1 compression package 10 may be inverted momentarily to break the
2 tension and force of the folds 24.” (Lizio, col. 4, ll. 59-63).
3 14. “Because the tension and opposing force of the folds 24 has
4 been broken and relieved, the articles 22 will bloom and expand
5 upward into the now open coextensive communication with the
6 chamber 20 as shown in FIG 4.” (Lizio, col. 4, ll. 71-74).
7 15. Once again, it has been found that when the compression
8 package 10 is subjected to a sterilizing process, the heat and
9 moisture applied to the compressed articles 22 contained
10 therewithin causes such articles to bloom or expand rapidly
11 upward into the chamber 20. Because the tension of the folds
12 24 has been broken, the expanding articles 22 are no longer
13 restricted from blooming upward into the co-extensive
14 communicating expansion chamber portion 20. In order to
15 permit the adequate expansion or blooming of the articles 22
16 and to prevent the rupture or tearing of the walls of the
17 container 12 during the expansion of such articles, the
18 expansion chamber 20 is made of such size and shape that it
19 will have sufficient room to accommodate the fully expanded
20 articles without affecting the seals provided at the end 14 or the
21 edge 28.

23 (Lizio, col. 5, ll. 3-18).
24 16. When it is desired to permit the compressed articles 22 to
25 bloom or expand again to their normal condition, the
26 compression package 100 of FIG. 5 is positioned on any
27 convenient surface with its end 14 now serving as the bottom.
28 A restraining tear tab 42 secured in place over the fold rolled
29 zig-zag folded structure 36 of the expansion chamber portion 20
30 is manually pulled free. The fold 36 is manually lifted and
31 straightened until it assumes the position as shown in FIG. 3.
32 The fold lines 24 are pinched or the container 12 is shaken to
33 reduce the tension of such fold lines on the compressed articles
34 22. Thereater, the articles 22 are permitted to expand formally
