Abstract:
A container holding a pressurizing fluid comprises a resilient member to be positioned in the container wall and formed with a valve opening. A plug is positioned in the opening to normally close it, but the resilient member will flex to permit the release of fluid through the valve opening past the plug in response to a predetermined difference between the pressure inside and that outside the container. The container is enclosed within an outer jacket holding a fluid to be dispensed, which is maintained under a constant pressure equal to the pressure of said pressurizing fluid less the pressure required to flex said resilient member.
Abstract:
The present invention concerns a hair curler comprising a retaining bar articulated on to one end of the curler body, the articulation consisting of a ring that revolves freely around the end of the curler body and hinge connecting said ring with the retaining bar, the axis of the hinge being perpendicular to the axis of the curler.
Abstract:
Valve for dispensing a variable number of pressurized fluids comprises a central tube with a lateral orifice for each fluid to be dispensed, and a separate sleeve for each orifice in which said tube is slidable to move said orifices from positions in which they are closed by said sleeves to open positions.
Abstract:
Curling iron comprises heating member and a flexible sleeve loosely fitted into said member, said sleeve being provided with external, radially projecting conical pins.
Abstract:
Spout for dispensing fluids from pressurized containers comprises baffle disc which slows ejection of fluid and rim which, when applied to surface to be sprayed, limits the area of application.
Abstract:
CONTAINER HAS CONCAVE BOTTOM, AND CARTRIDGE OF PRESSURIZING GAS WITHIN IT NEAR THE BOTTOM. A RESILIENT SAFETY DEVICE IS SEATED IN THE BOTTOM AND DEFINES A CENTRAL HOLE. A PIN IS SLIDABLY POSITIONED IN SAID HOLE IN ALIGNMENT WITH THE CARTRIDGE SO AS TO REPTURE SAID CARTRIDGE WHEN DEPRESSED. THE SAFETY DEVICE BLUGES OUTWARDLY WHEN THERE IS EXCESSIVE PRESSURE INSIDE THE CONTAINER, THUS ENLARGING THE HOLE SO THAT GAS CAN ESCAPE AROUND THE PIN.
Abstract:
Hollow hair roller molded from thermoplastic material, comprises a central ring and two end rings connected to the central ring by peripherally spaced strips, with the diameter of the roller increasing from said central ring toward each end ring.
Abstract:
Valve in outer jacket carries depending cup having bottom with annular projection and lateral projection on its side walls. This cup is ultrasonically welded to a connecting member having an annular seat into which the neck of the inner container is screwed and cemented.
Abstract:
A safety device for a container under pressure comprises a resilient member to be positioned in the container wall and formed with a valve opening. A plug is positioned in the opening to normally close it, but the resilient member will flex to permit the release of fluid through the valve opening past the plug in response to excess pressure.
Abstract:
Device for storing two products separately and dispensing them simultaneously comprises a necked container, a covered flanged cup sealed in the neck with its flange lying on the rim of the neck, a trocar above the cup in alignment therewith, removable tear-strip for holding the trocar away from the cup, and means for guiding the trocar to pierce the cup when the tear-strip is removed.
