Abstract: This invention relates to the provision of a package having interengaging members which, when engaged with similar such members, nest within each other. Load applied to the top of such a package is transferred down an interengaging member into a similar interengaging member on the base and further to a similar interengaging member on a package below. A stack of such packages will allow the load of the stack to be transferred directly through the interengaging members to the support base on which the stack resides.
