    Abstract: A VERTICALLY COLLAPSIBLE PRODUCT-ISOLATING SACK HAVING A REDUCED NECK PORTION AT ITS TOP, THROUGH WHICH THE PRODUCE PASSES, AND HAVING BELOW SAID NECK PORTION AN EXTERNALLY GROOVED ANNULAR SHOULDER ADAPTED TO FIT WITHIN THE TOP SHOULDER OF THE DISPENSER CASING AND TO PROVIDE PASSAGES WITHIN THE CASING SHOULDER FOR THE CHARGING OF THE CASING WITH PROPELLANT LIQUID. DURING SAID CHARGING THE ACK NECK IS SUPPORTED ABOVE THE CASING NECK AND IS SPACED RELATION THERETO, AND THE PROPELLANT LIQUID PASSES THROUGH THE EXISTING SPACE BETWEEN THE NECKS AND THROUGH THE GROOVES OF THE SACK SHOULDER, BEING BROUGHT INTO THE CASING.

    Abstract: A dispenser comprising a can containing pressurized liquid and having a valve to control the discharge. Connected with the valve and disposed inside the can is a second valve and a collapsible container, the latter having flexible walls and a watery product therein such as hydrogen peroxide which is pressurized due to the pressure existing against the flexible container walls. The second valve controls the outflow of the watery product from the container as effected by the pressure against the walls thereof. In this environment the invention provides, within the said container and connected to the second valve, a capillary tube constituting a discharge passage. The capillary tube may constitute a dip tube, and has the effect of smoothing out the rate of discharge of the watery product from the container under conditions of different pressures.

    Abstract: A tilting-type aerosol valve comprising a cup-shaped valve housing which is covered by a resilient annular discharge-valve seat. A hollow valve stem extends through the valve seat and carries an annular valve shoulder inside the housing. The shoulder is engageable with the seat to close off the discharge. Within the housing there is a supporting boss on the valve stem, located below the valve shoulder and engageable with an opposite wall of the valve housing to normally maintain the valve shoulder and seat engaged whereby the valve is closed. The stem can be tilted, however, because the shoulder can compress a localized area of the seat. This separates another portion of the shoulder from the seat, whereby liquid can flow from the housing, but through the hollow valve stem.
