Description

  TECHNICAL FIELD The present invention relates to a container for storing a viscous cosmetic material such as lip gloss or nail color, which can be directly applied by holding the container in hand.

  Conventionally, viscous cosmetics such as lip gloss and nail color have been stored in bottle-type containers and applied to lips etc. using a makeup brush, etc. A cosmetic container with an application function that can be applied while holding the container in the hand and pushing out the viscous cosmetic material that is a small amount from the tip of the container while applying the tip of the container to the lips. However, there are many.

  As such a cosmetic container with an application function, for example, the one shown in FIG. 7 can be cited (see Patent Document 1). This container is provided with a container 1a for viscous cosmetics in a cylindrical container body 1, and a dispensing port 3 for discharging the viscous cosmetic in the container 1a to the inclined tip wall 2 thereof. Are provided. Then, on the lower side of the storage portion 1a, a rotating plate 4 attached to the bottom side of the container main body 1 is rotated so as to rise by a predetermined pitch via the feeding bar 5. Is attached, and the viscous cosmetic in the storage portion 1a is pushed out from the dispensing port 3 little by little as the inner plate 6 is raised.

  Accordingly, the container is held in hand, the rotating body 4 is rotated to push out the viscous cosmetic material (for example, lip gloss) from the distribution port 3 of the tip wall 2, and the upper surface of the inclined tip wall 2 is used to lip. If applied, it has the advantage that makeup can be easily applied.

However, since the tip wall 2 pressed against the lips or the like is made of hard plastic and the touch at the time of application is not preferable, the container has, for example, continuous pores at the tip as shown in FIG. There has been proposed one in which a coating core 10 made of a resin porous body having a surface is attached (see Patent Document 2). 11 is a through-hole for introducing a viscous cosmetic.
JP 2005-168745 A JP 2006-141979 A

  Certainly, according to the coating core 10 of the above-mentioned Patent Document 2, the feeling at the time of coating is improved to some extent as compared with that of Patent Document 1. However, in both types of Patent Documents 1 and 2, the solvent and moisture gradually contained in the cosmetic from the distribution port 3 provided in the tip wall 2 of the container and the through-hole 11 (+ continuous pores) of the coating core 10 Due to volatilization, there is a problem that the viscous cosmetic material extruded first has poor growth and is difficult to make up.

  In addition, since the openings of the distribution port 3 and the through-hole 11 are relatively large, dust in the air, germs attached to the skin, etc. are easily taken into the opening and become filthy, so the application surface applied to the skin is cleaned. There is a problem that can not be kept.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide an excellent cosmetic container with an application function, in which the viscous cosmetic is difficult to dry and the application surface can be kept hygienic. .

  In order to achieve the above object, according to the present invention, a cosmetic applicator made of a substantially celestial cylindrical elastic body is attached to one end of a substantially cylindrical cosmetic container that stores viscous cosmetics. And a cosmetic container having a cosmetic extruding part attached to the other end side of the cosmetic containing part, which applies a pressing action to the stored viscous cosmetic and pushes it out to the liquid applying part side. A slit extending in the left-right direction is formed on the top surface of the part, and the viscous cosmetic is pushed out from the slit by the extrusion operation of the cosmetic extrusion part, and is provided for application. The cosmetic container is a first gist.

  In addition, the present invention has, in particular, a cosmetic container with an application function, in which the top surface of the cosmetic application part is an inclined surface inclined by 15 to 60 ° with respect to a horizontal plane. Furthermore, a cosmetic container with an application function in which the top surface of the cosmetic application part is set to be a concave surface having an arc shape with a curvature radius R of 5 mm or more in the longitudinal section is a third gist.

  That is, the cosmetic container with an application function of the present invention is substantially provided with a slit extending in the left-right direction on the top surface as a cosmetic application unit for extruding and applying the viscous cosmetic stored in the storage unit. A top-like elastic body is used. Therefore, according to this container, the application surface of the adhesive cosmetic is formed of an elastic body, and not only the touch at the time of application is good, but also the gap between the slits opens and closes, and the viscous cosmetic is extruded each time. Therefore, there is an advantage that the viscous cosmetic material in the inside hardly touches the air, and the solvent and moisture hardly evaporate from the viscous cosmetic material. In addition, since the gap between the slits is closed even after the coating operation, there is an advantage that the inside of the slit can be kept relatively clean.

  Among the cosmetic containers with an application function of the present invention, in particular, the top surface of the cosmetic application part is inclined by 15 to 60 ° with respect to the axial direction of the cosmetic storage part, or further, the top If the surface is set to a concave surface having an arc shape with a radius of curvature R of 5 mm or more, it is easy to apply cosmetics by applying the top surface of the cosmetic application part to the skin or lips, In addition, at that time, the gap between the slits is difficult to open, and excess cosmetics hang down, and dust and bacteria are difficult to enter from the slit opening, so that it can be used more hygienically.

  Next, the best mode for carrying out the present invention will be described. However, the present invention is not limited to this embodiment.

  FIG. 1 is a perspective view showing an example of the best embodiment of the present invention, and FIG. 2A is a cross-sectional view taken along the line AA ′. In these drawings, reference numeral 20 denotes a cylindrical container main body, and the inside is formed in a cosmetic storage part 21 for storing viscous cosmetics. A cosmetic applicator 22 made of a silicone rubber elastic body (thickness 1 mm) formed in a substantially cylindrical shape is attached to the upper end of the cosmetic container 21. On the lower side, an inner plate that abuts the lower surface of the cosmetic container 21 and a mechanism for raising the inner plate (not shown) are built in, and a circuit provided at the lower end of the container body is provided. By rotating the moving body 23 as indicated by an arrow, the inner dish is raised by a predetermined pitch via the built-in mechanism, and the viscous cosmetic in the cosmetic storage unit 21 is applied to the cosmetic application unit. It can be pushed to the 22 side. Therefore, the “cosmetics extruding portion” of the present invention is configured by the above-described inner plate, its raising mechanism and the rotating body 23.

  The cosmetic application portion 22 will be described in more detail. The peripheral wall portion 22a is slightly reduced in diameter toward the top, and has a gentle curved surface as a whole. The top surface 22b is inclined at an inclination angle of 40 ° with respect to the horizontal plane, and the inclined surface is a concave surface with a longitudinal radius of curvature R of the top surface 22b of 18 mm.

  Further, as shown in FIG. 2B, a linear slit 24 extending in the left-right direction is formed in the center of the top surface 22b. The gap width D of the slit 24 is 0.02 mm, and is actually almost closed. The length L of the slit 24 is 1.2 mm.

  And the flange 22c is formed in the outer periphery of the lower end part of the said cosmetics application part 22, The lower surface of this flange 22c is contact | abutted to the upper end edge of the container main body 20, and it tightens with the sleeve 25, Cosmetics The application unit 22 is fixed to the upper side of the storage unit 21. That is, by engaging the annular groove 25 a formed on the inner peripheral surface of the sleeve 25 and the annular protrusion 20 a formed on the outer peripheral surface of the container body 20, both of them fasten and fix the flange 22 c of the cosmetic applicator 22. To do. Reference numeral 40 denotes a cap that is detachably attached to protect the cosmetic applicator 22.

  Therefore, in this cosmetic container with an application function, the rotating body 23 provided at the lower end of the container body 20 is rotated in a state where the cosmetic container 21 and the cosmetic application unit 22 are filled with the viscous cosmetic. Thus, the viscous cosmetic can be pushed out from the slit 24 of the cosmetic application unit 22 little by little, and the viscous cosmetic can be applied to the lips and the like using the top surface 22b of the cosmetic application unit 22.

  At this time, since the slit 24 is a very narrow gap, the slit 24 is opened only when the viscous cosmetic is extruded, and is closed after use, and the airtightness in the slit 24 is maintained, so that moisture contained in the inner viscous cosmetic is maintained. It has a structure that is difficult for evaporation of solvents and solvents. Therefore, the viscosity of the viscous cosmetic material is always kept good, and the extruded viscous cosmetic material does not become difficult to apply at the first application. Moreover, since dust and germs are difficult to enter from the gap of the slit 24, it is hygienic.

  In the above example, the material of the cosmetic applicator 22 is not limited to silicone rubber, and any material can be used as long as it is easily elastically deformed and maintains its shape even when repeatedly deformed. Also good. Examples thereof include nitrile rubber (NBA), ethylene-propylene-copolymer rubber (EPR), butyl rubber (IIR), polyurethane rubber, polyethylene rubber, polypropylene rubber and the like. However, it is preferable to use the silicone rubber in terms of chemical resistance, shape imparting property, and the like. The hardness (rubber [shore] hardness) is preferably 60 to 90 in view of application workability and good feeling on the skin (including lips).

  The thickness is not limited to the above example, and is preferably set to 0.8 to 2 mm. That is, when the thickness is less than 0.8 mm, the strength is weakened and the opening of the slit 24 is easily stretched. On the other hand, when the thickness exceeds 2 mm, the feeling of following the skin is poor at the time of application work, and the touch is poor. This is because there is a risk of becoming.

  In the above example, the width D of the slit 24 formed in the cosmetic applicator 22 is usually preferably set to 0.2 mm or less, although it depends on the material and thickness of this portion. In other words, it is desirable that the slit has no gap in the closed state (D = 0 mm). Conversely, when the slit exceeds 0.2 mm, the liquid dripping or the moisture or solvent of the inner viscous cosmetic is removed. It tends to evaporate and is not preferable. Further, the length of the slit 24 is not particularly limited. However, if the slit 24 reaches the peripheral edge of the top surface 22b, the slit 24 may be opened even when the extrusion operation is not given, which is not preferable.

  In the above example, the shape of the slit 24 is a straight line extending left and right. However, the shape is not particularly limited, and as shown in FIGS. 3A and 3B, a shallow U It may be in the shape of a letter, or it may be in the shape of a shallow V, as shown in FIGS. Those having these shapes are preferable because the gaps of the slits 24 can be appropriately opened and closed as compared with those having a straight side. However, when the top surface 22b of the cosmetic application part 22 is an inclined surface, it is desirable that the slit 24 is formed so as to cross the inclined direction.

  For example, as shown in FIG. 4, a plurality of slits 24 (two in this figure) may be provided on the top and bottom. However, it is necessary to ensure a sufficient interval between the slits 24 and 24 ′ so that the opening and closing of the gap between the slits 24 and 24 ′ is not impaired even when the viscous cosmetic material is repeatedly extruded.

  In the above example, the top surface 22b of the cosmetic application part 22 is inclined with respect to the horizontal plane, and the inclined surface is a concave curved surface. However, the inclination angle θ is not limited to the above example. It is preferable to set appropriately between 15 and 60 degrees. Further, the curvature radius R of the vertical cross section of the top surface 22b is not limited to the above example, but is preferably set to 5 mm or more from the viewpoint of coating workability and difficulty in opening the slit 24. .

  However, the top surface 22b does not necessarily need to be a concave curved surface. For example, as shown in FIG. 5A, the top surface 22b may be a flat inclined surface, or in some cases, as shown in FIG. 5B. Thus, it can also be a convex curved surface.

  Further, the overall shape of the cosmetic applicator 22 is not limited to the above example, and the top surface 22b need not be inclined. For example, as shown in FIG. 6A, the top surface is made horizontal and crushed in the front-rear direction, or as shown in FIG. Can be used in a small circle.

  Furthermore, the configuration of the extrusion operation unit provided in the lower part of the container body 20 may be any conventionally known one, for example, in addition to a combination of a male screw and a female screw as shown in FIG. A thing using a ratchet mechanism, or a thing using a knock type irrespective of rotation of rotation part 23 may be used.

  The configuration of the container body 20 is not particularly limited as long as it has a substantially cylindrical cosmetic container 21 inside thereof. For example, irregularities for decoration are provided around the container body 20. May be. Moreover, what changed the kind and color of the inside viscous cosmetics into a set may be used.

  In these examples, the cosmetic storage unit 21 and the cosmetic application unit 22 may be configured to be completely in communication as shown in FIG. 1, but troubles such as liquid leakage do not occur. For example, as shown by a chain line in FIG. 1, an upper plate 30 having a communication hole in the center is attached to the cosmetic storage unit 21, and the communication hole of the upper plate 30 and the slit 24 of the cosmetic application unit 22 The viscous cosmetics may be pushed out through the communication path 31 by providing the communication path 31 that communicates with each other.

  In addition, the viscous cosmetic material stored in the cosmetic container with a coating function of the present invention is not particularly limited, and lip gloss, lip color, eyeliner, serum, nail color, nani remover, hair color, massage Various liquid cosmetics such as oil can be mentioned. In particular, from the viewpoint of prevention of dripping, etc., a material having no viscosity at all and a material having a certain degree of viscosity is preferably used.
