Patent ID: 8875920

Claim:
A beverage container comprising a container body including an opening, a cap to close the opening, and a collar mountable on the container body, the container body including a radially outwardly projecting rim beneath which the collar can be retained on the container body until removal of the cap, the collar comprising a plurality of flaps or other parts spaced-apart from each other along a circumferential extent of the collar, the cap and the collar including a plurality of circumferentially spaced thread parts by which the cap may be secured to the collar, thereby securing the cap to the container body when the collar is mounted on the container body, wherein the cap is shaped at a plurality of circumferentially spaced positions around its interior so as to press and/or hold said flaps or other parts of the collar by a camming action radially inwards as the cap is rotated relative to the collar so said flaps or other parts of the collar are secured beneath the rim of the container body, wherein the cap, the collar and the container body are configured such that removal of the cap from the container body causes removal of the collar from the container body, the container body having a plurality of spaced apart ribs beneath the outwardly projecting rim, one side of each rib having a ramp, whereby rotational movement of the collar in a loosening direction with respect to the container body causes each of said flaps to ride up a respective ramp so flexes the flaps outwardly to disengage them from said rim thereby releasing the collar from the container body.
