Claims30
A molded article for providing a container, the molded article comprising:
- a body configurable to define a storage vessel of the container;
- the body is formed from a first thermoplastic that is stable in contact with water and from a second thermoplastic that is unstable in contact with water;
- wherein the second thermoplastic carries an additive therein;
- wherein the additive comprises a visual indicator configured to provide a visual indication responsive to one or more of stress induced strain of the body beyond a predetermined limit and temperature change of the body;
- and
- wherein the visual indicator is further configured to provide a prominent change in appearance upon a selected dimension of the container having crept beyond a pre-determined bound with dissolution or degradation of the second thermoplastic.
