Definitions

• the present invention relates to a liquid or powdery fluid dispenser comprising a reservoir provided with at least one deformable actuating wall and a dispensing orifice.
• a liquid or powdery fluid dispenser comprising a reservoir provided with at least one deformable actuating wall and a dispensing orifice.
• This type of dispenser can for example be used in the fields of perfumery, cosmetics or even pharmacy for dispensing liquids or powders.
• dispensers of this type already exist in the prior art, using the deformation capacity of a part of the reservoir to put the fluid product that it contains under pressure so as to discharge it through a dispensing orifice.
• a rigid dispensing piece is preferably inserted between the two sheets: this dispensing piece advantageously forms the dispensing orifice.
• a spring can be placed between the two sheets to perform the elastic return function. In this document, it is even planned to close the dispensing orifice while the spring is compressed to its maximum state.
• a particularly flat fluid dispenser which can for example be included inside the magazine as a free sample.
• the present invention aims to remedy this aforementioned drawback of the prior art by defining a relatively flat distributor whose spring means are not compressed or at least very weakly when a flat pressure is exerted on the distributor .
• the distributor must for example be able to be included in magazines without the risk of compressing the spring means too strongly.
• the present invention provides that the dispenser comprises a body defining a frame having a defined thickness so as to delimit a defined inscribed volume, said actuating wall extending over said frame and being able to be deformed so as to decrease the volume of the tank and enter the volume entered.
• the present invention provides that the dispenser is provided with return spring means for urging the actuating wall in a rest configuration defining the maximum volume of the reservoir. It is then advantageous for the spring means to be formed in a single piece by the body already forming the frame. One can for example make the body of plastic.
• the spring means extend inside said frame.
• the spring means can even extend in the rest position inside said inscribed volume.
• the spring means may extend in the rest position outside said inscribed volume.
• the spring means do not stress the actuating wall or walls in the rest position. It is only after having pressed on the walls, that the spring means return the actuating wall or walls to the rest position.
• the spring means when the spring means extend outside the inscribed volume, they urge the actuating wall or walls, even in position rest. This will result in a bending of the actuating wall at the level where the spring means are in contact with the wall.
• the spring means can comprise at least one flexible blade which extends across said frame.
• the frame may for example have a constant thickness of the order of two to four millimeters.
• the dispenser can comprise two actuating walls defined by two flexible sheets fixed in leaktight manner on either side of said frame.
• the frame is substantially non-deformable.
• the frame can be substantially in the form of a ring.
• the dispensing orifice is formed by the frame, advantageously on its periphery.
• FIG. 1 is a perspective view of a fluid dispenser according to the invention
• FIG. 2 is an exploded view of the dispenser of FIG. 1,
• FIG. 3 is a view in horizontal cross section through the dispenser of FIG. 1,
• FIG. 4 is a view in vertical cross section through the dispenser of FIG. 1, and
• Figure 5 is a view similar to that of Figure 4 for an alternative embodiment of a dispenser according to the invention.
• the fluid dispenser used to illustrate the present invention comprises three constituent elements, namely a body 1 and two flexible sheets 2.
• the dispenser may further comprise a piece of porous material 3.
• the body 1 comprises a frame 10, preferably substantially non-deformable, which forms a closed loop on itself.
• the frame here is substantially circular, but it could also be polygonal, for example triangular, square, pentagonal, hexagonal, etc.
• the frame 10 forms a dispensing head 13 which is integrated into the frame.
• the head 13 breaks the circularity of the frame 10 so as to impart a drop-shaped appearance.
• the frame 10 defines a peripheral surface 11 which is here substantially cylindrical.
• the frame 10 further forms two substantially planar edges 12, but of annular shape. Each edge 12 may for example be provided with a welding rod 121 which forms a projection around the entire periphery of the frame 10.
• the dispensing head 13 defines a dispensing orifice 14 which establishes communication between the inside of the frame and the outside of the frame.
• the dispensing orifice opens out at the peripheral surface 11. This is more visible in FIGS. 3 and 4.
• the dispensing head 13 optionally forms an insertion housing 15 intended to optionally receive the piece of porous material.
• 3 which can advantageously be configured with an insertion appendage 34 intended to be forcibly inserted into the housing 15.
• the piece of porous material 3 extends freely from the appendage 34 inside the frame 11 by forming a body 31, of course, made of porous material.
• this piece of porous material 3 is to imbibe or impregnate with fluid, liquid or pulverulent product so that the dispensing orifice 14 is always supplied with fluid.
• a piece of porous material 3 can be dispensed with in certain application cases, and in particular when the fluid product is pulverulent.
• This frame 11 has a defined thickness which corresponds to the height of the peripheral wall 11. In the example used for the present invention, this thickness is constant over the entire periphery of the frame 11. It is however possible imagine that this thickness varies locally.
• the body 10 is at least undeformable in the direction of the thickness of the frame 11. In other words, the thickness of the frame 11 cannot be altered or modified even when subjected to significant pressures.
• the frame 11 can be deformable in the direction of its width so that the loop or the ring can be slightly deformed. However, preferably, the ring is also non-deformable.
• the frame 11 defines an inscribed internal volume Ni which is equal to the surface defined by the interior of the frame 11 multiplied by the thickness of the frame 11. This corresponds to the volume of the frame when it is placed between two perfectly flat surfaces . Since the thickness of the frame is undeformable or unalterable, this inscribed volume Ni is constant and defined.
• the body 10 can also form in a single piece return spring means, which are here in the form of two flexible blades 16 which extend transversely in the frame 11.
• One blade 16 can be concave while the other can be convex as can be seen in Figure 2.
• the two blades 16 can be fully inscribed inside the volume Ni, as shown in Figure 4.
• the blades 16 can extend at least partially outside the Ni volume, as shown in Figure 5.
• the body 1 is associated with two flexible sheets 2 which are attached and fixed in a sealed manner on either side of the frame 11.
• the two sheets 2 are preferably heat-sealed on their periphery at the level of the rod welding 121 formed on the two edges 12 of the frame 11.
• a sheet is first welded to the frame 11 so as to form a container. Fluid product can thus be introduced into this container. Then, it suffices to weld the other sheet 2 to seal this container and thus form a reservoir 17.
• the volume entered Vi is different from the internal volume of the reservoir 17.
• the volume Ni is equal to the internal volume of the reservoir 17 when the dispenser is at rest.
• the sheets 2 are pressed so as to bring them together, the blades 16 are deformed and the internal volume of the reservoir 17 is reduced, which is then less than the volume entered Vi.
• the internal volume of the reservoir 17 is greater than the volume entered Vi in the rest position, since the blades 16 protrude in the rest position out of the volume Vi.
• the volume of the reservoir 17 would only be equal to the volume Vi only in the case where the distributor would for example be arranged between two flat surfaces so as to bring the blades 16 back inside the volume Vi. We then find our in the configuration of Figure 4, with the difference that the blades 16 are then partially constrained.
