A spill-proof pouring device for fixing inside the neck of a bottle includes a skirt sealing to the inside of the neck on its outer surface and having an internal channel. An upper flared portion of the skirt protrudes beyond the lip of the neck, and is formed of a flexible material. The flared portion joins the skirt at a point of union of reduced thickness to permit flexing action by the protruding portion.

1. A drip-proof pouring device (1) for use inside of a neck of a bottle, comprising:a skirt (2) forming an internal channel and having an external surface, a hermetic sealing system disposed on the external surface, the hermetic sealing system comprising at least one flexible peripheral ring forming a ribbing, an upper flared portion (21) disposed at a top end (22) of the skirt and having a protruding portion (210) exiting above a lip (60) of the neck at a height (H) when the pouring device is disposed inside the neck of the bottle, wherein the protruding portion (210) is flexible and includes a thickness so it can flex and regain its original uncompressed position when the pressure is released, wherein a point of union between the top end (22) of the skirt and the flared portion is reduced in thickness to function as a hinge and to permit the multiple flexion action by the protruding portion, wherein an external surface of the top end (22) of the skirt (2) has an external rim on its outside surface (28) to form a block system or shoulder to fix the pouring device position in the neck, the external rim in question (28) is pressed against the internal rim of the lip (60) so that it blocks the pouring device (1) at an established level inside the neck (6), and permits the application of the flexible protruding portion (210) against the lip, and wherein the pouring device is composed of mold solid block piece. 2. Pouring device as claimed in claim 1, wherein the material is chosen from among thermoplastic polymers or copolymers suitable for moulding, such as PE, PP, PET, polybutene or metallocene.3. Pouring device as claimed in claim 1, wherein the material in question contains an elastomer such as polybutadiene.4. Pouring device as claimed in claim 1, wherein the hermetic fixing system is composed of at least two peripheral rows of ribbing (200) arranged parallel horizontally.5. Pouring device as described in claim 4 in which the external diameter of each peripheral ribbing (200) increases the further it is placed from the low end (23) of the skirt (12).6. Pouring device as described in claim 5 in which the hermetic fixing system (20) includes a rib, described as “low” (201) closest to the low end of the skirt (23) and positioned less than 10 mm from the low end so that the retained liquid does not exceed 1 cm3 when the vessel is empty and the neck is turned upside-down.7. Pouring device as claimed in claim 5, in which the external perimeter of at least one peripheral ribbing (200) is reduced in thickness (202).8. Pouring device as claimed in claim 1, in which the skirt includes a system for limiting the flow, composed of a partial sealing of the internal channel, in the form of a flat divider (24) perforated with openings (240).9. Pouring device as claimed in claim 1, in which the skirt (2) includes a low end (23) equipped with an internal divider (24) and internal rim (26) that retains a marble (27) to form a check valve to prevent unauthorised filling of the bottle or vessel (5) once its initial contents have been consumed.10. Pouring device as claimed in claim 1, composed of a moulded solid block made up of a single or several plastic materials.11. Pouring device as described in claim 10 composed of a single plastic material where the average thickness EF of the flexible protruding portion in question (210) is less than the thickness E, of the skirt (2).12. Pouring device as described in claim 11 in which the average thickness EF is less than 0.5 E.13. Pouring device as described in claim 10 in which the moulded solid block part that includes the skirt (2) and the upper flared portion (21) is composed of two different plastic materials; the more rigid plastic material forming the skirt (2) equipped with ribbing (200) the more flexible plastic material forming the upper flared portion (21).14. Sealing cap (3) composed of:a) a hermetic sealing system; b) a pouring device (1) as described in claim 1; and c) a temporary adherence system between the pouring device in question (I) the sealing cap in question (3) conceived so that the pouring device (1) that adheres initially to the cap (3) then adheres to the neck (6) of the vessel in question (5) irreversibly during the application of the cap on the vessel. 15. Sealing cap as described in claim 14 in which the hermetic sealing system is chosen between an added seal (8) or an insert (4) attached to the inside of the cap, either by a blocking projection (30) or by a layer of adhesive, or by force fit.16. Sealing cap as described in claim 14 in which the hermetic sealing system is composed of a plastic insert (4) normally equipped with a circular rim (40).17. Sealing cap as described in claim 16 in which the circular rim in question (40) adheres to the pouring device (1) normally with the inside of the skirt in question (2) to form the temporary adherence system.18. Sealing cap as claimed in claim 16, in which the circular rim (40) adheres to the outside of the lip (60) of the neck (6) to form the hermetic sealing system in question.19. Sealing cap as claimed in claim 16, in which the temporary adherence system is formed by the interaction of the peripheral perimeters (25, 41) by snap-on or click-fit action on the inside of the skirt (2) and the outside of the circular rim in question (40) respectively.20. Sealing cap as claimed in claim 14, including the systems to guarantee that the contents remain intact, and/or the initial easy opening with the inclusion of a perforated or easily broken line.
