Since such a conventional holder for toilet paper has a structure that is difficult to operate with one hand, there is a problem that it is extremely inconvenient for a person who cannot use both hands due to hemiplegia or injury.

Therefore, Patent Document 1 describes a cutting tool for toilet paper that allows the toilet paper to be cut with one hand. As shown in FIG. 13 , the toilet paper cutting tool is provided from a mounting base 101 that can be attached to the upper surface of the front portion of the upper cover 15 of the toilet paper holder 1 and each end of the mounting base 101. It includes a pair of arm portions 102 and 103, and a cut body 104 swingably bridged between the arm portions 102 and 103. A cutting blade (without numbering) is formed on the front edge of the cutting body 104. "

This toilet paper cutting tool is configured so that the cut body 104 forms a peripherally closed opening 105 for pulling out the toilet paper P, while forming a downward open passage for facilitating pulling out the toilet paper P. ing. The peripherally closed opening 105 is formed by placing the free end portion 104a of the cut body 104 on the upper surface of one arm portion 102 and taking a horizontal posture. The lower open passage is formed by taking the free end portion 104a of the cut body 104 in an inclined posture or an upright posture with the base end portion 104b of the cut body 104 as a fulcrum.

This toilet paper cutting tool must be reset immediately after the toilet paper P is first set in the toilet paper holder 1, or the tip of the toilet paper P must be wound up under the upper cover 15 and set again. When it was no longer possible, the cut body 104 was placed in an inclined posture or an upright posture to form a downward open passage, and then the cut body 104 was placed in a horizontal posture to form a peripheral closed opening 105. By setting the condition, the tip of the toilet paper P can be pulled out from the opening 105.

Then, the tip of the toilet paper P pulled out from the opening 105 in the horizontal direction is cut by the cutting blade of the cutting body 104 by applying a downward tension with one hand. The end portion of the toilet paper P on the uncut side remains on the upper surface of the cut body 104. By picking the tip of the remaining toilet paper P, the toilet paper P can be subsequently pulled out.

As a result, as shown in FIG. 3A, the holding member 52 hangs down below the cutting tool main body 51 to form an opening 59 with the cutting tool main body 51, and FIG. 3 (b). ), It is possible to move up and down between the cutting tool main body 51 and the holding position for holding the toilet paper P.

That is, in the open position where the string body 58 is not gripped, the holding member 52 tries to descend by its own weight and the weight 52w, but is designated as the cutting tool main body 51 by the string body 58 provided with the short string body 57 and the stopper portion 58d. Keep it suspended at intervals. At the holding position where the string body 58 is pulled upward, the holding member 52 rises and is magnetically attracted to the lower surface of the cutting tool main body 51.

Next, a method of attaching the toilet paper cutting tool 5 will be described. First, as shown in FIG. 4, the base sheet 50 is attached to the upper cover 15 of the toilet paper holder 1. Then, as shown in FIG. 5, the cutting tool main body 51 is attached to the base sheet 50 by magnetic attraction to obtain a sheet winding body holder provided with the sheet winding body cutting tool.

Next, a method of cutting the toilet paper P using the toilet paper cutting tool 5 will be described. First, at the open position of the holding member 52 shown in FIGS. 2 (a), 3 (a) and 6 (a), the tip Pa of the toilet paper P is pulled out to a predetermined length with one hand. Since the holding member 52 is in the open position, the tip Pa of the toilet paper P can be easily extended to a predetermined length by using the distance between the cutting tool main body 51 and the holding member 52 (the opening 59 shown in FIG. 2A). Can be pulled out to.

Then, in order to set the holding member 52 as the holding position, when the string body 58 is grasped and pulled upward, the holding member 52 becomes as shown in FIGS. 2 (b), 3 (b) and 6 (b). It is lifted and magnetically attracted to the back surface of the cutting tool main body 51, and the holding member 52 and the cutting tool main body 51 sandwich the toilet paper P.

Further, at the holding position of the holding member 52, the string 58 insertion portion of the holding member 52 and the string 58 connecting portion of the cutting tool main body 51 coincide with each other, so that one side of the holding member 52 is the edge of the cutting tool main body 51. It is in a state of protruding sideways (to the left in FIG. 3B) from the portion. This protruding portion is a release portion 52c that is pushed down so as not to be magnetically attracted to the cutting tool main body 51.

When the tip Pa of the toilet paper P is pulled upward with one hand, the toilet paper P can be cut through the cutting blade 51a. That is, since the toilet paper P is sandwiched between the holding member 52 and the cutting tool main body 51, even if the cutting tool main body 51 rotates upward, it is not pulled out. As a result, the tip Pa of the toilet paper P can be reliably cut with one hand.

Next, the time of pulling out the toilet paper P after being cut will be described. Since the release portion 52c of the holding member 52 projects laterally from the edge cutting tool main body 51 at the holding position, when the release portion 52c is pressed with one hand, the holding member 52 descends against the magnetic attraction force. The holding member 52 is separated from the cutting tool main body 51 by a weak force by the weight 52w fixed to the lower surface, and descends to the open position. As a result, an opening 59 is secured between the cutting tool main body 51 and the holding member 52. The tip Pa of the toilet paper P can be freely pulled out from the opening 59 again.

When the cutting tool main body 51 is not used, as shown in FIG. 7, the cutting tool main body 51 is temporarily removed from the base sheet 50, the cutting blade 51a of the cutting tool main body 51 is directed toward the wall surface, and the holding member 52 is used. Is brought closer to the wall surface side so as to be sandwiched between the toilet paper holder 1 and the substrate 11, and is reattached to the base sheet 50. In this state, the tip edge of the upper cover 15 is exposed and can be used as a cutting blade.
