Definitions

  • the present invention relates to a device for packaging and dispensing in spray form a fluid product. More particularly, the invention relates to a miniature sprayer, preferably disposable, suitable for packaging in the form of a sample of cosmetic products, especially perfumes.
  • the product is preferably liquid, but may also be in the form of a small particle size powder.
  • the samples are not generally intended for sale, their manufacturing cost must be as low as possible. It is therefore important to have devices whose parts are easily achievable in large series and whose assembly can be performed in a simple manner. In addition, they must be able to generate a spray whose quality is as good as possible, and whose characteristics are as constant as possible.
  • One solution for producing such packages at a cost as low as possible would be to make the container in the form of a pod of the type that is commonly used for the packaging of certain physiological serums, eye drops or makeup removers.
  • a pod is made in one piece with a spray orifice whose opening is caused by tearing a tip, in particular by a twist of the tip around the axis of the orifice.
  • the filling of such a device can be done via the open bottom of the container. The latter is then closed, in particular by welding, in the manner of a tube.
  • the welding operation after filling the container, especially when it is a highly volatile product such as a perfume, is not without problems. Under the effect of heat, the product may evaporate, deteriorate or even ignite.
  • a device for spraying a fluid product comprising a container with compressible walls, a first end of which defines a first opening, closed after filling the product, and a second end of which is closed and is capable, prior to the first use of the device, to be opened so as to disengage a second opening through which the product can be dispensed, the device further comprising an insert disposed inside the container, said insert delimiting a spray port in communication with the product and disposed opposite the second opening, the insert being configured to isolate the product of the first opening prior to the closure of the latter.
  • the portion of the insert intended to isolate the product of the first opening is at a non-zero axial distance from said first opening, thus first allowing the product to be isolated. opening, then close the latter. This is not the case if the portion intended to isolate the product from the opening, is also used for closing said opening.
  • both the spray orifice and the dimensions can be selected as accurately as possible. Therefore, the quality of the spray is consistent with what is desired, and constant from one device to another.
  • the insulation is made between the product and the filling orifice, which allows, where appropriate, ensure that it is heat-sealed without risking evaporation or deterioration of the product.
  • the spray orifice is in fixed axial position inside the container. This gives a much better accuracy in spraying the product.
  • the assembly of the assembly is simplified to a large extent. The cost price is also reduced substantially.
  • the first end of the container is located opposite the second, along a longitudinal axis X of the device.
  • This alignment of the insert along the axis X of the device facilitates to a large extent the assembly and filling of the device according to the invention.
  • the insert forms an interior volume in communication with said spray orifice, an external volume, in communication with the interior volume, being delimited between the insert and the container.
  • said insert may be configured in the form of a tubular element whose first end is closed and of which a second end, opposite to the first, is traversed by said spray orifice, at least one window being formed in a wall said tubular element so as to ensure communication between the interior volume and the external volume.
  • the window can be arranged as close as possible to the spray orifice so as to ensure as complete emptying of the container as possible.
  • the side wall comprises two windows arranged diametrically opposite on said side wall.
  • the first opening is delimited by a frustoconical portion of the container with compressible walls, and whose section increases in the direction of the first opening.
  • said tubular element is preferably of frustoconical shape at least over part of its height in engagement with said frustoconical portion of the container, so as to apply sealingly thereto.
  • the insert is frustoconical throughout its height.
  • the first opening is preferably closed by welding, especially thermal or ultrasound, or by bonding.
  • This technique is commonly used for the closure of packaging in the form of tubes, as commonly used for the packaging of gels, creams care or sun products.
  • the insulation made by the insert between the product and the opening allows, when the latter is to close hot, substantially reduce the risk of evaporation, deterioration, or ignition of the product.
  • the container is obtained by molding, in particular by extrusion blow molding, the second opening being closed by a portion integrally molded with the container, and torn off, in particular in response to a twist around the axis of said second opening.
  • the container may be formed of a thermoplastic material, in particular a low density polyethylene.
  • the insert may also be formed in one piece obtained by molding, and in particular by roto molding, a thermoplastic material, such as polyethylene or polypropylene.
  • a thermoplastic material such as polyethylene or polypropylene.
  • the insert can be obtained by assembling two or more pieces, in particular molded separately.
  • the container has a portion of substantially spherical shape between said first and second ends. This configuration helps to create a sufficient volume inside the container, so that the latter can contain the desired amount of product. In addition, it promotes the proper and uniform pressurization of the container, and the spraying of the product in good conditions.
  • the spray orifice may be formed in an end wall of the insert, an inner surface of said wall being hollowed out with a plurality of vortex channels opening onto said spray orifice.
  • Channels of this type are common in nozzles used in particular in certain aerosol or pump devices. These channels make it possible to accelerate the product in the vicinity of the spray orifice, and to improve the quality of the spray.
  • the device according to the invention can be used for packaging and dispensing a sample dose of a cosmetic product, in particular a perfume.
  • FIGS 1 and 2 to which reference is now made illustrate a first embodiment of the device 1 according to the invention.
  • It comprises a container 2, obtained by extrusion blow molding of a low density polyethylene.
  • the container comprises a spherical body 3.
  • the spherical body 3 is in communication with a slightly frustoconical end portion 4 ending in an opening 6, closed by a tip 5, the tearing off of which can be obtained by twisting it around the X axis of the end portion 4.
  • the spherical body 3 is also in communication with a second end portion 7, diametrically opposite to the end portion 4.
  • the end portion 7 is also frustoconical in shape and has a free edge defining an opening 8.
  • the device 1 also comprises a tubular insert 10 of frustoconical shape.
  • the end 11 of larger section of the insert 10 is closed by a transverse wall 12.
  • the other end 13 of the insert 10 is closed by a transverse wall 14 traversed at its center by a spray orifice 15 with the characteristics, in particular dimensional, are chosen according to the characteristics sought for the spray.
