CHARLES E. LA FLEUR, OF PHILADELPHIA, PENNSYLVANIA.
EGG-CASE FILLER.
Specification of Letters Patent.
Patented Apr. 20, 1925).
Application filed January 9, 1919. Serial No. 270,387.
To all whom it may concern Be it known that I, CrrAnLns E. LA F LEUR, citizen of the United States, and resident of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented an Improvement in Egg-Case Fillers, of which the following is a specification.
My invention has for its object the construction of an improved collapsible eggcase filler adapted to be assembled within a suitable case to provide hexagonal cells or pockets for reception of.the eggs to be packed for shipment, which is stronger and more easily shaped than devices for this purpose heretofore in use.
As far as I am aware, the most satisfactory "egg-case filler heretofore in use, is of the type set out in Letters Patent No. 621,609 dated March, 1899; but while the general features therein set out were desirable, the filler elements employed therein contained features of weakness, which it is the object of my present invention to overcome. In the aforesaid egg-case filler, the filler strips of straw or wood pulp board were provided with incisions trai'isversely of their length to permit of the bending nec essary to insure the hexagonal cell form required and to provide for the collapsible capacity to the filler for storage or transportation preliminary to use. The straw or wood pulp board is naturally of little strength because of the short fiber of the material employed, and the making of cuts or incisions therein across the entire width adds greatly to the weakness and permits rupture under rough handling which the crates frequently receive. The breaking of the filler itself would not be so serious a matter, but its rupturepermits undue strain to come upon the eggs .under shock and causes great loss by breakage thereof. The
loss from this cause is enormous, when con-' sidering the gross output requiring transportation during any year. My object is to overcome this weakness, by providing a special construction of strip from which the filler is formed, as hereinafter set out.
My invention consists of a filler element formed of a strip of straw or wood pulp board having transverse compressed or densified portions which reduce the thickness at such places to provide integral flexible hinge parts capable of being freely bent in either direction without rupture; and in the preferred form of my filler strip I provide the transverse hinge portions each with one or more apertures or cuts entirely through the board to reduce the length of the actual hinge portions and impart increased flexibility, the said apertures or through cuts also providing means for ventilation and permitting the top and bottom edges of the strip to be continuous.
My invention also comprehends other details of construction which, with the features above stated, will be better understood by reference to the drawings, in which: I Figure l is an elevation of a portion of a filler strip before being bent into shape; Fig. 2 is a plan view showing the filler strip bent into final shape; Fig. 3 is an e11- larged edge view showing the strip with the densified hinge portions; Fig. l is a sectional view on line aw ofFig 1 showing the transverse perforations; Fig. 5 is an edge view of strip showing a modification of the hinge portions; Fig. 6 is a plan view of a suitable partition board to be employed between the fillers; Fig. 7 is a cross section thereof; Fig. 8 is an elevation of the fillers with an interposed partition board, the latter in section; Figs. 9 and 10 are elevations of modified forms of filler strips embodying my invention; and Figs. 11 and 12 are enlarged views illustrating the form of the compressed or densified hinge portions of the strips embodying my invention.
The filler strip 2 is of uniform width and of a length sufficient to provide a predetermined number of panels 5 and two half end panels 5. The number of panels 5 required in the strip will be dependent upon the num ber of cells to be formed therefrom. In the illustration I have shown four cells (Fig. 2) by way of example and this will require 29 panels 5 and two end half panels 5 The panels are integrally connected by the hinge portions a which are formed by compressing or densifying the strip 2 on a plurality of transverse lines as indicated. The densification may be by depressions from opposite sides equally as shown in Figs. 3, 4, and 11, or from opposite sides, more or less alternately, as shown in Figs. 5 and 12; but no fiber is cut or severed where the hinges are formed and because of this, the dense tough hinge portions provide great flexibility coupled with strength. In Figs. 11 and 12 I have shown the densified hinge portions 4 with a. form of reverse curve to make them more freely flexible in either direction.
- portions 4- above and below the slots or apertures. in Fig. 9 I have shown two slotted portions 3 between each of the panels so as Y to pronde three hinge portions l. in Fig.
I! 10 l have shown a large number of periorations 3 in alinement with the hinge portions between adjacent panels and this pro vides astill reaternumber of hin )ttltS {J b of less individual length. It will be understood that, because of the great toughness of the hinge portions l, it is possible to shorten their length to give the desired elasticity and this is accomplished by provid ing the perforations 3; and these perforations moreover, provide means of ventilation between the cells of adjacent filler elements.
When the strip 2 is properly stamped and perforated, it is bent up into the form shown in. Fig. 2 and the abutting panels and half panels are glued. together as customary. A plurality of such sections are then placed side by side and abutting panels are glued together, so that a honey-comb structure is provided to constitute the filler. This structure is collapsible to fold down flat for shipment or transportation, all of which would be customary practice as set out in my former patent herembefore referred to.
Similarly, it is customary to set the fillers one upon another withan interposed partition board which performs the dual func- ,tion of supporting the eggs and the fillers "thereby provided weak cornered portions.
themselves, and I have shown this feature in Fig. 8. The partition board 9 is of straw orwood pulp and stamped with raised portions 10 upon opposite surfaces,-those.upon one side being staggered with those upon the opposite surface. These raised portions act, more or less, as cushion supportsfor theeggs and provide an irregular surface which engages the continuous edges 6 of the fillers and holds them firmly in position. In my former patented construction, the edges of the filler'werenotched for ventilation and which, under violent handling, had a tendency to break down and permit rupturing of the filler, with consequent injury to the i' g -i c i In. the construction, as shown, I have made the perforated portions 3 pronounced as to size of openingfor thepurpose of making the ventilating feature more apparent, but I in no way desire to be restricted, either as to size or number of these open or slotted portions. In other words, a clean 7 through cut or perforation without fiber re :moval Wlll be capable of ventilation and,
of these being equivalent structures embodying my invention. 7
In practice, the hinge portions 4 are densified or compressed to reduce their thickness, so that they may be easily bent when forming the filler section,also during collapsing for storage or transportation, or for opening up for actual use in shipping eggs. As none of' the fiber is cut or broken, the hinge portions are very strong and capable of rough usage without rupture. This den sifying of the strip to form the hinges may be equally performed from opposite faces as indicated "in Figs. 3, 1, and 11, or may be mainly performed from one side, as indicated inFigs. 5 and 12. As shown in Figs. 11 and 12, the densified hinged portions 4 may be formed by reverse curve compressions at the place of the densifications, with the result that the hinges are moreflexible and less liable to breal age and may be bent outward or inward, as preferred, with equal facility. r
It will now be understood'that my improved filler section embodies great flexibi-lity and maintains a maximum of strength, may be freely bent in either direction at the hinge joints, is formed with continuous edges'at top and bottom, and provided with capacity for free ventilation; V V
These strips may be conveniently formed by passing thesheets between creasing and perforating rolls, or the board may bein large sheets, which may be subsequently split orslitted into thenarrow strips shown; It is also evident that thecreasing and perforating may be done as two operations, if
so preferred. I do not restrict myself in" these respects. 1 r V I have described my invention with that particularity which I deemed-thebest exposition of the im rovements, but I; do not .restrict myself to he exact features set out as these may, within the scope of the claims,
he modified without departing-from the each perforated alongtheir length intermediate of itsends to form ventilating means at a distance from the edges and separating a plurality of short hinges, the structure providing connected panel portions which are relatively positioned by folding to form polygonal pockets connected by two-ply panel portions, the panels of said two ply portions being glued together to retain the strip in its folded form with capacity for being expanded or collapsed as required, combined with intermediate partition boards having their opposite surfaces provided with pliable projecting portions withwhich the continuous edges of the filler sections engage.

An egg-case filler strip comprising a long strip of fibrous sheet material having continuous straight parallel edges, said strip having its length divided into a plurality of panels integrally connected by transverse hin 'e portions formed of densified fiber to a thickness greatly less than the thickness of the sheet material and compressed with a reverse curve or ogee cross section whereby it may be freely bent in either direction, said strip folded upon itself and having a portion of the abutting panels secured together whereby a filler section is provided capable of being opened to provide polygonal pockets.
8. An egg-case filler strip comprising a long strip of fibrous sheet material having continuous straight parallel edges, said strip having its length divided into a plurality of panels integrally connected by transverse hinge portions, said hinge portions between each pair of panels separated by a ventilating perforation extending entirely through the strip and in alinement with the hinge portions and at a distance from the continuous edges of the strip.
