Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
160 words
A liner for positioning within a conventional freight container having walls defining an opening normally closed by door means, and adapted for receiving, transporting and discharging bulk cargo comprising: an elongated, lightweight, flexible, bag member having at least one open end and having a configuration conforming generally to the interior length and width of a freight container; lightweight, flexible bulkhead means adjacent at least the open end of said elongated, flexible bag member; said flexible bulkhead means being yieldable to transmit forces applied by bulk cargo within the liner directly to the container door means; means retaining a substantial portion of said elongated bag to said yieldable bulkhead means for substantially closing said flexible bag member, said yieldable bulkhead means defining first opening means for loading bulk cargo and second opening means spaced from said first opening means for unloading bulk cargo; and means normally sealing said second opening means until bulk cargo is to be unloaded from the liner.
Claim 2
Dependent Claim
160 words
A liner for positioning within a conventional freight container having walls defining an opening normally closed by door means, and adapted for receiving, transporting and discharging bulk cargo comprising: an elongated, lightweight, flexible, bag member having at least one open end and having a configuration conforming generally to the interior length and width of a freight container; lightweight, flexible bulkhead means adjacent at least the open end of said elongated, flexible bag member; said flexible bulkhead means being yieldable to transmit forces applied by bulk cargo within the liner directly to the container door means; means retaining a substantial portion of said elongated bag to said yieldable bulkhead means for substantially closing said flexible bag member, said yieldable bulkhead means defining first opening means for loading bulk cargo and second opening means spaced from said first opening means for unloading bulk cargo; and means normally sealing said second opening means until bulk cargo is to be unloaded from the liner.
Claim 3
Dependent Claim

Claim 5
Dependent Claim
26 words
A container liner for transporting bulk cargo as defined in claim 1, wherein said bulkhead means includes means for retaining the bulkhead in an upright position.
Claim 6
Dependent Claim
37 words
A container liner for transporting bulk cargo as defined in claim 1, wherein said first opening means includes an opening for loading bulk cargo into the liner and an opening for venting the liner to the atmosphere.
Claim 7
Dependent Claim
27 words
A container liner for transporting bulk cargo as defined in claim 1 wherein the flexible bag is tubular and both ends are closed by yieldable bulkhead means.
Claim 8
Dependent Claim
115 words
A transportable liner package adapted to be positioned within a conventional freight container for receiving, transporting and discharging bulk cargo comprising: at least one lightweight, flexible, bulkhead means, said flexible bulkhead means defining spaced first and second opening means for loading and unloading bulk cargo, means sealing at least said bulk cargo unloading opening means, an elongated, lightweight, flexible bag member having at least one open end, said elongated bag member being folded in a collapsed condition and contiguous with said bulkhead means; means securing said bulkhead means to said bag member at said open end; and means encompassing said bulkhead means and said bag member for retaining said liner in a collapsed, transportable package.
Claim 9
Dependent Claim
115 words
A transportable liner package adapted to be positioned within a conventional freight container for receiving, transporting and discharging bulk cargo comprising: at least one lightweight, flexible, bulkhead means, said flexible bulkhead means defining spaced first and second opening means for loading and unloading bulk cargo, means sealing at least said bulk cargo unloading opening means, an elongated, lightweight, flexible bag member having at least one open end, said elongated bag member being folded in a collapsed condition and contiguous with said bulkhead means; means securing said bulkhead means to said bag member at said open end; and means encompassing said bulkhead means and said bag member for retaining said liner in a collapsed, transportable package.
Claim 10
Dependent Claim
49 words
A transportable liner package as defined in claim 7, wherein said bulkhead is secured within an open end of said bag member, said bulkhead defining openings therein for facilitating loading and unloading of bulk cargo, and said member including portions which overlap and seal the openings in said bulkhead.
Claim 11
Dependent Claim
40 words
A transportable liner package as defined in claim 7, said flexible bulkhead means including spaced lip portions extending generally at right angles relative to said wAll portion, said lip portions encompassing at least a portion of said collapsed bag member.
Claim 12
Dependent Claim
24 words
A transportable liner package as defined in claim 7, wherein a flexible bulkhead means is secured to each end of said flexible, collapsed bag.
Claim 13
Dependent Claim
50 words
A transportable liner package as defined in claim 10, wherein each bulkhead means includes a wall portion and spaced lip portions extending at right angles relative to said wall portions, the lip portions of said bulkheads being in substantially abutting relation for encompassing the bag member collapsed between the bulkheads.
Claim 14
Dependent Claim
122 words
Apparatus for transporting bulk cargo comprising a container having side walls, an end wall, a bottom and a rear opening normally closed by at least one door, disposable, lightweight liner means positioned within said container for receiving the bulk cargo including a flexible, hollow bag having at least one open end and means for closing said open end, means for releasably positioning said liner between said container side walls for maintaining said liner in an opened condition, said closure means comprising a flexible, lightweight bulkhead positioned adjacent the container door opening such that forces applied by the bulk cargo within the liner will be transmitted to the bulkhead which yields and engages the door to apply forces directly to the container door.
Claim 15
Dependent Claim
122 words
Apparatus for transporting bulk cargo comprising a container having side walls, an end wall, a bottom and a rear opening normally closed by at least one door, disposable, lightweight liner means positioned within said container for receiving the bulk cargo including a flexible, hollow bag having at least one open end and means for closing said open end, means for releasably positioning said liner between said container side walls for maintaining said liner in an opened condition, said closure means comprising a flexible, lightweight bulkhead positioned adjacent the container door opening such that forces applied by the bulk cargo within the liner will be transmitted to the bulkhead which yields and engages the door to apply forces directly to the container door.
Claim 16
Dependent Claim
