Problems solved by technology

[0005] However, it is disadvantageous here that a residual quantity of the medium to be dispensed still remains in the area of ​​the outlet opening
Furthermore, the reliable shutdown of the output port poses problems
Furthermore, it is disadvantageous that a section of the channel is released by the movement of the closing element in the channel (retraction of the closing element), so there is a great risk that bacteria can penetrate the channel

Embodiment Construction

[0032] FIG. 1 shows an output head 1 , which is preferably constructed in one piece. The dispensing head has a housing 2 which is mounted or integrally connected to the container and to a dispensing valve (not shown in greater detail) for dispensing a medium, for example a viscous self-foaming and / or gel-like product. The dispensing valve is assigned to the inner container space filled with the medium and can be actuated by means of an opening mechanism by pressing the actuating surface 8 of the dispensing head.

[0033] The outlet head has an outlet opening 3 which is in flow connection via a first channel section 4 and a second channel section 5 . The second channel section is equipped with a closing element designed as a closing piston 6 , which closes the outlet opening 3 .

[0034] Close piston 6 ( image 3 ) has a solid cylindrical handle 6b, at one end of which is molded in the form of a conical barb 6a made of soft flexible material. On the side opposite the barb 6a...

Abstract

The invention relates to a self-closing dispensing head (1) for a pressurised container having a dispensing valve for dispensing substances, in particular viscous, self-foaming and / or gel-type products. The dispensing head (1) comprises an outlet (3) which can be closed by a closing element (6).

Description

technical field [0001] The invention relates to a self-closing dispensing head 1 for pressure vessels with a dispensing valve for dispensing media, in particular viscous, self-foaming and / or gel-like products, wherein the dispensing head has an adjustable Through the outlet opening 3 closed by the closing element, the opening mechanism and the passage for the medium leading to the outlet opening 3, the dispensing valve of the pressure container can be opened in the assembled state by means of the opening mechanism, wherein the passage has a first passage section 4 and The second channel section 5 , and wherein by pressing the operating element 8 both operates the opening mechanism and moves the closing element and the second channel section 5 relative to each other to release the outlet. Background technique [0002] Pressure vessels with outlet heads of conventional design for eg shaving foams and gels generally have non-closable outlet openings. Consequently, it often hap...
