Fluid handling devices

Claim 1

A DEVICE FOR USE WITH A LIQUID CONTAINER HAVING A LIQUID OPENING THEREIN TO SEAL SAID LIQUID OPENING AND TO ENABLE LIQUID TO BE WITHDRAWN FROM THE CONTAINER WHILST SIMULTANEOUSLY PASSING AIR THERETO, WHICH DEVICE COMPRISES A GLAND ADAPTED TO ENGAGE THAT LIQUID OPENING IN FLUID-TIGHT RELATIONSHIP THEREWITH, A TUBULAR BODY RECIPROCABLE IN FLUID-TIGHT RELATIONSHIP THROUGH SAID GLAND, A SEAL CLOSINGL THE OUTER END OF SAID BODY, AN APERTURE SERVING AS AN AIR ENTRANCE AND AS A LIQUID EXIT FORMED IN THE WALL OF SAID BODY NEAR THE OUTER END THEREOF, SAID APERTURE BEING EXPOSED WHEN SAID BODY IS PULLED OUTWARDLY THROUGH SAID GLAND, AND CONCEALED WHEN SAID BODY IS PUSHED INWARDLY THROUGH SAID GLAND, A LIQUID INLET TO SAID BODY ON THE SAME SIDE THEREOF AS SAID APERTURE AND AN AIR OUTLET FROM SAID BODY ON THE OPPOSITE SIDE THEROF FROM SAID APERTURE, SAID LIQUID INLET AND SAID AIR OUTLET BEING POSITIONED TO COMMUNICATE WITH THE INTERIOR OF THE CONTAINER WHEN SAID BODY IS PULLED OUTWARDLY THROUGH SAID GLAND, SAID APERTURE BEING AT AT LEAST LARGE ENOUGH AND SAID AIR OUTLET AT LEAST SMALL ENOUGH TO ENSURE THAT, WHEN THE DEVICE IS USED AT 15* C. WITH A LIQUID HAVING A PENETRABILITY BY AIR FLOWING THROUGH THE AIR OUTLET WHICH IS SUBSTANTIALLY LESS THAN THE PENETRABILITY OF A SURFACE ACTIVE DETERGENT OF VISOCITY 150 CENTISTOKES AT 15*C., A PORTION OF THE APERTURE REMAINS CLEAR OF THE LIQUID BEING DELIVERED, WHCIH PORTION IS SUFFICIENTLY LARGE TO PERMIT AIR TO FLOW SMOOTHLY THROUGH THE APERTURE COUNTER-CURRENTLY WITH THE LIQUID AND THENCE THROUGH THE BODY, COUNTER-CURRENTLY WITH THE LIQUID, AND THE AIR OUTLET AT A RTE SUFFICIENT TO REPLACE THE LIQUID BUT INSUFFICIENTLY LARGE TO PERMIT SUCH FLOW OF AIR WHEN THE DEVICE IS USED AT 15*C. WITH WATER.

Claim 2

A DEVICE FOR USE WITH A LIQUID CONTAINER HAVING A LIQUID OPENING THEREIN TO SEAL SAID LIQUID OPENING AND TO ENABLE LIQUID TO BE WITHDRAWN FROM THE CONTAINER WHILST SIMULTANEOUSLY PASSING AIR THERETO, WHICH DEVICE COMPRISES A GLAND ADAPTED TO ENGAGE THAT LIQUID OPENING IN FLUID-TIGHT RELATIONSHIP THEREWITH, A TUBULAR BODY RECIPROCABLE IN FLUID-TIGHT RELATIONSHIP THROUGH SAID GLAND, A SEAL CLOSINGL THE OUTER END OF SAID BODY, AN APERTURE SERVING AS AN AIR ENTRANCE AND AS A LIQUID EXIT FORMED IN THE WALL OF SAID BODY NEAR THE OUTER END THEREOF, SAID APERTURE BEING EXPOSED WHEN SAID BODY IS PULLED OUTWARDLY THROUGH SAID GLAND, AND CONCEALED WHEN SAID BODY IS PUSHED INWARDLY THROUGH SAID GLAND, A LIQUID INLET TO SAID BODY ON THE SAME SIDE THEREOF AS SAID APERTURE AND AN AIR OUTLET FROM SAID BODY ON THE OPPOSITE SIDE THEROF FROM SAID APERTURE, SAID LIQUID INLET AND SAID AIR OUTLET BEING POSITIONED TO COMMUNICATE WITH THE INTERIOR OF THE CONTAINER WHEN SAID BODY IS PULLED OUTWARDLY THROUGH SAID GLAND, SAID APERTURE BEING AT AT LEAST LARGE ENOUGH AND SAID AIR OUTLET AT LEAST SMALL ENOUGH TO ENSURE THAT, WHEN THE DEVICE IS USED AT 15* C. WITH A LIQUID HAVING A PENETRABILITY BY AIR FLOWING THROUGH THE AIR OUTLET WHICH IS SUBSTANTIALLY LESS THAN THE PENETRABILITY OF A SURFACE ACTIVE DETERGENT OF VISOCITY 150 CENTISTOKES AT 15*C., A PORTION OF THE APERTURE REMAINS CLEAR OF THE LIQUID BEING DELIVERED, WHCIH PORTION IS SUFFICIENTLY LARGE TO PERMIT AIR TO FLOW SMOOTHLY THROUGH THE APERTURE COUNTER-CURRENTLY WITH THE LIQUID AND THENCE THROUGH THE BODY, COUNTER-CURRENTLY WITH THE LIQUID, AND THE AIR OUTLET AT A RTE SUFFICIENT TO REPLACE THE LIQUID BUT INSUFFICIENTLY LARGE TO PERMIT SUCH FLOW OF AIR WHEN THE DEVICE IS USED AT 15*C. WITH WATER.
