Description

  The present invention relates to a cosmetic container for applying a liquid cosmetic.

  2. Description of the Related Art Conventionally, in a cosmetic container having a container for storing liquid cosmetics such as mascara, an extra liquid cosmetic adhering to the applied body is applied to the opening neck (mouth) where the applied body is taken in and out. A cylindrical member for scraping (hereinafter referred to as a wiper) is often mounted. In such a cosmetic container, the wiper is pulled by the application body (particularly the shaft portion) when the application body is pulled up from the inside of the container and the excess liquid cosmetic adhering to the application body is scraped off by the scraping hole of the wiper. May come out of the open neck.

  In the following Patent Document 1, the wiper is extended below the scraping hole, and at the lower end of the extended portion, a thin portion extending upward or a slit extending upward and communicating between the inside and the outside is provided and applied. When the body is bent outward in the radial direction and the applied body is pulled up to scrape excess liquid cosmetic with the scraping holes, the bent portion of the applied body hits the extension of the wiper. The extension portion is deformed and expanded by the thin portion or the slit, and the wiper can be prevented from coming out.

  In Patent Document 2 below, a slit that extends upward and communicates between the inside and the outside is provided at the lower end of the wiper, and this slit facilitates elastic deformation of the wiper and facilitates mounting of the wiper on the opening neck. An annular collar is provided at the lower part of the wiper, and the collar is axially opposed to the inner surface of the shoulder of the housing (the stepped portion connected to the opening neck at the end of the housing). This prevents the opening neck from coming off, and prevents the wiper from slipping off when the excess liquid cosmetic adhering to the coated body is scraped off.

  Hereinafter, a preferred embodiment of a cosmetic container according to the present invention will be described with reference to FIGS. 1 is a longitudinal sectional view showing a cosmetic container according to an embodiment of the present invention, FIGS. 2 and 3 are longitudinal sectional views of the wiper in FIG. 1, and FIGS. 4 and 5 are FIG. It is each arrow figure, and the cosmetic container 100 of this embodiment is used when the user applies the liquid cosmetic L to the skin such as the face which is the application portion. Here, the liquid cosmetic L is a mascara as being particularly suitable, but other liquid cosmetics such as an eyeliner may of course be used, and various liquid cosmetics can be employed.

  As shown in FIG. 1, the cosmetic container 100 generally includes a container body 1 that stores the liquid cosmetic L, and a lid portion 2 that is a cap with an applicator that is detachably attached to the container body 1. doing.

  The container main body 1 includes a storage portion 3 for storing the liquid cosmetic L, and an open neck portion 4 integrally connected to the upper portion of the storage portion 3 and connected to the storage portion 3. The accommodating portion 3 is configured in a bottomed cylindrical shape and accommodates the liquid cosmetic L therein, and the opening neck portion 4 is configured in a cylindrical shape having a smaller diameter than the accommodating portion 3 and is disposed coaxially. Are connected via a stepped portion 12 (so-called shoulder portion) whose diameter is reduced, and the inside of the cylinder communicates with the housing portion 3.

  A male screw 5 for removably screwing the lid 2 is formed on the outer peripheral surface of the opening neck 4. In addition, a cylindrical wiper 6 (described in detail later) for scraping off excess liquid cosmetic L adhering to an applicator 11 described later on the lid 2 is attached to the opening neck 4 by press-fitting. .

  The lid portion 2 is formed in a bottomed cylindrical shape, and has an internal thread 7 that is screwed into the external thread 5 on the outer peripheral surface of the opening neck 4 on the inner peripheral surface on the opening end side. The lid 2 is detachably attached to the container body 1 by screwing the female screw 7 to the male screw 5.

  The lid 2 is provided with an applicator 11. The applicator 11 includes a shaft portion 9 that protrudes from the inside of the lid portion 2 toward the housing portion 3 side (downward in the drawing) of the container body 1, and an application body 10 provided at the tip of the shaft portion 9. .

  The shaft portion 9 forms a cylindrical body having a smaller diameter than the lid portion 2, passes through the cylindrical hole of the wiper 6, and can pass through a scraping hole 8 (details will be described later) of the wiper 6.

  Here, the application body 10 is a mascara brush. This mascara brush 10 has brush hairs 16 attached to a core body 17, and more specifically, the brush body 16 is sandwiched between two core wires constituting the core body 17 and tightened. The diameter is smaller than the diameter of the shaft portion 9. When a liquid cosmetic other than mascara is used, an applicator such as a brush, a brush, a brush, a chip, or a comb can be used as the application body.

  When the lid portion 2 is attached to the opening neck portion 4 of the container main body 1 by screwing the screws 5 and 7 (when the lid portion 2 is tightened), the shaft portion 9 passes through the scraping hole 8 of the wiper 6 and the container. It enters into the storage part 3 of the main body 1, and the application body 10 is configured to be immersed in the liquid cosmetic L stored in the storage part 3.

  Here, the wiper 6 is compression-molded rubber and is configured in a bottomed cylindrical shape. As shown in FIGS. 1 to 3, the wiper 6 has an annular flange 19 at its upper end.

  The lower end surface of the collar portion 19 abuts on the upper end surface of the opening neck portion 4, thereby preventing the wiper 6 from moving further downward. On the flange 19 (upper end surface of the wiper 6), when the lid 2 is mounted on the opening neck 4 of the container body 1, an airtight annular projection 15 that is in close contact with the inner surface 18 of the lid 2. Is provided.

  Further, the wiper 6 has an annular step portion (here, a flange portion) 13 on the outer peripheral surface on the lower side. The stepped portion 13 has a diameter larger than the inner peripheral surface of the opening neck portion 4 and is positioned in the accommodating portion 3 of the container main body 1 and engages with the inner surface 22 of the stepped portion 12 of the container main body 1 in the axial direction (face-to-face). Thus, it functions as a stopper that prevents the wiper 6 from moving further upward.

  A scraping hole 8 through which the applicator 11 (the shaft portion 9 and the applicator body 10) passes is provided in the approximate center of the bottom of the wiper 6. The inner diameter of the scraping hole 8 is slightly smaller than the outer diameter of the shaft portion 9 of the applicator 11. And the periphery which forms this scraping hole 8 scrapes off the excess liquid cosmetics adhering to the axial part 9 and the application body 10 of the applicator 11 which pass the said scraping hole 8. FIG.

  On the inner peripheral surface of the wiper 6, a plurality of thick portions 14 extending in the axial direction and projecting inward are arranged in parallel along the circumferential direction. The thick portion 14 extends a predetermined length from the bottom along the axial direction (here, extends to the vicinity of the upper end surface), and as shown in FIGS. The thick part 14b and the lower thick part 14c are continuously provided.

  The upper thick portion 14a is configured to be gently inclined so as to increase in thickness toward the lower side, and the radial thickness is relatively small. The subsequent intermediate thick portion 14b is steeper than the upper thick portion 14a. The thickness in the radial direction is large due to the inclination, and the subsequent lower thick portion 14c is the same thickness as the lower end of the intermediate thick portion 14b, and its inner surface 21 extends vertically (in the axial direction). It extends in parallel and reaches the bottom, and its lower end is located in the vicinity of the scraping hole 8. As shown in FIG. 3, the lower thick portion 14 c has a height H from the bottom surface of the wiper to the upper end thereof that is substantially the same as the height from the bottom surface of the wiper to the step surface 23 of the step portion 13. .

  In the present embodiment, the thick portion 14 composed of the upper thick portion 14a, the intermediate thick portion 14b, and the lower thick portion 14c is formed on the inner peripheral surface of the wiper 6 as shown in FIGS. Since they are arranged side by side along the circumferential direction, the thick wall portion 14 and the concave portion 20 are continuously arranged along the circumferential direction on the inner circumferential surface of the wiper 6 so that the unevenness is continuous. Yes.

  Therefore, when the wiper 6 is mounted on the opening neck 4 of the container body 1, the recesses 20 that are spaced apart from each other along the circumferential direction and extend in the axial direction are narrowed down. It can be easily attached to the opening neck 4.

  When using the cosmetic container 100 configured in this manner, from the state shown in FIG. 1, the user pulls up the lid 2 by turning the lid 2 and releasing the screwing of the screws 5 and 7. Is removed from the container body 1. At this time, the shaft portion 9 of the lid portion 2 passes through the scraping hole 8 of the wiper 6, and the peripheral edge forming the scraping hole 8 is raised, and the liquid makeup adhered around the shaft portion 9 by the peripheral edge. Fee L is scraped off.

  In this state, the wiper 6 is squeezed inward (contracted) over the entire circumferential direction by the shaft portion 9 of the applicator 11 and pulled upward to pull out from the opening neck portion 4. The thick portion 14 (particularly the lower thick portion 14c) that is spaced apart from the circumferential direction of the surface and protrudes inward is prevented from being squeezed inward, and this thick portion 14 (especially the lower thick portion 14c) is located on the inner circumferential surface on the radially inner side of the step portion 13 of the wiper 6, so that the disengagement between the step portions 12 and 13 is suppressed. As a result, the wiper 6 Is prevented from coming out of the opening neck 4. As described above, the thick portion 14 (particularly the lower thick portion 14 c) only needs to be positioned on the radially inner inner peripheral surface of the step portion 13 of the wiper 6.

  Then, the application body 10 passes through the scraping hole 8 following the lifting of the shaft portion 9, but the outer diameter of the core body 17 of the application body 10 is smaller than the outer diameter of the shaft portion 9. Necessary liquid cosmetic L remains attached to the surrounding brush hairs 16, and the liquid cosmetic L adhered to the brush hairs 16 is applied. When the application is finished, the lid 2 is removed in the opposite direction. The lid 2 is attached to the container main body 1 while turning the screws 5 and 7 together.

  As described above, in the present embodiment, the thick portion 14 that extends in the axial direction and protrudes toward the inside is provided on the inner peripheral surface of the wiper 6 so as to be spaced apart from each other along the circumferential direction. Concavities and convexities are continuously arranged along the circumferential direction on the peripheral surface, and the concave portion 20 of the concavities and convexities extending in the axial direction is narrowed when the wiper 6 is attached to the opening neck portion 4, and as a result, The wiper 6 can be easily attached to the opening neck 4. Further, the stepped portion 13 of the wiper 6 that engages in the axial direction with the stepped portion 12 of the container main body 1 serves as a stopper against the opening neck portion 4, and in addition, the applicator 11 is pulled up from the housing portion 3 and attached. When the excess liquid cosmetic L is scraped off by the scraping hole 8 of the wiper 6, the thick wall portion 14 (particularly, spaced apart from the inner peripheral surface of the wiper 6 along the circumferential direction and projecting inward) The lower thick portion 14 c) prevents the wiper 6 from being squeezed inward, and this thick portion 14 (particularly the lower thick portion 14 c) is the inner circumference in the radial direction of the stepped portion 13 of the wiper 6. Since it is located on the surface, the disengagement between the stepped portions 12 and 13 is suppressed, and as a result, the wiper 6 can be prevented from coming out of the opening neck portion 4.

  Moreover, in this embodiment, the thick part 14 is inclined so that it may become thick along with the upper side thick part 14a, the intermediate | middle thick part 14b, and the lower side thick part 14c toward the bottom part. Therefore, the inclined portion serves as a guide for the user to guide when the application body 10 at the tip of the applicator 11 enters the scraping hole 8, and the application body 10 easily enters the scraping hole 8. Can be made.

  Further, the wiper 6 has an airtight annular protrusion 15 on the end surface opposite to the bottom portion, which is in close contact with the inner surface 18 of the lid portion 2 when the lid portion 2 is attached to the opening neck portion 4. The annular projection 15 for airtightness and the inner surface 18 of the lid portion 2 are in close contact with each other, and volatilization of the liquid cosmetic L is prevented.

  The thick portion 14 is not formed below the scraping hole 8 in the axial direction.

  FIG. 6 is a longitudinal sectional view showing a cosmetic container according to another embodiment of the present invention.

  The cosmetic container 200 of this embodiment is different from the cosmetic container 100 of the previous embodiment, in particular, the engagement of the step 13 of the wiper 6 that engages the step 12 of the container body 1 in the axial direction. The thickness A in the radial direction of the surface is determined from the outer peripheral surface of the shaft portion 9 passing through the scraping hole 8 of the wiper 6 to the outer peripheral surface (specifically, on the inner side of the lower thick portion 14c). This is a point set longer than the length B up to the surface 21).

  In the present embodiment, the radial length A is the wiper 6 because the wiper 6 is press-fitted into the opening neck 4 of the container body 1 and the outer peripheral surface of the wiper 6 and the inner peripheral surface of the opening neck 4 are in close contact. This is the same as the length AA (see FIG. 3) in the radial direction of the step surface 23 of the six step portions 13. Incidentally, when the outer peripheral surface of the wiper 6 and the inner peripheral surface of the opening neck 4 are not in close contact with each other and there is a gap between the outer peripheral surface of the wiper 6 and the inner peripheral surface of the opening neck 4, the level difference of the container body 1 is obtained. The radial length A of the engagement surface of the step portion 13 of the wiper 6 that engages the portion 12 in the axial direction is shorter than the radial length AA of the step surface 23 of the step portion 13 of the wiper 6. Further, since the outer diameter of the shaft portion 9 is slightly larger than the inner diameter of the scraping hole 8, the length B is from the scraping hole 8 in a state where the shaft portion 9 does not pass through the scraping hole 8. It is slightly shorter than the length BB (see FIG. 2) to the inner surface 21 of the thick portion 14.

  According to the cosmetic container 200 configured in this manner, the lid 2 is removed from the container body 1, the shaft 9 passes through the scraping hole 8 of the wiper 6, and the wiper 6 is squeezed inward by the shaft 9 ( Engagement surface (in this case, a step surface) of the step portion 13 of the wiper 6 that engages in the axial direction with the step portion 12 of the container body 1 when pulling upward and pulling out from the opening neck portion 4 23) from the outer peripheral surface of the shaft portion 9 passing through the scraping hole 8 of the wiper 6 to the thick portion 14 (here, the lower thick portion 14c) facing the outer peripheral surface. Therefore, before the engagement between the stepped portions 12 and 13 in the axial direction is released, the shaft portion 9 passing through the scraping hole 8 has a thick portion 14 (here, the lower thickness). It comes into contact with the inner surface 21) of the meat portion 14c.

  Accordingly, the wiper 6 is not further squeezed inward, the engagement between the stepped portions 12 and 13 is suppressed, and the wiper 6 can be reliably prevented from coming off from the opening neck portion 4.

  The present invention has been specifically described above based on the embodiment. However, the present invention is not limited to the above embodiment. For example, in the above embodiment, the upper thick portion 6a has a gentle slope. However, this particularly takes into consideration the draft angle of the mold at the time of manufacture, and it may be a thick part parallel to the axial direction without being gently inclined.

  Moreover, in the said embodiment, although the scraping hole 8 is provided in the bottom part of the wiper 6, as mentioned above, the thick part 14 (especially lower side thick part 14c) pulls out the wiper 6. In order to prevent this, as shown in FIG. 7, it is necessary to be positioned on the inner circumferential surface on the radially inner side of the stepped portion 13 of the wiper 6 (must be positioned within the range of Y), and Therefore, the scraping hole 8 is formed on the inner peripheral surface (range Z) of the wiper 6 below the step portion 13 (range Y). As long as it is a position below the thick portion 14 in the axial direction, it may be provided at any position.

  Furthermore, in the embodiment described with reference to FIG. 6, it is particularly preferable that the radial length A of the engaging surface of the stepped portion 13 of the wiper 6 that is engaged with the stepped portion 12 of the container body 1 in the axial direction is set as the wiper. 6 is longer than the length B from the outer peripheral surface of the shaft portion 9 passing through the scraping hole 8 to the thick portion 14 (here, the lower thick portion 14c) facing the outer peripheral surface. Even if A ≦ B, as in the embodiment described in FIGS. 1 to 5, the thick portion 14 (particularly the lower thick portion 14 c) prevents the wiper 6 from being squeezed inward, and the thickness is increased. Since the meat portion 14 (particularly the lower thick portion 14c) is located on the radially inner peripheral surface of the step portion 13 of the wiper 6, the disengagement between the step portions 12 and 13 is suppressed, and as a result, The wiper 6 can be prevented from coming off from the opening neck 4.
