Definitions

  • the present invention relates to the field of refillable packaging devices for cosmetic products.
  • cosmetic product is understood to mean in particular all products for making up the skin, including the lips, and all compositions intended for bodily application, including so-called care products such as moisturizing creams. It relates in particular to the field of refills for rechargeable devices for packaging cosmetic products.
  • 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. Pots, bottles, cases, etc. are thus designated, for example. used to contain a cosmetic product.
  • refill is meant a removable element comprising a tank adapted to contain a cosmetic product, and which can be put in place and removed from a shell which forms the external surface of the refillable cosmetic product packaging device consisting of a shell and a recharge.
  • the refill Once in place in the hull, the refill must be correctly maintained in the hull. 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 reversal of the packaging device, whether 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 during the dispensing of 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 rechargeable packaging devices generally comprise 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 pot of cosmetic product comprising a refill, the tank of which is of generally cylindrical shape of revolution and comprises reliefs which slide, by correspondence of shape, in vertical grooves provided in the shell of the pot to prevent the tank from rotating.
  • the document EP0661012 also discloses a refill pot device, comprising an inner tank or receptacle which engages by form correspondence in an outer receptacle forming a shell, the inner receptacle being able in particular to comprise a peripheral bead which cooperates with a groove formed inside from the neck of the outer container.
  • WO2019058087 also discloses a refill pot device of close configuration, comprising an inner tub or receptacle which form-fits into an outer receptacle forming a shell, the shell having a peripheral bead which cooperates with a groove formed on the outer surface of tank.
  • the upper part of the shell has a neck comprising slots into which radial beads of the tank are inserted to allow the latter to be held 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 (that is to say snap-fastening or other relative mechanical engagement ) maintaining the refill in the hull.
  • 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 use a refill in the form of a tank of conventional shape, for example a glass or stainless steel tank of conventional shape.
  • the invention aims to solve all or part of the aforementioned problems.
  • the invention relates to a shell for a refillable device for packaging a cosmetic product which is adapted to receive a refill adapted to contain the cosmetic product.
  • the shell has an opening forming a neck, this opening being adapted to receive the refill in order to place it in a receiving volume defined by an interior wall of the shell.
  • the shell further comprises a ring connected to the neck, said ring extending over at least a portion of the inner wall of the shell forming said neck.
  • the ring has an inner surface at which is linked an element of elastomeric material which is at least partly in relief vis-à-vis said inner surface of the ring.
  • the shell thus formed is capable of maintaining a refill of suitable shape, thanks to the element made of elastomeric material.
  • the support obtained, nevertheless allowing the extraction of the refill, uses the elastic properties and the coefficient of friction of the elastomeric material.
  • the implementation of the recharge is thus very simple.
  • the element made of elastomeric material being carried on an attached ring and connected to the shell, the invention can be implemented on shells of very varied constitutions and shapes.
  • the element made of elastomeric material can be molded onto the ring.
  • the ring can be formed from a plastic material.
  • the ring and the element of elastomeric material that it presents can be formed together by bi-material injection.
  • the ring can thus be produced by known and controlled industrial processes, which provide good cohesion between the ring and the element made of elastomeric material that it carries.
  • the elastomeric material used can be an elastomeric thermoplastic or an elastomeric silicone. It may have a hardness of between 20 degrees shore and 80 degrees shore, and preferably between 40 degrees shore and 60 degrees shore. The elastomeric material used and its hardness allow it to deform under reasonable effort, compatible with application at a cosmetic product refill.
  • 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 surface of the ring in its part situated on the surface of the inner wall of the neck of the shell.
  • the element made of elastomeric material can extend along one or more strips parallel to the opening of the shell.
  • the reception volume can be of generally cylindrical shape of revolution, or frustoconical, or straight prismatic.
  • the shell may consist mainly of plastic material, glass, stainless steel, aluminum, or wood.
  • the shell can be formed from one of the aforementioned materials, with the exception of the ring and the element made of elastomeric material.
  • the shell has an aesthetic aspect which can be essential in the field of cosmetic products.
  • the ring can be linked to the neck of the shell by clipping and/or by gluing. Any other known rigid and reliable connection mode can be used.
  • this bonding be done between the ring and the external wall of the shell, and/or between the ring and the internal wall of the shell, and/or on the periphery of the neck of the hull.
  • the invention also relates to a packaging device for a cosmetic product comprising a shell as defined above, a refill in which the refill comprises a side wall having a clearance vis-à-vis the inner wall of the shell, except at the level of all or part of the element made of elastomeric material, so that support zones for the element made of elastomeric material are formed on said side wall of the refill.
  • the means allowing this maintenance can be invisible (if the shell is opaque) or at the very least very discreet, so that they do not harm the aesthetics of the pot that is made up.
  • the element made of elastomeric material can be deformed in said bearing zones by compression on the side wall of the refill, compared to a configuration that the element made of elastomeric material adopts in the absence of external stresses.
  • the deformation of the element made of elastomeric material on the support zones increases the force which it exerts on the inner 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 asperities such as grooves, orifices, pins or snap rings, at least in a zone of interaction of said side wall with the element made of elastomeric material .
  • the side wall of the refill is devoid of roughness below an element of the tank intended to come into vertical support on the shell (edge, peripheral bead, etc.).
  • the maintenance of the refill does not does not require forming on it any particular shape intended to cooperate with means for holding the shell.
  • the refill tank of which is filled with a cosmetic product the shell and the refill can be configured so that a force necessary for extracting the refill is greater or equal to twice, and preferably greater than or equal to two and a half times the weight of the refill.
  • the shape, the dimensions and the constitution of the element made of elastomeric material are configured so as to obtain the force necessary for the extraction of the desired refill.
  • This holding force allows relatively easy removal of the refill for its replacement. It corresponds to a desirable specification for pots of conventional cosmetic products.
  • the tank may comprise a lid connected by snap-fastening or screwing to the rest of said tank. This allows nomadic use of the tank alone, without the shell, to transport the cosmetic product it contains.

  • Such a rim can also form a support zone for the tank when it is inserted into a corresponding shell.
  • the tank 2 has a thread 15 allowing the adaptation of a screw cap on the tank. The tank 2 can thus be used on its own, independently of the shell described below in section figure 2 , in order to transport the cosmetic product it contains.
