Definitions

  • the invention relates to a new pressurized container, having, with a reduced number of parts, two valves: a first valve for the distribution of product, and a second valve for filling the container, refilling this when its content has been exhausted, or adding an additional asset to the product initially contained in the container.
  • the invention is particularly suitable for the distribution of cosmetic or dermo-cosmetic products, under liquid, foam, gel, or cream form.
  • such a small device can be used advantageously for a precise dosage of product for each use, especially in the field of pharmacy and dermo-cosmetics.
  • a concept has still not seen the light of day, mainly for cost reasons.
  • a pressurized container even a small one, requires, in order to function, a certain number of essential elements, which are the container body, i.e. a tin or aluminum can, on the walls of which a varnish is deposited and on the neck of which is crimped a valve, via a valve holder cup, as well as a distribution means connected to the valve.
  • the technique of manufacturing pressurized cans does not allow manufacturing cans small enough to match the volume of a test dose, or 3.5 ml to 8 ml approximately.
  • the work of crimping metal crimping the valve holder cup, on the container body, on the one hand, and around the valve, on the other hand
  • This manufacturing constraint therefore conditions the size of the valve holder cup and therefore the volume of the container, which is necessarily greater than a dose of use.
  • rechargeable devices always consist of a container, a first valve for the distribution of the product, a system of filling, which is in fact, no more and no less than a second valve.
  • German patent DE 1,166,225 describing such a container fitted with two valves, each valve comprising a valve body and a separate spring, for, in the absence of an actuation command, maintain the valves in the closed position.
  • Patent FR 1 228 733 describes a refillable aerosol can, in which the filling or recharging, is carried out by means of an auxiliary container, by the same valve as that used for dispensing the product.
  • patent FR 2 378 572 describes a process making it possible to aspirate and store a predetermined dose of a product, inside a removable head.
  • the two operations occur simultaneously by the compression of a spring during the screwing of the head on a tank, and the compression of the dose stored at adequate pressure by loosening the head and releasing the same spring, so that, after the separation of the head and the tank, the head, made independent, can be used as an aerosol can.
  • Spraying takes place by opening a separate valve held in the closed position by a separate spring.
  • Another problem is to offer the consumer products cosmetics, for example, products combining two active ingredients in one only formula.
  • products two in one "available on the market, such as treating shampoos, styling-nourishing, make-up removers and moisturizers, etc.
  • Such packaging is not possible as long as the two assets are compatible with each other and compatible with the support.
  • Some formulas are impossible to formulate in the current state of the art, because the two active agents are incompatible with each other.
  • the difficulty with such products is that since the assets are not stable when mixed, they should be used quickly after mixing and by therefore, must be either single-dose or of sufficiently small volume to be used in a shorter period of time than the time during which the mixture is active enough to be used with good efficacy.
  • Patent applications EP-A-063 759 and EP-A-217 582 describe systems for the extemporaneous mixing of two products by means of devices pressurized, mixing takes place in a device with two valves: a valve intake and distribution valve. Each of the valves has a cup, valve body, valve stem, seal and spring. Such a design has the disadvantage of being of a high cost price, due to the number of parts used. Furthermore, it does not authorize manufacturing single-dose, or multi-dose devices of low volume. A similar system is described in patent FR 1 431 181.
  • a device comprising a pressurized product tank, on which a first valve is mounted and a second valve, said second valve being oriented opposite the first valve, and substantially in alignment with the first valve, means for distribution being associated with at least one of said first or second valves, each of the valves comprising means for, in response to a command, selectively allow the opening / closing of said valves, means of elastic reminder for, in the absence of an order, to request resources opening / closing in closed position, characterized in that said first and second valves are mounted inside the same body in communication with the reservoir, and are biased in the closed position by the same means of elastic recall.
  • a device with two actuated valves is produced independent, and this, with a limited number of pieces.
  • the means for opening / closing the first and / or the second valve may consist of an emerging valve stem, of the side-tilt type, or depressing.
  • a lateral tilting rod being a rod mounted so as to ability to tilt out of its axis, so as to connect a passage or orifice in the vicinity of its lower end, with the body valve on which it is mounted, thus allowing the product under pressure, contained in the valve body, to go back up inside the valve stem view of its distribution.
  • a push-in valve stem setting communication of the passage or orifice, is ensured by pushing in the rod in the valve body, along the axis of the stem.
  • the means for opening / closing the first and / or the second valve consist of a female member capable of receiving so removable, a control rod.
  • This control rod can be part part of an actuation and distribution device, button type pusher, or consist of the valve stem emerging from an auxiliary container used to recharge the device. This characteristic, especially for the valve intended for refilling the container, is a possible solution to the problem accidental actuation of the filling valve.
  • the device may include a push button mounted on the first valve, in view of valve actuation and product distribution, the second valve being intended for filling or refilling the tank.
  • the push button includes a diffusion means, of the grid, porous dome, or nozzle.
  • the device comprises a body and a bottom, the body forming a valve holder cup for the first valve, the bottom forming a valve cup for the second valve, the body of the device cooperating with the bottom to form, on the one hand, the reservoir of pressurized product, and on the other hand the valve body for said first and second valves.
  • This configuration is particularly advantageous in that it helps to limit even more importantly the size of the device and the number of parts put used in such a device, thereby also reducing its cost of manufacturing. Furthermore, the mounting of such a device is very simple.
  • the first valve may include a first valve stem including a first end opens into the valve body, a second end opening out of the valve body, the second valve comprising a second valve stem, a first end of which opens inside the body valve, substantially opposite the first end of the first rod valve, a second end opening to the outside of the valve body, the elastic return means consisting of a spring bearing between said first ends of said first and second valve stems.
  • the first end of the second valve stem advantageously has a substantially flat portion, one face of which is situated opposite the bottom of the valve body, the second valve being held in the closed position by a support elastic between a sealing ring formed on said face and a seal crossed by the second valve stem and disposed in the bottom of the valve body, said seal being in tight contact, on the one hand with the internal walls from the second central chimney, and on the other hand with the second valve stem.
  • the body of the device can be tightly mounted on the bottom by welding, snap-fastening, screwing or gluing.
  • the body may consist of a transverse wall, forming a valve holder cup for the first valve, a first side skirt defining an external contour for the tank, and a first central chimney of given internal diameter, and defining an internal contour for the reservoir, the bottom having a wall transverse, forming valve holder cup for the second valve, a second side skirt cooperating with the first for attaching the bottom to the body, and a second central chimney forming a valve body, said second chimney central with an external diameter, slightly smaller than the internal diameter of the first central chimney, means being provided to allow the communication between the tank and the valve body.

  • the means allowing communication between the reservoir and the valve body are arranged to allow either upside down operation or head at the top of the device, whatever the position of the device.
  • the choice of this or that configuration depends on the application of the device and its Terms of use.
  • the bottom has a step in which the second valve stem emerges, said recess having a height according to the axis of the device greater than the height of the emerging part of the second valve stem.
  • such an offset is used in a way advantageous, in the case of a female type opening / closing member, for stacking several such devices.
  • Such a drop can present on its lateral walls external to the device, a profile forming a key, said profile having a profile complementary to that of an adapter intended for be mounted on an auxiliary container for recharging the device.
  • This characteristic makes it possible to prevent, or in any case, to limit so the risks of filling the container with a product other than that recommended by the device manufacturer, which could constitute a danger to the person performing such filling. This also allows limit the risk of seeing a container, initially marketed for a product of a given trademark, recharged later by a product competitor.
  • the bottom can be between the second side skirt and the second chimney central, a rounded annular profile, the concavity of which faces inwards of the tank. This characteristic contributes to substantially improve the degree of emptying of the tank.
