Description

[Detailed Description of the Invention] The present invention relates to an improvement of an adhesive type cleaner.

As an adhesive cleaner, a roll of adhesive tape is attached to a roll with a handle, and when the adhesive strength of the adhesive surface decreases due to adhesion of dust, the adhesive tape roll is unwound one turn to reveal a new adhesive surface. There are well-known methods of emitting it.

In this type of conventional adhesive cleaner,
If the tape support of the adhesive tape is hard, and therefore the adhesive tape winding body is also hard, and there are recesses on the surface to be cleaned,
It is difficult to bring the adhesive surface into contact with the concave surface, making complete cleaning difficult.

In addition, since the adhesive tape winding body is hard, the impact that the winding body receives when the surface to be cleaned is uneven,
Alternatively, the winding body receives a strong impact the moment the cleaner contacts the floor surface, and dust tends to fly up, which poses a problem for cleaning rooms in semiconductor and precision equipment manufacturing industries.

An object of the present invention is to provide a roll adhesive cleaner that can be cleaned even on uneven surfaces by reliably preventing dust from flying up, and which is easy to handle.

The adhesive type cleaner according to the present invention is a cleaner in which an adhesive tape roll is mounted on a roll, and is characterized in that the adhesive tape is a laminate tape of a nonwoven fabric and a polyethylene film, with an adhesive layer provided on the nonwoven fabric surface. The configuration is as follows.

The present invention will be explained below with reference to the drawings.

FIG. 1A is a perspective view showing an adhesive type cleaner according to the present invention, and FIG. 1B is an explanatory cross-sectional view taken along line bb in FIG. 1A.

In FIGS. 1A and 1B, 1 is a roll, which is rotatably supported on a horizontal shaft 2 having an arm 21. In FIG. 22 is a handle. 3 is an adhesive tape winding body, in which a single-sided adhesive tape having a non-adhesive portion 31 on one side is wound on a winding core 32 with the adhesive side facing outside. 33 is a perforation provided in the adhesive tape wound body 3. 4 is a tape cover;
A release treatment layer 41 is provided on the inner surface.

As shown in FIG. 2, the above-mentioned adhesive tape is made of a thick nonwoven fabric a, such as a rayon fiber nonwoven fabric, with an adhesive layer b provided on the upper surface, and a thin polyethylene film C laminated on the lower surface. The nonwoven fabric a may also be embossed.

As the cleaner is used, the adhesive strength of the adhesive surface decreases due to the adhesion of dirt and dust. When the usage limit is reached, it is necessary to unwind just one roll of the adhesive tape to reveal a new adhesive surface. In this case, the greater the force (peel force) required to peel off the back side of the adhesive tape layer to be unwound from the surface (adhesive layer) of the underlying tape, the greater the tape tension required for unwinding. The strength of the adhesive tape must be set to withstand this tape tension.

If the peeling force is S, then the tape tension T required for unwinding can be expressed as T=KS (K is a constant).

In addition, the thickness of the nonwoven fabric a is ta, and the Young's modulus is
If the thickness of the Ea polyethylene film C is tc and the Young's modulus is Ec, then the tension that is shared by the nonwoven fabric a out of the above-mentioned unwinding tension T is the tension Ta of the polyethylene film C
The tension Tc shared by Ta=T/1+taEa/tcEc=KS/1+taEa/tcEc − Tc=KS/1+taEa/tcEc − Since Ec is much larger than Ea, most of the above unwinding tension is polyethylene film C
The tension Tc acting on the polyethylene film C is given by the second equation above.

However, since polyethylene has weak polarity and weak adhesive properties, the above peeling force S is small, and therefore the unwinding tension given by the above two equations is
Tc becomes small, and by simply applying a small tension to the polyethylene film C, it becomes possible to unwind the adhesive tape described above.

Therefore, the thickness of the polyethylene film C can be reduced, and with the same outer diameter of the adhesive tape wound body, the thickness of the nonwoven fabric can be increased by the amount that the thickness of the polyethylene film can be reduced. The cushioning properties of the wound body as a whole can be effectively improved.

In the cleaner of the present invention, the above-mentioned peeling force S is reduced by using a material with weak adhesive properties for the supporting tape, and as in the case of a peel-treated supporting tape (coated with a release agent), the peeling force S is reduced. There is no problem when the release agent migrates to the adhesive layer, and therefore, the above-mentioned low release force S can be maintained stably over a long period of time, such as when stored in a cleaner. However, even when the thickness of the nonwoven fabric is increased, smooth unwinding of the adhesive tape can be guaranteed for a long period of time.

As mentioned above, in the adhesive type cleaner according to the present invention, the thickness of the nonwoven fabric can be made sufficiently thick, and the ratio of the nonwoven fabric to the entire adhesive tape winding body can be increased accordingly. Because of its excellent conformability to uneven surfaces, it can be reliably cleaned even on uneven surfaces, and because of its excellent shock absorption effect, it can effectively prevent dust from flying up. Furthermore, unwinding can be easily performed due to the polyethylene film functioning as a tension member.
