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.

Abstract: A self-adjusting handle (2) for a spray bottle (1) having a head (5) extending from a handle (2) that is attached to a cap (6) via a pivot joint (4), a ball joint (15) or a universal joint (20). The cap is attached to a reservoir (7) having a threaded portion that screws into a threaded portion (13) of the cap. A trigger lever (8) located on the head activates a pump (9). The pump is attached to a supply tube (10) that draws fluid from the reservoir. The pump 9 forces liquid up through the supply tube, through a barrel (11) and out a nozzle (12). The pivot joint, a ball joint and universal joint allow a user to pivot the head forward or backward while the reservoir remains in an upright position, thereby ensuring that the bottom of the supply tube maintains constant contact with the liquid in the reservoir.
