Further, if the lid body 23 is directly attached to the holder main body 1, a one-stage type adhesive tape holder is obtained as shown in FIGS. 4 and 5, and the present invention basically has this structure. . FIG. 6 shows a state in which the adhesive tape winding body 50 is mounted, and the same applies to the case of a multistage adhesive tape holder.

Thus, the adhesive tape holder of the present invention is
Adhesive tape roll 50 mounted on tape mounting cylinders 3 to 13
7 and FIG. 7 in order to make it possible to rotate lightly and to selectively mount the adhesive tape winding body 50 having different widths. 8
It is configured as shown in.

Hereinafter, the tape mounting cylinders 3 and 13, the engaging portion 10
And 20, the fitting tubular portions 25 and 21, and the locking portions 26 and 22 have the same shape, respectively. The collar surface 24 of the lid 23 and the middle stage holder 1
Since it has the same function as the first collar body 12, a simple configuration for fitting the lid body 23 to the holder body 1 will be described below. The same applies when the middle holder 11 is used.

The engaging portion 10 and the engaging portion 26 are formed so that they can be fitted to each other while sliding in the lateral direction. Locking part 26
Is formed on the outside of the fitting tubular portion 21 as one protrusion in the vertical direction, one protrusion in the circumferential direction, or two or three protrusions at a separated position,
The lower portion is cut as an inclined surface (tapered surface) 26a so that the upper portion of the tip portion in the fitting direction becomes the protruding end. The inclined surface 26a may be formed into a flat surface,
It is preferable to make it slightly curved and make the tip end rounded.

The engaging portion 10 is formed as a protrusion 10a having two or more steps with a gap into which the engaging portion 26 can be inserted inside the tape mounting cylinder 3, and the engaging portion 2 is circumferentially arranged.
6 is formed at one or more places so as to correspond to No. 6, and the lower portion thereof is abraded as an inclined surface 10b so that the upper portion of the tip portion in the fitting direction of each protrusion is the protruding end. The inclined surface 10b may be formed in a flat surface shape, but it is preferable that the inclined surface 10b has a slightly curved surface and the tip portion has a rounded shape. A stopper 10c is provided on the other end of each protrusion 10a so as to prevent the locking portion 26 from coming off.

Each protrusion 10a of the engaging portion 10 and the engaging portion 2
As shown in FIG. 7 (A), the positional relationship with 6 is such that the fitting cylinder portion 25 is fitted into the tape mounting cylinder 3 and the collar surface 24 formed at the upper end of the fitting cylinder portion 25 is At the position where it is in contact with the upper end of the tape mounting cylinder 3 (synonymous with the minimum width of the adhesive tape winding body 50), the locking portion 26 has the lowermost protrusion 10a of the engaging portion 10.
The height is set to be slightly higher than that of the protrusion 10a and is set so as to fit within the vertical width of the protrusion 10a.

Each protrusion 10a of the engaging portion 26 and the engaging portion 10
The upper and lower widths may be set so as to sequentially correspond to the standardized sizes of several kinds of widths of the adhesive tape winding body 50.

With the above configuration, FIG.
As shown in (B), when the lid 23 is fitted into the holder body 1 and rotated, the locking portion 26 and the tip of the engaging portion 10 abut, and the inclined surfaces 26a and 10b of both are brought into contact with each other. In conformity with this, the locking portion 26 (lid 23) rises slightly along this inclination, is inserted between the projections 10a, 10a, and both are engaged. At that time, the collar surface 24 slightly rises to form a slight gap S between the upper end of the tape mounting cylinder 3 and the gap S causes the collar surface 24 to come into contact with the side end of the mounted adhesive tape winding body 50. Since it disappears, the adhesive tape winding body 50 can be smoothly rotated.

To mount the adhesive tape winding body 50 on the tape mounting cylinder 3 of the adhesive tape holder having the above structure, the lid body 23 is used.
Rotate the tape to remove it, and attach the adhesive tape roll 5 to the tape mounting tube 3.
While fitting 0, the claw body 8 is hooked with a finger and raised outward, fitted so that the side end of the adhesive tape winding body contacts the contact surface 4, and the claw body 8 is released to separate the blade. 9 may be pressed against the adhesive tape surface and the lid 23 may be fitted again.

The adhesive tape holder 50 operates as follows. That is, by pressing the tape surface with a finger, the adhesive tape winding body 50
When is rotated, the peeling blade 9 of the claw body 8 is pressed against the surface of the adhesive tape winding body 50 and is constantly elastically pressed.
Is caught on the tape end of the adhesive tape winding body 50, and the tape end is raised. The adhesive tape can be used by peeling it by picking up the raised adhesive tape part with fingers.

A particularly preferable example of the structure of the adhesive tape winding body 50 is as follows. Adhesive tape roll 50
As shown in FIG. 9, a synthetic resin long adhesive tape 52 made of OPP or other appropriate material is wound around a winding core 51. The pressure-sensitive adhesive tape 52 is formed as a pressure-sensitive adhesive-coated surface 53 on which a pressure-sensitive adhesive is applied except for a slightly width portion on one end side of the winding body, and a pressure-sensitive adhesive-uncoated surface 54 or a release surface having a release layer on the above-mentioned some portions. The boundary 55 of both parts is continuous in the longitudinal direction. Slits (cuts) 56, which are parallel to each other in the winding direction at desired intervals and are cut in the winding direction in the radial direction, leave the end of the pressure-sensitive adhesive-uncoated surface 54 slightly, and the slits 56 are substantially formed. It is formed over the entire width. In addition, the slit 56 may be formed in the full width,
In that case, it is preferable that the end surface of the non-adhesive surface 54 is slightly adhered.

The adhesive tape winding body 50 is composed of the adhesive tape 5.
Since 2 is adhered by the adhesive in the wound state and the end of the adhesive-uncoated surface 54 is continuous in the longitudinal direction, even if the slit 56 is formed, it is in the wound state. Is maintained as it is, it does not lose its shape and part does not flicker. At the time of use, the adhesive-uncoated surface 54 portion between the adjacent slits 56, 56 is peeled off,
If this is picked up and peeled off, the unit adhesive tape 57 with one unit between the adjacent slits 56 can be peeled off.

When the adhesive tape winding body 50 is mounted on the adhesive tape holder and used, the rotation of the adhesive tape winding body 50 causes the peeling blade 9 at the tip of the claw body 8 to move, as shown in FIGS. Since the surface of the pressure-sensitive adhesive-uncoated surface 54 of the pressure-sensitive adhesive tape 52 is constantly in contact with an appropriate elastic pressure P, the peeling blade 9 is caught in the slit 56 of the pressure-sensitive adhesive tape 52 as it rotates, and the layers are separated because the pressure-sensitive adhesive is not coated. The adhesive-uncoated surface 54 easily enters the back side of the adhesive-uncoated surface 54, and as a result, the adhesive-uncoated surface 54 is lifted above the nail 8, and at the same time, the connection or the bonded portion of the end of the adhesive-uncoated surface 54 is simple. As shown in the drawing, the adhesive-uncoated surface 54 of each of the unit adhesive tapes 57 separated by each slit 56 rises independently so that it can be easily picked by a finger as shown in the drawing.

In this way, by simply turning the adhesive tape winding body 50, the adhesive-uncoated surface 5 of the plurality of unit adhesive tapes 57
Since a plurality of 4 are separated in a row and automatically stand up, the adhesive coated surface 53 is peeled off by sequentially pulling them, and a desired number of a plurality of unit adhesive tapes 57 can be obtained.

The peripheral wall 5 serves to facilitate the formation of the nail 8 and protects the adhesive-uncoated surface 54, and the high peripheral wall portion 6 is provided with the peeling blade 9 to prevent the adhesive-uncoated surface 54. Adhesive tape roll 5
It is useful to prevent 0 from rotating once and to peel off the unit adhesive tape 57 before rotating once.

It is most preferable to use the pressure-sensitive adhesive tape holder having the above structure by mounting the pressure-sensitive adhesive tape roll 50 having the above-mentioned structure, but use a pressure-sensitive adhesive tape roll having perforations instead of the slits 56. can do. In addition, a long adhesive tape winding body having no slits or perforations, or an adhesive tape winding body obtained by imparting tearing directionality to the width direction of the winding body, and further a long length having no adhesive-uncoated surface 54. Even when a lengthy adhesive tape roll is used, the tip of the tape can be peeled off by the peeling blade 9 of the nail 8.

The nails 8 to 18 may have any structure as long as the peeling blades 9 to 19 are formed so as to elastically approach the tape mounting cylinders 3 to 13. For example, the base of an independent pawl is pivotally attached to the collar body, and a spring attachment portion is formed between the pawl body and the collar body portion to interpose a spring, and the tip of the pawl body is always springed in the axial direction. It is also possible to adopt a structure in which the claw body is biased and the knob portion that can be pulled up against the spring is formed.

In order to prevent the nails 8 to 18 from being artificially pressed by an erroneous operation,
A protective wall covering the entire outside can be continuously formed from the peripheral walls 5 to 15.

[0035]

According to the present invention, the adhesive tape roll mounted can be easily rotated by a one-touch rotating operation of turning with a finger, and the necessary adhesive tape can be peeled from the wound body. An adhesive tape holder can be provided, and the holder has a very simple structure so that the mechanism is stable and easy to operate.

Particularly, if the lid body is simply fitted, the flange surface is joined to the side end of the adhesive tape winding body, and the adhesive tape winding body is sandwiched by the contact surface of the holder body and the flange surface. As a result, friction occurs, and it becomes difficult for the adhesive tape winding body to rotate smoothly. However, by fitting with a proper deviation in the detaching direction, the collar that is joined to the side edge of the adhesive tape winding body at the beginning of fitting. Since the surfaces are appropriately displaced and this mated state is maintained stably, instability of mating of the lid is eliminated,
Since the frictional contact is not hindered, the roll of the adhesive tape is kept easy to rotate, which makes it extremely easy to use.

The fitting operation of the lid is made simpler and more effective by the inclined surface formed on at least one of the engaging portion and the locking portion.
