• the lower peripheral skirt 86 has reliefs that are complementary to the ones of a corresponding peripheral wall 87 of the covering support 85 for snap-fastening them.
• the support piece 10 comprises a circumferential lip 88 extending from the upper end of the support piece 10 on the opposite side of the outer edge 33.
• this circumferential lip 88 covers the annular location 34 above the mesh 6 and may act as an abutment. In this zone, the mesh 6 is thus sandwiched between the circumferential lip 88 and the stretching member 16 being the upper end of the internal peripheral skirt 4 of the cup member 2.
• the stretching member 16 is part of the covering part 75 that comprises a neck 90 of the device 1, having a wall 91 extending under the neck 90 and coupled to the cup member 2 by snap-fastening.
• the covering part 75 also participates to the immobilization of the support piece 10.
• the upper end of the cup member 2 extends between this wall 91 and the external peripheral skirt 25.
• the latter is part of the covering part 75, extending under the neck 90 and being in contact at the location 20 with the support piece 10 so as to immobilize it by friction.
• the external peripheral skirt 25 is linked by the wall 27 to the internal peripheral skirt 4 which is part of the covering part 75 too and comprises at an upper end the stretching member 16.
• Figures 20 to 23 illustrate an embodiment wherein the internal peripheral skirt 4 has a varying height.
• the stretching member 16 is formed by the upper end of the internal peripheral skirt 4 so that the shape of the inner zone 37 of the mesh 4 is not flat after assembling.
• the peripheral fixing zone 12 is neither flat, having a shape similar to the one of the upper end of the internal peripheral skirt 4. Otherwise the cup member 2 and the support piece 10 are quite similar to the ones shown in figures 1 to 4.
• one of the support piece 10 and the cup member 2 in this example the support piece 10, comprises a first partition wall 100
• the other of the support piece 10 and the cup member 2 in this example the cup member 2 comprises two second partition walls 101 and 102 surrounding the first separation wall 100 such that the mesh 6 is enclosed between the first partition wall 100 and each of the two second partition walls 101 and 102.
• the mesh 6 is stretched by the stretching member 16 at the periphery and also at the partition walls 100, 101 and 102, as shown in figure 26.
• the second partition walls 101 and 102 provides two compartments of product within the cup member 2, even if there is one mesh 6, one support piece 10 and one cup member 2.
• the invention is not limited to the embodiments shown. There may be more than two compartments of product within the cup member 2.
