Abstract
This invention provides a bottle that allows for easy and efficient application of shrink sleeves. The ease of application is partly a result of the invention's wall thickness along its body-forming portion. The body-forming portion of the invention has thick walls and thus exhibits negligible expansion during a hot-filling process. This permits a shrink sleeve to be placed onto the body-forming portion of the resistant bottle prior to filling. If the resistant bottle is hot-filled, the sleeve shrinks as a result of radiant heat emanating outwardly from the high temperature product, without the aid of an external heat source, such as a heat tunnel.
Claims2
A method for applying a shrink sleeve to a bottle without an external heat source comprising:
- placing a shrink sleeve onto the body forming portion of a bottle prior to filling;
- hot filling the bottle with a liquid;
- shrinking the sleeve as a result of heat emanating outwardly from the liquid;
- and
- capping the bottle;
- wherein the bottle comprises:
- an open-ended mouth forming portion;
- a body forming portion extending from the open-ended mouth-forming portion;
- a base portion;
- and
- the body-forming portion has substantially constant outer and constant inner diameters such that heat emanating from inside the vial during filling is equally distributed along the entire length of the bottle;
- wherein the body-forming portion has a minimum wall thickness of 1.5 mm to a maximum wall thickness of 4 mm.
