Description

La présente invention concerne un procédé d'obtention d'un conteneur souple jetable après usage pour le conditionnement de produits stériles nécessitant une grande pureté, notamment de produits pharmaceutiques semi-ouvrés et le conteneur en ré­sultant.The present invention relates to a process for obtaining a flexible disposable container after use for the packaging of sterile products requiring high purity, in particular semi-worked pharmaceutical products and the resulting container.

Les produits pharmaceutiques sont actuel­lement stockés, entre les différentes phases de fa­brication et de conditionnement, dans des conteneurs en acier inoxydable. Ces conteneurs, au nombre de plusieurs centaines par usine, représentent un inves­tissement considérable. De plus , leur nettoyage obligatoire après chaque utilisation, nécessite des installations de lavage onéreuses lourde et coûteuse.Pharmaceutical products are currently stored, between the different phases of manufacturing and packaging, in stainless steel containers. These containers, several hundred in number per factory, represent a considerable investment. In addition, their mandatory cleaning after each use, requires expensive and heavy washing facilities.

La présente invention a pour objet de rem­placer ces conteneurs métalliques par un ensemble comprenant:
- un cadre métallique léger, éventuelle­ment démontable, sur lequel est suspendu
- un conteneur souple en toile polypropy­lène, jetable après usage.The object of the present invention is to replace these metal containers with an assembly comprising:
- a light metal frame, possibly removable, on which is suspended
- a flexible container in polypropylene fabric, disposable after use.

Le conditionnement proposé par la présente invention supprime l'entreposage de conteneurs lourds en acier inoxydable, leur nettoyage et divers con­trôles nécessaires. Il constitue un abaissement consi­dérable des coûts de production.The packaging proposed by the present invention eliminates the storage of heavy stainless steel containers, their cleaning and various necessary controls. It constitutes a considerable reduction in production costs.

En outre, un tel conditionnement est obtenu d'une façon simple qui assure une stérilité absolue du produit conditionné.In addition, such packaging is obtained in a simple manner which ensures absolute sterility of the packaged product.

Le conteneur selon la présente invention doit répondre à quatre exigences principales qui sont :
- propreté avant remplissage, et absence de risque de pollution du pollution du produit contenu pendant les opérations de remplissage, vidange et stockage;
- étanchéite : plusieurs niveaux possibles selon le matériau utilisé pour la poche intérieure;
- facilité de mise en place sur le cadre métallique et précision de positionnement sur ce ca­dre;
- contrôle de débit à la vidange et vidan­ge complète à chaque utilisation.The container according to the present invention must meet four main requirements which are:
- cleanliness before filling, and absence of risk of pollution from pollution of the product contained during filling, emptying and storage operations;
- sealing: several possible levels depending on the material used for the inner pocket;
- ease of installation on the metal frame and positioning accuracy on this frame;
- flow control on emptying and complete emptying at each use.

DE-A- 3 223 539 décrit et illustre un sac à grande contenance comportant des coutures latérales et des sangles de fermeture tant à la partie supé­rieure qu'à la partie inférieure. Ce sac ne comporte pas des fourreaux inférieurs et supérieurs de forme oblongue servant à le suspendre sur un cadre métal­lique comme dans la présente invention. Dans ce sac, il est prévu quatre sangles d'arrêt fixées sur des éléments de renforcement solidaires des parois du sac.DE-A- 3 223 539 describes and illustrates a large-capacity bag comprising side seams and closure straps both at the top and at the bottom. This bag does not include lower and upper sleeves of oblong shape used to hang it on a metal frame as in the present invention. In this bag, there are provided four stop straps fixed on reinforcing elements integral with the walls of the bag.

La présente invention propose donc un pro­cédé d'obtention d'un conteneur souple jetable après usage pour le conditionnement de produits stériles, notamment de produits pharmaceutiques semi-ouvrés qui est caractérisé en ce qu'il consiste en combinaison :

  • a) à découper deux bandes de toile identi­ques en forme de bouteille;
  • b) à confectionner une poche de forme ana­logue à celle des deux bandes de toile;
  • c) à coller ladite poche qui comporte une soudure étanche à chaque extrémité sur la surface de chacune desdites deux bandes de toile;
  • d) à coudre sur chaque bande de toile deux fourreaux de forme oblongue afin que l'espace délimi­té entre les deux fourreaux supérieurs et les deux fourreaux inférieurs constitue après assemblage des­dites deux bandes de toile un corps de forme cubi­que;
  • e) à assembler les deux bandes de toile par deux coutures verticales symétriquement opposées, la partie sous les deux fourreaux inférieurs consti­tuant une trémie en forme de tronc de cône terminé par un orifice fermé par une sangle tandis que la partie au-dessus des deux fourreaux supérieurs qui est définie à partir des coutures desdits fourreaux supérieurs constitue une jupe pourvue en bout d'un orifice et munie d'une sangle pour la fermeture après remplissage;
  • f) à plier à plat ledit conteneur de façon telle que les deux orifices soient à l'intérieur du pliage.
The present invention therefore provides a method for obtaining a flexible disposable container after use for the packaging of sterile products, in particular semi-worked pharmaceutical products, which is characterized in that it consists of a combination:
  • a) cutting two identical strips of canvas in the shape of a bottle;
  • b) to make a pocket similar in shape to that of the two strips of canvas;
  • c) gluing said pocket which has a sealed weld at each end on the surface of each of said two canvas strips;
  • d) sewing on each strip of canvas two oblong sheaths so that the space delimited between the two upper sheaths and the two lower sheaths constitutes after assembly of said two strips of canvas a body of cubic shape;
  • e) assembling the two strips of canvas by two symmetrically opposite vertical seams, the part under the two lower sleeves constituting a hopper in the form of a truncated cone terminated by an orifice closed by a strap while the part above the two sleeves upper which is defined from the seams of said upper sleeves constitutes a skirt provided at the end of an orifice and provided with a strap for closing after filling;
  • f) folding said container flat so that the two orifices are inside the fold.

La présente invention concerne également les caractéristiques ci-après considérées isolément ou selon toutes leurs combinaisons techniquement pos­sibles.The present invention also relates to the characteristics below considered in isolation or in all their technically possible combinations.

Le conteneur est suspendu tant avant rem­plissage que pendant la vidange sur un cadre métal­lique léger par l'intermédiaire de barres insérées dans les fourreaux, lesquelles barres sont assujet­ties par tout moyen approprié à des montants verti­caux dudit cadre;
- le cadre métallique léger est démontable;
- la section de l'orifice de vidange varie en fonction du débit désiré;
- tant les deux coutures verticales que les coutures des fourreaux, sont réalisées en fil poly­ester et sont coupées à chaud;
- les bandes de toile sont en polypropy­lène;
- la poche interne est en polyéthylene.The container is suspended both before filling and during emptying on a light metal frame by means of bars inserted in the sleeves, which bars are secured by any appropriate means to vertical uprights of said frame;
- the light metal frame is removable;
- the section of the drain orifice varies according to the desired flow;
- both the vertical seams and the sheath seams, are made of polyester thread and are hot cut;
- the canvas bands are made of polypropylene;
- the internal pocket is made of polyethylene.

Divers avantages et caractéristiques de la présente invention ressortiront de la description détaillée ci-après faite en regard des dessins anne­xés sur lesquels :

  • - la figure 1 est une représentation sché­matique des divers éléments constitutifs du conte­neur avant assemblage;
  • - la figure 2 est une vue en perspective du conteneur suspendu sur un cadre métallique pendant la vidange;
  • - la figure 3 est une vue en perspective du conteneur à l'état rempli.
Various advantages and characteristics of the present invention will emerge from the detailed description below made with reference to the appended drawings in which:
  • - Figure 1 is a schematic representation of the various components of the container before assembly;
  • - Figure 2 is a perspective view of the container suspended on a metal frame during emptying;
  • - Figure 3 is a perspective view of the container in the filled state.

Aux dessins annexés où les mêmes symboles de référence désignent des parties analogues, le con­teneur souple selon la présente invention est désigné dans son ensemble par 1. Le conteneur 1 est composé d'une enveloppe externe réalisée à partir de deux bandes de toile 2, 3 et d'une enveloppe interne 4 sous la forme d'une poche dont le matériau est choisi en fonction du degré d'étanchéité souhaité. Les deux bandes de toile 2, 3 sont découpées comme représenté sur la figure 1 selon une forme de bouteille. Ces bandes de toile 2, 3 comportent chacune deux four­reaux 7, 8, 9, 10 rapportés par couture qui serviront à la suspension du conteneur 1 sur un cadre métalli­que 22 muni de montants verticaux 24 au moyen de bar­res métalliques 23. Grâce à un tel agencement, la mise en place du conteneur est effectuée très rapide­ment. En outre, du fait de la prévision des deux fourreaux inférieurs 9, 10, le conteneur 1 ne dé­forme pas au cours du remplissage et conserve donc une forme cubique dans sa partie supérieure. Les cou­tures des deux fourreaux supérieurs 7, 8, sont réali­sées de manière à matérialiser le haut du conteneur 1 et délimiter les parties 20 qui munies d'une sangle 22 serviront de jupe pour la fermeture du conteneur 1 après remplissage. La poche 4 est, à titre d'exemple, une poche en polyéthylène. Elle assure l'étanchéité du conteneur 1 et est découpée en forme de bouteille. Sa largeur est quelque peu supérieure à celle des bandes de toile 2, 3 et elle comporte une soudure étanche 5, 6 à chaque extrémité. Lors de la mise en oeuvre du conteneur 1, la poche 4 est collée sur cha­cune des bandes de toile 2, 3. La partie interne de la poche 4 reste ainsi à l'abri de tout contact avec les poussières jusq'au moment de son ouverture pour le remplissage.In the accompanying drawings in which the same reference symbols designate similar parts, the flexible container according to the present invention is generally designated by 1. The container 1 is composed of an external envelope made from two strips of fabric 2, 3 and an internal envelope 4 in the form of a pocket, the material of which is chosen as a function of the desired degree of tightness. The two strips of fabric 2, 3 are cut as shown in Figure 1 in a bottle shape. These strips of fabric 2, 3 each comprise two sleeves 7, 8, 9, 10 added by sewing which will be used to suspend the container 1 on a metal frame 22 provided with vertical uprights 24 by means of metal bars 23. Thanks to such a arrangement, the positioning of the container is carried out very quickly. In addition, due to the forecast of the two lower sleeves 9, 10, the container 1 does not deform during filling and therefore retains a cubic shape in its upper part. The seams of the two upper sleeves 7, 8 are made so as to materialize the top of the container 1 and delimit the parts 20 which provided with a strap 22 will serve as a skirt for closing the container 1 after filling. The pocket 4 is, for example, a polyethylene pocket. It seals the container 1 and is cut into a bottle. Its width is somewhat greater than that of the fabric strips 2, 3 and it includes a sealed weld 5, 6 at each end. When the container 1 is used, the bag 4 is glued to each of the fabric strips 2, 3. The internal part of the bag 4 thus remains protected from any contact with the dust until it is opening for filling.

Les deux bandes de toile 2, 3 sont assem­blées par deux coutures verticales 12, 13, la partie inférieure 14 constituant une trémie 15 en forme de tronc de cône terminée par un orifice de vidange cy­lindrique 16 fermé par une sangle 17. La section de la trémie 15 est calculée à volonté en fonction du débit désiré. Toutes les coutures 19 sont réalisées en fil polyester et sont coupées à chaud, de manière à éviter tout risque de pollution du produit contenu par des fibrilles qui pourraient se détacher des fils.The two strips of fabric 2, 3 are assembled by two vertical seams 12, 13, the lower part 14 constituting a hopper 15 in the form of a truncated cone terminated by a cylindrical emptying orifice 16 closed by a strap 17. The section of the hopper 15 is calculated at will according to the desired flow rate. All the seams 19 are made of polyester thread and are cut hot, so as to avoid any risk of pollution of the product contained by fibrils which could detach from the threads.

Le conteneur terminé est plié à plat de telle sorte que ses deux orifices 16, 21 sont à l'in­térieur du pliage, ce qui évite ainsi tout risque d'entrée de poussières entre l'enveloppe externe cons­tituée par les bandes de toile 2, 3 et la poche in­terne 4. Etant donné que la poche interne 4 est sou­ dée à ses deux extrémités, elle ne peut pas être dé­ployée du fait de l'absence d'air à l'intérieur. En outre, étant donné que la poche est collée sur les côtés du conteneur 1, celui-ci ne peut pas non plus être déployé.The finished container is folded flat so that its two orifices 16, 21 are inside the fold, which thus avoids any risk of entry of dust between the external envelope constituted by the strips of fabric 2, 3 and the internal pocket 4. Since the internal pocket 4 is sou given at its two ends, it cannot be deployed due to the absence of air inside. In addition, since the pocket is glued to the sides of the container 1, it also cannot be deployed.

L'opération d'ouverture du conteneur ne pourra être exécutée que dans l'atelier de fabrica­tion de l'utilisateur, à l'abri de toute poussière au moment de la mise en place du conteneur 1 sur son ca­dre 22. L'ouverture ne sera possible qu'après avoir coupé la partie supérieure soudée de la poche 4. Il en sera de même pour la partie inférieure au moment de la vidange. Le conteneur selon la présente inven­tion procure de nombreux avantages :
- une construction aisée et simple à par­tir de deux seuls panneaux de toile de tout le con­teneur comprenant le corps, la jupe de fermeture su­périeure, la trémie et l'orifice de vidange;
- une diminution sensible du nombre de coutures qui est un gage de propreté;
- une géométrie parfaite due à la présence dwes deux fourreaux inférieurs;
- une étanchéité totale du fait de la réa­lisation de la poche interne totalement fermée jus­qu'à son ouverture pour le remplissage;
- un procédé de stockage intermédiaire beaucoup plus économique que les procédés selon l'art antérieur.The container opening operation can only be executed in the user's manufacturing workshop, protected from any dust when the container 1 is placed on its frame 22. The opening does not will be possible only after having cut the welded upper part of the pocket 4. It will be the same for the lower part at the time of emptying. The container according to the present invention provides numerous advantages:
- easy and simple construction from two single canvas panels of the entire container comprising the body, the upper closing skirt, the hopper and the drain opening;
- a significant reduction in the number of seams which is a guarantee of cleanliness;
- perfect geometry due to the presence of two lower sleeves;
- a total seal due to the realization of the internal pocket completely closed until its opening for filling;
- an intermediate storage process much more economical than the processes according to the prior art.
