Abstract: A manometer device for continuous monitoring of the air pressure in vehicle tires is described which consists of a manometric capsule and an electrical indicator device associated therewith. A flatly conical membrane with a cylindrical projection is arranged transversely through the interior space of the manometric capsule. A permanent magnet is inserted in this projection. The membrane divides the interior space of the manometric capsule into two chambers, of which one chamber is stressed with a nominal pressure and the other chamber is connected to the pressure space of a vehicle tire. A stationary sensor, which is associated with the manometric capsule to be mounted on a rim flange, responds to linear magnetic field variations and transmits the latter to a terminal.

Abstract: A sealing cap for a container provided with a safety valve is described, this sealing cap consisting of a bottom part which can be screwed onto the container neck and firmly locked there and of a top part which can be screwed onto the bottom part. The bottom part serves to seal absolutely the container neck provided with the safety valve, by compressing, in a moisture-tight manner, the joint between the edge of the container neck and a molding forming the valve support. The bottom part, fixed in position by retaining tabs and detent lugs, and capable of being loosened only by force, remains fixedly connected to the container during use. The top part can be unscrewed.

Abstract: A flat, rectangular box 4 formed of cardboard contains a bag 18 of multi-layered foil material. A tube 24, which is disposed in the interior of the box in the transport condition of the package and can be removed from the box interior through an opening 10 which is closed by a tear-off strip, which is connected in liquid-tight manner to the bag 18 by a connecting piece. An outlet 36 provided at the free end of the tube is controlled by a pressure relief valve, which is provided in the tube and opens in the direction of the outlet. The walls of the narrow sides of the box each have a longitudinal fold along which these walls can fold outwards when the broad sides of the box are pressed together in order to empty the bag filled with a fluid, e.g. coffee extract. The one-way package is particularly suitable for use in a beverage vending machine in place of the storage containers employed until now.
