[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 partial cross-sectional view showing a powder container 10 according to an embodiment of the present invention.

[0010] The powder container 10 comprises a container body 11 for storing contents P, an inner lid member 12 for closing the upper surface of the container body 11, a cover 13 for covering the inner lid member 12 from above, and a cap 14 for covering the cover 13 from above. The powder container 10 also includes a front chamber 15 formed between the cover 13 and the inner lid member 12 .

[0011] The container body 11 includes a container bottom wall 11a, a cylindrical body portion 11b extending upward from the periphery of the container bottom wall 11a, and a mouth portion 11c. The space surrounded by the container bottom wall 11a and the body portion 11b is a storage space 11d for storing the contents P. The contents P are powder, and are not particularly limited to, for example, cosmetics.

[0012] The mouth portion 11c is cylindrical and extends upward from the upper end of the body portion 11b. A cap engaging portion 11e is provided on the outer periphery of the mouth portion 11c, with which the cap 14 engages. The cap engaging portion 11e is a male thread portion formed on the outer periphery of the mouth portion 11c. 1, the powder container 10 is shown in an upright position, with the powder container 10 placed upright so that the axis 11f of the mouth portion 11c is oriented vertically. The axis 11f is the center line of the mouth portion 11c and is arranged coaxially with the axis of the body portion 11b.

[0013] Fig. 2 is a cross-sectional view showing the inner lid member 12 and the cover 13. Fig. 3 is a bottom view of the cover 13 as seen from the inside of the container body 11. The cross section of the cover 13 in Fig. 1 is cross section II in Fig. 3. 1 to 3, the cover 13 includes a cylindrical inner tubular portion 16 that fits into the inner peripheral surface of the mouth portion 11c, and a dome-shaped cover main body portion 17 that bulges upward from the upper end of the inner tubular portion 16. A locking portion 16a that protrudes radially inward is provided on the lower part of the inner circumferential surface of the inner cylindrical portion 16. The locking portion 16a is an annular protrusion that goes around the inner circumferential surface of the inner cylindrical portion 16.

[0014] The cover main body portion 17 comprises a curved dome portion 18 whose outer diameter decreases as it extends upward from the inner cylindrical portion 16, a discharge port 19 for discharging the contents P, a protrusion 20 that protrudes downward from the inner surface of the dome portion 18 toward the middle lid member 12, and an annular flange portion 21 that protrudes radially outward from the lower end of the dome portion 18. The center line of the cover main body 17 (the center line of the dome portion 18) is provided coaxially with the axis 11f.

[0015] Discharge port 19 is composed of a plurality of slit groups 19a (FIG. 3). Slit groups 19a are arranged at equal intervals in the circumferential direction on an imaginary circle centered on axis 11f. In this embodiment, slit groups 19a are arranged in four locations at 90° intervals in the circumferential direction of cover body portion 17. Each slit group 19a is composed of multiple slits 19b extending in the radial direction of the cover main body 17. The slits 19b are linear cuts that penetrate the dome portion 18 in the thickness direction. In this embodiment, each slit group 19a is composed of three slits 19b lined up in a direction perpendicular to the longitudinal direction of the slits 19b.

[0016] The dome portion 18 having the discharge port 19 also functions as an applicator that comes into contact with the object to be coated and applies the contents P. The dome portion 18 is subjected to a flocking process in which short fibers are attached to the surface of the dome portion 18.

[0017] The protrusion 20 is rod-shaped and extends parallel to the axis 11f. The protrusions 20 include a plurality of central protrusions 20a provided in the center of the dome portion 18, and a plurality of outer peripheral protrusions 20b arranged on the outer peripheral side of the dome portion 18 relative to the central protrusions 20a.

[0018] The central projection 20 a is disposed radially inward of the cover body 17 relative to the discharge port 19 . The center projections 20a are arranged at equal intervals in the circumferential direction on an imaginary circle centered on the axis 11f. In this embodiment, the center projections 20a are arranged at four locations at 90° intervals in the circumferential direction of the cover main body 17.

[0019] The outer peripheral projection 20b is disposed radially outward of the cover body 17 relative to the discharge port 19. The outer peripheral projections 20b are arranged at equal intervals in the circumferential direction on an imaginary circle centered on the axis 11f. In this embodiment, the outer peripheral projections 20b are arranged at eight locations at 45° intervals in the circumferential direction of the cover main body 17. In the up-down direction, the position of the lower end of the central projection 20a is the same as the position of the lower end of the outer peripheral projection 20b.

[0020] A receiving portion 18a is provided on the lower surface of the dome portion 18. The receiving portion 18a is annular and has its center on the axis 11f. The receiving portion 18a extends radially inward from the upper end of the inner cylindrical portion 16.

[0021] The inner cylindrical portion 16 is made of a synthetic resin that is harder than the cover main body portion 17. The cover main body portion 17 is made of a synthetic resin that is more elastic than the inner cylindrical portion 16, such as an elastomer. The cover 13 is configured by integrally molding an inner cylindrical portion 16 and a cover main body portion 17 by a molding method such as insert molding.

[0022] The cover 13 is fixed to the mouth portion 11c by fitting the inner cylindrical portion 16 to the inner peripheral surface of the mouth portion 11c and by abutting the flange portion 21 of the cover main body portion 17 against the upper surface of the mouth portion 11c.

[0023] The cap 14 includes a dome-shaped cap body 14a that fits along the upper surface of the dome portion 18, and a cylindrical engagement portion 14c that extends downward from the radially outer end of the lower surface 14b of the cap body 14a. Note that in Fig. 1, only the cross section of the right side of the cap 14 is shown, and the left side is not shown. The cap 14 is fixed to the mouth portion 11c by threading the female thread on the inner peripheral surface of the engagement portion 14c into the male thread on the outer periphery of the mouth portion 11c. The cap 14 also seals the space inside the cap 14 by compressing the flange portion 21 of the cover body 17 between the lower surface 14b and the upper surface of the mouth portion 11c.

[0024] The inner lid member 12 comprises an inner lid 30 that is placed inside the mouth portion 11c and closes the opening of the mouth portion 11c, a biasing member 31 that biases the inner lid 30 toward the cover 13, and an annular base portion 32 that is attached to the inside of the mouth portion 11c. More specifically, the inner lid member 12 is disposed inside the inner cylindrical portion 16 of the cover 13, and is attached to the opening portion 11c via the inner cylindrical portion 16. The inner lid member 12 is a part made of synthetic resin in which an inner lid 30, a biasing member 31, and a base portion 32 are integrally formed.

[0025] The inner lid 30 includes a disk-shaped lid plate 33 that fits along the inner circumferential surface of the opening 11c, and a rib 34 that is provided on the upper surface of the lid plate 33. The receiving portion 18a of the cover main body 17 is formed in an annular shape so as to fit along the peripheral edge 33a of the cover plate 33. The peripheral edge 33a of the cover plate 33 abuts against the receiving portion 18a from below. The outer diameter of the cover plate 33 is smaller than the inner diameter of the inner cylindrical portion 16 and the inner diameter of the locking portion 16a.

[0026] The rib 34 comprises a first rib 34a arranged radially outward from the center side protrusion 20a, a second rib 34b arranged radially outward from the first rib 34a and radially inward from the outer peripheral side protrusion 20b, and a third rib 34c arranged radially outward from the outer peripheral side protrusion 20b. The first rib 34a, the second rib 34b, and the third rib 34c are annular protrusions that are arranged on imaginary concentric circles centered on the axis 11f.

[0027] The base portion 32 is fitted onto the inner peripheral surface of the inner cylindrical portion 16 above the locking portion 16a. The biasing member 31 is configured by a plurality of elastic pieces 31 a that extend radially inward and upward from the base portion 32 and are connected to the lower surface of the inner lid 30 . A plurality of elastic pieces 31a are provided at intervals in the circumferential direction of the inner lid 30. In this embodiment, the inner lid 30 is arranged at four locations at 90° intervals in the circumferential direction of the inner lid 30. Furthermore, an inner lid opening 35 that penetrates the inner lid member 12 in the radial direction is formed in the inner lid member 12 between the inner lid 30 and the base portion 32 and between adjacent elastic pieces 31a.

[0028] 2, when assembling the inner lid member 12 to the cover 13, the inner lid member 12 is inserted into the opening of the inner cylindrical portion 16 from the inner lid 30 side. Then, the inner lid member 12 is pushed into the inner cylindrical portion 16 until the base portion 32 passes over the locking portion 16a. When the inner lid member 12 is assembled to the cover 13 as shown in Figure 1, the upper surface of the peripheral portion 33a of the inner lid 30 abuts against the receiving portion 18a of the cover main body portion 17 from below, and the elastic piece 31a is compressed by a predetermined amount between the inner lid 30 and the base portion 32. The base portion 32 is prevented from coming off in the axial direction by abutting against the locking portion 16a.

[0029] Fig. 4 is a cross-sectional view showing the state in which cover 13 is pressed straight down. Fig. 5 is a cross-sectional view showing the state in which cover 13 is pressed diagonally downward. Fig. 6 is an enlarged view showing the state of the periphery of inner lid member 12 when cover 13 is not pressed. Fig. 7 is an enlarged view showing the state of the periphery of inner lid member 12 when cover 13 is pressed. In Figures 4 and 5, the state of the inner lid member 12 when the cover 13 is pressed is shown in the right half of the figure, and the state of the inner lid member 12 when the cover 13 is not pressed is shown in the left half of the figure.

[0030] The powder container 10 is configured so that the amount of content P dispensed can be adjusted by pressing the cover 13 to move the inner lid 30. When the cover 13 is not pressed, as shown in Figure 6, the inner lid 30 is biased toward the upper receiving portion 18a by the biasing force of the elastic piece 31a, and the upper surface of the peripheral portion 33a abuts against the receiving portion 18a of the cover main body portion 17 from below. In addition, an annular outer gap 36 is formed between the inner lid 30 and the inner cylindrical portion 16 by radially separating the outer peripheral surface of the inner lid 30 from the inner peripheral surface of the inner cylindrical portion 16.

[0031] 4 and 5, when the cover 13 is pressed downward, such as directly downward or diagonally downward, the inner lid 30 is pushed downward by the protrusions 20, and as shown in FIG. 7, the upper surface of the peripheral portion 33a of the inner lid 30 moves downward away from the receiving portion 18a. In this state where the peripheral portion 33a is moved downward away from the receiving portion 18a, a gap is formed between the upper surface of the peripheral portion 33a and the receiving portion 18a. This gap serves as a passage 37 that connects the storage space 11d and the front chamber 15.

[0032] That is, when the cover 13 is not pressed, the inner lid 30 abuts against the receiving portion 18a to close the passage 37, as shown in Fig. 6. When the cover 13 is pressed, the inner lid 30 moves downward away from the receiving portion 18a to open the passage 37, as shown in Fig. 7. When the passage 37 is open, the contents P can move from the storage space 11d to the front chamber 15 through the passage 37 as shown by the arrow in Figure 7. The front chamber 15 is a space defined by the inner surface of the dome portion 18 and the upper surface of the inner lid 30.

[0033] Here, an example of how to use the powder container 10 will be described. As shown in FIG. 1, in the non-operated state where the cover 13 is not pressed, the passage 37 (FIG. 7) is closed by the inner lid 30, and the opening of the discharge port 19 formed by the slit 19b is also closed. In this non-operated state, the contents P cannot move from the storage space 11d to the front chamber 15. Furthermore, in the non-operated state, the mouth of the discharge port 19 is closed, so even if the contents P remain in the front chamber 15, the contents P will not be discharged from the discharge port 19. This prevents the contents P from spilling when, for example, the powder container 10 is moved. As shown in FIG. 1, when the cap 14 is attached, the pressing operation of the cover 13 is restricted by the cap 14.

[0034] FIG. 8 is a cross-sectional view showing a state in which the passage 37 is opened to discharge the contents P. When discharging the contents P, the cap 14 (FIG. 1) is removed, the powder container 10 is tilted so that the discharge port 19 faces downward, and the cover 13 is pressed. When cover 13 is pressed, dome portion 18 elastically deforms and bends toward inner lid 30. When cover 13 is pressed to a depth where protrusion 20 presses against the top surface of inner lid 30, inner lid 30 is pressed by protrusion 20, and passage 37 opens as shown in FIG.

[0035] 7 and 8, when the passage 37 is opened, the contents P move from the storage space 11d to the front chamber 15 through the inner lid opening 35, the outer peripheral gap 36, and the passage 37. Furthermore, when cover 13 is pressed, dome portion 18 elastically deforms, deforming slit 19b and opening the opening of discharge port 19 (opening of slit 19b). As a result, content P in front chamber 15 is discharged from discharge port 19 to the outside. In this way, when the cover 13 is pressed to the depth where the passage 37 opens, the contents P are supplied to the front chamber 15 through the passage 37, so that a relatively large amount of the contents P can be discharged from the discharge port 19. Furthermore, increasing the pressing depth of the cover 13 also increases the opening of the passage 37. Therefore, by adjusting the pressing depth of the cover 13 by the user, the amount of the contents P discharged can be adjusted. When the pressing operation of the cover 13 is released, the passage 37 is closed by the biasing force of the biasing member 31, and the cover 13 returns to its original shape due to its elasticity.

[0036] The cover 13 can be pressed, for example, by directly pressing the cover 13 against the application target of the contents P. In this case, the contents P can be applied by the cover 13 as an applicator while the cover 13 is pressed against the application target to eject the contents P. Therefore, the passage 37 can be opened by the same action as pressing the cover 13 to apply the contents P, making it easy to adjust the amount of content P ejected.

[0037] FIG. 9 is a cross-sectional view showing a state in which the content P is discharged with the passage 37 closed. In FIG. 9, the cover 13 is pressed to a shallower depth than in the state of FIG. Even when the cover 13 is pressed, if the pressing depth is such that the protrusion 20 does not reach the top surface of the inner lid 30 as shown in Figure 9, the passage 37 will be maintained in a closed state. Even in this case, the dome portion 18 is elastically deformed by the pressing operation, and the deformation of the slit 19b opens the opening of the discharge port 19. As a result, the contents P remaining in the front chamber 15 are discharged to the outside through the discharge port 19. In this way, when the cover 13 is pressed shallowly, the contents P are not supplied from the passage 37 to the front chamber 15, and the contents P remaining in the front chamber 15 are discharged from the discharge port 19. This makes it possible to reduce the amount of the contents P discharged.

[0038] For example, if you want to spread the contents P evenly, you can apply it by lightly pressing the cover 13 against the object to be applied, and with the passage 37 closed, the contents P in the front chamber 15 can be ejected from the opening of the slit 19b, allowing for good application.

[0039] As shown in FIG. 4, when the center of the cover 13 is pressed substantially parallel to the axis 11f, the center of the dome portion 18 is largely deflected, and the center-side protrusion 20a presses the upper surface of the inner lid 30 preferentially. When the tip of the center-side protrusion 20a slides radially outward on the top surface of the inner lid 30 due to the pressing operation, the tip of the center-side protrusion 20a abuts against the first rib 34a, preventing the center-side protrusion 20a from sliding beyond the first rib 34a. This allows the center-side protrusion 20a to press the inner lid 30 appropriately to open the passage 37.

[0040] As shown in FIG. 5, when a radially outer portion of the cover 13 is pressed or when the cover 13 is pressed obliquely with respect to the axis 11f, the outer peripheral projections 20b press the upper surface of the inner lid 30 preferentially. For example, if the tip of the outer peripheral projection 20b slides radially inward on the upper surface of the inner lid 30 as a result of a pressing operation in an oblique direction, the tip of the outer peripheral projection 20b abuts against the second rib 34b, preventing the outer peripheral projection 20b from sliding past the second rib 34b. Also, if the tip of the outer peripheral projection 20b slides radially outward on the upper surface of the inner lid 30 as a result of a pressing operation, the tip of the outer peripheral projection 20b abuts against the third rib 34c, preventing the outer peripheral projection 20b from sliding past the third rib 34c. Therefore, the outer peripheral projection 20b can press the inner lid 30 appropriately to open the passage 37.

[0041] As described above, according to an embodiment of the present invention, powder container 10 comprises container body 11 having storage space 11d for storing powdered contents P, inner lid 30 for closing opening 11c of container body 11, cover 13 for covering inner lid 30 from the outside and having discharge port 19 for discharging contents P to the outside, and front chamber 15 formed between cover 13 and inner lid 30. Inner lid 30 opens and closes passage 37 connecting storage space 11d and front chamber 15, and is provided with biasing member 31 for biasing inner lid 30 to close passage 37. When cover 13 is elastically deformed by a pressing operation, inner lid 30 is moved against the biasing force of biasing member 31, opening passage 37. According to this configuration, when cover 13 is elastically deformed by a pressing operation, cover 13 moves inner lid 30 against the biasing force of biasing member 31, opening passage 37 that connects storage space 11d and front chamber 15. Adjusting the amount of elastic deformation of cover 13 by a pressing operation adjusts the opening degree of passage 37, thereby adjusting the amount of contents P that move from storage space 11d to front chamber 15. The contents P that move to front chamber 15 can be discharged from discharge port 19 of cover 13. Therefore, the amount of contents P that are discharged can be adjusted according to the amount of pressing operation of cover 13, making it easy to adjust the amount of discharge. Furthermore, when cover 13 is not elastically deformed by a pressing operation, passage 37 is closed by inner lid 30, preventing contents P from moving from storage space 11d to front chamber 15, thereby preventing spillage of contents P.

[0042] Furthermore, the outlet 19 is a slit-like opening with a closed mouth when the cover 13 is not deformed, and opens when the cover 13 is elastically deformed by a pressing operation. According to this configuration, when the cover 13 is not deformed, the opening of the discharge port 19 is closed, thereby preventing spillage of the contents P. When the cover 13 is elastically deformed by pressing, the discharge port 19 opens, so that the discharge port 19 can be opened in conjunction with the passage 37 that is opened by pressing, and the amount of discharge from the discharge port 19 can be adjusted with a simple operation.

[0043] The cover 13 is formed in a dome shape and has a protrusion 20 that protrudes from the inner surface of the cover 13 toward the inner lid 30 , and presses the inner lid 30 via the protrusion 20 . According to this configuration, inner lid 30 is pressed via protrusion 20 protruding from the inner surface of dome-shaped cover 13, so that space can be secured around protrusion 20 within cover 13, thereby ensuring a large volume for front chamber 15 inside cover 13. In addition, because protrusion 20 is provided on a part of cover 13, there is a high degree of freedom in the placement of discharge port 19.

[0044] Furthermore, the protrusion 20 includes a central protrusion 20a provided in the center of the cover 13, and an outer peripheral protrusion 20b disposed on the outer peripheral side of the cover 13 relative to the central protrusion 20a. With this configuration, when the center of the cover 13 is pressed, the inner lid 30 can be pressed via the center-side protrusion 20a, and when the outer periphery of the cover 13 is pressed, the inner lid 30 can be pressed via the outer periphery-side protrusion 20b. This makes it possible to widen the range over which the cover 13 can be pressed, and to easily adjust the discharge amount.

[0045] In addition, a rib 34 is provided on the upper surface of the inner lid 30 to abut against the tip of the protrusion 20 and prevent the protrusion 20 from sliding on the inner lid 30. According to this configuration, when the cover 13 is pressed, the ribs 34 prevent the protrusions 20 from sliding on the inner lid 30, so the protrusions 20 can press the inner lid 30 appropriately to open the passage 37. In addition, the ribs 34 can increase the rigidity of the inner lid 30, so deformation of the inner lid 30 can be suppressed and the passage 37 can be effectively closed.

[0046] In addition, the cover 13 has an annular receiving portion 18a that fits along the peripheral portion 33a of the inner lid 30, and the passage 37 is a gap formed between the receiving portion 18a and the peripheral portion 33a of the inner lid 30, and is closed when the peripheral portion 33a abuts against the receiving portion 18a. According to this configuration, the passage 37 can be formed with a simple structure by the gap formed between the receiving portion 18a provided on the cover 13 and the peripheral portion 33a of the inner lid 30. In addition, the passage 37 can be closed with the simple structure of abutting the peripheral portion 33a of the inner lid 30 against the receiving portion 18a.

[0047] Furthermore, an inner lid member 12 is provided, which comprises a ring-shaped base portion 32 attached to the inside of the mouth portion 11c, a biasing member 31, and an inner lid 30, and the biasing member 31 is an elastic piece 31a extending upward from the base portion 32 and connected to the inner lid 30, and multiple pieces are provided at intervals around the circumferential direction of the inner lid 30. According to this configuration, the biasing member 31 and the inner lid 30 can be attached to the inside of the opening 11c with a simple structure via the base 32. Furthermore, the contents P can be passed toward the passage through the gaps between the multiple elastic pieces 31a provided at intervals in the circumferential direction of the inner lid 30, and the structure for biasing the inner lid 30 and the structure for passing the contents P can be provided in a compact manner.

[0048] 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 first rib 34a, the second rib 34b, and the third rib 34c are described as annular protrusions arranged on imaginary concentric circles centered on the axis 11f, but the present invention is not limited to this. The first rib 34a does not have to be connected annularly as long as it is provided at a position corresponding to the center-side protrusion 20a in the circumferential direction.
