Method for making a flat trapezoidal container of brightly printed

Abstract

A flat trapezoidal container provides a generally frustoconical bag with a single cavity when at least partially filled with a pulverulent material such as soil which may have a live plant growing therein, or comestible goods such as popcorn and other snacks which rely heavily upon spur-of-the-moment purchases by a customer who must first be visually attracted to the goods, thereafter be visually convinced of their freshness, and have the opportunity to smell and/or touch the goods prior to purchasing them. The container may also be specifically dimensioned to snugly sheath a flower pot so as to leave therebeneath, a surplus of film in an empty transition zone which is concealable under the flower pot. The container is made from two flat panels of heat-sealable film, each shaped as a trapezium; or from a single web folded double. The lower portion of the container is ornamentally imprinted along a border extending beneath a generally lateral line above the longitudinal axis of the web, to identify the contents and simulate them in their optimum condition to enhance their marketability; and, with a marker in the upper portion, quantifies the volume of the goods contained, or provides instructions for their use. When the cavity is distended by being partially filled, the entire container, except for a transition zone, presents a smoothly arcuate surface of the frustum of a cone. The lower exterior portion is continuously printed with ornamental images of the contents, or images evocative thereof, without an interruption in the printing, such as is present as an elongated blank rectangle in prior art bags. The transparent upper portion is free from an elongated portion of the printed image near the edges, as in prior art bags. A method is disclosed for forming the printed container which method requires discarding the material for one bag for each bag made by thermally sealing the equally, but oppositely angulated sides of the trapeziums, and the shorter of the remaining parallel sides.
