A jar for cosmetic products that includes a base surmounted by a neck and a lid, the neck having a non-circular cross-section and including a rim. The neck includes at least one first assembly element, the lid including at least one second assembly element. The lid is configured so that: (1) when the lid is in a closed position: (1a) the at least one second assembly element is arranged under the rim; and (1b) the at least one second assembly element and the at least one first assembly element are nested together, and (2) when the lid is in an open position, the at least one second assembly element is disengaged from the at least one first assembly element and the rim The lid is configured to pass from one position to the other by rotation about the neck.

A receptacle includes a container and a cap, the cap being attachable to the container for closure of the receptacle, and having a passage with an opening. The container has a neck for the passage along a longitudinal axis of the receptacle, and the opening has a non-circular shaped inner contour formed complementary to a non-circular shaped outer contour of the neck. An inner circumferential surface of the passage and an outer circumferential surface of the neck are formed so that a form-fitting engagement is generable by rotating the cap relative to the container around the longitudinal axis, and the inner circumferential surface of the passage and the outer circumferential surface of the neck are formed so that a press-fining engagement in a radial direction is generable by rotating the cap relative to the container around the longitudinal axis after the cap is in form-fining engagement with the neck.
