Definitions

  • the present invention relates to a packaging for powdered product which comprises an improved closure device.
  • the device described in this patent comprises a lower housing provided with an upper cover and, at its lower part, provided with serrated slots, a flange being provided between the lower edge of this housing and the cover.
  • the device further comprises a lower housing which can slide relative to the upper housing. It comprises a first upper cylindrical part, a second lower cylindrical part, and an intermediate conical part.
  • the device further comprises a conical shutter which is fixed to the lower part of the upper case and which cooperates with the lower case when the device is closed.
  • this obturator The role of this obturator is to allow the flow of the pulverulent product which is in the upper case, when the device is open, flowing along the walls of the conical obturator which is then separated from the lower container and the pulverulent product passing through the slots in the upper case.
  • the shutter further comprises a branch directed from the upper housing to the lower housing.
  • the function of this branch is to prevent inadvertent opening of the device. Indeed, when the device is placed on a plane, even if the user presses on the cover of the upper case, the branch which rests on the continuous plane opposes the opening.
  • This device does not allow total reliability. Indeed, the branch does not oppose the opening that is to say, the separation of the upper housing and the lower housing, when the user performs axial pressure only when the device rests on a surface. The branch does not allow correct closure when the user lifts or leans the device and by such a movement and a simultaneous push, the user can open such a device.
  • the invention aims to overcome these drawbacks.
  • An object of the invention is to provide a packaging for a pulverulent product, in particular a caustic product which cannot be opened inadvertently and therefore comprises a safety closure.
  • the stopper can, according to one embodiment of the invention, be located on the lower case and the projection can be located on the upper case.
  • the stopper and the projection may also be located in the internal space between the external wall of the upper housing and the internal wall of the lower housing.
  • the stopper and the projection can be located on the outer walls of the housings.
  • the stopper is a pivot and the discontinuous projection is a clip or according to a second embodiment, the stopper is a longitudinal tab, the discontinuous projection being a flange disposed on the outer wall of the upper housing, the free edge of the tab abutting the projection.
  • the shutter can be an integral part of the upper housing, namely the shutter and the upper case can be molded in one piece.
  • the shutter has a conical shape and does not have an axial branch.
  • Figure 1 there is shown a device according to the invention in the closed position.
  • the device 1 consists of a cylindrical upper housing 2 with an axis of rotation xx, closed at its upper end 3 by a cover 4 and comprising at its lower end 5 orifices 6 formed in the wall.
  • a lower housing 7 is co-axial with the upper housing 2 and it consists of an upper part 8, a lower part 9 and a middle part 10.
  • the upper part is cylindrical with a revolution of axis xx, the the lower part is also cylindrical with an axis xx, the radius r of the upper part being less than the radius R of the lower part 9.
  • the middle part 10 is conical.
  • the lower case 7 is open at its two ends 11-12 and it can slide relative to the upper case 2.
  • the device further comprises a shutter 13 placed inside and cooperating with the upper housing 2.
  • the shutter 13 is provided with means for securing with the free edge 15 of the lower end portion 5 of the upper housing 2, l 'assembly of the upper housing 2 and shutter 13 can slide axially between a closed position (shown in Figure 1) and a maximum open position (shown in Figure 2').
  • the means 14 for securing the shutter 13 may consist of a groove 16 and an adjoining rim 17, the rim 17 engaging in an internal groove 18 of the lower housing while the groove 16 cooperates with studs arranged inside the lower end portion 5 of the upper housing 2.
  • the upper housing 2 and the shutter 13 can consist of a single piece, for example of a piece which is molded or injected, the shutter 13 then no longer having a groove 16 and comprising only a circular rim 17.
  • This rim 17 constitutes, with the internal groove 18, means for temporarily fixing the upper housing 2 shutter assembly 13 with the lower housing 7.
  • the device also comprises means 19 for stopping the axial sliding of the upper casing 2 assembly shutter 13 relative to the lower casing 7.
  • the stopping means 19 When the stopping means 19 are active, they determine the maximum opening position. (figure 2).
  • the means 19 for stopping the axial sliding consist of the upper free edge 20 of the upper part of the lower housing 7 and by a projection 21 disposed substantially halfway up the upper housing 2.
  • the projection 21 is placed outside the upper housing 2.
  • the device according to the invention is such that it includes means 22 for locking the packaging in the closed position (see FIGS. 1 and 5).
  • the locking means 22 have the function of preventing the axial sliding of the upper housing 2 relative to the lower housing 7, while allowing the axial pivoting of the upper housing 2 assembly shutter 13 relative to the lower housing 7.
  • the locking means 22 are constituted by at least one stop 23 coming into abutment on the circular projection 21 which comprises at least one discontinuity 26, the stop 23, when it is not not opposite discontinuity 26 preventing axial sliding.
  • the flange 21 therefore approaches the free edge 20 and when the flange 21 abuts against the edge 20 of the housing 7, the two housings 2 and 7 are brought as close together as possible and the device is in its maximum open position (FIG. 2 and 4).
  • the stopper 23 is located on the lower case 7 and the projection 21 is located on the upper case 2. But one can also provide the reverse, namely that the stopper 23 is located on the upper housing 2 and the projection 21 is located on the lower housing 7.
  • the stopper 23 is a longitudinal tab and the discontinuous projection 21 is a flange disposed on the outer wall of the upper housing 2, the upper free edge 24 of the tab coming into abutment on projection 21.
  • FIGS 4 and 5 show another embodiment of the present invention.
  • the device shown in FIG. 4, in the closed position, includes a stopper and a projection located in the internal space between the external wall of the upper housing 2 and the internal wall of the lower housing 7.
  • the stopper is located on the outer wall of the upper housing 2, while the projection is located on the inner wall of the housing 7.
  • the stopper is a stud 24 and the projection is a clip 25, the clip 25 being arranged on the internal wall of the lower housing 7.
  • the safety device constituted by the blocking means 22 of the packaging according to the invention makes it possible to produce the shutter 13 in the form of a cone, the apex of which is directed towards the upper housing 2.
  • Such a shutter 13 does not Unlike the prior art, therefore, there is no advanced tip which, when the device is placed on a continuous plane, rests on the latter in order to prevent opening of the packaging according to the invention.
