ADHESIVE TAPE DISPENSER Filed Aug. 14, 1957 United States Patent() M Filed Aug. 14, 1957, Ser. No. 678,241 8 Claims. (Cl. 225--26) This invention relates to improvements in devices for dispensing adhesive tape in any desired length when peeled or stripped from a roll of such material rotatably mounted in such devices, having particular reference to the inclusion of baille means, underlying the stripped but unsevered portion of the tape to prevent said tape portion from readhering itself to the roll, and the provision of such a device and means is a principal object of the invention.

Such tapes and devices therefor have considerable utility and are disclosed, for example, in such patents as Nos. 1,760,820, 2,177,627, Reissue No. 23,129 and No. 2,275,408, as well as others. The inventions of these patents have met with considerable commercial success and are readily available for purchase in various forms inthe open market, and have been for a considerable period of time. However, during all this time one serious drawback or disadvantage has been prevalent and presented a problem heretofore not properly solved, that is notoriously well known, namely, the lack of suitable bathe means that prevents the unsevered stripped portion of the tape from re-adhering to the roll. When this occurs, it is, to say the least, frustrating and exasperating to the user to pry the same loose, more often than not, with a considerable degree of mutilation because of the excellent, tenacious, adhesive characteristics of the tape.

It long has been felt that to overcome this disadvantage would definitely provide a distinct improvement, and this now has been accomplished by means of the present invention.

Generally, while it is an object to provide a solution to the above problem, it is also an object to provide such a device that will accomplish this new result in such a manner and by such means that are inexpensive, positive in action and will tend appreciably to enhance the utility and appearance thereof.

More specically, it is an object of the invention to provide a blank of sheet metal formed into a central front wall portion, and oppositely disposed side wall portions adapted rotatably to mount a roll of adhesive tape therebetween in spaced relation to the front wall portion, the latter having an outwardly struck and upwardly raised member terminating in a cutting edge for severing and holding the cut edge of the tape and the unsevered, stripped portion extending therefrom to the roll, and baffle means extending from the front Wall between the side walls to a point adjacent the roll to underlie the unsevered portion and to block or guard. against it re-adhering to the roll portion from when it has been stripped.

Another specific object is to provide baffle means including a plate rearwardly extending from a point closely adjacent the cutting edge to a point closely adjacent the roll to underlie the unsevered portion of the tape, the plate being of a length substantially equal to the distance between the cutting edge and the roll.

Another specific object is the provision of such a plate Y lying in a plane substantially perpendicular to the axis of the roll and having an extension on the inner end thereof projecting upwardly therefrom and generally following the contour of the roll, the extension preferably terminating in a rounded edge portion traversed by the under side of the tape.

A further specific object of the invention is the provision of such a baiiie plate that is constricted along opposite edges whereby to expose the underlying marginal edges of Patented June 6, 1,961

lCC

2 the tape in order that the same readily can be grasped and lifted when caught by the plate.

It is also a specific object to provide the side walls, adjacent such a plate, with inwardly contoured depressions with the edge portions thereof substantially conforming in `coniguration to the constricted edges of the plate in order more readily to facilitate grasping the free edges of the overlying tape.

Other objects of the invention will in part be obvious and will in part appear hereinafter.

The invention accordingly comprises an article of manufacture possessing the features, properties, and the relation of elements which will be exemplied in the article hereinafter described and the scope of the application of which will be indicated in the claims.

For a fuller understanding of the nature and objects of the invention reference should be had to the following description taken in connection with the accompanying drawings, in which:

FIG. 1 is a plan View of a blank of such a device embodied by the invention;

FIG. 2 is a top view of the blank of FIG. 1 shaped into an operable device;

FIG. 3 is a side elevation of FIG. 2;

FIG. 4 is a front elevation of FIG. 2;

FIG. 5 is a perspective view of FIGS. 2, 3 and 4; and

FIG. 6 is a fragmentary portion of a slightly modified form of a downwardly pitched tape severing edge.

Referring now more particularly to the invention, there is shown generally at 10, FIG. l, a piece of sheet material, formed from a blank of said material, preferably made of metal, having a central front wall portion 11 and oppositely disposed

side Wall portions

12 and 13. Preferably these sections are beaded, as indicated at 14, to

present smooth edges and to reinforce the same. The

side Walls

12 and 13 are provided with openings terminating in annular iianges 15 to support the core of a roll of such tape, as indicated in the dotted line position at 16 in FIG. 3, after the side Walls have been bent at right angles to the front wall 11 and in spaced parallel relation with respect to each other, as shown in FIGS. 2 through 5 of the drawing.

The front Wall 11 is provided with a centrally outwardly struck member, or tongue element, indicated generally at 17 that is raised and folded upwardly along the dotted line 18 to a vertical position as shown at 19, whereupon it is again bent along dotted line 20 to provide a narrow, outwardly projecting ledge 21 that may extend at right angles to the panel portion 19 or be pitched downwardly as at 21 in FIG. 6. The

ledge

21 or 21 terminates in a cutting edge that is preferably serrated as shown at 22.

Upwardly extending from the central wall portion are be means indicated generally at 23. Such baille means preferably include a plate, or tongue element, 24 which,

of tape 16. This extension 27 terminates in a beadoroverlapped portion 28 presenting a rounded edge 29 over which the tape may pass.

It will be observed that the opposite edges of the plate portion 24 are constricted as at 30 and 31 so that the plate is appreciably narrower in this area than the width of the tape so that the latter readily can be grasped in the event the unsevered portion 25 of the tape becomes disengaged from the

cutting edge

21 or 21 because it,

will have tended to adhere to the plate portion 24, or the extension y27, or the overlapped portion 28-or all three portions. By such bale means the unsevered portion of the tape is substantially completely prevented from re-adhering itself tenaciously to the roll portion from which it has been stripped or peeled.

, In order to facilitate or enchance the ready removal of the tape when the same adheres to the bale means, and particularly to the plate portion 24, portions of the side walls f12' and 13, adjacent the plate 24, are contoured inwardly thereof to provide depressions 32 and 3 3 whose edge portions conform in configuration to the

constricted edges

30 and 31, whereby the tape readily can be grasped at its free edges overlying such constricted edges and depressions.

It is understood, of course, that in conventional devices of this type heretofore in use without the bale means of the present invention, the severed edge of the tape, with subsequent careful handling, may remain adhered along the ledge 21 adjacent the severing edge 22; but to depend upon this makes the device quite unreliable in this respect. Often enough, the tape breaks, or is severed or otherwise improperly handled by the user with a suddenness that causes the unsevered portion thereof to spring back or in some other manner to re-adhere to the roll; or the device may be thrown into a drawer, or on a shelf, where, in some manner the unsevered portion is easily disturbed to re-adhere to the roll. In any event, Whatever the manner in which such re-adherence occurs, almost all users have had, or sooner or later will encoun-A ter, such a disadvantageous situation, when it becomes almost impossible easily and readily to free the re-adhering end of the tape from the roll, without some mutilation, or without the aid of some sharp instrument, and the disadvantages are particularly obnoxious in those emergencies where the tape must be applied most hurriedly.

Such exasperating experiences are overcome by the bae member of the present invention against which, indeed, the stripped, unsevered portion of the tape can rst intentionally be made to adhere by pressing that portion of the tape against the baie. Regardless, however, of how such undesirable re-adherence might otherwise occur, it is now prevented by the bathe means of the present invention. VIt will also be understood that the bafde means has equal facility and utility whether or not the severing edge 22 is placed at the extreme end of a horizontal portion 21, a downwardly directed part 21', or whether the

portions

21 and 21 are eliminated entirely, so that a cutting means appears at a vertical or upward edge, for example, along a line extending as a vertical projection of the portion 19.

Since certain changes may be made in the above article and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall Vbe interpreted as illustrative and not in a limiting sense.

It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
