Abstract
The invention relates to a device for packaging a cosmetic product (P) in solid form and applying it to the skin, having a longitudinal axis X, comprising: a sleeve (70) containing the cosmetic product (P), an elevator means (50) able to support the cosmetic product (P) at a current position in the sleeve and to axially move the cosmetic product along the axis X to make it emerge from the sleeve (70) bypassing through the orifices (77), a means (60) for manually actuating the elevator, a means (80) for partial covering of the outlet of the sleeve (70) comprising a vault (71) formed solely of an elastically deformable material.
Claims14
Device for packaging a cosmetic product (P) in solid form and applying it to the skin, having a longitudinal axis X, comprising:
- a sleeve (70) containing the cosmetic product (P),
- an elevator means (50) able to support the cosmetic product (P) at a current position in the sleeve (70) and to axially move the cosmetic product along the axis X to make it emerge from the sleeve (70) by passing through the orifices (77),
- a means (60) for manually actuating the elevator,
- a means (80) for partial covering of the outlet of the sleeve (70) comprising:
- a vault (71) made of a first elastically deformable material perforated by through-orifices (77), and
- a means (72) for supporting the vault (71) made of a second material,
- the vault (71) comprising an outer surface able to be brought into contact with the skin and an inner surface able to be brought into contact with the solid cosmetic product (P) before it passes through the orifices (77),
- characterized in that the vault (71) and the means (72) for supporting the vault (71) are configured so that more than 60% of the inner surface of the vault (71) with respect to its total surface is able to come into contact with the solid cosmetic product before it passes through the orifices, preferably more than 75%, more advantageously more than 95% and more advantageously still 100%.
Device according to either one of the preceding claims, characterized in that the first material is made of an elastomer.
Device according to any one of the preceding claims, characterized in that the second material is able to flex elastically during the application of the product (P) to the skin.
Device according to any one of the preceding claims, characterized in that the first and second materials are firmly attached to each other by bi-injection moulding.
Device according to any one of the preceding claims, characterized in that the outer surface area of the elastically deformable material represents more than 50%, preferably more than 75%, and more preferably still more than 95% of the surface area of the covering means able to come into contact with the skin.
Device according to any one of the preceding claims, characterized in that the vault (71) has an outward deflection value, under the application of a 500 gram load, ranging from 0.3 millimetre to 3 millimetres, preferably from 0.5 millimetre to 2.5 millimetres, and more preferably from 0.8 millimetre to 2 millimetres.
Device according to any one of the preceding claims, characterized in that the vault (71) has an inward deflection value, under the application of a 500 gram load, ranging from 1.5 millimetres to 7 millimetres, preferably from 1 millimetre to 6 millimetres, and more preferably from 2 millimetres to 5.5 millimetres.
Device according to any one of the preceding claims, characterized in that the surface area of the orifices represents between 0.1% and 15% of the total surface area of the vault and preferably between 0.2% and 10% of the total surface area of the vault.
Device according to any one of the preceding claims, characterized in that the cosmetic composition has a hardness measured at 32° C. under a humidity of 40% ranging from 5 kPa to 150 kPa, and preferably ranging from 20 kPa to 100 kPa.
Device according to any one of the preceding claims, characterized in that the cosmetic composition comprises at least one deodorant or antiperspirant active agent.
Device according to any one of the preceding claims, characterized in that the cosmetic composition is anhydrous.
Device according to any one of the preceding claims, characterized in that the cosmetic composition comprises at least one solid fatty substance.
