Description

  The present invention relates to an adhesive cleaner that removes dirt and the like adhering to a display screen of a small portable device such as a smartphone, and more specifically, an adhesive type convenient for carrying that can easily remove dirt on a display screen. Regarding cleaners.

  In recent years, small portable devices such as smartphones and tablet portable terminal devices such as notebook personal computers are rapidly spreading. However, these devices are provided with display screens such as liquid crystal panels and organic EL panels.

  In particular, recently, a touch panel type display unit that combines the function of the input unit as well as the display unit has been adopted, so the display screen is likely to get oily dirt such as user's hand dirt and sebum, Oily dirt is more noticeable than dirt such as dust.

  A piece of paper such as a general cloth piece or tissue paper may be used to remove the dirt adhering to the display screen. However, it is difficult to wipe off the oily dirt completely with a general cloth piece. In addition, it is difficult not only to remove dirt with a piece of paper such as tissue paper, but also the dropped fibers may remain on the display screen.

  For this reason, cleaners made of ultrafine fibers such as wiping cloth made of ultrafine fibers and woven cloth made of ultrafine synthetic fibers and natural fibers have been proposed as dedicated cleaners for removing stains on the display screen. .

  In addition, as described in Patent Document 1 below, a fiber cloth having a cleaning surface that wipes off the dirt on the display screen can be attached to and detached from a mobile phone via a pressure-sensitive adhesive layer provided on the back side of the fiber cloth. A cleaner that can be carried with a mobile phone has also been proposed.

  However, when using the above-mentioned fiber cleaner to wipe off dirt adhering to the display screen, especially oily dirt such as hand stains and sebum, if the fiber cleaner is pressed firmly against the display surface, the fibers will not slip. There was a problem that the finger that was holding down slipped and the display screen could not be wiped as expected.

  Also, even if you try to wipe off the oily stains on the display screen using a fiber cleaner as described above, it will simply stretch the sebum stains on the display screen, and even if you wipe it multiple times, the sebum dirt will be completely removed. There was also a problem that it did not fall.

  In addition, since the fiber cleaners described above are made of woven fabric, they are not only more expensive than non-woven fabrics and paper, but they also accumulate oily stains when used continuously, so they must be cleaned regularly. There was also the problem of having to do it.

  And in the cleaner like the said patent document 1, although it was made to be able to carry to a mobile phone so that attachment or detachment was possible via a pressure sensitive adhesive, when the adhesive strength of a pressure sensitive adhesive became weak, adhesive force was shown. The work of recovery (wiping with a damp cloth, washing away dirt) is troublesome. In addition, there is a problem that the mobile phone is dropped and lost without noticing that the adhesive strength is weak.

  Then, this invention is providing the adhesive type cleaner which can remove the dirt adhering to the display screen of small portable apparatuses, such as a smart phone, reliably and easily, and is lightweight and convenient to carry.
