In addition to communicating with the path P1, it opens to the upper surface of the upper half 22 inside the connecting cylinder part 42 and communicates with the discharge flow path P2. That is, the communication path 24 constitutes a part of the air flow path P1.

  A pouring hole check valve 50 is disposed in the pouring hole 23 of the inner plug member 20. The check-out valve 50 for the dispensing hole is a so-called ball valve having a cylindrical body 51 integrally provided on the lower surface of the lower half 21 of the inner plug member 20 and a ball 52 arranged inside the cylindrical body 51. It is configured as. The ball 52 has a spherical shape whose diameter is slightly smaller than the inner diameter of the cylindrical body 51, and is movable up and down within the cylindrical body 51. Further, since the diameter of the ball 52 is smaller than the inner diameter of the cylindrical body 51, a gap through which the content liquid L can pass is provided between the inner peripheral surface of the cylindrical body 51 and the outer peripheral surface of the ball 52. A plurality of protrusions 51 a are arranged on the inner peripheral surface of the cylindrical body 51 at intervals in the circumferential direction, and the upper stroke end of the ball 52 is defined by these protrusions 51 a. A reduced-diameter portion 53 whose inner diameter gradually decreases downward is integrally provided at the lower end of the cylindrical body 51, and the ball 52 is in contact with the reduced-diameter portion 53 over the entire circumference, thereby the cylindrical body 51. Is to be blocked. An extension cylinder part 54 is integrally provided at the lower end of the reduced diameter part 53, and the inside of the cylinder body 51 communicates with the internal space of the inner layer body 11 through the extension cylinder part 54.

  The check-out valve 50 for the dispensing hole having such a configuration is formed by the pressure of the content liquid L raised in the inner layer body 11 by squeezing the body portion 10b of the container body 10, or By tilting 90 degrees or more from the upright posture (the posture shown in FIG. 1), the ball 52 moves in the direction away from the reduced diameter portion 53 (upward in FIG. 2) inside the cylindrical body 51. 11, the flow of the content liquid L to the discharge flow path P2 through the extraction hole 23 is permitted. On the other hand, when the squeeze of the body portion 10 b is released or the container body 10 is returned to the upright posture, the ball 52 moves downward inside the cylindrical body 51 and hits the reduced diameter portion 53. The cylinder body 51 is closed in contact with the cylinder body 51 so as to block the flow of the content liquid L (and air) from the discharge flow path P2 to the inside of the inner layer body 11 through the outlet hole 23.

  Further, an air flow path check valve 60 is provided in the air flow path P1. In the case shown in the figure, the air flow path check valve 60 is provided in a portion of the communication passage 24 that constitutes a part of the air flow path P1 and that opens upward inside the connecting cylinder portion 42. The air flow path check valve 60 is arranged on the upper surface of the upper half 22 of the inner plug member 20 and has an annular plate-like valve body 61 that closes the opening of the communication passage 24, and the plate-like valve body 61. It has three crank-shaped connecting arm portions 62 (only two are shown in FIG. 2) connected to the inner peripheral surface of the connecting cylinder portion. The plate-like valve body 61 and the connecting arm portion 62 are each formed of an elastic body such as rubber or elastomer integrally with the connecting cylinder portion 42, and when the connecting arm portion 62 is elastically deformed, the plate-like valve body 61 is It is possible to move from the closed position that closes the opening of the communication path 24 to the open position that leaves the opening and communicates the communication path 24 with the discharge flow path P2. That is, the air flow path check valve 60 is configured as a so-called three-point valve having a plate-like valve body 61 integrally connected to the inner peripheral surface of the connecting cylinder part 42 via the connecting arm part 62. The air flow path check valve 60 allows air to flow from the air flow path P1 to the discharge flow path P2 via the communication path 24, and from the discharge flow path P2 to the air flow path P1 via the communication path 24. Operates to block air flow.

  The air flow check valve 60 is not limited to the three-point valve having the above-described configuration, and may be a check valve having another configuration such as a one-point valve.

  The squeeze discharge container 1 may be configured such that, for example, a throttle portion is provided in the air flow path P1, and the air flow check valve 60 is not provided. Thus, it is possible to reliably prevent the content liquid L and air remaining in the discharge flow path P2 from being introduced into the air chamber 14 through the air flow path P1 and the air holes 13.

  The top wall 33 of the cap 30 is provided with a plurality of outside air introduction holes 35 that allow the air flow path P1 to communicate with the outside of the cap 30. An outside air introduction hole check valve 70 is provided between the top wall portion 33 of the cap 30 and the upper half 22 of the inner plug member 20 so as to be located on the outer peripheral side of the connecting tube portion 42.

Slightly movable. The check valve 70 for outside air introduction hole closes the outside air introduction hole 35 by coming into contact with the lower surface of the top wall portion 33 when the body portion 10b is squeezed to increase the internal pressure of the air passage P1, and the air passage The outflow of air from P1 to the outside of the cap 30 through the outside air introduction hole 35 is prevented. On the other hand, when the squeeze of the body portion 10b is released and the inside of the air flow path P1 becomes negative pressure, the outside air introduction hole 35 is opened, and the outside air is introduced from the outside of the cap 30 to the air flow path P1 through the outside air introduction hole 35. Operates to allow introduction.

  A foam member 80 is provided inside the connecting cylinder portion 42, that is, between the dispensing hole 23 and the discharge flow path P2. As the foaming member 80, for example, a member made of a porous body having a large number of gaps inside such as sponge, felt, sintered body or the like can be used. The liquid L discharged from the discharge hole 23 and the air discharged from the communication passage 24 flow to the discharge flow path P2 through the foaming member 80 and are mixed with each other by the foaming member 80 to efficiently foam. Is foamed.

  A pair of foam regulating members 81 is attached to the inside of the nozzle 40, that is, the discharge flow path P2. Each of the foam regulating members 81 has a configuration in which a mesh 81b is fixed to an end surface of the ring 81a, and is arranged so as to be vertically stacked inside the nozzle 40 in a posture in which the mesh 81b is directed in opposite directions. By providing such a foam regulating member 81, the content liquid L made foamed in the foaming member 80 can be adjusted to finer bubbles.

  The foam regulating member 81 is not limited to the one having the ring 81a and the mesh 81b, but can have various structures according to the type of the content liquid L or the like. Further, the number of the foam regulating members 81 can be variously changed according to the type of the content liquid L, and the foam regulating member 81 can be omitted.

  A switching valve 90 is provided in the air hole 13. The switching valve 90 projects radially outward from the outer peripheral surface of the mouth portion 10 a and is disposed in a space between the mouth portion 10 a and the skirt portion 32 of the cap 30. The switching valve 90 includes an adapter body 91 and a ball 92 as a spherical valve body housed inside the adapter body 91.

  The adapter body 91 includes a cylindrical mounting portion 91a. The mounting portion 91a is inserted into the air hole 13 and is fitted and held in the air hole 13, whereby the adapter body 91 is mounted in the air hole 13 of the mouth portion 10a. An annular protrusion 91b is integrally provided on the outer peripheral surface on the distal end side of the mounting portion 91a, and the mounting portion 91a is air-engaged when the protrusion 91b engages with the inner peripheral surface of the mouth portion 10a. It is prevented from coming off from the hole 13.

  A communication hole 93 is provided in the shaft center of the mounting portion 91 a, and the communication hole 93 communicates with the air chamber 14.

  Further, the adapter body 91 has a main body portion 91c that is integrally connected to the mounting portion 91a. The main body portion 91c is formed in a bottomed cylindrical shape, and is disposed with its axis centered in the vertical direction and the open end directed upward. A ball 92 is accommodated in the internal space of the main body portion 91c, and a communication hole 93 is opened at an intermediate position in the axial direction (intermediate position in the vertical direction) of the internal space. In addition, a tapered reduced diameter seal portion 91d that gradually decreases in diameter upward is integrally provided at the opening end (upper end) of the main body portion 91c, and the upper end opening of the reduced diameter seal portion 91d is a ball. The diameter is smaller than 92.

  The bottom wall 91e of the main body portion 91c is connected to the cylindrical portion of the main body portion 91c via a hinge 91f so as to be freely opened and closed. By adopting such a configuration, the adapter body 91 using a synthetic resin material or the like is molded by injection molding, and a molded product having a shape in which the bottom wall 91e is opened with respect to the cylindrical portion of the main body portion 91c is formed. By rotating the bottom wall 91e about the hinge 91f and closing the cylindrical portion of the main body 91c with the bottom wall 91e, the adapter body 91 having the above-described configuration can be easily formed.

  The ball 92 has a slightly smaller diameter than the inner diameter of the main body portion 91c, and a closed position in which the ball 92 is in contact with the reduced diameter seal portion 91d over the entire circumference and closes the opening of the main body portion 91c. The main body 91c is movable in the vertical direction between an open position that contacts the bottom wall 91e of the main body 91c and opens the opening of the main body 91c.

  When the container main body 10 is in the upright posture, the switching valve 90 having such a configuration is held in an open position where the ball 92 is in contact with the bottom wall 91e by its own weight, and the air hole 13 (that is, the communication hole). 93 and the internal space of the main body portion 91c), while allowing the air flow to the air flow path P1, the ball 92 is reduced in diameter by its own weight when the container main body 10 is tilted 90 degrees or more from the upright posture. By moving to the closed position in contact with the part 91d and closing the opening of the main body part 91c, the air flow from the air chamber 14 to the air flow path P1 through the air hole 13 is actuated.

  That is, by providing the switching valve 90 in the air hole 13, the squeeze discharge container 1 discharges the content liquid L in a bubble shape when the container main body 10 is in the upright posture, and the container main body 10 is 90 degrees from the upright posture. When it is tilted as described above, the content liquid L is automatically switched to be discharged in a liquid state.

  That is, as shown in FIG. 3, when the trunk portion 10b is squeezed while the container body 10 is in an upright posture, the switching valve 90 is open at this time, so the air chamber pressurized by the squeeze 14 air is supplied to the air flow path P <b> 1 through the air holes 13. When air is supplied to the air flow path P1, the air pressure check valve 70 is closed by the increase in pressure, and the air opens the air flow path check valve 60 through the communication path 24, and foams. The member 80 is reached. When the body 10b is squeezed while the container body 10 is in an upright posture, the inner layer body 11 is pressurized via the air in the air chamber 14, and the ball 52 moves to the open position by the pressure of the content liquid L. Then, the check-out valve 50 for the dispensing hole is opened. Then, the content liquid L is poured out from the pouring hole 23 and reaches the foaming member 80. The content liquid L that has reached the foaming member 80 is mixed with the air supplied from the communication path 24 inside the foaming member 80 to foam, and flows in the form of bubbles toward the discharge flow path P2. The foamed liquid L is made finer by passing through the pair of foam regulating members 81 and then discharged from the nozzle 40 through the extended nozzle 41 to the outside in the form of foam.

  Even when the body portion 10b is squeezed while the container body 10 is tilted at an angle of less than 90 degrees with respect to the upright posture, the content liquid L can be similarly discharged from the nozzle 40 in the form of bubbles.

  On the other hand, as shown in FIG. 4, when the barrel 10b is squeezed while the container body 10 is tilted 90 degrees or more from the upright posture, the switching valve 90 causes the ball 92 to drop by its own weight. Thus, the air in the air chamber 14 pressurized by the squeeze passes through the air holes 13 and does not flow out to the air flow path P1 and enters the air chamber 14 because the air is closed. Fastened. Therefore, when the body portion 10b is squeezed with the container body 10 tilted 90 degrees or more from the upright posture, air is not supplied to the foam member 80. On the other hand, even when the body 10b is squeezed with the container body 10 tilted 90 degrees or more from the upright posture, the inner layer body 11 is pressurized via the air in the air chamber 14, The ball 52 moves to the open position due to the pressure of the content liquid L, the check valve 50 for the discharge hole is opened, and the content liquid L is supplied to the foaming member 80 through the discharge hole 23. However, as described above, since air is not supplied to the foaming member 80, the content liquid L that has reached the foaming member 80 is not mixed with air inside the foaming member 80, and remains in a liquid state without being discharged. The liquid is discharged outside through P2, the pair of foam regulating members 81, the nozzle 40 and the extension nozzle 41.

  As described above, the squeeze discharge container 1 can discharge the content liquid L from the nozzle 40 in the form of bubbles by squeezing the body portion 10b while keeping the container body 10 in an upright posture. By squeezing the body portion 10b while being tilted by 90 degrees or more from the upright posture, the content liquid L can be discharged from the nozzle 40 in a liquid state. Therefore, the content liquid L can be selectively discharged in either a foam or liquid state by a simple operation that only changes the posture of the container body 10 when the body 10b of the container body 10 is squeezed.

  It goes without saying that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.

  For example, the configuration of the inner plug member 20 and the cap 30 is such that the content liquid L poured out from the outlet hole 23 provided in the inner plug member 20 is transferred from the air chamber 14 to the air hole 13 and the air flow path in the foam member 80. If it is the structure which can be mixed and foamed with the air supplied through P1, the structure can be changed suitably.

  The switching valve 90 can also be configured to be detachably attached to the air hole 13. In this case, by removing the switching valve 90 from the air hole 13, the squeeze discharge container 1 can be easily switched to a configuration that allows the content liquid L to be discharged only in the form of foam.
