Description

  The present invention relates to a sponge holder that improves the grip and workability of a sponge.

  Conventionally, in order to wash off dirt and oil film stuck to the surface of tableware, etc., remove the sponge that can be washed off softly and efficiently using flexibility, food waste and oil cake stuck to the surface of tableware. A double-layer sponge with woven felt fibers or nylon fibers on one side was used.

  However, the flexible sponge and the two-layer sponge in the above cannot easily remove food residue and dirt stuck to the surface of the tableware, and the contact surface is highly rigid to wash them off. The only way to rub it off was to use a tortoise lion and metal wool scrubber made of material.

  In order to solve the above-mentioned problems in the related art, a proposal has been made in which a part of a flexible sponge has rigidity. For example, a long band part and a hook hole part connected to the base end of the band part are provided, and the band part includes an arbitrary part that bisects the band part along its longitudinal direction. A “washer binding band” (see Patent Document 1) in which a slit having a length, a width, and a shape is cut and formed has been proposed.

  However, the proposal of a binding band for a cleaning device is to bind a cleaning device having flexibility such as a sponge to give rigidity, but in order to attach the band part to the sponge, the thickness width of the sponge exceeds a certain value. The sponge itself tends to be thicker and larger than the commonly used sponges, and the flexibility of the sponge itself when trying to remove dirt locally. There was a problem that could not be dropped.

  Further, a structure “cleaning sponge and cleaning tool” in which a notch is provided in the sponge and a plate piece provided at the tip of the handle is forcibly inserted into the notch of the sponge and the sponge and the handle are integrally assembled (see Patent Document 2) ) Has been proposed. Easy and reliable cleaning of bathrooms, washrooms, kitchens, etc.

  However, the proposal of the cleaning sponge and the cleaning tool has a problem in durability due to changes over time because the contact fixing area between the sponge and the plate piece is extremely small, and has a long handle. However, it was not limited to a kitchen sponge, but mainly limited to cleaning tools such as flooring and wall surfaces.

  In addition, two or more arms project from a base member that is sucked and supported on the wall of the kitchen sink by a suction cup. The arms can be used to deform and sandwich deformable dishwashing tools such as sponge scrubbers. There has been proposed a “washing tool holder” (see Patent Document 3) that is provided with a space that can be used.

  However, the proposal of the washing tool holder is formed for the purpose of holding the sponge on a wall surface or the like, and cannot be used as a sponge in various applications while being sandwiched between the washing tool holders.

  In order to solve the problems related to the conventional sponge as described above, the present applicant pays attention to the inherent flexibility and ease of processing of the sponge, and uses appropriate flexibility and rigidity according to the situation of the washing work. Therefore, under the idea that the gripping and workability of the sponge itself cannot be improved, the amount of deformation of the sponge can be reduced by piercing the sponge from above with a plurality of protruding protrusions provided below the base. We developed a sponge holder that can improve the grip and workability of the sponge by minimizing it, and also make the sponge have both flexibility and rigidity, leading to the proposal of the “sponge holder” of the present invention. is there.
