Abstract
Description
[Technical Field]
[0001] The present invention relates to a container with an applicator, and more particularly to a container with an applicator for applying liquid cosmetics such as mascara, eyeliner, eyeshadow, and lip gloss. [Background technology]
[0002] Conventionally, a known container with an applicator for applying a liquid cosmetic such as mascara comprises a container body that contains the liquid content, a strainer that fits into the opening of the container body, a cap that is detachably attached to the opening of the container body, and a rod-shaped applicator that is attached to the cap and inserted into the strainer (see, for example, Patent Document 1).
[0003] The container with applicator described in Patent Document 1 has a strainer fitted into the opening of the container body, so that when the applicator is removed from the opening of the container body, excess content liquid adhering to the applicator can be strained off by the strainer. Also, the strainer of the container with applicator described in Patent Document 1 has an engaging portion formed on its outer circumferential surface that protrudes radially outward, so that when the applicator is removed from the container body, the strainer can be prevented from slipping out of the container body together with the applicator or from floating up from the opening of the container body. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-220972 Summary of the Invention [Problem to be solved by the invention]
[0005] However, in the container with applicator of Patent Document 1, if the content liquid dries and solidifies, causing the strainer and the applicator to stick together, a large pulling force acts on the strainer when the applicator is removed from the container body, which may make it impossible to prevent the strainer from coming off or floating up.To address this issue, it is thought that increasing the outer diameter of the locking part and increasing the overlap between the locking part of the strainer and the container body could prevent the strainer from coming off even when a large pulling force is applied, but there are restrictions on increasing the overlap because it would cause problems when attaching the strainer to the opening of the container body.
[0006] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a container with an applicator that does not cause any problems when attaching the strainer to the opening of the container body, and that can prevent the strainer from coming out when a large pulling force is applied to the strainer. [Means for solving the problem]
[0007] The characteristic configuration of the applicator-equipped container according to the present invention for solving the above problems is as follows: A container with an applicator, comprising: a container body in which an opening and a storage section are integrally formed; a strainer attached to the opening; a cap; and an applicator attached to the cap, The opening has an inner diameter smaller than the inner diameter of the housing portion, The sieving member has a cylindrical portion that fits into the opening and a hollow double-frusto-conical portion that is elastically deformable, The double truncated cone-shaped portion is configured to be disposed on the housing portion side when the cylindrical portion of the threshing member is attached to the opening.
[0008] According to the applicator-equipped container of this configuration, the scraper has an elastically deformable hollow double-frustoconical portion, so by stretching the double-frustoconical portion, the scraper can be easily inserted into the opening of the container body without any problems when attached to the opening. Furthermore, when the cylindrical portion of the scraper is attached to the opening, the double-frustoconical portion is configured to be positioned on the housing portion side. Therefore, even if a pulling force acts on the scraper, the double-frustoconical portion abuts the lower edge of the opening from below, preventing the scraper from slipping out. Furthermore, even if a large pulling force acts on the scraper when the applicator is removed from the container body, the double-frustoconical portion elastically deforms and contracts, increasing the engagement between the double-frustoconical portion of the scraper and the housing portion of the container body, preventing the scraper from slipping out or floating up.
[0009] In the container with an applicator according to the present invention, The maximum diameter of the double truncated cone-shaped portion is preferably larger than the inner diameter of the opening.
[0010] With this configuration of container with applicator, the maximum diameter of the double-truncated conical portion is larger than the inner diameter of the opening, which increases the engagement between the double-truncated conical portion of the strainer and the storage portion of the container body, preventing the strainer from coming loose when a large pulling force is applied to the strainer.
[0011] In the container with an applicator according to the present invention, The double truncated cone-shaped portion preferably has an inner peripheral surface formed with a setting jig projection against which a setting jig abuts.
[0012] In the container with applicator of this configuration, the double-truncated conical portion has a protrusion for a setting jig formed on its inner surface, with which the setting jig abuts. Therefore, when attaching the strainer to the opening, the double-truncated conical portion can be easily inserted into the opening and set by using the setting jig to extend the double-truncated conical portion.
[0013] In the container with an applicator according to the present invention, It is preferable that the double truncated cone-shaped portion has a maximum diameter that is thinner than the cylindrical portion.
[0014] According to the applicator-equipped container of this configuration, the portion of the double-frusto-conical portion with the maximum diameter is formed thinner than the thickness of the cylindrical portion, which facilitates elastic deformation of the double-frusto-conical portion. Furthermore, when the applicator is inserted, the internal pressure of the container body increases, and when the applicator is removed, a pump-up phenomenon occurs in which air inside the container body is ejected and liquid splashes at the same time. However, because the portion of the double-frusto-conical portion with the maximum diameter is formed thinner than the thickness of the cylindrical portion, the double-frusto-conical portion contracts as the internal pressure increases, thereby suppressing the increase in internal pressure and alleviating the pump-up phenomenon.

[0016] The present invention will be described below with reference to the drawings. However, the present invention is not intended to be limited to the embodiments described below or the configurations shown in the drawings. In the drawings, the shape, size, thickness, etc. of each part are appropriately exaggerated or simplified for ease of explanation, and the size and thickness of each part shown in the drawings do not strictly reflect the actual size relationship (scale).
[0017] <Overall structure> FIG. 1 is a cross-sectional view of a main portion of an applicator-equipped container 100 according to one embodiment of the present invention. The applicator-equipped container 100 shown in FIG. 1 contains a liquid content to be applied using an applicator 4. Examples of the liquid content include liquid cosmetics such as mascara, eyeliner, eye shadow, and lip gloss, as well as adhesives. As shown in FIG. 1, the applicator-equipped container 100 comprises a container body 1, a filter member 2, a cap 3, and an applicator 4. Each component of the applicator-equipped container 100 will be described in detail below.
[0018] <Container body> The container body 1 has an opening 11 and a storage section 12 formed integrally. The inner diameter of the opening 11 is smaller than the inner diameter of the storage section 12. In this embodiment, the storage section 12 is a cylindrical section with a bottom that stores the liquid content, and has the opening 11, which has a reduced diameter, connected to it above its shoulder. A male thread 13 is formed on the outer circumferential surface of the opening 11.
[0019] <Striking parts> As shown in Figure 1, the scraper 2 is attached to the opening 11. When the applicator 4 is removed from the container body 1, the lower end of the scraper 2 is pressed against the outer peripheral surface of the applicator 4, thereby scraping off excess liquid content adhering to the outer peripheral surface of the applicator 4. The scraper 2 is preferably made of an elastic material such as rubber, a thermoplastic resin elastomer, or a thermosetting resin elastomer.
[0020] As shown in FIG. 1, the threshing member 2 has a cylindrical portion 21 that fits into the opening 11 and a hollow, elastically deformable, double-frusto-conical portion 22. Here, the double-frusto-conical shape refers to a shape in which the bases of two truncated cones (circular truncated cones) are joined together. As shown in FIG. 1, the cylindrical portion 21 is cylindrical, and a flange 23 is formed at the upper end, protruding radially outward and extending continuously along the entire circumferential length. The flange 23 abuts against the upper edge of the opening 11, thereby positioning the threshing member 2 relative to the opening 11 and preventing the threshing member 2 from entering the cylindrical portion 21.
[0021] 1, when the cylindrical portion 21 of the threshing member 2 is attached to the opening 11, the double truncated cone-shaped portion 22 is configured to be positioned on the housing portion 12 side. With this configuration, even if a pulling force is applied to the threshing member 2, the double truncated cone-shaped portion 22 abuts against the lower opening edge of the opening 11 from below, preventing the threshing member 2 from slipping out or floating up.
[0022] 2A to 2C are cross-sectional views of the sieving member 2 of this embodiment, with (a) in an extended state, (b) in a normal (unloaded) state, and (c) in a contracted state. As shown in FIGS. 2A to 2C, the double-frusto-conical portion 22 has a hollow double-frusto-conical shape and is connected to the lower end of the tubular portion 21. Since the double-frusto-conical portion 22 is elastically deformable, as shown in FIG. 2A, by extending the double-frusto-conical portion 22, the maximum diameter D1 of the double-frusto-conical portion 22 becomes smaller than the inner diameter D0 of the opening 11 of the container body 1 shown in FIG. 1. Therefore, the sieving member 2 can be easily inserted into the opening 11 of the container body 1 without any problems.
[0023] In addition, as shown in Fig. 2(c), the double truncated cone portion 22 of the strainer 2 of this embodiment elastically deforms and contracts. Here, the maximum diameter D3 of the double truncated cone portion 22 in the contracted state shown in Fig. 2(c) is larger than the maximum diameter D2 of the double truncated cone portion 22 in the normal state shown in Fig. 2(b). Therefore, for example, if the content liquid dries and solidifies and the strainer 2 and the applicator 4 become stuck together, a large pulling force acts on the strainer 2 when the applicator 4 is removed from the container body 1. However, when the applicator 4 is pulled up in the stuck state, the double truncated cone portion 22 is also pulled up and contracted. Therefore, even if a large pulling force acts on the scraping member 2 when the applicator 4 is removed from the container body 1, the double truncated cone-shaped portion 22 elastically deforms and contracts, increasing the engagement between the double truncated cone-shaped portion 22 of the scraping member 2 and the storage portion 12 of the container body 1, thereby preventing the scraping member 2 from slipping out or floating up.
[0024] 1, the maximum diameter D2 of the double truncated cone-shaped portion 22 is preferably configured to be larger than the inner diameter D0 of the opening 11. This configuration increases the engagement between the double truncated cone-shaped portion 22 of the filtering member 2 and the storage portion 12 of the container body 1, preventing the filtering member 2 from coming off when a large pulling force is applied to the filtering member 2.
[0025] 3 is a cross-sectional view of a main portion of the applicator-equipped container 100 of this embodiment, showing how the filtering member 2 is set in the container body 1 using a setting jig S. The double-frusto-conical portion 22 preferably has a setting jig protrusion 24 formed on its inner circumferential surface against which the setting jig S abuts. As shown in FIG. 3, when the filtering member 2 is attached to the opening 11, the double-frusto-conical portion 22 can be easily inserted into and set in the opening 11 by extending the double-frusto-conical portion 22 using the setting jig S.
[0026] <Cap> The cap 3 is formed so as to be detachable from the opening 11. In this embodiment, the cap 3 is cylindrical, and an internal thread 31 that can be threaded onto the external thread 13 of the opening 11 is formed on the inner peripheral surface of the cap 3.
[0027] <Applicator> The applicator 4 includes a rod-shaped portion 41 and an applicator portion (not shown), and one end of the rod-shaped portion 41 is fixed to the cap 3. The applicator portion is fixed to the other end of the rod-shaped portion 41, and the applicator portion is housed inside the container body 1 with the cap 3 attached to the opening 11. The applicator portion is not particularly limited as long as it can contain the content liquid, and examples of the applicator portion include a brush-like, paintbrush-like, and sponge-like shape.
[0028] [Another embodiment] 4 is a cross-sectional view of a main part of an applicator-equipped container 200 according to another embodiment of the present invention. In this embodiment, parts that are the same as or similar to those in the above embodiment will be denoted by the same reference numerals in the drawings, and detailed description thereof will be omitted. The following description will focus on parts unique to this embodiment.
[0029] As shown in Fig. 4, the scraping member 2 in the applicator-equipped container 200 has a double truncated cone-shaped portion 25 that has a different shape from the embodiment shown in Figs. 1 to 3. In the embodiment shown in Figs. 1 to 3, the cylindrical portion 21 and the double truncated cone-shaped portion 22 are formed to have the same thickness, but in this embodiment, as shown in Fig. 4, the double truncated cone-shaped portion 25 has a thin-walled portion 25a that is formed by making the portion having the maximum diameter thinner than the cylindrical portion 21. By providing the thin-walled portion 25a that is formed by making the portion having the maximum diameter thinner than the cylindrical portion 21, the double truncated cone-shaped portion 25 can easily be elastically deformed. Furthermore, when the applicator 4 is inserted, the internal pressure of the container body 1 rises, and when the applicator 4 is removed, a pump-up phenomenon occurs in which the air inside the container body 1 is ejected and the liquid splashes out at the same time. However, by providing a thin-walled portion 25a where the part with the greatest diameter of the double truncated cone-shaped portion 25 is thinner than the thickness of the tubular portion 21, the double truncated cone-shaped portion 25 contracts as the internal pressure rises, thereby suppressing the rise in internal pressure and, as a result, reducing the pump-up phenomenon.
[0030] The above has been explained based on the embodiments of the container with applicator of the present invention, but the present invention is not limited to the configurations described in the above embodiments, and the configurations can be changed as appropriate within the scope of the spirit of the present invention, such as by appropriately combining the configurations described in each embodiment. [Industrial Applicability]
[0031] The container with applicator of the present invention does not cause any problems when the strainer is attached to the opening of the container body, and can prevent the strainer from coming out when a large pulling force is applied to the strainer, making it suitable for use as a container with applicator that is equipped with an applicator for applying liquid cosmetics such as mascara, eyeliner, eye shadow, and lip gloss.
