[0054] FIGS. 24, 25 and 26 show three different types of part of the assist means that may be used in the present invention.
[0055] Referring to FIGS. 1-4, there is shown a roll 2 of dispensable sheet material 4. The roll 2 has an inner bore 6. The dispensable sheet material 4 is such that is has a free end 8 which is difficult to find for manual dispensation of the dispensable sheet material 4 from the roll 2.
[0056] Thus far described, the roll 2 of dispensable sheet material 4 may be any known roll 2 with the disposable sheet material 4 being in the form of adhesive tape.
[0057] In accordance with the present invention, the roll 2 is additionally provided with assist means 10 for assisting in the finding of the free end 8 of the dispensable sheet material 4. The assist means 10 comprises a band formation 12 which extends around the roll 2 by passing through the inner bore 6 and transversely over the width of the roll 2. The band formation 12 is movable around the roll 2 such that the band formation 12 is locatable on the roll 2 at a place to receive an end portion 14 of the dispensable sheet material 4 which contains the free end 8. The band formation 12 is thus able to indicate the position of the free end 8 and thereby facilitate the manual dispensation of the dispensable sheet material 4 from the roll 2.
[0058] The band formation 12 forms a low cost and an easy to use assist means for facilitating the manual dispensation of the dispensable sheet material 4 from the roll 2, and thereby avoiding or reducing user frustration in finding the free end 8 as would occur without the use of the band formation 12. As shown in FIG. 1, the band formation 12 has been placed such that the free end 8 extends circumferentially beyond the band formation 12 by a short amount. This ensures that the free end 8 does not become bent over and dirty. Alternatively, if desired, the band formation 12 may be placed such that the free end 8 terminates within the width of the band formation 12. The band formation 12 can be placed where desired by the user, providing that the placement of the band is always such that the user can easily find the free end 8.
[0059] FIGS. 1 and 2 illustrate a preferred method of use of the roll 2. More specifically, as shown in FIG. 1, the band formation 12 is underneath the dispensable sheet material 4 when the roll 2 is not in use. When it is desired to obtain some of the dispensable sheet material 4 from the roll 2, the band formation 12 is moved from the position shown in FIG. 1 to the position shown in FIG. 2. As shown in FIG. 2, the band formation 12 is on top of the dispensable sheet material 4. In order to obtain the required length of the dispensable sheet material 4, the free end 8 of the dispensable sheet material 4 is pulled away from the roll 4. As the free end 8 is pulled, the band formation 12 is caused to move clockwise around the roll 2. When the desired length of the dispensable sheet material 4 has been pulled up, the free end 8 can then be moved over the top of the band formation 12 as shown in FIG. 2, whereupon the band formation 12 is able to cut the dispensable sheet material 4. After the cut length of the dispensable sheet material 4 has been used, the band formation 12 is then moved over the new free end 8. The band formation 12 is then slid underneath the free end 8 of the dispensable sheet material and to the position shown in FIG. 1. In the position shown in FIG. 1, the roll of tape 2 is ready for a next use, and the positioning of the band formation 12 underneath the free end 8 of the dispensable sheet material 4 ensures that the free end 8 is not lost and is easily found for the next use of the roll 2.
[0060] As shown in FIGS. 1-4, the band formation 12 comprises a first part 14 and a second part 16. As can best be appreciated from FIG. 4, the first and second parts 14, 16 are separately formed from each other.
[0061] The first part 14 is for use in identifying the free end of the dispensable sheet material as described above with reference to FIGS. 1 and 2. The second part 16 is connected to the first part 14. The second part 16 passes through the inner bore 6. The second part 16 secures the first part 14 on the roll 2.
[0062] As best seen from FIGS. 3 and 4, the first part 4 has cutter means 18 for cutting the dispensable sheet material 4 when the dispensable sheet material 4 is pulled against the cutter means 18.
[0063] The first part 14 is a strip. The strip may be made of a soft plastics material, rexine, leather, cardboard or any other suitable material. The second part 16 is an elastic second part 16. The elastic second part 16 is a strip having a first end 20 and a second end 22. The first and second ends 20, 22 are secured to first and second end formations 24, 26 respectively on the first part 14. As shown in FIG. 4, the first and second ends 20, 22 are formed as knots. The first and second ends 20, 22 could alternatively be other abutment means such for example as studs.
[0064] FIG. 5 shows an alternative assist means 10 in the form of a band formation 28. Similar parts as in the band formation 12 have been given the same reference numerals for ease of comparison and understanding. It will be seen that the band formation 28 has the same first part 14 but a second part 30 which is not the same as the second part 16. More specifically, the second part 30 is a continuous elastic band which has been doubled back on itself and hooked around the first and second end formations 24, 26.
[0065] In FIG. 1-5, it will be seen that the cutter means 18 is in the form of a serrated knife blade edge. The cutter means 18 may alternatively be a straight knife blade edge.
[0066] Referring now to FIGS. 6 and 7, there is shown a second roll 32 of the present invention. Similar parts as in the roll 2 have been given the same reference numerals for ease of comparison and understanding. It will be seen that in the roll 32, the first and second end formations 24, 26 have been replaced by first and second end formations 34, 36 respectively. These first and second end formations 34, 36 are in the form of inclined slots as can best be appreciated from FIG. 7.
[0067] FIG. 8 shows an assist means 10 which is like the band formation 12 shown in FIGS. 6 and 7 except that the angle of the slots constituting the first and second end formations 34, 36 is steeper than in FIG. 7 as can be seen from a comparison of FIGS. 7 and 8.
[0068] Referring now to FIG. 9, there is shown a third roll 38 of the present invention. Similar parts as in previous Figures have been given the same reference numerals for ease of comparison and understanding. The roll 38 is such that the band formation is a continuous band 12. The continuous band formation 12 has no ends and it may be initially in the form of a strip which has been placed through the inner bore 6 and around the dispensable sheet material. The ends of the strip may then be secured together, for example by an adhesive or other securing means. The band formation 12 may be made of any suitable and appropriate material. Typically the material chosen will be such that the band formation 12 is easily able to be slid by a person around the circumference of the roll 2. The band formation 12 may be provided with a coating of a slide-facilitating material, for example Teflon (Registered Trade Mark).
[0069] As shown in FIGS. 1, 2, 6 and 9, the roll 2 is such that it includes a core 40 on which the dispensable sheet material 4 is wound. The core 40 is typically made of cardboard. The core 40 may be made of other materials if desired.
[0070] Referring now to FIGS. 10 and 11, similar parts as in previous Figure have been given the same reference numerals for ease of comparison and understanding. In FIG. 10, the dispensable sheet material 4 is clingfilm. The band formation 12 in FIG. 10 is longer than the band formation 12 shown in FIGS. 1, 2, 6 and 9 but the band formation 12 still extends around the roll 2 by passing through the inner bore 6 and transversely over the width of the roll 2. In FIG. 11, the roll 2 is similar to the roll 2 shown in FIG. 10, except that in FIG. 11, the dispensable sheet material 4 is foil. The foil is aluminium foil. Other types of foil may be employed, including various types of metalised plastics foils.
[0071] Referring now to FIG. 12, there is shown assist means 42 which is an alternative to the assist means 10. The assist means 42 comprises a band formation 44. The band formation 44 has a pair of ends 46, 48 which are tied together in a knot 50. The band formation 44 is thus a continuous band but one which has a grip formed by the ends 46, 48 and the knot 50. This grip is available for being gripped by a user in order to move the band formation 44 around the roll 2. The band formation 44 shown in FIG. 12 is an alternative to the band formation 12 shown in FIG. 9. The band formation 44 could be made longer if it were to be an alternative to the band formation 12 shown in FIG. 10 or the band formation 12 shown in FIG. 3.
[0072] Referring now to FIG. 13, there is shown a roll 44 of dispensable sheet material 46. The roll 44 has an inner bore 48. The dispensable sheet material 46 has a free end 50. The roll 44 is provided with assist means 52. The assist means 52 comprises a device 54 which extends at least transversely over the width of the roll 44. More specifically, the device 54 extends over the width of the roll 44, and it has bent ends 56, 58 which extend along the inner and outer sides 60, 62 respectively of the roll 44 in order to hold the device 54 on the roll 44. In an alternative embodiment of the invention, the ends 60, 62 may be bent again to extend towards each other along the inside of the roll 44.
[0073] FIG. 14 shows how the device 54 is wire-reinforced with a single length of wire 64. FIG. 15 shows an alternative assist means 66 having a device 68 which is reinforced by two wires 70, 72. FIG. 16 shows assist means 74 having a device 76 which is reinforced by a flat-sided strip of wire 78. If the metal reinforcement is of a soft pliable metal, then the ends of the device can easily be bent to different increasing lengths to ensure that the assist means remains firmly on the roll as the roll gets thinner due to the dispensation of the sheet material from the roll.
[0074] Referring now to FIGS. 17 and 18, there is shown a roll 80 of dispensable sheet material 4. The roll 80 has an inner bore 6. The dispensable sheet material 4 has a free end 8. As far described, similar parts as in previous Figures have been given the same reference numerals for ease of comparison and understanding.
[0075] The roll 80 has assist means 82 comprising a first part 84 and a second part 86.
[0076] The first part 84 is a four-sided structure having first and second sides 88, 90 which extend transversely over the width of the roll 80. The first part 84 also has third and fourth sides 92, 94 which extend along sides of the roll 2. Cutter means in the form of a serrated blade 96 is provided on the first side 88.
[0077] The first and second sides 88, 90 could be of the same or different cross sectional shapes. Triangular cross sectional shapes are shown in FIGS. 21 and 22. A rectangular cross sectional shape is shown in FIG. 23. The cross sectional shape could alternatively be a square cross sectional shape or any other desired cross sectional shape. FIG. 21 shows how the blade 96 is at the top of the first side 88. FIG. 22 shows how the blade 96 may alternatively be along one face of the side 88. The constructions shown in FIGS. 21, 22 and 23 can be used in any desired combination in the roll of the present invention.
[0078] FIG. 19 shows assist means 98. The assist means 98 is such that the third and fourth sides 92, 94 each comprises a pair of spaced apart arms 100, 102. One end 104 of the second part 86 is attached to the arm 102. The other end 106 is attached to the arm 100. The ends 104, 106 can be attached to different arms if desired. The second part 86 is an elasticated second part 86. The elasticated second part 86 may be a continuous band or simply an elasticated strip.
[0079] FIG. 20 shows alternative assist means 108 to the assist means 98 shown in FIG. 19. It will be seen that in the assist means 108, the arms 100, 102 have free ends which terminate in hooks 110.
[0080] In FIGS. 19 and 20, the blade 96 on the first side 88 has not been shown for simplicity of illustration. The blade 96 may be in various positions as mentioned above in connection with FIGS. 21, 22 and 23.
[0081] In all of FIGS. 17-20, the rolls 80, 98, 108 may be placed as desired in front of left or right handed users. Right handed users may typically orientate the roll of dispensable sheet material such that they pull the dispensable sheet material from the right. Left handed users may typically orientate the roll of dispensable sheet material such that they pull the dispensable sheet material from the left. In both instances, the blade 96 on the first side 88 is engaged for the purpose of cutting the dispensable sheet material to a required length. The second side 90 is then available for supporting the free end of the dispensable sheet material on the roll 4, so that this free end is easily identified and is able to be gripped for a next use of the roll 80, 98, 108.
[0082] FIG. 24 shows a second part 86 in the form of a continuous flat stretchable band. FIG. 25 shows a second part 86 having ends 112 which are tied together with a knot 114. FIG. 26 shows a second part 86 having size adjusting means 116. The size adjusting means 116 are shown in the form of rings but alternative devices may be employed.
[0083] The first part 84 of the assist means 82 shown in FIGS. 17 and 18, and the first part of the alternative assist means shown in FIG. 19 and in FIG. 20 may be moulded from plastics materials. Other materials may be employed if desired. The second part 86 as shown in FIGS. 24, 25 and 26 may be made of any suitable materials. The second part 86 can be shortened or, lengthened as desired, for example by redoing the knot 114 in the second part 86 as shown in FIG. 25, or by looping the second part 86 shown in FIG. 24 more than one time prior to attaching it to the first part 84.
[0084] It is to be appreciated that the embodiments of the invention described above with reference to the accompanying drawings have been given by way of example only and that modifications may be effected. Thus, for example, the dispensable sheet material 4 could be of a material other than single or double sided adhesive tape, clingfilm or foil. The band formations 12, 44 may be thicker or thinner than shown. The knot 50 could be replaced by another type of grip, with the grip being formed by a different type of knot 50 or alternatively a separately produced grip member. The shapes of the assist means shown in the drawings may be varied. The cutter means 18 may be another type of straight or serrated sharp edge. Individual components shown in the drawings are not limited to use in their drawings and they may be used in other drawings and in all aspects of the invention. The invention also extends to the individual components mentioned and/or shown above, taken singly or in any combination.
