The discharge cylinder 51 has a discharge flow path P2 communicating with the extraction hole 20c and the air flow path P1 inside thereof. The communication structure between the air flow path P1 and the discharge flow path P2 will be described later.

  A pouring hole check valve 60 is disposed in the pouring hole 20 c of the inner plug member 20. The check-out valve 60 for the pouring hole is arranged on the upper surface of the inner plug main body 20b so as to close the pouring hole 20c, and the valve body 60a is connected to the inner peripheral surface of the connecting cylinder portion 50. And three (only two are shown in FIG. 1) crank-shaped connecting arm portions 60b to be supported. That is, the check-out valve 60 for the dispensing hole is formed as a three-point valve having a valve body 60a that is integrally provided on the inner peripheral surface of the connecting cylinder part 50 via the connecting arm part 60b. In addition, the check valve 60 for pouring holes is not limited to a three-point valve, and may be a one-point valve, or a valve body having another configuration may be used.

  The check-out valve 60 for the pouring hole is poured out from the inside of the inner layer body 11, that is, from the filling space M by opening the pouring hole 20 b by moving the valve body 60 a away from the pouring hole 20 c by the pressure of the content liquid. While allowing the flow of fluid (content liquid and air) to the discharge flow path P2 through the hole 20c, the valve body 60a elastically abuts against the upper surface of the inner plug body 20b so as to close the discharge hole 20c. By this, it operates so that the flow of the fluid from the discharge flow path P2 to the inside of the inner layer body 11 through the extraction hole 20c may be prevented. Therefore, by squeezing the barrel portion 10b of the container body 10, the content liquid accommodated in the filling space M can be poured out toward the discharge flow path P2 through the extraction hole 20c, while the squeeze portion of the barrel portion 10b. When the is released, the content liquid and air remaining in the discharge flow path P2 are prevented from being introduced into the inner layer body 11 through the extraction hole 20c.

  An air hole check valve 70 is provided in the air flow path P1. The air hole check valve 70 is provided integrally with the outer peripheral surface of the connecting tube portion 50, and includes an annular and membrane-like valve body 70a extending from the outer peripheral surface toward the radially outer side. The valve body 70a is elastically brought into contact with the upper surface of the step portion 24 provided on the inner peripheral portion of the fitting portion 22 of the inner plug member 20 at the outer peripheral edge thereof to block or block the air flow path P1 in the middle thereof. doing.

  The air hole check valve 70 moves in a direction in which the valve body 70a moves away from the step portion 24 by the pressure of the air supplied from the air hole 13 to the air flow path P1 by the squeeze of the body portion 10b. Opening allows the flow of fluid (air) from the air hole 13 to the discharge flow path P2 through the air flow path P1, and allows the valve body 70a to contact the step portion 24 so that the air flow from the discharge flow path P2 It operates so as to block the flow of fluid to the air hole 13 through the path P1. Therefore, by squeezing the trunk portion 10b of the container body 10, the air accommodated in the air chamber 14 can be supplied toward the discharge passage P2 through the air holes 13 and the air passage P1, while the trunk portion. When the squeeze of 10b is released, the content liquid and air remaining in the discharge flow path P2 are prevented from being introduced into the air chamber 14 through the air flow path P1 and the air holes 13.

  The squeeze discharge container 1 may be configured such that the air hole check valve 70 is not provided, for example, by providing a throttle portion in the air flow path P1, but the air hole check valve 70 is provided. As a result, it is possible to reliably prevent the content liquid 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.

  In order to take outside air into the air chamber 14 due to the negative pressure accompanying the restoration of the body portion 10b when the squeeze of the body portion 10b is released after the liquid and air are discharged by the squeeze of the body portion 10b, the cap 30 Is provided with an open hole 36 and a ball valve 37.

  The open hole 36 is connected to the air flow path P1 through the open passage 25 provided in the fitting portion 22 of the inner plug member 20, and can open the air flow path P1 to the outside. The ball valve 37 is disposed inside a cylindrical body 38 having a narrowed upper end, and the container body 10 is in an upright position so that the discharge port 42 faces downward from an upright position with the cap 30 on the upper side. When it is tilted 90 degrees or more, the opening of the cylinder 38 is closed and the opening 36 is closed. Thus, when the content liquid is discharged by squeezing the body portion 10b with the discharge port 42 facing downward, the open hole 36 is closed, and the air supplied from the air chamber 14 to the air flow path P1 is discharged. It can supply to the discharge flow path P2 without opening outside.

  In place of the opening hole 36 and the ball valve 37, for example, an opening hole and a valve body having the same function are provided in other parts such as the body portion 10b of the outer layer body to introduce outside air into the air chamber 14. You can also

  A foam member F is provided in the discharge flow path P2. As the foam member F, for example, a porous body or a mesh member formed of a sintered body, a foam (such as a sponge), or the like can be used. The liquid content poured out from the filling space M into the discharge flow path P2 through the discharge hole 20c and the air supplied from the air chamber 14 through the air flow path P1 to the discharge flow path P2 are respectively passed through the foaming member F and foamed. The members F are mixed with each other. As a result, the content liquid is mixed with air in the foaming member F, foamed, and discharged from the discharge port 42.

  The foam member F is formed in an annular shape, and a rod-like body 61 provided integrally with the valve body 60a of the check-out valve 60 for the extraction hole passes through the axial center thereof. On the other hand, a lid 62 that closes the discharge port 42 is detachably attached to the tip of the nozzle portion 41. A columnar pressing portion 62a protrudes from the inner surface of the lid 62, and when the lid 62 is attached to the tip of the nozzle portion 41, the pressing portion 62a abuts on the tip of the rod-shaped body 61 so that the valve body 60a is inside. The pouring hole 20c is maintained in a closed state in contact with the upper surface of the stopper body 20b. Thereby, the leakage of the content liquid when not in use can be effectively prevented.

  An opening / closing mechanism 80 is provided between the air flow path P1 and the discharge flow path P2. The opening / closing mechanism 80 can be switched between an open state in which the air flow path P1 communicates with the discharge flow path P2 and a closed state in which the air flow path P1 is blocked from the discharge flow path P2. That is, the opening / closing mechanism 80 causes the squeeze discharge container 1 to discharge the content liquid in a liquid state by blocking the mixing of air into the content liquid and the foam discharge mode in which the content liquid is mixed with air and discharged in the form of bubbles. The liquid discharge mode can be switched to.

  A communication passage 81 is defined between the top wall portion 30 b of the cap 30 and the tip of the connecting tube portion 50. In the case shown in the figure, a pair of communication passages 81 is provided in an opposing arrangement with the axial center of the connecting tube portion 50 as the center. As shown in FIG. 2, these communication passages 81 are each formed in a groove shape having a sufficiently narrow width with respect to the entire circumference of the connecting cylinder portion 50, and as shown in FIG. It communicates with P1.

  On the other hand, a pair of communication grooves 82 corresponding to the pair of communication passages 81 are provided on the outer peripheral surface of the nozzle portion 41. Each of the communication grooves 82 extends along the axial direction from the base end of the nozzle portion 41, and communicates with the discharge flow path P2 on the base end side. Further, the base end of the communication groove 82 extends along the radial direction of the nozzle portion 41 at the end portion of the nozzle portion 41 and penetrates the inner peripheral surface side of the nozzle portion 41.

  An annular groove 83 is provided on the side surface of the foam member F, and a base end extending along the radial direction of the nozzle portion 41 of the communication groove 82 is opened at a position facing the annular groove 83. Thereby, the air blown out toward the discharge flow path P <b> 2 through the communication groove 82 can be effectively supplied to the foaming member F through the annular groove 83.

  In addition, the annular groove 83 is not provided on the side surface of the foam member F, and a stepped and annular notch portion that faces the inner peripheral surface of the nozzle portion 41 and communicates with the communication groove 82 is provided at the base end of the nozzle portion 41. The air blown out toward the discharge flow path P2 through the communication groove 82 may be supplied to the foaming member F from the entire periphery through the notch.

  By rotating the nozzle head 40 with respect to the cap 30, the opening / closing mechanism 80 can be switched between the open state and the closed state, that is, the squeeze discharge container 1 between the bubble discharge mode and the liquid discharge mode.

  When the nozzle head 40 is in the open position shown in FIG. 2 with respect to the cap 30, the communication groove 82 overlaps the corresponding communication path 81, and the opening / closing mechanism 80 is in an open state in which the air flow path P1 communicates with the discharge flow path P2. Become. Thus, when the nozzle head 40 is in the open position, the opening / closing mechanism 80 is in the open state, and the squeeze discharge container 1 is set in the foam discharge mode.

  As shown in FIG. 3, in the foam discharge mode, the container body 10 is tilted 90 degrees or more from the upright posture so that the discharge port 42 of the nozzle portion 41 faces downward, and in this state, the body portion 10b is squeezed. The liquid in the filling space M is poured from the spout 20c toward the discharge flow path P2, and the air in the air chamber 14 is supplied from the air flow path P1 to the discharge flow path P2, and these are mixed in the foam member F. Thus, the content liquid can be discharged from the discharge port 42 in the form of foam. At this time, since the ball valve 37 is in contact with the inner surface of the reduced diameter portion 38a provided at the upper end of the cylindrical body 38 over the entire circumference, the open hole 36 is closed to the outside. Air is supplied to the discharge passage P2 from the open hole 36 without leaking outside.

  When the container main body 10 is returned to the upright posture and the squeeze of the body portion 10b is released, the pouring hole 20c is closed by the pouring hole check valve 60, and the air flow path by the air hole check valve 70. When P1 is shut off and the ball valve 37 is opened and outside air is introduced into the air chamber 14 from the opening hole 36, the body 10b can be restored to its original shape while the inner layer body 11 is deformed and reduced. it can. Thereby, intrusion of air into the inner layer body 11 can be prevented, deterioration of the content liquid can be suppressed, and inflow of the content liquid into the air chamber 14 through the air flow path P1 is prevented. .

  On the other hand, when the nozzle head 40 is rotated clockwise in FIG. 2 with respect to the cap 30 to the closed position shown in FIG. 4 and FIG. As shown in FIG. 4, the air flow path P1 is blocked from the discharge flow path P2. Thus, when the nozzle head 40 is in the closed position, the opening / closing mechanism 80 is closed. The squeeze discharge container 1 is set to the liquid discharge mode.

  In the liquid discharge mode, even if the container body 10 is tilted 90 degrees or more from the upright posture so that the discharge port 42 of the nozzle portion 41 faces downward, and the body portion 10b is squeezed in this state, the content liquid in the filling space M Is discharged from the spout 20c toward the discharge flow path P2, but the air in the air chamber 14 is not supplied to the discharge flow path P2, and the content liquid is discharged in liquid form from the discharge port 42.

  As shown in FIGS. 2 and 5, a pair of moving pieces 43 are integrally provided on the inner peripheral surface of the nozzle head 40 so as to be opposed to each other centering on the axial center. 43 is arrange | positioned between a pair of stopper pieces 26 integrally provided in the upper surface of the inside plug main body 20b. Then, the movement of the moving piece 43 is restricted by the stopper piece 26, whereby the rotation range of the nozzle head 40 relative to the cap 30 is restricted. As shown in FIG. 2, the nozzle head 40 is in the open position when the pair of moving pieces 43 come into contact with one of the corresponding stopper pieces 26, as shown in FIG. The nozzle head 40 is in the closed position when the pair of moving pieces 43 come into contact with the other stopper piece 26 of the corresponding pair of stopper pieces 26.

  As described above, in the squeeze discharge container 1 of the present invention, the air flow path P1 is opened and closed with respect to the discharge flow path P2 by the opening / closing mechanism 80 by a simple operation of simply rotating the nozzle head 40. By switching, the content liquid discharged from the squeeze discharge container 1 can be switched between foam and liquid.

  As shown in FIG. 6 as a modified example, in the squeeze discharge container 1, the cap 30 is separated from the mounting cylinder 30a and the ceiling wall 30b, and the ceiling wall 30b is connected to the mounting cylinder 30a via a hinge 90.
