Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to a toilet seat sheet that is detachably attached to the upper surface of a toilet seat that is opened and closed in a Western-style toilet.
[0002]
[Prior art]
In this type of toilet seat, it is assumed that the seat body is composed of a pair of left and right (a set of two sheets) formed in a substantially half-moon shape that is long and symmetrical in the front-rear direction so that the seat body substantially follows the planar shape of the toilet seat. In addition, it is widely known that the sheet main body is composed of a surface base fabric having a good touch and an adhesive layer laminated on the back surface thereof, and is detachable from the toilet seat via the adhesive layer. For example, it can be seen in Japanese Utility Model Laid-Open No. 2-19298.
[0003]
Furthermore, according to the knowledge of the present inventor, a toilet seat sheet in which a number of longitudinal grooves along the longitudinal direction of the adhesive layer are provided in the adhesive layer has already been sold (document unknown). In this type of toilet seat sheet, adhesive is applied to the surface fabric of the surface base fabric. At the time of coating, a large number of grooves are continuously placed in the longitudinal direction of the original fabric with a scraper. The material is scraped off in a streak form to reduce the material cost by reducing the amount of expensive adhesive used. When the toilet seat sheet is die-cut from the original sheet after coating into the above shape, the longitudinal grooves appear in the pressure-sensitive adhesive layer of the product.
[0004]
[Problems to be solved by the invention]
Since the toilet seat sheet is easily soiled by sucking sweat on the surface base fabric that is in direct contact with the skin, it is desired that the toilet seat sheet can be used repeatedly after washing. Therefore, the pressure-sensitive adhesive layer of the toilet seat sheet is required to have a degree of adhesiveness that does not shift or fall off during use. On the other hand, it is required that it can be easily peeled off from the toilet seat when changing during washing.
[0005]
It is not easy to meet this contradictory demand. In winter, if the toilet seat is left standing for a long time, the toilet seat sheet can easily fall off. On the other hand, in the summer, if the toilet seat with the toilet lid is closed for a long time with the toilet seat closed, or if it is pressed strongly by the human body during use, the adhesive layer will be too strongly adhered to the upper surface of the toilet seat and the toilet seat sheet will be removed. When it does so, it tends to invite a situation where the adhesive sticks to the toilet seat side. For this reason, the actual situation is that the material of the pressure-sensitive adhesive layer has been difficult. Still, when the toilet seat was easily peeled off from the toilet seat, the toilet seat was easy to come off unintentionally if the toilet seat was left standing for a long time in the winter with the above-mentioned vertical groove.
[0006]
However, the present inventor originally intended that the groove is for reducing the adhesive material, but if the traveling direction of the groove is changed, even if the adhesive layer is made of the same material, the toilet seat sheet is prevented from coming off from the toilet seat. As a result of trial manufacture and experimentation of whether it is possible, the evaluation was obtained as expected, and thus the present invention was proposed. In other words, the purpose of the present invention is to improve the way of inserting the groove so that the adhesive layer can be easily peeled off without sticking to the toilet seat in the summer and inadvertently moves or falls off on the toilet seat in the winter. To provide a toilet seat.
[0007]
[Means for Solving the Problems]
In the toilet seat sheet that is detachably attached to the upper surface of the toilet seat 1 of a Western-style toilet as shown in FIG. 3, the left and right sides that are long in the front-rear direction so as to substantially follow the planar shape of the toilet seat 1 as shown in FIGS. The sheet body 2 includes a pair of left and right sheet bodies 2 formed in a symmetric, substantially half-moon shape, and the sheet body 2 includes a surface base fabric 3 and an adhesive layer 4 formed on the back surface of the surface base fabric 3. A large number of lateral grooves 5 that are substantially orthogonal to the longitudinal direction of the front and rear are provided on the outer surface of 4.
[0008]
[Action]
When the toilet seat S is used, the sheet main body 2 is attached to the upper surface of the toilet seat 1 through the adhesive layer 4. The large number of lateral grooves 5 placed in the pressure-sensitive adhesive layer 4 serve to reduce the material used for the pressure-sensitive adhesive during production and to impart appropriate cushioning properties to the entire sheet. When the toilet seat 1 is erected while the toilet seat 1 is mounted on the toilet seat 1, the upper and lower edges of each lateral groove 5 are perpendicular to the vertical direction. The toilet seat S does not come off accidentally.
[0009]
【The invention's effect】
Thus, even if the toilet seat 1 is left standing in the winter for a long time due to the presence of the lateral groove 5, the entire toilet seat sheet S is difficult to come off unintentionally, so that the adhesive layer 4 is more adhesive than necessary. There is no need to make it. Therefore, even if a person sits down in the summer, for example, when the toilet seat sheet S is strongly pressed against the toilet seat 1, the adhesive layer 4 is strongly adhered on the toilet seat 1, and the adhesive sticks when peeled off. Will not occur.
[0010]
【Example】
(First embodiment)
1 to 3 show a first embodiment of a toilet seat S according to the present invention. FIG. 3 illustrates a use state in which the proposed toilet seat S is mounted on the upper surface of the U-shaped toilet seat 1. In the toilet seat S, a pair of left and right (a set of two sheets) seat bodies 2 formed symmetrically is mounted on the toilet seat 1.
[0011]
As shown in FIG. 1, the sheet body 2 has a substantially half-moon shape that is long in the front and rear so as to substantially follow the shape of the upper surface of the toilet seat 1. 4 are integrally laminated. The pressure-sensitive adhesive layer 4 is formed by applying an acrylic or polyurethane pressure-sensitive adhesive containing a foaming agent to the surface base fabric 3.
[0012]
As shown in FIGS. 1 and 2, the adhesive layer 4 has a large number of lateral grooves 5 arranged in parallel at equal pitches across the front and rear so as to be perpendicular to the virtual axis L along the longitudinal direction of the front and rear. . The virtual axis L here means the central axis in the front-rear direction of the toilet seat 1. Specifically, the adhesive is continuously applied to the surface of the raw fabric of the surface base fabric 3, and at the time of coating, a parallel groove is made with a scraper, the adhesive is scraped off at the groove portion, and the adhesive is heated and dried. Layer 4 is formed. Next, the sheet body 2 is formed by punching the sheet body 2 from the original sheet into the shape described above in a state where the longitudinal direction of the sheet body 2 is perpendicular to the parallel grooves. Thereby, the parallel groove becomes the lateral groove 5. The lateral groove 5 has a groove width b of 0.5 to 4 mm and an inter-groove distance c of 10 to 45 mm. Here, if the inter-groove distance c exceeds 45 mm, the effect of reducing the amount of material used does not appear, and if it is less than 10 mm, there is a problem in adhesiveness, and it is more preferably 15 to 40 mm.
[0013]
(Second embodiment)
FIG. 4 shows a second embodiment of the toilet seat S according to the present invention. In this case, the transverse groove 5 is skewed at a predetermined angle θ which is not 90 ° with respect to the virtual axis L in the front-rear direction. . Thus, the lateral groove 5 may not be accurately orthogonal to the virtual axis L.
[0014]
In addition, the toilet seat 1 which the toilet seat sheet | seat of this invention makes object is not restricted to the above-mentioned U shape, As shown to (a) * (b) of FIG . Flutes perpendicular to the transverse groove 5 may be added. Further, in the illustrated example, the lateral groove 5 is linear, but it only has to extend as a whole in a lateral direction substantially orthogonal to the longitudinal direction of the front and rear, for example, a zigzag shape like a sawtooth shape, a sine curve shape, It may be a curved shape (arc shape) or a rectangular wave shape.
