A component for a storage container configured to receive vertically oriented articles, the component comprising: a tubular sidewall extending longitudinally from a base, said tubular sidewall comprising an inner surface and an outer surface, said base comprising a support surface and an underside; an interior region defined by said inner surface of said tubular sidewall and said support surface of said base, said interior region extending along a longitudinal axis and having a height dimension, a width dimension, and a length dimension; at least one spacer portion having an adjustable height dimension and extending from said underside of said base and configured for engagement with an interior surface of a corresponding storage container having an inner chamber; wherein said spacer portion includes a plurality of removable tabs, one or more of said removable tabs being selectively removable from a remainder of said spacer portion to vary said adjustable height dimension and correspondingly adjust the height of said component within said inner chamber of said storage container; at least one pair of retainer elements extending laterally from a portion of said inner surface of said tubular sidewall and inwardly into said interior region, said retainer elements of said at least one pair being oppositely oriented and configured to retain a vertically oriented article therebetween by frictional engagement with opposite longitudinal edges of said article; wherein each of said retainer elements comprises a tip portion sized and shaped to engage a corresponding one of said longitudinal edges of said article, said at least one pair of retainer elements sized and shaped for resilient deflection during insertion and during removal of said article therebetween, said retainer elements of said at least one pair being spaced apart sufficiently to removably receive said article therebetween having a nominal width between said opposite longitudinal edges, said retainer elements of said at least one pair being adjustable relative to one another to define a variable separation distance or angular orientation therebetween for engagement with a different vertically oriented article defining a different nominal width between opposite longitudinal edges thereof; and wherein an insertion force for resilient deflection of said retainer elements during said insertion of said article is less than a removal force for resilient deflection of said retainer elements during said removal of said article. a tubular sidewall extending longitudinally from a base, said tubular sidewall comprising an inner surface and an outer surface, said base comprising a support surface and an underside; an interior region defined by said inner surface of said tubular sidewall and said support surface of said base, said interior region extending along a longitudinal axis and having a height dimension, a width dimension, and a length dimension; at least one spacer portion having an adjustable height dimension and extending from said underside of said base and configured for engagement with an interior surface of a corresponding storage container having an inner chamber; wherein said spacer portion includes a plurality of removable tabs, one or more of said removable tabs being selectively removable from a remainder of said spacer portion to vary said adjustable height dimension and correspondingly adjust the height of said component within said inner chamber of said storage container; at least one pair of retainer elements extending laterally from a portion of said inner surface of said tubular sidewall and inwardly into said interior region, said retainer elements of said at least one pair being oppositely oriented and configured to retain a vertically oriented article therebetween by frictional engagement with opposite longitudinal edges of said article; wherein each of said retainer elements comprises a tip portion sized and shaped to engage a corresponding one of said longitudinal edges of said article, said at least one pair of retainer elements sized and shaped for resilient deflection during insertion and during removal of said article therebetween, said retainer elements of said at least one pair being spaced apart sufficiently to removably receive said article therebetween having a nominal width between said opposite longitudinal edges, said retainer elements of said at least one pair being adjustable relative to one another to define a variable separation distance or angular orientation therebetween for engagement with a different vertically oriented article defining a different nominal width between opposite longitudinal edges thereof; and wherein an insertion force for resilient deflection of said retainer elements during said insertion of said article is less than a removal force for resilient deflection of said retainer elements during said removal of said article.
