Description

  The present invention relates to an application material delivery container for delivering application material.

  Conventionally, various kinds of coating material delivery containers are known. For example, Japanese Patent No. 3513099 describes a stick-shaped cosmetic material delivery container. The rod-like cosmetic material delivery container comprises a container body comprising a front cylinder and a container body cylinder rotatably connected to the front cylinder, and a core chuck push bar having a chuck which is inserted into the container body and holds the rod-like cosmetic material. , And a cap.

  A longitudinal groove is provided on the inner surface of the container main body cylinder, and a longitudinal rib is provided on the outer surface of the core chuck push rod, and rotation of the core chuck push rod relative to the container main body cylinder is stopped by engaging the longitudinal rib in the longitudinal groove. The mechanism is configured. Further, a spiral groove is formed on the inner surface of the front cylinder, and a spiral engagement portion is formed on the outer surface of the core chuck pressing rod, and a screwing mechanism is configured by screwing this spiral engagement portion and the spiral groove. Be done. The rotation prevention mechanism and the screwing mechanism described above constitute a feeding mechanism for the rod-like cosmetic material. When the front barrel and the container body barrel are relatively rotated, the rotation stopping mechanism and the screwing mechanism operate to draw out the lead chuck push rod. The rod-like cosmetic material protrudes from the tip end opening hole of the front cylinder by the delivery of the core chuck pressing rod.

  A scraping portion is provided inside the cap of the rod-like cosmetic material delivery container. The tip of the rod-like cosmetic material is in contact with the scraping portion, and the tip of the rod-like cosmetic material is scraped by rotating the rod-like cosmetic material in a state where the tip of the rod-like cosmetic material is in contact. The shape of the tip of the scraped rod-like cosmetic material is conical.

Patent No. 3513099 gazette

  In the rod-like cosmetic material delivery container described above, the tip of the rod-like cosmetic material has a conical shape. Therefore, immediately after shaving the tip of the rod-shaped cosmetic material, it is possible to draw a thin line by applying the pointed top of the tip. However, if the tip is in the shape of a cone, the apex is rounded at a relatively early timing while drawing, so it becomes impossible to draw thin lines gradually. In addition, since the tip may be rounded immediately, if you want to draw a thin line, you have to cut the tip again. Therefore, since it is necessary to scrape the tip one by one in order to draw a thin line, the problem that a thin line can not be drawn easily may occur.

  An object of the present invention is to provide a coating material delivery container which can easily draw a thin line.

  The application material delivery container according to the present invention comprises a delivery mechanism for delivering the solid application material extending in the axial direction in the axial direction, and a front cylinder having an opening for holding the application material. In the coating material delivery container, the shape of the opening viewed from the front side is a shape expanding in the long axis direction and the short axis direction, and the front cylinder has a front end extending in the long axis direction, an axial direction and a short axis direction A front cylinder inclined surface formed on one side in the minor axis direction with respect to the front end, and the opening extends obliquely backward from the front end, and the front cylinder inclined surface is an outer side of the front cylinder It is a curved surface that is curved to swell.

  The coating material delivery container includes a front cylinder having an opening for holding a solid coating material extending in the axial direction, and the shape of the opening when viewed from the front is a shape that expands in the long axis direction and the short axis direction It is assumed. That is, when viewed from the front side, the opening has a shape extending in the long axis direction. The front end of the front barrel extends in the longitudinal direction. The tip of the application material held by the front cylinder having such a shape is shaped along the opening of the front cylinder and the front cylinder inclined surface through the use of the application material. That is, the tip of the coating material has a shape extending in the major axis direction following the shapes of the opening of the front barrel and the front barrel inclined surface. In addition, through the use of the coating material, the coating material is formed with an inclined surface along the shape of the front cylinder inclined surface. A thin line can be drawn cleanly on the part to be coated by bringing the tip of the coating material having a shape extending in the long axis direction into contact with the part to be coated and moving the coating material along the long axis direction. In addition, since the tip of the coating material has a shape extending in the long axis direction, the tip is less likely to be rounded even when the application is continued, as compared with the case where the tip is conical. Therefore, it is possible to easily draw a thin line because it is possible to reduce the time and effort of scraping the coating material when drawing a thin line. Furthermore, since the front cylinder inclined surface formed on one side with respect to the front end of the front cylinder is curved so as to expand outward of the front cylinder, the tip of the coating material passes through the use of the coating material, It is curved in a curved shape so as to expand outward following the inclined surface of the cylinder. A thin and short line and a thin and long line can be more easily drawn by applying a curved tip to the application portion so as to bulge outward in this manner. Furthermore, by moving the cutter such as a cutter along the front cylinder inclined surface to scrape the coating material, it is possible to easily form the inclined surface of the coating material along the curved front cylinder inclined surface so as to expand outward. it can. As a result, it is possible to easily form a tip with which a thin line can be drawn cleanly and a coating material provided with the inclined surface.

  Further, the front cylinder inclined surface may be a curved surface formed by a locus of an acute angle line when moving a straight acute angle line inclined to the axial direction and the short axis direction. In this case, it is possible to easily form a front cylinder inclined surface which is curved so as to expand to the outside of the front cylinder.

  According to the present invention, thin lines can be easily drawn.

The cap C includes a cylindrical portion C1 which is directed rearward and into which the front barrel 3 is inserted from the rear, and a scraped portion C2 which is located forward of the cylindrical portion C1. For example, the cylindrical portion C1 and the cut portion C2 are integrally formed. The cylindrical portion C1 has a plurality of protrusions C3 engaged with the inserted front barrel 3 on the inner peripheral surface thereof. The front barrel 3 is engaged with the cap C by inserting the front barrel 3 between the plurality of axially extending protrusions C3.

  The cutting portion C2 includes a tip portion C4 which is formed in an oval shape when viewed from the front side, and a blade portion C5 positioned behind the tip portion C4. When the blade C5 is cut in a plane orthogonal to the longitudinal direction of the cap C, the cross-sectional shape has an end sharpened to project one end along the long axis of the oval in the long axis direction. It has a shape (tears).

  By removing the cap C from the front barrel 3 and applying the blade portion C5 to the coating material M, it is possible to scrape the coating material M. Specifically, as shown in FIG. 10, the cap C is held by hand and the blade portion C5 is moved along the front cylinder inclined surface 3b (or the acute angle line A) of the front cylinder 3 to scrape the coating material M. Such a coating material inclined surface M2 is formed along the front barrel inclined surface 3b.

  The feeding of the coating material M will be described. When the coating material M is fed out from the front cylinder 3, as shown in FIGS. 1 and 2, the front cylinder 3 and the container main body 4 are relatively rotated in one direction (for example, clockwise) with the cap C removed. Then, the front barrel 3, the middle barrel 9 and the female screw member 6 rotate in synchronization, and the container body 4, the spring member 7, the tail plug 8 and the moving body 5 rotate in synchronization, and the female screw 6 a and the movement of the female screw member 6 The screwing action of the screwing portion 10 constituted by the male screw 5a of the body 5 works to move the moving body 5 forward.

  The coating material M is projected forward from the opening 3c of the front cylinder 3 by the forward movement of the movable body 5, and the coating material M is dispensed, and the coating material M is applied to the coating portion to apply the coating material M. It will be. The tip cylinder 3, the container main body 4, the movable body 5, the female screw member 6, the spring member 7, the tail plug 8 and the middle cylinder 9 constitute a feeding mechanism for feeding the coating material M in the axial direction.

  As described above, the coating material delivery container 1 includes the solid coating material M extending in the axial direction and the front cylinder 3 for holding the coating material M, and as shown in FIGS. 3, 5 and 6, from the front side The shape of the coating material M when viewed is a shape that spreads in the long axis direction D1 and the short axis direction D2. When viewed from the front side, the coating material M has a shape that extends long in the long axis direction D1. Further, the leading end M1 of the coating material M has an acute angle and extends in the long axis direction D1. Therefore, by applying the tip M1 of the coating material M extending in the long axis direction D1 to the portion to be coated and moving the coating material M along the long axis direction D1, a thin line can be drawn cleanly on the portion to be coated it can.

  Further, since the tip M1 of the coating material M is formed to extend in the long axis direction D1, for example, the tip M1 becomes round even if the coating is continued compared to the case where the tip of the coating material is conical. It is hard to be. Therefore, since it is possible to reduce the time and effort of scraping the coating material M when drawing a thin line, it is possible to easily draw a thin line.

  Furthermore, when the application of the coating material M is continued and the tip M1 is rounded, the coating material M is slightly drawn out and the coating material M is scraped along the front cylinder inclined surface 3b with the blade portion C5 or a cutter. The tip M1 can be easily returned to an acute angle, and a thin line can be easily drawn. In addition, along the front cylinder inclined surface 3b, even if the coating material M is polished with a surface having different roughness such as paper, sandpaper, a film whose surface is processed to be uneven, or tissue paper, the desired acute angle Can be easily regenerated.

  Further, the tip M1 linearly extends along the long axis direction D1. That is, the tip end M1 of the coating material M is in the form of a line extending long in the long axis direction D1. Therefore, when the coating material M is moved along the long axis direction D1 to perform coating, a thin line can be drawn cleanly along the linear tip M1. Therefore, a thin line can be drawn smoothly along the tip M1.

  Further, the coating material inclined surface M2 is formed along the front cylinder inclined surface 3b, and is formed on one side of the tip M1 in the minor axis direction D2. That is, the coating material inclined surface M2 is formed on one side of the tip M1 of the coating material M, and the coating material inclined surface M2 is formed along the front cylinder inclined surface 3b. Therefore, the coated material inclined surface M2 can be easily formed by moving the cutter such as a cutter along the front cylinder inclined surface 3b to scrape the coated material M. Therefore, it is possible to easily form the coating material M provided with the tip M1 and the coating material inclined surface M2 which can draw thin lines cleanly.

  In addition, the coating material inclined surface M2 and the front cylinder inclined surface 3b extend linearly along the acute angle line A inclined with respect to the axial direction and are curved so as to expand to the outside of the coating material M and the front cylinder 3 It is a curved surface. Therefore, the front end M1 of the coating material M can be curved because the coating material inclined surface M2 and the front cylinder inclined surface 3b are curved so as to expand outward.

  Further, the tip end M1 is curved in a curved shape so as to expand outward of the coating material M and the front barrel 3. Therefore, since the tip M1 is curved so as to expand outward, by applying the tip M1 to the portion to be coated, it is possible to draw a thin and short line or a thin and long line more easily. That is, since the tip M1 is a curve that bulges outward, by applying along the tip M1, it is possible to more easily draw thin and short lines like hair and thin and long lines.

  Further, the front barrel 3 has an opening 3c for holding the coating material M, and the opening 3c is formed to extend from the front end 3d to one side and the rear side in the long axis direction D1. Therefore, when the opening 3c extends on one side in the long axis direction D1, the inner wall 3h on which the coating material M is opposed can be provided on the other end side of the opening 3c in the long axis direction D1.

  In addition, the opening 3 c has an inner wall surface 3 h facing the coating material M on the other side in the long axis direction D 1. Therefore, even when an external force is applied to the coating material M when coating is performed with the coating material M or when the coating material M is scraped, chipping and breakage of the coating material M can be suppressed. That is, when an external force is applied to the coating material M, the coating material M is pressed against the inner wall surface 3 h and the inner wall surface 3 h holds the coating material M, so that chipping and breakage of the coating material M can be prevented. .

A boundary line 23 n extends between the front barrel inclined surface 23 b and the rear inclined surface 23 g. The front barrel inclined surface 23b and the rear inclined surface 23g both extend in a direction inclined with respect to the axial direction. The inclination angle of the front barrel inclined surface 23b is larger than the inclination angle of the rear side inclined surface 23g.

  As shown in FIGS. 15 and 16, the coating material N has a tip N1 which is fed forward from the opening 23c of the front cylinder 23 and extends along the major axis direction D1 intersecting the axial direction. The shape of the coating material N when viewed from the front side is a shape that expands in the major axis direction D1 and the minor axis direction D2. The tip N1 has an acute angle. The tip N1 is linear extending in the long axis direction D1, and the width of the tip N1 is gradually narrowed from one side (left side in FIG. 16) to the other side (right side in FIG. 16) of the long axis direction D1. It has become.

  The coating material N has a coating material inclined surface N2 extending in a direction inclined with respect to the axial direction from the tip N1.

The front barrel inclined surface 23b and the coating material inclined surface N2 are formed in a pair on both sides of the short axis direction D2 with respect to the tip N1. That is, the coating material inclined surfaces N2 are formed on both sides in the minor axis direction D2 of the tip N1, and the front cylinder inclined surfaces 23b are provided in a pair along the extension lines of the coating material inclined surfaces N2. For example, the front barrel inclined surface 23b and the coating material inclined surface N2 are provided symmetrically above and below the tip N1.

  As shown in FIGS. 17 and 18, the front barrel 23 has an inner wall surface 23 h facing the coating material N inside the opening 23 c. The inner wall surface 23h faces the wide first side surface N3 on one side of the major axis direction D1 of the coating material N. A curved surface N5 that curves to the outside of the coating material N is formed between the first side surface N3 and the tip N1.

  The first side surface N3 is continuous with the widened portion of the tip N1 via the curved surface N5. The first side surface N3 is flat, and the curved surface N5 and the tip N1 are curved. The distal end N1 narrows in width as it goes from one side to the other side in the long axis direction D1 and is curved backward.

The coating material inclined surface N2 is curved so as to expand outward of the coating material N as it goes from the first side surface N3 to the second side surface N4. In other words, the coating material inclined surface N2 is curved in a curved shape from the first side surface N3 to the second side surface N4, and the coating material inclined surface N2 is formed between the first side surface N3 and the second side surface N4. The width is approximately constant.

The coated material inclined surface N2 is formed along the front cylinder inclined surface 23b.

  When the coating material N is delivered from the front cylinder 23, as shown in FIGS. 13 and 14, the front cylinder 23 and the container main body 4 are relatively rotated in one direction (for example, clockwise) with the cap C removed. Then, the front barrel 23, the middle barrel 9, and the female screw member 6 rotate in synchronization, and the container body 4, the spring member 7, the tail plug 8 and the moving body 5 rotate in synchronization, and the screwing action of the screwing portion 10 works. As a result, the mobile unit 5 moves forward. The coating material N is projected forward with respect to the opening 23c of the front cylinder 23 by the forward movement of the movable body 5, and the coating material N is drawn out, and the coating material N is applied to the portion to be coated. Is done.

Therefore, by applying the tip N1 of the coating material N extending in the long axis direction D1 to the portion to be coated and moving the coating material N along the long axis direction D1, a thin line can be drawn cleanly on the portion to be coated it can. Therefore, the same effects as in the first embodiment can be obtained from the coating material delivery container 21.

  Further, the coating material inclined surface N2 is formed along the front cylinder inclined surface 23b, and is formed on both sides in the minor axis direction D2 with respect to the tip N1. Therefore, the coating material inclined surface N2 is formed on both sides of the tip N1 of the coating material N, and the coating material inclined surface N2 is formed on the extension of the front cylinder inclined surface 23b. Therefore, when the coating material N is scraped along the front cylinder inclined surface 23b, the coating material sloped surface N2 is naturally exposed on the front end side of the front cylinder 23, so that coating can be performed immediately after the scraping. That is, the coating material N can be applied without taking out the coating material N after scraping. Thus, it is easier to draw thin lines.
