The present invention relates to a dispensing head. It also relates to a dispenser equipped with such a head.
Such a head allows a user to dispense a fluid (liquid, gel, etc.). The field of the invention is more particularly, but not limited, to that of dispensers of cream, soap, cosmetics, medical packaging or food products.
Various devices are known for dispensing liquids.
A first problem of this type of device lies in its lack of simplicity of use and in its ergonomics. For example, you have to squeeze a reservoir (tube-type of cream) to get out liquid and the liquid must be collected with a finger far from the pressure zone. Thus, it is not always easy to use such a device with one hand.
A second problem of this type of device lies in its complexity of implementation. For example, such a device can sometimes comprise too many parts to assemble and/or at least one piece that is not easy to insert among the constituent elements of said device.
The object of the present invention is to solve at least one of the above-mentioned problems.
This objective is achieved with a dispensing head, comprising:

With reference to
Such a head 101, 102, 103, 104 is arranged to dispense at least one fluid (this fluid typically comprising a liquid or a paste-like substance gel or cream).
The cap 32 comprises an outer wall 34 (39, 40).
The outer wall 34 comprises side walls 39 and an upper wall 40.
The outer wall 34 comprises (on its side walls 39 and/or its upper wall 40) at least one referred to as the shell part 35.
The outer wall 34 comprises (on its side walls 39 and/or its upper wall 40) at least one referred to as the pressing part 37 made of a more flexible material (typically a thermoplastic elastomer (TPE) or a copolymer of octene and ethylene) than the material (typically polypropylene (PP)) of the at least one shell part 35.
Each pressing part 37 may also comprise a thinner polypropylene (PP) wall of the order of 0.1 mm to 0.3 mm which may optionally be covered with an external overmolding of flexible material.
Each pressing part 37 preferably comprises a rib 371 (illustrated for example in
In the present description, “ flexible matter ” or “ flexible material ” will be understood to mean any material that is more flexible or less hard than the material of the at least one shell part 35 (the two hardnesses compared being measured in a same unit among Shore A or Shore D).
The pressing parts 37 and the shell parts 35 of the cap 32 are joined in one part obtained by bi-injection or overmolding. In a variant not shown, the pressing parts 37 and the shell parts 35 of the cap 32 are two separate parts inserted into one another, for example a flexible “ sock ” 37 inserted into a shell 35.
The cap 32 comprises at least one outlet 24 on the outer wall of the cap 32. The outlet 24 is the outlet of the part forming the cap 32 and leading to the outside of the cap 32. Optionally, an intermediate piece may be disposed between the outlet 24 and the outside of the dispensing head according to the invention, like, for example, an accessory (preferably mobile) such as a rotating dispensing ball (or “ roll-on ” in English) or a brush.
The cap 32 comprises an insertion orifice 33.
The cap 32 and the stopper 23 are arranged so that the stopper 23 is mounted in the cap 32 according to an insertion arrangement in the cap 32 on the side of the insertion orifice 33 and in an insertion direction 25.
The stopper 23 is mounted inserted in the cap 32, being held in the cap 32 and can exit the cap 32 and re-enter the cap 32 through the orifice 33.
The side walls 39 extend:
The side walls 39 form a tube extending in the insertion direction 25 or substantially in the insertion direction 25.
By “ substantially ” in the insertion direction 25 it is meant:
The tube formed by the side walls 39 has two ends:
The stopper 23 is held by a tightening force exerted by the cap 32 (more exactly by the side walls 39) around the cap 23 in the form of tightening forces perpendicular or substantially perpendicular to the insertion direction 25.
In addition, there is preferably flexible material 51 (in the same material as the part or parts 37) interposed in an intermediate zone 36 situated between the rigid part 35 and the stopper 23 is preferably provided. This makes it possible to improve the sealing and/or reducing visible deformations outside the cap 32.
Preferably, this flexible material 51 is part of the cap 32, is located under the rigid part 35 and is manufactured (during the bi-injection) at the same time as the pressing part(s) 37.
The stopper 23 is equipped with connection means (clipping means, no screws, etc.) having at least one reservoir or tube 17;
In all embodiments of dispensing head according to the invention 101, 102, 103 or 104 which will be described later, this dispensing head comprises at least one assembly, each assembly comprising:
For at least one or for each assembly, the dispensing orifice 205 of this assembly is located on a side wall of the dispensing pipe 8 of this assembly, so that the dispensing orifice 205 of this assembly, the dispensing pipe 8 of this assembly and the dispensing valve 5 of this assembly are arranged so that the fluid of this assembly travels globally (that is to say on a larger scale than the swirls of the fluid microparticles) at a right angle or substantially a right angle passing from the pouch 2 of this assembly to the dispensing pipe 8 of this assembly, that is to say between the direction of the fluid at the inlet of the dispensing valve 5 of this assembly and the direction fluid at the outlet of the dispensing valve 5 of this assembly.
It will be noted that in all the figures and embodiments described, the dispensing valve 5, 5a, 5b (movable between its closed and open positions) is, in its closed state, kept pressed (sufficiently firmly, by means of return means or a return spring of the valve 5, 5a or 5b for example as described in the patent WO2012/010793) against a stationary part (called dispensing seat 70, which surrounds at least partially the periphery of the dispensing orifice 205 associated) and “rigid ” (ie not made of flexible material) of an inner wall of the dispensing pipe 8, 8a, 8b respectively in which it is housed. More specifically, the dispensing valve 5, 5a, 5b respectively comprises a membrane which, in the closed state of the dispensing valve, is kept pressed against the dispensing seat 70, and parts from this seat in its open state. It should further be noted that the dispensing seat 70 is a lateral part of the dispensing pipe 8, 8a, 8b respectively, that is to say that this seat 70 is limited to one face, preferably one plane, of a internal wall of dispensing pipe 8, 8a, 8b respectively, and does not all around a section of the dispensing pipe 8, 8a, 8b respectively which would be realized in a plane perpendicular to the direction of elongation of the pipe 8 , 8a, 8b respectively.

This unique piece 12 is monoblock. The junction element 11 typically has a hardness of 70-80 Shore A. One hole creates a passage between the dispensing pipe 8 of this assembly and the feed pipe 6 of this assembly without passing through the pouch 2 of this assembly. The junction element 11 plugs this hole and is held by tightening in this hole.
Once the head 101, 102, 103 or 104 installed within a dispenser according to the invention, each inlet 38 of an assembly is connected to a fluid reservoir 17 which is specific to this inlet 38 and which preferably comprises the fluid of this assembly.
