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 and outer caps which are separated from one another and contain aligned openings which the fitment passes through. The caps also have projecting flaps which fit between the shell pieces. A fitment lock, which immovably engages the fitment, fits between the inner and outer caps and is adhesively affixed to at least one of them. The fitment lock and the caps 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 outer cap expose portions of the shell side wall between the inner and outer caps which can be engaged by the beak of an implement handling apparatus.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
106 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) an outer cap which covers said top end, said outer cap having at least one access opening defined therein adjacent to said side wall of said shell; wherein (e) said inner cap is sufficiently offset from said outer cap so that a drum handling implement can be inserted through said opening and engage said side wall.
Claim 2
Dependent Claim
106 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) an outer cap which covers said top end, said outer cap having at least one access opening defined therein adjacent to said side wall of said shell; wherein (e) said inner cap is sufficiently offset from said outer cap so that a drum handling implement can be inserted through said opening and engage said side wall.
Claim 3
Dependent Claim
111 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 inner and outer caps having aligned passageways defined therein which allow said fitment to open out of said container; and (d) a fitment lock, located between said inner and outer caps, 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 4
Dependent Claim
15 words
The container of claim 2 wherein said fitment lock bridges said inner and outer caps.
Claim 5
Dependent Claim
16 words
