Problems solved by technology

[0006] Although pumps or valves are equipped with such devices that keep the bottle watertight, this unsatisfactory sealing at the nozzle is not good for the product, especially in the field of pharmaceuticals and cosmetics
[0007] More specifically, this problem concerns the volume of product that remains wasted in the aforementioned duct of the nozzle between two successive shots
In addition, traditional nozzles cannot achieve such a spray: for different flow rates, pressures, spray angles, from the beginning to the end of the product dose restitution (restitution), the spray is constant and independent of the manual extrusion speed
[0008] This discontinuity is detrimental to the comfort of the user and, when the product is a drug, to the absorption of the product

Embodiment Construction

[0030] The nozzles shown in Figures 1 to 4 show a conical shell 5 with a central axis at least in its upper part defining a wall of an inner tube 50 upwards through a small diameter spray hole 50a. Opens outwards and extends downwards through the inner sleeve 51 .

[0031] As shown in Figure 2, the housing 5 has a lower outer skirt 52 covering the neck of the bottle.

[0032] As also shown in FIG. 2 , advantageously, a removable cover C can cover the upper part of the housing 5 .

[0033] The housing 5 of the nozzle has a recessed outer area 53 located close to its fixing means for fixing to the end of the spout tube E and enabling manual pressing of the nozzle to actuate the product dispensing device.

[0034] The nozzle also comprises a valve housed in the tube 50, which valve has a needle 1 whose upper end 1a cooperates with the outlet 50a of the turbulence chamber 54, thus forming the ejection nozzle.

[0035] Thus, the end 1a has a pin whose profile matches that of the ...

Abstract

The invention concerns a push-button nozzle for liquid or semi-liquid product dispenser, said dispenser comprising means (P) for delivering the product under pressure which are mounted on the product container bottle and which comprise an ejection tube (E) projecting outside. The invention is characterized in that said nozzle comprises a needle valve (1) tightly closing the spraying orifice (50a) provided at the end of said nozzle, means for being fixed on the ejection tube and means for supplying products to a turbulence chamber located proximate said orifice.

Description

technical field [0001] The invention relates to a nozzle for liquid or semi-liquid products. [0002] More particularly, the present invention relates to a nozzle mounted on a dispenser of a pharmaceutical or cosmetic product, such as a nasal spray. Background technique [0003] The known nozzle generally consists of an external projection at its lower part provided with a collar forming a button, an inner tube at its upper part providing an end nozzle and at its lower part connected to the spray tube of a device that is mounted on Used in the neck of a bottle containing a product to deliver the product under pressure, such as a pump or valve. [0004] However, such nozzles have the disadvantage of not including their own sealing means. [0005] In fact, the duct formed inside the nozzle for conveying the liquid from the end of the discharge pipe upwards to the outlet of the nozzle does not have any type of element capable of ensuring a temporary closure.
