Description

CONTENEUR EN CARTON PLASTIFIE AVEC BEC-VERSEUR SOUDE ET SON PROCEDE CONTAINER WITH CARDBOARD PLASTIFIE BEC-POURING SODA AND METHOD
DE FÂBRICÂTION. MANUFACTURING.

L'invention concerne les conteneurs à liquide formes à partir d'une feuille de carton ou similaire, eventuellement doublée d'une feuille d'aluminium, et plastifiez au moins sur sa face interieure pour permettre la réalisation de soudures etanches, ces conteneurs ayant une forme generale parallelepipedique refermée vers le haut apres remplissage par soudure et pliage d'un type approprie. The invention relates to liquid containers shapes from a cardboard sheet or the like, optionally lined with an aluminum foil, and laminate at least on its inner face to enable achieving watertight welds, the container having a generally parallelepiped shape closed upwardly after filling by welding and folding of a suitable type.

Pour faciliter itouverture de ces conteneurs, il est connu d'y pratiquer à l'avance un trou opercule dans leur partie supérieure, mais dans ce cas, pour eviter l'infiltration du liquide par la tranche du carton, il est en general necessaire que ltopercule, en plastique ou en aluminium, soit soude contre la face interieure du conteneur, cet opercule étant destine à être transperce ensuite l'aide d'un instrument quelconque ou d'un embout special à partie intérieure coulissante assurant le percement de cet. To facilitate itouverture of these containers, it is known to practice it in advance a cap hole in the upper part, but in this case, to avoid infiltration of liquid through the edge of the box, it is necessary that General ltopercule, plastic or aluminum, or sodium hydroxide against the inner face of the container, this cap being intended to then be ran using any instrument or special tip sliding inner part providing the piercing this. opercule, comme decrit par exemple dans le brevet américain 4 483 464.Toutefois une telle téalisation est relativement complexe par le fait qu'elle necessite une soudure d'opercule à l'intérieur de l'emballage, qu'elle necessite en outre l'utilisation d'un carton plastifie egalement sur sa face exterieure pour la soudure de la partie fixe de embout, et qu'elle necessite enfin une partie interieure mobile de dechirage en plus de la partie fixe et du capuchon de refermeture de cet embout. seal, as described for example in U.S. Patent 4 483 464.Toutefois such téalisation is relatively complex in that it requires a cap weld within the package, it requires further the use of a cardboard also plasticised on its outer face for welding to the fixed part of endpiece, and it finally requires a mobile interior part of tear in addition to the fixed part and the reclosure cap of this nozzle. Par suite- la fabrication et la mise en place d'un tel bec-verseur est relativement onereuse. For more- manufacture and installation of such a pouring spout is relatively expensive.

Le but de l'invention est d'eliminer les inconvénients precedents en simplifiant la fabrication du bec-verseur et sa mise en place, tout en garantissant une etancheite compiète pendant la conservation du conteneur. The object of the invention is to eliminate the foregoing disadvantages by simplifying the manufacture of the pouring spout and its implementation, while ensuring compiète tightness during storage of the container.

L'invention consiste a munir le bec-verseur d'une collerette sensiblement plane debordant au-delà de la section de la partie exterieure du bec et prolongee du côte intérieur par une courte partie annulaire destinée à traverser l'orifice pratique dans la paroi du conteneur, et à introduire ladite partie annulaire de ce bec verseur dans ledit orifice depuis l'exterieur du conteneur jusqu'a venir appliquer et souder cette collerette contre la couche plastifiée exterieure du conteneur The invention consists in providing the pouring spout with a substantially planar flange projecting beyond the section of the outer part of the beak and prolonged on the inside by a short annular part intended to pass through the orifice in the wall of container, and introducing said annular portion of the spout into said hole from outside the container to come apply and weld the flange against the outer plastic layer of the container
Pour assurer -la fois cette mise en place et cette soudure, le procede selon l'invention consiste a introduire dans ltextremite superieure -encore ouverte du conteneur, avant ou apres son remplissage, un mandrin de la section appropriee et comportant en face du trou du conteneur un evidement annulaire pour recevoir ladit partie annulaire du bec, puis a deplacer transversalement en direction de cet orifice et depuis l'exterieur une pièce de soudage comportant un evidement suffisant pour y loger la partie exterieure du bec et une extremite sensiblement plane sur laquelle s'appuie la face exterieure de la collerette, et ceci jusqu'a ce que la collerette vienne s'appuyer sur la paroi du conteneur, elle demie appuyée sur le mandrin, la pièce de soudage étant agencée pour permettre le soudage de la collerette sur la paroi par application de -chaleur et de pression en coopération avec le mandrin intérieur. -the time to ensure that setting up and this welding, the process according to the invention consists in introducing into upper ltextremite -still open container before or after filling, a mandrel of the appropriate section and having opposite the hole container an annular recess for receiving ladit annular portion of the spout and then move transversely in the direction of this orifice and from the outside a welding part having a recess sufficient to accommodate the outer part of the beak and one end substantially planar on which s 'supports the outer face of the flange, and this until the flange comes to bear on the container wall, the half supported on the mandrel, the sealing part being arranged to allow the welding of the flange on the -Heat wall by application of pressure and in cooperation with the inner mandrel.

En particulier la courte partie annulaire peut être d'une longueur suffisante, et ledit évidement annulaire être conforme en contre bouterolle pour assurer simultanément aux opérations qui précèdent l'épanouissement de cette courte partie annulaire radialement vers l'extérieur et le soudagè de celle-ci également contre la face intérieure plastifiée de la paroi du conteneur alentour dudit orifice. In particular the short annular portion may be of sufficient length, and said annular recess conform in riveting against to simultaneously ensure that operations that precede the development of this short annular part radially outwardly and welding thereof also against the inside plastic of the wall of the container surrounding said orifice.

D'autres particularités de l'invention apparattront dans la description qui va suivre d'un mode de réalisation pris comme exemple et représenté sur le dessin annexé sur lequel Other features of the invention apparattront in the description which follows of an embodiment given as example and shown in the accompanying drawing in which
la figure 1 est une coupe perpendiculaire a l'axe du conteneur et du mandrin au niveau de l'axe du bec-verseur; Figure 1 is a section perpendicular to the axis of the container and the mandrel at the level of the axis of the pouring spout;
la figure 2 est une vue correspondant la figure 1 apres opération de soudage, Figure 2 is a view corresponding figure 1 after welding operation,
On voit sur les figures le conteneur 1 dans la paroi duquel est découpé un orifice dans l'axe du bec verseur 2 lequel comporte une partie extérieure 3 de type approprié, et de préférence refermée par un opercule déchirable 4 de type connu. It is seen from FIGS container 1 in the wall of which is cut a hole in the axis of the spout 2 which has an outer portion 3 of suitable type, and preferably closed by a tear-off cap 4 of known type.

Conformément a l'invention, ce bec-verseur est mani d'une collerette 5 sensiblement plane débordant au-del de la section du trou, et une courte partie annulaire 6 prolongeant la partie extérieure 3 vers l'intérieur de l'orifice. According to the invention, this pouring spout is mani a substantially flat flange 5 projecting beyond the section of the hole, and a short annular part 6 extending the outer portion 3 towards the inside of the orifice.

Pour poser ce bec-verseur sur le conteneur 1 préalablement muni de son orifice, on introduit dans le conteneur 1 un mandrin 7 d'une section appropriée et qui est muni du côté de ltorifice d'un évidement annulaire 8 destiné a recevoir la partie annulaire 6. To ask this pouring spout on the container 1 previously provided with its orifice is introduced into the container 1 a collet 7 of a suitable section and which is provided with the ltorifice side with an annular recess 8 for receiving the annular portion 6.

Ensuite on approche transversalement en direction de l'orifice une pièce de soudage 9 munie d'un évidement 10 suffisant pour recevoir la partie extérieure 3 du bec-verseur 2, et munie également d'une extrémité 11 sensiblement plane destinée à servir d'appui pour la collerette 5 du bec-verseur 2 placé au préalable sur cette piece de soudage 9. Then transversely approach towards the hole a welding part 9 provided with a recess 10 sufficient to receive the outer part 3 of pouring spout 2, and also provided with a substantially flat end 11 intended to serve as a support for the flange 5 of the pouring spout 2 placed beforehand on this welding part 9.

Le déplacement transversal de la pièce 9 continue jusqu a ce que la partie annulaire 6 pénetre par l'orifice de la paroi du conteneur et que la collerette 5 vienne s'appuyer sur la face extérieure de la paroi du conteneur, elle-m#me en appui sur le mandrin 7. The transverse displacement of the part 9 continues up was that the annular part 6 penetrates through the hole in the container wall and the collar 5 comes to bear on the outer face of the container wall, which is # m me supported on the mandrel 7.

La pièce de soudage 9 peut alors entrer en action pour exercer un chauffage et une pression propres assurer le soudage de la collerette 5 sur la face extérieure du conteneur. The welding part 9 may then go into action to perform heating and pressure own ensure the welding of the flange 5 on the outer face of the container. Ce chauffage peut avoir lieu par effet thermique ordinaire, ou par ultrason, ou encore par haute fréquence électrique en coopération également avec le mandrin 7, lequel peut avantageusement être irnini d'un moyeu derefroidissement. This heating can take place by ordinary thermal effect, or by ultrasound or by high-frequency electric also in cooperation with the mandrel 7, which may advantageously be a Irnini derefroidissement hub.

Pour certains types de carton, ou certains liquides peu pénétrants tels que du lait, où la protection de la tranche du carton le long du bord -de l'orifice n'est pas nécessaire, la partie annulaire peut avoir une saillie limitée enviroh ltepaisseur du carton.Toutefois dans le cas le plus général, où l'on désire protéger la tranche du carton contre l'infiltration du liquide transporté dans le conteneur, on peut avantageusement donner a la partie annulaire 6 une longueur suffisante, et conformer l'évidement annulaire 8 pour former contre bouterollej afin que l'opération de soudage indiquée précédemment produise en même temps l'épanouissement radialement vers l'extérieur de la partie annulaire 6, et sa fusion assurant le soudage du bec également sur la surface intérieure plastifiée du conteneur I alentour de l'orifice. For some types of paperboard, or some little penetrating liquids such as milk, where the protection of the edge of the carton along the -from the orifice edge is not necessary, the annular part may have a limited projection of enviroh ltepaisseur carton.Toutefois in the most general case, where it is desired to protect the edge of the cardboard against the infiltration of the liquid transported in the container, can advantageously give the annular portion 6 has a sufficient length, and comply with the annular recess 8 to form against bouterollej so that the welding operation indicated above occur at the same time the radially outward growth of the annular portion 6, and its melting ensuring the spout welding also on the plastic interior surface of the container surrounding I of the orifice.

Le bec-verseur selon l'invention est donc extrêmement économique et d'une pose extrêment simple et rapide, et cette pose peut indifféremment avoir lieu lors de le construction du conteneur, - le mandrin 7 pouvant alors avantageusement être celui utilisé pour la formation du fond ferme, ou encore apres remplissage, le mandrin 7 étant alors limité en longueur pour se placer juste au-dessus du liquide dans le conteneur et assurer la pose du bec juste avant la soudure de fermeture supérieure du conteneur. The pouring spout according to the invention is extremely economical and an extremely simple and rapid, and this pose can either take place during the construction of container - the chuck 7 can advantageously be used for training firm bottom, or after filling, the mandrel 7 is then limited in length to be placed just above the liquid in the container and ensure the installation of the spout just before the welding upper closure of the container.
