DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mat which is directly placed on a desk when exchanging bills, coins, credit cards, etc. between a customer and a clerk at a desk in a store or at a counter of a bank or a hotel. The present invention relates to a coin mat used as a rug laid on the inner bottom of a small tray called a carton.

[0002]

2. Description of the Related Art Conventionally, as a coin mat generally known, for example, as shown in FIG. 3, a flat mat made of a synthetic resin such as vinyl chloride resin or ethylene vinyl acetate resin to a thickness of about 2 to 4 mm is used. There is a sheet formed by projecting a protrusion 2 on the surface of a simple sheet 1 in a brush shape. The protrusions 2 have a diameter of about 1 mm at the base, a length of about 4 mm, and a tip tapered to about 0.5 mm, and are erected at intervals of about 2 mm.

[0003] The overall size and planar shape of the coin mat is a square or a circle having a side or diameter of about 10 cm to 30 cm. Further, in the conventional coin mat, designs such as pictures and characters are drawn at the tips of the brush-like projections 2, but in this case, they are observed only as spot-like designs scattered almost at an interval of 2 mm. Instead, it was necessary to draw all over the bottom of the brush-like projections. However, since it is very difficult to clearly draw the brush-shaped protrusions on the bottom surface, conventionally, a design such as a pattern or a character is drawn on the protrusion surface of the integrally molded product having the brush-shaped protrusions 2. Then, the sheet 3 was laid on the bottom of the brush-like projections while the projections 2 were pierced into the sheet 3, respectively, and were laid on the sheet 1 to express the design. .

[0004]

As a function required of a coin mat, coins and cards placed on a flat and hard table are hard to grasp, so that coins and cards placed on a flat surface are moved with a fingertip. It needs a function that can be easily grasped. Therefore, it is necessary for the coin mat to have a gap in which a finger enters between the coin or the card and the plane when the coin or the card is to be picked up, and that the coin mat does not slide and move when the coin or the card is picked up. In addition, when a group of brush-like protrusions forming the surface of the coin mat is pressed with a fingertip to form a gap to grasp coins or cards, it is good for the customer that the touch when the fingertip comes into contact with the protrusion group is soft. Necessary to make an impression.

[0005] Furthermore, it is also necessary to be able to easily perform decorative design drawing and various character expressions as advertising media. In a conventional coin mat, the brush-like protrusion 2 having a diameter of about 1 to 0.5 mm and a length of about 4 mm, which is raised at intervals of about 2 mm, has a function of easily catching coins and cards with a fingertip. ing. In other words, even if the protrusions 2 are made to have a relatively soft and warm feel, the plasticizer in the molding resin volatilizes as light increases as the coin mat is manufactured over time. However, there is a problem that the brush-like projections 2 are hardened under the influence of oxygen, other gas, and the like, and the feel of the brush-like projections 2 becomes harder.

Therefore, in order to obtain a soft touch, it is conceivable to reduce the diameter of the brush-like projections 2 as a solution. In view of the essential durability of raw materials such as vinyl acetate resin, it is impossible to reduce the diameter of each projection 2 and the current situation has to be accepted.

The present invention has been made to solve such a problem, and when a fingertip comes into contact with the surface of the coin mat when grasping coins or cards placed on the coin mat, Provided is a coin mat that can give a customer a softness and a warm feel that have never existed before without any change over a long period of time, and that can easily draw various designs such as patterns and characters. The purpose is to do so.

[0008]

According to the present invention, there is provided a synthetic resin sheet having a single-fiber fineness of 15%.
The gist is that a pile fabric in which tufted synthetic fiber multifilament yarn of 0 denier or less is placed, and the base fabric surface of the pile fabric is bonded to the surface of the synthetic resin sheet. Further, the present invention is characterized in that the synthetic resin sheet is made of vinyl chloride resin or ethylene vinyl acetate resin, and the synthetic fiber multifilament yarn of the pile fabric is made of nylon bulky yarn. Further, the present invention has a gist that a design such as a picture or a character is drawn on the surface of the pile fabric.

FIGS. 1 and 2 show a coin mat according to the present invention. Reference numeral 11 denotes a synthetic resin sheet serving as a base, and a base cloth surface 13 of a pile fabric 12 is bonded to the surface of the synthetic resin sheet 11. The synthetic resin sheet 11 and the pile fabric 12 are integrated.

[0010]

Embodiments of the present invention will be described below. The synthetic resin sheet referred to in the present invention constitutes the back surface of the coin mat, and preferably has a certain feeling of weight and prevents the coin mat from slipping on the table. Therefore, as a material used for the synthetic resin sheet, for example, vinyl chloride resin, ethylene vinyl acetate resin, or the like is appropriate, and various additives and fillers are used in combination.

In order to manufacture this synthetic resin sheet, an extrusion molding method utilizing thermoplasticity is used. When a vinyl chloride resin is used as a material, a vinyl chloride sol obtained by kneading a plasticizer and vinyl chloride powder is used. Can be heated to form a sheet by gelation.

As the pile fabric constituting the surface of the coin mat of the present invention, a pile fabric obtained by tufting a synthetic fiber multifilament yarn having a single yarn fineness of 150 denier or less is suitable. As the filament yarn, a nylon bulky processed yarn is suitable. In addition, the nylon bulky processed yarn is a processed yarn obtained by crimping a nylon multifilament yarn by a false twisting method, an indentation method, or the like. In the present invention, an indented method is preferably used.

When the single-filament fineness of the synthetic fiber multifilament yarn exceeds 150 denier, the texture of the pile becomes hard and soft when a fingertip touches the surface of the coin mat, which is one of the objects of the present invention. You wo n’t get the feel,
Not preferred. This single yarn fineness is 150 denier or less, more preferably 75 denier or less, and further preferably 3 to 36 denier.

The pile fabric of the present invention has a pile length of 1
10 to 10 mm, pile weight 200 to 2000 g / m
^{It is} about ² carpets. The present invention requires a structure in which the base fabric surface of the tufted pile fabric is bonded to and integrated with the synthetic resin sheet. In the present invention, the bonding technology of the synthetic resin sheet and the pile fabric is specified. Not something.

As a method of integrating the synthetic resin sheet and the pile fabric, the synthetic resin sheet and the pile fabric are bonded with an adhesive or a double-sided tape, or the pile fabric is attached to the surface of the molten synthetic resin sheet. A method in which the base fabric surface is sunk and the synthetic resin sheet in a molten state is solidified and integrated is used.

Specifically, a vinyl chloride sol obtained by kneading a powder of vinyl chloride and a plasticizer for vinyl chloride is placed in a liquid state on a flat plate such as a Teflon sheet and formed into a layer having a thickness of about several mm. And the base surface of the pile fabric is brought into contact with the liquid surface and floated. A heat treatment is performed in this state, and the vinyl chloride sol is gelled and peeled off from a Teflon sheet or the like, whereby a coin mat in which the pile fabric is integrated with the vinyl chloride sheet can be formed.

On the other hand, on the pile mat surface of the coin mat,
Drawing a design such as a picture or character is also one of the objects of the present invention, but in order to achieve this object, a conventional carpet printing technique can be applied as it is.

In other words, before the synthetic resin sheet is integrated, the pile fabric is subjected to a printing process carried out with a carpet, so that an arbitrary design such as a picture or a character can be easily expressed on the pile fabric surface. Is possible.

Next, the present invention will be described by way of examples.
To obtain a pile fabric, single yarn denier is 25,50,
