Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cosmetic tool for high-viscosity fluid cosmetics, and more particularly to a cosmetic tool in which a cosmetic container and an application unit are integrally formed.
[0002]
[Prior art]
Many cosmetics that are applied directly to specific parts of the body skin, nails, and the like are high-viscosity fluids such as emulsions, creams, gels, and pastes. Such high viscosity fluid cosmetics are usually provided with application tools such as brushes, spats, brushes and brushes. Typically, the application means is contained in the container in a state where the application means is fixed inside the lid of the container, and the cosmetic means can be used immediately as a cosmetic application tool when removed from the container part together with the lid. Containers and makeup tools are known.
[0003]
On the other hand, in recent years, cosmetic tools have been widespread in which the application means is fixed to the outside of the cosmetic container portion and integrally formed, and the application means is supplied with the cosmetic composition directly from inside the container. This type of cosmetic tool has the advantage that the cosmetic composition in the container is shielded from the outside when used, and drying and contamination of the cosmetic itself can be avoided.
[0004]
JP-A-5-269020 discloses that as a cosmetic tool for applying a viscous cosmetic such as mascara, a cosmetic contained in an airtight cylindrical container is passed through a pipe communicating with an opening of the cylindrical container. A makeup tool for supplying a coating means fixed to the distal end of a tube is disclosed.
[0005]
As similar cosmetic tools, Japanese Patent Application Laid-Open Nos. 54-146157 and 62-27903 disclose fluid cosmetic applicators integrated with a cylindrical container filled with cosmetics. In this case, the application means for receiving the supply of cosmetics from inside the container is a porous pad or brush.
[0006]
[Problems to be solved by the invention]
However, with these makeup tools, the inconvenience that it becomes difficult to take out and use the remaining cosmetics adhered to the inside of the container when the remaining amount of the cosmetics is small due to the structural characteristics of the container as described above. is there.
[0007]
Furthermore, high-viscosity fluid cosmetics such as emulsions, creams, gels, and pastes easily adhere to the inner wall of the container, and it has been practically difficult to use up the cosmetics to the end depending on the structure of the container. For example, in the case of a tube container conventionally used in the case of cream, when the remaining amount of the contents is low, even if the user tries to squeeze out the contents by pressing the tube with a finger from the outside, the contents adhering to the inside of the container are removed. It is difficult to completely remove it. In the case of gels and liquid products, bottle containers equipped with a pump-type dispenser for sucking up contents are often used. However, when the remaining amount of contents is small, it becomes difficult to suck the contents.
[0008]
In addition, high-priced cosmetics are usually provided to consumers in small-volume containers, and if the cosmetics are high-viscosity fluid cosmetics, they cannot be used up until they reach the end of the container. There was potential frustration among consumers due to the relatively high percentage of residues.
[0009]
Under such circumstances, there is a need for a cosmetic tool that can be completely removed from a container and used without wasting even a small amount of the high-viscosity fluid cosmetic.
[0010]
[Means for Solving the Problems]
As a result of intensive studies on the structure of cosmetic tools to solve the above-mentioned problems, the inventors have completed the invention of a new cosmetic tool suitable for high-viscosity fluid cosmetics.
[0011]
That is, the present invention is a cosmetic tool for applying a high-viscosity fluid cosmetic comprising a cylinder, a piston and an application means, wherein one end of the cylinder is open and the other end is closed, An application means is connected to the closed end, and a flow path of the cosmetic composition passes from the inside of the cylinder to a discharge port opened at the tip of the application means, while a piston can be inserted into the cylinder from the open end of the cylinder. The makeup tool according to claim 1, wherein the piston comprises a piston tip portion which is fitted on the inner wall of the cylinder and is movable while being in close contact with the piston, and a rod portion for pushing the tip portion.
[0012]
Furthermore, the present invention also provides a kit for assembling the cosmetic tool as a form for actually distributing the cosmetic tool to consumers.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
The cosmetic tool of the present invention is roughly classified into a storage portion of the cosmetic composition and an application means.
[0014]
The reservoir of the cosmetic composition has a syringe-like structure consisting of a cylinder and a piston. One end of the cylinder is closed and the other end is open. By inserting a piston from the open end side, it is possible to extrude the highly viscous flowable cosmetic composition filled in the cylinder from the discharge port opened on the closed end side of the cylinder.
[0015]
The material of the cylinder may be any material suitable for molding into the shape, and is specifically plastic or glass. The cylinder may be made of a transparent or translucent material so that the remaining amount of the cosmetic composition in the cylinder can be determined, but it is necessary to perform appropriate coloring according to individual circumstances such as when stable storage of cosmetics is required. Is also good.
[0016]
Although the cylinder has a columnar structure, a cylindrical structure having a polygonal cross-sectional shape may be used as long as the purpose of use is not affected.
[0017]
The piston consists of a tip that moves in close contact with the inner wall of the cylinder and a rod that is slightly longer than the entire length of the cylinder. Since the rod portion has a role of pushing the distal end portion by being connected to the distal end portion, it is preferable that the shape of the distal end operation portion is appropriately processed so as to be easily pushed by a finger or the like. As the material of the rod of the cylinder, plastic that can be easily shaped is generally used. The cross section of the rod is not particularly limited as long as it can uniformly press the cross section of the tip portion, but an example is a cross-shaped cross section (see FIG. 3).
[0018]
It is desirable that the tip of the piston seals the cosmetic composition in a container in an air-tight manner, so that leakage of the cosmetic composition can be prevented. In addition, it is necessary to be made of a chemically stable material that does not cause deterioration of itself or contamination of the cosmetic composition due to prolonged contact with the cosmetic composition. Furthermore, it is required that the material be made of a material that slides with an appropriate degree of sliding while being in close contact with the inner wall of the cylinder in accordance with the pressure applied to the piston. Considering these points, a rubber elastic material (polyolefin-based rubber, silicon-based rubber, fluorocarbon-based rubber, or the like) or a soft plastic is suitable for the material of the tip. In order to adjust the degree of sliding (friction) with respect to the inner wall, the contact surface between the tip and the inner wall may be appropriately processed.
[0019]
The tip of the piston may have a structure that is inseparable from the rod portion of the piston, or may have a structure that can be separated. The method of joining the distal end portion and the rod portion is not particularly limited, for example, a type in which a thread and a groove are formed on both sides so that the rod can be screwed into the distal end member and both are screwed together when used, or A wedge-shaped projection may be formed at the tip of the rod, and a hole at which the projection fits may be formed at the member at the tip of the piston, and the rod may be pushed into the tip member during use to integrate the two.
[0020]
However, if both can be separated, it is desirable that the rods are physically integrated when the rod is pushed into the tip, and separated from the tip when the rod is pulled out of the cylinder. With such a piston, even if the piston is pulled out of the cylinder, only the rod comes off while leaving the tip of the piston inside the cylinder, so that air is not accidentally sucked into the cylinder from the discharge port on the closed end side This is advantageous in that air can be prevented from entering the cylinder and the quality of the contents can be protected.
[0021]
When air enters the cosmetic composition in the cylinder, a counter-acting element acts to reverse the piston once pushed in. Therefore, a protrusion may be provided near the open end of the inner wall of the cylinder as a stopper for preventing the cylinder from returning.
[0022]
The cosmetic application means in the present invention is connected to the closed end side of the cylinder, and the application means has a discharge port, and a passage through which the cosmetic composition can flow from the inside of the cylinder to the outside extends to the discharge port. . The shape and area of the cross section of the passage can be appropriately changed according to the application and the shape of the tip.
[0023]
The application means and the cylinder may be manufactured by integral molding, but in some cases, the application means may be manufactured as an independent part detachable from the cylinder.
[0024]
In the latter case, it is convenient to adopt a structure in which an application means having a shape adapted to the protrusion formed on the closed end of the cylinder is attached and detached like a cap. A structure in which the application means is screwed into the protruding portion in a threaded manner may be used. However, in any of the mounting methods, the two need to be firmly adhered so that the application means does not come off due to the pressure applied when the cosmetic is discharged, and the cosmetic does not leak from the gap between the joints.
[0025]
The shape of the application means can be appropriately selected in consideration of the type of cosmetic to be applied, the effect, the viscosity, the site to which the cosmetic is applied, the application area, but the shape and the tip of the material which do not damage the application site can be selected. It is appropriate to use. Therefore, when the tip has a rigid shape, a non-sharp tip shape such as a sphere, a flat sphere, a spheroid, a cylinder, and a roll structure is preferable.
[0026]
In addition, in order to efficiently perform application to a wide range of sites, a tip portion that is processed and deformed into a spatula or comb shape is preferable.
[0027]
In addition, brushes and brushes are also useful as shapes that enable uniform application, application to narrow areas, or application of cosmetics with slight differences in shading.
[0028]
The material of the tip portion may be either hard or soft plastic depending on the application, and it is also possible to use a sponge-like material which is used for usual application of cosmetics after processing it into an appropriate shape.
[0029]
The cosmetic tool of the present invention can provide a consumer with cosmetics pre-filled in a cylinder. Therefore, there is an advantage that the cosmetic composition inside the cylinder is shielded from the outside, and is hardly affected by contamination or drying.
[0030]
When a large amount of cosmetic is filled in the cylinder, the piston jumps out of the cylinder greatly. Therefore, there is a concern that the piston or cap is easily detached by an external impact and the cosmetic flows out. In such a case, it would be convenient if the piston rod part could be stored or transported separately from the cylinder body and provided in the form of a kit that allows the consumer to assemble a makeup tool himself during use.
[0031]
Therefore, in the cosmetic tool of the present invention, together with the rod portion separated from the distal end of the piston, the space between the distal end of the piston and the discharge port in which the distal end of the application means is closed by the stopper is filled with the cosmetic composition. May be provided as an assembly kit.
[0032]
Still further, the makeup tool of the present invention has a coating means separated from the cylinder and a rod portion separated from the tip of the piston, and a gap between the tip of the piston and the discharge port whose protruding portion at the closed end is sealed by a plug. It is also possible to provide a cylinder in which the cosmetic composition is filled in the space as an assembling kit.
[0033]
In the case where the application means is detachable, the kit may be provided with a set of a plurality of detachable application means having different shapes depending on the nature and use of the cosmetic, or a set of the application means. Some or all may be provided separately from the cosmetic filling cylinder.
[0034]
