Can be stopped with. The position where the engaging protrusion 3j engages with the lowering position stopper 2m is referred to as a lowering position, the position where the engaging protrusion 3j engages with the intermediate position stopper 2n is referred to as an intermediate position, and the engaging protrusion 3j rises. The position where the position stopper portion 2p is engaged is referred to as an ascending position.

Further, the partition wall 3d is provided with a holding portion 3k for holding the connecting member 10. In the present embodiment, as shown in the drawing, a hole penetrating the partition wall 3d is provided and an annular wall surrounding the hole is provided to hold the holding portion 3k.

As shown in FIG. 1, the pipe 5 extends toward the bottom portion 1a and bends toward the direction side of the nozzle 3c. Here, the opening at the lower end of the pipe 5 introduces the content liquid of the accommodating space S into the inside of the foam forming member 4, and hereinafter, this opening is referred to as a liquid introduction port 5a.

As shown in FIG. 2, the connecting member 6 is provided at a connecting member main body 6a having a bottomed tubular shape and having a portion inclined downward from the upper end thereof, and a central portion of the connecting member main body 6a. The fitting cylinder 6b that surrounds the hole and fits and holds the upper end of the pipe 5 and the outer edge of the bottomed tubular portion of the connecting member main body 6a are penetrated to allow air in the accommodation space S to flow inside the foam forming member 4. It is equipped with an air inlet 6c that functions to be introduced into the air. Further, a plurality of ribs 6d are provided inside the connecting member main body 6a.

The cylinder 7 is formed so as to form a substantially cylindrical shape, and the connecting member main body portion 6a is inserted into the lower end portion thereof to fit and hold the connecting member 6. Here, the internal space of the cylinder 7 is referred to as a mixing chamber 7a. A shaft portion 7b is provided inside the cylinder 7. The upper end of the shaft portion 7b is connected to the inner peripheral surface of the cylinder 7 by connecting portions spaced in the circumferential direction. Here, when the connecting member 6 is combined with the cylinder 7, the shaft portion 7b is surrounded by a plurality of ribs 6d, but since a gap is provided between them, the cylinder is passed through the liquid introduction port 5a. The content liquid introduced into 7 and the air introduced into the cylinder 7 through the air introduction port 6c can pass through the gap between the rib 6d and the shaft portion 7b, and further pass through the gap between the connecting portions described above. ..

The foaming member 8 foams the content liquid and air that pass through the foaming member 8. In the present embodiment, a mesh-like mesh is provided on one side of a cylindrical base, and two of them are arranged in series and held inside the cylinder 7. .. The number and arrangement of the foaming members 8, the size of the mesh, and the like are appropriately selected so that the content liquid to be applied has the optimum foam quality.

The check valve 9 is composed of a base portion 9a which is annular and is fitted and held in the cylinder 7, and a thin valve plate portion 9b which extends radially outward from the outer peripheral surface of the base portion 9a to form a donut plate shape. It is configured.

The connecting member 10 is formed in the shape of a covered cylinder as a whole, and a connecting passage 10a leading to the mixing chamber 7a via the foaming member 8 is formed inside the connecting member 10. The upper end of the connecting member 10 is inserted into the holding portion 3k of the nozzle head 3 to be fitted and held, and the lower end thereof is inserted into the upper opening of the cylinder 7 to fit and hold the cylinder 7. As a result, the foam forming member 4 composed of the cylinder 7, the connecting member 10, and the like can be moved up and down according to the up and down movement of the nozzle head 3. Further, the side wall of the connecting member 10 is provided with a communication hole 10b for passing the above-mentioned distribution port 2k and the connecting passage 10a.

Then, an annular passage is formed between the outer surface of the foam forming member 4 and the inner surface of the mounting cap 2 through which the accommodating space S and the distribution port 2k pass. Here, this passage will be referred to as an introduction passage T. The foam forming member 4 moves up and down in response to the up and down movement of the nozzle head 3, so that the valve plate portion 9b of the check valve 9 separates or comes into contact with the valve seat 2g. Specifically, in the state shown in FIG. 2 (lowering position) and the state shown in FIG. 3 (intermediate position), the valve plate portion 9b is separated from the valve seat 2g, and the introduction passage T is in an open state. On the other hand, in the state shown in FIG. 4 (rising position), the valve plate portion 9b is in contact with the valve seat 2g, and the introduction passage T is in a closed state.

In the discharge container having such a configuration, when the nozzle head 3 is rotated clockwise with respect to the mounting cap 2, the second female screw portion 3b is tightened with respect to the second male screw portion 2r, and accordingly. The nozzle head 3 and the foam forming member 4 descend. As the nozzle head 3 is rotated, as shown in the cross-sectional view of B1-B1 in FIG. 2, the engaging protrusion 3j comes into contact with the large protrusion at the lowering position stopper portion 2m to stop the rotation. The nozzle head 3 does not rotate excessively.

As shown in FIG. 2, at the lowering position where the engaging protrusion 3j engages with the lowering position stopper portion 2m, the opening / closing lid portion 3f abuts on the distribution cylinder 2j and the distribution port 2k and the communication port 3e are not communicated with each other. That is, since it is difficult for the outside air to enter the accommodation space S through the nozzle 3c, the contact between the content liquid and the outside air is suppressed, and the quality of the content liquid can be maintained. Further, even if the container body 1 is tilted in this state, the content liquid does not overflow.

Then, when it is desired to discharge the content liquid in a liquid state, the nozzle head 3 is rotated counterclockwise from the state of FIG. 2 to the intermediate position shown in FIG. 3, and bubbles are formed with the nozzle head 3 with respect to the mounting cap 2. The member 4 is raised. At the intermediate position, when the engaging protrusion 3j gets over one small protrusion at the intermediate position stopper portion 2n, the feeling is transmitted to the hand holding the nozzle head 3, so that it is possible to know that the position has been reached.

At the intermediate position shown in FIG. 3, the valve plate portion 9b is separated from the valve seat 2g, and the introduction passage T is in an open state. Further, the opening / closing lid portion 3f is separated from the distribution cylinder 2j, and the distribution port 2k and the communication port 3e communicate with each other. Therefore, as shown in FIG. 5A, the container body 1 is tilted (the body portion 1b is squeezed as necessary), and the content liquid of the storage space S is communicated with the introduction passage T, the distribution port 2k, and the communication port. It can be discharged to the outside world through the mouth 3e and the nozzle 3c.

If it is desired to discharge the content liquid in the form of bubbles, rotate the nozzle head 3 counterclockwise from the state of FIG. 3 to the ascending position shown in FIG. 4, and foam the nozzle head 3 with respect to the mounting cap 2. The forming member 4 is raised. At the ascending position, as shown in the cross-sectional view of B3-B3 in FIG. 4, the engaging projection 3j abuts on the large projection of the ascending position stopper portion 2p to stop its rotation, so that the nozzle head 3 rotates excessively. It's never too much.

At the ascending position shown in FIG. 4, since the valve plate portion 9b is in contact with the valve seat 2g, the flow of air and / or the content liquid toward the accommodation space S through the introduction passage T is allowed, while the introduction passage. The flow of air and / or content liquid through T toward the distribution port 2k will be regulated. Further, the opening / closing lid portion 3f is separated from the distribution cylinder 2j, and the distribution port 2k and the communication port 3e communicate with each other. Therefore, when the body portion 1b is squeezed with the container body 1 upright as shown in FIG. 5B, the internal pressure of the accommodation space S increases, and as a result, the content liquid becomes the liquid introduction port 5a (see FIG. 1). ) Passes through the inside of the pipe 5 and is introduced into the mixing chamber 7a, and the air in the accommodation space S is introduced into the mixing chamber 7a through the air introduction port 6c. Then, the content liquid and air mixed in the mixing chamber 7a are foamed by passing through the foaming member 8, and further pass through the connection passage 10a, the communication hole 10b, the distribution port 2k, the communication port 3e, and the nozzle 3c. It is discharged to the outside in the form of bubbles.

After the content liquid is discharged in the form of bubbles, the pressing on the body portion 1b is released. As a result, when the restoration of the body portion 1b begins, the volume of the accommodation space S increases and the accommodation space S becomes a negative pressure. Here, since the valve plate portion 9b can be separated from the valve seat 2g, the outside air is introduced into the accommodation space S via the nozzle 3c, the communication port 3e, and the introduction passage T, so that the body portion 1b is the original. Restore to state. When the outside air is introduced into the accommodation space S, the content liquid remaining in the nozzle 3c is also pulled back to the accommodation space S (suckback function). Therefore, it is possible to prevent the residual content liquid from dripping from the nozzle 3c.

As shown in the front views of FIGS. 2, 3 and 4, the mounting cap 2 and the nozzle head 3 have indexes (or the above-mentioned descending position, intermediate position, and ascending position) indicating the properties of the discharged content liquid. It is preferable to provide an index) so that the indicator can be visually recognized.

Next, a second embodiment of the discharge container according to the present invention will be described with reference to FIGS. 6 to 8. It should be noted that the description of the present embodiment will mainly focus on the points where the functions are different from those of the first embodiment, and basically, the parts having the same functions as the first embodiment are designated by common reference numerals in the drawings. The explanation will be omitted.

The discharge container of the present embodiment basically includes a mounting cap 2A and a nozzle head 3A in place of the mounting cap 2 and the nozzle head 3 provided in the discharge container of the first embodiment.

As shown in FIG. 6, the mounting cap 2A is provided with a stopper 2s at the lower end of the distribution cylinder 2j. Further, on the outer peripheral surface of the outer annular wall 2q, a plurality of outward protrusions 2t arranged at intervals in the vertical direction are provided. The lowering position stopper portion 2m, the intermediate position stopper portion 2n, and the ascending position stopper portion 2p of the first embodiment are abolished.

Further, the nozzle head 3A is provided with an inward projection 3m that engages with the outward projection 2t on the inner peripheral surface of the outer peripheral wall 3a. The engaging projection 3j of the first embodiment has been abolished.

In the discharge container of the present embodiment, the nozzle head 3A and the foam forming member 4 can be moved up and down by pulling up or pushing down the nozzle head 3A with respect to the mounting cap 2A.

FIG. 6 shows a state (lowering position) in which the nozzle head 3A is pushed down to the bottom with respect to the mounting cap 2A. At this position, since the inward protrusion 3m is engaged with the outward protrusion 2t, the nozzle head 3A will not be lifted carelessly. Further, at this position, since the opening / closing lid 3f abuts on the distribution cylinder 2j and the distribution port 2k and the communication port 3e are not communicated with each other, the invasion into the accommodation space S is prevented and the container body 1 is tilted down. It is possible to prevent the content liquid from overflowing.

If the liquid content is to be discharged in a liquid state, the nozzle head 3A is pulled up from the state shown in FIG. 6 to the state shown in FIG. 7 (the state in which the outward protrusion 2t engages with the upward protrusion 3m) ( Intermediate position). At this position, the valve plate portion 9b is separated from the valve seat 2g, and the introduction passage T is in an open state. Further, the opening / closing lid portion 3f is separated from the distribution cylinder 2j, and the distribution port 2k and the communication port 3e communicate with each other. Therefore, by tilting the container body 1 (by squeezing the body portion 1b if necessary), the content liquid of the accommodation space S is liquid through the introduction passage T, the distribution port 2k, the communication port 3e, and the nozzle 3c. It can be discharged as it is.

Then, when it is desired to discharge the content liquid in the form of bubbles, the nozzle head 3A is pulled up from the state shown in FIG. 7 to the state shown in FIG. 8 (the state in which the outward protrusion 2t engages with the upward protrusion 3m). (Ascending position). When the nozzle head 3A is pulled up to the raised position, as shown in FIG. 8, the upper end portion of the cylinder 7 comes into contact with the stopper 2s of the mounting cap 2A, so that the nozzle head 3A does not come off from the mounting cap 2A. At the ascending position, since the valve plate portion 9b is in contact with the valve seat 2g, the flow of air and / or the content liquid toward the accommodation space S through the introduction passage T is allowed, while the flow port is allowed through the introduction passage T. The flow of air and / or content liquid towards 2k is regulated. Further, the opening / closing lid portion 3f is separated from the distribution cylinder 2j, and the distribution port 2k and the communication port 3e communicate with each other. Therefore, when the body portion 1b is squeezed with the container body 1 upright, the contents liquid and air in the accommodation space S are introduced into the mixing chamber 7a, and the foaming member 8 is further formed, as in the above-described embodiment. It foams when it passes through it, and further passes through the connection passage 10a, the communication hole 10b, the flow port 2k, the communication port 3e, and the nozzle 3c, and can be discharged in the form of bubbles.

Next, a third embodiment of the discharge container according to the present invention will be described with reference to FIGS. 9 to 10. It should be noted that the description of the present embodiment also focuses mainly on the points where the functions are different from those of the first embodiment, and basically, the parts having the same functions as the first embodiment are designated by the common reference numerals in the drawings. The description will be omitted.

The discharge container of the present embodiment basically includes a mounting cap 2B and a nozzle head 3B in place of the mounting cap 2 and the nozzle head 3 provided in the discharge container of the first embodiment.

As shown in FIG. 9, the mounting cap 2B is provided with a stopper 2s at the lower end of the distribution cylinder 2j. Further, a male screw portion (third male screw portion) 2u is provided on the outer peripheral surface of the outer annular wall 2q. Then, as shown in the cross-sectional view taken along the line B4-B4 of FIG. 9, a descending position stopper portion 2m and an intermediate position stopper portion 2v are provided on the outer peripheral surface of the inner annular wall 2h. As shown in the figure, the intermediate position stopper portion 2v has a small protrusion similar to the small protrusion constituting the descending position stopper portion 2m, while the direction is opposite to that of the large protrusion constituting the descending position stopper portion 2m. It has a large protrusion.

The nozzle head 3B is provided with a third female threaded portion 3n that matches the third male threaded portion 2u on the inner peripheral surface of the outer peripheral wall 3a.

In the discharge container of the third embodiment, the nozzle head 3B is rotated with respect to the mounting cap 2B between the lowering position and the intermediate position, and the nozzle is rotated with respect to the mounting cap 2B between the intermediate position and the ascending position. By pulling up or pushing down the head 3B, the nozzle head 3B and the foam forming member 4 are moved up and down. As such a mechanism, in the present embodiment, the third male threaded portion 2u is divided in the middle of the circumferential direction and the third female threaded portion 3n is formed so as to be narrow, and in the section on the way from the descending position to the intermediate position. While the third male threaded portion 2u and the third female threaded portion 3n are screwed together, the narrow third female threaded portion 3n reaches the divided portion in the third female threaded portion 3n at the intermediate position, and both of them I am trying to unscrew. Further, at the position where the third male threaded portion 2u is divided, a protrusion protruding from the outer peripheral surface of the outer annular wall 2q is provided so as to engage the third female threaded portion 3n at the intermediate position and the rising position.

FIG. 9 shows a state (lowering position) in which the nozzle head 3B is rotated clockwise with respect to the mounting cap 2B and the nozzle head 3B is moved to the bottom. At this position, the opening / closing lid 3f abuts on the distribution cylinder 2j and the distribution port 2k and the communication port 3e are not communicated with each other, so that the intrusion into the storage space S is prevented and the container body 1 is tilted down. It is possible to prevent the content liquid from overflowing.

Then, when it is desired to discharge the content liquid in a liquid state, the nozzle head 3 is rotated counterclockwise from the state of FIG. 9 to the intermediate position shown in FIG. 10, and bubbles are formed with the nozzle head 3 with respect to the mounting cap 2. The member 4 is raised. At this position, as shown in the cross-sectional view taken along the line B5-B5 in FIG. 10, the engagement protrusion 3j abuts on the large protrusion in the intermediate position stopper portion 2v to stop its rotation, so that the nozzle head 3 is excessive. Don't turn too much. Further, at this position, the valve plate portion 9b is separated from the valve seat 2g, the introduction passage T is in an open state, and the opening / closing lid portion 3f is separated from the distribution cylinder 2j and communicates with the distribution port 2k. The mouth 3e communicates. Therefore, by tilting the container body 1 (by squeezing the body portion 1b as necessary), the content liquid of the accommodation space S is sent to the outside world through the introduction passage T, the distribution port 2k, the communication port 3e, and the nozzle 3c. It can be discharged.

When it is desired to discharge the content liquid in the form of bubbles, the nozzle head 3B is pulled up from the state shown in FIG. 10 to the state shown in FIG. 11 (raised position). As shown in FIG. 11, in the raised position, the upper end portion of the cylinder 7 comes into contact with the stopper 2s of the mounting cap 2B, so that the nozzle head 3B does not come off from the mounting cap 2B.

At the ascending position, since the valve plate portion 9b is in contact with the valve seat 2g, the flow of air and / or the content liquid toward the accommodation space S through the introduction passage T is allowed, while the flow port is allowed through the introduction passage T. The flow of air and / or content liquid towards 2k is regulated. Further, the opening / closing lid portion 3f is separated from the distribution cylinder 2j, and the distribution port 2k and the communication port 3e communicate with each other. Therefore, when the body portion 1b is squeezed with the container body 1 upright, the contents liquid and air in the accommodation space S are introduced into the mixing chamber 7a as in the first embodiment and the second embodiment, and further. It foams by passing through the foam member 8, and further passes through the connection passage 10a, the communication hole 10b, the distribution port 2k, the communication port 3e, and the nozzle 3c, and can be discharged to the outside in the form of bubbles.

The discharge container according to the present invention has been described above while showing specific embodiments, but the discharge container according to the present invention is not limited to the above-described embodiment, and various modifications are made within the scope of the claims. Also included. For example, the foam forming member 4 may have a function corresponding to the valve seat 2g of the mounting cap 2, and the mounting cap 2 may have a function corresponding to the check valve 9. Further, the configuration of the foam forming member 4 can be variously changed, and for example, the number of members constituting the foam forming member 4 can be arbitrarily changed.
