Title
(EN) DRIP RESISTANT DISPENSING VALVE FOR FLUIDS
(FR) robinet de distribution antigoutte pour des fluides
Abstract
(EN)
A drip resistant dispensing valve for fluids is disclosed, which provides a dispensing outlet configured to minimize the tendency for fluid to drip from the valve following a dispensing operation. The dispensing outlet exhibits curved interior surfaces and a curved outlet face construction; the face situated a distance away from the valve body. Such construction assists in minimizing the retention of fluid on the surfaces of the dispensing outlet, and migration of the fluid to surfaces outside of the dispensing outlet that could tend to promote growth of biological contaminates and/or provide additional surfaces that could pool fluid following a dispensing operation and thereafter drip from the valve. A shell is provided around the dispensing outlet to assist in avoiding contamination of the valve and of the fluid being dispensed through the valve, and to aid in positioning a receptacle for receiving fluid from the dispensing valve.
(FR)
La présente invention concerne un robinet de distribution antigoutte pour des fluides, qui propose un orifice de distribution configuré pour réduire la tendance d'un fluide à goutter à partir du robinet à la suite d'une opération de distribution. L'orifice de distribution présente des surfaces intérieures courbées et une construction à face de sortie courbée ; la face étant située à une certaine distance du corps du robinet. Une telle construction permet de réduire la rétention de fluide sur les surfaces de l'orifice de distribution, et la migration du fluide vers les surfaces en dehors dudit orifice qui pourraient avoir tendance à favoriser la croissance de contaminants biologiques et/ou former des surfaces supplémentaires pouvant accumuler le fluide après une opération de distribution et après cela, goutter du robinet. Une enveloppe est prévue autour dudit orifice afin d'éviter la contamination du robinet et du fluide distribué par le robinet, et de permettre de positionner un réceptacle pour recevoir le fluide à partir dudit robinet.
