Abstract (en)

[origin: US4621484A] 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. While it is hot the longer and narrower wave blank, bent into waves, is glued on, leaving the edge portion of the wider blank with spaced cross-ribbons of adhesive which are allowed to cool so that they are no longer sticky. The glued blanks are then filled at a packing station but before they are folded to make pockets, for the eggs, the free edge strip is heated with hot air to soften the adhesive ribbons and then the box is set up and filled and after the top of the box is folded into place, the overlapping free edge strip is pressed against the underlying cover strip to stick the two together. When the adhesive has cooled the pack is secured.

Abstract (de)

Die aus fünf durch Biegekanten (13) zusammengehaltenen Stützbahnen bestehende Verpackung ist entlang der Trennfuge (14) im aufgerichteten Zustand zu fixieren. Hiezu dienen Klebstoffauftragungen (24) die zuvor auf einem vorstehenden Randstreifen (22) beim Verkleben des Wellenbandes mit dem Deckband aufgebracht wurden. Diese nur heiss klebenden Klebstoffauftragungen (24) werden nach dem Einfüllen der Eier (28) erwärmt, bevor der Randstreifen (22) über das Deckband der benachbarten Stützbahn (20) gelegt und mit diesem verklebt wird.
