Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention provides an adhesive tape roll made by winding a single-sided adhesive tape or a double-sided adhesive tape around a core, and a hand-held device in which this adhesive tape roll is set. This relates to the holder.

(Prior Art and its Problems) A conventional adhesive tape roll has an adhesive tape wound around a perfectly circular core made of a hard paper tube or a hard plastic tube. Therefore, the holder used to set the adhesive tape roll is
Since it has a shape with a tape roll case part that has a larger diameter than the tape roll, it can be used as a handheld holder, and is practical as a small holder that can hold adhesive tape rolls with small diameters and short tape lengths. It was nothing more than a transformation. Therefore, a holder that can be used hand-held in which a roll of adhesive tape with a sufficiently long tape length can be set has not been put into practical use for commercial use.

(Means for Solving the Problems) The present invention provides an adhesive tape roll and holder that can solve the above-mentioned conventional problems. Instead of a core, it consists of a combination of an adhesive tape roll in which adhesive tape is wound around a flexible endless core that can be rotated like a caterpillar, and a holder that can be held by hand.The holder has a tape attached to one end in the length direction. It is configured in an elongated shape with a drawer opening, and inside thereof, a pair of tape roll holding rollers for rotatably holding the adhesive tape roll in a flat oval shape in a caterpillar shape are installed near both ends in the length direction. In addition, a tape pressing roller partially protruding from the opening is provided.

(Example) An example of the present invention will be described below based on the attached illustrative drawings.

In FIG. 1, reference numeral 1 is a flexible endless winding core made of thin, flexible natural or synthetic paper made of soft plastic stick, etc., and can be rotated in a caterpillar shape. Reference numeral 2 denotes an adhesive tape of a required length that is wound on the core 1 so that the adhesive surface 2a is on the inside.

Adhesive tape roll 3 configured as above
By inserting one finger (index finger) of each hand into the core 1, the core 1 (tape roll 3) can be deformed into an oval shape as shown in FIG. By rotating the two fingers in the same direction, the core 1 (tape roll 3) can be rotated while maintaining its oval shape. In other words, the core 1 is flexible enough to allow the tape roll 3 itself to rotate in a caterpillar manner, and the thickness of the wound layer of the adhesive tape 2 is taken into consideration.

A tape roll holder for hand-held use in which the adhesive tape roll 3 having such characteristics is set will be explained based on FIGS. 2 and 3.

This tape roll holder 4 has an elongated shape that is thick enough to be held with one hand, and inside the case body 4a are tape roll holding rollers 5 that are rotatable at both ends in the length direction.
a, 5b are pivotally supported, and a tape pressing roller 7 is placed near an opening 6 formed at one end in the length direction.
However, a portion thereof is pivotally supported so as to protrude outward from the opening 6. 8 is a tape cutter constructed by bending a band-shaped spring steel plate,
a cutter portion 9 having a tape breaking edge 9a at the free end;
The cutter part 9 consists of a pressing operation part 10 connected at a substantially right angle to the cutter part 9, and a fixing locking part 11 connected to the pressing operation part 10. The fixing locking portion 11 slidably passes through a cutter guide groove 12 provided in the case body 4a so that the cutter can move in and out at a position close to the tape pressing roller 7.
is locked to the case body 4a.

Each of the rollers 5a, 5b, and 7 has a cantilevered support shaft 1 that is integrally fixed and protruded from the case body 4a.
A cover plate 4b is rotatably supported by each of 3a to 13c, and can be opened and closed with respect to the case body 4a.
A protrusion 15 is protrudingly provided on each of the support shafts 13a to 13c to support the free ends of the support shafts 13a to 13c by fitting into recesses 14 provided at the free ends of the support shafts 13a to 13c when the shafts are closed.

When setting the adhesive tape roll 3 in the tape roll holder 4, open the cover plate 4b to open one side of the case body 4a, and insert the adhesive tape that has been deformed into an oval shape using the method described above. Roll 3 is held by tape roll holding rollers 5a, 5
Fit it onto b. Then, the adhesive tape 2 pulled out from the tape roll 3 in the vicinity of the opening 6 is passed through the outside of the tape presser roller 7 (the side opposite to the side where the tape cutter 8 is located) and pulled out outward from the opening 6. Close the lid plate 4b.

In the holder 4 in which the adhesive tape roll 3 is set as described above, the adhesive surface 2a of the adhesive tape 2 pulled out from the opening 6 is placed on the tape pressing roller 7.
in a state where it is pressed against the surface to be applied 16 by,
By moving the adhesive tape 2 in the direction of the arrow in FIG. 2, the adhesive tape 2 is automatically pulled out from the tape roll 3 and applied to the surface 16 to be applied. At this time, the adhesive tape roll 3 rotates in a caterpillar manner around the pair of tape roll holding rollers 5a and 5b.

Once the required length has been pasted, push down the pressing operation part 10 of the tape cutter 8 against elasticity to lower the cutter part 9 and cut the tape torn edge 9a at its tip.
is pressed against the adhesive tape 2 at a position close to the tape pressing roller 7, and then pull up the holder 4 to remove the adhesive tape 2 from the tape broken edge 9a.
You can break it with

FIG. 4 shows a modification of the winding core. This winding core 1 is an endless caterpillar-shaped winding core made of plastic in which thin hinge parts 17 parallel to the width direction are formed at equal intervals in the circumferential direction.
Even if the hard thick part 18 is provided between the hinge parts 17, it is sufficient if the whole can be rotated in a caterpillar shape.

FIG. 5 shows an adhesive tape roll 19 in which adhesive tape 2 is wound around a core 1 so that the adhesive surface is on the outside.
The tape roll holder 20 has a structure in which the tape pressing roller 7 is omitted so that the tape roll holder 20 can be used as the tape roll holder 20. In this holder 20, a part of the tape roll holding roller 5a protrudes from the opening 6, and this roller 5a also serves as a tape pressing roller.

Incidentally, as the adhesive tape 2, a double-sided adhesive tape can also be used. Furthermore, the tape cutter 8 attached to the holder is not an essential condition of the present invention;
It is also possible to omit it.

(Operations and Effects of the Invention) The adhesive tape roll and holder of the present invention can be implemented as described above, and the adhesive tape roll is placed in a flat oval shape by a pair of tape roll holding rollers in the holder. By fitting it and using it as in the embodiment, it is possible to efficiently affix the adhesive tape of the adhesive tape roll to the surface to which it is to be applied by moving the holder by hand over the surface to be affixed.

Furthermore, since the holder is elongated, it can be held in one hand and used in the same way as a cutter knife. Even if the holder is configured to be elongated in this way, the adhesive tape roll used is also rotated in a caterpillar manner within the elongated space within the holder, so the adhesive tape roll must be wrapped with a sufficient length of adhesive tape. It can be kept running, and can be fully utilized for business purposes.
