The auxiliary pouring tube 23 is held between the 2'lb.

Further, on the outer edge of the upper end opening /2 of the gutter groove /j, there is a hole 27 into which a locking protrusion protruding from the upper end of the lid 2j, which will be described later, is inserted.
is formed on the inner surface of the groove at the lower end opening 0.20 of the gutter groove /j, and the above-mentioned lid, 2J - the claw piece 2g protruding from the lower end.
A protrusion λ for locking is formed.

The auxiliary pouring pipe 23 is composed of an abbreviated tube body 23a and a trumpet-shaped seal tube 2311 made of an elastic material such as rubber and connected to the upper end of the tube body 23eL.

By abutting the auxiliary pouring pipe 23, the seal pipe, 23b against the upper end of the gutter groove/j and the periphery of the opening, and pressing the pipe body 23g against the bottom surface of the horizontal groove ljb of the gutter/gutter,
It is removably arranged in the gutter groove /j. At the same time, the tube body, 2
3g is the arm portion of the holder 24t, 211-b, 24L
It is held by blfC to prevent swinging in the left-right, front-back, and front-back directions.

Therefore, the spout /2 of the liquid spout pipe // is exposed to the upper end opening 32 of the spout auxiliary pipe 3 through the annular gap.

Further, the lower end opening 33 of the pouring auxiliary pipe 23 is located slightly lower than the lower end opening 0.20 of the gutter N/J.

Furthermore, the M2.3- is formed in an abbreviated shape to be the same as the shape of the front opening of the gutter groove /j, and has an upward protrusion 2 at its upper end, and an upwardly directed projection 2 at its lower end. An inward facing claw piece 2g is formed, and the side wall 3 of the gutter groove /j is formed on the inner surface of the claw piece 2g.
0.30 protrusions 3/ and 3/ are formed which press-fit into the inner surface.
