MULTI-COMPARTMENT BAG

摘要

A method is disclosed for forming a two-compartment bag. The method comprises draping a sheet of bag forming material around a primary fill pipe and one or more secondary fill pipes, forming multiple compartments by sealing the sheet material around the respective fill pipes, filling the various compartments with material, and sealing the bag.;The method comprises forming transverse seals so that a transverse seal area of a secondary compartment at least partially overlaps with a transverse seal area of the first compartment, so that the secondary compartment is fixedly folded against the first compartment.;The method permits the volume of the secondary compartments to be varied independent from the volume of the primary compartment. Each compartment may be opened without opening the other compartments.;In a preferred embodiment the bag is made of a microwave-compatible material, and at least one of the compartments contains a food material intended for reheating or preparation in a microwave oven.

1. A method for forming a multi-compartment bag comprising the steps of:
a. draping a portion of a continuous sheet 11 of bag forming material around a primary fill pipe so that two plies of the sheet meet inward of a first and a second longitudinal edge along a first seal line, leaving flaps extending beyond the first seal line to the first and second longitudinal edges of the sheet; b. draping the flaps around at least one secondary fill pipe so that the first and second longitudinal edges of the sheet meet at a second seal line; c. forming longitudinal seals along the first and second seal lines; d. forming a transverse seal comprising transverse seal areas below the primary and secondary fill pipes to form a bag having a first compartment encircling the first fill pipe and at least one secondary compartment encircling the secondary fill pipe or fill pipes, so that a transverse seal area of the at least one secondary compartment at least partially overlaps with a transverse seal area of the first compartment; e. metering a primary material into the first compartment and one or more secondary materials into the secondary compartment or compartments.
