It is fitted into the concave groove. The cylindrical portion 6 has a large inner diameter portion 9 at the upper portion thereof, and an outside air suction window hole 10 is formed at the lower end thereof. In the illustrated example, a portion immediately below the large inner diameter portion is a medium diameter portion 11, a lower portion thereof is a small diameter portion 12, and a lower portion thereof is a second small diameter portion 13 having a smaller diameter. A hole 14 is provided. A suction pipe 15 is vertically provided from the inside of the lower end of the tubular portion 6, and a groove-shaped flow path forming member 16 is fitted to the lower end thereof. The member is such that a short cylinder 17 having a ridge on the inner surface of the lower end is fitted to the outer surface of the lower end of the suction pipe by contacting the lower end of the suction pipe 15 with the upper surface of the ridge, and with the lower outer peripheral surface of the short cylinder. A plurality of plate pieces 18 are protruded by vertically and downwardly projecting laterally outwardly with both portions of the lower end surface as a connecting portion, and a groove-like flow path 19 is formed between these plate pieces. There is. The groove-shaped channel may be formed directly at the lower end of the suction pipe, or the tubular portion 6
The suction pipe 15 and the suction pipe 15 may be integrally formed. A bag 21 is stored in the container body 1 and a creamy substance is put in the bag.
20 is filled, and then the suction pipe 15 and the lower half of the tubular portion 6 are inserted into the bag, and the bag mouth edge portion is brought into close contact with the outer surface of the tubular portion between the air vent hole 14 and the window hole 10. By doing so, the bag mouth portion 22 is sealed. The bag is made of a synthetic resin sheet, but if the stored items are easily oxidized, it is made of a sheet excellent in gas barrier property. The filling of the creamy substance in the bag is
It may be carried out by injection from the lower end of the suction pipe 15, and the air vent hole 14 is for exhausting the air in the bag.

Reference numeral 25 denotes a plug member, which has a cylindrical plug body 26 that closes the lower end surface and opens the upper end surface, and has a second outward flange 27 at the upper end of the plug body.
