In recent years, in order to differentiate bubble ejectors, bubbles are ejected in a specific pattern from the nozzle outlet, and bubbles adhering to the object to be ejected (for example, a user's palm) become the specific pattern. There is a need in the market for shaping into a corresponding shape. In this case, for example, when ejected from the nozzle in the horizontal direction, the locus of the bubbles is bent due to gravity, so it is necessary to discharge downward from the nozzle. However, even if the bubbles are discharged downward from the nozzle, for example, if the user brings the palm too close to the discharge port, the force of the bubbles is so strong that the pattern of the specific shape collapses when the flow of bubbles collides with the palm. End up.
Therefore, it is desirable to prepare a table for mounting the object to be discharged at an appropriate distance from the discharge port, but when a dedicated mounting table for this application is incorporated into the foam discharger, the number of parts increases, It is not preferable because of high cost.

  An object of the present invention is to provide a foam discharger capable of combining a stopper for restricting the depression of a nozzle head and a mounting table for an object to be discharged with one part.

The first means comprises a mounting member 2 formed by erecting a guide tube portion 9 from an upper portion of the mounting tube portion 4 that can be mounted on the mouth and neck portion of the container body via an inward flange 8;
A cylinder member 14 suspended from the mounting member 2 into the container body 100;
The lower member 20a of the actuating member 20 is inserted into the cylinder member 14 in an upwardly biased state and can be moved up and down, and an intermediate tube portion 20b that passes through the inside of the guide tube portion 9 is erected from the lower portion 20a. And an actuating member 20 provided with a nozzle head 20c provided with a nozzle 50 projecting outwardly at the upper end of the intermediate cylindrical portion 20b.
The operation member 20 is moved up and down with respect to the cylinder member 14 so that the liquid sucked from the container body 100 and the air introduced from the air introduction path A are mixed and discharged from the nozzle head 20c as bubbles,
The nozzle head 20c is formed so that the discharge port 54 of the nozzle 50 is opened downward, and the shape of the foam on the surface of the discharge target H facing the discharge port 54 corresponds to the shape of the discharge port 54. In the foam dispenser formed as
Between the mounting member 2 and the nozzle head 20c, there is provided a stopper piece 62 that can be inserted in a locked state and an unlocked state of the nozzle head 20c, and outward from the stopper piece 62 on the same side as the nozzle 50. A stopper member 60 formed by projecting a mounting table 68 for mounting the discharge target;
The mounting table 68 is separated from the discharge port 54 of the nozzle 50 in the unlocked state, and is formed so that the discharged object can be positioned by placing the discharged object on the mounting table 68.

  In this means, as shown in FIG. 1 or FIG. 6, it is proposed that a stopper member 60 that also serves as a mounting table for an object to be discharged is incorporated in the bubble discharger. The stopper member 60 can be assembled to the guide tube portion 9 or the intermediate tube portion 20b of the actuating member 20 in either a locked state where the nozzle head 20c cannot be pushed down or an unlocked state where the nozzle head 20c can be pushed down. It is possible to perform the function of the stopper in the former state, and the function of the mounting table for the discharged object in the latter state.

The “subject to be ejected” refers to a target for ejecting bubbles from a nozzle, and may be a part of a human body such as a palm, or may be an article.
In this specification, the “intermediate tube portion” of the operating member refers to a portion that can be moved up and down in the guide tube portion 9 of the mounting member, and the mounting tube portion of the head member 40 of the operating member 20 as in the illustrated example. When 44 can be moved up and down in the guide tube portion 9, it includes the mounting tube portion.
A portion of the head member that does not move up and down in the guide tube is referred to as a “nozzle head”.
The “mounting table” refers to a table that is mounted for determining the height position of the discharge target H.
That is, even if it says "placement", for example, the back of the user's hand only needs to be touched lightly, and it does not have to be a support base having strength to support the weight of the discharged object.
It should be noted that projecting the mounting table “to the same outer side as the nozzle 50” is sufficient if it is projected in the same direction as viewed from above. The mounting table does not need to protrude in parallel with the nozzle. For example, the nozzle may protrude obliquely forward slightly toward the upper side or the lower side, and the mounting table 68 may protrude forward in the horizontal direction.

And the vertical cylindrical portion 25 of the stem 24 are included in the intermediate cylindrical portion 20b. A portion of the head member 40 that does not move up and down in the guide tube portion 9 is defined as a nozzle head 20c (or an upper portion of the operating member).

In the configuration so far, when the nozzle head 20c is pushed down from the state of FIG. 1, the piston guide 23 and the liquid piston 22 are lowered, so the poppet valve body 18 is also lowered and the first liquid check valve VL1 is closed. Further, when the liquid piston 22 descends with respect to the poppet valve body 18, the third liquid check valve VL3 and the second liquid check valve VL2 open. Then, the high-pressure liquid in the liquid cylinder flows into the gas-liquid mixing chamber R. Further, since the piston guide 23 is lowered relative to the air piston 32 by the depression of the nozzle head 20c, the second air check valve VA2 is opened, and the air in the air cylinder 14a passes through the ventilation channel G. Then, it flows into the gas-liquid mixing chamber R.

When release of the nozzle head 20c is released, the actuating member 20 is raised by the upward biasing force of the coil spring C, the second liquid check valve VL2 is closed, and the poppet valve body 18 in contact with the liquid piston 22 is pulled up. As a result, the first liquid check valve VL1 is opened, the liquid cylinder 14b becomes negative, and the liquid in the container body 100 is sucked. In addition, the liquid piston 22 and the piston guide 23 are raised before the air piston 32, whereby the air check valve VA is closed. Thereafter, the air piston 32 is raised together with the piston guide 23, and the inside of the air cylinder 14a is negative. Compressed and external air is introduced.
Further, by releasing the push-down of the nozzle head 20c, the cylindrical body 21 rises with respect to the air piston 32, whereby the second air check valve VA2 is closed, and the shielding state by the shielding means V is canceled, and Due to the negative pressure in the air chamber K, the outside air is sucked from the air introduction path A into the outside air introduction hole I through between the main partition wall 34 and the auxiliary partition wall 26.

The knob 66 in the illustrated example has a widened portion 66b formed at the tip of a vertical plate portion 66a protruding from the vertical wall portion 64. In the illustrated example, the knob 66 is formed from one end e1 in the vertical direction of the vertical wall 64 to near the other end e2.
The mounting table 68 projects forward from the vertical wall portion 64 so as to face the nozzle 50. The protruding portion from the vertical wall portion 64 is installed near one side in the vertical direction, in the illustrated example, near the other end e2 in the vertical direction, and the stopper member 60 is inverted in the vertical direction as shown in FIGS. Thus, the mounting table 68 is designed to be closer to the discharge port 54 in the locked state, and the mounting table 68 is positioned farther in the unlocked state. In the preferred illustrated example, the mounting table 68 closes the discharge port 54 in the locked state, thereby reducing the risk of liquid leakage. However, the mounting table 68 does not need to close the discharge port 54 in the locked state.
In the illustrated example, the mounting table 68 has the same protrusion length and right and left as the nozzle 50 so that it can substantially cover the tip 50b of the nozzle 50 when viewed from above, as indicated by an imaginary line in FIG. The width is formed. However, these shapes can be changed as appropriate. For example, the mounting table 68 may be in the form of an elongated band or rod. Further, in order to reduce the amount of resin, a thinning hole or a thinning recess may be formed in a part of the wide plate-like mounting table.

Further, in the present invention, in order to maintain the state in which the nozzle 50 and the mounting table 68 protrude in the same direction, rotation stoppers (position regulating means P1, P2) are provided.
Specifically, first, a locking groove 9c into which the engagement protrusion 46 is inserted is formed on the end side of the guide cylinder part 9, and the guide cylinder part is formed by the engagement protrusion 46 and the locking groove 9c. First position restricting means P1 for restricting the circumferential position of the nozzle 50 with respect to 9 is formed (see FIG. 5).
Further, an arcuate (dominant arc) -shaped fitting recess 9b wider than the semicircle as viewed from above is formed over the front half and slightly rearward of the guide tube portion 9, and the plan view C is formed in the fitting recess 9b. By fitting the letter-shaped vertical wall portion 64, the fitting recess 9b and the vertical wall portion 64 form the second position restricting means P2 for restricting the circumferential position of the mounting table 68 with respect to the guide tube portion 9 ( (See FIG. 5).
Since both the position restricting means restrict the circumferential position of the nozzle 50 and the mounting table 68 with respect to the guide tube portion 9, it is designed so that the nozzle 50 and the mounting table 68 protrude in the same direction in advance. Further, it is possible to prevent the nozzle 50 or the mounting table 68 from rotating unexpectedly in the circumferential direction with respect to the guide tube portion 9 and shifting the protruding directions of both.

According to the above configuration, at the position shown in FIG. 1 (first position), the stopper piece 62 is sandwiched between the upper end surface of the guide tube portion 9 and the lower surface of the nozzle head 20c, so that the nozzle head 20c is pushed down. I can't.
As shown in FIG. 4, the stopper member 60 is simply moved from the first position to the second position by changing the stopper member 60 to the position where the stopper member 60 is fitted to the outside of the guide tube portion 9 (second position) and reversing it vertically. Rather than this, the mounting table 68 can be greatly separated from the discharge port 54.
Then, by placing the discharged object H (for example, the palm of the user) on the mounting table 68, the position of the discharged object can be positioned at a position that the designer has assumed in advance, and an appropriate foam can be formed. can get. Moreover, since at least the function of the mounting table and the function of the positioning means are combined, it is more efficient than the case where separate parts are prepared.

  Hereinafter, a foam dispenser with a stopper according to another embodiment of the present invention will be described. In these descriptions, the description of the same configuration as that of the first embodiment is omitted.

6 to 9 show a foam dispenser with a stopper according to a second embodiment of the present invention.
In the present embodiment, the structure of the stopper member 60 is mainly different from that of the first embodiment.
First, the stopper piece 62 of the stopper member 60 has a double vertical wall portion 64 including an inner wall portion 64a and an outer wall portion 64b. Specifically, as shown in FIG. 7B, the corresponding end portions of the inner wall portion 64a and the outer wall portion 64b that are concentrically arranged in a C shape similar to each other when viewed from above are connected to the C-shaped connecting plate portion. 64c. Thus, a storage groove portion d is formed between the inner wall portion 64a and the outer wall portion 64b so as to be recessed from the one end e1 side to the other end e2 side of the stopper piece 62. The storage groove d is a part for storing an outer peripheral wall 48 to be described later in an unlocked state, and has a shape corresponding to a part of the outer peripheral wall 48 in the circumferential direction when viewed from above.
As shown in FIG. 7A, the mounting table 68 has a substrate portion 68a extending at least forward from a position near the one end e1 of the stopper piece 62, and is perpendicular to the front end of the substrate portion. A front plate portion 68c extending forward is formed through a stepped portion 68b extending to the opposite side to the vertical wall portion 64.
The illustrated substrate portion 68a is formed as a C-shaped plate portion extending continuously outward from the connecting plate portion 64c, and has a stepped portion 68b having a circular arc shape in plan view from its front end portion. The connection of the mounting table 68 to the vertical wall portion 64 is made stronger.
In the illustrated example, an abutment rib 70 is attached to an intermediate portion in the width direction of one surface of the C-shaped substrate portion 68a (surface opposite to the vertical wall portion 64). In this manner, in the state shown in FIG. 9, the inner end portion of the base plate portion 68a and the abutting rib 70 are opposed to the inward flange 8 inclined upward and inward from the mounting cylinder portion 4 described above. Since the contact is made at the place, the stability of the mounting table 68 with respect to the inward flange 8 in a state where the discharge target H is mounted on the front plate portion 68c of the mounting table 68 is improved.
In the present embodiment, the widened portion is omitted from the configuration of the knob 66, but a structure in which the widened portion is provided at the tip of the vertical plate portion may be used as in the first embodiment.
In the present embodiment, the single discharge port 54 is formed at the tip of the nozzle 50, but this merely shows that there are various examples of the form of the discharge port, and can be changed as appropriate. .
In the present embodiment, since the stepped portion 68b is included in the configuration of the mounting table 68, unlike the first embodiment, it is possible to lock only by changing the vertical direction at the same mounting location (outer surface of the guide tube portion 9). The state and the unlocked state can be switched.
That is, in the state of FIG. 6, even when the stopper piece 62 is attached to the guide tube portion 9, the position of the front plate portion 68c of the mounting table 68 is increased by the height difference of the stepped portion 68b. It is possible to reach the position of the discharge port 54.
Furthermore, in this embodiment, instead of the engaging protrusion, an outer peripheral wall portion 48 surrounding the mounting cylinder portion 44 is suspended from the top plate 42, and the upper end portion of the mounting cylinder portion 44 and the outer peripheral wall portion 48 is connected. A wall 47 is attached to the back surface of the top plate 42 in a cylindrical shape. A waterproof ring 58 is fixed to the inner surface of the lower end portion of the outer peripheral wall portion 48.
Although a specific structure is not illustrated, for example, a detent as the first position restricting means P1 is provided between the outer peripheral wall portion 48 and the guide tube portion 9.
Further, as a detent that is the second position restricting means P2, engagement protrusions 8a having a substantially C shape as viewed from above are provided on the rear upper surface of the inward flange 8, and these engagement protrusions are shown in FIG. As shown by the imaginary line in FIG. 5, the structure is such that it can come into contact with a substantially C-shaped edge (referred to as an engaging edge 69) of the substrate 68 a of the mounting table 68 in the locked state.
In the present embodiment, the air introduction path A is formed between the guide tube portion 9 and the operating member 20.
The position of the front plate portion 68c becomes lower than the height of the inward flange 8 by turning the stopper member 60 upside down from the state shown in FIG.
In the state of FIG. 7, even if the nozzle head 20 c is pushed down, the lower end of the outer peripheral wall portion 48 abuts against the connecting plate portion 64 c of the vertical wall portion 64, so that the nozzle head 20 c cannot be pushed down.
In the state of FIG. 9, the lower end of the outer peripheral wall portion 48 faces the opening of the storage groove portion d, and when the nozzle head 20 c is pushed downward, the outer peripheral wall portion 48 descends in the storage groove portion d. It is in a non-locking state in which 20c can be pushed down.
The advantages of this embodiment are as follows.
First, as described above, the difference in height of the front plate portion 68c between the locked state and the non-locked state is increased by the height difference of the stepped portion 68b. Can be bigger.
Secondly, since the stopper member 60 is always supported by the guide tube portion 9 of the mounting member 2, even if something unexpectedly collides with the stopper member 60 in the locked state, the operation member 20 is impacted and operated. There is no risk of rattling of the member 20 or the like.
