PROTECTION AND CAPPING ASSEMBLY OF A DISPENSER

  OF PASTY PRODUCT WITH AN ECCENTRIC DISTRIBUTION ORIFICE

  The present invention relates to a

  protection and closure assembly for a dispenser

  ty product, for example a distributor

  piston and dispenser toothpaste dough dispenser

  tribution without air intake, having a distribution orifice

offset tribute.

  Many dispensers

  tifrice are constituted, on the one hand, by a rigid container part, generally cylindrical, and on the other hand, by a distribution cap, which covers said container part and is connected to the means of the distributor allowing the ejection of the product. This distribution cap most often includes a distribution channel whose free end,

  off-center, defines the dispensing orifice.

  Protective covers are already known for such dispensing dispensers, which, when dispensers are not used, cover the dispensing caps. These protective covers have for

  essential function of protecting the protective cap

  contribution against external shocks which could deteriorate it. They have no function of blocking the dispensing orifice. The material in the channel, directly in the open air or in contact with the air included under the protective cover tends to dry in the ejection channel, to dirty it and to obstruct it. Some toothpaste dispensers are presented for sale, that is to say, before the first use by the consumer, provided with a

  small capsule blocking the dispensing orifice

  tion. This small capsule, which is a separate piece

  attached to the rest of the device, essentially serves to prevent the material contained in the pouring dispenser from drying out during storage before sale and

  throws, generally, the first use.

  There are already, for containers having a shape of revolution and an orifice centered on their axis, covers intended to accompany said containers throughout their use and having both a protective function and a plugging function. The bottom of the hood is provided, for example,

  an inner protuberance that fits, in posi-

  plugging, in the dispensing orifice and shut off. To associate a protective cover and a container in the plugging position, it is generally sufficient to thread the cover on the neck of the container in any angular position, then, for example, to make the screw threads cooperate.

respective if they exist.

  However, the use of pro-

  similar sections for receptacles with an eccentric opening is much less convenient, since it is necessarily necessary for the closure members to be present exactly in the angular position

  allowing to assemble with the outlet orifice.

  To facilitate this positioning, polarization means are often used which only allow one part to be engaged on the other in a predetermined angular position. Such a solution has the drawback of forcing the user to grope around to find the suitable angular position which allows a

  engagement in the means of polarization.

  The present invention provides a solution which makes it possible to avoid or at least reduce such trial and error. The protective cover and the distribution cap are provided with suitable means for guiding the assembly and driving the outlet orifice.

  To better understand the purpose of

  the invention, we will now describe, purely

  illustrative and nonlimiting, a method of

  realization shown in the accompanying drawing.

  In this drawing: - Figure 1 is an exploded perspective view of a protective cover and a dispensing cap mounted on a container;

  - Figure 2 is a sectional view longitu-

  dinal of the protective cover; - Figure 3, finally, is a sectional view along line 111-111 of Figure 2 of the same cover

tributor.

  The protective cover 1 has a wall v2640586 4 closed on itself and terminated at one of its ends by a flat bottom 5, its other end being free. Towards its free end, the wall 4 is a cylindrical sleeve 6. The bottom 5 has a shape which is defined by a circle 7, of the same axis as the sleeve 6 and of slightly smaller diameter, at the periphery of which are distributed three ear receptacles 8, 120 'from each other, identically extending the bottom 5. These ear receptacles 8 are delimited at their ends opposite to the circle 7 delimiting the bottom 5 by the arcs of a circle of the same

  center and of the same diameter as the sleeve 6.

  The ears 8 are connected two by two by the walls of the guide ramps 10 which extend the lateral ends 9, facing each other, of said ears 8. The guide ramps 10 are the branches of bands, of constant thickness, having substantially the shape of a tooth or a V, the slightly rounded tip of which is situated towards the free end of the protective cover 1 and the ends of which are the lateral ends 9 of the ears 8. The wall 4 of the cover protection 1 connects cylindrically the inner contour of these guide rails 10 to the circle 7, thus defining three

  fins 11. In addition, the wall 4, extending cylin-

  only the sleeve 6, connects the external ends of the guide ramps 10 with the periphery of the bottom 5 delimited by the arcs of a circle defining the ears 8. In this way, two fins there determine by their guide ramps 10 juxtaposed a closed groove 12 on one side by the wall 4 and ending on the bottom 5 at the ears 8. In a variant, not shown, the surfaces of the fins 11, directed towards the inside of the cover 1, are

slightly domed.

  The bottom 5 is provided laterally, on its inner surface, in the ear receptacles 8, with three pins 13. These three pins 13 are small parbllepipeds having two of their surfaces slightly arched and parallel to the cylindrical parts of the

  a wall 4, two other of their surfaces being sensitive-

  ment parallel to the parts of the guide rails towards the lateral ends 9 of the ears 8, their other surfaces being parallel to the bottom 5. In a variant not shown, the bottom 5 is thicker on

  its surface delimited by the circle 7 only on the hous-

  in ear 8, the height of the pins 13 along the axis of the cover I being substantially equal to the thickness of the bottom 5 on its surface delimited by the circle 7; each pin 13 is then surrounded by a

small annular groove.

  The dispensing cap 2 has a

  cylindrical frame 14 whose cross section is a circle

  key slightly smaller in diameter than the circle 7. The interior of this frame 14 is intended to contain the means for actuating the dispenser. At one end of this frame 14, opens a push button 15 connected to the means for actuating the dispenser. -This push button 15 is a cylinder which slides coaxially in the frame 14, its end remote from said frame being limited by a flat surface, slightly inclined with respect to one on: perpenicular ace At the axis of the frame 14, intended for

  The other end of the frame 14 is connected by a small annular surface 16 to a neck 17 which is a hollow cylinder coaxial with the frame 14, the inner surface of which is fitted onto the cylinder of the container 3. This neck 17 has slightly smaller dimensions to those of the sleeve 6. It is terminated in its part closest to the container 3 by a rim 18 which is an annular flange whose thickness is that of the wall 4. The distribution cap 2 is provided, along the frame 14, a distribution chimney 19 opposite the highest point of the push button 15

  when the container 3 and the cap 2 are vertically

  cals. This chimney 19 is a conduit parallel to said frame 14. Its walls have substantially the shape of an elongated parallelepiped, one of the walls in length being slightly arched and extending the neck 17, the wall facing it partially matching the wall

  of the frame 14. This chimney 19 opens perpendicular to

  at one of its ends on the annular surface

  laire 16. Its other end is free and delimits the distribution opening 20 having a shape allowing it to receive exactly the pins 13, the thickness of the walls of this chimney 19 being smaller than the minimum distance separating the wall 4 from the pins 13, so that said chimney 19 can

be placed in the grooves 12.

  When you want to close the pro-

  tection 1 on the dispensing cap 2, the sleeve 6 is initially engaged on the part of the dispensing cap 2 opposite the container 3, and this. regardless of its angular position by

  port to another. The edges 21 of the distribution chimney

  bution 19, which delimit the opening 20, form pipe protrusions and end up on the wall 4, then on the guide rails 10. The chimney 19 is then gradually guided in a groove 12, until the pin 13 associated with said

  groove 12 is inserted into the dispensing opening 20.

  During this maneuver, the sleeve 6 descends coax-

  ialally along the dispensing cap 2. Its possibilities of transverse displacements are reduced as and when it passes over the push button 15, then over the frame 14 and finally over the neck 17, on which it is inserted with a slight tightening, after having been stopped in its axial displacement by

the edge of the collar 18.
