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

[First Embodiment]
First, the first embodiment will be described with reference to FIGS. 1 to 5.
In addition, in FIG. 1, FIG. 3, FIG. 4 and FIG. 5, the downward direction is downward and the upward direction is upward. That is, in the case of the present embodiment, 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 is self-supporting.
In FIG. 3, only the outline is shown for the portion of the liquid discharge cap 300 below the break line H.

As shown in any one of FIGS. 1 to 5, the liquid discharge container 100 according to the present embodiment is a liquid discharge container 100 that foams or discharges the liquid 101 (FIG. 3) in response to a pressing operation. is there. The liquid discharge container 100 includes a container body 10 for storing the liquid 101 and a liquid discharge head 400 for discharging the liquid 101 in response to a pressing operation. The liquid discharge head 400 is open in the direction opposite to the pressing direction (downward in the present embodiment) (upward in the present embodiment) with the primary discharge port 33 for discharging the liquid 101 in response to the pressing operation. The distance between the secondary discharge port 53 that discharges the liquid 101 discharged from the discharge port 33 to the outside, the discharged body 22 that receives the liquid 101 (for example, a hand as shown in FIG. 1), and the secondary discharge port 53. It has a pressing portion 56 for maintaining a constant value, and a front chamber 21 formed between the primary discharge port 33 and the secondary discharge port 53 and in which the liquid 101 discharged from the primary discharge port 33 spreads. In the front chamber 21, an upright tubular portion 45 that surrounds the primary discharge port 33 and stands up toward the secondary discharge port 53 is arranged. Here, the direction opposite to the pressing direction is also the discharge direction of the liquid from the secondary discharge port 53.

According to the present embodiment, since the liquid discharge container 100 includes a pressing portion 56 that maintains a constant distance between the discharged body 22 that receives the liquid 101 and the secondary discharge port 53, the liquid can be discharged by one-handed operation. It can be received on the ejected body 22 such as a hand (whether it is foamed or remains liquid). Further, the standing cylinder portion 45 that surrounds the primary discharge port 33 and stands up toward the secondary discharge port 53 makes it difficult for foreign matter such as dust and dirt to enter the primary discharge port 33, and is affected by the discharge property of the liquid 101. Hateful.

More specifically, the liquid discharge head 400 includes a first member 30 having a primary discharge port 33 and a second member 50 having a secondary discharge port 53, and the second member 50 has a second member 50 with respect to the first member 30. It is attached detachably.
Since the second member 50 having the secondary discharge port 53 is detachably attached to the first member 30 having the primary discharge port 33, the second member 50 can be easily removed from the first member 30 and cleaned easily. can do.

The liquid discharge head 400 includes a pressing portion 56. The pressing portion 56 has an upright portion that stands up at a position separated from the secondary discharge port 53 in the outward direction. The pressing portion 56 has an upright portion to form a distance between the secondary discharge port 53 and the discharged body 22. The pressing direction is a direction in which the liquid discharge head 400 is pressed relative to the container body 10 by the pressing operation. The outward direction (outside) is a direction away from the central axis of the standing cylinder portion 45 when the liquid discharge head 400 is viewed from above.
In the present embodiment, since the direction in which the liquid discharge head 400 is pressed by the pressing operation is downward, the pressing operation may be referred to as a pressing operation of the liquid discharge head 400.
Here, the pressing direction and the direction opposite to the pressing direction do not necessarily have to be 180 degrees different on the same straight line, and may be approximately opposite directions. Therefore, a certain degree of axial deviation (for example, axial deviation within 10 degrees) is allowed between the pressing direction and the direction opposite to the pressing direction.
Further, maintaining a constant distance between the discharged body 22 and the secondary discharge port 53 means that the distance between the discharged body 22 and the secondary discharge port 53 at the end stage of the pressing operation is constant with each other in each pressing operation. It is permissible that the distance between the ejected body 22 and the secondary ejection port 53 changes between the start stage and the end stage of the pressing operation. For example, the pressing portion 56 may be constantly crushed or bent by each pressing operation. However, when the distance between the ejected body 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 is constant with each other 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 discharged body 22 and the secondary discharge port 53 is maintained constant from the start stage to the end stage of the pressing operation. It has become so.
Further, maintaining a constant distance between the discharged body 22 and the secondary discharge port 53 means that the discharged body 22 and the secondary discharge port 53 are separated from each other (with the discharged body 22), as can be seen from FIG. It is to maintain the 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.

The liquid discharge container 100 includes a container body 10 and a liquid discharge cap 300 that is detachably attached to the container body 10. In other words, the liquid discharge cap 300 is composed of a portion of the liquid discharge container 100 excluding the container body 10.

As described above, the liquid discharge cap 300 is used by being attached to the container body 10, and is a liquid discharge cap 300 that foams or discharges the liquid 101 in response to a pressing operation, and is the above-mentioned primary discharge port. It has 33, a secondary discharge port 53, and a pressing portion 56, and also includes a first member 30 and a second member 50.

In other words, the liquid discharge head 400 is composed of a portion of the liquid discharge cap 300 excluding the cap 200.

As described above, the liquid discharge head 400 is used by being attached to the cap 200 attached to the container body 10 for storing the liquid 101, and the liquid 101 is foamed or discharged in the liquid state according to the pressing operation. The head 400 has the above-mentioned primary discharge port 33, secondary discharge port 53, and pressing portion 56, and also includes a first member 30 and a second member 50.

That is, when the liquid discharge head 400 is attached to the cap 200 and the cap 200 is attached to the container body 10, a pressing operation is performed on the liquid discharge head 400, so that the liquid discharge head 400 becomes the liquid 101. Is discharged.
As will be described later, the liquid discharge head 400 is attached to, for example, the upper end of the piston guide 80 included in the pump portion 75 of the cap 200.

In the present embodiment, hand soap can be mentioned as a typical example of the liquid 101, but the liquid 101 is not limited to this, but is not limited to this, and is not limited to this, but is not limited to this, but is not limited to this, but is not limited to this, and is not limited to this. Various skin cosmetics such as liquids, hair dyes, disinfectants, creams applied to foods such as bread, household detergents, disinfectants, and laundry detergents for partial washing, etc. Can be exemplified.
In the present specification, the foamy (foamed) liquid 101 is referred to as a foam to distinguish it from the non-foamable 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 can be, for example, about 1 mPa · s or more and 20 mPa · s or less at 20 ° C. The viscosity of the liquid 101 is measured with 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 rotation speed of 60 rotations / minute. The viscosity is measured 60 seconds after the start of rotation of the rotor.

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

The shape of the container body 10 is not particularly limited, but the container body 10 projects upward from, for example, the body portion 11, the shoulder portion 12 connected to the upper end of the body portion 11, and the central portion of the shoulder portion 12. It has a cylindrical mouth and neck portion 13 (FIG. 3) and a bottom portion 14 that closes the lower end of the body portion 11. The upper end of the mouth and neck 13 is open.
In the case of the present embodiment, the liquid discharge container 100 can stand on its own with the bottom portion 14 mounted on a horizontal mounting surface. Further, the foamed liquid 101 can be discharged from the secondary discharge port 53 by pressing the liquid discharge head 400 while the liquid discharge container 100 is self-supporting.

In the case of the present embodiment, the liquid discharge container 100 is, for example, a manual pump container (pump former), and the container body 10 stores the liquid 101 at normal pressure. Further, the liquid discharge cap 300 includes a former mechanism 19 that foams the liquid 101.

As shown in FIG. 3, the cap 200 forms a liquid 101 and air by operating in conjunction with a pressing operation of a cap member 70 that is detachably attached to the mouth and neck 13 and a liquid discharge head 400. It is provided with a pump unit 75 that sends out to the mechanism 19 and discharges bubbles from the secondary discharge port 53, and a dip tube 77 for sucking the liquid 101 in the container body 10 into 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 detailed description thereof will be omitted in the present specification.
When the liquid discharge head 400 is pressed, the cap 200 foams the liquid 101 and discharges the bubbles.

The cap member 70 includes a cylindrical mounting portion 71 that is detachably attached to the mouth and neck portion 13 by a fastening method such as screwing, and an annular closing portion 72 that closes the upper end portion of the mounting portion 71. It is provided with an upright tubular portion 73 which is formed in a cylindrical shape having a diameter smaller than that of the mounting portion 71 and which stands upward from the central portion of the annular closing portion 72.
The mounting portion 71 may be formed in a double tubular structure, and the inner tubular portion may be screwed into the mouth neck portion 13 or may be configured in a single tubular shape. You may be. By attaching the attachment portion 71 to the mouth neck portion 13, the entire cap member 70, the entire cap 200, and the entire liquid discharge cap 300 are attached to the container body 10.
When the liquid discharge cap 300 is attached to the container body 10, the liquid discharge cap 300 closes the opening at the upper end of the mouth and neck portion 13.

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

Above the ball valve 90, for example, a tubular ring member 25 is arranged. The ring member 25 is, for example, a jet ring provided in a well-known foam discharge container, and is arranged inside a tubular portion 31 described later in a posture in which the axial direction of the ring member 25 extends vertically.
Inside the ring member 25, for example, a tubular mesh holding ring 23 is provided in two upper and lower stages. A mesh 24 is provided in each of the opening at the lower end of the lower mesh holding ring 23 and the opening at the upper end of the upper mesh holding ring 23.
The internal space of the ring member 25 constitutes, for example, a part of the gas-liquid mixing section 20.
The mesh holding ring 23 and the mesh 24 together with the gas-liquid mixing section 20 form a former mechanism 19.
As the bubbles generated in the gas-liquid mixing section 20 pass through the mesh 24, the bubbles become finer and more uniform.
If the foam of desired fineness can be generated without the mesh 24, the former mechanism 19 does not have to have the mesh holding ring 23 and the mesh 24.

In the case of the present embodiment, the liquid discharge head 400 is composed of, for example, two members, the first member 30 and the second member 50, which will be described below.

As shown in FIGS. 4 and 5, the first member 30 has a cylindrical (circular tubular) tubular portion 31, a trapezoidal portion 34 connected to the upper end of the tubular portion 31, and a peripheral edge of the trapezoidal portion 34. An annular wall 35 that rises upward from the portion and an outer cylinder portion 36 that extends downward from the trapezoidal portion 34 around the cylindrical portion 31 are provided.
Further, the first member 30 includes an upright tubular portion 45 that stands upward from the facing surface 37, which is the upper surface of the trapezoidal portion 34, so as to surround the primary discharge port 33 around the primary discharge port 33. There is.
The standing cylinder portion 45 and the cylinder portion 31 are arranged coaxially with each other, for example.
The upright tubular portion 45 has, for example, a cylindrical shape, and the planar shape of the primary discharge port 33 is, for example, a circular shape.
From the viewpoint of the spreadability of the liquid into the anterior chamber 21, the height of the tip of the standing cylinder portion 45 is preferably 1/2 or less of the height of the anterior chamber 21.
In the first member 30, a flow path 43 that vertically penetrates the first member 30 is formed from a tubular portion 31 to an upright tubular portion 45. On the inner peripheral surface of the flow path 43, for example, a plurality of ribs extending in the longitudinal direction of the flow path 43 may be formed at equal angular intervals in the circumferential direction of the flow path 43. The opening at the upper end of the standing cylinder portion 45, that is, the downstream end of the flow path 43 is the primary discharge port 33.
For example, the annular wall 35 is arranged coaxially with the standing cylinder portion 45.
For example, in the outer cylinder portion 36, the outer diameter of the portion of the outer cylinder portion 36 excluding the upper end portion gradually increases from the lower end to the upper side.
Further, a thread is formed on the outer peripheral surface of the portion from the upper end portion of the outer cylinder portion 36 to the trapezoidal portion 34, and the upper end portion constitutes the male screw portion 44.
The annular wall 35 is formed in an annular shape, for example.

A part of the internal space of the tubular portion 31 of the first member 30 is a holding portion 32 that holds the ring member 25 (FIG. 3).
The ring member 25 that internally holds the upper and lower two-stage mesh holding rings 23 is fixed to the holding portion 32 by being inserted into the tubular portion 31 from the lower end of the tubular portion 31.

The second member 50 has a facing portion 52 facing the facing surface 37 of the first member 30 in a state where the second member 50 is mounted on the first member 30.
In the case of the present embodiment, the facing portion 52 has a plate-shaped portion 52a formed in a flat plate shape, a nozzle forming wall 55 standing upward from the plate-shaped portion 52a, and protruding downward from the plate-shaped portion 52a. The protrusion 65 is provided. The nozzle forming wall 55 is formed in a closed loop shape in a plan view. The opening on the tip side of the nozzle forming wall 55 in the upright direction constitutes the secondary discharge port 53.
Further, 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. Therefore, the space below the facing portion 52 (the space serving as the anterior chamber 21 described later) and the space above the secondary discharge port 53 are the openings formed in the facing portion 52 and the inside of the nozzle forming wall 55. They communicate with each other through the space and the opening at the tip of the nozzle forming wall 55.

The second member 50 further includes a pressing portion 56 projecting upward from the facing portion 52.
That is, in the case of the present embodiment, the second member 50 has the pressing portion 56.
The pressing portion 56 is, for example, a plurality of columnar portions 57 projecting upward (for example, diagonally upward) from the peripheral edge portion (peripheral portion of the plate-shaped portion 52a) of the facing portion 52, and the tip portions of the plurality of columnar portions 57. It is configured to include an annular portion 58 connecting the two.
The annular portion 58 is formed, for example, in an annular shape, and the central axis of the annular portion 58 is orthogonal to the plate surface of the plate-shaped portion 52a. Further, the central axis of the annular portion 58 passes through, for example, the center of the plate-shaped portion 52a.
In other words, the pressing portion 56 stands up from the facing portion 52 at a position separated from the secondary discharge port 53 in the outward direction in the direction opposite to the pressing direction by the pressing operation.
The gap between the adjacent columnar portions 57, which is between the pressing portion 56 and the facing portion 52, is a hole 63 for communicating the inner region and the outer region of the pressing portion 56 with each other. In the case of the present embodiment, the pressing portion 56 has a plurality of holes 63.
Further, an opening 56a is formed at the upper end (annular portion 58) of the pressing portion 56 to allow the liquid 101 discharged from the secondary discharge port 53 to pass to the outside.

The second member 50 further includes an annular wall 51 projecting downward from the peripheral edge of the facing portion 52 (the peripheral edge of the plate-shaped portion 52a). The annular wall 51 is formed in an annular shape, and a screw thread is formed on the inner peripheral wall of the annular wall 51. As a result, the annular wall 51 becomes a female screw portion that is screwed with the male screw portion 44 of the first member 30.
In the case of the present embodiment, the annular wall 51 of the second member 50 is screwed with the male screw portion 44 of the first member 30, so that the second member 50 is detachably attached to the first member 30.

As shown in FIG. 5, when the second member 50 is attached to the first member 30, the tip (upper end) of the annular wall 35 in the upright direction abuts on the lower surface of the peripheral edge of the plate-shaped portion 52a, thereby facing each other. The clearance between the surface 37 and the plate-shaped portion 52a is maintained. This clearance constitutes the anterior chamber 21 in which the liquid 101 discharged from the primary discharge port 33 (as bubbles in the present embodiment) spreads.
That is, in the state where the second member 50 is attached to the first member 30, the front chamber 21 in which the liquid 101 discharged from the primary discharge port 33 spreads is formed between the second member 50 and the first member 30. The liquid.
Then, by pressing the liquid discharge head 400, the liquid 101 (in the case of the present embodiment, the foamed liquid 101) passes through the primary discharge port 33, the anterior chamber 21, and the secondary discharge port 53 to the outside in this order. It is discharged.
More specifically, the anterior chamber 21 is formed between the facing surface 37 of the trapezoidal portion 34 of the first member 30 and the facing portion 52 of the second member 50. The anterior chamber 21 is an area surrounded by an annular wall 35.

In the case of the present embodiment, the second member 50 has an opposing portion 52 arranged so as to face the first member 30 with the front chamber 21 sandwiched between them, and the secondary discharge port 53 is formed in the facing portion 52. The first member 30 has a facing surface 37 which is arranged so as to face the facing portion 52 with the front chamber 21 in between, and the standing cylinder portion 45, and the standing cylinder portion 45 faces each other. It stands up from the surface 37 toward the facing portion 52, and the opening at the tip of the upright cylinder portion 45 in the upright direction is the primary discharge port 33.
In the case of the present embodiment, the facing surface 37 and the plate-shaped portion 52a of the facing portion 52 face each other in parallel.

A part of the protrusion 65 of the facing portion 52 has entered the inside of the standing cylinder portion 45. That is, the facing portion 52 has a protruding portion 65 projecting toward the first member 30 side, and a part of the protruding portion 65 has entered the inside of the standing cylinder portion 45. With such a configuration, it is possible to further suppress the intrusion of foreign matter into the primary discharge port 33.
In the case of the present embodiment, the protrusion 65 is further upstream of the flow path 43 (lower in FIG. 5) than the standing cylinder 45.
The protruding portion 65 is formed, for example, in a hemispherical shape (for example, a hemispherical shape having a rounded tip portion (lower end portion)) and is arranged coaxially with the standing cylinder portion 45. However, there is a clearance between the protrusion 65 and the peripheral wall of the flow path 43 for the liquid 101 to pass through, and the liquid 101 (foam in the present embodiment) that has passed through the flow path 43 passes through this clearance. The liquid flows into the front chamber 21, and is further discharged from the front chamber 21 to the outside through the secondary discharge port 53.

The height dimension of the pressing portion 56 is larger than the height dimension of the nozzle forming wall 55. The height dimension of the pressing portion 56 is the protruding length of the pressing portion 56 upward from the plate-shaped portion 52a, and is also the height difference between the upper surface of the plate-shaped portion 52a and the upper end of the pressing portion 56.
Further, the height dimension of the nozzle forming wall 55 is the protruding length of the nozzle forming wall 55 from the plate-shaped portion 52a, and is also the height difference between the upper surface of the plate-shaped portion 52a and the upper end of the pressing portion 56.
That is, the pressing portion 56 extends beyond the secondary discharge port 53 in the direction opposite to the pressing direction (upward) by the pressing operation.

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, circular bubbles can be discharged. Further, even when the planar shape of the secondary discharge port 53 is non-circular, bubbles having a shape corresponding to the planar shape can be discharged.
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 composed of an opening at the tip of one nozzle forming wall 55 (that is, one (singular) opening), or may be composed of an opening at the tip of a plurality of nozzle forming walls 55. It may be an aggregate (that is, an aggregate of a plurality of openings arranged independently of each other).
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 has a non-circular shape or is configured to include a plurality of openings (a plurality of openings arranged independently of each other). Is preferable.

In the case of the present embodiment, the secondary discharge port 53 shapes the foam into a predetermined target shape and discharges the foam. Here, shaping the foam into a predetermined target shape means shaping the foam into a non-circular shape. Therefore, in the case of the present embodiment, the bubbles discharged from the secondary discharge port 53 are formed in a predetermined target shape, and the bubbles have a non-circular shape. The non-circular shape of a bubble means that the shape of the bubble in a plan view is non-circular. The non-circle referred to here does not include a single circle, but includes an aggregated shape of a plurality of circles and a predetermined target shape described below. Predetermined target shapes of bubbles include, for example, triangles, squares, rhombuses, stars, playing card hearts, clovers, spades, and whole bodies of animals such as rabbits, cats, elephants, bears, and game characters. Examples include a shape that imitates the contour of a part of the body such as a face, a shape that imitates the contour of flowers and plants, and their fruits, and vehicles such as airplanes, automobiles, and yachts.

In the case of the present embodiment, the predetermined target shape of the foam 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 is configured to include a plurality of (for example, five) openings formed at the tips of a plurality of (for example, five) nozzle forming walls 55.
The openings at the tips of the nozzle forming walls 55 have a planar shape imitating individual petals, and these openings are arranged radially.
As shown in FIG. 1, by pressing the pressing portion 56 with the ejected body 22 such as the palm, the bubbles ejected from each opening are integrated in the palm to form a flower-like shape, and the bubbles are formed. Adheres to the palm.

Here, the pump portion 75 includes a piston guide 80 formed in a tubular shape. The piston guide 80 holds the ball valve 90 at its upper end.
For example, the liquid discharge head 400 pushes the cylinder portion 31 of the liquid discharge head 400 into the standing cylinder portion 73 from above the standing cylinder portion 73, and inserts and fixes the upper end portion of the piston guide 80 into the lower end portion of the cylinder portion 31. By doing so, it is attached to the piston guide 80. As a result, the liquid discharge head 400 is held by the piston guide 80.
The piston guide 80 is fixed to the tubular portion 31 of the liquid discharge head 400 by, for example, fitting. By strongly pulling the liquid discharge head 400 upward, the piston guide 80 is disengaged from the tubular portion 31, and the liquid discharge head 400 can be removed from the cap 200.

The piston guide 80 is supported by the case of the pump portion 75 via an urging member such as a coil spring.
When a pressing operation is performed on the liquid discharge head 400, the liquid discharge head 400 and the piston guide 80 are integrally lowered against the urging of the urging member. The pressing operation of the liquid discharge head 400 is stopped at a predetermined bottom dead center.
Further, 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 (positions shown in FIGS. 1 to 3) according to the bias of the urging member. ing.
The liquid discharge container 100 discharges a certain amount of bubbles by one pressing operation on the liquid discharge head 400 (an operation of pushing down the liquid discharge head 400 from the top dead center to the bottom dead center).

Further, by fixing the piston guide 80 and the liquid discharge head 400 to each other, a ring member 25 (the ring member 25 has a mesh holding ring 23 built therein) is arranged above the ball valve 90.
Therefore, the arrangement region of the ball valve 90 communicates with the internal space of the portion of the tubular portion 31 above the holding portion 32 via the internal space of the ring member 25 and the mesh holding ring 23, and thus the upper end of the tubular portion 31. It communicates with the primary discharge port 33.
When the pressing operation on the liquid discharge head 400 is performed, the bubbles generated by the former mechanism 19 are discharged upward from the primary discharge port 33 via the tubular portion 31.

The liquid filling container 800 is configured by filling the container body 10 of the liquid discharge container 100 with the liquid 101.
That is, the liquid filling container 800 according to the present embodiment includes the liquid discharge container 100 according to the present embodiment and the liquid 101 filled in the container body 10.

Further, the above-mentioned second member 50 is a nozzle member according to the present embodiment.
That is, the nozzle member according to the present embodiment has a primary discharge port 33 that discharges a liquid 101 that has become bubbles or a liquid 101 that remains in liquid form (in this embodiment, the liquid 101 that has become bubbles) in response to a pressing operation. A nozzle member (second member 50) that is detachably attached to the first member 30 to be used, and is opposite to the pressing direction by a pressing operation in a state where the nozzle member is attached to the first member 30. It is provided with a secondary discharge port 53 that opens in the direction and discharges the liquid 101 discharged from the primary discharge port 33 to the outside.

Next, the operation will be described.

In the normal state in which the liquid discharge head 400 is not pressed, the liquid discharge head 400 is located at the top dead center position.
In the pressing operation on the liquid discharge head 400, as shown in FIG. 1, the discharged body 22 such as a hand closes the opening 56a at the upper end (upper end of the pressing portion 56) of the liquid discharge head 400 (that is, the discharged body 22). Is opposed to the secondary discharge port 53), and the liquid discharge head 400 is pressed by the discharged body 22. That is, the pressing operation on the liquid discharge head 400 can be performed by one-handed operation.

When the pressing operation on the liquid discharge head 400 is performed, the liquid discharge head 400 and the piston guide 80 descend relative to the container body 10 against the urging of the urging member in the pump portion 75.
At this time, the liquid 101 and 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 section 20 pass through the mesh 24 to become finer and more uniform bubbles. The bubbles generated by the former mechanism 19 pass through the inside of the tubular portion 31 and are discharged from the primary discharge port 33 to the front chamber 21 and spread in the front chamber 21.
Further, the bubbles pass through the nozzle forming wall 55 formed on the facing portion 52 and are discharged from the secondary discharge port 53. The bubbles pass through the nozzle forming wall 55 and the secondary discharge port 53 to be shaped into a predetermined target shape (a shape imitating a flower in this embodiment), and are formed on the lower surface of the discharged body 22 that closes the opening 56a. Adhere to. That is, the bubbles ejected from the secondary discharge port 53 by the pressing operation of the pressing portion 56 are transferred to the discharged body 22, and the foam-shaped object, which is the bubbles shaped into a predetermined target shape, adheres to the lower surface of the discharged body 22. It will be in the state of.
After that, when the pressing operation on the liquid discharge head 400 is released, the piston guide 80 and the liquid discharge head 400 are raised according to the urging of the urging member, and the liquid discharge head 400 returns to the top dead center position.
After that, the ejected body 22 is lifted above the opening 56a and turned inside out, so that a foam-shaped object is formed on the ejected body 22. That is, it is possible to receive the foamed object having a predetermined target shape on the ejected body 22.
When the piston guide 80 rises, the liquid 101 in the container body 10 is sucked up into the pump portion 75 via the dip tube 77.

The pressing operation of the liquid discharge head 400 is 30 mm / s from the viewpoint of smoothly discharging bubbles from the secondary discharge port 53 and stably forming bubbles having a specific shape on the discharged body 22 such as a hand. The pressing pressure when pushing down the liquid discharge head 400 at a speed is preferably 1N or more, more preferably 5N or more, more preferably 40N or less, and further preferably 35N or less.

Further, the pressing portion 56 is formed with a hole 63 that allows the inner region and the outer region of the pressing portion 56 to communicate with each other. Therefore, even if the opening 56a is sealed by the ejected body 22 when the pressing operation on the liquid discharging head 400 is performed, the air inside the pressing portion 56 can be smoothly passed to the outside of the pressing portion 56 through the hole 63. Can be discharged.
Therefore, since the pressing operation of the liquid discharge head 400 can be performed with a lighter force, the liquid discharge head 400 can be smoothly pressed to discharge bubbles from the secondary discharge port 53. In addition, since the bubbles can be discharged smoothly, it is possible to preferably form bubbles having a specific shape into a desired three-dimensional shape.

After the bubbles spread in the front chamber 21 arranged in front of the secondary discharge port 53 and the front chamber 21 is filled with the bubbles, the bubbles can be discharged from the secondary discharge port 53. It becomes easy to sufficiently spread the bubbles over the entire area of the secondary discharge port 53, and it becomes easy to form bubbles in a predetermined target shape by the secondary discharge port 53. Further, since the facing portion 52 is arranged, the bubbles discharged from the primary discharge port 33 can easily spread in the front chamber 21.

The structure and operation of the cap 200 (including the pump unit 75) described here is an example, and the structure of the cap 200 includes other widely known structures as long as the gist of the present invention is not deviated. There is no problem even if the thing is applied to this embodiment.

There is.
Therefore, the bubbles discharged from the secondary discharge port 53 can be attached to the discharged body 22 by performing the pressing operation on the pressing portion 56 by the discharged body 22 such as a hand. Therefore, it is possible to receive the liquid 101 (foam in the present embodiment) on the ejected body 22 such as a hand by one-handed operation. That is, the bubbles can be received on the ejected body 22 by a simple operation.
Further, since the distance between the discharged body 22 and the secondary discharge port 53 can be kept constant by the pressing portion 56, the bubbles discharged from the secondary discharge port 53 are not crushed by the discharged body 22 and are covered. It can be received on the discharge body 22.
Therefore, in particular, when the bubbles are shaped into a predetermined target shape and discharged, it becomes easier to more accurately form the bubbles of the target shape on the ejected body 22.

It is more preferably more than twice, more preferably 10 times or less, and even more preferably 8 times or less.
Further, the height difference between the secondary discharge port 53 and the pressing portion 56 is preferably 5 mm or more and 20 mm or less, and more preferably 7 mm or more and 18 mm or less.
Further, the height dimension of the nozzle forming wall 55 is preferably 1 mm or more, and further preferably 2 mm or more, from the viewpoint of allowing bubbles to be satisfactorily received from the secondary discharge port 53 onto the ejected body 22. It is preferable, and it is preferably 10 mm or less, and more preferably 8 mm or less.
Further, when the pressing operation is performed on the pressing portion 56 without arranging the ejected body 22 at the position facing the secondary discharging port 53, the bubbles discharged from the secondary discharging port 53 are discharged from the pressing portion 56. It is preferable that the structure of the former mechanism 19 such as the pump portion 75, the height dimension of the pressing portion 56 and the nozzle forming wall 55, and the like are set so as to protrude above the tip (upper end).

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