Description

[Technical Field]

[0001] The present invention relates to a powder measuring device that stores powder as a stored item, measures a predetermined amount, and dispenses it. [Background technology]

[0002] Conventionally, there are measuring containers that store contents, measure a predetermined amount, and remove the contents. For example, Patent Document 1 discloses a tablet measuring container for storing tablets, which includes a container body that stores the tablets, an inner stopper attached to the container opening, and a transparent cover member that closes the upper opening of the inner stopper. The inner stopper has a bottom plate portion, and a measuring chamber is formed by the bottom plate portion of the inner stopper and the cover member, and the inner stopper has a measuring chamber inlet that communicates with the inside of the container body. The cover portion is attached to the inner stopper so as to be rotatable around the central axis, and the cover member has an outlet that communicates with the measuring chamber and a jump-out prevention portion that closes the measuring chamber inlet of the inner stopper. When the jump-out prevention portion of the cover member does not coincide with the measuring chamber inlet, the measuring chamber inlet communicates with the container body and is in a measuring state, and tablets pass through the measuring chamber inlet and are taken into the measuring chamber. When the jump-out prevention portion of the cover member coincides with the measuring chamber inlet, the outlet communicates with the measuring chamber, allowing tablets in the measuring chamber to be taken out.

[0003] The outlet device disclosed in Patent Document 2 is for containing a liquid and includes a bottle for containing the liquid, a fitting portion that fits into the opening of the bottle, a spout consisting of a cylindrical outer wall portion connected to the fitting portion, a top plate that covers the spout, a lid portion that swings to open and close a portion of the top plate, and a partition wall that divides the interior surrounded by the outer wall into upper and lower sections. The space inside the partition wall and the outer wall portion is a storage section for temporarily storing the contents. The partition wall is provided with a communication port that communicates with the interior of the bottle and a tubular communication port that surrounds the communication port and protrudes upward. The lid portion is provided with a swinging member that swings in conjunction with the swinging of the lid, and a stopper that is attached to the swinging member and closes the communication port when the lid is opened and opens the communication port when the lid is closed.

[0004] Another example is a powder measuring device that holds powder, granules, and other granular materials and measures and dispenses the desired amount. Patent Document 3 discloses a metered-volume dispenser for granular materials. One end of the seal cap that closes the mouth of a bottle containing the granular material has a notched discharge port, and two parallel, opposing partition pieces are attached to both edges of the discharge port. A flat, flat lid that seals the discharge port has a bent, movable scraping spatula that is always sandwiched between the two partition pieces and scrapes out the granular material when the lid is opened. To remove the granular material, the bottle is inverted with the flat lid closed over the discharge port, and the granular material is transferred to the mouth. When the flat lid is opened, the movable spatula rotates to scrape out the granular material. After the lid is fully discharged, the movable spatula closes the discharge port. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-88937 [Patent Document 2] Japanese Utility Model Application Publication No. 5-3147 [Patent Document 3] Utility Model Registration No. 3125245 Summary of the Invention [Problem to be solved by the invention]

[0006] The above-mentioned Patent Documents 1 and 2 do not consider weighing and dispensing powders, granules, etc. In the case of Patent Document 3, the movable spatula remains open toward the inside of the bottle for a long time from when the small-mouth flat lid opens from the discharge outlet until it is closed with the movable spatula, and there are no sliding surfaces that face each other closely and closely at any position as the movable spatula rotates. As a result, the movable spatula cannot separate the inside of the bottle from the movable spatula while rotating, allowing the powder or granules to fall, making it difficult to accurately weigh and dispense the powder or granules.

[0015] An embodiment of the present invention will now be described with reference to the drawings. Figures 1 to 6 show one embodiment of the present invention, in which a powder measuring container 10 of this embodiment has a cylindrical container body 12 with a bottom for containing powder 11, and the container body 12 is made of glass or plastic. The container body 12 has a cylindrical side surface 14, which is open at the top when upright, and is integrally formed with a cylindrical container opening 16 having a small diameter. A male thread 18 is formed on the outer circumferential surface of the container opening 16, into which a cap 62, described below, is screwed.

[0016] An inside plug 20 is attached to the opening edge 16a of the container opening 16. Inside plug 20 is provided with a cylindrical mounting portion 22 that is inserted into and fitted onto opening edge 16a, and a flange portion 26 that abuts against opening edge 16a and projects outward from the outer circumferential surface of mounting portion 22 and runs all the way around is provided at the upper end of mounting portion 22. A disk-shaped bottom plate portion 24 that closes mounting portion 22 is provided on the inner periphery of flange portion 26.

[0017] A cylindrical portion 28, consisting of four walls, is provided at the center of the top surface of the bottom plate portion 24. The cylindrical portion 28, when attached to the container body 12, stands at a predetermined height inward and outward from the container opening 16. The cross-sectional shape of the cylindrical portion 28, parallel to the bottom plate portion 24, is a generally rectangular shape that is long in one direction. The cross-sectional shape is formed by a pair of short arcs that run slightly inside the flange portion 26, which is the circumferential portion of the bottom plate portion 24, and a pair of long, parallel straight lines that connect the ends of the arcs. The long straight lines are positioned at equal intervals on both sides of the center of the bottom plate portion 24 and are parallel to the diameter. The arc portions face each other across the center of the bottom plate portion 24, each approximately one-sixth the length of the circumference of the flange portion 26. The opposite side of the cylindrical portion 28 from the bottom plate portion 24 defines an upper opening 30 that opens upward.

[0018] One of the pair of arcs of the tubular portion 28 extending from the bottom plate 24 is an outlet side portion 28a that faces an outlet side wall 50 in which an outlet 51 of the cover member 46 (described later) is provided. The outlet side portion 28a extends from the bottom plate 24 at a height substantially equal to the length of the attachment portion 22 in the insertion direction. The outer surface of the outlet side portion 28a is substantially perpendicular to the bottom plate 24 in the up-down direction. The thickness of the outlet side portion 28a in the diameter direction of the bottom plate 24 gradually increases toward the bottom plate 24, and the inner circumferential surface forms an outlet-side sliding curved surface 34 that is a curved surface that approaches the center of the bottom plate 24 as it approaches the bottom plate 24. The outlet-side sliding curved surface 34 is shaped to follow the rotational path of the outlet side wall 50 of the cover member 46 (described later). The outlet side portion 28a has a projection receiving recess 43 at the edge of the upper opening 30 opposite the bottom plate portion 24, into which a closing projection 53 of a cover member 46, which will be described later, is inserted.

[0019] The other of the pair of arcs of the tubular portion 28 standing upright from the bottom plate portion 24 is a pressing portion side portion 28b that faces a pressing portion side wall 52, on which a pressing portion 55 is provided, located opposite the outlet side wall 50 of the cover member 46 described below. The height of the pressing portion side portion 28b is formed lower than the outlet side portion 28a, forming a side opening 32 in which the edge of the upper opening 30 is open, and does not interfere with the opening of the cover member 46 by pressing down the pressing portion 55 of the cover member 46 described below. The outer surface of the pressing portion side portion 28b is also approximately perpendicular to the bottom plate portion 24 in the vertical direction, and the thickness of the pressing portion side portion 28b in the diameter direction of the bottom plate portion 24 increases as it approaches the bottom plate portion 24, and the inner surface is formed with a pressing portion-side sliding curved surface 36, which is a curved surface that approaches the center of the bottom plate portion 24 as it approaches the bottom plate portion 24. The pressing portion-side sliding curved surface 36 has a shape that follows the rotational path of a pressing portion side wall 52 of the cover member 46, which will be described later.

[0020] The flat portions of the cylindrical portion 28 extending upright from the bottom plate portion 24 are a pair of side surface portions 28c, which have the same height as the outlet side portion 28a and a constant thickness. A bearing recess 42 is formed in each of the pair of side surface portions 28c at the edge of the upper opening 30. The bearing recess 42 is a semi-cylindrical cutout into which a rotating shaft 56 of a cover member 46 (described later) is rotatably inserted, and an opening slightly smaller in diameter than the bearing recess 42 is formed at the upper end. The pair of bearing recesses 42 are provided at positions facing each other on the pair of side surface portions 28c.

[0021] An inlet 38 penetrating the bottom plate 24 is provided in the inner half of the bottom plate 24, surrounded by the cylindrical portion 28, on the pressing portion side 28b side. The side edge of the inlet 38, away from the pressing portion side 28b, is a straight line approximately perpendicular to the pair of side surfaces 28c of the cylindrical portion 28, and a blocking portion 40 is integrally provided on this side edge. The blocking portion 40 is a rectangular plate that is continuous with the pair of side surfaces 28c. The base end is continuous with the straight side edge that is away from the pressing portion side 28b. The tip 40a is located approximately halfway along the inlet 38, close to the pressing portion side 28b, and slightly closer to the upper opening 30 than the bottom plate 24, and is formed at an angle relative to the bottom plate 24. The tip 40a is bent slightly toward the boundary between the pressing portion side 28b and the bottom plate 24, with a slightly smaller width.

[0022] A locking rib 44 is provided on the outer surface of one of the side portions 28c, protruding laterally from the side portion 28c. The locking rib 44 is a long protrusion that is elongated in one direction and is approximately perpendicular to the bottom plate portion 24 in its longitudinal direction. One end of the locking rib 44 is continuous with the bottom plate portion 24, and the other end reaches slightly below the bearing recess 42, and is located at a position slightly moved toward the outlet side portion 28a rather than directly below the center of the bearing recess 42.

[0023] A cover member 46 that closes the upper opening 30 of the cylindrical portion 28 is provided at the upper opening 30. The cover member 46 is provided with a top plate 48 that closes the upper opening 30, and the top plate 48 is a generally rectangular plate that is long in one direction and fits inside the cylindrical portion 28, and is formed by a pair of short arc-shaped end portions 48a, 48b that face the outlet side portion 28a and the pressing portion side portion 28b, and a pair of straight side edge portions 48c that connect both ends of the arcs and face the pair of side portions 28c.

[0024] An outlet side wall 50 that intersects with the top plate 48 is provided on the arcuate end 48a of the top plate 48. The outlet side wall 50 is overlapped on the inside of the outlet side portion 28a of the tubular portion 28 when the cover member 46 is closed on the upper opening 30 of the tubular portion 28 at approximately right angles to the insertion direction, and the outer surface of the outlet side wall 50 moves away from the arcuate end 48a as it approaches the protruding tip, while the inner surface is approximately perpendicular to the bottom plate portion 24, and the thickness of the outlet side wall 50 gradually decreases as it approaches the edge. The vertical length of the outlet side wall 50 is shorter than the vertical length of the outlet side portion 28a, and when attached to the upper opening 30 of the tubular portion 28, the outlet side wall 50 protrudes downward and is located near the bottom plate portion 24 but does not reach the bottom plate portion 24.

[0025] An outlet 51 for removing the contained powder 11 is provided in the center of the outlet side wall 50, penetrating the outlet side wall 50. The outlet 51 has a spherical curved surface that bulges upward, and its upper end is in contact with the top plate 48. The outer surface of the outlet side wall 50 is formed as a sliding curved surface that fits along the outlet-side sliding curved surface 34 with a small clearance. Because the outlet side wall 50 is provided with the outlet 51 opening in its center, FIGS. 1( a) and 1(b) and 6 show a wide gap between the outlet side wall 50 and the outlet-side sliding curved surface 34, but in fact, the outlet side wall 50 and the outlet-side sliding curved surface 34 face each other with a small clearance between them in areas other than the outlet 51.

[0026] A small closing projection 53 protruding laterally is provided near the center of the arcuate end 48a. The closing projection 53 fits into the projection-receiving recess 43 of the outlet side portion 28a when the cover member 46 is closed over the upper opening 30 of the cylindrical portion 28.

[0027] A pressing portion side wall 52 that intersects with the top plate 48 is provided on the arcuate end 48b of the top plate 48. The pressing portion side wall 52 protrudes from the top plate 48 in the same direction as the outlet side wall 50. When the cover member 46 is closed over the upper opening 30 of the tubular portion 28 at approximately a right angle to the insertion direction, the pressing portion side wall 52 closes the side opening 32 and has its tip overlapping the inside of the pressing portion side portion 28b of the tubular portion 28. The outer surface of the pressing portion side wall 52 is approximately perpendicular to the top plate 48 for about half the length from the top plate 48, and from a position closer to the tip than the halfway point, it becomes more distant from the arcuate end 48b as it approaches the tip. The inner surface of the pressing portion side wall 52 is approximately perpendicular to the top plate 48, and the thickness of the pressing portion side wall 52 gradually decreases as it approaches the tip. The vertical length of the pressing portion side wall 52 is slightly shorter than that of the outlet side wall 50, and the pressing portion side wall 52 protrudes downward when attached to the upper opening 30 of the tubular portion 28. The pressing portion side wall 52 is formed of a sliding curved surface that fits along the pressing portion side sliding curved surface 36 with a small clearance.

[0028] The corner of the top plate 48 between the arcuate end 48b and the pressing portion side wall 52 forms a pressing portion 55 that presses down the cover member 46 to open it when the powder 11 is taken out.

[0029] Side walls 54 that are continuous with the outlet side walls 50 are provided on the straight side edge portions 48c of the top plate 48. The side walls 54 are planar plates that are positioned approximately perpendicular to the top plate 48 and are overlapped on the inside of the side surface portions 28c when the cover member 46 is closed on the upper opening 30 of the tubular portion 28 at approximately right angles to the insertion direction. The side walls 54 are provided on approximately half of the top plate 48 on the outlet side wall 50 side, and have a triangular shape in the direction intersecting with the top plate 48, with one side continuing with the straight side edge portions 48c of the top plate 48, one side continuing with the end of the outlet side wall 50, and the remaining side being spaced apart from the top plate 48 and inclined relative to the top plate 48.

[0030] A rotation shaft 56 is provided on each of the pair of straight side edges 48c of the top plate 48, near the middle of the straight side edge 48c in the longitudinal direction. The rotation shaft 56 is cylindrical and has an axis that is perpendicular to the longitudinal direction of the straight side edge 48c and parallel to the top plate 48. The rotation shaft 56 has a diameter that allows it to rotatably fit into the bearing recess 42 of the inside plug 20. The diameter of the rotation shaft 56 is larger than the thickness of the top plate 48, and approximately half of the bottom of the rotation shaft 56 protrudes from the underside of the top plate 48. The pair of rotation shafts 56 have different protrusion lengths from the straight side edges 48c, with one protruding by approximately the same amount as the thickness of the side surface 28c of the tubular portion 28. Therefore, when the cover member 46 is attached to the tubular portion 28, the pair of rotation shafts 56 do not protrude from the outer surface of the side surface 28c of the tubular portion 28. The other end is slightly longer than the thickness of side surface 28c of tubular portion 28, and is provided with a thin rod-shaped locking protrusion 58 that is flush with the protruding tip and protrudes from the side peripheral surface intersecting the axial direction of rotation shaft 56. Locking protrusion 58 protrudes in the same direction as the protruding direction of outlet side wall 50 and pressing portion side wall 52, and at a substantially right angle to the surface direction of top plate 48.

[0031] When attaching the cover member 46 to the tubular portion 28, the outlet side wall 50 of the cover member 46 faces the outlet side portion 28a, the pressing portion side wall 52 faces the pressing portion side portion 28b, the pair of rotating shafts 56 face the bearing recesses 42, and the top plate 48 is pressed from above. The side portion 28c elastically deforms slightly, widening the opening of the bearing recesses 42 and allowing the rotating shafts 56 to be inserted. When the elastic deformation of the side portion 28c is restored, the rotating shafts 56 do not come off and are attached so that they can rotate about their axis. By attaching the cover member 46 to the tubular portion 28, the space surrounded by the bottom plate portion 24, the tubular portion 28, and the cover member 46 becomes a measuring chamber 60 for measuring the powder 11.

[0032] Next, a method of using the powder measuring container 10 of this embodiment will be described. First, powder 11, such as medicine, seasoning, or instant coffee, is placed in the container body 12, and the inner stopper 20 is attached to the container opening 16 of the container body 12. Next, the cover member 46 is attached to the inner stopper 20. Alternatively, the inner stopper 20 may be attached to the container body 12 after the cover member 46 has been attached thereto first.

[0033] With the cover member 46 in a closed state, a cap 62 that covers the inside stopper 20 is removably attached to the container opening 16 of the container body 12. As shown in Figures 5 and 6, the cap 62 has a circular upper surface and a cylindrical side surface that is continuous with the upper surface, and the inner peripheral surface of the side surface is formed with a female thread 64 that screws onto the male thread 18 of the container opening 16 of the container body 12, and is attached to the container body 12 by screwing. The cap 62 is sized so that, when screwed onto the container body 12, there is a space between the upper surface of the cap 62 and the inside stopper 20 and the cover member 46 attached to the inside stopper 20. A cylindrical sealing tube portion 66 is provided on the backside of the upper surface of the cap 62. The sealing tubular portion 66 is formed concentrically with the side surface of the cap 62, has an inner diameter that provides a space between the tubular portion 28 and the cover member 46 when the cap 62 is closed on the container body 12, and has a length in the protruding direction that is shorter than the side surface of the cap 62 and is long enough to abut against the upper surface of the flange portion 26 of the inside plug 20. When the cap 62 is closed, the sealing tubular portion 66 abuts against the flange portion 26 of the inside plug 20, preventing the inside plug 20 from loosening from the container body 12 and keeping the inside of the container airtight. The cap 62 is transported and stored in the locked state.

[0034] As shown in Figures 1(a) and 1(b), 2, 4, and 6, the cover member 46 is in a closed state when the top plate 48 is parallel to the bottom plate 24. The top plate 48 and the pressing portion side wall 52 of the cover member 46 close the upper opening 30 and the side opening 32 of the tubular portion 28, preventing powder 11 from escaping from the outlet 51. At this time, the inlet 38 of the inner plug 20 communicates with the inside of the container body 12 and the measuring chamber 60. The closing projection 53 of the top plate 48 is inserted into and abuts against the projection-receiving recess 43 of the outlet side portion 28a, positioning the cover member 46 and ensuring stable closure without being pushed into the measuring chamber 60. The locking projection 58 abuts against and locks against the locking rib 44 near the pressing portion side portion 28b of the tubular portion 28, maintaining the closed state with a predetermined force.

[0035] When removing the powder 11 from the container body 12, the cap 62 is removed, and as shown in Figure 1(a), the container body 12 is slowly inverted while the cover member 46 remains closed on the tubular portion 28. The powder 11 in the container body 12 passes through the inlet 38 and moves into the measuring chamber 60, where it is taken in.

[0036] Thereafter, as shown in FIG. 1(b), when the container body 12 is returned to a horizontal position with the outlet side 28a of the tubular portion 28 facing downwards, the powder 11 is sufficiently filled up to the vicinity of the outlet 51 located within the measuring chamber 60, and the excess powder 11 that has entered the measuring chamber 60 and is above the tip 40a of the blocking portion 40 is returned to the container body 12, and a certain amount of powder 11 that fills up to the tip 40a of the blocking portion 40 remains in the measuring chamber 60, and the powder 11 is measured to a certain volume.

[0037] Then, when the pressing portion 55 of the cover member 46 is pressed down with a finger or the like with a predetermined force and the top plate 48 of the cover member 46 is rotated around the rotation axis 56, the pressing portion side wall 52 of the cover member 46 is pressed into the inside of the tubular portion 28, and the top plate 48 stops at a position where it contacts the tip portion 40a of the closing portion 40 of the inside plug 20. In this state, as shown in FIG. 1(c), the outlet side wall 50 is lifted up from the outlet side portion 28a of the tubular portion 28, exposing and opening the outlet 51, allowing the powder 11 in the measuring chamber 60 to be shaken out and dropped for collection. Here, the closing protrusion 53 is located at the upper center of the outlet 51, which serves as a guide when pouring the powder 11 and makes it easy to determine the pouring position.

[0038] By the above operation, the powder 11 filling the measuring chamber 60 passes through the outlet 51 and is entirely removed. At this time, the top plate 48 comes into contact with the tip 40a of the closing portion 40 of the inside plug 20, blocking off the container body 12 and the measuring chamber 60, preventing the powder 11 contained in the container body 12 from being added to the measuring chamber 60. The tip 40a is bent slightly toward the boundary between the pressing portion side portion 28b and the bottom plate portion 24, ensuring contact with the top plate 48. A pair of side walls 54 are provided on both sides of the outlet side wall 50 of the cover member 46, continuing from the straight side edge portion 48c of the top plate 48, to prevent the powder 11 from spilling out from the sides when being removed from the outlet 51.

[0039] When the cover member 46 is in the open state, the locking projection 58 of the cover member 46 abuts against and locks onto the locking rib 44 at a portion close to the outlet side portion 28a of the tubular portion 28, and the open state is maintained with a predetermined force, so that the cover member 46 will not accidentally close when the powder 11 is taken out.

[0040] When the powder 11 is removed and the measuring chamber 60 is empty of powder 11, the powder measuring container 10 is returned to its upright position and the vicinity of the outlet side wall 50 of the top plate 48 of the cover member 46 is pressed down to return to the closed state as shown in Figures 2 and 4. Note that even if the cap 62 is closed while the cover member 46 is in the open state, the cap 62 will press down the top plate 48 and return to the closed state. In the closed state, the locking projection 58 abuts and locks against a portion of the locking rib 44 near the pressing portion side portion 28b of the tubular portion 28, maintaining the closed state with a predetermined force. Then, as shown in Figure 6, the cap 62 is attached and the container is stored.

[0041] In this way, when switching the cover member 46 between the open and closed states, the pressing portion 55 is pressed down with a force greater than or equal to a predetermined value, or the area around the closing protrusion 53 on the opposite side is pressed down. This causes the locking protrusion 58 to elastically deform and move over the locking rib 44 while abutting against it, allowing the top plate 48 to rotate and switch between the open and closed states. If the locking protrusion 58 and the locking rib 44 were installed inside the measuring chamber 60, powder 11 might get caught between the locking protrusion 58 and the locking rib 44, adversely affecting smooth opening and closing. Therefore, the locking protrusion 58 and the locking rib 44 are installed outside the measuring chamber 60. This enables smooth opening and closing. When the locking protrusion 58 abuts against the end of the locking rib 44 and moves over it, a force acts to return until it moves over the end, and then a force acts to move forward after it moves over the end, creating a clicking sensation.

[0042] When the cover member 46 rotates, the outlet side wall 50 of the cover member 46 moves along the outlet-side sliding curved surface 34 of the outlet side portion 28a of the tubular portion 28, and the pressing portion side wall 52 moves along the pressing portion-side sliding curved surface 36 of the pressing portion side portion 28b. This maintains a small, constant clearance between the inner plug 20 and the cover member 46, regardless of the position at which the cover member 46 rotates. This prevents the powder 11 from moving through the gap between the inner plug 20 and the cover member 46, ensuring accurate measurement. It also prevents the powder 11 from spilling out and soiling the surrounding area, and prevents the powder 11 from getting caught in the gap between the inner plug 20 and the cover member 46 and interfering with rotation. The size of the clearance between the inner plug 20 and the cover member 46 can be set arbitrarily, as long as it allows the cover member 46 to move smoothly without spilling the powder 11.

[0043] The powder measuring container 10 of this embodiment reliably contains powder 11 and allows the contained powder 11 to be reliably measured and dispensed in a desired amount with a simple operation. When the cover member 46 is rotated to dispense powder 11, the outlet side wall 50 of the cover member 46 moves along the outlet-side sliding curved surface 34 of the outlet side portion 28a of the tubular portion 28, and the pressing portion side wall 52 moves along the pressing portion-side sliding curved surface 36 of the pressing portion side portion 28b, thereby maintaining a constant clearance between the inside plug 20 and the cover member 46. This prevents the powder 11 from moving through the gap between the inside plug 20 and the cover member 46, ensuring accurate measurement. Furthermore, the powder 11 is prevented from spilling out and soiling the surrounding area, and the powder 11 is prevented from getting caught in the gap between the inside plug 20 and the cover member 46, hindering rotation. The powder 11 is taken out only from the outlet 51 opening in the outlet side wall 50, and the side walls 54 continuing on both sides of the outlet side wall 50 prevent the powder 11 from spilling or spreading to the side, and the entire amount of the measured powder 11 can be poured into a predetermined place, facilitating the take-out operation.

[0044] Because the locking protrusions 58 and the locking ribs 44 abut against each other and lock, the closed or open state can be maintained with a moderate force. When removing the powder 11, the container will not accidentally close, ensuring a stable removal operation of the powder 11, and will not accidentally open even when closed, ensuring safety. When switching between the open and closed states, a clicking sensation occurs as the locking protrusions 58 abut against and overcome the ends of the locking ribs 44, making it easy to recognize that the container has switched between the closed and closed states.

[0045] When the outlet 51 is opened, the back surface of the top plate 48 comes into contact with the tip 40a of the blocking portion 40 of the inner plug 20, blocking the space between the inlet 38 and the outlet 51, preventing the powder 11 in the container body 12 from entering the measuring chamber 60, and allowing accurate measuring despite the simple structure.

[0046] The powder measuring container of this invention is not limited to the above embodiment, and the shape of the container body can be freely changed, and the shape and height of the cylindrical portion and the closing portion of the inner stopper can be changed to change the volume of the measuring chamber. The powder to be stored can be other than medicines, seasonings, and instant coffee, and the shape and particle size of the powder can also be freely changed, and it can be granules made by compacting powder and forming them into slightly larger particles, or fine crystals such as granulated sugar.

[0047] In this embodiment, the inside plug 20 is provided with the pressing portion-side curved sliding surface 36, and the pressing portion 55 of the cover member 46 is provided with a pressing portion side wall 52 that follows the rotational path of the pressing portion-side curved sliding surface 36. However, it is also possible to maintain a constant clearance by providing a curved sliding surface on one side and using a plate-like end surface without a side wall on the other. For example, if the cover member 46 is plate-shaped, the pressing portion side portion 28b is shaped to rise up to the height of the top plate 48. If the inside plug 20 is plate-shaped, such as the bottom plate portion 24, it is preferable to eliminate the pressing portion side portion 28b and have the pressing portion side wall 52 of the cover member 46 have an extended shape.

[0048] Regarding the outlet-side curved sliding surface 34, the inner plug 20 is provided with the outlet-side curved sliding surface 34, and the outlet 51 of the cover member 46 is provided with an outlet side wall 50 having a curved sliding surface, but even if the inner plug 20 does not have a curved sliding surface, it is possible to maintain a constant clearance between the upper opening 30 and the outlet side wall 50, and furthermore, the outlet through which the contents are taken out can still take out the contents even without the outlet side wall 50 or side wall 54. However, at the outlet 51, a longer curved sliding surface can more reliably prevent the contents from leaking or getting caught, and the presence of the outlet-side curved sliding surface 34 and the outlet side wall 50 makes it easier to pour the contents in the desired location.

[0049] Furthermore, in the above embodiment, the rotation shaft 56 is provided in the cover member 48 and the bearing recess 42 is provided in the inside plug 20, but the bearing recess may be provided in the cover member 48 and the rotation shaft may be provided in the inside plug 20. Also, the locking rib 44 and the locking projection 58 may be provided on the inside plug 20 side and the cover member 48 side, respectively.

[0050] Additionally, in the above embodiment, the tubular portion 28 protrudes upward by a predetermined height, but if the bottom plate portion 24 is provided below the flange portion 26, the tubular portion 28 can have a shape that does not protrude from the flange portion 26, and a container that can be sealed without providing the cap 62 with a sealing tubular portion 66 is obtained. Also, in the above embodiment, the cross-sectional shape of the tubular portion 28 parallel to the bottom plate portion 24 is a substantially rectangular shape that is long in one direction, but as long as the metering operation and the dispensing operation are possible, the outlet side portion 28a and the pressing portion side portion 28b may be straight, or the side portions may be curved, and they may not be symmetrical.
