Definitions

• the present invention relates to an applicator for applying a cosmetic, makeup or care product to the eyelashes and/or eyebrows, for example mascara.
• the invention also relates to devices comprising the applicator and to a container containing the product to be applied.
• the container is conventionally provided with a wiping member which wipes the stem of the applicator as it is withdrawn from the container.
• a wiping member which wipes the stem of the applicator as it is withdrawn from the container.
• the behaviour of the application member on passing through the wiping member depends on numerous factors, such as the shape and nature of the lip of the wiping member and the arrangement of the application elements on the application member.
• EP 1 070 465 and EP 1 070 466 disclose combs having a row of teeth disposed in staggered rows, which are partially or entirely superposed.
• EP 2 084 987 discloses a brush comprising rows of spikes disposed between rows of teeth of flattened cross section, the spikes alternating longitudinally with the teeth.
