Definitions

  • TITLE Refillable assembly for packaging a cosmetic product comprising a device forming a refill and a device for axial retention of said device forming a refill in a cover assembly
  • the present invention relates to the field of refillable assemblies for packaging a product, in particular a cosmetic product.
  • a “cosmetic product” is understood, in particular within the meaning of the present invention, to be a product as defined in Regulation (EC) No 1223/2009 of the European Parliament and of the Council of 30 November 2009 on cosmetic products.
  • the invention relates to a refillable assembly for packaging a product comprising a container containing a product and a cover assembly for said container, in which the container is mounted.
  • the container forms a refill adapted to be replaced when the product it contains is used up.
  • the aim is to propose reusable eco-responsible containers, in particular containers that can be refilled in the home or in a shop, in order to reduce the carbon footprint of the packaging.
  • the present invention forms part of this strategy of developing refillable packaging for the field of cosmetic products, and in particular care or make-up products, notably for keratin fibres, in particular the eyelashes and/or eyebrows, such as a mascara, a product for making up the lips, such as a lipstick or a gloss, or a product for making up the skin, such as a concealer, applied to localized areas of the face.
  • the containers forming the refills take the form of minimalist assemblies, adapted to be combined with cover elements so as to form a ready-to-use packaging assembly offering the user optimal performance, in particular in terms of aesthetics and ease of use.
  • Document JP-B2-3638756 discloses a container forming a refill mounted in a cover element and held axially in said cover element by a ring that rotates as one with the cover element.
  • Said ring comprises two protruding portions extending radially inwards and each intended to be placed selectively facing a shoulder provided on the container forming a refill in an axial holding position and thus prevent it from being axially removed from the cover element and facing a flat area provided on the shoulder of the container so as to allow it to be removed axially from the cover element.
  • Document CN217285031 also discloses a ring for axially holding a container forming a refill in a cover element, comprising a push button intended to interact with a notch provided on the container forming a refill in an axial holding position.
  • a push button intended to interact with a notch provided on the container forming a refill in an axial holding position.
  • the user presses radially on the push button so as to elastically deform the axial holding ring and disengage said push button from the notch on the container forming a refill.
  • the present invention therefore aims to overcome the above disadvantages and improve refillable assemblies for packaging a product comprising a container forming a refill and a cover element, the aim being to enhance the axial retention of said container forming a refill relative to the cover element in a position of use of the product and to facilitate the removal of the container forming a refill from the cover element in the event of replacement of said container forming a refill.
  • Another aim of the invention is to enhance the perception of quality by the user and prevent any accidental removal of the container forming a refill.
  • the invention relates to a refillable assembly for packaging a product, notably a cosmetic product, extending axially along a longitudinal axis and comprising at least:
  • a device forming a refill comprising a container or vial delimiting an internal volume intended to receive the product
  • a cover assembly delimiting an internal space for receiving the device forming a refill.
  • the refillable packaging assembly comprises a device for axial retention of the container relative to the cover assembly comprising:
  • the flexible tab is elastically deformable in the radial direction between an initial position in which said flexible tab extends axially along a first axis substantially parallel to the longitudinal axis and a deformed position in which said flexible tab extends along a second axis forming an angle with the longitudinal axis.
  • “Flexible” or “elastically deformable” means any member capable of deforming under the action of a stress exerted, for example the passage of the snapfitting elements as a result of a removal force applied on the device forming a refill and tending to remove same from the cover assembly, and of returning to its initial shape after cessation of said stress.
  • the axial retention device makes it possible to ensure axial retention of the container of the device forming a refill relative to the cover assembly.
  • a “product” is understood to be a fluid or semi-fluid product, for example a care or make-up product, in particular for making up the lips, or a product for caring for or making up the epidermis of a user.
  • the axial retention system formed by the flexible tab and the snap-fitting element is adapted to ensure the retention of the device forming a refill relative to the cover assembly without requiring any relative movement between these elements other than a translational movement along the longitudinal axis, and in particular without requiring any relative movement of rotation of these elements about the longitudinal axis.
  • such an axial retention system allows the retention of the device forming a refill relative to the cover assembly regardless of the relative angular position of these elements about the longitudinal axis.
  • the user does not need to place the device forming a refill in a particular angular position relative to the cover assembly about the longitudinal axis, and then turn these elements relative to one another about the longitudinal axis, which makes it possible to improve the ergonomics and the ease of use of the refillable assembly.
  • the device for axial retention of the container relative to the cover assembly comprises at least two flexible tabs distributed circumferentially, for example regularly or irregularly, around the cover assembly.
