Abstract

Un conteneur bon marché à multifonction (125) possède une structure (127) de matériau composite ou de carton tubulaire en spirale ou en volute, pouvant avoir différentes formes géométriques afin de renfermer un récipient à paroi mince (131) à base d'un matériau formant une barrière pour renfermer et protéger un produit, l'épaisseur et la rigidité de la structure étant suffisantes pour soutenir et protéger au moins les côtés renfermés ainsi que le fond du récipient. L'épaisseur de la paroi en matériau du récipient ne permet pas au récipient de servir tout seul conventionnellement de conteneur pour le produit. Une fermeture (133) à l'extrémité supérieure du récipient assure l'étanchéité du produit de manière hermétique ou atmosphérique, le produit étant protégé de l'air, des autres gaz, de l'humidité et de la lumière. Le récipient peut être formé in situ à l'intérieur de la structure.
