Persons acquainted with the old and well known art of securing packages by means of pressure sensitive adhesive tape are aware that many such dispensers have been developed and are in use. However, existing dispensers for multiple rolls of adhesive tape are either too expensive, too complicated to use, difficult to reload, bulky, unsightly or, for one or more other reasons, not completely satisfactory. Thus, the need still exists for an improved multiple roll tape dispenser which avoids all of the foregoing problems or limitations.

Especially just prior to holidays, it is desirable to have rolls of several different types of adhesive tape readily available for packaging operations. Yet, it is frequently undesirable to have a dispenser of such multiple rolls available at all other times of the year. Thus, the need has long existed for an inexpensive, efficient and easily operated multiple roll tape dispenser which can be readily and quickly put into operation without involving a substantial investment of time or expense.

A further object of this invention is the provision of a multiple roll tape dispenser, as aforesaid, which is readily and easily adaptable to handle rolls of adhesive tape having varying widths and diameters.

Other objects and purposes of this invention will become apparent to persons familiar with this type of equipment upon reading the following descriptivematerial and examining the accompanying drawings in which:

FIG. 1 is a perspective view of a dispenser embodying the invention and in its normal operating position,

FIG. 2 is a rear-end elevational view of said dispenser, and

FIG. 3 is a sectional view taken along the line IIIIII in FIG. 2.

For convenience in description, the terms upper", lower", front", rear and words of similar import will have reference to a dispenser as appearing in FIG. 2, which is a rear view thereof. The words inner, outer and derivatives thereof, will have reference to the geometric center of said dispenser and parts thereof.

SUMMARY OF THE INVENTION The objects and purposes of the invention, including those set forth above, have been met by providing a multiple roll dispenser having a base frame including a mounting plate, an integral upright flange at the front end of the mounting plate, and a pair of parallel support plates secured to the mounting plate and extending upwardly therefrom remote from and perpendicular to the upright flange. A cutting edge member is secured to the upper end of the upright flange and a cylindrical roll support is removably mounted upon the upper edges of the parallel plates. Interlock means is provided between the plates and cylinder for preventing relative movement towards and away from the cutting edge member. The'adhesive tape rolls are mounted upon the cylinder between the mounting plates.

DETAILED DESCRIPTION The tape dispenser 10, for removing strips of tape 11 from the rolls 12 is comprised of a substantially L- shaped base 13 which is preferably, but not necessarily, fabricated from sheet material, such as sheet metal. The base 13 has a mounting plate 14 and an upright front flange 16, the upper edge portion 17 of which is bent horizontally so that it is substantially parallel with the mounting plate 14 and extends in the same direc tion from the front flange 16.

An elongated cutting element 18, having a lengthwise cutting or serrated edge 19, is rigidly secured to the upper end of the front flange 16 by a clamp member 22 which is mounted on the front flange 16 by screws 23. The cutting edge 19 of element 18 projects slightly above the upper edge portion 17 so that the new outer end portion of the tape 11 can adhere to and be held in place by the upper edge portion 17 after a tape cutting operation has been performed.

The clamp member 22 has upwardly projecting,

integral ears

26 and 27 which guard the opposite, otherwise dangerous, ends of the cutting edge 19 on the element 18.

A channel-shaped support member 28 has a web 29 which is secured to the mounting plate 14, as by welding, and a pair of parallel

upright flange plates

32 and 33 which are both preferably perpendicular to the front flange 16. The support member 28 is preferably adjacent the rear end of the mounting plate 14.

The

upper edges

36 and 37 of the

flange plates

32 and 33 preferably define a plane which slopes downwardly and rearwardly, in a direction away from the front flange 16. However, under some circumstances, it may be advisable to have this plane parallel with the mounting plate 4 or even sloping downwardly and frontwardly.

A hollow cylindrical roll holder 38 is somewhat longer axially than the distance between the remote sides of the

flange plates

32 and 33. Said roll holder may be fabricated from metal, plastic, rigid pressed materials or the like, and it has a pair of

slots

41 and 42 near the opposite ends thereof which open in the same radial direction. The slots preferably define planes substantially perpendicular to the central axis of the cylindrical roll holder and they are located so that the upper edge portions of the

flange plates

32 and 33 are slideably, but preferably snugly, receivable into the slots 41 and 4.2, respectively. As illustrated in FIG. 3, the

slots

41 and 42 preferably diametrically extend approximately half way through the roll holder 38.

It will be apparent that holders 38 of various diameters may be furnished with a given base 13 to accommodate tape rolls of different diameters. Moreover, a single holder 38 may have two or more sections of different diameters.

The

upper edges

36 and 37 of the

flange plates

32 and 33, respectively, have recesses or

grooves

43 and 44, respectively, which open upwardly near the rear ward ends of said edges. The

grooves

43 and 44 are slightly wider than the thickness of the material in the roll holder 38 so that portions of said roll holder adjacent the rearward ends of the

slots

41 and 42 can be received downwardly into said

grooves

43 and 44, respectively. This interlock positively opposes relative movement between the

flange plates

32 and 33 and the roll holder 38.

The mounting plate 14 may be provided with openings 46 for securing said dispenser upon a surface, such as a counter (not shown), by means of conventional screw means, not shown.

OPERATION Although the operation of the above-described dispenser will be apparent to persons skilled in the art following a reading of such description, the operation will be briefly summarized hereinafter for convenience.

While the dispenser it) can be operated without being anchored upon the upper surface of a table or counter, as by hand-holding the dispenser in position upon said surfaces, it is at least desirable to anchor said dispenser by means of screws inserted through the openings 46 in the mounting plate 14. One or more rolls 12 of adhesive tape are sleeved upon the cylindrical roll holder 38 after which the roll holder is placed on the

flange plates

32 and 33 so that the upper end portions thereof are snugly received into the

slots

41 and 42. Portions of the cylinder at the ends of such slots are slidably received into the

grooves

43 and 44. The free end of the tape 11 on each of the rolls 12 is then loosened and pulled away from the roll and, if desired, the free end is adhered to the upper surface of the upper edge portion 17 by pressure so that the tape is readily available for manual grasping and use.

When it becomes desirable to remove a piece of tape 11 from one of the rolls 12, the said tape is grasped between the upper edge portion 17 and the roll 12 and raised upwardly so that it can be moved forwardly of the cutting edge 19 a distance necessary to provide the desired length of tape to be detached from the roll. The hand grasping the tape is then moved downwardly so that the tape comes into engagement with the cutting edge 19 after which the piece of tape is severed from the remainder of the tape on the roll in the usual manner.

The upper edge 17 cf the front flange iGis loii ateEl so that the new free end of the tape will normally be pressed against such edge portion during the cutting operation and, accordingly, will remain in that position after the cutting operation is performed where it can again be easily grasped.

when it becomes desirable to replace or change a roll of tape, it is necessary only to raise the roll holder 38, remove one of the rolls and replace it with another. The roll holder is then placed back onto the

flange plates

32 and 33, as described above.

Alternatively, relative horizontal movement between said roll holder and the

plates

32, 33 can be effected by disposing one of the

slots

41, 42 and its

corresponding plate

32, 33 at an angle to the other slot and plate, such angle being around a vertical axis. Thus, the roll holder would be wedged against movement toward and away from the cutting element 18.

Although a particular preferred embodiment of the invention has been disclosed in detail for illustrative purposes, it will be recognized that variations or modifications of the disclosed apparatus, including the rearrangement of parts, lie within the scope of the present invention.
