Definitions

  • the invention relates to a new pressurized device for the distribution of products liquids or creams, such as for example cosmetics, foodstuffs, pharmaceutical.
  • a pressurized device consists of a container body, on which possibly comes to fit a cover; on the neck of this container is crimped a valve via a valve holder cup, a distribution means connected to the valve is provided; the container body and the cup define a reservoir cavity; the valve consists of a valve body, a valve control rod which passes through the valve body, a seal and a return system that presses the control rod valve against the seal, the assembly being held in place by crimping the valve holder cup; the valve control rod is surmounted by a push button.
  • the reservoir cavity are arranged a product to be dispensed and a means of propulsion.
  • the means of propulsion can be a compressed gas directly in contact with the product in the container body.
  • a plunger member is attached to the valve.
  • a flexible bag we are often faced with compatibility problems with the formula and strength of the material constituting the bag, which must be flexible and waterproof that time. If we use a piston to separate the gas from the product, we are faced with sealing problems along the contact surfaces between the piston and the inner wall of the container body.
  • the filling orifice of the gas must be distinct from that of the formula: the filling of the gas is often done by an orifice located at the bottom of the container, closed by a rubber stopper.
  • This configuration requires rework during manufacture: opening of the orifice filling the gas, fitting the bag or piston, fitting the plug. It is also expensive because of the complexity of the filling process: filling of the product then of the gas.
  • this device includes a high number of pieces; these parts require very fine adjustment (no screws, tightness) and are sophisticated, therefore this device is very expensive.
  • the energy storage by mechanical compression of the cellular material is done in small quantities: the user must turn the dial to store the corresponding energy about a dose of use before pressing the push button. The need to this double action makes the device complex and unattractive to the consumer hurry.
  • the bottle in which the product is contained has the shape of a bellows, also, even if it is compressed as much as possible by the action of the foam material, this bottle cannot empty completely and you get a low refund rate.
  • the invention relates to new pressurized devices for the distribution of a product and whose characteristics appearing in claim 1.
  • the shape of the element of cellular material is defined according to the invention before its introduction into the reservoir cavity.
  • the invention is particularly well suited to a pressurized device in which the foam element and the product are subjected to pressure permanent and uniform, it applies to any type of product distributor.
  • peripheral means a slot, one end of which is situated on the periphery of the element of cellular material.
  • a peripheral slit opens the material element alveolar on the outside.
  • the devices according to the invention make it possible to distribute all kinds of products under form of solution, emulsion, gel: lotions, creams, self-foaming compositions, milks, gels.
  • Such a device makes it possible to avoid mixing of the gas with the product to be dispensed and to avoid gas leaks.
  • the duration of use of the device is extended.
  • the pressure inside the device at the viscosity of the product to be dispensed is extended.
  • this device allows to pressurize a product, without risk of product pollution by gas and without air pollution.
  • this device has only a small number of mechanical parts in common use and its manufacture is simple, so it is little expensive. Its use is simple.
  • the device is not very fragile and does not have any risks of cells bursting due to clumsy use.
  • the means of compression is retained inside the device after complete restitution of the product, this device can therefore be reused several times provided that it is recharged with product.
  • a such a device thus makes it possible to save on the cost of packaging and its possible reprocessing.
  • a device according to the invention makes it possible to obtain a rate of return of the product. around 95%.
  • a cellular material usable in the present invention consists of a multitude cells filled with gases included in a deformable matrix, such as for example a polyolefin, elastomer or any type of thermoplastic foam, a foam of rubber, Buna, Neoprene, silicone or any other material.
  • the gas can be any gas which is compressible or liquefiable at the pressures of use, like nitrogen or it can just be air.
  • the cells When the foam is compressed, the cells are also compressed, they thus store a reserve of energy to pressurize the product. When we actuates the valve of the pressurized device, the cells expand and the product is returned.
  • the gas present in the cells is retained there and cannot escape from it. We thus avoid leakage and mixing problems with the product.
  • the element of cellular material used as a means of pressurization in the devices according to the invention has a shape complementary to that of the reservoir cavity, and preferably, it is chosen in shape overall cylindrical.
  • the element of cellular material used in such a device can be manufactured so known by extrusion or by cutting from a block of cellular cellular material closed. To cut a cylinder of cellular material, you have to compress before cutting. By this process, after cutting and decompression, an element of cellular material with slightly lateral contours concaves as described in document EP-A-561292. When such an element does not having no slot at its periphery is placed in a device as described above, of the product is housed between the concavity of the element in cellular material and the walls of the container. We therefore obtain a lower refund rate than that can be obtained with a cylinder with perfectly straight contours.
  • a cylinder of foam material cut from a large block is less expensive than cylinder of extruded foam material.
  • the element of foam material used in the present invention can be extruded or even cut out. Indeed, the slot allows a wider expansion of the element of foam material, this expansion compensates for the concavity of the material elements alveolar cut. We can thus obtain an almost complete return of the product with an element of cut foam material.
  • an element of cut honeycomb material has open cells on its contours, while an extruded element does not. Therefore in the present invention it is preferred to use an element of cellular material obtained by extrusion.
  • the element of cellular material is of dimensions (height, diameter) greater than those of the reservoir cavity so that when the cavity is closed tank, we obtain a pre-compression of the element in cellular material so still have energy available when there is little product left in the device.
  • the slot is radial with respect to the cylinder of material alveolar.
  • the element of cellular material may optionally include a central orifice on all its height.
  • the slot is made over the entire height of the cylinder of cellular material and over a width substantially equal to the radius of the cylinder of cellular material.
  • the device does not include a plunger member, it may be advantageous to provide a central orifice in the element of cellular material: in fact, when mounting the device, the element made of cellular material is introduced into the reservoir cavity.
  • the element of foam material is usually greater than or equal to the height of the tank cavity.
  • the valve When the valve is placed at the top of the tank cavity, by example when crimping the valve at the top of the container body, whose walls define the reservoir cavity, using a valve holder cup, the valve exerts a mechanical compression on the top of the element of cellular material. Cells under compression burst, the cellular material element is deformed in its upper part. Product can then be lodged in this deformation. Gas is diffused in the reservoir cavity and will mix with the product.
  • a central orifice can be provided in the element of cellular material, into which the valve can be inserted even when the device does not have diving organ.
  • the slot is associated with an orifice central over the entire height of the cellular material element.
  • the slot can open the cylinder from its outer surface to its central orifice or being only superficial, that is to say, not extend to the central orifice.
  • the material element honeycomb has at most one slot extending from its outer surface to its central opening. Preferably, it has a slot extending from its surface outside to its central opening. It may have several surface slots.
  • the central orifice is preferably of elongated shape and oriented in the extension of the slot.
  • the device when the device comprises a member plunger, it is possible to provide for the cylinder of cellular material comprising a slot which extends from its outer surface to its central opening consists of a piece rectangular-shaped foam material that is wrapped around the organ diver. Indeed, the production of lumps of shaped foam material rectangular is simpler, therefore more economical, than a cylinder in which a circular central hole is cut and then a slot.
  • the device according to the invention comprises, in a known manner, a body container, the container body defining the reservoir cavity, a valve comprising a body valve separate from the container body, the valve being placed at the top of the cavity tank, a distribution means connected to the valve and a pressurization means consisting of an element in closed cell cellular material, the element in material alveolar and the product being placed in the reservoir cavity and subjected to pressure permanent and uniform, so that the device distributes the product when operates the valve

  • the device according to the invention is provided with a valve in elastomeric material comprising latching means able to cooperate with the neck of the container body as described in French patent application FR-A-2741933.
  • a second variant of the invention relates to a pressurized container comprising a cup, a valve provided with a valve body, a valve control rod possibly surmounted by a push button possibly comprising a means valve, seal and return system, cup and valve body cooperating with each other to form, on the one hand, a reservoir cavity capable of containing a product to be dispensed and a means of propulsion, on the other hand, the valve body properly said delimiting the valve cavity, a passage being arranged between the reservoir cavity and the valve cavity.
  • valve body crosses the reservoir cavity over its entire height and constitutes a plunger member.
  • the cup and the valve body cooperate sealingly with their ends to form the body of the container.
  • the cup and the body of valve include complementary fastening elements, for example means likely to snap or complementary profiles which, once assembled, are welded together by any means known to those skilled in the art, such as, for example, rotational welding or gluing.
