Vial with neck for a liquid product

1. A bottle with neck for a liquid product having an external shape, comprising:

a glass piece, said glass piece having an annular assembly surface;

a rigid piece having an annular assembly surface;

a neck formed on the glass piece or rigid piece;

an adhesive providing a fluidtight seal between the annular assembly surface of the glass piece and the annular assembly surface or the rigid piece, thereby ensuring the fluidtight seal,

the glass piece, rigid piece, and neck giving the bottle its external shape;

a glue trap on the annular assembly surface of either the glass piece or the rigid piece or is divided between the glass piece and the rigid piece, the glue trap having a filling groove for depositing adhesive, at least one bonding surface, and at least one overflow groove, the filling groove, the bonding surface, and the overflow groove being substantially concentric, and the filling groove and the overflow groove being narrower than the width of the annular assembly surface of both the glass piece and the rigid piece, wherein the filling groove and the overflow groove are independently depressed from the annular assembly surface of the glass piece or the rigid piece and away from the edges thereof.

2. The bottle according to claim 1 , wherein the glass piece comprises a side wall, an annular edge of which forms an opening, the annular assembly surface being located on the annular edge forming the opening.

3. The bottle according to claim 2 , wherein the annular edge forming the opening has a shoulder in which is formed the annular assembly surface.

4. The bottle according to claim 1 , wherein the adhesive is a silicone adhesive.

5. The bottle according to claim 1 , wherein the annular assembly surface of the glass piece faces the annular assembly surface of the rigid piece, and the adhesive is placed therebetween.

6. The bottle according to claim 5 , wherein the rigid piece comprises an annular flange on which is provided the annular assembly surface of the rigid piece.

7. The bottle according to claim 1 , wherein the annular assembly surfaces of the glass piece and rigid piece are oriented collinearly to a direction of assembly of the glass piece with the rigid piece.

8. The bottle according to claim 1 , wherein the annular assembly surfaces of the glass piece and the rigid piece are oriented in a direction forming an acute angle that is substantially non-zero with a direction of assembly of the glass piece with the rigid piece.

9. The bottle according to claim 8 , wherein the acute angle is substantially equal to 90°.

10. The bottle of claim 1 , wherein the filling groove and the overflow groove are provided on and away from the edge of the annular assembly surface of the glass piece.

11. The bottle of claim 1 , wherein the filling groove and the overflow groove are provided on and away from the edge of the annular assembly surface of the rigid piece.

12. The bottle of claim 1 , wherein the filling groove is provided on and away from the edge of the annular assembly surface of either one of the glass piece and rigid piece and the overflow groove is provided on and away from the annular assembly surface of the other one of the glass piece and rigid piece.

13. A packaging device for a liquid product, comprising a bottle and a dispenser of liquid product, wherein the bottle is a bottle with a neck for a liquid product having an external shape and comprising:

a glass piece, said glass piece having an annular assembly surface;

a rigid piece having an annular assembly surface;

a neck formed on the glass piece or rigid piece;

an adhesive providing a fluidtight seal between the annular assembly surface of the glass piece and the annular assembly surface of the rigid piece, thereby ensuring the fluidtight seal,

the glass piece, rigid piece, and neck giving the bottle its external shape; and

a glue trap on the annular assembly surface of either the glass piece or the rigid piece or is divided between the glass piece and the rigid piece, the glue trap having a filling groove for depositing adhesive, at least one bonding surface, and at least one overflow groove, the filling groove, the bonding surface, and the overflow groove being substantially concentric, and the filling groove and the overflow groove being narrower than the width of the annular assembly surfaces of both the glass piece and the rigid piece, wherein the filling groove and the overflow groove are independently depressed from the annular assembly surface of the glass piece or the rigid piece and away from the edges thereof.

14. A bottle with a neck for a liquid product having an external shape, comprising:

a glass piece, said glass piece having an annular assembly surface;

a rigid piece having an annular assembly surface;

a neck formed on the glass piece or rigid piece;

an adhesive providing a fluidtight seal between the annular assembly surface of the glass piece and a sealing annular strip, the sealing annular strip being securely connected to the annular assembly surface of the rigid piece, thereby ensuring the fluidtight seal;

wherein the sealing annular strip comprises two concentric annular portions, a first sealing portion sealed to the annular assembly surface of the glass piece and a second sealing portion sealed to the annular assembly surface of the rigid piece, the annular assembly surfaces of the glass piece and the rigid piece being substantially adjacent, substantially in the same plane and adhering to the same side of the sealing annular strip,

the glass piece, rigid piece, and neck giving the bottle its external shape.
