Definitions

  • the present invention relates to the field of rechargeable packaging devices for cosmetic products.
  • Cosmetic product is understood to mean in particular all the products for making up the skin, including the lips, and all the compositions intended for a body application, including so-called care products such as moisturizers. It relates in particular to the field of refills for refillable cosmetic product packaging devices.
  • a packaging device for a cosmetic product generally designates any container used to contain a cosmetic product with a view to its conservation, transport, marketing or use.
  • the jars, flasks, cases, etc. are designated. used to contain a cosmetic product.

  • the refill Once in place in the shell, the refill must be properly held in the shell. In particular, care should be taken to prevent the refill from escaping from the shell, during its transport or its use during which the pot can take any orientation, in particular a complete overturning of the packaging device, that this results from 'a voluntary action or not. In addition, the refill must not move in the shell when using the conditioning device. The refill must remain fixed when dispensing the product, for example when the user takes product from the refill.
  • the refill must be able to be easily extracted from the shell, with a view to its replacement.
  • Known refillable packaging devices generally include systems for maintaining the refill in the shell which are visible and unsightly, and / or which require industrially complex or costly adaptations.
  • the document JP2013119399 thus discloses a cosmetic product jar comprising a refill, the tank of which is generally cylindrical in shape of revolution and comprises reliefs which slide, by correspondence of shape, in vertical grooves formed in the shell of the jar to prevent the tank from rotating.

  • WO2019058087 also discloses a refill jar device of similar configuration, comprising an inner vessel or container which matingly engages an outer shell container, the shell having a peripheral bead which cooperates with a groove formed on the outer surface of the shell. tank.
  • the upper part of the shell has a neck comprising slits in which radial beads of the tank are introduced to allow the latter to be kept in rotation.
  • the refill packaging devices known in the state of the art are based on a correspondence of shape between the shell and the refill, which allows for example by clipping (or other relative mechanical engagement) the maintenance of the refill in the shell.
  • This requires a particular conformation of the shell and of the refill, which prevents, for example, being able to use a shell of conventional shape, such as a standard glass container, to form a refillable packaging device, and, similarly, prevents it from being used.
  • use a refill in the form of a tank of conventional shape for example a glass or stainless steel tank of conventional shape.

  • the elastomeric material element can be overmolded on the shell.
  • the shell may be formed of a plastic material.
  • the shell and the elastomeric material element that it presents can be formed together by two-material injection.
  • the shell can thus be produced by known and controlled industrial processes, which provide good cohesion between the shell and the element made of elastomeric material which it carries.

  • the elastomeric material used and its hardness allow it to be deformed under a reasonable force, compatible with the application to a cosmetic product refill.
  • the elastomeric element may extend along one or more bands parallel to the opening of the shell.
  • the element made of elastomeric material can form discrete studs distributed over the surface of the inner wall of the shell.
  • the element made of elastomeric material can form at least two studs and preferably at least three studs distributed over a periphery of the surface of the inner wall of the shell.
  • the receiving volume may be of generally cylindrical shape of revolution, or frustoconical, or straight prismatic.

  • the elastomeric material element can be deformed in said support zones by compression on the side wall of the refill, compared to a configuration that the elastomeric material element adopts in the absence of external stresses.
  • the deformation of the element made of elastomeric material on the bearing zones increases the force which it exerts on the interior surface of the shell, and thus increases the friction which opposes the extraction of the refill.
  • the side wall of the refill is devoid of any roughness such as grooves, orifices, pins or snap rings.

  • the open face can be free, directly exposing the product contained in the tank 2 of the refill, or be provided with a regulating device such as a sieve, a net, or other device adapted to the product to be dispensed.
  • the refill thus has a simple, classic form.
  • the refill and in particular its side wall 3 and more particularly the outer surface 7 of this side wall 3, is devoid of any roughness or other snap-fastening means.

  • the side wall surface 3 in particular has no groove, no orifice, no pin or no snap ring.
  • the refill can thus be easily produced, or can consist of a standard container, for example a plastic, glass, or stainless steel jar.
