Definitions

  • the invention relates to a pouring spout for fitting in the outlet opening of a container, e.g. a bottle or the like, and comprising a tubular portion having a downwardly facing inlet opening and an upwardly facing outlet opening with an annular edge and a collar portion on said tubular portion for abutment on a container edge.
  • pouring spouts are used for mounting in container openings where they serve to provide spill-proof dis ⁇ pensation of liquid from the container.
  • the pouring spout acts as a drip catcher.
  • a pouring spout of the above-mentioned type is described in e.g. German patent publication No. 1,944,012. At its outlet opening the thus known pouring spout is provided with a flat edge and consequently it has been known not always to ensure the desired spill-proof dispensation of liquid.
  • a corresponding pouring spout is also known which is provided with a rounded portion on the inside of the tubular portion. This embodiment does not ensure spill- proof dispensation, either.
  • US patent No. 4,222,504 discloses a pouring spout which is provided with an annular edge at its outlet opening.
  • the pouring spout is provided with a conical portion which expands towards the outlet opening. This means that by use of such pouring spout and when dispensation is discontinued there is a high risk of spilling as the container, e.g.
  • DK patent application No. 2297/90 discloses devices comprising a rounded film disc and intended for fitting into a bottle neck. Such device may only be used in connection with a bottle and only for the dispensation at a determined position of the device. Moreover the device which is secured by means of its intrinsic resiliency requires that the bottle neck has a smooth and uniform inner surface in order for the disc to abut thereon. Spill- proof dispensation is therefore not always ensured, bottles often having rough and non-uniform designs. In such cases the liquid often trickles from between the film disc and the bottle neck.
  • the invention is based on the discovery that in order to ensure the spill-proof dispensation, the surface tension must be ruptured abruptly without any possibility of drops sticking to the outside of the pouring spout and from there finding its way below.
  • the pouring spout is well suitable for fitting to a bottle but other applications are also possible. Exemplary applications include plastics cans, cardbord packagings or the like.
  • the pouring spout may conveniently be provided with an inlet portion having an internal cross sectional area which is larger than the internal cross sectional area of the tubular portion at the outlet. Thereby undisturbed flow in and about the inlet is ensured.
  • An alternative embodiment of the pouring spout according to the invention is provided with through-going holes in the downwardly facing portion of the tube. These holes contri ⁇ bute to the filtration of impurities contained in the container from the liquid when the latter passes into the tubular portions and may, if the pouring spout is used in connection with a wine bottle, moreover contribute to efficient oxidation of the wine during dispensation.
  • Fig. 1 is a longitudinal sectional view of an em- 5 bodiment of the pouring spout according to the invention
  • Fig. 2 shows an alternative embodiment of a pouring spout according to the invention seen sidewise, 10 and
  • Fig. 3 shows a further embodiment of the pouring spout according to the invention seen sidewise.
  • the pouring spout is formed of a tubular portion 1 which, in the area around the outlet opening 3 on the inside 6, extends substantially parallel with the center line of the tubular portion 3 and on the outside 7 is inclined towards the center line towards the outlet
  • the pouring spout is provided with an expansion which results from the tubular portion on the inside extending in an inclined manner away from the center line, whereas the tubular portion on the outside extends sub-
  • the pouring spout is provided with a collar 4 which in the mounted state of the pouring spout
  • Fig. 2 shows an alternative embodiment of the pouring spout 35 according to the invention wherein, as distinguished from the pouring spout shown in Fig. 1, only one sealing flange 8 is provided and wherein guides 9 are arranged, too.
  • Fig. 3 shows a third embodiment of the pouring spout according to the invention where the tubular portion 1 is provided with through-going holes 10 between the inside 6 and the outside 7.
  • the upward portion of the pouring spout is of frustoconical shape on the outside.
  • the angle between the center line and a random generatrix on the inclined outer surface is an acute angle.
  • containers such as bottles
  • standards prescribe certain outlet diameters but allow deviations within certain tolerances.
  • Such containers and packagings of e.g. glass may moreover have rough and non-uniform surfaces.
  • the pouring spout may be designed with one or more annular flexible sealing flanges and it may moreover be provided with guides positioned along the periphery of the tubular portion.
  • the guides serve to guide and centra ⁇ lize the pouring spout when mounting the latter in a container.
  • the pouring spout may be designed with through-going holes in the tubular portion.
  • the holes serve to filter and oxidize the container contents, e.g. wine in a bottle.
  • the holes are preferably in the shape of circular, through- going holes with a diameter of more than 0.5 mm.
  • the circular holes have a diameter of about 1 mm.
  • a wine bottle sediments or other particles, if any, will be filtered off the wine by dispensation.
  • the pouring spout will contribute to efficient oxidization of the wine as bubbles of atmospheric air which enter through the pouring spout during dispensation because of the holes will divide into smaller bubbles and rise through the holes. During division the bubbles have achieved a larger overall surface area which results in an efficient oxidiza ⁇ tion. Decantation of the wine to obtain oxidization is therefore no longer necessary.
  • the pouring spout according to the latter embodiment is conveniently designed with at least 100 holes, and it has been shown that a particularly favourable effect with regard to the oxidization occurs when the pouring spout has from 300 to 400 holes.
  • the pouring spout is made of plastics and may e.g. be produced in an injection moulding process.
  • An embodiment where the pouring spout is made of a metallic material is also possible.

Abstract

L'invention concerne un bec verseur qui s'adapte sur l'ouverture d'un contenant tel qu'un goulot de bouteille et est constitué d'une partie tubulaire (1) présentant un orifice d'admission (2), un orifice de sortie (3) et un col (4) destiné à buter contre le rebord d'un contenant. Au niveau de l'orifice de sortie (2) et sur l'extérieur la partie tubulaire (1) est conçue pour être oblique vers sa ligne médiane et vers l'orifice de sortie alors que l'intérieur de ladite partie tubulaire (1) s'étend pratiquement parallèlement à cette même ligne. Au niveau de son orifice d'admission et sur l'intérieur (6), ledit bec verseur peut être incliné vers la ligne médiane de la partie tubulaire ainsi que vers l'orifice de sortie, et peut présenter des orifices traversant (10) la partie tubulaire (1), entre l'orifice d'admission (2) et le col (4) de celui-ci.
