Description

[Technical field]

[0001] The present invention relates to an application container. [Background technology]

[0002] Conventionally, as shown in Patent Document 1 below, for example, there has been known an application container comprising a container body in which the contents are contained, an inner plug member fixed to the mouth of the container body and having a communication hole that communicates with the inside of the container body, and a support member fixed to the inner plug member and having a support recess that rotatably supports an application ball. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2012-232776 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, the conventional applicator containers have room for improvement in terms of improving the massage effect.

[0005] The present invention has been made in consideration of the above-mentioned circumstances, and aims to provide an application container that can apply the contents evenly and in appropriate amounts to the application area with little bias while improving the massage effect. [Means for solving the problem]

[0006] The present invention employs the following means to solve the above problems. That is, the application container of the present invention comprises a container body for accommodating contents, a topped cylindrical inner plug member fixed to the mouth of the container body and having a first top wall portion with a communication hole formed therein communicating with the inside of the container body, a topped cylindrical support member screwed to the inner plug member and having a second top wall portion with a plurality of support recesses formed therein for rotatably supporting each of a plurality of application balls, and a topped cylindrical inner plug member fixed to the support member and having a third top wall portion with a plurality of through holes formed therein for allowing each of the upper portions of the plurality of application balls to protrude upward. and a covering member, one of the multiple support recesses is a central support recess arranged coaxially with the central axis of the container body extending in the vertical direction, the second top wall portion is formed with a communication hole opening to a lower end portion on the inner surface of the central support recess and an opening / closing tube protruding downward from the opening peripheral portion of the communication hole on the underside of the second top wall portion, and the first top wall portion is formed with a stopper body that is releasably fitted into the lower end opening of the opening / closing tube and blocks communication between the communication hole and the inside of the opening / closing tube.

[0007] According to the present invention, since multiple application balls are provided, the multiple application balls can be pressed against the application part almost simultaneously to apply the contents. This makes it possible, for example, to make the application part such as the skin sink between the adjacent application balls or to reduce the pressing force against the application part during application, thereby improving the massage effect. Of the multiple support recesses, only the central support recess that is coaxial with the central axis of the container body can communicate with the container body through the communication hole, the opening and closing tube, and the communication hole, so that the contents can be applied to the application part evenly and in appropriate amounts with little bias. For example, if all of the multiple support recesses communicate with the container body, a large amount of the contents may be applied to the application part, and if only the support recesses other than the central support recess among the multiple support recesses communicate with the container body, it may be difficult to apply the contents evenly and with little bias to the application part. The stopper body of the inner plug member is releasably fitted into the lower end opening of the opening and closing tube in the support member, blocking communication between the communication hole and the inside of the opening and closing tube. Therefore, when the support member and covering member are raised relative to the inner plug member, the stopper body comes out of the lower end opening of the opening and closing tube, opening the lower end opening of the opening and closing tube, and communication between the inside of the container body and the inside of the central support recess is established. Meanwhile, in the waiting state before the support member and covering member are raised relative to the inner plug member, it is possible to prevent communication between the inside of the container body and the inside of the central support recess, thereby reliably preventing the contents in the container body from leaking.

[0008] The planar shape of the second top wall portion when viewed from the top or bottom direction may be a flat shape having a long axis and a short axis that intersect each other on the central axis, and the multiple support recesses may be provided on the second top wall portion at intervals in the long axis direction in which the long axis extends.

[0009] In this case, the second top wall portion, which has a flat shape when viewed from above and below, has multiple support recesses spaced apart in the longitudinal direction, so that the number of application balls can be reduced while effectively improving the massage effect.

[0010] The first top wall portion may have a bottomed, cylindrical inner tube inserted into the mouth portion, the communicating hole may penetrate the peripheral wall portion of the inner tube, the stopper body may protrude upward from the bottom wall portion of the inner tube, and the opening and closing tube may be tightly fitted into the inner tube so as to be able to slide vertically.

[0011] In this case, an inner insertion tube having a communicating hole and a stopper body is formed in the first top wall portion, and the opening and closing tube is tightly fitted into the inner insertion tube so that it can slide vertically, thereby reliably preventing communication between the inside of the container body and the inside of the central support recess in the above-mentioned standby state. Effect of the Invention

[0012] According to this invention, the contents can be applied to the application area evenly and in appropriate amounts with little bias while improving the massage effect. [Brief description of the drawings]

FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 and 2, the application container 1 includes a container body 11 in which the contents are accommodated, an inner plug member 12, a support member 13, a covering member 14, and an overcap 15. The contents include, for example, cosmetics such as emulsion and lotion.

[0015] The container body 11 is formed in a cylindrical shape having a mouth 11a and an open bottom, and the inner plug member 12, the support member 13, the covering member 14, and the overcap 15 are formed in a cylindrical shape with a top. The container body 11, the inner plug member 12, the support member 13, the covering member 14, and the overcap 15 are arranged coaxially with a common axis. Hereinafter, this common axis will be referred to as the central axis O, the direction along the central axis O will be referred to as the up-down direction, the mouth 11a side of the container body 11 along the central axis O will be referred to as the upper side, and the bottom side of the container body 11 will be referred to as the lower side. When viewed from the up-down direction, the direction intersecting the central axis O will be referred to as the radial direction, and the direction going around the central axis O will be referred to as the circumferential direction.

[0016] The container body 11 is a tube container formed by tube molding. After the contents are filled into the container body 11 from the open bottom, the bottom is crushed in the radial direction and sealed. For example, a bottomed cylindrical body having a body formed to be deformable by squeezing may be used as the container body 11. 3, the portion of the container body 11 located below the mouth portion 11a has a flattened shape in plan view from the top-bottom direction, with a major axis L1 and a minor axis L2 intersecting each other on the central axis O. In the illustrated example, the shape is an ellipse.

[0017] The inner plug member 12 includes a first peripheral wall portion 21 and a first top wall portion 22 .

[0018] The first peripheral wall portion 21 has a circular shape when viewed from the top and bottom. The mouth portion 11a of the container body 11 is fitted and fixed in the first peripheral wall portion 21. A male screw portion 21a is formed on the outer peripheral surface of the first peripheral wall portion 21. A first restricting protrusion 21b is formed on the outer peripheral surface of the first peripheral wall portion 21 at a portion located above the male screw portion 21a. The first restricting protrusion 21b extends continuously over the entire circumferential length. The first restricting protrusion 21b is provided at the upper end portion of the first peripheral wall portion 21. The radial outer end portion of the first restricting protrusion 21b is located radially inward from the radial outer end portion of the male screw portion 21a.

[0019] A shoulder cover 26 is formed at the lower end of the first peripheral wall portion 21, protruding radially outward and covering the shoulder portion 11b of the container body 11. The shoulder cover 26 has the same flat shape as the shoulder portion 11b when viewed from above. The shoulder cover 26 covers the entire shoulder portion 11b except for the outer peripheral edge portion. A locking tube 27 is formed at the outer peripheral edge portion of the shoulder cover 26, protruding downward. A locking protrusion 27a is formed on the outer peripheral surface of the locking tube 27, protruding radially outward and extending continuously over the entire circumferential length.

[0020] The first top wall portion 22 is formed with an inner tube 23 inserted into the mouth portion 11a of the container body 11. The inner tube 23 is formed in a bottomed cylindrical shape. The inner tube 23 is arranged coaxially with the central axis O. A communication hole 24 is formed in the peripheral wall portion of the inner tube 23, penetrating in the radial direction and communicating with the inside of the container body 11. The communication hole 24 penetrates the outer peripheral edge portion of the bottom wall portion of the inner tube 23 in the vertical direction. A plurality of communication holes 24 are formed in the inner tube 23 at intervals in the circumferential direction. A cylindrical plug body 25 protruding upward is formed in the bottom wall portion of the inner tube 23. The plug body 25 is arranged coaxially with the central axis O. The plug body 25 is located below the upper end of the communication hole 24.

[0021] The support member 13 includes a second peripheral wall portion 31 and a second top wall portion 32 .

[0022] The second peripheral wall portion 31 has a circular shape when viewed from the top-bottom direction. A female thread portion 31a that screws into the male thread portion 21a of the first peripheral wall portion 21 is formed on the inner peripheral surface of the second peripheral wall portion 31. As a result, the support member 13 is screwed to the inside plug member 12. A second restricting protrusion 31b is formed on the inner peripheral surface of the second peripheral wall portion 31 at a portion located above the female thread portion 31a. The second restricting protrusion 31b extends continuously over the entire length in the circumferential direction. The radial inner end of the second restricting protrusion 31b is located radially inward from the radial inner end of the female thread portion 31a. The second restricting protrusion 31b is located below the first restricting protrusion 21b of the inside plug member 12 and faces it in the top-bottom direction. The vertical gap between the second restricting projection 31b and the first restricting projection 21b is shorter than the vertical screw-in length between the male screw portion 21a of the inner plug member 12 and the female screw portion 31a of the support member 13. As a result, as shown in Fig. 4, the support member 13 rises relative to the inner plug member 12, and the second restricting projection 31b and the first restricting projection 21b are in contact with each other, and the screw-in between the male screw portion 21a and the female screw portion 31a is maintained.

[0023] A plurality of support recesses 33, 34 are formed on the upper surface of the second top wall portion 32, which rotatably support the plurality of application balls 16. The inner peripheral surfaces of the support recesses 33, 34 are formed in a concave spherical shape that opens on the upper surface of the second top wall portion 32, and extend along the outer peripheral surface of the spherical application ball 16. The application ball 16 protrudes upward from the upper surface of the second top wall portion 32. The upper surface of the second top wall portion 32 and the center of the application ball 16 are positioned at the same vertical position. The diameter of the application ball 16 is equal to or larger than half the size of the second top wall portion 32 along the minor axis direction in which the minor axis L2 extends.

[0024] One of the plurality of support recesses 33, 34 is provided coaxially with the central axis O. Hereinafter, this support recess will be referred to as a central support recess 33. The upper end of the application ball 16 supported in the central support recess 33 is located higher than the upper ends of the application balls 16 supported in the remaining end support recesses 34 excluding the central support recess 33 among the multiple support recesses 33, 34. The upper end of the application ball 16 supported in the central support recess 33 abuts against or is close to the lower surface of the top wall of the overcap 15.

[0025] The second top wall portion 32 is formed with a communication hole 35 that opens to the lower end of the inner circumferential surface of the central support recess 33, and an open / close tube 36 that protrudes downward from the opening periphery of the communication hole 35 on the lower surface of the second top wall portion 32. The communication hole 35 and the open / close tube 36 are disposed coaxially with the central axis O.

[0026] The opening and closing tube 36 is tightly fitted in the inner insertion tube 23 of the plug member 12 so as to be vertically slidable. The lower end opening edge of the opening and closing tube 36 abuts or is close to the upper surface of the bottom wall of the inner insertion tube 23. The plug body 25 of the inner plug member 12 is removably fitted into the lower end opening of the opening and closing tube 36. This allows the communication between the inside of the opening and closing tube 36 and the communication hole 24 of the inner insertion tube 23 to be releasably blocked. The fitting length of the opening and closing tube 36 and the inner insertion tube 23 in the vertical direction is longer than the gap between the second restricting protrusion 31b and the first restricting protrusion 21b in the vertical direction. As a result, as shown in FIG. 4, the support member 13 rises relative to the plug member 12, and the fitting of the opening and closing tube 36 into the inner insertion tube 23 is maintained in a state in which the second restricting protrusion 31b and the first restricting protrusion 21b abut.

[0027] The planar shape of the second top wall portion 32 is the same flat shape as the planar shape of the portion of the container body 11 located below the mouth portion 11a. When viewed from the top-bottom direction, the size of the second top wall portion 32 is smaller than the size of the shoulder portion 11b of the container body 11. The second top wall portion 32 protrudes outward in the long axis direction in which the long axis L1 extends from the second peripheral wall portion 31. An outer tube portion 37 protruding downward is formed on the outer peripheral edge of the second top wall portion 32. The lower end opening edge of the outer tube portion 37 abuts or is close to the upper surface of the shoulder cover 26 of the inside plug member 12. The radial gap between the inner peripheral surface of the outer tube portion 37 and the outer peripheral surface of the second peripheral wall portion 31 disappears at the end in the short axis direction, and the outer tube portion 37 and the second peripheral wall portion 31 are integrated at the end in the short axis direction.

[0028] The multiple support recesses 33, 34 are provided at intervals in the long axis direction on the second top wall portion 32. The multiple support recesses 33, 34, except for the central support recess 33, are provided in equal numbers on both sides of the central support recess 33 in the long axis direction (one on each side in the illustrated example). The end support recesses 34 open on the long axis end face of the second top wall portion 32. The application ball 16 supported by the end support recess 34 protrudes outward in the long axis direction from the long axis end face of the second top wall portion 32. The center of the application ball 16 supported by the end support recess 34 is located inside the long axis direction of the long axis end face of the second top wall portion 32.

[0029] The covering member 14 includes a third peripheral wall portion 41 and a third top wall portion 42 . The planar shape of the covering member 14 is the same flat shape as the planar shape of the portion of the container body 11 that is located below the mouth portion 11a.

[0030] The third peripheral wall portion 41 is fitted onto the outer tube portion 37 of the support member 13. This fixes the covering member 14 to the support member 13. The upper portion of the third peripheral wall portion 41 has a smaller diameter as it extends upward. The outer peripheral surface of the portion of the third peripheral wall portion 41 that is located below the upper portion is located at the same radial position as the outer peripheral surface of the locking tube 27 of the shoulder cover 26 over the entire circumferential length. The lower end opening edge of the third peripheral wall portion 41 abuts against or is close to the upper surface of the shoulder cover 26 of the inside plug member 12.

[0031] The third top wall portion 42 covers the support recesses 33, 34 of the support member 13 from above. The lower surface of the third top wall portion 42 abuts or is close to the upper surface of the second top wall portion 32. The diameter of the application ball 16 is more than half the size of the third top wall portion 42 along the short axis direction. The third top wall portion 42 is formed with a plurality of through holes 43 that allow the upper portions of the application balls 16 to protrude upward separately. The inner peripheral surface of the through hole 43 is curved so as to follow the outer peripheral surface of the application ball 16 in a vertical cross section along the up-down direction. The through hole 43 faces the support recesses 33, 34 in the up-down direction. Among the plurality of through holes 43, the through holes 43 located at both ends in the long axis direction and facing the end support recesses 34 in the up-down direction are opened on the end surface in the long axis direction of the third top wall portion 42. The application ball 16 supported in the end support recess 34 protrudes outward in the long axis direction from the long axis end face of the third top wall portion 42. The center of the application ball 16 supported in the end support recess 34 is located inward in the long axis direction from the long axis end face of the third top wall portion 42. The gap in the long axis direction between adjacent application balls 16 in the long axis direction on the upper surface of the third top wall portion 42 is equal to or smaller than the radius of the application ball 16.

[0032] The overcap 15 integrally covers the application ball 16, the covering member 14, and the locking tube 27 of the shoulder cover 26. The upper end of the application ball 16 supported by the central support recess 33 abuts against or is close to the lower surface of the top wall of the overcap 15. A locking projection 15a is formed on the inner peripheral surface of the lower end of the overcap 15, protruding radially inward and extending continuously over the entire circumferential length. The locking projection 15a is detachably fitted to the locking projection 27a of the shoulder cover 26 by undercut. The planar shape of the overcap 15 is the same flat shape as the planar shape of the portion of the container body 11 that is located below the mouth portion 11a. The outer peripheral surface of the overcap 15 is located at the same radial position as the outer peripheral edge of the outer peripheral surface of the shoulder portion 11b of the container body 11 over the entire circumferential length. The lower end opening edge of the overcap 15 abuts against or is close to the outer circumferential edge of the outer circumferential surface of the shoulder portion 11b of the container body 11.

[0033] Next, the operation of the application container 1 configured as above will be described.

[0034] First, the overcap 15 is lifted up relative to the container body 11 to release the undercut engagement between the locked projection 15a of the overcap 15 and the locking projection 27a of the shoulder cover 26. This causes the overcap 15 to be removed from the locking tube 27 of the shoulder cover 26, exposing the application ball 16 and the covering member 14. Next, when the third peripheral wall portion 41 of the covering member 14 is operated to rotate it together with the support member 13 around the central axis O relative to the inner plug member 12, the male thread portion 21a of the inner plug member 12 and the female thread portion 31a of the support member 13 screw together, causing the covering member 14 and the support member 13 to rise relative to the inner plug member 12. As a result, as shown in Fig. 4, the lower end opening of the opening / closing tube 36 of the support member 13 is disengaged upward from the plug body 25 and opened, and the inside of the container body 11 communicates with the inside of the central support recess 33 through the communication hole 24, the inside of the inner insertion tube 23, the inside of the opening / closing tube 36, and the communication hole 35. Then, while the contents in the container body 11 are being supplied into the central support recess 33, the application ball 16 is pressed against the part to be coated and the application container 1 is moved along the surface of the part to be coated, thereby rotating the application ball 16 and applying the contents to the part to be coated.

[0035] Here, when the covering member 14 and the supporting member 13 are rotated approximately 180° around the central axis O relative to the inner plug member 12 and raised, the second regulating protrusion 31b of the supporting member 13 abuts against the first regulating protrusion 21b of the inner plug member 12, thereby regulating the raising of the covering member 14 and the supporting member 13 relative to the inner plug member 12.

[0036] As described above, according to the application container 1 of this embodiment, since a plurality of application balls 16 are provided, the contents can be applied by pressing the plurality of application balls 16 against the part to be applied almost simultaneously. This makes it possible, for example, to make the part to be applied, such as the skin, sink between the adjacent application balls 16 during application, or to reduce the pressing force against the part to be applied, thereby improving the massage effect.

[0037] Of the multiple support recesses 33, 34, only the central support recess 33, which is arranged coaxially with the central axis O, is capable of communicating with the inside of the container body 11 through the communication hole 35, the opening and closing tube 36, and the communication hole 24, so that the contents can be applied evenly and in appropriate amounts to the application area with little bias. For example, if all of the multiple support recesses 33, 34 are connected to the inside of the container body 11, there is a risk that a large amount of contents will be applied to the coated portion, and if only the end support recess 34 is connected to the inside of the container body 11, it may become difficult to apply the contents evenly to the coated portion with little bias.

[0038] The stopper body 25 of the inner plug member 12 is releasably fitted into the lower end opening of the open-close tube 36 of the support member 13, and communication between the communication hole 24 and the inside of the open-close tube 36 is blocked. Therefore, when the support member 13 and the covering member 14 are raised relative to the inner plug member 12, the stopper body 25 comes out of the lower end opening of the open-close tube 36, the lower end opening of the open-close tube 36 is opened, and communication between the inside of the container body 11 and the inside of the central support recess 33 is established. Meanwhile, in the waiting state before the support member 13 and the covering member 14 are raised relative to the inner plug member 12, it is possible to prevent communication between the inside of the container body 11 and the inside of the central support recess 33, thereby reliably preventing the contents in the container body 11 from leaking.

[0039] The second top wall portion 32 has a flat shape when viewed from above and below, and a plurality of support recesses 33, 34 are provided at intervals in the longitudinal direction, so that the number of application balls 16 can be reduced while effectively improving the massage effect.

[0040] An inner insertion tube 23 having a communication hole 24 and a stopper body 25 is formed in the first top wall portion 22, and the opening / closing tube 36 is tightly fitted into the inner insertion tube 23 so as to be able to slide vertically, so that communication between the inside of the container body 11 and the inside of the central support recess 33 can be reliably prevented in the above-mentioned standby state.

[0041] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0042] In the above embodiment, the planar shapes of the portion of the container body 11 located below the mouth portion 11a, the second top wall portion 32, the covering member 14, and the overcap 15 are each elliptical, but these may be appropriately changed, for example to a circular or angular shape. The support member 13 does not necessarily have to have the outer cylinder portion 37 . The number of each of application balls 16, supporting recesses 33, 34, and through holes 43 may be four or more.

[0043] In addition, within the scope of the invention, the components in the above-described embodiments may be replaced with well-known components as appropriate, and the above-described embodiments and the above-described variations may be combined as appropriate. [Explanation of symbols]
