Abstract
A disposable sterile plastic bag is proposed for holding samples in blenders during the mixing thereof comprises a two-ply sheet flexible material integrally joined at opposed side edges thereof and joined at the upper and lower ends thereof respectively by upper and lower heat seals with a sealed sample receiving chamber being defined between the two plastic sheets inwardly of the bag's side edges and upper and lower seals. Inwardly of the upper seal, there is defined a tear off line transversally across the two sheets and parallelly to the upper seal thereby forming a detachable strip outwardly of the tear off line. When the sample is ready to be introduced in the bag, the strip is removed from the bag by pulling it so as to cause rupture of the two sheets at the tear off line. The bag's chamber is thus sterile when the sample is introduced therein and the bag and its contents can then be inserted in the blender. The bag's sterility does not depend on how the bag is package or on the integrity of the packaging's seal as the bag is itself sterile until the strip is removed therefrom, that is until the bag is ready to be used.
