A bag-in-box container is provided with a spout at an upper opening and a pressurizing element applying pressure to a flexible container. The pressurizing element includes two plate devices being urged apart by a resilient element. The two plate devices are provided with engageable hook elements that may be set out of engagement by shifting one of the plate devices with respect to the other along the plane of the plate devices; the shift causing all hooks to disengage simultaneously. This shifting apart action is performed from the side of the pressurizing element, facilitating disengagement from the side of the bag-in-box container. In one embodiment, a disengagement port is provided giving access to the pressurizing element, such that the at least two plate devices may be brought out of engagement with each other. The disengagement port may be a second opening on the side of the rigid casing.

Herein is disclosed an apparatus and method for delivering a fluid to an individual in such a manner that sloshing of the fluid is substantially suppressed, even when the fluid has been only partially consumed. The apparatus includes a reservoir for containing the fluid and a valve in fluid communication with the reservoir. A biasing mechanism exerts a force upon the reservoir, causing it to contract and force fluid through the valve, when the valve is opened. The biasing mechanism and reservoir are housed within a body, according to some embodiments.

The invention relates to a twist-action, portion-control dispenser having a dispenser body, a grip ring attached to an exterior surface of the dispenser body, and a piston movably fitted within the dispenser body and coupled to the grip ring. The piston is configured to move incrementally downwards through the dispenser body when the grip ring is rotated relative to the dispenser body. A sauce pouch is contained within the dispenser body, in contact with the piston, such that sauce is dispensed from the dispenser as the piston is moved incrementally along the body.

A cartridge case includes a case, a spout support portion, a mount portion, a roll-up member, and a lock member. The case includes a first face extending in a first direction. The spout support portion is configured to support a spout provided in a liquid container containing an inkjet liquid. An end portion on a first direction side of an elastic member is mountable in the mount portion. The elastic member generates an energizing force in the first direction. The roll-up member is configured to roll up the liquid container by being moved in the first direction by the energizing force of the elastic member. The lock member is configured to lock movement, in the first direction, of the roll-up member. The lock member is configured to release lock of the roll-up member, based on consumption of the inkjet liquid contained in the liquid container.
