Description

HAND-HELD DISPENSER FOR WRAPPING MATERIALField of the Invention

[0001] This invention relates to a hand-held dispenser for wrapping material for use in wrapping bulk products for transport purposes.Background to the Invention

[0002] It is usual to wrap pallet loads of products, for example, using flexible and stretchable plastics film to hold the products, typically in individual cartons, together during shipping. This wrapping operation is often carried out manually, using a roll of the plastics film carried on a hand-held dispenser. Known handheld dispensers, for example as disclosed in EP3100960A1 , EP2135807A1 , US2021 / 0171232A1 , and GB GB2115783A, comprise a vertical mount for the roll of film, carried by a handle extending generally parallel to the axis of the roll. In some examples, an additional handle extends along the axis of the roll at one end thereof. In use, the dispenser is held with the axis of the roll vertical and the film is wound on to the stack of products (boxes) on the pallet as the user moves around the stack. This manoeuvre typically involves the user pulling the carrier behind them as they walk around the stack. Most users find this uncomfortable for prolonged use. Alternatively, the user will walk backwards around the pallet whilst unwinding and stretching the material on to the load. Both methods involve the predominant use of one hand / arm whilst securing the load.

[0003] In BE1001343A3, there is disclosed a dispenser with one shaft for carrying the roll of plastics film and a separate handle alongside the shaft. The shaft needs to be detached to fit the roll, and tension is adjusted by the handgrip at the upper end of the shaft. US7900421 B1 discloses a device having a pair of shafts over which the core of the roll is located, a handle to one side being used to carry the device and being provided with means for varying the lateral spacing between the shafts to var the tension on the film as it is unwound. The disclosure of US7357349B1 is similar.

[0004] EP4046925A2 discloses a dispenser with a screw-adjustable shaft with an opposed pair of cones for receiving the ends of a roll of film, and with a hinged handle on each end of the shaft to carry the dispenser and rotate theshaft parts to adjust the tension. FR2748722A1 discloses a device having two parallel shafts, one to receive the roll of film and the other to mount a pivoted second handle that has an arm which presses on to the upper end of the roll to vary the tension on the film. Precise control of the tension is difficult to achieve.Summary of the Invention

[0005] According to the present invention, there is provided a hand-held dispenser for holding a roll of a wrapping material, the dispenser comprising a parallel pair of handles each having an arm extending from at least one end thereof connected to a mount for receiving the roll extending parallel to the handles in use, wherein an arm extends from both ends of each handle, the opposed connected ends of the arms being configured to mount the roll between them.

[0006] Other preferred features of the invention are set out in the claims.

[0007] The dispenser of the invention is suitable for use in front of the user as they walk around the stack of items to be wrapped, rather than pulled behind the user, greatly increasing the comfort and convenience of the wrapping procedure.Brief Description of the Drawings

[0008] In the drawings, which illustrate an exemplary embodiment of the invention:Figure 1 is a side elevation of the dispenser with a roll of wrapping material installed;Figure 2 is a rear elevation of the dispenser shown in Figure 1 ; andFigure 3 is an exploded view from the front of a modified form of the dispenser, without the roll installed.Detailed Description of the Illustrated Embodiment

[0009] Referring to Figures 1 and 2, the hand-held dispenser consists of a pair of handles 1 and 2 arranged parallel to each other and each having an arm 1a, 1 b, 2a, 2b extending generally normally thereto at each end. The arms at each end of the handles 1a and 2a, 1b and 2b, are respectively joined together with an angle of 90° between them and with a roll support 3a and 3b mounted on the point at which the arms join. The roll supports 3a and 3b receive the op-posed ends of the core 4 on which the roll 5 of wrapping film is held, enabling the roll to rotate as the film is wound on to the articles being wrapped.

[0010] The handles and arms 1 and 2 are configured as two telescopically adjustable units 6 and 7, which can be moved away from and towards each other to permit removal and fixing of the core 4 of the roll 5. The movement also permits variations in the length of the core 4 to be accommodated. One handle 2 is configured vary in length telescopically, with a slidable tubular sleeve or grip 18 extending over the two parts thereof. The other handle 1 is extendible by twisting a grip member 8 extending over the two parts of the handle to screw the parts towards or away from each other, as explained in more detail hereinafter with reference to Figure 3.

[0011] In use, the person carrying out the wrapping operation grasps the two handles to hold the roll 5 in the upright or generally vertical position and walks around the stack of objects to be wrapped with the dispenser in front of them and the film unwinding to the side of the person on to the stack. This makes the wrapping operation easier to control and more comfortable for the user.

[0012] Referring now to Figure 3, the two telescopically adjustable units 6 and 7 are each formed from a single piece of metal tubing bent to form the two arms 1a, 2a, 1 b, 2b with a curved section 8, 9 between them on which is welded a support base 10, 11 in the form of a disc having a screw-threaded aperture 12, 13 at the centre. A recessed disc 14, 15 is rotatably mounted on the support base 10, 11 by means of a screw-threaded spindle 16, 17 screwed into the screw-threaded aperture 12, 13. The lower unit 6 has an extension tube 23 secured in the end of the lower part of the handle 2, while the lower part of the handle 1 has a screw-threaded nut 19 secured in its open end.

[0013] The extension tube 23 is slidingly received in the corresponding open end of the upper part of the handle 2 in the upper unit 7, which is provided with a screw-threaded nut 20 in the open end of the upper part of the handle 1 , the nuts 19 and 20 being of opposite hand thread. An adjustment element 21 comprises a hexagonal nut 21 a from which extend on opposed sides threaded studs 21 b and 21 c of opposite hand threads. The adjustment element is held within agrip member 22 and the threaded studs 21 b and 21c are screwed into the corresponding nuts 19 and 20 so that, as the grip member 22 is twisted relative to the handle 1 the units 6 and 7 are drawn towards each other or urged away from each other depending on the direction of twisting.

[0014] In use, the roll is installed by twisting the grip member 22 to move the two units 6 and 7 apart, permitting the ends of the tubular core of the roll to be received in the recessed discs 14, 15. The grip member 22 is then twisted in the opposite direction to hold the core ends in the recesses in the discs, while still permitting rotation of the roll. The free end of the film from the roll is secured to the stack of objects to be wrapped and then the user walks around the stack, holding the dispenser in front of them, the film unreeling from the roll and winding on to the stack. Additionally, the twisting of the grip member 22 may serve to increase or increase the resistance to rotation of the roll and thus the tension of the wrapping material as it is applied.

[0015] Rolls with hollow cores can alternatively be mounted by means of supports received in the open ends of the core in place of the recessed discs 14, 15.
