9 Claims.

This invention relates to a new and improved shipping case and method of making the same from fibreboard.

It is a main object of the invention to provide a method of making from fibreboard a shipping case particularly adapted for the shipment of eggs and similar fragile articles.

Another object of the invention is to provide a fibreboard egg case having standard dimensions.

Another object of the invention is to provide an egg case that is closed by a cover which is locked on the case at both ends and in the middle, and is capable of being completely removed from the case.

Still another object of the invention is to provide a new and improved cover for an egg case that fits entirely within the boundaries of the I vide a fibreboard egg case that has smooth, planar outer and inner side walls and ends.

Another object of the invention is to provide in ashipping case a central partition that is securely fastened to both side walls andvto the bottom of the case.

Still another object of the invention is to provide a fibreboard shipping case that is strong and light and capable of being manufactured at low cost.

Further objects of the invention not specifically mentioned here will be apparent from the detailed description and drawings which follow, reference being had to the following drawings in which a preferred embodiment of the invention is shown by way of example, and in which:

Figure l is an isometric view of a preferred embodiment of the invention at one stage of its assembly;

Figure 2 is an isometric projection of a slightly modified form of the invention partially assembled;

Figure 3 is a cross-sectional view taken longitudinally through a case and showing still another form of the invention;

Figure 4 is a cross-sectional view taken longitudinally through the case and showing still another embodiment of the invention; and

Figure 5 is an exploded view in isometric pro jection of still another embodiment of the invention.

Standard egg cases, for example, heretofore mainly composed of wood, have certain definite width, which must be maintained if the cases are to pack properly in freight cars and trucks. Recently fibreboard cases have been employed in lieu of wood as a war measure, these cases being composed either of so-called corrugated board or in some instances of solid fibreboard. Insofar as I am aware, none of these prior art fibreboard cases has maintained standard length and width coupled with standard egg space, with this space surrounded by smooth, flat Wall surfaces capable of permitting proper insertion and removal of standard fillers and flats.

Corrugated fibreboard, in particular, is more resilient than wood and when properly constructed to standard dimension on the fibreboard case is capable of carrying eggs in shipment with less damage than is encountered in wooden cases. It is to this end that the present invention is directed.

In the-preferred embodiment of the invention fibreboard cases composed of either corrugated or plain board are built to standard outside dimensions and are provided with full-size egg space surrounded by smooth planar walls. Adequate cushioning is provided in both ends of the case to take up end shocks encountered in shipping. The partition by which the case is divided into two egg spaces, is securely anchored to the bottom and both sides of the case, and is constructed so as to provide adequate cushioning between the two sections of the case.

Formed in the end sections and partition of the case are grooves adapted to receive tongues on the cover of the case and disposed within these grooves are looking elements adapted to engage co-operaktive elements in the tongues on the cover to lock the cover on the case at both ends and in the middle. This arrangement improves upon the standard wooden egg case whose cover is fastened only at the ends. The cover of the instant invention is composed of fibreboard, either double-faced corrugated or plain, and is positioned on the top of the box with air spaces along the edges to permit proper ventilation of the contents.

' The cover does not overhang the case on the sides and can be removed from the end of the case to permit necessary inspection of the case, even though it be in position in a car with other cases firmly abutting against it on either side.

Referring now to the drawings in more detail, particularly Figure 1, wherein there is shown a case capable of being formed from a single sheet of stock, which sheet is cut and scored to form a bottom section I and side sections 2 and 3;

tending from the bottom section I of the blank are members 4 and 5 which form part of the end of the case. Extending from the ends of side section 2 are extensions 6 and I and from the side sections 3 are extensions 8 and 9 which extensions also enter into the ends of the case, as will presently appear.

Disposed on the bottom section I is a liner indicated generally at II), and consisting of an end section II and bottom section. I2 and tongue I3, which may be formed by folding the liner back upon itself to place two thicknesses of material in the tongue, another bottom section I4, and another end section I5. If desired, the liner may be made from two pieces of material, each folded 1 to generally U-shape and these pieces secured together to place two thicknesses of material intongue I3.

Stapled to the side member 2 is a partition element I6 and stapled to the side section 3 is a partition element I'I. Partition element I3 has side members I8 and I9, which are of such height as to extend to the top edgeof the side and of such width that they will extend to the longitudinal median line of the case. has similar sections 20 and 2| which are of identical dimension.

In assembling the case, liner I is placed upon the bottom section I and one of the sides, 2 for example, is folded along its score line 22 into position at right angles to the bottom section I. Sections I8 and I9 of partition member IB are folded onto opposite faces of the tongue I3 on the partition and secured thereto in any preferred manner, such as by stapling. 6 and I on side 2 are folded on their respective score lines into position alongside of and outside of end sections II and I respectively of the liner.

Side section 3 of the case is next folded along 5 its score line 23 into vertical position and sections and 2I of the partition means I! are folded alongside opposite faces of the tongue I3 and into abutment with sections I8 and I9 respectively. Sections 20 and 21 are secured to the tongue in any preferred manner, as by stapling. End sections -8 and 9 of the side 3 are then folded along their respective score lines 24 and 25 into position outside of and adjacent to sections 6 and 1 respectively.

End section 4 of the bottom I is next folded along score line 26 outside of end section 8 and then bent along score line .21 over the top of sections 6 and 8 and bent again alon score line 28 downwardly on the inside of sections 6 and 8 into abutment with the upper edge of section II of the liner. Sections II, 5, 8 and 4 are then secured together by suitable means, such as staples, to complete the one endof the case.

In a similar manner after sections 1 and 9 have been folded alongside of each other, bottom section 5 is folded along score line 30 up over the outside of these sections and then folded alon score line 3i across the top thereof, and again folded along score line '32 down on the inside of section I to bring the inmost portion 3310f the extension into abutment with the top edge :of liner section I5. The end is then secured together by suitable means, such as staples.

It will be noted that section 6 and 8 are cut away as indicated at and 36 respectively, so that when folded together between the liner and outer element in the end ofthe case, a groove will be formed. The portion of the end section 4 between score lines 21 and 28 contain gener- Partition member I5 s ally rectangular perforations 31 and 38, which register with the groove so formed. Similar grooves 40 and 4| in members i and 9 respectively form a groove with which perforations 42 and 43 in the portion of end section 5 between score lines 3I and 32 are registered. The upper edge of tongue I3 is cut away as indicated at 45 to form a groove between partition members I8, I9, 20 and 2I and generally T-shaped tongues 46 and 41 are disposed Within this groove, for a purpose which will presently appear.

The cover 50 may consist of a single piece of stock folded back upon itself to form a central tongue 5| having two thicknesses of material and folded back upon itself to form an end tongue 52 and a second end tongue 53, both of which are composed of two thicknesses of material. Obviously, if desired, the cover may be made of two pieces of material joined together in tongue 5| by suitable means, such as staples, in lieu of the single piece construction shown.

Formed in the tongue 5| are lockin means including shoulders 54, which are adapted to be registered with and engage complementary shoulders on tongues 45 and 41. Tongue 52 contains similar locking means having shoulders 55, which locking means register with the rectangular perforations 31 and 38 in the one end of the case to secure the cover thereto. It will be noted that shoulders 54 are spaced farther from the underside of the cover than are shoulders 55, so as to register properly with the locking means in the case. Tongue '53 is provided with similar locking means having shoulders 56 which locking means registers with the perforations 42 and 43 in that end of the case.

To position and lock the cover on the case the cover is first moved downwardly to register the tongues with their respective slots and then moved laterally to engage the locking shoulders.

The case thus formed contains four thicknesses of material in each end and four thicknesses of material in the partition. It has a double bottom and single thickness side walls. The egg receiving cavities within the case are of full size, and are surrounded by smooth planar walls which facilitate easy insertion and removin of the packing elements with which the case is filled. The cover which also consists of a single thickness of material is securely held on the case at both ends and in the middle, and since the partition is securely fastened to both sides of the case, and if desired may also be fastened to the bottom by fastening the liner sections thereto in suitable manner, such as by stapling, the resulting structure is exceedingly strong and particularly adapted to resist endwise shocks placed .upon it. The outer surfaces of the case are all smooth planar surfaces, thereby permitting the case to be stacked adjacent to other cases in a tight pile, better enabling the case to withstand shocks placed upon it in shipment.

The case shown in Figure 1 may be provided with handholes in the end, as hereinafter explained, these holes being omitted from the drawing to avoid an unnecessary complication thereof.

Figure 2 shows a case constructed in the same general manner as Figure 1 except that the end sections 60 and 6| of the liner are carried up to the top edge of the case and the end extensions 62 and E3 of the bottom sections are terminated flush with the top edge of the sides. Grooves 64 are formed in the end walls of the case as before and tongues 65 projected into those grooves as before.

The partition shown in Figure 2 employs a slightly different construction than that shown in Figure l. Tongue 66 of the liner is employed as before and one partition member 61 is equipped with a footlike projection 66 that is secured to one side wall 69 of the case by suitable means, such This partition member extends from the liner to the top of the case and is wide enough to extend across the case into abutment with the other side wall 16 thereof. A second partition member H is disposed on the other side of the tongue 66 and provided with a foot I2 that is secured to the side wall 16 in any preferred man ner, such as by staples, the partition member H also extending from the liner to the top edge of the case and across the case into abutment with the side wall 69. The tongue 66 and partition members 61 and H are secured together in any suitable manner, such as by staples.

Tongue 66 is equipped with locking means 13 that project into the groove 14 formed between the partition means 61 and H at the top edge of the case.

The cover shown in Figure 2 is similar to that shown in Figure 1, having single thickness main members 15 with a double thickness tongue 16 I 65 and '13 disposed in those grooves.

The covers shown in both Figures 1 and 2 are somewhat narrower than the case to provide for top ventilation of the case and areinserted and locked on the case first by a vertical movement. and then by a horizontal movement laterally of the case. In certain instances it may be desirable to double-lock the cover, and the construction shown in Figure 2 lends itself particularly well to this feature.

Projecting upwardly from the one side wall 19 is a flange 80 joined to the side wall alonga score The ends of the flange 80 extend bethat they may be folded back upon themselves to form double thickness tabs 82 which project at right angles to the flange 80 and are adapted Y to fit into the grooves 64 in the ends of the case.

After the cover has been movedlaterally to'lock it on the case, flange 86 is bent along scoreline BI and tabs 82 stuffed down into the groove'alongside of the tongues on the cover therein to prevent lateral movement of the cover. The flange 80 is then disposed in abutment with the edges of the cover, A flange similar to 89 will be provided also in the partition, two thicknesses of material in the bottom and a single thickness of material in each side and in the cover. The egg receiving spaces in the case are. full-size and bounded bysmooth planar walls and the outside surfaces of the. case are all smooth planar surfaces, free from obstruc- Handholes such. as indicated at 83 may be provided in each end of the case, if desired. The case shown in Figure 2 is formed from a single sheet of material by fold- .ing in the manner more fully described in connection with Figure 1. The liner may be formed from a single piece of material suitably bent to form, a double thickness center tongue, or may be formed from two pieceso rmat riali ined togather in the tongue by suitable means, such-as staples.

case. In this figure the bottom section of the case 90 has end extensions 9! and 92 folded upwardly to form the outer surfaces of the ends of the case. The one side 93 of the case has projections 94 and 95 which are folded to form one member in the The other side wall, not shown in Figure 3; has similar end projections 96 and 91 folded to form an additional thickness of material in the end walls of the case. Extra pieces 91 and 98 are built into the end walls of the case and extended to the top edge thereof. 1

i The sections 94 and 96 of the one end of the case are cut away as shown in Figure 2 to form a grove disposed between the top edges of members 9| and 91, and locking means such as are projected into this groove. End wall sections 95 and 96 are similarly cut away to form a groove in the other end of the case and similar locking means, not shown, are projected into this groove. The partition is formed of a central tongue 98 having feet 99 disposed against the bottom arid projecting outwardly on opposite sides of the tongue 98. These feet are secured to the bottom of the case by suitable means such as staples. Locking means similar to means 13 in Figure 'z are formed in the top edge of the tongue 98. Partition members 96 each of which may be of the type shown in Figure 2 or the type shown in Figure 1, are disposed on opposite faces of the tongue and secured thereto by suitable means such as staples.

The cover I9! is of construction identical of that shown in Figure 2, having a central tongue I62 and end tongues I93 which are registered with the grooves in the case to position and lock the cover thereon. Secondary locking means, such as 80 of Figure 2, may be employed in this embodiment of the invention, if desired.

As will be seen in Figure 3, each of' the four thicknesses of material in the end wall of the case can be perforated as shown at 19 to form a handhold. The material thus cut from the case in the outer thickness of the wall being left attached at the upper edge of the perforation as shown at I04. The perforation in the third thickness of the material, for example, is wider than the perforation in the other thicknesses to form a slot I95, thereby permitting the tab I66 left in the outer thickness of materia1 92 to be folded along suitable score lines into the groove I05. The tab may be secured therein by suitable means, such as staples, and forms a smooth upper edge in the handhold, permitting a Workman to pick up the case without damaging the material in the end. walls. The perforations forming the handhold extends into the egg space in the case, thereby aiding to provide ventilation in those spaces. This type of handhold may be used in the embodiments of the invention shown in both Figures land 2. a
