  2. Description of the Related Art Conventionally, a filling valve in which a container is filled with a liquid such as a beverage, and a filling valve with a screen attached to a filling nozzle at the tip is known. (Patent Documents 1 and 2)

Japanese Utility Model Publication No. 04-007498 (FIG. 1) JP 2006-151473 A (FIG. 5)

According to Patent Document 1, the filling valve has a screen holding ring fitted to the outer periphery of the lower end portion of the main liquid nozzle, a bridge is fixed to the lower inner side of the screen holding ring, and an opening is formed at the center of the bridge. The screen is fixed so as to cover the opening.
However, in the technique of Patent Document 1, since the screen is fixed to the bridge, it is not assumed that the screen is replaced. Instead, the screen is replaced while the screen is fixed to the bridge. There is a risk of becoming expensive.

According to Patent Document 2, the filling valve is provided with a liquid outlet member in which a valve seat of the liquid valve is formed and a screen is attached at the lower end of the filling valve housing.
However, in the technique of Patent Document 2, when liquid is present in the filling valve, if the liquid outlet member to which the screen is attached is to be removed, the liquid in the filling valve goes out. The liquid outlet member to which the screen is attached cannot be removed. Accordingly, there is a possibility that the screen, that is, the liquid outlet member to which the screen is attached cannot be replaced in the state where the liquid exists in the filling valve.

  In the present invention, a screen is arranged between the liquid passage of the filling valve body and the filling nozzle, and the filling nozzle is attached to and detached from the filling valve body via a U-shaped spring. By disengaging from the main body of the filling valve, a filling valve having a structure in which the screen can be easily taken out and replaced even when liquid is present in the filling valve, and the U-shaped spring does not fall during filling. The purpose is to do.

The present invention solves the above problems by the following means.
(1) The filling valve of the first means is a filling valve that fills a container with a beverage or the like provided with a screen at the tip of the liquid passage, and a liquid passage below the liquid passage opening and closing portion in the liquid passage of the filling valve body; A first U-shape made of a stainless steel wire for springs and the like, which is arranged between the liquid passages of the filling nozzle at the tip, engages with the filling nozzle, and engages with the filling valve body. The filling nozzle is attached to and detached from the filling valve body by a spring, and the filling valve of the second means is the filling valve of the first means, and the first U-shaped spring is the filling nozzle during filling. It is characterized by having a configuration surrounded by a centering bell arranged on the outer periphery of the.
(2) The filling valve of the second means is an easily attachable / detachable engagement with the outer peripheral portion of the centering bell and the centering bell mounting member of the filling valve in the filling valve of the first means. The centering bell is configured to be attached to and detached from the centering bell mounting member by a second U-shaped spring made of a stainless steel wire for a spring or the like.

(3) The filling valve of the third means is the filling valve of the second means, wherein after the second U-shaped spring is detached and the centering bell is detached from the centering bell attaching member, The filling nozzle is separated from the filling valve main body by detaching the U-shaped spring.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIGS.
FIG. 10 is a front sectional view showing a partial view of the filling valve according to the second embodiment of the present invention, and corresponds to FIG.
11 is a cross-sectional view taken along line EE in FIG.
FIG. 12 is a view for explaining a state where the filling nozzle is released from the engagement with the U-shaped spring by rotating the filling nozzle by a predetermined angle and is in line contact.
10 to 12, the same structure as that of the first embodiment is denoted by the same symbol, and redundant description is omitted.

The filling valve 2 serves as a so-called two-sided groove 41g, arc portion 41r, and a boundary between the groove 41g and the arc portion 41r. The filling nozzle 41 that is formed of a corner 41e and that engages with the tool 30 forms a so-called two-sided groove 41k having a parallel surface, and that forms a chamfer 41c at the corner of the head. Have.
The filling nozzle 41 has a receiving surface 41 h that receives the screen 10.
FIG. 10 shows that the tool 30 is picked up, and the engaging portion 31a and the engaging portion 32a of the sandwiching tool 31 and the sandwiching tool 32 are respectively engaged with the two grooves 41k of the filling nozzle 41. 30 shows a state in which the filling nozzle 41 is detached from the filling valve 2 by rotating 30 in the direction of arrow R by a predetermined angle (90 ° in this case) and then pulling it out in the direction of arrow S.

Next, the operation of the filling valve 2 according to the second embodiment will be described.
The tool 30 is picked up and pinched so that the engaging portion 31a and the engaging portion 32a of the pinching tool 31 and the pinching tool 32 are engaged with the two grooves 41k of the filling nozzle 41, respectively. The first U-shaped spring 12 changes from engaging with the groove 41g to engaging with the arc portion 41r through the corner portion 41e. That is, the first U-shaped spring 12 changes from the state shown by the two-dot chain line shown in FIG. 12 to the state shown by the solid line.
When the first U-shaped spring 12 is in the state indicated by the solid line in FIG. 12, the filling nozzle 41 changes from the state in which the engagement with the first U-shaped spring 12 is fitted into the groove 41g to the line contact state with the arc portion 41r. When the tool 30 is pulled out in the direction of arrow S with the engaging portion 31a and the engaging portion 32a of the pinching tool 31 and the pinching tool 32 engaged with the groove 41k, respectively, the tool 30 can be detached from the lower portion 16 of the filling valve body. it can.
The first U-shaped spring 12 remains in the groove 16g of the lower portion 16 of the filling valve body.

  When the filling nozzle 41 having received the screen 10 on the receiving surface 41h is re-engaged with the first U-shaped spring 12 remaining in the groove 16g of the filling valve body lower portion 16, that is, the filling nozzle 41 is moved to the lower portion 16 of the filling valve body. In the case where the tool 30 is mounted, the tool 30 is inserted into the groove 41k, and the engaging portion 31a and the engaging portion 31a of the sandwiching tool 32 are engaged in the groove 41k. When the portion 32a is engaged and the filling nozzle 41 is sandwiched by the tool 30 and pushed downward from the filling valve 2 upward toward the first U-shaped spring 12 remaining in the groove 16g, The chamfered portion 41c of the filling nozzle 41 starts to engage with the inner peripheral side of the first U-shaped spring 12, and further pushes the filling nozzle 41 upward from below in the direction opposite to the arrow S direction. Then, the first U-shaped spring 12 operates against the spring force of the first U-shaped spring 12, and the tool 30 with the filling nozzle 41 interposed therebetween is rotated to an appropriate angle, thereby filling. The first U-shaped spring 12 can be engaged with the groove 41g of the nozzle 41, and the filling nozzle 41 is attached to the lower portion 16 of the filling valve body.

  As described above, in the filling valve 2 of the second embodiment, the filling nozzle 41 is pulled out from the filling valve main body lower part 16 by using the tool 30 without pulling out the centering bell 17 and removed, or Therefore, the screen 10 can be replaced and cleaned very easily.
