Further, a through hole 18a through which the outside air from the communication hole 16a to the outside air introduction port 5b passes is formed in the outer edge portion of the partition wall 18 (the lower portion of the annular wall 20).

  A pipe 23 is connected to the first flow port 21 and a first check valve 24 is provided.

  The first check valve 24 includes a cylindrical body 25 that is provided integrally with the partition wall 18 and protrudes from the lower surface of the partition wall 18 toward the bottom 8 side, and a valve body 26 that is disposed inside the cylindrical body 25. Have. The cylindrical body 25 includes a main body portion 25a having a constant inner diameter, and a reduced diameter portion 25b having a smaller diameter than the main body portion 25a integrally connected to the lower end of the main body portion 25a through a portion that decreases in diameter downward. The upper end is connected to the opening of the first flow port 21.

  The valve body 26 is formed in a spherical shape (spherical) having a diameter smaller than the inner diameter of the main body portion 25a and larger than the inner diameter of the reduced diameter portion 25b, for example, by a steel material or a resin material, and is disposed inside the main body portion 25a. Thus, it is movable along the axial direction of the main body portion 25a between a closed position contacting the upper end of the reduced diameter portion 25b and an open position away from the reduced diameter portion 25b. When the valve body 26 is in the open position, a gap is formed between the inner peripheral surface of the main body 25a and the outer peripheral surface of the valve body 26, and the contents can be distributed through the gap.

  For example, the pipe 23 made of synthetic resin has a cylindrical shape having an outer diameter equivalent to the outer diameter of the main body portion 25a and an inner diameter equivalent to the outer diameter of the reduced diameter portion 25b. It is fitted and fixed to the outer peripheral surface of the reduced diameter portion 25 b and is connected to the first flow port 21 via the first check valve 24.

  As shown in FIG. 1, the pipe 23 is straight along the central axis O of the outer layer body 2 from the upper end portion connected to the first flow port 21 via the first check valve 24. The linear portion 23a extending toward the bottom portion 8 and the lower end of the linear portion 23a are integrally connected to the central axis O of the outer layer body 2 and directed in the direction opposite to the direction in which the tip opening 17c of the dispensing nozzle 17 faces. And an inclined portion 23b extending in an inclined manner. That is, the pipe 23 has a shape that is bent in a dogleg shape toward the opposite side to the pouring nozzle 17 at an intermediate portion in the longitudinal direction. Thereby, in FIG. 1, the tip opening 17 c of the pouring nozzle 17 faces the left side, whereas the lower end 23 c of the inclined portion 23 b of the pipe 23 is It is directed in a direction inclined to the side opposite to the tip opening 17c, and is shifted from the center axis O of the outer layer body 2 on the opposite side to the direction in which the tip opening 17c of the dispensing nozzle 17 faces.

  A lower end 23 c of the inclined portion 23 b of the pipe 23 is opened on the bottom 8 side inside the accommodation space M. The lower end 23c of the pipe 23 is positioned such that the lower end 23c of the pipe 23 is accommodated in the accommodating space M when the pouring container 1 is tilted so that the tip opening 17c of the pouring nozzle 17 faces downward. It is set to be located inside the first liquid L1. Therefore, when the dispensing container 1 is tilted so that the tip opening 17c of the dispensing nozzle 17 faces downward, out of the separated liquid contents housed in the housing space M, the container 8 is moved to the bottom 8 side. The first liquid L1 to be stored separately can be taken from the lower end 23c of the pipe 23 and guided toward the first circulation port 21 through the pipe 23. That is, the pipe 23 is connected to the first flow port 21 so that the pouring container 1 is tilted so that the tip opening 17c of the pouring nozzle 17 faces downward to pour out the separated liquid content. When pouring from the nozzle 17, the first liquid L <b> 1 accommodated on the bottom 8 side of the accommodating space M can be circulated to the pouring nozzle 17 through the pipe 23 and the first circulation port 21.

  As shown in FIG. 2, the pipe 23 may be configured such that a guard member 23d is attached to the lower end 23c of the inclined portion 23b. The guard member 23d has a cylindrical shape that is fitted and fixed to the lower end 23c of the inclined portion 23b, and a plurality of slits 23e are provided on the outer peripheral wall thereof. By attaching the guard member 23d to the lower end 23c of the inclined portion 23b, the lower end 23c of the pipe 23 is prevented from being sealed by the inner layer body 3 that has undergone volume reduction deformation.

  As shown in FIG. 2, the second circulation port 22 is provided in the partition wall 18 adjacent to the outside of the cylindrical body 25, and the tip opening 17 c of the dispensing nozzle 17 faces downward from the dispensing container 1. The second liquid L2 accommodated on the side of the mouth portion 5 of the accommodation space M is circulated toward the extraction nozzle 17 when the separated liquid content is extracted from the extraction nozzle 17 by being tilted like this. be able to.

  In the first check valve 24 described above, the valve body 26 moves from the closed position to the open position with respect to the flow of contents from the pipe 23 through the first flow port 21 to the discharge nozzle 17. The valve body 26 operates to move from the open position to the closed position and to prevent the flow of contents from the discharge nozzle 17 through the first flow port 21 to the pipe 23. . Further, the first check valve 24 reaches the lower end position where the valve body 26 comes into contact with the reduced diameter portion 25b by its own weight when the dispensing container 1 is returned to the upright posture after the contents are poured out. By moving, the contents remaining inside the pouring nozzle 17 can be sucked toward the accommodation space M. By such a suck back function of the first check valve 24, it is possible to prevent the contents from dripping from the tip opening 17 c of the dispensing nozzle 17. As will be described later, the first flow port 21 is configured such that the backflow of contents from the side of the dispensing nozzle 17 toward the side of the accommodation space M is also regulated by the second check valve 28. Therefore, the valve body 26 may not be provided. Moreover, when it is set as the structure which provided the valve body 26, depending on the 2nd non-return valve 28, the backflow of the content toward the accommodation space M side from the side of the extraction nozzle 17 in the 1st distribution port 21 may be carried out. It can also be set as the structure which is not controlled.

  As shown in FIG. 2, the valve member 13 includes a cylindrical holding portion 27, a second check valve 28 provided inside the holding portion 27, and an intake check valve 29 provided outside the holding portion 27. And are integrally formed. The second check valve 28 and the intake check valve 29 may be formed as separate members.

  The holding portion 27 is fitted and held between the partition wall 18 of the inner plug 12 and the top wall 16 of the dispensing cap 11. The inside of the holding part 27 is a space through which the contents flowing in through the first circulation port 21 and the second circulation port 22 can pass, and the outside of the holding part 27 is from the communication hole 16a to the outside air introduction port 5b. It is an air flow path that allows air to pass through.

  The second check valve 28 is disposed across the opening of the first flow port 21 and the opening of the second flow port 22 and opens and closes the opening of the first flow port 21 and the opening of the second flow port 22. The flow of contents from the storage space M through the first flow port 21 or the second flow port 22 toward the discharge nozzle 17 is allowed, and the first flow port 21 or the second flow from the discharge nozzle 17. It operates so as to block the flow (back flow) of the contents toward the accommodation space M through the mouth 22. In the present embodiment, the thin check-like second check valve 28 is a three-point valve that moves up and down in the axial direction in accordance with the pressure of the contents from the accommodation space M toward the dispensing nozzle 17. (A valve connected to the inner peripheral surface of the holding portion 27 with three elastically deformable legs), and the first flow port 21 and the second flow port 22 are provided only when the contents are poured out. It is designed to be opened. The second check valve 28 is not limited to a three-point valve, and is connected to the inner peripheral surface of the holding portion 27 by a valve connected by two or less legs or by four or more legs. You may comprise with a valve.

  The intake check valve 29 is formed of an annular piece extending radially outward from the outer peripheral surface of the holding portion 27, and the outer edge thereof is elastically in contact with the lower surface of the top wall 16 on the outer peripheral side of the communication hole 16a. In this manner, the intake check valve 29 is provided in the air flow path that connects the communication hole 16a and the outside air introduction port 5b, and allows the flow of air from the communication hole 16a toward the outside air introduction port 5b. An air flow (back flow) from the port 5b toward the communication hole 16a is blocked.

  The lid 14 is detachably attached to the tip of the inclined portion 17b of the pouring nozzle 17 by screw connection, and closes the tip opening 17c of the pouring nozzle 17. When the contents are poured out, the lid body 14 is removed from the pouring nozzle 17.

  When the contents are poured out from the pouring container 1 having the above-described configuration, first, the lid body 14 is removed from the pouring nozzle 17 to open the tip opening 17c. Next, as shown in FIG. 3, the dispensing container 1 is tilted so that the tip opening 17 c of the dispensing nozzle 17 faces downward. When the dispensing container 1 is tilted so that the tip opening 17c of the dispensing nozzle 17 faces downward, the first liquid L1 having a low specific gravity is on the side of the bottom 8, and the second liquid L2 having a high specific gravity is on the side of the mouth 5. Located in.

  When the body portion 7 is squeezed in this state, the inner layer body 3 is pressurized, and the first liquid L1 on the bottom 8 side of the accommodation space M is taken into the pipe 23 from the lower end 23c of the pipe 23, and the first flow is made. It flows toward the mouth 21. When the first liquid L1 flows toward the first flow port 21, the valve body 26 moves from the closed position to the open position by its own weight or liquid pressure, the first check valve 24 is opened, and the first liquid L1 is It flows through the first distribution port 21 toward the pouring nozzle 17. Further, when the inner layer body 3 is pressurized, the second check valve 28 is opened, and the second liquid L2 on the side of the mouth portion 5 of the accommodation space M passes through the second circulation port 22 and the dispensing nozzle 17. Circulate towards

  The first liquid L1 that flows from the first flow port 21 toward the pouring nozzle 17 and the second liquid L2 that flows from the second flow port 22 toward the pouring nozzle 17 are mixed with each other inside the pouring nozzle 17. The The contents composed of the first liquid L1 and the second liquid L2 mixed at the intended mixing ratio in this way are poured out from the tip opening 17c through the pouring nozzle 17 to the outside.

  Here, in the pouring container 1 of the present embodiment, the tip opening 17c of the pouring nozzle 17 is directed in a direction inclined with respect to the direction of the central axis O of the outer layer body 2, and therefore the contents are poured out. When the dispensing container 1 for tilting is tilted, the tip opening 17c of the dispensing nozzle 17 is directed downward, and the double container 4 is inclined so as to be inclined (position shown in FIG. 3). The direction of the outlet nozzle 17 and the inclination angle of the dispensing container 1 are limited.

  On the other hand, the lower end 23c of the pipe 23 is directed in a direction inclined to the opposite side of the tip opening 17c of the pouring nozzle 17 with respect to the central axis O of the outer layer body 2, so that the pouring container 1 is poured out. When the tip opening 17c of the nozzle 17 is tilted so as to face downward, the lower end 23c of the pipe 23 faces substantially upward on the bottom 8 side. Thereby, even when the filling ratio of the first liquid L1 having a small specific gravity is extremely small as compared with the second liquid L2 having a large specific gravity, the lower end 23c of the pipe 23 is the bottom of the double container 4 inclined obliquely. On the side of 8, the water surface is surely disposed inside the first liquid L <b> 1 having a low specific gravity and positioned so that the water surface is inclined with respect to the bottom 8. Therefore, when pouring the contents by tilting the pouring container 1 so that the tip opening 17c of the pouring nozzle 17 faces downward, the lower end of the pipe 23 is fed into the air A of the head space contained in the housing space M. It is possible to suppress the exposure of the liquid 23c and to discharge the first liquid L1 and the second liquid L2 from the tip opening 17c of the discharge nozzle 17 to the outside at a predetermined mixing ratio.

  Thus, according to the pouring container 1 of the present invention, no hand-shaking operation is required, and the pouring container 1 is tilted so that the tip opening 17c of the pouring nozzle 17 faces downward, and the body portion 7 is squeezed. The separated liquid content can be poured out at a desired mixing ratio by a simple operation.

  When the outer layer body 2 is restored to its original shape by releasing the squeeze of the body portion 7, the communication hole 16a and the outside air introduction port 5b are changed as the space between the inner layer body 3 and the outer layer body 2 becomes a negative pressure state. Thus, outside air is introduced between the inner layer body 3 and the outer layer body 2. Further, during this time, the first check valve 24 and the second check valve 28 close the first flow port 21 and the second flow port 22, so that outside air enters the inside of the accommodation space M through the discharge nozzle 17. There is no. Accordingly, the outer layer body 2 can be restored to its original shape while reducing the volume of the inner layer body 3 without introducing outside air into the accommodation space M. Therefore, it is possible to prevent outside air from being introduced into the accommodation space M as the contents are poured out, and to suppress deterioration or deterioration of the contents.

  As described above, the first liquid L1 and the second liquid L2 can be poured out at a predetermined mixing ratio, and since the air does not enter the storage space M, the contents are poured out. Even if the remaining amount decreases, the first liquid L1 and the second liquid L2 always exist in the accommodation space M at a constant volume ratio. Moreover, since the lower end 23c of the pipe 23 is always disposed on the bottom 8 side, the content can be stably poured out at the expected mixing ratio even when the remaining amount of the content is reduced.

  The mixing ratio of the first liquid L1 and the second liquid L2 is the size of the first flow port 21 and the second flow port 22, the inner diameter of the pipe 23, the gap between the main body 25a and the valve body 26, the second reverse A desired mixing ratio can be set by variously changing the opening degree of the stop valve 28 and the like.
