The position of the inflow port 24a of the pipe 24 may be set so as to be located inside the first liquid L1 housed in the filling space S when the pouring container 1 is in the inverted position. In order to more reliably position the inflow port 24a inside the first liquid L1, it is preferable to arrange the inflow port 24a in the vicinity of the bottom portion 8.

On the other hand, the second distribution port 22 is provided on the partition wall 18 adjacent to the tubular body 23, and is filled when the separated liquid content is poured out from the pouring port 17a with the pouring container 1 in an inverted posture. The second liquid L2, which is on the side of the mouth portion 5 of the space S, can be circulated toward the spout 17a.

As described above, the pouring container 1 is one of the separated liquid contents contained in the filling space S when pouring out with the pouring container 1 in the inverted posture. The first liquid L1) is circulated from the bottom 8 side toward the spout 17a, and the other liquid (second liquid L2) is circulated from the mouth 5 side toward the spout 17a, and these are mixed. It is designed to be discharged to the outside.

As shown in FIG. 2, the valve member 13 is formed by integrally forming a check valve 25 for injection and a check valve 26 for intake air. The check valve 25 for injection and the check valve 26 for intake air may be formed as separate members.

The check valve 25 for injection includes a cylindrical holding portion 25a, a valve body 25b provided inside the holding portion 25a, and a leg portion 25c connecting the valve body 25b and the holding portion 25a. Although only one leg portion 25c is shown in FIG. 2, three leg portions 25c are provided between the valve body 25b and the holding portion 25a so as to be arranged at equal intervals in the circumferential direction.

The valve body 25b is formed in a plate shape (disk shape), and is in contact with the upper surface of the partition wall 18 of the inner plug 12 to cover the first flow port 21 and the second flow port 22.

The holding portion 25a is formed in a cylindrical shape that surrounds the outer circumference of the valve body 25b at a predetermined interval, and the lower end thereof is fitted and fixed to the partition wall 18 and attached to the inner plug 12.

The pouring flow path P1 that communicates is formed as a section. Further, the space outside the holding portion 25a inside the cap assembly 6 is an air flow path P2 through which air can pass between the communication hole 16a and the through hole 5b.

The three legs 25c are formed in a crank shape in which the connecting portion with the valve body 25b is displaced in the circumferential direction with respect to the connecting portion with the holding portion 25a, and between the valve body 25b and the holding portion 25a, respectively. It is elastically deformable in the vertical direction. As each leg portion 25c is elastically deformed in the vertical direction, the valve body 25b has a closing position for simultaneously closing the first distribution port 21 and the second distribution port 22, and a first distribution port 21 and a second distribution port 22. It is movable between the open position and the open position that opens at the same time.

When the valve body 25b is in the closed position, the flow of contents from the spout 17a to the filling space S through the first flow port 21 and the pipe 24 and the direct filling from the spout 17a through the second flow port 22. Both the flow of contents towards space S is blocked. On the other hand, when the valve body 25b is in the open position, the flow of the contents from the filling space S through the pipe 24 and the first distribution port 21 to the spout 17a and directly from the filling space S through the second distribution port 22. Both flow of contents towards the spout 17a is allowed. That is, the check valve 25 for pouring is a flow of contents from the filling space S through the pipe 24 and the first distribution port 21 to the spout 17a, and directly from the filling space S through the second distribution port 22. Simultaneously allow the flow of contents toward the spout 17a, the flow of contents from the spout 17a through the first distribution port 21 and the pipe 24 to the filling space S, and the flow of the contents from the spout 17a to the second distribution port 22. It operates to simultaneously block the flow of contents through and directly to the filling space S.

In the present embodiment, the check valve 25 for pouring is configured as a three-point valve in which the valve body 25b is connected to the holding portion 25a by the three leg portions 25c, but for pouring. The check valve 25 is not limited to the three-point valve, and may be configured as, for example, a two-point valve or a one-point valve in which the valve body 25b is connected to the holding portion 25a by two or less legs 25c, or the valve body 25b. May be connected to the holding portion 25a with four or more leg portions 25c.

The intake check valve 26 is integrally provided with the injection check valve 25. More specifically, the intake check valve 26 is formed in an annular film shape extending radially outward from the outer peripheral surface of the holding portion 25a, and the outer edge thereof is on the outer peripheral side of the communication hole 16a. It is designed to elastically contact the lower surface of the wall 16. The check valve 26 for intake air is provided in the air flow path P2 inside the cap assembly 6 to allow the air flow from the communication hole 16a to the through hole 5b, and is directed from the communication hole 5b to the communication hole 16a. It works to block the flow of air.

In the pouring container 1 of the present embodiment, the intake check valve 26 is provided integrally with the pouring check valve 25, so that the intake check valve 26 is different from the pouring check valve 25. The number of parts can be reduced as compared with the case where the container 1 is provided separately, and the manufacturing cost of the dispensing container 1 can be reduced.

The lid 14 has a peripheral wall 31 connected to the outer peripheral wall 15 of the dispensing cap 11 via a hinge 30, a top wall 32 covering the upper portion of the peripheral wall 31, and a tip of the dispensing cylinder 17 hanging from the top wall 32. It is provided with a seal cylinder 33 that movably closes (seals) the spout 17a of the above. The lid body 14 may be attached to the ejection cap 11 by screw connection without providing the hinge 30.

In the pouring container 1 having the above configuration, as shown in FIG. 3, the lid 14 is opened to put the pouring container 1 in an inclined or inverted posture, and the body 7 is squeezed (pressed) to dispense the contents. be able to.

That is, when the pouring container 1 is tilted or inverted, the first liquid L1, which has a lighter specific gravity than the second liquid L2, is located on the bottom 8 side of the double container 4, and has a higher specific gravity than the first liquid L1. The heavy second liquid L2 is located on the side of the mouth 5, and when the body 7 of the outer layer 2 is squeezed and the inner layer 3 is pressurized, the second liquid L2 on the bottom 8 side of the filling space S The first liquid L1 is taken into the pipe 24 from the inflow port 24a and flows toward the first flow port 21, and the second liquid L2 on the side of the mouth portion 5 of the filling space S flows toward the second flow port 22. Then, the valve body 25b moves from the closed position to the open position due to the hydraulic pressure of these contents, the check valve 25 for pouring is opened, and the first liquid L1 passes through the first distribution port 21 and the spout 17a. The content is composed of the first liquid L1 and the second liquid L2, which are circulated toward the spout 17a through the second flow port 22 and are mixed at the desired mixing ratio. An object is poured out from the spout 17a through the pouring cylinder 17.

As described above, according to the pouring container 1 of the present embodiment, the inner plug 12 is provided with the first distribution port 21 and the second distribution port 22, and the pipe 24 is connected to the first distribution port 21. As a result, the contents are introduced from the bottom 8 side and the mouth 5 side of the pouring container 1, so that even if the separated liquid contents are contained as the contents, the pouring container 1 is used. The separated liquid contents can be poured out from the spout 17a at the desired mixing ratio by a simple operation of squeezing the body portion 7 without a hand-waving operation.

The mixing ratio of the first liquid L1 and the second liquid L2 is set to a desired mixing ratio by variously changing the sizes of the first distribution port 21 and the second distribution port 22, the inner diameter of the pipe 24, and the like. Can be done.

Further, in the pouring container 1 of the present embodiment, the pouring check valve 25 is provided with a valve body 25b that simultaneously closes the first distribution port 21 and the second distribution port 22. The first liquid L1 flowing from the distribution port 21 toward the spout 17a and the second liquid L2 flowing from the second flow port 22 toward the spout 17a collide with each other at the valve body 25b and are stirred. In this way, it can be made to flow toward the spout 17a in a uniformly mixed state. As a result, the first liquid L1 and the second liquid L2 uniformly mix the contents of the separated liquid having the desired mixing ratio without manually shaking the pouring container 1 or providing a member for stirring. It can be poured out as it is.

Further, in the pouring container 1 of the present embodiment, the check valve 25 for pouring is configured such that the valve body 25b is connected to the holding portion 25a by a plurality of leg portions 25c, and the check valve 25 is formed from the side of the filling space S. Since the valve body 25b moves up and down in response to the pressure of the contents toward the spout 17a to function as a check valve, the valve body 25b connects the first flow port 21 and the second flow port 22. At the same time, it can be opened and closed with an even opening. Therefore, it is possible to always pour out the first liquid L1 and the second liquid L2 from the filling space S through the first flow port 21 and the second flow port 22 at a constant ratio, and the contents of the separated liquid can be more accurately dispensed. It can be dispensed at the desired mixing ratio.

Further, in the pouring container 1 of the present embodiment, the check valve 25 for pouring is configured such that the valve body 25b is connected to the holding portion 25a by a plurality of leg portions 25c. It can be opened and closed with a uniform opening over the entire circumference. As a result, the first liquid L1 flowing out from the first distribution port 21 and the second liquid L2 flowing out from the second distribution port 22 are mixed more evenly in the portion of the valve body 25b, so that the contents of the separated liquid are mixed. The product can be poured out in a more accurate and desired mixing ratio.

Further, in the pouring container 1 of the present embodiment, the check valve 25 for pouring is configured to include a valve body 25b that simultaneously closes the first distribution port 21 and the second distribution port 22. Compared with the case where the check valves are separately provided in the distribution port 21 and the second distribution port 22, the number of parts can be reduced and the manufacturing cost of the dispensing container 1 can be reduced.

When the squeeze of the body 7 is released after the pouring of the contents is completed, the outer layer 2 tries to restore the original shape, and as a result, the inner layer 3 and the outer layer are reduced in volume and deformed by the pouring of the contents. The space between the body 2 and the body 2 is in a negative pressure state. At this time, the negative pressure causes air to be introduced between the inner layer body 3 and the outer layer body 2 through the communication hole 16a, the through hole 18a, the vertical groove 5c, and the through hole 5b. Only the outer layer 2 can be restored to its original shape while being reduced in volume and deformed. Further, when the squeeze of the body portion 7 is released, the valve body 25b returns to the closed position by the elastic force of the leg portion 25c, and the first flow port 21 and the second flow port 22 are liquid-tightly closed by the valve body 25b. Therefore, air does not enter the filling space S.

As described above, the first liquid L1 and the second liquid L2 can be poured out at the desired mixing ratio, and even if the contents are poured out, air does not enter the inside of the filling space S. Therefore, even when the contents are poured out and the remaining amount is reduced, only the first liquid L1 and the second liquid L2 always exist inside the filling space S at a constant volume ratio. become. Therefore, when the pouring container 1 is in the tilted or inverted posture, the inflow port 24a at the lower end of the pipe 24 is always located inside the first liquid L1, and when the remaining amount of the contents decreases. In addition, the contents can be continuously poured out at the desired mixing ratio.

Further, in the pouring container 1 of the present embodiment, since the check valve 26 for intake air is provided in the air flow path P2 of the cap assembly 6, after pouring out the contents, the body portion 7 is further moved. When squeezing and pouring out the contents, the intake check valve 26 can prevent the air in the space between the outer layer 2 and the inner layer 3 from flowing out to the outside. As a result, when the outer layer 2 is squeezed, the inner layer 3 can be effectively pressed through the air in the space between the outer layer 2 and the inner layer 3, and the contents from the pouring container 1 can be pressed. The operation of pouring out an object can be facilitated.

FIG. 4 is a cross-sectional view of a modified example of the pouring container shown in FIG. In FIG. 4, the members corresponding to the above-mentioned members are designated by the same reference numerals.

The pouring container 1 of the modified example shown in FIG. 4 has an elongated nozzle shape in which the pouring cylinder 17 protrudes larger from the top wall 16 and has a constant inner diameter, and the lid 14 is a pouring cylinder. The difference is that it is attached to the tip of 17 by screw connection. With such a configuration, when the contents are dispensed with the pouring container 1 in an inclined posture or an inverted posture, the contents are more accurately directed from the tip of the elongated nozzle-shaped pouring cylinder 17 toward a desired position. You can have things poured out.

Further, in the configuration of the modified example shown in FIG. 4, the pouring cylinder 17 provided on the pouring cap 11 functions as a measuring unit, and the pouring container 1 is squeezed while the pouring container 1 is in the upright posture. It is also possible to have a configuration in which the contents are poured out.

In this case, the inside of the dispensing cylinder 17 is a measuring chamber R having a predetermined capacity, and the inner peripheral surface of the dispensing cylinder 17 has a scale (not shown) indicating, for example, a predetermined amount of capacity inside the measuring chamber R. Is provided. The user can dispense the contents by squeezing the body portion 7 while keeping the dispensing container 1 in the upright posture. When the pouring container 1 is in the upright position, the first liquid L1 having a lighter specific gravity than the second liquid L2 is located on the side of the mouth 5 of the double container 4, and the second liquid has a heavier specific gravity than the first liquid L1. Since L2 is located on the side of the bottom 8, when the body 7 is squeezed, the valve body 25b moves from the closed position to the open position due to the hydraulic pressure of the contents, and the check valve 25 for pouring is opened. , The second liquid L2 flows through the pipe 24 and the first flow port 21 toward the spout 17a, and the first liquid L1 flows through the second flow port 22 toward the spout 17a. The contents composed of the first liquid L1 and the second liquid L2 mixed at the same mixing ratio will be supplied to the pouring cylinder 17. Then, when the content supplied to the dispensing cylinder 17 is supplied to the measuring chamber R until the content reaches a predetermined amount corresponding to the scale provided inside the dispensing cylinder 17, the content is released by releasing the squeeze of the body portion 7. An object can be weighed into a predetermined amount. Even if the squeeze of the body portion 7 is released after the weighing, the valve body 25b is in the closed position and the amount of the contents inside the measuring chamber R is maintained. Then, by tilting the pouring container 1, the weighed contents inside the measuring chamber R can be poured out from the pouring outlet 17a.

In this case, it is preferable that the pouring cap 11 is formed by using, for example, a transparent or translucent synthetic resin material so that the pouring cylinder 17 has a transparent structure. As a result, the amount of the contents inside the measuring chamber R can be easily visually recognized from the outside, and the weighing work can be performed more easily. The dispensing cylinder 17 may be formed separately from the dispensing cap 11 by a transparent material and may be fixed to the dispensing cap 11.

The lid body 14 has a configuration in which a female screw 31a is provided on the inner peripheral surface of the peripheral wall 31, and is screw-coupled to a male screw 17b provided on the outer peripheral surface of the dispensing cylinder 17.

It goes without saying that the present invention is not limited to the above-described embodiment and can be variously modified without departing from the gist thereof.

For example, in the above-described embodiment, a laminated peeling container formed by extrusion blow molding is used as the double container 4, but the present invention is not limited to this, and for example, a substantially test tube shape having a laminated structure in advance is used. A laminated peeling container formed by biaxially stretching blow molding the formed preform may be used, or an individually formed outer layer body (outer container) and an inner layer body (inner container) may be combined. The one having a configuration may be used.

Further, the check valve 25 for dispensing is not limited to the one provided with the holding portion 25a, the valve body 25b and the leg portion 25c, and the first distribution port 21 and the second distribution port 22 can be opened and closed at the same time. If possible, various configurations can be used.

Further, the arrangement of the vertical groove 5c is not essential, and a spiral gap is provided between the female screw portion 15a and the male screw portion 5a formed on the inner surface of the outer peripheral wall 15 of the cap assembly 6, and air is provided through the gap. May be introduced. From the viewpoint of reducing the resistance of the air flow path, it is preferable to provide the vertical groove 5c as shown in the figure.
