Description

[Technical Field]

[0001] The present invention relates to a powder container. [Background technology]

[0002] Conventionally, there has been known a powder container that includes a container body that stores powdered contents, an inner lid member that closes the mouth of the container body, a cap that covers the inner lid member, and a puff for applying the contents (see, for example, Patent Document 1). In Patent Document 1, the puff is pressed against a mesh sheet provided in the inner lid member, and the contents that pass through the openings in the mesh sheet are attached to the puff, making it possible to apply the contents using the puff. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2018-89013 Summary of the Invention [Problem to be solved by the invention]

[0004] Although the powder container of Patent Document 1 is designed to be used with a puff, there are cases where it is desirable to apply the contents using another applicator, such as a brush. In such cases, the contents are often poured from the powder container into a separate dish or the like to collect the contents, and then a brush is brought into contact with the collected contents to adhere the contents to the brush. However, when pouring the contents from an opening dedicated to the puff, as in Patent Document 1, there are issues such as the time-consuming task of collecting the contents in a separate dish or the possibility of the contents scattering, making the work difficult. For this reason, a powder container that can easily dispense and store its contents is desired.

[0005] In view of the above, an object of the present invention is to provide a powder container that allows the contents to be easily poured out and stored. [Means for solving the problem]

[0006] The powder container comprises a container body for storing powdered contents, a container portion having an inner lid member for closing the mouth of the container body, and a cap that screws onto a threaded portion on the outer periphery of the container portion to cover the inner lid member, the inner lid member having an outlet for pouring out the contents, and is provided with a vibration generating unit that generates vibrations in response to relative rotation between the cap and the container portion when the screwing is released, and the vibration generating unit comprises a plurality of first convex portions arranged circumferentially on either the outer periphery of the container body or the inner periphery of the cap, and a second convex portion that is provided on the other of the outer periphery of the container body or the inner periphery of the cap and moves circumferentially while climbing over the first convex portions due to the relative rotation. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide a powder container that can easily pour out and store the contents. [Brief explanation of the drawings]

[0009] Hereinafter, an embodiment of a powder container according to the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view showing a powder container 10 according to an embodiment of the present invention.

[0010] The powder container 10 includes a container portion 11 for storing the content P, a cap 12 for covering the top of the container portion 11, and a puff 13 for applying the content P. The contents P are powders, and are not particularly limited to, for example, cosmetics.

[0011] The container part 11 includes a container body 14 for storing the contents P, and an inner lid member 15 attached to the top of the container body 14. The container body 14 includes a cylindrical bottle 16 with a bottom and a mouth member 17 fixed to the top of the bottle 16 .

[0012] 2A is a plan view of the bottle 16 as seen from above, and FIG. 2B is a side view of the bottle 16. 1 to 2B, bottle 16 includes a bottom wall 18, a cylindrical body 19 extending upward from the peripheral edge of bottom wall 18, and a cylindrical bottle mouth 20 extending upward from the upper end of body 19. The space inside bottle 16 is storage space 16a for storing content P. 1, the powder container 10 is shown in an upright position, with the powder container 10 placed upright so that the axis 20a of the bottle mouth 20 is oriented vertically. The axis 20a is the center line of the bottle mouth 20 and is arranged coaxially with the axis of the body 19.

[0013] The body 19 includes a lower body 19a extending upward from the bottom wall 18, and an upper body 19b provided above the lower body 19a. The upper body portion 19b is cylindrical and has an outer diameter smaller than that of the lower body portion 19a.

[0014] A first protrusion 21 that protrudes radially outward is provided on a part of the outer periphery of the upper body portion 19b. A plurality of first protrusions 21 are provided and arranged at equal intervals in the circumferential direction of the body portion 19. In detail, Upper body portion 19b is provided with one-side convex portion group 21a, which is made up of a plurality of first convex portions 21 arranged in a row, and another-side convex portion group 21b, which is made up of a plurality of first convex portions 21 arranged in a row at a position facing one-side convex portion group 21a in a plan view (FIG. 2A). One-side convex portion group 21a and another-side convex portion group 21b are arranged symmetrically in FIG. 2A.

[0015] Additionally, a pair of circumferential portions 22a, 22b, which are not provided with first protrusions 21, are provided between one-side protrusion group 21a and the other-side protrusion group 21b on the outer periphery of upper body portion 19b. Circumferential portions 22a and 22b are symmetrical. First protrusions 21 protrude radially outward from circumferential portions 22a, 22b, which form the basic outer diameter of the outer periphery of upper body portion 19b.

[0016] The bottle mouth 20 is cylindrical and extends upward from the upper end of the body 19. The outer diameter of the bottle mouth 20 is smaller than the outer diameter of the upper body 19b. A plurality of positioning portions 20b for positioning the mouth member 17 are provided on the outer periphery of the lower part of the bottle mouth portion 20. The positioning portions 20b are grooves formed on the outer periphery of the bottle mouth portion 20. An annular rib 20c is provided on the outer periphery of the bottle mouth 20 above the positioning portion 20b, protruding radially outward.

[0017] Fig. 3A is a plan view of the mouth member 17 as seen from above. Fig. 3B is a side view of the mouth member 17. A part of Fig. 3B shows a cross section taken along line III-III in Fig. 3A. 1 to 3B, the mouth member 17 comprises a cylindrical tubular portion 24, an annular flange portion 25 extending radially inward from the upper end of the tubular portion 24, and a lid portion 26 extending radially inward from a circumferential portion of the flange portion 25. The mouth member 17 also has an opening 27 defined by the inner periphery of the flange portion 25 and the inner periphery of the lid portion 26 .

[0018] The mouth member 17 has a plurality of positioning protrusions 24a that protrude radially inward from the inner periphery of the lower part of the cylindrical portion 24. The positioning protrusions 24a are provided at positions corresponding to the positioning portions 20b of the bottle mouth portion 20. An annular groove 24b is provided on the inner periphery of the cylindrical portion 24 above the positioning protrusion 24a, with which the annular rib 20c engages.

[0019] The cylindrical portion 24 is provided on its outer periphery with an annular claw portion 24c that protrudes radially outward. Furthermore, a pair of stopper portions 24d, 24e protruding radially outward are provided above the annular claw portion 24c on the outer periphery of the cylindrical portion 24. The pair of stopper portions 24d, 24e are provided at equal intervals in the circumferential direction of the cylindrical portion 24 and are positioned opposite each other. The flange portion 25 includes an annular lower surface rib 25a extending downward from the lower surface of the flange portion 25.

[0020] The mouth member 17 is fixed to the bottle mouth 20 with the tubular portion 24 fitted onto the outer periphery of the bottle mouth 20 and the lower surface of the flange portion 25 abutting against the upper surface of the bottle mouth 20. Furthermore, the positioning projection 24a of the mouth member 17 is engaged with the positioning portion 20b of the bottle mouth 20, thereby restricting rotation of the mouth member 17. The mouth member 17 cannot rotate relative to the bottle mouth 20. Furthermore, the annular rib 20c of the bottle mouth 20 engages with the annular groove 24b of the cylindrical portion 24, and the lower surface rib 25a abuts against the inner periphery of the bottle mouth 20.

[0021] The container body 14 is formed by fixing the mouth member 17 to the bottle mouth portion 20 of the bottle 16. The mouth portion 14a (FIG. 1) of the container body 14 is composed of a bottle mouth portion 20 and a mouth member 17. The lid portion 26 of the mouth member 17 extends radially inward beyond the inner periphery of the bottle mouth portion 20 .

[0022] Fig. 4A is a plan view of the inner cover member 15 as seen from above. Fig. 4B is a side view of the inner cover member 15. A part of Fig. 4B shows a cross section taken along line IV-IV in Fig. 4A. 1 to 4B, the inner lid member 15 comprises a disk-shaped top wall portion 30, a cylindrical peripheral wall portion 31 extending downward from the peripheral edge of the top wall portion 30, a plurality of support pieces 32 extending upward from the upper surface of the top wall portion 30, a spout 33 penetrating the top wall portion 30, and a threaded portion 34 formed on the outer periphery of the peripheral wall portion 31. In addition, the inner cover member 15 is provided with an annular anti-slip protrusion 35 that protrudes radially inward from the inner circumference of the lower part of the peripheral wall portion 31, and stopper abutment portions 36a, 36b that protrude radially inward from the inner circumference of the peripheral wall portion 31 above the anti-slip protrusion 35. Furthermore, the inner lid member 15 is provided with a protrusion 37 that protrudes radially outward from the upper end of the threaded portion .

[0023] The top wall portion 30 includes an annular outer peripheral top wall 30a that covers the flange portion 25 and the lid portion 26 of the mouth portion 14a from above, and a bulge portion 30b provided in the center of the top wall portion 30. The outer peripheral top wall 30 a is a horizontal plate-like portion that extends along the flange portion 25 . In a plan view, the bulging portion 30b is a circular convex portion that protrudes downward toward the inside of the container body 14. The bulging portion 30b bulges in a curved shape so as to become lower from the inner peripheral edge of the outer peripheral top wall 30a toward the center of the top wall portion 30.

[0024] The support pieces 32 extend upward from the outer peripheral top wall 30a. A plurality of support pieces 32 are provided at equal intervals in the circumferential direction and are arranged to surround the bulging portion 30b from the periphery. The outlet 33 is provided in the outer peripheral top wall 30a, radially outward of the support piece 32. The outlet 33 is an elongated hole extending in the circumferential direction of the top wall portion 30. Although the outlet 33 is preferably elongated, the outlet 33 is not limited to an elongated hole shape and may be, for example, a circular hole. The threaded portion 34 is a male threaded portion that screws into the inner periphery of the cap 12 . The stopper contact portions 36a, 36b are provided as a pair at equal intervals in the circumferential direction and are positioned opposite each other.

[0025] The inner lid member 15 is attached to the mouth portion 14a with the peripheral wall portion 31 fitted to the outer periphery of the mouth member 17 (the outer periphery of the mouth portion 14a) and the lower surface of the outer peripheral top wall 30a abutting the upper surface of the flange portion 25. Furthermore, the inner lid member 15 is prevented from coming off in the upward direction by the retaining projections 35 coming into contact with the annular claw portions 24c of the mouth member 17 from below. The inner lid member 15 is rotatable relative to the opening portion 14a around an axis 20a.

[0026] The container part 11 is formed by attaching the inner lid member 15 to the container body 14. The cap 12 is removably attached to the container part 11 by screwing onto a threaded portion 34 provided on the outer periphery of the inner lid member 15 at the top of the container part 11. The puff 13 is supported by the inner lid member 15 so as to fit onto the inner periphery of the plurality of support pieces 32 and abut against the upper surface of the bulging portion 30b, and is stored inside the cap 12. The plurality of support pieces 32 form a puff storage section capable of storing the puff 13.

[0027] Referring to FIG. 1, the cap 12 includes a cap top wall portion 40 that covers the inner lid member 15 from above, and a cylindrical cap peripheral wall portion 41 that extends downward from the peripheral edge of the cap top wall portion 40. The cap peripheral wall portion 41 covers the container portion 11 from the mouth portion 14a to the upper body portion 19b from the radially outer side. An internal thread 42 that screws onto the thread 34 is provided on the inner periphery of the upper part of the cap peripheral wall 41. When the puff 13 is supported by the support piece 32, a gap is formed between the lower surface of the cap top wall 40 and the upper surface of the puff 13.

[0028] Fig. 5 is a cross-sectional view taken along line BB' in Fig. 1. The cross section in Fig. 1 corresponds to the cross section taken along line BB' in Fig. 5. 1 and 5, a pair of second protrusions 43a, 43b protruding radially inward is provided below the female thread portion 42 on the inner periphery of the cap peripheral wall portion 41. The pair of second protrusions 43a, 43b are provided at equal intervals in the circumferential direction, and the second protrusions 43a and 43b face each other. The second protrusions 43a and 43b are provided at height positions in the height direction of the powder container 10 that overlap with the first protrusion 21 and the circumferential portions 22a and 22b of the upper body portion 19b.

[0029] The first protrusion 21 and the second protrusions 43a, 43b constitute a vibration generating unit 45 that generates vibrations in the container unit 11 in accordance with the relative rotation of the cap 12 and the container unit 11 when the cap 12 is unscrewed. In Fig. 5, the rotation direction of the cap 12 when the female threaded portion 42 of the cap 12 is unscrewed from the threaded portion 34 of the container unit 11 is illustrated as the unscrewing direction R. The unscrewing direction R is counterclockwise in Fig. 5.

[0030] In detail, when the cap 12 rotates relative to the bottle 16 of the container portion 11, the second convex portions 43a, 43b move circumferentially while climbing over the one-side convex portion group 21a and the other-side convex portion group 21b, and vibration is generated when the second convex portions 43a, 43b climb over the one-side convex portion group 21a and the other-side convex portion group 21b. Furthermore, the first protrusions 21 are not provided on the circumferential portions 22a, 22b, and the second protrusions 43a, 43b are spaced radially outward from the circumferential portions 22a, 22b and do not contact the circumferential portions 22a, 22b. Therefore, when the second protrusions 43a, 43b move in the circumferential direction while facing the circumferential portions 22a, 22b, no vibration is generated by the vibration generating unit 45.

[0031] The one-side convex portion group 21a and the other-side convex portion group 21b constitute a vibration section in which vibration is generated by contact between the first convex portion 21 and the second convex portions 43a, 43b. The circumferential portions 22a and 22b constitute a non-vibration section where no vibration occurs because the first protrusion 21 is not provided on the upper body portion 19b.

[0032] Figure 6 is an enlarged view of the portion indicated by the symbol D1 in Figure 1, which is the portion where the threaded portion 34 and the female threaded portion 42 are threaded together. Also, Figure 6 shows the VV cross section of the inner lid member 15 in Figure 4A. 6, a protrusion 37 is provided on the upper end of the threaded portion 34 at a portion facing the upper end of the female threaded portion 42. The protrusion 37 is provided on the valley portion of the threaded portion 34 facing the upper end of the female threaded portion 42. When the cap 12 is completely screwed onto the threaded portion 34, the protrusion 37 abuts against the top of the female threaded portion 42 in the radial direction of the threaded portion 34. This causes the threaded portion 34 and the female threaded portion 42 to be firmly screwed together.

[0033] Here, the operation of the powder container 10 when dispensing the content P will be described. FIG. 1 shows the powder container 10 in a stored state with the female threaded portion 42 of the cap 12 fully threaded onto the threaded portion 34 of the container portion 11. Fig. 7 is a cross-sectional view taken along the line AA' in Fig. 1. The cap 12 is not shown in Fig. 7. Fig. 8 is a cross-sectional view showing the powder container 10 in an inverted state during storage.

[0034] 1, 7, and 8, when the powder container 10 is in the above-described storage state, the lid 26 covers the spout 33 from the inside of the storage space 16a, closing the spout 33. Therefore, the contents P are sealed within the storage space 16a.

[0035] When dispensing the contents P, the powder container 10 is placed in an inverted position with the spout 33 pointing downward, as shown in Figure 8, and in this state, the cap 12 is unscrewed, thereby dispensing the contents P from the spout 33. In FIG. 8, the spout 33 is closed by the lid 26, so the contents P are not poured out from the spout 33 even in the inverted state.

[0036] Fig. 7 shows the release direction R of the cap 12. When the powder container 10 is in the storage state shown in Figs. 1 and 8, the stopper abutment portion 36a of the inner lid member 15 abuts against the stopper portion 24d of the mouth member 17 in the direction opposite to the release direction R, as shown in Fig. 7. Also, when the powder container 10 is in a storage state, as shown in Figure 7, at the stopper portion 24e located opposite the stopper portion 24d, the stopper abutment portion 36b of the inner lid member 15 abuts against the stopper portion 24e in the direction opposite to the release direction R. 7, the stopper abutment portions 36a, 36b abut against the stopper portions 24d, 24e in the direction opposite to the release direction R, and therefore the rotation of the inner lid member 15 in the direction opposite to the release direction R is restricted by the stopper portions 24d, 24e. Also, in the state of FIG. 7, the rotation of the inner lid member 15 in the release direction R is not restricted by the stopper portions 24d, 24e, and therefore the inner lid member 15 can rotate in the release direction R.

[0037] Also, as shown in Figure 5, in the above-mentioned storage state, the second convex portion 43a is located in the middle of the non-vibration section facing the circumferential portion 22a, and the second convex portion 43b is located in the middle of the non-vibration section facing the circumferential portion 22b.

[0038] Fig. 9 is a cross-sectional view taken along line AA' in Fig. 1, showing a state in which the cap 12 and inner lid member 15 are rotated in the release direction R from the state in Fig. 7. The cap 12 is not shown in Fig. 9. Fig. 10 is a cross-sectional view corresponding to the cross-section CC' in Fig. 9, showing the powder container 10 in an inverted state. Fig. 11 is a cross-sectional view taken along line BB' in Fig. 1 in the state in Fig. 9. When the cap 12 is rotated in the release direction R from the storage state shown in Figure 7, the inner lid member 15 and the cap 12 rotate together in the release direction R and rotate relative to the opening portion 14a. The inner lid member 15 is connected to the cap 12 by the female thread portion 42 and the thread portion 34 being threadedly engaged, and therefore rotates together with the cap 12 in the release direction R.

[0039] FIG. 9 shows a state in which the cap 12 has been rotated to a rotation restricted state in which the rotation of the inner lid member 15 in the release direction R is restricted by the stopper portions 24d and 24e. When the cap 12 is rotated approximately 170° in the release direction R from the state shown in Fig. 7, as shown in Fig. 9, the stopper abutment portion 36b abuts against the stopper portion 24d in the release direction R, and the stopper abutment portion 36a abuts against the stopper portion 24e in the release direction R. As a result, the rotation of the inner lid member 15 in the release direction R is restricted by the stopper portions 24d and 24e.

[0040] When the cap 12 is rotated in the release direction R from the state shown in Figure 7, the spout 33 of the inner lid member 15 also rotates in the release direction R, and when it has rotated approximately 30 degrees from the state shown in Figure 7, the spout 33 moves away from the lid portion 26 in the circumferential direction, as shown by the virtual line in Figure 7, and the spout 33 opens. When the cap 12 is further rotated in the release direction R, the spout 33 moves in the release direction R while remaining in the open state, and when the rotation angle reaches approximately 170° as shown in Figure 9, the spout 33 enters the rotation restricted state. Even in the rotation restricted state, the spout 33 remains in the open state.

[0041] Referring to FIG. 5, in the storage state, the second convex portions 43a and 43b are located on the circumferential portions 22a and 22b, which are non-vibration sections. Then, when the cap 12 is rotated approximately 30 degrees in the release direction R from the state shown in Figure 5, the second convex portion 43a begins to contact the one-side convex portion group 21a, and the second convex portion 43b begins to contact the other-side convex portion group 21b, and the second convex portions 43a, 43b become positioned in the vibration section. In detail, the second convex portions 43a, 43b move into the vibration section after the spout 33 opens, as shown by the imaginary lines in Fig. 7. That is, when the cap 12 rotates in the release direction R, while the spout 33 is closed, the second convex portions 43a, 43b are located in the non-vibration section and no vibration occurs, and after the spout 33 opens, the second convex portions 43a, 43b are located in the vibration section and vibration occurs.

[0042] 11 shows an enlarged view of the second convex portion 43a moving through the vibration section, shown by imaginary lines. As shown in this enlarged view, when the second convex portion 43a moves in the circumferential direction (the direction of the release direction R), the trajectory T of the tip of the second convex portion 43a overlaps with the first convex portion 21. Therefore, when the cap 12 rotates, the second convex portion 43a moves over the first convex portion 21, causing elastic deformation of the cap 12 and generating vibrations. When vibrations are generated by the vibration generating unit 45 in this way, the vibrations are transmitted to the contents P in the storage space 16a, facilitating the movement of the contents P and facilitating the pouring of the contents P from the pouring outlet 33.

[0043] After the spout 33 is opened, if the cap 12 is further rotated in the release direction R to the rotation restricted state shown in FIG. 9, the second convex portions 43a, 43b move on the vibration section while the spout 33 is open. In this state, the spout 33 moves in the circumferential direction while the spout 33 is open and vibration is being generated by the vibration generating unit 45. Therefore, by rotating the cap 12 in the release direction R, the contents P can be effectively poured out from the spout 33. The contents P poured out from the spout 33 accumulate on the inner surface of the cap 12, as shown in FIG. 10. In the rotation restricted state of FIG. 9, the second protrusion 43a is located on the circumferential portion 22b, and the second protrusion 43a is located on the circumferential portion 22a.

[0044] FIG. 12 is a cross-sectional view showing a state in which the cap 12 is rotated in the release direction R from the rotation restricted state shown in FIG. FIG. 12 shows a state in which the cap 12 has been rotated approximately one full turn in the release direction R from the rotation restricted state. 9 and 10, rotation of the inner lid member 15 in the release direction R is stopped by the stopper portions 24d, 24e. When the cap 12 is rotated in the release direction R from this state, the female thread portion 42 of the cap 12 and the thread portion 34 of the container portion 11 are disengaged, and only the cap 12 rotates in the release direction R. The cap 12 in FIG. 12 has moved downward relative to the cap 12 in FIG. 10 by an amount equivalent to approximately one rotation of the cap 12. Furthermore, because rotation of the inner lid member 15 is stopped, even if the cap 12 is rotated in the release direction R from the rotation restricted state, the position of the spout 33 does not change, and the spout 33 remains open.

[0045] 11, when the cap 12 is rotated approximately once in the release direction R from the rotation restricted state of Fig. 11, the second convex portions 43a, 43b rotate approximately once in the release direction R, pass through the vibration section and the non-vibration section, and return to the state of Fig. 11. In other words, vibrations are generated by the vibration generating unit 45 even while the cap 12 is rotated approximately once in the release direction R from the rotation restricted state, and the vibrations cause the content P to be efficiently poured out from the pouring outlet 33. The contents P poured out from the pouring outlet 33 accumulates on the inner surface of the cap 12 as shown in FIG.

[0046] 12, the female thread portion 42 is completely disengaged from the thread portion 34, and the cap 12 is removed from the container portion 11. The contents P remain on the inner surface of the cap 12 that has been removed from the container portion 11. In this way, when the powder container 10 is inverted and the cap 12 is rotated in the release direction R to remove it from the container part 11, the contents P automatically accumulate on the inner surface of the cap 12. This allows the user to use the cap 12 as a tray for the contents P, eliminating the need to prepare a separate tray, and allowing the contents P that automatically accumulates when the cap 12 is removed to be used immediately. Furthermore, because the contents P fall and accumulate in the cap 12 while the cap 12 is attached to the container part 11, scattering of the contents P when the contents P is poured out can be suppressed. The contents P in the storage space 16a are guided radially outward by the inclined surface of the bulging portion 30b that descends radially outward, and are collected on the side of the spout 33. Therefore, the contents P can be efficiently poured out from the spout 33.

[0047] FIG. 13 is a diagram showing how to use the cap 12. The user can bring an applicator such as the puff 13 or the brush 46 into contact with the contents P accumulated on the inner surface of the cap 12, thereby attaching the contents P to the applicator. 12, with the cap 12 removed and the spout 33 open, the user can shake and vibrate the container part 11 above the cap 12 to pour out the contents P from the spout 33 and add the contents P to the inner surface of the cap 12. The spout 33 is a single opening and does not have a large opening area like a mesh, so that scattering of the contents P when adding the contents P to the inner surface of the cap 12 can be suppressed.

[0048] When the removed cap 12 is reattached to the container portion 11, as the cap 12 is rotated in the direction opposite to the release direction R, friction between the female thread portion 42 and the thread portion 34 causes the inner lid member 15 to rotate in the direction opposite to the release direction R, and the stopper abutment portions 36a, 36b come into contact with the stopper portions 24d, 24e in the direction opposite to the release direction R, as shown in FIG. 7. This stops the inner lid member 15 from rotating in the direction opposite to the release direction R. If the cap 12 is further rotated in the direction opposite to the release direction R, the female thread portion 42 of the cap 12 screws into the thread portion 34, and the cap 12 is fastened to the thread portion 34.

[0049] As described above, according to an embodiment of the present invention, powder container 10 includes container body 14 that stores powdered contents P, container portion 11 that includes inner cover member 15 that closes opening 14a of container body 14, and cap 12 that screws onto threaded portion 34 on the outer periphery of container portion 11 to cover inner cover member 15, with inner cover member 15 having spout 33 for dispensing contents P. Powder container 10 is provided with vibration generating unit 45 that generates vibrations in response to relative rotation between cap 12 and container portion 11 when the cap and container portion are unscrewed. Vibration generating unit 45 includes a plurality of first protrusions 21 that are arranged circumferentially on the outer periphery of container body 14, and second protrusions 43a, 43b that are provided on the inner periphery of cap 12 and move circumferentially while climbing over first protrusions 21 due to the relative rotation. According to this configuration, when powder container 10 is in an inverted position with spout 33 facing downward and cap 12 is rotated in a direction to unscrew cap 12, second protrusions 43a and 43b move circumferentially while climbing over first protrusion 21, and vibration is generated by vibration generating unit 45. This vibration promotes the dispensing of contents P from spout 33, and contents P that fall from spout 33 accumulate in cap 12 as it rotates to unscrew the cap, and when cap 12 is removed from container unit 11, the contents accumulate within cap 12. In this way, when powder container 10 is in an inverted position and cap 12 is unscrewed and removed from container unit 11, contents P automatically accumulate within cap 12, making it easy to dispense and store contents P.

[0050] Furthermore, the inner lid member 15 is attached to the mouth portion 14a so as to be rotatable relative to the mouth portion 14a, and the container body 14 is provided with a lid portion 26 that covers and closes the pouring outlet 33 from the inside of the container body 14, and the above-mentioned relative rotation causes the inner lid member 15 to rotate integrally with the cap 12, and the pouring outlet 33 to move circumferentially relative to the lid portion 26, thereby opening the pouring outlet 33. According to this configuration, the spout 33 can be closed by the lid portion 26, thereby sealing the contents P. Furthermore, the spout 33 can be opened by moving it relative to the lid portion 26 by rotating the cap 12 when unscrewing it, so no special operation is required to open the spout 33, and the contents P can be easily poured and stored.

[0051] Furthermore, the threaded portion 34 is provided on the outer periphery of the inner lid member 15, and the opening portion 14a is provided with stopper portions 24d, 24e that restrict the rotation of the inner lid member 15. When the cap 12 is rotated in the release direction R from a closed state to release the threaded portion 34, the cap 12 and the inner lid member 15 rotate together, opening the spout 33. When the cap 12 is further rotated in the release direction R, the inner lid member 15 abuts against the stopper portions 24d, 24e, stopping the rotation of the inner lid member 15, and the cap 12 rotates in the release direction R. According to this configuration, after the rotation of the cap 12 is used to rotate the inner lid member 15 to open the spout 33, the rotation of the inner lid member 15 is stopped by the stopper portions 24d, 24e, and only the cap 12 can be easily removed.

[0052] Furthermore, the cap 12 has a female threaded portion 42 that screws into the threaded portion 34, and the upper end of the threaded portion 34 is provided with a protrusion 37 that protrudes radially outward and abuts against the top of the thread of the female threaded portion 42. According to this configuration, the protrusion 37 at the upper end of the threaded portion 34 of the inner lid member 15 abuts against the top of the thread of the female threaded portion 42 of the cap 12, thereby allowing the inner lid member 15 to be firmly screwed onto the cap 12. Therefore, when the cap 12 and the container portion 11 are unscrewed, the inner lid member 15 and the cap 12 can be rotated together.

[0053] Vibration generating section 45 is provided with one-side convex section group 21a and other-side convex section group 21b, which are vibration sections where vibration is generated by contact between first convex section 21 and second convex sections 43a, 43b, and circumferential sections 22a, 22b, which are non-vibration sections where vibration is not generated because first convex section 21 is not provided. Second convex sections 43a, 43b are located in the non-vibration section until cap 12 is rotated in release direction R from the closed state to open spout 33, and then transition to the vibration section when spout 33 is open. According to this configuration, vibration generating unit 45 does not generate vibration until cap 12 is rotated from the closed state in release direction R to open spout 33, so cap 12 and inner lid member 15 can be rotated smoothly to easily open spout 33. Furthermore, since vibration generating unit 45 generates vibration when spout 33 is open, the vibration allows content P to be efficiently poured out of spout 33.

[0054] In addition, the inner lid member 15 has a support piece 32 in the center thereof, which is a puff storage section capable of storing a puff 13 for applying the contents P, and the spout 33 is provided radially outward from the support piece 32. According to this configuration, even if the puff 13 can be stored in the inner lid member 15, the contents P can be poured from a radially outer position avoiding the puff 13, and the contents P can be stored in the cap 12.

[0055] In addition, the inner lid member 15 has a bulging portion 30b that bulges into the container body 14 so that the central portion of the inner lid member 15 is higher when the powder container 10 is inverted so that the cap 12 is positioned downward, and the pouring outlet 33 is located radially outward from the bulging portion 30b. According to this configuration, the bulging portion 30b, which bulges out so that the central portion is higher, allows the contents P to be collected at the outlet 33 on the radially outer side, and the contents P can be efficiently poured from the outlet 33 into the cap 12.

[0056] Although one embodiment of the present invention has been described above, the present invention is not limited to the specific embodiment, and unless otherwise limited in the above description, various modifications and variations are possible within the spirit and scope of the present invention as defined in the claims. For example, the configurations of the above-described embodiment may be added or deleted as appropriate, and the configurations of one embodiment may be incorporated into other embodiments. Furthermore, the effects of the above-described embodiment are merely examples of the effects resulting from the present invention, and do not mean that the effects of the present invention are limited to the above-described effects. In the above embodiment, the vibration generating unit 45 has been described as including the first protrusion 21 provided on the outer periphery of the container body 14 and the second protrusions 43a, 43b provided on the inner periphery of the cap 12, but the present invention is not limited to this. For example, the vibration generating unit may include a plurality of first protrusions provided circumferentially aligned on the inner periphery of the cap 12, and second protrusions provided on the outer periphery of the container body 14 that move circumferentially while climbing over the first protrusions due to relative rotation between the cap 12 and the container part 11. Furthermore, in the above embodiment, the threaded portion 34 is described as being provided on the outer periphery of the inner lid member 15, but the present invention is not limited to this. For example, a configuration may be adopted in which the threaded portion onto which the cap 12 is threaded is provided on the outer periphery of the container body 14, which is the outer periphery of the container portion, the mouth portion 14a is closed with an inner lid member having a spout, and the cap 12 is rotated relative to the threaded portion to generate vibrations by the vibration generating unit 45.
