Abstract

PURPOSE: To prevent a tape from sticking to the inside of a device and being easily severed by providing a main body part with a transverse slit penetrating the free end of the tape, and providing the main body part with an apron part laid under the free end of the tape and securing the free end of the tape after the tape has been cut. CONSTITUTION: First a free end 17 of a tape roll 18 is drawn out therefrom, passed above a slit 16, and laid above an apron part 19. In this case, a dispenser is located on the tape roll 18, and its four rims 11-14 are bent twice. Second, when the tape roll 18 is drawn out by the required length, the dispenser is moved backward along the tape roll 18 until a portion called 'captive end' of the required length of the tape approaches a sawtoothed blade part 15. Then the required length of the tape is severed and a new free end 17 is drawn out from the apron part 19.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to tape dispensers, and more particularly to tape dispensers that are flexible, relatively inexpensive, simple to manufacture, and lightweight. Concerning a highly improved tape dispenser.

(Prior art) Tapes, such as so-called "adhesive tapes" for packaging, package sealing tapes, mask tapes, industrial gauge tapes, etc., are produced by winding tapes with a width of 361 cm and a length of about 50 m into a roll. Some of these tapes are transparent, some are translucent, and some are non-transparent.

Current dispensers for these types of tapes are heavy, cast metal devices that are generally designed to sit on a desk, table top, or work bench. The tape to be used is mounted in this device on a rotatable mandrel, and the free end of the tape is pulled over the ``apron'' and over the serrated blade so that it can be cut by pulling the tape down over the serrated blade. It has become.

In addition to its considerable weight, a dispenser device as described above is bulky, making it completely impractical for it to be easily carried by one person when mobility is required.

Although hand-held devices exist, they are extremely complex and have an unnecessary amount of moving parts. The tape often sticks to the inside of the device and breaks easily. Also, the device must be disassembled to remove the tape.

SUMMARY OF THE INVENTION It is therefore an object of the invention to overcome or at least minimize the above-mentioned and other disadvantages by providing a dispenser according to the invention. At a minimum, the present invention provides an alternative to previously known methods.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a main body portion that can lie above a part of the outermost turn of a roll of adhesive tape; a side portion depending from the side and a lower portion capable of overlying a portion of the exposed surface of the core member of the tape roll, the body portion having a cutting blade at one end for cutting the tape; an apron part is provided in the body part, the transverse slit passing through the free end of the tape, the apron part being able to lie under the free end of the tape and secure the free end after cutting of the tape; It is provided in the section. A tape dispenser is provided.

Preferably, when the tape dispenser is used in the first conventional mode, said apron portion is located adjacent to said cutting blade to provide a surface for holding the free end of the tape after it has been cut; The sticky side of the tape is oriented in use opposite the cutting edge and apron portion.

Alternatively, when the dispenser is used in a second non-conventional reverse mode, the apron portion is positioned behind the slit to provide a surface for attaching the free end of the tape after it has been cut and The adhesive side of the tape is oriented away from the cutting blade during use, but is oriented such that it can abut the apron portion after the tape has been cut.

(Embodiment) FIGS. 1 to 3 show a dispenser according to a first embodiment of the present invention. As can be seen from FIG. 1, this dispenser is made of sheet material and may be disposable. is advantageously stamped from a suitable sheet, such as aluminum.

The dispenser according to this embodiment has one body part 1
0 and four rims 11.1 extending in pairs from each side of the body portion 10 and forming at least partially lateral portions.
2.13 and 14. At what may be considered the front end of the dispenser, a serrated blade portion 15 is provided for cutting the tape in the usual manner. Further, a horizontal slit 16 is provided near the other end so that the tape roll 11 shown at 18 can be passed through it. The body part 10 constitutes an apron part 19 which can lie beneath the free end of the tape 17 between the sawing blade part 15 and the transverse slit 16. The serrated portion 15 is curved upwardly along the fold line 20 and is suitable for cutting the tape as it is pulled laterally and downwardly over the teeth. The apron portion 19 is folded along fold lines 21, 22 and 23 and is
The ridge on the back side of the trough abuts the outermost winding portion of the tape.

The rims 11-14 are first bent downwardly to form the side portions as shown in FIG. As can be seen, the tape roll 18 comprises a lower portion overlying a portion of the exposed surface of the core 24 of the tape roll 18. In this way,
The tape roll 18 is held between the rims 11-14 and the ridges on the back side of the apron portion 19.

The operation of the tape dispenser of the present invention is as follows.

First, the free end 17 of the tape roll 18 is pulled out and passed upwardly through the slit 16 so that it lies on the upper side of the apron section 19. The dispenser is now on tape roll 18 and its 4aI rims 11-14
is bent twice as shown in FIG. The tape roll 18 is withdrawn for the required length, at which point the dispenser is inserted into the tape roll 18 until the so-called "captive end" of the required length of tape is proximate to the serrated portion 15. be moved backwards along the

This required length of tape is then cut.

The new free end 17 is now ready to be retained and pulled out of the apron section 19 for the next use.

In other words, whereas prior art dispensers are substantially stationary and the tape roll itself rotates as the tape is dispensed from the tape roll, according to this embodiment of the invention, the tape roll is held in the hand and is virtually fixed.

The dispenser itself is movable along the periphery of the tape roll. It is also clear that the dispenser according to the invention has no moving parts.

Needless to say, as the tape is successively drawn from the roll, the diameter of the roll gradually decreases from the diameter of the first roll until it approaches the diameter of the core or cardboard core 24. To constantly compensate, the rim of the dispenser is malleable so that it can be folded and refolded multiple times to accommodate reductions in roll diameter.

The dispenser according to this embodiment of the invention is inexpensive enough to be disposable after use for a single tape roll, but if handled carefully, one dispenser can be used for several tape rolls. is also possible.

Figures 4 and 5 show a highly preferred embodiment, ideally made by injection molding from a suitable plastic material. The dispenser according to this embodiment has a main body portion 30, side portions 31 and 32. Lower portion 33, cutting edge portion 34.
Lateral slit 35. and cutting edge portion 34 and slit 3
It consists of an apron part 36 formed between 5 and 5. In particular, FIG. 5 shows how the dispenser is configured so that it can be attached to a roll of tape (not shown). One lateral part 32 of the dispenser is provided with an integrally formed thin hinge element 37 and the other lateral part 31
includes an integrally formed hook-shaped beveled edge 38 and a cooperating groove 3 that is "snap" engaged to the bevelled edge 38.
9 is provided. It will be appreciated that the formation of the hinge elements, beveled edges and cooperating grooves may vary, or the dispenser may simply be wedged into a tape roll and held by friction.

In the illustrated variation, spring means may be incorporated to 'take up the slack' that occurs as the thickness of the tape decreases during use; this variation is generally necessary for packaging tapes, etc. However, depending on the ratio of tape thickness to roll diameter, it may be advantageous in some cases.

6 and 7 illustrate another embodiment of the tape dispenser in a reverse mode different from the conventional example. The illustrated dispenser is a modification of the dispenser shown in FIGS. 4 and 5. The same reference numerals are used to refer to the same parts. Additionally, an apron portion 40 is provided behind the one-way slit 35.

In reverse mode, the free end of the tape (not shown)
is pulled through the slit 35. Conventionally, the tape is oriented so that its sticky side is on the downside, so that it can abut the apron portion 36 and/or the cutting edge 34. However, in this embodiment, the tape is inverted so that its adhesive side is above or opposite to the apron section 36 and the cutting edge 34, but when pulled toward the second apron section 40, this 2
It is on the lower side with respect to the apron part 40 of , and can come into contact with the apron part 40 after cutting.

FIG. 7 illustrates another mode of using this embodiment of the invention, namely the reverse mode. In this so-called "reverse mode" the cutting edge is above the tape being drawn from the roll. , the required length of tape is cut by twisting the wrist downwards in direction A. It is clear that in this case the dispenser itself rather than the tape roll is held. The problem with this reverse mode is that Since the tape is cut from its non-adhesive side, the problem of how to hold the cut end of the tape is solved by the provision of the second apron section 40. In this way, it is also observed that this dispenser can be used with one hand. This embodiment (illustrated in FIG. 6)
However, it is also possible to use it in a conventional mode as if it were the dispenser shown in FIGS. 4 and 5.

As an aid while using this dispenser, there is a second
In embodiments of the present invention, a guard (not shown) depending from the rear of the apron may be used, and the guard may extend completely around the roll of tape and wrap around the entire roll.

Another way to overcome the problems described above when using any dispenser according to the invention in reverse mode is to provide an array of spikes or pins 41 to penetrate the tape and hold it there after cutting, as shown in FIG. It is configured to hold the free end 17 in place. The main advantage of using this reverse mode is that the use of the tape in so-called packaging begins by ``slapping down'' or slapping the end of the tape onto, for example, a carton 42 (Figure 7). In other words, there is always an exposed portion of the adhesive side of the tape that must be "slapped down" onto any article to which it is applied.

If spike 41 is not provided, in this mode the point 4
Additional friction on the tape may be required at point 3 (Figure 8).

The dispenser of the present invention includes, for example, FIGS. 9 and 1.
It should be understood that various changes can be made to the shape, as illustrated in the inverted view in FIG.

Figure 11 shows what is called a ``double dispenser'' which is applicable to both of the two modes described above. Figure 12 is an isometric view of a further embodiment. is particularly intended for use with thick, high-duty tapes requiring extremely sharp cutting edges, and includes a pair of integrally molded laterally disposed guards or shoulders 44. .

The dispenser of the invention may be made of metal, as shown in FIGS. 1-3, or may be made of injection molded plastic, or alternatively may be made of a combination of different materials, such as plastic and metal cutting edges. It will be obvious to the reader that it may be made of any suitable material or combination thereof.

The shape, thickness, coarseness or fineness of the teeth, etc. of the cutting or serration blade may be any suitable, and in fact,
In a very simple embodiment as shown in the figures, a single cutting edge or spike may be provided, as indicated by the reference numeral 45.

Furthermore, it is advantageous to provide one or more partitions along the tape path to facilitate the use of the dispenser for 1IliT different tapes. These partitions may be in the form of longitudinal ribs.

As described above, those skilled in the art will readily understand that various changes and modifications may be made to the present invention without departing from the spirit and scope of the invention.
