Description of the Related Art There is known a pouring container (a delamination container) that includes an outer layer body that detachably accommodates an inner layer body and that is configured to pour contents from a pouring cap attached to a mouth portion of the outer layer body. The dispensing container is provided in the outer layer body even if the outer layer body is squeezed (pressed) and the contents are poured out, and then the outer layer body is restored to its original shape after the squeezing is released. Since the outside air is introduced between the inner layer body and the outer layer body through the open hole, and the inner layer body can be maintained in a reduced volume state, the contents inside the inner layer body are separated from the outside air as the contents are poured out. It can suppress that it replaces and can avoid the contact with the contents and external air as much as possible.

  In such a pouring container, a check valve is provided in the pouring path of the pouring cap in order to prevent the outside air from flowing into the inner layer body from the pouring outlet when the squeeze is released. As this check valve, a ball valve type that not only prevents the inflow of outside air but also draws in the contents near the spout when squeezing is released to prevent dripping from the spout is used.

Is provided.

  A ball valve 20 formed in a spherical shape by, for example, a steel material or a resin material is disposed inside the cylindrical portion 17, that is, the dispensing path 18. The ball valve 20 is supported on the outer peripheral surface by four ribs 19, guided along the ribs 19, and movable in the axial direction along the extraction path 18. Since the ball valve 20 is guided and moved by the rib 19 as described above, the ball valve 20 can be reliably moved in the axial direction in the pouring path 18 and the contents are passed through between the adjacent ribs 19. Can be efficiently poured out through the pouring path 18. The number of ribs 19 is not limited to four, and an arbitrary number can be provided.

  As shown in FIG. 2, when the pouring container 1 is in a standing posture with the pouring cap 3 up, the ball valve 20 moves downward in the pouring path 18 due to its own weight, and is placed on the inclined wall 17a serving as a valve seat. The abutment path 18 is closed by contacting the entire circumference, and the accommodating portion 4a and the spout 9 are not connected. On the other hand, when the pouring container 1 is tilted by 90 degrees or more with respect to the standing posture, or when the body portion 5b of the outer layer body 5 is squeezed and the contents are pumped from the housing portion 4a to the pouring path 18, the contents in FIG. As indicated by a two-dot chain line, the ball valve 20 moves away from the inclined wall 17a to a position where the ball valve 20 is held by the projection 19a to be retained. As a result, the ball valve 20 is opened, and the accommodating portion 4a and the spout 9 are communicated with each other via a gap between adjacent ribs 19 of the pour channel 18. Thus, the ball valve 20 is an open position where the contents flow from the accommodating portion 4a of the inner layer body 4 toward the spout 9 of the spout cap 3 away from the inclined wall 17a which is a valve seat, and the valve seat. It functions as a check valve that contacts the inclined wall 17a and moves to a closed position that prevents the flow of contents and outside air from the spout 9 toward the accommodating portion 4a to open and close the spout passage 18.

  A valve unit 21 formed of, for example, synthetic resin, rubber, elastomer, or the like is mounted in the space between the pouring cap 3 and the pouring tap 12. The valve unit 21 has a cylindrical holding portion 21a. One end of the holding portion 21a is fitted in an annular groove 13a formed coaxially with the tubular portion 17 on the upper surface of the main body portion 13 of the spout 12 and the other end in the axial direction is a spout cap. 3 is fitted in an annular groove 8b formed coaxially with the annular groove 13a on the lower surface of the top wall 8 and fixed between the dispensing cap 3 and the dispensing plug 12. The space between the pouring cap 3 and the pouring tap 12 is partitioned by the holding portion 21a, and the pouring path 18 is communicated with the pouring port 9 through the space inside the holding portion 21a.

  A plate-like valve 21b as a lift valve formed in a disk shape coaxial with the holding portion 21a is provided on the inner side in the radial direction of the holding portion 21a. The outer peripheral edge of the plate-like valve 21b is connected to the inner peripheral surface of the holding portion 21a by three elastically deformable connecting pieces 21c (only two are shown in the figure), and due to the elastic deformation of these connecting pieces 21c The plate-like valve 21b is movable in the axial direction (vertical direction) with respect to the holding portion 21a. When the body portion 5b of the outer layer body 5 is in a natural state where the plate-like valve 21b is not squeezed, the plate-like valve 21b is disposed at the opening end facing the spout 9 side of the tubular portion 17 and faces the spout 9 of the spout passage 18. The outlet 17c that opens is closed. On the other hand, when the body portion 5b of the outer layer body 5 is squeezed and the contents inside the accommodating portion 4a are pumped to the extraction passage 18, the plate-like valve 21b is elastically deformed in the connecting piece 21c while the axial direction of the holding portion 21a. , And move upward away from the opening end of the cylindrical portion 17 to open the outlet 17c of the pouring path 18. Thus, the plate-like valve 21b allows the contents to flow from the container 4a toward the spout 9 and the flow of the discharge passage 18 so as to prevent the flow of contents and outside air from the spout 9 toward the container 4a. It functions as a check valve that opens and closes the outlet 17c. Note that the connecting piece 21c is not limited to the above-described configuration, and may have various shapes as long as it can be elastically deformed between the holding portion 21a and the plate valve 21b, and the number of the connecting pieces 21c is arbitrarily set. Can do.

  In the pouring container 1 configured as described above, the pouring path 18 is closed by the ball valve 20 and the plate valve 21b in the standing posture shown in FIG. 18 can be improved and the contact of the contents accommodated in the accommodating portion 4a of the inner layer body 4 with the outside air can be reliably prevented.

  On the other hand, when the body portion 5b of the outer layer body 5 is squeezed while the pouring container 1 is tilted, the ball valve 20 moves to the position indicated by the two-dot chain line in FIG. Since the plate valve 21b is opened by the pressure of the pumped contents, the contents stored in the storage portion 4a of the inner layer body 4 are poured out from the upper opening 4b of the inner layer body 4 through the pouring path 18 of the pouring tap 12. It can be poured out from the spout 9 of the cap 3. At this time, if the body portion 5b is squeezed while closing the opening 6 provided in the body portion 5b of the outer layer body 5 with a finger, air is sealed between the inner layer body 4 and the outer layer body 5, and this sealing is performed. Since the deformation of the body portion 5b can be transmitted to the inner layer body 4 through the air layer, the amount of squeeze of the body portion 5b can be reduced and the pouring operation can be easily performed.

  In this way, an opening 6 for introducing outside air between the inner layer body 4 and the outer layer body 5 is provided in the body portion 5b of the outer layer body 5, and this is closed with a finger to squeeze the body portion 5b. By adopting such a configuration, it is not necessary to provide a check valve in the opening 6, and the configuration of the dispensing container 1 can be simplified and its cost can be reduced.

  After the contents are poured out, when the pouring container 1 is returned to the original standing posture and the squeeze of the body 5b of the outer layer body 5 is released, the plate valve 21b returns to the closed state and the outlet 17c of the pouring passage 18 Is closed by the plate valve 21b, and the ball valve 20 is moved to the position indicated by the solid line in FIG.

  At this time, when the squeeze of the body portion 5b of the outer layer body 5 is released, the body portion 5b of the outer layer body 5 is restored to the original shape, but the discharge path 18 is blocked by the ball valve 20 and the plate valve 21b, By introducing outside air between the outer layer body 5 and the inner layer body 4 from the opening 6 of the outer layer body 5, the inner layer body 4 can be maintained in a reduced volume state. Thereby, it can suppress that the content inside the inner-layer body 4 is substituted with external air with the extraction of the content, and can avoid contact with a content and external air as much as possible.

  Further, as the ball valve 20 moves downward toward the inclined wall 17a, the contents near the tip of the spout 9 are drawn toward the side of the spout 18 (suck back). It is possible to effectively prevent liquid dripping from. It is to be noted that the ball valve 20 can be designed to move toward the position where the pouring path 18 is closed before the plate valve 21b is closed by adjusting the elastic force of the connecting piece 21c, or the plate valve 21b and the outlet port. Even after a liquid flow path (groove, embossing, etc.) is provided on the sealing surface with 17c and the plate valve 21b closes the outflow port 17c, the contents are discharged through the liquid flow path through the liquid flow path 18 by the movement of the ball valve 20. It is possible to enhance the effect of the suck back described above.

  Thus, in the pouring container 1 of the present invention, two check valves, the ball valve 20 and the plate valve 21b, are provided as check valves for opening and closing the pouring passage 18 provided in the pouring tap 12. Therefore, after the pouring, the ball valve 20 moves to draw the contents near the spout 9 and prevent dripping from the spout 9, while preventing the outside air from flowing into the inner layer body 4. can do. For example, when the ball valve 20 cannot quickly close the pouring path 18 such as when the squeeze of the body portion 5b of the outer layer body 5 is released after pouring and the pouring container 1 is then returned to the standing posture. Even if it exists, when the squeeze of the trunk | drum 5b is cancelled | released, the pouring path 18 can be obstruct | occluded rapidly by the plate-shaped valve 21b, and the inflow of the external air to the inside of the inner layer body 4 can be prevented reliably. In addition, even if the pouring container 1 is carried by hand before and after the pouring operation, the posture of the pouring container 1 changes, and the ball valve 20 moves unexpectedly in the pouring passage 18 and is in an open state. 18 can be maintained in the closed state by the plate-like valve 21b to prevent the outside air from flowing into the inner layer body 4.

The communication hole 22 opens to the outside of the pouring cap 3 at the side of the stepped portion 8 a of the top wall 8 and between the pouring cap 3 and the pouring tap 12 on the radially outer side of the holding portion 21 a of the valve unit 21. When the overcap 10 is opened, the outside world can communicate with the inside of the pouring cap 3. In addition, a relay hole 23 is provided in the boundary portion between the main body portion 13 and the spacer portion 14 of the spout 12, and a pair of slits that cut the male screw portion 5 c in the vertical direction in the mouth portion 5 a of the outer layer body 5. 24 is provided. On the other hand, a large-diameter portion 5d larger in diameter than the mouth portion 5a is integrally provided in a portion between the mouth portion 5a and the body portion 5b of the outer layer body 5, and the inner peripheral surface of the mounting cylinder portion 7 of the dispensing cap 3 Is in airtight contact with the outer peripheral surface of the large diameter portion 5d. As a result, the opening end (lower end) of the mounting cylinder portion 7 of the dispensing cap 3 is closed, and the opening 6 provided in the mouth portion 5a is exposed to the outside only through the slit 24, the relay hole 23, and the communication hole 22.

  When the dispensing of the contents is completed and the squeeze of the body portion 5b of the outer layer body 5 is released, the body portion 5b of the outer layer body 5 is restored to its original shape, and the space between the inner layer body 4 and the outer layer body 5 is reduced. A negative pressure is generated, and the outside air pushes down the communication hole check valve 21 e and is introduced from the communication hole 22 between the inner layer body 4 and the outer layer body 5 through the relay hole 23, the slit 24 and the opening 6. Thereby, only the outer layer body 5 can be restored to its original shape, and the inner layer body 4 can be maintained in a reduced volume state. Further, since the check hole valve 21e prevents the outflow of air from the opening 6 toward the outside, when the contents are poured out by squeezing the body 5b of the outer layer body 5, the communication hole The air can be sealed between the outer layer body 5 and the inner layer body 4 by the check valve. Accordingly, the deformation of the body portion 5b can be transmitted to the inner layer body 4 through the sealed air layer to reduce the amount of squeeze of the body portion 5b necessary for the pouring, thereby facilitating the pouring work.
