Patent ID: 7946100

Claim:
A shrinking process for producing, transportable and printable containers for articles which are taller than they are wide and which include base surfaces and contain heat-sensitive filling substances, comprising: covering the articles to be packaged with a film such that the film ends overlap in the area of the base surfaces of the articles; heat sealing by heat transfer or convection overlapping ends in the area of overlap, and then heat shrinking the container in a shrinking oven, the container so produced being stabilized by the shrinking process; wherein incoming hot air is first locally limited to a base area of the container to form a peripheral shell in an area of the article bottoms, the shape of the container being stabilized thereby, and the container being continuously transported during stabilization, the hot air being directed onto the base area of the container in a bundle of discretely distributed gas jets from a gas circulation system and guided back to the gas circulation system after the locally limited heat transfer with the film, with additional hot gas being directed laterally against the container as it is continuously transported at an increased lateral blow speed in the shrinking oven in order to complete the shrinking process.
