  • Patent number: 10966504
    Abstract: This pot comprises a shell (9) comprising a bottom (15) so that the pot (1) can be placed on a surface (3), and a side part (17), and an insert (11) designed to contain the cosmetic product (2). The insert (11) is designed to be inserted into the shell (9) and fixed on it in an assembled position of the pot (1), in which the insert (11) and the shell (19) define an interstitial space (43) extending in front of the bottom (15) and the side part (17). The pot (1) also comprises a mechanical tensioning element (13) of the shell (9) that can be in a compressed position between the shell (9) and the insert (11) when the shell (9) and the insert (11) are in the assembled position.

  • Patent number: 8579531
    Abstract: This device comprises a container (12), a head (14) which is for dispensing cosmetic product and which is provided with a rotary application member (44) and a retention cap (42). It comprises a blocking cover (16) which can be moved between a position for blocking the container (12) and a position for dispensing the product. The container (12) is shaped so as to prevent the device (10) from being retained in a stable manner on a horizontal support with the head (14) in an upward position. The cover (16) comprises a member (86) for urging the rotary application member (40) against a sealing seat (60) delimited by the cap (42) in the blocking position of the cover. The urging member (86) can be resiliently deformed relative to the cover (16) between an idle configuration and a resiliently deformed configuration.

  • Patent number: 7819125
    Abstract: A case for packaging a product may include a first portion defining a housing and an opening permitting access to the housing. The opening may face in a first direction. The case may include a second portion pivotally coupled to the first portion via a pivot member so as to permit pivoting of the second portion with respect to the first portion about a pivot axis substantially parallel to said first direction. The second portion may be pivotally movable with respect to the first portion between a closed position covering the opening and an open position.
