Abstract:

A vertical form, fill, and seal packaging system may comprise a source of flexible thermoplastic packaging material, a tubular folder, a product dispenser of the tubular folder, and a side sealer. The source of flexible packaging material in an elongated thin flat strip of material may comprise successive flat package blanks as integral longitudinally contiguous sections. The tubular folder may be adapted to receive a strip material and progressively forms in passage to a depending and upwardly open tubular configuration, with opposite longitudinal edge portions of the material being progressively juxtaposed in a passage so as to extend in vertical and parallel directions. The product dispenser of the tubular folder for discharging measured quantities of materials may be through a fill tube extending downward into an interior of the depending tube of packaging material through an upwardly open end. The side sealer may be used for sealing the juxtaposed vertically extending longitudinal edge portions of the tube. A method of making packages may comprise the steps of folding a single sheet of thermoplastic film into a tube; sealing an open vertical end or side around a filing tube; tucking gussets; sealing bottom; and filing an opened cavity of package with a hot material at 160 F. or greater.

Abstract:

A blow-molded plastic container having a body comprising a neck portion, a generally cylindrical sidewall portion and a bottom structure. The bottom structure comprises a central portion, a plurality of ribs extending downwardly from the bottle sidewall to the central portion, and a plurality of feet extending below the central portion from the sidewall portion. The ribs are defined by an upper curvilinear surface and, in cross-section are of an substantially U-shape having a relatively tight radius, the upper rib surfaces lying on a generally hemispherical curvature in the interior of said container. Each foot is positioned between two ribs and has a pair of rib-defining endwalls connected to and continuous with the ribs on each side of a curvilinear outer wall connected to and continuous with the sidewall portion, a generally horizontal base surface joined to said outer wall, a generally vertical first inner surface forming a lip extending upwardly from the base surface, and a second inner surface extending from the lip to the central portion.
