AI Technical Summary

Problems solved by technology

The discharge opening is thus located farther from the feed point, which sometimes leads to less than satisfactory manufacturing precision of the discharge opening and of the fluid-guiding surfaces upstream of the flow of the discharge opening
This is disadvantageous, since the discharge behavior of the liquid from dispenser to dispenser may thereby change and no longer correspond to the intended discharge behavior

Abstract

The invention relates to a discharge head (10) for the nasal application of pharmaceutical liquid from a pressure reservoir (110), which has an outlet valve (112), which has a valve connecting piece (114), to which force can be applied against a spring force in order to open the outlet valve (112). Said discharge head has a nasal applicator (12), which extends outward from an actuation surface (32) and at the end of which a discharge opening (98) is provided, which, through an applicator channel (92) of the nasal applicator (12), is connected in a fluid-communicating manner to a hollow tube (42) for connection to the pressure reservoir. According to the invention, the nasal applicator (12) has an inner component (50), which is integrally connected to the actuation surface (32), and an outer component (60), which is designed as a component that is separate from the inner component (50) and which is attached to the inner component in such a way that the outer component surrounds the inner component (50). The discharge opening (98) is provided as a through-hole in the outer component (60), and the outer component (60) and the inner component (50) jointly delimit the applicator channel(92).

Description

technical field [0001] The invention relates to a discharge head for administering a medical solution from a pressure reservoir to the nose, which discharge head has an outlet valve with a valve socket which can be loaded with force against a spring force in order to open the outlet valve. The invention also relates to a dispenser with such a discharge head. Background technique [0002] Similar discharge heads and distributors are known, for example, from DE 10 2012 200 545 A1. The discharge head disclosed in this document has an outer housing which on the one hand contains the base for connection to the pressure reservoir and on the other hand forms the housing of the nasal applicator with the outlet opening. The inner member is inserted into the elongated nasal applicator, and the inner member and the housing are used together to direct the liquid fluid to the discharge opening. [0003] A similar construction is also known from US Design Patent Publication No. US D 659...
