Abstract

The servo system reduces the effort needed when actuating an aerosol can spray head. It has a taper pin with cylindrical end portions actuating the head, the pin and the cylinder in which it works being of injection-moulded plastics with a low coefficient of friction. When the pin is pressed right in, continuous spraying is possible without finger pressure. A thin layer of plastics is sprayed onto the smaller pin bore of the taper, making it impossible for sample spraying to be carried out without being noticed. The ends of the pin work in a cylinder, from which the larger end of the taper portion protrudes radially, this being pressed in the radial direction to actuate the spray head.

Description

Bett,: Antrag auf Erteilung eines Patentes für ein EI Servosystem für die Sprühkopfbetätigung an Spraydosen" Bisher werden sämtliche Sprühköpfe durch direkten Fingerdruck betätigt, dabei treten Jetätigungskräfte bis zu 4 kp auf. Beim Dauersprühen muß diese Kraft bis zum 1eersprühen der Dose aufgebracht werden. Diese Kraft führt zu einer Überbelastung des fingers, so daß nicht durchgehend gesprüht werden kann, was zu einer ungleichmäßigen Sprühmittelabgabe führt.Bed: Application for a patent for an EI servo system for spray head actuation on spray cans "So far, all spray heads have been through actuated by direct finger pressure, with jet actuation forces of up to 4 kp. At the Continuous spraying, this force must be applied until the can is empty. These Force leads to an overload of the finger, so that not sprayed continuously resulting in uneven spray delivery.

Durch meine Erfindung wird der Spriihkopf durch einen konischen Stift betätigt, der die Betätigungskraft auf 10% reduziert.With my invention, the spray head is made by a conical pin operated, which reduces the operating force to 10%.

Die Endteile des konischen Stiftes sind zylindrisch und werden in einem Zylinder geführt, der durch Preßsitz auf dem Oberteil der Spraydose gehalten wird. Der größere Durchmesser des konischen Stiftes ragt radial aus dem Zylinder hervor, dadurch kann die Betätigung der Spraydose mühelos durchgeführt werden Bei radialer Betätigung drückt der Konus den Sprühkopf nach unten, Auf Grund der Reibungsverhältnisse bewirkt ein Loslassen des Konus ein Stoppen des Sprühvorganges, ebenso kann jede Sprühsterke eingestellt werden. Beim vollständigen leersprühen wird der Stift vollständig eingedrückt und kann Losgelassen werden. Dabei ist die Druckrichtung und Sprührichtung identisch, lurch Vorspritzen einer dünnen Kunststoffschicht an der kleineren Stiftbohrung des Konus ist ein unerwünschtes und unkonntrolliertes irobespritzen wirkungsvoll verhindert.The end portions of the conical pin are cylindrical and are in guided by a cylinder which is held by an interference fit on the upper part of the spray can will. The larger diameter of the conical pin protrudes radially out of the cylinder so that the operation of the spray can can be carried out effortlessly radial actuation, the cone pushes the spray head downwards, due to the friction conditions If you let go of the cone, the spraying process will stop, as can any Sprühsterke can be adjusted. When completely emptying the pen becomes complete pressed in and can be released. Here is the direction of pressure and direction of spray identical, by pre-molding a thin layer of plastic on the smaller pin hole of the cone, unwanted and uncontrolled irobespritzen is effective prevented.
