Description

  The present invention relates to a liquid discharge container.

  2. Description of the Related Art There has been proposed a liquid discharge container that mixes various liquids such as a hand soap, a face wash, a dishwashing detergent, a hairdressing agent, and the like into air and discharges them as foam. For example, Patent Literature 1 discloses a liquid discharge container that discharges a liquid contained in a container body as bubbles when a head portion is pressed. In this liquid discharge container, a plurality of circular discharge ports are discretely arranged at positions corresponding to the vertices and the center of a triangle or a pentagon. In this liquid ejection container, the positions and diameters of the ejection ports are set such that bubbles ejected from the plurality of ejection ports adhere to each other to form a foamed object simulating a character. .

JP 2010-149060 A

  However, as described above, in the case of a liquid discharge container that foams and discharges a liquid, in order to pick up the liquid that has become bubbles, one hand is placed below the discharge port, and the other hand is used. It is necessary to press the head. That is, it is necessary to use both hands.

  In addition, there is a similar problem in a liquid discharge container that discharges a liquid as a liquid instead of a bubble.

  The present invention relates to a liquid discharge container capable of receiving a liquid (foamed or in a liquid state) onto an object to be discharged such as a hand by one-handed operation.

The present invention is a liquid discharge container that discharges a liquid in a foamed state or in a liquid state according to a pressing operation,

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In all the drawings, the same components are denoted by the same reference numerals, and duplicate description will be appropriately omitted.

[First Embodiment]
First, a first embodiment will be described with reference to FIGS.
The downward direction in FIGS. 1, 3, 4, and 5 is downward, and the upward direction is upward. That is, in the case of the present embodiment, the downward direction (downward) is the direction toward the container body 10 as viewed from the liquid ejection head 400, and the opposite direction is the upward direction (upward). In other words, the downward direction (downward) is the direction of gravity in a state where the bottom 14 of the liquid discharge container 100 is placed on a horizontal mounting surface and the liquid discharge container 100 stands on its own.
FIG. 3 shows only the outline of the portion below the break line H in the liquid ejection cap 300.

  As shown in any of FIGS. 1 to 3, the liquid discharge container 100 according to the present embodiment is a liquid discharge container 100 that foams the liquid 101 (FIG. 3) or discharges the liquid 101 in a liquid state according to a pressing operation. is there. The liquid discharge container 100 includes a container body 10 that stores the liquid 101 and a liquid discharge head 400 that discharges the liquid 101 in response to a pressing operation. As shown in FIG. 3, the liquid discharge head 400 is opened upward and discharges the liquid 101 to the outside in response to a pressing operation (for example, the secondary discharge port 53), and a lower side than the discharge port. And a communication path 57 that communicates the space 59 inside the peripheral wall 56 with the space below the liquid discharge head 400, which surrounds the periphery of the discharge port from the position above to the upper position. The peripheral wall 56 is a pressing portion that keeps a constant distance between the discharge port 22 (for example, a hand as shown in FIG. 1) that receives the liquid 101 and the discharge port. In the present embodiment, as described later, a front chamber 21 in which the liquid 101 spreads is provided upstream of a discharge port for discharging to the outside, and the liquid 101 is supplied to the front chamber 21 in response to a pressing operation. It has a discharge port for discharging (as a foam in the embodiment). In the present specification, for convenience, a discharge port discharging to the front chamber 21 may be referred to as a primary discharge port 33, and a discharge port discharging to the outside may be referred to as a secondary discharge port 53.

According to the present embodiment, the liquid discharge container 100 includes the peripheral wall 56 that is a pressing portion that keeps the distance between the discharge target 22 that receives the liquid 101 and the secondary discharge port 53 constant. For this reason, by performing the pressing operation on the peripheral wall 56 by one-handed operation, it is possible to receive the liquid (foamed or in the liquid state) onto the discharge target 22 such as a hand.
Further, since the liquid discharge container 100 is provided with the communication path 57 that allows the space 59 inside the peripheral wall 56 to communicate with the space below the liquid discharge head 400, the air inside the peripheral wall 56 is discharged when the liquid 101 is discharged. Is pushed out into the space below the liquid ejection head 400 through the communication path 57. Accordingly, foreign matters such as water and dust staying in the space 59 inside the peripheral wall 56 and the communication passage 57 can be discharged through the communication passage 57 by being put on the airflow.
Therefore, the liquid ejection head 400 can be kept clean.

In the direction in which the liquid ejection head 400 is pressed by the pressing operation (pressing direction), that is, the direction in which the liquid ejection head 400 is pressed relatively to the container body 10 by the pressing operation, the secondary ejection port 53 is opened. It is the opposite direction to the direction in which it is (upward), that is, the downward direction.
The peripheral wall 56 rises upward at a position away from the secondary discharge port 53 in the outward direction. Thereby, the peripheral wall 56 forms a distance between the secondary discharge port 53 and the discharge target 22. The outward direction (outside) is a direction away from a central axis of the liquid ejection head 400 (a central axis of a later-described cylindrical portion 31 (FIG. 4)) in plan view.
To maintain the distance between the discharge target 22 and the secondary discharge port 53 constant means that the distance between the discharge target 22 and the secondary discharge port 53 at the end stage of the pressing operation is constant with each pressing operation. In this case, the distance between the discharge target 22 and the secondary discharge port 53 is allowed to change between the start stage and the end stage of the pressing operation. For example, the peripheral wall 56 may be constantly crushed or bent by each pressing operation. However, when the distance between the discharge target 22 and the secondary discharge port 53 changes between the start stage and the end stage of the pressing operation, it is preferable that the amount of change in the distance be constant in each pressing operation. In the case of the present embodiment, the entire liquid discharge head 400 is substantially rigid, and the distance between the discharge target 22 and the secondary discharge port 53 is kept constant from the start stage to the end stage of the pressing operation. It has become so.
In addition, maintaining the distance between the discharge target 22 and the secondary discharge port 53 constant means that the discharge target 22 and the secondary discharge port 53 are separated from each other (see FIG. 1). (A state in which the secondary discharge port 53 is not in contact with the secondary discharge port 53). From the start stage to the end stage of the pressing operation, the discharged body 22 and the secondary discharge port 53 are maintained in a separated state.
In the case of the present embodiment, the peripheral wall 56 rotates around the secondary discharge port 53 by 360 degrees. However, the present invention is not limited to this example, and there may be a part where the peripheral wall 56 does not exist around the secondary discharge port 53.
The communication path 57 is disposed radially inward of the peripheral wall 56.

In the present embodiment, as the liquid 101, a hand soap can be mentioned as a representative example, but the liquid 101 is not limited thereto, and the face wash, cleansing agent, dishwashing detergent, hair styling agent, body soap, shaving cream, foundation and cosmetics Various products used in the form of foam, such as skin cosmetics such as liquids, hair dyes, disinfectants, creams applied to foods such as bread, detergents for home use, disinfectants, and detergents for clothing such as partial washing Can be exemplified.
In the present specification, the foamed (foamed) liquid 101 is called a foam, and is distinguished from the non-foamed liquid 101 stored in the container body 10.
The viscosity of the liquid 101 before foaming, that is, the viscosity of the liquid 101 in the container body 10 is not particularly limited, but may be, for example, about 1 mPa · s to 20 mPa · s at 20 ° C. The viscosity of the liquid 101 is measured by a B-type viscometer. As the B-type viscometer, one having a rotor selected according to the viscosity is used. This rotor rotates at a speed of 60 revolutions / minute. The viscosity 60 seconds after the start of rotation of the rotor is measured.

  Examples of the body to be ejected 22 include hands, foods such as bread to which a sponge for cleaning or application, a cream or the like is applied, and the like.

More specifically, the communication path 57 includes an upper opening 571 opening in a space 59 inside the peripheral wall 56 and a lower opening 572 opening in a space below the liquid ejection head 400. Have.
Therefore, when the liquid 101 is discharged, the air inside the peripheral wall 56 flows into the communication path 57 from the upper opening 571 and is discharged from the communication path 57 from the lower opening 572.

In the case of the present embodiment, the lower opening 572 is formed at the lower end of the ejection head main body 410 shown in FIG. The space below the liquid ejection head 400 is the space below the ejection head main body 410 in the case of the present embodiment.
The liquid ejection head 400 includes an ejection head main body 410, and a tubular portion 31 and an outer tubular portion 36, which will be described later. The ejection head main body 410 includes, in addition to the peripheral wall 56, a second member 50, a trapezoidal portion 37, a male screw portion 44, and the like, which will be described later.

In the case of the present embodiment, the peripheral wall 56 is configured to include an inner peripheral wall 56a located inside and an outer peripheral wall 56b surrounding the inner peripheral wall 56a. An upper opening 571 is formed in the inner peripheral wall 56a, and a lower opening 572 is formed in the outer peripheral wall 56b.
The inner peripheral wall 56a and the outer peripheral wall 56b share an upper edge. This upper edge is the upper edge 56c of the peripheral wall 56. The upper edge 56c is formed in an annular shape surrounding the periphery of the secondary discharge port 53 in plan view. The upper edge 56c is disposed above the upper end of the nozzle forming wall 55.

  Since the peripheral wall 56 has the inner peripheral wall 56a and the outer peripheral wall 56b, good strength of the peripheral wall 56 can be obtained. That is, when the peripheral wall 56 is pressed to discharge the liquid from the liquid discharge container 100, the load applied to the peripheral wall 56 from the upper edge 56c can be dispersed between the inner peripheral wall 56a and the outer peripheral wall 56b, so that the peripheral wall 56 has a good load resistance. Property is obtained.

In the case of the present embodiment, the communication passage 57 is disposed radially inward of the outer peripheral wall 56b.
More specifically, the communication path 57 is an annular space including a gap between the inner peripheral wall 56a and the outer peripheral wall 56b, and a gap between the female screw portion 51 and the outer peripheral wall 56b described later.

In the case of the present embodiment, the peripheral wall 56 is configured to include an upper peripheral wall portion 561 located above the secondary discharge port 53 and a lower peripheral wall portion 562 located below the secondary discharge port 53. Have been.
The upper part of the inner peripheral wall 56a and the upper part of the outer peripheral wall 56b constitute an upper peripheral wall part 561, and the lower part of the inner peripheral wall 56a and the lower part of the outer peripheral wall 56b constitute a lower peripheral wall part 562.

In the case of the present embodiment, as shown in FIG. 6, the liquid ejection container 100 has a plurality of upper openings 571 arranged at different positions in the circumferential direction and a plurality of upper openings 571 arranged at different positions in the circumferential direction. And a lower opening 572. Here, the circumferential direction is a direction around an axis centered on the central axis of the liquid ejection head 400, and is, for example, a direction around an axis centered on a central axis of a tubular portion 31 described later.
Then, as shown in FIG. 6, the upper opening 571 and the lower opening 572 are arranged at positions shifted from each other in the circumferential direction. For this reason, when the air inside the peripheral wall 56 is discharged to the space below the liquid ejection head 400 through the communication path 57, an airflow can be formed over a wider area in the communication path 57, Foreign matter in the communication path 57 can be more reliably discharged to the outside.

The plurality of upper openings 571 are arranged at equal intervals (equal angle intervals) in the circumferential direction.
Similarly, the plurality of lower openings 572 are arranged at equal intervals (equal angle intervals) in the circumferential direction.
Although the numbers of the upper openings 571 and the lower openings 572 are not particularly limited, in the case of the present embodiment, the liquid discharge container 100 includes, for example, four upper openings 571 and four lower openings 572. . The upper opening 571 and the lower opening 572 are arranged so as to be shifted from each other by 45 degrees in the circumferential direction.
However, the present invention is not limited to this example, and the deviation angle between the upper opening 571 and the lower opening 572 in the circumferential direction may be another angle. Further, the number of the upper openings 571 and the number of the lower openings 572 may be different from each other.

The shape of the upper opening 571 is not particularly limited, but in the case of the present embodiment, the upper opening 571 is formed to be long in the circumferential direction.
Further, the shape of the lower opening 572 is not particularly limited, but in the case of the present embodiment, the lower opening 572 is formed to be long in the circumferential direction.
The opening area of the upper opening 571 (the total area of the upper opening 571 when there are a plurality of upper openings 571 as in the present embodiment) is smaller than the flow path area of the communication path 57.
Similarly, the opening area of the lower opening 572 (the total area of the lower opening 572 when there are a plurality of lower openings 572 as in the present embodiment) is smaller than the flow path area of the communication path 57. .

The peripheral wall 56 has an inner surface 56d that defines the communication passage 57. On the inner surface 56d of the peripheral wall 56, a plurality of ridges 565 or grooves (extending vertically) extending downward from above (along and along the inner surface 56d) are formed.
Therefore, when the air inside the peripheral wall 56 is discharged to the space below the liquid ejection head 400 through the communication passage 57, an airflow is formed in the communication passage 57 along the ridge 565 or the groove. It can be expected that the foreign matter in the communication path 57 can be more smoothly discharged to the outside.
As shown in FIG. 7, in the case of the present embodiment, a plurality of ridges 565 are formed on the inner surface 56d.
Preferably, the plurality of ridges 565 or grooves are rotationally symmetric with respect to each other.

More specifically, in the case of the present embodiment, each protrusion 565 extends in a direction (oblique direction) including a vertical component and a circumferential component, and furthermore, each protrusion 565 or groove extends The circumferential components in the directions are in the same direction. Therefore, when the air inside the peripheral wall 56 is discharged to the space below the liquid ejection head 400 through the communication passage 57, a spiral airflow (spiral flow) is formed in the communication passage 57. Therefore, it can be expected that a wider range of foreign matter in the communication path 57 can be discharged to the outside.
In particular, as in the present embodiment, when the upper opening 571 and the lower opening 572 are arranged at positions shifted from each other in the circumferential direction, they extend on the inner surface 56d in the same oblique direction. By forming a plurality of protrusions 565 or grooves, it can be expected that a spiral flow is easily formed.
In the case of the present embodiment, as shown in FIG. 7, each ridge 565 has a curved shape in a plan view, but the present invention is not limited to this example, and the ridge 565 or the groove may be in a plan view. It may be linear.

As shown in FIG. 6, the upper opening 571 is shaped and arranged so that the upper opening 571 can be visually recognized in plan view.
For this reason, when cleaning the liquid discharge head 400, the cleaning liquid (water or the like) easily flows into the communication path 57 from the upper opening 571, so that the liquid discharge head 400 can be easily cleaned. .

Although the shape of the container body 10 is not particularly limited, for example, the container body 10 protrudes upward from the body 11, the shoulder 12 connected to the upper end of the body 11, and the center of the shoulder 12. It has a cylindrical mouth-neck portion 13 (FIG. 3) and a bottom portion 14 closing the lower end of the body portion 11. The upper end of the mouth and neck 13 is open.

As described later, the liquid ejection head 400 is attached to, for example, an upper end of a piston guide 80 provided in the pump unit 75 of the cap 200.

As shown in FIG. 3, the cap 200 detaches the liquid 101 and the air by operating the cap member 70 detachably attached to the mouth and neck portion 13 and the pressing operation of the liquid ejection head 400. The pump unit 75 includes a pump unit 75 that sends out bubbles to the mechanism 19 and discharges bubbles from the secondary discharge port 53, and a dip tube 77 that sucks up the liquid 101 in the container body 10 to the pump unit 75. A suction port for sucking the liquid 101 in the container body 10 is formed at the tip of the dip tube 77.
The structure of the pump unit 75 is well known, and a detailed description thereof will be omitted in this specification.

The former mechanism 19 includes a gas-liquid mixing unit 20 in which the liquid 101 and the air delivered by the pump unit 75 are mixed. When the liquid 101 and the air are mixed in the gas-liquid mixing section 20, the liquid 101 foams (bubbles are generated).
The pump section 75 includes a liquid valve including a ball valve 90. When a pressing operation is performed on the liquid ejection head 400, the ball valve 90 is pushed up to open the liquid valve, and the liquid 101 flows into the gas-liquid mixing unit 20 (that is, the liquid 101 is sent to the gas-liquid mixing unit 20). It has become.
Further, when the liquid 101 is sent to the gas-liquid mixing unit 20, the pump unit 75 is configured to also send air to the gas-liquid mixing unit 20 in parallel.

Above the ball valve 90, for example, a cylindrical ring member 25 is disposed. The ring member 25 is, for example, a jet ring provided in a well-known foam discharge container, and is disposed inside a tubular portion 31 described later in a posture in which the axial direction of the ring member 25 extends vertically.

An opening is formed in the center of the lower component 38 so as to vertically penetrate the lower component 38. The inner peripheral edge of the opening and the lower end of the male screw 44 are connected to each other. For this reason, the lower component part 38 is supported by the male screw part 44.
More specifically, below the lower end of the male screw portion 44, an opening at the center of the lower component 38 is arranged. The connecting part that connects the lower component part 38 and the male screw part 44 to each other is formed in a wall shape having dimensions in the vertical direction.
In the case of the present embodiment, a plurality of connecting portions between the lower component portion 38 and the male screw portion 44 are intermittently arranged in the circumferential direction, and a gap between adjacent connecting portions is formed in the lower opening of the communication passage 57. 572.
Therefore, in the case of the present embodiment, the lower opening 572 is opened radially inward of the liquid ejection head 400.

As shown in FIG. 4, the second member 50 forms an opposing portion 52 opposing the trapezoidal portion 37 of the first member 30.
As shown in FIG. 5, for example, the opposing portion 52 includes a plate-shaped portion 52 a formed in a flat plate shape, a nozzle forming wall 55 rising upward from the plate-shaped portion 52 a, and a lower surface of the plate-shaped portion 52 a. And a wall portion 47 formed at the bottom.
The nozzle forming wall 55 is formed in a closed loop shape in plan view. The opening at the upper end of the nozzle forming wall 55 forms the secondary discharge port 53.
On the base end side of the nozzle forming wall 55, for example, an opening having the same shape as the nozzle forming wall 55 penetrates the facing portion 52 vertically. For this reason, the space below the facing portion 52 (the space to be the front chamber 21 described later) and the space above the secondary discharge port 53 are defined by the opening formed in the facing portion 52 and the inside of the nozzle forming wall 55. They communicate with each other via the space and the secondary discharge port 53.
The peripheral edge of the plate portion 52a of the facing portion 52 is a thin portion 95 formed thinner than the central portion 96 of the plate portion 52a. The upper surface of the thin portion 95 is located lower than the upper surface of the central portion 96.
The outer diameter of the second member 50, that is, the outer diameter of the thin portion 95 is larger than the inner diameter of the annular base 35 of the first member 30, and in the present embodiment, the outer diameter of the thin portion 95 is outside the annular base 35. It is almost equal to the diameter.
A fitting projection 95a is formed on the outer peripheral surface of the thin portion 95. The fitting projection 95a is, for example, an annular ridge that goes around the thin portion 95. However, the fitting convex portion 95a may be formed intermittently in the circumferential direction of the thin portion 95.

As shown in FIGS. 4 and 5, the third member 110 includes an annular female screw portion 51 that is screwed with the male screw portion 44 of the first member 30, and a female screw portion 51 from the upper end of the female screw portion 51. And an inner flange portion 113 that protrudes radially inward in an inner flange shape.
The inner flange portion 113 is formed with an opening vertically penetrating the inner flange portion 113. The upper portion of the opening is an upper opening portion 111 having a smaller inner diameter than the lower opening portion 112, and the lower portion of the opening is an opening lower portion 112 having a larger inner diameter than the upper opening portion 111.
A fitting recess 112 a into which the fitting protrusion 95 a of the thin portion 95 of the second member 50 fits is formed on the inner peripheral surface of the lower opening portion 112.

The third member 110 further includes an inner peripheral wall 56a and an upper component 115, each of which forms a part of the peripheral wall 56.
The inner peripheral wall 56a is an annular wall-like portion that rises upward from the female screw portion 51.
The upper component 115 is a ring-shaped wall extending downward from the upper edge of the inner peripheral wall 56a, and is disposed around the inner peripheral wall 56a. The upper constituent part 115 is a part constituting the upper part of the outer peripheral wall 56b of the peripheral wall 56.
More specifically, the inner peripheral wall 56a is inclined such that the upper part of the inner peripheral wall 56a is located radially outward. More specifically, the inner peripheral wall 56a is formed, for example, in a shape convexly curved outward in a radial direction and obliquely downward.
The upper component 115 is inclined so that the lower part of the upper component 115 is located radially outward. More specifically, the upper component 115 is formed, for example, in a shape convexly curved outward in a radial direction and obliquely upward.
The inner peripheral wall 56a and the upper component 115 share an upper edge with each other. This upper edge is the upper edge 56c of the peripheral wall 56.
Here, since the inner peripheral wall 56a and the upper component 115 are inclined in opposite directions, the load applied to the peripheral wall 56 from the upper edge 56c can be more appropriately distributed to the inner peripheral wall 56a and the outer peripheral wall 56b.

An upper opening 571 penetrating the inside and outside of the inner peripheral wall 56a is formed in the inner peripheral wall 56a. The upper opening 571 allows the space 59 inside the inner peripheral wall 56a and the space outside to communicate with each other. More specifically, upper openings 571 are respectively formed at a plurality of locations in the circumferential direction of the inner peripheral wall 56a.
In the inner peripheral wall 56a, a portion between the adjacent upper openings 571 is a columnar portion 563 connecting the upper portion of the inner peripheral wall 56a and the female screw portion 51.
A fitting portion 115a that fits with the fitting portion 38a of the lower component portion 38 is formed at the lower edge of the upper component portion 115. An inner peripheral portion of the fitting portion 115a is a downwardly projecting annular convex portion, and an outer peripheral portion of the fitting portion 115a is an annular concave portion.

The liquid ejection head 400 is configured by assembling the first member 30, the second member 50, and the third member 110 with each other as described below.
First, the second member 50 is removably mounted on the third member 110 by fitting the thin portion 95 of the second member 50 into the lower opening 112 of the third member 110.
In the state where the second member 50 is mounted on the third member 110, the fitting projection 95a of the thin portion 95 and the fitting recess 112a of the lower opening 112 are fitted, and the upper part of the central part 96 is the upper opening 111. (For example, fits). The upper surface of the central portion 96 and the upper surface of the inner flange portion 113 are flush with each other. Further, an inner peripheral wall 56 a is arranged around the nozzle forming wall 55 and the secondary discharge port 53 of the second member 50.
Next, the second member 50 and the third member 110 are detachably attached to the first member 30 by screwing the female screw portion 51 of the third member 110 and the male screw portion 44 of the first member 30. Installing.
In this state, the fitting part 115a of the upper constituent part 115 and the fitting part 38a of the lower constituent part 38 are fitted together, and the upper constituent part 115 and the lower constituent part 38 are arranged vertically continuously. You. Thus, the outer peripheral wall 56b of the peripheral wall 56 is constituted by the upper component 115 and the lower component 38. That is, the inner peripheral wall 56a, the upper component 115, and the lower component 38 form the peripheral wall 56.
In this state, the lower surface of the plate-shaped portion 52a is in contact with the upper surface of the annular base 35, and a clearance is formed between the lower surface of the plate-shaped portion 52a and the upper surface of the trapezoidal portion 37. This clearance constitutes the front chamber 21 in which the liquid 101 discharged from the primary discharge port 33 (as bubbles in the present embodiment) spreads. The front room 21 is surrounded by an annular base 35. The upright cylinder portion 45 is arranged in the front room 21.
Thus, the liquid ejection head 400 is assembled by three parts.

  In the case of the present embodiment, the upper peripheral wall portion 561 is configured by an upper portion of the inner peripheral wall 56a and a portion excluding the lower end portion of the upper component 115, and the lower peripheral wall portion 562 is formed by a lower portion of the inner peripheral wall 56a. , The lower component of the upper component 115 and the lower component 38.

Here, at the lower end of the outer peripheral surface of the upper component 115 and at the upper end of the outer peripheral surface of the lower component 38, the marking portions 58 (FIGS. 1 and 2) for alignment are respectively formed.
For example, when the screwing of the female screw part 51 of the third member 110 and the male screw part 44 of the first member 30 is completed normally, that is, the third member 110 is normally attached to the first member 30. In this state, the respective marking portions 58 are arranged such that the marking portion 58 of the upper component portion 115 and the marking portion 58 of the lower component portion 38 are aligned vertically.
In the example of FIG. 1 and FIG. 2, the shape of each of the marking portions 58 is triangular, and one vertex of each of the marking portions 58 is placed in a state where the third member 110 is normally attached to the first member 30. It is in a state of being abutted against each other.
The shape of the marking part 58 is not limited to this example. For example, in a state where the third member 110 is normally attached to the first member 30, the marking part 58 straddles the upper constituent part 115 and the lower constituent part 38. Alternatively, a predetermined pattern (for example, a floral pattern or a face) may be completed.

As shown in FIG. 4, the space 59 inside the peripheral wall 56 communicates with a space above the liquid ejection head 400 via an opening 56 e at the upper end of the peripheral wall 56.
It is preferable that at least a part of the upper opening 571 is formed below the secondary discharge port 53. Accordingly, foreign matters such as water and dust remaining below the secondary discharge port 53 (e.g., on the upper surface of the plate portion 52 a) are discharged to the lower side of the liquid discharge head 400 via the communication path 57. Easier to do. In the case of the present embodiment, the upper opening 571 is disposed at the lower end of the inner peripheral wall 56a. For this reason, the foreign matter staying below the secondary discharge port 53 can be more easily discharged through the communication path 57.
In the case of the present embodiment, there is no step between the upper surface of the plate-shaped portion 52a and the upper opening 571, and foreign matter on the upper surface of the plate-shaped portion 52a can be more easily discharged through the communication path 57.

Here, as shown in FIG. 3, the pump unit 75 includes a piston guide 80 formed in a cylindrical shape. The piston guide 80 holds a ball valve 90 at its upper end.
For example, the liquid ejection head 400 pushes the cylinder 31 of the liquid ejection head 400 into the upright cylinder 73 from above the upright cylinder 73, and inserts and fixes the upper end of the piston guide 80 to the lower end of the cylinder 31. By doing so, it is mounted on the piston guide 80. Thus, the liquid discharge head 400 is held by the piston guide 80.
The fixing of the piston guide 80 to the cylindrical portion 31 of the liquid ejection head 400 is performed by, for example, fitting. By strongly pulling the liquid discharge head 400 upward, the fitting of the piston guide 80 to the cylindrical portion 31 is released, and the liquid discharge head 400 can be removed from the cap 200.

The piston guide 80 is supported by a case of the pump unit 75 via an urging member such as a coil spring.
When a pressing operation is performed on the liquid ejection head 400, the liquid ejection head 400 and the piston guide 80 are integrally lowered against the urging of the urging member. The pressing operation of the liquid ejection head 400 stops at a predetermined bottom dead center.
When the pressing operation on the liquid discharge head 400 is released, the liquid discharge head 400 and the piston guide 80 rise to the top dead center position (the position in FIGS. 1 to 3) according to the urging of the urging member. .
The liquid discharge container 100 discharges a certain amount of bubbles by a single pressing operation (operation of pressing the liquid discharge head 400 from top dead center to bottom dead center) on the liquid discharge head 400.

By fixing the piston guide 80 and the liquid ejection head 400 to each other, the ring member 25 (the ring member 25 incorporates the mesh holding ring 23) is disposed above the ball valve 90.
Therefore, the arrangement region of the ball valve 90 communicates with a portion of the flow path 43 in the cylindrical portion 31 above the holding portion 32 through the internal space of the ring member 25 and the mesh holding ring 23, and thus the cylindrical portion 31. Communicates with the primary discharge port 33 at the upper end of the upper end.
When a pressing operation is performed on the liquid discharge head 400, bubbles generated by the former mechanism 19 are discharged upward from the primary discharge port 33 via the cylindrical portion 31.

  By the pressing operation on the liquid ejection head 400, the liquid 101 (in the case of the present embodiment, the foamed liquid 101) causes the primary ejection port 33, the front chamber 21, the internal space of the nozzle forming wall 55, and the secondary ejection port. The liquid passes through 53 in this order and is discharged into a space 59 inside the peripheral wall 56, and adheres to the discharge target 22 such as a hand through the space 59.

The planar shape of the secondary discharge port 53 is not particularly limited. When the planar shape of the secondary discharge port 53 is circular, a circular bubble can be discharged. Further, even when the planar shape of the secondary discharge port 53 is non-circular, it is possible to discharge bubbles having a shape corresponding to the planar shape.
That is, the secondary discharge port 53 is formed in a shape corresponding to the target shape of the foam.
Further, the secondary discharge port 53 may be constituted by an opening at the tip (upper end) of one nozzle forming wall 55 (that is, one (single) opening), or the tip of a plurality of nozzle forming walls 55. A set of (upper end) openings (that is, a set of a plurality of openings arranged independently of each other) may be used.
Further, the shape of the secondary discharge port 53 is not always the same as the target shape of the foam. In order to form a specific three-dimensional bubble, the secondary discharge port 53 must have a non-circular shape or include a plurality of openings (a plurality of openings arranged independently of each other). Is preferred.

  In the case of the present embodiment, the secondary discharge port 53 discharges the foam after shaping the foam into a predetermined target shape. Here, shaping the foam into a predetermined target shape refers to shaping the foam into a non-circular shape. Therefore, in the case of the present embodiment, the bubbles discharged from the secondary discharge ports 53 are formed in a predetermined target shape, and the bubbles have a non-circular shape. A bubble having a non-circular shape means that the planar shape of the bubble is non-circular. The non-circle referred to here does not include a single circle, but includes a shape in which a plurality of circles are gathered and a predetermined target shape described below. As the predetermined target shape of the foam, for example, a triangle, a square, a diamond, a star, a heart shape of a playing card, a clover shape, a spade shape, or a whole body of an animal such as a rabbit, a cat, an elephant, a bear, or a game character, Shapes imitating the outline of a part of the body such as the face, flowers and plants, their fruits, and shapes imitating the outlines of vehicles such as airplanes, automobiles, and yachts are exemplified.

In the case of the present embodiment, the predetermined target shape of the bubble is a shape imitating a flower.
As shown in FIG. 2, the secondary discharge port 53 and the nozzle forming wall 55 correspond to bubbles having such a shape.
The secondary discharge port 53 includes a plurality (for example, five) of openings formed at the tip of a plurality (for example, five) of the nozzle forming walls 55.
The opening at the tip of each nozzle forming wall 55 has a planar shape in which bubbles discharged from the openings are shaped like individual petals, and these openings are arranged radially.
As shown in FIG. 1, by pressing the peripheral wall 56, which is a pressing portion, by the discharge target 22 such as a palm, bubbles discharged from each opening are integrated into the palm to form a flower-like shape. , Bubbles stick to palm.

More specifically, it is preferable that the formation range of the front chamber 21 be limited by the wall 47 formed on the lower surface of the plate-shaped portion 52a. That is, in the case of the present embodiment, the front chamber 21 is formed at an interval between the lower surface of the plate-shaped portion 52a and the upper surface of the trapezoidal portion 37, and is formed in an annular shape with the wall 47 formed on the lower surface of the plate-shaped portion 52a. This is an area surrounded by the table 35.
For example, when a plurality of secondary discharge ports 53 are radially arranged as in the present embodiment, the front chamber 21 extends along the periphery of the secondary discharge ports 53 as shown in FIG. In addition, it is preferably formed so as to include the secondary discharge port 53, and in the present embodiment, it is formed in a star shape (starfish shape).
Thereby, the response time from when the liquid ejection head 400 is pressed to when the liquid 101 (bubbles in the present embodiment) is ejected from the secondary ejection port 53 can be reduced.

Next, the operation will be described.
In a normal state where the liquid ejection head 400 is not pressed, the liquid ejection head 400 is located at the top dead center position.
As shown in FIG. 1, the pressing operation on the liquid discharge head 400 is performed in a state where the discharge target 22 such as a hand closes the opening 56e of the upper end (the upper edge 56c of the peripheral wall 56) of the liquid discharge head 400 (that is, the discharge target). The liquid discharge head 400 can be pressed by the discharge target 22 in a state in which the liquid discharge head 400 faces the secondary discharge port 53 via the space 59).

When the pressing operation on the liquid ejection head 400 is performed, the liquid ejection head 400 and the piston guide 80 are lowered relatively to the container body 10 against the urging of the urging member in the pump unit 75.
At this time, the liquid 101 and the air are supplied to the gas-liquid mixing unit 20 by the action of the pump unit 75, and bubbles are generated in the gas-liquid mixing unit 20. The bubbles generated in the gas-liquid mixing unit 20 become finer and more uniform by passing through the mesh 24. The foam generated by the former mechanism 19 in this manner passes through the inside of the cylindrical portion 31 and is discharged from the primary discharge port 33 to the front chamber 21 and spreads in the front chamber 21.
Further, the bubbles pass through the nozzle forming wall 55 formed in the facing portion 52 and are discharged from the secondary discharge port 53. The bubbles are shaped into a predetermined target shape (a shape imitating a flower in this embodiment) by passing through the nozzle forming wall 55 and the secondary discharge port 53, and are formed on the lower surface of the discharge target 22 closing the opening 56e. Adhere to. That is, the foam that has popped out of the secondary discharge port 53 by the pressing operation on the peripheral wall 56 is transferred to the discharged body 22, and the foam molded article that is the foam shaped into a predetermined target shape adheres to the lower surface of the discharged body 22. State.
Thereafter, when the pressing operation on the liquid ejection head 400 is released, the piston guide 80 and the liquid ejection head 400 move up according to the urging of the urging member, and the liquid ejection head 400 returns to the top dead center position.
Thereafter, the ejected body 22 is lifted above the opening 56e and turned over, so that a foamed object is formed on the ejected body 22. That is, the foam molded article having a predetermined target shape can be received on the discharge target 22.
When the piston guide 80 moves up, the liquid 101 in the container body 10 is sucked into the pump unit 75 via the dip tube 77.
The structure and operation of the cap 200 (including the pump unit 75) described here are merely examples, and the structure of the cap 200 may be any other widely known structure without departing from the spirit of the present invention. There is no problem at all even if one is applied to this embodiment.

The height difference between the upper surface of the plate-shaped portion 52a and the upper edge 56c of the peripheral wall 56, that is, the peripheral wall 56 based on the upper surface of the plate-shaped portion 52a, so that the foamed object can be suitably received on the discharge target 22. Is preferably at least twice the height difference between the upper surface of the plate portion 52a and the upper end of the nozzle forming wall 55, that is, at least three times the height of the nozzle forming wall 55. More preferably, it is preferably 10 times or less, more preferably 8 times or less.
The height difference between the secondary discharge port 53 and the upper edge 56c of the peripheral wall 56 is preferably 5 mm or more and 20 mm or less, more preferably 7 mm or more and 18 mm or less.
In addition, the height dimension of the nozzle forming wall 55 is preferably 1 mm or more, and more preferably 2 mm or more, from the viewpoint of enabling the bubbles to be satisfactorily received from the secondary discharge port 53 onto the body 22 to be discharged. It is preferably 10 mm or less, more preferably 8 mm or less.
Further, when a pressing operation is performed on the peripheral wall 56 without disposing the body 22 at a position facing the secondary discharge port 53, bubbles discharged from the secondary discharge port 53 cause the upper edge of the peripheral wall 56 to move. It is preferable that the structure of the former mechanism 19 such as the pump unit 75 and the height dimension of the peripheral wall 56 and the nozzle forming wall 55 be set so as to protrude upward from 56c.

  When the liquid discharge head 400 is pushed down at a speed of 30 mm / s from the viewpoint of smoothly discharging bubbles from the secondary discharge port 53 and stably forming bubbles of a specific shape on the discharge target 22 such as a hand. Is preferably 1 N or more, more preferably 5 N or more, further preferably 40 N or less, further preferably 35 N or less.

  Since the foam spreads in the front chamber 21 disposed in front of the secondary discharge port 53 and fills the front chamber 21 with the foam, the foam can be discharged from the secondary discharge port 53. It is easy to sufficiently spread the entire area of the next discharge port 53, and it is easy to form bubbles into a predetermined target shape by the secondary discharge port 53. Further, by disposing the facing portion 52, bubbles discharged from the primary discharge port 33 are easily spread in the front chamber 21.

  Further, since the liquid discharge container 100 includes the upright cylindrical portion 45, it is possible to suppress foreign matter such as dust from entering the flow channel 43 through the secondary discharge port 53, the front chamber 21, and the primary discharge port 33. . Therefore, it is possible to reduce the influence of the foreign matter on the discharge property of the liquid 101 due to the clogging of the former mechanism 19 and the flow path 43.

Further, as described above, when the liquid 101 is discharged, the air inside the peripheral wall 56 is pushed out to the space below the liquid discharge head 400 via the communication path 57, and thus the space 59 inside the peripheral wall 56 is discharged. And the foreign matter staying in the communication path 57 can be discharged.
Here, since the secondary discharge port 53 is formed at the upper end of the nozzle forming wall 55 rising upward from the plate-shaped portion 52a, it is possible to suppress the interference of bubbles near the upper surface of the plate-shaped portion 52a. For this reason, foreign substances on the plate-shaped portion 52a can also be discharged.
Further, when the liquid 101 is discharged, the air is instantaneously compressed in the space 59 and the communication path 57, so that the foreign matter can be vigorously discharged through the communication path 57.

  Furthermore, when the liquid 101 is discharged, the air is instantaneously compressed in the space 59 and the communication path 57, so that the bubbles are instantaneously pressurized and then released to the atmospheric pressure. Can be expected.

Here, the volume (unit bubble volume) of the foam discharged by one foam discharging operation is not particularly limited, but is, for example, preferably ³ cm ³ or more and 30 cm ³ or less, and more preferably 5 cm ³ or more and 20 cm ³ or less. More preferably, it is more preferably 10 cm ³ or more.
The total volume of the volume of the volume and the communication path 57 of the space 59 is not particularly limited, but is preferably 10 cm ³ or more 200 cm ³ or less, and further preferably 20 cm ³ or more 100 cm ³ or less.
The opening area of the lower opening 572 (the total area of the lower opening 572) is not particularly limited, but is preferably 1 cm ³ or more and 10 cm ³ or less, and is preferably smaller than the unit bubble volume.
By satisfying these conditions, it can be expected that the speed of the airflow formed in the communication path 57 at the time of discharging the liquid 101 can be sufficiently secured.
Further, the total area of the lower opening 572 is preferably larger than the total area of the upper opening 571. By doing so, the discharge property of foreign matter is further improved.

According to the first embodiment described above, the liquid discharge head 400 of the liquid discharge container 100 includes the peripheral wall 56 surrounding the secondary discharge port 53 and the space 59 inside the peripheral wall 56 as the liquid discharge head. The peripheral wall 56 is a pressing portion that maintains a constant distance between the discharge target body 22 that receives the liquid 101 and the secondary discharge port 53.
Therefore, by performing a pressing operation on the peripheral wall 56 with the discharged body 22 such as a hand, bubbles discharged from the secondary discharge port 53 can be attached to the discharged body 22. Therefore, it is possible to receive the liquid 101 (bubbles in the present embodiment) on the discharge target 22 such as a hand by one-handed operation. That is, the bubbles can be received on the body 22 by a simple operation.
Further, since the distance between the discharge target 22 and the secondary discharge port 53 can be kept constant by the peripheral wall 56, the bubbles discharged from the secondary discharge port 53 are not crushed by the discharge target 22 and the discharge It can be received on the body 22.
Therefore, in particular, when the foam is shaped and discharged in a predetermined target shape, it becomes easier to more accurately form the bubble in the target shape on the discharge target 22.
In addition, since the secondary discharge port 53 is formed at the tip of the nozzle forming wall 55, the bubbles can be stably discharged toward the discharge target 22, and the bubbles are discharged from the secondary discharge port 53. (Separation of bubbles from the secondary discharge port 53) can be improved.
Further, since the upper edge 56c of the peripheral wall 56 is located above the nozzle forming wall 55, the bubbles can be suitably received on the discharge target 22 without crushing the bubbles.
Further, when the liquid 101 is discharged, the air inside the peripheral wall 56 is pushed out to the space below the liquid discharge head 400 via the communication path 57, and thus stays in the space 59 and the communication path 57. Foreign matter can be discharged through the communication path 57.
Further, since the liquid ejection head 400 includes the peripheral wall 56, the degree of freedom in designing the liquid ejection head 400 is increased.

In the case of the present embodiment, the liquid discharge head 400 includes three members, a first member 30, a second member 50, and a third member 110. As shown in FIG. Since the members can be separated, cleaning of these members becomes easier.
Further, as described above, since the second member 50 is attached by being fitted to the third member 110, the second member 50 is separated from the first member 30 when the third member 110 is separated from the first member 30. Are kept integrated with the third member 110. Therefore, the third member 110 and the second member 50 can be washed together with the third member 110 and the second member 50 removed from the first member 30.

[Second embodiment]
Next, a second embodiment will be described with reference to FIGS. The liquid discharge container according to the present embodiment (all not shown) is different from the liquid discharge container 100 according to the above-described first embodiment in having a lid member 120 and a ridge 123 described below, respectively. In other respects, the configuration is the same as that of the liquid ejection container 100 according to the first embodiment.

The lid member 120 is mainly used when the liquid discharge container 100 (typically, the liquid discharge container 100 filled with the liquid 101 and in the form of the liquid filling container 800) is distributed (including when the liquid discharge container 100 is displayed for sale) or stored. At times, it is used to restrict entry of foreign matter into the space 59.
The lid member 120 includes, for example, a flat lid main body 121 and a tongue-shaped knob 122 connected to an edge of the lid main body 121.
The cover member 120 is provided detachably with respect to the liquid ejection head 400.

The lid main body 121 is formed, for example, in a disk shape capable of closing the upper end of the space 59.
The knob 122 is disposed so as to be bent upward with respect to the lid main body 121 with the lid member 120 provided on the liquid ejection head 400.
