The inner surface of the bottom portion 11b may be formed such that only the portion of the peripheral edge portion of the inner surface of the bottom portion 11b where the lower end opening portion 16a of the pipe 16 opens is located at the lowest position on the inner surface.

  For example, in addition to inclining the inner surface of the bottom 11b gradually downward from the second outer peripheral edge 11h toward the first outer peripheral edge 11g as in the above-described embodiment, the third outer peripheral edge 11i and the fourth outer peripheral edge 11j The cross-sectional shape along the direction opposite to each other is made concave, and the portion where the lower end opening 16a of the pipe 16 is open at the first outer peripheral edge 11g, that is, only the central portion in the length direction thereof, is the bottom 11b. It may be positioned at the lowest position on the inner surface.

  Here, the concave shape may be formed by a single curved surface, or gradually decreases downward from the third outer peripheral edge 11i toward the center of the third and fourth outer peripheral edges 11i, 11j facing each other. The inclined first inclined surface, the second inclined surface gradually inclined downward as the third and fourth outer peripheral edges 11i, 11j move from the fourth outer peripheral edge 11j toward the center of the opposite direction, and both of these inclinations You may comprise with the 3rd inclined surface which connected the lower ends of the surface and inclined gradually downward toward the 1st outer periphery 11g from the 2nd outer periphery 11h.

In the above-described embodiment, a rectangular shape is shown as a top view shape of the bottom portion 11b. Alternatively, for example, a circular shape, a triangular shape, or a polygonal shape having five or more corners may be used.
Furthermore, in the said embodiment, although the pipe 16 was curved, instead of this, you may extend along the said center axis line O direction, for example, without making it curve over the full length. The inner surface of the bottom portion 11b is gradually inclined downward from the first to fourth outer peripheral edges 11g, 11h, 11i, and 11j toward the central portion in the radial direction of the inner surface. You may make it the reverse quadrangular pyramid shape comprised by the four inclined surfaces which shortened the length. Alternatively, the inner surface of the bottom portion 11b may be formed in a concave curved surface shape such that the central portion in the radial direction is located at the lowest position.

  When the remaining liquid is used, the time required for immersing the lower end opening of the pipe in the liquid can be shortened.
