Abstract
Description
La présente invention concerne une boîte d'isolation de l'atmosphère ambiante pour traitement de produits en vrac ou pré-conditionnés en emballages à sceller, comportant un corps de boîte et une paroi mobile déplaçable entre une position d'ouverture et une position de fermeture où elle coopère à fermeture étanche avec le corps de boîte. Une telle boîte est enseignée par US-A-2 790 284.The present invention relates to a box for isolating the ambient atmosphere for the treatment of bulk or pre-conditioned products in sealed packages, comprising a box body and a movable wall movable between an open position and a closed position. where it cooperates tightly with the box body. Such a box is taught by US-A-2,790,284.
Dans un type de ces boîtes, c'est le couvercle de boîte qui constitue la porte d'accès et forme le moyen obturateur, en prévoyant pour le couvercle de boîte, une position de pré-fermeture et des moyens qui le font passer de ladite position de pré-fermeture à la position de fermeture étanche sous l'effet d'une action de pression exercée de l'extérieur en direction dudit couvercle.In one type of these boxes, it is the box cover which constitutes the access door and forms the shutter means, providing for the box cover, a pre-closing position and means which make it pass from said pre-closing position to the sealed closing position under the effect of a pressure action exerted from the outside towards said cover.
La présente invention a pour objet de perfectionner ce type de boîte d'isolation pour la rendre de réalisation plus simple et moins onéreuse et de manipulation plus aisée et plus fiable.The object of the present invention is to improve this type of insulation box to make it simpler and less expensive to produce and easier and more reliable to handle.
Pour ce faire, selon une caractéristique de l'invention, la paroi mobile comprend au moins une ouverture agencée pour recevoir un bouchon comportant une tête, une partie de corps adjacente à la tête et une partie d'extrémité comportant au moins un passage interne, le bouchon étant déplaçable dans l'ouverture entre une position d'enfoncement partiel, où la partie d'extrémité est engagée dans l'ouverture, et une position de fermeture, où la partie de corps coopère en engagement étanche avec l'ouverture, sous l'effet de l'application sur la tête d'une force pour amener la paroi mobile dans sa position de fermeture.To do this, according to a characteristic of the invention, the movable wall comprises at least one opening arranged to receive a plug comprising a head, a body part adjacent to the head and an end part comprising at least one internal passage, the plug being movable in the opening between a partial insertion position, where the end part is engaged in the opening, and a closed position, where the body part cooperates in sealed engagement with the opening, under the effect of the application on the head of a force to bring the movable wall into its closed position.
La présente invention a également pour objet un procédé de traitement de produits dans une enceinte de traitement sous vide au moyen d'une boîte d'isolation du type défini ci-dessus, où la paroi mobile est un couvercle de la boîte, laquelle comporte un joint d'étanchéité périphérique, comprenant les étapes suivantes : la boîte renfermant les produits est placée dans l'enceinte avec le couvercle en position de fermeture en appui sur le joint d'étanchéité et le bouchon en position d'enfoncement partiel ; une fois l'opération de traitement sous vide effectuée, on applique sur le bouchon la force pour isoler la boîte ; puis on rétablit une pression dans l'enceinte.The present invention also relates to a process for treating products in a vacuum treatment enclosure by means of an insulation box of the type defined above, where the movable wall is a cover of the box, which comprises a peripheral seal, comprising the following steps: the box containing the products is placed in the enclosure with the cover in the closed position resting on the seal and the plug in the partially depressed position; once the vacuum treatment operation has been carried out, force is applied to the stopper to isolate the box; then a pressure is restored in the enclosure.
Dans l'agencement selon l'invention, on a différencié la fonction de couvercle ou porte d'accès, permettant la mise en place ou le retrait des emballages pré-conditionnés et la fonction de communication et d'isolation d'avec l'atmosphère extérieure permettant différentes opérations, telle une lyophilisation de produits, lorsque la communication est établie avec l'atmosphère extérieure, qui est alors celle d'une enceinte de traitement placée sous une atmosphère contrôlée, ou sous légère dépression, alors que l'opération de transfert vers un poste de conditionnement définitif d'une boîte contenant de tels emballages encore ouverts est assurée, préalablement à leur sortie d'enceinte de traitement, par une action obturatrice sur les bouchons, en fait un simple enfoncement final de ces bouchons, assurant ainsi le maintien de l'état des produits traités, en évitant de les mettre en présence d'une atmosphère humide et/ou oxydante et/ou, le cas échéant, empêchant toute interaction desdits produits, s'ils sont toxiques, sur les opérateurs et/ou avec l'atmosphère environnante.In the arrangement according to the invention, the function of cover or access door has been differentiated, allowing the introduction or removal of pre-conditioned packaging and the function of communication and isolation from the atmosphere. exterior allowing various operations, such as freeze-drying of products, when communication is established with the exterior atmosphere, which is then that of a treatment enclosure placed under a controlled atmosphere, or under slight depression, while the transfer operation towards a final packaging station of a box containing such packages still open is ensured, prior to their exit from the treatment enclosure, by a sealing action on the plugs, in fact a simple final insertion of these plugs, thus ensuring the maintenance of the condition of the treated products, avoiding putting them in the presence of a humid and / or oxidizing atmosphere and / or, if necessary, preventing nt any interaction of said products, if they are toxic, on operators and / or with the surrounding atmosphere.
Les caractéristiques et avantages de l'invention ressortiront d'ailleurs de la description qui suit, à titre d'exemple en référence aux dessins annexés sur lesquels :
- la figure 1 est une vue en coupe d'une boîte selon l'invention en communication avec l'atmosphère de traitement ;
- la figure 2 est une vue partielle de cette même boîte en position d'isolation d'une atmosphère environnante.
- Figure 1 is a sectional view of a box according to the invention in communication with the treatment atmosphere;
- Figure 2 is a partial view of the same box in the isolation position of a surrounding atmosphere.
En se référant aux dessins annexés, une boîte comporte un corps de boîte 2 avec un couvercle 3 qui peut venir en position de fermeture étanche, telle que représentée aux dessins, en coopération avec un joint d'étanchéité périphérique 4 porté par le corps de boîte 2. Le couvercle de boîte 3 comprend une ou plusieurs ouvertures de forme circulaire, au travers de chacune desquelles peut s'engager un bouchon 6 en un matériau plastique souple ayant une structure particulière, à savoir une tête plate 7, un corps avec une partie d'extrémité 8 éloignée de la tête 6, qui est pourvue de dégagements en forme de fentes latérales formant passages internes 9, et une partie de corps 10 adjacente à la tête 7 qui peut s'engager à serrage dans l'ouverture 5 pour assurer l'étanchéité de l'intérieur de la boîte 1 d'une atmosphère environnante. Un petit épaulement 11 permet à l'opérateur d'engager un bouchon 7 dans une position d'enfoncement partiel correcte assurant la communication entre l'intérieur de la boîte 1 par rapport à l'atmosphère de traitement.Referring to the accompanying drawings, a box comprises a box body 2 with a cover 3 which can come in a sealed closure position, as shown in the drawings, in cooperation with a peripheral seal 4 carried by the box body. 2. The box cover 3 comprises one or more openings of circular shape, through each of which can be engaged a
Cette boîte reçoit au départ, couvercle 3 enlevé, du produit en vrac ou dans une pluralité d'emballages 12, tels des ampoules, ouverts en 13 et renfermant des produits à traiter dans une atmosphère de traitement spéciale, par exemple par lyophilisation. Ces emballages 12, qui ici ont été représentés sous forme d'ampoules à sceller, sont placés côte à côte dans un réceptacle 14 à paroi latérale 15.This box receives at the start, cover 3 removed, in bulk or in a plurality of
La boîte 1 ainsi pourvue des emballages 12, avec les bouchons 7 en position de semi-ouverture et le couvercle 3 en position de fermeture en contact sur le joint 4, comme représenté à la figure 1, est introduite dans une enceinte de traitement dont on voit une paroi d'étagère inférieure 17 et une paroi supérieure 18 qui ici est prévue avec mobilité dans le sens vertical FF', avec un débattement au moins égal à la course de translation nécessaire pour déplacer un bouchon 7 de la position de semi-ouverture telle que représentée à la figure 1 à une position d'obturation complète telle que représentée à la figure 2. Une fois l'opération de traitement sous vide effectuée, dans la configuration de la figure 1, la paroi 18 est abaissée dans la configuration de la figure 2, en enfonçant ainsi les bouchons 7 et en isolant donc l'intérieur de la boîte de l'atmosphère environnante. En rétablissant la pression atmosphérique dans l'enceinte, le couvercle 3 demeure plaqué sur le joint 4 en raison du vide régnant dans la boîte 1. Dans cette dernière configuration, la boîte d'isolation 1 peut, à la fin du traitement, être ainsi extraite de l'enceinte et transférée à un poste de conditionnement définitif, où l'on procède alors au scellement étanche des emballages 12, ou simplement stockée sans précaution spéciale quant à l'atmosphère environnante. L'ouverture ultérieure du couvercle 3 est effectuée en cassant le vide dans la boîte 1 en retirant ou simplement en soulevant un au moins des bouchons 7 pour dégager les passages 9.The box 1 thus provided with the
Dans le cas d'application à la lyophilisation, on procède d'une façon plus adaptée en ce sens qu'à la fin d'une opération de lyophilisation, où le lyophilisateur est encore sous vide, on casse d'abord le vide dans l'enceinte du lyophilisateur par un gaz inerte ou de l'air, jusqu'à une pression absolue d'environ 0,8 bar (0,2 bar de dépression), on procède à l'obturation par déplacement des bouchons 7, on casse le vide dans l'enceinte de lyophilisation jusqu'à équilibre avec l'atmosphère, tout en conservant la force d'application obturatrice F′ sur les bouchons, puis on libère ladite force, de sorte que le couvercle 3 est maintenu sur le joint 4 par la dépression résiduelle interne au boîtier 1. Afin de récupérer les produits en vrac ou conditionnés, il suffit alors, comme vu plus haut, de procéder au soulèvement d'un bouchon, ce qui fait disparaître la dépression interne de sorte que le couvercle peut être levé sans difficulté.In the case of application to lyophilization, the procedure is more suitable in this sense that at the end of a lyophilization operation, where the lyophilizer is still under vacuum, the vacuum is first broken in the '' freeze-dryer enclosure by inert gas or air, up to an absolute pressure of about 0.8 bar (0.2 bar of depression), the obturation is carried out by displacement of the
L'invention s'applique à différentes techniques de traitement de produits dans des emballages de pré-conditionnement, par exemple la lyophilisation, de façon à protéger les produits ainsi traités de l'atmosphère environnante et/ou les opérateurs d'effets nocifs de produits toxiques, et cela pendant tout le temps où lesdits emballages ne sont pas fermés de façon étanche, que ce soit le transfert vers le poste de traitement intermédiaire ou plus généralement tout stockage d'attente.The invention applies to different techniques for treating products in preconditioning packaging, for example lyophilization, so as to protect the products thus treated from the surrounding atmosphere and / or operators from harmful effects of products. toxic, and this during the entire time when said packages are not sealed, whether it is transfer to the intermediate processing station or more generally any standby storage.
