lNVENTOR. L. R. EADES BY /"y A 7' TORNE VS 3,044,515 SELF-ERECTNG CGLLAPSIBLE CQNTAINERS Lawrence R. Eades, Berger, Tern, assignor to Phillips Petroleum (Jompany, a corporation of Deiaware Filed Apr. 27, 1959, Ser. No. 809,169 4 Claims. {CL 150-1) This invention relates to collapsible containers and particularly to collapsible containers of large size. In one aspect this invention relates to a method and a means for expanding or erecting a large collapsible container without increasing the pressure in the interior of the chamber above the ambient pressure. In another aspect the invention relates to a large collapsible container which can be filled with a finely divided solid material without necessity of inflating the interior of the container.
Large collapsible containers made of rubber or fabric are used for shipment of bulk materials. These containers can be cylindrical or cubical in shape and are usually lifted by means of cables or chains which encircle the bottom of the container so as to distribute the load upon lifting a filled container. The empty containers are usually returned to the point of origin and reused. These containers display particular utility for the transportation of carbon black, particularly pelleted carbon black, and are used Where carbon black is to be transported by railway car, barge or by truck. One particular disadvantage in the use of such containers is the difficulties encountered in filling the containers with bulk material, particularly particulate material of low density such as loose carbon black. The containers collapse under their own weight and when an empty container is lifted by the lifting cables, the sides collapse upon each other and the density of a material such as carbon black is not sufliciently great to force the sides apart; consequently, it is necessary to inflate the containers with gas pressure and to pump the particulate material into the container against the inflating gas pressure. This difficulty has limited the use of such containers for the shipment and transportation of pelleted carbon black and has substantially eliminated any consideration of utilizing such containers for the transportation of loose carbon black.
It is therefore a principal objectof this invention to provide a self-erecting, collapsible container. It is also an object of this invention to provide a method for filling a collapsible container with bulk material without the necessity of inflating the interior of the container. Another object of this invention is in the provision of a collapsible container having compartmented walls Which can be inflated so as to cause the container to assume an erect position. A further object of this invention is the provision of a collapsible carbon black container which can be filled with carbon black at ambient pressure. Other advantages and features of this invention will become apparent to one skilled in the art upon studying this disclosure including the appended drawing wherein:
FIGURE 1 is a view, partly in cross section, of a container constructed according to my invention.
FIGURE 2 is a modification of the invention.
FIGURE 3 is a plan view, partly in section, of the modification of the invention of "FIGURE 2.
FIGURE 4 is a modification of the container of =FIG- United States Patent assists Patented July 17, 1962 be inflated with air .or other gas so as to provide a degree of rigidity to the container walls suflicient to maintain the container in an erect position even when empty. The double wall construction also provides an additional measure of protection to the particulate material being carriedinsofar as two walls would require rupturing before leakage or contamination of the materials occurred. A container of about 400 cubic feet of space will accommodate about 3 to 4 tons of carbon black.
Referring now to the drawing, and particularly to FIG- URE 1, there is shown a container 9 constructed with an outer wall 10,- an inner wall 11, and containing a reinforcing cord 12 secured in the annulus between walls 10 and 11 to provide reinforcement for the structure. The reinforcing cordlZ is shown as a spiral encircling the walls of the container; however, such reinforcing cord could also be a plurality of horizontal or vertical cords or ribs encircling the container. If a plurality of cords are employed, so that a plurality of chambers are formed, the cords should be discontinuous so as to provide com munication among the chambers. The annulus between the walls It) and 11 can be filled with gas or emptied of gas through valve 13, which can be a conventional valve such as those used for the inflation of automobile tires or rubber life rafts. The material inlet 14 is a flange connection which is secured to walls 10 and 11 of contain'er 9 so as to form a closable opening therethrough. The material discharge 15 is a flanged connection similar to material inlet 14. Sealing ring 25 can be threaded onto the neck of the flange 14 so as to provide a. tight seal with the walls 10 and 11 of the container 9 or ring 25 can be bolted to the flange 14 or otherwise secured to flange 14.
A lifting eye 16 can be secured to the top of the container by clamps 17 and 18 which can be tightened upon the fabric walls 10 and 11 of the container by means of threads on the shaft of lifting eye 16, or by other means. Additional support can be supplied to the bottom of the container by means of cables 19 which are secured to the bottom of the container and to the clamp member 17.
Referring now to FIGURE 2, container 20 is similar to container. 9 except that instead of double wall construction, as in container 9, container20 has therein a plurality of air chambers indicated as 21. containing therein reinforcing ribs 22 and connected together by tubes indicated at 23. Perforations 24 in the reinforcing ribs 22 allow passage of gas so that all of the inflatable chambers indicated as 21 are interconnected and can be filled by a common valve. Inflating valve 13a, material inlet 14a and material discharge 15a can be the same as those of container 9 of FIGURE 1.
The reinforcing cord 12 of FIGURE 1 and the reinforcing ribs 22 of FIGURE 2 prevent ballooning of the inflated air space and provide added rigidity to the container when the inflatable compartments are inflated with a gas.
The self-erecting, collapsible containers of this invention can be constructed of any impervious, pliable material such as rubber, rubber impregnated fabric, or flexible synthetic materials such as polyethylene film, polyvinylchloride film, and the like. The reinforcing cord 12 of FIGURE 1 will preferably be made of material similar to that of the container so that the cord can be secured to the walls 10 and 11 by welding or by vulcanization. The cord 12 should be continuous so as to provide a continuous air chamber between wall 10 and wall 11 or means provided for communication among the various chambers if a plurality of cords are employed which result in a plurality of air chambers.
The self-erecting, collapsible containers of this inven tion are preferably made of nylon fabric impregnated with synthetic rubber such as a polymer of 2-chloro-1,3
' tional loading equipment, in most cases.
butadiene available from Du 'Pont Company under the name of neoprene; isobutylene containing a small amount of isoprene and known as butyl rubber; chloro sulfonated polyethylene available from Du Pont Company underthe name of Hypalon; and other synthetic rubbers having characteristics similar to those named. These synthetic rubbers are resistant to weather checking,
abrasion, and ozone attack and fabrics impregnated with suchjsynthetic rubbers can be repeatedly flexed without permanently bending the fibers of the fabric: Y
The containers of this invention can be caused to assume an erect position by inflating the inflatable compartment and the pressure required; will be determined by the size and weight of the container and the cross sectional area of the inflatable compartment therein. The required pressure will usually be from. about 2 to about 10 pounds per square inch. When in an erect position, the container can be filled bymerely pouring the bulk material into the container and the requirement for pumping the material or forcing the material into the container by pressure is eliminated. It is a feature of my invention that the containers can be utilized without addi can be inflated inplace in a railroad gondola car or truck and'gravity loaded, using existing hopper car facilities. The unloading operation can be similarly simplified. The collapsible ieature'allows the pressurized compartments or double wall to be deflated either after loading or after unloading. V
Reasonable variations and modificationsare possible within the scope of this disclosure without departing from the spirit and scope of the invention.
