Definitions

  • the present invention relates to a dispensing head capable of equipping a container containing a product of liquid to pasty consistency, in particular a product cosmetic or pharmaceutical.
  • US-A-4,099,651 describes a dispensing head comprising an element tubular attached to the neck of a flexible tube.
  • the tubular element has on at least part of its length, a flat partition that protrudes from the element tubular so as to define two product outlet channels.
  • a sleeve in elastic material is threaded on the tubular element and on the part of the partition plane which exceeds.
  • the closure system consists of the edge of the sleeve of elastic material which rests on the two opposite faces of the end of said flat partition. This edge is in contact with the partition when it there is no distribution, and moves away from the partition under the push of the product. The edge returns by elasticity in contact with the faces when the distribution stops.
  • US-A-4,124,150 shows a distribution assembly comprising a obturator in the form of an elastically deformable member, subjected to action of a constraint member tending to keep this shutter applied to a seat with which it cooperates to ensure the tightness of the contact to the closing.
  • the restraining member is formed by a kind of leaf spring in relatively bulky outer projection.
  • such a system includes a number of parts incompatible with the economic constraints of the industrial environment.
  • Patent EP 0 410 858 describes a device of the same type in which the shutter is subjected to the action of a rigid constraint member.
  • a dispensing head suitable to equip a container containing a product of liquid to pasty consistency, comprising a body in which is formed a product outlet orifice and a closing member for selectively closing said orifice, said closure consisting of a member of elastically deformable material covering said orifice and able to move apart under product pressure to release the said orifice and allow the product to pass, and return to the position shutter when the pressure ceases, characterized in that said closure consists of a sleeve of which a first end is integral of the body, a second end forming a free edge, said sleeve surrounding the body and being positioned on said orifice by inverting said free edge on the body, said body being made of a rigid or semi-rigid material.
  • the configuration of the shutter in the form of an elastic member folded over a rigid or semi-rigid body contributes to self-constraining the elastic member, especially its free edge, on the body of the dispensing head, so that none no other auxiliary restraint or restraint is required to ensure satisfactory sealing.
  • the elastic member can be mounted directly on the body, or can be mounted on a mounting piece, which is mounted on the distribution head body.
  • the body made of a rigid or semi material rigid, i.e. forming a structure which is not deformable so multi-directional (extension, compression, twist) like an elastomer or equivalent, ensures good positioning of the sleeve elastically deformable, all around the body. The aesthetic is found this fact improved.
  • the opening and closing inertia is low. It offers the possibility of dimensioning the holes exactly to the desired dimension.
  • the dispensing head is formed by bi-injection, overinjection or overmolding of a first rigid or semi-rigid material forming the body, and of an elastically deformable material forming said member closing. So the head, including the shutter, is made in one molding operation. It then remains to turn the free edge of the sleeve over the rigid or semi-rigid body, and the dispensing head is ready to be mounted on a container, and used for the distribution of the product it contains.
  • said elastically deformable material is an elastomer natural, synthetic or thermoplastic, chosen from copolymers styrene butadiene, nitrile rubbers, polychloroprene or neoprene, EPDM rubber, polyurethanes, silicone rubber and ethylene-vinyl-acetate copolymers, etc.
  • the body meanwhile, is made of polypropylene, or polyethylene.
  • the head of distribution consists of a cylindrical body, comprising a side skirt one open end of which forms a free edge, said closure member being consisting of a sleeve disposed, before turning, substantially in the extension of said side skirt, said first end of the sleeve being disposed inside the side skirt, in the vicinity of said free edge. So in folded position of the sleeve, it covers the free edge of the body, which ensures at this point, when the head is mounted on a container, a seal can complete the tightness of the whole.
  • the sleeve taking support on the free edge of the side skirt of the body, is positioned perfectly by relationship to the body.
  • the body is formed of a side skirt, a portion of which is covered by the inverted part of the obturation member, said portion being in withdrawal from the rest of the side skirt so that, in the inverted position of the shutter member, this is located in alignment with the rest of the skirt lateral. This improves the aesthetics of the dispensing head.
  • the walls of the sleeve may have a thickness of between 0.5 mm and 5 mm, and preferably between 1 mm and 3 mm.
  • the free edge of the sleeve has a protrusion forming a lip which, after turning over the free edge is arranged opposite said orifice.
  • This protrusion forming a lip makes it possible to better locate the outlet of the product.
  • said closure member In the closed position, said closure member can close so sealing said orifice.
  • the member elastic In this configuration, in the closed position, the member elastic is supported on a rigid seat formed by the body all around the one or more outlet ports.
  • said closure member allows a air intake inside the container.
  • the dispensing head may include means for receiving an open neck a container with deformable walls (a tube for example). Such means may include a thread or snap bead.
  • the dispensing head comprises means for receiving a pump or valve stem, surmounting a pump or valve fitted to said pump container, a passage ensuring communication between the pump rod or valve and the outlet orifice, said body comprising a bearing surface for actuation of said pump or valve.
  • the bearing surface is located opposite the open end of the body.
  • the bearing surface is made up of a lateral portion of the body of the head.
  • a set of packaging and distribution of a liquid to pasty consistency product comprising a container containing the product and a dispensing head, characterized in that the dispensing head is in accordance with the invention.
  • the container comprises walls deformable to cause the product to exit under pressure by pressing said flexible walls.
  • the product is conditioned under pressure in the container, said container being surmounted by a valve whose actuation is controlled by the distribution head.
  • the product is pressurized at by means of a manually operated pump surmounting said container and of which actuation is controlled by the dispensing head.
  • the container consists of a flexible pocket contained inside an enclosure rigid or semi rigid.
  • the product can be a cosmetic or pharmaceutical product in the form of a milk, gel, cream, especially a moisturizer, sunscreen, makeup product, or skincare product.
  • the dispensing head 1 is designed as a push button suitable for mounting on a valve stem or pump.
  • the push button comprises a cylindrical body 2 of axis X, rigid, formed of a side skirt 8 of which a first end 3 is closed by a slightly inclined wall 4, forming a bearing surface for actuation a valve or pump.
  • the body 2 has a central chimney 5 of which the section is suitable for allowing the push button to be force-fitted on a valve or pump rod.
  • the central chimney 5 defines an axial passage leading to a passage 6, arranged substantially perpendicularly at the axial passage.
  • the passage 6 leads to an outlet orifice 7 formed in the upper part of the side skirt 8 of the body 2.
  • the side skirt 8 has at its end 9 opposite the bearing surface 4, a free edge 10.
  • the push button includes a sleeve of elastomeric material 11, one of which end 12 is integral with the inner surface of end 9 of the skirt side 8.
  • the connection of the body and the sleeve 11 may be located in an area other than that illustrated in this embodiment.
  • the sleeve 11 and the body 2 are produced by bi-injection or superinjection of two compatible materials capable of melting to form physico-chemical bonds.
  • the body is made of polypropylene or polyethylene.
  • the sleeve 11 is formed of a material elastomeric such as a copolymer of ethylene propylene and a diene (EPDM).
  • the internal surface of the side wall 8 forms, on the area of connection of body 2 and sleeve 11, a slight setback so as to what the sleeve does not cause an excess thickness compared to the surface internal side wall 8.
  • the thickness of the wall of the sleeve 11 is of the order of 1 mm to 2 mm.
  • the sleeve 11, resulting from the molding, is located substantially in alignment with the internal surface of the side skirt 8 (see FIGS. 1A and 1C).
  • Sleeve 11 has a free edge 13, a portion of which forms a lip 14 which, when the sleeve is folded over body 2, like a "sock" (see Figures 1B and 1D), comes opposite the orifice 7 so as to close it.
  • the lip is designed so that in the closed position it take support on a rigid part of the body located all around the orifice 7.
  • the body 2 of the head distribution 1 is, in the vicinity of the bearing surface 4, of slightly cross section greater than the section of the rest of the side skirt 8 so that, in position returned from the sleeve 11 on the body 2, the sleeve is substantially in the extension of the lateral edge 15 of the bearing surface 4.
  • the mold is first of all body 2. Then, the sleeve 11 is over-injected or overmolded. return; manually or mechanically, the sleeve 11 on the body 2 of so that the lip 14 closes the orifice 7.
  • the dispensing head is then ready to be mounted on a tank fitted with a valve or pump, or on a tube or other container with deformable walls. It is evident that others means could be used to secure the sleeve 11 of the body 2. As for example, this operation could be carried out by gluing or welding.
