' DRY-ADHESIVE TAPE ROLL' DISPENSER Filed April 13, 1945 FIE, 1.

INVENTOR, M'Ziozz Kaizrz,

Patented May 2 8, 1946 DRY-ADHESIV E TAPE ROLLDISPENSER Milton Kahn, Mount Vernon, N. Y., assignor to The Cofax Corporation, Long Island City, N. Y., i a corporation of New York Application April 13, 1943, Serial N 0. 482,873

2 Claims.

This invention relates to a device for holding and therewith dispensing a portion of tape from a dry adhesive tape roll. The handling of such rolls and severance of sections of tape therefrom involve considerable difficulties and inconveniences, due to the character and nature of this material.

The principal object of the invention is to provide a device for the above purpose, which will be conveniently and economically manufacturable, saleable at low cost, conveniently utilizable, strong, durable, and wherewith the tape roll may be eificiently carried and sections thereof severed with ease and without loss.

Another object is to provide a dispenser of the above type which is devoid of moving parts, which may be made entirely of plastic with a minimum bulk of such material for accommodating a given size of roll and which is yet inherently amply strong to withstand the strain imposed in the tape dispensing and severing operation.

Other objects and advantages will hereinafter appear.

In the accompanying drawing:

Fig. 1 is a perspective view showing the dry adhesive tape roll dispenser, constituting the invention.

Fig. 2' is a plan view of the dispenser shown in Fig. 1.

Fig. 3 is a front elevation of the dispenser.

Fig. 4 shows a cross-sectional elevation of the dispenser, taken on line 4+4 of Fig. 2.

The'dispenser I comprises a unitary integral 7 body of plastic material having a base 3, and a coaxial hollow stud 4 extending upwardly therefrom, and carrying a toothed cutter bar 5. Shoulders 1 are located at the ends of said cutter bar and project beyond th cutting conformation, preferably a line of cutting teeth, as shown. The cutter bar 5 is parallel to the axis of the dispenser and its lower or root end is an integral lateral protuberance from the periphery of the base .3. Integrally with the cutter bar and preferably along the full length thereof extends the outer end of a curved wall 2 which rises progressively from the point l6 on and thence along the pe-' riphery of the base, its upper edge thus extencl with. While the height of the cutter teeth extends radially of the dispenser, the ledge 6 extends preferably at right angles to the teeth, generally tangentially of the dispe er d inward from the cutter toward the discharge web I ll of the spool of tape. The stud 4 is adapted to receive the core 8 that carries the roll 9 of dry adhesive tape it, whereby said roll is capable of rotating about said stud in an anti-clockwise direction, as viewed in the drawing, for unrolling the tape. The top of the stud 4 is provided with a central hole II, and a disk I2, having a diameter larger than said stud but preferably smaller ing along a helix I! as shown. The curved wall 2 thus constitutes a web binding the length of the cutter bar to the base and serves as a buttress resisting the strain applied at the cutter bar 5 inuse of the dispenser. The device is also provided with a rounded ledge 6 which is of substantially the length of the cutter bar 5 and is adjacent and parallel to said bar and integral therethan that of the roll 9, carries a lug l3 which is wedgingly insertible into and removable from the hole H, by which means the disk [2 may be mounted upon the stud 4 to thereby retain the roll against removal thereof from the stud 4, as showninFig.4.

In the handling of the tape roll 9, for severance of lengths of dry adhesive tape therefrom, it is vital to maintain a fragment Illa of the tape at all times away from the roll, otherwise such fragment and its terminal accidentally adhere to the roll, rendering it diflicult and annoying to separate the former from the latter when it is desired to dispense the tape from the roll. Also, for efiiciently cutting oil the lengths of tape from the roll 9 it is preferable to apply a hold upon the tape close to the intended lineof. severance.

When it is desired to remove a length of tape from the roll, the section required is unrolled and its intended terminus is brought over to the cutter 5. The user holding the entire device with one hand then applies the thumb upon the tape portion lb and Dresses it against the ledge 6 of the device, while drawing the unrolled length of tape across the cutter 5 with the other hand. The temporary adherance of the tape portion [0b to the ledge 6 aids in the fficient severance of the tape with utilization of the cutter 5, while at the same time this adhered condition of the tape portion lllb to the ledge 6 serves to retain a leading fragment of the tape Illa away from the tape roll 9 proper, thereby at all time providing an initial unattached tape fragment Illa necessary for a succeeding removal of a subse quent tape length.

When it is desired to adhere a preliminarily ine determinate length of tape l0 upon a surface Fig. 1, the disposition ofthe rolls on thebase 8 is first reversed. by lifting. olf the disk, removing the roll, and replacingitin turned-over state about the stud I. so that theback Hid opposite adhesivlll'c of the unrolling tape now faces the ledge 6. A portion of the tape is then unrolled and its end We is adhered to the location required. The dispenser may be then held in the position illustrated in Fig. 1, with its shoulders I bearin upon the surface I4, and in this position advanced to unroll the tape until reaching the desired place for applying the terminus of the required length of tape to be used, whereupon the said length may be severed with the cutter 5. While thus advancing the dispenser in the described manner, the shoulders I serve to maintain the leading portion l0 of the tape slightly away from the surface l4, thereby efficiently positioning the cutter 6 for severance of the oncoming terminus of the needed tape-length, by a slightly lateral twist of the cutter and simultaneous yanking pull of the dispenser away from the adhered tape length Illa. The shoulders I also serve to accurately align the unrolling tape length with the roll 9, both for tearing ofi a section thereof and while applying it in the manner shown in Fig. 1.

Variations may be resorted to within the scope of the invention.

Having thus described my invention, I claim:

1. A unitary dispenser for a dry adhesive tape roll comprising a base disk, an uprising hollow stud coaxial therewith for accommodating a tape roll thereon, an upright cutter bar rising from said base and integral therewith, having a cutting conformation extending radially outward from said base, a curved wall extending progressively upward from said base along the periphery thereof, with its end unitary with the cutter bar and of substantially the height thereof, said cutter bar having a lateral ledge extending at an angle to the cutter conformation in the direction opposed to said web.

2. A dispenser for a dry adhesive tape roll comprising a base disk, an uprising hollow stud coaxial therewith for accommodating a tape roll thereon, an upright cutter bar rising from said base having a cutting conformation extending radially outward from said base, a curved wall extending progressively upward from said base along the periphery thereof with its end unitary with the cutter bar and of substantially the height thereof, said cutter bar having a lateral ledge extending at an angle to the cutter conformation in the direction opposed to said web, the upper and lower ends of said cutter bar having shoulders protruding beyond the cutting conformation, said dispenser being an integral plastic structure, said dispenser having a removable cover disk concentric with the stud and of diameter to overlap a part of the tape roll.
