Abstract

<P>PROBLEM TO BE SOLVED: To prevent a liquid cosmetic from spouting out due to the rise of pressure in a cosmetic container body having a wiping member for wiping the liquid cosmetic such as mascara when an application rod is inserted into the container body, and to prevent the uneven distribution of the liquid cosmetic remaining in an application part. <P>SOLUTION: A longitudinal rib 33 is arranged in the application rod 31 and a stroke piece 75 constituting a wiping part and formed in a substantially downward conical shape is made to abut on a stopper 81 for restricting the upper deformation of the stroke piece. Consequently, wiping in the application rod from the outer circumference of the application part to the end of the application part is reliably performed and also the uneven distribution of the liquid cosmetic remaining in the application part is eliminated. The longitudinal rib formed in the outer circumference of the application rod forms a gap between the application rod and the stroke piece to relieve the pressure in the container body for storing the liquid cosmetic. Thus, the liquid cosmetic is prevented from spouting out from the container body together with compressed air when the application rod is inserted and extracted. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a liquid cosmetic container for storing liquid cosmetics such as mascara, eyeliner, and lip gloss. More specifically, the present invention relates to an application bar and a wiping member, and more particularly to a liquid cosmetic container that creates a gap between the application bar and the wiping member to suppress an increase in pressure in the container body. The present invention also relates to a liquid cosmetic container that can squeeze liquid cosmetics adhering to the application part from the application bar to the tip of the application part.

  Liquid cosmetic containers used for mascara, eyeliner, lip gloss, etc. are used to apply the liquid cosmetic contained in the container body to the eyelashes, eyelids, lips, etc. by attaching it to the application part of the tip of the application bar. I am using it. The application part is provided with brush hairs, flocking members, sponge members, etc., which are called with a core material, at the tip of the application rod, and efficiently applies the liquid cosmetic to the eyelashes, eyelashes, lips and the like.

  The application part is immersed in the liquid cosmetic in the container body and adheres a lot of liquid cosmetic. Therefore, the liquid cosmetic material adhering excessively to the application part is adjusted to an appropriate amount by the ironing piece provided on the container body. Moreover, the ironing piece was always in close contact with the application bar in order to remove the liquid cosmetic material adhering to the application bar.

  However, since the application rod and the application member are inserted into and removed from the container body sealed by the wiping member, the internal pressure in the container body increases or decreases. When the internal pressure in the container body rises excessively, the wiping member is deformed, forming a gap and ejecting air in the container body. At this time, there was a risk that the liquid cosmetic adhering to the vicinity of the wiping member was also ejected together and the surroundings were soiled.

  In order to solve such problems, Patent Document 1 discloses a liquid makeup that forms a gap on the surface of the coating rod that prevents the liquid cosmetic material in the container body from inadvertently leaking and the air in the container body through the outside air and suppresses the increase or decrease in internal pressure. Proposal of a food container.

  In addition, the wiping member is required to have a function of wiping away the liquid cosmetic material adhering to the application bar cleanly and wiping off the excess liquid cosmetic material adhering to the application part. For this reason, Patent Document 2 proposes a method in which the surface of the application bar is wiped cleanly so that wiping has a direction and an opening serving as a wiping hole in the outer shape of the application bar is provided at the center of the application part.

Japanese Utility Model Publication No. 58-138510 JP 2004-000710 A

  In Patent Document 1, an air vent portion formed of a protrusion or a recess is formed on the surface of a shaft serving as an applicator rod, and an applicator serving as an applicator portion can be inserted while venting air pressurized in the container body. The piston formed on the shaft slides together with the inner surface of the handling body, which is a squeezing piece provided at the opening of the container body, to prevent the liquid cosmetic material from leaking. In addition, the handling body adheres and moves excess liquid cosmetic material adhering to the applicator and scrapes it into the container body.

  In Patent Document 1, the protrusion formed on the surface of the shaft comes into contact with the inner surface of the handle body, thereby creating a gap between the inner surface of the handle body and the air vent, thereby allowing the air inside and outside the container to flow and the pressure to be the same. . However, the air vent part leaks not only air but also liquid cosmetics. Therefore, a piston is provided to prevent leakage of the liquid cosmetic in the closed state.

  Closing the air vent by the piston pressurizes the air in the container body as the piston slides downward. For this reason, the liquid cosmetic left in the opening of the container body may be ejected together with the pressurized air when the lid is opened.

  Further, even when a cut is formed in the ironing portion of the handling body, the cut is widened by inserting the piston into the inner surface of the handling body and expanding the diameter of the ironing portion. The widened cuts are inconvenient in that the inside and outside of the container communicate with each other above and below the piston, and the liquid cosmetic in the container body flows out carelessly.

  Japanese Patent Application Laid-Open No. H10-228688 gives direction to the operating force of the wiping member so that the wiper, which becomes a scraping piece when the application member is pulled out from the container main body, reliably contacts the surface of the application bar or application portion. However, in the example of Patent Document 2, a wiping hole through which the application rod is inserted is provided so as not to hinder sliding when the application part is pulled out from the container body. The diameter of the opening serving as the wiping hole is not reduced, and the inside of the wiping hole of the liquid cosmetic adhering to the application part is not squeezed. For this reason, the liquid cosmetic material moves to the tip side of the application part, and excessive liquid cosmetic material is unevenly distributed, which causes inconveniences such as smearing the periphery of the makeup site and causing makeup failure.

  The present invention has been made in view of such problems, and the object of the present invention is to squeeze the liquid cosmetic adhering to the application part to the tip of the application part, so that excessive liquid cosmetic is unevenly distributed in the application part. It is intended to provide a liquid cosmetic container free from the above. It is another object of the present invention to provide a liquid cosmetic container in which the liquid cosmetic adhering to the application bar is wiped clean and the air pressure in the container main body is not increased, and the liquid cosmetic is not ejected in the container main body.

  In order to achieve the above object, the liquid cosmetic container of the present invention forms a gap through which the air in the container body is vented to the outside air without jetting the liquid cosmetic by contacting the longitudinal ribs of the application bar and the wiping member. In addition, a stopper that contacts the ironing piece and restricts deformation is provided, and the ironing piece is made to have a substantially conical shape downward, and a cut is made from the center side of the ironing piece so that it can be reliably wiped from the application bar to the tip of the application part. Is.

  That is, the coating rod has the coating rod having a vertical rib projecting linearly from the tip end side of the coating rod toward the middle position in the axial length direction, and the wiping member cut from the center side of the ironing piece, and the coating rod is a container The vertical rib pushes away the squeezing piece when inserting into and removing from the main body to form a gap in which air in the container body can be supplied and exhausted.

  In addition, the application rod having a vertical rib projecting linearly from the tip end side of the application rod toward the intermediate position in the axial length direction, a stopper portion inserted and fixed on the opening side of the container body, and below the stopper portion The wiping member is provided at an adjacent position and has a substantially conical shape facing downward with a wide opening on the stopper portion side, and forms a squeezing piece cut from the center of the tip. When pulling out from the container body, the wiping member is brought into contact with the stopper part, so that the application part presses the wiping member from the tip of the substantially conical shape downward, thereby pressing the iron piece in the axial direction and strengthening the application part. In addition to being able to squeeze out, the squeezing piece is prevented from being caught on the opening side, and the squeezing force of the coating part is stabilized.

  The liquid cosmetic container of the present invention has the following effects. That is, when the application part is inserted into the container body, the vertical ribs protruding from the outer periphery of the application bar come into contact with the ironing piece having elasticity and form a gap with the application body. Further, by making a plurality of cuts in the ironing pieces, the ironing pieces separated from each other by the cuts can be independently deformed. Therefore, the ironing piece makes a large difference in the amount of deformation due to contact with the vertical ribs, and a large gap can be formed in the cut portion. The gap can supply and exhaust the inside and outside of the container body to suppress an increase in pressure of the container body and prevent the liquid cosmetic from being ejected from the cosmetic outlet.

Further, by making the wiping member into a substantially conical shape downward, when the application bar and application part are pulled out, pressure is applied so that the squeezing piece is squeezed toward the center, and the remaining part from the application bar to the tip of the application part can be squeezed. Therefore, it is possible to eliminate the residual liquid cosmetic at the tip of the application part.
Further, since the squeezing piece constituting the wiping member is a downwardly substantially conical soft elastic body, when the application portion and the application rod are inserted from above the wiping member, they can be easily expanded and easily inserted. The ease of spreading of the wiping member is accompanied by a reduction in the squeezing force, reducing the amount of liquid cosmetic that is scraped off on the upper surface side of the substantially conical shaped squeezing piece, and reattaching when the application stick is pulled out from the wiping member. Can reduce unnecessary liquid cosmetics.

  Further, when the application part is pulled out from the container body, the wiping member is brought into contact with the stopper part to prevent the ironing piece from being caught on the opening side and to stabilize the ironing force of the application part.

  Next, the present invention will be described with reference to the drawings. FIG. 1 is an assembly cross-sectional explanatory view of a mascara container which is an example of the liquid cosmetic container of the present invention. The liquid cosmetic container according to the present invention includes a cylindrical container main body 13 that opens at the top and accommodates the liquid cosmetic 15, and a cap 11 that is screwed onto the container main body 13 and closed.

  FIG. 3C is an explanatory view of assembly of the third wiping member and the stopper portion. In FIG. 3C, the male screw portion 54 is formed integrally with the container main body 13, and therefore, the male screw portion 54 is different from the male screw 53 shown in FIGS. Part. The stopper portion 81 is formed to protrude from the inner surface of the fitting portion 58 that forms a cylindrical shape, and is fitted to the inner surface of the male screw portion 54 together with the fitting portion 58. Further, the wiping member 71 is disposed on the inner surface of the fitting portion 58 below the stopper portion 81 as in FIGS. 3C, the wiping member 71 is inserted on the inner surface of the fitting portion 58, but the wiping member 71 may be inserted on the outer periphery of the fitting portion 58.

  FIG. 4 is an explanatory view of the application stick insertion process in the liquid cosmetic container of the present invention and shows the process of ironing the liquid cosmetic. In FIG. 4, the neck tube 51 shown in FIG. 3 (A) is attached to the container body 13, and the description will be added. However, the second and third wiping members and stoppers shown in FIGS. 3 (B) and 3 (C). It is also possible to use parts that are assembled or modified. In the figure, the application part 91 is formed by a twist brush and is planted on the tip part 37 of the application bar 31. The application part 91 may be a hair-applied application part, an integrally formed application part, a sponge tip, or the like. .

  FIG. 4A shows an initial process of inserting the application rod 31 provided with the application portion 91 at the tip into the container body 13. In the figure, the application bar 31 is moved in the direction of arrow A to be inserted into the container body 13, but the vertical ribs 33 and the application part 91 projecting linearly on the outer periphery of the application bar 31 are located above the ironing piece 75. Yes. As shown in FIGS. 3A, 3 </ b> B, and 3 </ b> C, the wiping member 71 has an iron piece 75 that is substantially conical downward and forms the vicinity of the apex, and a plurality of incisions radially from the center side of the ironing piece 75. Is inserted, and the application rod 31 and the application part 91 can be inserted. Hereinafter, the description will be made on the assumption that no opening hole is provided, but it is also within the scope of the present invention to form an opening that can be inserted in close contact with the outer periphery of the coating rod 31.

  FIG. 4B shows a state where the application rod 31 is inserted in the direction of arrow A, and a part of the application part 91 provided at the tip part 37 has pushed the wiping member 71 away. In the drawing, the application section 91 pushes and spreads a downwardly substantially conical ironing piece 75 from above. Since the wiping member 71 is formed of a soft elastic body such as silicon rubber or urethane rubber that is easily stretched, the vicinity of the apex of the approximately conical squeezing piece 75 facing downward with a small pushing force is shown in FIG. Large opening with elongation. At this time, the squeezing force against the liquid cosmetic 15 adhering to the application part 91 is also reduced. Therefore, the amount of ironing remaining on the upper surface of the ironing piece 75 which is the surface opposite to the liquid cosmetic 15 in the container body 13 can be reduced. Further, it is possible to prevent the cosmetic 15 remaining when the application bar 31 is pulled out again from adhering to the application bar 31.

  FIG. 4C shows a state in which the application bar 31 is further inserted in the direction of arrow A, and the ironing piece 75 is in contact with the vertical rib 33 protruding linearly on the outer periphery of the application bar 31. Since the ironing piece 75 is in contact with both the vertical rib 33 and the outer periphery of the coating rod 31 at the position shown in FIG. 4C, a clearance is formed at the intermediate position between the two contact portions. Therefore, even when the application unit 91 is inserted until it is immersed in the liquid cosmetic 15, the air in the container body 13 can be vented in the direction of the arrow C to suppress abnormal pressure increase in the container body 13. Therefore, the liquid cosmetic 15 is prevented from being ejected from the cosmetic outlet 59.

  FIG. 5 is an arrangement explanatory view of the application rod and the wiping member in a state where the container body is closed with a cap as shown in FIG. 1, and shows a state where the application part 91 is immersed in the liquid cosmetic 15. In FIG. 5, the ironing piece 75 is in contact with the surface of the application bar 31 that is detached from the vertical rib 33.

  FIG. 6 is an explanatory diagram of the process of pulling out the application stick in the liquid cosmetic container of the present invention and shows the process of squeezing the liquid cosmetic. In FIG. 6 (A), the cosmetic 15 is pulled up together with the application part 91 from the container main body 13, and is further squeezed by the ironing piece 75. Since the ironing piece 75 is inserted through the application bar 31, the tip of the ironing piece 75 is deformed while being compressed in the axial direction by being pressed upward by the frictional force between the surface of the application bar 31 and the ironing piece 75.

  FIG. 6B shows a state in which the application bar 31 is further pulled out in the direction of the arrow B, and the iron piece 75 squeezes the application part 91 and wipes off the liquid cosmetic 15 adhering thereto. The ironing piece 75 is pulled out in the direction of the arrow B, slides on the surface of the application bar 31 to the tip part 37 of the application bar 31, and further moves to the center of the application part 91. The outer diameter of the brush bristles 95 forming the application part 91 is larger than the outer diameter of the application bar 31, and when the squeezing piece 75 moves to the application part 91, a large frictional force accompanying the deformation of the brush bristles 95 is generated. Therefore, the ironing piece 75 is pressed upward with a larger force than in the case of FIG. 6A and deforms so as to shrink more in the axial direction, but the deformation is restricted by contacting the stopper 81 to prevent the ironing piece 75 from being caught. The contact between the squeezing piece 75 and the stopper 81 can increase the squeezing force with respect to the application part 91. Eliminating the squeezing piece 75 can wipe the liquid cosmetic 15 in an appropriate amount and stably. The wiped liquid cosmetic 15 is returned to the original through the inner wall of the container body 13. FIG. 6C shows a state in which the application bar 31 is further pulled out in the direction of arrow B, and the iron piece 75 is wiped away from the liquid cosmetic 15 adhering to the tip of the application part 91.

  As described above, the example in which the wiping member is fitted in the container main body while being fixed to the neck tube has been described, but the present invention is not limited to the drawing, and the known invention is not limited thereto. It goes without saying that any configuration that produces an effect can be employed. Further, as shown in FIG. 3 (C), the male screw part is formed on the container body side, as well as the application part 91, the application part implanted in addition to the brush hair 95, the application part formed integrally, the sponge. A chip or the like may be used, and the use of such a known member does not depart from the scope of the present invention.
