<p>An ampul (10) for containing a physiologically acceptable liquid comprises a tubular body (12) made of a non-toxic, chemically inert thermoplastic material having an elongation at break ranging from about 100 % to about 200 %, a tensile strength at break less than about 15,000 psi and a flexural modulus less than about 400,000 psi. The tubular body (10) has at least one end portion (20) of reduced cross-sectional dimension formed with a peripheral line of weakness (24) enabling the end portion (20) to be manually fractured. The ampul (10) according to the invention is impact-resistant and forms a clean cut when the end portion is fractured to dispense its content, thereby eliminating dangerous shards.</p> |
