A partition for a packaging box having a bottom, two opposing sides, and two opposing ends. The partition includes four panels. The first panel is located between and substantially parallel to the ends, between and substantially perpendicular to the sides, and substantially perpendicular to the bottom. The second panel is joined to the box and joined to the first panel along a first fold line. The third panel is located immediately adjacent the first panel. The fourth panel is joined to the third panel along a second fold line that is substantially perpendicular to the first fold line.

A pressure-activated valve for use with a container for dispensing fluid material, the valve comprising: an outer component comprising a nozzle, the nozzle comprising a substantially cylindrical sidewall having a top edge and an annular flexible portion extending radially inward from the top edge of the sidewall and terminating in a rigid annular rim, the nozzle sidewall comprising a substantially cylindrical expansible portion, the annular flexible portion being configured to flex upward and outward and the expansible portion being configured to expand when each is subjected to sufficient pressure from the container fluid material, thereby moving the rim in an axial direction from a closed position to an open position; and an inner component comprising a sidewall and a convex stationary sealing portion connected to the inner component sidewall via bridges, the inner component being affixed to the nozzle cylindrical sidewall to mate closely therewith, the sealing portion and the rim cooperating to form a seal when the rim is in the closed position, the sealing portion and annular rim defining an annular opening when the annular rim is in the open position. 10. A pressure-activated valve for use with a container for dispensing fluid material, the valve comprising: a first component comprising a covering portion for covering an end of the container and having a centrally disposed aperture, a cylindrical sidewall extending axially downward from the periphery of the covering portion, a neck portion extending axially upward from the periphery of the aperture, and a stationary sealing portion connected to the neck by bridges; and a substantially cup-shaped second component mounted over the first component neck and comprising an axially oriented sidewall having a top edge and a flexible annular top portion extending radially inward from the top edge and terminating in a moveable rim, the flexible portion being configured to flex upward and outward when subjected to a predetermined amount of pressure from the container fluid material, thereby moving the rim from a closed position to an open position, the rim and the sealing portion cooperating to form a seal when the rim is in the closed position, the rim and the sealing portion defining an annular opening through which fluid may flow when the rim is in the open position.
