PACKING DEVICE? Filed July 15, 1955 5 W m W INVENTOR WITNESSES m Patented July 14, 1936 UNITED STATES PATENT OFFICE This invention relates to a device for packing and protecting fragile articles of various kinds ,or

those which break easily, such as eggs.

on the inside thereof. The corrugations H thus ing feature The principal object of the invention is the provision of a simple, inexpensive, and effective device for protecting fragile articles or eggsto avoid breakage during transportation, and also making it possible to readily handle the same in the usual business transactions connected therewith.

The nature of the invention and its distinguish nd advantages will appear when the speciflca ion is read in connection with the accompanying drawing, in which-- i Figure 1 is a side elevation of a device em-- bodying the, features of the invention, portions thereof being broken away; I

Figure 2 is an end view of the device;

Figure 8. is a longitudinal section, the section being taken as indicated by the line 3, 3 of Figure 2, and an outer wrapper being shown applied to the holding tube or case.

The device of the present invention includes a flexible sheet I 0 of suitable size which may be In rolled to form a tube or cylindrical case which will be slit or divided longitudinally throughout its length. The sheet Ill in the present instance consists of corrugated fiber board rectangular in outline. The corrugations llextend longitudiprovide cushioning means on the wall of the tube or case formed by the sheet Ill. The sheet [0 is slit transversely at intervals to provide from the material of the sheet transverse portions l2 in the same plane at intervals throughout the length of the tube or case. Each of the portions l2 has its ends in continuation of the tube or case formed by the sheet, and is distended so as'to project inwardly of the tube or case as shown most clearly in Figures 2 and 3. These portions l2 constitute means to retain with a cushion eifect the articles,

'such'as eggs l3 within the tube or case, and also to prevent contact between the eggs at their ends.

The eggs are enclosed by rolling the sheet ll about them as will be understood.

In order to hold the sheet III in its tubiform', to give rigidity thereto, and to serve as a means for containing a printed advertisement, use ismade of one or more sheets of wrapping paper,

one sheet l4 being shown in the present instance. This sheet is wrappedaround the tube or case as at I5.

From the foregoing, it will be apparent that fragile articles, such as eggs, may be readily packed or enclosed for protection within a tube or case which provides a cushion for the articles to avoid breakage in handling or while in transit; and that the articles may be readily removed by unwrapping the sheet 4, and unrolling the sheet I claim: I

A packing device comprising-a corrugated sheet rolled to form a tube adapted to contain a longitudinal series 'of spaced fragile articles, a circular series of spacing devi s at each level between articles, each spacing device comprising an inwardlybowed section of the sheet between transverse slits in the sheet, said spacing devices projecting inwardly sufllcient to hold articles against longitudinal movement and of a longitudinal 'dimension suflicient to prevent any two articles Irom contact with each other. v
