Definitions

  • the invention relates to the field of dispensers for fluid cosmetic products that include a receptacle forming a vessel for the cosmetic product and that is equipped with a neck sealed by an applicator forming a cap that can be screwed onto the neck; at one end, the cap is integrated into a rod that, at its other end, bears means for applying the cosmetic product.
  • the neck of this type of dispenser generally includes an insert that forms a wiping element or “wiper” that is intended to limit the quantity of cosmetic product withdrawn from the receptacle each time the applicator is withdrawn from the dispenser in order to apply the cosmetic product onto the human body, face, nails, or eyelashes, depending upon the nature of the cosmetic product.
  • a wiping element or “wiper” that is intended to limit the quantity of cosmetic product withdrawn from the receptacle each time the applicator is withdrawn from the dispenser in order to apply the cosmetic product onto the human body, face, nails, or eyelashes, depending upon the nature of the cosmetic product.
  • the wiper is a basic element of the dispenser and its essential functions are absolutely critical to ensuring proper operation of the dispenser and a good service life of the product contained inside the body of the dispenser forming the vessel.
  • the wiper may form a seal for the dispenser in order to prevent any cosmetic product leakage or loss, and to prevent any drying of the cosmetic product due to evaporation of its liquid and volatile components.
  • the wiper's primary role is to regulate the quantity of product remaining on the applicator after the latter has been extracted: dispensing of the appropriate quantity is determined by the diameter of the wiper opening. It is important for the applicator to carry only a predetermined quantity of cosmetic product in order to obtain the desired effect, typically a makeup-type effect.
  • the wiper is usually joined to the neck of the receptacle or of the bottle.
  • the material making up the wiper must be able to deform when the dispenser is closed, with one part of the wiper forming a seal that can be compressed between the neck and the cap, both of which are rigid parts.
  • Wipers are made of thermoplastic polymers, polyolefins (PE, LDPE), or elastomers, such as Buna rubber.
  • PE polyolefins
  • elastomers such as Buna rubber.
  • the use of wipers made of elastomer is limited by the higher cost of elastomers in comparison to polyolefins and by problems encountered during assembly on automatic lines due to their high flexibility.
  • dispensers typically mascara dispensers, including a wiper that can also act as a seal for the vessel, are known.
  • the wiper is usually integrated into the neck by snap fitting; that is, by cooperation of parts in relief with hollow elements.
  • the elastic memory of a material is the ability of a material subjected to permanent deformation to cause stress that in turn lasts over time. If the material of the wiper were to have high elastic memory, it would remain permanently under stress due to permanent deformation and therefore would remain integral to the neck.
  • thermoplastic materials undergo gradual elastic memory loss, such that wipers made of thermoplastic material are subject to the inherent risk of coming apart from the neck.
  • certain new formulations of cosmetic products may contain chemicals that tend to act upon the material making up the wiper; in particular, they tend to soften it, which may greatly contribute to rapid elastic memory loss. Additionally, other chemicals may acts as lubricants, which may facilitate separation of the wiper from the neck.
  • the invention targets a solution to the problem of permanently attaching the wiper to the neck of the dispenser body; the solution must be both inexpensive and compatible with requirements in cosmetic products dispensing.
  • the cosmetic product dispenser includes a receptacle for containing the cosmetic product that is equipped with a neck, typically threaded on the outside, and an applicator that typically includes a cap, usually threaded on the inside, that cooperates with the neck to seal it and to ensure that the applicator can be manually gripped, an axial rod that is integral to the cap at its upper end and, at its lower end, an application material that is able to take up a small amount of the product;
  • the neck has a wiper that is integral to the neck and that enables wiping of the application material each time the applicator is withdrawn from the receptacle in order to apply the product to a support;
  • the wiper includes a body that forms an inner skirt coaxial to the neck and typically an upper flange that rests against a lip or upper surface of the neck, and a lip inside the body that wipes the application material, wherein the wiper, typically via the skirt or the upper flange, cooperates with the neck by a weld area such that the
  • the means characterizing the present invention resolves the presented problem. Indeed, with this means, the wiper and the neck, even though they may be composed of different materials, form a solid single piece, since the weld area is extensive enough to withstand axial stress higher than 1 daN, even 2 daN, whereas the axial stress, even when a deposit has formed under the wiper, may typically be around 0.3 daN at the most.
  • This means is a permanent means that makes it possible to disregard completely the wiper's elastic memory, since there is no longer any permanent or presumed-permanent deformation or stress.
  • the wiper can cooperate with the neck without becoming deformed, this facilitates the placement and fitting together of the wiper and neck on the production line, such that the invention can be produced at high speed.
  • FIG. 1 a shows a dispenser ( 1 , 1 ′) for mascara ( 7 , 7 ′).
