DISPENSER FOR ADHESIVE TAPE OR STRIP Filed July ll, 196].

191820 3 `l(7/ 6 IZ United States Patent @ce 3,132,783 DISPENSER FOR ADHESIVE TAPE R STRIP Colin Ronald Duncan, 2 Osbum Ave., North Balwyn,

Victoria, Australia Filed July 11, 1961, Ser. No. 123,189 Claims priority, application Australia Dec. 1, 1960 3 Claims. (Cl. 22S-25) This invention relates to an improved dispenser for adhesive tape or strip wound in roll form, and particular# ly tape or stripof the pressure sensitive adhesive type used is tacky on one cutting the tape or strip is often not as elcient as desired.

The present invention has for its object to provide an improved type of dispenser by means of which adhesive tape or strip `can be readily applied without sticking to itself or tangling and also providing means whereby the tape may be severed from the roll quickly and efciently when desired.

According to the invention, the improved dispenser comprises a casing adapted to be held in the hand, means in said casing for supporting a roll of (the adhesive strip or tape, a nose surface on said casing for applying pressure on the tape or strip to cause it Ito adhere to the surface Ito which it is to be applied, and a depressible cutter adapted to operate on the itape or `strip at a point between the nose surface 4and the roll yto sever said tape or strip.

The linvention is more fully described ,aided by reference to the accompanying drawings wherein:

FIG. 1 is a perspective view of the improved dispenser.

FIG. 2 is an exploded view of the casing separated into its two component parts to show the internal construction.

FIG. 3 is a longitudinal section of fthe dispenser.

FIG. 4 is an underside plan View.

FIG. 5 is a section taken on line 5*5 of FIG. 3.

As is shown in these Niews, the dispenser comprises a casing 1 consisting of two component pants 2 and 3 preferably `formed as pressure mouldings from a suitable plastic such as nylon. The two parts are detachably secured together by any suitable means such as, for instance, by integral moulded studs 4 on fthe part 3 engaging sockets moulded on the part 2.

The casing is open at the bottom 6 to accommodate the roll 7 of adhesive tape o-r strip 8 and, at its forward end, it is provided with Ia curved nose-like portion 9. Preferably the casing has 4a generally curved rtop 10 which is formed integrally with the part 2 and two at sides 11 and 12 so that it is convenient fto hold in the hand.

'The roll 7 is supported on a hollow cylindrical support member 13 moulded integrally with the part 2 and preferably a light leaf brake spring 14 is tted in slots 15 in said member 13 and has a protruding end 16 adapted to be depressed by the roll 7 when it is applied. Said end, by exerting pressure ou the internal Surface of 'the roll, retards its rotation sufficiently to prevent uncontrolled rotation. The spring 14 may 'be retained in position in the slots 15 by a short cylindrical projection 17 moulded on .the part 3 and of such diameter and length `that it closely 'fits within the hollow cylindrical member 13 and latenally engages the spring when the -two parts are united.

Supported by the top of the casing is a spring cutter blade 18 provided at its forward end with a downturned V-shaped cutting edge 19. The cutter preferably consists of a spring steel arm 20 anchored at its rear end 21 to the casing and acted on at its forward end by a depressible push button 22 slidably extending through M 3,132,783 PatentedMay 12, 1964 depress the cutter and bring its cutting edge 19 into use.y

The cutting edge 19 is preferably termed with a sharp central point 23 and two angular cutting edges 24, one on each side of the central poi-nt. g

'Ihe rear end oi the arm 20 may be anchored in any convenient manner such as by forming a downturned lip 25 on the end 21 and providing a complementary slotted socket 26 on the casing part 2 to receive said end and lip, see lFIGS. 2 and 3. The casing pant 3 may have a short lug 27 to engage the end 21 ofthe arm 20 and retain it in the socket 26. y y A The tape yor strip Sextends from the roll 7 under a curved yguide 28 and thence across a throat 29 to beneath a curved applying surface 30 on the rounded .I nose-like portion 9. The cutting edge 19 off. the cutter operates in fthe throat 29iand -acts on the portion of the tape or `strip extendingacross said .throat from the guide 28 to the curved applying surface 30 of the rounded nose portion 9. j

In using the dispenser, the end of the tape or strip 8 is first drawn `from the roll 7 with the adhesive surface downwards and after passing beneath thel guide 28 is applied to the surface to which it is to be attached. 'libe dispenser Vis then moved along the surface to unwind tape or strip fromy the roll against the resistance of the brake spring 14 and the curved applying surface 30 slidably pressed upon the tape or strip as it is being applied to smooth it and ensure its proper adhesion. After the required length of itape or strip has been applied, the linger button 22 is depressed causing the pointed cutting edge 19 of the cutter to move into the throat 29 and pierce and sever the Itape or strip at the point between the guide 28 and fthe applying surface 30. The cutter operates without a shear edge, the central point 23 irst piercing the relatively taut tape or strip and the angular cutting edges 24 completing the severing operation. The inherent springiness of fthe unitary cutter arm 20 returns the pointed cutting edge to normal position as soon as the pressure on the finger button 22 is released.

To maintain the severed end of the tape or strip in conveniently accessible position, an abutment or ledge 31 may be provided lad-jacent Ito lthe curved guide 28, the tape or strip passing between said abutment or ledge 31 and said yguide as shown Iin FIG. 3. After the tape or strip has been severed, the cut end adheres -to the abutment or ledge 31 and is thusconveniently accessible for the next application.

The abutment or ledge 31 and also fthe curved guide 28 may be formedin two half-sections moulded integrally with the two casing parts 2 and 3 and co-registering when the casing parts are united.

for inserting a fresh roll 7 when the existing roll becomes exhausted.
