Detailed Description
The liquid cosmetic container of the present invention is characterized by comprising:
a container body having an opening and a receiving portion; and
a stretchable net covering the opening,
the storage part stores the aqueous liquid cosmetic,
the stretchable web is subjected to a waterproof treatment.
The present invention will be described below.
The container body constituting the liquid cosmetic container of the present invention includes an opening portion and a receiving portion, and the receiving portion receives the aqueous liquid cosmetic. The receiving portion preferably has 1 bottom.
The material of the container body is arbitrary, and may be: inorganic materials such as metals and ceramics; organic materials such as paper and resin; or a composite thereof.
The opening of the container body is covered with a stretchable net, and the aqueous liquid cosmetic contained in the container body is passed through the stretchable net when in use.
The stretchable net is generally planar but deformable, and when the aqueous liquid cosmetic is used, it is deformed by pressing with a finger or the like, and can be stretched from the opening of the container body into the storage portion (particularly, into the bottom direction in the storage portion). On the other hand, when the aqueous liquid cosmetic is not used, the stretchable net is not deformed and is flat, and does not extend into the storage portion of the container body.
The stretchable web is preferably stretchable vertically downward by 0.5cm or more, more preferably 1cm or more, and still more preferably 1.5cm or more when the horizontally placed stretchable web is pressed downward. The stretchable web particularly preferably reaches the bottom surface of the storage portion when stretched.
When the aqueous liquid cosmetic is used, the elastic net is deformed by pressing the aqueous liquid cosmetic in the storage portion of the container body, so that at least a part of the aqueous liquid cosmetic passes through the mesh of the elastic net. The liquid cosmetic containing water and passing through the mesh of the stretchable net can be applied by being attached to an applicator such as a puff or a cosmetic pencil.
The storage portion of the container body may include a porous member such as a porous sponge or foam, in addition to the stretchable net. In the case where the housing portion of the container body includes a porous member, at least a part of the aqueous liquid cosmetic may permeate into the porous member. However, in the case where the container body housing portion includes a porous member, the stretchable net is not easily deformed into the container body housing portion, and therefore the container body housing portion preferably does not include a porous member.
The material of the stretchable web is not particularly limited, and any material such as an inorganic material such as a metal, an organic material such as a synthetic resin, or a composite thereof can be used. The material of the stretchable web is preferably a synthetic resin, more preferably a thermoplastic resin.
The stretchable web is preferably in the form of a woven fabric or knit fabric made of fibers, more preferably the fibers are made of a synthetic resin, and even more preferably a thermoplastic resin.
Examples of the thermoplastic resin include: polyolefin resins such AS polyethylene, polypropylene, and mixtures thereof, polyester resins such AS polystyrene resins, polylactic acid resins, AS resins (acrylonitrile-styrene copolymers), ABS resins (acrylonitrile-butadiene-styrene copolymers), polyamide resins, PTT (polytrimethylene terephthalate), PBT (polybutylene terephthalate), and PET (polyethylene terephthalate). These resins may be used after being mixed or compounded. As the thermoplastic resin, a polyester resin is more preferable. As the polyester resin, an aromatic polyester resin is more preferable, and PTT, PET, or a composite thereof is still more preferable.
The synthetic resin is preferably not polytetrafluoroethylene or a fluorinated polymer described later.
As the above fiber, a composite fiber can also be used. Examples of the composite fiber include: core-sheath type composite fibers, bicomponent (side-by-side) composite fibers, and segmented composite fibers. More preferably bicomponent (side-by-side) composite fibers. The bicomponent (side-by-side) composite fiber is a structure in which 2 kinds of polymers are combined to form 1 fiber, and 2 fibers composed of different polymers are integrated in the longitudinal direction. Examples of the bicomponent (side-by-side) composite fiber include: toray oceloniex Lycra T400 (registered trademark) as bicomponent fiber of PTT and PET, and the like.
The fibers are preferably composed of synthetic fibers, preferably fibers made of thermoplastic resin, and more preferably bicomponent fibers. The bicomponent fibers described above are preferably composed of polyethylene terephthalate and polypropylene terephthalate. The weight ratio of polyethylene terephthalate and polypropylene terephthalate in the bicomponent fiber is not particularly limited, and may be, for example, 10 to 90:90: 10. preferably 20 to 80:80: 20. more preferably 30 to 70:70 to 30, more preferably 30 to 50: 70-50.
The fiber width of the fibers is not particularly limited, and may be, for example, in the range of 0.01mm to 2mm, preferably 0.05mm to 1.5mm, and more preferably 0.1mm to 1 mm.
The weight per unit area of the stretchable web is not particularly limited as long as the web exhibits stretchability, and may be, for example, 50g/m 2 ～200g/m 2 May preferably be 75g/m 2 ～175g/m 2 More preferably 100g/m 2 ～150g/m 2 。
The thickness of the stretchable web is not particularly limited as long as the web exhibits stretchability, and may be, for example, in the range of 0.01mm to 3mm, preferably 0.05mm to 2mm, and more preferably 0.1mm to 1 mm.
The maximum length of the mesh of the stretchable web is not particularly limited, and may be, for example, in the range of 0.01mm to 0.9mm, preferably 0.05mm to 0.8mm, and more preferably 0.1mm to 0.7 mm.
The maximum opening area of the mesh of the stretchable web may be, for example, 0.01mm 2 ～0.9mm 2 Is preferably 0.05mm 2 ～0.7mm 2 More preferably 0.1mm 2 ～0.5mm 2 Is not limited in terms of the range of (a).
In general, when a cosmetic is used, the mesh of the stretchable net is enlarged by the stretching of the stretchable net, and the cosmetic is easily passed through the stretchable net, but when the cosmetic is not used, the stretchable net is contracted, and the mesh of the stretchable net is reduced, so that the cosmetic is not easily passed through the stretchable net.
However, since the fluidity of the liquid cosmetic is high, even small meshes of the stretchable net are likely to pass when not in use, and for example, if the container is tilted sideways during transportation, the liquid cosmetic may leak from the meshes of the stretchable net.
Therefore, in the present invention, the stretchable web is subjected to a waterproof treatment. Thus, in the present invention, the cosmetic passes through the mesh of the stretchable net when the aqueous liquid cosmetic is used, and on the other hand, the cosmetic does not pass through the mesh of the stretchable net when the aqueous liquid cosmetic is not used. While not being bound by theory, it is believed that the surface of the stretchable web that has been subjected to the water repellent treatment is hydrophobic, thereby impeding passage of the aqueous liquid cosmetic through the small mesh when the stretchable web is not in use.
By sufficiently reducing the mesh size when the stretchable net is stretched, the mesh size of the stretchable net is completely closed when the liquid cosmetic is not used (when the stretchable net is contracted), and the mesh size of the stretchable net can be opened by the stretching of the stretchable net when the liquid cosmetic is used.
The type of the water repellent treatment is not particularly limited, and examples thereof include: surface treatment with an arbitrary water repellent agent containing fluorine compound, silicone (polysiloxane), non-fluorinated hydrocarbon, and the like.

The liquid cosmetic container of the present invention may be provided with a lid, and the lid preferably covers the stretchable net. Thus, leakage of the aqueous liquid cosmetic from the container body can be more reliably avoided.
The liquid cosmetic container of the present invention may include an applicator such as a puff and a cosmetic pencil between the cover and the stretchable net. Thereby, the application operation can be easily performed when the aqueous liquid cosmetic is used.
Fig. 1 is an exploded perspective view showing an example of the liquid cosmetic container according to the present invention, and the liquid cosmetic container a shown in fig. 1 includes: a container body 1, a lid 2, a middle frame 3, a liquid cosmetic 4 containing water, a stretchable net 5, an applicator 6, and a sealing member 7.
In the example shown in fig. 1, the container body 1 is a substantially cylindrical dish-shaped member having one end closed to form a bottom and the other end opened, and has a storage portion for storing the aqueous liquid cosmetic 4 and an opening portion opening in the direction of the center 3.
The middle frame 3 is a substantially cylindrical member having an upper end opening and a lower end opening, and is accommodated in an accommodating portion of the container body 1 through the opening of the container body 1. Specifically, the outer diameter of the center 3 is equal to or smaller than the inner diameter of the container portion of the container body 1, a flange is formed to protrude from the upper end edge of the center 3 so as to be overlapped with the upper end edge of the opening of the container body 1, the center 3 is inserted into the container portion from the opening of the container body 1 until the lower surface of the flange abuts against the upper end edge of the opening of the container body 1, the flange is overlapped with the upper end edge, and the center 3 is fixed at a predetermined depth position in the container portion of the container body 1, and the aqueous liquid cosmetic 4 is stored in the lower portion of the center 3 in the container portion of the container body 1. Accordingly, in the example shown in fig. 1, the aqueous liquid cosmetic 4 and the center 3 are simultaneously stored in the storage portion of the container body 1. The upper end opening of the center 3 corresponds to the opening of the container body 1, and the aqueous liquid cosmetic 4 can be taken out from the outside.
An elastic net 5 is provided at any position between the upper end opening portion and the lower end opening portion of the middle frame 3. A stretchable net 5 may be provided at the lower end opening of the middle frame 3. The stretchable net 5 covers the opening of the middle frame 3 and also covers the opening of the container body 1.
The stretchable web 5 may be made of the above-described material, and may be subjected to the above-described waterproofing treatment.
The stretchable net 5 is deformable at least to the lower side (bottom direction) of the storage portion of the container body 1. By forming the stretchable web 5 from a material having high flexibility, the deformability of the stretchable web 5 can be improved.
The upper end opening of the center 3 is sealed by a sealing member 7. Thereby, the stretchable web 5 is isolated from the outside. The sealing member 7 is not particularly limited as long as it can seal the upper end opening of the middle frame 3, and for example, a metal laminate film having a releasable adhesive layer can be used.
The applicator 6 is accommodated in a space between the sealing member 7 and the lid 2. The form of the applicator 6 is not particularly limited, and for example, a puff or the like may be used.
The lid body 2 is also a substantially cylindrical member, and can be engaged with the container body 1 in a state where the applicator 6 is accommodated. Further, by engaging the lid 2 with the container body 1, the lid 2 can cover the stretchable net 5. Further, by engaging the lid 2 with the container body 1, the opening of the container body 1 can be closed.
In this way, the liquid cosmetic container a can hold and retain the aqueous liquid cosmetic 4.
When the aqueous liquid cosmetic 4 is used, the lid 2 is removed from the container body 1, the sealing member 7 is peeled off and removed to expose the stretchable net 5 to the outside, and then the applicator 6 is pressed against the stretchable net 5 by a finger or the like, so that the stretchable net 5 is deformed downward (in the bottom direction) of the storage portion of the container body 1, and only an appropriate amount of the aqueous liquid cosmetic 4 can be caused to float out of the mesh of the stretchable net 5. The aqueous liquid cosmetic 4 that emerges onto the surface of the stretchable web 5 is attached to the applicator 6.
Therefore, by pressing the applicator 6 against the stretchable web 5, the aqueous liquid cosmetic 4 can be attached to the applicator 6, and can be taken out from the container body 1 for use in cosmetic treatment of skin or the like. By the action of the stretchable web 5, an appropriate amount of the aqueous liquid cosmetic 4 adheres to the applicator 6, and thus it is possible to prevent the application of the aqueous liquid cosmetic 4 more than necessary to the skin.
