Container whose side wall includes a surface discontinuity to hold shrinkwrap thereto
A container having a shrinkwrap layer. The tapered container side wall includes a surface discontinuity which maintains the shrinkwrap in place against the container side wall(s) after the shrinkwrap has been substantially separated from the lid and rim of the container. Whether the shrinkwrap layer minimally hangs over the lid of the unopened container, or whether it entirely covers the lid, the shrinkwrap nonetheless clings to the side wall(s) after the shrinkwrap is torn and separated from the lid and rim of the container. Various configurations of the surface discontinuity are disclosed, such as a ridge extending around the lower periphery of the side wall, a bulge extending around the side wall, a series of indentations or a series of protuberances disposed about the side wall of the container. Further, the inventive surface discontinuity can be employed in a variety of container shapes and sizes.
1. A method of opening a container for storing items comprising the steps of:
a) providing a nestable container, wherein the container comprises:
a container bottom;
a side wall extending upward from said bottom and terminating in a rim defining the periphery of said container, said side wall tapering from top to bottom such that the container can nest with one or more like containers when lids are not covering the containers;
a lid releasably covering said container;
an annular surface discontinuity disposed on said side wall intermediate said rim and said container bottom;
a tubular layer of shrinkwrap enveloping said tapered side wall and an outer periphery of the lid thereby securing the lid to the side wall; said shrinkwrap being separable from the lid and rim; and
a non-adhesive label trapped between the shrinkwrap and the side wall; and
b) separating the shrinkwrap from the lid and rim while said layer of shrinkwrap is formed to and covers said surface discontinuity and conforms to the shape of the surface discontinuity thereby holding the enveloping shrinkwrap in place on the sidewall when the lid is removed while the non-adhesive label is trapped between the shrinkwrap and the side wall, said label remaining trapped after the lid is removed.
2. The method of claim 1 , further comprising the step of adhesively affixing a label to the outside of said shrinkwrap layer about said side wall.
3. The method of claim 1 , wherein said shrinkwrap layer comprises an integral piece of shrink wrap.
4. The method of claim 1 , wherein said shrinkwrap layer totally covers said lid.
5. The method of claim 1 , wherein said surface discontinuity comprises an indentation.
6. The method of claim 5 , wherein said indentation is proximal to the container bottom.
7. The method of claim 1 , wherein said surface discontinuity comprises a plurality of indentations disposed on said side wall.
