Abstract: An ampul for containing a physiologically acceptable liquid comprises a tubular body 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 has at least one end portion of reduced cross-sectional dimension formed with a peripheral line of weakness enabling the end portion to be manually fractured. The ampul 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.
