- 14. A package according to claim 1 or claim 5, wherein the outer container has a translucent foot so as to allow a user to see if leakage of liquid from the sealed envelope has occurred.
- 15. A package according to claim 1 or claim 5, wherein a foot of the container has a trough to collect any liquid which may leak from the sealed envelope.
- 16. A package according to claim 1 or claim 5, wherein the outer container further comprises a shock absorbing base.
- 17. A package according to claim 1 or claim 5, wherein the outer container is semirigid.
- 18. A package according to claim 1 or claim 5, wherein a side wall of the outer container can flex and absorb shock loads.
- 19. A package according to claim 1 or claim 5, wherein the material from which the outer container is made has a degree of flexibility sufficient to help to absorb shocks or blows to the package.
- 20. A package according to claim 1 or claim 5, wherein the sealed envelope can flex under stress into a space in a bottom portion of the outer container so as to absorb shock.
- 21. A package according to claim 1 or claim 5, wherein the wall of the outer container is tapered downwardly towards the base.
- 22. A package according to claim 1 or claim 5, wherein the container has a substantially square or rectangular cross section with rounded corners or sides.
- 23. A package according to claim 1 or claim 5, wherein the volume of liquid in the sealed envelope is 0.25 to 3 liters.
- 24. A package according to claim 23, wherein the envelope is supported by walls of the container against downward movement.
- 25. A package according to claim 1 or claim 5, wherein the volume of liquid in the sealed envelope is 0.5 to 2 liters.
- 26. A package according to claim 1 or claim 5, wherein the sealed envelope material comprises a polyvinyl alcohol.
