Application August 19, 1940, Serial No. 353,241
(Cl. 21S-33) 8 Claims.
My invention relates to a tape dispenser wherein the adhesive surface of the tape may be of a non-drying character or the adhesive tape may be made with a glue-like surface which when moistened may be applied to the surface to which the tape is to be adhered.
A feature of the invention resides in providing a simple construction Where the compartment for holding the adhesive may be molded from a plastic material, and where the sides fit together by telescoping the same together.
A feature resides in providing a container which may be easily opened by pressing the finger through a hole in one side wall until the finger meets a transverse wall of the other side, and by causing the nger to exert pressure against said wall, the two sides are separated so that a new roll of tape may be placed within the same.
A further feature resides in providing a projecting portion on one side of the dispenser which projecting portion may be undercut so as to leave a protruding edge over which the free edge of the adhesive tape may extend so that the same may be easily engaged when it is desired to bring the free end of the tape under the pressing roller. This may also be accomplished by a cut-away portion in the casing which leaves the free edge of the tape in position to be easily engaged.
It is also a feature to provide a soft rubber or composition pressing roller which causes the tape to be pressed onto any uneven surface.
Another feature of the invention resides in the cut-off knife which is placed ahead of the roller and which acts as a key to hold the side wall portions of the casing in line when the same is closed.
These features together with other details and objects of my invention will be more fully and clearly set forth in the following specification and claims.
In the drawing forming a part of my specication:
Figure 1 illustrates a side view of my dispenser.
Figure 2 is a side view of the dispenser with one side wall removed.
Figure 3 illustrates the inside of the side Wall which has been removed from the casing shown in Figure 2.
Figure 4 is a section on the line II-- of Figure 1.
Figure 5 illustrates a side view of the pressing roller.
Figure 6 illustrates an edge View of the pressing roller.
Figure 7 illustrates a perspective view of the key cutter.
Figure 8 illustrates a. portion of the casing, showing a hole in the side Wall which holds the free edge of the tape away from the side wall when the same is drawn back over the same.
The casing of my taper A may be made of molded plastic or any other suitable material and is composed of the side I0 and the side I I. The outline or shape of the dispenser A may be of any desired character, such as round, octagonal, or any desired outside shape or formation. I have illustrated a generally round formation to the main body portion of the casing from which projects a hood for covering the pressing roller I2.
The pressing roller may be made of rubber or other soft material, or of any material desirable, and is adapted to be supported between the side walls I0 and II in the openings I3 in the same by the shaft I4 Whichprojects from either sidev of the roller I2. The ends of the shaft I4 are preferably rounded or pointed at I5 so as to cause the same to enter the openings I3 easily. The roller I2 is held freely removable when the side walls are separated and may be readily replaced. The roller I2 may be molded with the shaft I4 formed integral with the body, if it is desired, in which case, it should be made of plastic material.
The side walls I0 and II are held together mainly by the telescoping core portions. The tubular core portion I6 is formed on the side wall I0 and projects inwardly of the same and is adapted to telescope into the tubular core portion II as illustrated in Figure 4 when the sides I0 and Il are held together. These'tubular portions are frictionally engaged with each other in a manner so as to provide suitable means for holding the side walls in closed position as illustrated in Figures 1 and 4.
The side wall III is formed with a depressed wall portion I8 against which the finger can be forced as illustrated in Figure 4, to separate the walls I0 and II. The tubular core portion Il provides a bearing for receiving a roll of adhesive tape B as illustrated in Figures 2 and 4.
When the roll of tape B is in place on the tubular portion I1, the wall I0 may be telescoped by the tubular portion IS entering the tubular portion Il to close the container A. In closing the container A the holes I3 are aligned with the ends I5 of the shaft I4 so as to hold the roller I2 in place between the walls. To further align the walls I0 and II, I provide the recesses I9 in which the key and cutter 20 is positioned. The key cutter 20 normally remains xed in the for- Ward hood end 2| of the side wall Il as illus- 'trated in Figure 2. The recess I3 formed in the wall I0, shown in Figure 3, is exactly the same as the recess I3 formed in the wall I I and when the wall portions I and I I are put together the projecting portion of the key cutter 20 is adapted to fit into the recess I9 of the wall III. The key cutter is formed with an enlarged edge 22 and an oi'i'set serrated cutting edge 23. The serrated cutting edge 23 projects beyond the surface 24 of the side wall II, whereas, the enlarged portion 22 fits into the enlarged portion I9 formed in the inner end oi' the recess I9. The key cutter 20 is held by spring tension and friction normally in the recess I9 in the portion II. Thus the key cutter 20 forms a means of aligning the walls III and II when they are put together. I also provide a recess 25 formed in the edge of the wall II as illustrated in Figure 2 and into which the projecting key portion 26 formed in the edge of the wall I0 is adapted to fit. I'he portion 26 is shown in Figure 3.
When the tape from the roll B is adapted to be used in the dispenser A, the free end 21 of the same is brought around under the pressing roller I2 as illustrated in Figures 1 and 2. To apply the tape, it is only necessary to cause the roller I2 to press down against the back of the tape and pull the dispenser along over the surface to be taped. When it is desired to out off the tape, the dispenser is tilted so that the tape 21 will come in contact with the cutting teeth ofthe cutter 23, whereupon the tape is cut off. The free end 21 of the tape can be adhered to the surface of the portion I I as illustrated in Figure 2 with the extreme free end 21' projecting beyond the raised edge 28 which is formed on the side wall portion II and is illustrated in Figures 1, 2 and 4. The raised portion 28 is under-cut so that the tape end 21 will project in a manner so that it will be easily engaged to lift it ofi" of the surface ofthe wall II and bring it under the roller I2 in position to be used.
Instead of using the raised edge 28 to provide a free engagement of the end 21 of the tape end 21, I provide in an alternative form an opening 29 in the side portion I I. This provides a means of permitting the iinger nail or giving free access to the end 21 of the tape to remove the tape from its adhered position as illustrated in Figure 8.
I provide an alternative form for my dispenser wherein a well 3 is provided in which a wick 3| may be placed which may be saturated with water and which wick presses against the roller 32. The roller 32 is placed a slight distance away from the roller I2 so that the tape 33 may be passed under the roller I2 and in a position so that it will strike the moistening roller 32. The wick 3| may be urged by a spring 34 toward the roller 32. In this form of my dispenser, a dry adhesive tape may be used with a glue surface which may be moistened as the tape is drawn from the dispenser by the roller I2.
In operation the roller I2 acts to draw the tape off of the roll B as it is desired for use, and with my dispenser the tape can be quickly attached to any surface by simply drawing the dispenser over the surface and causing the roller I2 to press the tape against the surface to be taped.
which acts a key to hold the sides'- line together, together with the means for holding the extreme free end 21 of the tape projecting be -v yond the shoulder or edge 23 or within the opening 23 so that it may be easily taken hold of to bring it under'the roller I2 when it is `desired for use. It is also a feature to provide a marginal reinforcing rib 35 formed on the sides III and I I, and inner ribs 33 formed on said sides which reinforce the side walls and provide gripping means so that the dispenser may be more Leasily held when using the same.
The case of the dispenser A may be made in a manner so that the portion of the casing which covers the roller I2 is in the form of a hood C and the side wall I0 is in the form of a disc separating from the hood C on the circular line 33, as shown in Figure 4. It is obvious, however, that the side wall III may extend over the entire side of the casing as illustrated in the inside formation of the same shown in Figure 3. When the casing is made with the wall I0 in the form of a disc, the roller I2 is held and positioned between the sides of the hood and is not ordinarily removable. The same is true of the cutter 20.
With these features I provide a device of a simple practical nature which makes it easy to assemble and disassemble and to dispense tape from the same.
