Container

A container comprising

• a container body, the container body having a first opening, a second opening, and a sidewall, the sidewall having a first end and a second end, the first end peripherally surrounding the first opening, the second end peripherally surrounding the second opening, the sidewall extending from the second end to the first end in a first longitudinal direction and from the first end to the second end in a second longitudinal direction, the sidewall comprising an inner surface;
• an interior void, the interior void peripherally surrounded by the sidewall inner surface and extending from the first opening to the second opening;
• a movable panel, the movable panel being adapted and configured to be retained within the interior void by the sidewall so as to divide the interior void into a first volume and a second volume, the first volume extending longitudinally from the movable panel to the first opening and the second volume extending longitudinally from the movable panel to the second opening, the movable panel being adapted and configured to be movable from the first end of the sidewall to the second end of the sidewall in the second longitudinal direction so as to increase the first volume from the second end of the sidewall to the first end of the sidewall in the first longitudinal direction so as to reduce the first volume while continuing to be so retained by the sidewall, the movable panel having a locking mechanism that comprises a manual actuator and a-sidewall engaging member, the locking mechanism being adapted and configured so that, when the manual actuator is actuated, the sidewall engaging member presses against the sidewall inner surface and frictionally engages the sidewall inner surface so as to resist manual removal of the movable panel from the container body in the first longitudinal direction, wherein;
• (1) the movable panel incorporates a baseplate;
• (2) the locking mechanism incorporates a locking member movably connected to the baseplate;
• (3) the sidewall engaging member is adapted to be disposed in a clearance that extends outwardly from the locking member to the sidewall;
• and
• (4) the manual actuator is adapted to be operative, when actuated, to move the locking member so as to reduce said clearance and to compress the sidewall engaging member between the locking member and the sidewall;
• and
• a cover, the cover being adapted and configured to be retained by the container body so as to cover the first opening so that the sidewall, the movable panel so retained by the sidewall, and the cover so retained by the container body enclose a storage volume, the cover so retained by the container body being manually movable to expose the first opening to allow manual dispensing of contents of the storage volume through the first opening, the storage volume comprising at least a portion of the first volume and the storage volume is configured to be reduced when the first volume is reduced by the movable panel being moved in said first longitudinal direction.
