Packaging device with container with threaded neck and screw closure member

Abstract

A device for packaging a product, in particular a cosmetic product, having a container for containing the product, provided with a threaded neck of longitudinal axis (Z), at least one screw thread having, on the side of the free end of the neck, a thread starting point, and a closure member for closing the container that is arranged to be screwed onto the neck, the closure member having at least one stop arranged to come to bear against the thread starting point at the end of the screwing of the closure member onto the neck of the container to block the rotation of the closure member.

1 . A device for packaging a product having:
 a container for containing the product, provided with a threaded neck having a longitudinal axis, at least one screw thread having, on the side of the free end of the neck, a thread starting point, and   a closure member for closing the container that is arranged to be screwed onto the neck, the closure member having at least one corresponding stop arranged to come to bear against the thread starting point at the end of the screwing of the closure member onto the neck of the container to block the rotation of the closure member   at least one screw thread having, on the side opposite the free end of the neck, a thread end point and having a thread interruption between the thread starting point and the thread end point,   the closure member having at least one elastically deformable tongue arranged to engage at least partially in the thread interruption during the screwing of the closure member onto the neck of the container and generate a tactile sensation and/or the emission of an audible click.   
     
     
         2 . The device according to  claim 1 , the thread starting point having a stopping surface against which the corresponding stop comes to bear, this stopping surface being substantially parallel to the longitudinal axis of the neck. 
     
     
         3 . The device according to  claim 1 , the thread interruption being situated between the thread starting point and the halfway point of the height of the thread. 
     
     
         4 . The device according to  claim 1 , the container having, at the base of the neck and around the latter, a shoulder, the latter not having a stop that forms a protrusion with respect to the shoulder and against which the closure member comes to bear at the end of the screwing thereof. 
     
     
         5 . The device according to  claim 1 , the container being made, at least in part, of glass. 
     
     
         6 . The device according to  claim 1 , said at least one stop having a surface intended to come to bear against the thread starting point, this surface extending substantially parallel to the longitudinal axis of the closure member. 
     
     
         7 . The device according to  claim 1 , the tongue being attached to the closure member by only one of its ends. 
     
     
         8 . The device according to  claim 1 , the tongue having, on the inside, an upstream flank and a downstream flank that are oriented obliquely in the radial direction, the upstream flank engaging first in the thread interruption during the screwing of the closure member, and the downstream flank. 
     
     
         9 . The device according to  claim 1 , the closure member having an internally threaded mounting skirt, arranged to be screwed onto the neck, provided with at least one perforation, the tongue extending at least partially into this perforation. 
     
     
         10 . The device according to  claim 1 , the closure member having an internally threaded mounting skirt, arranged to be screwed onto the neck, provided with at least one perforation, this perforation preceding the stop in the direction of screwing of the closure member onto the container. 
     
     
         11 . The device according to  claim 1 , the closure member having a stem holder to which a stem bearing a member for applying the product is fastened, the stem being inserted into the container when the closure member is screwed onto the container. 
     
     
         12 . The device according to  claim 1 , the screwing of the closure member onto the container being done in less than one turn around the longitudinal axis of the neck.
