Abstract

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.

Claims Analysis

Total Claims: 10

Claim 1

Independent Claim 157 words

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.

Claim 2

Dependent Claim 157 words

Claim 3

Dependent Claim 43 words

In the case of claim 1, a lower horizontal panel abutting the bottom edge of each sidewall and endwall and extending from end to end thereof, and respective horizontal outwardly projecting ribs along the upper and lower edges of each said lower panel.

Claim 4

Dependent Claim 40 words

In the case of claim 2, angular gusset plates formed at the juncture of said structural columns with said lower horizontal panel, each plate having an outwardly projecting rib along its angular edge merging with adjacent vertical and horizontal ribs.

Claim 5

Dependent Claim 18 words

In the case of claim 3, said gusset plates and structural columns defining polygonal openings in said sidewalls.

Claim 6

Dependent Claim 49 words

In the case of claim 3, each said endwall including a plurality of pairs of horizontal and vertical ribs defining an end and central vertical columnar structure and further defining a pair of vertically extending rectangular openings extending upwardly from said horizontal panel and terminating at an intermediate point.

Claim 7

Dependent Claim 46 words

In the case of claim 5, each endwall having a centrally disposed rectangular rib structure adjacent its upper edge defining a hand hole, an extension of each said central vertical columnar structure disposed through each said hand hole to the upper stacking rim of said case.

Claim 8

Dependent Claim 72 words

In the case of claim 6, a respective pair of inner vertical rib members disposed in the interior of said case adjacent and coextensive with each said structural column, the upper ends of said rib members curving into said upper stacking rim, and bearing block members disposed at the upper ends of the inner vertical rib members on said endwalls, said block members having rectangular flat upper surfaces coplanar with said rim.

Claim 9

Dependent Claim 38 words

In the case of claim 7, said bottom comprised of longitudinal and transverse ribs defining a rectangular lattice support network, a plurality of open center circular disc members disposed on said network to form inner bottom bottle supports.

Claim 10

Dependent Claim 27 words

In the case of claim 8, a plurality of spaced, downwardly projecting rectangular ribs on the outer bottom of said network to provide a stacking stabilizing structure.
