Package for plural reactable components with rupturable ultrasonic seal

Abstract

Abstract A package for two component system which requires separate, secure storage with rupture of an internal seal to permit mixing of components at the time of use is provided by having at least one and preferably three, ultrasonic seals dividing a laminate film package into compartments, with a perimeter heat seal around the edges of the package, and which seals the ends of the the ultrasonic seals after formation. The space between the ultrasonic seals is a security compartment, and may contain a dye to indicate leakage into the compartment. The compartments contain components for resins, pharmaceuticals, or chemiluminescent systems, or the generation of heat, generation of cold, or photographic processing solutions. Ultrasonic sealing permits a reliable chemical proof seal of predictable and controllable rupture characteristics. The two compartments contain storage stable components, which react on mixing. The compartments can be generated continuously from continuous strip material in rolls, with edge and barrier seals being continuously formed, and filling nozzles extending into the tubes formed by the sealing. By severing and sealing, a series of double filled compartment packages are continuously formed.
