Sticky cleaner for removing organic dirt

Abstract

Provided is a sticky cleaner that can easily remove organic dirt adsorbed on a surface of an article with greater dirt-removing workability. The sticky cleaner provided by the present invention is used for removing organic dirt adsorbed on a flat surface of an article. The sticky cleaner comprises a dirt-collecting member that collects the organic dirt as it makes contact with the flat surface. In the dirt-collecting member, the part to make contact with the surface is formed with a PSA. The surface-contacting part of the dirt-collecting member exhibits an adhesive strength of less than 1 N/25 mm as a measured value based on the 180° peel test specified in JIS Z0237.

1 . A sticky cleaner used for removing organic dirt adsorbed on a surface of an article, the sticky cleaner comprising
 a dirt-collector that collects the organic dirt as the dirt-collector makes contact with the surface of the article,   the dirt-collector has a surface-contacting part to make contact with the surface of the article, the surface-contacting part being formed with a pressure-sensitive adhesive, and   the surface-contacting part of the dirt-collector exhibits an adhesive strength of less than 1 N/25 mm as a measured value based on the 180° peel test specified by JIS Z0237.   
     
     
         2 . The sticky cleaner according to  claim 1 , wherein the surface-contacting part of the dirt-collector exhibits an adhesive strength of 0.01 N/25 mm to 0.5 N/25 mm as the measured value based on the 180° peel test specified in JIS Z0237. 
     
     
         3 . The sticky cleaner according to  claim 1 , wherein the sticky cleaner comprises a cylindrical rolling member, and the dirt-collector is arranged along the lateral surface of the rolling member. 
     
     
         4 . The sticky cleaner according to  claim 3 , further comprising a grip that rotatably supports the rolling member. 
     
     
         5 . The sticky cleaner according to  claim 1 , wherein
 the dirt-collector is an adhesively single-faced pressure-sensitive adhesive sheet comprising a sheet of support substrate and a pressure-sensitive adhesive layer placed above the support substrate, and   the single-faced pressure-sensitive adhesive sheet is wound with the pressure-sensitive adhesive layer on the outside to form a pressure-sensitive adhesive sheet roll.   
     
     
         6 . The sticky cleaner according to  claim 5 , wherein the pressure-sensitive adhesive layer comprises an acrylic polymer at a ratio of 50% by mass or higher. 
     
     
         7 . The sticky cleaner according to  claim 6 , wherein the acrylic polymer is a crosslinked acrylic polymer. 
     
     
         8 . The sticky cleaner according to  claim 6 , wherein the acrylic polymer is a thermoplastic acrylic polymer. 
     
     
         9 . The sticky cleaner according to  claim 6 , wherein the pressure-sensitive adhesive layer further comprises a plasticizer. 
     
     
         10 . The sticky cleaner according to  claim 1  used for removing human sebum dirt as the organic dirt. 
     
     
         11 . The sticky cleaner according to  claim 1 , wherein the article is a portable device having a flat surface on which a glass or synthetic resin display is present.
