Description

  The present invention relates to an ironing member for scraping off excess contents adhering to an application body in a container with an application body and including an appropriate amount of content in the application body, and a container with an application body using the ironing member.

  Conventionally, containers with an application body that contain contents such as paste-like lip gloss, paste-like lipstick, mascara, and other cosmetics having a certain degree of viscosity, and that are applied to the application body when applied are known. It has been. Such an application body includes a shaft portion integrally provided on the lid portion and an application portion such as a brush continuously provided at the tip of the shaft portion, and the lid portion is removed from the mouth / neck portion of the container during use. Pulled out from.

  Since extra contents are attached to the application body before use, an inner stopper with a so-called “squeezing part” is provided in the mouth and neck of the container, and when the application body is pulled out from the container during use, It is common to scrape off the excess contents adhering to the application body and the shaft portion by the part, and to include an appropriate amount of contents in the application body. Further, the ironing portion has an effect of ensuring airtightness in the container at the time of closing.

  4 (a) is a partially cutaway sectional view of a conventional ironing part, FIG. 4 (b) is a bottom view thereof, and FIG. 5 is a sectional view of an example of a conventional container with an application body provided with the ironing part. . The inner plug main body provided with the ironing portion is hereinafter referred to as a “ironing member”. The ironing member 1 is formed in a substantially cylindrical shape, and the ironing part 11 is provided on the inner peripheral surface thereof. The ironing portion 11 is gradually narrowed in the direction of the container body, and is formed in a substantially conical surface having an opening 12 through which the application portion and the shaft portion of the application body can be inserted. And, in order to maximize the scraping effect when the application body 2 is pulled out from the container, and to reduce the resistance of insertion / removal of the application body 2, it is generally formed in a thin shape with a deformable material. Is.

  Since the squeezing member 1 is inserted into the mouth / neck portion 31 of the container 3 and attached, the container mouth / neck portion 31 prevents the container mouth / neck portion 31 from slipping out of the container or falling into the container. The flanges 13 and 14 are provided on the upper and lower portions of the container so as to protrude outwardly from the inner diameter of the mouth / neck portion 31 and engage with the upper and lower ends of the container neck portion 31. When the ironing member 1 is inserted into the mouth-and-neck portion 31 and attached, the ironing member 1 is elastically deformed and attached so that the flange 14 does not interfere with the insertion.

  Thus, the ironing member 1 is formed of a deformable elastic material for the scraping effect at the time of use, insertion / removal of the application body 2, and ease of mounting on the container 3 main body. Therefore, as the application body 2 is repeatedly inserted and removed, the ironing member 1 is twisted or greatly deformed, the flanges 13 and 14 are disengaged, and the ironing member 1 is pulled out of the container mouth / neck portion 31 to the outside of the container. I was depressed. In particular, when the cosmetic material adhering to the lid portion 4 or the shaft portion 21 of the application body 2 is dried, portions that are in close contact with the lid portion 4 or the shaft portion 21 and the ironing member 1 may be in an adhesive state. If the shaft portion 21 is forcibly inserted and removed in this state, an external force such as a twisting force is applied to the ironing member 1, and the ironing member 1 having elasticity may be greatly deformed and detached from the container neck portion 31.

  In order to prevent the ironing member from falling off, Patent Document 1 discloses a flange for engagement of the ironing member provided with a reinforcing projection. Further, Patent Document 2 discloses an annular lip corresponding to a flange for engaging the ironing member that protrudes at an acute angle with respect to the ironing member.

  However, these materials have an effect when the application body and the shaft portion are pulled out straight, but they cannot cope with dropout caused by deformation due to torsional force.

  Therefore, the present invention overcomes such drawbacks of the conventional ironing container-equipped container member, has rigidity against external force such as torsional force applied to the ironing member during use, and effectively prevents the container from falling off due to elastic deformation. An object of the present invention is to provide an ironing member and a container with an application body using the ironing member.

  The present invention solves the above-mentioned problem, is formed in a substantially cylindrical shape that can be mounted in a container mouth neck, and has an ironing portion having an opening through which an application body can be inserted on its inner peripheral surface. The upper and lower parts of the outer peripheral surface are ironing members with flanges that can be engaged with the upper and lower ends of the container neck. The lower side of the lower flange is compared with other flange parts. The ironing member is characterized in that a thick portion formed thick in the axial direction of the ironing portion is provided.

  Further, the present invention is a rubbing member comprising a rib formed on a protruding line so that at least a part thereof is hung on an inner peripheral surface in a range corresponding to a portion where the lower flange is provided. It is.

  Furthermore, this invention is a container with an application body provided with those ironing members.

  The ironing member according to the present invention has a lower flange that is most stressed when the applied body is pulled out of the container and has a high rigidity in the vicinity of the flange. As a result, the lower flange is disengaged and the ironing member can be effectively prevented from coming off the container.

  In addition, in the present invention, a rib provided with a reinforcing rib on the inner peripheral surface is coupled with a thick portion provided on the flange, so that the rigidity of the flange and the vicinity of the flange becomes higher. Even if added, elastic deformation does not easily occur. Therefore, it is possible to effectively prevent the flange member from being disengaged and the ironing member from coming out of the container.

  Hereinafter, embodiments of the ironing member of the present invention and the container with the application body using the ironing member will be specifically described with reference to the drawings. Note that the present invention is not limited to these embodiments.

  As shown in FIG. 1, the ironing member 1 of the present invention is formed in a substantially cylindrical shape, and an inner peripheral surface thereof is gradually narrowed toward the container body, and an opening 12 through which the application body 2 can be inserted is formed in the center. An ironing portion 11 is provided. In addition, a flange 13 is provided on the upper part of the outer peripheral surface of the ironing member 1 so as to protrude outwardly from the inner diameter of the container neck portion 31, and the container mouth neck portion 31 is provided on the lower portion of the outer peripheral surface. A flange 14 that protrudes outwardly from the inner diameter in a bowl shape is provided.

  The flange 14 in the present embodiment is such that its lower side surface 141 is downward from the outer peripheral side of the flange 14 toward the inner peripheral side so that it can be easily inserted into the container neck portion 31 when the ironing member 1 is attached to the container 3. It is formed to be inclined. Further, on the lower side surface 141, a thick portion 15 is formed integrally with the flange 14 so as to be thicker in the axial direction (vertical direction in the drawing) of the ironing member 1 than the other flange 14 portion. .

  The thick portion 15 is formed to have a constant width when viewed from the bottom, extends radially from the outer peripheral surface of the ironing member 1 toward the outer periphery of the flange 14, and a plurality of the thick portions 15 are provided intermittently in the circumferential direction of the flange 14. The protruding height h in the axial direction of the thick portion 15 is arbitrary, but is preferably 0.5 mm or more, and more preferably 1 to 3.5 mm. Moreover, in this embodiment, although the thick part 15 is provided in six places, the number is arbitrary and it is preferable to provide 3-8 places. Further, the width of the thick portion 15 is not constant as in this embodiment, and the width may be changed between the inner peripheral side and the outer peripheral side. Further, the thick portion 15 of the present embodiment has a substantially rectangular cross-sectional shape, but the cross-sectional shape is not limited to this, and a semicircular or elliptical shape from the lower side surface 141, a triangle or other polygons, etc. You may form so that it may protrude. Further, the lower side surface 141 on which the thick portion 15 is not formed is not formed in the conical inclined surface as in the present embodiment, but is formed in a curved shape recessed in a substantially U shape between the thick portions 15. It may be formed.

  Furthermore, the proportion of the thick portion 15 in the lower side surface 141 is arbitrary, but the ironing member 1 is inserted into the neck portion 31 and attached while maintaining the rigidity necessary for preventing the ironing member 1 from coming off. In order to obtain the necessary elastic deformation, the area ratio of the thick portion 15 to the lower surface 141 is preferably 40% or more, and more preferably in the range of 50 to 75%.

As the ironing member 1 of the present invention, one integrally molded with a thermoplastic resin can be used. Specifically, elastic materials such as elastomers such as NBR (nitrile rubber), thermoplastic polyurethane, thermoplastic elastomer, soft PE, soft PP, silicon rubber, EVA resin (ethylene / vinyl acetate copolymer resin), natural rubber, etc. Can be mentioned.

  FIG. 2 is a cross-sectional view of a container with an application body provided with the ironing member 1 of the present invention. As shown in the drawing, the ironing member 1 has a cylindrical main body portion, except for the upper and lower flanges 13 and 14, completely inserted into the mouth-and-neck portion 31 of the container 3. The upper flange 13 is engaged with the upper end portion of the mouth / neck portion 31, and the lower flange 14 is also engaged with the lower end portion of the mouth / neck portion 31, whereby the ironing member 1 is fixed to the container 3. .

  In the state of FIG. 2, the threaded portion of the inner peripheral surface of the lid portion 4 is screwed into the threaded portion of the outer peripheral surface of the mouth / neck portion 31 of the container 3, and is formed to project downward from the lid portion 4. The shaft portion 21 is inserted through the opening 12 of the ironing portion 11, and the application portion 22 provided at the tip of the shaft portion 21 is immersed in a cosmetic (not shown) in the container 3. .

  When the application body 2 is pulled out from the container 3 during use, stress in the pulling direction acts on the ironing member 1 through a contact portion between the ironing section 11 and the application body 2 or the like. In addition, when the contents adhering to the flange 13 exposed to the outside of the container 3 are dry, the portion where the flange 13 and the lid 4 are in close contact with each other is in an adhesive state. And when rotation is added to the application body 2 in order to remove the cover part 4 screwed to the container neck part 31, the ironing member 1 itself is caused by the adhesion state of the ironing member 1 and the cover part 4. A strong twisting force is applied.

  However, since the ironing member 1 of the present invention is provided with the thick portion 15 at a part of the flange 14, the flange 14 and the vicinity of the flange 14 that are most stressed when the applied body 2 is pulled out from the container 3 have high rigidity. Even when a strong twisting force as described above is applied, elastic deformation does not easily occur, and as a result, it is possible to effectively prevent the flange 14 from being disengaged.

  Further, FIGS. 3A to 3C show the ironing member 1 of the present invention provided with reinforcing ribs 17. The ribs 17 are formed on the inner peripheral surface of the ironing member 1 and have a protruding line that hangs on the inner peripheral surface 16 in a range corresponding to the portion where the flange 14 is provided.

  The ribs 17 are formed to have a constant width when viewed from the bottom, and in this embodiment, six ribs 17 are provided intermittently in the circumferential direction of the inner peripheral surface of the ironing member 1. The rib 17 is provided below the ironing portion 11 so as to extend from the lower end of the ironing member 1 to an arbitrary length in the axial direction, but in a range corresponding to the portion where the flange 14 is provided. If the rib 17 is hung on the inner peripheral surface 16, the length of the rib 17 is arbitrary, and it is not necessarily provided from the lower end of the ironing member 1.

  The protrusion height of the rib 17 in the center direction of the ironing member 1 is arbitrary, but is preferably 0.3 mm or more, and more preferably 0.5 to 2.5 mm. Moreover, in this embodiment, although the rib 17 is provided in six places, the number is arbitrary and it is more preferable to provide 3-8 places. Furthermore, although the width of the rib 17 is arbitrary, 0.8 mm or more is preferable and 1-2.5 mm is more preferable. In this embodiment, the rib 17 is formed so as to extend in the direction perpendicular to the flange 14 along the axial direction of the ironing member 1, but the extending direction is not limited to this, and for example, the ironing member It may be formed so as to extend obliquely with respect to one axial direction, or may be formed so as to extend along the circumferential direction of the inner peripheral surface so as to be parallel to the flange 14. In the latter case, the rib 17 may be a continuous annular rib on the inner peripheral surface.

  Although the cross-sectional shape of the rib 17 of this embodiment is formed in a substantially trapezoidal shape, the cross-sectional shape of the rib 17 is not limited to this, and is formed in a semicircular shape, a semi-elliptical shape, or a triangular or other polygonal shape.
