Fulcrum Tape Pinching Gun

Abstract

A tape dispensing device with a tape head pivotally mounted on a housing. The first end of the tape head features a cutting tool and the second end features one or more protrusions or feet. Adjacent to the tape head and located on an inner surface of the housing is an arc or trough shaped stop that is complementary in shape to the second end of the tape head. When the user applies force to the first end of the tape head while placing tape on a separate surface, the tape head rotates causing the foot or feet on the tape head to push the length of tape into the trough causing it to stick to the trough. At the same time, the foot creases the tape causing the free end of the tape to stiffen or stick out.

DETAILED DESCRIPTION OF THE INVENTION

[0023] FIG. 1 shows a tape head 11 featuring some of the inventive aspects of the described tape dispensing device. Specifically, the tape head 11 consists of a body 12 with a first end 13 and a second end 14. These designations are arbitrary and are merely used to discuss the ends of the tape head 11 separately. The first end 13 of the tape head 11 typically features, but is not required to feature, a cutting tool (not shown) such as a serrated blade. The body 12 of the tape head 11 also features a female connector or cavity 16 at a point between the cutting tool 15 and the second end 14 of the tape head. In addition, the tape head 11 features feet 17 at its second end 14. In this embodiment, there is a foot 17 located on either side of second end 14 of the tape head 11. Other embodiments may contain more or less feet 17. As discussed above, in some embodiments there may be a single foot 17 that traverses the entire width of the second end 14 of the tape head 11. Furthermore, the tape head can feature one or more guards 18 flanking either side of the cutting tool 15.

[0024] FIG. 2 shows the tape head 11 attached to a housing 19 of the tape dispenser 10. As discussed below, this disclosure relates to certain features that are not specific to the shape of the housing itself. There are a variety of tape dispensers on the market and this design can be adapted to virtually any of them.

[0025] FIG. 2 shows that the housing 19 can also feature a ledge 21 at a point that is below or underneath the first end 13 of the tape head 11. In preferred embodiments of the tape dispenser 10, the first end 13 of the tape head 11 is configured to engage with the ledge 21 on the tape head 11. Specifically, the ledge 21 is a flange or lip onto which a portion of the first end 13 of the tape head rests. A portion of the first end 13 of the tape head 11 also extends past the ledge 21 and housing 19 thereby causing a portion of the first end 13 of the tape head 11 to hang over the edge of the housing 19. In some embodiments, there is a second ledge, lip or flange 27 formed by the underside of the tape head 11 that is complementary to and is shaped to engage with the ledge 21 of the housing.

[0026] As shown in FIG. 2, the first end 13 of the tape head features a cutting tool 15 and the second end 14 of the tape head 11 includes one or more feet 17 that are sized, shaped and positioned to contact and fit into the trough 22 that is shown on an inner surface 20 of the housing. In preferred embodiments, the second end 14 of the of the tape head 11 features a foot 17 on either side of the tape head 11 to allow the feet 17 to contact a trough 22 on either side of the device 10. Because the tape head 11 is pivotally connected to the housing 19 and the tape (not shown) passes beneath the tape head 11 before exiting the housing 19, when the first end 13 of the tape head 11 is pivoted in a first direction, i.e. the first end 13 is lifted up and away from the housing, the second end 14 pivots around the fulcrum or pivot point (not shown) and the foot or feet 17 are inserted into the trough 22 thereby trapping a section of the tape in the trough 22.

[0027] A skilled artisan will appreciate that the arc or trough shape of the stop 22 located on the inner surface 20 of the housing 19 can be shaped a number of different ways. However, the inventor anticipates that the shape of this stop 22 allows the foot 17 to fit into it. In this embodiment, when the foot 17 presses a length of tape (not shown) into the center of the trough 22, the tape has the entire inner surface of that trough 22 to which to adhere. In addition, because the trough 22 is located underneath the second end 14 of the tape head 11, the trough 22 contacts a portion of the length of tape other than the free end of the tape. Rather, this device presses a portion of the length of tape into the trough 22 at a point closer to the roll of the tape than the free end of the tape would be. As a result, the length of tape is secured to the inner surface of the trough 22 such that it will not be easily pulled free by accident, thereby preventing the free end of the tape from contacting the roll of tape.

[0028] As previously discussed, the pinching of the tape in the trough 22 by the foot or feet 17 creates a crease in the length of tape near its free end. When the user cuts the tape, the free end of the tape is forced out or straightened by the crease. The tape is already curved or curled somewhat when it is removed from the roll thereby making it easier for it to reattach to the roll. The crease helps to interrupt or arrest the curve in the length of tape making it stick out more than it normally would without the crease.

[0029] FIG. 3 shows the housing without the tape head 11 attached. The trough 22 is still visible on the inner surface 20 of the housing 19. As discussed above, preferred embodiments have this structure on both opposing inner surfaces 20 of the housing 19. In addition, also featured on the inner surface 20 of the housing 19 is a male connection point or protrusion 24. This protrusion is the pivot point 24 around which the tape head 11 rotates. This pivot point or fulcrum 24 engages with the female connection point or cavity 16 located on the body 12 of the tape head 11. Moreover, FIG. 3 shows the support column 26 that is present on some embodiments of this device. The support column 26 is a structure that attaches to the inner surface 20 of the housing 19 underneath the stop or trough 22 and provides additional structural support to the trough 22. As above, the housing 19 features a ledge 21 which will be discussed with respect to the movement of the tape head 11 (see below).

[0030] FIGS. 4 and 5 illustrate the movement of the tape head 11. FIG. 4 shows the tape head 11 at rest. The first end 13 of the tape head 11 rests on the ledge 21 of the housing 19 when no force is applied to the tape head 11. At the same time, the second end 14 of the tape head 11, featuring the foot 17 is positioned above the stop or trough 22 when no force is applied to the tape head 11. FIG. 5 shows the tape dispenser in use. Specifically, when the user desires to apply tape to a separate surface (not shown), they pull tape 23 off of the roll and past the tape head 11 to the separate surface like a foldable cardboard box (not shown). In doing so, the tape passes between the trough 22 and the foot or feet 17 featured by the tape head 11. As illustrated in FIG. 5, when the first end 13 of the tape head 11 is pushed upward off of the ledge 21 and away from the housing 19, the second end 14 of the tape head 11 moves downward allowing the foot or feet 17 to push a length of tape 23 into or onto the surface of the trough 22. The force applied to cut the tape pushes the tape head 11 into this position allowing the foot or feet 17 to trap the portion of the length of tape 23 into the trough 22. When the tape head 11 comes to its resting position, the length of tape 23 is still attached to the trough 22, thereby preventing it from curling back onto the roll of tape. In addition, when the length of tape 23 is pushed into the trough 22, it creases the tape 23 at that point. That crease has the effect of straightening the length of tape and making it more rigid and less likely to fall back onto the roll of tape.

[0031] The figures all illustrate a single version or embodiment of the inventive tape dispensing device. These figures are only meant to illustrate certain aspects of the device and should not be interpreted to mean this device cannot be adapted to other forms of tape dispensing devices. The structures described above can be used with any tape dispensing device that has a guide on it that contacts or is otherwise located adjacent to strips of adhesive as they are pulled off of a roll.
