An assembly comprising a container, a container engaging member and a seal member, said container having a container body and an open neck, said open neck comprising a plurality of spaced, discontinuous open neck tabs extending radially from said neck;
- said container engaging member comprising a body having a neck engaging member, said neck engaging member comprising a plurality of spaced, discontinuous threads configured to engage with said spaced, discontinuous open neck tabs upon relative rotation of said neck and said neck engaging member;
- said container further comprising a circumferential flange extending radially outwardly from said neck, said flange comprising a plurality of spaced flange tabs;
- wherein said neck engaging member comprises a raised snap bead, a notch, and a raised stop member that are annularly aligned and cooperate with said flange tabs to create a snap fit engagement between said neck and said neck engaging member, said notch being positioned between said raised snap bead and said raised stop member, and wherein said seal member is positioned to engage said neck and compress upon relative rotation of said neck and said neck engaging member.
A method of engaging an engaging member with a container, comprising:
- providing a container having a container body and an open neck, said open neck comprising a plurality of spaced, discontinuous tabs extending radially from said neck;
- providing a container engaging member comprising a body having a neck engaging member, said neck engaging member comprising a plurality of spaced, discontinuous threads configured to engage with said spaced, discontinuous tabs upon relative rotation of said neck and said neck engaging member, said container further comprising a circumferential flange extending radially outwardly from said neck, said flange comprising a plurality of spaced flange tabs, and comprising at least one rotational limiting member extending axially from said neck engaging member, a raised snap bead, a notch, and a raised stop member that are annularly aligned and cooperate with said flange tabs to create a snap fit engagement between said neck and said neck engaging member, said notch being positioned between said raised snap bead and said raised stop member;
- providing a seal member;
- positioning said container engaging member over said container such that said at least one rotational limiting member is positioned in a region between said spaced, discontinuous tabs of said neck;
- rotating said container with respect to said neck engaging member 90° to engage said tabs of said container with said threads of said neck engaging member and compress said seal member to seal said container to said container engaging member.
