Abstract
Abstract A container is provided for large quantities of fluent material and comprises laminated walls, each of which is made of multi-wall corrugated board. A bag of flexible material is provided within the container and has a first fitting which extends into an opening through a wall of the container near the bottom; a flap covers the opening and conceals the fitting being held in position by a severable strap. The container has bottom-forming flaps extending from the intermediate one of three layers forming the container to form a bottom for the container. The discharge fitting is secured to a flap which extends from a bottom plate extending through an opening in the flap and having flanges on either side of the flap, there being a tab partially cut from the flap with a free edge adjacent the opening, so that the fitting may be inserted through the opening formed by the tab and then slid into position in the small opening with the flanges on either side of the flap and being held in position by restoration of the tab to its normal position. An assembly is provided which includes a top plate, a bottom plate and a bag, with the bag secured to the top and bottom plates, preferably by the locking of a fitting to each of the plates. There is also provided a flattened container having steel bands on it in the flattened condition.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
121 words
A container for large quantities of fluent material comprising: a plurality of serially connected panels having bottom edges, each of said panels being in angular relationship to an adjacent panel to thereby form an encompassing wall, the panels of said wall each comprising a plurality of layers of multi-wall corrugated board including an outer layer and a layer inwardly of said outer layer, the panels of said last mentioned layer each having a flap extending from the bottom edge thereof, each of said flaps being of generally trapezoidal shape and extending from and connected to the lower edge of a said panel at a fold line, said trapezoidal flaps extending inwardly of said wall and forming the bottom of said container.
Claim 2
Dependent Claim
121 words
A container for large quantities of fluent material comprising: a plurality of serially connected panels having bottom edges, each of said panels being in angular relationship to an adjacent panel to thereby form an encompassing wall, the panels of said wall each comprising a plurality of layers of multi-wall corrugated board including an outer layer and a layer inwardly of said outer layer, the panels of said last mentioned layer each having a flap extending from the bottom edge thereof, each of said flaps being of generally trapezoidal shape and extending from and connected to the lower edge of a said panel at a fold line, said trapezoidal flaps extending inwardly of said wall and forming the bottom of said container.
Claim 3
Dependent Claim
47 words
The container of claim 1, wherein the panels of said wall each comprise three layers of multi-wall corrugated board, said flaps extending from the intermediate of said three layers, and said inner layer comprising panels having bottom edges which adjoin the upper surfaces of said trapezoidal flaps.
Claim 4
Dependent Claim
15 words
The container of claim 2 wherein the inner two layers are of triple-wall corrugated board.
Claim 5
Dependent Claim
47 words
The container of claim 1, said container comprising three layers of multi-wall corrugated board, the lower edges of the panels of said outer layer having a flap foldably connected thereto, said flaps each being adjacent the outer surface of the panel to which it is foldably connected.
Claim 6
Dependent Claim
88 words
A structure for producing a container comprising: a blank comprising a plurality of panels in serial array connected together at adjacent foldlines, said structure including end panels, means joining the end panels together to form a continuous wall structure, said wall structure being in flat condition with each panel being in facing, substantially engaging relationship with another panel of said blank, and at least one band encircling said flattened continuous wall structure. said band being of material strong in tension and tightly encircling said flattened continuous wall structure.
Claim 7
Dependent Claim
88 words
A structure for producing a container comprising: a blank comprising a plurality of panels in serial array connected together at adjacent foldlines, said structure including end panels, means joining the end panels together to form a continuous wall structure, said wall structure being in flat condition with each panel being in facing, substantially engaging relationship with another panel of said blank, and at least one band encircling said flattened continuous wall structure. said band being of material strong in tension and tightly encircling said flattened continuous wall structure.
Claim 8
Dependent Claim
17 words
The structure of claim 5, wherein each of said panels is of multiple layers of corrugated paperboard.
Claim 9
Dependent Claim
145 words
A container for holding large quantities of fluent material comprising: at least two contiguous layers of multi-wall corrugated paperboard, each comprising panels in angular relation to adjacent panels and foldably connected thereto at fold lines between said panels, means for adhering together said two layers, the outermost of said two layers having flaps extending from the bottom edge thereof, each of said flaps being of generally trapezoidal shape and extending from and connected to the lower edge of a said panel at a fold line at the bottom thereof, said flaps extending inwardly and forming the bottom of said container, and a shell of multi-wall corrugated paperboard comprising panels in angular relation to adjacent panels and foldably connected thereto at fold lines, said panels of said shell being outwardly of and respectively contiguous with panels of the said outermost of said two first mentioned layers.
Claim 10
Dependent Claim
145 words
A container for holding large quantities of fluent material comprising: at least two contiguous layers of multi-wall corrugated paperboard, each comprising panels in angular relation to adjacent panels and foldably connected thereto at fold lines between said panels, means for adhering together said two layers, the outermost of said two layers having flaps extending from the bottom edge thereof, each of said flaps being of generally trapezoidal shape and extending from and connected to the lower edge of a said panel at a fold line at the bottom thereof, said flaps extending inwardly and forming the bottom of said container, and a shell of multi-wall corrugated paperboard comprising panels in angular relation to adjacent panels and foldably connected thereto at fold lines, said panels of said shell being outwardly of and respectively contiguous with panels of the said outermost of said two first mentioned layers.
Claim 11
Dependent Claim
21 words
The container of claim 10, and further comprising aligned openings in said two layers and said shell adjacent the bottoms thereof.
Claim 12
Dependent Claim
40 words
The container of claim 8, and a flap at and foldably connected to the bottom of each panel of said shell, each said last mentioned flap being adjacent the outer surface of the panel to which it is foldably connected.
Claim 13
Dependent Claim
40 words
The container of claim 7, and a flap at and foldably connected to the bottom of each panel of said shell, each said last mentioned flap being adjacent the outer surface of the panel to which it is foldably connected.
