Abstract
A heavy-duty plastic molded single-cell beverage case provided with a plurality of columnar support members extending from the upper stacking rim to the bottom of the case for transmitting and withstanding high compressive stacking forces, the support members defined by a ribbed structure. A plurality of horizontal ribs, an upper rectangular panel and triangular gusset plates disposed at the junction of the columnar members and said panel enhance the structual rigidity and strength of the case.
Claims9
A heavy-duty unitary plastic molded full-depth beverage case comprising pairs of side and endwalls and a bottom, the top of said case having an outwardly projecting stacking rim extending around the case, a similar lower rib member disposed adjacent said rim, an upper panel on each sidewall extending downwardly from said top and terminating in a lower edge at an intermediate point, a plurality of pairs of vertical ribs disposed along each panel from said rim to said lower edge, a pair of horizontal ribs disposed around said case adjacent said lower edge, alternate pairs of said vertical ribs extending from top to bottom of said case to define structural columns for transmitting compressive stresses through the case in a stacked configuration with other similar cases and angular gusset plates formed at the juncture of said structural columns with said panel, each plate having an outwardly projecting rib along its angular edge merging with adjacent vertical ribs.
