Embodiment Construction

[0018] figure 1 A cross-sectional view showing the four stages of the self-closing valve 01 according to the invention in the transition from the closed position to the delivery position. figure 1 Inset a) of a) shows the valve 01 in the closed position. figure 1 Insets b) and c) show the transition to the delivery position, while figure 1 Inset d) of shows valve 01 in delivery position. Generally speaking for the understanding of the figures, the valve is designed to fit on a container (not shown), for example by fitting into the neck of a squeeze bottle.

[0019] The valve 01 comprises an annular valve membrane 02 which has an annular central delivery opening 03 . The valve membrane 02 is substantially in the form of a disk spring and also exhibits a relative spring characteristic. exist figure 1 Inset a) of , the valve membrane 02 shows a position when the valve 01 is closed. In the closed position, the valve membrane 02 rests with its delivery opening 03 on the stop ...

Abstract

The invention relates to a self-closing valve (01) for dispensing a free-flowing product. The valve has a valve membrane (02) with an opening for dispensing (03) and an encircling edge (11) at the outer perimeter, wherein the valve membrane is able to switch between a closed mode, a dispensing mode, and a back suction mode due to pressure differences produced. There is also a stopper (04) on which the valve membrane (02) lies in the closed mode and in the back suction mode so that the dispensing opening (03) is closed, and from which it is lifted in the dispensing mode.; The valve includes a stop ring (12), on which the encircling edge (11) of the valve membrane (02) lies as a seal during the closed mode and from which it is lifted in the back suction mode, and a lateral channel (13) thatextends axially, wherein at least parts of the encircling edge (11) are opposite the valve membrane (02), and the encircling edge (11) is movable axially on the lateral channel to switch to back suction mode, in which a gap (15) is created between the encircling edge (11) and the lateral channel (13).

Description

technical field [0001] The invention relates to a self-closing valve for dispensing flowable products. Background technique [0002] A typical application for a self-closing valve is a container in which the flowable content can be discharged by squeezing the container. So-called squeeze bottles for body care preparations are an example for this. Reducing the internal volume of the squeeze bottle by the user will increase the pressure within the squeeze bottle so that the contained product (eg liquid soap) will be delivered through the valve. Even when the container is no longer closed by means of the closure cap and even if the product acts by its weight on the outlet area of ​​the valve, the self-closing action of the valve prevents the contents from being undesirably discharged without a pressure increase. [0003] A self-closing valve for dispensing liquid or pasty products is known from DE 10 218 363 A1. The valve comprises a valve membrane which is convexly formed i...
