3 Claims.
more particularly to an improved carton adapted to be employed for the storing and shipping of dry bulk materials comprising discrete particles.
In the shipping of such dry bulk materials, various types of shipping containers may be utilized. Bagging operations are a frequently employed expedient for the shipping of certain bulk commodities. However; the handling of bagged materials entails a relatively high labor cost. Since the bagged materials are usually handled manually at some stage during shipment, each bag can only contain but a limited amount of the bulk material. Furthermore, the; bags do not lend themselves very readily to handling by such labor-saving ecuipment as fork-lift trucks and the like without some manual operations. The use of square or rectangular corrugated paper cartons with a palletized base is a practical al- .ternative to thevse of bags in. the shiprling ani storage of bulk materials since the palletized base is readily adaptedto' fork-lift truck operations and greatly reduces handling costs. The advantages which are obtained by the use of palletized cartons are very greatly enhanced with increased carton size. Up to thetpresent time, the use of such corrugated paper cartons ofa size suflicient to hold two orrmore tons of bulk material of a relatively small, discrete particlesize has. been found to be impractical. The weight of the bulk .material exerts a substantial outward pressure on the walls of the carton and this pressure tends to bulge the same toward the cylindrical, particularly as the bulk material settles down and becomes more solidly compacted during transit. Where the pressure becomes sufliciently great the walls may be fractured and serious losses may thus result. Even if the pressure on the walls does not ultimately fracture the same, the carton distortion resulting from the outward pressure of said bulk materials makes stacking a very unsatisfactory and dangerous operation since-any change from the original square or rectangular shape prevents the stacked cartons from being set securely relative to eachother. Furthermore, if the distortion occurs after stacking, the outer cartons of the stack are pushed outwardlyto a highly unstable position while the inner cartons are wedged so tightly asto make their withdrawal substantially impossible without initially removing the outer portion of the stack.
It is, therefore, an important object of this invention to provide a carton of a novel structure whichis adapted to be employed for the storing and shipping of bulk materials in relatively large amounts without undergoing any distortion in shape during storage or transit.
Another object of this invention is the pro vision of a novel carton for the storage and shipment of bulk materials in relatively large amounts which is easily fabricated, assembled and sealed, and which may be readily handled by mechanical equipment not only for stacking and shipping but during discharging operations as Well.
Other objects of this invention, together with certain details of construction and combinations of parts, will appear from the following detailed description and the accompanying drawing.
In the drawing,
Fig. 1 is a view, in perspective and partly exploded, of the novel carton structure of my-invention, and
Fig. 2 is a sectional view of said novel carton structure takenalong the line 2-2 of Fig. 1.
Like numerals indicate like parts through the several views of the drawing.
Referring now to the drawing, and more particularly to Fig. 1 thereof, the novel carton of my invention, generally indicated by reference numeral 5, comprises a plurality of side walls '6, a base generally indicated by reference numeral 1 and a cover indicated by reference numeral 8. Base 1 comprises a flat sheet 9 cut and scored so as to provide flaps l0. Flaps ID are scored with parallel score lines so as to enable a double fold to be formed as shown in Fig. 2 by interleaving flaps Ill with flaps H which are formed by'suitable scoring and bending the base of each of walls 8. The interleaved flaps thus assembled are then joined, by suitable means such as staples I2 or by stitching, adhesive or the like, to form a firm stress-resistant union in the manner more particularly shown in Fig. 2. A plurality of legs l3 are also provided, said legs being suitably attached to base 1 in any convenient manner to support the weight of the carton structure uniformly and at the desired distance from the floor. Legs I 3 serve to form a series of passageways thereunder for the passage of the fork of 'a mechanical lift for fork-lift handling of the carton structure.
In order to provide a rigid structure whose outer walls 6 are adapted to resist deformation due to any force exerted thereon by the bulk material, there are provided a plurality of interior walls generally indicated by reference numeral l4, which interior Walls are firmly fixed to said outer walls 6 in a manner to be hereinafter described in detail. The interior walls, generally indicated by reference numeral 14, comprise a plurality of diagonally disposed walls l5 and a pair of centrally disposed dividing walls [6 and I1. Diagonal walls I 5 may be formed integrally with central walls [6 from a continuous sheet, as shown, or they may be formed of separate sections as in the case of central interior walls H. To provide the desired rigidity, central Walls I! are attached to wall i6 at the center thereof by suitable stapling or stitching [8. The opposite ends of walls I! are fixed to diagonal walls and to side walls 6 by stapling or stitchin 19 while central wall I6 is attached to diagonal walls I5 and to side walls 6 by stapling or stitching 20. Thus, side walls 6 are firmly held in position. and. any possible bulging or deformation due to the pressure of the bulk material in the carton structure is minimized due to the bracing effect of the in.- terior walls and to the uniform distribution of the stresses present.
In order to seal the carton structure 5 for shipment so as to prevent spillage, a telescopically fitted cover 8 isprovided, as mentioned above. Cover 8 comprises side walls 2 I. and flaps 22', the dimensions of side. walls 2i being such that when. cover 8 is slid on to the carton structure 5, a. fairly tight friction fit will result due to the resulting contact between the surfaces of cover side walls 21 and carton side walls 6.
When filling carton 5 with the desired bulk material, cover 8 is telescopically fitted on the outside of carton 6 so that about two thirds of itsv height projects above the topmost edges of carton. sidewalls S and. flaps 22 are bent outwardly in open fashion as shown in Fig. l. A liner of paper or' other suitable lining material (not shown) is preferably placed within the open cover 8 to form a chute for the loose hull; material to be placedv in. said carton and the bulk material is. then introduced. A sufficient amount of the bulk material is placed within the carton 5 to fill all of the separate sections thereof and to then fill the open cover 8 with a volume. of the bulk material equal to about 15 to of the capacity or" the carton proper.
The excess. is placed in the carton to compensate for the normal settling of the bulk material during transit. Flaps 22- are then folded over to close. the top and, after being sealed with gummed tape or adhesive, for example, cover 8- is pressed downwardly until the inner surfaces of flaps 22 are close to or touch the upper edges of outer carton walls 6. This acts to compress the contents quite solidly. To retain cover 8 in position, the cover and carton body thus assembled are then encircled with steel strapping (not shown) and, in strapped form the. carton i ready for shipment.
The novel structure of my invention is sufficiently strong and rigid to be fabricated in sizes large enough to hold several tons of bulk ma.- terial without being subject to bulging or other deformation or without placing an undue strain on the tape 23 and 24 joining carton walls 8 and cover walls 2!, respectively. The carton may be emptied by cutting the steel strapping, removing cover 8 and dumping the carton, or staples: 1.2 may be removed while. the carton is upright and the upper portion lifted away to allow the contents to discharge.
It is to be understood that the foregoing detailed description is given merely by way of il lustration and that many variations may be made therein without departing from the spirit of my invention.
Having described my invention what I desire to secure by Letters Patent is:
