Definitions

  • the present disclosure generally relates to a cosmetic package including an adjustable applicator for applying a product such as for example mascara, eye shadow, lip-gloss, nail polish, eye liner etc. More particularly, the present disclosure generally relates to a mechanism for preventing undesirable actuation of the actuator of the cosmetic package.
  • cosmetic packages include applicators having a stem, at one end of which is connected an application member and at the other end is provided a cap intended for closing a receptacle.
  • the application member is adapted to apply the product and may be a brush for e.g. a mascara brush or a lip or a face applicator made from sponge, plastic etc.
  • the conventional cosmetic packages further comprise a wiper through which the stem and application member passes on being withdrawn from the receptacle. The wiper is supported by a neck of the receptacle. The wiper serves firstly to wipe the stem and secondly to remove excess cosmetic from the application member.
  • adjustments to the brush section can be made by adjusting the dialer of the cap, more specifically they include a rotatable cap.
  • none of the prior art patents provides means for protecting the dialer against accidental actuation or unintentional actuation by the user in the closed position of the cosmetic package.
  • the actuation of the dialer/rotation of the cap in the closed position of the cosmetic package is undesirable as the accidental actuation causes the application member to deform in the storage position.
  • the deformation of the application member such as increase in diameter thereof or curving thereof may be undesirable because during withdrawal from the receptacle it may cause damage to the application member.
  • Normally wipers employed in such cosmetic packages are designed to function effectively on non-deformed application member and therefore withdrawing of the deformed application member will not provide proper wiping to the application member and hence proper make up effect may not be achieved.
