Abstract
A package for fragile articles is disclosed and comprises a container that forms a solid polygon and two suspension frames in the container. Each of the frames are formed of a plurality of upright side panels and have at least one dimension that substantially spans and abuts the interior of the container so that each frame is prevented from moving in the container. At least two of said side panels are parallel, and each of which forms an arch, so that the arched parallel side panels are opposite one another. A resilient membrane is attached tightly to the edges of the side panels of each frame, and extends from the base of each arched side across the rise and span of each arched side. The frames are positioned in the container with the membranes in face to face relationship for holding an object suspended therebetween.
Claims22
A package for fragile articles and comprising:
- a container that forms a solid polygon and
- two suspension frames in said container, each said frame being formed of a plurality of upright side panels and having at least one dimension that substantially spans and abuts the interior of said container so that each said frame is prevented from moving in said container;
- at least one of said frames having two parallel side panels, and each of which defines an arch therein, so that said arched parallel side panels are opposite one another, and
- a resilient membrane attached tightly to said side panels of each said frame, and extending from the base of the arch of each said arched side panel across portions of the rise and span of the arch of each of said arched side panels;
- and
- said frames being positioned in said container with said resilient membrane in face to face relationship for holding an object suspended therebetween.
A suspension frame for packaging fragile objects and comprising:
- a plurality of upright side panels;
- at least two of said side panels being parallel and each of which defines an arch therein so that said arched parallel side panels are opposite one another, and
- a resilient membrane attached tightly to said side panels of said frame, and extending from the base of the arch of each said arched side panel across portions of the rise and span of the arch of each of said arched side panels.
A suspension frame blank for forming a suspension frame for packaging fragile objects, said blank comprising:
- a substantially rectangular planar sheet of corrugated board;
- fold lines in said sheet for defining four flap precursor portions along the four edges of said rectangular sheet;
- a central opening defined by said corrugated board sheet, said opening having two parallel side portions and two opposing curved end portions;
- and
- a sheet of flexible plastic film covering said central opening and attached to said planar corrugated board sheet.
