Definitions

  • the present invention relates to an assembly for the separate packaging of two products and for their joint distribution, with a view to producing a composition, in particular a cosmetic composition, as used for example in the field of hair dyeing. Other applications however can be envisaged.
  • each of the products to be mixed is packaged in a packaging of its own, in particular in the form of a tube or a bag.
  • the consumer pours the contents of one of the packages into the other, or the contents of the two packages in a third, within which the mixture is made.
  • the first and second products in response to pressure exerted on the flexible walls of the first and second containers, which are arranged adjacent to each other, the first and second products can be distributed together.
  • the joint output of the two products for the production of a composition can be done via a single dispensing orifice, upstream of which there may be a mixing zone in which the two products are brought into contact beforehand. to be distributed in mixed form.
  • the term "irreversible" reflects the fact that the return of the second configuration to the first is made impossible whatever the handling of the dispenser member, it being understood that, although it is not impossible to make travel to the dispensing member the reverse movement of the one that allowed the passage of the device from the first configuration to the second, this reverse movement will have no effect on the communication between the containers and the dispensing orifice, and therefore will not cause the return of the device in the first configuration.
  • the products exit via two dispensing orifices arranged next to each other, the bringing into contact of the two products being done directly on the surface to be treated in the case where the dispenser member is used as a applicator tip, or in an auxiliary container in which the mixture can be homogenized manually.
  • the choice of this or that configuration depends in particular on the viscosity of the products and their ability to mix quickly or not.
  • the single plate on which the two containers are mounted allows, by a simple movement of the dispensing member relative to the plate, in particular axial depression or rotation, to open at the same time the two containers.
  • the gesture is therefore greatly simplified.
  • the two containers especially when they are in the form of sachets, formed by the joining of two sheets welded along their peripheral edges, are arranged with a first main face of the first bag in contact (or substantially in contact) a second main face of the other bag.
  • the first and second faces may be directly opposite one another, or separated by a separation means in the form of a thin plate.
  • the plate is preferably configured so that the containers, especially when they are in the form of bags of relatively small thickness, are superimposed so that, preferably with one hand, the two bags can be compressed to cause the expulsion of their contents.
  • means in particular in the form of two plates, arranged on either side of the two superposed bags, can be used to facilitate the joint expulsion of the two products contained in each of the containers.
  • Such plates are preferably of dimensions close to those of the bags.
  • the dispensing member comprises first and second opening portions, adapted, in response to a movement, in particular axial movement, of the dispensing member relative to the plate, to come into engagement with closure elements, located well before the (or) orifice (s) of distribution, and associated with inlet / outlet passages of the first and second containers, so as to put them in fluid communication the (or) orifice (s) of distribution, said engagement being unidirectional.
  • the engagement of the opening portions with the closure elements results from a depression of the dispensing member relative to the plate. Assuming that a movement in the opposite direction is possible of the dispensing member with respect to the plate, then such a movement would have no effect on the closure elements since the engagement is only one-way.
  • the first (respectively second) opening portions consist of the free end of first (respectively second) tubular elements formed by the dispensing member and communicating with the (or) orifice (s) distribution.
  • Such tubular portions are of sufficient length to engage with said closure members, which are preferably disposed within their respective containers.
  • the free end of the first and second tubular elements is crenated so as to promote communication between the first (respectively second) containers and the (or) orifice (s) distribution when the device is in the second configuration.
  • This characteristic is advantageous especially when, as we shall see in detail later, the closure elements are coupled to binding strips whose intrinsic elasticity tends to bring them back to a position corresponding to the first configuration of the device.
  • the dispensing member may comprise locking means adapted to cooperate with corresponding means of the plate to immobilize at least axially, the dispensing member relative to the plate when the device is in the second configuration.
  • the device comprises a burglar indicator consisting of a non-repositionable element, in particular in the form of a strippable strip.
  • a burglar indicator consisting of a non-repositionable element, in particular in the form of a strippable strip.
  • the closure elements associated with the inlet / outlet passages of the first and second containers comprise a coupling means adapted to cooperate, in particular by snapping, with corresponding means of a suitable tool, before the introduction of the dispensing member, driving the first and second closure members from their position in which the first and second containers communicate with the outside, to their position in which they isolate the first and second containers from the outside.
  • these coupling means make it possible, after filling, closing said passages by said closure elements before setting up the dispenser member.
  • the tool consists of a filling rod of which at least a portion is adapted to be introduced into the inlet / outlet passages of the containers, so as to fill them.
  • the filling rod can be used during its introduction to engage with the closure elements so as to chase them in order to put the first and second containers in communication with the outside.
  • the filling rod After filling, the filling rod, during its withdrawal movement, causes the closure elements in the position where they isolate the first and second containers from the outside.
  • said first and second containers are configured in the form of bags whose walls are formed of at least one layer of a thermoplastic or metal material.
  • Such bags are generally of substantially rectangular shape. As an indication, their length may be of the order of 10 cm. Their width can be of the order of 5 cm.
  • the inlet / outlet passages of said first and second containers and their associated closure elements are formed by first and second inserts mounted, in particular by snapping, on said plate.
  • inserts are described in particular in the application WO / 9905446.
  • the closure elements associated with the inlet / outlet passages of the first and second containers are connected to their respective insert by at least two flexible connecting strips.
  • These binding strips are advantageous during filling where it is desirable to be able, before filling, to remove the closure elements and then to be able to return them to position after filling.
  • the first and second containers may be mounted on the first, respectively second, inserts, especially by gluing or welding.
  • the first product may be a dye
  • the second product may be an oxidant
  • said composition to be produced at the end of the mixture being a hair dye composition.
