Problems solved by technology

Such a step pollutes the surrounding air, which is very disadvantageous, especially if the nursing staff repeats this preparation (perhaps many times a day) and is therefore often in the position of unnecessarily inhaling one or more active drugs

Embodiment Construction

[0041]Various embodiments of the present invention are described below with reference to the accompanying drawings.

[0042] Figures 1a-1d The spray device in and 2 comprises a housing 1 made of plastics such as polypropylene and having a hollow space 3 for receiving and storing a spray bottle 2 and an outlet 5 in the form of a nozzle through which a dose of (preferably) liquid passes. The nozzle sprays out. Figure 1a-1c depicts the housing 1 prior to installation of an aerosol bottle 2, in this case in the form of a liquid container 4 with a pump 6, Figure 1d The spray unit is shown ready to use.

[0043] In the preferred embodiment in Figure 2, the housing is a generally tubular circular section which is slightly tapered, wherein the centerline of the cone coincides with the centerline of the nozzle. The housing thus has a broad bottom and a narrower top (at the outlet). The housing comprises, from the top down, the integral nozzle 5, housing 1 and linkage arms 8a, 8b....

Abstract

The invention relates to a spray device which comprises a casing (1 ) and a spray bottle (2) and which has in its nozzle (5) a closing element which at the same time substantially fills the nozzle in order to minimise residual amounts of, preferably, a drug 5 in the nozzle, the overall purpose being to protect the spray device from contamination and evaporation. The invention further relates to a method for manufacturing with as few parts as possible a spray device which by usually manual action causes the spray bottle (2) to effect a pumping movement which triggers a spray dose through the nozzle (5). The device is intended to increase dose accuracy and facilitate the actual pumping.

Description

technical field [0001] The invention relates to a spray device with a nozzle closure, primarily for spraying medicaments from liquid containers. The invention also relates to a method of spraying by means of a spray device and a method for the manufacture of such a spray device. Background technique [0002] Known spray devices for everyday use generally comprise a liquid container which is grasped with thumbs located under the bottom of the liquid container and fingers located on each side of the nozzle attached to the liquid container. The spray device can be made to discharge a certain amount of liquid by pressing the bottom of the liquid container with the thumb, applying an opposing clamping force to the pump actuator located at the nozzle end of the liquid container, thereby applying pressure in the axial direction of the liquid container, For example, delivering a specific dose of a drug nasally. Such spray devices are difficult to control because axial movement may...
