Rotary actuated dispenser

A handheld rotary actuated product dispenser (10) that comprises a base member (1) and a replaceable cartridge (11), wherein:

• the base member (1) comprises:
• a cylindrical wall (1c) with an inner surface;
• an opened top (1a);
• a closed bottom (1b) with an inner surface;
• a circular gear (1f) that sits on the inner surface of the closed bottom (1b), and comprises a plurality teeth (1g);
• the replaceable cartridge (11) comprises:
• a container (3) that has:
• a top (3a) that supports a neck (3d), an opened bottom (3b) and a side wall (3c) that define a reservoir (3g) for housing a flowable product, wherein the side wall has an interior surface that is formed as a spiral thread (3f) that extends between the top and closed bottom of the container (3);
• a piston (4) located in the container (3), and having:
• a top (4a), an opened bottom (4b), and a side wall (4c) that has a spiral thread (4f) on its outer circumference, such that the spiral thread of the piston engages the spiral thread (3f) of the container (3);
• and
• a channel (4d) of non-circular cross section that passes through the top (4a) of the piston (4);
• a non-threaded drive shaft (5) comprising:
• a cylindrical member (5c) positioned in the opened bottom (3b) of the container (3), the cylindrical member having a closed top (5a) and an opened bottom (5b);
• two or more teeth (5g) located on the interior of the cylindrical member (5c);
• a spindle (5d) of non-circular cross section that extends from the top (5a) of the cylindrical member (5c), and passes through the channel (4d) of the piston (4);
• and
• a first applicator tip (6) attached to the top of the container (3) and comprising:
• a top (6a), a sidewall (6c) and an opened bottom (6b) that define an interior of the first applicator tip (6);
• a channel (6d) that depends from the top (6a) into the interior of the first applicator tip, wherein one end of the channel fits snuggly into the neck (3d) of the container (3);
• and the other end is formed as an exit orifice (6e);
• and
• wherein the bottom (3b) of the container (3) is fitted within the cylindrical wall (1c) of the base member (1), such that the two or more teeth (5g) of the drive shaft rest between teeth (1g) of the base member, and the base member and non-threaded drive shaft (5) are able to rotate as one relative to the container (3).
