Abstract: In an egg box made from slitted cardboard blanks of which one provides wave strips joined only at their wave crests for folding around to make pockets for the eggs and the other blank provides flat bottom and side panel or cover strips which brace the wave strips by being glued to the wave trough bottoms of the wave strips, top cover strips respectively glued to the half width wave strips that come together (when the top wave strips are folded around the eggs already packed in the pockets previously formed,) do not both correspond in width to the top wave strips, but one of them has an overlapping free edge the underside of which is bonded adhesively to the other top panel strip. The adhesive bonding is done with a hot-sticking adhesive which when cooled without being covered is no longer sticky. The adhesive is laid down in strips on the wider and shorter blank which provides the cover strips at locations corresponding to the wave trough bottoms that are to be glued on.

Abstract: A cardboard pack for eggs, or the like, is made of two slitted blanks, the longer one of which is bent into flat-topped and flat-bottomed waves. After the wave bottoms are bonded by adhesive to the flat blank, the wave tops are tucked in and the waves flattened mechanically. After the adhesive bonding, the solid cross-strips at the ends of the flat blanks become unnecessary and are cut off. Precautions are taken to avoid undesired adhesion of strips previously separated by slitting. With the waves flattened, the blanks can be easily stored or transported. The blanks are set up at the place of filling by mechanically raising the waves, bending up the sides of the back to form pockets, inserting the goods, bending over the top strips, and securing them together on their line of abutment. The shorter set of blanks is preprinted.

Abstract: Trays are erected from cardboard blanks by insertion of bent edge parts into slits in tongues, the extent of insertion dictating the carrying capacity of the resulting tray. The edge parts are bent with a double fold using mechanical fingers to give a wedge-shaped insertion structure for engagement with the slits in the tongues. To stiffen the blank and simplify insertion, side walls of the blank are first bent up by a bending tool and then subsequently insertion fingers are pivoted against the edge parts to form the double fold, and insert it into the slits of the tongues.

Abstract: A flat body portion of a holder for bunched bananas is suitable for application of a label and is suspended by an upper hook. Flexible arms extend downward from the body portion and each carries a barb or a cross arm at its extremity. In the case of a cross arm, in the unloaded condition, it hangs obliquely to facilitate insertion into a banana bunch. After insertion of the arms into the banana bunch, the arms are bent, so that the cross arms approach a horizontal position and support several bananas of the bunch, distributing the support, to avoid dropping the bunch by the breaking off of a single banana.

Abstract: In a pack for eggs or other fragile articles constructed of corrugated strips glued to and braced by external flat strips, in which the corrugated strips are joined together at their inner apices and folded at these junctions after the manner of U.S. Pat. Nos. 3,955,744 and 3,983,680, the closure of the pack is made along one of the narrower sides instead of along one of the wider sides, and at least one of the abutting narrow flat strips is provided with tongues of a length greater than the width of the strip that are stamped out of the material of one of the wider flat strips. These tongues are bent over so as to overlap the adjoining flat strip, where they can be glued to the flat strip to hold the pack together. The fastening is thus provided out of the material of the pack without waste, and no fasteners or adhesive strips need be applied from an external source in the packing operation.

Abstract: Bottom parts, overlapping on a longitudinal median strip and connected at bending lines with the long sidewalls of a folding box, are attached to the short sidewalls by connection flaps which have triangular ears glued to the adjacent short sidewall halves. The triangular adhering ears are bounded by 45.degree. fold lines from the remainder of the connecting flap. The lower bottom part has a shallow oblique cutout at each end with its apex on the folding line between it and the connecting flap, so that the upper bottom part will ride on it easily as the box is set up while blunt corners on the leading edge of the oblique cut-out press in to provide snap action as the box is set up by inward pressure on the short sidewalls. In the folded condition, the sidewalls are folded together along the midline of the narrow walls. The two bottom parts are fastened together by a sticking strip edge along the middle. The lower bottom part bends on a folding line at the edge of this strip as the box is set up.

Abstract: A flat blank of generally rectangular shape with rounded corners has a U-shaped incision in each end portion forming a tongue, extending endwise at each end from the portion that is to provide a tray bottom, that is separated by the incision from an end strip forming a continuous arch joining the portions that are to provide side walls for the tray. To set up the tray each end strip is folded inwards in the middle, the tongues are bent upwards and the most closely folded end strip mid-portion is pushed through a slot in the middle of the adjacent tongue, where it is held against flipping out by resilient flaps of the slot and by scollops or serrations on the upper edge of the folded-in strip bearing against the upper end of a slot. With different depths of insertion of the folded portion of the end strip through the tongue slot, different tray lengths can be provided with the same tray blank.

Abstract: A pack or container for the storage and transportation of fragile articles such as eggs, light bulbs and the like comprises a laminate consisting of a corrugated band or strip and a covering band secured together to give spaced troughs extending transversely of the material, there being spaced, parallel slits in the material extending in the longitudinal direction thereof, the slits extending wholly through the covering band to define separate side-by-side strips thereof and only partially through the corrugated band to define side-by-side strips of such band joined together at the peaks of the corrugations. The junctures form fold lines extending longitudinally of the packing material about which, upon erection of the pack, transversely adjacent regions provide mutually inclined walls defining pockets to receive the articles.
