Definitions

  • the present invention relates to a scouring member highly capable of removing stubborn grease or stains without scratching the object to be cleaned.
  • the types of grease or stains, the way in which the grease or stain is stuck to the surface, and the ease of removability is also variable depending on the unique properties of each of the diverse types of materials. Additionally, there are various levels of scratchability. Particularly, when grease or a stain with a relatively high hardness is adhered to a utensil or the like that has a relatively low hardness, it is difficult to remove that grease or stain without scratching the utensil.
  • IH (Induction Heating) cooking devices have rapidly become popularized.
  • Top plates of these devices are generally made from glass raw materials, but stains that adhere to such are frequently grease and stains. It is difficult to remove such grease or stains without damaging the glass raw material of the top plate. Additionally, there is a trend to use the same glass raw material used in IH cooking devices in gas stoves as well, so the same problem exists here.
  • Japanese Unexamined Patent Application Publication No. 2003-225187 describes a moist cleaning sheet including a substrate sheet capable of holding a liquid that is impregnated with an aqueous detergent, wherein at least one surface of the substrate sheet includes a liquid-permeable fiber mass, and scouring particles having a Mohs hardness of 5 or less are retained in the fiber that forms the fiber mass.
  • Japanese Unexamined Patent Application Publication No. 2001-327429 describes a bathtub cleaning tool including a pouch filled with charcoal particles having a diameter of from 0.9 mm to 5.5 mm on one side or both sides of a sponge-like plate-like core material.
  • the charcoal particles can alternate the pouch filled with the charcoal particles and a cloth covering this pouch as desired.
  • the disclosed scouring member is highly capable of removing stubborn grease or stains that does not easily scratch surfaces to be cleaned that are formed from materials having relatively low hardness.
  • the scouring member is capable of removing stubborn grease or stains without the use of a detergent.
  • the scouring member is capable of removing stubborn grease or stains without scratching a top plate of an IH cooking device or a gas stove made from glass raw materials, and without the use of a detergent.
  • the disclosed scouring member includings a substrate layer and a scouring coating layer that is disposed at least on part of the substrate layer and includes a binder and powdered activated carbon.
  • a scouring member can be provided that can remove stubborn grease and stains from surfaces to be cleaned made from materials having a Mohs hardness greater than powdered activated carbon, particularly, from ceramics, glass, hollows, and the like; and that does not easily scratch the surface of the object to be cleaned.

Even if the powdered activated carbon is embedded in the binder, the raw material is adjusted so that a thickness of the binder is as thin as possible, and thereby the hardness of the scouring coating layer becomes controlled by the hardness of the powdered activated carbon.

  • Figure 4 shows a scouring member 4 having a substrate layer 40 that includes a first surface 42 and a second surface 44 opposed to the first surface 42, wherein a scouring coating layer 46 is provided partially on each of the first surface 42 and two sides adjacent thereto.
  • the scouring member 4 can be obtained, for example, by forming the scouring coating layer 46 on unmasked parts by spray coating a slurry including a liquid binder and powdered activated carbon on the partially masked first surface 42 of the substrate layer 40, then cutting the substrate layer 40 into a desired product shape as necessary, and thereafter, using the same mask, spray coating the same slurry onto a part of each of the two sides adjacent to the scouring coating layer 46 of the first surface 42.

  • the single particle 72 of the powdered activated carbon is shown partially uncovered from the binder 70. At least a part of all of the powdered activated carbon 72 included in the scouring coating layer is partially uncovered from the binder 70. Therefore, it is not necessary to use detergent because the adsorption action of the powdered activated carbon itself is manifested and grease and stains can be absorbed.
  • the powdered activated carbon 72 is not limited to being partially uncovered from the binder 70 in an initial state, and, for example, may become uncovered from the binder 70 during use of the scouring member. However, because the powdered activated carbon 72 is a fine powder, compared to particulate activated carbon and the like, it is less prone to become dislodged from the binder 70.
