Summary of the Invention
Problems to be Solved by the Invention
[0004] However, in a conventional container with an applicator, since a large amount of the content liquid is likely to be retained in the brush, when the cap body is removed from the container body together with the applicator, the content liquid retained in the brush of the applicator cannot be sufficiently squeezed out by the squeezing cylinder member. Therefore, for example, it is necessary to press the brush against the mouth of the container body or a tissue to remove excess content liquid from the brush. In this case, there is a concern about waste of the content liquid and deterioration of operability. In addition, if there is excess content liquid retained in the brush, the content liquid cannot be evenly applied to the application portion.
[0005] The present invention provides a container with an applicator that allows the contents held in the applicator to be thoroughly scraped off by a scraping cylinder member when the cap is removed from the container body together with the applicator, while still being able to hold a sufficient amount of contents in the applicator. [Means for solving the problem]
[0006] A container with an applicator according to one aspect of the present invention comprises a container body disposed coaxially with a container axis extending in the vertical direction and containing a liquid, a cap body detachably attached to the mouth of the container body, a scraping cylinder member fitted inside the mouth of the container body, and a rod-shaped applicator attached to the cap body and inserted into the scraping cylinder member, wherein at least the outer circumferential surface of the lower end of the applicator has at least one of a plurality of circumferential grooves provided along the vertical direction and a plurality of circumferential grooves extending spirally around the container axis, and a liquid reservoir recess provided between adjacent circumferential grooves in the vertical direction and recessed radially inward.
[0007] Since a circumferential groove is formed on the outer surface of at least the lower end of the applicator, when the cap body is removed from the container body together with the applicator, the excess liquid adhering to the outer surface of the applicator can be scraped off with the scraping cylinder member, and only the liquid that has entered mostly into the circumferential groove can be retained by the applicator. This eliminates the need to remove excess liquid from the applicator using, for example, the mouth of the container body or a tissue. Since the outer surface of the applicator has a circumferential groove that holds the liquid contents, when the area to be applied is an eyelash, the liquid contents can be easily and evenly applied to the eyelash by inserting the eyelash into the circumferential groove. Since a liquid reservoir recess is formed on the outer circumferential surface of at least the lower end of the applicator, when the cap is removed from the container body together with the applicator, it is possible to retain the liquid contents not only in the circumferential groove but also in the liquid reservoir recess. By applying the liquid contents in the circumferential groove to the area to be coated while simultaneously moving the area to be coated into the liquid reservoir recess, the liquid contents of the liquid reservoir recess can be added to the circumferential groove as it is applied to the area to be coated. Therefore, when removing the cap body together with the applicator from the container body, it is possible to thoroughly scrape off the liquid contents held in the applicator with the scraping cylinder member, while still being able to hold a sufficient amount of liquid contents in the applicator.
[0008] The liquid reservoir recess may extend in the vertical direction and span two or more adjacent circumferential grooves in the vertical direction.
[0009] Since the liquid reservoir recess extends vertically and spans two or more adjacent circumferential grooves in the vertical direction, it becomes possible to easily move the part to be coated into the liquid reservoir recess while applying the liquid contents of the circumferential groove to the part to be coated, and the liquid contents of the liquid reservoir recess can be reliably added to and moved into the circumferential groove while being applied to the part to be coated.
[0010] The depths of the liquid reservoir recesses and the circumferential grooves are the same, and the liquid reservoir recesses may be arranged in a staggered pattern with spacing in the vertical direction and different positions in the circumferential direction.
[0011] The depths of the liquid reservoir recesses and the surrounding grooves are the same, and the liquid reservoir recesses are spaced apart vertically and positioned differently in the circumferential direction, creating a staggered pattern. This prevents a large amount of liquid from being applied to the surface to be coated when it enters a liquid reservoir recess, and also allows the surface to be coated to be dispersed into multiple liquid reservoir recesses, ensuring that the liquid is applied evenly and reliably to the surface to be coated.
[0012] The outer diameter of the lower end of the applicator may be 3.1 mm or less, the circumferential size of the liquid reservoir recess may be 0.5 mm or more and 1.0 mm or less, the pitch spacing of the circumferential grooves may be 0.4 mm or more and 0.7 mm or less, and the depth of the circumferential grooves may be 0.2 mm or more and 0.5 mm or less.
[0013] In this case, when the applicator is removed from the container body, a sufficient amount of the liquid contents can be reliably held on the outer surface of the applicator. [Effects of the Invention]
[0014] According to one aspect of the present invention, when the cap body is removed from the container body together with the applicator, the liquid contents held in the applicator can be sufficiently scraped off with the scraping cylinder member, while still allowing a sufficient amount of liquid contents to be held in the applicator.

[Figure 5] This is a side view of the lower part of the applicator in the container with the applicator according to the second embodiment. [Figure 6] This is a cross-sectional view taken along the line VI-VI in Figure 5. [Figure 7] This is a schematic diagram showing the lower end of the applicator when it has been removed from the container body in the second embodiment. [Modes for carrying out the invention]
[0016] The container with an applicator according to the first embodiment of the present invention will be described below with reference to Figures 1 to 4. As shown in FIG. 1, the container 1 with an applicator according to this embodiment includes a container body 11, a cap body 12, a squeegee cylinder member 13, and an applicator 14.
[0017] The container body 11 is formed in a bottomed cylindrical shape, the cap body 12 is formed in a capped cylindrical shape, the squeegee cylinder member 13 is formed in a cylindrical shape with both ends open, and the applicator 14 is formed in a rod shape. The container body 11, the cap body 12, the squeegee cylinder member 13, and the applicator 14 are arranged coaxially with a common axis (container axis) O.
[0018] Hereinafter, the side of the top wall 12a of the cap body 12 along the common axis O is referred to as the upper side, the side of the bottom 11a of the container body 11 along the common axis O is referred to as the lower side, and the direction along the common axis O is referred to as the vertical direction. Also, the direction intersecting the common axis O when viewed from the vertical direction is referred to as the radial direction, and the direction orbiting around the common axis O when viewed from the vertical direction is referred to as the circumferential direction.
[0019] The container body 11 houses a content liquid. Examples of the content liquid include mascara and adhesives. A male screw portion is formed on the outer peripheral surface of the mouth portion 11b of the container body 11. The cap body 12 is detachably attached to the mouth portion 11b of the container body 11. A female screw portion that is detachably screwed to the male screw portion of the mouth portion 11b is formed at the lower end portion of the inner peripheral surface of the cap body 12. The top wall 12a of the cap body 12 is located above the mouth portion 11b of the container body 11.
[0020] The squeegee cylinder member 13 is mounted within the mouth portion 11b of the container body 11. The squeegee cylinder member 13 is formed of an elastically deformable soft material such as nitrile rubber (NBR), low-density polyethylene (LDPE), and linear low-density polyethylene (LLDPE). The upper portion of the squeegee cylinder member 13 is fitted within the mouth portion 11b of the container body 11. The lower end portion of the squeegee cylinder member 13 is located below the mouth portion 11b.
[0021] A sealing portion 13a is formed at the upper end of the cutting cylinder member 13, projecting radially outward and extending continuously along its entire circumferential length. The sealing portion 13a is positioned at the upper opening edge of the mouth portion 11b. A stripping piece 13b is formed in the middle of the stripping cylinder member 13 in the vertical direction, projecting radially inward. The stripping piece 13b extends downward as it moves radially inward. The stripping piece 13b is formed in an annular shape and extends continuously along its entire circumferential length. The inner peripheral edge of the stripping piece 13b slides against the outer peripheral surface of the vertically moving applicator 14.
[0022] The applicator 14 is attached to the cap body 12 and inserted into the wiping cylinder member 13. The applicator 14 comprises a bottomed cylindrical fixing part 14a and a main shaft part 14b extending downward from the bottom wall of the fixing part 14a. The fixing portion 14a is fitted and fixed inside the cap body 12. The outer peripheral edge of the bottom wall of the fixing portion 14a is in liquid-tight contact with the upper surface of the sealing portion 13a of the scraping cylinder member 13. The lower part of the main shaft portion 14b is immersed in the liquid contents inside the container body 11. The outer circumferential surface of the main shaft portion 14b has a constricted portion 14d that is recessed radially inward and into which the scraping piece 13b is inserted. The lower end surface of the main shaft portion 14b is formed in a hemispherical shape that protrudes downward.
[0023] In this embodiment, a circumferential groove 15 and a liquid reservoir recess 16 are formed on the outer circumferential surface of at least the lower end of the applicator 14.
[0024] The circumferential groove 15 extends spirally over multiple turns around a common axis O. The groove width of the circumferential groove 15 narrows towards the inside in the radial direction. As shown in Figure 2, adjacent circumferential grooves 15 in the vertical direction are connected vertically via ridge portions 14c that protrude radially outward. However, adjacent circumferential grooves 15 in the vertical direction may be provided with a gap in the vertical direction without being connected by ridge portions 14c.
[0025] The liquid reservoir recess 16 is recessed radially inward and is located between adjacent circumferential grooves 15 in the vertical direction. In the illustrated example, the liquid reservoir recess 16 extends vertically and spans two or more adjacent circumferential grooves 15 in the vertical direction. The liquid reservoir recess 16 is located within the region of the applicator 14 where the circumferential grooves 15 are formed. The liquid reservoir recess 16 extends over more than half of the vertical portion of the region of the applicator 14 where the circumferential grooves 15 are provided. The vertical center of the region is located above the vertical center of the liquid reservoir recess 16. As shown in Figure 3, the depth of the liquid reservoir recess 16 is greater than the depth of the circumferential grooves 15. The internal volume of the circumferential grooves 15 is, for example, more than twice the internal volume of the liquid reservoir recess 16. The liquid reservoir recess 16 may extend radially through the applicator 14, and the depth of the liquid reservoir recess 16 may be the same as the depth of the circumferential groove 15.
[0026] For example, the outer diameter of the lower end of the applicator 14 is set to 3.1 mm or less, the circumferential size of the liquid reservoir recess 16 is set to 0.5 mm or more and 1.0 mm or less, the pitch spacing of the circumferential grooves 15 is set to 0.4 mm or more and 0.7 mm or less, and the depth of the circumferential grooves 15 is set to 0.2 mm or more and 0.5 mm or less. These values are set appropriately according to the properties of the liquid content.
[0027] As described above, with the container 1 with applicator according to this embodiment, a circumferential groove 15 is formed on the outer circumferential surface of at least the lower end of the applicator 14. Therefore, when removing the cap body 12 together with the applicator 14 from the container body 11, the excess liquid contents adhering to the outer circumferential surface of the applicator 14 can be scraped off with the scraping cylinder member 13, and as shown in Figure 4, only the liquid contents that have entered approximately into the circumferential groove 15 can be retained by the applicator 14. For example, this eliminates the need to remove excess liquid contents from the applicator 14 using the mouth 11b of the container body 11 or a tissue.
[0028] Since a circumferential groove 15 is formed on the outer surface of the applicator 14, which holds the liquid contents, when the area to be applied is an eyelash, the liquid contents can be easily and evenly applied to the eyelash by inserting the eyelash into the circumferential groove 15.
[0029] Since a liquid reservoir recess 16 is formed on the outer circumferential surface of at least the lower end of the applicator 14, when the cap body 12 is removed from the container body 11 together with the applicator 14, it becomes possible to hold the liquid contents not only in the circumferential groove 15 but also in the liquid reservoir recess 16. By applying the liquid contents in the circumferential groove 15 to the part to be coated while simultaneously moving the part to be coated into the liquid reservoir recess 16, the liquid contents of the liquid reservoir recess 16 can be added to the circumferential groove 15 while being applied to the part to be coated.
[0030] As described above, when removing the cap body 12 together with the applicator 14 from the container body 11, it is possible to sufficiently scrape off the liquid contents held in the applicator 14 with the scraping cylinder member 13, while still being able to retain a sufficient amount of liquid contents in the applicator 14.
[0031] Since the liquid reservoir recess 16 extends vertically and spans two or more adjacent circumferential grooves 15 in the vertical direction, it becomes possible to easily move the part to be coated into the liquid reservoir recess 16 while applying the liquid contents of the circumferential grooves 15 to the part to be coated, and the liquid contents of the liquid reservoir recess 16 can be reliably added to and moved into the circumferential grooves 15 while being applied to the part to be coated.
[0032] Since the outer diameter of the lower end of the applicator 14 is 3.1 mm or less, the circumferential size of the liquid reservoir recess 16 is 0.5 mm or more and 1.0 mm or less, the pitch spacing of the circumferential groove 15 is 0.4 mm or more and 0.7 mm or less, and the depth of the circumferential groove 15 is 0.2 mm or more and 0.5 mm or less, when the applicator 14 is removed from inside the container body 11, a sufficient amount of the contents can be reliably held on the outer surface of the applicator 14.
[0033] Next, a container 2 with an applicator according to the second embodiment of the present invention will be described with reference to Figures 5 to 7. In this second embodiment, the same reference numerals are used for parts that are the same as those in the first embodiment, and their descriptions are omitted. Only the differences will be described.
[0034] In the container 2 with applicator of this embodiment, the liquid reservoir recesses 26 are arranged in a staggered pattern, spaced apart in the vertical direction and with different positions in the circumferential direction. Multiple recess rows 17, each consisting of multiple liquid reservoir recesses 26 arranged in this staggered pattern, are provided at intervals in the circumferential direction. As shown in Figure 6, two recess rows 17 are provided, one on each side of the common axis O in the radial direction. Of the two recess rows 17, the vertical positions of the multiple liquid reservoir recesses 26 constituting one recess row 17 and the multiple liquid reservoir recesses 26 constituting the other recess row 17 are the same.
[0035] The depths of the liquid reservoir recess 26 and the circumferential groove 15 are the same. The liquid reservoir recess 26 connects two adjacent circumferential grooves 15 in the vertical direction. In a cross-sectional view perpendicular to the vertical direction as shown in Figure 6, the opening edge of the liquid reservoir recess 26 on the outer surface of the applicator 14 is formed in a curved shape (R-shape) that protrudes inward from the liquid reservoir recess 26. The depth of the liquid reservoir recess 26 may be greater than the depth of the circumferential groove 15.
[0036] As described above, in the container 2 with applicator according to this embodiment, the depths of the liquid reservoir recesses 26 and the circumferential grooves 15 are the same, and the liquid reservoir recesses 26 are spaced apart in the vertical direction and arranged in a staggered pattern with different positions in the circumferential direction. This prevents a large amount of liquid from being applied to the part to be coated that enters the liquid reservoir recesses 26, and also allows the part to be coated to enter multiple liquid reservoir recesses 26 in a dispersed manner, ensuring that the liquid is applied reliably and evenly to the part to be coated.
[0037] Furthermore, the technical scope of the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention.
[0038] For example, multiple circumferential grooves 15 may be provided along the vertical direction. In this case, the multiple circumferential grooves 15 may be provided at intervals in the vertical direction, or they may be provided in a series in the vertical direction. The outer surface of the applicator 14 may be provided with both a plurality of circumferential grooves arranged vertically and a circumferential groove 15 extending spirally over multiple turns around a common axis O, with their positions in the vertical direction differing. The outer circumferential surface of the applicator 14 may be provided with both a liquid reservoir recess 16 extending in the vertical direction and a row of recesses 17 consisting of multiple liquid reservoir recesses 26 arranged in a staggered pattern with spacing in the vertical direction and different positions in the circumferential direction, with both of these recesses positioned differently in the circumferential direction.
[0039] Furthermore, without departing from the spirit of the present invention, the components in the above embodiments may be replaced with well-known components as appropriate, and the above embodiments and modifications may be combined as appropriate. [Explanation of Symbols]
