Abstract: A vessel defining a variable interior volume has a wall with a first and second wall portion, and a flexure zone parallel to a longitudinal axis. In a volumetrically reduced configuration, the wall portions are brought together by flexing of the flexure zone. A fixing element attached to the wall releasably maintains the wall in the reduced configuration by maintaining proximity of the wall portions. A spray bottle system includes a housing forming a receptacle for receiving a soft refill liquid container and having at least one opening representing a reduction in material of the housing. A spray head includes an operable trigger for causing dispensation of liquid from the container. A pivoting junction connects the housing to the spray head permitting flexing of the spray head.
