Definitions

  • This invention relates to cooling or freezing an article or a bundle of articles after the article has been filmed wrapped and heat shrunk.
  • the term article refers to a bundle of articles such as bottles or a single article. These articles are perishable and require a cooled environment.
  • the prior art has placed articles in cartons, having holes in the carton, to allow cold air to circulate in the carton during the freezing or cooling of the articles.
  • This technique of cutting holes in the heat shrink film for air circulation of the article has been tried without success. Cutting the holes mechanically with an heated die or heat while the heat shrink material is moving resulted in hole sizes of less than about 3 ⁇ 8 inch.
  • the prior art was in need of a commercial viable way of creating openings large enough to allow sufficient air circulation to cool or freeze articles wrapped with a heat shrunk film.
  • FIG. 1 shows a film 1 moving between a set of rollers 2 and 3 .
  • Adjustable blade 7 on pivot 6 is lowered to cut a slit in the film.
  • the location and the length of the slit is formed so that when a bundle of articles are film wrapped the slit 4 is located on the vertical sides of the bundle.
  • FIG. 2 shows three vertical slits 4 and three vertical slits 5 to be located on opposing vertical sides of the bundle.
  • After film wrapping the bundle moves through a heat shrink tunnel on a conveyor where the film is heat shrunk. Within in the tunnel, the slits are opened by increasing the shrinkage of the film surrounding the slit. This can be accomplished by directing high speed jets of hot air on the slits. Openings in excess of 20-25 mm can be achieved.
  • FIG. 3 shows cups of yogurt 7 having opened slits using jets of hot air.
  • the wrapped article is transported to a freezer or cooler 7 to prevent spoilage of the contents within the bundle.
  • the heat shrunk bundle can be bundled or palletized prior to entering the freezer or cooler.
