As shown in FIG. 3, the measuring container is composed of a container body 2, a lower lid member 10, and an upper lid member 24. These members can be formed of a synthetic resin unless otherwise specified.

  The container body 2 has a wide-mouthed mouth-and-neck portion 4 that stands up from the trunk. A locking rib 6 is provided around the outer surface of the mouth / neck portion 4.

  The lower lid member 10 has a first peripheral wall 12 that is non-rotatably fitted to the mouth / neck portion 4, and a horizontal first that closes the upper surface of the first peripheral wall 12 at the upper end of the first peripheral wall 12. The lid plate 16 is connected.

  A concave groove that engages with the locking rib 6 is provided on the inner surface of the first peripheral wall 12 to prevent the lower cover member 10 from being unexpectedly pulled out. Further, non-rotating means (not shown in the figure, such as a concave portion and a convex portion) are provided on the inner surface of the first peripheral wall 12 and the outer surface of the mouth-and-neck portion 4.

  The illustrated first peripheral wall 12 protrudes from the lower half 12a having a large outer diameter via the upward stepped portion 13 to the upper half 12b having a small diameter (see the left half of FIG. 3). And the upper part of the step part 13 is dented in a part of the circumferential direction of the lower half part 12a of the 1st surrounding wall 12, and the engagement recessed part 14 is laterally provided (refer the right half figure of FIG. 3).

  The first cover plate 16 has a measuring cylinder portion 18 and a communication port 20 at an eccentric position away from the center O, as indicated by a dotted line in FIG.

  The measuring cylinder portion 18 is formed in a bottomed cylinder shape in which the first cover plate 16 is recessed. In the illustrated example, the bottom portion of the measuring cylinder portion 18 is formed in a round bottom, but the structure can be changed as appropriate.

  The communication port 20 is provided away from the measuring tube portion 18. The communication port 20 shown in the figure extends from the vicinity of the measuring tube portion 18 in the circumferential direction, as shown by a dotted line in FIG. This is because the overall shape of the measuring cylinder portion 18 is made to correspond to the shape of the raised portion described later. However, the form can be changed as appropriate.

  The communication port 20 and the measurement tube portion 18 are configured so that the storage tube portion 34 of the upper cover member 24 to be described later is connected to either the communication port 20 or the measurement tube portion 18 by rotating the upper cover member 24 around the center O of the first cover plate 16. It arrange | positions in the position which can face both. However, the communication port 20 and the measuring tube portion 18 are not arranged on the same diameter. This is because it is possible to close the lower end of a later-described discharge cylinder portion 38 with the first lid plate 16 in a later-described weighing operation mode.

  The upper lid member 24 is installed on the first peripheral wall 12 so as to be rotatable in one direction and in the opposite direction, and is provided on the inner side of the second peripheral wall 26 and the upper surface of the first cover plate 16. And a second cover plate 32 in contact with the.

  In the illustrated example, the second peripheral wall 26 has a lower portion 26 a fitted to the outer surface of the first peripheral wall 12 as shown in FIG. 3, and extends from the fitting portion to the upper side of the lower lid member 10. When the upper lid member 24 is rotated, the second peripheral wall 26 may be gripped. A cutout 28 is provided at the upper end of the second peripheral wall 26.

  A positioning stopper 30 projects downward from the second peripheral wall 26. This positioning stopper 30 is inserted into the engaging recess 14 to constitute the positioning means P. That is, when the positioning stopper 30 hits one end of the horizontally long engaging recess 14, the state shown in FIG. 1 (measuring operation mode) is obtained, and when it hits the other end, the state shown in FIG. 7 (referred to as discharge operation mode). To be formed. But the structure of the positioning means P can be changed suitably. For example, an engagement recess may be provided on one of the outer surface of the first peripheral wall 12 and the inner surface of the second peripheral wall 26, and a positioning stopper that engages with the engagement recess may be projected from the other surface.

  The second cover plate 32 has a storage cylinder part 34 facing the measurement cylinder part 18 in the measurement operation mode of FIG. 1 and a position that overlaps the measurement cylinder part 18 by rotating the upper cover member 24 (an almost rotationally symmetric position). ) And a discharge cylinder portion 38. Further, the second lid plate 32 has a raised portion 36 that is continuous with the storage cylinder portion 34. Except for the formation part of these storage cylinder part 34, the discharge cylinder part 38, and the protruding part 36, it is flat and is in close contact with the upper surface of the first cover plate 16.

  The storage cylinder part 34 has a role of storing contents entering from the communication port 20 by turning the container upside down in the state shown in FIG. The storage cylinder part 34 is formed by raising the second cover plate part above the measurement cylinder part 18 into a top cylinder shape.

  The internal volume of the storage cylinder portion 34 is equal to or greater than the internal volume of the measurement cylinder portion 18.

  Further, as shown in FIG. 3, a communication port 35 is cut out in the lower half of the cylindrical wall portion on the raised portion 36 side of the storage cylindrical portion 34.

  The raised portion 36 extends in the circumferential direction from the communication port 35 of the storage tube portion 34 to the communication port 20 in the weighing operation mode of FIG. Then, a communication groove 37 is formed on the back surface of the raised portion 36 as shown in FIG.

  In the illustrated example, the communication groove 37 becomes deeper and wider as it approaches the communication port 20. This is to make it easy for the contents such as powder to flow inside. However, the structure can be changed as appropriate.

  The discharge cylinder part 38 has a role of discharging the contents measured in the measurement cylinder part 18 to the outside. The discharge cylinder portion 38 is formed by opening a second cover plate portion above the measuring cylinder portion 18 and erecting a cylinder wall having an upper end opening from the hole edge.

It is assumed that the lower surface of the discharge cylinder portion 38 is closed with the lower surface of the first lid plate 16 in the measurement operation mode (see FIG. 1). In the illustrated example, the discharge cylinder portion 38, the storage cylinder portion 34, and the second peripheral wall 26 have substantially the same height, and the above-described notch 28 is provided at the upper end portion of the second peripheral wall 26 adjacent to the discharge cylinder portion 38. Yes.

  According to this configuration, when the weighing container is turned upside down in the weighing operation mode of FIG. 1, the contents in the container body 2 are stored from the communication port 20 through the communication groove 37 as shown in FIG. Enter 34. If the communication groove 37 is not provided, at this stage, the storage cylinder part 34 is first opposed to the communication port 20, and then the storage cylinder part 34 is rotated to the position facing the measurement cylinder part 18. Become. The operation is simplified by the configuration of the configuration of the present invention.

  When the container is returned to the upright state, the contents in the storage cylinder part 34 flow down into the measurement cylinder part 18 as shown in FIG. In the illustrated example, since the internal volume of the storage cylinder portion 34 is larger than the internal volume of the measurement cylinder portion 18, some contents remain in the storage cylinder portion 34 without entering the measurement cylinder portion 18. When the upper lid member 24 is rotated in the opposite direction with respect to the lower lid member 10, the cylinder wall of the storage cylinder portion 34 acts so as to cut through the remaining contents. The remaining contents are moved together with the storage cylinder portion 34, returned to the container body 2 from the communication port 20, and a fixed amount of contents are measured in the measurement cylinder portion 18. At the same time, the discharge cylinder part 38 moves to a position facing the measuring cylinder part 18 (see FIG. 11C).

  When the container is turned upside down again, a certain amount of contents in the measuring tube portion 18 are discharged through the discharge tube portion 38.
