Application September 4, 1952, Serial No. 307,795

6 Claims. (Cl. 21633) 'I'he present invention relates to devices for holding and dispensing or applying tape material and embodies, more specifically, an improved form'of tape dispensing mechanism of such structure that it may be formed by simple stamping and forming operations out of material in blank form.

In applicants co-pending applications Serial No. 297,459, tiled July 7, 1952, for Tape Applicator; Serial No. 305,229, led August 19, 1952, for Roll of Tape with Cutter Blade; and Serial No. 303,587, led August 9, 1952, for Pistol Grip Tape Applicator, there are described mechanism by means of which tape material may be conveniently dispensed or applied to a desired surface. This invention carries forward certain basic features of applicants above mentioned earlier inventions and incorporates therein additional advantageous features as, for example, the structure above alluded to by means of which the device may be formed by stamping operations 2,723,774 Patented Nov. 15, 1955 ICC ` is shown at 10, having transverse cuts 11 and 12 formed and preferably in such fashion that no waste material is produced out of the material of the blank.

A further object of this invention is to provide a device of the above character wherein the end of the tape material adjacent the severed edge is maintained effectively against return to the roll and bent in such fashion that the adhesive material on the tape (if the tape material is adhesive) is held so that it will not easily come accidentally into contact with randomsurfaces but rather, held so that it may easily be applied to a desired surface when the tape is to be again utilized.

Yet anotheradvantage of v'this invention is to provide a device of the above character wherein the tape cutting or severing element is positioned in a more effective location to accomplish the' desired cutting operations.

A further object of the-invention is to provide, in cornbination with the foregoing, a convenient holder by means of which assorted size rolls oftapes may be inserted4 and utilized to replace similar or different size rolls as desired.

0ther and further objects of this invention4 will Vbe apparent as the invention is described in detail in connection with the accompanying drawings, wherein Figure 1 is a plan view of a blank of material out of which a tape holder and dispenser is to be formed in accordance with this invention, the fold lines being shown dotted while the lines of cut are shown in solid lines;

Figure 2 is a view in side elevation of the device formed from the blank of Figure 1;

Figure 3 is a view in end elevation looking from the left in Figure 2;

Figure 4 is a top View of the device as shown in Figures 2 and 3;

Figure 5 is a view in section, taken on line 5-5 of Figure 3, and looking in the direction ofv the arrows, this view showing a roll of tape inserted into the holder; and

Figure 6 is a view in side elevation showing the manner in which the device is used to apply tape to a desired surface.

`Referring more particularly to Figure l, a blank of a therein between which a fold line 13 extends. Preferably these and other cuts are narrow slots dened by closely spaced edges 11a, 11b and edges 12a and 12b.

The blank 10 is also cut longitudinally to form slots 14 and 15 defined by closely spaced edges 14a, 14b and 15a, 15b, respectively, defining an elongated tongue 16 having an applicator head at its tip carried by yielding spring arms 16b and 16e. l

In forming the holder from the blank 10, portions 17 and 18 are bent through ninety degrees along fold lines 17a and 18a to assume the position illustrated in Figures 2 to 6, inclusive, and thus become the side plates of the tape holder. In ordenthat the side plates v17 and 18 may be secured effectively in this folded position, they are folded back along lines 17b, 18b and pro vide end plate elements 19 and 20, respectively. These end plate elements 19 and 20 overlap and preferably are shaped as shown in Figure 3, and are suitably secured to- Y gether as by a crimping operation.'

To facilitate releasably holding a roll of tape material 34 between the side plates 17 and 18 of the holder flanges 22 and 23 are folded inwardly at lines 22a and 23a to enter the hollow core of the roll, as illustrated in Figures 5 and 6. Also, in order to relieve the sharpness of the edges 11b, 12b, these edges may be flanged inwardly as indicated at 11c and 12a` of Figure 4.

Coming now to the tape positioning and snubbing'struc ture of this invention, the left-hand end portion of the blank 10 of Figure 1 forms side linger plates 24 and 25, the entire end portion being folded back along the fold line 13. In order that the applicator and cutting head presently to be described may be inserted through the snubber element, the blank is cut transversely to form slot 26 defined by closely spaced edges 26a, 26b and lonfor the cutter head presently to be described.

gitudinally to form slots 27 and 28. Additional transverse short cuts 29 and 30 are provided to form ears 31 and 32, which are folded back along fold lines 31a and 32a, as illustrated in Figures 2 and 5, thus to provide a sufficiently large aperture to receive the 'applicator and snubber head.

As will be seen from Figures l, 2, and 5, the cuts 26, 27 and 28 form a tab 33 which is bent outwardly along the fold line 33a to serve as a cradle orback-up member In shaping the snubber element the side finger plates 24` and 25 are bent along fold lines 24a and 25a and, in order that the snubber element may flare outwardly to facilitate the application of finger pressure downwardly as viewed `in Figurey 6, the blank is folded along diverging lines 24b and 25h. The snubber head is secured in the desired assembled position by inserting the corners 24e, 25e into slots 17e, 18C, respectively, and upsetting them on the fold lines 24d, 25d, as illustrated in Figures 2 and 5.

In order that the improved applicator and cutter head may be formed in accordance with this invention, `the tongue is folded outwardly along the 'fold'line 16d and again along the lines 16e. These folds form the two spring arms 16e and 16b, respectively. In effecting the last named folds, the applicator head 16a is inserted through the aperture 3312 formed by folding out the tab 33, and caused to assume the position illustrated in Figures 2 and 5. The final form of the applicator head is effected by folding the tongue outwardly along the aligned transverse fold line 16j, inwardly along fold line 16g, and again inwardly along the aligned fold lines 16t, 16u. When the applicator head 16a is inserted into the aperture 331) as described, the shoulder 16k formed by folds 16)c and 16g lodges behind snubber edge 26a so that the extended surface of applicator head 16a projects beyond snubber edge 26a, which will engage the tape as illustrated in Figure 5, to force the adhesive side thereof against the snubber edge 26a and thus prevent the return of the end` of the tape toward the roll.

The cutting mechanism is formed directly upon the applicator head 16a by cutting the blank longitudinally along lines 16m, 16:1 and transversely at 160 to form edges 16p 16g, and 16l. To facilitate the cutting operation the edge 16q is serrated in accordance with known procedures, and the tab 1161,4 formed by the cuts 16m,v 16n and 16o is bent back along the fold line 16s to serve as a brace, as shown in Figures 2, 5, and 6. The head 16a is folded along the. fold line 16v to form a flange 16W against which the edge 16p of the brace tab 16r rests. It will also be; seen that the. portions of the, applicator headin the. regions of the, aligned fold lines 16t and 16uv serve as projections that prevent theV cuttingedge 16g from contacting the at surface upon which the tape is applied.

In operation, a. roll of tape 34. is insertedA into the holder by spreading the side platesv 17 and 1S and slipping the core over the flanges 22 and. 23, as shown in Figures 5. I

and 6. The end 35 is then peeled o and threaded through the aperture 33h between the snubbing edge 26a and the shoulder 16k of theV snubber arrn 1615. In its free position the snubber arm 16b. forces the, end of the tape outwardly and downwardly (as shown in Figure 5,) to prevent the adhesive surface of the' tape from being exposed to random surfaces.

When the tape is to be applied to a desired surface, the side finger plates 24 and 25 may be grasped between the thumb and second finger with the roll 34 and holder generally located within the palm of the hand and with the forenger against the upset edges 11C, 12C. By moving the tape end- 35 against a desired surface 36 (Figure 6) and exerting sucient pressure, the, applicator surface of extension 16k causes the tape to be adhered to the surface 36. After a desired length of tape has been so adhered, the tape may be severed by turning the holder counter-clockwise, as viewed in Figure 6, until the cutting edge 16q engages the tape, whereupon the tape is cut upon application of continued pressure. By providing the cutter 16q on the movable applicator 16 instead of on the relatively stationary portion 33, much less movementl is required to sever the tape.

From the foregoing it will be seen that a tape holder, dispenser and applicator have been providedv of improved form and of such structure that they may be formed by simple operations out of a blank with no wastage of material. Moreover, the structure is such as to maintain the free end of the tape in an unexposed position thus avoiding contaminating it and preventing its engagement with. random surfaces. The structure is such as to maintain an effective snubbing action against accidental return of the free end of the tape to the roll and, in addition, the cutting mechanism is so formed that it may be brought into operation effectivelyand with facility.

If desired, surfaces of the device over which the nonadhesive side of the tape slides may be treated with a release or antifriction agent to facilitate they feeding of the tape from the roll as described in my co-pending application Serial No. 297,459.

While the invention has been described with specific reference to the accompanying drawings, it is not to be limited save as defined in the: appended claims.

I claim:
