- the metering-pouring spout comprises a tubular or similar element 9 made of an at least partially transparent material carrying graduated level marks and the longitudinal axis x-x 'of which can be either straight line, as illustrated in FIG. 1, either curved, as shown diagrammatically in FIG. 2.
- the tubular element 9 has a first open end 10 which is made integral with the support plate 2.
- the attachment may result from a one-piece production, for example by molding, or from an added connection between the element 9 and the wall 2, by gluing or the like, or of a casing of a male part 10a_ of
- the tubular element 9 is provided to surround the opening 3, so that its axis ⁇ - ⁇ 'passes through this opening, making, with the plane of the wall 2, an angle ⁇ , preferably acute, possibly between 0 and 90.
- the opening 3 is made as close as possible to the periphery of the wall 2 and the tubular element 9 is present, preferably, a length chosen as a function of the angle ⁇ , so that its second open end 11 remains included in projection at the size section of the plug 5.
- the same support wall 2 could comprise more than one opening 3 each surrounded by a tubular element 9 with which each would constitute a metering-pouring spout.
- the second open end 11 of the tubular element 9 is associated with a shutter 12 capable of closing this end 11 to delimit, by the internal volume of the tubular element 9, a metering chamber 13 communicating, permanently, with the volume useful 14 of the container 4 through the opening 3.
- the shutter 12 is of the valve type, with elastic return and direct or trigger operated, and is carried by the tubular element 9.
- the valve shutter includes, as this is illustrated in fig. 1 and 4, a sealing plate 15, in any suitable rigid material, 'which is mounted on the tubular element 9 by a part 16 assuming a hinge or articulation function, as well as an elastic return function of the obturator in a closed position of the chamber 13.
- the part 16 may advantageously be constituted by a leaf spring formed by or attached to the tubular element 9 and the plate 15.
- the shutter 12 comprises a seal 17 attached to the face of the wafer oriented towards the open end 11.
- the seal 17 is preferably constituted by a skin 18 covering and holding a cushion in place. pad or the like 19 for padding.
- a cushion or The tampon can advantageously consist of a mass of foam of suitable material or, alternatively, a capsule or a charge of a liquid or gaseous product.
- the seal 17 is intended to cooperate with a seat 20 presented by the open transverse end 11 in the form of a continuous peripheral edge originating, for example, from the presence of a chamfer 21.
- the edge 20 is limited by a plane, so as to constitute a support seat capable of cooperating, under the best conditions, with the lining 17.
- the lining of seal 17 is pressed against the seat 20 which is partially imprinted in the thickness of the pad 19 through the skin 18 by establishing a peripheral seal isolating the metering chamber 13 from the ambient medium.
- the tubular element 9, constituting the metering-pouring spout can have, in cross section, any suitable shape, such as a circular shape illustrated in FIG. 5.
- the tubular element 9 can have a curvilinear triangular shape with rounded vertices, as illustrated by FIG. 6.
- the opening 3 cleans, in the support wall 2, a weir threshold 22.
- the weir threshold 22 is formed so that the opening 3 has the lowest useful section of passage at right of this weir for reasons which emerge from the following.
- the latter can therefore largely surround the opening or, on the contrary, border it peripherally.
- the spout described above is used in the following manner.
- the user directs the tubular element 9, as illustrated by the Fig. 1, then subjects the container 4 to tilting by rotation in the direction of the arrow f .., until the mass of product P_ is established at a level higher than that of the weir 22. In this way.
- the product _P flows into the chamber 13 which is closed by the shutter 12.
- the user After emptying the dose _D, the user ceases its action in the direction of the arrow f 2 and lets escape the obturator plate 15 which is briskly brought back, by the action of the spring 16, against the seat 20.
- the shock back of the wafer 15 in the closed position of 'the chamber 13 causes detachment of the product adhering either the seat 20 or to the skin 18 or to the tubular element 9. in this way, a seal may be established without particular attention on the part of the user, only, compelled to exercise a gesture of tilting, opening and releasing the shutter to obtain a precise dose distributed without risk of retention.
- the particular shape of the weir 22 has the consequence of delimiting an opening 3 having a useful passage section reducing to the right of the weir 22.
- the product P_ is required to borrow the widest cross-section of the opening 3, which enables rapid, efficient filling of chamber 13 to always have a precise dose.
- This dose can be adjusted, after filling as said above, by tilting the container 4 in the opposite direction to the arrow f., To bring a return flow of the product JP between the chamber 13 and the volume 14.
- the product P, admitted into the chamber 13 can be transferred back by " being forced to take the smallest useful passage section of the opening 3.
- Fig. 8 shows an advantageous arrangement consisting in causing the wall of the tubular element 9 to have a local constriction 40 situated in the part of the peripheral wall opposite the overflow threshold 22.
- the constriction 40 is preferably formed by a part 40a of slight inclination, marked from or substantially close to the base of the tubular element 9 surrounding the opening 3.
- the part 40a delimits, inside the chamber 13, a convergent 41 whose cross section useful is gradually reduced to the connection area with a part 40b of greater reverse inclination.
- This part 401) household, inside the tubular element 9, a divergent 42 opening in the direction of the cross section 11.
- the part 40b is located substantially in alignment with the weir threshold 22, in consideration from a direction y perpendicular to the plane of the support wall 2.
- the function of the throttle 40 is to constitute, after the first filling tilting according to FIG. 9, a shoulder slowing the return of the product constituting the dose D when the container is tilted back, illustrated in FIG. 10.
- This braking in collaboration with the overflow threshold 22, makes it possible, instantaneously and without precaution, to make a precise adjustment of the dose that the user wishes to constitute in the chamber 13.
- An exemplary embodiment is shown in FIG. 11, in which such metering adjustment means, designated by the reference 50, involve a tubular segment 51 mounted free to slide telescopically on the tubular element 9.
- the segment 51 can be immobilized axially by means of a blocking member 52, such as a needle screw, passing through the tubular segment 51 to cooperate with an axial groove 53 presented by the tubular element 9.
- a sealing bellows 54 is then fitted between the segment 51 and the element 9 to isolate the metering chamber 13 from the ambient medium.
- FIG. 12 shows another embodiment of the means 50 constituted, then, by a part 60 of the periphery of the element 9 made of a deformable material capable of occupying, that is to say an outward position, as illustrated in mixed lines, that is to say an inward position, projecting inside the useful volume of the chamber 13 which is reduced accordingly.
- the transition from one to the other position can be acquired by a pressure action tending to cause a bistable link to be elastically deformable, thus conferring a kind of memory on the deformable wall part 60.
- Fig. 1 shows, in phantom, an alternative embodiment chosen to allow stacking despite the projecting part that constitutes the element 9.
- the element 9 is covered by a plug 70 made integral with the plug 5 by any means known fixing.
- Fig. 13 shows an application of the metering-pouring spout to a container 70 - of capacity close to or greater than that of the domestic containers taken into account previously.
- the container 70 is, for example, mounted to rotate on an axis 71 while being driven manually or motorized.
- the container 70 constitutes a reservoir, refillable or not, into which a quantity of product has been introduced to occupy a volume less than that useful of the reservoir.
- the rotation of the container is provided in the direction of arrow f, for reasons which emerge from the following.
- the container 70 comprises, on its peripheral wall and preferably near one of the transverse walls, at least one metering-pouring spout according to the invention and as described above.
- the container 70 has an intermediate capacity 72, part of which delimits it constitutes the wall 2 on which the tubular element 9 is adapted.
- this application is provided.
- the tubular element 9 is oriented outside the transverse wall such as 73, so as to allow cooperation between the shutter 12 and a stop or the like 74 in a fixed position. From a state such as that shown in phantom in FIG. 14, the pulverulent product fills the capacity 72 occupying the low position. The rotation in the direction of the arrow f, brings the capacity 72 progressively in the high position according to a circular trajectory which promotes the filling of the spout 1. This operating phase is equivalent to that described in FIGS. 7 to 10.
- the tubular element 9 In the high position, the tubular element 9 is completely filled and its emptying can take place manually or automatically by cooperation between the cover 12 and the stop 74.
- the spout 1 For each rotation turn of the reservoir 70, the spout 1 is capable of delivering a dose of product emptied into a hopper or other filling container.
- the container 70 can comprise several capacities 72 equipped with spout 1 and arranged equidistantly or not angularly. It can also be provided to provide the container 70 with a fixed or mobile internal mixer promoting the mixing of the product during the rotation of the container 70.
- a fixed or mobile internal mixer can be constituted by an arm, a hoop, a stirrup, etc. ..
- the container 70 can be of any kind and appropriate shape and can be adapted to a fixed or mobile station, whether or not part of a treatment, packaging, mixing or use installation of the pasty, pulverulent or granular product.
- Fig. 15 shows another variant according to which the overflow 22 is bordered by a bar or a blade 75 intended to scrape the product to promote filling of the spout, more particularly but not limited to, in an application where the container consists of a rotating tank 70 .
- the invention finds an advantageous application in The packaging of containers for powdered food products.
