1. A fluid tight safety container and cap combination including:
- a container having a neck portion comprising a generally cylindrical annular wall;
a cap having a base with a peripheral skirt projecting axially therefrom for receiving said neck;
interengageable locking elements on the outer wall of said container neck and on the inner wall of said cap skirt;
said container locking elements being spaced peripherally from each other; and
said cap locking elements being engageable with and disengageable from said container locking elements through combined axial and rotative motion of said cap relative to said container;
wherein the improvement comprisesan annular, flexible member formed on the distal end of said neck, as an axial extension thereof, and having an outer annular free end disposed in a plane perpendicular to said neck and said flexible member;
said annular flexible member having a stiffness to prevent axial deformation thereof;
said cap having means providing an annular sloping surface disposed between said base and said locking elements;
said cap sloping surface being engageable with said free end of said flexible member, to deflect said flexible member radially and thereby to exert an axial biasing force between said cap and container when said locking elements are engaged.

Abstract
A two piece combination of a container and cap, wherein the neck portion of the container and the flange of the cap have interengaging locking elements for securing the pieces together. A generally cylindrical flexible wall is an extension of the container neck, and terminates in annular free end perpendicular to the container neck. This annular free end engages an internally beveled surface of the cap, such that when the locking elements are engaged, the annular free end is deflected radially inwardly to provide an axially biasing force maintaining the elements engaged and also providing a seal between that member and the cap beveled surface.
