Abstract: A flipper assembly that can be used with a package-producing mold, for instance, a mold that is used during thermoforming procedures. The flipper assembly includes a base mounted to the mold, a flipper arm pivotably connected to the base between a first position where the arm is substantially perpendicular to the height of the base and a second position where the arm is substantially parallel to the height of the base, and a spring mounted to the base and the flipper arm. During the thermoforming process, the flipper arm forms an undercut of finger into the package, which improves the stability and strength of the package. The flipper arm is moved between first and second positions based on linear extension and retraction of the spring.

Abstract: A reclosable package having a blister with an outer wall defining an article-holding cavity in communication with a cavity opening that includes a door attached by a hinge and configured to seat in the opening with engagement between the door and a cavity-opening defining side or edge helping keep the door closed. In one embodiment, the door includes an indented portion that frictionally engages at least one and preferably a plurality of cavity-opening defining side when closed. Such an indented portion can include an undercut that underlies part of the adjacent cavity-opening defining side when the door is closed having an interference fit therebetween that can be a snap fit. The package can also be configured to provide releasable engagement between part of the door and part of the blister outer wall when the door is closed that can be in the form of a bar snap.

Abstract: A transparent carton of long thin shape for wiper blades, including an integral hinge connecting a cover section to a bottom section along its entire length, interfitting flanges on the bottom and cover sections which, when engaged to close the package, provide an interlocked full length closure which can readily be opened and reclosed. The cover section also includes a plurality of small shelves in its interior, adjacent its main panel, to retain a display card. One of the main panels of one of the carton sections may incorporate suitable measurement scales. One end of the carton also may include a hanger means for hanging the packaged wiper blades on pegs of a display rack.
