Closure and security ring for containers

In a container assembly having (i) a container outer surface having a round closure portion about a round container opening and having an outwardly extending flange portion positioned between the closure portion and a remainder of the container outer surface and wherein the closure portion has screw-thread ramps for engaging a screw-thread cover for providing for closing and opening the container and (ii) a cover having a first portion for covering the container opening and a round skirt portion which depends laterally from the first portion to a circular skirt edge to define, together with the first portion, a cover interior and wherein the skirt has screw-thread ramps positioned for engaging the container ramps for providing for closing and opening the container, the improvements comprising:

• (i) a ring comprising a rim and two sets of spaced-apart lugs wherein the lug sets have differing shapes and wherein the lugs extend from the rim and (ii) a skirt interior portion which extends between the skirt edge and the cover screw-thread ramps and which contains a perimeter groove at a position displaced from the skirt edge and wherein the rim has a surface which abuts the skirt edge, wherein one lug set comprises two lugs which extend from the rim to the groove to lock the ring member to the skirt and wherein the second lug set comprises at least one lug which extends from the rim to the container and wherein the container and the cover and the second lug set are configured so that the flange is positioned between the cover screw-thread ramps and the edge, so that the interior skirt portion and the groove are spaced a distance away from the container remainder portion and so that upon turning the cover to open the container, the second lug set contacts the flange and establishes a tension for breaking the rim.
