Housing base and associated housing and assembly method

A housing base for containing a cosmetic product, comprising:

• a compartment fitted into a support and comprising a bottom and at least one lateral wall;
• a part for containing the cosmetic product and embedded in the compartment, the part comprising a bottom positioned on and parallel to the bottom of the compartment and at least one lateral wall positioned parallel to the lateral wall of the compartment;
• a first locking means for locking the part embedded in the compartment by preventing relative movements of the part and the compartment along a first axis (Z) perpendicular to the bottoms of the part and compartment, and wherein the first locking means comprises a first hollow element fitted with a second protruding element of a shape complementary to the first element, one of the first or second elements being fitted into the lateral wall of the compartment and the other being fitted into the lateral wall of the part;
• and
• a second locking means for locking the part embedded in the compartment by preventing relative movements of the part and the compartment along a second axis (Y) perpendicular to the lateral wall and preventing a rotation of the part with respect to the compartment around a third axis (X) perpendicular to first and second axes, and wherein the second locking means comprises a third hollow element fitted with a fourth protruding element of a shape complementary to the third element, one of the third or fourth elements being fitted into the bottom of the compartment and the other being fitted into the bottom (310) of the part (30).

A method for assembling a housing base for containing a cosmetic product,

• wherein the base comprises at least one compartment fitted into a support and a part for containing the cosmetic product and suitable for being embedded into the compartment;
• wherein the compartment comprises at least one lateral wall with one element from among a first hollow element and a second protruding element of complementary shapes and a bottom with one element from among a third hollow element and a fourth protruding element of complementary shapes;
• wherein the part comprises at one lateral wall with the other element from among the first hollow element and the second protruding element and a bottom with the other element from among the third hollow element and the fourth protruding element;
• and the method comprising the steps of:
• positioning a part of the housing base directly above the compartment;
• positioning the bottom of the part parallel to the bottom of the compartment;
• applying a pressure perpendicular to the bottom of the part and the bottom of the compartment to embed the part into the compartment;
• and
• sliding the lateral wall of the along the lateral wall of the compartment until the first and second elements connect together and until the third and fourth elements connect together to lock the part embedded in the compartment.
