Bulk material container

Claim 2

A topcap for a bulk container, said topcap comprising: (a) a central panel; (b) a pair of opposed inner side panels hingedly attached to said central panel; (c) a pair of opposed outer side panels hingedly attached to their respective inner side panels; (d) a pair of opposed inner end panels hingedly attached to said central panel; (e) a pair of opposed outer end panels hingedly attached to their respective inner end panels; and (f) a plurality of gusset panels, each of said gusset panels being hingedly connected to an inner side panel and an inner end panel, each of said gusset panels containing a diagonal score line extending from an innermost corner adjacent the central panel to an outer corner of said gusset panel, each of said gusset panels serving to provide a leak proof corner to the topcap; each of said gusset panels further having a cutout portion along the area defined by said diagonal score line, said cutout portion serving as a retention area for positioning a banding strap and securing the topcap to the bulk material container.

Claim 3

A combination bulk material container comprising: (a) an exterior body having a series of hingedly connected wall panels, each wall panel having hingedly connected thereto on opposed ends a top flap and a bottom flap, one of said wall panels having a hingedly connected adjoining flap for securing the panels together; (b) an interior body formed from a first inner liner and a second outer liner laminated together; (i) said first inner liner being formed from a series of hingedly connected wall panels, one of said wall panels having a glue panel hingedly connected thereto for securing the wall panels together; (ii) said second outer liner being formed from a series of hingedly connected wall panels, one of said wall panels having a glue flap hingedly connected thereto for securing said panels together; (iii) each of said wall panels of said second outer liner having hingedly connected thereto on opposed ends a top flap and a bottom flap; (c) stress reduction means formed in said interior body, said stress reduction means comprising; (i) a first manufacturing joint formed in the first inner liner of the interior body by the glue panel on said inner liner overlapping and being secured against an adjacent wall panel; (ii) a second manufacturing joint formed in the second outer liner of the interior body by the glue flap on said second outer liner overlapping and being secured to an adjacent wall panel on the second outer liner; (iii) said first and second manufacturing joints being offset from each other a predetermined distance thereby providing a triple thickness along a portion of one of the walls of the interior body; (d) separation means, associated with said exterior and interior bodies, for providing an opening between said exterior and interior bodies to provide additional protection for the products packaged within said interior body; (e) a topcap, associated with the top of the exterior body and comprising: (i) a central panel; (ii) a pair of opposed inner side panels hingedly attached to said central panel; (iii) a pair of opposed outer side panels hingedly attached to their respective inner side panels; (iv) a pair of opposed inner end panels hingedly attached to said central panel; (v) a pair of opposed outer end panels hingedly attached to their respective inner end panels; (vi) a plurality of gusset panels, each of said gusset panels being hingedly connected to an inner side panel and an inner end panel, each of said gusset panels containing a diagonal score line extending from an innermost corner adjacent the central panel to an outer corner of said gusset panel, each of said gusset panels serving to provide a leak proof corner to the topcap; the gusset panels further having a cutout portion along the area defined by said diagonal score line, said cutout portion serving as a retention area for positioning a banding strap and securing the topcap to the bulk material container; and (f) a banding strap positioned around the topcap and over the retention area to tightly band the topcap to the exterior body.

Claim 4

A combination bulk material container comprising: (a) an exterior body having a series of hingedly connected wall panels, each wall panel having hingedly connected thereto on opposed ends a top flap and a bottom flap, one of said wall panels having a hingedly connected adjoining flap for securing the panels together; (b) an interior body formed from a first inner liner and a second outer liner laminated together; (i) said first inner liner being formed from a series of hingedly connected wall panels, one of said wall panels having a glue panel hingedly connected thereto for securing the wall panels together; (ii) said second outer liner being formed from a series of hingedly connected wall panels, one of said wall panels having a glue flap hingedly connected thereto for securing said panels together; (iii) each of said wall panels of said second outer liner having hingedly connected thereto on opposed ends a top flap and a bottom flap; (c) stress reduction means formed in said interior body, said stress reduction means comprising; (i) a first manufacturing joint formed in the first inner liner of the interior body by the glue panel on said inner liner overlapping and being secured against an adjacent wall panel; (ii) a second manufacturing joint formed in the second outer liner of the interior body by the glue flap on said second outer liner overlapping and being secured to an adjacent wall panel on the second outer liner; (iii) said first and second manufacturing joints being offset from each other a predetermined distance thereby providing a triple thickness along a portion of one of the walls of the interior body; (d) separation means, associated with said exterior and interior bodies, for providing an opening between said exterior and interior bodies to provide additional protection for the products packaged within said interior body; (e) a topcap, associated with the top of the exterior body and comprising: (i) a central panel; (ii) a pair of opposed inner side panels hingedly attached to said central panel; (iii) a pair of opposed outer side panels hingedly attached to their respective inner side panels; (iv) a pair of opposed inner end panels hingedly attached to said central panel; (v) a pair of opposed outer end panels hingedly attached to their respective inner end panels; (vi) a plurality of gusset panels, each of said gusset panels being hingedly connected to an inner side panel and an inner end panel, each of said gusset panels containing a diagonal score line extending from an innermost corner adjacent the central panel to an outer corner of said gusset panel, each of said gusset panels serving to provide a leak proof corner to the topcap; the gusset panels further having a cutout portion along the area defined by said diagonal score line, said cutout portion serving as a retention area for positioning a banding strap and securing the topcap to the bulk material container; and (f) a banding strap positioned around the topcap and over the retention area to tightly band the topcap to the exterior body.
