.

MEANS TO SOLVE THE PROBLEM this invention solves the above-mentioned subject, The hollow core which wound the roll of the plastic film, and was made rotatable with the plastic film, One end part of the hollow core which protruded from the roll of the plastic film, One of the hollow core A flexible handgrip which is rotatably attached to the end of the plastic film so that the tension of the plastic film core can be adjusted manually.
Only one end of the hollow core projects from the roll of plastic film and the other end of the hollow core is approximately U
One arm of the U-shaped handle is rotatably mounted so that the one arm is elastically deformable with respect to the inner surface of the hollow core; The arm is characterized by providing a plastic stretch film manual dispenser, wherein the arm is spaced from the axis of the hollow core but extends substantially parallel to the axis toward one end of the hollow core. is there.

Turning to the embodiments of the present invention with reference to the drawings, the device comprises a hollow core 11 on which a roll of plastic stretch film 12 is wrapped. The length of the core 11 is one end of the core 11.
It is longer than the width of film 12 so that 13 projects from the adjacent edges of the rolled stretch film. However, the other end 14 of the core is made to be the same as the edge adjacent to the film.

A cup-shaped PVC is appropriately attached to one protruding end 13 of the core 11.
A flexible handgrip 15 which is a member is rotatably attached. If desired, an axially extending ridge (not shown) may be provided on the outer surface of the handgrip 15 to further facilitate gripping.

At the other end 14 of the core 11 is a generally U-shaped handle molded of polyethylene or other suitable thermoplastic material.
17 arms 16 are attached. Handle 16 arm 16
Has a generally hollow cylindrical shape, and at least its free end has an outer diameter slightly larger than the inner diameter of the core. However, the arm 16 is formed with a slot 18 extending in the axial direction, and the arm 16 is elastically deformed so as to close the slot 18 so that the arm 16 can move to the core 11.
It is adapted to be inserted into the other end 14 of the. Therefore, when the film is manually unwound, the arm 16 is pressed against the inner surface of the core 11 by its own elasticity, the handle 17 is releasably held by the core 11, and at the same time the core is free to move with respect to the handle. Can rotate.

The other arm 19 which is a part of the handle 17 is also hollow-cylindrical in shape, and its axis is substantially parallel to this axis even if it is away from the core 11, and has a shape extending toward the end 13 of the core. I am doing it. The arm 19 is preferably formed with an axially extending ridge on the outside for facilitating gripping of the handle 17, and the arm 19 is formed by a shallow trough-shaped base member 21 reinforced by an inner rib 22. It is connected to 16. By making the arms 16 and 19 hollow and making the base member 21 a trough shape, the amount of material required to mold the handle 17 is very small. In this way, since the cost of the handle 17 is reduced, the roll-shaped film 12 may be used up, and then the entire dispensing device including the handle 17, the core 11 and the handgrip 15 may be treated as a disposable type.

The dispensing device according to the invention is film-wrapped around a package such as a filled pallet, i.e. a film.
When the 12 is used to coat the pallet, the arm 19 of the handle 17 of the dispenser is grasped by the hand grip 15 with both hands, while the core 11 is rotatable on the arm 16 paired with the arm 19. Since the unwinding of the film 12 can be adjusted by firmly gripping the hand grip 15, it is possible to achieve the optimum winding by adjusting the gripping method of the grip 15 so that the film is wound on the pallet in a tensioned state. it can.

Furthermore, when the film roll is erected during use, the film 12 extends almost completely to the other end 14 of the core 11, and the distance between the film edge and the ground surface is only about the thickness of the thin base member 21. As a result, the film roll can be wound on a pallet or the like while being unwound on a package up to near the ground surface. If the film enters a pallet or the like in a direction in which the film is skewed to the vicinity of the ground, the film will be twisted or unwound, which will be eliminated. That is, in the dispensing device of the present invention, one end of the core is virtually absent unlike the conventional device, and therefore, when the film roll is set up, the lower edge of the film roll is brought close to the surface until work is completed. As a result, the film can be smoothly unwound, and it is easy to wind the film on the entire surface of the pallet on the ground, which has a unique effect that efficient work can be realized.
