Abstract

PURPOSE: To appropriately deliver a film by protruding a spindle from a handle of a dispenser, providing an elastic skirt coaxially with the spindle, and providing a radial groove for receiving the protruding end of a film core, between the spindle and the elastic skirt. CONSTITUTION: A hollow core 9 wound with a stretchable plastic film 8 is charged on a spindle 3 protruded from a handle 1. The protruding end of the core 9 is inserted in a radial groove 5 provided between the spindle 3 and a skirt 4 formed in a concentric state. A cap 7 is screwed into the free end of the spindle 3, and the core 9 is rotatably supported on the spindle 3. In this state, the free end of the film 8 is attached to a packed article, and the film 8 is rewound by the relative motion between the handle 1 and the packed article to wrap the article with the film 8. At this time, the rotation of the core 9, that is, the delivery of the film 8, can be stopped by manually pressing the skirt 4 to one end 10 of the core 9.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to the manual dispensing of elongated flexible materials, and more particularly to manual devices for dispensing plastic films, particularly stretchable plastic films, and the like.

In accordance with one aspect of the invention, there is provided a hand-held dispenser for an elongate flexible material that is wound in a roll around a hollow core and is rotatable with the core, the core having at least one end protruding from the roll. a spindle projecting from the handle so that the core can be rotatably mounted in use; and an elastic skirt defining the spindle and the handle, the groove receiving the projecting end of the core in use; A dispenser is provided comprising a skirt which is manually moved relative to the core to provide braking means for the core, in particular outer radial braking means.

For ease of manufacture, it is desirable to form the spindle integrally with the skirt. Similarly, it is desirable to form the no. y dollar integrally with the skirt.

Preferably, the handle, spindle and skirt are formed in one piece.

According to a preferred embodiment of the invention, there is provided a dispenser as described above further comprising removable latching means at the opposite free end of the spindle to prevent the core from disengaging from the dispenser.

The invention also relates to one example, a plastic film.

There is also provided a dispenser as described above comprising a roll of flexible material, in particular a stretchable plastic film, preferably polypropylene.

According to another aspect of the invention, a handle; a spindle attachable to the handle; and miso with the spindle;
A hand-held dispenser is provided, optionally as a kit of parts, consisting of an elastic skirt, preferably defining a radial groove and manually deformable relative to the spindle.

The present invention will be explained by way of examples with reference to the accompanying drawings.

In the figure, the dispenser 20 is a filled BPVC
It consists of a handle 1 made of aluminum and including an axially extending lip 2 to facilitate gripping.

The handle is integrally formed with both a coaxial spindle 3 and a coaxial skirt 4, the spindle and skirt together defining a radial groove 5.

The opposite end of the spindle is externally threaded to receive a screw thread cap 7.

When in use, the dispenser 20 without the cap 7 is
A sized roll 8 of stretchable plastic film is provided rotatably wound around a hollow core 9. One end 10 of the core projects from the roll and is provided with a radial groove 5.
accepted within.

The cap 7 is then screwed into place. film 8
The free end of the roll is then attached to the article to be wrapped (not shown), and relative movement between the roll and the article unwinds the roll to wrap the article in film. Wrapping speed and film tension are varied by manually moving the skirt relative to the core to provide a braking effect. When the supply film is depleted, unscrew the cap, discard the used core, and insert and latch a new core.
