Benefits of technology

The invention is about a method and apparatus for producing a multi-compartment package using a vertical form, fill, and seal machine with a modified seal bar arrangement. The method involves forming a first end seal and a second end seal on a packaging film, filling each compartment with a different product, and optionally opening the open mouths of the compartments. The resulting package has a top and two separate compartments separated by a middle seal. The invention allows for the production of multi-compartment packages with separate compartments for different products or seasonings. The apparatus includes a product delivery tube, sealing jaws, and a discharge end. The horizontal form, fill, and seal machine includes a forming neck to convert packaging film into a folded web, and a cutter to produce a vertically oriented pouch with two compartments.

Problems solved by technology

At present, no known form, fill, and seal machine is capable of producing multi-compartment packages from a single tube of packaging film.

Embodiment Construction

[0022]One embodiment of the invention will now be described with reference to FIGS. 1-3. A vertical form, fill, seal packaging machine is seen diagrammatically in FIG. 1. This drawing is simplified and does not show the cabinet and support structures that typically surround a machine, but it does clearly show how the machine works. Packaging film 110 is unwound from a roll 112 of film and passed through tensioners 114 that keep it taut. The material that is fed into the form, fill and seal machine is typically a packaging film such as polypropylene, polyester, paper, polyolefin extrusions, adhesive laminates, and other such materials, or from layered combinations of the above. For many food products, where flavor retention is important, a metalized or barrier layer will form the inner most layer.

[0023]The film then passes over a former 116, which directs the film into a vertical tube around a product delivery cylinder 118. As the tube is pulled downward by drive belts 120 the vertic...
