Description

A élioration à un dispositif délivrant des mousses, en particulier une mousse de polyuréthanneImprovement to a device delivering foams, in particular polyurethane foam
La présente invention concerne une amélioration à un dispositif pour délivrer un ou plusieurs composants moussants à partir d'un container. Il s'agira généralement d'une mousse de polyuréthanne à un ou deux composants devant être appliquée à partir d'une bombe de type aérosol.The present invention relates to an improvement to a device for delivering one or more foaming components from a container. It will generally be a polyurethane foam with one or two components to be applied from an aerosol can.
On sait que pareil composant moussant peut être éjecté du récipient par manipulation d'une valve libérant une ouverture vers un adaptateur fixé sur ladite valve, l'adaptateur étant en communication avec un tuyau distributeur, en général flexible, qui permet l'application de la mousse à un endroit précis.It is known that such a foaming component can be ejected from the container by manipulation of a valve releasing an opening towards an adapter fixed on said valve, the adapter being in communication with a dispensing hose, generally flexible, which allows the application of the foam in a specific place.
Ces adaptateurs en plastique peuvent prendre diverses formes, en particulier selon le type de valve associé, et sont utilisés depuis plus de 25 années pour délivrer le contenu d'une bombe de type aérosol. Différents moyens de fixation sur la valve ont été proposés. En général cependant l'adaptateur est vissé sur un pas de vis extérieur de la valve. En inclinant ou en poussant sur l'adaptateur, la valve s'ouvre et le (s) liquide (s) moussant (s) sortent via l'adaptateur pour parvenir à l'extrémité du tube distributeur y fixé. La fixation du tube est en général réversible et est effectuée généralement par friction sur l'extérieur ou l'intérieur d'un embout, éventuellement à pas de vis, dentelé ou cranté, prévu par exemple de moulage sur l'adaptateur. Le tube sera généralement flexible et composé d'une matière plastique. Une autre méthode pour appliquer des liquides moussants contenus dans des récipients aérosols consiste a utiliser un applicateur (pistolet à mousse) . Dans ce cas il n 'y a pas d'adaptateur et de tube. En activant la gâchette de 1 ' applicateur, le liquide moussant est éjecté à l'extrémité du canon du pistolet.These plastic adapters can take various forms, in particular depending on the type of associated valve, and have been used for more than 25 years to deliver the contents of an aerosol can. Different means of attachment to the valve have been proposed. In general, however, the adapter is screwed onto a thread outside the valve. By tilting or pushing on the adapter, the valve opens and the foaming liquid (s) exit via the adapter to reach the end of the attached dispensing tube. The fixing of the tube is generally reversible and is generally carried out by friction on the outside or inside of a nozzle, possibly with a thread, serrated or notched, provided for example by molding on the adapter. The tube will generally be flexible and made of plastic. Another method for applying foaming liquids contained in aerosol containers is to use an applicator (foam gun). In this case there is no adapter and tube. By activating the trigger of the applicator, the foaming liquid is ejected at the end of the gun barrel.
On a constaté, lors d'expériences comparatives, que le dispositif adaptateur/tube fournit des mousses de densité supérieure à celles obtenues en utilisant un pistolet.It has been found, in comparative experiments, that the adapter / tube device provides foams of higher density than those obtained using a gun.
Les utilisateurs professionnels de mousse 1KPU ou 2KPU (1 ou 2 composants) contenus dans des bouteilles ou bombes aérosols utilisent en général des pistolets et obtiennent donc des mousses de densité inférieure. Les propriétés physiques sont différentes et en général de qualité inférieure à celles de mousses de densité plus importante.Professional users of 1KPU or 2KPU foam (1 or 2 components) contained in bottles or aerosol cans generally use guns and therefore obtain lower density foams. The physical properties are different and generally of lower quality than those of higher density foams.
Les consommateurs finaux utilisent en général des mousses 1KPU en utilisant un adaptateur et un tube et obtient donc en général des mousses de densité supérieure.End consumers generally use 1KPU foams using an adapter and tube and therefore generally obtain higher density foams.
L'invention propose de surmonter les désavantages associés a cette différence de densité de façon à ce que l'utilisateur puisse choisir entre une mousse de haute densité et une mousse de plus basse densité. Les mousses de haute densité sont utilisées par exemple pour la fixation de châssis de fenêtres. Les mousses de basse densité servent de matière de remplissage ou d'obturation: le but est d'obtenir le maximum de mousse à partir d'un récipient, c'est à dire à partir d'un volume donné. On dira dans ce dernier cas que le "rendement" est supérieur. L' invention se propose d'obtenir de manière simple un rendement supérieur avec un dispositif adaptateur/tube. L'invention consiste à prévoir un rétrécissement dans le canal du tube amenant le flux de matière moussante. On considère alors qu'il y a une augmentation de la vitesse au point de rétrécissement et une diminution correspondante de la pression à la sortie du rétrécissement. L'effet venturi ainsi obtenu augmente la "capacité de moussage" du liquide délivré.The invention proposes to overcome the disadvantages associated with this difference in density so that the user can choose between a high density foam and a lower density foam. High density foams are used for example for fixing window frames. Low density foams serve as filling or filling material: the aim is to obtain the maximum amount of foam from a container, that is to say from a given volume. In the latter case, we will say that the "yield" is higher. The invention proposes to obtain simply a higher yield with an adapter / tube device. The invention consists in providing a narrowing in the channel of the tube bringing the flow of foaming material. It is then considered that there is an increase in the speed at the narrowing point and a corresponding decrease in the pressure at the outlet of the narrowing. The venturi effect thus obtained increases the "foaming capacity" of the liquid delivered.
On peut donc, selon l'invention, créer un ou plusieurs effets venturi à l'intérieur de l'adaptateur en plastique, ou le long du tube cylindrique ou de section ovale ou encore en prévoyant un embout, par exemple sous la forme d'un anneau ou section tubulaire de rétrécissement, à l'adaptateur, le long ou à l'extrémité du tube.It is therefore possible, according to the invention, to create one or more venturi effects inside the plastic adapter, or along the cylindrical tube or of oval section or even by providing a nozzle, for example in the form of a tubular narrowing ring or section, at the adapter, along or at the end of the tube.
L'adaptateur à "haut rendement", avec ou sans embout ou tube, selon l'invention, peut être vissé sur le pas de vis mâle de la valve, de manière classique. Le diamètre interne est en général d'au moins 1 mm de façon à assurer une production minimum aux différentes températures du récipient. En général pour les mousses de PU, l'adaptateur et le tube ont un diamètre interne d'environThe "high efficiency" adapter, with or without end piece or tube, according to the invention, can be screwed onto the male screw thread of the valve, in a conventional manner. The internal diameter is generally at least 1 mm so as to ensure minimum production at the different temperatures of the container. In general for PU foam, the adapter and the tube have an internal diameter of about
6 mm.6 mm.
Le rétrécissement peut également se trouver à différents endroits du canal du tube conduisant la mousse, par exemple sous la forme d'une bague. Avantageusement l'effet venturi est simplement obtenu à l'extrémité du tube par un embout ayant une ouverture variant de 1 à 5 mm. Le diamètre de cet embout déterminera la densité de la mousse résultante. Selon une autre variante, l'embout comprend plusieurs ouvertures plus petites.The narrowing can also be found at different places in the channel of the tube leading to the foam, for example in the form of a ring. Advantageously, the venturi effect is simply obtained at the end of the tube by a nozzle having an opening varying from 1 to 5 mm. The diameter of this tip will determine the density of the resulting foam. According to another variant, the end piece comprises several smaller openings.
L'embout peut être fixé par friction, collé ou vissé.The end piece can be fixed by friction, glued or screwed.
On a constaté qu'en utilisant un "dispositif à haut rendement" selon l'invention on obtient un rendement amélioré de 30 % par rapport au dispositif classique adaptateur/tube .It has been found that by using a "high-efficiency device" according to the invention, an efficiency improved by 30% is obtained compared to the conventional adapter / tube device.
Selon l'autre variante susmentionnée, l'adaptateur est constitué d'un anneau présentant un disque percé d'un certain nombre de trous, de préférence circulaires, et placé transversalement dans le canal du tube. Au lieu d'un trou central, il y a donc de 2 à plus de 20 trous de plus petit diamètre, variant par exemple de 0,1 mm à 20 mm, de préférence de 0,3 mm à 1,8 mm, plus préférentiellement de 0,5 mm à 1,5 mm. Le fait de prévoir plusieurs trous s'est avéré avantageux en ce qui concerne le rendement qui peut ainsi augmenter de 30%.According to the other variant mentioned above, the adapter consists of a ring having a disc pierced with a number of holes, preferably circular, and placed transversely in the channel of the tube. Instead of a central hole, there are therefore from 2 to more than 20 holes of smaller diameter, varying for example from 0.1 mm to 20 mm, preferably from 0.3 mm to 1.8 mm, more preferably from 0.5 mm to 1.5 mm. Providing several holes has proven to be advantageous with regard to the yield, which can thus increase by 30%.
On a aussi constatéWe also found
- une expulsion plus régulière et plus facilement contrôlable du boudin de mousse,- a more regular and more easily controllable expulsion of the foam rod,
- une expansion retardée de la mousse moins importante durant le durcissement,- less delayed foam expansion during hardening,
- un durcissement plus rapide de la mousse même à une température du container de + 5°C et une température ambiante de - 10°C, - un écoulement latéral (sagging) moindre de la mousse fraîchement expulsée.- faster curing of the foam even at a container temperature of + 5 ° C and an ambient temperature of - 10 ° C, - less lateral flow (sagging) of the freshly expelled foam.
