Definitions

  • This invention relates to a device for severing a desired, variable amount of tape from a roll of tape. More particularly, the invention relates to a portable, reusable tape cutting and dispensing device.
  • tape dispenser is used in the art to refer * to devices which both "cut” and “dispense” tape and will be so used in this application.
  • the number of patents in this relatively simple technological field is indicative of the need for a simple, yet highly effective and safe tape dispensing device which may be re-used on a number of rolls of tape.
  • Prior art tape dispensers include one-piece, hand-held tape cutters which are . designed to be snapped over, or simply seated on, a roll of tape.
  • One such device is disclosed in Horn, U.S. Patent No. 3,970,230.
  • the Horn device relies on downward pressure from a single point of contact, the thumb, as the only means for the user to hold, control, and stabilize the device.
  • Other prior art devices include tape cutters with deformable legs which must be bent beneath the core of the tape roll to retain the cutter in position. Such deformable legs break frequently.
  • These and other tape dispensing and cutting devices include separate parts or members which must be man ⁇ ually positioned beneath the core of the tape roll to retain it in position on the roll.
  • Still other prior art devices include complex structures involving articulated or spring biased members which engage the interior of the core of the tape roll.
  • Not one of the prior known tape cutting and dispensing devices provides a simple, ergonomically formed device which provides the user with exceptional stability and control to effect safe and accurate cutting. . SUMMARY OF THE INVENTION
  • the tape dispensing and cutting device of the present invention is adapted to snap over a roll of masking tape or the like and be retained on the roll, affording a convenient tearing edge for severing the tape.
  • the device is preferably an egonomically formed one-piece molded plastic article comprising a top wall which rides over the periphery of the tape roll and two flexible side walls which depend from the top section and flank opposite sides of the roll of tape when the invention is positioned on a roll of tape.
  • Inwardly projecting shoulders are fixed to the front bottom surface of the side walls in opposing spaced relation and serve to spread the side walls apart as the tape dispenser is pressed down over a roll of tape. As the shoulders clear the inner core of the tape roll, the shoulders are snapped back beneath the core of the roll and serve to retain the invention on the roll of tape.
  • the top surface of the top wall is preferably provided with an ergonomically formed control recess which allows for exceptional con ⁇ trol and lateral stability of the invention, and facilitates forward and backward movement of the tape dispenser on the roll of tape.
  • the bottom edge of the side wall tapers downwardly from back to front along an arc of a circle so that the downward extension of the side wall from the top wall is greater at the front edge of the side wall than at the back edge.
  • Figure 1 is a perspective view of a tape dispensing device according to the invention positioned on a roll of tape, shown in phantom outline.
  • Figure 2 is a front plan view of a tape dispenser according to the present invention.
  • Figure 3 is a side plan view of the tape dispenser of the present invention positioned on a roll of tape, with the hand of a user shown in dotted outline.
  • Figure 4 is a side plan view of an alternative configuration of the tape dispenser of the present invention.
  • the tape dispenser of the present invention is shown generally in Figure 1 at 10 positioned on a roll of tape 11 having a core 13.
  • Tape dispenser 10 includes a top wall 12 having a top surface 14, and a bottom surface 16.
  • Top wall 12 also has a front edge 18, a back edge 20 and side edges 22.
  • the width of top wall 12 is slightly greater than the width of the tape roll on which it is used.
  • the length of top wall 12 and the relationship and size of all elements are humanly engineered in direct proportion to the natural grip of a per ⁇ son's hand and to fit the various generally available sized tape rolls.
  • Flexible side walls 24 are perpendicular to and extend downwardly from each of the side edges 22 of top wall 12.
  • Side walls 24 each have a top edge 26, a bottom edge 28, a front edge 30 and a back edge 32.
  • Top edge 26 of side walls 24 abu ts and is coextensive with side edges 22 of top wall 12, so that at the intersection of the side wall and top wall, the side wall extends the entire length of the top wall as shown in Figure 1.
  • Bottom edge 28 of side walls 24 is tapered or otherwise ergonomically shaped to allow the user to comfortably and conveniently grip and control dispenser 10.
  • the taper is downward from back edge 32 towards front edge 30 along an arc of a circle to thus de fine a smooth tapering surface, although other ergonomically shaped tapering or cutaway configurations which allow the tape dispenser to fit securely and comfortably in the apex between thumb and forefinger may also be used.
  • FIG. 4 One alternative configuration is shown in Figure 4, where side wall 24 has a generally L-shaped configuration.
  • bottom edge 28 is "tapered” or cutaway by having a first edge 29A which extends from back edge 32 towards, but terminating inwardly from, front edge 30 of side wall 24.
  • Bottom edge 29A is parallel to but spaced downwardly from top wall 12.
  • Bottom edge 29B extends from the inner terminal end of edge 29A and is perpendicular to edge 29A.
  • Bottom edge portion 29C connects bottom edge 29B to front edge 30.
  • a "tapered” or ergonomic cutaway portion is formed.
  • bottom edge 28 in Figures 1-3, or bottom edge 29A-C in Figure 4 also allows the downward extension of side walls 24 from top wall 12 to be greater at its front edge, as shown at 34, than at the back edge of side wall 24, as shown at 36.
  • bottom edge 28 tapers from near top edge 26 to near front edge 30, and thus includes connecting por ⁇ tion 28A which connects bottom edge 28 to front edge 30, it is within the scope of the invention to have the downwardly tapering bottom edge 28 extend from top edge 26 to front edge 30, while maintaining the ergonomically shaped form of the dispenser.
  • the downward extent 34 of front edge 30 is sufficient to span the full thickness of a tape roll on which it is to be used.
  • Tape dispenser 10 includes shoulders 38 perpendicular to and pro ⁇ jecting inwardly from the inner surface of side walls 24. Shoulders 38 are positioned near the intersection of the bottom edge and front edge of side walls 24 in opposing spaced relation. Sidewalls 24 are spaced a distance sufficient to allow sidewalls 24 to flank opposite sides of roll 11. This distance may, of course, vary to accommodate tape rolls of different size. Shoulders 38 serve to spread sidewalls 24 as dispenser 10 is placed on a roll of tape 11. After shoulders 38 clear the inner radial edge of roll 11, they snap back underneath the core and help to retain dispenser 10 on tape roll 11.
  • Top surface 14 of top wall 12 has a control recess 40 adjacent to back edge 20 of top wall 12.
  • Control recess 40 has sidewalls 41.
  • the control recess 40 extends approximately one- sixteenth (1/16) of an inch below top surface 14 and includes a curved front edge 42 to generally conform to the shape of the thumb.
  • a cutting edge is provided for severing tape.
  • the cutting edge is a blade 42 retained within a ' groove 44 on the inner surface of side walls 24.
  • cutting blade 42 is parallel to and substantially coextensive with top surface 14 of top wall 12.
  • a serrated edge blade is shown and is the pre ⁇ ferred blade for generally cutting tape, a spike, pointed, or a pyramid- shaped blade may be preferred for cutting certain types of tape, such as vinyl tape.
  • dispenser 10 is molded in one piece from plastic or similar materials.
  • light gauge metals or the like may also be used.
  • blade 42 may be integrally formed as part of dispenser 10 rather than a separate piece inserted in groove 44, as shown.
  • dispenser 10 is snapped onto a roll 11 and may be freely placed at any position on the roll. Dispenser 10 is readily guided about roll 11 by a user's thumb in control recess 40. Sidewall 41 allows the thumb to laterally stabilize dispenser 10.
  • dispenser 10 and roll 11 may both be grasped firmly in the apex of thumb and forefinger to provide a large surface area of support for dispenser 10 which provides stability and control while severing the tape.
  • control recess 40 allows the user's thumb to not only pro ⁇ vide downward pressure in opposition to the fingers, but to also pro ⁇ vide lateral support and stability during tape tearing.
  • Recess 40 also allows the user to adjust the position of dispenser 10 on the tape roll to cut precisely the desired amount of tape. After roll 11 is depleted, dispenser 10 is readily removed by spreading sidewalls 24 and may be reused.

Abstract

Un dispositif ergonomique de distribution et de sectionnement (10) d'un ruban s'adapte et se fixe sur un rouleau (11) de ruban pour masquer ou similaire, et présente un bord tranchant (42) utile pour sectionner le ruban. Le dispositif (10) se compose de préférence d'un article en plastique moulé en une seule pièce comprenant une paroi supérieure (12) qui chevauche la periphérie extérieure du rouleau (11) de ruban et deux parois latérales flexibles (24) qui pendent de la paroi supérieure et côtoient des côtés opposés du rouleau (11) de ruban lorsque l'invention est montée sur celui-ci. Une lame tranchante (42) peut être fixée au distributeur (10), ou intégralement formée avec celui-ci. Des épaulements intérieurs (38) sont fixés à la surface inférieure antérieure (28) des parois latérales (24), l'un en face de l'autre, et servent à écarter les parois latérales (24) lorsque l'on presse le distributeur et sectionneur (10) de ruban sur un rouleau de ruban (11). Lorsque les épaulements (38) dépassent la bobine intérieure (13) du rouleau (11) de ruban, les épaulements (38) reviennent brusquement sous la bobine (13) du rouleau (11) et aident à retenir l'invention sur le rouleau (11) de ruban. La paroi supérieure (12) comprend un creux (40) de commande pour le pouce qui sert à augmenter la maniabilité et la stabilité du dispositif. Les parois inférieures (24) se rétrécissent en arc de cercle dans leur partie inférieure pour que le dispositif (10) s'adapte confortablement et fermement entre la pointe du pouce et l'index.
