Patent

CA 2116189

ABSTRACT The invention is a package including a bundle of shirred casing sticks disposed and held together by a container which completely encloses the bundle. The container is formed insitu about the bundle from a heat shrink film which stiffens on heat shrinking to provide a self-supporting container conforming in shape generally to the bundle shape. During heat shrinking, portions of the film are insulated to prevent welding of these portions so they provide flaps which open to permit removal or replacement of sticks.

mballage renfermant un faisceau de baguettes revêtues d'une enveloppe élastique, regroupées et maintenues ensemble dans une enveloppe qui entoure entièrement le faisceau. Cette enveloppe est formée sur place autour du faisceau grâce à une pellicule thermorétractable qui acquiert une certaine rigidité en se rétractant sous l'effet de la chaleur et qui produit ainsi une enveloppe rigide dont la forme est bien adaptée à celle du faisceau. Lors de la phase de rétrécissement thermique, certaines parties de la pellicule sont préservées de la chaleur pour empêcher leur fusion, ce qui permet d'obtenir des volets que l'on peut ouvrir pour retirer ou remplacer des baguettes.
