Definitions

• the present invention relates to the mechanical retention in rotation and traction of constituent elements of a rotating cosmetic case of the type used to contain cosmetic products, such as a stick of lipstick or lip creams.
• a rotating cosmetic case is generally equipped with a removable cover which is assembled in correspondence of a lower packaging.
• the lower conditioning acts as a dressing facilitating the gripping of the holster and is fitted on a mechanism consisting of a slider receiving a stick of lipstick or lip creams, which usually comes to encase in a sheath slide which is itself encased in a spiral envelope.
• the slider is equipped with lugs engaged in the slideways of the sheath and extending into the helical grooves of the spiral envelope. Rotation of the lower package causes the slider to move in a simultaneous rotational and translational movement, allowing access to the lipstick stick or labial creams.
• the concentric elements of synthetic material of the rotating mechanism are embedded in a metal sheath.
• the holding of this assembly is generally provided by glue.
• glue generates in addition to problems related to its handling and the application of a precise amount to avoid burrs and the creation of bead glue that may interfere with the proper operation of the mechanism, setting times of the glue and evaporation of relatively long volatile products, which requires an organization of the particular assembly line and reduces the rate of production.
• Effective mechanical restraint of these elements is required to limit the problems of disconnection of the metal jacket by traction and rotations, excessive and repeated, related to the handling of a holster including the removal of the protective cover or the excessive stress of the mechanism at the end of the race.
• a cosmetic case rotating according to the invention comprises an outer metal sleeve fitted and mechanically retained to a plastic sheath at a time by at least one rotational locking means and at least one traction locking means, a locking means in rotation consisting of a cutout opening outwardly at the lower end of the cylindrical wall of the metal jacket, the cutout being mounted together with a protrusion molded in the sheath, while the pulling locking means consists of at least one orifice in the lower part of the cylindrical wall of the metal jacket delimiting with the lower end thereof an inwardly directed wall portion facing a housing located in the sheath.
• the cutout is trapezoidal.
• a transverse face of the cutout arranged radially relative to the cylindrical wall of the metal sleeve abuts against a face also arranged radially of the projecting profile of the sheath.
• the wall portion is directed inwardly and has at least one recess; while at least one recess has a protruding profile
• the upper end of the wall portion facing the interior of the metal jacket is in contact with the upper end of the housing of the sheath.
• the lower end of the inwardly directed wall portion of the metal jacket coincides with the lower end of the housing of the sheath.
• the height of a wall portion is less than the height of a dwelling
• two traction locking means are located diametrically opposite.
• the sheath is a spiral envelope which comprises at least one helical groove corresponding to a first zone, which will be described as a negative zone, and a second zone which will be described as a positive zone, corresponding to the zone arranged between two portions of helical groove, while at least one housing is located in correspondence of at least one positive zone.
• Figures la to 3b are views of a cosmetic case and these constituent elements, according to one embodiment.
• Figures la and lb are front views of a mechanism rotating in two angular positions.
• Figures 2a and 2b are front views of a metal jacket in two angular positions.
• Figure 2c is a magnification view of Figure 2a.
• Figure 3 is a perspective view of a metal jacket.
• Figures 4a and 4b are front views of a spiral envelope according to two angular positions.
• a cosmetic case according to the invention comprises at least one rotational locking means (3) independent of at least one means of locking in tension (4) of a metal jacket (1) and a sheath (2) of synthetic material.
• the cosmetic case comprises a rotational locking means (3) and two traction locking means (4) arranged diametrically opposite to optimize the distribution of forces involved during the tensile stress.
• the rotational locking means (3) is articulated between the cooperation of at least two abutment faces arranged radially or substantially radially with respect to the concentric elements to which they are attached, while the traction locking means (4). is presented by the contact of at least two faces also in abutment, but arranged parallel or substantially parallel to the bottom of the cosmetic case, namely perpendicular to the axis of rotation of the rotating mechanism
• the rotational locking means (3) consists of the collaboration of a cutout (5) made at the lower end of the cylindrical wall of the metal jacket (1) with a molded projection ( 6) in the sheath (2) so that at least one respective lateral face of the cutout (5) and the molded projection (6) abut against each other, while each of the side faces is oriented so that their respective planes are oriented radially or substantially radially, namely making an acute angle with the general axis of rotation of the mechanism.
• the general profile of a molded projection (6) is intended not to exceed the outer profile of the metal jacket (1), namely the outer profile of the molded projection (6) matches that of the metal jacket (1). ).
• the abutment side faces of the cutout (5) and the molded projection (6) are at an angle with respect to the general axis of rotation of the mechanism of between 1 and 45.degree., Preferably between 1 and 20.degree. °, as shown in Figure XX.
• This orientation of the faces one against the other allows a facilitated insertion of the cutout (5) at the periphery of the molded projection (6), during the fitting of the metal jacket (1) on the sheath (2) in synthetic material.
• the cutout (5) is trapezoidal. According to the preceding feature the lower ends of the trapezoidal cut (5) are flared, ie rounded.
• the molded projection (6) has a shape corresponding to that of the cutout (5), namely that if the cutout (5) is trapezoidal, the molded projection (6) is also trapezoidal; in such a way that their respective lateral faces come into contact and abutment, blocking all the rotation games.
• the rotating cosmetic case also comprises at least one translation locking means (4).
• translational locking means (4) is provided by a wall portion (8) located at the lower end of the metal jacket (1), which is curved towards the interior and comes embedding in a suitable housing (9) arranged in the sheath (2) made of synthetic material.
• the wall portion (8) is formed by an orifice (7) located substantially at the lower end of the metal jacket (1).
• the wall portion (8) is therefore delimited by at least the lower end of the orifice (7) and the lower end of the metal jacket (1).
• the shape of this wall portion (8) is advantageously longitudinal and thin, so that it is intended to be flexible to allow it to twist inward without damaging the overall profile of the metal jacket (1).
• an orifice (7) has an oblong shape, so that the wall portion (8) has a rectilinear part, but it could be otherwise an orifice (7) to a parallelepiped shape even circular or ovoid.
• the wall portion (8) has at least one recess (10), preferably at least two recesses (10), their (s) fuseil (s) is / are advantageously protruding). Note that the / the upper faces of the wall portion (8) are in contact or even placed under stress against the upper face of the housing (9), when remolding the metal jacket (1) around the sheath (2).
• the height of a wall portion (6) is less than the height of a housing (9), in order to limit the force to be applied to create a recess (10), without altering the cylindrical profile of the outer shirt.
• the sheath (2) of synthetic material is a spiral envelope which comprises at least one helical groove corresponding to a first zone, which will be qualified as a negative zone, and a second zone which will be described as a zone positive, corresponding to the zone arranged between two portions of helical groove, while at least one housing (9) is located in correspondence of at least one positive zone.
