Description

La présente invention concerne un dispositif de stockage étanche d'au moins un produit sensible à l'humidité, tel qu'un catalyseur à base d'un isocyanate pour préparer une colle ou un joint d'étanchéité de type polyuréthanne mono ou bi-composants, et un procédé pour stocker ledit(s) produit(s) d'une manière étanche à l'intérieur d'un container de stockage rigide. L'invention s'applique notamment au stockage de catalyseurs pour des mastics de type polyuréthanne bi-composants destinés au scellement de vitrages isolants.The present invention relates to a device for the sealed storage of at least one moisture-sensitive product, such as an isocyanate-based catalyst, for preparing a one-component or two-component polyurethane glue or sealant. and a method for storing said product (s) in a sealed manner within a rigid storage container. The invention is particularly applicable to the storage of catalysts for two-component polyurethane type sealants for sealing insulating glass units.

Pour le stockage et le transport étanches de produits sensibles à l'humidité, il est connu d'utiliser un dispositif comportant un fût métallique et un sac plastique étanche à l'eau à ouverture totale qui est destiné à recevoir ces produits et qui est disposé à l'intérieur de ce fût. On ferme usuellement ce sac au moyen d'une bague ou d'un câble de fermeture qui rassemblent les bords de cette ouverture en les déformant par torsion. On se reportera par exemple aux documents de Brevet US-A-3 358 905 et US-A-2 748 673 pour une description de tels dispositifs de stockage.For the waterproof storage and transport of moisture-sensitive products, it is known to use a device comprising a metal drum and a full-opening watertight plastic bag which is intended to receive these products and which is arranged. inside this barrel. This bag is usually closed by means of a ring or a closure cable which gather the edges of this opening by deforming them by twisting. Reference is made, for example, to US Pat. No. 3,358,905 and US Pat. No. 2,748,673 for a description of such storage devices.

Les catalyseurs à base d'un isocyanate servant à préparer des colles ou des joints d'étanchéité de type polyuréthanne sont des produits visqueux qui sont extrêmement sensibles à l'humidité et qui nécessitent de ce fait des précautions de scellage toutes particulières. Actuellement, ces catalyseurs sont stockés et expédiés comme suit, en référence aux figures 1 à 5 ci-jointes.Isocyanate catalysts for preparing polyurethane glues or seals are viscous products that are extremely sensitive to moisture and thus require special sealing precautions. Currently, these catalysts are stored and shipped as follows, with reference to Figures 1 to 5 attached.

Comme illustré à la figure 1, on dispose un sac intérieur de garnissage 1 étanche à l'eau, à ouverture totale et de volume variable sur la face interne de la paroi d'un container métallique de remplissage 2, de sorte que l'ouverture du sac 1 coïncide avec celle du container 2 et que les bords 1a de cette ouverture soient rabattus sur la face externe de ladite paroi. On effectue ensuite le remplissage du sac 1, par exemple par déversement direct du catalyseur 3 dans ce dernier (voir flèche A).As illustrated in FIG. 1, there is disposed a watertight, completely open and variable volume inner lining bag 1 on the internal face of the wall of a metal filling container 2, so that the opening of the bag 1 coincides with that of the container 2 and that the edges 1a of this opening are folded on the outer face of said wall. The bag 1 is then filled, for example by direct pouring of the catalyst 3 into the latter (see arrow A).

Une fois ce remplissage terminé, on procède à la fermeture du sac 1 comme illustré à la figure 2, en rabattant mutuellement vers l'intérieur les bords 1 a de son ouverture, en les rassemblant puis en appliquant sur les bords ainsi rabattus et rassemblés un ruban adhésif 4.Once this filling is completed, the bag 1 is closed as illustrated in FIG. 2, by folding the edges 1a of its opening inwardly, bringing them together and then applying on the folded and assembled edges a adhesive tape 4.

On retourne ensuite le sac 1 ainsi fermé et on le dispose à l'état retourné dans un autre container métallique de stockage 5, comme illustré à la figure 3, pour limiter les risques de pénétration d'humidité à travers le ruban adhésif 4. Le ruban 4 et le fond 1 b du sac 1 se trouvent alors respectivement en regard du fond du container 5 et d'un couvercle 5a venant obturer ce dernier. On expédie en clientèle ce container 5 obturé contenant le sac 1 ainsi fermé et retourné.The bag 1 thus closed is then returned and it is disposed in the returned state in another metallic storage container 5, as illustrated in FIG. 3, to limit the risks of penetration of moisture through the adhesive tape 4. ribbon 4 and the bottom 1b of the bag 1 are then respectively facing the bottom of the container 5 and a lid 5a closing the latter. This closed container 5 containing the bag 1 thus closed and returned is shipped to the customer.

Comme illustré à la figure 4, le client utilisateur du catalyseur 3, après avoir ôté le couvercle 5a du container 5, pratique une découpe 6 en forme de rondelle (représentée en pointillés) sur le fond 1b du sac 1 puis, comme illustré à la figure 5, il y dispose un appareillage d'enduction comportant un plateau « suiveur » 7 qui est appliqué sur le fond 1 b en coulissant à l'intérieur du container 5 et qui se prolonge verticalement en son centre par une conduite d'évacuation 8 communiquant avec le catalyseur 3 du fait de la découpe 6. L'utilisateur procède à l'évacuation du catalyseur 3 en exerçant une pression vers le bas (voir flèches B) sur ce plateau 7, de sorte à entraîner le catalyseur 3 vers le haut (voir flèche C) en direction d'une unité de fabrication pour préparer les colles ou les joints précités.As illustrated in FIG. 4, the user of the catalyst 3, after removing the lid 5a from the container 5, makes a washer-shaped cutout 6 (shown in dashed lines) on the bottom 1b of the bag 1 and, as illustrated in FIG. 5, there is a coating apparatus comprising a follower plate 7 which is applied to the bottom 1b by sliding inside the container 5 and which extends vertically in its center by a discharge pipe 8 communicating with the catalyst 3 because of the cutout 6. The user proceeds to the evacuation of the catalyst 3 by exerting a downward pressure (see arrows B) on this plate 7, so as to drive the catalyst 3 upwards (see arrow C) towards a manufacturing unit to prepare the adhesives or the aforementioned joints.

Un inconvénient majeur d'un tel procédé de stockage réside dans le retournement nécessaire du sac 1 lors de son transfert du container de remplissage 2 vers le container de stockage 5, en vue d'améliorer l'étanchéité du stockage. En effet, ce retournement peut provoquer une déchirure du sac 1, susceptible d'entraîner une cristallisation et une fuite du catalyseur 3, et il conduit à une opération de découpe du fond 1 b du sac 1 qui est malaisée, salissante et pouvant entraîner une perte de catalyseur 3, ce qui pénalise le coût de fabrication de ces colles ou de ces joints et nuit en outre à la préservation de l'environnement.A major drawback of such a storage method lies in the necessary reversal of the bag 1 during its transfer from the filling container 2 to the storage container 5, to improve the sealing of the storage. Indeed, this reversal can cause a tear of the bag 1, likely to cause crystallization and leakage of the catalyst 3, and it leads to a cutting operation of the bottom 1 b of the bag 1 which is difficult, messy and can lead to loss of catalyst 3, which penalizes the cost of manufacture of these glues or these joints and also harms the preservation of the environment.

De plus, le peu d'air emprisonné lors de la fermeture du sac 1 par le ruban adhésif 4, qui se retrouve au fond du container de stockage 2 suite à ce retournement, a tendance à migrer vers le haut du sac 1 sous la pression du plateau « suiveur » 7, ce qui peut nuire à la mise en oeuvre ultérieure du catalyseur 3 extrait du sac 1.In addition, the little air trapped during the closure of the bag 1 by the adhesive tape 4, which is found at the bottom of the storage container 2 following this reversal, tends to migrate upwards of the bag 1 under pressure of the "follower" plate 7, which can hinder the subsequent implementation of the catalyst 3 extracted from the bag 1.

Un autre inconvénient de ce procédé de stockage de catalyseur 3 réside dans le caractère inesthétique de ce ruban adhésif 4 appliqué sur les bords 1a de l'ouverture du sac 1.Another disadvantage of this catalyst storage method 3 lies in the unsightly nature of this adhesive tape 4 applied on the edges 1a of the opening of the bag 1.

Un but de la présente invention est de proposer un dispositif de stockage étanche d'au moins un produit sensible à l'humidité, tel qu'un catalyseur à base d'un isocyanate pour préparer une colle ou un joint d'étanchéité de type polyuréthanne mono ou bi-composants, ce dispositif comportant un container extérieur rigide à couvercle et un container intérieur souple et étanche à l'eau qui est destiné à recevoir ledit produit et qui est disposé à l'intérieur dudit container extérieur, le container intérieur présentant au moins une ouverture destinée à recevoir ce produit, ladite ouverture étant définie par un goulot qui est formé dans ledit container intérieur selon une section transversale prédéterminée et qui est apte à être scellé par rétrécissement de ladite section, qui remédie à cet inconvénient.An object of the present invention is to provide a device for the sealed storage of at least one moisture-sensitive product, such as an isocyanate-based catalyst for preparing a polyurethane-type glue or seal. single or two-component, this device comprising a rigid outer container with a lid and a flexible and watertight inner container which is intended to receive said product and which is disposed inside said outer container, the inner container having the at least one opening for receiving this product, said opening being defined by a neck which is formed in said inner container in a predetermined cross-section and which is adapted to be sealed by narrowing of said section, which overcomes this disadvantage.

Un dispositif de stockage 10 selon l'invention d'un ou de produit(s) étanche(s) à l'eau, tels que des catalyseurs à base d'un isocyanate pour préparer une colle ou un joint d'étanchéité de type polyuréthanne mono ou bi-composants est illustré dans sa totalité aux figures 8 à 12. Ce dispositif 10 se distingue essentiellement des dispositifs de stockage connus qui incorporent, en référence aux figures 1 à 5, le sac de garnissage 1 et les containers 2 et 5, en ce qu'il comporte un container intérieur souple 11 qui est illustré plus particulièrement à la figure 7.A storage device 10 according to the invention of a watertight product (s), such as isocyanate-based catalysts for preparing a polyurethane-type glue or seal mono or bi-component is illustrated in its entirety in Figures 8 to 12. This device 10 is essentially distinguished from known storage devices that incorporate, with reference to Figures 1 to 5, the packing bag 1 and the containers 2 and 5, in that it comprises a flexible inner container 11 which is illustrated more particularly in Figure 7.

Le container souple 11 est constitué dans cet exemple de réalisation d'une sache à base d'au moins un matériau étanche à l'eau qui présente une paroi latérale 12 et une ouverture 13 dont le bord supérieur est est défini par un goulot 14 pour permettre son remplissage. Le goulot 14 est formé par moulage d'un seul tenant avec la paroi latérale 12, de telle sorte que ce goulot 14 présente une section transversale prédéterminée, qui est adaptée pour recevoir un embout 15 d'un tuyau de remplissage 16 débouchant à l'intérieur du goulot 14, pour acheminer le produit à stocker dans le container 11 en le canalisant à l'intérieur du goulot 14.The flexible container 11 is constituted in this embodiment of a bag based on at least one watertight material which has a side wall 12 and an opening 13 whose upper edge is defined by a neck 14 for allow filling. The neck 14 is formed by integrally molding with the side wall 12, so that the neck 14 has a predetermined cross-section, which is adapted to receive a tip 15 of a filling pipe 16 opening to the inside the neck 14, for conveying the product to be stored in the container 11 by channeling it inside the neck 14.

Comme illustré à la figure 6, la paroi latérale 12 et le goulot 14 présentent avantageusement tous deux une géométrie cylindrique de section circulaire, et cette paroi 12 se prolonge d'une manière discontinue, radialement vers l'intérieur et sensiblement à angle droit, par un tronçon annulaire 17 qui se termine par la base inférieure 14b du goulot 14, de telle sorte que ce tronçon 17 soit sensiblement perpendiculaire à la paroi latérale 12 et au goulot 14. Dans cet exemple de réalisation, le tronçon annulaire 17 s'étend légèrement vers le haut (i.e. axialement vers l'extérieur du container 11) de la paroi latérale 12 au goulot 14.As illustrated in FIG. 6, the lateral wall 12 and the neck 14 advantageously both have a cylindrical geometry of circular cross-section, and this wall 12 extends in a discontinuous manner, radially inwards and substantially at right angles, through an annular section 17 which ends with the lower base 14b of the neck 14, such that this section 17 is substantially perpendicular to the side wall 12 and the neck 14. In this embodiment, the annular section 17 extends slightly upwards (ie axially towards the outside of the container 11) of the lateral wall 12 at the neck 14.

Le container 11 est avantageusement constitué d'un polyéthylène de basse densité (LDPE), de masse volumique par exemple égale à 0,922 g/cm3.The container 11 is advantageously made of a low density polyethylene (LDPE), density for example equal to 0.922 g / cm 3 .

Comme illustré à la figure 7, le goulot 14 est apte à être scellé par rétrécissement de sa section, dans cet exemple au moyen d'un organe de serrage mécanique 18, tel qu'un collier ou une agrafe, qui enserre le goulot 14 d'une manière étanche à l'eau axialement entre le bord supérieur 14a et la base inférieure 14b du goulot 14. On notera que ce goulot 14 pourrait également être scellé par soudage à chaud.As illustrated in Figure 7, the neck 14 is adapted to be sealed by shrinking its section, in this example by means of a mechanical clamping member 18, such as a collar or a staple, which encloses the neck 14 d In a water-tight manner axially between the upper edge 14a and the lower base 14b of the neck 14. It will be noted that this neck 14 could also be sealed by hot welding.

Comme illustré aux figures 8 à 12, le dispositif de stockage 10 selon l'invention se distingue en outre des dispositifs de stockage connus 1, 2 et 5 des figures 1 à 5, en qu'il comporte un seul et même container extérieur rigide 20. Ce dernier, avantageusement métallique, sert à la fois au remplissage et au stockage du produit 3 et il contient, en regard de sa paroi latérale 21, le container souple 11 selon l'invention. On notera que le container souple 11 présente un volume qui est adapté à celui du container rigide 20, de sorte que ce container souple 11 puisse épouser sensiblement la face interne de la paroi du container rigide 20 à la manière d'une doublure intérieure ou d'un garnissage.As illustrated in FIGS. 8 to 12, the storage device 10 according to the invention is further distinguished from the known storage devices 1, 2 and FIGS. 1 to 5, in that it comprises a single rigid outer container 20. The latter, advantageously metallic, serves both to fill and to store the product 3 and contains, opposite its side wall 21, the flexible container 11 according to the invention. Note that the flexible container 11 has a volume that is adapted to that of the rigid container 20, so that this flexible container 11 can substantially marry the inner face of the wall of the rigid container 20 in the manner of an inner liner or d a lining.

Le procédé de stockage et d'extraction selon l'invention du produit 3 est avantageusement mis en oeuvre de la manière suivante.The storage and extraction process according to the invention of the product 3 is advantageously carried out in the following manner.

On effectue le remplissage du container souple 11 en produit 3 via le tuyau 16 (voir la flèche D à la figure 8) et le goulot 14.The flexible container 11 is filled with product 3 via the pipe 16 (see arrow D in FIG. 8) and the neck 14.

Une fois ce remplissage terminé, on procède à une fermeture étanche du container 11 par scellage du goulot 14, par exemple mis en oeuvre au moyen du collier de serrage 18 comme indiqué à la figure 9, puis on dispose un couvercle 20a sur le container 20 en vue du stockage et de l'expédition en clientèle du produit 3, comme illustré à la figure 10. Ce couvercle 20a est avantageusement métallique, à l'instar du container 20.Once this filling is complete, the container 11 is sealed by sealing the neck 14, for example implemented by means of the clamping collar 18 as shown in FIG. 9, then a lid 20a is placed on the container 20 for the storage and shipping of the product 3, as shown in Figure 10. This cover 20 is preferably metallic, like the container 20.

Comme illustré à la figure 11, le client utilisateur du produit 3, après avoir ôté ce couvercle 20a, pratique une découpe 22 en forme de rondelle (représentée en pointillés) sur le container 11, cette découpe 22 ayant pour effet de détacher le goulot 14 scellé du container 11.As illustrated in FIG. 11, the user of the product 3, after having removed this cover 20a, makes a cutout 22 in the form of a washer (shown in dotted lines) on the container 11, this cutout 22 having the effect of detaching the neck 14 sealed container 11.

Ensuite, comme illustré à la figure 12 et à l'instar de la description réalisée ci-dessus en référence à la figure 5, il dispose un appareillage d'enduction comportant un plateau « suiveur » 7 qui est appliqué sur le tronçon annulaire 17 en coulissant à l'intérieur du container 20 et qui se prolonge verticalement en son centre par une conduite d'évacuation 8 communiquant avec le produit 3 du fait de la découpe 22. L'utilisateur procède à l'évacuation du produit 3 en exerçant une pression vers le bas (voir flèches E) sur ce plateau 7, de sorte à entraîner le produit 3 vers le haut (voir flèche

  • F) en direction d'une unité de fabrication, par exemple pour préparer les colles ou joints précités.
Then, as illustrated in FIG. 12 and as in the description made above with reference to FIG. 5, it has a coating apparatus comprising a "follower" plate 7 which is applied to the annular section 17 sliding inside the container 20 and which extends vertically in its center by a discharge pipe 8 communicating with the product 3 due to the cutout 22. The user carries out the evacuation of the product 3 by exerting pressure downwards (see arrows E) on this plate 7, so as to drag the product 3 upward (see arrow
  • F) in the direction of a manufacturing unit, for example to prepare the aforementioned glues or joints.

On notera que le scellage parfaitement étanche du container intérieur souple 11 qu'autorise le goulot 14 qu'il comporte permet d'éviter toute opération de retournement du container 11 en vue d'améliorer l'étanchéité du stockage et de l'expédition du produit 3, tel que ledit catalyseur, à l'intérieur du container rigide 20.It will be noted that the perfectly tight sealing of the flexible inner container 11 authorized by the neck 14 that it contains makes it possible to avoid any operation of turning the container 11 over in order to improve the sealing of the storage and shipping of the product. 3, such as said catalyst, inside the rigid container 20.

Il en résulte notamment les avantages suivants, contrairement aux dispositifs de stockage connus selon les figures 1 à 5 :

  • le container souple 11 n'est pas susceptible de se déchirer par retournement et, par conséquent, aucune cristallisation ni fuite du catalyseur 3 n'est à craindre de ce fait ;
  • l'opération de découpe du container 11 pour le détachement du goulot 14 est aisée et non salissante, du fait que le goulot 14 est formé en saillie au-dessus du tronçon annulaire 17 à la manière d'un épaulement, ce qui permet d'éviter toute perte de catalyseur 3 lors de cette découpe en réduisant ainsi le coût de fabrication des colles ou joints finalement obtenus et en préservant l'environnement ;
  • on minimise le volume d'air emprisonné lors de la fermeture du container 11 du fait du scellage du goulot 14 selon l'invention, ce qui permet de ne pas nuire à la mise en oeuvre ultérieure du catalyseur 3 extrait du container 11 ; et
  • le goulot 14 scellé présente un caractère esthétique amélioré, en comparaison de celui du ruban adhésif 4 de l'art antérieur qui était appliqué sur les bords 1a de l'ouverture du sac 1 à ouverture totale.
This results in particular from the following advantages, unlike the known storage devices according to FIGS. 1 to 5:
  • the flexible container 11 is not susceptible to tearing by inversion and, therefore, no crystallization or leakage of the catalyst 3 is to be feared thereby;
  • the operation of cutting the container 11 for the detachment of the neck 14 is easy and not messy, because the neck 14 is formed projecting above the annular section 17 in the manner of a shoulder, which allows to avoid any loss of catalyst 3 during this cutting thereby reducing the manufacturing cost of adhesives or joints finally obtained and preserving the environment;
  • the volume of air trapped during closure of the container 11 is minimized because of the sealing of the neck 14 according to the invention, which makes it possible not to interfere with the subsequent use of the catalyst 3 extracted from the container 11; and
  • the sealed neck 14 has an improved aesthetic character, compared with that of the adhesive tape 4 of the prior art which was applied to the edges 1a of the opening of the bag 1 to total opening.
