BOX

12 Claims.

This invention relates to boxes for fragile articles and particularly to egg carriers.

The primary object of this invention is to provide a box in which eggs or fragile articles may be packed, stacked, and shipped in such a way that said eggs and articles are completely protected against breakage, without the use of heavy and bulky crating.

Another object of the invention is to provide a box of light material so constructed that stresses caused by stacking are taken why certain elements of the box without any pressure on the eggs or other articles packed in said box.

Another object of the invention is to provide a box, and cellular packing means in the box in such relationship that a larger number of eggs or other articles can be packed in agiven space than heretofore accomplished, yet complete protection is afforded to prevent undue stress on the contents of the box, the box being made of comparatively light material.

Another object of the invention is to provide shipping box and particularly an egg carrier which is highly useful and simple in construction. Convenience of arrangement, lightness and comparative inexpense of manufacture are further objects which have been borne in mind in the production and development of the invention. v

I am aware that some change may be made in the general arrangements and combinations of the several devices and parts, as well as in the details of the construction thereof without departing from the scope of the present invention as set forth in the following specification, and as defined in the following claims; hence I do not limit my invention to the exact arrangements and combinations of the said device and parts as described in the said specification, nor do I confine myself to the exact details of the construction of the said parts as illustrated in the accompanying drawings.

The invention is clearly illustrated in the accompanying drawings, wherein Figure 1 is a perspective view partly in section of an assembled box and packing constructed in accordance with my invention, the upper portion of a lower box in stacked position being shown in broken lines.

Figure 2 is a perspective view of the lower portion of the box with the bottom flaps unfolded.

Figure 3 is a perspective view of the cover of the box with the top flaps unfolded.

Figure 4 is a plan view of the blank for the cover of the box.

Figure 5 is a plan view of the blank for the lower'portion of the box.

Figure 6 is a plan view of the blank fora modified embodiment of the lower portion of the box.

Figure 7 is a bottom perspective view of the modified box with the bottom partly folded.

Figure 8 is a bottom perspective view of the modified box with the bottom completely folded.

Figure 9 is a top perspective view of the box, 10 showing the partition linings in position.

In carrying out my invention I make use of a substantially rectangular strip l6, which is provided with spaced, transverse flexible joints ll, by scoring or creasing, to form the corners of the box. At an end of the strip I6 is a transverse flap l8 whereby the ends of the strip I6 are secured to each other in any suitable manner. The flexible joints ll divide the strip I6 into longer and shorter sides l9 and 2| respectively, the former forming the sides, and the latter the ends of the box.

From the lower edge 22 of the strip l6 extends a flap-strip 23, which is divided by slots 24 into longer and shorter flaps 26 and 21 respectively along the lower edges of the sides l9 and ends 2|. The strip l6 and the flap-strip 23 are scored at their joining longitudinal edge to form a longitudinal flexible joint around which said flaps can be folded toward each other. The width of the 30 flap-strip 23 is about one half of the width of the strip l6, or slightly wider. Each end flap 21 is scored or creased longitudinally at about the middle of its face so that each end flap 21 can be folded upon itself around the flexible joints formed by said crease at 28 thereby providing a spacing cushion at each end of the bottom of the box. The bottom flaps 26 and 21 are secured together in any suitable manner.

In the modified embodiment shown in Figures 6, 7, and 8, the flap-strip 23' is scored or creased at 24' to form flexible joints thereat for flaps 26' and 21'. The flaps 21 are the shorter flaps and are scored at an angle, so as to provide a flexible joint 28 from each comer of .each flap 21', adjacent the lower edge 22' of the strip l6 converging to a point at about the middle of the free edge of each flap 21'. When assembled the flaps 21' are folded upon themselves around the creases or flexible joints 28', and at the same time the flaps 26' and 21' are folded toward each other, so that the doubled flaps 2'! are on the outside of the bottom of the box and form spaced cushions, one at each end of the bottom. The flaps 26' and 21 are secured to each other in any suitable manner.

A cover 29 is also formed of a substantially rectangular strip, which has its ends secured to each other in any suitable manner by the use of an end A telescope over the respectivev sides of the lower portion of thebox.

Along the upper edge of the cover 29 is an integral flap-strip 36 joined to the cover by a crease or flexible joint 31, and divided by transverse slots 38 into longer top flaps 39 and shorter flaps 4! respectively opposite to the sides 33 and 34 of the cover. The shorter flaps 4| are folded on the inside of the top under the longer flaps 39 and rest upon the upper edges of the sides l9 and 2| when the cover is on the box so as to space the remaining portions of the top from saidedges. The top flaps are secured to each other in any suitable manner.

In the event the boxes are shipped empty both the lower portion of the box and the cover can be diagonally collapsed-around their respective flexible corners so that a large number can: be shipped or stored fiat. If the cover is telescoped over the lower portion of the box, then, before the top and bottom flaps are folded, the cover and the lower portion of the box may be collapsed and flattened together as a unit, if necessary.

As it is the usual practice in egg carriers the box is divided transversely into two equal compartments. This may be accomplished by a single, corrugated sheet that fits across the inof linings 42 and 43. Each lining is preferably made from a strip of corrugated fiber board transversely scored or creased to provide transverse fiexible joints which constitute the corners of the lining when the sidesbetween the adjacent joints are folded at right-angles. The strips and sides are of such length that each lining confines a space of substantially rectangular cross-section of about one half of the entire box in cross section. Thus three sides of each lining slidably fit against an end and one half of each adjacent side of the box, and the fourth side of each lining extends parallel with, and intermediate between the ends of the box, and forms a partition. This partition 44 is therefore a double-wall partition securely positioned by reason of the location of the linings 42 and 43: The strips of the linings are so cut that the corrugations of lining 43 are at an angle, preferably at right-angle, to the corrugations of lining 42, so as to provide a more rigid double partition 44.

The box heretofore described provides a highly eflicient egg carrier of comparatively light weight and small bulk; 'The box may be stored in fiat- Q tened, collapsed position. When in use the botat the ends of the top of the lower box and taken up through the inner cushion flanges of the top resting on the upper edges of the sides of the box. The spacing of the bottoms of the boxes from the respective tops of the boxes below them by the bottom cushions provides an air space or passage between the superposed boxes of the stack, which allow free circulation of air and facilitates air conditioning or refrigeration around said boxes in shipping or storing. In this manner full protection is afforded to fragile articles, without any use of heavy and bulky cratings.

Having thus described my invention what I claim and desire to secure by Letters Patent is:
