Abstract: A method for preparing an infusion beverage is disclosed wherein a dried infusion substance is applied in an infusion container, the latter being present, in the first instance, in a collapsed state and being extendable into an expanded state, An infusion liquid is introduced into the infusion container, wherein the infusion container is expanded. The dried infusion substance in the infusion container is kept in contact with the infusion liquid, in order to form the infusion beverage, over a contact period. The infusion container is then returned to its collapsed state, at least in part, by compression and, in the process, at least some of the infusion beverage is expelled from the infusion container.

Abstract: An active electro-optical filtering device, such as a glare-protection device is disclosed. The device is equipped with a light-protection filter having at least one active optical filter element, an electronic device for controlling the active filter element, a light sensor working together with the electronic device, and an electrical current supply for the electronic device and the at least one active filter element. In order to improve the efficiency in production and employment, the light-protection filter is arranged in a filter component and the electronic device, the light sensor and the electric current supply are arranged in a physically separate control component, wherein the filter components can be releasably connected mechanically and electrically to form a total unit, and for this purpose, are equipped with mutually cooperating mechanical and electrical connecting elements.

Abstract: The method described relates to conditional dosing and nebulisation of a liquid or powdered preparation for inhalation. The condition for dosing and nebulisation of the preparation is that the inhaling person must produce an inhalation power according to his or her constitution and which is sufficient for an optimum effect of the inhaled preparation. Without this minimum inhalation power, no dosing and no nebulisation of the preparation is possible. The corresponding inhalation device comprises a known device for dosing and nebulising (without condition) and additional means which inhibit actuation of the device by positive locking until the minimum inhalation power is produced by the inhaling person. A preferred embodiment has, for dosing and nebulisation, a reservoir with a dosing and nebulising pump and, for said positive locking, a ball (13), which is loosely housed in a corresponding ball chamber (14).

Abstract: A process is described for producing a valve-and-lid assembly composed of a lid and a valve body each of which has a determined configuration and is produced separately in finished condition, the valve body from a synthetic resin of physical properties similar to those of Hytrel, with a Shore hardness of about 78 to 92 when the valve body is to be assembled with an upper body portion resting on the outer lid face about a collar of the lid; and of about 70 to 92 when the valve body is to be introduced completely into the lid collar. The valve body is then placed partially into the collar, or on the mandrel of a pressure piston, and then abruptly struck by the piston to be rammed fully into the collar and stretched so that a lower head of the valve body is moved downwardly just out of a central lid opening at an internal collar end. The mandrel is then withdrawn, permitting the valve body to contract whereby its head sealingly engages the rim about the central opening of the collar.

Abstract: A valve-and-lid assembly comprises a self-closing discharge valve constituted by a dome part, having a central opening, of a lid closing the open top end of a pressurized container and serving as the obturating member of the valve by obturating ducts through a valve disc of elastically resilient material which is lodged in the dome part. When opening the valve by downward or tilting pressure exerted with the aid of a tubulure or the like actuating member on the valve disc, the latter is deformed so as to establish free communication between at least one of the ducts therein and the hollow interior of the tubulure which can carry a conventional atomizer head having a spray nozzle.

Abstract: A valve-and-lid assembly adapted for closing off the open top end of a pressurized container comprises a lid having a dome part protruding on an upper or lower face of the lid and having a central opening. A valve disc of elastically resilient material is lodged in the dome part and extends with a valve head part thereof through the central opening. The latter is surrounded by an axially extending collar portion of the dome part depending from a flat top wall of the latter and having an annular rim about the opening which is in sealing contact with a contact face of the valve head when the valve is closed, thereby obturating product ducts provided in the valve disc.
