Embodiment Construction

[0025] figure 1 A cross-section through a spray head according to the invention is shown, which has a spray head body 10 , a holding element 12 and a conduit element 14 . The spray head body 10 comprises a fastening ring 16 with inwardly protruding protrusions 18, by means of which the fastening ring 16 can be connected to a spray container (not shown). The sprinkler head body 10 also includes an actuation element 20 having an actuation recess 22 .

[0026] The holding element 12 has an inlet 24 , an adjoining conduit section 26 and a subsequent holding section 28 . The holding section 28 is bent through 90° and is additionally supported by the wall 30 . The holding element 12 also has an appendix 32 with a rear wall 34 (cf. Figure 2-5 ). The appendage 32 is open on its side facing the actuation recess 22 .

[0027] A catheter element 14 in the form of a capillary is inserted into the holding element 12 . The capillary is used to atomize the mixture of medium and propel...

Abstract

The invention relates to a spray head for atomising a medium using a pressurised propellant, with a spray head body (10) which comprises a fastening ring (6) and an actuating element (20) movably connected thereto, a holding element (12) which comprises an inlet port (24), an adjoining duct section (26) and a holding section (28), and a duct element (14) which has an outlet port (62) for the medium and which has in at least one section a diameter such that the medium to be discharged atomizes in the flow of propellant, the duct element (14) preferably being a capillary pipe or capillary tube and / or having a constant diameter over its entire length, the duct element (14) being arranged in the holding section (28) of the holding element (12) and, preferably, being bent through approximately 90° in the holding section (28) of the holding element (12) and the holding element (12) preferably being connected to the spray head body (10). The assembly of this spray head is made easier by the fact that the holding element (12) comprises, at least in the holding section (28), particularly at the upper end thereof, at least one clamping element (50) for clamping or latching the duct element (14) on the holding element (12).

Description

technical field [0001] The invention relates to spray heads for atomizing media. These spray heads are mounted on spray cans or bottles and are actuated by simple pressure on the operating mechanism so that the medium is delivered in a spray pattern. Background technique [0002] Traditional aerosol spray systems work with large volumes of propellant gas as the medium is sprayed through complex valve and nozzle structures. [0003] A valve is known from WO 03 / 051522 A1 in which the medium is atomized or sprayed through capillaries rather than through nozzles. This known valve is designed for flow rates of 0.5 g / s to 0.01 g / s. WO03 / 051522A1 describes how to choose the size of the capillary of the valve to allow spraying of the atomized medium. As a result of the use of capillary tubes, a volume ratio of medium to propellant gas of only 1:50 to 1:5000 is required at atmospheric pressure. At the same time, little propellant gas is required and the spray container can be des...
