Abstract
This invention relates to a packaging method and device utilizing heat-shrinkable thermoplastic film for bundling a plurality of prepackaged containers which allows for access to a carrying means on the prepackaging. The packaging method and device forms a means of bundling a plurality of containers which have been prepackaged into units. Further, the heat-shrinkable thermoplastic film device forms a protective shielding for the prepackaged containers so bundled.
Claims13
A method of bundling a plurality of packages having one or more containers therein and providing for access to a carrying means comprising:
- a) placing a plurality of packages having one or more containers therein and having a carrying means, in a desired position;
- b) surrounding said plurality of packages with a heat-shrinkable thermoplastic film;
- c) shrinking said heat-shrinkable thermoplastic film around said plurality of packages using a heat shrinking means;
- and
- d) providing access to the carrying means through the heat-shrinkable film using a hot tool cutting means;
- characterized in that the hot tool cutting means simultaneously cuts an access hole of a size sufficient to permit hand access therethrough and provides a weld around the periphery of said access hole thereby substantially eliminating tear propagation in the heat-shrinkable thermoplastic film.
A packaging device comprising a heat-shrinkable thermoplastic film, heat shrunk around a plurality of prepackaged containers and having a carrying means access means comprising a hole cut into said heat-shrinkable thermoplastic film of a size sufficient to permit hand access therethrough using a hot tool means and having a weld around the periphery of said access means to substantially eliminate tear propagation.
