DETAILED DESCRIPTION

Figures 1, 2 and 3 show a sectional view of a container of stick product according to one aspect of the invention in three separate configurations, respectively closed, during opening and open.

The container 1 as shown in Figures 1 to 3 comprises: - a tubular body 10, - an inner sleeve 20 slidably mounted in said tubular body 10, typically having a hollow tube shape. - A cup 30 slidably mounted in said sleeve 20, supporting a stick of product 40, typically a grape lipstick. The cup 30 typically has a hollow tube shape. - An inner guide 50 disposed in said tubular body 10, and wherein are disposed said sleeve 20 and said cup 30, the sleeve 20 and the cup 30 being rotatably mounted in said inner guide 50. The inner guide 50 typically has a shape of hollow tube in which the sleeve 20 and the cup 30 slide. - An external covering 60 in which are housed said tubular body 10, inner sleeve 20, cup 30, product stick 40 and inner guide 50 The container 1 may also comprise a counterweight 70 disposed in the casing 60, thus allowing the container 1 to be ballasted so that the user can handle a product having a sufficient mass. Also defined in Figure 1 a longitudinal axis Z of the container, which typically corresponds to its axis of revolution if the container 1 is of generally cylindrical shape.

The tubular body 10 has a guide portion, on its inner face, this guide portion being for example a threaded portion, comprising a first section 11 and a second section 12. In the embodiment shown, the tubular body 10 comprises a proximal end 13 and a distal end 14 which will be presented later and marked in Figure 4, the first section 11 being adjacent to the proximal end 13 and the second section 12 adjacent to the distal end 14. A first helical ramp 16 extends over all said guide portion, thus defining a single tapping on all said portion. On the first section 11 of the guide portion, the first helical ramp 16 has an incrementation thereby defining a double helical ramp on said first section, on which are therefore the first helical ramp 16 and a second helical ramp 17 distinct from the first helical ramp. This double helical ramp is typically formed of two adjacent helical ramps, similarly not, and having a distinct inner diameter.

The pitch of a helical ramp is the distance between two consecutive vertices of the same helix. The internal diameter of a helical ramp is defined as the maximum diameter of an element having a thread complementary to said tapping.

Figure 4 shows a longitudinal sectional view of the tubular body 10 taken in isolation, and identifies said first and second sections 11 and 12 of the guide portion. It is observed in this figure that the first helical ramp 16 which extends both on the first 11 and second section 12 of the tubular body has an internal diameter greater than the second helical ramp 17 which extends only on the first section 11 of the tubular body 10. Thus, an indexing means, that is to say a means for adjusting the relative positioning between several parts adapted to cooperate with the second helical ramp 17 advantageously have dimensions that do not allow that it cooperates with the first helical ramp.

The inner sleeve 20 and the cup 30 comprise indexing means 21 and 31 cooperating respectively with the second helical ramp 17 and with the first helical ramp. In the embodiment shown, the inner sleeve 20 and the cup 30 each comprise two indexing means arranged on either side of the inner sleeve 20 and the cup 30, which improves the relative positioning of these elements. elements with respect to an embodiment in which they would comprise a single indexing means. For example, in the case where the indexing means are fingers 21, the finger 21 of the sleeve 20 typically has a radial dimension with respect to the axis of rotation Z of the tubular body 10 less than a radial dimension of the finger 31 of FIG. the cup 30 relative to the axis of rotation Z.

The tubular body 10 as illustrated then has two identical threads staggered about 180 ° in a plane perpendicular to the longitudinal axis Z of the tubular body 10, each of these threads comprising a first and a second section as previously described and allowing to engage the two indexing means 21 of the sleeve 20 and the two indexing means 31 of the cup 30. The inner guide 50 comprises a groove 52 in which said sliding means 21 and 31 of the sheath 20 slide and of the cup 30, said groove 52 being rectilinear and extending in the longitudinal direction of the container 1.

The covering 60 comprises a gripping portion 61, and a cap 62 which are both fixedly mounted on the inner guide 50, typically by gluing, welding or force-wrapping.

The cap 62 defines an opening 63 of the container 1, closed by one or more valves 64 pivotally mounted on said cap 62. The valve or valves 64 are associated with resilient return means 65 adapted to maintain them by default in a position in which they close off the opening 63 of the container 1, and make it possible to rotate them so that they give access to said opening 63. Several variants can be envisaged in order to close the opening 63 of the container 1. It is possible, for example, to assemble a single valve on the cap 62, which covers all or part of the end of the container 1 having the opening 63. Alternatively, for an opening 63 of circular section, it can be closed by means of several valves 64 typically having a section of semicircle, third or quadrant depending on the number of valves 64 used. The elastic return means as shown are slats 65 of elastic material disposed in the extension of the inner guide 50. These slats 65 are connected to the valves 64, for example inserted into housings in said valves 64. When opening valves 64, the slats 65 are bent and thus exert an elastic return towards their rest position in which they are substantially parallel to the longitudinal axis Z of the container 1, and thus keep the valves 64 in a position where they close off opening 63 of the container 1. These strips 65 are typically made of plastic material; they are then advantageously molded with the inner guide 50. Alternatively, the lamellae 65 may be made of metal material; they are then typically welded or glued to said internal guide 50.

The tubular body 10 is pivotally mounted in said casing 60 and comprises a ring 15 projecting from the outer casing 60 so that a user can actuate said ring 15 in order to cause said tubular body 10 to rotate with respect to the casing 60. dressing 60 and inner guide 50.

According to an advantageous embodiment, the tubular body 10 and the ring 15 are formed in one piece.

The operation of the container 1 is described below with reference to FIGS. 1 to 3 in order to describe the opening of the container 1.

Figure 1 shows the container 1 in the closed position; the valves 64 close the opening 63 of the container 1. The sleeve 20 and the cup 30 are set back relative to the opening 63 of the container 1, and their respective indexing means 21 and 31 are substantially at the level of the proximal end 13 of the tubular body 10. The user grasps the container 1 by its covering 60, and drives the tubular body 10 in rotation by means of its ring 15 in a first sense that is called the opening direction. The tubular body 10 then rotates about its axis, without translating relative to the covering 60 and the inner guide 50. This rotation of the tubular body 10 causes the indexing means 21 and 31 of the sleeve 20 and the cup 30 in motion according to the first and second helical ramps of the tubular body 10. However, the indexing means 21 and 31 of the sleeve 20 and the cup 30 are arranged in the groove of the inner guide 50, and can not move that along the longitudinal axis Z of the container 1, which is also the axis of rotation of the tubular body 10. Consequently, causing the tubular body 10 to rotate will cause the sheath 20 and the cup 30 to move. in translation along the longitudinal axis Z of the container 1.

The displacement is broken down into several stages. In a first step, which corresponds to the displacement of the indexing means 21 and 31 of the sheath 20 and the cup 30 according to the first and the second helical ramp, that is to say along the first section 11 of the body tubular 10, the sleeve 20 and the cup 30 move together, to the extent that the first and second helical ramps have the same pitch. During this movement, the sleeve 20 comes into contact with the valve or valves 64, and rotates them to release the opening 63 of the container 1. The sleeve 20 in which the cup 30 is housed then exits the container 1 by its opening 63, as illustrated in Figure 2.

In a second step, once the indexing means 21 and 31 of the sleeve 20 and the cup 30 have moved along the entire first section 11 of the tubular body 10 and reach the second section 12, only the cup 30 is displaced. due to the movement of the tubular body 10. In fact, the second helical ramp 17 does not extend along this second section 12, and the indexing means 21 of the sleeve 20 therefore ceases to be driven in motion. The indexing means 21 of the sheath 20 typically has a maximum dimension adapted so that it is not driven by the first helical ramp. The cup 30 then moves in the sheath 20, which typically comprises a groove coinciding with the groove of the inner guide 50 to allow movement of the indexing means 31 of the cup 30. The cup 30 is then driven in movement along the second section 12 of the tubular body 10, until reaching the end of the sheath 20 coming out of the container 1, as illustrated in FIG. 3. The product stick 40, typically the lipstick grape, then leaves the container 1 and can be used.

In order to retract the product stick 40 into the container 1, the user rotates the tubular body 10 by means of its ring 15 in a second direction of rotation opposite to said first direction of rotation, which will be called a direction of rotation. closing.

The rotation of the tubular body 10 in the closing direction causes a displacement of the cup 30 so as to return it into the sheath 20. The sheath 20 remains stationary while the cup 30 is moved because of the guidance of its indexing means 31 according to the second section 12 of the tubular body 10. Once the indexing means 31 of the cup 30 reaches the first section 11 of the tubular body 10, the latter continues its movement along the first helical ramp 16 to the proximal end 13 of the tubular body 10, and the displacement of the cup 30 resulting therefrom causes the joint 20 to move together. As an example, in the embodiment shown, the indexing means 31 of the cup 30 is a sliding finger in a groove formed in the sheath 20. When the indexing means 31 of the cup 30 reaches the first section 11 of the tubular body 10, it also comes into abutment at one end. tee of said groove of the sheath 20, and thus also drives it in motion.

Figures 5 and 6 illustrate a sectional view of the sheath 20, the cup 30 and the inner guide 50 in the configuration of Figure 2 presented above. FIG. 6 shows a detailed view of part of FIG. 5. These figures more specifically illustrate the indexing means 21 and 31 of the sheath 20 and of the cup 30, as well as the grooves of the sheath 20 and of the internal guide 50. which guide the displacement of these indexing means 21 and 31. Also in this figure 5 is the proximal end 23 of the sheath 20 which is the end of the sleeve opposite the opening 63 of the container 1, and its distal end 14 which is the end of the sheath 20 adapted to exit the container 1 via its opening 63 as previously described.

In the embodiment shown, the indexing means 31 of the cup 30 is a cylindrical lug. This lug 31 moves according to the groove 22 of the sheath 20, which extends along the length of said sheath 20, to abut against one or the other end of said groove 22. The indexing means 21 of the sheath 20 is a hollow half-cylinder whose internal diameter is substantially equal to or slightly greater than the external diameter of the lug 31. This indexing means 21 is here disposed at the end of the groove 22 of the sheath close to its proximal end 23, and moves along the groove 52 of the inner guide 50. When the lug 31 of the cup 30 abuts against the end of the groove 22 of the sheath 20 near its proximal end 23, the displacement of the lug 31 thus causes the joint displacement of the cup 30 and sheath 20.

These FIGS. 5 and 6 further illustrate a groove 32 provided in the cup 30. In the embodiment shown, the cup 30 comprises two grooves 32 arranged at substantially 180 ° to one another on the periphery of the cup 30 These two grooves 32 have substantially a shape of 2, and extend over the entire thickness of the cup 30. The grooves 32 are arranged so as to partially surround the lugs 31 of the cup 30, which are then arranged on a tab 33 defined by the U-shape of the grooves 32. These grooves 32 facilitate assembly of the various elements together, including the insertion of the cup 30 in the sleeve 20; the lugs 33 on which the lugs 31 are arranged may be slightly bent in order to accommodate the lugs 31 in the groove 22 of the sheath 20.

Figure 7 shows an external view of a container 1 as presented above, wherein the valves 64 are held open by the sleeve 20, and the product stick 40 is released.

This figure illustrates the ring 15 of the tubular body 10 which is the only part of the container 1 to be directly manipulated by the user in order to open or close the container 1.

FIG. 8 shows a variant of the container shown in FIG. 7, comprising a single valve 64 for closing the opening 63 of the container 1.

The container 1 according to the invention thus has several advantages. 10 It is easy to use; the user can indeed handle it with one hand, and has a single movement to open or close it. This movement consisting of a rotation of the ring 15 of the tubular body 10, it is also intuitive and easy to achieve. The positioning of the ring 15 making it possible to open and close the container at an intermediate position of the container 1, that is to say between the gripping portion 61 and the cap 62 of the covering 60 makes it possible to both easy handling of the container 1, and to prevent the valve or valves 64 are rotated during the opening or closing of the container.

In addition, the product stick 40, typically the lipstick raisin does not come into contact with the valve or valves 64, insofar as it is the sleeve 20 which releases the opening 63 of the container 1 previously 25 at the exit of the product stick 40.

The structure of the container is also simplified compared to known containers; particularly with regard to the elastic return means of the valve or valves closing the opening 63 of the container 30 1.

Furthermore, the indexing means 21 and 31 of the sleeve 20 and the cup 30 move in the same path, which allows to have a significant accuracy on the indexing of these elements, and avoids an offset the movement of the sheath and the movement of the cup, to avoid contact between the grapes and the valve when opening / closing the container.

The product stick 40 is thus totally protected with respect to the contact with the valve (s) 64 of the container 1.
