The mesh member 70 arranged so as to overlap the protection portion 80 covers the entire eight flow holes 81 of the protection portion 80. A slight gap is provided between the outer peripheral surface of the rear end side of the fitting cylinder portion 71a to which the mesh member 70 is fixed and the inner peripheral surface of the nozzle 62.

The mesh member 70 may be fixed to the rear end faces of the horizontal ribs 80a and the vertical ribs 80b in addition to the rear end faces of the fitting cylinder portion 71a by means such as adhesion.

In the foam discharge container 1 having the above configuration, when the push-down head 60 is pushed down, the pump 40 operates, and the content liquid sucked from the suction pipe 50 is pumped to the nozzle 62 while being mixed with air. To. The content liquid that has been pumped up to the nozzle 62 passes through the mesh member 70 arranged in the flow path 62a inside the nozzle 62, and becomes a fine foam. The content liquid that has passed through the mesh member 70 and has a fine texture in the form of bubbles passes through the eight flow holes 81 of the protective portion 80 and is discharged to the outside from the open end of the nozzle 62.

As described above, according to the foam discharge tool 20 or the foam discharge container 1 of the present embodiment, the mesh member 70 is arranged inside the nozzle 62, so that the mesh member 70 is pumped to the nozzle 62 while being mixed with air. The content liquid that has been collected can be discharged from the nozzle 62 to the outside as a foam having a finer texture inside the nozzle 62.

Further, according to the foam discharge tool 20 or the foam discharge container 1 of the present embodiment, when the elongated member unexpectedly invades the inside of the nozzle 62 by providing the protective portion 80 inside the nozzle 62, the said It is possible to prevent the member from coming into contact with the protective portion 80 and invading the position where the member comes into contact with the mesh member 70. As a result, the mesh member 70 can be arranged inside the nozzle 62 so that the content liquid can be discharged from the nozzle 62 to the outside in the form of finer foam, and the mesh member 70 can be suppressed from being damaged. ..

Further, in the foam discharge tool 20 or the foam discharge container 1 of the present embodiment, the nozzle 62 has a shape in which the cross-sectional area perpendicular to the axial direction gradually expands from the base end side to the tip end side thereof. Since the mesh member 70 is arranged in the enlarged portion of the mesh member 70, a larger mesh member 70 can be used. As a result, the resistance when the content liquid passes through the mesh member 70 can be reduced, so that the pressing force of the pressing head 60 required to discharge the content liquid can be reduced, and the operation is easier. The content liquid can be discharged from the nozzle 62 in the form of bubbles.

Further, according to the foam discharge tool 20 or the foam discharge container 1 of the present embodiment, the protective portion 80 is formed in a grid pattern having a plurality of flow holes 81, so that the content liquid can be distributed. While securing the area of the hole 81, it is possible to effectively prevent the member that has entered the inside of the nozzle 62 from entering the position where it comes into contact with the mesh member 70. Therefore, it is possible to suppress damage to the mesh member 70 while reducing the pressing force of the pressing head 60 required to discharge the content liquid.

Further, in the foam discharge tool 20 or the foam discharge container 1 of the present embodiment, the mesh member 70 is arranged so as to be overlapped with the protective portion 80 formed in a grid pattern, so that the flow of the nozzle 62 having a large cross-sectional area is formed. Even when a larger mesh member 70 is used corresponding to the path 62a, each part of the mesh member 70 is supported by the grid-shaped protective portion 80, and the mesh member 70 is supported by the resistance when the content liquid is discharged. It is possible to suppress the occurrence of bending. As a result, the content liquid can be more stably discharged in the form of high-quality foam.

In the foam discharge tool 20 or the foam discharge container 1 of the present embodiment, the nozzle 62 is formed in a shape through which the suction pipe 50 can be inserted. That is, as shown in FIG. 2, the horizontal dimension and the vertical dimension of the flow path 62a at the open end of the nozzle 62 are both larger than the outer diameter dimension of the suction pipe 50 (indicated by the alternate long and short dash line in FIG. 2). It's getting bigger. In the foam ejector 20 having such a configuration, when a large amount of foam ejector 20 is transported or the like before being mounted on the container body 10, another foam ejector 20 is inside the nozzle 62 of the foam ejector 20. There is a risk that the suction pipe 50 of the above will unexpectedly invade.

On the other hand, in the foam discharge tool 20 of the present embodiment, the protection portion 80 is formed so that the flow hole 81 cannot insert the suction pipe 50. More specifically, each flow hole 81 has a shape in which at least one of its vertical dimension and horizontal dimension is smaller than the outer diameter dimension of the suction pipe 50 (indicated by the alternate long and short dash line in FIG. 2). It is formed. Therefore, even if the suction pipe 50 of another foam discharge tool 20 suddenly enters the inside of the nozzle 62 of the foam discharge tool 20, the suction pipe 50 cannot pass through the flow hole 81, and the protection unit 80 That is, it is suppressed that the horizontal rib 80a or the vertical rib 80b is in contact with at least one of the horizontal ribs 80a and the vertical rib 80b is in contact with the mesh member 70. As a result, even when the nozzle 62 is formed in a shape through which the suction pipe 50 can be inserted, the mesh member 70 is formed by the suction pipe 50 of the other foam ejector 20 that has suddenly entered the inside of the nozzle 62. Can be prevented from being damaged.

(Not shown in FIG. 6) and a flange portion 71b connected to the fitting cylinder portion are provided, and a cylindrical projecting cylinder 71c is integrally provided on the lateral outer surface of the collar portion 71b facing the side opposite to the nozzle 62. It has a structure. The protruding cylinder 71c forms a part of the nozzle 62, and the inside thereof is a flow path 62a for the content liquid.

Six claws 71d are integrally provided on the outer surface of the projecting cylinder 71c in the axial direction facing the side opposite to the flange 71b. Each of the six claws 71d has a shape that extends parallel to the axis of the protruding cylinder 71c and gradually becomes thinner at the tip, and is arranged at equal intervals in the circumferential direction around the axis of the protruding cylinder 71c. Has been done.

In the foam discharge tool 20 of the modified example shown in FIGS. 4 to 6, the protective portion 80 is provided inside the fitting cylinder portion and the flange portion 71b. More specifically, as shown in FIG. 6, the protective portion 80 is arranged so as to project from the inner peripheral surfaces of the fitting cylinder portion and the flange portion 71b, which form a part of the nozzle 62, respectively, and have their end faces facing each other. It has a pair of partition walls 80c. Each partition wall 80c extends from the flange portion 71b to the rear end portion of the fitting cylinder portion (the end facing the opening end of the nozzle 62), and the flange portion 71b and the inside of the fitting cylinder portion are It is a horizontally long and substantially rectangular flow hole 81 partitioned by a pair of partition walls 80c. The flow hole 81 constitutes a part of the flow path 62a, and the content liquid pumped into the flow path 62a of the nozzle 62 is discharged to the outside through the flow hole 81.

The mesh member 70 is fixed to the rear end surface of the fitting cylinder portion (the end surface facing the side opposite to the opening end of the nozzle 62) by means such as adhesion or welding, and is protected in a posture perpendicular to the axial direction of the nozzle 62. It is arranged so as to overlap the protection portion 80 on the upstream side of the portion 80. In addition to the rear end surface of the fitting cylinder portion, the mesh member 70 may be fixed to the rear end surface of the pair of partition walls 80c (the surface facing the upstream side of the flow path 62a) by means such as adhesion or welding. Good.

Further, the protective portion 80 is integrally provided at the rear end portion of each partition wall 80c, and has a pair of protrusions 80d protruding from the inner surface of the partition wall 80c toward the axis of the nozzle 62 or the protruding cylinder 71c. There is. The pair of protrusions 80d are each provided at the center position in the width direction of the rear end portion of the partition wall 80c.

Reference numeral 90 is a stopper member that is attached to the support cylinder 33 during distribution or when not in use to regulate the pressing operation of the pressing head 60.

Even in the foam discharge container 1 using the foam discharge tool 20 of the modified example having the above configuration, the content liquid that has been pressure-fed to the nozzle 62 is arranged in the flow path 62a at the rear end surface of the fitting cylinder portion or the protection portion 80. By passing through the mesh member 70, it becomes a fine foam. Further, the content liquid that has passed through the mesh member 70 and has a fine texture in the form of bubbles enters between the adjacent claws 71d of the six claws 71d, and the tip side of these claws 71d. By being discharged from, the outer peripheral surface is discharged to the outside in a shape having a streak-like unevenness corresponding to the space between the claw portions 71d. When the foam-like content liquid is discharged with the tips of the six claw portions 71d pressed against the object to be discharged such as the palm, the foam-like content liquid is discharged from between the adjacent claw portions 71d. It can be discharged radially.

Further, also in the foam discharge container 1 using the foam discharge tool 20 of the modified example, by providing the protective portion 80 inside the fitting cylinder portion and the flange portion 71b, the nozzle 62 passes through the inside of the six claw portions 71d. A position where the member abuts on one or both of the pair of partition walls 80c constituting the protective portion 80 and the member abuts on the mesh member 70 when an elongated member unexpectedly invades the inside of the. It is possible to suppress the invasion to. As a result, the mesh member 70 is arranged inside the nozzle 62, so that the content liquid can be discharged from the nozzle 62 to the outside in the form of a finer foam, and damage to the mesh member 70 can be suppressed. .. Further, by providing the pair of protrusions 80d at the rear end of each partition wall 80c, even if an elongated member invades the flow hole 81 between the pair of partition walls 80c, the member hits the protrusion 80d. It is possible to prevent the elongated member from invading to the position where it comes into contact with the mesh member 70. Therefore, while ensuring the cross-sectional area of the flow hole 81, it is possible to more effectively prevent the elongated member that has entered the inside of the projecting cylinder 71c from entering the position where it comes into contact with the mesh member 70.

Even in the foam discharge container 1 using the foam discharge tool 20 of the modified example, the protection portion 80 is formed in a shape in which the flow hole 81 cannot insert the suction pipe 50. More specifically, the flow hole 81 is formed in a shape whose vertical dimension is smaller than the outer diameter dimension of the suction pipe 50 (indicated by the alternate long and short dash line in FIG. 6). Further, the distance between the pair of protrusions 80d is also smaller than the outer diameter of the suction pipe 50. Therefore, even if the suction pipe 50 of the other foam discharge tool 20 suddenly enters the inside of the nozzle 62, the suction pipe 50 abuts on any of the pair of partition walls 80c and passes through the flow hole 81. It is not possible to prevent the mesh member 70 from entering the position where it comes into contact with the mesh member 70. Further, even when the suction pipe 50 is deformed so as to have an elliptical cross section and enters the flow hole 81 of the pair of partition walls 80c, it is provided at the rear end portion of the pair of partition walls 80c. When the suction pipe 50 comes into contact with the protrusion 80d, it is possible to prevent the suction pipe 50 from invading to a position where it comes into contact with the mesh member 70. As a result, even when the nozzle 62 is formed in a shape that allows the suction pipe 50 to be inserted, the mesh member is formed by the suction pipe 50 of the other foam discharge tool 20 that has suddenly entered the inside of the protruding cylinder 71c. It is possible to prevent the 70 from being damaged.

Further, in the foam discharge container 1 using the foam discharge tool 20 of the modified example, the foam discharge container 1 is connected to the rear end surface of the fitting cylinder portion at the center position in the width direction of the rear end portion of the pair of partition walls 80c, and is connected to the nozzle 62 or the flow hole. Since a pair of protrusions 80d protruding toward the axial center of 81 are provided, the upper and lower portions of the mesh member 70 fixed to the rear end surface of the fitting cylinder portion at the center position in the width direction are supported by the protrusions 80d, respectively. It is possible to prevent the mesh member 70 from bending due to the resistance when the content liquid is discharged. As a result, the content liquid can be more stably discharged in the form of high-quality foam.

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 gist thereof.

For example, in the above-described embodiment, the protective portion 80 has a structure formed in a grid pattern or a structure having a pair of partition walls 80c and a pair of protrusions 80d, but the present invention is not limited to this, and the content liquid flows through the distribution. If the nozzle 62 is provided with a hole 81, the shape of the protective portion 80 can be changed in various ways, for example, the protective portion 80 is formed in a rib shape.

Further, the positions of the mesh member 70 and the protective portion 80 can be arbitrarily changed as long as they are provided inside the nozzle 62.

Further, in the above-described embodiment, the nozzle 62 is formed in a shape through which the suction pipe 50 can be inserted, but is not limited to this, and the suction pipe 50 is formed in a shape in which the suction pipe 50 cannot be inserted. It can also be a pipe.
