Abstract

Claims (14)

1. Device ( 10 ) for packaging at least one product and dispensing at least said product on a surface and comprising at least one container ( 12 ) delimiting a product cavity ( 22 ) containing said at least one product and a dispensing member ( 14 ) mounted on said at least one container ( 12 ) and having a first dispensing orifice ( 24 b ) in flow communication with the product cavity ( 22 ), said container ( 12 ) having a neck ( 18 ) allowing access to the product cavity ( 22 ), said dispensing member ( 14 ) comprising a dispensing duct ( 24 ) in flow communication with the product cavity ( 22 ), an assembly skirt ( 30 ) radially surrounding said dispensing duct ( 24 ) and an annular sealing lip ( 32 ) radially disposed between said dispensing duct ( 24 ) and said assembly skirt ( 30 ), said annular sealing lip ( 32 ) bearing radially against a sealing portion ( 18 c ) of the neck ( 18 ) of the container ( 12 ), characterized in that said sealing portion ( 18 c ) is located axially away from an opened end of the neck ( 18 ), wherein the sealing portion ( 18 c ) of the neck ( 18 ) is a portion extending radially inwardly from an inner surface of an upper portion ( 18 d ) of the neck ( 18 ) and wherein the upper portion ( 18 d ) of the neck ( 18 ) of the lower container ( 12 ) has an inner diameter that is larger than an outer diameter of the annular sealing lip ( 32 ) of the upper container ( 14 ).

2. Device according to claim 1 , wherein the annular sealing lip ( 32 ) of the dispensing member ( 14 ) bears radially against an inner surface of the sealing portion ( 18 c ) of the neck.

3. Device according to claim 1 , wherein the inner diameter of the sealing portion ( 18 c ) of the neck ( 18 ) is smaller than the outer diameter of the sealing lip ( 32 ) of the dispensing member ( 14 ).

4. Device according to claim 1 , wherein the sealing portion ( 18 c ) of the neck ( 18 ) is configured to be elastically deformed when inserting the dispensing duct ( 24 ) of the dispensing member ( 14 ) in the neck ( 18 ) of the at least one container ( 12 ).

5. Device according to claim 1 , wherein the sealing portion ( 18 c ) of the neck ( 18 ) has a width thinner than the width of the opened end of the neck ( 18 ).

6. Device according to claim 1 , wherein the sealing portion ( 18 c ) of the neck ( 18 ) has a C-shape in cross section.

7. Device according to claim 1 , wherein the assembly skirt ( 30 ) radially surrounds the neck ( 18 ) of the container and cooperates with said neck ( 18 ) to axially secure the dispensing member ( 14 ) on the container ( 12 ).

8. Device according to claim 7 , wherein the assembly skirt ( 30 ) is provided on its radially inner surface with an annular bead ( 30 a ) cooperating with an annular groove ( 18 b ) of the container ( 12 ) by snap-fit attachment, such that the dispensing member ( 14 ) is held axially relative to the container ( 12 ), while allowing a rotating movement one relative to the other.

9. Device according to claim 8 , wherein the annular groove ( 18 b ) of the container ( 12 ) is axially arranged between two outer annular shoulders ( 18 a ), and wherein the sealing portion ( 18 c ) of the neck ( 18 ) is axially located above the upper the annular shoulder ( 18 a ).

10. Device ( 10 ) according to claim 1 , wherein the dispensing member ( 14 ) defines a second container delimiting a second product cavity ( 24 a ) containing a second product (B) and separated from the first product cavity ( 22 ), said containers ( 12 , 14 ) being capable of rotating one relative to the other without moving axially.

11. Device ( 10 ) according to claim 10 , wherein said device ( 10 ) further comprises a temporary closing member ( 50 ) configured to close an opened end ( 28 ) of the second container ( 14 ) before the first use, and comprising a cylindrical skirt ( 52 ) surrounding said opened end ( 28 ) and a plug ( 54 ) connected to said cylindrical skirt ( 52 ), said cylindrical skirt ( 52 ) being provided, on its inner cylindrical surface, with inner threads ( 52 a ) cooperating with outer threads ( 28 a ) provided on the upper container ( 14 ) and on its outer cylindrical surface, with first anti-rotation means ( 52 b ) cooperating with second anti-rotation means ( 18 e ) provided on the lower container ( 12 ) for preventing rotation between the closing member ( 50 ) and the lower container ( 12 ), the closing member ( 50 ) being deprived from any axially retaining members with both containers ( 12 , 14 ), such that when the upper container ( 14 ) is rotated in a first rotation direction (F 1 ), the closing member ( 50 ) translates downwardly until falling into the first product cavity ( 22 ).

12. Device ( 10 ) according to claim 11 , wherein the upper surface of the plug ( 54 ) comprises a first annular sealing lip ( 54 a ) extending axially towards the second container ( 14 ) and having an outer diameter substantially equal to the inner diameter of the opened end ( 28 ) of the dispensing duct ( 24 ) and a second sealing lip ( 54 b ) extending axially in an annular groove ( 28 b ) provided at the end of the lower opened end ( 28 ).

13. Device ( 10 ) according to claim 12 , wherein the second sealing lip ( 54 b ) is annular.

14. Device ( 10 ) according to claim 12 , wherein the second sealing lip ( 54 b ) has an axial length smaller than the axial length of the first sealing lip ( 54 a ).
