Abstract (en)
A container (10) has a movable end closure (18) for accommodating expansion or contraction of the product (8) packaged therein. The container includes a hollow body portion (12) with opposed open ends (13) and an inside surface (14) and an end closure positioned at each of the open ends of the hollow body portion (12). One of the end closures (18) is of a generally outwardly-facing cup-shaped configuration positioned inside the hollow body portion (12) and has a radially-extending central portion (21) of generally the same configuration and dimensions as the inside surface (14) of the body portion and an accordion-folded sidewall (22) extending axially from the central portion toward the body portion open end (13) to define a free end area (23) secured to the inside surface of the body portion at the open end (13). The central portion (21) may axially move along the body portion inside surface (14) toward or away from the body portion open end (13) by contraction or expansion of the end closure accordion-folded side wall (22) to increase or decrease the effective volume of space within the container. <IMAGE>
