Abstract
Abstract An improved means and method for shipping industrial sized quantities of hazardous concentrates which simplifies compliance with current environmental protection regulations. The method includes the steps of loading a collapsible shipping container with a collapsible bag which is partially filled with a liquid or particulate concentrate of a potentially hazardous material, collapsing the bag before inserting it into the shipping container. The container itself is then collapsed, sealed and shipped to the user. Upon arrival, the user erects the container, unfolds and fills the bag with a solvent such as water to fill the container and serve as a storage facility. The diluted or dissolved product is then drawn from the container as required until the container is empty. The user then collapses the bag and the container for return to the sender. As a result, no permanently installed storage facility need be cleaned. The container is configured to form a generally planar storage well at a lower end thereof to store the bag and a reinforcing tray may be provided to enclose the collapsed bag.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
192 words
A method for the shipping of hazardous concentrates in liquid and particulate forms comprising the steps of: a) providing a collapsible shipping container defining a non-collapsible generally rectangularly shaped well at a lower end thereof, said container having a collapsible impervious bag of dimensions corresponding to the interior of said container when in erected condition; b) Partially filling and sealing said bag with a concentrate to a degree permitting said bag in subsequently folded condition to be store within said well; c) Positioning said partially filled bag within said well; d) collapsing said container to enclose said well; e) shipping said container to a user in collapsed condition; f) upon arrival to said user, erecting said container and bag and filling the remaining volume of said bag with a diluent or solvent to dilute or dissolve said concentrate to a desired degree of concentration; g) employing said container and bag as a storage facility while draining required amounts of material therefrom; and h) upon the substantial emptying of said bag, collapsing said bag for reuse or discard, returning the same to storage in said well, and recollapsing said container for return shipment.
Claim 2
Independent Claim
192 words
A method for the shipping of hazardous concentrates in liquid and particulate forms comprising the steps of: a) providing a collapsible shipping container defining a non-collapsible generally rectangularly shaped well at a lower end thereof, said container having a collapsible impervious bag of dimensions corresponding to the interior of said container when in erected condition; b) Partially filling and sealing said bag with a concentrate to a degree permitting said bag in subsequently folded condition to be store within said well; c) Positioning said partially filled bag within said well; d) collapsing said container to enclose said well; e) shipping said container to a user in collapsed condition; f) upon arrival to said user, erecting said container and bag and filling the remaining volume of said bag with a diluent or solvent to dilute or dissolve said concentrate to a desired degree of concentration; g) employing said container and bag as a storage facility while draining required amounts of material therefrom; and h) upon the substantial emptying of said bag, collapsing said bag for reuse or discard, returning the same to storage in said well, and recollapsing said container for return shipment.
Claim 3
Dependent Claim
36 words
The method in accordance with claim 1 including the step of providing a hollow tray element and positioning the same within said well prior to placing said partially filled bag upon said tray for initial shipment.
Claim 4
Dependent Claim
44 words
The method in accordance with claim 1, including the step of providing a collapsible hollow tray element for holding said partially filled bag, and placing said tray element in erected condition in said well prior to positioning said partially filled bag therein for shipment.
Claim 5
Dependent Claim
87 words
An improved shipping container for the transportation of hazardous concentrates comprising: a generally rectangular outer element having a non-collapsible well at a lower end thereof, a bag receiving tray element of configuration corresponding to the interior of said well, said tray element having a bottom wall and a continuous side wall; and a collapsible generally impervious bag element capable of holding particulate and liquid concentrates, said bag element being only partially filled with such concentrate to a degree permitting the storage of the same within said well.
Claim 6
Dependent Claim
87 words
An improved shipping container for the transportation of hazardous concentrates comprising: a generally rectangular outer element having a non-collapsible well at a lower end thereof, a bag receiving tray element of configuration corresponding to the interior of said well, said tray element having a bottom wall and a continuous side wall; and a collapsible generally impervious bag element capable of holding particulate and liquid concentrates, said bag element being only partially filled with such concentrate to a degree permitting the storage of the same within said well.
Claim 7
Dependent Claim
20 words
An improved shipping container in accordance with claim 4, in which the tray element is collapsible to generally planar condition.
Claim 8
Dependent Claim
19 words
