Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the above-described cosmetic storage container, there is a concern that the user of the cosmetic storage container may accidentally push up the operating pin, causing the cosmetic tools to be exposed. When the cosmetic tools are exposed, there is a concern that objects located around the cosmetic storage container may be soiled.

[0006] An object of the present disclosure is to provide a dispensing container that can suppress the exposure of cosmetics against the user's intention.

Means for Solving the Problem

[0007] The dispensing container according to the present disclosure includes: (1) a container having a cylindrical accommodating portion for accommodating cosmetics, with a first opening formed where the cosmetics are exposed; a lid portion for opening and closing the first opening; and a locking member for locking the lid portion in a state where the lid portion closes the first opening. The lid portion opens and closes the first opening while being connected to at least one of the locking member and the container. When the locking member moves in the axial direction, which is the direction in which the axis of the accommodating portion extends with respect to the container, the locking of the lid portion by the locking member is released, and the cosmetics can be exposed from the first opening.

[0008] In this dispensing container, the container has an accommodating portion for accommodating cosmetics and a first opening where the cosmetics are exposed, and the first opening is opened and closed by the lid portion. The dispensing container is provided with a locking member, and the locking member locks the lid portion in a state where the lid portion closes the first opening. By the locking member locking the lid portion, the state where the lid portion closes the first opening is maintained, so that it is possible to prevent the first opening from opening unintentionally by the user of the dispensing container. When the locking member moves in the axial direction with respect to the container, the locking of the lid portion is released, and at this time, the cosmetics can be exposed from the first opening. Therefore, it is possible to prevent the locking of the lid portion from being released unless the user moves the locking member in the axial direction, and at this time, it is possible to regulate the exposure of the cosmetics from the first opening. As a result, it is possible to suppress the unintentional exposure of the cosmetics from the first opening, and thus it is possible to suppress the soiling of objects located around the dispensing container.

[0009] (2) In the above (1), the locking member may have a cylindrical shape into which the container is inserted. The container may have an operating portion that is operated when the container rotates relative to the locking member to dispense the cosmetic. In a state where the locking member locks the lid portion, the operating portion may be non-rotatable relative to the locking member. When the locking of the lid portion by the locking member is released, the operating portion may be rotatable relative to the locking member. In this case, in addition to the fact that the cosmetic is difficult to be exposed due to the lid portion being locked by the locking member, since the operating portion is non-rotatable relative to the locking member, it is possible to suppress the unintentional dispensing of the cosmetic. Therefore, it is possible to further suppress the exposure of the cosmetic against the intention of the user.

[0010] (3) In the above (1) or (2), the lid portion may be rotatable via a hinge portion provided on the container, and the first opening may be opened and closed by rotating via the hinge portion. The locking member may have a second opening through which the cosmetic dispensed from the first opening appears, and a locking portion that abuts against the lid portion to lock the lid portion. In this case, the lid portion is rotatable via the hinge portion. The locking member has a locking portion that abuts against the lid portion to lock the lid portion. Thus, when the lid portion rotates and the locking portion abuts against the lid portion along the direction of closing the first opening, the lid portion can be easily locked. As a result, it is possible to suppress the exposure of the cosmetic against the intention of the user. Also, in a state where the lid portion rotates and the first opening is opened, the cosmetic passing through the first opening can be exposed via the second opening. Therefore, the cosmetic can be exposed without removing the locking member.

Advantages of the Invention

[0011] According to the present disclosure, it is possible to suppress the exposure of the cosmetic against the intention of the user.

Embodiments for Carrying out the Invention

[0013] Hereinafter, embodiments of the dispensing container according to the present disclosure will be described with reference to the drawings. In the description of the drawings, the same or corresponding elements are denoted by the same reference numerals, and redundant descriptions are omitted as appropriate. The drawings may be drawn with some parts simplified or exaggerated for ease of understanding, and dimensional ratios and the like are not limited to those shown in the drawings.

[0014] FIG. 1 is a perspective view of the dispensing container 1. FIG. 2 is an exploded perspective view of the dispensing container 1. The dispensing container 1 is a container capable of dispensing the cosmetic M (see FIG. 3) and retracting the cosmetic M. For example, a part of the components constituting the dispensing container 1 has a cylindrical shape. Hereinafter, the direction in which the axis of the said part of the dispensing container 1 extends may be referred to as the axial direction D1, and the direction along the ring centered on the axis of the dispensing container 1 may be referred to as the circumferential direction D2. Hereinafter, the state in which the cosmetic M is dispensed from the dispensing container 1 may be referred to as the "used state", and the state in which the cosmetic M is not exposed from the dispensing container 1 and the cosmetic M is accommodated in the dispensing container 1 may be referred to as the "accommodated state".

[0015] The dispensing container 1 has an operation part 21 and a lock member 7 which are parts touched by the user of the dispensing container 1. The operation part 21 and the lock member 7 are arranged side by side along the axial direction D1. In the following description, the direction from the operation part 21 toward the lock member 7 in the axial direction D1 may be referred to as "front", "front side" or "forward", and the direction from the lock member 7 toward the operation part 21 in the axial direction D1 may be referred to as "rear", "rear side" or "backward".

[0016] The dispensing container 1 includes a container 2 that houses the cosmetic M, a support member 3 that is housed in the container 2 and supports the cosmetic M, a pressing member 4 that is housed in the container 2, a screw cylinder 5 to which the support member 3 and the pressing member 4 are assembled, an inner cap 6 that is connected to the screw cylinder 5, a lock member 7 that is located on the front side of the container 2, and a restricting portion 8 into which the screw cylinder 5 is inserted. As shown in FIG. 1, in the housed state, the container 2, the inner cap 6, and the lock member 7 are exposed. More specifically, the operation portion 21 of the container 2, the lid portion 61 of the inner cap 6, and the lock member 7 are exposed. The lock member 7 has a second opening 7a. The second opening 7a is located, for example, at the front end of the lock member 7.

[0017] Next, a method of using the dispensing container 1 will be described with reference to FIGS. 3(a), 3(b), and 3(c). FIG. 3(a) is a perspective view of the dispensing container 1 in the housed state. FIG. 3(b) is a perspective view of the dispensing container 1 in a state where the lock member 7 has moved forward with respect to the container 2 (operation portion 21). FIG. 3(c) is a perspective view of the dispensing container 1 in the use state. As shown in FIG. 3(a), in the housed state, the operation portion 21 of the container 2 and the lock member 7 are close to each other. For example, the operation portion 21 of the container 2 and the lock member 7 are in contact with each other.

[0018] With the lid portion 61 closing a first opening 221a (see FIG. 4) described later, the lock member 7 locks the lid portion 61. Hereinafter, a state where the operation portion 21 of the container 2 and the lock member 7 are close to each other may be referred to as a "locked state". In the locked state, the operation portion 21 is non-rotatable relative to the lock member 7 in the circumferential direction D2. In the present embodiment, "synchronous rotation" means that a plurality of components rotate integrally, and "relative rotation" means that one component rotates relative to the other component. In the locked state, the opening of the lid portion 61 is restricted, and the lid portion 61 is exposed from the second opening 7a. In the locked state, the lock member 7 is in contact with the lid portion 61, and the lid portion 61 cannot be opened.

[0019] The locking member 7 is movable in the axial direction D1 with respect to the operation portion 21. Hereinafter, as shown in FIG. 3(b), the state in which the locking member 7 has moved forward with respect to the operation portion 21 of the container 2 may be referred to as the "unlocked state". In the unlocked state, the operation portion 21 is relatively rotatable in the circumferential direction D2 with respect to the locking member 7. By relatively rotating the operation portion 21 with respect to the locking member 7 in one direction D2a in the circumferential direction D2, the cosmetic M is dispensed. The one direction D2a refers to the direction in which the operation portion 21 rotates clockwise with respect to the locking member 7, for example, when viewed from the operation portion 21 along the axial direction D1 toward the locking member 7. The second opening 7a exposes the cosmetic M dispensed from the first opening 221a (see FIG. 4) described later. The second opening 7a causes the cosmetic M dispensed from the first opening 221a to appear. In the unlocked state, a space is formed between the inner surface of the front end of the locking member 7 and the lid portion 61, making it possible to open the lid portion 61.

[0020] As shown in FIG. 3(c), by relatively rotating the operation portion 21 with respect to the locking member 7 in the one direction D2a, the cosmetic M protrudes with respect to the locking member 7. Next, a method of returning from the use state to the storage state and a method of returning from the unlocked state to the locked state will be described. In the use state, by relatively rotating the operation portion 21 with respect to the locking member 7 in the opposite direction D2b, the cosmetic M is retracted. The opposite direction D2b refers to the direction opposite to the one direction D2a. The retracted cosmetic M immerses in the second opening 7a. When the cosmetic M immerses in the second opening 7a, the dispensing container 1 returns from the use state to the storage state. Next, by moving the locking member 7 in the axial direction D1 (rearward) so as to bring the locking member 7 closer to the operation portion 21, the dispensing container 1 returns from the unlocked state to the locked state.

[0021] Next, each component of the dispensing container 1 and the internal structure of the dispensing container 1 will be described. FIG. 4 is a cross-sectional view taken along line IV-IV of FIG. 1, showing the dispensing container 1 in the housed state and in the locked state. For example, the container 2 has an operation part 21 that is operated when rotating relative to the lock member 7 to dispense the cosmetic M, and a housing cylinder 22 inserted into the operation part 21. Inside the housing cylinder 22, a support member 3 and a pressing member 4 are housed. For example, in the housed state, the support member 3 is located behind the pressing member 4. For example, an inner cap 6 is arranged inside the lock member 7, and a screw cylinder 5 is arranged inside the inner cap 6.

[0022] For example, the operation part 21 is separate from the housing cylinder 22. However, the operation part 21 may be integrated with the housing cylinder 22. For example, the operation part 21 has a cylindrical shape, and the housing cylinder 22 is housed inside the operation part 21. An insertion space for inserting the screw cylinder 5 is formed between the operation part 21 and the housing cylinder 22. For example, the rear part of the screw cylinder 5 is inserted into this insertion space. The housing cylinder 22 is housed inside the screw cylinder 5.

[0023] The operation part 21 surrounds a part of the housing cylinder 22 (for example, the rear part of the housing cylinder 22). FIG. 5 is a perspective view of the operation part 21. FIG. 6 is a front view of the operation part 21. As shown in FIGS. 4, 5, and 6, the operation part 21 has a main part 211 that is the part that the user pinches when operating the operation part 21, and a neck part 212 that extends forward from the main part 211. The main part 211 extends along the axial direction D1. The main part 211 has a non-circular shape (for example, a rectangular shape) when viewed in the axial direction D1. For example, the shape of the main part 211 when viewed along the axial direction D1 presents a polygonal shape with rounded corners (as an example, a square shape with rounded corners). In this case, it is possible to suppress the slipping of the finger with respect to the main part 211 and make it easier to pinch the main part 211 with the finger.

[0024] The length of the head portion 212 in the axial direction D1 is shorter than the length of the main portion 211 in the axial direction D1. The rear end of the head portion 212 exhibits a non-circular shape (e.g., rectangular shape) when viewed from the axial direction D1. The front end of the head portion 212 exhibits a rectangular shape with a larger corner rounding than the rear end of the head portion 212 when viewed from the axial direction D1, and exhibits a shape approximating a circular shape, but may exhibit a circular shape, thereby enabling a smooth transition from the unlocked state to the locked state. The head portion 212 has an outer peripheral surface extending from the rear end of the head portion 212 toward the front end of the head portion 212. When viewed from the axial direction D1, the area of the portion surrounded by the outer peripheral surface of the head portion 212 is smaller than the area of the portion surrounded by the outer peripheral surface of the main portion 211. The operation portion 21 has a step portion 21a that protrudes radially outward from the rear end of the outer peripheral surface of the head portion 212 between the front end of the outer peripheral surface of the main portion 211 and the rear end of the outer peripheral surface of the head portion 212.

[0025] The operation portion 21 has a front inner peripheral surface 21b, a rear inner peripheral surface 21c, and a fitting portion 21d that respectively define through holes penetrating the operation portion 21 along the axial direction D1. The front inner peripheral surface 21b extends rearward from the front end of the operation portion 21. The fitting portion 21d is provided at the rear end of the operation portion 21. The rear inner peripheral surface 21c is disposed between the front inner peripheral surface 21b and the fitting portion 21d. For example, the front inner peripheral surface 21b exhibits a circular shape when viewed from the axial direction D1. For example, the rear inner peripheral surface 21c and the fitting portion 21d exhibit a rectangular shape when viewed from the axial direction D1. The inner diameter of the front inner peripheral surface 21b is smaller than the length of the rear inner peripheral surface 21c intersecting the axial direction D1. The operation portion 21 has an inner peripheral surface convex portion 21g on the front inner peripheral surface 21b. For example, the inner peripheral surface convex portion 21g is a convex portion that protrudes radially inward and extends along the circumferential direction D2 on the front inner peripheral surface 21b. The operation portion 21 has a plurality (e.g., four) of inner peripheral surface convex portions 21g. The plurality of inner peripheral surface convex portions 21g are arranged along the circumferential direction D2 and are arranged at intervals from each other. The inner peripheral surface convex portion 21g is located at the rear end of the front inner peripheral surface 21b.

[0026] The fitting portion 21d has a recess 21e located at the front end of the fitting portion 21d and an opening 21f located at the rear end of the fitting portion 21d. The recess 21e is, for example, a recess that depresses outward in the radial direction of the neck portion 212. The fitting portion 21d has four recesses 21e. When viewed from the axial direction D1, one recess 21e is provided on each side of the rectangle formed by the inner contour of the fitting portion 21d. The opening 21f constitutes a step protruding outward in the radial direction.

[0027] FIG. 7 is a perspective view of the housing cylinder 22. FIG. 8 is a front view of the housing cylinder 22. As shown in FIGS. 4, 7, and 8, the housing cylinder 22 has a housing portion 221 for housing the cosmetic M, an insertion portion 222 which is a portion inserted into the operation portion 21, and a fitting portion 223 extending rearward from the rear end of the insertion portion 222. Further, the housing cylinder 22 has a housing cylinder convex portion 224 provided at the boundary between the housing portion 221 and the insertion portion 222, and a rear end portion 225 for closing the rear end of the housing cylinder 22. The housing portion 221 has a cylindrical shape. The housing portion 221 has, for example, a cylindrical shape. The axis of the housing portion 221 extends along the axial direction D1. The outer diameter of the housing portion 221 is smaller than the inner diameter of the front inner peripheral surface 21b of the operation portion 21.

[0028] The housing portion 221 has a first opening 221a through which the cosmetic M is exposed. The first opening 221a is located at the front end of the housing portion 221. The housing portion 221 has a first guide hole 221b and a second guide hole 221c formed at a position different from the first guide hole 221b. The first guide hole 221b and the second guide hole 221c penetrate the housing portion 221. Each of the first guide hole 221b and the second guide hole 221c extends along the axial direction D1.

[0029] The first guide hole 221b extends rearward from the front end of the housing portion 221. An opening of the first guide hole 221b may be formed at the front end of the housing portion 221. For example, the first guide hole 221b is a notch formed in the housing portion 221. The housing portion 221 has a pair of first guide holes 221b. The pair of first guide holes 221b are arranged at positions sandwiching the axis of the housing cylinder 22.

[0030] The second guide hole 221c is located closer to the rear end of the accommodating portion 221 than the first guide hole 221b. For example, the distance from the second guide hole 221c to the rear end of the accommodating portion 221 is shorter than the distance from the second guide hole 221c to the front end of the accommodating portion 221. The front end of the second guide hole 221c is located in front of the rear end of the first guide hole 221b. The length of the second guide hole 221c in the axial direction D1 is longer than the length of the first guide hole 221b in the axial direction D1. The accommodating portion 221 has a pair of second guide holes 221c. The pair of second guide holes 221c are arranged at positions sandwiching the axis of the accommodating cylinder 22.

[0031] The insertion portion 222 extends rearward from the rear end of the accommodating portion 221. The insertion portion 222 has, for example, a cylindrical shape. The outer diameter of the insertion portion 222 is equal to or less than the inner diameter of the rear inner peripheral surface 21c of the operation portion 21.

[0032] The fitting portion 223 is fitted to the fitting portion 21d of the operation portion 21. The fitting portion 223 has a rectangular shape surrounding the insertion portion 222 when viewed in the axial direction D1. The fitting portion 223 has a thickness along the axial direction D1. The fitting portion 223 has a step portion 223a located on the rear end side of the fitting portion 223, a convex portion 223b located on the front end side of the fitting portion 223, and a concave portion 223c constituting the side surface of the fitting portion 223. The concave portion 223c is a recessed portion compared with the step portion 223a and the convex portion 223b. The step portion 223a surrounds the concave portion 223c when viewed in the axial direction D1. The step portion 223a is fitted into the opening portion 21f. The convex portion 223b is provided so as to protrude radially outward from the concave portion 223c. Each convex portion 223b enters each concave portion 21e.

[0033] The accommodating cylinder convex portion 224 extends in the circumferential direction D2 at the boundary between the accommodating portion 221 and the insertion portion 222. The accommodating cylinder convex portion 224 is arranged to abut against the rear end of the screw cylinder 5, suppressing the rearward movement of the screw cylinder 5. For example, the accommodating cylinder convex portion 224 has an annular shape when viewed in the axial direction D1. The rear end portion 225 has, for example, a rectangular shape. For example, the length (thickness) of the rear end portion 225 in the axial direction D1 is slightly shorter than the length of the fitting portion 223 in the axial direction D1.

[0034] The housing cylinder 22 has a groove 22a provided at the rear end of the housing portion 221. The groove 22a extends, for example, in the circumferential direction D2. As an example, the groove 22a extends over the entire circumference of the housing cylinder 22. The outer diameter of the housing cylinder 22 in the groove 22a is smaller than the outer diameter of the housing portion 221 and the outer diameter of the insertion portion 222. An O-ring R is disposed in the groove 22a. The O-ring R is constituted by an elastic member. The O-ring R surrounds the housing cylinder 22 so as to fill the groove 22a. The O-ring R imparts an appropriate rotational resistance to the relative rotation between the housing cylinder 22 and the screw cylinder 5, and the user can feel a good touch and a sense of luxury associated with the rotation operation.

[0035] For example, the housing cylinder 22 may have a front inner peripheral surface 22b extending rearward from the front end of the housing cylinder 22 and a rear inner peripheral surface 22c extending from the front inner peripheral surface 22b to the rear end portion 225. In that case, the inner diameter of the front inner peripheral surface 22b may be larger than the inner diameter of the rear inner peripheral surface 22c. The housing cylinder 22 may have a stepped portion 22d protruding radially inward of the housing cylinder 22 from the rear end of the front inner peripheral surface 22b between the rear end of the front inner peripheral surface 22b and the front end of the rear inner peripheral surface 22c. The stepped portion 22d may extend along the circumferential direction D2.

[0036] A configuration for connecting the housing cylinder 22 to the operation portion 21 will be described. The insertion portion 222 of the housing cylinder 22 is inserted into the internal space of the operation portion 21 formed by the rear inner peripheral surface 21c. The fitting portion 223 of the housing cylinder 22 is fitted to the fitting portion 21d of the operation portion 21. More specifically, the convex portion 223b of the fitting portion 223 enters the concave portion 21e of the operation portion 21, whereby the fitting portion 223 is fitted to the fitting portion 21d. Thereby, the housing cylinder 22 is engaged with the operation portion 21 in the axial direction D1. When the fitting portion 223 of the housing cylinder 22 enters the fitting portion 21d, the fitting portion 223 and the fitting portion 21d exhibit a non-circular shape when viewed from the axial direction D1. Therefore, the housing cylinder 22 is engaged with the operation portion 21 in the circumferential direction D2 and is capable of synchronous rotation with the operation portion 21.

[0037] Next, the support member 3 will be described. FIG. 9 is a perspective view of the support member 3. FIG. 10 is a cross-sectional view taken along the line X-X of FIG. 9. As shown in FIGS. 4, 9, and 10, the support member 3 is accommodated inside the accommodation cylinder 22. The support member 3 supports the cosmetic M. The support member 3 has a main body portion 31 having a cylindrical shape (e.g., a cylindrical shape as an example) and a second protrusion 32 provided on the outer peripheral surface of the main body portion 31. The cosmetic M is accommodated inside the main body portion 31. More specifically, in a state where the cosmetic M protrudes from the opening at the front end of the main body portion 31, the rear portion of the cosmetic M is accommodated in the main body portion 31.

[0038] The second protrusion 32 enters the second guide hole 221c (see FIG. 7) of the accommodation cylinder 22. The second protrusion 32 has a columnar shape (e.g., a columnar shape as an example). The second protrusion 32 protrudes radially outward from the outer peripheral surface of the main body portion 31, for example. The support member 3 has, for example, a pair of second protrusions 32. The pair of second protrusions 32 are arranged at positions sandwiching the axis of the main body portion 31. By the second protrusion 32 moving along the second guide hole 221c, the support member 3 is made movable in the axial direction D1 inside the accommodation cylinder 22. The support member 3 is engaged with the container 2 (accommodation portion 221) in the circumferential direction D2 because the second protrusion 32 enters the second guide hole 221c. The support member 3 is made rotatable in synchronization with the accommodation cylinder 22 of the container 2.

[0039] The support member 3 has an accommodation portion 3a inside which the cosmetic M is accommodated. The accommodation portion 3a is, for example, a part of the inner peripheral surface of the support member 3. The accommodation portion 3a has, for example, a circular shape when viewed in the axial direction D1. For example, the length of the accommodation portion 3a in the axial direction D1 is shorter than half of the length of the support member 3 in the axial direction D1. The support member 3 has a bottom portion 3b provided at the rear end of the accommodation portion 3a. The cosmetic M accommodated in the accommodation portion 3a is in contact with the bottom portion 3b, for example. The support member 3 has a claw portion 33 provided on the accommodation portion 3a. The claw portion 33 bites into the cosmetic M accommodated in the accommodation portion 3a. By the claw portion 33 biting into the cosmetic M, the support member 3 can firmly support the cosmetic M. The claw portion 33 extends along the axial direction D1, for example. The claw portion 33 protrudes radially inward of the main body portion 31 in the accommodation portion 3a.

[0040] The support member 3 has an opening 3c provided in the bottom portion 3b. The opening 3c penetrates the bottom portion 3b in the axial direction D1. For example, the center of the opening 3c overlaps with the axis of the support member 3. When the cosmetic M is accommodated in the accommodating portion 3a, the air existing between the cosmetic M and the bottom portion 3b escapes from the opening 3c, making it easier to push the cosmetic M into the bottom portion 3b.

[0041] For example, the support member 3 may have a rib 34 extending from the bottom portion 3b to the rear end of the main body portion 31. The rib 34 extends, for example, from the inner peripheral surface of the bottom portion 3b to the outer peripheral surface of the bottom portion 3b when viewed from the axial direction D1. The support member 3 may have a pair of ribs 34. The pair of ribs 34 may be arranged at positions sandwiching the axis of the main body portion 31.

[0042] FIG. 11 is a perspective view of the pressing member 4. As shown in FIGS. 4 and 11, the pressing member 4 is accommodated inside the accommodating portion 221 of the accommodating cylinder 22. The pressing member 4 is located on the front side of the accommodating cylinder 22. The pressing member 4 has a cylindrical shape into which the cosmetic M enters. More specifically, the pressing member 4 has a main body portion 41 presenting a cylindrical shape (as an example, a cylindrical shape) and a first protrusion 42 provided on the outer peripheral surface of the main body portion 41. Both ends of the main body portion 41 in the axial direction D1 are open. The inner diameter of the main body portion 41 is larger than the outer diameter of the cosmetic M. The cosmetic M can enter the main body portion 41. The opening surface of the opening at the front end of the main body portion 41 may be inclined with respect to a plane orthogonal to the axial direction D1. The opening surface of the opening at the rear end of the main body portion 41 extends along a plane orthogonal to the axial direction D1.

[0043] The first protrusion 42 enters the first guide hole 221b (see FIG. 7) of the housing cylinder 22. The first protrusion 42 has a columnar shape (for example, a cylindrical shape). The first protrusion 42 protrudes radially outward from the outer peripheral surface of the main body portion 41, for example. The pressing member 4 has, for example, a pair of first protrusions 42. The pair of first protrusions 42 are arranged at positions sandwiching the axis of the main body portion 41. By the first protrusion 42 moving along the first guide hole 221b, the pressing member 4 is made movable in the axial direction D1 inside the housing cylinder 22. The pressing member 4 is engaged with the container 2 (the housing portion 221) in the circumferential direction D2 because the first protrusion 42 enters the first guide hole 221b. The pressing member 4 is made rotatable in synchronization with the housing cylinder 22 of the container 2.

[0044] FIG. 12 is a perspective view of the screw cylinder 5. FIG. 13 is a sectional view taken along line XIII-XIII of FIG. 12. As shown in FIGS. 4, 12, and 13, the screw cylinder 5 houses the housing portion 221 of the housing cylinder 22. The housing portion 221 is inserted into the screw cylinder 5. The screw cylinder 5 has, for example, a cylindrical shape. The screw cylinder 5 has a front insertion portion 51 that is inserted into the inner cap 6, a rear insertion portion 52 that is inserted into the operation portion 21, and an intermediate portion 53 that is located between the front insertion portion 51 and the rear insertion portion 52. The front insertion portion 51, the rear insertion portion 52, and the intermediate portion 53 have, for example, a cylindrical shape.

[0045] The screw cylinder 5 has an annular convex portion 54 that extends along the circumferential direction D2 and a convex portion 55 that extends along the axial direction D1. The annular convex portion 54 is located at the boundary between the front insertion portion 51 and the intermediate portion 53. The annular convex portion 54 and the convex portion 55 protrude radially outward of the screw cylinder 5 on the outer peripheral surface of the screw cylinder 5. The convex portion 55 intersects the annular convex portion 54. For example, the convex portion 55 crosses the annular convex portion 54 in the axial direction D1. The convex portion 55 is provided so as to straddle the front insertion portion 51 and the intermediate portion 53.

[0046] The screw cylinder 5 has convex portions 56 and 57 provided on the outer peripheral surface of the intermediate portion 53. The convex portion 57 is provided near the front end of the rear insertion portion 52. The convex portion 56 is arranged along the axial direction D1 with the convex portion 57. The convex portion 56 is located behind the convex portion 57. The convex portions 56 and 57 protrude from the outer peripheral surface of the rear insertion portion 52. For example, the convex portions 56 and 57 are oval-shaped when viewed from the outside in the radial direction of the screw cylinder 5. For example, the respective protruding amounts of the convex portions 56 and 57 with respect to the outer peripheral surface of the rear insertion portion 52 increase as they approach the center of the convex portions 56 and 57 respectively. The convex portion 56 has the same shape as the convex portion 57. The screw cylinder 5 has three convex portions 56 arranged along the circumferential direction D2 and three convex portions 57.

[0047] The screw cylinder 5 has a flange portion 58 located between the rear insertion portion 52 and the intermediate portion 53. The flange portion 58 is, for example, an annular convex portion extending along the circumferential direction D2. The outer diameter of the flange portion 58 is larger than the outer diameter of the intermediate portion 53 and the outer diameter of the rear insertion portion 52. The amount of protrusion of the flange portion 58 radially outward with respect to the rear insertion portion 52 and the intermediate portion 53 is larger than the amount of protrusion of the convex portion 57 from the outer peripheral surface of the rear insertion portion 52. The outer diameter of the flange portion 58 is larger than the inner diameter of the inner peripheral surface convex portion 21g. By the flange portion 58 coming into contact with the inner peripheral surface convex portion 21g along the axial direction D1, the screw cylinder 5 is restricted from moving forward with respect to the operation portion 21.

[0048] The screw cylinder 5 has an enlarged diameter portion 59 located at the rear end of the rear insertion portion 52. The enlarged diameter portion 59 is cylindrical. The inner diameter of the enlarged diameter portion 59 is, for example, larger than the inner diameter of the rear insertion portion 52. The outer diameter of the enlarged diameter portion 59 is smaller than the inner diameter of the rear inner peripheral surface 21c. An O-ring R is in contact with the inner peripheral surface of the enlarged diameter portion 59. By the enlarged diameter portion 59 coming into contact with the housing cylinder convex portion 224, the screw cylinder 5 is restricted from moving backward with respect to the housing cylinder 22. The screw cylinder 5 is engaged with the container 2 in the axial direction D1 by the contact between the flange portion 58 and the inner peripheral surface convex portion 21g and the contact between the enlarged diameter portion 59 and the housing cylinder convex portion 224.

[0049] The screw cylinder 5 has grooves on its peripheral wall. The grooves provided on the peripheral wall of the screw cylinder 5 include a first groove 5a into which the first protrusion 42 (see FIG. 11) of the pressing member 4 fits, and a second groove 5b into which the second protrusion 32 (see FIG. 9) of the support member 3 fits. The first groove 5a is provided in the front insertion portion 51. The first groove 5a penetrates the front insertion portion 51. The first groove 5a includes a first inclined groove 5c extending in a first inclined direction D3 which is a direction inclined with respect to the axial direction D1, and a second inclined groove 5d extending in a second inclined direction D4 which is a direction inclined in both the axial direction D1 and the first inclined direction D3 from the end of the first inclined groove 5c. In the present embodiment, the second inclined groove 5d extends along the circumferential direction D2. That is, the second inclined direction D4 is the same direction as the circumferential direction D2. One end of the second inclined groove 5d is connected to the front end of the first inclined groove 5c. The screw cylinder 5 has, for example, a pair of first grooves 5a. The pair of first grooves 5a are arranged at positions sandwiching the axis of the screw cylinder 5. One of the pair of first grooves 5a overlaps with the other of the pair of first grooves 5a when the screw cylinder 5 rotates 180° around the axis.

[0050] The second groove 5b is provided on the inner peripheral surface of the screw cylinder 5. The second groove 5b is, for example, in a spiral shape extending around the axis of the screw cylinder 5. In this case, the second groove 5b is a spiral groove. For example, the second groove 5b does not penetrate the screw cylinder 5. The screw cylinder 5 has a pair of second grooves 5b. The pair of second grooves 5b are arranged at positions sandwiching the axis of the screw cylinder 5. One of the pair of second grooves 5b overlaps with the other of the pair of second grooves 5b when the screw cylinder 5 rotates 180° around the axis. The second groove 5b includes a third inclined groove 5e extending in a third inclined direction D5 which is a direction inclined in the axial direction D1, the first inclined direction D3, and the second inclined direction D4. The angle of the third inclined direction D5 with respect to the axial direction D1 is larger than the angle of the first inclined direction D3 with respect to the axial direction D1 and smaller than the angle of the second inclined direction D4 with respect to the axial direction D1.

[0051] The inclination angle of the first inclination direction D3 with respect to the axial direction D1 is, for example, 20° or more and 30° or less. In the present embodiment, the inclination angle of the first inclination direction D3 with respect to the axial direction D1 is, for example, 25°. The inclination angle of the second inclination direction D4 with respect to the axial direction D1 is, for example, 70° or more and 90° or less. In the present embodiment, the inclination angle of the second inclination direction D4 with respect to the axial direction D1 is, for example, 90°. The inclination angle of the third inclination direction D5 with respect to the axial direction D1 is, for example, 30° or more and 45° or less. In the present embodiment, the inclination angle of the third inclination direction D5 with respect to the axial direction D1 is, for example, 37.8°.

[0052] Next, the positional relationship among the container 2 (operation unit 21 and storage cylinder 22), support member 3, pressing member 4, and screw cylinder 5 inside the feeding container 1 will be described. As shown in FIG. 4, the rear insertion portion 52, flange portion 58, and diameter-expanded portion 59 of the screw cylinder 5 are arranged between the storage cylinder 22 and the operation unit 21 along the radial direction of the container 2. The screw cylinder 5 is located outside the storage cylinder 22 in the radial direction. The container 2 (with respect to each of the operation unit 21 and the storage cylinder 22) is relatively rotatable with respect to the screw cylinder 5.

[0053] As shown in FIGS. 7, 9, and 11, in the storage cylinder 22, the first guide hole 221b and the second guide hole 221c extend along the axial direction D1. Therefore, the first protrusion 42 of the pressing member 4 that has entered the first guide hole 221b and the second protrusion 32 of the support member 3 that has entered the second guide hole 221c are not restricted from moving in the axial direction D1 with respect to the container 2 (storage cylinder 22). Accordingly, the support member 3 and the pressing member 4 are movable in the axial direction D1 with respect to the container 2 (storage cylinder 22).

[0054] As shown in FIGS. 9, 11, and 12, the first protrusion 42 passed through the first guide hole 221b of the container 2 (the housing cylinder 22) enters the first groove 5a of the screw cylinder 5 extending along the first inclination direction D3. The pressing member 4 rotates synchronously with the container 2 (each of the operation portion 21 and the housing cylinder 22). When the operation portion 21 and the screw cylinder 5 rotate relative to each other, the pressing member 4 rotates relative to the screw cylinder 5 together with the container 2. When the pressing member 4 rotates relative to the screw cylinder 5, the first protrusion 42 moves along the first groove 5a. Since the first inclination direction D3 is inclined with respect to the axial direction D1, when the pressing member 4 rotates relative to the screw cylinder 5 in a state where the first protrusion 42 enters the first inclined groove 5c, the pressing member 4 moves in the axial direction D1 with respect to the screw cylinder 5. In the present embodiment, since the second inclination direction D4 is the same direction as the circumferential direction D2, in a state where the first protrusion 42 enters the second inclined groove 5d, even if the pressing member 4 rotates relative to the screw cylinder 5, the pressing member 4 does not move in the axial direction D1 with respect to the screw cylinder 5.

[0055] The second protrusion 32 of the support member 3 passed through the second guide hole 221c of the container 2 (the housing cylinder 22) enters the second groove 5b of the screw cylinder 5 extending along the third inclination direction D5. The support member 3 rotates synchronously with the container 2. When the operation portion 21 and the screw cylinder 5 rotate relative to each other, the support member 3 rotates relative to the screw cylinder 5 together with the container 2. When the support member 3 rotates relative to the screw cylinder 5, the second protrusion 32 moves along the second groove 5b. Since the third inclination direction D5 is inclined with respect to the axial direction D1, in a state where the second protrusion 32 enters the third inclined groove 5e, when the support member 3 rotates relative to the screw cylinder 5, the support member 3 moves in the axial direction D1 with respect to the screw cylinder 5.

[0056] As described above, the inclination angle of the first inclination direction D3 with respect to the axial direction D1 is smaller than the inclination angle of the third inclination direction D5 with respect to the axial direction D1. Therefore, when the first protrusion 42 enters the first groove 5a, the second protrusion 32 enters the second groove 5b, and during the rotation of the screw cylinder 5, the pressing member 4, and the support member 3, the amount of movement of the pressing member 4 in the axial direction D1 with respect to the screw cylinder 5 is larger than the amount of movement of the support member 3 in the axial direction D1 with respect to the screw cylinder 5.

[0057] FIG. 14 is a perspective view of the inner cap 6. FIG. 15 is a rear view of the inner cap 6. As shown in FIGS. 4, 14, and 15, the inner cap 6 surrounds the screw cylinder 5. The inner cap 6 has a lid portion 61 that opens and closes the first opening 221a of the container 2 (accommodating cylinder 22), and a main body portion 62 located behind the lid portion 61. The main body portion 62 has, for example, a cylindrical shape. The main body portion 62 has a pair of flange portions 62a and a pair of side surface portions 62b. The pair of flange portions 62a are arranged at positions sandwiching the axis of the inner cap 6. The flange portion 62a has a smooth surface facing the outer side in the radial direction. The smooth surface has, for example, a rectangular shape. The pair of side surface portions 62b are arranged at positions sandwiching the axis of the inner cap 6. Each of the pair of side surface portions 62b is sandwiched between the pair of flange portions 62a in the circumferential direction D2.

[0058] For example, the outer surface of the side surface portion 62b is composed of three curved surfaces. The three curved surfaces are arranged along the circumferential direction D2 as viewed from the axial direction D1. As viewed from the axial direction D1, among the three curved surfaces, the curvature of each of the upper curved surface and the lower curved surface is larger than the curvature of a circle centered on the axis of the inner cap 6 and having a line segment from the axis of the inner cap 6 to the side surface portion 62b as the radius. The curvature of the curved surface sandwiched between the upper curved surface and the lower curved surface is smaller than the curvature of the circle.

[0059] The main body portion 62 has a front side opening 62c provided at the front end of the main body portion 62 and a rear side opening 62d provided at the rear end of the main body portion 62. For example, the inner diameter of the front side opening 62c is smaller than the inner diameter of the rear side opening 62d. The inner diameter of the front side opening 62c is larger than the outer diameter of the pressing member 4. The front side portion of the screw cylinder 5 is inserted into the main body portion 62 from the rear side opening 62d. By inserting the screw cylinder 5 into the main body portion 62 from the rear side opening 62d, the front side insertion portion 51 of the screw cylinder 5 is arranged inside the inner cap 6.

[0060] The main body portion 62 has an inner peripheral surface 62e extending forward from the rear opening 62d and a groove 62f provided on the inner peripheral surface 62e. The groove 62f corresponds to a recessed portion on the inner peripheral surface 62e. The groove 62f extends in the axial direction D1. For example, the main body portion 62 has a plurality (two as an example) of grooves 62f. For example, a pair of grooves 62f are arranged along the radial direction of the main body portion 62. A convex portion 55 (see FIG. 12) provided on the outer peripheral surface of the screw cylinder 5 fits into the groove 62f. When the screw cylinder 5 is inserted into the inner cap 6, the convex portion 55 fits into the groove 62f. Thereby, the screw cylinder 5 is engaged with the inner cap 6 so as to be rotatable in synchronization.

[0061] The main body portion 62 has a fitting portion 62k on the inner peripheral surface 62e where the screw cylinder 5 fits. The fitting portion 62k is, for example, a fitting concave portion extending in the circumferential direction D2. An annular convex portion 54 of the screw cylinder 5 fits into the fitting portion 62k. Thereby, the screw cylinder 5 is fitted to the inner cap 6 so as not to be movable in the axial direction.

[0062] The lid portion 61 opens and closes the first opening 221a in a state of being connected to the container 2. The lid portion 61 has a lid body 61a that closes the front opening 62c and a hinge portion 61b to which the lid body 61a is connected. The lid body 61a has, for example, a semi-circular shape. For example, the lid portion 61 has a pair of lid bodies 61a. For example, a pair of lid bodies 61a having a semi-circular shape are arranged along the radial direction of the main body portion 62. Thereby, the lid portion 61 has a circular shape when viewed from the axial direction D1.

[0063] As described above, in the lid portion 61, the pair of lid bodies 61a are arranged so as to have a circular shape. By rotating the pair of lid bodies 61a via the respective hinge portions 61b, the front opening 62c is opened and closed. The hinge portion 61b extends, for example, in the width direction of the main body portion 62 (a flange portion 62a as an example). The hinge portion 61b has, for example, a cylindrical shape. For example, the main body portion 62 has a pair of hinge fixing portions 62j to which both ends of the hinge portion 61b are connected.

[0064] The hinge fixing portion 62j is provided at the front end of the flange portion 62a. The hinge fixing portions 62j are provided at the respective widthwise ends of the flange portion 62a. The hinge portion 61b is connected to the hinge fixing portion 62j in a rotatable state with respect to the hinge fixing portion 62j. The hinge portion 61b is provided in front of the container 2 (accommodating cylinder 22). The lid portion 61 is made rotatable via the hinge portion 61b provided on the container 2 (for example, in front of the container 2). The lid portion 61 opens and closes the first opening 221a of the container 2 (accommodating cylinder 22) by rotating via the hinge portion 61b.

[0065] FIG. 16 is a perspective view of the lock member 7. FIG. 17 is a sectional view taken along line XVII-XVII of FIG. 16. As shown in FIGS. 4, 16, and 17, the lock member 7 has a cylindrical shape. For example, the inner cap 6 is inserted into the lock member 7. The lock member 7 covers the lid portion 61. For example, the lock member 7 has a rectangular shape when viewed from the axial direction D1. More specifically, the shape of the lock member 7 when viewed from the axial direction D1 is a rounded rectangular shape (a rounded square shape as an example). For example, the lock member 7 houses the screw cylinder 5 and is engaged with the screw cylinder 5 in the circumferential direction D2. The lock member 7 is made to be rotatable in synchronization with the screw cylinder 5.

[0066] FIG. 18 is a rear view of the lock member 7. As shown in FIGS. 4, 17, and 18, an inner cap accommodation region R1 extending rearward from the front end of the lock member 7 is provided inside the lock member 7. The inner cap 6 is accommodated in the inner cap accommodation region R1. For example, when viewed from the axial direction D1, the inner peripheral surface of the lock member 7 and the outer peripheral surface of the inner cap 6 have the same shape. The lock member 7 has a pair of flat surfaces 7g respectively facing the flange portion 62a (see FIG. 15) of the inner cap 6, and a pair of inner peripheral side surfaces 7h respectively facing the side surface portion 62b of the inner cap 6. The inner cap 6 is accommodated inside the lock member 7 from the rear side opening 7b located at the rear end of the lock member 7.

[0067] As described above, inside the lock member 7, the flange portion 62a of the inner cap 6 faces the flat surface 7g, and the side surface portion 62b of the inner cap 6 faces the inner peripheral surface 7h. At this time, the inner cap 6 and the lock member 7 rotate synchronously in the circumferential direction D2. The lock member 7 is movable relative to the inner cap 6 in the axial direction D1.

[0068] Incidentally, in the locked state where the opening of the lid portion 61 is restricted, the front end of the hinge fixing portion 62j abuts against the inner surface of the front end of the lock member 7. The lock member 7 has a lock portion 7c that restricts the opening of the lid portion 61. The lock portion 7c is located, for example, at the front end of the lock member 7. The lock portion 7c extends in the circumferential direction D2 so as to surround the second opening 7a. The lock portion 7c defines the second opening 7a.

[0069] The lock portion 7c abuts against the lid portion 61 to lock the lid portion 61. In the present embodiment, "locking" refers to a state in which the lock portion 7c abuts against the lid portion 61 and restricts the opening of the lid portion 61. When the lock member 7 moves forward with respect to the lid portion 61, the lock portion 7c separates from the lid portion 61. When the lock portion 7c separates from the lid portion 61, the locking of the lid portion 61 by the lock member 7 is released. By releasing the locking of the lid portion 61 by the lock member 7, the lid portion 61 becomes in an openable state, so that the cosmetic M can be exposed from the first opening 221a of the container 2.

[0070] The locking member 7 has a guide portion 7f for guiding the lid portion 61. The guide portion 7f projects radially inward of the locking member 7 from the peripheral wall of the locking member 7. As shown in FIG. 17, for example, the guide portion 7f has a shape (a right-angled triangular shape as an example) having an inclined portion inclined with respect to the axial direction D1. The guide portion 7f extends in a direction intersecting (orthogonal as an example) with the flat surface 7g. The guide portion 7f is connected to the flat surface 7g. The guide portion 7f having a right-angled triangular shape has a hypotenuse and a pair of adjacent sides extending from each of both ends of the hypotenuse. One of the pair of adjacent sides is connected to the flat surface 7g. The guide portion 7f extends, for example, from the inner peripheral surface of the locking member 7 to the second opening 7a. The length of the guide portion 7f in the axial direction D1 becomes longer as it approaches the inner peripheral surface of the locking member 7.

[0071] The locking member 7 has, for example, a plurality of guide portions 7f. For example, two guide portions 7f are arranged at positions sandwiching the flat surface 7g. And the two guide portions 7f are arranged side by side along the direction in which the pair of flat surfaces 7g face each other. For example, the locking member 7 has four guide portions 7f. In this case, when viewed from the axial direction D1, the four guide portions 7f may be arranged so as to form a rectangular shape.

[0072] The locking member 7 has a convex portion 7e provided so as to be connected to the rear end of the inner cap accommodation region R1.

[0073] The convex portion 7e is a portion with which a regulating portion 8 (see FIG. 2) into which the above-described screw cylinder 5 is inserted engages. The locking member 7 has, for example, a plurality of convex portions 7e. In the present embodiment, the locking member 7 has eight convex portions 7e. For example, when viewed from the axial direction D1, eight convex portions 7e are provided so that each corner portion of the locking member 7 is sandwiched by two convex portions 7e. The convex portion 7e projects from the inner peripheral surface of the locking member 7 toward the axis of the locking member 7. The convex portion 7e extends in the circumferential direction D2.

[0074] In the present embodiment, the outer contour of the cross-section intersecting the axial direction D1 on the rear side of the neck portion 212 of the operation portion 21 has a non-circular shape (rectangular shape). Therefore, when the locking member 7 is close to the operation portion 21, even if the locking member 7 attempts to rotate with respect to the operation portion 21, the inner surface of the locking member 7 abuts against the non-circular portion of the neck portion 212, making relative rotation of the locking member 7 with respect to the operation portion 21 impossible. On the other hand, the outer contour of the cross-section intersecting the axial direction D1 on the front side of the neck portion 212 has a circular shape. Therefore, when the locking member 7 is separated forward from the operation portion 21, when the locking member 7 attempts to rotate with respect to the operation portion 21, the inner surface of the locking member 7 does not abut against the operation portion 21, so relative rotation of the locking member 7 with respect to the operation portion 21 is possible.

[0075] FIG. 19 is a perspective view of the restricting portion 8. As shown in FIGS. 4 and 19, the restricting portion 8 is interposed between the screw cylinder 5 and the locking member 7. The restricting portion 8 restricts the amount of movement of the locking member 7 in the axial direction D1 with respect to the container 2 so that the locking member 7 does not move by a certain amount or more with respect to the container 2. For example, the restricting portion 8 faces the front end of the operation portion 21 along the axial direction D1.

[0076] For example, the restricting portion 8 has an annular shape. The restricting portion 8 has a pair of flat portions 8a facing each other and a pair of flat portions 8b facing each other in a direction different from the direction in which the pair of flat portions 8a face each other. The pair of flat portions 8a are arranged at positions sandwiching the axis of the restricting portion 8. The pair of flat portions 8b are arranged at positions sandwiching the axis of the restricting portion 8. For example, the pair of flat portions 8a and the pair of flat portions 8b are arranged at equal intervals along the circumferential direction D2. For example, in the pair of flat portions 8a and the pair of flat portions 8b, all of these four flat portions may have the same shape and size.

[0077] The restricting portion 8 has a plurality of corner portions 8c. In the present embodiment, the restricting portion 8 has four corner portions 8c. Each corner portion 8c is disposed between the flat portion 8a and the flat portion 8b. The restricting portion 8 has an outer groove 8d provided in the corner portion 8c. The outer groove 8d extends along the circumferential direction D2. The outer groove 8d extends from the flat portion 8a to the flat portion 8b. The outer groove 8d has a shape into which a convex portion 7e (see FIG. 17) formed on the inner surface of the lock member 7 enters. When the convex portion 7e enters the outer groove 8d, the restricting portion 8 engages with the lock member 7 in the axial direction D1.

[0078] That is, since the convex portion 7e has entered the outer groove 8d, when the lock member 7 moves along the axial direction D1, the restricting portion 8 moves along the axial direction D1 together with the lock member 7. When the lock member 7 rotates along the circumferential direction D2, the convex portion 7e contacts the flat portion 8a (or the flat portion 8b), so that the restricting portion 8 rotates along the circumferential direction D2 together with the lock member 7. Thus, the restricting portion 8 is capable of synchronous rotation with the lock member 7.

[0079] The restricting portion 8 has an inner groove 8e provided on the inner peripheral surface of the restricting portion 8. The inner groove 8e extends, for example, along the circumferential direction D2 on the inner peripheral surface of the restricting portion 8. A convex portion 56 or a convex portion 57 (see FIG. 12) of the screw cylinder 5 enters the inner groove 8e. The inner groove 8e has a bottom surface 8e1 and an inclined surface 8e2. The bottom surface 8e1 has a surface parallel to the outer peripheral surface of the rear insertion portion 52. The depth of the inner groove 8e is constant at the bottom surface 8e1. The inner groove 8e has a pair of inclined surfaces 8e2. The pair of inclined surfaces 8e2 are disposed at positions sandwiching the bottom surface 8e1 along the axial direction D1. The inclined surface 8e2 approaches the axis of the restricting portion 8 as it moves away from the bottom surface 8e1 in the axial direction D1. That is, the depth of the inner groove 8e at the inclined surface 8e2 becomes shallower as it moves away from the bottom surface 8e1 along the axial direction D1.

[0080] The convex portion 56 or the convex portion 57 that has entered the inner groove 8e moves along the axial direction D1 with respect to the inner groove 8e. When the convex portion 56 or the convex portion 57 moves with respect to the inner groove 8e, since the convex portion 56 or the convex portion 57 moves on the inclined surface 8e2, it can easily escape from the inner groove 8e. Thus, the restricting portion 8 can be moved with respect to the screw cylinder 5 in the axial direction D1.

[0081] However, the convex portion 56 or the convex portion 57 that has entered the inner groove 8e does not escape from the inner groove 8e unless an external force along the axial direction D1 is applied to the lock member 7. For example, in the feeding container 1 in the unlocked state, even if a weak external force along the axial direction D1 is applied to the lock member 7, the lock member 7 does not approach the operation portion 21. For example, when the user tries to bring the lock member 7 close to the operation portion 21 with a finger, the external force is applied to the feeding container 1, so that the convex portion 57 escapes from the inner groove 8e and the feeding container 1 changes from the unlocked state to the locked state. For example, when the user tries to move the lock member 7 forward with a finger, the external force is applied to the feeding container 1, so that the convex portion 56 escapes from the inner groove 8e and the feeding container 1 changes from the locked state to the unlocked state.

[0082] The restricting portion 8 has a front end surface 8f that intersects (orthogonal as an example) the axial direction D1. When the restricting portion 8 together with the lock member 7 moves forward with respect to the screw cylinder 5, the front end surface 8f contacts the rear end of the inner cap 6. When the front end surface 8f contacts the rear end of the inner cap 6, the lock member 7 and the restricting portion 8 can no longer move forward with respect to the screw cylinder 5. Thereby, the region where the lock member 7 and the restricting portion 8 can move along the axial direction D1 is limited to the range where the restricting portion 8 is located between the front end of the operation portion 21 and the rear end of the inner cap 6.

[0083] Next, with reference to FIGS. 20(a), 20(b), and 20(c), the operation of the feeding container 1 will be described in detail. FIG. 20(a) is a cross-sectional view of the feeding container 1 in the stored state and in the unlocked state. FIG. 20(b) is a cross-sectional view of the feeding container 1 in the use state. FIG. 20(c) is a cross-sectional view for explaining the operation when the feeding container 1 transitions from the use state to the stored state. As shown in FIGS. 4 and 20(a), in the feeding container 1 in the stored state and in the locked state, when the locking member 7 is moved along the axial direction D1 (for example, forward) with respect to the operation portion 21, the locking portion 7c separates from the lid portion 61. When the locking portion 7c separates from the lid portion 61, the lid portion 61 becomes openable and closable, and thus the feeding container 1 becomes unlocked. At this time, since the locking member 7 is separated forward with respect to the operation portion 21, it can rotate relative to the container 2.

[0084] In the feeding container 1 in the stored state and in the unlocked state, when the operation portion 21 is relatively rotated in one direction D2a with respect to the locking member 7, the operation portion 21 rotates relative to the locking member 7 and the screw cylinder 5.

[0085] Since the support member 3, the pressing member 4, and the housing cylinder 22 rotate synchronously, when the operating portion 21 rotates relative to the screw cylinder 5 in one direction D2a, the screw cylinder 5 rotates relative to the support member 3 and the pressing member 4. When the operating portion 21 rotates relative to the screw cylinder 5 in one direction D2a, the first protrusion 42 of the pressing member 4 moves forward along the first groove 5a. The first protrusion 42 moves from the first inclined groove 5c toward the second inclined groove 5d before or simultaneously with the pressing member 4 pushing up the lid portion 61. In the feeding container 1 in the housed state, as the first protrusion 42 moves forward along the first inclined groove 5c, the second protrusion 32 of the support member 3 moves forward along the third inclined groove 5e. Since the angle of the first inclined direction D3 in which the first inclined groove 5c extends with respect to the axial direction D1 is smaller than the angle of the third inclined direction D5 in which the third inclined groove 5e extends with respect to the axial direction D1, the pressing member 4 moves in the axial direction D1 (moves forward) with respect to the support member 3. That is, when the first protrusion 42 is in the first inclined groove 5c, the moving speed of the pressing member 4 in the axial direction D1 is faster than the moving speed of the support member 3 in the axial direction D1. When the pressing member 4 moves forward with respect to the support member 3, the pressing member 4 pushes up the lid portion 61 to open the first opening 221a.

[0086] When the operating portion 21 is further rotated relative to the locking member 7, as shown in FIG. 20(b), the pressing member 4 is fed out from the second opening 7a of the locking member 7. The first protrusion 42 of the pressing member 4 moves from the first inclined groove 5c toward the second inclined groove 5d before or simultaneously with the pressing member 4 pushing up the lid portion 61. That is, when the pressing member 4 pushes up (reaches) the lid portion 61, the first protrusion 42 is located in the first inclined groove 5c and starts to move from the first inclined groove 5c to the second inclined groove 5d.

[0087] After the first protrusion 42 moves from the first inclined groove 5c to the second inclined groove 5d and then the operation portion 21 rotates relative to the locking member 7, the first protrusion 42 moves along the second inclined groove 5d, and the second protrusion 32 of the support member 3 moves along the third inclined groove 5e. Since the angle of the second inclined direction D4 in which the second inclined groove 5d extends with respect to the axial direction D1 is larger than the angle of the third inclined direction D5 in which the third inclined groove 5e extends with respect to the axial direction D1, the support member 3 moves in the axial direction D1 (moves forward) with respect to the pressing member 4. That is, when the first protrusion 42 is in the second inclined groove 5d, the moving speed of the support member 3 in the axial direction D1 is faster than the moving speed of the pressing member 4 in the axial direction D1. When the support member 3 moves forward with respect to the pressing member 4, the cosmetic M is fed out from the opening formed at the front end of the pressing member 4.

[0088] In this way, when the screw cylinder 5 and the operation portion 21 rotate relative to each other in the one direction D2a, the first protrusion 42 of the pressing member 4 moves along the first groove 5a of the screw cylinder 5, and the pressing member 4 pushes up the lid portion 61 to open the first opening 221a. Then, the second protrusion 32 of the support member 3 moves along the second groove 5b of the screw cylinder 5 and the support member 3 moves forward, so that the cosmetic M is fed out from the first opening 221a. Thereby, the feeding container 1 changes from the accommodated state to the use state.

[0089] When the screw cylinder 5 and the operation portion 21 rotate relative to each other in the opposite direction D2b, as shown in FIG. 20(c), the second protrusion 32 of the support member 3 moves backward along the second groove 5b of the screw cylinder 5, the support member 3 moves in the axial direction D1, and the cosmetic M immerses into the first opening 221a. The first protrusion 42 of the pressing member 4 moves from the second inclined groove 5d of the screw cylinder 5 toward the first inclined groove 5c, and the second protrusion 32 moves backward along the third inclined groove 5e. At this time, the first protrusion 42 is located in the second inclined groove 5d, and the moving speed of the support member 3 in the axial direction D1 is faster than the moving speed of the pressing member 4 in the axial direction D1, so that the support member 3 moves in the axial direction D1 (moves backward) with respect to the pressing member 4. When the support member 3 moves backward with respect to the pressing member 4, the cosmetic M moves backward with respect to the pressing member 4 together with the support member 3.

[0090] When the screw cylinder 5 and the operation part 21 further rotate relative to each other in the opposite direction D2b, the first protrusion 42 moves from the second inclined groove 5d to the first inclined groove 5c. Then, as the first protrusion 42 moves rearward along the first inclined groove 5c, the second protrusion 32 moves rearward along the third inclined groove 5e. At this time, since the first protrusion 42 is located in the first inclined groove 5c and the moving speed of the pressing member 4 in the axial direction D1 is faster than the moving speed of the support member 3 in the axial direction D1, the pressing member 4 moves (moves rearward) in the axial direction D1 with respect to the support member 3. The pressing member 4 starts to move (move rearward) in the axial direction D1 toward the support member 3 before the support member 3 reaches the bottom dead center which is its descending limit. In this specification, the "bottom dead center" refers to the position of the support member 3 at the limit where the support member 3 can move rearward.

[0091] When the screw cylinder 5 and the operation part 21 further rotate relative to each other in the opposite direction D2b, the cosmetic M is accommodated in the accommodation cylinder 22, and as the pressing member 4 moves rearward away from the lid part 61, the lid part 61 closes. As a result, the feeding container 1 changes from the use state to the accommodation state. Then, by pushing the lock member 7 toward the operation part 21, the feeding container 1 changes from the unlocked state to the locked state. Since the guide part 7f protrudes radially inward of the lock member 7, when the lock member 7 is pushed toward the operation part 21, the guide part 7f contacts the lid part 61 of the inner cap 6. The guide part 7f has a function of guiding the lid part 61 to the lock part 7c and gradually closing the lid part 61. Therefore, when the guide part 7f contacts the lid part 61, the first opening 221a is gradually closed. In this embodiment, since the guide part 7f has a right triangle shape, as the front end of the guide part 7f contacts the lid part 61 starting from the rear end of the guide part 7f, the lid part 61 gradually closes the first opening 221a.

[0092] Next, the effects obtained from the dispensing container 1 according to the present embodiment will be described. As shown in FIGS. 4, 20(a), 20(b), and 20(c), in the dispensing container 1, the container 2 has a storage portion 221 for storing the cosmetic M and a first opening 221a through which the cosmetic M is exposed, and the first opening 221a is opened and closed by the lid portion 61. The dispensing container 1 includes a locking member 7, and the locking member 7 locks the lid portion 61 when the lid portion 61 closes the first opening 221a. By the locking member 7 locking the lid portion 61, the state where the lid portion 61 closes the first opening 221a is maintained, so that it is possible to prevent the first opening 221a from opening unintentionally by the user of the dispensing container 1. The locking member 7 releases the lock of the lid portion 61 when it moves in the axial direction D1 with respect to the container 2, and at this time, the cosmetic M can be exposed from the first opening 221a. Therefore, it is possible to prevent the lock of the lid portion 61 from being released unless the user moves the locking member 7 in the axial direction D1, and at this time, it is possible to regulate the exposure of the cosmetic M from the first opening 221a. As a result, it is possible to prevent the cosmetic M from being exposed from the first opening 221a unintentionally, so that it is possible to prevent the objects located around the dispensing container 1 from being soiled.

[0093] The locking member 7 has a cylindrical shape into which the container 2 is inserted. The container 2 has an operation portion 21 that is operated when the container 2 rotates relative to the locking member 7 in order to dispense the cosmetic M. In a state where the locking member 7 locks the lid portion 61, the operation portion 21 is made non-rotatable relative to the locking member 7. When the lock of the lid portion 61 by the locking member 7 is released, the operation portion 21 is made rotatable relative to the locking member 7. In addition to the fact that the cosmetic M is difficult to be exposed by the lid portion 61 being locked by the locking member 7, since the operation portion 21 is made non-rotatable relative to the locking member 7, it is possible to prevent the cosmetic M from being dispensed unintentionally. Therefore, it is possible to further prevent the cosmetic M from being exposed contrary to the intention of the user.

[0094] The lid portion 61 is rotatable via a hinge portion 61b provided on the container 2. The lid portion 61 opens and closes the first opening 221a by rotating via the hinge portion 61b. The locking member 7 has a second opening 7a through which the cosmetic M fed out from the first opening 221a appears, and a locking portion 7c that abuts against the lid portion 61 to lock the lid portion 61. The lid portion 61 is rotatable via the hinge portion 61b. The locking member 7 has a locking portion 7c that abuts against the lid portion 61 to lock the lid portion 61. Therefore, when the lid portion 61 rotates and the locking portion 7c abuts against the lid portion 61 along the direction in which the first opening 221a is closed, the lid portion 61 can be easily locked. As a result, it is possible to prevent the cosmetic M from being exposed against the intention of the user. Further, with the lid portion 61 rotated and the first opening 221a opened, the cosmetic M passing through the first opening 221a can be exposed through the second opening 7a. Therefore, the cosmetic M can be exposed without removing the locking member 7.

[0095] As described above, the embodiments of the dispensing container according to the present disclosure have been described. However, the dispensing container according to the present disclosure is not limited to the above-described embodiments, and may be further modified within the scope of the gist described in the claims. That is, the shape, size, material, number, and arrangement mode of each part of the dispensing container according to the present disclosure can be appropriately changed within the scope of the above gist.

[0096] The lid portion may open and close the first opening 221a while being connected to at least one of the locking member 7, the container 2, and the screw cylinder 5. For example, the lid portion may open and close the first opening 221a while being connected to the locking member 7. In the dispensing container according to the modification, instead of the inner cap 6 having the lid portion 61 and the locking member 7 having the guide portion 7f, it may have a lid portion connected to the locking member 7. The lid portion may be rotatable by a hinge portion provided on the inner peripheral surface of the locking member 7. The lid portion may be closed by at least one of the front end of the inner cap 6, the front end of the screw cylinder 5, and the front end of the container 2 abutting toward the front end of the locking member 7. On the other hand, the lid portion may be opened by the front end of the inner cap 6, the front end of the screw cylinder 5, and the front end of the container 2 being separated from the front end of the locking member 7.

[0097] The timing at which the first protrusion 42 moves can be changed as appropriate. The same applies to the second protrusion 32 of the support member 3.

[0098] In the above-described embodiment, an example has been described in which the accommodating portion 221 of the container 2 has the first guide hole 221b and the second guide hole 221c, the pressing member 4 has the first protrusion 42 inserted into the first guide hole 221b, and the support member 3 has the second protrusion 32 inserted into the second guide hole 221c. However, the accommodating portion may not have a guide hole, and the pressing member and the support member may not have protrusions. Thus, the configurations of the container, the pressing member, and the support member can be changed as appropriate. The configuration of the screw cylinder is not limited to the screw cylinder 5 described above and can be changed as appropriate.

[0099] In the above-described embodiment, the inner cap 6 having the hinged lid portion 61 that is rotatable via the hinge portion 61b has been described. However, the lid portion is not limited to the hinged lid portion, and the type of the lid portion is not particularly limited as long as it has a structure capable of opening and closing the first opening of the container. Further, the lid portion may not be provided on the inner cap 6. For example, instead of the inner cap 6, the lock member 7 may have a lid portion. In this case, when the lock member 7 is moved in the axial direction D1 with respect to the container 2 (operation portion 21), the lock of the lid portion may be released, and the lid portion may be opened by the weight of the lid portion. Thus, the type of the component having the lid portion and the means for opening and closing the lid portion can be appropriately changed.

[0100] In the above-described embodiment, the feeding container 1 has been described, which includes the container 2 having the operation portion 21 that is relatively rotatable with respect to the lock member 7, and in the locked state, the operation portion 21 is made non-rotatable relative to the lock member 7, and in the unlocked state, the feeding and retracting of the cosmetic M are performed by the relative rotation of the operation portion 21 with respect to the lock member 7. However, the lock member 7 may be moved in the axial direction D1 with respect to the container 2 due to the screwing action caused by the relative rotation between the lock member 7 and the operation portion 21, and the lock of the lid portion 61 may be released. Further, the feeding container may not feed the cosmetic by relative rotation. Instead of relative rotation, the feeding container may have a feeding mechanism that is a mechanical extrusion mechanism such as a knock type, and the cosmetic may be extruded by the feeding mechanism, or it may be provided with a squeezing type feeding mechanism. Thus, the type of the feeding mechanism can be appropriately changed.
