The present invention relates to an improved scissors. There are many types of scissors available currently for use in cutting many materials such as paper, fabric, cloth, plastic sheeting, tape and many other examples of material in common everyday use. There are also many types of scissors used in medical and hospital environments.
Adhesive backed film, tape and other binding materials are supplied in rolls of various diameters and widths. When one uses a scissors to cut a length of tape cleanly from the roll a difficulty arises in that when the edge of uncut tape sticks back on the roll, it is very difficult to locate the edge and lift the edge of the tape. This is a particularly major problem when the tape or film is of transparent adhesive tape such as that commonly sold under the trade mark SELLOTAPE and 3M. There is also a major problem with the contamination of medical/surgical adhesive tape in medical environments when a person's fingers, whether gloved or bare, can transfer bacteria onto the adhesive tape, when the person is cutting the tape with a scissors or is tearing the tape with their fingers. Numerous attempts have been made to solve this problem which usually consists of gadgets or devices for applying tape and to which the edge of the uncut tape can adhere to after cutting. These gadgets and devices can be cumbersome and not inexpensive.
The object of the invention is to alleviate the problem associated with the dispensing of tape or film from rolls of such material which is easy to operate and inexpensive and also to alleviate the problem of contamination of tape in a medical and hospital environment.
The present invention provides a scissors for cutting adhesive tape or film which is dispensed from a roll, the scissors including a curling device having a contact surface mounted on at least one blade of the scissors to which the free edge of the tape or film can adhere to after cutting, enabling the user to manipulate the scissors to form a curl, fold and/or hold the free edge of the tape or film, so that it can readily be picked up for subsequent use, whereby the scissors of the invention may be used to cut, curl, hold and/or fold the free edge of the tape or film. When cut, the roll of tape or film will not fall as is likely to happen in the prior art. The scissors of the invention is more efficient than the prior art devices. It is also more hygienic when used in the medical/surgical field. No finger marks are left on the sticky side of the tape which helps to reduce possible contamination. Advantageously, the curling device has edges, protrusions, knuckles or ribs with a contact surface for the free edge of the tape or film.
Conveniently, the curling device is provided on both blades of the scissors.
The curl formed by the curling device sticks to the adhesive of the tape and prevents it from recoiling.
Preferably, the scissors comprises a first cutting blade having a handle and a finger insert; a second cutting blade having a handle and a finger insert; the first and second cutting blades being secured together at a common pivot point, the curling device being mounted on the first cutting blade, the curling device having three knuckles or curves located about its circumference for contact with an adhesive tape. Conveniently, a void or depression is provided between the knuckle adjacent the blade.
Ideally, the curling device is mounted to the blade so as to be level with the edge of the blade.
The curling piece may be of a solid construction and is fixed or glued to the side of the blade of the scissors.
Alternatively, the curling piece is of hollow construction and is fixed or glued to the side of the blade of the scissors. Optionally, the curling device is provided with a plurality of studs which are engageable with complementary orifices provided in the side of the blade of the scissors; or the curling device is provided with a plurality of snap fasteners engageable in complementary slots provided on the edge of the blade of the scissors; or alternatively the curling piece is provided with a snap engaging grip engageable about the blade and is held in position by a fastener pivotally connecting the two blades of the scissors.
In another alternative embodiment, the curling piece comprises a separate contact element mounted on each blade of the scissors and which co-operate to engage the tape to form a curl, hold and/or fold the free edge of the tape or film and in a further alternative embodiment the curling device comprises a spring loaded barrel mounted between a pair of receivers provided on the blade of the scissors.
Advantageously, a spring assist opening device is mounted on a handle of the scissors and is operable to bias the scissors into an open position after a cutting action. The invention will hereinafter be now particularly described with reference to the accompanying drawings which show, by way of example only, a number of embodiments according to the invention.

Referring to the drawings, the first embodiment 1500 is shown in Figures 1 to 3 and includes an elongate curling device 1514, which is a solid piece and is fixed or glued to the blade 1501 . A roll of tape 1520 engages across the curling member and when released therefrom forms a curl 1521 . The curling device 1514 has three knuckles or curves 1515, 1516 and 1517 and a void 1518 between knuckle 1515 and the edge 1520 of the blade 1501. It is believed that the void 1518 helps the curl to form. The curling device 1514 is level with the edge 1520 of the blade 1501 which helps to prevent accidental injury. Also the point of the blade of the scissors is less dangerous. The second embodiment 1600 is shown in Figures 4 to 6, includes an elongate curling device 1614, which is of hollow construction, and is fixed or glued to blade 1601 of the scissors. In the modification of the second embodiment 1600 shown in Figures 5 and 6, the curling device 1614 is provided with three separate studs 1627 which are engageable with three corresponding holes 1619.
Referring to Figures 7, 8 and 9, the third embodiment 100 of scissors according to the invention comprises a first cutting blade 101 , a first handle 102, a first handle finger insert 103, a second cutting blade 104, a second handle 105, and a second handle finger insert 106. The blades 101 and 104 and handles 102 and 105 are secured together by a rivet 107 which are covered by a pair of rivet covers 108.
Secured to the outer face 1 10 of the left handle 102 is an elongate curling device 1 14 which is provided with three smooth rounded edges or knuckles 1 15, 1 16 and 1 17 for making contact with the free edge of an adhesive tape 120 extended from a roll 122 of adhesive tape. A void 1 18 is located between knuckle 1 17 and the edge 125 of the blade 101.
To use the scissors, the user cuts the tape 120 as close to the roll as possible as shown in Figure 9B and not as shown in Figure 9A. As shown in Figure 9C a left handed user grasps the scissors 100 as shown in Figure 9C. After cutting the desired length of tape, the user turns the scissors 90 degrees in an anti-clockwise direction so that the free end of the tape sticks to the smooth rounded edge or knuckle 1 15 and the curling device 1 14 and the scissors 100 away from the tape, so the tape is forced from contact with the curling device to form a curl on the end of the tape. Alternatively, the tape can be pulled from the scissors so as to form the curl on the tape.
