Definitions

• the present invention relates to a rotating case of the type used to contain cosmetic products, such as lipsticks or lip creams.
• Such rotary cases schematically comprise a base mounted movable in axial rotation relative to a tubular body inside which is movably mounted in displacement a slider intended to receive a product to be protected.
• revolving cases are generally made of plastic because it is an inexpensive material, which is more easy to work in particular by molding.
• plastic has the disadvantage of giving the rotating case a very light weight which is absolutely not synonymous with quality in the world of luxury.
• too great a lightness is also not able to provide comfort in the hand that is satisfactory for the user.
• a rotating case that is too light does not allow optimal control of movements during use, hence a notable lack of precision.
• the technical problem to be solved, by the object of the present invention is to propose a rotary case comprising a base mounted movable in axial rotation relative to a tubular body inside which is movably mounted in displacement a slider intended to receive a product to be protected, a rotating case which would avoid the problems of the state of the art by offering real perceived quality, while guaranteeing significantly improved comfort and precision of use.

• the heights in question are identical because it is an optimized embodiment. But it is obvious that the important thing is that the respective dimensions of the cursor (4) and the guide means (20) are not greater than those of the base (2).
• the outer wall of the base (2) must indeed hide both the cursor (4) and the guide means (20) when the rotary case (1) is in the retracted position, that is to say when the cursor is in the low position.
• Figures 5, 6 and 7 specifically illustrate the base (2) which has a shape substantially complementary to the lower part

• the centering means (40) comprise four centering projections (43a, 43b, 43c, 43d) regularly distributed over the external surface of the upper end of the slider (4), that is to say - say in square. It is obvious that the number of centering projections (43a, 43b, 43c, 43d) may be different. However, it will be noted that three centering projections positioned in a triangle constitute a minimum configuration for optimally guiding the movement of a cylindrical element inside a tubular element.
• the centering of the lower part of the slider (4) is achieved, on the one hand, by the cooperation between the first guide projections (41a, 41b) and the guide grooves (21a, 21b), and on the other hand, by the cooperation between the second guide projections (46a, 46b) and the helical grooves (36).
• the centering projections (43a, 43b, 43c, 43d) are also able to cooperate by contact with an internal rim, forming stop means (37), integral with the upper end of the tubular body (3).

• the guide means (20) also comprise longitudinal and rectilinear storage grooves (23a, 23b), which are capable of receiving the centering projections (43a, 43b, 43c, 43d) when the cursor (4) is in the lowered position retracted inside the base (2).
• the first guide projections (41a, 41b) have dimensions greater than those of the storage grooves (23a, 23b) which are intended to receive the centering projections (43a, 43b, 43c , 43d).
• This feature allows advantageously to prevent the first guide projections (41a, 41b) from engaging in the storage grooves (23a, 23b), this in order to guarantee correct mounting of the rotary case during its manufacture or after any operation of disassembly.
• the storage grooves (23a, 23b) have in fact a substantially smaller length than the guide grooves (21a, 21b).
