[0003] [Patent Document 1] Patent Publication No. 2005-53502 Summary of the Invention [Problem to be solved by the invention]

[0004] In Patent Document 1, the nozzle is sealed with a sealant to prevent powder from entering the measuring chamber during sealing and transportation, enabling stable measuring from the first use. However, because the measuring mechanism is located above the nozzle, the container with the cap attached has the drawback of being bulky overall.

[0005] An object of the present invention is to provide a powder measuring cap that is not bulky when attached to a container and allows stable measuring. [Means for solving the problem]

[0006] The first means is a cap body 2 provided with a top plate 12 having a main vibration hole m1 for constant volume dispensing at the upper end of an attachment tube 4 that is fitted onto the outer surface of the nozzle 102 of the container body 100; A first cover portion 18A that can open and close the main swing hole m1; a cylindrical inner plug (20) with a bottom that is assembled to the cap body (2) and tightly fitted into the cylindrical mouth portion (102), The inside plug 20 has a bottom wall 26 that seals the entire cylindrical hole O of the nozzle portion 102, A partition plate 28 is erected from a boundary point d between the one half portion 26a and the other half portion 26b of the bottom wall 26 as viewed from the side Y, leaving an upper communication port CU between the top plate 12 and the partition plate 28. The half portion 26a is formed with a plug removal portion 30 having a removal means 32. The space between the bottom wall 26 and the top plate 12 is divided by the partition plate 28 into a continuous area B which is located above the one half portion 26a and which continues into the interior of the container body 100 when the unplugging portion 30 is removed, and a measuring and holding area A which is located above the other half portion 26b and which measures the powder introduced from the continuous area B side and holds the measured powder so that it can be discharged from the main ejection hole m1.

[0007] As shown in Figures 1(A) and 3(A), this means includes a bottomed, cylindrical inner plug 20 that is assembled to a cap body 2 that is fitted into the mouth portion 102 of a container body 100 and fits tightly into the mouth portion 102. The bottom wall 26 of the inside plug 20 seals the entire cylindrical hole O of the cylindrical mouth portion 102, and a partition plate 28 stands upright at the boundary d between one half 26a and the other half 26b of the bottom wall 26. The first half 26a is formed with an unplugging section 30, and the second half 26b is formed with a measuring and storage area A. A fixed amount of powder can be discharged from this area through the main ejection hole m1 of the cap body 2. This structure allows the container to be sealed during product distribution without being bulky, compared to a configuration in which the measuring mechanism is located above the nozzle 102 sealed with a sealant. Therefore, the contents of the container do not enter the measuring and storage area during distribution, ensuring stable quantitative delivery from the first use. Furthermore, since the sealing material can be omitted, there is no increase in costs.

[0008] The second means has the first means and includes an inclined wall portion t in which the one half portion 26a and the other half portion 26b each become higher as they approach the boundary point d, so that the bottom wall 26 has an approximately V-shape with the boundary point d as the apex when viewed from the side Y.

[0009] In this means, as shown in Figures 1(A) and 3(A), the one half 26a and the other half 26b each include an inclined wall portion t that becomes higher as it approaches the boundary point d, so that the bottom wall 26 has an approximately V-shape with the boundary point d as the vertex when viewed from the side Y. This structure allows the powder to move smoothly along the inclined wall portion t, making it possible to carry out the weighing operation smoothly, and also makes it easy to return the powder remaining in the continuous area B to the container body 100 side after the weighing operation.

[0010] The third means has the second means, and above the other half 26b, a partition wall portion 16 facing the partition plate 28 is suspended from the top plate 12, leaving a lower communication port CL between the other half 26b and the partition wall portion 16, and the main vibration hole m1 is positioned on the opposite side of the partition plate 28 from the partition wall portion 16.

[0011] In this means, as shown in Figures 1(A) and 3(A), above the other half 26b, a partition wall portion 16 facing the partition plate 28 is suspended from the top plate 12, leaving a lower communication port CL between it and the other half 26b, and the main vibration hole m1 is positioned on the opposite side of the partition plate 28 from the partition wall portion 16. With this structure, the partition wall 16 divides the measuring and storage area A into a measuring chamber a1 formed between the partition plate 28 and the partition wall 16 and a storage chamber a2 formed by the remaining space.

[0012] The fourth means has the first means or the second means, and the top plate 12 has the main hole m1 located above the other half portion 26b, and a secondary hole m2 for discharging any amount of fluid located above the one half portion 26a, and a second lid portion 18B is provided that can open and close this secondary hole m2.

[0013] In this embodiment, as shown in FIG. 3(A), the top plate 12 has the main hole m1 located above the other half portion 26b, and a secondary hole m2 for discharging a desired amount of fluid located above the one half portion 26a. This structure allows for convenient selection between fixed-volume dispensing operation and arbitrary-volume dispensing operation.

[0014] The fifth means includes any one of the first to third means, and the cap body (2) includes an inner cylindrical portion (10) that hangs down from the top plate (12) side inside the mounting cylinder (4), The inside plug 20 is formed by connecting the entire periphery of the bottom wall 26 to the inner surface of a plug barrel 22 attached to the cap body 2, and the plug barrel 22 is connected to the inner cylindrical portion 10 at its upper side. The aforementioned Mounting tube 4 The portion 4b located outside the inner cylindrical portion 10 is sandwiched between

[0015] In this means, as shown in FIG. 1(A) or FIG. 3(A), the cap body 2 has an inner cylindrical portion 10 that hangs down from the top plate 12 side inside the mounting cylinder 4. The inside plug 20 is formed by connecting the entire circumference of the bottom wall 26 to the inner surface of the plug barrel 22 attached to the cap body 2, and the plug barrel 22 is connected to the inner cylindrical portion 10 and the attachment barrel 4 at its upper side. The portion 4b located outside the inner cylindrical portion 10 is sandwiched between This structure ensures that the inner plug 20 is securely attached to the cap body 2, preventing the inner plug 20 from accidentally falling off. [Effects of the Invention]

[0016] According to the present invention, when assembled to a container body, the device is not bulky and allows stable weighing. [Brief explanation of the drawings]

[Figure 2] 2A and 2B are explanatory diagrams of the powder measuring cap shown in FIG. 1 in use, where FIG. 2A is a plan view of the main opening in an open state, and FIG. 2B is a cross-sectional view of the same state as seen from the side. [Figure 3] 3A shows the structure of a powder measuring cap according to a second embodiment of the present invention, in which (A) is a cross-sectional view seen from the side (second direction Y shown in FIG. 3B), and (B) is a bottom view. [Figure 4] 4A and 4B are explanatory diagrams of the powder measuring cap shown in FIG. 3 in use, in which FIG. 4A is a plan view of the secondary ejection hole in an open state, and FIG. 4B is a cross-sectional view of the same state as seen from the side. BEST MODE FOR CARRYING OUT THE INVENTION

[0018] 1 and 2 show a powder measuring cap 1 according to a first embodiment of the present invention. This powder measuring cap is used by being attached to the nozzle 102 of a container body 100 as shown in FIG. 2(B). The powder measuring cap 1 is formed of a cap body 2, a first lid portion 18A, and an inner plug 20, as shown in FIG. 1(A). Each of these members can be made of, for example, a synthetic resin material.

[0019] 1(A), the cap body 2 is formed by an attachment tube 4 that fits onto the nozzle 102 of the container body 100, and a top plate 12 attached to the upper end of the attachment tube. A main swing hole m1, which will be described later, is opened in the top plate 12.

[0020] In this embodiment, the mounting cylinder 4 is formed of a lower cylinder portion 4a with a large inner diameter, an intermediate cylinder portion 4b with a medium inner diameter, and an upper cylinder portion 4c with a small inner diameter. In the illustrated example, a female thread portion 6 is formed on the inner surface of the lower tubular portion 4a to be screwed onto the outer surface of the mouth tubular portion 102. However, the female thread portion 6 may be omitted and the attachment tube 4 may be fitted onto the outer surface of the mouth tubular portion 102. In the illustrated example, an inner cylindrical portion 10 hangs down from the underside of the upper cylindrical portion 4c with a gap between it and the intermediate cylindrical portion 4b, and the upper cylindrical portion 22c described below is arranged to be insertable between the inner cylindrical portion 10 and the intermediate cylindrical portion 4b. The structure of the inner cylindrical portion 10 can be modified as appropriate. For example, instead of being suspended from the underside of the upper cylindrical portion 4c, it may be suspended from the top plate 12. In this specification, when the inner cylindrical portion 10 is "suspended from the top plate side," it includes both of these modes. In the illustrated example, a notch 11 is formed at the lower end of the inner cylindrical portion 10 for engaging with an engaging element 24 described below. Further, a recessed portion 8 that is shallowly recessed radially inward is formed in a part of the outer peripheral surface of the mounting cylinder 4, close to a first recessed portion 14 described later.

[0021] The top plate 12 has a main vibration hole m1 for constant volume dispensing opened therein, positioned above a storage chamber a2 to be described later. The "main" in the term "main aperture" means that it is used for constant volume dispensing, which is the main operation of the cap of the present invention. In this embodiment, a plurality of (three in the illustrated example) main oscillation holes m1 are arranged in the top plate 12, offset to one side in the first direction X shown in FIG. 1(B). In the illustrated example, these main oscillation holes m1 are linearly arranged in the second direction Y shown in Fig. 1(B). However, the number and arrangement of the main oscillation holes m1 can be changed as appropriate. In the illustrated example, one side portion of the top plate 12 in the first direction X (in the illustrated example, the arch-shaped portion surrounded by the linear edge portion k and the arc-shaped edge portion j shown in Figure 2(A)) is flatly depressed to form a first depressed portion 14, and the multiple main vibration holes m1 are formed in this first depressed portion 14. These main ejection holes m1 are connected to a storage chamber a2 of the measuring and storage area A described later in order to discharge a fixed amount of powder.

[0022] As shown in FIG. 1(A), a partition wall portion 16 hangs down from the top plate 12, positioned above the other half portion 26b of a bottom wall 26, which will be described later. When viewed from below, the partition wall portion 16 extends long in the second direction Y as indicated by the dotted line in FIG. 1(B), and both ends of the partition wall portion 16 are connected to the inner cylindrical portion 10. When viewed from below, the partition wall portion 16 is disposed between a plurality of main oscillation holes m1 arranged in the second direction Y and a partition plate 28, which will be described later. The partition plate 28 and the partition wall portion 16 extend parallel to each other (parallel in the illustrated example). Note that "parallel" merely means that they extend in approximately the same direction as a whole. 1(A), the partition wall portion 16 hangs down longer than the inner cylindrical portion 10. A lower communication port CL is formed between the lower end of the partition wall portion 16 and the other half portion 26b.

[0023] The first lid portion 18A has the role of opening and closing the main swing-out hole m1, and is connected via a hinge 19 to an appropriate position of the first recessed portion 14 (the linear edge portion k in the illustrated example). Further, positioned on the opposite side to the hinge 19, a finger hook f is attached to the tip of the first cover portion 18A. A blocking projection n that seals the main swing hole m1 is provided downward from the underside of the first lid portion 18A in the illustrated example. In this embodiment, the first lid portion 18A is molded integrally with the cap body 2, but it may be provided as a separate body.

[0024] The inside plug 20 is a cylindrical member with a bottom that is assembled to the cap body 2 and fits tightly into the cylindrical mouth portion 102 . As shown in FIG. 1(A), the inside plug 20 is formed of a plug barrel 22 and a bottom wall 26.

[0025] The stopper cylinder 22 is a part for tightly fitting into the nozzle portion 102, as shown in FIG. 2(B). The bottom wall 26 is integrally and seamlessly connected to the inner surface of the plug barrel 22. "Without any gaps" means that the sealing function of the inside plug 20 is ensured. The plug barrel 22 in the illustrated example has an upper cylindrical portion 22c standing upright from the upper end of a lower cylindrical portion 22a via an outward flange 22b, although this structure can be modified as appropriate. The lower cylindrical portion 22a is fitted to the inner surface of the nozzle portion 102, thereby sealing the cylindrical hole O of the nozzle portion 102. The outward flange 22 b is placed on the upper end surface of the nozzle portion 102 . As shown in FIG. 1(A), the upper cylindrical portion 22c is Intermediate cylinder part 4b and the inner cylindrical portion 10. The upper side of the stopper cylinder 20 (in the illustrated example, the upper cylindrical portion 22c and the outward flange 22b) of the attachment cylinder 4 Intermediate cylinder part 4b and the inner cylindrical portion 10. This ensures that the inner plug 20 is securely attached to the cap body 2, preventing the inner plug 20 from accidentally falling off. In the illustrated example, a pressure-contact rib r that presses against the inner surface of the mounting tube 4 is provided on the outer surface of the outward flange 22c. An engaging piece 24 is attached to a part of the circumferential direction of the inner cylindrical portion 10, connected to the front surface of the outward flange 22b and the inner surface of the upper cylindrical portion 22c, and fitted into the notch 11. The engaging piece 24 and the notch 11 form a positioning means I that regulates the rotational position of the inside plug 20 relative to the cap body 2. By providing this positioning means I, it becomes easy to determine the rotational position of the inside plug 20 so that a partition plate 28 (described later) is parallel to the partition wall portion 16, as shown by the dotted line in FIG. 1(B).

[0026] The bottom wall 26 has the function of sealing the entire cylindrical hole O of the cylindrical mouth portion 102 in the initial state shown in FIG. 1(A) (the state before the unplugging portion 30 described below is removed). "Sealing the entire cylindrical bore" means sealing the entire flow passage area. In other words, the bottom wall 26 replaces the sealing material of Patent Document 1 and ensures that powder is prevented from entering the measuring chamber during sealing and transportation. Therefore, compared to the conventional technology in which a sealing material is adhered to the upper end surface of the nozzle portion 102, the height of the container body 100 equipped with the powder measuring cap 1 is reduced by the height difference h shown in Figure 2 (B) (the height difference between the upper end surface of the nozzle portion 102 and the bottom wall 26), making it possible to prevent it from becoming bulky. Further, a partition plate 28, which will be described later, stands upright from a boundary portion d between the one half portion 26a and the other half portion 26b of the bottom wall 26 when viewed from the side (second direction Y).

[0027] As shown in FIG. 1(B), the half portion 26a is formed with a plug removal portion 30 surrounded by a break line 31, which is a thin weakened line. The unplugging section 30 can be opened by pulling with a pulling means 32, which will be described later, and is configured so as not to impair the sealing function of the bottom wall 26 before this operation. In this embodiment, the unplug portion 30 is formed in the first direction X from one end (a lower end e1 described below) of the half portion 26a to the other end (a higher end e2 described below). However, this arrangement can be changed as appropriate, and it is sufficient that the unplugging portion 30 is formed at least on the lower end e1 side of the one half portion 26a. The illustrated unplugging portion 30 is formed in a generally diamond shape with rounded corners as shown in FIG. 1(B), but the shape can be modified as appropriate. The uncork section 30 is provided with a pull ring as a pull means 32 of the uncork section. However, the form of the pull means 32 can be changed as appropriate. By pulling the pull-out means 32 to remove the unplugging part 30, a through hole P is formed at the location where the unplugging part 30 is formed, as shown in FIG. 2(B). In this embodiment, as shown in Fig. 1(A), the pulling means 32 is provided so as to protrude downward from the unplugging part 30. The unplugging part 30 is configured so as to be removed by pulling downward as shown by the arrow in the figure.

[0028] The partition plate 28 extends in the second direction Y as shown by the dotted line in FIG. 1(B) when viewed from below, and both longitudinal ends of the partition plate 28 are connected to the stopper cylinder 22. As shown in FIG. 1(A), an upper communication port CU is formed between the partition plate 28 and the top plate 12. In addition, the partition plate 28 is formed to face at least a portion of the height direction of the partition wall portion 16 (the middle portion in the illustrated example), and a measuring chamber a1, which will be described later, is formed between the partition plate 28 and the partition wall portion 16. The role of the partition plate 28 is to divide the space between the bottom wall 26 and the top plate 12 into a continuous area B located on the one half portion 26a and a measuring and holding area A located on the other half portion 26b. The continuous region B is a region formed so as to be continuous with the inside of the container body 100 when the unplugging part 30 is removed while the container body 100 is attached. The measuring and retaining area A is an area for measuring the powder introduced from the continuous area B side through the upper communication port CU and for retaining the measured powder. As shown in FIG. 1(A), the measuring and storing area A is composed of a measuring chamber a1 and a storing chamber a2. As shown in FIG. 2(B), the measuring chamber a1 is a space extending between the partition plate 28 and the partition wall portion 16, and communicates with the continuous area B via the upper communication port CU. With this configuration, after removing the uncorking portion 30, the container body 100 with the powder measuring cap 1 attached is turned upside down, so that the powder that has entered the continuous area B from the through hole P can flow into the measuring chamber a1 through the upper communication port CU. The storage chamber a2 is a space extending between the partition wall 16 and the portions of the stopper tube 22 and the inner tube 10 that are on the opposite side of the partition plate 28 from the partition wall 16. The storage chamber a2 is in communication with the measuring chamber a1 via the lower communication port CL. With this configuration, when the container body 100 is returned from an upside-down state to an upright state, a certain amount of powder measured in the measuring chamber a1 can flow into the storage chamber a2 through the lower communication port CL. Moreover, the main swing-out hole m1 is opened above the storage chamber a2.

[0029] In this embodiment, as shown in FIG. 1(A), the bottom wall 26 is formed in a substantially inverted V shape with the boundary point d as the vertex when viewed from the second direction Y. The "substantially inverted V-shape" includes a tapered shape with an obtuse apex angle and a V-shape. The one half portion 26a and the other half portion 26b are formed into an inclined wall portion t that becomes higher as it approaches the boundary portion d when viewed from the side (the second direction Y). These inclined wall portions t have the role of guiding the powder to a lower position, as will be described later. In the illustrated example, the unplug portion 30 is formed from the lower end e1 to the higher end e2 of the half portion 26a, which is an inclined wall portion. Here, the "low end" refers to the lowest point among the peripheral edges of the one half, and the "high end" refers to the highest point among the peripheral edges of the one half. By tilting the other half 26b, when the container body 100 is returned from the upside-down state to the upright state as described above, the powder is smoothly guided from the measuring chamber a1 side to the storage chamber a2 side. Furthermore, by tilting the half portion 26a, the powder remaining in the continuous region B after the measuring operation can be guided to the through-hole P side and recovered to the container body 100 side through the through-hole. However, the structure of the first half portion 26a and the second half portion 26b can be changed as appropriate, and as long as the function of guiding the powder can be performed as described above, the entirety of each half portion does not need to be an inclined wall portion.

[0030] In the above configuration, as shown by the imaginary lines in Figure 1(A), when the inner stopper 20 of the powder measuring cap 1 is inserted into the nozzle 102 of the container body 100, the bottom wall 26 of the inner stopper 20 seals the nozzle hole O of the nozzle 102, thereby preventing powder from entering the measuring chamber a1 during product distribution. In this state, the bottom wall 26 penetrates from the upper end surface of the nozzle 102 to a depth of the height difference h, as shown in Figure 2(B). This reduces the overall volume of the container with the powder measuring cap compared to the prior art configuration in which the nozzle 102 is sealed with a sealing material. When using a container with a powder measuring cap for the first time, first remove the powder measuring cap 1 from the nozzle 102 of the container body 100, and then pull the pull-out means 32 downward as shown by the arrow in FIG. 1(A). As a result, the plug removal portion 30 is removed from the half portion 26a of the bottom wall 26, and the through hole P is opened as shown in FIG. 2(B). Next, the powder measuring cap 1 is attached to the nozzle 102 of the container body 100, and the container body 100 is turned upside down. The powder in the container body 100 falls through the through hole P into the continuous area B, and then enters the measuring chamber a1 from the continuous area B through the upper communication port CU. Since the measuring chamber a1 is a space defined between the partition plate 28 and the partition wall 16, the inflow of powder stops when a certain amount of powder enters the measuring chamber a1, thereby enabling the powder to be measured. When the container body 100 is returned to the upright position in this state, a certain amount of powder in the measuring chamber a1 slides down the other half portion 26b, which is the inclined wall portion, and enters the storage chamber a2 from the measuring chamber a1 through the lower communication port CL. At the same time, the powder in the continuous region B falls toward the half portion 26a. Some of the powder enters the through-hole P directly, while the remaining portion slides along the inclined wall of the half portion 26a, gathers on the lower end e1 side, and then flows into the through-hole P. As a result, most of the powder remaining in the continuous region B is collected into the container body 100 side. Next, the first lid portion 18A is opened to open the main shaking hole m1, and the container body 100 is tilted and shaken so that the main shaking hole m1 is on the bottom side, and a certain amount of powder in the storage chamber can be shaken out through the main shaking hole m1 to the outside. Next, the container body 100 is turned upright and the first lid portion 18A is closed, thereby returning it to its original state.

[0031] According to the above-described configuration and operation, by erecting a partition plate 28 from the boundary point d between one half 26a and the other half 26b of the bottom wall 26 of the inside plug 20 that fits tightly into the mouth portion 102 of the container body 100, the space above the other half 26b is made into a measuring and storage area A, and an extractor section 30 is formed in the one half 26a. Until the extractor section 30 is removed, the bottom wall 26 inserted into the mouth portion 102 seals the bore O of the mouth portion, so that the contents do not enter the measuring chamber a1 during product distribution, and the container body equipped with the powder measuring cap is not bulky. The bottom wall 26 has an inverted V-shape with the boundary point d as the vertex, which allows the powder to move smoothly along the bottom wall 26, and makes it easy to recover the powder remaining in the continuous area B to the container body 100 side after the measuring operation. Furthermore, since the upper side of the stopper cylinder 22 is clamped between the mounting cylinder 4 and the inner cylinder portion 10 of the cap body 2, it is possible to prevent the inner stopper 20 from accidentally falling off.

[0032] Other embodiments of the present invention will be described below, and in these descriptions, explanations of structures that are the same as those in the first embodiment will be omitted.

[0033] 3 and 4 show a powder measuring cap according to a second embodiment of the present invention. This embodiment differs from the first embodiment in that the configuration of the drawing means 32 and the half portion 26a is modified, and the second lid portion 18B and the secondary injection hole m2 are added.

[0034] In this embodiment, the pulling means 32 is provided to protrude upward from the uncork part 30. In this embodiment, while the powder measuring cap 1 is attached to the container body 100, the uncork part 30 can be removed by inserting a finger through the secondary shake-out hole m2, hooking the finger on the pulling means 32, and pulling it up, as described below. Therefore, when removing the uncorking part 30, the work of removing the powder measuring cap 1 from the nozzle part 102 of the container body 100, as in the first embodiment, can be omitted.

[0035] In the first embodiment, the one half portion 26a was formed as a single inclined wall portion t as a whole, but in this embodiment, the one half portion 26a is formed by a flat wall portion s that is adjacent to the partition plate 28 and has a narrow strip shape when viewed from above, and an inclined wall portion t that is connected to this flat wall portion s and has an approximately semicircular shape when viewed from above. The flat wall portion s is a portion at least the upper surface of which is flat.

[0036] The secondary ejection hole m2 is connected to the continuous region B in order to eject a desired amount of powder, and is opened at a location on the top plate 12 above the one half portion 26a. The "secondary" in the secondary ejection hole means that it is used for discharging any amount of liquid, which is a secondary operation of the cap of the present invention. The shape (opening area and number) of the secondary hole m2 is preferably different from that of the main hole m1. In the illustrated example, the secondary hole m2 is a single hole, and its opening area is larger than the sum of the opening areas of the multiple main holes m1. The secondary opening m2 is formed in a second recess 15 formed on the upper surface of the top plate 12, positioned above the one half portion 26a. The shape and size of the secondary swing-out hole m2 are designed so that the drawing means 32 and the unplugging part 30 can be pulled out upward through the secondary swing-out hole m2. The secondary hole m2 in the illustrated example is a wide-mouthed, approximately semicircular hole that opens in the right half of the top plate 12 in the first direction X, leaving a small peripheral portion of the right half open, as shown by the dotted line in Figure 3(B). A second cover portion 18B for opening and closing the secondary swing-out hole m2 is connected to the top plate 12 via a hinge 19. The hinges 19 of the first cover portion 18A and the second cover portion 18B are disposed closer to the inside in the first direction X, as shown in FIG. 4(A). The description of the first lid portion 18A in the first embodiment applies to the second lid portion 18B, and the description of the first recessed portion 14 applies to the second recessed portion 15.

[0037] According to the above configuration, when a desired amount of powder is to be initially ejected, the second lid portion 18B is opened, and the user inserts his / her finger through the secondary ejection hole m2, hooks it onto the pulling means 32, and pulls it up to remove the unplugging portion 30 from the first half portion 26a. Thereafter, the container body 100 is tilted so that the secondary dispensing hole m2 faces downward, and the container body is shaken until the required amount of powder is dispensed. Furthermore, when it is desired to discharge a fixed amount of powder, the powder may be discharged from the main aperture m1 in the same manner as described in the first embodiment.

[0038] According to the above-described configuration and operation, the top plate 12 has the main hole m1 located above the other half 26b, and the secondary hole m2 for discharging any amount located above the one half 26a, so that fixed amount discharging operation and any amount discharging operation can be selected appropriately, making it easy to use. The pulling means 32 protrudes upward from the uncork portion 30, so that the uncork portion 30 can be easily removed from one half 26a of the bottom wall 26 by opening the second lid portion 18B, hooking a finger inserted through the secondary ejection hole m2 onto the pulling means 32, and pulling the pulling means 32 upward.
