EGG CASES Filed Aug. 26, 1960 2 Sheets Sheet 2 INVENI'OR 17 Thomas 6. Mains Frank W lac/re ATTORNEY United States This invention relates to an improvement in egg cases and deals particularly with the type case used to contain thirty dozen eggs.
Eggs are shipped and stored in cases containing two compartments in side by side relation, each of which is designed to contain fifteen dozen eggs. One of the difficulties involved in these cases lies in the fact that considerable time and effort is often spent in erecting the case in readiness to be filled. In other words, it is normally necessary to take the fiat tubular blank and set it up and to stitch or glue the bottom end of the case to serve as a bottom closure. In many cases, particularly where the volume of eggs being packed is relatively small, the proper equipment for gluing or stitching the cases is not available. It is an object of the present invention to provide a case which may be shipped and stored in a fiat state and which may be opened up when desired in readiness to pack without the use of any machinery.
A further feature of the present invention resides in the provision of, a case having a solid bottom which is stitched or glued in place by the manufacturer and which may thereafter be folded for delivery and for storage.
These and other objects and novel features of the pres ent invention will be more fully and clearly set forth in the following specification and claims.
In the drawings forming a part of the specification:
FIGURE 1 is a perspective view of the case in closed position.
FIGURE 2 is a perspective view of the case in readiness to receive the eggs.
FIGURE 3 is a perspective view of the case in partially folded position.
FIGURE 4 is a longitudinal section on a vertical plane through the closed case.
FIGURE 5 is a transverse sectional view of the case in partially folded position.
FIGURE 6 is a plan view of the case in partially folded condition.
FIGURE 7 is a diagrammatic view of the blank from which the body of the case is formed.
FIGURE 8 is a diagrammatic view of the blank from which the case bottom and reinforcing end walls is formed.
With reference to FIGURE 7 of the drawings, it will be noted that the blank which forms the body of the case includes a side wall panel 10, foldably connected along the fold line 11 to an end wall 12 having a central fold line 13. The end wall 12 is foldably connected along the fold line 14 to the side wall 15. The side wall 15 is foldably connected along the fold line 16 to an end wall 17 which contains a central fold line 19. The end wall 17 is foldably connected along the fold line 20 to a side wall 21. The side wall 21 is foldably connected along the fold line 22 to a partition wall 23. The partition Wall 23 is foldably connected along the fold line 24 to an anchoring flap or flange 25. All of the fold lines which have been described are in parallel relation.
The side wall panel 21 is of a Width equal to one-half the side wall panel 15. Accordingly the partition wall 23 is located midway between the end walls 12 and 17 in the set up condition of the case. The side wall panel is of a width slightly greater than one-half the width ate t 3,943,279 Patented Aug. 14, 1962 of the side wall 15 so that it may be secured in overlapping relation With the side wall 21. The partition panel includes a central line of fold 26.
Flaps or flanges 27, 29 and 30 are foldably connected to the side wall panels 11 15 and 21 along fold lines 31, 32 and 33, these fold lines being aligned. The flaps 29 and 36 may be relatively narrow as it is necessary to extend only a small portion of the width of the case in set up condition.
Top closing flaps 34, 3'5, 36, 37 and 39 are foldably connected to the panels 10, 12, 15, 17 and 21 along a top fold line 40. The central fold lines 13 and 19 extend through the closing flaps 35 and 37.
Hand holes 41 and 42 are provided near the upper ends of the end walls 12 and 17. Short handle flaps 43 and 44 are hinged to the upper edges of the end holes 41 and 42, these flaps 43 and 44 being designed to fold inwardly as indicated in FIGURE 4 of the drawings.
The blank from which the bottom of the case is formed is illustrated in FIGURE 8 of the drawings. This blank is shown as having a central bottom panel 45 which is foldably connected along parallel fold lines 46 and 47 to inner end wall panels 49 and 50. The end wall panels 49 and 50 are provided with hand holes 51 and 52 therein which may register with the hand holes 41 and 42 in the end wall panels 12 and 17 in the set up condition of the case. The entire blank is centrally divided with a fold line 53 which extends intermediate the sides of the blank and through the bottom panel 45 as well as the end Wall panels 49 and 59.
The manner in which the body portion of the case is set up is best illustrated in FIGURE 2 of the drawings. As is indicated in this figure, the marginal edge of the panel It) is arranged in overlapping relation with a portion of the panel 21 and the ends of the flaps 27 and 34 are arranged in overlapping relation with the flaps 3i and 39 respectively. The edges of these panels and flaps are stitched or adhered together to form a tubular container. The flange 25 is folded in face contact with the inner surface of the panel 15 and is stitched or adhered thereto. In this way, a rectangular case having a center partition 23 is formed.
As is indicated in FIGURES 3 and 5 of the drawings, the marginal side edges of the bottom panel 45 is then stitched as indicated at 53 to the flap or flange 29 on the lower edge of the panel 15 and to the overlapped flaps or flanges 27 and 39 on the side walls It) and 21. With the inner end walls 49 and 5t folded up inwardly of the end walls 12 and 17 respectively, as indicated in FIGURE 4 of the drawings, the flaps 43 and 44 may be folded through the hand holes 51 and 52 of the inner end walls 49 and 50. The container is completely set up and is ready for filling.
If it is desired to collapse the container, this may be done in the manner illustrated in FIGURES 3, 5 and 6 of the drawings. As the first step of the operation, the panels 49 and 50 are folded down to overlie the bottom panel 45 as indicated by the arrows 54-. When this is done, the bottom panel 45 together with the superimposed end wall panels 49 and 50 may be folded along the fold line 53 as indicated in FIGURES 3 and 5 of the drawings. Simultaneously, the end wall panels 12 and 17 may be folded inwardly along the fold lines 13 and 19 respectively. At the same time, the partition panel 23 may be centrally folded along the fold line 26. While FIGURES 3, 5 and 6 show the case in but partially folded form, so that the manner of folding may be more readily recognized, the container can be folded into substantially flat form in the manner which will be readily understood.
The egg case described has certain advantages over egg cases of usual form. As has been previously mentioned, no particular tools or machinery are required to I erect the case into open form by the customer. Furthermore, after the case has been delivered and the contents of the case removed, it is possible to recollapse the case so that it may be. returned in flat form. With many types of egg cases, they are disposed of after a single use or else are returned in erected empty form which is normally uneconomical. A single truck can return many more cases in collapsed form than in erected form, as will be obvious.
In accordance with the patent statues, we have described =the. principles of construction and operation of our improvement in egg cases, and while we have endeavored to set forth the best embodiment thereof, We desire to have it understood that changes may be made within the scope of the following claims without departing from the spirit of our invention.
