ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to the packaging of oil-coated cutting tools, such as drill bits, taps, dies, cutters of various kinds, hobs, end mills, carbide tools and reamers.
Traditionally, drill bits and other cutting tools are packaged for sale in simple cardboard envelopes or pouches, with a latex-sealed flap. A problem with the prior art approach is that, for protection against rust and discoloration, the cutting tools are dipped in oil prior to packaging. Subsequently, the oil bleeds through the cardboard, degrades the glue used to hold the cardboard pouch together, and can soak through adhesive labels on the cardboard pouch, and the labels tend to drop off.
Despite these disadvantages, cutting tools continue to be packaged in cardboard envelopes.
SUMMARY OF THE INVENTION
In an exemplary embodiment, an oil-coated cutting tool is packaged by providing a package blank which includes a pair of panels of heat-sealable and oil-impervious material defining a product-containing area between them. The panels have edges defining a package top, bottom and opposite sides. The panels are permanently sealed to each other along the side-defining and top-defining edges, and there is an opening along the bottom-defining edges. The package blank additionally includes a zipper-type recloseable strip in the form of an interlocking bead structure, which effects an openable and recloseable seal between the panels. The interlocking bead structure extends across the panels generally from one of the side-defining edges to the other, and is spaced a distance from the top-defining edge to define a tear zone portion of the panels between the top-defining edge and the interlocking bead structure. The oil-coated cutting tool is inserted through the opening into the product containing-containing area, and the panels are permanently sealed to each other along the bottom-defining edges so as to close the opening.
