PROBLEM TO BE SOLVED: To effectively inhibit floating of an inner layer.SOLUTION: A cup shaped laminate bottle 1 comprises: an outer layer 2; and an inner layer 3 which houses a content, has excellent flexibility, and causes volume-reducing deformation as the content reduces. The inner layer 3 is laminated on an inner surface of the outer layer 2 so as to be peeled. Holding ribs 30, which sandwich the inner layer 3 and integrally hold the inner layer 3, are formed at a bottom part portion positioned at a bottle bottom part 12 out of the outer layer 2. A suction hole 31 for suctioning outer air into a space between the outer layer 2 and the inner layer 3 is formed at a part of the outer layer 2. One pair of holding ribs 30 is disposed at the bottom part portion in a manner that the holding ribs 30 are spaced away from each other with sandwiching a bottle axis O in a bottle radial direction. |
