Tray for stacking layers of structural bottles

A tray for stacking layers of structural bottles comprising:

• a web of material having an upper surface and an opposed lower surface, the upper surface has a plurality of wells disposed in an array of columns and rows, the lower surface has a plurality of pockets disposed in an array of columns and rows, each pocket having a complementary shape to a corresponding well, each well has an annular seating surface circumjacent a post and separated therefrom by an annular recess, the annular seating surface being segmented with each segment having a generally concave surface facing radially inwardly of the well, the concave surface having a vertical portion that extends downwardly and radially inwardly to a radial segment, the radial segment forms a horizontal support surface for receiving a bottom of one of the structural bottles, and a first rectangular shaped notch in one of the segments for receiving an edge of one of the structural bottles.

A stacking arrangement for structural bottles comprising:

• a tray of a web of material having an upper surface and an opposed lower surface, the upper surface has a plurality of wells disposed in an array of columns and rows, the lower surface has a plurality of pockets disposed in an array of columns and rows, each pocket having a complementary shape to a corresponding well, each well has an annular seating surface circumjacent a cylindrical post and separated therefrom by an annular recess, the annular seating surface being segmented with each segment having a generally concave surface facing radially inwardly of the well, the concave surface having a vertical portion that extends downwardly and radially inwardly to a radial segment, the radial segment forms a horizontal support surface for receiving a bottom of one of the structural bottles, and a first rotational interlock structure extending outward from the concave surface along one of the segments;
• and
• a structural bottle having a bottom surface, a sidewall and a handle, the bottom surface in the well and the first rotational interlock structure engaging a portion of the bottle to resist rotation about an axis of the well.
