Description

  The present invention relates to a lip applicator.

Conventionally, in order to apply liquid cosmetics such as lip gloss to the lips, a stick-shaped application body is used, or liquid cosmetics that have been squeezed out of a tube or a rotary feed container are applied to the upper and lower lips via an applicator. It was common to apply to each of these.
However, in these methods, it is necessary to spread at a narrow application portion and it is necessary to spread on the upper and lower lips, so it takes time and is not always a simple method.

  On the other hand, a flat support member having a use surface that can be impregnated with a powdery or liquid paste-like cosmetic material that is elastically deformed by compression by both lips and conforms to the shape of both lips, There has been proposed a makeup device for applying cosmetics to both lips at the same time by the user sandwiching the use surface between both lips. (See Patent Document 1)

However, the device of Patent Document 1 can be used multiple times with a mode in which it is a one-time disposable make-up device and a cosmetic reservoir in which the support member is immersed when not in use. Although the embodiment of the device is disclosed, the one-time-use disposable embodiment requires that the use surface impregnated with the cosmetic is exposed to the cosmetic, so that it needs to be sealed to avoid drying and the like. In the aspect that can be used many times, the structure is complicated and the size is increased.
Furthermore, in the device of Patent Document 1, cosmetics are applied to the entire lips. However, it is desired to apply only to the periphery of the center of the lips, which is preferably performed with lip gloss or the like. It is not possible.

Japanese Patent No. 2911430

  It is an object of the present invention to provide a compact lip applicator that can apply liquid cosmetics to the upper and lower lips in one operation at the same time and quickly and easily on a wide surface.

The present inventor has solved the above problems by adopting a structure in which liquid cosmetics are pressed out from the discharge ports provided on both surfaces of the application part to the surface of the application part.
That is, the present invention relates to a lip applicator for applying liquid cosmetics to the lips, wherein there are discharge ports on both surfaces of the flat-shaped application part, and a section for spreading the liquid cosmetics is provided around the discharge ports. is there.

  According to the present invention, it is possible to provide a liquid lip applicator that can be applied to the upper and lower lips in one operation at the same time, simultaneously and quickly on a wide surface, and is compact.

It is a perspective view of one example of the lip applicator of the present invention. It is a perspective view of the application part of the lip applicator of FIG. It is a perspective view of the accommodating part of the lip applicator of FIG. It is a perspective view of the connection part of the lip applicator of FIG. It is the top view which made the right half of the lip applicator of FIG. 1 the cross section. It is the right view which made the upper half of the lip applicator of FIG. 1 the cross section. It is the perspective view shown in the shape which cut the cover of one example of the lip applicator which provided the cover which covers an application part. FIG. 8 is a perspective view showing an example of the lip applicator of FIG. 7 in a half-cut shape.

Hereinafter, the lip applicator of the present invention will be described with reference to FIGS.
The lip applicator 1 includes an application part 2, a storage part 3 and a connection part 4.
The applicator 2 has a flat shape that can be sandwiched between both lips, and is provided with a discharge port 21 in the vicinity of a portion where the center of both lips comes into contact when sandwiched between both lips on both surfaces. A concave portion 22 having a partially spherical curved surface is provided in a portion from the portion to the front end of the application portion 2.
The storage unit 3 is a hollow container, and has a neck portion 31 that fixes the application unit 2 and guides the stored liquid cosmetic.
The connecting portion 4 has a shape in which a band-like portion 42 is provided at a right angle to the plate-like portion 41 on the periphery of the plate-like portion 41 having a shape corresponding to the end surfaces of the application portion 2 and the storage portion 3 in the joining direction. A through hole 43 is formed in the shape portion 41 for allowing the neck portion 31 of the storage portion 3 to pass therethrough.

The lip applicator 1 is formed by inserting the neck portion 31 of the storage portion 3 into the insertion hole 23 of the application portion 2 through the through hole 43 of the connecting portion 4.
As shown in FIGS. 5 and 6, the insertion hole 23 of the application unit 2 continues to the inside of the discharge port 21 and forms a flow path for the liquid cosmetic.
Thus, when the lip applicator 1 of the present invention is used, an appropriate amount is applied from the two discharge ports 21 provided on each of both surfaces of the application unit 2 by applying pressure to the liquid cosmetic in the storage unit 3. After the liquid cosmetic is pressed out, the liquid cosmetic can be applied to both lips by sandwiching the concave portion 22 of the application part 2 with both lips. In order to apply an appropriate amount without the liquid cosmetic material sticking out to the lips, it is preferable that the application unit 2 has a hardness that does not change its shape following the lip pinching pressure.

The shape of the discharge port 21 in the application unit 2 is a linear shape or an arc shape that intersects at right angles to the direction in which the lip applicator 1 is inserted into the mouth from the portion where the center of both lips contacts when sandwiched between both lips. Is preferable from the viewpoint of spreading the liquid cosmetic by pinching with lips. There may be several discharge ports 21 on one side.
Depending on the type of liquid cosmetics, liquid cosmetics are applied not only to the center of the lips, but also to the case where the lips are rubbed and spread after application to the lips. Since there are various cases, such as when applied to the whole, the total area (opening area) of the discharge ports 21 for each side needs to be adjusted according to the viscosity of the liquid cosmetic, etc., but 0.2 to 65 mm ² This is preferable from the viewpoint of adjusting the application area on the lips. In addition, the said numerical value is taken as the area at the time of opening, when the discharge outlet 21 is a slit.

The distance from the applicator tip of the discharge port 21 is preferable because the liquid cosmetic material adheres to an appropriate site when 5 to 15 mm is sandwiched between the lips.
Further, there is a possibility that the liquid cosmetic extruded from the discharge port 21 on the back side may drop depending on the viscosity of the liquid cosmetic. In this case, the area of one of the discharge ports 21 on the back side is set to the surface side. It is also effective to make the area smaller than the area of one of the discharge ports 21. Note that “front surface” means a surface on which the upper lip hits, and “back surface” means a surface on which the lower lip hits.
Furthermore, making the discharge port 21 on the back side or all the discharge ports 21 into a slit and opening it when applying to the lips so that the liquid cosmetic is discharged can prevent the liquid cosmetic from dripping. It is valid.

The concave part 22 in the application part 2 is a part that can be inserted into the mouth by opening the mouth lightly and easily sandwiched between both lips, and the thickness (thickness from the front surface to the back surface) is suitably 1 to 10 mm. The width is suitably 10 to 50 mm. It should be noted that providing the liquid reservoir on the surface of the concave portion 22 is effective for applying the liquid cosmetic material evenly at a time. The liquid reservoir is provided with a plurality of concave grooves or a plurality of convex portions. Both the concave grooves and the convex portions may be point-like or linear.
7 and 8 show a state in which a large number of dot-like convex portions 25 are provided in the liquid reservoir portion 24. FIG.
However, as long as the whole application part 2 is the said thickness and width, the recessed part 22 does not necessarily need to be provided.

  As described above, the storage unit 3 needs to be able to apply pressure to the stored liquid cosmetic in order to extrude the liquid cosmetic from the discharge port 21 of the application unit 2, for example, an eye drop container It is suitable to have a form that applies pressure to liquid cosmetics by elastically deforming by pinching with fingers, such as those having a feeding mechanism, bottles, tubes, etc. However, there is no problem. A bottle or a tube is preferable from the viewpoint of simplicity of extruding and coating, and it is preferable to have a feeding mechanism from the viewpoint of simplicity of adjusting the discharge amount.

The connecting portion 4 has a role of decoratively hiding the connecting portion between the application portion 2 and the storage portion 3 while inserting and fixing the application portion 2 and the storage portion 3 from both sides. If the portion 2 and the storage portion 3 can be securely fixed and rotation about the neck portion 31 does not occur, it does not necessarily have to be used.
It is preferable to provide a lock mechanism (closing mechanism) in order to prevent liquid cosmetics from being pressed out by pressing the storage portion 3 carelessly. The locking mechanism may be of a type that is normally employed, such as an inner plug, and a type that closes / opens the flow path of the liquid cosmetic.

As a system for operating the lock mechanism, there are a rotary type that rotates a part of the lip applicator component and a pull-up type that lifts (slides) a part of the lip applicator component. If it is a cylindrical shape, it may be a rotary type, but in the case of a flat lip applicator, a lifting type is preferred.
In the pulling-up type, when it is not lifted, it can be closed to ensure airtightness, and when it is lifted, the flow path of the liquid cosmetic can be opened and can be pressed out. On the other hand, when the liquid cosmetic is not lifted, the flow path of the liquid cosmetic can be opened and pressed, and when it is lifted, the liquid cosmetic can be closed and airtight can be secured.

  The rotary type is a method in which the part (inner plug) that closes / opens the flow path is moved by rotation, but when rotating clockwise, the liquid cosmetic flow path is closed to ensure airtightness, When rotated counterclockwise, the liquid cosmetic material can be opened to allow the liquid cosmetic material to be pressed out. On the other hand, when it is rotated clockwise, the flow path of the liquid cosmetic is opened and can be discharged, and when it is rotated counterclockwise, it is closed and airtightness can be secured. The structure which becomes can be taken.

In the example shown in FIGS. 1 to 8, the lip applicator 1 as a whole has a shape similar to a disk with a thin outer peripheral edge and a bulged central portion, and the application unit 2 and the storage unit 3 cut it in half. Although it is such a shape, it is not necessarily restricted to this. However, in order to sandwich the application part 2 between both lips, the end part is preferably an arcuate shape as described above. However, as described above, the storage part 3 has a feeding mechanism or a tube. A bottle having any shape such as a circle, a triangle, a square, a rectangle, a polygon, or the like can be adopted.
Moreover, although the application part 2 is shape | molded solidly in the example shown in FIGS. 1-8, if the discharge port 21 and the insertion hole 23 are provided, it does not interfere even if it shape | molds hollow.

In addition, the cover which covers the whole lip applicator 1 and the application part 2 and / or the accommodating part 3 was provided, and the accommodating part 3 was carelessly pressed and liquid cosmetics were squeezed out, or it remained in the discharge port 21 vicinity. It is appropriate to prevent the clothes and the like from getting dirty by touching the liquid cosmetic. In order to secure fixing and airtightness of the cover, it is preferable to provide a cover that is fitted so as to sandwich the discharge ports 21 on both surfaces.
7 and 8 show an example in which a cover 5 that covers the application portion 2 is provided, and the cover 5 is inserted into a shape that covers the opening end on one side of the belt-like portion 42 of the connecting portion 4. Yes. Further, the cover 5 is provided with two middle foot portions 51 that cover the discharge port 21 on the front surface side and the discharge port 21 on the back surface side. The middle foot portion 51 is preferably sandwiched in such a manner as to cover the discharge port 21.
If the cover has this shape, it is excellent for fixing the cover because it is sandwiched. In addition, since the cover is sandwiched in a form that covers the discharge port 21, the container 3 is carelessly pressed to extrude the liquid cosmetic. It is possible to prevent the liquid cosmetic remaining in the vicinity of the discharge port 21 from soiling clothes and the like. Furthermore, since airtightness can also be ensured, it is preferable.

  The lip applicator of the present invention is suitably manufactured by injection-molding a thermoplastic resin. Examples of elastic materials such as natural rubber, synthetic rubber, and polyurethane, silicone, elastomer, and thermoplastic resin include high-density polyethylene ( HDPE), low density polyethylene (LDPE), linear low density polyethylene (LLDPE), ethylene-α-olefin copolymer, ethylene-vinyl acetate copolymer (EVA), ethylene-methyl methacrylate copolymer (EMMA), Polyolefin resins such as polypropylene, polyester resins such as polycarbonate resin (PC), PET resins, acrylic resins such as methacrylate polymers, polyamide resins, polyacetal resins, acrylonitrile-butadiene-styrene copolymers (ABS), acrylonitrile Available styrene copolymer (AS) and the like, provided that the whole, or it is also possible to manufacture the part of aluminum, brass, a metal such as iron.
