PACKING FOR FRAGILE ARTICLES Filed Feb. 26, 1927 2 Sheets- Sheet 2 gvwemtoz 5% Carp Patented July 18, 1933 UNITED STATES PATENT OFFICE MORRIS KOPPELHAN, OF BROOKLYN, NEW YORK; ASSIGNOR, BY MESNE ASSIGNMENTS, TO PACKING PRODUCTS CORPORATION, A CORPORATION OF DELAWARE PACKING FOR FRAGILE ARTICLES Application filed February 26, 1927. ,Serial in. 171,120.

The improvements relate to devices for packing eggs and other articles and to boxes or cartons for containing the same, and are in the nature of an improvement in the subject matter of copending application Serial No. 122,7 7 7 filed July 16, 1926. The present improvements have for their objects, among others, the provision of novel and effective means for protecting the eggs or other articles from injury due to contact with outside objects or with one another during the packing, transporting and vending of the same and also the provision of a carton or box for containing a limited number of 'such articles which can be employed for the packing of eggs in standard cases, without decreasing the capacity of the case, and also in other boxes or enclosures, and can be adjusted to form a complete box or carton for various purposes without the employment of an outside box 01 case.

this may be accomplished by so shaping the The improvements are illustrated in the accompanying drawings, in which- Fig. 1 is a plan of a box or carton embodying the improvements, in open position;

Fig. 2 is a vertical medial section of the same on the line 22 of Fig. 1;

Fig. 3 is a vertical section substantially on the same line as that of Fig. 2 of the carton in closed position; and

Fig- 4 is a plan of one of the sheets with holders forming a part of the carton, but W gh hinge members and closing edges omitte The carton consists essentially of two sheets of material 1 and 2 with a connecting portion 3, these three elements being preferably integral, and formed in one operation, preferably by the pulp sucking or felting process in which floating fibres are drawn by suction against a screen, it being one of the objects of the improvements to so construct the entire device that it can be thus formed complete in one operation. The cups or holders 4, the separating and protecting ribs 5, connecting portions 6 and edges or flanges 7, 8, 9 and 10 of the two sides of the carton are also preferably made integral with the other parts in one and the same operation, and

foraminous die or forming sheet that the ulp will assume the form of the complete box when it is deposited thereon. Folding lines 11 may also be formed along the inner edge of each section in the same operation by introducing wires on the pulp side of the form, so as to reduce the thickness of the pulp sheet deposited along the same.

The dividing and protecting ribs 5 project above the upper edges of the cups or holders 4: and, above the substantially horizontal portions 1, 2, 3, and 6, and separate the cups 1ongitudinally and laterally. They are of greater thickness than the walls of the carton, and are substantially V-shaped, which may be the result of the crowding of the fibres into the narrow space between the folds of the form at that point. They thus form not only spacing and protecting ribs between the articles in the cups but form rigid connecting portions between the cups themselves which will prevent them from being easily deformed. They also will prevent the carton from being collapsed by coming in contact with each other when pressure is exerted and tion.

The portions 6' between cups are boarded by small ribs or beads 6', which serve to connect the ribs 5, hold the articles in position and greatly strengthen and add to the rigidity of the carton. The portions 6 are preferably made slightly concave or arched, and this tends to add strength and rigid ty.

The connecting or hinge portion 3 1s separated from the two sections by the folding lines 11, so that when one section is folded over' the other it forms the fourth side of the rim and makes a complete enclosure, the ends of this portion are not provided with flanges, so as to leave room for the flanges 9, 10, forming the rim of-one section to pass over and overlap the flanges 7 and 8 forming the rim of the other flange. The inner edges of the flanges 8 and 9 are preferably curved as shown at 8', 9' so as to facilitate this telescoping operation. At the bottom of each cup is provided a cushioning device in the form of two tapering ribs 12 crossing each other and extend- 'ing downwardly from the bottom of the tending part Hat the intersection of the ribs. The ribs 12 and bulged portions 13, merge in the smooth surface of the cup bottom a short distance from its extreme bottom, and together withthe portions 14 form a cushion which will receive the extremity of the egg or other article and the portions around ltS extremity and cushion it against any shock due to the dropping of the article into the cup or otherwise, at its ends. The formation is such also that the cushions have a slight gripping effect which tends article from movingaround in the cup freely. The construction of the-cushion is also such that it does not increase the de th of the cup, as the ribs are formed in e ect by forming the portions 13, and the portion 14 is an indentation at the intersection ofthe ribs 12. In this manner a cushion for both ends of the article is provided without increasing the depth of the cup, or the carton, so that the cartons opened or closed, or the separate sheets (Fig. 4) may be used in a standard case, without undue crowding or reducing the egg holding capacity of the case. It will be understood that the exact form of the parts embodying the present improvements is not essential, and that within the limits of equivalency they may be varied 1n form and arrangement without departing from the scope of the invention. It will also I be seen that the ribs 12 will rest upon an surface on which the packing is supporte and will space the cups when the are superimposed one upon another, bac to back, and that together with the bulged portions 13 and JIIdBl'ltBI-iOIlS 14, they willhold the articles out of contact with the supporting surfaces and out of contact with each other at their ends.

What I claim-is:

1. In a packing for fragile articles, a series of cup-like receiving pockets, connecting portlons uniting them at their upper parts, said pockets being contiguous to one another, and upstanding, separatingiand article protecting members extending upwardly above the receiving portions of the pockets and their connecting portions, one of said members being interposed between and merging with each pocket and the next pocket.

2.In packing for fragile articles, a series of cup-like receiving pockets, connecting portions uniting them at their upper parts, said pockets being contiguous to one another, and upstanding, separating and article protecting members extending upwardly above the receiving portions of the pockets and their to prevent the 4. In the combination of parts specified in claim 1 said protecting members being formed by continuing upwardly the walls of adjacent pockets.

5. In the combination of parts specified in claim 2*the connecting portions intervening between a greater number than two of said pockets being depressed below the upper edges of the pockets and having their edges forming with the said upper edges of the pockets, ribs separating them and the said pockets.

6.
