An improvement for a tamper evident resealable cap for use on a bottle, the cap having an upstanding spout that is registerable with an opening in the center of the cap and a sealing plug of a smaller diameter positioned thereabove on multiple upstanding legs extending from the spout. The improvement is directed towards a detachable annular ring secured to the cap by a plurality of frangible elements thereabout, the ring is arranged for restrictive registration with a locking shoulder that extends from the top of the cap body. The cap body has a tamper evident band secured to the cap by a plurality of circumferentially spaced frangible elements with a plurality of annularly spaced radially inwardly extending annular projections and is registerable with a neck portion of the bottle to prevent rotation in one direction without removal of the tamper evident ring.
An improvement in a tamper evident resilient resealable molded plastic bottle cap for a bottle having a neck surrounding an opening, said neck having a spiral thread thereabout, a cap having a top portion, a depending annular flange extending from said top portion, a spiral thread in said annular depending portion, an annular sealing flange depending from said top portion in spaced relation to said depending annular flange, a tamper evident band extending from a plurality of annularly spaced frangible elements on the depending annular flange, circumferentially spaced radially inwardly extending angular projections on said tamper evident band facing said bottle neck, said neck having ratchet sections registerable with said angular projections on said tamper evident band, an integral spout on said top portion in communication with an opening in said top portion, an aperture in said spout registerable with a secondary movable top cap on said spout, a plug extending from said spout above said opening registerable with an opening in said secondary top cap defining a closure when said top cap is moved in a first position, the improvement comprises a tamper evident ring having a plurality of frangible elements connecting said ring to said top cap of said cap in said first position, an upstanding retaining flange on said top portion in spaced relation to said pour spout retaining said tamper evident ring thereunder when said top cap is in said first position when said top cap is moved away from said first position to a second position said opening in said top cap in spaced relation to said plug.
An improvement in a tamper evident resilient resealable molded plastic bottle cap for a bottle having a neck surrounding an opening, said neck having a pair of vertically spaced annular flanges extending therefrom, the cap having a top portion, a depending annular flange extending from said top portion, an annular retaining bead extending inwardly from said depending annular flange in spaced relation to said top portion, an annular flange depending from said top portion in spaced relation to said depending annular flange, and a tear band extending from said depending annular flange having a tear tab integral therewith, an integral spout on said top portion in communication with an opening in said top portion, an aperture in said spout with a secondary movable top cap positioned thereon, a plug extending from said spout above said opening registerable with an opening in said secondary top cap defining a closure when said top cap is in first position, the improvement comprises a tamper evident ring having a plurality of frangible elements connecting said ring to said top cap of said cap in said first position, an upstanding retaining flange on said top portion in spaced relation to said pour spout retaining said tamper evident ring thereunder when said top cap is in said first position when said top cap is moved away from said first position to a second position positioning said opening in said top cap in spaced relation to said plug.
