A tamper evidencing or evident closure for a container having a dispensing orifice includes separately formed cap and base sections, the base section engaging an opening of the container and including an orifice member through which contents of the container are dispensed, the cap section including a skirt to which a cap is hingedly attached and a pair of tear strips formed around a lower edge of the cap member that are frangibly connected between the cap and the skirt portion so as to prevent opening of the cap without breaking of connections between the tear strip and the cap. A pull ring concentrically formed about the cap member and attached to ends of the tear strips, but not attached to the cap member, is included so that the tear strips can be torn away from the cap and skirt by simply pulling up on the pull ring.

A tamper evident closure for a container having an opening for dispensing contents therein, comprising: (a) a base section engaged within said opening, said base section including a central plate section that covers said opening, an orifice in said central plate section, an annular wall that depends downwardly from said central plate section such that an outside diameter of said annular wall engages an inside diameter of said opening, and a flange that extends radially outward from said annular wall and over a top edge of said opening, said flange forming a horizontal surface at a level below that of an upper surface of said plate section; (b) a skirt member adapted to engage about said opening in non-removable fashion and to retain said base section in engagement with said opening, skirt member including an inwardly extending flange that overlays said outwardly extending flange of said base section, a circumferential groove that rings an inside diameter of said skirt member so as to capture said radially outwardly extending flange of said base section, and a circumferential bead that also rings the inside diameter of said skirt member so as to engage beneath an outwardly directed bead on an outside diameter of the top edge of said opening; (c) a cap member hinged attached to said skirt member by means of a living hinge member, said cap member adapted to move between opened and closed positions and including a stopper member on said cap member adapted to engage said orifice in said central plate section when said cap member is in its closed position, said cap member being positioned on said central plate section in its closed position; (d) a pair of tear strips connecting said cap member and said skirt member by means of integrally molded frangible connections to both said skirt member and said cap member, said tear strips being shaped so as to follow a contour of a lower edge of said cap member and connecting between said inwardly extending flange of said skirt member and said lower edge of said cap member, said tear strips precluding movement of said cap member to its open position without breaking of said frangible connections; and (e) a grasping member attached to said tear strips and elevated above said skirt member, said grasping member substantially comprising a ring concentrically positioned about a top edge of said cap member and including two downwardly depending legs that extend down to and attach to terminal ends of said tear strips positioned adjacent opposite sides adjacent said living hinge member so that said frangible connections can be broken by grasping and upward pulling of said ring member.
