Dispensing closure

A dispensing closure (40) for a system (44) having an opening (46) between an exterior of the system (44) and an interior of the system (44) where a fluent substance may be stored, said dispensing closure (40) comprising:

• A. a closure body (54) that
• 1) can be located at the system opening (46) and that defines an inlet (74) for communicating with the system,
• 2) has an end (70) defining an aperture (84) to accommodate the flow of a fluent substance through said closure body (54);
• B. a locking member (56) mounted on said closure body (54) for rotation about a central rotational axis (A), said locking member (56) having an intermediate flow passage (140) for accommodating the flow of a substance through said closure body aperture (84), said locking member (56) having
• 1) a locking position, and
• 2) an unlocking position rotated about said central rotational axis (A) away from said locking position;
• and
• C. an actuator (60) that
• 1) is rotatably mounted to said locking member (56) for occluding said locking member intermediate flow passage (140) to prevent flow of a fluent substance through said closure (40) when said actuator (60) is in a closed, non-dispensing position and for permitting flow of a fluent substance through said closure (40) when said actuator (60) is rotated to an open, dispensing position,
• 2) includes a dispensing flow passage (190) that is in communication with said intermediate flow passage (140) of said locking member (56) when said actuator (60) is in said open, dispensing position, and
• 3) is in engagement with a portion of said closure body (54) when said locking member (56) is in said locking position to prevent said actuator (60) from moving into said open, dispensing position;
• and
• wherein said actuator (60) includes at least one downwardly extending abutment (216) and said closure body (54) includes an upwardly extending abutment (110) whereby said downwardly-extending abutment (216) and said upwardly extending abutment (110) are oriented to engage to prevent said actuator (60) from moving into said open, dispensing position when said locking member (56) is in said locking position;
• and
• wherein said upwardly extending abutment (110) of said closure body (54) has a radius of curvature centered on said central rotational axis (A), and said downwardly extending abutment (216) of said actuator (60) has a length extending an oblique angle relative to said radius of curvature.

• and
• wherein locking member (56) includes an outer wall (114) surrounding said intermediate flow passage (140), all of said outer wall (114) is located radially inward of an outermost surface of a body wall (71) of said closure body (54).
