In Euclidean $d$-spaces, the container problem
asks to pack $n$ equally sized spheres into
a minimal dilate of a fixed container.
If the container is a smooth convex body
and $d\geq 2$ we show that sequences of solutions to the container
problem can not have a ``simple structure''.
By this we in particular find that there exist arbitrary small $r>0$
such that packings with spheres of radius $r$
into a smooth $3$-dimensional convex body
are necessarily not hexagonal close packings.
This contradicts Kepler's famous statement
that the cubic or hexagonal close packing
``will be the tightest possible, so that in no other arrangement
more spheres could be packed into the same container''.
