Description

  The present invention relates to a paper toilet seat sheet laid on a toilet seat of a Western-style toilet.

  A toilet seat sheet used on a toilet seat having a vertically long elliptical toilet seat opening and a vertically long substantially elliptical toilet seat outer edge is generally formed in a vertically long rectangular shape. This vertically long rectangular toilet seat has a wide seat surface when it is laid on the toilet seat, so it is folded in two, preferably quadruple, before being laid on the toilet seat. A large number are stacked and suspended in a take-out container attached vertically to a wall in the toilet, and are taken out one by one from a take-out port formed on the front surface of the take-out container. To make it easier to take out the toilet seat sheet one by one from the container outlet, it is folded in a vertical direction along a horizontal fold line shifted from the horizontal center line of the vertically long rectangular shape, and the shorter one folded in steps The sheet edges are arranged in front, and the shorter sheet edge faces the container outlet, and the shorter sheet edge facing the outlet is picked up so that it can be easily removed one by one. .

  In addition, a longitudinally elliptical defecation opening that fits the longitudinally elliptical toilet seat opening is formed at the center of the toilet seat having a longitudinally rectangular seat surface. This vertically long oval defecation opening is formed at the center of the vertically long rectangular toilet seat. This is because the toilet seat opening is formed at the center of the toilet seat outer edge, that is, at the center of the toilet seat. It is natural that the toilet seat sheet laid on the entire toilet seat is also provided with a defecation opening at the center position of the toilet seat, and when the toilet seat sheet is laid on the entire toilet seat, the toilet seat seat is easily aligned with the toilet seat opening. This is for a reason.

  The conventional toilet seat sheet shown in FIG. 6.1 shows the unfolded state laid on the toilet seat, and FIG. 6.2 shows the quarter-folded state before being laid on the toilet seat. In order to make it easy to take out one sheet at a time, it is folded in steps and a toilet opening is formed in the center of the toilet seat, and it has been widely used to date. In this toilet seat, the sheet folded in half with the vertical center base line X as the vertical folding line L1 is folded in half along the horizontal folding line L2 shifted in the vertical direction from the horizontal center base line Y, and is folded in four. In this case, since the folding is performed at the horizontal folding line L2 shifted from the horizontal central baseline Y, the defecation port 12 formed at the center of the toilet seat does not match as shown by the solid line and the broken line in the four-fold state. For this reason, in this toilet seat sheet, after the defecation port 12 is formed, it must be folded in steps, and the defecation port 12 cannot be punched out after being folded in steps. Therefore, in this toilet seat sheet, a large number of sheets folded in a four-folded state are stacked, and a defecation port cannot be punched and formed collectively on the stacked folded sheets.

Fig. 7.1 shows the unfolded state of the toilet seat, and Fig. 7.2 shows the toilet seat sheet folded in four before being placed on the toilet seat. In order to make it easy to take out, the sheet is folded in a stepwise manner, and a number of folded sheets that are folded in a stepwise manner are stacked, and a defecation port is punched and formed in a lump. However, since this type of toilet seat has a stool port 12 that is symmetrical with respect to a horizontal fold line L2 that is shifted in the vertical direction from the horizontal center base line Y, the stool port 12 extends in the longitudinal direction from the center position of the toilet seat. The purpose of forming the defecation opening 12 at the center of the toilet seat cannot be achieved.
