Abstract
Abstract A paperboard container for storing and transporting fluids has a tubular shell formed from interfitting inner and outer shell pieces. The shell is enclosed at its bottom end by a base having projecting flaps which are sandwiched between the shell pieces and flaps located at the bottom of the outer shell cover the base. A flexible liner located in the shell has a fitment at its upper end which permits the liner to be filled and emptied. The top of the shell is covered with inner cap and a closure means which are separated from one another and contain aligned openings which the fitment passes through. A fitment lock, which immovably engages the fitment, fits between the inner cap and closure means and is adhesively affixed to at least one of them. The fitment lock, and the inner cap and closure means act in conjunction to prevent movement of the fitment and to provide the lateral and longitudinal stability necessary to permit a hand pump to be installed in the fitment. Openings located around the periphery of the closure means expose portions of the shell sidewall between the inner cap and closure means which can be engaged by the beak of an implement handling apparatus.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
103 words
A container for a fluid material comprising: (a) an upright tubular shell, having a sidewall, a top end and a bottom end; (b) means for closing said bottom end of said shell; (c) an inner cap which fits within said shell proximate said top end but downwardly offset therefrom; (d) closure means for covering said top end, said closure means having at least one access opening defined therein adjacent to said sidewall of said shell; wherein (e) said inner cap is sufficiently offset from said closure means so that a drum handling implement can be inserted through said opening and engage said sidewall.
Claim 2
Dependent Claim
103 words
A container for a fluid material comprising: (a) an upright tubular shell, having a sidewall, a top end and a bottom end; (b) means for closing said bottom end of said shell; (c) an inner cap which fits within said shell proximate said top end but downwardly offset therefrom; (d) closure means for covering said top end, said closure means having at least one access opening defined therein adjacent to said sidewall of said shell; wherein (e) said inner cap is sufficiently offset from said closure means so that a drum handling implement can be inserted through said opening and engage said sidewall.
Claim 3
Dependent Claim
37 words
The container of claim 1 wherein said closure means comprises a plurality of tabs which depend from the top end of said tubular shell, said tabs being foldable to overlap one another and cover said top end.
Claim 4
Dependent Claim
115 words
The container of claim 1 further comprising: (a) a flexible, impervious liner located within said shell between said inner cap and said bottom end; (b) a fitment on said liner for filling and emptying said liner with a fluid material, said fitment having a cylindrical passageway with a central axis; (c) said closure means and said inner cap having aligned passageways defined therein which allow said fitment to open out of said container; and (d) a fitment lock, located between said closure means and said inner cap, that engages said fitment, said fitment lock providing support for and preventing movement of said fitment parallel and transverse to said central axis when said fitment is loaded.
Claim 5
Dependent Claim
