DETAILED DESCRIPTION OF THE INVENTION
The drawings show an open faced housing shell 1 comprising a support surface with a peripheral wall extending transversely from the support surface. The housing fits in the palm of one hand and is supported and gripped by the fingers of one hand. The housing may be constructed of any suitable material such as thermoplastic. The housing contains a hub 2 (preferably hollow) including spring fingers 9 (or other means for retaining a tape roll on the hub) upon which an adhesive tape roll 11 wound around a spool 12 is mounted. A tape roll 11 on a spool 12 is snapped over the spring fingers 9 which prevent the tape roll 11 from slipping off the hub 2 whilst allowing the tape spool 12 to rotate freely. The outer diameter of the hub 2 and the inner diameter of the spool 12 are such that the spool 12 may rotate about the hub 2. The outer diameter of the tape roll 11 is slightly smaller than the internal dimensions of the housing shell 1 such that it fills the space almost completely thus allowing the dispenser to be handled and manipulated more
easily by the user. A preferred embodiment of the dispenser would dispense standard width 0.50 inch (12.7mm) wide and 0.75 inch (19mm) wide adhesive tape in lengths between 300 inches (7.62m) and 1400 inches (35.59m) on standard, approximately 1.00 inch (25mm) internal diameter, spools in common use in homes schools and offices. The mechanism described herein is scalable and may readily be adapted to accommodate any width and size of tape roll however, tape rolls over 3.0 inches (75 mm) wide would generally be considered unwieldy for single handed operation.
As can be seen from FIG.l the housing shell 1 also comprises a tape discharge opening 13 which comprises a variable size opening between a dispenser lip 15 formed in the peripheral wall of the housing shell 1 and a lever mechanism 3 pivotally mounted near the discharge opening 13, the dispenser lip 15 comprises a raised area of the peripheral wall of the housing shell 1 at the tape discharge opening 13 and to which a small section of unreeled tape is pressed and adhered by rotation of the depressor lever 5. The lever mechanism 3 provides a tape locking device whilst tape is being cut thereby preventing tape from unreeling, and a tape anti lock device preventing the tape from locking or adhering to the housing whilst tape is being applied. The lever mechanism 3 also secures the new tape end 14 preventing it from withdrawing into the housing shell 1 when not in use.
The lever mechanism 3 comprises two levers pivotally mounted approximately diametrically and radially about a spindle 8. The spindle 8 includes spring fingers 10 over which the lever mechanism 3 is snapped to enable rotation loosely about the spindle 8. The levers include a tape depressor lever 5 and a tape cutter lever 6. The tape depressor lever 5 is oriented towards the tape roll 11 and, when actuated by movement of the cutter lever, provides a means of depressing tape unreeling from the tape roll 11 so as to squeeze a small section of tape against the dispenser lip 15 at the tape discharge opening 13 adhering it thereto. The cutter lever 6 is oriented downstream of the discharge opening 13 and includes at its extremity a cutting edge 7 comprising a serrated edge including a plurality of teeth for cutting unreeled and applied adhesive tape. In this preferred embodiment the lever mechanism 3 includes a tape guide applicator 4 located on the underside of the lever mechanism 3, the tape guide applicator 4 having a curved pressing
surface located between the cutter lever 6 and tape depressor lever 5. In an alternative embodiment the guide applicator 4 is mounted independently from the lever mechanism 3 or as an integral part of the housing shell 1 in the proximity of the lever mechanism 3.
At the commencement of a taping application a user presses the tape guide applicator 4 against a tape end 14 protruding from the discharge opening 13 against a substrate surface with the adhesive face against the substrate. Pressing the tape end to the substrate causes the adhesive tape to adhere to the substrate and, as the user draws the tape dispenser back across the substrate; adhesive tape unreels from the tape roll 11 and passes smoothly under the tape guide applicator 4 adhering tape to the substrate as is shown in FIG. 3 When a requisite length of tape has been applied, the housing shell 1 is tilted to an inclined plane as is shown in FIG.4 whilst the user maintains pressure on the guide applicator 4. This causes the cutting edge 7 to engage the tape at the substrate and the lever mechanism 3 to pivot about the spindle 8 and press the depressor lever 5 against the unreeling tape causing a small section of the unreeling tape to be squeezed against, and adhered to, the dispenser lip 15 at the discharge opening 13 thereby preventing the tape roll 11 from unreeling further. Further tilting of the housing shell 1 accompanied by slight backward pressure on the housing shell 1 against the direction of travel causes the tape to sever at the cutting edge 7. When the tape is severed the depressor lever 5 stops squeezing the tape against the dispenser lip 15 however, the new tape end remains lightly adhered to the dispenser/applicator at the dispenser lip 15 preventing the protruding tape end 14 from retracting into the housing shell 1. At the commencement of the next taping application the small section of tape lightly adhered at the dispenser lip 15 becomes detached when the protruding tape end 14 is applied to a substrate and the housing drawn backward during the next taping application.
The position and length of the depressor lever 5 is such that it is prevented from closing the discharge opening 13 whilst tape is being applied by reason of the depressor lever 5 bearing upon the unreeling tape, which is under tension as it unreels thereby restricting rotation of the depressor lever 5 and consequential closing of the discharge opening 13.
The lever mechanism 3 enables adhesive tape to be applied to substrates in any orientation - horizontal, vertical and inverted. The embodiment shown in the drawings
includes wide lugs 16 on the hub 2 spring fingers 9 angled as shown to provide support for the users thumb when dispensing tape in hand held mode. The preferred method of gripping and supporting the dispenser whilst in hand held mode is with the thumb on the hub spring finger lugs 16, the middle finger on the outer face of the housing shell 1 in the vicinity of the hub 2 mounting and the index finger upon the housing shell 1 above the lever mechanism 3 where a shallow depression 17 is provided to support the index finger.
This tape dispenser/applicator also removes a common problem with hand-held tape dispenser/applicators which is contamination of the tape end. This dispenser may be inverted to stand on a stable surface with the protruding tape end 14 uppermost as shown in FIG.5. keeping the protruding tape end 14 clear of potential contaminants.
FIG.2 shows the lever mechanism 3 with a guide cheek 18 included on the outer edge of the depressor lever 5 which purpose is to ensure correct tape position on the guide applicator and preventing unreeling tape from slipping off the lever mechanism 3.
The drawings show the preferred embodiment of the tape dispenser/applicator having only two parts enabling manufacturing cost efficiencies and ease of tape roll replacement. Other embodiments of this tape dispenser/applicator may include a two or more part closed shell and/or other decorative or support structures.
The lever mechanism 3 enables the tape dispenser/applicator to be used as a desk top tape dispenser as shown in FIG 5 by simply inverting the dispenser so that the lever mechanism 3 is uppermost. Tape is dispensed by the user pulling a protruding tape end 14 from the discharge opening 13 with the user's fingers. When the requisite length of tape is dispensed, the user pulls the tape end 14 in a downward motion across the cutter lever 6 whereby the tape is locked by the depressor lever 5 at the dispenser lip 15 preventing unreeling of the tape roll 11 as previously described and the tape is severed at the cutting edge 7. The new protruding tape end 14 is lightly adhered at the dispenser lip 15 preventing retraction of the protruding tape end 14 into the housing shell 1 as previously described and ready for it next use The tape locking and anti lock mechanism described herein may be incorporated into much larger, heavier or more ornate desktop dispensers when used only in the desk top mode.
EXPLOITATION OF THE INVENTION IN INDUSTRY
Billions of rolls of adhesive tape and tape dispensers (disposable and refillable) per year are used in schools, homes, offices and other workplaces. Most adhesive tape dispensers are the familiar "snail shaped" clear plastic dispensers which sit on a surface and dispenses tape. This invention, with has as few as two components, has the advantage that it permits tape to be repeatedly dispensed, applied to a surface and locked whilst cutting, with no tape retraction between applications and requires only one handed operation. It also operates as a desktop dispenser but with an added advantage that the tape end protrudes providing ease of use. This invention may be manufactured using injection molded clear plastic as inexpensively as many of the "snail shaped" dispensers in worldwide which use standard size tape spools and as a result has the potential to replace all current tape dispensers including the bulkier parcel tape size applicators and other more elaborate tape applicators.

The method of dispensing arid applying adhesive tape having an adhesive side and a non adhesive side onto a substrate and cutting said adhesive tape comprising the steps of; positioning a roll of adhesive tape in a housing shell (1) in a manner to allow rotation of said roll; and mounting a lever mechanism (3) on said housing shell (1) to provide tape locking and anti locking means, wherein levers are mounted on a lever mechanism (3) in a predetermined position about a mount, said lever mechanism (3) including a tape cutter lever (6) arranged so as to move a tape depressor lever (5), said cutter lever (6) having a cutting edge (7) at its extremity, said lever mechanism (3) mounted such that it bears upon tape unreeling from said tape roll (11) and, said tape depressor lever (5), whilst bearing upon the unreeling tape, is caused to move as said tape tensions whilst adhesive tape is applied to a substrate and the housing shell (1) is drawn back across said substrate; and the movement of said depressor lever (5) prevents closure of said tape discharge opening whilst said tape remains under tension (13) thereby enabling unreeling tape to pass through said discharge opening (13) whilst tape is being dispensed; and at the commencement of a taping application a tape end (14) protruding from said discharge opening (13) is adhered to a substrate surface by the user pressing said tape end (14) against said substrate using said tape guide applicator (4), comprising an element of said lever mechanism (3); and by drawing said housing shell (1) backwards across said substrate causes tape to adhere to said substrate as it unreels from said tape roll (11); and when a requisite length of tape is applied, said housing shell (1) is rotated about said lever mechanism (3) whilst maintaining said cutter lever (6) in contact with the substrate causing said cutting edge (7) to engage the applied tape and, continued rotation of said housing shell (1), causes said lever mechanism (3) to move on its mount causing said depressor arm (5) to close said discharge opening (13) by squeezing a section of unreeling tape against, and adhering said tape to, said housing shell (1) thereby preventing said tape roll (11) from unreeling; whereupon, continued rotation of said housing shell (1) about said cutting edge (7), accompanied by backward pressure on said housing shell (1), causes the tape to sever at said cutting edge (7); whereupon said tape depressor lever (5) ceases squeezing the tape against said housing shell (1) leaving a new tape end adhered to said housing shell (1) thereby preventing said new tape end from rolling back to said tape roll (11) or into said housing shell (1) and ready for a new taping application; and at the commencement of a new taping application said tape end adhered to said housing shell (1) becomes detached, by peeling away from, said housing shell (1) by the previously described action of applying said tape end to a substrate and the drawing of said housing shell (1) backward across said substrate.
9. Tape dispenser according to claim 8 characterized in that said tape dispenser functions as a desk top tape dispenser by inverting said dispenser housing shell (1) with said lever mechanism (3) uppermost; and providing a support structure for the inverted dispenser enabling it to stand when placed on a horizontal surface wherein tape is withdrawn from the housing shell (1) by the user pulling a protruding tape end (14) from said discharge opening (13) and across said lever mechanism (3) with the users fingers, the tape is pulled downward across said cutter lever (6) thereby locking the tape at the depressor lever (5) preventing tape from unreeling as the tape is severed at said cutting edge (7).
10. Tape dispenser according to claim 8 characterized in that said tape guide applicator (4) is mounted independently from said lever mechanism (3).
