Benefits of technology

The present invention provides a reclosable package that can be opened and closed repeatedly, and can be converted between a pre-filled and post-filled condition. The package includes a fastener with male and female tracks that are interlocking, and a slider for easy opening and closing. The package is made from a web of plastic material that is folded to create panels joined along sides and bottom, with a fill opening for easy filling and sealing. The invention also provides an apparatus for performing the methods described above. The technical effects of the invention include improved sealing, easy opening and closing, and efficient production and conversion.

Problems solved by technology

The bottom gusset, however, makes it less practical to provide a fill opening at the bottom because most of the product resides in the gusset.

Abstract

A fill-through-the-top reclosable package includes first and second opposing body panels joined to each other along a pair of sides and a bottom bridging the pair of sides. The package is provided with a reclosable fastener extending along a package top disposed opposite the bottom. The fastener includes first and second opposing tracks. The first track includes a male profile, while the second track includes a female profile adapted to releasably interlock with the male profile. To provide tamper evidence, the first and second tracks may be joined to each other along an area of weakness. When making the package, the first track is first attached to the first panel, the package is filled with a product via a fill opening between the second track and the second panel, and then the second track is attached to the second panel.
