A METHOD OF HANDLING SUBSTANCES AND A CONTAINER FOR SUCH SUBSTANCES

摘要

A blow-thermoformed container (1) has a peripheral weld fin (3) encircling and joining two symmetrical shells (4) defining between them a hollow interior (5), a lower zone (5b) of which is partly filled with a liquid (2). The interior (5) has an upper zone (5a) and a narrowed intermediate zone (5c). The weld fin (3) also has a narrowed intermediate zone (3c) between its upper and lower zoens (3a and 3b). The intermediate zone (1c) is weaker than each of the upper zone (1a) and the lower zone (1b), so that the upper zone (1a) may be manually folded down about the intermediate zone (1c). Across the upper zone (1a) may be formed a line of weakness (6) to facilitate severing of the top of the container (1) from the remainder of the container (1) to expose the top of the hollow interior (5).
