  A metering and dispensing container 1 shown in FIG. 1 includes an outer container 2, an inner container 3, and a measuring cap 4. The outer container 2 is made of a flexible material such as a synthetic resin, and is given squeeze property and restoration property. Such squeezing and restoring properties can be easily crushed by gripping the thickness of the barrel of the outer container 2 according to the physical properties of the flexible material to be used and applying force, but releasing the force. Then, it can implement | achieve by setting it as the range which returns to the original shape elastically. Further, the outer container 2 has a trunk portion 5, a bottom portion 6 provided continuously with the lower end of the trunk portion 5, and a mouth tube portion 7 provided upright at the upper end of the trunk portion 5. The portion 7 has a vent hole 8 which will be described later.

  The inner container 3 is disposed in the outer container 2 and contains liquid therein. The inner container 3 is formed by making a flexible material such as a synthetic resin thin, for example, so that it can no longer substantially exhibit restorability, and the volume decreases as the contained liquid decreases. It can be deformed. The outer container 2 and the inner container 3 may be configured as so-called double containers, which are independent containers, or the inner container 3 formed in a bag shape on the inner surface of the outer container 2 is easily laminated. It may be configured as a so-called delamination container. When configured as a delamination container, the inner container 3 is fixed to the outer container 2 (adhered in the axial direction, etc.) at the bottom 6 and the mouth tube part 7 of the outer container 2, and in the case of volume reduction deformation It is preferable that only the body portion of the inner container 3 be separated from the outer container 2. In this embodiment, the outer container 2 and the inner container 3 are configured as delamination containers, and the inner container 3 and the bottom 6 central portion of the outer container 2 are fixed. For example, the inner container 3 and the side surface of the outer container 2 It is also possible to fix a part of the linearly along the axial direction.

  A measuring cap 4 is attached to the mouth tube portion 7 of the outer container 2. The lower portion of the measuring cap 4 includes a mounting tube portion 9 that fits to the outer peripheral surface of the mouth tube portion 7 of the outer container 2, a flange portion 10 that protrudes inward from the upper portion of the mounting tube portion 9, It is comprised with the liquid introduction pipe 11 suspended from the flange part 10. FIG. The liquid guide pipe 11 is formed by projecting a part of the liquid guide pipe 11 outward in a flange shape, thereby constituting a sealing part 11 a for sealing the mouth tube part 7 of the outer container 2. In this embodiment, a screw portion 9a is provided on the inner surface of the mounting tube portion 9, and by screwing this with the screw portion 7a of the mouth tube portion 7, the measuring cap 4 and the outer container 2 are detachable. It is composed. Further, the upper portion of the measuring cap 4 stands on the measuring tube portion 12 provided continuously above the mounting tube portion 9, the bottom portion 13 projecting inward from the lower portion of the measuring tube portion 12, and the bottom portion 13. It is comprised by the pouring pipe 14 provided and the cover part 15 fitted to the upper part of the measurement cylinder part 12. As shown in FIG. The lower end of the extraction pipe 14 is inserted into the liquid introduction pipe 11, whereby the liquid introduction pipe 11 and the extraction pipe 14 communicate with each other. From the top lower surface 15 a of the lid portion 15, a cylindrical scattering prevention portion 15 b is suspended so as to accommodate the opening end of the extraction pipe 14, and liquid is externally attached to the side surface of the lid portion 15. A liquid discharge port 16 is provided for discharging the liquid. In this embodiment, a protrusion is provided on the upper portion of the measuring tube portion 12, and a concave groove provided in the cover portion 15 is fitted in this, but the fitting between the measuring tube portion 12 and the cover portion 15 is performed. The embodiment is not limited to this. The measuring cap 4 has an intake hole 17 communicating with the outside air in the flange portion 10, and a second reverse valve formed integrally with a first check valve 18 disposed in the liquid introduction pipe 11. A stop valve 19 is disposed so as to cover the intake hole 17. The position of the intake hole 17 is not particularly limited as long as it can communicate with the outside air even when the measuring cap 4 is closely fitted to the mouth tube portion 7 of the outer container 2.

  During transportation and storage, the mouth tube portion 7 of the outer container 2 is sealed by the inner plug 20. Using the inner plug 20 in this way is advantageous because it can prevent accidents in which liquid is discharged even when an unexpected pressing force is applied to the metering container 1, but the use of the inner plug 20 is advantageous. Not required. In use, when the measuring cap 4 is once removed from the outer container 2, the inner plug 20 is removed, and the measuring cap 4 is attached again, the measuring cap 4 is closely fitted to the mouth tube portion 7, and the state shown in FIG. It becomes.

  Next, as shown in FIG. 3, when the body portion 5 of the outer container 2 is squeezed, the internal pressure of the inner container 3 increases, and as a result, the first check valve 18 opens and the liquid is poured out through the liquid introduction pipe 11. It flows into the tube 14 and is poured out from the open end into a space (measuring part) 21 defined by the measuring cylinder part 12 and the bottom part 13. At this time, when the liquid is poured out vigorously, the liquid is poured out upward and laterally from the pouring pipe 14, but the liquid strikes the top lower surface 15a and the scattering prevention portion 15b of the lid portion 15 and changes the flow direction. It can be changed downward. As a result, it is possible to prevent the foaming of the liquid and the scattering adhesion to the measuring cylinder portion 12, so that it is easy to check the position of the liquid surface during the measurement. When the squeeze is released and the force pressing the body portion 5 is removed, the outer container 2 is restored to the original shape shown in FIG. 2, so that the internal pressure is reduced and the first check valve 18 is closed. As a result, air is prevented from flowing into the inner container 3. At this time, a negative pressure is generated in the internal space between the outer container 2 and the inner container 3, but the second check valve 19 is opened because the measuring cap 4 and the mouth tube portion 7 are closely fitted. Outside air flows from the intake hole 17 and is introduced into the internal space through the vent hole 8. The second check valve 19 is closed when the outer container 2 is squeezed, and the already introduced air can be sealed in the internal space between the outer container 2 and the inner container 3. Therefore, when squeezing, this sealed air becomes a transmission medium for the force applied to the body portion 5 of the outer container 2 and immediately presses the inner container 3 to reduce its volume. Dispensing takes place quickly.

  As shown in FIG. 4, the liquid poured out into the measuring unit 21 is discharged to the outside from the liquid discharge port 16 of the lid unit 15 by tilting the measuring and dispensing container 1. In addition, when it is not necessary to measure the liquid, as shown in FIG. 5, the liquid is continuously discharged by squeezing the body 5 of the outer container 2 with the weighing-out container 1 tilted. You can also. Even when used in this manner, the first check valve 18 is closed at the same time as the pressing of the body portion 5 is stopped, and the inflow of air into the inner container 3 is prevented.

  Therefore, in the metering and dispensing container of the present invention, the liquid is poured into the metering cap 4 by the squeeze of the outer container 2, so that the metering is easy. Regardless of the mode of use, the contact between the liquid to be stored and the air is reliably blocked by the first check valve 18, so that the quality of the liquid can be maintained. In addition, since air can be efficiently introduced into the internal space between the outer container 2 and the inner container 3 from the intake hole 17 provided in the measuring cap 4, and the air can be sealed in the inner space, continuous pouring Operation becomes possible.

  From the viewpoint of facilitating the weighing, it is preferable that at least a part of the measuring tube portion 12 is transparent or translucent, and that the liquid level in the measuring portion 21 can be visually confirmed from the outside. More preferably, the measuring cylinder portion 12 is marked or marked.

  In the illustrated embodiment, the first check valve 18 is provided at the lower end of the liquid guide pipe 11, but the position of the first check valve 18 is not limited to this, and the liquid guide pipe 11 is not limited thereto. And any position in the extraction pipe 14. Further, the second check valve 19 is disposed so as to cover the intake hole 17, but may be disposed so as to cover the vent hole 8 in the same manner as that described in Patent Document 2. However, from the viewpoint of simplifying the configuration, as in the illustrated embodiment, the first check valve 18 is disposed in the liquid introduction pipe 11 and the second check valve 19 covers the intake hole 17. It is preferable that the first check valve 18 and the second check valve 19 are integrally formed.

  Next, the weighing and dispensing container according to the second embodiment shown in FIG. 6 will be described. In addition, the same code | symbol is used for the member same as the metering-out container of 1st Embodiment shown in FIGS. 1-5, and the description is abbreviate | omitted.

  In the measurement dispensing container 1 of this embodiment, the measurement cylinder portion 12 is extended to the top lower surface 15a of the lid portion 15, and the extended measurement cylinder portion 12 overlaps with the discharge port 16 of the lid portion 15. As shown in FIG. 12, a discharge hole 22 is provided. Further, below the discharge hole 22, a protrusion 23 that circulates around the measuring cylinder portion 12 is provided, and a concave groove provided in the lid portion 15 is fitted into this, so that the lid portion 15 is placed on the measuring cylinder portion 12. It is configured to be rotatable.

  As in the first embodiment, during transportation and storage, the mouth tube portion 7 of the outer container 2 is sealed with an inner plug 20, and the inner plug 20 is removed during use, as shown in FIG. Next, the measuring cap 4 is closely fitted to the mouth tube portion 7. As shown in FIG. 8, when the body part 5 of the outer container 2 is squeezed, the first check valve 18 is opened, and the liquid is poured into the measuring part 21 through the liquid introduction pipe 11 and the extraction pipe 14. Is issued. When the squeeze is released and the force that is pressing the body portion 5 is removed, the inner container 3 is restored to the original shape shown in FIG. 7, the second check valve 19 is opened, and the outside air passes through the intake hole 17. It flows in and is introduced into the internal space through the vent hole 8.

  In discharging the liquid poured into the measuring unit 21, first, the lid unit 15 is rotated, and the discharge port 16 coincides with the discharge hole 22 of the measuring tube unit 12 as shown by the solid line in FIG. 11. (Open position). When the metering container 1 is tilted at this position, the liquid in the metering unit 21 is discharged to the outside through the discharge hole 22 and the discharge port 16 as shown in FIG. Further, even when there is liquid in the measuring unit 21, the lid unit 15 is rotated, and the position where the discharge port 16 is displaced from the discharge hole 22 of the measuring tube unit 12 (closed position) as shown by the broken line in FIG. By doing so, it is possible to prevent liquid from being discharged even when the metering container 1 is tilted. In order to reliably stop the lid 15 at such an open position and a closed position, positioning means such as vertical ribs can be provided on the measuring cylinder portion 12 and the lid portion 15 although illustration is omitted. In addition, when the measurement of the liquid is not necessary, as shown in FIG. 10, the lid portion 15 is set to the open position, and the body portion 5 of the outer container 2 is squeezed with the weighing-out container 1 tilted. In addition, liquid can be continuously discharged.

  Note that the above description shows only a part of the embodiment of the present invention, and these configurations can be combined with each other or various modifications can be made without departing from the gist of the present invention. . For example, in the above embodiment, two each of the vent hole 8, the intake hole 17, and the liquid discharge port 16 are provided, but it may be one, or three or more. In addition, although the example in which the liquid discharge port 16 is provided on the side surface of the lid portion 15 is shown, this may be provided on the top portion of the lid portion 15. Moreover, it can replace with the sealing part 11a, and can also seal the nozzle part of an outer container by making the outer diameter of the lower part of the liquid introduction pipe | tube 11 substantially the same as the inner diameter of the nozzle part 7.

  As is apparent from the above description, according to the present invention, the dispensing of the liquid content is easy, and the continuous dispensing operation is performed while preventing the contact between the liquid to be stored and the air and maintaining the quality of the liquid. It became possible to provide a weighing and dispensing container that made it possible.
