Container for cosmetic product provided with a lid guided by an internal rod

Abstract

The container for cosmetic product, suitable for use on the go, includes a base and a compartment for the product, with an opening surrounded by a peripheral edge which extends radially from a partitioning side wall to a peripheral wall of the base. The lid of the container hermetically covers this opening and is retained when an associated perpendicular rod, traversing the peripheral edge, is in the position of maximum insertion, therefore proximal to a container bottom. A driving force on the outside of the lid makes it possible to overcome the retention, by moving the lid along an inclined upper surface of the peripheral edge, compatible with a rising of the rod which guides the lid displacement that is generally parallel to the opening plane. The container may be part of a cap sealing a packaging assembly of larger volume.

1 . A container for cosmetic product, comprising:
 a base comprising a lower surface and a peripheral wall extending from the lower surface and upwards to define an inside volume,   a receiving space for the cosmetic product, the receiving space being accessible via an upper opening,   a peripheral edge, the upper opening being surrounded by the peripheral edge,   a lid, movable relative to the base and to the peripheral edge between a closed position, in which the lid prevents access to the cosmetic product, and an open position, in which the cosmetic product is accessible via the upper opening,   a sealing system preventing the cosmetic product from coming into contact with an external environment when the lid is in the closed position,   an opening/closing system, suitable for causing the lid to transition between the open position and the closed position, comprising a rod located at the rear of the lid and housed in a hole of the peripheral edge, the rod cooperating with the lid and extending from the lid towards the lower surface of the base while being configured to move transversely relative to the lower surface of the base, in order to transition between a position proximal to the lower surface and a position distal to the lower surface, the lid in the closed position being surrounded by the peripheral edge,   a restraint system forcing the lid to the closed position by urging and/or maintaining the rod towards its proximal position, so that the lid cannot transition from the closed position to the open position without a force or thrust being exerted on an exterior portion of the lid forming an outer surface of the container; and   wherein, for the proximal position, the lid rests on an upper surface of the peripheral edge which has a downwardly sloping incline towards an edge of the upper opening, the lid being able to slide on the upper surface along the incline of the upper surface so as to cause a transverse displacement of the rod from and/or to the proximal position.   
     
     
         2 . The container according to  claim 1 , wherein the rod is configured for:
 pulling and adjusting height of a closure portion that is part of the lid and which completely covers the upper opening in the closed position, the closure portion fitting into the base by being housed within the inside volume when the rod is in the proximal position; and   protruding axially above the peripheral edge when the rod is in the distal position, while enabling the rear of the lid to be movable above the peripheral wall.   
     
     
         3 . The container according to  claim 2 , wherein when the rod is in the proximal position with the upper opening completely covered by the lid, an outer uppermost surface of the lid is flush with a top of the peripheral wall of the base. 
     
     
         4 . The container according to  claim 1 , wherein, in the closed position, an inner surface of a peripheral end of the lid rests on the upper surface of the peripheral edge, and
 wherein the lid has a closure portion configured to move, in response to the driving force or thrust exerted on the outer portion of the lid in the closed position, in a translational movement induced by a sliding between said respective inclines of the inner surface of the peripheral end of the lid and of the upper surface of the peripheral edge, until reaching a raised position resulting in a transverse movement of the rod relative to the lower surface of the base, causing the rod to transition from the proximal position to the distal position and thus causing the lid to transition between the open position and the closed position.   
     
     
         5 . The container according to  claim 4 , wherein the inner surface of the peripheral end of the lid and the upper surface of the peripheral edge have a matching incline.

 opposite to the lower surface;   and defines the upper opening, the upper opening extending entirely within the inside volume; and   wherein the peripheral edge, which is annular, has a shape that is generally frustoconical or is a sphere portion bounded by two of its parallels, rising radially outwards from the annular upper axial end towards a top of the peripheral wall.   
     
     
         7 . The container according to  claim 1 , wherein the lid includes the rod which defines an axis of rotation of the lid;
 and wherein, in order to transition between the closed position and the open position, the lid and the rod are further able to be rotated about the axis of rotation of the lid by said force or thrust, exerted at a front of the lid and in a direction transverse to the axis of rotation and which is perpendicular to a straight line connecting the rear of the lid to the front of the lid,   sliding of the lid on the inclined upper surface of the peripheral edge being induced by rotation.   
     
     
         8 . The container according to  claim 7 , wherein the opening/closing system further comprises a guide region, fixed, formed by a guide having a cylindrical structure which surrounds the rod, the guide region cooperating with an anchoring portion included in or made integral with the rod, at a lower end of the rod, whereby an axial displacement of the lid during rotation about the axis of rotation is dependent on the movement of the anchoring portion relative to the guide region. 
     
     
         9 . The container according to  claim 8 , wherein a lug is engaged in a helical track, with the helical track being provided on the rod and the lug provided on the guide having the cylindrical structure, or vice versa.
