Container safety dispensing closure

Claim 1

A container safety dispensing closure comprising: a. a hollow outer cap having a generally cylindrically shaped outer wall and a flat top, the wall having an inwardly opening circumferential slot on a lower portion thereof, the outer cap adapted to be securely fixed to the container by a retaining ring cooperatively received by said slot and a matching outwardly opening circumferential slot on the container, the wall having a first dispensing aperture extending therethrough substantially diametrically opposite a seat opening, the flat top having a circular central hole extendinG therethrough; b. a hollow generally cylindrically shaped inner cap rotatably received within the outer cap in sliding contact with an upper rim of the container, the inner cap having a second dispensing aperture adapted to be aligned with the first dispensing aperture in the outer cap, the inner cap having a circular seat located beneath the circular hole in the top of the outer cap, the circular seat being smaller in diameter and in eccentric alignment with the circular hole, the inner and outer caps adapted to be engaged by a separate wall mounted opening tool having a manually rotatably cylindrical shaft with a smaller diameter cylindrical boss eccentrically located on one end thereof, the said circular seat adapted to receive the said end of the shaft and the circular seat adapted to receive the eccentric boss in an engaged position wherein manual rotation of the shaft correspondingly rotates the inner cap within the outer cap whereby the inner cap may be rotated from a closed position wherein the second dispensing aperture is covered by the wall of the outer cap to an open position wherein the first and second dispensing apertures are in alignment, thereby providing a passage for dispensing of the contents of the container by tilting the container, the inner cap having a flat vertical outer segment radially opposite the second dispensing aperture; c. a torsional spring located between the inner and outer caps with one end engaging the inner cap and the other end engaging the other cap whereby the inner cap is subjected to a continuous rotational bias towards the closed position; d. a pushbutton member horizontally reciprocatingly received in the seat opening in the outer cap, the pushbutton member having a flat inner surface adapted to be brought into bearing contact with the flat outer segment of the inner cap by depressing the pushbutton member to manually retain the inner cap in the open position following disengagement of the opening tool, the torsional spring immediately returning the inner cap to the closed position upon release of the pushbutton member.
