Description

The present invention relates to a method for opening and closing a cover of a cleaning tool with a cover, and a cleaning tool with a cover, in which a pressure-sensitive adhesive roller is exposed when used so as to be able to be cleaned, and when not in use, the pressure-sensitive adhesive roller is covered and used as a protective cover for the pressure-sensitive adhesive roller. The present invention relates to a method for opening and closing a cover of a cleaning tool with a cover and a cleaning tool with a cover.

As shown in the following Patent Documents 1 to 3, an adhesive roller-type cleaning tool has been conventionally used, and various types of adhesive roller-type cleaning tools with a cover are present. Among these, Patent Document 1
Discloses a cleaning tool having an integrated semi-cylindrical cover slidable along the longitudinal direction of the handle, and the semi-cylindrical cover is slidably held between a roller covering position and an exposed position. It is configured. In addition, these two positions are fixed by fastening screws.
Further, Patent Document 2 discloses a cleaning tool provided with a cover configured by connecting two wing-plate-shaped cover pieces in a rotatable state by hinge means. In this cleaning tool, the two cover pieces are turned to the roller side by the biasing force of the spring to cover the roller, and the used state where the roller is flipped up to the opposite side of the roller to expose the roller. ,

However, when an integrated half-cylindrical cover as shown in Patent Literatures 1 and 3 is adopted, the half-cylindrical cover becomes an obstacle when the half-cylindrical cover is pulled up above the handle during use. There was a problem that the adhesive roller became difficult to see.
Further, as shown in Patent Document 1, a structure in which the position is switched between use and non-use by fastening screws is cumbersome to operate and has a problem in terms of usability.

On the other hand, when a flip-up type cover as shown in Patent Literature 2 is employed, the visibility of the adhesive roller during use is good, but the cover piece pivots greatly between use and non-use. The operability is poor because it must be done, and there is no fixing means etc. in the flipped position during use, so if carelessly touching the cover piece or hitting the cover piece during use, There is a possibility that the cover piece may return to the side of the adhesive roller due to the urging force of the spring, and there is also a problem in terms of safety.

Further, the structure in which the switching of the three positions is performed by the pushing operation of the elastically supported engaging projections as in Patent Document 3 is excellent in operability because the positions can be switched by a relatively simple operation. Two operations, that is, a pressing operation of the convex portion and a sliding operation along the handle of the semi-cylindrical cover, have to be performed, leaving room for further improvement in operability.
Further, in Patent Document 3, when the semi-cylindrical cover is fixed at the intermediate position, the used adhesive sheet wound around the adhesive roller can be cut off by pressing against the edge of the semi-cylindrical cover. . However, as the roll diameter of the pressure-sensitive adhesive sheet wound on the pressure-sensitive adhesive roller gradually decreases, the distance between the semi-cylindrical cover and the pressure-sensitive adhesive sheet wound in a roll shape gradually increases. Accordingly, when the roll diameter of the pressure-sensitive adhesive sheet is reduced as the use proceeds, there may be cases where the pressure-sensitive adhesive sheet cannot be cut well.

The present invention has been made based on such a point, and an object thereof is to easily switch between use and non-use with a single operation, and to improve the visibility of the adhesive roller during use.
