Abstract
A mechanical assembly for securing a first sheet to a second sheet includes a first projection having a first sidewall and a first top wall. The first sidewall extends from the first top wall at a first acute angle. The first sidewall includes a first top end and a first bottom end. A first discontinuity is defined in the first sidewall between the first top end and the first bottom end. A first base wall extends from the first bottom end. The first base wall extends generally parallel to the first top wall.

A first sheet configured for connection to a second sheet to define a pack assembly, the first sheet comprising:
- a series of peaks including a first peak with an upper surface and a series of valleys;
- a first projection extending from the upper surface of the first peak, the first projection having a first sidewall, a first internal space and a first top wall, the first sidewall extending from the first top wall away from the first internal space at a first acute angle, the first sidewall including a first top end and a first bottom end, a first discontinuity defined in the first sidewall between the first top end and the first bottom end, the first sidewall extending at a taper away from the first internal space between the first top end and the first discontinuity,
- the upper surface of the first peak extending from the first bottom end, generally parallel to the first top wall, the first sidewall extending away from the first internal space from the first top wall to the first discontinuity and away from the first internal space from the first discontinuity to the upper surface of the first peak as the first sidewall extends between the first top wall and the upper surface of the first peak, the first sidewall extending from the first bottom end at a second acute angle.
