Machine for Creating and Filling a Multi-Compartment Pouch Simultaneously with Powder and Liquid

摘要

A packaging machine forms, fills and seals a mixing pouch that includes a first compartment containing a liquid ingredient and a second compartment containing a light powdered ingredient with a breakable seal, preferably formed by an adhesive heat seal, between the two compartments to separate the two ingredients. The machine creates a breakable seal that can be ruptured to form a common interior cavity and allow the mixing of the two ingredients to create a mixed product. One end of the mixing pouch can be formed with a dispenser through which the mixed product is discharged for use. The mixing pouch is a flexible plastic member formed from two opposing plastic sheets, sealed through heat dies and supplied with powdered and liquid components before being completed. The operation of the machine is automated and powered through pneumatic cylinders. Alternatively, the compartments could be filled with different liquid components.

主权项

1. A machine for forming and filling a pouch having different component materials in at least two compartments separated by a breakable seal, comprising:
a pair of opposing supplies of material having characteristics allowing the supplies of material to seal together upon an application of heat; a feed mechanism engaged with said supplies of material to present opposing spans of said material in a converging angular orientation; a heated die positioned at the convergence of said opposing spans of material and selectively engaging said opposing spans of material and forming seals that define a pouch having at least two compartments, said seals including a lower and side exterior perimeter boundary seals and an interior seal located between said compartments; at least two component fill mechanisms selectively operable to insert said different component materials respectively into said at least two compartments, said feed mechanism advancing said pouch and said opposing spans of material such that an upper portion of said pouch is engaged by said heated die to form upper boundary seals to close said compartments; and a severance mechanism to sever said pouch from said spans of opposing material after said upper boundary seals have been formed.
