Description

  The present invention relates to a liquid retaining tape that is applied to a corner portion between a toilet bowl installed on a floor surface of a toilet and the floor surface, a corner portion between the floor surface and a wall surface, and the like.

In a toilet where a Western-style toilet is installed, a part of men's urinals may flow down to the floor surface along the outer peripheral surface of the toilet, and condensation may flow down to the floor surface along the wall surface. The darkness is generated by repeating the adhesion of dust to the liquid flowing down on the floor surface. Since dirt on the floor surface can be reduced by laying a sheet on the floor surface, a mat laid on the floor surface is used (for example, Patent Document 1).
Registered Utility Model No. 3061557

  However, since the mat placed on the floor surface of the toilet is cut in advance, a gap is formed in the corner between the mat and the toilet and the corner between the mat and the wall surface, and dirt is accumulated in the gap. There was a problem that darkening would occur.

  The present invention has been made in view of such circumstances, and a main purpose thereof is to provide a liquid retaining tape having a groove for bending and an adhesive layer on one surface thereof, so that a mat and a toilet laid on the floor surface are provided. An object of the present invention is to provide a liquid-retaining tape that can prevent blackening from occurring in a gap in a corner even when a gap is generated in a corner between the corner and a corner between a mat and a wall surface.

  Another object is to provide a plurality of slits on each edge on both sides in the width direction, so that wrinkles are generated even in a corner between a floor surface and a Western-style toilet with a curved outer peripheral surface. Another object of the present invention is to provide a liquid retaining tape that can be applied along a curved corner.

The liquid-retaining tape according to the present invention has liquid-retaining properties, and has a groove for bending at both ends in the longitudinal direction at the middle in the width direction. The edge on one side in the width direction is the longitudinal direction. A first slit extending from the plurality of positions spaced apart to the bending groove, and the edge on the other side in the width direction includes a second slit having a different position in the longitudinal direction from the first slit. A non-slit portion is provided between the second slit and the bending groove, and an adhesive layer is provided on one surface thereof.

In the present invention, the user who has purchased the liquid-retaining tape cuts into a length corresponding to the corner in the toilet and bends it at right angles from the groove for bending. , And a corner between the floor surface and the wall surface, and by pressing one side of the width direction against the floor surface and pressing the other side of the width direction against the toilet bowl or the wall surface, Since the liquid retaining tape can be affixed , small water that flows down along the outer peripheral surface of the toilet and dew that flows down along the wall surface can be retained with the liquid retaining tape to prevent darkening at the corner.
In addition, since the width of the slit can be changed by bending the liquid retaining tape bent at right angles from the groove for bending along the curved outer peripheral surface of a toilet bowl or the like, the wrinkle is placed on the liquid retaining tape. The liquid retaining tape can be applied along a curved corner without causing it.

According to the present invention, even when a gap is generated in the corner between the mat and the toilet laid on the floor, the corner between the mat and the wall surface, etc., the liquid flowing down to the corner can be retained, It is possible to prevent darkening in the gaps at the corners. And even if it is a curved corner, this liquid retention tape can be stuck along the curved corner, without producing a wrinkle in a liquid retention tape.

  According to the second invention, even in a curved corner, the liquid retaining tape can be stuck along the curved corner without causing wrinkles in the liquid retaining tape.

  Hereinafter, the present invention will be described in detail with reference to the drawings illustrating embodiments thereof. 1 is an enlarged perspective view of one end of the liquid retaining tape, FIG. 2 is a plan view of the liquid retaining tape, FIG. 3 is a bottom perspective view of the liquid retaining tape, and FIG. 4 is an enlarged sectional view of the liquid retaining tape.

  The liquid retaining tape 1 according to the present invention is formed of a nonwoven fabric. The nonwoven fabric is processed by relatively thin-walled fibers formed by entanglement of fibers in which a first thermoplastic fiber such as polyester is mixed with a second thermoplastic fiber that melts at a lower melting point than the thermoplastic fiber. A sheet-like web is formed, the sheet webs are overlapped to form a relatively thick lap web, the lap web is made into a felt shape by a first needle punching process, and one surface of the felt web is made into a second needle. Raise by punching. The nonwoven fabric formed in this way has good liquid retention and an appropriate degree of flexibility. Further, as the first and second thermoplastic fibers, fibers having a deodorizing action against ammonia odor are used. In addition, a non-deodorant fiber may be used for these 1st and 2nd thermoplastic fibers.

  An adhesive layer 2 having adhesiveness and shape retention is applied and formed on the back surface of the nonwoven fabric thus formed, in other words, on the back surface of the liquid retaining tape 1 using the nonwoven fabric.

  The adhesive layer 2 is made of a synthetic resin material obtained by blending a filler with an emulsion of a tacky acrylate copolymer and a methyl methacrylate butadiene copolymer that is well compatible with thermoplastic fibers.

  The adhesive layer 2 is formed by the following process. A stirring chamber communicating with an air source is provided in the middle of the delivery path for sending out the solution of the synthetic resin material described above by a pump, and the solution supplied to the stirring chamber is stirred by blowing air into the stirring chamber. The solution is bubbled, the foam solution is applied from the outlet of the delivery path to the back surface of the nonwoven fabric constituting the liquid retaining tape 1, and the applied foam solution is averaged by a doctor blade, and then heated to about 120 ° C. After drying in the drying chamber for 1 to 2 minutes, after taking out from the drying chamber and cooling, the foamy solution is cured in a sticky state, and the adhesive layer 2 having a plurality of microbubbles is formed. The A part of the solution applied to the back surface of the nonwoven fabric penetrates into the nonwoven fabric.

  The second thermoplastic fiber of the nonwoven fabric is melted by drying when forming the adhesive layer 2 described above, and the first thermoplastic fiber of the nonwoven fabric can be bonded to each other by the second thermoplastic fiber, The second thermoplastic fiber and the acrylic acid ester copolymer and methyl methacrylate butadiene copolymer in the solution are chemically reacted to form a cross-linking bond between molecules, thereby increasing the bonding strength between the adhesive layer 2 and the nonwoven fabric. In addition, the shape retention of the nonwoven fabric can be improved, and wrinkles due to washing can be prevented.

  Furthermore, the above-mentioned drying causes a chemical reaction between the acrylic ester copolymer and the methyl methacrylate butadiene copolymer in the foamy solution, resulting in cross-linking between molecules, and all the foam in the solution is microscopic. It becomes a bubble. The shape retention of the adhesive layer 2 can be improved by the cross-linking of the acrylic ester copolymer and the methyl methacrylate butadiene copolymer in this solution, and the shape retention of the nonwoven fabric is further improved by the shape retention. In addition, wrinkles caused by washing can be prevented even better. Moreover, since microbubbles are also generated on the surface of the adhesive layer 2, when the adhesive layer 2 is pressed against a flat floor surface or the like, each of the plurality of microbubbles exposed on the surface discharges the internal air and performs a vacuum adsorption action. None, the vacuum adsorbing action and the adhesiveness enhance the adhesiveness of the adhesive layer 2.

The liquid retaining tape 1 is formed by cutting the nonwoven fabric on which the adhesive layer 2 is formed as described above into a tape shape. The liquid retaining tape 1 is provided with a groove 3 for bending at both ends in the longitudinal direction on the surface of the central portion in the width direction, and a plurality of first and second slits 4 on each edge on both sides in the width direction. 5 is provided.

Each tongue piece between the first slits 4 and 4 is chamfered at its edge and curved as shown in FIG.

  The bending groove 3 causes the substantially U-shaped heating part of the high-frequency heater to contact the surface of the liquid-retaining tape 1, and the liquid-retaining tape 1 is held at a temperature lower than the melting point of the first thermoplastic fiber by the heating part. It is formed by pressing while heating. In addition, since the liquid retaining tape 1 has flexibility, the groove 3 for bending may be provided over both ends of the liquid retaining tape 1 or may be provided in the vicinity of both ends. In addition, the groove 3 may be continuous or discontinuous having a non-groove part in the middle of the length direction.
