Description
3~(3 BULR MATERIAL CONTAINER
The present invention pertains to bulk material containers and more particularly, to bulk material con-tainers fabricated from reinforced kraft paper or the like, for transporting and storing bulk materials having means for dispensing bulk material ~rom the bottom there-of.
Paper and paperboard containers are desirably used for transporting and storing materials due to their light weight and low cost as well as their capability of being stored in ~;n;m~l space in a compact, folded, knock-ed-down state. For transporting and storing bulk materials, however, the structure of the containers must be sufficiently strong to hold extremely large weights, often on the order of a ton. Due to the large size and weight of the bulk material placed in the container, it has also ~een found desirable to construct such containers to permit dispensing of the contents from the bottom, thereby obviating the necessity of tipping the containers to remove the contents.
v~
One such bulk material container is known as a sling bin and is manufactured by the St. Regis Paper Com-pany of Nyack, New York. A sling bin is a large open mouthed ba~ adapted to be shipped and stored flat, which 5 can be erected and filled with bulk material while sus-pended so that the total bin capacity can be utilized.
The bin is provided with opposed loops extending upwardly from opposed portions of the bag mouth which are folded back upon themselves and secured to the bag sidewalis to 10 form a paix of slings for suspending the bin from a pair of horizon',:al supports or the like provided in conjunction with a support frame. Spring clamps attached to the sup-port frame are used to hold the bag or bin mouth open dur-ing filling of the bin with bulk material.
After filling, the bin can be transported to a storage or unloading site by the insertion of a pair of fork lifts of a forklift truck through the slings. The bin bottom was equipped with a solid paperboard one-way slide put in place during the bin construction. Access 20 from one side only was possible and no handle was includ-ed. Complete removal of the slide valve or gate is neces-sary to initiate product withdrawal through a circula~
opening or hole centered in the bottom of the bin. How-ever, no means were availablP to vary or stop the flow or 25 removal of the product once the slide valv2 or gate was removed.
In order to rectify this condition and to provide control over the rate of flow or discharge of the bulk material from the bin, the bin bottom is provided with a double wall including a pair of aligned dispensing open-ings. A slide valve is inserted between the panels of thedouble wall of the bin bottom and has an off-center open-ing which can be placed in registration with the openings in the double wall to dispense the bulk con~ents o~ the bin. The flow o~ material from the ~in can be controlled 10 by partial in lieu of full registration of the dispensing openings in the bin bottom and slide.
However, if the bin is opened with the slide valve too far to one side or with insufficient extension from both sides o~ the bin bottom wall, the slide may be 1~ inoperable Eor its intended purpose either because it will be pinched or incapable of being slid axially along the bottom of the bin from one side thereof against the down-ward force of the great weight and bulk of material housed in the bin, or the slide valve cannot be gripped to be 20 pushed and simultaneously pulled from opposed sides of the bin. Accordingly, the slide valve is provided with han-dles on both opposite, lateral ends thereof, which are ac-cessible from both sides of the bin when the hole in the slide valve is in regi~tration with the holes in the bin 25 walls.
The handles may be cut openings in the slide valve or the valve may be doubled back upon itself at its opposite ends and fastened and a dowell inserted through the looped back portion to serve as a handle member.
Further objects and advantages will become ap-parent from the following description and claims, and from the accompanying drawings, wherein:

Referring now to the drawings in detail, where-~n like numer~ls indicate like elements throughQu~ ~h~
~everal views, the bulk contain~r or sling bin 10 of the pre~ent invention can include a bag member 11 having a 5 sidewall 12 provided with looped extensions or slings 14, 16 formed by bending each of the ends of auxiliary side-walls 13, 14, and bottom wall 18 secured to opposed por-~ions of sidewall 12 and bo~tom wall 17 of bag 11 respec-tively, in a loop back upon itself and adhesively secur-10 ing the loops or slings t~ the adjacent auxiliary sidewallmember. Bag 11 can be constructed of kraft paper, poly-ethylene, aluminum foil/paper laminates, or o~her materi-als such a~ wov n fabrics of polypropylene, polyethylene, or other synthetic or natural produets. Addi~ionally, a lS polyethylene liner (not shown) can be inserted into bag 11 for product protection. The auxiliary sidewalls 13, 15 and bottom wall 18 each contain an inner and outer ply of stiff paper matPr~al or wo~en synthetic fabric, the inner plies being de~ignated 13a, 15a and 18a, while the ~u~er 20 plies are designated 13b, lSb and 18b, respectively.
Typical materials which can be used for auxiliary side-walls 130 15 and bottom wall 18 are fiber reinforced kraft paper and woven polypropylene. The auxiliary sidewall plies 13a, 13b and 15a, lSb are adhesively bonded to each 25 other, except along bottom wall portions 18a, 18b for a purpose t~ be described hereinafter.
As shown in FIGURE 5, the bin 10 can be ~uppor~
ed on a fxame 22 ~y inserting looped extensions or slinqs 14, 16 on a pair of bars or pipe support~ 24, 26, re~pec-30 tively, on frame 22. The ~in mouth 2~ is openPd and ~pringclamps 28 are all connected between the mouth and frame ~2 to hold the mouth 2~ open. The combined bottom w~ll 17, 18 can be supported on a aOlly D. ~he bin 10 can ~hen be filled with bulk material from a tube T and after filling, the bin 1~ c~n be closed and transported to storage ~x an unloading si~e by ~he insertion ~f a pair of fork lif~
27, 29 of a forklif~ truck through the slings 14, 16.
~FIG~RE 6).
S The bin bottom wall panels 17 and 18a, 18b are provided with regis~ered openings 30, 32, and 41 respec-tively. Reoeived between unsecured, spaced plies 18a, 18b o auxiliary bin bottom 18 is a slide valve plate 34 hav-ing a coating of silicone or polyethylene ~o reduce slid-ing friction. In general, slide valve plate 34 can be constructed of any thin material strong enough to hold the bulk material M contained in bag 11 while closed, and to be opened and closed unaer load. A low coefficient of friction is desired in order to facilitate sliding the valve. Typical materials include heavy duty kraft paper, liner board, synthetic plastic sheets of polyethylene, polypropylene, ~ylon or polycarbonate, or a laminate or sandwich of any of ~hese materials. The slide valve 34 is provided with openings or handles 36, 38 on both oppo-site, lateral ends thereof, along with off-center opening 4D extending therethrough, which is adapted to be placed - into and out of full ox partial registration with open-ings 30, 32 and 41 in bottom wall 17 and plies 18a, 18b to control the flow rate and dispensiny of bulk material M
from bin 10, as shown in FIGURE 7, from the interior of bi~ 10, through spenings 30, 32, 40 and 41. The handle openings 36, 38, because of th~ off-set nature of opening 40, are acces~ible from both sides ~ the bin 10 when the opening 40 in the slide ~alve 34 is in partial or full registration with the holes or openings 30, 32, and 41 of the bin ~7~ 17 and 18a, 18b.
As shown in ~IGURES 8 and 9 the handles may be ~o~ned by doubling back upon itself the slide valve 34 at its opp~site ends and fastening the valve to îtself by staples or the lik~ as shown at 42. A dowel 4~ inserted -B-through the looped back portion of slide valve 34 aids in gripping slide valve 34 through openings 46 cut in each looped end portion of slide valve 34.
Circumferential structural support can be added to bin 10 by providing a girdle 50 around bag 11 and aux-iliary sidewalls 13, 15, as shown in FIGURES 10 and 11.
Girdle 50 can be constructed of laminated, fiber reinforc-ed kraft paper, or the like and in the form of a sleeve which is installed around the periphery of bag 11 and aux-iliary sidewalls 13, 15. Girdle 50 is secured to bag 11by adhesive means, such as glue spots located at various points on the interior surface of girdle 50. ~irdle 50 includes a seam 52 which is adhesively sealed along its length.
It has been found that a girdle is useful when bag 11 and aux.iliary sidewalls 13, 15 are constructed of paper materials, to add necessary strength to the overall bin assembly. Such a girdle has been found to be unneces-sary when bag 11 and auxiliary sidewalls 13, 15 are fabri-20 cated from stronger, woven synthetic fabric materials.
