Patent ID: 8235618

Claim:
A device for distribution of a dose-sample for testing a cosmetic composition that is to be applied, such as, typically, mascara, lipstick or nail polish, which comprises: a reservoir ( 9 ; 9 a to 9 h ) that is delimited by a zone ( 4 a ) for interlocking two units (E 1 and E 2 ) and that comprises a distribution hole ( 18 ) for distribution of the cosmetic composition, at least one (E 1 ) of the units (E 1 and E 2 ) is a shell ( 1 ; 1 a to 1 d ) that comprises a cavity ( 3 ) that has a transverse collar ( 4 ) that is part of a interlocking zone ( 4 a ), and at least one of the units (E 1 , E 2 ) has a transverse collar ( 4 ) that comprises a trough ( 5 ), an applicator ( 17 ) that comprises a gripping element ( 11 ; 11 a to 11 h ), provided with a rod ( 14 ) that passes through the distribution hole ( 18 ), the rod having a first end ( 14 b ) and second end ( 14 a ), the first end ( 14 b ) equipped with a nozzle ( 16 ) for the distribution of the cosmetic composition that is located in the reservoir ( 9 ; 9 a to 9 h ), wherein, the distribution hole ( 18 ) is in fluid communication with the reservoir ( 9 ; 9 a to 9 h ) via a spout ( 10 ) that is formed by the space that is left between the two units (E 1 and E 2 ) after interlocking, whereby the trough ( 5 ) at least partially forms a wall of the spout ( 10 ), wherein the spout ( 10 ) has a narrow and relatively circular structure so as to form a blotting element of the applicator ( 17 ), an element ( 11 ) for sealing the distribution hole ( 18 ) obtained by interlocked portions ( 7 c , 7 d ) of an expansion ( 7 ) of the transverse collar ( 4 ) between which is included the second end ( 14 a ) of the rod ( 14 ), and a divisible structure provided to open the distribution hole ( 18 ), wherein, the rod ( 14 ) is held by the interlocked portions ( 7 c , 7 d ) of the expansion ( 7 ), a second end ( 14 a ) of the rod being kept in and connected to the interlocked portions ( 7 c , 7 d ) so that the sealing element ( 11 ) constitutes the gripping element of the applicator ( 17 ) to prevent any contamination of the gripping element with the cosmetic composition and any tilting or rotation of the rod ( 14 ) while the device is being opened and while the applicator ( 17 ) is being used, and the interlocking zone ( 4 a ) surrounds the trough ( 5 ) and is reduced at an interlocking zone ( 8 ) with a scoring line ( 8 a ) located between the expansion ( 7 ) and the traverse collar ( 4 ), forming the divisible structure, such that the breaking of the interlocking zone ( 8 ), by torsion, opens the distribution hole ( 18 ).
