Abstract: A system comprising a bottle with a variable volume the outer side wall of which is deformable in the direction of the height and a device integrated into the inside of the bottle and retained in the latter to hold the bottle in one of a series of states of volume and to allow its gradual deformation from one state of given volume to another state of smaller volume, the system being applicable in particular to fizzy beverages.

Abstract: The depilating appliance comprises a series of hair-plucking grippers constituted by blades movably mounted on a support plate which is driven in rotation about a central shaft at right angles to the plate. The blades are disposed radially in one or a number of rows and placed in each row at right angles with respect to the corresponding radius of rotation. The blades are movably mounted on their support plate so that their free edges can be applied against each other or opened-out in the alternate sequence. During rotation of the support plate, closing and opening of the grippers take place at least once per revolution.
