Claims40
A rigid narrow-necked plastic bottle having laminated walls, the laminated walls comprising:
- a. a fluid-barrier lamina of a flexible non-frangible material which is highly impermeable to fluids, and
- b. a load-bearing lamina of a frangible plastic material which will delaminate from said fluid barrier lamina when said bottle is crushed.
A rigid blow molded plastic container having laminated walls, the laminated walls comprising:
- a. a fluid-barrier lamina of a flexible non-frangible material which is highly impermeable to fluids, and
- b. a load-bearing lamina of a frangible plastic material which will delaminate from said fluid-barrier lamina when said container is crushed.
A rigid injection blow molded plastic container havng laminated walls, the laminated walls comprising:
- a. a fluid-barrier lamina of a flexible non-frangible material which is highly impermeable to fluids, and
- b. a load-bearing lamina of a frangible plastic material which will delaminate from said fluid-barrier lamina when said container is crushed.
A rigid injection molded plastic container having laminated walls, the laminated walls comprising:
- a. a fluid-barrier lamina of a flexible non-frangible material which is highly impermeable to fluids, and
- b. a load-bearing lamina of a frangible plastic material which will delaminate from said fluid-barrier when said container is crushed.
