Case for cosmetic products

Abstract

A cosmetic case includes a base, a cover, a seal and a closing/opening means, the base and the cover being hinged against each other via a pivot connection, the case being capable of occupying two separate positions, a closed position and an open position. The closing/opening means includes an additional part which is in slide connection or in pivot connection with the cover, and one or more locking means connected to the additional part, respectively to the base, the locking means forming a multipoint locking applying a sufficient pressure on a seal when the case is in the closed position such that the sealing against impurities and fluids between the inner and outer environments of the case, in the closed position, is total under the normal temperature and pressure conditions (NTPC), the seal being presented in the form of a material strand.

What is claimed is: 
     
         1 . A cosmetic case comprising a base, a cover, a seal and a closing/opening means, the base and the cover being hinged with respect to one another by means of a pivot connection, the case being capable of occupying two separate positions, a closed position wherein the cover is held in position on the base by the closing/opening means and an open position wherein the cover is free to pivot with respect to the base, said closing/opening means comprising:
 an additional part which is in slide connection or in pivot connection with the cover,   a plurality of locking means connected to the additional part, respectively to the base, said locking means being designed to each cooperate with a housing provided in/on the base, respectively in/on the additional part, the plurality of locking means forming, with said housings, a multipoint locking,   the seal being provided on the surface of the base, respectively of the cover, so as to undergo flattening by the cover, respectively by the base, when the case is in the closed position,   wherein the multipoint locking applies sufficient pressure on the seal when the case is in the closed position such that the sealing against impurities and fluids between the inner and outer environments of said case, in the closed position, is total under the normal temperature and pressure conditions (NTPC).   
     
     
         2 . The case according to  claim 1 , wherein the actuation of the closing/opening means is achieved by moving the additional part with respect to the cover so as to engage/disengage the locking means from their respective housing, such that the passage from the open position to the closed position of the case, and conversely, does not provoke any friction on the seal. 
     
     
         3 . The case according to  claim 1 , wherein the connection between the additional part and the cover is ensured by a cooperation of technical forms present, on the one hand, over the outer periphery of the cover and, on the other hand, over an inner circumference of the additional part, the locking means and their respective housing being regularly distributed over the outer periphery of the cover and/or over the inner circumference of the additional part. 
     
     
         4 . The case according to  claim 1 , wherein the seal is presented in the form of a material strand. 
     
     
         5 . The case according to  claim 1 , wherein the seal is returned to the surface of the base, conversely to the surface of the cover. 
     
     
         6 . The case according to  claim 5 , wherein the seal is held in position by surface gluing. 
     
     
         7 . The case according to  claim 1 , wherein the seal is over-molded with the base, conversely with the cover. 
     
     
         8 . The case according to  claim 3 , further comprising a means for assisting the opening of the case intended to automatically remove the cover from the base during the passage of the case from the closed position to the open position, without requiring the exterior user to intervene. 
     
     
         9 . The case according to  claim 8 , wherein the seal serves as a means for assisting the opening. 
     
     
         10 . The case according to  claim 1 , wherein the locking means are hooks. 
     
     
         11 . The case according to  claim 10 , wherein the hooks have a technical form comprising a slope intended to facilitate the entry of said hooks into their respective housing during the passage from the open position to the closed position of the case. 
     
     
         12 . The case according to  claim 1 , wherein the base is adapted to receive:
 a cosmetic product, in particular comprising a volatile and/or damp composition, and a cosmetic product applicator, and wherein the cover is structured to receive a mirror of the pocket mirror type.
