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 portion and an inner plug that fits into the mouth tube portion, and a roller is disposed and supported above the inner plug so that the axial center is in the lateral direction. In the coating container configured to distribute the coating liquid to the surface of the roller through the outflow hole formed in the
It is said that a thick print layer is laminated on the outer surface of the roller to form an uneven pattern by this print layer.

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.

  According to another configuration of the present invention, in the main configuration described above, the printing layer has an average thickness value of 0.1 mm or more and a maximum thickness value of 0.2 mm or more.

In order to sufficiently hold the coating liquid in the concave portions formed between the adjacent print layers, it is preferable that the average value of the layer thicknesses of the print layers is 0.1 mm or more. Moreover, in order to fully exhibit the massage effect, it is preferable that the maximum value of the layer thickness is 0.2 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.

  According to still another configuration of the present invention, in the main configuration described above, a holder member is fitted and arranged on the inner plug while being slidable in the vertical direction and biased upward by a spring. It is said that it is set as the structure which arrange | positions and supports a roller rotatably on a wall.

According to the above configuration, when applying while rotating and moving the roller, the holder member can be slidably displaced in the vertical direction and fitted and disposed in the inner plug while being biased upward by the spring. In addition, 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 coating container having the main configuration of the present invention, the uneven pattern is formed on the roller surface by the thick print layer, that is, by using the screen printing method. A wide variety of concavo-convex patterns can be expanded according to the needs of the individual.

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.

An inner cylinder piece 24 is suspended, and a rectangular cylinder-shaped holding cylinder 26 is erected on the top wall 22. Further, a flange 25 is disposed on the upper end of the outer cylinder piece 23 in the shape of an outer casing.
In addition, on the left and right sides of the peripheral wall of the holding cylinder 26, bearings 27 that function as bearings of the shaft body 32 of the roller 31 are formed. (See Figs. 5 and 6)
In addition, a discharge hole 22a is formed in a rectangular shape in the top wall 22 corresponding to the bottom wall of the holding cylinder 26.

The roller 31 is made of synthetic resin and has a shape in which a shaft body 32 is integrally connected to the left and right end surfaces of a cylindrical main body. In addition, a large number of circular convex portions are formed on the outer peripheral surface by a thick print layer 33 by screen printing, and as a whole, this is a concavo-convex pattern in which a large number of dots are regularly arranged.
Here, as shown in the enlarged view in FIG. 5, each printed layer 33 has a shape in which the central portion is raised, the average thickness is about 0.2 mm, and the maximum height is about 0.35 mm. It is said.

  The cover tube 29 has a rectangular tube shape with a locking peripheral piece 29a formed in an inner collar shape at the upper end, and is fitted on the holding tube 26 of the holder 21 to hold the roller 31 together with the holding tube 26. And it has a supporting function.

The overcap 41 has a cylindrical shape with a top, and is screwed into the mouth tube portion 2 of the container body 1 to cover the upper portion of the container including the holder 21, the roller 31, and the cover tube 29.
Further, a pair of left and right presser pieces 42 are suspended from the lower surface of the top wall.

Next, the assembled state of the six members described above and the usage mode of the application container of this embodiment will be described.
As shown in FIG. 3, the inner plug 11 is assembled and fixed to the mouth tube portion 2 by fitting the fitting tube piece 12 into the mouth tube portion 2 of the container body 1, and is provided around the upper end of the fitting tube piece 12. The insertion limit is determined by the flange 12a.
Further, the holder 21 has the outer cylinder piece 23 fitted between the fitting cylinder piece 12 and the seal cylinder piece 14 of the inner plug 11, and the inner cylinder piece 24 is fitted between the seal cylinder piece 14 and the center cylinder piece 16,
The inner plug 11 is fitted to the inner plug 11 while being slidable in the vertical direction and biased upward by a spring S set between the outer cylinder piece 23 and the seal cylinder piece 14.

Further, the roller 31 is disposed rotatably on the holding cylinder 26 by fitting the left and right shaft bodies 32 into the left and right bearings 27 of the holding cylinder 26 of the holder 21.
The cover cylinder 29 is fitted onto the holding cylinder 26, and the locking peripheral piece 29 a externally covers the roller 31, covers the upper part of the bearing 27, and holds the shaft body 32 in the bearing 27. (See also Figs. 5 and 6)

  In the state where the overcap 41 is removed as shown in FIG. 4, a gap G formed between the outer peripheral surface of the central cylindrical piece 16 of the inner plug 11 and the inner peripheral surface of the inner cylindrical piece 24 of the holder 21 is formed. Utilizing this, a connecting flow path FC from the outflow hole 15a of the inner plug 11 to the discharge hole 22a of the holder 21 is formed.

  In the state where the overcap 41 is mounted as shown in FIG. 3, the presser piece 42 suspended from the lower surface of the top wall of the overcap 41 presses the roller 31 downward, and the holder 21 is biased upward by the spring S. In this case, the lower end of the outer peripheral surface of the inner cylinder piece 24 of the holder 21 is liquid-tightly contacted with the seal protrusion 14a formed on the lower end of the inner peripheral surface of the seal cylinder piece 14 of the inner plug 11. The connecting flow path FC can be brought into a sealed state.

When the overcap 41 is removed at the time of use, the state shown in FIG. 4 is obtained as described above, the sealing state of the communication channel FC is canceled, and when the container is turned upside down, the coating liquid (illustrated) stored in the container body 1 is shown. (Omitted) is distributed to the surface of the roller 31 via the outflow hole 15a, the connecting channel FC, and the discharge hole 22a.
Further, by pressing the body portion 4 of the container main body 1, the amount of the application liquid dispensed can be appropriately adjusted.

Then, in a state where the coating liquid is dispersed on the surface, the roller 31 is coated on the surface to be coated while rotating and moving.
In particular, when the surface to be applied is a body part such as skin, the uneven pattern by the printing layer 33 can give a massage effect with the elastic action effect by the spring S and can be used comfortably. At the same time, the efficacy of cosmetics and drugs can be further enhanced.
