BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a push-button applicator device for dispensing liquids which can be coupled with a dosing pump or aerosol valve on the mouth of a liquid container, the device allowing dispensing of liquids in a uniform and controlled way on a surface by a spongy material portion, thereby providing a safe system which can prevent spilling of the liquid during transport and storage.
DESCRIPTION OF THE RELATED ART
Applicators with sponges are normally used with liquid products, typically for cleaning and preserving footwear and eyeglasses, wherein a uniform dispensing of the same on a desired surface is required.
A push-button applicator device for dispensing liquids, including devices which are mounted on the dosing pump or aerosol valve located at the mouth of a liquid container, is put forth, for example in EP 0 374 339 B1, wherein the push-button applicator disclosed is mounted on the discharge tube of a dosing pump. The applicator comprises a spongy material part fixed to the top surface of a push button and a peripheral skirt which starts from a top surface and extends towards the container in such a way that, during operation, the push-button applicator slides perimetrically over the neck of the pump-container unit to which it is coupled. The applicator does not become detached due to a ring-shaped widening disposed therein. The spongy material part of the push button is protected by a closure cap that adjusts directly on the push button.
The push button described in EP 0 374 339 B1 moves toward the container upon being pressed upon, whether or not the closure cap is in place, thus actuating the tube which emerges from the dosing pump, whereby a liquid discharge impregnates the top applicator sponge. With this type of push-button applicator, any accidental pressure exerted on the closure cap during transport or storage, e.g., in a bag, is passed on to the discharge tube of the dosing pump and thereby causes inadvertent operation of the same, with the subsequent risk of losses of product and damage to objects and places where the uncontrolled spilling occurs.
SUMMARY OF THE INVENTION
The present invention seeks to overcome the above inconveniences and disadvantages by providing a push-button applicator device for dispensing liquids. The present invention comprises a push-button applicator device for dispensing a liquid from a container (10) having a mouth, a liquid outlet means (8) disposed at the mouth, the mouth being enclosed by the liquid outlet means (8), the liquid outlet means including a discharge tube (17) that extends from the liquid outlet means (8), the discharge tube (17) being displaceable between a first position corresponding to a closed state and a second position corresponding to a discharge state. The push-button applicator device includes at least one fixed part (7), a movable part (4), and a cap (1).
The at least one fixed part (7) includes a proximal portion including fixing means for attaching the fixed part (7) to the liquid outlet means (8) by clasping the liquid outlet means (8) horizontally, the proximal portion having a second outside diameter, and a distal portion which perimetrically surrounds the entire length of the discharge tube (17) when the discharge tube is in the first position, the distal portion having a third diameter.
The movable part (4) is adapted for telescopic movement with respect to the fixed part (7) between the first position and the second position. The movable part (4) includes a proximal portion having a second outside diameter; a distal portion comprising a flat distal surface (3); a spongy material part (2) adhered to the flat distal surface (3); a perimetric skirt (5) extending in a proximal direction from the flat distal surface (3), the perimetric skirt (5) having a first outside diameter, wherein the first outside diameter is smaller than the second outside diameter of the proximal portion of the fixed part (7), and wherein the third diameter is smaller than the first outside diameter of the pe
