According to the present invention, in a coating container called a roll-on container provided with a roller, when a massage function is imparted by a concavo-convex pattern formed on a roller surface in accordance with a coating operation, according to the properties of the coating liquid and the user's preference. Therefore, it is a technical problem to be able to form a wide variety of uneven patterns.

Of the means for solving the above technical problem, the main configuration of the present invention is:
It has a container body that erects the mouth tube part and an inner plug that fits into the mouth tube part, and a roller is disposed and supported above the inner plug so that the axis is in the lateral direction. through the outflow hole that opens formed, a structure in which the coating liquid is dispensed on the surface of the roller,
A holder member is fitted and arranged on the inner plug while being slidable in the vertical direction and biased upward by a spring, and a roller is rotatably arranged and supported on the top wall of the holder member. In the manufacturing method of the roller for the application container configured ,
The outer surface of the roller, Ri by the screen printing, by laminating AtsuSakari like printed layer a concavo-convex pattern is formed by the printed layer, the printed layer, 0.1 mm or more the average value of the layer thickness, and layer the maximum value of the thickness of you and above 0.3 mm, in which say.

The said structure forms an uneven | corrugated pattern on the surface of a roller with a thick print layer, and tries to exhibit a massage function using this uneven | corrugated pattern.
Here, the thick print layer can be realized by screen printing, and in general, the layer thickness can be increased by performing multiple overprints.
In particular, in the case of a cylindrical or columnar molded product, as described in Patent Document 2 described above, the peripheral surface of the molded product is curved convexly toward the screen plate used for printing. In the position immediately before and after the position where the printing ink is squeezed from the screen plate toward the surface of the molded product, the plate surface and the surface of the molded product are separated from each other, so the relatively thick print layer should be formed without crushing. Can
Furthermore, with this separation, an upward force is applied to the printing ink, suppressing the flattening of the printing layer due to the flow of the ink, and the protruding height of the printing layer can be increased to 0.3 mm or more. The effect can be exhibited sufficiently.
Note that the thickness of the normal printing layer is about 0.03 mm.

Here, a synthetic resin molded product is generally used for the roller. However, when the concave / convex pattern is directly formed on the outer surface of the roller itself, the concave / convex pattern needs to be engraved in the mold cavity for molding. ,
Even if it is intended to form a wide variety of concavo-convex patterns depending on the coating solution or the user's preference, there are naturally limitations in terms of manufacturing cost or the time required for handling.
Therefore, according to the above configuration, the concave / convex pattern is not formed on the roller itself, but is formed by a thick print layer, that is, by screen printing. Can be spread.

Further, by utilizing the characteristics of screen printing, for example, fine flow paths can be formed in a network on the roller surface to improve the dispersibility of the coating liquid on the roller surface.
Furthermore, according to the thick print layer, the hardness of the print layer can be adjusted by appropriately selecting not only the uneven pattern but also the material composition of the print ink and the curing conditions by UV irradiation and heat of the print layer. For example, it exhibits a soft feel like an elastomer, and further adjusts the compatibility of the printing layer with the coating solution and skin to improve the dispersibility of the coating solution on the roller surface. It is also possible to improve or improve the touch.

In order to sufficiently hold the coating liquid in the recesses formed between the adjacent print layers, the average value of the layer thickness of the print layer is set to 0.1 mm or more, and in order to sufficiently exert the massage effect , the layer thickness The maximum value is 0.3 mm or more.
Note that the upper limit of the thickness of the printing layer is naturally determined by the productivity of the printing process of the printing layer.

  Still another configuration of the present invention is that, in the above-described main configuration, a dot-shaped uneven pattern is formed in the printing layer.

With the above configuration, the printing layer formed in a dot shape by screen printing can sufficiently increase the thickness of the central part to about 0.4 mm by the action of surface tension. The massage effect can be fully exhibited.
Of course, the concavo-convex pattern is not limited to the dot shape. For example, the thickness of the printing layer is such that a large number of thin protrusions are formed in the circumferential direction, in the axial direction, and further in a spiral shape in the circumferential direction. In addition, it can be appropriately determined in consideration of the massage effect, smooth rotation and mobility of the roller, touch, dispersibility of the coating liquid on the roller surface, and the like.

The holder member is fitted and arranged on the inner plug while being slidable in the vertical direction as described above and biased upward by a spring, and a roller is rotatably arranged on the top wall of the holder member. According to the supporting structure, the holder member can be slidably displaced in the vertical direction, and is applied while rotating and moving the roller by fitting and disposing it in the inner plug while being biased upward by the spring. At this time, since it elastically contacts the surface to be coated, the massage effect can be more fully exhibited in combination with the concavo-convex pattern.
Moreover, a favorable touch can be obtained by the elastic contact of the roller, and the application by the roller can proceed smoothly.

Still another configuration of the present invention is the above configuration,
Cover the inner stopper in a liquid-tight manner with the holder member,
A discharge hole is formed in the top wall of the holder member.
A connecting flow path from the outflow hole to the discharge hole is formed by the inner plug and the holder member,
In other words, the coating liquid is distributed to the surface of the roller through the outflow hole, the communication channel, and the discharge hole.

  The above configuration uses a holder member disposed above the inner plug to support and dispose the roller and to disperse the coating liquid in the container body on the roller surface.

Still another configuration of the present invention is the above configuration,
By mounting the overcap on the mouth tube part, the holder member descends and the connection flow path becomes sealed,
Further, the holder member is lifted and displaced by removing the overcap, and the sealing state is eliminated.

With the above structure, the attachment / detachment of the overcap can block or open the flow path of the coating liquid without the user's particular intention, and can be used conveniently.

Since the present invention has the above-described configuration, the following effects can be obtained.
That is, in the method for producing a roller for a coating container having the main configuration of the present invention, the coating liquid is used to form a concavo-convex pattern on the surface of the roller by using a thick print layer, that is, using a screen printing method. The variation of the uneven pattern can be widened according to the type of the user and the needs of the individual user.

Moreover, according to the thick print layer, the hardness of the print layer can be adjusted by appropriately selecting not only the uneven pattern but also the material composition of the print ink and the curing conditions of the print layer by UV irradiation and heat. For example, the soft feel like an elastomer can be exhibited, and the affinity of the printing layer with the coating solution and skin can be adjusted to improve the dispersibility of the coating solution on the roller surface and the coating property to the skin. You can also improve the touch.
