TECHNICAL FIELD

Application containers and application tools.

BACKGROUND

Japanese Unexamined Patent Publication No. 10-174613 discloses a liquid cosmetic material application container for accommodating a liquid cosmetic material. The liquid cosmetic material application container includes a main body having an application tool, and a lid body having a tank filled with the liquid cosmetic material to be adhered to the application tool. A male screw is formed on an outer surface of the main body, and a female screw is formed on an inner surface of the lid body. The male screw is screwed into the female screw, thereby attaching the main body to the lid body.

An opening of the tank in the lid body has a cylindrical sealing member for sealing the tank. The sealing member includes a flange portion protruding outward in a radial direction. The sealing member is fixed to an interior of the lid body by interposing the flange portion between the opening of the tank and a compression coil spring. The sealing member is made of synthetic rubber, and internally has a through-hole having a substantially funnel shape. The application tool of the main body is inserted into the through-hole. In addition, if the application tool is inserted into the through-hole, an application tool holder located in a base of the application tool comes into contact with an outer edge of the through-hole. The through-hole is sealed with the sealing member by the application tool holder coming into contact with the outer edge of the through-hole.

Japanese Unexamined Patent Publication No. H9-70314 discloses a liquid cosmetic material application container. The liquid cosmetic material application container includes a hollow shaft cylinder whose leading end has an application tool and which extends in a bar shape, and a lid body that can be attached to the shaft cylinder by covering the application tool. In the liquid cosmetic material application container, a female screw formed on an inner surface of the lid body is screwed to a male screw formed on an outer surface of the shaft cylinder, thereby attaching the lid body to the shaft cylinder.

The lid body includes a cartridge-type tank for accommodating the liquid cosmetic material, and a cylindrical body combined with the cartridge-type tank. The application tool is inserted into the cartridge type tank. The cylindrical body internally has a liquid cosmetic material sealing member serving as a synthetic rubber-made packing having a small hole into which the application tool is inserted. The liquid cosmetic material sealing member includes a peripheral ridge and a flange portion which are formed on an outer peripheral surface. The peripheral ridge of the liquid cosmetic material sealing member engages with a peripheral groove of the cartridge-type tank, and the flange portion is biased against the cartridge-type tank side by a compression coil spring. Thereby the liquid cosmetic material sealing member is fixed to an interior of the cylindrical body.

SUMMARY

The liquid cosmetic material sealing member functions as a cylindrical wiper which wipes off a liquid cosmetic material excessively adhering to the application tool when the application tool is pulled out from the tank. The peripheral ridge of the wiper engages with the peripheral groove of the tank, and the flange portion is biased against the tank side by the compression coil spring. In a case where the wiper is biased against the tank side by the compression coil spring, and since the wiper is formed of a soft material such as synthetic rubber, when a force acting in an axial direction is applied to the wiper, the wiper is deformed. Consequently, there is a possibility that the wiper may fall into the tank. In this way, when the force is applied to the wiper in the axial direction, the wiper may be detached.

Example application containers which can prevent a wiper from being detached are disclosed herein.

An example application container includes a cylindrical shaped filling unit having a closed bottom in one end and that has an opening in the other end in an axial direction, and a cover that has a cylindrical shape for accommodating the filling unit, and that has a female screw formed on one end side of an inner surface in the axial direction. Additionally, the application container may include a main body that has an application tool to be inserted into the filling unit, and a male screw to be screwed into the female screw, and a soft material-made wiper to be fixed to the opening of the filling unit and the inner surface of the cover. The wiper has a first protruding portion which protrudes outward in a radial direction. The first protruding portion is interposed in the axial direction between a wall portion to be disposed on the inner surface of the cover and an end portion on the opening side of the filling unit.

In the application container, the cylindrical filling unit having the opening in the end in the axial direction is accommodated in the cylindrical cover, thereby appearing as a double cylindrical shape. The female screw is formed on the one end side of the inner surface of the cover in the axial direction, and the male screw is formed in the main body having the application tool to be inserted into the filling unit. In a state where the application tool is inserted into the filling unit, the male screw of the main body is screwed into the female screw of the inner surface of the cover, thereby mounting the main body on the cover. The soft material-made wiper is fixed to the opening of the filling unit and the inner surface of the cover. The wiper includes the first protruding portion which protrudes outward in the radial direction. In addition, the inner surface of the cover has the wall portion, and the first protruding portion of the wiper is interposed in the axial direction between the wall portion and the end portion on the opening side of the filling unit. The first protruding portion is fixed in an interposed state in the axial direction between the wall portion of the inner surface of the cover and the end portion on the opening side of the filling unit. Therefore, the first protruding portion of the wiper is interposed in the axial direction between the wall portion of the inner surface of the cover and the end portion of the filling unit. Accordingly, a configuration can be adopted in which a force acting in the axial direction is less likely to be applied to the first protruding portion of the wiper. As a result, a position of the wiper may be prevented from being misaligned with the inner surface of the cover and the filling unit. Therefore, the wiper may be prevented from being detached.

The wiper may have a second protruding portion which protrudes in the axial direction from a surface on the wall portion side. In this case, the second protruding portion enters the wall portion in the axial direction. Therefore, the second protruding portion may be prevented from slipping out of the wall portion. Accordingly, the wiper may be reliably prevented from being detached.

A plurality of the wall portions may be disposed on the inner surface of the cover along a circumferential direction. In this case, the first protruding portion of the wiper can be interposed between a plurality of the wall portions and the end portion of the filling unit. Therefore, even in a case where a plurality of the wall portions are intermittently formed along the circumferential direction, the wiper may be reliably prevented from being detached.

The application container may further include a bar-shaped application material that extends in the axial direction on a side opposite to the application tool of the main body. The main body may include a feeding mechanism which feeds the bar-shaped application material in the axial direction. In this case, the filling unit is internally filled with a liquid or powder application material, and the application container includes the bar-shaped application material. Accordingly, one application container can be provided with a plurality of application material types. The main body includes the feeding mechanism which feeds the bar-shaped application material on the side opposite to the application tool of the main body. In this manner, the bar-shaped application material can be fed to the side opposite to the application tool.

Accordingly, the wiper may be prevented from being detached.

DETAILED DESCRIPTION

Hereinafter, embodiments of an application container will be described with reference to the drawings. In describing the drawings, the same reference numerals will be given to the same or equivalent elements, and repeated description will be appropriately omitted.

First Group of Embodiments

FIGS. 1 and 2illustrate an external view of an application container1according to a first group of embodiments having an overall shape which is an elongated round bar shaped like a writing tool. A cap C is attached thereto. The application container1includes a solid bar-shaped application material M. For example, the bar-shaped application material M is a bar-shaped cosmetic material, but may be a drawing material. In some examples, the bar-shaped application material M may be an eyebrow pencil. In the example illustrated inFIGS. 1 and 2, the application container1is an eyebrow feeding container.

For example, the application container1includes a main body2to which the cap C is attached, and an accommodation portion10which may be attached to a side opposite to the cap C of the main body2and accommodating the application material A. The application material A may be a powder or liquid application material. For example, the application material A may include a liquid or powder used for an eyeliner, an eye color, an eyebrow cosmetic, a mascara, a concealer, a lip color, or a hair color. Alternatively, the application material A may include a liquid or powder used for stationery goods including a writing tool, a correction fluid, or an adhesive.

In the application container1, the cap C, the main body2, and the accommodation portion10are arranged side by side along an axial direction in which an axis L of the application container1extends. In the description herein, an “axis” indicates a center line extending forward to and rearward from the application container1. An “axial direction” is a forward-rearward direction, and indicates a direction along the axis L. A feeding direction of the bar-shaped application material M is defined as a forward direction (forward moving direction), and a direction opposite thereto is defined as a rearward direction.

FIG. 3is a side view illustrating the application container1from which the cap C is removed.FIG. 4is a side view illustrating a state where the bar-shaped application material M is fed by removing the accommodation portion10from the application container1illustrated inFIG. 3.FIG. 5is a sectional view taken along line B-B inFIG. 4. As illustrated inFIGS. 3 to 5, the main body2includes a leading cylinder3forming a front portion of a container, a middle cylinder4disposed behind the leading cylinder3, and a coupling cylinder5forming a rear portion of the container disposed behind the middle cylinder4and exposed outward of the application container1. Additionally, the main body2may include an attachment member6extending rearward from the coupling cylinder5and to which the application tool P is attached, a moving body7accommodated inside the leading cylinder3, a holding member8for holding the moving body7inside the coupling cylinder5, and an application material holder9for holding the bar-shaped application material M on a front side of the moving body7. The leading cylinder3, the middle cylinder4, the coupling cylinder5, the moving body7, and the holding member8may be assembled together to form a feeding mechanism15which feeds the bar-shaped application material M in the axial direction.

The bar-shaped application material M has a side surface M3extending in the axial direction, and a leading end thereof has an inclined portion M1inclined with respect to the axial direction. A shape of the bar-shaped application material M when viewed from the front side is formed so that the inclined portion M1extends lengthwise or linearly in a uniform direction. In addition, a flat surface M2extending in a direction inclined with respect to the axial direction is formed between the inclined portion M1located in the leading end of the bar-shaped application material M and the side surface M3of the bar-shaped application material M. For example, a pair of the flat surfaces M2is disposed on both right and left sides with respect to the inclined portion M1. For example, each of the flat surfaces M2extends rearward from both sides of the inclined portion M1in a longitudinal direction. When the inclined portion M1and a pair of the flat surfaces M2are viewed from the front side, a shape thereof extends lengthwise or linearly in a uniform direction, and forms a rounded hexagonal shape.

For example, the leading cylinder3is molded using an ABS resin, and appears as an elongated cylindrical shape extending in the axial direction. An interior of the leading cylinder3serves as an accommodation space3nfor accommodating the bar-shaped application material M. A front end3cof the leading cylinder3has an inclined surface3ainclined with respect to the axial direction. An opening3bfrom which the bar-shaped application material M is exposed is formed in the front end3cof the leading cylinder3. The opening3bextends obliquely rearward from the front end3cof the leading cylinder3.

The leading cylinder3has a front side cylindrical portion3dfor accommodating the bar-shaped application material M, a stepped cylindrical portion3elocated behind the front side cylindrical portion3d, and a rear side cylindrical portion3flocated behind the stepped cylindrical portion3e. Among the front side cylindrical portion3d, the stepped cylindrical portion3e, and the rear side cylindrical portion3f, in some examples only the front side cylindrical portion3dis exposed outward. The front side cylindrical portion3dgradually decreases in diameter from a step3gtoward the front end3c. The step3gis formed between the front side cylindrical portion3dand the stepped cylindrical portion3e, and the front side cylindrical portion3dincreases in diameter from the step3gwith respect to the stepped cylindrical portion3e. A side behind the step3gof the leading cylinder3serves as an insertion portion to be inserted into the middle cylinder4from the front side. The side behind the step3gis inserted into the middle cylinder4. In this manner, the leading cylinder3engages with the middle cylinder4so as to be immovable in the axial direction and relatively rotatable.

FIG. 6is a sectional view in which the stepped cylindrical portion3eof the leading cylinder3is cut along a plane including the axial direction.FIG. 7Ais a partial sectional view of the leading cylinder3.FIG. 7Bis a side view of the leading cylinder3. As illustrated inFIGS. 6, 7A, and 7B, inside the front side cylindrical portion3dof the leading cylinder3, the accommodation space3nfor accommodating the bar-shaped application material M extends along the axial direction. A shape of the accommodation space3nwhen viewed along the axial direction is a non-circular shape. For example, the shape extends lengthwise or linearly in a uniform direction. A projection portion3rextending in the axial direction is disposed inside the front side cylindrical portion3dof the leading cylinder3. For example, a pair of the projection portions3ris disposed along the radial direction of the leading cylinder3.

A front end of the projection portion3rleads to the vicinity of the opening3bof the leading cylinder3, and the front end of the projection portion3rhas an inclined surface3pwhich protrudes by being curved inward of the leading cylinder3as the inclined surface3pis oriented rearward. An outer surface of the stepped cylindrical portion3eof the leading cylinder3has an annular recess portion3hextending in the circumferential direction of the leading cylinder3, and a recess portion3jlocated behind the annular recess portion3h. When the leading cylinder3is manufactured by means of molding, an injection port for injecting a resin material into a molding die may be located at the center of the recess portion3j. In some examples, a pair of the recess portions3jis disposed along the radial direction of the leading cylinder3, and each of the recess portions3jhas a rectangular shape.

A ridge3kextending in the axial direction is disposed inside the stepped cylindrical portion3eof the leading cylinder3. For example, a plurality of the ridges3kare disposed therein. Each of the ridges3kextends from the rear side of the stepped cylindrical portion3eto an inner surface of the rear side cylindrical portion3f. For example, a pair of the ridges3kis disposed along the radial direction of the leading cylinder3. The rear side of the accommodation space3nfor accommodating the bar-shaped application material M has a tapered surface3minclined rearward as the tapered surface3mis oriented inward in the radial direction.

The rear side of the ridge3kserves as an internal space3qof the rear side cylindrical portion3f, and the internal space3qhas a larger diameter than a portion having the ridge3k. The rear side cylindrical portion3fincludes an elastic protruding portion3tat a pair of positions facing each other on an inner peripheral surface3sthereof. The elastic protruding portion3tcomes into contact with the inner surface of the middle cylinder4by using an elastic force, and is disposed so as to protrude outward in the radial direction. A notch3uallowing the inside and the outside of the leading cylinder3to communicate with each other is formed around the elastic protruding portion3t. The elastic protruding portion3tis caused to have elasticity in the radial direction by the notch3u.

The notch3uincludes a pair of slits3vand3wwhich are arranged side by side at a plurality of positions along the circumferential direction of the leading cylinder3and which extend in the axial direction. Additionally, the notch3uincludes a slit3xdrilled on the front side of the elastic protruding portion3tand extending in the circumferential direction of the leading cylinder3between the slits3vand3w. A portion surrounded by the notch3uin the rear side cylindrical portion3fforms an arm3ywhich is flexible in the radial direction. Accordingly, the elastic protruding portion3tlocated on the outer surface of the leading end portion of the arm3yhas an elastic force (biasing force) acting in the radial direction.

The annular projection4qon the inner surface of the middle cylinder4may be configured to engage with the stepped cylindrical portion3eof the leading cylinder3in the axial direction so that the stepped cylindrical portion3eand the annular projection4qare relatively rotatable, and the elastic protruding portion3tcomes into contact with the inner surface of the middle cylinder4.FIG. 8Ais a side view illustrating the middle cylinder4, andFIG. 8Bis a side view when the middle cylinder4is viewed in a rotational position different from that inFIG. 8A. In some examples, the middle cylinder4is molded using polyacetal (POM), and is formed into a substantially cylindrical shape.

As illustrated inFIGS. 8A and 8B, the middle cylinder4includes a front side cylindrical portion4a, a rear side cylindrical portion4b, and a spring portion4cin this order from the front end toward the rear end. The middle cylinder4softens an impact internally transmitted when an external force is applied such as during falling, thereby protecting the application container1or the bar-shaped application material M. The spring portion4cof the middle cylinder4has a function to screw back the screw portion20when a clutch is rotated up to the rearward movement limit of the bar-shaped application material M. The front end portion on the outer peripheral surface of the front side cylindrical portion4ahas an inclined surface4fwhich gradually increases in diameter as the inclined surface4fis oriented rearward. The outer peripheral surface of the front side cylindrical portion4ahas a protruding portion4dextending in the axial direction, and a projection4eprotruding in a substantially circular shape behind the protruding portion4d. The cap C engages with the protruding portion4dand the projection4e.

A flange portion4gprotruding outward in the radial direction and entering the front end of the coupling cylinder5is disposed between the front side cylindrical portion4aand the rear side cylindrical portion4b. The outer surface of the rear side cylindrical portion4bhas an annular projection4jhaving an inclined surface4hwhich decreases in diameter in the rearward direction, a plurality of protruding portions4kextending in the axial direction behind the annular projection4jand that are arranged side by side along the circumferential direction of the middle cylinder4, and a recess portion4mrecessed between a plurality of the protruding portions4k. When the middle cylinder4is manufactured by means of molding, an injection port for injecting a resin material such into a molding die may be located at the center of the recess portion4m. The spring portion4cis disposed behind the protruding portion4kand the recess portion4m. The spring portion4cis a resin spring which is stretchable in the axial direction. The spring portion4cis formed to have a main body portion4nand a slit4pwhich spirally extends along a peripheral surface of the main body portion4nand which allows the inside and the outside of the main body portion4nto communicate with each other. The spring portion4csoftens an impact by compressing when an external force is applied thereto.

As illustrated inFIGS. 2 and 5, in the middle cylinder4, a portion on the rear side of the front side cylindrical portion4ais inserted into the front side of the coupling cylinder5. In addition, in the middle cylinder4, the annular projection4jengages with the annular recess portion5adisposed on the inner surface of the coupling cylinder5in the axial direction, and the flange portion4gfits into the recess portion5bin the front end of the coupling cylinder5. A knurling tool5cfor engaging with the middle cylinder4in the rotation direction is disposed on the rear side of the annular recess portion5aof the coupling cylinder5. The knurling tool5cis formed in a shape where a plurality of irregularities are arranged side by side along the circumferential direction and the respective irregularities extend in the axial direction. The protruding portion4kof the middle cylinder4engages with the knurling tool5cin the rotation direction. In this manner, the middle cylinder4engages with the coupling cylinder5so as to be synchronously rotatable.

For example, the coupling cylinder5is molded using an ABS resin, and is formed in a cylindrical shape. The outer surface of the coupling cylinder5serves as a smooth surface having no irregularities. In some examples, the outer surface is an inclined surface5dwhich gradually increases in diameter in a rearward direction. The holding member8and the middle cylinder4are accommodated on the front side of the coupling cylinder5, and the attachment member6is accommodated on the rear side of the coupling cylinder5. The coupling cylinder5includes a partition wall5ewhich partitions the interior of the coupling cylinder5in the vicinity of the center in the axial direction. The holding member8and the middle cylinder4are inserted forward of the partition wall5e, and the attachment member6is inserted rearward of the partition wall5e.

The partition wall5ehas a protruding portion5gprotruding inward in the radial direction of the coupling cylinder5from the inner surface5fof the coupling cylinder5, a recess portion5hrecessed rearward from an end portion inside the protruding portion5gin the radial direction, and a through-hole5jpenetrating in the axial direction on a bottom surface of the recess portion5h. The inner surface of the recess portion5hhas a knurling tool5kin which a plurality of irregularities are arranged side by side along the circumferential direction and the respective irregularities extend in the axial direction. The inner surface5fon the rear side of the partition wall5ehas a larger diameter than the inner surface5fon the front side of the partition wall5e.

For example, the holding member8is molded using a POM, and is formed into a substantially cylindrical shape. The holding member8has a front side cylindrical portion8aextending in the axial direction, a flange portion8bwhich increases in diameter in the rear end of the front side cylindrical portion8a, and a rear side cylindrical portion8cengaging with the knurling tool5kof the recess portion5hof the coupling cylinder5, which is a rear side portion of the flange portion8b. The inner surface of the front end portion of the front side cylindrical portion8ahas a spiral projection8dforming one side of the screw portion20(described in further detail later).

The flange portion8bof the holding member8is interposed between the protruding portion5gof the partition wall5eof the coupling cylinder5and the rear end of the middle cylinder4. The rear side cylindrical portion8cof the holding member8includes an elastic protruding portion8e. The elastic protruding portion8eengages with the knurling tool5kof the coupling cylinder5in the rotation direction, and is disposed so as to protrude outward in the radial direction. A notch8fwhich allows the inside and the outside of the holding member8to communicate with each other is formed around the elastic protruding portion8e. The notch8fcauses the elastic protruding portion8eto be elastic in the radial direction. For example, a configuration of the notch8fmay be similar to a configuration of the notch3uof the leading cylinder3.

In some example holding members8, the rear side cylindrical portion8cis inserted into the recess portion5hof the partition wall5efrom the front side, and the elastic protruding portion8eengages with the knurling tool5kof the recess portion5hin the rotation direction. The elastic protruding portion8eand the knurling tool5kenable the holding member8to be synchronously rotatable around the axis with respect to the coupling cylinder5, and can release the synchronous rotation when a prescribed or greater rotational force (torque) is applied thereto. Since the synchronous rotation is released, the bar-shaped application material M reaches a forward movement limit, and a screwing operation of the screw portion20is stopped. Thereafter, the leading cylinder3or the middle cylinder4may be prevented from being disassembled due to a force of relatively rotating the leading cylinder3and the coupling cylinder5. In addition, in the holding member8, the flange portion8bis interposed between the partition wall5eand the middle cylinder4in the axial direction. In this manner, the holding member8engages with the coupling cylinder5so as to be linearly immovable in the axial direction and synchronously rotatable. In addition, the moving body7is inserted into the front side cylindrical portion8aof the holding member8.

FIG. 9Ais a front view when the moving body7is viewed from the front side, andFIG. 9Bis a side view of the moving body7. In some examples, the moving body7is molded using a POM, and is formed into a round bar shape. The moving body7includes a connector7adisposed on the front side and connected to the application material holder9, and a shaft body portion7bextending rearward from the connector7a. The outer surface of the connector7aand the outer surface of the shaft body portion7bhave a groove portion7cextending in the axial direction. The groove portion7cfunctions as a detent for the moving body7against the leading cylinder3, together with the ridge3kdisposed on the inner surface of the leading cylinder3. For example, a pair of the groove portions7cis disposed in the radial direction of the moving body7.

The front end of the connector7aof the moving body7has a tapered surface7dwhich increases in diameter in the rearward direction. The connector7ahas an annular projection7fhaving a tapered surface7ewhich gradually increases in diameter in the rearward direction behind the tapered surface7d, and an enlarged diameter portion7ghaving a larger diameter than the annular projection7fbehind the annular projection7f. A portion between the annular projection7fand the enlarged diameter portion7gserves as a reduced diameter portion7hwhich has a decreased diameter relative to the annular projection7fand the enlarged diameter portion7g.

The shaft body portion7bis a shaft body extending from the rear end of the connector7ain the axial direction. The outer surface of the shaft body portion7bhas a male screw7jforming the other one of the screw portion20. The male screw7jis formed throughout the axial direction of the shaft body portion7b. In some examples, the annular projection7fis inserted into the application material holder9, and the front end of the enlarged diameter portion7gcomes into contact with the rear end of the application material holder9. In this manner, the moving body7engages with the application material holder9in the axial direction. The groove portion7cof the moving body7engages with the ridge3kwhich is formed on the inner surface of the leading cylinder3in the rotation direction. The moving body7is inserted into the front side of the holding member8, and the male screw7jis screwed to the projection8dof the holding member8forming one side of the screw portion20.

FIG. 10Ais a side view illustrating the application material holder9.FIG. 10Bis a front view when the application material holder9is viewed from the front side. The application material holder9is a core chuck push bar internally inserted into the leading cylinder3so as to hold the bar-shaped application material M. For example, a material of the application material holder9is polybutylene terephthalate (PBT). As illustrated inFIGS. 10A and 10B, the application material holder9includes a gripper9alocated on the front side so as to grip the bar-shaped application material M, and a support portion9bextending rearward from the gripper9aand supporting the moving body7. A shape of the application material holder9when viewed along the axial direction is a non-circular shape. For example, the application material holder9has a rectangular shape in which corner portions are rounded and which extends lengthwise in one direction.

The gripper9aincludes a base portion9cforming a connector between the gripper9aand the support portion9b, and a plurality of arms9dextending forward from the base portion9cand gripping the bar-shaped application material M. The bar-shaped application material M is gripped inside a plurality of the arms9d. The inner surface of the respective arms9dhas a protruding portion9eextending in the axial direction along the arm9d. Each protruding portion9efits into the bar-shaped application material M, thereby allowing the bar-shaped application material M to be properly held by the application material holder9.

A shape of each protruding portion9ewhen viewed along the axial direction is a triangular shape whose leading end is rounded. Each arm9ddecreases in thickness in a forward direction. In some examples, each arm9dhas a first inclined surface9gand a second inclined surface9jsequentially forward from the base portion9c. One or more portions of the application material holder9may extend in the axial direction. For example, a portion between the base portion9cand the first inclined surface9gof the atm9d, a portion between the first inclined surface9gand the second inclined surface9jof the atm9d, and a portion between the second inclined surface9jand the front end9kof the arm9dmay extend in the axial direction.

The thickness of the arm9dbetween the base portion9cand the first inclined surface9gis greater than the thickness of the arm9dbetween the first inclined surface9gand the second inclined surface9j. The thickness of the arm9dbetween the first inclined surface9gand the second inclined surface9jis greater than the thickness of the atm9dbetween the second inclined surface9jand the front end9k. The height of the protruding portion9eof the arm9dis constant along the axial direction. Accordingly, a protruding height of the protruding portion9erelative to a top surface of the first inclined surface9gis lower than a protruding height of the protruding portion9erelative to a top surface of the second inclined surface9j.

The support portion9bof the application material holder9extends from the base portion9cto a side opposite to the gripper9a(rearward), thereby forming a cylindrical shape having a closed bottom, for example. The support portion9bhas a recess portion9qdisposed on an outer surface thereof, a window portion9rwhich allows the inside and the outside of the support portion9bto communicate with each other, and a through-hole9sdisposed in the rear end of the application material holder9and penetrating the application material holder9in the axial direction. An injection port for injecting a resin material into a molding die when the application material holder9is manufactured by means of molding may be located at the center of the recess portion9q. The rear end portion of the through-hole9shas a tapered surface9twhich increases in diameter in a rearward direction. In some examples, the recess portion9qhas a circular shape, and the window portion9rhas a rectangular shape extending lengthwise in the axial direction. The window portion9rand the through-hole9scommunicate with each other. The through-hole9swhen viewed from the rear has a circular shape.

In the application material holder9, the moving body7is inserted into the through-hole9sfrom behind. Additionally, the annular projection7fof the moving body7rides over the inner surface of the through-hole9sin the window portion9r. The annular projection7ffits into the window portion9r, and is exposed outward from the window portion9r. In this manner, the application material holder9engages with the moving body7so as to be immovable in the axial direction. The application material holder9having the non-circular shape enters the accommodation space3nhaving the non-circular shape of the leading cylinder3. In this manner, the application material holder9engages with the leading cylinder3in the rotation direction, and is synchronously rotated together with the leading cylinder3.

The attachment member6is inserted into the rear side of the partition wall5eof the coupling cylinder5.FIG. 11Ais a side view illustrating the attachment member6, andFIG. 11Bis a side view when the attachment member6is viewed from a rotational position different from that inFIG. 11A. The attachment member6may be formed of polypropylene (PP). As illustrated inFIGS. 11A and 11B, the attachment member6has a cylindrical shape which gradually decreases in diameter rearward from the front side. The attachment member6includes an insertion portion6alocated on the front side and inserted into the coupling cylinder5, and an attachment portion6bextending rearward from the insertion portion6aand having the application tool P attached to the leading end.

The insertion portion6ahas a stepped cylindrical shape. The outer surface of the insertion portion6ahas a knurling tool6cextending in the axial direction, a recess portion6ddisposed on the rear side of the knurling tool6c, an annular projection portion6fprotruding from the recess portion6dand having a tapered surface6eon the front side, and a flange portion6gwhich has a greater diameter behind the annular projection portion6f. The attachment portion6bincludes a large diameter portion6jhaving a male screw6hforming one side of a screw portion30for mounting the accommodation portion10on the main body2, and a small diameter portion6kextending rearward from the large diameter portion6jand to which the application tool P is attached.

Both the large diameter portion6jand the small diameter portion6khave a cylindrical shape extending in the axial direction. An enlarged diameter portion6rwhich increases in diameter from the outer surface of the attachment member6having the male screw6his disposed in front of the male screw6hof the large diameter portion6j. The enlarged diameter portion6ris disposed on the rear side of the flange portion6g. The height protruding outward in the radial direction of the enlarged diameter portion6ris lower than the height protruding outward in the radial direction of the flange portion6g. An inclined surface6mwhich gradually decreases in diameter from the large diameter portion6jtoward the small diameter portion6kis disposed between the large diameter portion6jand the small diameter portion6k.

The inclined surface6mhas an arc-shaped first bending portion6nhaving a center of rotation located inside in the radial direction of the attachment member6, an inclined portion6plocated on a side opposite to the large diameter portion6jof the first bending portion6n, and an arc-shaped second bending portion6qhaving a center of rotation located outside in the radial direction of the attachment member6. The first bending portion6n, the inclined portion6p, and the second bending portion6qare disposed in this order from the large diameter portion6jtoward the small diameter portion6k. An inclination angle of the inclined portion6pwith respect to the axial direction is 36°, for example.

As illustrated inFIGS. 2 and 5, the attachment member6internally has a space6v, and the space6vaccommodates a stirring member S for stirring the application material A. For example, a material of the stirring member S is SUS. However, the material may be a resin, and may be appropriately changed. The stirring member S is accommodated in a portion on the front side from the inclined surface6mon the inner surface of the attachment member6. For example, the stirring member S is a ball, and is formed into a spherical shape. The stirring member S emits sound by moving inside the space6vin accordance with vibrations applied to the application container1. The small diameter portion6kof the attachment portion6bextends rearward from the inclined surface6m. The rear end of the small diameter portion6khas an opening6sinto which the application tool P is inserted.

In the attachment member6, the insertion portion6ais inserted into the coupling cylinder5from behind, and the knurling tool6cengages with the ridge5mon the inner surface of the coupling cylinder5in the rotation direction. The annular projection portion6fengages with the annular projection portion5qon the inner surface of the coupling cylinder5in the axial direction. In this manner, the attachment member6engages with the coupling cylinder5so as to be immovable in the axial direction and non-rotatable. Then, the flange portion6gof the attachment member6enters the annular recess portion5pformed in the rear end of the coupling cylinder5.

The application tool P has a round bar shape, and has an inclined surface P1in one end in the longitudinal direction. The inclined surface P1is disposed in the rear end of the main body2, and is inclined so as to form an acute angle with respect to the axial direction. For example, the inclined surface P1has a flat shape. The application tool P has a large diameter portion P2having the inclined surface P1and a small diameter portion P3extending forward from the large diameter portion P2. The small diameter portion P3is inserted into the opening6sof the attachment member6. The outer surface of the small diameter portion P3has an annular projection portion P5which causes the application tool P to engage with the attachment member6and which has a tapered surface on the front side. In the application tool P, the small diameter portion P3is inserted into the opening6sof the attachment member6from the rear side, and the annular projection portion P5rides over the annular projection portion inside the opening6sso as to move forward. In this manner, the application tool P engages with the attachment member6in the axial direction.

Next, the accommodation portion10attached to the attachment member6and accommodating the application material A will be described in additional detail. The accommodation portion10includes a cylindrical filling unit11having a closed bottom and filled with the application material A, a cover12surrounding the filling unit11and attached to the attachment member6, and a soft material-made wiper13which draws the application tool P and the small diameter portion6kof the attachment member6so as to wipe off the application material A excessively adhering to the application tool P and the small diameter portion6k.

FIG. 12is a side view illustrating the filling unit11. For example, the filling unit11is formed of PP. As illustrated inFIG. 12, the filling unit11is formed in a cylindrical shape. The inner surface of the filling unit11has no irregularities, and serves as a smooth surface. The inner surface of the filling unit11is configured to include an inner surface11asmoothly curved in a cylindrical hole shape, and a flat bottom surface11blocated in the rear end of the inner surface11a.

The front side of the outer surface of the filling unit11has no irregularities, and serves as the smooth surface. The filling unit11has an opening11hinto which the wiper13is inserted in one end11gon the front side. The rear side of the outer surface of the filling unit11includes an enlarged diameter portion11cprotruding outward in the radial direction in the rear end of the filling unit11, an annular projection portion11elocated in front of the enlarged diameter portion11cand having a tapered surface11don the front side, and a plurality of projection portions1if extending forward in the axial direction from the tapered surface11d. The rear end of the enlarged diameter portion11eis slightly rounded. In some examples, four of the projection portions11fare disposed therein. The four projection portions11fare disposed at an equal interval in the circumferential direction. For example, a protruding shape of the projection portion11fis an arc shape.

FIG. 13Ais a side view illustrating the wiper13, andFIG. 13Bis a view when the wiper13is viewed from the rear side.FIG. 14is a sectional view taken along line C-C illustrated inFIG. 13A. The wiper13is formed of a rubber material. The hardness of the wiper13may be set to a value within the range of 40 to 80 in accordance with a type A durometer regulated in JIS 6253 (method of obtaining hardness of vulcanized rubber and thermoplastic rubber). For example, the hardness may be set to 60.

As illustrated inFIGS. 13A, 13B, and 14, the wiper13has a stepped cylindrical shape. The wiper13includes a cylindrical extension portion13aextending rearward, a first protruding portion13bprotruding outward in the radial direction in the front end of the extension portion13a, a second protruding portion13cfurther protruding forward from the front end of the first protruding portion13b, and a drawing portion13dprotruding inward in the radial direction from the extension portion13aand the first protruding portion13b.

The extension portion13ahas a first side surface13eextending in the axial direction from the rear end of the first protruding portion13b, a first tapered surface13finclined inward in the radial direction of the wiper13from the rear end of the first side surface13e, a second side surface13gextending in the axial direction from the rear end of the first tapered surface13f, and a second tapered surface13hinclined inward in the radial direction of the wiper13from the rear end of the second side surface13g. The rear end of the second tapered surface13hcorresponds to the rear end of the wiper13.

The wiper13has a through-hole13rinto which the application tool P and the attachment member6are inserted, and the through-hole13rpenetrates the wiper13in the axial direction. The inner surface of the extension portion13aof the wiper13is configured to include an inner peripheral surface13jsmoothly curved in a cylindrical hole shape, and the drawing portion13dprotruding inward in the radial direction from the front end of the inner peripheral surface13j. The drawing portion13dincludes a first planar portion13klocated in the front end of the inner peripheral surface13j, a first extension portion13mextending inward in the radial direction from an end portion of the first planar portion13k, an annular portion13nlocated in the rear end of the first extension portion13m, an inner peripheral surface13pextending forward from the annular portion13n, and a bending portion13qextending from the front end of the inner peripheral surface13ptoward the first protruding portion13b.

The first planar portion13kextends inward in the radial direction from the front end of the inner peripheral surface13j. The first extension portion13mobliquely extends rearward and inward in the radial direction from an end portion of the first planar portion13k. The annular portion13nis formed in a flat shape in the rear end of the first extension portion13m. The inner peripheral surface13pextends forward and inward in the radial direction from an end portion of the annular portion13n. The bending portion13qfaces the first protruding portion13bfrom the front end of the inner peripheral surface13p, and is bent forward and outward in the radial direction so that the drawing portion13dbulges. The application tool P and the attachment member6which are to be inserted into the through-hole13rcome into contact with the bending portion13qand the inner peripheral surface13p, and move rearward. The attachment member6and the application tool P which are drawn forward from the through-hole13rare drawn while both of these mainly come into contact with the inner peripheral surface13p. In this manner, both the attachment member6and the application tool P are drawn by the wiper13.

The first protruding portion13bhas a protruding surface13sextending outward in the radial direction from the front end of the extension portion13a, an outer peripheral surface13textending forward from an end portion of the protruding surface13soutside in the radial direction, and a tapered surface13zwhich decreases in diameter from the front end of the outer peripheral surface13t. The second protruding portion13chas a protruding surface13uextending forward, an annular surface13vextending inward in the radial direction from the front end of the protruding surface13u, and an inclined surface13wextending rearward from an end portion of the annular surface13vand obliquely extending inward in the radial direction.

FIG. 15Ais a partial sectional view illustrating the cover12, andFIG. 15Bis a longitudinal sectional view when the cover12is cut along a plane including the axis L. The cover12has a cylindrical shape, and is formed of an ABS resin, for example. The cover12may have a cylindrical shape. The outer surface of the cover12serves as a smooth surface having no irregularities. In some examples, the outer surface is an inclined surface12awhich gradually increases in diameter in a rearward direction. The rear end of the inclined surface12a(rear end of the cover12) has a bending portion12bwhich extends while being bent inward in the radial direction from the inclined surface12aand which is rounded.

The rear side of the inner surface12qof the cover12has an annular recess portion12nextending forward from the rear end12mof the cover12, and an annular irregular portion12plocated on the front side of the annular recess portion12n. The vicinity at the center of the inner surface12qof the cover12in the axial direction serves as a smooth surface12chaving no irregularities. An inclination angle of the inner surface12qwith respect to the axial direction is smaller than an inclination angle of the inclined surface12awith respect to the axial direction. Therefore, the portion of the cover12having the inclined surface12aand the inner surface12qgradually becomes thicker in the rearward direction.

The front side of the inner surface12qof the cover12has a wall portion12dprotruding inward in the radial direction from the smooth surface12c, and a female screw12edisposed in front of the wall portion12dand forms the other side of the screw portion30. The female screw12eis configured to include a spiral projection12fprotruding inward in the radial direction from the inner surface12qof the cover12. The cover12is mounted on the attachment member6by screwing the projection12fto the male screw6hforming the one side of the screw portion30.

FIG. 16is an enlarged view of the wall portion12dof the cover12. As illustrated inFIGS. 15A, 15B, and 16, a plurality of the wall portions12dare arranged side by side along the circumferential direction of the cover12. In some examples, the wall portions12dare intermittently formed along the circumferential direction of the cover12. The wall portion12dhas a top surface12gprotruding inward in the radial direction as the top surface12gis oriented rearward from the portion having the female screw12e, a bending portion12hfolded outward in the radial direction and forward from the rear end of the top surface12g, an inclined surface12jobliquely extending outward in the radial direction and forward from the bending portion12h, and a flat portion12kextending further outward in the radial direction from an end portion of the inclined surface12j.

In some examples, the plurality of wall portions12dare arranged at an equal interval in the circumferential direction, and the number of the wall portions12dis 12. The top surface12gof the wall portions12dextends along the axis L, and extends parallel to the axis L, for example. However, the top surface12gmay not extend parallel to the axis L. For example, the top surface12gmay be inclined in a direction away from the axis as the top surface12gis oriented rearward.

FIG. 17Ais a longitudinal sectional view when the accommodation portion10including the filling unit11, the cover12, and the wiper13are cut along a plane including the axis L.FIG. 17Bis an enlarged sectional view illustrating the wall portion12d, the first protruding portion13b, and one end11gof the filling unit11inFIG. 17A. In the wiper13, the extension portion13ais inserted into the opening11hof the filling unit11from the front side. The whole first side surface13eclosely adheres to the inner surface11aof the filling unit11, and the protruding surface13sof the first protruding portion13bcomes into contact with one end11g.

The filling unit11having the wiper13mounted thereon may be inserted into the cover12from the rear side. The wiper13and the filling unit11which are inserted into the cover12are engaged with the cover12in the axial direction in a state where the second protruding portion13cof the wiper13is in contact with the wall portion12dof the cover12in the axial direction. In some examples, the filling unit11and the wiper13engage with the cover12in the axial direction by fitting the annular projection portion11einto a recess portion of the annular irregular portion12pof the cover12. A position in the forward-rearward direction of the rear end11jof the filling unit11engaging with the cover12in the axial direction substantially coincides with a position in the forward-rearward direction of the rear end12mof the cover12(or located slightly forward of the rear end12m).

Then, in the wiper13mounted on the filling unit11, the annular surface13vand the inclined surface13wof the second protruding portion13centers the bending portion12hand the inclined surface12jof the wall portion12d. In this manner, the wiper13is pressed against the cover12in the axial direction, and closely adheres to the wall portion12d. The outer surface of the extension portion13a, which is the portion excluding the first protruding portion13bof the wiper13, closely adheres to the inner surface11aof the filling unit11in an airtight state. The wiper13mounted on the filling unit11in this way is pressed against the cover12in the axial direction. In this manner, the first protruding portion13bof the wiper13is interposed between each of the plurality of wall portions12dand one end11gon the opening11hside of the filling unit11in the axial direction. The first protruding portion13bclosely adheres to the inner surface12qof the cover12in an airtight state.

Referring toFIGS. 2 and 5, an example procedure for feeding the bar-shaped application material M of the application container1will be described. In the application container1, in an initial state illustrated inFIG. 2, the cap C is removed, and the leading cylinder3is exposed. Thereafter, the leading cylinder3and the coupling cylinder5are rotated relative to each other in one direction (for example, clockwise) which is a feeding direction of the bar-shaped application material M. If the leading cylinder3and the coupling cylinder5are rotated relative to each other in one direction, the moving body7synchronously rotated with respect to the leading cylinder3and the holding member8synchronously rotated with respect to the coupling cylinder5are rotated relative to each other in one direction.

As a result of this relative rotation, the leading cylinder3and the middle cylinder4are rotated relative to each other. Accordingly, the relative rotation may be achieved using rotational torques corresponding to rotational resistance applied between the leading cylinder3and the middle cylinder4. In addition, a screwing operation is performed in the screw portion20including the male screw7jof the moving body7and the spiral projection8dof the holding member8. The groove portion7cof the moving body7and the ridge3kof the inner surface of the leading cylinder3function as a detent for the moving body7against the leading cylinder3, and the holding member8is restricted in moving rearward to the coupling cylinder5. Accordingly, the moving body7slides forward to the leading cylinder3due to the above-described relative rotation. In this way, if the application material holder9moves forward toward the leading cylinder3together with the moving body7, the bar-shaped application material M appears from the opening3bof the leading end of the leading cylinder3, thereby bringing the bar-shaped application material M into a usable state.

An example operation associated with the application container1will now be described in detail. As illustrated inFIGS. 2, 17A and 17B, in the application container1, the cylindrical filling unit11having the opening11hin one end11gin the axial direction is accommodated in the cylindrical cover12, and has a double cylindrical shape. The female screw12eis formed on one end side of the inner surface12qof the cover12in the axial direction, and the male screw6his formed in the main body2(attachment member6) having the application tool P to be inserted into the filling unit11. In a state where the application tool P is inserted into the filling unit11, the male screw6hof the main body2is screwed into the female screw12eof the inner surface12qof the cover12. In this manner, the main body2is mounted on the cover12.

The wiper13formed of a soft material is fixed to the opening11hof the filling unit11and the inner surface12qof the cover12. The wiper13includes the first protruding portion13bprotruding outward in the radial direction. The inner surface12qof the cover12has the wall portions12d. The first protruding portion13bof the wiper13is interposed in the axial direction between the wall portions12dand an end portion (one end11g) on the opening11hside of the filling unit11. The first protruding portion13bis fixed in a state of being interposed between the wall portion12dof the inner surface12qof the cover12and one end11gon the opening11hside of the filling unit11.

Therefore, the first protruding portion13bof the wiper13is interposed in the axial direction between the wall portion12dof the inner surface12qof the cover12and one end11gof the filling unit11. Accordingly, a configuration can be adopted so that the force acting in the axial direction is less likely to be applied to the first protruding portion13bof the wiper13. That is, the wiper13may be protected from the force acting in the axial direction. As a result, the position of the wiper13may be prevented from being misaligned with the inner surface12qof the cover12and the filling unit11. Therefore, the wiper13can be prevented from being detached.

The wiper13has the second protruding portion13cprotruding (forward) in the axial direction from the face on the cover12side (wall portion12dside). The second protruding portion13centers the wall portion12din the axial direction. Therefore, the second protruding portion13cmay be prevented from slipping out of the wall portion12d. Accordingly, the wiper13may be prevented from being detached. Even if the force acting inward in the radial direction is applied to the second protruding portion13c, the wall portion12dinhibits the second protruding portion13cfrom moving inward in the radial direction. Accordingly, the second protruding portion13cmay be prevented from slipping inward in the radial direction from the wall portion12d. As a result, the wiper13may be reliably prevented from being detached. In some examples, the second protruding portion13cprotrudes in the axial direction as the second protruding portion13cis oriented outward in the radial direction. However, the shape of the second protruding portion is not limited to the shape of the second protruding portion13c. For example, the second protruding portion may protrude in a rectangular shape in the axial direction.

The plurality of wall portions12dmay be disposed along the circumferential direction on the inner surface12qof the cover12. In this manner, the wall portions12dare intermittently disposed along the circumferential direction on the inner surface12qof the cover12. Accordingly, the wall thickness of the cover12is relatively constant. Therefore, a so-called sink mark may be prevented from appearing when the cover12is manufactured by means of molding. The first protruding portion13bof the wiper13can be interposed between the plurality of wall portions12dand one end11gof the filling unit11. Therefore, even in a case where the plurality of wall portions12dare intermittently formed along the circumferential direction, the wiper13may be reliably prevented from being detached.

As illustrated inFIGS. 2 and 5, the application container1includes the bar-shaped application material M extending in the axial direction on the side opposite to the application tool P of the main body2. The main body2includes the feeding mechanism15for feeding the bar-shaped application material M in the axial direction. In this way, in the application container1, the filling unit11is internally filled with the liquid or powder application material A, and the application container1includes the bar-shaped application material M. Accordingly, one application container1can be provided with a plurality of application materials. The main body2includes the feeding mechanism15for feeding the bar-shaped application material M on the side opposite to the application tool P of the main body2. In this manner, the bar-shaped application material M can be fed to the side opposite to the application tool P.

The main body2includes the cylindrical attachment member6to which the application tool P is attached, and the stirring member S is disposed inside the attachment member6. The stirring member S collides with the inner surface of the attachment member6in accordance with vibrations of the main body2, thereby emitting collision sound. In this way, since the stirring member S emits the collision sound in accordance with the vibrations, a user of the application container1may be encouraged to vibrate the application container1. For example, the user may be encouraged to vibrate the application container1by utilizing a characteristic that the user wants to shake the application container1if the user hears the collision sound of the stirring member S. Therefore, the vibrations of the application container1can encourage the user to stir the application material A by using the stirring member S.

The wiper13is formed of the rubber material, and in some example the hardness of the wiper13is set to 40 to 80 in accordance with a type A durometer regulated in JIS 6253 (method of obtaining hardness of vulcanized rubber and thermoplastic rubber). Accordingly, the hardness of the wiper13is suitable for the attachment member6and the application tool P. Accordingly, the attachment member6and the application tool P can be pulled while a proper elastic force is applied from the wiper13to the attachment member6and the application tool P. Therefore, the attachment member6and the application tool P can be drawn using a proper force.

Second Group of Embodiments

Next, an application container according to a second group of embodiments will be described with reference toFIGS. 18A, 18B, 19A, and19B. In the second group of embodiments, a configuration of a cover22is different from the cover12according to the first group of embodiments. Hereinafter, in order to avoid repeated description, elements repeated from the first group of embodiments will be appropriately omitted in description.

The front side of the inner surface12qof the cover22has a wall portion22dprotruding inward in the radial direction. For example, one wall portion22dis disposed therein, and is formed on the entire periphery along the circumferential direction of the cover22. In some examples, the expression “wall portion formed on the entire periphery along the circumferential direction” may be understood to include both a wall portion extending throughout the entire circumferential direction and a wall portion extending throughout the entire circumferential direction and having an intermittent portion in the circumferential direction. That is, the “wall portion formed on the entire periphery along the circumferential direction” may include a wall portion having a portion which does not protrude in the circumferential direction on the inner surface of the cover.

The wall portion22dhas an inner surface22gextending in a direction away from an outer surface22aof the cover22as the inner surface22gis oriented rearward (inner side of the outer surface22ain the radial direction and in a direction in which the cover22becomes thicker). Additionally, the wall portion22dmay include a bending portion22hfolded outward in the radial direction and forward from the rear end of the inner surface22g, an inclined surface22jobliquely extending outward in the radial direction and forward from the bending portion22h, and a flat portion22kextending further outward in the radial direction from an end portion outside in the radial direction of the inclined surface22j. The inner surface22gextends along the axis L, and extends parallel to the axis L, for example. However, the inner surface22gmay not extend parallel to the axis L. For example, the inner surface22gmay be inclined in a direction away from the axis L as the inner surface22gis oriented rearward. Similar to the first group of embodiments, the wiper13mounted on the filling unit11is pressed against the cover22in the axial direction (forward), the first protruding portion13bof the wiper13is interposed in the axial direction between the wall portion22dand one end11gof the filling unit11.

In the application container according to the second group of embodiments, the first protruding portion13bis fixed in a state of being interposed in the axial direction between the wall portion22dof the inner surface12qof the cover22and one end11gon the opening11hside of the filling unit11. Therefore, a configuration can be adopted so that the force acting in the axial direction is less likely to be applied to the first protruding portion13bof the wiper13. Accordingly, the position of the wiper13may be prevented from being misaligned with the inner surface12qof the cover22and the filling unit11. As a result, the wiper13may be prevented from being detached, similar to other examples described herein.

According to the second group of embodiments, the wall portion22dextends throughout the circumferential direction of the cover22on the inner surface12qof the cover22. Accordingly, a large contact area of the wall portion22din contact with the wiper13(second protruding portion13c) can be secured. Therefore, the wiper13may be reliably prevented from being detached, and the wiper13may be further made airtight.

Third Group of Embodiments

Subsequently, an application container according to a third group of embodiments will be described with reference toFIGS. 20A, 20B, 21A, and21B. In the third group of embodiments, each configuration of a cover32and a wiper33is different from that according to the second group of embodiments. Hereinafter, elements repeated from the respective embodiments will be appropriately omitted in description.

Similar to the cover22, the cover32includes a wall portion32d, and the wall portion32dis formed on the entire periphery of the cover32in the circumferential direction. The wall portion32dincludes an inner surface32gextending in a direction away from an outer surface32aof the cover32as the inner surface32gis oriented rearward, a bending portion32hbent outward in the radial direction from the rear end of the inner surface32g, and a flat surface32kextending outward in the radial direction from the bending portion32h. For example, an angle of the flat surface32kwith respect to the axial direction is 90°. Similar to the inner surface22g, the inner surface32gextends along the axis L. For example, the inner surface32gmay extend parallel to the axis L. Alternatively, the inner surface32gmay be inclined in a direction away from the axis L as the inner surface32gis oriented rearward.

The wiper33is different from the wiper13in that the wiper33does not have a portion corresponding to the second protruding portion13c. The wiper33has a first protruding portion33bwhich protrudes outward in the radial direction in the front end of the extension portion13a. The first protruding portion33bhas a protruding surface33sextending outward in the radial direction from the front end of the extension portion13a, an outer peripheral surface33eextending forward from an end portion and outside in the radial direction of the protruding surface33s, and an annular surface33vextending inward in the radial direction from the front end of the outer peripheral surface33e. For example, the angle of the annular surface33vwith respect to the outer peripheral surface33eis the same as the angle of the flat surface32kwith respect to the axial direction, and is set to 90°.

In some examples, the wiper33is mounted on the filling unit11, and the wiper33mounted on the filling unit11is pressed against the cover32in the axial direction. The first protruding portion33bof the wiper33is interposed in the axial direction between the wall portion32dand one end11gof the filling unit11. In some examples, the outer peripheral surface33eof the first protruding portion33bclosely adheres to the inner surface12qof the cover32, one end11gcomes into contact with the protruding surface33s, and the flat surface32kof the wall portion32dcomes into contact with the annular surface33v.

In the application container according to the third group of embodiments, the first protruding portion33bis fixed in a state of being interposed in the axial direction between the wall portion32dof the cover32and one end11gof the filling unit11. Accordingly, a configuration can be adopted so that the force acting in the axial direction is less likely to be applied to the first protruding portion33b. Therefore, the position of the wiper33may be prevented from being misaligned with the cover32and the filling unit11. Accordingly, the wiper33may be prevented from being detached.

Hitherto, respective example embodiments of the application container have been described. However, the example embodiments may be modified within the scope of the present disclosure. For example, in the above-described first to third groups of embodiments, the cover and the wiper which are provided with various shapes have been described. However, each shape of the cover and the wiper can be further changed. In addition, changes in a size, a material, and an arrangement aspect of the cover and the wiper may be appropriately made, and changes in a shape, a size, a material, and an arrangement aspect of the filling unit may also be appropriately made.

The bar-shaped application material M has been described which includes the inclined portion M1, the pair of flat surface M2, and the side surface M3extending in the axial direction as illustrated inFIG. 5. However, the shape, the size, the material, and the arrangement aspect of the bar-shaped application material can be appropriately changed. Furthermore, in some of the above-described examples, the main body2has been described which includes the leading cylinder3, the middle cylinder4, the coupling cylinder5, the attachment member6, the moving body7, the holding member8, and the application material holder9. However, the configuration of the components forming the main body can be appropriately changed. In addition, the shape, the size, the material, and the arrangements aspect of the leading cylinder, the middle cylinder, the coupling cylinder, the attachment member, the moving body, the holding member, and the application material holder can also be appropriately changed.
