The taper-shaped tubular portion 13 is elastically deformable, and an exhaust valve 16 is formed by the lower end of the lower taper-shaped tubular portion 13 and the inner wall surface of the body portion.

[0006]

[Action]

 As shown in FIG. 2, the sliding bottom plate 10 is fitted by inclining the container body 1 in advance and filling the inside of the body with the cream-like material 6 from the lower end opening of the body. Also, turn it upside down and push it into the lower part of the body 2 from the lower end of the body. During the pushing, the air between the horizontal plate 14 of the sliding bottom plate 10 and the lower surface 6a (the upper surface in FIG. 2) of the cream-like object 6 passes through the air discharge hole 15 as it is pushed, and then slides. Exhaust formed by passing between the middle tubular portion 11 of the bottom plate and the inner wall surface of the container body 2 and further by elastically pressure contacting the lower taper tubular portion 13 of the sliding bottom plate 10 to the inner wall surface of the body portion. Exhausted through valve 16. When the pushing of the sliding bottom plate 10 is changed due to the completion of the air discharge, and the pushing becomes difficult, the cream-like material is discharged through the air discharge valve if the pushing is stopped at this time. Never.
