This is a foot-operated discharge container that is used to spray and apply a coating liquid such as a cooling agent, a bactericide, or a fragrance to the back of the foot from a nozzle opening 14 that opens on the upper surface of the foot. This aerosol container 10
The container body 12 includes a multi-hole discharge nozzle member 11 protruding above the container body 12.

A stem 13 is provided at the distal end of the container body 12 in which the coating liquid (content liquid) is hermetically stored.
It protrudes in a state of being urged upward by the elasticity of a spring provided inside a valve mounted inside 2. A disk-shaped multi-hole discharge nozzle member 11 is attached so as to cover the tip of the stem 13.
Is pressed downward in the axial direction of the stem 13, whereby the application liquid is discharged upward from the nozzle opening 14 communicating with the inside of the container body 12 via the stem 13, and is applied to the back of the foot.

The container body 12 is a hollow container having a circular cross section made of synthetic resin, metal or the like, and has a bottom surface having a diameter of about 9 mm.
cm, a height of about 8 cm, a low center of gravity due to its shape, and a stable state in which the multi-hole discharge nozzle member 11 of the aerosol container 10 does not fall down even when pressed with feet. It is placed on the floor.

The multi-hole discharge nozzle member 11 is made of synthetic resin and has a disk shape. At the center of the lower surface of the multi-hole discharge nozzle member 11, a cylindrical stem fitting projection 15 projects downward, and a fitting hole 16 of the stem fitting projection 15 is formed.
By fitting the upper end portion of the stem 13 into the stem 13, the stem 13 communicates with the application liquid passage 20 formed inside the multi-hole discharge nozzle member 11 through the central through hole 81 of the stem fitting projection 15. The coating liquid passage 20 is formed in a lateral flow passage 2 extending radially from the center of the multi-hole discharge nozzle member 11.
0a and six vertical flow passages 20b which penetrate the nozzle upper body 17 and are formed at six places at the center and the periphery thereof. Each of the vertical flow passages 20b is a multi-hole discharge nozzle member 11
Are connected to the nozzle openings 15 provided at six places at the center of the surface and at the peripheral portion thereof.

The multi-hole discharge nozzle member 11 has a lateral flow passage 20a extending in the radial direction.
As shown in FIG. 3, the nozzle upper body 17 and the nozzle lower body 18 are integrated with an O-ring 26 interposed therebetween in order to form them inside 1. That is, three straight grooves extending in the diameter direction of the flat central circular protrusion 21 on the upper surface of the nozzle lower body 18 are formed so as to intersect at the center point, and thus are formed in six radial directions. Is provided with a radiation groove 22. Therefore, if the nozzle lower body 18 is attached and fixed to the engagement recess 23 formed on the lower surface side of the nozzle upper body 17 while keeping the upper surface of the central circular projection 21 in close contact with the lower surface of the nozzle upper body 17, the radiation groove 22 A lateral flow passage 20a is formed by being defined by the lower surface of the nozzle upper body 17, and each radiation groove 22 has a tip formed at a peripheral portion of the nozzle upper body 17, as shown in FIG. It communicates with each of the six vertical flow passages 20b.

According to this embodiment, the nozzle lower body 18 is mounted and fixed in an airtight manner with the O-ring 26 interposed in the engagement concave portion 23 formed on the lower surface side of the nozzle upper body 17 to provide a lateral flow passage. A seal structure 24 is employed to enable a smooth supply of the coating liquid to each nozzle opening 14 via the nozzle 20a.

As shown in FIG. 2, the seal structure 24 includes an O-ring 26 in the engagement recess 23 of the nozzle upper body 17.
The contact surface of the groove is a concave annular inclined surface 27 that is tapered toward the outside, and the contact surface of the O-ring 26 in the nozzle lower body 18 is tapered inward toward the concave. The lower body annular inclined surface 28 is arranged to face the inclined surface 27, and the O-ring 26 is sandwiched between the concave annular inclined surface 27 and the lower annular inclined surface 28 while being compressed.

The O-ring 26 is made of, for example, silicon, NBR
(Nitrile butadiene rubber) is an annular member having a circular cross section and having a size that can be arranged along the concave annular inclined surface 27 or the lower body annular inclined surface 28.

The annular recessed inclined surface 27 is provided with the nozzle upper body 17.
The lower surface of the nozzle upper body 17 is formed as an outer inclined surface of a lower surface annular projection 30 provided along the inner side of the skirt wall 29 at a distance from the skirt wall 29 forming the engagement recess 23 on the lower surface side of the nozzle. Is formed at an angle of 45 ° with respect to. Note that a circular concave portion in which the central circular protrusion 21 of the nozzle lower body 18 is disposed in close contact with the lower surface annular protrusion 30 is formed.

The lower body annular inclined surface 28 is provided for the nozzle lower body 1.
8 on the upper surface of the nozzle lower body 18 as an inner inclined surface of an upper surface annular projection 31 provided along the periphery of the nozzle lower body 18 at a distance from the central circular projection 23. It is formed to be inclined at an angle of 45 °.

The seal structure 24 is formed by fitting the lower nozzle body 18 into the engaging recess 23 of the upper nozzle body 17 with the O-ring 26 interposed therebetween, thereby forming the multi-hole discharge nozzle member 11 integrated with the nozzle body. It is provided when forming.

Here, the skirt wall 2 of the nozzle lower body 18
At the inner wall surface of the nozzle 9, a predetermined distance from the lower surface of the nozzle upper body 17 (the nozzle lower body 18 is attached to the engagement recess 23 with the central circular projection 21 being in close contact with the circular recess of the nozzle upper body 17). At intervals, a locking projection 25 that locks the peripheral edge of the lower surface of the nozzle lower body 18 is disposed, for example, at four locations in the circumferential direction. Therefore, while the O-ring 26 is interposed between the concave annular inclined surface 27 and the lower body annular inclined surface 28, the nozzle lower body 18 is fitted into the engaging concave portion 23, and the lower peripheral edge of the nozzle lower body 18 is fitted to the locking projection 25. If locked, nozzle lower body 1
8 is mounted and fixed to the nozzle upper body 17, and the multi-hole discharge nozzle member 11 that is firmly integrated is obtained.

The diameter of the circular cross section of the O-ring 26 is
The O-ring 26 is compressed when the nozzle lower body 18 is mounted and fixed on the nozzle upper body 17 because the distance between the concave annular slope 27 and the lower annular slope 28 is opposite. By being sandwiched between them, it tightly adheres and effectively exerts sealing properties.

According to the seal structure 24, the O-ring 2
6 is sandwiched between the recessed annular inclined surface 27 as the inclined surface and the lower annular inclined surface 28, so that a compressive force is applied not only in the mounting direction but also in the horizontal direction. Accordingly, even if the locking of the nozzle lower body 18 in the mounting direction by the locking projections 25 is loosened and play occurs, and a sufficient compressive force cannot be applied in the vertical direction, the skirt surrounding the nozzle lower body 18 can be used. Since it is supported by the wall 29 and the compressive force in the lateral direction is maintained, it is possible to maintain a strong sealing property.

That is, according to the present embodiment, the provision of the seal structure 24 ensures that the sealing performance when the nozzle lower body 18 is mounted and fixed to the engagement recess 23 via the O-ring 26 is reliably maintained. can do. Therefore, according to the aerosol container 10 of the present embodiment, it is possible to provide the multi-hole discharge nozzle member 11 in which the sealing performance is reliably maintained and the nozzle upper body 17 and the nozzle lower body 18 are integrated.

According to the present embodiment, the multi-hole discharge nozzle member 11 has an upper surface diameter of about 5 cm and a height of about 1.5 cm.
cm. As shown in FIG. 3, on the upper surface of the multi-hole discharge nozzle member 11, nozzle openings 14 having a diameter of 0.3 mm are provided at one place at the center and six places along the circumferential direction, that is, a total of seven places. Open. Since the seven nozzle openings 14 are substantially uniformly dispersed on the upper surface of the multi-hole discharge nozzle member 11, the application liquid as the internal solution is sprayed substantially uniformly over the entire upper surface of the multi-hole discharge nozzle member 11 ( Injection).

At the periphery of the upper surface of the multi-hole discharge nozzle member 11, an annular wall 32, which is an annular projection, is formed to protrude at a height of about 5 mm so as to integrally surround the seven injection ports 13. .

The multi-hole discharge nozzle member 11 of the aerosol container 10 placed under the desk is stepped on with the foot while covering the annular wall 32 from above with the portion of the back of the foot where the content liquid is to be applied. When pressed, the content liquid is sprayed from the nozzle opening 14 and applied to the back of the foot. Here, the annular wall 32 is arranged with a diameter of about 4 cm along the peripheral edge of the upper surface of the multi-hole discharge nozzle member 11, and its installation area is large enough to be sufficiently covered by the back surface of the foot. Inside the annular wall 32 is sealed and the nozzle opening 14
This makes it difficult to leak the jet noise from the loudspeaker and exerts a noise reduction effect.
Also, the height of the annular wall 32, which is a projection that integrally surrounds the multiple nozzle openings 14, integrally determines the bottom surface of the foot and the nozzle openings 14.
, That is, the spray distance is secured.

The sound pressure level of the aerosol container 10 of the present embodiment in which the annular wall 32 is disposed as a sound deadening wall and the sound pressure level of the aerosol container without the sound deadening wall at the time of spraying are compared and measured with the same propellant pressure. In the case of an aerosol container without a sound deadening wall, it is 68 dB (sound inside a train), whereas the aerosol container 10 with a sound deadening wall is 57 dB.
(The sound of ordinary conversation at a distance of 1 m), and a clear noise reduction effect was recognized. In addition, this measurement was performed in the environment of the surrounding sound of 50 db at a distance of 0.1 m from the nozzle using a sound level meter NA-09 (manufactured by Rion Co., Ltd.).

Further, according to this embodiment, one end of the multi-hole discharge nozzle member 11 is joined and locked to the outer peripheral portion of the stem fitting projection 15 as shown in FIGS. 4 (a) and 4 (b). Then, a pair of synthetic resin leaf springs 51 are attached as rotation urging means so as to extend in opposite directions. In addition,
The other end of the leaf spring 51 is connected to a circular wall 6 of a hakama member 60 described later.
It is locked so as to be sandwiched between the cuts 62 formed in the first.

Further, according to the present embodiment, the multi-hole discharge nozzle member 11 is attached to the lower end surface of the annular skirt wall 29 provided along the peripheral edge of the lower surface, and is provided with four A stopper projection (projection) 53 having a width of about 3 mm is provided at the four divided locations so as to protrude downward.
The stopper projections 53 are inserted and arranged in two-step cutout grooves 64 formed at four places in a circular groove 63 of a skirt member 60 described later.

Then, the aerosol container 10 of the present embodiment
According to this, the hakama member 60 for providing the circular wall 61 and the circular groove 63 outside the circular wall 61 concentrically with the stem 13 so as to cover the outer peripheral surface of the upper end portion of the container body 12,
It is fitted and mounted on the peripheral surface of the container body 12 around the stem 13.

As shown in FIGS. 2, 5 (a), and 5 (b), the skirt member 60 is provided with the insertion opening 3 of the stem 13 at the center.
5 is an annular member having a circular planar shape and an equilateral trapezoidal cross-sectional shape. Then, the lower end surface 37 cut diagonally inside the lower half skirt portion 36 that spreads out is placed on an obliquely curved shoulder portion 38 on the peripheral surface of the upper end portion of the container body 12 so that the stem 13 is inserted. The skirt member 60 is mounted concentrically with the stem 13 while being arranged at the center of the opening 35.

A circular wall 61 is erected on the upper half of the skirt member 60 along the outside of the insertion opening 35.
The outer peripheral wall 41 is provided upright at a distance from the circular wall 61 so that a circular groove 63 is formed. A pair of cuts 62 are formed in the circular wall 61 at positions opposing each other in the diametrical direction. When the multi-hole discharge nozzle member 11 is attached to the stem 13, the other end of the leaf spring 51 is inserted into the cut 62. It is inserted and locked so as to be sandwiched. The circular groove 63 is provided with four two-step notched grooves 64 formed as positions for dividing the circular groove into four parts in the circumferential direction as rotation restricting portions, and the multi-hole discharge nozzle member 11 is attached to the stem 13. At this time, the stopper projections 53 are inserted and arranged in the two-step notched grooves 64, respectively.

The two-step notch groove 64 is formed to have a length of about 10 mm longer than the width of the stopper protrusion 53, so that the stopper protrusion 53 slides in the circumferential direction inside the two-step notch groove 64. The multi-hole discharge nozzle member 11 can be rotated in the circumferential direction, with the range in which the slide movement is possible as a predetermined play angle range. In addition, the side surface of the stopper projection 53 abuts the side surface of the two-step notch groove 64 as an anti-rotation wall, so that sliding in the circumferential direction is limited, and thereby the play angle range in which the multi-hole discharge nozzle member 11 can rotate is limited. Will be limited.

The two-step notch groove 64 has a shallow upper portion 39 occupying approximately one third of the center in the circumferential direction,
This is a two-stage structure divided into a lower part 40 on both sides of the upper part 39. When the stopper projection 53 is located above the upper section 39, even if the multi-hole ejection nozzle member 11 is pressed, the tip surface of the stopper projection 53 immediately contacts the upper section 39 until the application liquid is ejected. The multi-hole discharge nozzle member 11 cannot be pushed down, and discharge becomes impossible. On the other hand, when the stopper projection 53 is located above the lower portion 40,
When the multi-hole ejection nozzle member 11 is pressed, it is possible to smoothly push down the stopper projection 53 until the front end surface of the stopper projection 53 comes into contact with the bottom surface of the lower step portion 40, so that the application liquid can be easily ejected. That is, the upper step portion 39 in the two-step notch groove 64 as the rotation restricting portion is brought into contact with the tip of the stopper projection 53 so that the multi-hole discharge nozzle member
The lower part 40 constitutes a pressing release part, which constitutes a pressing restricting part that regulates the pressing of the first part.

When the other end of each leaf spring 51 is engaged with the notch 62 of the skirt member 60, the stopper projection 53 and the leaf spring 51 are moved to the two-step cutout groove 6 respectively.
4 is provided on the multi-hole discharge nozzle member 11 in a positional relationship such that it is disposed above the upper step portion 39. Therefore, in order to arrange each stopper projection 53 above the lower step portion 40, it is necessary to rotate the multi-hole discharge nozzle member 11 against the urging force of the leaf spring 51.

A cap mounting pedestal 42 is provided outside the outer peripheral wall 41 of the hakama member 60.
The lower end surface of the cap 43 is abutted against the pedestal 42 while the cap 43 is fitted to the outside of the housing, and the cap 43 is detachably mounted so as to cover the multi-hole discharge nozzle member 11 (see FIGS. 1 and 2).

According to the aerosol container 10 of this embodiment, the skirt member 60 is provided so as to cover the outer peripheral surface of the upper end portion of the container body 12, and then the upper end of the stem 13 is fitted into the fitting hole 16 of the stem fitting projection 15. The multi-hole discharge nozzle member 11 is attached so as to cover the tip of the stem 13 while fitting the parts, and the container body 12, the skirt member 60, and the multi-hole discharge nozzle member 11 are integrated. In this state, the other end of each leaf spring 51 is inserted and locked in the notch 62 of the skirt member 60, and each stopper projection 53 is formed in the upper step 3 of the two-step notch groove 64.
9 above. Therefore, even if the multi-hole discharge nozzle member 11 is pressed, the multi-hole discharge nozzle member 11 is not sufficiently pushed down, and the application liquid is not discharged from the nozzle opening 14.

In order to apply the coating solution to the back surface of the foot and perform the care of the foot by the aerosol container 10 of the present embodiment, the foot is placed on the upper surface of the multi-hole discharge nozzle member 11 and the foot is placed on one of the right and left sides. If twisted, the side surface of the stopper projection 53 becomes 2
The multi-hole discharge nozzle member 11 rotates against the urging force of the leaf spring 51 until it comes into contact with the side surface of the step cut groove 64, and the stopper projection 53 moves above the lower step 40 of the two step cut groove 64. . If the multi-hole discharge nozzle member 11 is pressed down from this state to press the multi-hole discharge nozzle member 11, the multi-hole discharge nozzle member 1
1 is sufficiently pushed down, and the application liquid is applied directly from the spray nozzle 19 to the back of the foot via the nozzle opening 14.

After the application liquid is applied, the foot placed on the multi-hole discharge nozzle member 11 is released to release the pressure, and the stem 1
The multi-hole discharge nozzle member 11 is pushed up by the elasticity of a spring provided in the valve for projecting the multi-hole discharge nozzle member 3, and the multi-hole discharge nozzle member 1 is pressed by the urging force of the leaf spring 51.
1 rotates in the opposite direction, and automatically restores the state in which the stopper projection 53 is located above the upper step portion 39 of the two-step notch groove 64 and the pressing down is restricted before the foot is placed.
Therefore, in order to discharge the application liquid from the spray nozzle 19, it is necessary to rotate the multi-hole discharge nozzle member 11 again.

That is, the aerosol container 1 of the present embodiment
According to 0, when the pressing of the multi-hole discharge nozzle member 11 is released, the locked state in which the multi-hole discharge nozzle member 11 cannot be pressed is automatically restored to easily prevent malfunction. Will be possible.

The aerosol container 10 of the present embodiment is
According to the method, when the multi-hole discharge nozzle member 11 of the aerosol container 10 placed under the desk or the like is pressed so as to be pressed on the sole of the foot, the coating liquid is ejected from the nozzle opening 14 toward the sole of the foot. The discharged application liquid is applied directly and quickly to the sole of the foot. Here, the multi-hole discharge nozzle member 11 is provided with an annular wall 32 as a protrusion at the peripheral edge of the upper surface, and the gap between the back surface of the foot when stepping on and the nozzle opening 14 is maintained. Is smooth and smooth, and the multi-hole discharge nozzle member 11 is provided with a large number (seven in this embodiment) of nozzle openings 14, so that the sprayed application liquid can be pressed by a single stepping operation. It can be easily applied to the sole of the foot over a wide area.

The present invention can be variously modified without being limited to the above embodiment. For example, the discharge nozzle member does not necessarily need to be a multi-hole discharge nozzle member, and may be a discharge nozzle member having a single nozzle opening. The projection that maintains the distance between the back surface of the foot and the nozzle opening when stepped on does not necessarily need to be an annular wall,
Numerous rod-shaped projections (for example, 3 mm or more, preferably 5 m
m or more). The injection angle of each nozzle opening can be set, for example, in a range of 45 ° left and right. Examples of the content liquid include germicides, antiperspirants, antifungal agents, anti-inflammatory agents, drugs such as ethanol, and fragrances.

As a means for installing the aerosol container on a floor or the like in a stable state so that the aerosol container does not fall down even when stepping on the foot, for example, the diameter of the bottom surface of the container body is set to 50 mm or more and the diameter is set to 2 / 3 or more, preferably at least 1.0 times the height, the container body is provided with a center of gravity and a bottom area such that the falling angle of the aerosol container becomes 30 degrees or more when the container body is emptied. A method of designing, a method of providing a fixing means by a non-slip such as a locking screw or an adhesive or a rubber provided on the container bottom for fixing the container body to the stepping position, or a fixing table for storing the aerosol container in the stepping position in advance Or the like, and an aerosol container can be exchangeably fitted to this fixing base or the like.

Further, according to the present invention, as shown in FIG. 6, the annular wall 32 of the multi-hole discharge nozzle member 11 has a double-structured wall composed of an outer circumferential wall 66 and an inner corrugated wall 67. The outer convex portion of the inner corrugated wall 67 is joined to the inner surface of the outer circumferential wall 66, and a substantially triangular cross section is formed between the outer concave portion of the inner corrugated wall 67 and the inner surface of the outer circumferential wall 66. The gap 70 may be formed at each peak of the wave. According to the annular wall 32, a double structure including the outer circumferential wall 66 and the inner corrugated wall 67 is provided, and the gap 70 is formed between them, so that the noise reduction effect is enhanced. Further, if the annular wall 32 is formed using a foamed resin molding material, the effect of suppressing the injection noise can be further increased. A foaming material such as foamed polyethylene may be attached to the inner surface of the inner corrugated wall 67 to increase the noise reduction effect. Further, the sound deadening effect can be enhanced by forming the inner surface of the annular wall 32 into, for example, a tooth shape. Note that the muffling means does not necessarily need to be formed by an annular wall.

The upper surface of the multi-hole discharge nozzle member 11 is located between the circumferential nozzle openings 14 by 5 mm.
If the protrusions 80 of approximately the same height are provided in six places, the protrusions 80 at the six places bite into the acupoints on the back surface of the foot when the multi-hole discharge nozzle member 11 is stepped on and pressed, and stimulated. In addition to exerting the acupressure effect, it also fulfills the function of ensuring the spray distance of the application liquid.

The annular wall disposed along the peripheral edge of the upper surface of the discharge nozzle member may be, for example, a circular wall provided alone or double along the peripheral edge of the upper surface of the discharge nozzle member. . Further, the outer circumferential wall and the inner corrugated wall are partially separated from each other without being joined to each other, and an annular wall or a substantially triangular cross section between the outer circumferential wall and the inner corrugated wall is filled in to form the outer circumferential wall and the inner corrugated wall. An integral annular wall can also be employed. Further, a roof member having a notch along the shape of the foot, for example, may be joined to the upper end of the annular wall to form an opening large enough to cover the notch on the back surface of the foot. Furthermore, the inner wall of the annular wall 32 may be slid on the upper surface of the multi-hole discharge nozzle member 11 in a state where the inner wall is inclined inward (see FIG. 7), so that the inner side of the annular wall 32 may have a bowl shape.

On the other hand, as the rotation urging means for urging the stopper projection 53 of the multi-hole discharge nozzle member 11 so as to be arranged in the upper step 39 of the two-step notch groove 64, the plate spring 51 of the above embodiment is used. Alternatively, for example, as shown in FIG. 7, a coil spring 71 can be used. That is, the coil portion 72 of the coil spring 71 is mounted on the stem fitting projection 15 of the multi-hole discharge nozzle member 11, and
One of the linear ends 73 is locked so as to be sandwiched between a pair of locking projections 74 provided on the lower surface of the nozzle member 11, and the other linear end 75 is fixed to the circular wall 6 of the skirt member 60.
It is locked so as to be sandwiched by the notch 62 formed in the first.

The rotation urging means shown in FIG. 7 also rotates the multi-hole discharge nozzle member 11 rotated at the time of application in the opposite direction by the urging force of the coil spring 71, and the stopper projection 53 before the foot is placed. The multi-hole discharge nozzle member 11 can be automatically restored to a state in which the depression is restricted above the upper step 39 of the two-step notch groove 64 and the depression is restricted.

It is not necessary that the concave annular inclined surface 27 and the lower annular annular surface 28 sandwiching the O-ring 26 be inclined at an angle of 45 ° with respect to a reference surface such as the upper surface of the nozzle lower body. However, it is preferable to incline at an angle of 25 to 65 °, and it is particularly preferable to incline at an angle of 35 to 55 °. When the inclination angle is in the range of 25 to 65 °, a reliable sealing property can be ensured even with a multi-hole discharge nozzle member that does not have strict dimensional accuracy, and parts can be manufactured at low cost.

Further, it is also possible to make the concave annular inclined surface taper inward toward the inside and to make the lower annular annular inclined surface outward. Further, it is not always necessary to make the inclination angles coincide with each other so as to be opposed in parallel.

According to the aerosol container of the present invention, the multi-hole discharge nozzle member does not necessarily have to be a disk, but may be a polygon such as a triangle or a quadrangle.

According to the aerosol container and the method of using the aerosol container of the present invention, the contents are directly discharged and applied to the soles of the feet by the pressing force of the foot, so that it is necessary to bend down and sit down. Without having to do so, the contents such as drugs can be easily applied to the back of the foot or between the fingers.

Further, it is recognized that the aerosol container of the present invention does not bother and use the jetting sound when the content liquid is applied if the discharge nozzle member is provided with a muffling means. It can be easily reduced to the extent that it is not performed.

Further, in the aerosol container according to the present invention, a skirt member is fitted to a peripheral surface of the container body surrounding a stem of the container body to which the discharge nozzle member is attached, and the discharge nozzle member is connected to the skirt member. When the nozzle member is released from the pressure, the nozzle member is automatically restored to the locked state when the nozzle member is released, and malfunctions. Can be easily prevented.

Further, the aerosol container of the present invention comprises:
The discharge nozzle member is fitted in the nozzle lower body with an O-ring interposed on the inner surface of the engagement concave portion formed on the lower surface side of the nozzle upper body, so that the nozzle lower body is sealed in the nozzle upper body. A sealing structure formed by mounting and fixing the nozzle upper body and the nozzle lower body in a hermetically sealed state, a recess in which the contact surface of the O-ring in the engagement recess is tapered inward or outward. An annular inclined surface, and a contact surface of an O-ring in the nozzle lower body inclined inward or outward in a tapered shape to form a lower body annular inclined surface opposed to the concave annular inclined surface; If the O-ring is compressed and sandwiched between the annular inclined surface and the lower annular inclined surface, the sealing performance is reliably maintained, and the nozzle upper body and the nozzle lower body are integrated with each other. It may comprise a nozzle member.
