Description

The present invention relates to a measuring container equipped with a mechanism for measuring the contents.

Conventionally, various measuring containers equipped with a measuring mechanism for the contents have been proposed.

For example, Patent Document 1 discloses a measuring container (10) that includes an inner stopper (18) attached to a container opening (14) of a container body (12) and a transparent cover member (30) that forms a measuring chamber (45) between the inner stopper (18) and a bottom plate portion (20) provided on the inner stopper (18). Powder (56) contained in the container body (12) is allowed to flow into the measuring chamber (45) from a measuring chamber inlet (30) formed by penetrating the bottom plate portion (20), and is then measured using a scale (54) formed on the cover member (30). After that, the measured powder (56) is discharged from the outlet (44) of the cover member (30).
The reference numerals in parentheses above refer to the reference numerals given in Patent Document 1.

Furthermore, Patent Document 2 discloses a measuring container comprising a lower cover member (10) non-rotatably attached to the mouth neck portion (4) of a container body (2), and an upper cover member (24) rotatably attached to the lower cover member (10), in which the lower cover member (10) is provided with a measuring tube portion (18) and a communication port (20), and the upper cover member (24) is provided with a storage tube portion (32), a communication groove (37) communicating with the storage tube portion (32), and a discharge tube portion (38). In the measuring container disclosed in Patent Document 2, first, the upper cover member (24) is rotated to set the container to a measuring operation mode in which the storage tube portion (34) of the upper cover member (24) is positioned opposite the measuring tube portion (18) of the lower cover member (10). When the container is then turned upside down in this state, the contents in the container body (2) flow from the communication port (20) through the communication groove (37) into the storage tube portion (34). When the container is returned to its upright position, the contents in the storage tube portion (34) flow down into the measuring tube portion (18), and then, by rotating the top cover member (24) in the opposite direction, the contents that have flowed down into the measuring tube portion (18) are measured by being leveled off, while the discharge tube portion (38) of the top cover member (24) is moved to a position opposite the measuring tube portion (18), and the container is then turned upside down again, so that the measured contents in the measuring tube portion (18) are discharged from the discharge tube portion (38).
The reference numerals in the parentheses above refer to the reference numerals given in Patent Document 2.

The measuring container disclosed in Patent Document 1 is said to enable a required amount to be accurately measured and dispensed with a simple operation.
However, when the powder (56) contained in the container body (12) is caused to flow into the measuring chamber (45) and measured using the scale (54) formed on the cover member (30), the amount of flow must be adjusted by tilting the container body (12) little by little while being careful not to let an excessive amount of powder flow into the measuring chamber (45), and if the amount of flow becomes excessive, the user is forced to return part of the powder to the container body (12) and readjust it. In particular, for a presbyopic person who has difficulty seeing small objects close at hand, the operation of accurately adjusting the amount of flow in accordance with the scale can be a stressful operation.

On the other hand, in the measuring container disclosed in Patent Document 2, the contents that flow down into the measuring tube (18) are measured by leveling them off, so that accurate measurement with good reproducibility can be expected.
However, before the contents can be measured and dispensed, it is necessary to rotate the top cover member (24) and turn the container upside down, and this operation is not so simple since it is a combination of multiple actions. Moreover, in order to rotate the top cover member (24), it is necessary to hold the container body (2) with one hand and rotate the top cover member (24) with the other hand, which is inconvenient because both hands are occupied.

Therefore, the inventors conducted extensive research to provide a measuring container that can dispense a measured amount of contents with a simple action that can be performed with one hand, and as a result, they have completed the present invention.

The measuring container according to the present invention is a measuring container equipped with a measuring mechanism, and includes a gripping part, a storage part detachably attached to the top surface side of the gripping part, and a rotating body rotatably supported within the gripping part. The rotating body has an arc surface parallel to the rotation axis and along an arc centered on the rotation axis. The rotation of the rotating body is controlled so that the measuring part recessed toward one end side along the rotation direction of the arc surface moves back and forth between a supply port through which the contents stored in the storage part are supplied and a discharge port opening on the side surface of the gripping part. A guide passage formed in an arc shape centered on the rotation axis is provided in the rotating body, and the guide passage contains a weight that can move within the guide passage.

According to the present invention, a measured amount of contents can be dispensed with the simple action of shaking the measuring container.

[First embodiment]
First, a first embodiment of the present invention will be described.
FIG. 1 is a perspective view showing an outline of a measuring container according to this embodiment, FIG. 2 is a front view thereof, FIG. 3 is a side view thereof, and FIG. 4 is a rear view thereof.

The measuring container 1 shown in these figures comprises a gripping part 2, a storage part 3 that is removably attached to the top side of the gripping part 2, and a rotating body 4 that is rotatably supported within the gripping part 2. It is configured to measure the contents stored in the storage part 3, preferably powdered or granular seasonings such as salt, sugar, pepper, etc., while dispensing a predetermined measured amount of the contents.

In this embodiment, the top, bottom, left, right, length and width directions are defined when the measuring container 1 is viewed from the front in an upright position (as shown in FIG. 2).

The rotating body 4 can be formed to have a generally fan-shaped appearance, and has an arc surface 40 that is parallel to the rotation axis and follows an arc centered on the rotation axis (see Figures 5, 11, and 12). It is preferable that the arc surface 40 is formed so that the width perpendicular to the rotation direction and the curvature along the rotation direction are constant, and a measuring section 41 that is recessed with a predetermined volume is provided at a position near one end of the arc surface 40 along the rotation direction.

In the illustrated example, the rotating body 4 has an axial hole 42 drilled in the center of the arc that forms the arc surface 40 that is the center of rotation, and the axial rod 43 pressed into this axial hole 42 serves as the rotation axis and is supported within the grip part 2, but this is not limited to this. For example, if there are no problems with strength, a cylindrical protrusion may be molded integrally with the center of rotation of the rotating body 4, and such protrusion may serve as the rotation axis.

The rotating body 4 is provided with a guide passage 44 formed in an arc shape centered on the rotation axis, and the guide passage 44 houses the weight 5 that can move within the guide passage 44. This allows the weight 5 housed in the guide passage 44 to be guided by the guide passage 44 and move within the guide passage 44 so as to describe an arc-shaped trajectory around the rotation axis. The weight 5 housed in the guide passage 44 is preferably a sphere that can roll within the guide passage 44.

In the illustrated example, the guide passage 44 is grooved on the side of the rotating body 4, but is not limited to this. For example, the rotating body 4 may be composed of two members divided by a plane perpendicular to the rotation axis, and an arc-shaped groove may be formed on one or both of the divided faces, so that the guide passage 44 is hollow inside the rotating body 4 when the two members are combined. The guide passage 44 provided in the rotating body 4 is usually concentric with the arc surface 40 of the rotating body 4 and is provided so that the curvature along the rotation direction is constant, but it can also be appropriately adjusted so that the curvature changes along the rotation direction as necessary.

The grip portion 2 in which the rotating body 4 is journalled can be formed to have a cylindrical appearance with a discharge port 20 opening on the side, as shown in the figure.
In addition, the storage section 3, which is removably attached to the top surface side of the gripping section 2, can be formed into a bottle shape in which one end of a cylindrical body 32 of roughly the same diameter as the gripping section 2 is connected to a mouth 30, which is an opening for removing the contents, via a shoulder 31 which tapers in diameter like a truncated cone, as shown in the figure, and it is preferable that the storage section 3 is attached coaxially with the gripping section 2 to the top surface side of the gripping section 2 in an inverted state with the mouth 30 facing down.

In the illustrated example, the gripping part 2 includes a gripping part body 21 and a canopy part 22. The canopy part 22 has an attachment part 22a at the center thereof, which opens on the top surface side of the canopy part 22 and to which the storage part 3 is detachably attached, for example, by screwing, fitting, or pressing the mouth part 30 of the storage part 3. If necessary, a tapered part corresponding to the inclination of the shoulder part of the storage part 3 can be provided around the attachment part 22a so that the storage part 3 can be attached in a good fit. Furthermore, the bottom surface side of the canopy part 22 has a supply port part 22b that opens directly below the attachment part 22a and serves as a supply port for the contents stored in the storage part 3, and a pair of tapered protrusions 22c that hang down parallel to each other with the supply port part 22b in between.

The grip body 21 includes a cylindrical base 21a and a pair of side walls 21b that rise parallel to each other and spaced apart from each other above the base 21a. The outer surface of each side wall 21b is preferably formed to be flush with the outer peripheral surface of the base 21a. Furthermore, a recess 21c that tapers toward the base 21a is formed on the inner surface of each side wall 21b so that the protrusion 22c on the canopy 22 can be inserted. By inserting the protrusion 22c on the canopy 22 into this recess 21c, the canopy 22 can be attached to the grip body 21 while aligning it around the central axis C, and a bearing portion that supports the rotation axis of the rotating body 4 is formed between the bottom end 21d of the recess 21c and the tip 22d of the protrusion 22c.

In this way, the rotating body 4 is inserted between a pair of side walls 21b of the grip body 21, and the rotation axis of the rotating body 4 is supported by the bottom end 21d of the recess 21c formed on the inner surface of each side wall 21b. By attaching the canopy 22 to the grip body 21, the rotating body 4 can be rotatably supported within the grip 2. At this time, one of the openings formed between the side walls 21b becomes the discharge outlet 20 that opens on the side surface of the grip 2.

In this way, when the rotating body 4 is supported inside the gripping portion 2, it is preferable to adjust the shape and dimensions of each part appropriately so that the axis of rotation of the rotating body 4 is perpendicular to the central axis C of the gripping portion 2. Furthermore, it is preferable to adjust the shape and dimensions of each part appropriately so that the protrusion 22c provided on the canopy portion 22 hangs down at a distance between the rotating body 4 and the rotating body 4 that forms an appropriate clearance that does not interfere with the rotation of the rotating body 4 according to the thickness of the rotating body 4, and so that when inserted into the recess 21c formed on the inner surface of each side wall portion 21b, it fits flush with the inner surface.

In this embodiment, the rotation of the rotating body 4 is controlled so that the measuring section 41 recessed in the arc surface 40 of the rotating body 4 moves back and forth between the supply port 22b through which the contents stored in the storage section 3 are supplied and the discharge port 20 opening on the side of the gripping section 2. In the illustrated example, the measuring section 41 is located directly below the supply port 22b (see FIG. 11), and the measuring section 41 moves to the discharge port 20 (see FIG. 12) by rotating the rotating body 4 90° from that state, and returns to directly below the supply port 22b when rotated in the opposite direction. The measuring section 41 is controlled to move back and forth between the supply port 22b and the discharge port 20 by rotating the rotating body 4 within an angle range of 90°.

To control the rotation of the rotating body 4 in this manner, for example, a rotation control section that abuts against the rotating body 4 and controls the rotation of the rotating body 4 may be provided between a pair of side wall sections 21b on which the rotating body 4 is journalled, depending on the shape of the rotating body 4. In the illustrated example, when the end face of the rotating body 4 on the front side is defined as the front end face 45 and the end face of the rotating body 4 on the rear side is defined as the rear end face 46 with respect to the rotation direction (travel direction) of the rotating body 4 when the measuring unit 41 moves from the supply port 22b toward the discharge port 20 (hereinafter, the "front end face" and "rear end face" of the rotating body 4 will follow this definition), when the measuring unit 41 moves to the discharge port 20, a front end rotation restricting part 21e abuts against the front end face 45 of the rotating body 4 to restrict the rotation of the rotating body 4, and when the measuring unit 41 moves to just below the supply port 22b, a rear end rotation restricting part 21f abuts against the rear end face 46 of the rotating body 4 to restrict the rotation of the rotating body 4 is provided between the pair of side walls 21b on which the rotating body 4 is journaled.

In this embodiment, the measuring section 41 recessed in the arc surface 40 of the rotating body 4 is provided so that when it is positioned directly under the supply port 22b, the contents contained in the storage section 3 are supplied so as to fall into the measuring section 41 under its own weight, and when the rotating body 4 moves toward the discharge port 20 as it rotates, the supplied contents are leveled and measured on the edge of the supply port 22b. The measuring section 41 is provided near one end along the rotation direction of the arc surface 40 on the front end surface 45 side of the rotating body 4, and when the contents supplied from the supply port 22b to the measuring section 41 are leveled and measured, the supply port 22b is blocked by the arc surface 40 of the rotating body 4 (see Figures 11 and 12).

In this way, when the contents supplied from the supply port 22b to the measuring section 41 are leveled and measured, in order to effectively prevent leakage of the contents, it is preferable that the bottom side of the canopy section 22 has a sliding surface 22e against which the arcuate surface 40 of the rotating body 4 slides when the rotating body 4 rotates, which is formed with the same curvature as the arcuate surface 40 of the rotating body 4 along the rotation direction of the rotating body 4. It is preferable that the supply port 22b is provided so as to open into this sliding surface 22e (see FIG. 8).

Then, the measured amount of contents is discharged from the discharge port 20 when the rotating body 4 rotates and the measuring section 41 moves to the discharge port 20.

As described above, the measuring container 1 is configured so that the rotating body 4 rotates to measure the contents contained in the storage section 3 while discharging a predetermined amount of the measured contents. The rotating body 4 is provided with a guide passage 44 formed in an arc shape centered on the rotation axis, and this guide passage 44 contains a weight 5 that can move within the guide passage 44.

Therefore, when the measuring container 1 is swung so that the discharge port 20 faces the target object as shown in FIG. 13, the weight 5 housed in the guide passage 44 of the rotating body 4 moves in the guide passage 44 in an arc-shaped trajectory around the rotation axis toward the front end face 45 of the rotating body 4 (the trajectory of the weight 5 at this time is shown by the dashed arrow in FIG. 11). As a result, when the weight 5 hits the end of the guide passage 44 while the center of gravity of the rotating body 4 moves toward the front end face 45, the rotating body 4 rotates due to this action, and the measuring section 41 recessed in the arc surface 40 of the rotating body 4 moves from directly below the supply port 22b toward the discharge port 20, so that a predetermined amount of the measured contents can be discharged from the discharge port 20 toward the target object.

Conversely, when the weighing container 1 is swung back so that the weight 5 housed in the guide passage 44 of the rotating body 4 moves toward the rear end surface 46 of the rotating body 4, the center of gravity of the rotating body 4 moves toward the rear end surface 46, while the weight 5 hits the opposite end of the guide passage 44, causing the rotating body 4 to rotate in the opposite direction (the trajectory of the weight 5 at this time is shown by the dashed arrow in Figure 12). As a result, the measuring section 41 recessed into the arcuate surface 40 of the rotating body 4 returns to directly below the supply port 22b, ready for the next operation.

Therefore, according to this embodiment, a predetermined amount of measured contents can be dispensed by a simple action of shaking the measuring container 1 once. For example, while cooking, a predetermined amount of measured contents can be dispensed by simply shaking the measuring container 1 held in one hand while holding a cooking utensil such as a frying pan in the other hand. Moreover, if the measuring section 41 recessed in the arc surface 40 of the rotating body 4 is provided with a volume for 1 g of the contents to be measured, for example, even if there is a request to dispense 3 g of contents, such a request can be met by simply repeating the action of shaking the measuring container 1 three times, and it is also possible to flexibly respond regardless of the requested amount of discharge.

In addition, in this embodiment, the clearance between the sliding surface 22e formed on the bottom side of the canopy portion 22 and the arc surface 40 of the rotating body 4 can be appropriately adjusted so that the rotating body 4 does not rotate unintentionally, but only rotates due to the action of the weight body 5 when the measuring container 1 is shaken, thereby preventing the contents from leaking out when not in use.

[Second embodiment]
Next, a second embodiment of the present invention will be described.
FIG. 14 is a perspective view showing an outline of the measuring container according to this embodiment, FIG. 15 is a front view of the same, FIG. 16 is a side view of the same, and FIG. 17 is a rear view of the same.

The measuring container 1 shown in these figures comprises a gripping part 2, a storage part 3 that is removably attached to the top side of the gripping part 2, and a rotating body 4 that is rotatably supported within the gripping part 2, and is configured to measure the contents stored in the storage part 3 while dispensing a predetermined amount of the measured contents, similar to the first embodiment.

The measuring container 1 in this embodiment differs from the first embodiment in that the volume of the measuring section 41 provided on the rotating body 4 is variable, and this embodiment will be described with a focus on this point.

In this embodiment, the rotating body 4 has an arc surface 40 that is parallel to the rotation axis and follows an arc centered on the rotation axis, as in the first embodiment, and a measuring section 41 that is recessed with a predetermined volume is provided at a position near one end of the arc surface 40 in the rotation direction, but in this embodiment, a slide member 4a provided with a sub-measuring section 41a that can communicate with the measuring section 41 is slidably attached to the rotating body 4 (see Figures 26 to 30).

The slide member 4a has a generally arc-shaped appearance and can be formed so as to be attached to the rotating body 4 concentrically with the arc surface 40 of the rotating body 4. It has an arc-shaped slide surface 40a with a larger curvature than the arc surface 40 of the rotating body 4, and a sub-measuring section 41a that is recessed to a predetermined volume is provided in this slide surface 40a.

The rotating body 4 has a guide portion 4b that matches the shape of the slide member 4a and is formed in an arc shape centered on the rotation axis, and the slide member 4a is slidably pressed into this guide portion 4b. This allows the slide member 4a to be slidably attached to the rotating body 4, but it is preferable to provide stoppers 4c and 4d on both ends of the slide member 4a to prevent the slide member 4a from falling off the rotating body 4.

In the illustrated example, the sub-measuring section 41a is positioned so that it communicates with the measuring section 41 when one of the stoppers 4c is in contact with the rotating body 4 (see FIG. 29). By communicating with the measuring section 41, the volume of the sub-measuring section 41a is added to the measuring section 41, and the volume of the measuring section 41 can be changed (increased) accordingly.

As shown in FIG. 29, the slide member 4a is formed so that one end opposite the side on which the sub-measuring section 41a is provided protrudes from the rotating body 4 when the measuring section 41 and the sub-measuring section 41a are in communication with each other. By doing so, the protruding side of the slide member 4a is pushed back into the rotating body 4, and the slide member 4a is slid clockwise from the state shown in FIG. 29, thereby eliminating communication between the measuring section 41 and the sub-measuring section 41a (see FIG. 30). As a result, the volume of the measuring section 41 can be changed (reduced) by the amount lost in the volume of the sub-measuring section 41a.

To change the volume of the measuring section 41 again, slide the slide member 4a counterclockwise from the state shown in FIG. 30. At this time, the slide member 4a may be slid by pushing the protruding side of the slide member 4a back into the rotating body 4, as described above, but as shown in the figure, the other stopper 4d may be provided to function as a knob, so that the side of the slide member 4a where the stopper 4d is provided can be pulled out from inside the rotating body 4 by hooking a fingertip on the stopper 4d, and the slide member 4a may be slid.

According to this embodiment, the slide member 4a, which is provided with a sub-measuring section 41a that can communicate with the measuring section 41, is slidably attached to the rotating body 4, making it possible to change the volume of the measuring section 41. This makes it possible to change the amount of content discharged when the measuring container 1 is shaken, depending on the changed volume of the measuring section 41.

As described above, this embodiment differs from the first embodiment described above in the above respects, but other configurations are common to the first embodiment. Therefore, the configurations common to the first embodiment are given the same reference numerals in the figures as in the first embodiment, and duplicate explanations will be omitted.

The present invention has been described above with reference to preferred embodiments, but it goes without saying that the present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the present invention.
