Description

  The present invention relates to an adhesive cleaner using an adhesive tape roll wound so that the adhesive surface of the adhesive tape faces the front side. It relates to an adhesive cleaner that can be used.

  Adhesive cleaner is an adhesive tape with a dust-removing adhesive surface formed on one side of the substrate, and extended from one end of the grip with an adhesive tape roll wound with the adhesive surface facing the front side. And a cleaning tool main body provided with a support roller rotatably supported on the shaft and rotatably supporting the adhesive tape roll.

  By the way, in this type of adhesive cleaner, when all the adhesive tapes are used, only the core core of the adhesive tape roll remains on the support roller, so that it is necessary to remove the core core.

  Therefore, in Patent Document 1, in order to remove the core core safely, a stopper made of a pair of elastic pieces is provided on one end side of the support roller, and the elastic pieces of the stopper are brought down inside each other, whereby An adhesive cleaner is disclosed in which the core core can be removed with one touch by releasing the locking of the core core.

  Incidentally, the adhesive cleaner described in Patent Document 1 is the most common type in which the core core has an inner diameter of 38 mm. In this type, since the core core has a relatively small diameter, even if the stoppers are pushed inward from each other, the knob portions come into contact with each other, so that the elastic piece of the stopper does not break.

  However, in the case of a large-sized adhesive tape roll for business use in which the inner diameter of the core core is 38 mm or more, the diameter of the support roller is similarly large. Therefore, since the distance between the elastic pieces is large, if the elastic pieces of the stopper are pulled too much inwardly, the elastic pieces may be broken from the base.

  Apart from this, the large adhesive tape roll has a large core core diameter, so when attaching the adhesive tape roll to the support roller, it is difficult to smoothly guide the end of the adhesive tape roll along the support roller. It was difficult to install with one touch.
