Definitions

  • the present invention relates to a pouring closure with a pouring tube that can be inserted into a container opening and at least partially protrudes or pulls out of the container opening.
  • a holder can also be provided for fixing the tube in the container opening in the protruding and possibly also in the inserted position.
  • pouring closures are known in various forms.
  • such a tube is inserted directly into a container neck and fixed in it by means of locking cams or the like.
  • the tube can also have a plurality of locking points, so that it can be fixed in positions pulled out of the container neck to different degrees.
  • an additional holding element in the form of a snap or screw ring is provided as a holder for fixing the tube in the container opening.
  • Securing devices such as a circumferential tear tape and / or a screw cap for the closure can also be provided on this.
  • pouring closures have already been proposed which provide ventilation devices in addition to the pouring tube. These consist of an additional ventilation tube attached next to or in the tube, which is guided, for example, in the interior of the container so that its inner opening is not exposed to liquid.
  • two mutually concentric pipes are provided, the inner pipe serving as a pouring pipe and the annular space between the inner and outer pipes serving as a ventilation pipe.
  • the present invention has for its object to design a pouring closure with the features mentioned so that on the one hand it allows a proper pouring of liquid from the container on which it is located without strong fluctuations in the liquid jet, but on the other hand also a relative simple and easy to manufacture shape.
  • the tube of the closure provided for pouring in its pouring position, in which it protrudes from the container opening, extends at least partially into the interior of the container, in which the outside of the tube is also acted upon by the liquid to be poured out, in that In the area of the pipe end inside the container, a cross-sectional constriction is provided in which the free flow cross-section of the pipe is minimal and that between this cross-sectional constriction and the pouring opening of the pipe at least one opening is provided in the pipe side wall, which is also still within the range of the pipe side wall, which is inside the container.
  • the closure is rotated so that the opening lies in the area of the pipe segment at the top when pouring.
  • This can be achieved, for example, in that in the case of containers which are usually held in a certain position during pouring, for example because they have a handle on the lid, the tube is inserted into the container opening in a fixed manner against rotational movements.
  • the tube is already oriented when the closure is inserted into the container opening in such a way that it lies in the tube segment lying at the top during pouring.
  • a marking can also be provided on the protruding end of the pouring tube or of a part connected in a rotationally fixed manner to this pouring tube, the position of which determines the position of the opening in the tube side wall in the interior of the container.
  • Such an embodiment would be particularly useful with such containers, the orientation of which is not clearly defined when pouring out, so that the user himself can turn the closure on the basis of the marking in such a way that the opening mentioned in the tube side wall lies in the tube segment which is at the top when pouring out.
  • an embodiment of the invention is preferred in which a plurality of openings are distributed along the circumference of the tube side wall in the interior of the container.
  • a plurality of openings are distributed along the circumference of the tube side wall in the interior of the container.
  • an embodiment of the invention is the sum of the free cross sections of the constriction and the openings in the pipe side wall smaller than the free pipe cross section between the constriction and the outlet opening of the pipe.
  • the end of the pipe protruding towards the center of the pipe is provided, by which the constriction is formed.
  • a circumferential flange or ring which projects into the inside of the pipe is simply provided at this pipe end and narrows the pipe cross section accordingly.
  • the narrowing alone is not sufficient to prevent the intermittent penetration of larger air bubbles, which makes the liquid jet unstable. Rather, it is crucial that there is at least one additional opening between the constriction and pouring opening of the pipe in the pipe side wall, through which air bubbles can penetrate, but which do not impair the main flow of the liquid passing through the constriction.
  • the cross section of an opening in the pipe side wall through which air bubbles enter is smaller than the free pipe cross section in the region of the constriction.
  • the openings in the tube sidewall are in the form of elongated slots aligned along the tube axis.
  • the tube can be provided as a so-called telescopic tube, ie it can be inserted into the container opening so that its front end protrudes only slightly or not at all over the container opening or a corresponding container neck, and can be pulled out of the container opening for use so that it protrudes relatively far out of the container opening, which facilitates pouring in inaccessible places or into smaller openings.
  • a tube is expediently provided with locking cams and / or stops for engagement with suitable counterparts on the tube holder.
  • the interior of the container or the interior of the container is the entire connected and enclosed Volume outside the tube includes.
  • the interior of the container also includes, for example, the space between a bellows and the wall area of the tube which has the opening or openings, even if the bellows is already clearly above the actual container opening or a container neck in the pulled-out position.
  • this intermediate space is also directly related to the inner volume of the container and is acted upon by liquid when the container is tilted and when the liquid is poured out, so that it can also be counted towards the inside of the container in the sense of the present invention.
  • the tube holder has a retaining ring which lies closely against the tube and acts as a wiper ring when the tube is pulled out.
  • the counterparts to the locking cams or stops on the tube can also be designed as a retaining ring.
  • the screw cap and the tube holder are designed such that the screw cap can be unscrewed from the tube holder regardless of its connection to the tube and can thus be removed from it, thereby taking the tube into the extended position.
  • a container opening 6 is formed by a container neck 15.
  • An annular closure holder 7 is placed on the container neck 15.
  • This closure holder 7 is U-shaped in cross section and thus encompasses the container neck 15 from the inside and outside.
  • anti-rotation devices can be arranged between the closure holder and the container neck.
  • projections and stops 10, 10 ' are provided for engagement with locking cams 8 and / or stops 9, 9' on the outer wall of the telescopic tube 1.
  • a screw cap 11 which is screwed onto an external thread of the closure holder 7 and additionally has a tear-off tape 16 on its lower edge, which has to be torn off when the container is opened, so that the closure as Guarantee lock can be used.
  • the telescopic tube has stops 9 ′ on its outside in the upper or front area, which can be formed in a ring-shaped manner and rest on corresponding counterparts 10 in the inserted position of the tube 1.
  • the constriction 2 is at the rear end of the tube formed by fins 4 inclined conically from the edge of the pipe end to the pipe center.
  • the openings 3 have the shape of elongated, parallel to the tube axis aligned slots that are evenly spaced along the circumference of the tube side wall 13.
  • the openings have the shape of elongated ovals or the shape of slots with rounded ends.
  • the constriction is formed by a circumferential annular flange 17 which starts at the pipe end and projects inwards.
  • the embodiment in FIG. 4 is identical to the embodiment shown in FIG. 3 except for the shape of this ring flange, but the ring flange 17 does not run perpendicular to the tube axis, but inclines toward the tube axis, forming a conical surface.
  • the respective constriction can be formed by a cap that can be placed on the pipe end with corresponding projections directed toward the pipe center.
  • Figures 5 and 6 represent a further embodiment in which the tube is not slidably telescopically inserted into a container neck, but in which the tube is part of a bellows seal, the bellows 14 outside of the tube 1 above or before the constriction 2 and the openings 3 in the tube side wall 13 attaches.
  • FIG. 5 shows the bellows closure in the inserted position, while the bellows closure is shown in FIG. 6 with the bellows turned out.
  • the space between the folded bellows 14 and the tube side wall 13 in the area and above the openings 3 is also considered to be part of the container interior 12 in this case.
  • the counterpart 10 for the cams 8 and 9 'on the tube 1 is designed as a retaining ring lying closely on the tube outer wall, so that it acts as a wiping element for the liquid, which can be on the outside of the tube.
  • the screw cap 11 can be unscrewed from the pipe holder 7, however Extensions 19 or a circumferential ring web engage behind an upper cam 9 "on the outer tube wall. In this way, when the cover 11 is moved upwards, the tube 1 becomes upward via the engagement between the cam-like projection 9" and the (possibly annular) extension 19 is taken away. By pulling up the screw cap 11, the tube 1 is then taken upwards and brought into the pulled-out position, the cap 11 only being pulled off the tube 1 in this position, since this then bears against the counterparts 10 'with the stops 9.
