A dispenser for dispensing a fluent product;
- the dispenser comprising:
- a container comprising;
- an upper part, having
- a side wall with a cylindrical inner surface;
- a ceiling connected to the side wall at an upper end of the upper part;
- and
- a ceiling opening through the ceiling;
- and
- a lower part, having
- a side wall with a cylindrical outer surface;
- a floor connected to the side wall at a lower end of the lower part;
- and
- a floor opening through the floor;
- the cylindrical outer surface is configured to fit into the cylindrical inner surface;
- the cylindrical inner surface and the cylindrical outer surface having a mutual longitudinal axis;
- and
- a bag configured to fit into the container and filled with the fluent product to be dispensed, the bag comprising;
- a bag upper end having a bag opening;
- a bag lower end;
- a skin between the bag upper end and the bag lower end made of a flexible and resilient material;
- an upper member coupled to the bag upper end having a nozzle with a threaded nozzle screw extending upwards from the upper member;
- wherein the bag opening is connected to the nozzle;
- wherein the threaded nozzle screw is configured to fit into the ceiling opening;
- and
- a lower member coupled to the bag lower end having a threaded screw extending downwards away from the lower member;
- wherein the threaded screw is configured to fit into the floor opening;
- the upper member coupled to the ceiling, and the lower member coupled to the floor;
- the container further comprising a rotational ratchet mechanism having a plurality of elastic fins protruding diagonally outwards from the cylindrical outer surface, and a plurality of ramp shaped grooves extending along an entirety of the cylindrical inner surface in a direction parallel to the mutual longitudinal axis while the plurality of elastic fins extending along a longitudinal portion of the cylindrical outer surface;
- the plurality of ramp shaped grooves are configured to receive the plurality of elastic fins when the upper part and the lower part of the container are fit together;
- wherein the rotational ratchet mechanism only allows a unidirectional rotation of the upper part relative to the lower part of the container,
- wherein the rotational ratchet mechanism also allows for a vertical displacement of the upper part relative to the lower part of the container;
- wherein, rotation of the upper part of the container relative to the lower part of the container, which in turn twists and collapses the bag internal to the container, causes the floor of the lower part to move closer to the ceiling of the upper part, while dispensing the fluent material via the nozzle.
