Description

  The present invention can be applied, for example, to a liquid, creamy or powdery coating substance such as cosmetics such as cream, lip gloss, mascara, eyeliner, etc. and paints such as varnish (hereinafter referred to simply as “coated substance” The present invention relates to an applicator and a coating material-containing container with an applicator, which spreads on the surface to be coated.

  Heretofore, there has been proposed an application substance-containing container with an application tool including an application tool having a flat application portion (see Patent Document 1).

JP, 2005-187025, A

The container according to the above patent document 1 is slidably fitted on the outer surface of the plug body with the plug main body having a horizontally long discharge hole communicating with the inside of the mouth of the container main body, and the plug main body can project upward And a horizontal liquid spreading plate.
According to this container, after pushing up the spreading plate to make its tip part protrude from the plug body, by pulling the container body while pressing the container body in a state where the discharge hole of the plug body is directed to the application surface, Since the liquid (application substance) ejected from the ejection holes is extended by the horizontally long spreading plate and applied to the application surface, the application substance can be widely applied in a single application operation.

  However, in this conventional coated substance storage container with applicator, the spreading plate is in line contact with the surface to be coated, so if the pressing force of the spreading plate against the surface to be coated is large, the coating material layer is formed. If the pressing force is small, the thickness of the coating material layer becomes uneven, and neither can form a uniform coating material layer, and the rolled liquid plate does not deform, so the curved surface There is a problem that application to the skin is difficult.

  An object of the present invention is, in view of the problems of the above-mentioned conventional applicator, to provide an applicator and an coated substance container with the applicator capable of forming a uniform coated substance layer on a surface to be coated.

  In order to achieve the above object, in the applicator according to the present invention, the cross-sectional shape of the application section is curved, the application substance is placed on the application surface on the concave side of the curved application section, and the application section is applied. An applicator which applies an application substance to a surface to be coated by moving while pressing the surface to be coated, wherein at least a central portion of a concave surface of the coating portion is pressed by pressing the application portion against the surface to be coated, The coating portion is formed of a flexible resin so as to be in surface contact with the surface to be coated via the coating material layer.

  In this case, by pressing the application part against the application surface, the edges of both sides of the concave part of the application part can be in line contact with the application surface.

  Further, the distal end side of the application part may be opened so as to obliquely intersect the axis of the application part, and the base side may be formed in a tubular shape.

  Further, in order to achieve the above object, the application substance storage container with an applicator according to the present invention is characterized in that the applicator is disposed at an opening of a container main body for containing an application substance.

  According to the applicator and the applicator-containing coated substance storage container of the present invention, at least the central part of the concave surface of the applicator part is in surface contact with the applicator surface through the application substance layer by pressing the applicator part against the application surface. Since the coating portion is formed of a flexible resin as described above, a uniform coating material layer can be formed on the surface to be coated according to the pressing force of the coating portion on the surface to be coated.

Further, by pressing the application portion against the application surface, the edges of both sides sandwiching the central portion of the concave portion of the application portion are brought into line contact with the application surface, thereby enclosing the curved application portion. Side leakage can be prevented by the effect and the scraping effect by line contact.
Here, the side leakage means that when the coating material is applied to the surface to be coated by moving the coating portion while pressing it against the surface to be coated, the coating portion can not be enclosed or scraped off at the coating portion. This is a phenomenon in which the coating substance is left behind on both sides of the coating part, and it seems that the coating substance leaks from both sides (both sides) of the coating part.

  In addition, the distal end side of the application portion is opened so as to obliquely intersect the axis of the application portion, and the base side is formed in a tubular shape, thereby surrounding effect and line contact of the curved application portion. Can further enhance the scraping effect.

<Description of coating operation>
The operation | work which apply | coats an application | coating substance to a to-be-coated surface using the application substance storage container 1 comprised as mentioned above is demonstrated below using FIG. 1 and FIGS. 3-5.

First, the container body 2 (see FIGS. 1A to 1C) is lifted by hand, and the nozzle portion 3a of the lid 3 with a nozzle is directed to the application surface F as shown in FIG. 3A. The container body 2 is inclined to hold the outer peripheral surface of the container body 2 with fingers and pressed with an appropriate pressing force.
Then, the on-off valve (not shown) incorporated in the discharge port portion of the container body 2 is opened, the application substance M in the container body 2 is ejected from the container body 2 and the application substance M ejected from the container body 2 is provided with a nozzle From the plurality of discharge ports 5 (see FIGS. 1 (a) and 1 (b)) provided in the nozzle portion 3a of the lid 3, the inside of the application portion 4b of the applicator 4 is discharged onto the surface F to be coated Be done.

Next, as shown in FIGS. 3A and 3B, the coating substance M is placed on the application surface F on the concave surface 10 side of the curved application unit 4b, and the application unit 4b is pressed against the application surface F. While moving.
At this time, the central portion 10a of the concave surface 10 of the coating portion 4b comes into surface contact with the surface F via the coating material layer in accordance with the pressing force of the coating portion 4b against the surface F to be coated. The edge of the both sides (convex curve shape part 30) which pinched | interposed are deformed so that the to-be-coated surface F may be in line contact.

When the side leakage phenomenon is likely to occur at the time of the application operation described above, the application portion 4b is pressed against the surface F to be applied with a further strong force.

Even when moving along the curved direction of the coated surface F, the central portion 10a of the concave surface 10 of the coated portion 4b follows the shape of the coated surface F via the coated material layer on the coated surface F. In addition to the surface contact, the edges of the convexly curved portions 30 on both sides of the central portion 10 a of the concave surface 10 of the application portion 4 b are in line contact with the application surface F.

  Further, as shown in FIGS. 5 (c) and 5 (d), when the surface to be coated F has, for example, a concave curved surface like the inner peripheral surface of a cylindrical structure, FIG. 5 (c) In the case where the application portion 4b is pressed against the application surface F in the form of a concave curved surface and moved in a direction perpendicular to the bending direction of the application surface F, as shown in FIG. Even when moving along the curved direction of the application surface F, the central portion 10a of the concave surface 10 of the application part 4b follows the shape of the application surface F, and the application substance layer is applied to the application surface F. While being in plane contact with each other, the edges of the convexly curved portions 30 on both sides of the central portion 10a are in line contact with the application surface F.
