Child resistant tip closure assembly with diaphragm

A child resistant closure for use on a container, said container having a threaded finish, said child resistant closure comprising:

• an inner closure member having:
• a threaded portion, said threaded portion being configured to threadedly engage the threaded finish;
• a base portion having said threaded portion;
• a cap portion extending from said base portion, said cap portion terminating in a distal cap end;
• a shoulder between the base portion and the cap portion, the shoulder includes a surface that surrounds the cap portion and is orthogonal to a longitudinal axis of the child resistant closure about which the child resistant closure is rotatable and compressible;
• a plurality of first engagement features extending from said shoulder of said inner closure member;
• an outer closure member having a sidewall and a distal end surface, said outer closure member being operably coupled to said inner closure member to permit limited axial translation along the longitudinal axis between said outer closure member and said inner closure member;
• a plurality of second engagement features extending from said outer closure member, said outer closure member being positionable in an operationally engaged position wherein said plurality of second engagement features engage said plurality of first engagement features to fix said outer closure member into rotation with said inner closure member, said outer closure member being positionable in an operationally disengaged position wherein said plurality of second engagement features are disengaged from said plurality of first engagement features to permit free rotational movement around said axis of said outer closure relative to said inner closure, movement between said operationally engaged position and said operationally disengaged position being along said longitudinal axis of the child resistant closure;
• a diaphragm member being disposed along said distal end surface of said outer closure, said diaphragm member being inwardly directed and contacting said distal cap end of said inner closure member thereby biasing said outer closure member into said operationally disengaged position;
• wherein the container includes a dispensing tip extending from the threaded finish, the base portion and the cap portion of the inner closure member are sized and shaped to sit over the dispensing tip when the threaded portion of the inner closure member is threadably engaged with the threaded finish;
• wherein said diaphragm member includes a central portion and a flexural member extending radially from said central portion to said distal end surface;
• and
• wherein said central portion comprises a contact surface, the longitudinal axis of the child resistant closure extends through a center of the contact surface, said contact surface contacting said inner closure member in said operationally engaged position at an axial center of said inner closure member through which the longitudinal axis of the child resistant closure extends, said flexural member being spaced apart from said inner closure member in said operationally engaged position.
