Abstract:
A plastic container package, comprising:a first generally hollow, substantially hemi-spherical shell member formed by a wall having an annular rim element defining a cylindrical thickening annulus of a select length with a first end associated with a recessed ledge and a second end, said annular rim thickening from said first end toward said second end, said annular rim element having a generally circular configuration with a substantially smooth inner surface and a second outer substantially smooth surface;a second generally hollow, substantially hemi-spherical shell member formed by a wall, said second member having an annular lip element with a generally circular periphery defining a surface corresponding in dimension and diameter to cooperate with the smooth inner surface of said annular rim element of said first shell member, said annular lip element adapted to juxtapose and overlap said angled outer surface of said rim element of said first shell member to establish an interference fit between said lip element of the second shell member and said rim element of the first shell member, so as to provide a frictional compression fit established by camming engagement to separably connect the first and second hemispherical members to form a substantially hollow spherical packaging container providing enhanced resistance to random separation of the first and second shell members.
