Description

  The present invention relates to a cleaning article that is mounted on a holder or is used by being held by hand, and more particularly, to a cleaning article that is detachably equipped with a liquid holder impregnated with a liquid.

  As a cleaning article for cleaning a floor surface in a house, there is an article formed of a non-woven fabric and attached to a holder. This type of conventional cleaning article is generally used in a dry state, and holds and removes dust between fibers appearing on the cleaning surface of the cleaning article, or is applied to the cleaning surface. An oil agent that adsorbs dust is common. However, the cleaning article used in the dry state has a limit in removing dirt stuck to the floor surface even though it can remove dust and the like.

  Therefore, the following Patent Document 1 discloses an invention relating to a cleaning article intended to be used by impregnating a liquid.

This cleaning article has an outer layer appearing on each of the cleaning surface and the mounting surface to the holder, and an inner layer sandwiched between both outer layers, and the inner layer is made of a hydrophilic fiber such as rayon or cotton and has a predetermined shape. It is formed in thickness. Then, the dirt is easily removed by impregnating the inner layer with a cleaning agent containing a surfactant, an alkali agent, a thickener, a disinfectant and the like together with moisture.
Japanese Patent No. 3349125

  However, when the conventional cleaning article is used for a long time in a state in which the cleaning agent is impregnated in the inner layer, the moisture of the cleaning agent evaporates. As described above, when the cleaning agent impregnated in the inner layer contains a surfactant, an alkali agent, a thickener, a bactericide, etc., when the moisture of the cleaning agent is dried, It accumulates in the inner layer and the inner layer becomes stiff. Therefore, even if a new cleaning agent is injected into the inner layer later, the effective cleaning effect cannot be exhibited because the softness of the cleaning article is impaired. Accordingly, the cleaning article impregnated with the cleaning agent cannot be used for a long period of time, and needs to be discarded and replaced with a new one for each short-term use.

  In addition, it is complicated to inject a new cleaning agent into the inner layer after a certain period of use, and it is difficult to supply this cleaning agent in an appropriate amount to the inner layer, and cleaning is always performed in a good condition. I can't.

  Further, if the inner layer of the cleaning article is impregnated with only water, it can be used repeatedly by injecting new water when the water is dried. However, it is not possible to effectively remove dirt such as a floor surface simply by impregnating with water.

  The present invention solves the above-mentioned conventional problems, and provides a cleaning article that can always be impregnated with a liquid in a proper state for cleaning, enhances the cleaning effect and can be used for a long period of time. It is an object.

The present invention provides a cleaning article having a cleaning surface for cleaning a portion to be cleaned and a gripping surface opposite to the cleaning surface,
A liquid-permeable surface sheet that appears on the cleaning surface and a base material sheet that faces the grip surface, and a storage space formed between the surface sheet and the base material sheet is impregnated with liquid. The liquid holding body thus made can be attached and detached.

  The cleaning article can be cleaned in a dry state in which the liquid holding body is not mounted, or can be cleaned by mounting the liquid holding body. The liquid holding body can be impregnated with various chemical liquids such as a cleaning agent and a polishing agent depending on the intended use. When the liquid holding body is mounted and cleaned, the liquid impregnated in the liquid holding body wets the top sheet, and is further given to a portion to be cleaned such as a floor surface. When the liquid in the liquid holding body runs out or when the moisture dries, it can always be cleaned in an optimal condition by replacing and mounting a new liquid holding body.

  The cleaning article can be used with the gripping surface mounted on a mop-shaped holder, or in the case of being thick and small, the gripping surface can be held by hand for cleaning. .

  The present invention can be configured such that a part of the base sheet extends to both sides of the storage space and serves as an attachment portion to the holder.

  In the present invention, a mounting opening communicating with the storage space is formed between the edge of the topsheet and the edge of the base sheet, and the liquid holding body is stored in the storage from the mounting opening. It can be inserted into the space. Alternatively, at least a part of the top sheet is separable from the base sheet, and the liquid holding body can be mounted in the storage space in a state where the top sheet is separated.

  The liquid holder used in the cleaning article of the present invention is in the form of a sheet or plate having a back surface directed to the base sheet and a surface directed to the top sheet, and the liquid holder is hydrophilic. It is preferable to have a liquid-impregnated layer and a reinforcing layer.

  Those having the reinforcing layer have high rigidity, and are therefore easily inserted into the storage space from the mounting opening.

  For example, the reinforcing layer is provided on the back surface. Alternatively, the reinforcing layer may be liquid permeable and located inside the liquid impregnated layer.

  In the present invention, the liquid holding body impregnated with the liquid is mounted in the storage space and can be exchanged as necessary, so that cleaning can always be performed in an optimum wet state.
