Embodiment Construction

[0036] A preferred embodiment of the dispensing closure according to the invention will now be described with reference to the drawings.

[0037] figure 1 and 2 A fluid container 3 is shown with a dispensing closure 2 according to the invention mounted thereon. The combination of the container and the closure installed is designated with the general number 1.

[0038] The container 3 may contain a free-flowing product, such as a lotion, cream, perfume or the like, and is typically provided with a neck with an outlet opening. The container can be constructed of a solid material, such as glass or ceramic, or plastic, whereby the walls of the plastic container can be rigid or flexible. The neck of the container 3 may be provided with threads to allow a spray top to be fitted to the neck in a manner well known in the art.

[0039] The dispensing closure 2 basically corresponds to a plug that can be fitted in the neck of the container 3 in order to seal the container 3 in a liq...

Abstract

A valve-controlled dispensing closure (1), suitable for a container (3) containing a fluid, fits snugly to the neck of the container to ensure liquid-tightness of the container, comprising: a plug body (23), arranged to be inserted into the neck of the container , with a central fluid channel and a peripheral air channel; a double-valve diaphragm (22), made of a flexible elastic material, arranged in a recess provided on the upper part of the plug body (23) to cover the fluid and air channels; the plug cover ( 21), sealing the double valve diaphragm (22) inside the plug body (23), having one or more slots arranged annularly and axially aligned with the air passage of the plug body (23), and having The central fluid channel of the plug body (23) is axially aligned with the central orifice. The double valve diaphragm (22) comprises a first valve section which is a normally closed valve (22d) having a slit-type central orifice (22a) and which seals the central fluid passage of the plug body (23) when in the rest position and is normally closed. The umbrella valve (22b) closes the valve and seals the second valve section of one or more slots of the plug cover (21) when in the rest position.

Description

technical field [0001] The present invention relates to dispensing closures for dispensing liquids such as perfumes from open containers.
