Abstract

Selon cette invention, un distributeur comporte un corps (1) cylindrique, creux, allongé, ouvert au niveau de l'une (2) de ses extrémités et fermé au niveau de l'autre extrémité (3) par un orifice d'évacuation (4) recouvert d'une membrane friable. Une quantité de préparation fluide occupe un espace (7) ménagé à l'intérieur du corps (1), entre l'orifice (4) et une masse (8) circulaire d'un matériau épais, pouvant subir une extrusion et inerte vis-à-vis de ladite préparation fluide. La masse (8) est positionnée sur un piston (9) doté d'un propulseur (13) venant au contact de l'autre côté du piston. Un ressort de compression (15) est positionné entre ce propulseur (13) et une fermeture (11) située au niveau de l'extrémité (2) du corps (1). La force de ce ressort (15) peut être libérée grâce au retrait d'un écrou à oreilles (non indiqué) de l'extrémité d'une tige (16) filetée s'étendant librement dans un trou lisse (18) ménagé dans la fermeture (11) et vissée au niveau de son autre extrémité dans un trou (17) fileté ménagé dans le propulseur (13). Un dispositif d'évacuation destiné à diffuser une préparation fluide, dans un matériau tel que du bois ou dans un ouvrage de maçonnerie, peut être fixé en couplage serré à l'orifice d'évacuation (4). Ce dispositif comporte un organe tubulaire souple (21) inséré et scellé à l'intérieur d'un trou (40) ménagé dans un matériau (41) tel que du bois ou dans un ouvrage de maçonnerie. Un adaptateur té (22) couple l'orifice d'évacuation avec l'organe (21) et les bras de l'adaptateur (22) permettent d'insérer un tournevis dans l'organe (21) de manière à sceller l'organe (21) dans le trou (40). Après retrait du tournevis, un bouchon de fermeture (25) est appliqué pour empêcher les fuites de la préparation fluide. Un couvercle protecteur (44) peut également être utilisé.
