Liquid cosmetic container

  The present invention relates to liquid cosmetic containers such as mascara, eyeliner, and lip gloss. More specifically, the present invention relates to an applicator provided at the tip of an application bar that hangs down from a ceiling portion of a cap, the application bar, and a wiper that wipes off excess liquid cosmetic material adhering to the applicator.

Conventionally, liquid cosmetics such as mascara, eyeliner, lip gloss and the like are attached to an applicator provided at the tip of the application bar, and an appropriate amount of liquid cosmetic is applied to the eyelashes, eyelashes, lips. Etc. The liquid cosmetic taken out from the container main body was excessively provided at the neck of the container main body and squeezed with a wiper that formed an insertion hole having a slightly smaller diameter than the outer periphery of the applicator, and returned to the container main body.

  Liquid cosmetic containers are mainly carried away in handbags or stored in drawers or the like on a dressing table, and the container posture is rarely arranged properly. Therefore, the wiper is required to have a packing function that can prevent inadvertent leakage of the liquid cosmetic from inside the container body. On the other hand, the wiper is required to have a function of avoiding the ejection of cosmetics and the pumping phenomenon of the coating rod accompanying the increase in internal pressure when the coating rod is inserted into and removed from the container body.

  Further, the applicator has been required to be able to sufficiently adhere the liquid cosmetic material in the container body to the brush hair and to easily adjust the removal amount.

Japanese Utility Model Publication No. 57-179313 (first page, FIG. 2, FIG. 3) Japanese Patent Laying-Open No. 2004-187878 (7th page, FIGS. 1 and 2) Japanese Patent Laying-Open No. 2008-23013 (6th page, FIGS. 1 and 4)

Patent Document 1 and Patent Document 2 prevent inadvertent leakage of liquid cosmetics regardless of the attitude of the container body, and the ejection of cosmetics accompanying the increase in internal pressure when the application rod is inserted into and removed from the container body. The means for avoiding the pumping phenomenon of the coating rod is illustrated.

That is, in Patent Literature 1, a wiper ( wiping rubber piece) is provided on the inner periphery of the neck of the container body, and the wiping portion and the wiping are provided with an air vent hole formed in the side wall so that the tip side is slidably in contact with the coating rod and the increase in internal pressure is suppressed. It is comprised from the skirt part drooping from the upper outer wall of a part. The applicator bar is provided with an enlarged diameter step on the upper side, and when the insertion of the applicator bar is completed, the wiping part is expanded to close the air vent and prevent the liquid cosmetic from being inadvertently leaked.

Further, in Patent Document 2, a wiper (scraping member) is provided on the inner periphery of the neck (mouth neck) of the container body, the tip is in sliding contact with the application rod (shaft) , and liquid cosmetic is placed on the outer periphery in the container body. It consists of a scraping collar portion having a liquid passage hole to be returned. The liquid passage hole has a function of an air vent hole that solves the problem of liquid cosmetics remaining on the wiper (scraping member) when the application shaft is inserted and removed, and suppresses an increase in internal pressure in the container body. The extrusion member projecting from the extruded flange portion having elasticity to the upper outer provided the coating rod (shaft), inadvertent leakage of closing the liquid passage holes upon completion of insertion of the coating rod (shaft) liquid cosmetic To prevent.

  The air vent hole in Patent Document 1 and the liquid passage hole in Patent Document 2 can prevent an increase in internal pressure and leakage of liquid cosmetics when not in use. However, when the liquid cosmetic is agitated by inserting / removing the coating rod into / from the container body, the liquid cosmetic continues to expand due to foaming because air related to foaming is supplied from the outside through the air vent hole and liquid passage hole. Therefore, the problem of liquid cosmetic eruption has not been solved.

Furthermore, when the cap was opened even a little, leakage of the liquid cosmetic could not be prevented. For example, the liquid cosmetic that is attached to the outer periphery of the application rod in the container body and pulled up is foamed and expands, and leaks through the air vent hole and the liquid passage hole. The leaked liquid cosmetic accumulates on the wiper provided on the inner circumference of the neck of the container body, and newly adheres the liquid cosmetic to the surface of the application bar just squeezed with the wiper, and stains the surroundings and fingers during makeup. There was a problem.

  Patent Document 3 is an applicator in which brush hairs are arranged in a band shape, and exemplifies an applicator that adheres liquid cosmetics sufficiently to the brush hair and is easy to use by application to eyelashes, eyelashes, lips, and the like. .

Patent Document 3 is an applicator in which a band-shaped application portion is disposed along the bottom surface of a groove provided on the application rod, and when the applicator is rubbed with a wiper (ironing piece) , the brush hair is the bottom of the groove . Is bent and bent over the hair tip and stored in the groove. Since liquid cosmetics also accumulate in the groove at the same time, liquid cosmetics can be evenly adhered from the tip of the brush hair to the root even after being wiped with a wiper (squeezing piece) , and at the same time, other than the application part It makes it possible to wipe off the outer circumference of the rod completely.

  However, even when the applicator of Patent Document 3 is applied to a liquid cosmetic container using a conventional wiper, there is a problem that leakage of the liquid cosmetic cannot be prevented.

  The present invention has been made in view of such problems, and the object of the present invention is to provide a liquid makeup that is easy to use by eliminating leakage and ejection of liquid cosmetics such as foamed mascara from the container body. It is intended to provide a food container.

  Another object of the present invention is to provide a cosmetic applicator in which applicators are arranged in a strip shape extending linearly in the axial length direction and can be applied to the eyelashes without failure. It is another object of the present invention to provide a liquid cosmetic container having a cosmetic applicator to which the liquid cosmetic adhering to the applicator adheres evenly to the tip of the brush hair. In addition, such a liquid cosmetic container can be provided at low cost.

In the liquid cosmetic container according to the present invention, the wiper 5 forms a funnel-like portion 55 whose diameter increases toward the neck entrance of the container body 1 to achieve the above object, and slides the entire circumference of the application bar 7 and applies the application bar. 7 has an insertion hole 51 through which the 7 can be inserted, and a plurality of slits 53 penetrating the front and back so as to intersect the extending direction of the wiper 5 .

The applicator bar 7 has a large-diameter portion 71 that is in close contact with the funnel-like portion 55 at the closed position of the cap 3 .

Further applicator 9, the applicator base 91 provided at the tip of the coating rod 7, the concave groove 93 provided in parallel to the front to the coating rod 7 of the applicator base 91, Ryakushide from the bottom 92 of the groove 93 The brush bristles 95 are provided.

The cosmetic applicator of the present invention has the following effects. That is, a slit 53 that penetrates the front and back of the wiper 5 is open at the insertion of the container main body 1 inside of the coating rod 7 is closed by disengaged to the container body 1 out of the coating rod 7. The opening of the slit 53 makes the pressure in the container body 1 equal to that of the outside air and prevents the pressure from rising. Further, the blockage of the slit 53 blocks the movement of the air and the liquid cosmetic 100 inside and outside the container body 1 .

Increasing the total amount of the liquid cosmetic 100 and the air amount of the opening and closing the liquid cosmetics 100 coating bar 7 in the container body 1, the container body 1 even when bubbles 110 are stirred occurs by applicator 9 or the like of the slit 53 I won't let you. Therefore the container body 1 within bubbles 110 laden liquid cosmetic 100 container body 1 of the liquid cosmetic 100 apparently not be increased than the volume, the cause of the ejection and leakage is eliminated container body 1 or more volume increase There is an effect to be eliminated.

Further, the clogging of the slit 53 eliminates the outlet of the liquid cosmetic 100 that is attached to the outer periphery of the application bar 7 and pulled up. Accordingly, there is an effect of preventing leakage of the liquid cosmetic material 100 and suppressing liquid accumulation on the inner surface side of the wiper 5 .

The large-diameter portion 71 formed on the application rod 7 closes the opening of the slit 53 by being in close contact with the funnel-shaped portion 55 at the closed position of the cap 3 . Closure of the slit 53 by the large-diameter portion 71 of the application bar 7 returns the liquid cosmetic 100 adhering to the inner surface of the wiper 5 into the container body 1 . Furthermore, leakage of the liquid cosmetic 100 due to the posture of the liquid cosmetic container with the cap 3 closed can be prevented. Therefore, there is an effect that the applicator 9 attached to the always clean application bar 7 can concentrate on makeup with peace of mind.

Also, completely wipe the coating rod 7 circumference liquid cosmetic 100 by the coating rod 7 regardless protruding shape of the bristles 95 by the bristles 95 is pushed into the groove 93 by sliding contact pressure of the wiper 5 it can. At the same time, the liquid cosmetic 100 is distributed uniformly along with the bristle 95 in the concave groove 93 . Therefore, when the applicator 9 returns to its shape, the brush bristles 95 have an effect that the liquid cosmetic 100 can be evenly attached to the tip and coating unevenness can be eliminated.

It is insertion / removal explanatory drawing of the application | coating stick | rod concerning this invention. It is explanatory drawing of one Example of the applicator concerning this invention. It is extraction explanatory drawing of the applicator in a container main body.

The wiper 5 has a funnel-shaped portion 55 , and a plurality of slits 53 penetrating the front and back are formed in the funnel-shaped portion 55 . When the applicator 9 or the applicator bar 7 is inserted into the container body 1 in which the liquid cosmetic 100 is stored, the funnel-like portion 55 extends and the slit 53 opens. Further, when the applicator 9 or the applicator bar 7 is removed from the container body 1 , the funnel-shaped portion 55 is compressed and reduced and closed. Accordingly, the wiper 5 is required to have tear strength and stretchability. As the wiper material, for example, NBR rubber, silicon rubber, urethane rubber or the like is preferably used.

The applicator 9 is an applicator provided at the tip of the applicator bar 7 to apply and apply the liquid cosmetic 100 in the container body 7. The applicator 9 is recessed in front of the applicator base 91 so as to be parallel to the central axis L of the applicator bar 7. A groove 93 is formed. A bristle 95 having soft elasticity is suspended from the bottom 92 of the concave groove 93 . The concave groove 93 uniformly accommodates the brush hair 95 and the liquid cosmetic 100 when the liquid cosmetic 100 in the container body 1 is attached and squeezed by the wiper 5 . Therefore, the concave groove 93 has a space for storing the bent brush hair 95 and further storing the liquid cosmetic 100 necessary for application. The applicator 9 may be formed by integrally forming the applicator base 91 and the brush bristles 95 and further integrally formed with the application bar 7 . In this case, at least the brush bristles 95 are bent by the wiper 5 and bent so that the applicator material is elastic enough to be stored in the concave groove 93 .

  Hereinafter, the liquid cosmetic container of the present invention will be described with reference to the drawings. FIG. 1 is an assembly explanatory view of a mascara container using the cosmetic applicator of the present invention, and represents a longitudinal sectional view of a mascara container which is an example of a liquid cosmetic container.

In the figure, the liquid cosmetic container is composed of a cylindrical container main body 1 that contains the liquid cosmetic 100 and a cap 3 that is screwed onto the container main body 1. A coating rod 7 having a substantially circular cross section and having an applicator 9 at the lower end is suspended from the inner ceiling of the cap 3. The liquid cosmetic 100 is attached to and removed from the applicator 9 from the container body 1, and is applied while holding the cap 3 with a fingertip. Therefore, the application bar 7 is set to a length that is easy to apply by holding with fingers. An enlarged large diameter portion 71 is provided at an intermediate position of the application rod 7.

A neck tube 11 having a male screw portion 13 is fitted to the upper opening end of the container body 1. A wiper 5 is fixed between the lower portion of the neck tube 11 and the container body 1. The wiper 5 has a funnel-like portion 55 having a slit 53 penetrating the front and back and an insertion hole 51 that spreads upward and is slidably contacted with the outer circumference of the application rod 7 and the applicator base 91 that pass through the insertion hole 51. The cosmetic 100 is wiped off.

  Further, the large diameter portion 71 provided at the intermediate position of the application bar 7 closes the opening of the slit 53 of the funnel-shaped portion 55 forming the wiper 5 at the position where the container body 1 is closed.

  Since the applicator 9 and the application stick 7 in which the liquid cosmetic material 100 remains are inserted into and removed from the wiper 5, the inner surface of the wiper 5 is soiled and funnel-shaped even if the liquid cosmetic material 100 is not leaked or ejected from the container body 1. A liquid pool may be formed on the inner surface of the portion 55. The large diameter portion 71 forcibly returns the liquid cosmetic 100 adhering to the inner surface of the wiper 5 through the opening of the slit 53 of the funnel-shaped portion 55 forming the wiper 5 into the container body 1.

  Further, when the container body 1 is closed with the cap 3, the slit 53 may not be completely closed. However, the large-diameter portion 71 can completely close the slit 53 that is opened, and prevents the liquid cosmetic 100 from leaking onto the wiper 5 due to the attitude of the container body 1.

  FIG. 2 is an explanatory view of a wiper according to the present invention. In FIG. 2A, the application bar 7 is inserted in the direction of arrow A. An insertion hole 51 having a smaller diameter than the coating rod 7 is opened below the funnel-shaped portion 55 constituting the wiper 5. The wiper 5 in which the application bar 7 is inserted in the direction of arrow A, which is the direction of insertion of the application bar, extends the funnel-shaped portion 55 in the direction of arrow A, opens the slit 53, and moves the air in the container body 1 along the arrow C. Allow discharge.

  FIG. 2B shows a state where the application bar 7 is removed in the direction of arrow B, which is the direction of removal of the application bar. The wiper 5 from which the application rod 7 has been removed in the direction of arrow B compresses and reduces the funnel-shaped portion 55 in the direction of arrow B to strongly close the slit 53 and block air movement inside and outside the container body 1.

  FIG. 3 is an explanatory drawing of insertion / removal of the application bar according to the present invention. 3A, the funnel-shaped portion 55 of the wiper 5 is extended as shown in FIG. 2A, and the slit 53 is opened. The air in the container body 1 is pushed out by inserting the application bar 7 and is discharged according to the arrow D through the opened slit 53. Therefore, the pressure rise in the container body 1 is prevented.

  Next, the removal of the application bar 7 in the direction of arrow B shown in FIG. 3B compresses the funnel-shaped portion 55 of the wiper 5 as shown in FIG. The volume of the container body 1 is increased by removing the application bar 7, and external air is replenished and reduced by the closed slit 53. That is, the sum of the air in the container body 1 and the liquid cosmetic when the application bar 7 is inserted is kept constant regardless of whether the application bar 7 is inserted or removed by stirring or the like.

That is, the amount of air taken into the liquid cosmetic material 100 by stirring is the same as the amount of air in the container body 1 when the application bar 7 is inserted. Therefore, as shown in FIG. 3B, the apparent volume of the liquid cosmetic 100 in which the bubbles 110 are generated is less than the volume of the container body 1, and no matter how much the liquid cosmetic 100 is stirred, the liquid cosmetic 100 may be spouted or leaked. Disappear.

  Further, the liquid cosmetic material 100 adhering to the surface of the application bar 7 is forcibly pulled up toward the wiper 5 by the removal of the application bar 7. However, the liquid cosmetic 100 is prevented from leaking to the inner surface of the wiper 5 by the slit 53 closed as shown in FIG.

  Next, a description will be given of the ironing of the liquid cosmetic adhering to the applicator 9 that is optimal for using the wiper 5 according to the present invention.

  FIG. 4 is an explanatory view of an embodiment of the applicator according to the present invention. 4 is an applicator 9 fitted and fixed to the tip of an application bar 7 suspended from the inner ceiling of the cap 3 as shown in FIGS. 1 and 3, and FIG. FIG. 4B shows a bottom view seen from the comb portion 97 side. The applicator 9 shown in FIG. 4 is integrally formed with an applicator base 91, a groove 93, brush bristles 95, a comb 97, and an application bar attachment portion 99. The bristle 95 needs to be soft enough to be bent toward the concave groove 93 by the wiper 5. On the contrary, the applicator base 91 is required to have appropriate rigidity. In order to satisfy such conflicting hardness requirements, the ribs forming the concave grooves 93 are effective.

FIG. 5 is an explanatory drawing for extracting the applicator from the container main body when it is integrated with the application bar. As shown in FIG. 3 ( B ), a state in which the application bar 7 is removed in the direction of arrow B is partially displayed. Bristles provided vertically on the bottom 92 of the groove 93 95 enters the gap between the groove 93 as shown in FIG. 5 (A) by bending the sliding contact with the funnel-shaped portion 55 of the wiper 5.

  FIG. 5B shows an EE cross section of FIG. As shown in FIG. 5 (B), the liquid cosmetic 100 also uniformly enters the concave groove 93 together with the brush hair 95 that is slidably contacted with the funnel-like portion 55 of the wiper 5 and bent to enter the gap of the concave groove 93. Thus, even if the liquid cosmetic 100 that has entered the concave groove 93 is strongly rubbed with the wiper 5, it cannot be rubbed off.

However, the bristles 95 that have passed through the through-hole 51 of the wiper 5 are released from bending, and return to the shape while lightly contacting the funnel-shaped 55 portion and the inner surface of the neck tube 11 as shown in FIG.

When the applicator 9 is pulled out and wiped away from the wiper 5 in the direction of arrow B, the brush bristles 95 are greatly bent from the bottom 92 of the groove 93 to the bristles. Therefore, the bristle 95 can enter the concave groove 93 with a small force. The applicator base 91 that accommodates the brush hair 95 in the concave groove 93 is used to wipe off the liquid cosmetic 100 adhering to the surface by the wiper 5. However, the liquid cosmetic 100 remains in the concave groove 93 of the application rod 7. Therefore, in the gap between the adjacent bristle hairs 95 whose shape has been restored, the liquid cosmetic 100 that has entered between the bristle hairs 95 is attached and held between the bristle hairs 95 as illustrated in FIG. It can be effectively applied to the eyelashes.

On the other hand, the insertion hole 51 of the wiper 5 is slidably contacted so as to lightly tighten the outer periphery of the applicator rod 7 and the applicator 9 to wipe away the liquid cosmetic 100 and leave the excess liquid cosmetic 100 in the container body 1. At this time, the insertion hole 5 is slightly pushed up in the direction of the arrow B , compresses the funnel-shaped portion 55 in the axial length direction, closes the slit 53 strongly, and prevents the inflow of air into the container body 1 and the leakage of the liquid cosmetic 100. To prevent. To prevent the inflow of air into the container body 1, even when the liquid cosmetic 100 is stirred by the application rod 7 and the applicator 9 and bubbles 110 are generated , the volume of the liquid cosmetic 1 and the volume of air are substantially constant. keep. Therefore, no matter how much stirring is performed , the liquid cosmetic 100 containing the bubbles 110 in the container body 1 does not exceed the volume of the container body 1, and there is no problem of being ejected or leaking onto the wiper 5.

  Therefore, the combination of the applicator 9 that can accommodate the brush hair 95 in the concave groove 93 and the wiper 5 that prevents the pressure increase in the container body 1 by the slit 53 adheres the liquid cosmetic 100 to the tip of the brush hair 95. Can be taken out in a state. Moreover, even if the liquid cosmetic 100 is agitated, it is possible to realize an easy-to-use liquid cosmetic container that does not erupt or leak.

  As described above, the applicator according to the present invention has been described as an integrally formed applicator as shown in the figure, but the applicator 9 according to the present invention has brush hairs 95 substantially suspended from the bottom 92 side of the groove 93. It is good. That is, not only the brush bristles 95 are insert-molded into the applicator base 91 but also the bristles 95 alone are molded separately and fixed to the bottom 92 of the concave groove 93 by fusion, adhesion, or fitting. . In addition, a cylindrical brush hair obtained by twisting a fibrous brush bristle material between two wires is shaped into a semicircular arc and positioned at the bottom 92 of the concave groove 93. Further, it is also possible to integrally form the applicator bar 7, the applicator base 91, the bristles 95, and the comb portion 97.

As described above, the applicator 9 that suspends the bristle 95 from the bottom 92 of the concave groove 93 formed in the applicator base 91 and the wiper 5 provided with the slit 53 penetrating the front and back in the funnel-shaped portion 55 are combined. Thus, the effects described in the column of the effect of the invention are exhibited.
