Abstract: A changeable sink strainer in a drain opening of a sink has a strainer body installed between the sink and a waste pipe. A threaded receiver including a flanged nut is mounted within and at a lower end of the strainer body. A decorative insert is removably disposed within the strainer body. A hollow securing element, e.g. a screw or bolt, removably engages a lower end of the decorative insert within the strainer body and threadably engages the threaded receiver to removably secure the decorative insert to the strainer body. A basket strainer with a depending stem retains the basket strainer within the strainer body. The stem has a retractable element for removably retaining the stem in the hollow securing element.

Abstract: Collapse-resistant paperbox packaging for small articles, comprising an outer paperbox shell and an inner corrugated paperboard sleeve removably encased within said paperbox shell, said corrugated paperboard sleeve having a transparent plastic skin laminated thereto with an article secured between them, and said corrugated paperboard sleeve having upwardly extending flanges which juxtapose side panels in the paperbox shell. The corrugated paperboard sleeve reinforces the paperbox shell and combines with it to provide a strong box construction highly resistant to collapsing. A window is provided in the paperbox shell so that the article may be exposed to view through said window and through the transparent plastic skin.
