Title (EN) ARRANGEMENTS IN A PRESSING APPARATUS FOR FOLDING CARDBOARD BOXES AND CONTAINERS, AS WELL AS USE OF SUCH A PRESSING APPARATUS
(FR) DISPOSITIF PRESSEUR PERMETTANT DE PLIER DES BOITES ET DES RECIPIENTS EN CARTON, ET UTILISATION DUDIT DISPOSITIF
Abstract:
(EN) The invention relates to a folding method for empty disposable packages, e.g. milk cartons, permitting reuse collection in suitable physical standards, as well as a device for this purpose. By using a device consisting of a frame member's bottom plate (3) firmly cooperating with two longitudinal, upright, identical strings (4), one at each side, between which a pressing plate (1) is led downwardly, the opening portion of an empty milk carton placed beneath said pressing face between the strings with a glued bottom orle orientated vertically, will be closed first. Air within the carton will be compressed and exert an internal pressure against i.a. the bottom side, which will be blasted outwardly and deformed to a single-walled and triangular point, before the air escapes through the opening. The thickness of such a compressed carton allows twenty empty cartons to be inserted into one, which is 50 % more than normal. The pressing plate (1) of the device is hinged between the lower and outer part of the strings (4), so that a directed pressure against the handle (5) of the pressure plate (1) will do the folding function.
(FR) L'invention concerne un procédé permettant de plier des emballages jetables vides, tels que des cartons à lait, de façon à les récupérer avec des normes physiques appropriées en vue de leur recyclage, ainsi qu'un dispositif destiné audit procédé. Le dispositif comprend une plaque de fond (3) faisant partie d'un élément cadre, qui coopère fermement avec deux rebords (4) identiques verticaux allongés longitudinalement, un de chaque côté, entre lesquels descend une plaque presseuse (1). Le dispositif ferme d'abord la partie ouverture d'un carton à lait vide placé sous ladite face presseuse entre les rebords, avec le joint collé du fond orienté verticalement. L'air contenu dans le carton étant compressé, il exerce une pression interne notamment contre le fond, qui gonfle vers l'extérieur et se déforme de façon à former un triangle constitué d'une seule paroi, puis il s'échappe par l'ouverture. L'épaisseur du carton ainsi comprimé permet d'insérer vingt cartons vides dans un seul, ce qui est égal à une fois et demi la normale. La plaque presseuse (1) du dispositif est articulée à la partie inférieure externe des rebords (4), de façon qu'une pression appliquée sur la poignée (5) de la dite plaque effectue le pliage.
