Description

  The present invention relates to a liquid cosmetic container that contains liquid cosmetics such as mascara, eyeliner, and eye shadow.

  A liquid cosmetic container for storing liquid cosmetics such as mascara generally has a container body for storing liquid cosmetics, a support shaft provided with a cosmetic application body, and a mouth portion of the container main body. There is known a liquid cosmetic container that includes a lid that closes the liquid and that is configured so that the cosmetic application body is immersed in the liquid cosmetic contained in the container body when the lid is closed. According to such a liquid cosmetic container, the liquid cosmetic adhering to the cosmetic application body (consisting of a brush or the like) can be applied to the eyelashes or the like.

  In addition, a squeeze member is generally provided on the inner peripheral portion of the mouth of the container body of the liquid cosmetic container to squeeze off the liquid cosmetic adhering to the cosmetic application body when the lid is attached or detached. The squeeze member generally includes a squirrel collar portion having a substantially conical cylindrical shape that is tapered downward and has a squeeze hole in the tapered portion. Using such a squealing member, the liquid cosmetics excessively attached to the cosmetic application body and the support shaft can be squeezed off by the squealing holes in the striated brim portion.

  Furthermore, a configuration is also known in which a collar-like expanded portion that expands a creaking hole in the closing process is provided on a support shaft (for example, see Patent Documents 1 and 2 below). According to the brim-shaped expansion portion, it is said that the positive pressure state inside the container body can be released because the hole can be expanded in the closing process. Moreover, according to the collar-shaped expansion part, the liquid cosmetic adhering to the inner peripheral part of the swordfish collar part is dropped from the squirrel hole and returned to the inside of the container main body by expanding the squirrel hole in the closing process. It is supposed to be possible.

However, even if the shigoki hole of the shigoki collar part is pushed out by the brim-like expanding part in the closing process, the shigoki hole is expanded as soon as the brim-like spreading part passes the shidoki hole. In many cases, the positive pressure state of the container body is not sufficiently released.
In recent years, high-viscosity liquid cosmetics (particularly mascara) have been used in order to enhance the volume-up effect and the curl-up effect. In a liquid cosmetic container containing such a high-viscosity liquid cosmetic, even if the bristle hole in the brim is expanded by the brim-like spread part, the liquid cosmetic is caused by the high viscosity. Thus, the liquid cosmetic adhering to the inner peripheral surface of the shigoki collar part is unlikely to fall from the shigoki hole.

  In other words, according to the liquid cosmetic container described in Patent Documents 1 and 2, when a highly viscous liquid cosmetic is accommodated, the positive pressure state inside the container body due to the collar-shaped expanded portion is released. And the effect of returning the liquid cosmetic to the inside of the container body cannot be sufficiently obtained.

  Accordingly, an object of the present invention is to reliably release the positive pressure state inside the container body and to reliably return the liquid cosmetic adhering to the inner peripheral surface of the scab collar to the inside of the container body. It is in providing the liquid cosmetic container which can be performed.

  The present invention includes a container main body for storing a liquid cosmetic, and a lid having a support shaft provided with the cosmetic application body and closing the mouth of the container main body, and the cosmetic application body when the lid is closed Is a liquid cosmetic container configured to be immersed in the liquid cosmetic contained in the container main body, and is attached to the cosmetic application body on the inner peripheral portion of the mouth of the container main body A squeeze member for squeezing off the liquid cosmetic material when the lid is attached and detached is provided, and the squeeze member has a substantially conical cylindrical brim portion that is tapered downward and has a crease hole in the tapered portion. And the support shaft is provided with an expansion member capable of expanding the squeeze hole in the closing process and maintaining the expanded state of the squeeze hole when the cover is closed. Achieving the above objectives by providing a container Than is.

  According to the liquid cosmetic container of the present invention, the positive pressure state inside the container body can be reliably released, and the liquid cosmetic adhering to the inner peripheral surface of the scab collar portion can be reliably put inside the container body. Can be returned.

Hereinafter, the liquid cosmetic container of the present invention will be described based on a preferred embodiment thereof with reference to the drawings.
FIG. 1 shows a longitudinal sectional view of the liquid cosmetic container of the present embodiment in a state where the container body and the lid are combined. FIG. 2 shows a longitudinal sectional view of the container body, and FIG. 3 shows a longitudinal sectional view of the lid.

The liquid cosmetic container 1 of the present embodiment has a container body 2 that contains the liquid cosmetic C, and a support shaft 41 provided with a cosmetic application body 42, as shown in FIGS. And a lid 3 that closes the mouth portion 22 of the main body 2, and the cosmetic applicator 42 is configured to be immersed in the liquid cosmetic C accommodated in the container main body 2 when the lid is closed. Further, the inner peripheral portion of the mouth portion 22 of the container body 2 is provided with a squeeze member 5 that squeezes off the liquid cosmetic C adhering to the cosmetic application body 42 when the lid 3 is attached and detached.
Below, the liquid cosmetic container 1 of this embodiment is explained in full detail.

As shown in FIG. 2, the container main body 2 is formed in a substantially cylindrical shape with a bottom, and includes a container 21 for the liquid cosmetic C, a mouth 22 opened at the upper part thereof, and a lower part from the mouth 22. And a connecting portion 23 extending in the direction.

The connecting portion 23 is formed integrally with the mouth portion 22 and is fitted to the upper portion of the inner peripheral portion of the storage portion 21 via a squeeze body 53 and a squeeze fitting portion 52 (details will be described later) of the squeeze member 5. It is a part to match. The lower part of the outer peripheral part of the connection part 23 is constricted, and the space | gap where the squeeze fitting part 52 is fitted is formed between the outer peripheral part of the connection part 23, and the inner peripheral part of the accommodating part 21. FIG.

In the container body 2, liquid cosmetics C such as mascara, eyeliner, and eye shadow are accommodated.
The liquid cosmetic is not particularly limited, but the liquid cosmetic container of the present invention is preferably used as a container for storing a high-viscosity liquid cosmetic. For example, in the case of mascara, the viscosity of the liquid cosmetic is usually 100,000 mPa · s or more, and there is also one having a viscosity of 300,000 mPa · s or more.

When the viscosity of the liquid cosmetic is 10,000 to 100,000 mPa · s, use “B-type viscometer: B8L, rotor: No. 4, rotation speed: 6 rotations (manufactured by Tokimec Co., Ltd.)” In the case of 100,000 to 800,000 mPa · s, “B-type viscometer (helical type): B8R, spindle: TD, rotation speed: 5 rotations (manufactured by Tokimec Co., Ltd.)” is used. Measure in a ℃ environment.
The liquid cosmetic may be semi-solid as long as it has fluidity that can be applied to the cosmetic application body 42 and applied.

  If the liquid cosmetic C contains volatile hydrocarbon oils such as low-boiling light liquid isoparaffin and isododecane, the high volatility reduces the stickiness after use and improves the feeling of use. . Among volatile hydrocarbon oils, examples of low boiling light liquid isoparaffin products include IP solvent (manufactured by Idemitsu Chemical Co., Ltd.), Isopar (manufactured by Shell Co.), and isosol (manufactured by Nippon Petrochemical Co., Ltd.). A product of isododecane is Marcazole R (manufactured by Maruzen Petrochemical Co., Ltd.). Above all, it is preferable to use isododecane from the point of smell and feeling of use. Low boiling light liquid paraffin and isododecane can be combined with other oils. Although the oil agent to be combined is not particularly limited, volatile silicone or a low viscosity oil agent having a viscosity of about 15 mPa · s is preferable.

  Further, when the film-forming polymer emulsion is contained in the liquid cosmetic C, there is an effect of further improving the makeup holding and the volume feeling. Examples of such film-forming polymer emulsions include homopolymer emulsions and copolymer emulsions of alkyl esters of acrylic acid and methacrylic acid, alkyl acrylate / styrene copolymer emulsions, polyvinyl acetate polymer emulsions, and silicone polymer emulsions. It is done. In particular, an alkyl acrylate copolymer emulsion is preferred.

  The material of the container body 2 is not particularly limited. For example, the storage portion 21 is made of an aluminum alloy, and the mouth portion 22 and the connecting portion 23 are made of polypropylene (PP). Moreover, when a liquid cosmetic contains the volatile hydrocarbon oil mentioned above, the material which does not swell by it is used preferably. An example of such a material is polyethylene terephthalate (PET).

The squeeze member 5 is a member that squeezes off the liquid cosmetic C adhering to the cosmetic application body 42 when the lid 3 is attached / detached, and as shown in FIG. 2, the squirrel body 53, the squirrel brim part 51, and the squirrel fitting part. 52.
The shigoki body 53 is a part inscribed in the inner peripheral part of the connection part 23 of the container body 2. The shigoki body 53 has, for example, a substantially cylindrical shape with an upper part and a lower part opened.

The sword collar 51 is a “rib-shaped part” that comes into contact with the cosmetic applicator 42 and is formed in a substantially conical cylindrical shape that extends inward and downward from the upper edge of the squirrel body 53. In the tapered portion, a side hole 51A is formed. The diameter of the side holes 51 </ b> A is set smaller than the outer diameters of the cosmetic application body 42 and the support shaft 41. With this configuration, the shigaki collar 51 elastically adheres to the outer peripheral surface of the cosmetic applicator 42 and the support shaft 41 at the inner peripheral edge portion of the shigaki hole 51A.
The cross-sectional shape and cross-sectional area (diameter) of the squeeze hole 51A are appropriately set according to the cross-sectional shape, cross-sectional area, material, rigidity, required squeeze performance of the cosmetic application body 42 and the support shaft 41, and the like.

The squirrel fitting portion 52 is a portion that fits between the inner peripheral portion of the storage portion 21 of the container main body 2 and the outer peripheral portion of the connecting portion 23, and the lower end edge from the inner peripheral portion of the connecting portion 23 of the container main body 2. It has a cross-sectional shape over the outer periphery via In the present embodiment, the squeeze fitting part 52 is sandwiched and fitted in a gap between the lower part of the outer peripheral part of the connecting part 23 and the inner peripheral part of the storage part 21.
As a result, the storage portion 21 and the connecting portion 23 are fixed via the squeeze fitting portion 52. Further, the swordfish main body 53 is fixed in contact with the inner peripheral part of the connecting part 23 via the squirrel fitting part 52, and the squirrel collar part 51 is tapered from the upper end edge of the squirrel body 53 toward the inside and downward. In other words, it is fixed to the lower end edge of the inner peripheral portion of the mouth portion 22 so as to form a tapered shape from the lower end edge of the inner peripheral portion of the mouth portion 22 toward the inner lower side.

  In the present invention, “the squealing member 5 is provided on the inner peripheral portion of the mouth portion 22 of the container body 2” is determined based on the scouring brim 51, and the squirting brim 51, as in this embodiment. A part other than the above, specifically, a form in which the body part 53 and the body fitting part 52 are not located on the inner peripheral part of the mouth part 22 of the container body 2 is included.

Although the raw material of the squeal member 5 is not particularly limited, it is made of, for example, nitrile rubber (NBR rubber) or polybutylene terephthalate copolymerized with soft segments (hereinafter also referred to as “soft PBT”).
Soft PBT is obtained by copolymerizing a soft segment with polybutylene terephthalate (PBT). Polybutylene terephthalate is known as a plastic material having excellent oil resistance. However, since it has a high flexural modulus and is a hard material like PET, it is not suitable for use as a material for the squeeze member 5. On the other hand, PBT can be copolymerized with a resin having specific flexibility to form a soft PBT copolymerized with a segment (soft segment) that imparts flexibility.

  Soft PBT constitutes a plastic material having a low flexural modulus without changing the main physical properties of PBT. The bending elastic modulus is, for example, 300 to 2400 MPa, preferably 300 to 900 MPa. As the flexible resin copolymerized with PBT, for example, polyol diol and the like can be used, and the flexural modulus can be appropriately adjusted by adjusting the blending amount thereof. Specific examples of the soft PBT include a trade name “Novaduran 5500 Series” (manufactured by Mitsubishi Engineering Plastics Co., Ltd.).

  Next, the lid 3 will be described. As shown in FIG. 3, the main body (lid body) 31 of the lid 3 has a substantially cylindrical shape with a top surface and an open bottom, and has a design that is integral with the container body 2 when the lid is closed. doing. A female screw portion 34 that is screwed with the male screw portion 24 of the mouth portion 22 of the container main body 2 is formed at the lower portion of the inner peripheral portion 32 of the lid body 31. The lid 3 (lid body 31) is fixed to the mouth portion 22 of the container body 2 when the lid is closed by screwing the female screw portion 34 and the male screw portion 24 together. The lid body 31 is made of, for example, polypropylene (PP).

As shown in FIG. 3, the cosmetic application member 4 constitutes a part of the lid 3, and includes a support shaft 41, a cosmetic application body 42, a spread member 6, and a fixing portion 44.
The fixing portion 44 is a portion that is fitted and fixed to the upper portion of the inner peripheral portion 32 of the lid 3.
The support shaft 41 is a shaft that supports the cosmetic application body 42, and is fixed to the inner peripheral portion 32 of the lid 3 via a fixing portion 44.
The material of the support shaft 41 is not particularly limited, and examples thereof include polypropylene (PP). Moreover, when a liquid cosmetic contains the volatile hydrocarbon oil mentioned above, the material which does not swell by it is used preferably. An example of such a material is PBT.

The cosmetic application body 42 is provided at the tip (lower end) of the support shaft 41, and the liquid cosmetic C attached to the cosmetic application body 42 is applied to the application object (if the liquid cosmetic C is mascara, eyelashes). ) Can be applied.
The material of the cosmetic applied body 42 is not particularly limited, but when the liquid cosmetic contains the volatile hydrocarbon oil described above, a material that does not swell by that is preferably used. Examples of such a material include a brush mainly made of nylon (nylon brush).

The expansion member 6 is provided on the support shaft 41, and is configured to expand the squeeze hole 51A during the closing process and to maintain the squeezed condition of the squeeze hole 51A when the cover is closed.
In the present embodiment, the expansion member 6 is provided between the cosmetic applicator 42 and the fixing portion 44 in the support shaft 41, and uses the through-hole penetrating in the vertical direction to support the support shaft 41. The small diameter portion 41A is fitted. The push-spreading member 6 is inserted from the lower end side of the support shaft 41 and fitted into the small-diameter portion 41A in a state where the through hole is extended in the radial direction before attaching the cosmetic application body 42 to the support shaft 41. be able to.
Although the material of the expansion member 6 is not particularly limited, the same material as the squeak member 5 is preferably used.

The expansion member 6 includes a first expansion portion 61 at a lower portion and a second expansion portion 52 at an upper portion, and a constricted portion 63 that is narrower than the both expansion portions 61 and 62 between the expansion portions 61 and 62. have.
The first expanded portion 61 is a “collar-shaped portion” provided to extend outward from the lower portion of the expanded member 6. The first expanded portion 61 has an outer peripheral shape that is slightly larger than the squeeze hole 51A of the squeeze collar 51 of the squeeze member 5. Therefore, in the closing process, the squeeze collar 51 is pressed downward, The side holes 51A of the collar portion 51 can be expanded. The first expanded portion 61 in the present embodiment has a sharp outer end.

  Further, the expansion member 6 is configured to maintain the expanded state of the side hole 51A when the lid is closed by the outer peripheral portion of the bulged second expansion portion 62. Specifically, the second expanded portion 62 is a portion provided on the upper portion of the expanded member 6, and the outer peripheral portion of the second expanded portion 62 bulges outward and downward. It has a shape that is slightly larger than the shape of the inner peripheral portion of the shigoki collar portion 51. Moreover, the outer peripheral part of the 2nd expansion part 62 has a slightly larger shape than the shape of the inner peripheral part of the mouth part 22 of the container main body 2.

  Therefore, the outer peripheral portion of the bulging second expanded portion 62 can press the shigura collar 51 downward in the lid closing process to expand the shimoki hole 51A of the shigaki collar 51, and at the time of lid closing. Even in the (completely closed state), the shigori collar 51 is pressed downward, and the shigori hole 51A can be maintained in an expanded state. Here, “the state in which the side holes 51A are expanded” refers to a state in which the peripheral portion of the side holes 51A is separated from the cosmetic application member 4 (in the present embodiment, the expansion member 6).

  Further, in the lid closing process, the bulging outer peripheral portion of the second push-out portion 62 is in close contact with the inner peripheral portion of the swordfish collar portion 51 and the inner peripheral portion of the mouth portion 22 of the container body 2. The liquid cosmetic adhering to the inner peripheral part of 51 and the inner peripheral part of the mouth part 22 of the container main body 2 can be scraped off. When the outer peripheral portion of the second expanded portion 62 comes into contact with the inner peripheral portion of the brim collar portion 51 and the inner peripheral portion of the mouth portion 22 of the container body 2, the liquid cosmetic is scraped off. The effect is particularly excellent.

  In the cosmetic application member 4, the cosmetic application body 42 is positioned below the opening at the bottom of the lid body 31, so that, as shown in FIG. 1, the cosmetic application body 42 is applied when the lid is closed. The body 42 is immersed in the liquid cosmetic C accommodated in the container body 2.

  As shown in FIG. 1, a packing 33 is provided in a portion of the lid 3 that comes into contact with the upper edge of the mouth portion 22 of the container body 2 when the lid 3 is closed. The packing 33 improves the airtightness between the container body 2 and the lid 3 when the lid is closed. In the present embodiment, the packing 33 is made of, for example, nitrile rubber (NBR rubber), and is fitted into a small-diameter portion below the fixed portion 44.

Next, one usage method of the liquid cosmetic container 1 of this embodiment is demonstrated, and the effect | action and effect of the liquid cosmetic container 1 of this embodiment are also demonstrated collectively.
First, the squeaking action of the liquid cosmetic C attached to the cosmetic application body 42 by the squeaking member 5 will be described.

  As shown in FIG. 1, FIG. 4 (a) and FIG. 4 (b), when the lid 3 is removed upward from the container body 2 from the closed state, the cosmetic application member 4 is also moved upward accordingly. . At that time, the outer peripheral surface of the support shaft 41 and the cosmetic applicator 42 are squeezed in order by the support collar portion 51 of the support member 5. As a result, the liquid cosmetic C excessively adhered to the cosmetic application body 42 and the support shaft 41 is squeezed off, and an appropriate amount of the liquid cosmetic C is adhered. Using the cosmetic application body 42 in such a state, the liquid cosmetic C can be applied to an application target (eyelashes when the liquid cosmetic C is mascara).

  Further, the amount of the liquid cosmetic C attached to the cosmetic applied body 42 decreases, and when the liquid cosmetic C is attached again to the cosmetic applied body 42 or when the lid 3 is attached to the container body 2 after use. 4 (b), 4 (a) and 4 (c), the outer peripheral surface of the cosmetic applicator 42 and the support shaft 41 in this order by the squirrel collar portion 51 of the squeeze member 5. I'm crushing. Thereby, the liquid cosmetic C adhering to the cosmetic application body 42 and the support shaft 41 is rubbed off.

  Here, the liquid cosmetic C adhering to the cosmetic application body 42 and the support shaft 41 is, as shown in FIG. 4 (b), in the attaching / detaching operation of the lid 3, Adhere to the outer periphery. The liquid cosmetic C adhering to the outer periphery of the scab collar 51 falls naturally by its own weight and returns to the storage unit 21 of the container body 2. On the other hand, the liquid cosmetic C adhering to the inner peripheral portion of the scab collar 51 is substantially sealed with the support shaft 41 or the cosmetic application body 42 when the viscosity of the liquid cosmetic C is high. (The swordfish collar 51 may be separated from the support shaft 41 or the cosmetic application body 42, but the time is extremely short), and therefore it does not fall from the squirrel hole 51A and is almost in the storage part 21 of the container body 2. Dont return.

  Next, the positive pressure releasing action inside the container body 2 by the first and second expanding parts 61 and 62, and the liquid cosmetic adhering to the inner peripheral part of the shigaki brim part 51 by the second expanding part 62. The scraping action of C will be described.

  4 (b), 4 (a), and 4 (c), the lid 3 is moved closer to the container body 2 from the open state, and the cosmetic applicator 42 and the support shaft 41 are squeezed. The cosmetic applied body 42 and the support shaft 41 enter the liquid cosmetic C when the member 5 is inserted into the side hole 51A. Along with this, the liquid level of the liquid cosmetic C rises by the volume of the infiltrated portion. Therefore, the inside of the storage part 21 of the container main body 2 sealed by the shigaki brim part 51 and the support shaft 41 is pressurized to be in a positive pressure state.

  However, in the lid closing process, as shown in FIG. 4C and FIG. 1, the first pushing and expanding portion 61 presses the shigaki collar 51 downward and pushes the shigori hole 51 </ b> A to the shigoki collar 51. Move down. For this reason, although it is a short time, the peripheral edge portion of the squeeze hole 51 </ b> A is separated from the push-expansion member 6 (the constricted part 63), and a communication path is formed between the squirrel brim part 51 and the push-expansion member 6. As a result, the positive pressure air inside the container body 2 is discharged upward through the communication path, and the inside of the container body 2 is decompressed.

In addition, when the shigo hole 51A is expanded by the first expanding portion 61 and a communicating path is formed between the shiki collar 51 and the expanding member 6 (the constricted portion 63), the communicating path is interposed through the communicating path. Thus, the liquid cosmetic C adhering to the inner peripheral portion of the shigoki collar portion 51 can fall from the shigoki hole 51A and return to the inside of the container body 2.
However, when the first expanded portion 61 passes through the hole 51A, the hole 51A tends to shrink immediately. If the brim brim portion 51 and the expansion member 6 (narrow portion 63) are in close contact with each other, especially when the viscosity of the liquid cosmetic material C is high, the liquid cosmetic material C passes through the communication path to the container body 2. As a result, the liquid cosmetic C adhering to the inner peripheral part of the scab collar 51 may hardly remain there.

  Thus, according to the liquid cosmetic container 1 of the present embodiment, as shown in FIG. 4C and FIG. 1, the second expanding portion 62 of the expanding member 6 bulges in the closing process. By the outer peripheral portion, the brim collar 51 is pressed again downward, and the bristle hole 51A is expanded to form the communication path, and the squeeze hole 51A is expanded when the lid is closed (the communication path is The formed state) is maintained. As described above, since the communication path formed between the brim brim 51 and the expansion member 6 is maintained by the second expansion part 62, the positive pressure state inside the container body 2 is reliably released. . In addition, the liquid cosmetic C adhering to the inner peripheral portion of the brim collar portion 51 is scraped off by the outer peripheral portion of the second expanded portion 62 and is reliably returned to the inside of the container body 2.

The liquid cosmetic container of the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the gist of the present invention.
For example, the expansion member 6 is configured separately from the support shaft 41 in the above embodiment, but can be formed integrally with the support shaft 41 in the present invention.
In the above-described embodiment, the expansion member 6 includes two expansion portions (a first expansion portion 61 and a second expansion portion 62). In the present invention, the squeeze hole 51A is used in the closing process. If the state where the squeeze hole 51A is expanded when the lid is closed can be maintained, it can be configured to include only one expanded portion.

The shapes of the brim brim portion 51 of the shigoki member 5 and the first expanded portion 61 and the second expanded portion 62 of the expanded member 6 are not limited to the shapes in the above embodiment.
The 2nd expansion part 62 of the expansion member 6 is comprised so that it may closely_contact | adhere to the inner peripheral part of the brim part 51 of the squeeze member 5, and the inner peripheral part of the mouth part 22 of the container main body 2 in the said embodiment. However, in this invention, you may be comprised so that it may closely_contact | adhere only to any one internal peripheral part, and you may be comprised so that it may not closely_contact | adhere to both internal peripheral parts.

The squeeze member 5 may be formed integrally with a part or all of each member (the storage part 21, the mouth part 22, the connection part 23) constituting the container body 2.
As long as at least the liquid cosmetic adhering to the cosmetic application body 42 can be squeezed out, the shigoki member 5 may not be able to squeeze out the liquid cosmetic adhering to the support shaft 41.
The shape, position, and the like of the brim collar portion 51 of the squeak member 5 are not limited to the shape, position, and the like in the embodiment. For example, the brim collar portion 51 may have a discontinuous shape in plan view, and may be provided above the lower end edge of the mouth portion 22.
