A container for a spillproof assembly has a main body which is substantially round is viewed in top plan, with a first wing 24 protruding from a side. The container may have a second wing 26 on the other side, with matching first and second wings 16, 18 on the lid. Lid wing 16 may have a view window 38, through which, a snap ridge on the container first wing 24 may be seen, to check the lid has been tightened properly. An acoustic waveguide (figs 4, 10 & 11), with communicating sound generating structure 38, may create an audible click when the lid has been tightened onto the container. The acoustic waveguide acts as the viewing port 38 so that a user can visually verify the position of the lid body. The wings of lid body may slightly interfere with and cam over respective upper platforms on the wing portions of the container body so that a user will be provided with a tactical feedback as a lid body is approaching an optimal amount of tightness. The wings may enhance the grippability of, and properly orientate, the container assembly for small children. |
