Definitions

  • TITLE Pour spout for facilitating pouring a liquid from a container
  • the invention relates to a pour spout for facilitating pouring a liquid from a container into a narrow opening, such as an opening of a tank, without spilling liquid.
  • a common approach for avoiding spilling is the use of a funnel.
  • a funnel entails several disadvantages. Liquid is still spilled quite easily over the edge of the funnel, the funnel can easily become dislodged, a funnel occupies relatively much space when not in use and when a funnel is used, an inner surface of the funnel wetted with liquid is relatively exposed, so that it can easily be touched by a user causing soiling of the user's hand.
  • Another approach for avoiding spilling which is commonly used when pouring fuel from a portable tank into a tank of for instance a car or a boat, is to pour the liquid via a pour spout which is coupled to an opening of the container from which liquid is to be poured.
  • a problem associated with the use of pour spouts is that venting of the container from which liquid is poured is needed for controlled and reasonably quick pouring of the liquid.
  • portable fuel tanks are typically provided with a venting opening at a distance from the opening to which the pour spout is to be coupled.
  • the added costs and complexity of such a venting opening which needs to be closed during storage and transport and needs to be opened prior to pouring, is a serious disadvantage.
  • It is also known to provide a venting conduit extending through the pour spout but such solutions add to the costs of the pour spout and generally do not provide effective venting during pouring.
  • KR200439003Y1 discloses a pour spout according to the pre-characterizing portion of the appended independent claim 1.
  • this object is achieved by providing a pour spout according to the appended independent claim 1.
  • Preferable embodiments of the invention are provided by the appended dependent claims 2-7.
  • venting channel interrupts the sealing surface or surfaces for allowing venting of the container through a passage between the coupling cap portion of the pour spout and a portion of the container facing the venting channel
  • the venting channel is achieved in a particularly simple manner by just leaving some material out inside the coupling cap portion.
  • an outside end of the venting channel is at a side of the coupling cap portion facing away from the pour conduit, i.e. at an extreme proximal end of the pour spout.
  • This extreme proximal end of the pour spout is vertically most elevated over the distal end of the pour channel during pouring with the conduit portion pointing generally downwards from the coupling cap portion. Due to this maximized difference in level between the outside end of the venting channel and the downstream end of the pour channel during pouring, venting reliably occurs via the venting channel, so that liquid does not tend to flow out via the venting channel.
  • the venting channel between the coupling cap portion and the container causes that the pour spout is not hermetically sealed at the interface to the coupling cap portion. This is no problem, because the pour spout is mounted instead of a hermetically sealing closure cap. If pouring has to be stopped before all of the contents of the container has been poured out, the pour spout can be removed from the container, which can then be re-closed hermetically using the closure cap.
  • pour spout which is known from the above- mentioned document KR200439003Y1 does not have a venting channel, let alone a venting channel according to the characterizing portion of the appended independent claim 1.
  • Fig. 1 is a side view of an example of a container provided with an example of a pour spout according to the invention
  • Fig. 2 is a side view of the pour spout shown in Fig. 1;
  • Fig. 3 is a cross-sectional side view of the pour spout shown in Figs. 1 and 2 and of a portion of a neck of a container;
  • Fig. 4 is a perspective view of the pour spout shown in Figs. 1-3;
  • Fig. 5 is a bottom view of the pour spout shown in Figs. 1-4;
  • Fig. 6 is a schematic side view of a container and pour spout of Fig. 1 in use for refilling an 'Adblue' tank of a passenger car.
  • a pour spout 1 according to the invention is shown.
  • the pour spout 1 is shown mounted on an example of a container 2, which can be provided as part of a kit including a container according to the invention.
  • a cut-away portion of a neck portion 12 of the container 2 extending around an opening 13 is also shown.
  • a kit also includes a closure cap (not shown) for hermetically closing off the container 2 for storage and transport.
  • the pour spout 1 and the container 2 can for instance be made from plastic material.
  • the container 2 can for instance be blow molded from an injection molded preform and the pour spout can for instance be completely injection molded or blow molded from an injection molded preform and subsequently be cut open at a free end.
  • the container and/or the pour spout such as glass or metal are conceivable as well.
  • the pour spout 1 has an elongate conduit portion 3 projecting from a coupling cap portion 4.
  • a pour channel 5 (see Figs. 3 and 5) extends in a longitudinal direction through the conduit portion 3.
  • the coupling cap portion 4 is arranged for coupling to a container 2 with the pour channel 5 in
  • First, second and third sealing surfaces 6, 7, 8 of the coupling cap portion 4 sealingly engage the container 2 around the opening 13 when the pour spout 1 has been mounted to the container 2.
  • a third one of the sealing surfaces 8 is a generally cylindrical internal surface provided with an internal thread 9 for engaging and sealing against a matching external thread 14 on the neck portion around the opening in the container.
  • alternative solutions for connecting the connecting cap portion to the container can be implemented as well, for instance a bayonet catch coupling, a coupling based on clamping engagement between the neck or opening of the container and coupling cap portion or a coupling with a snap member arranged for hooking behind a retention edge of the neck surrounding the opening of the container.
  • the coupling cap portion 4 has a rib 10 projecting axially in a direction away from the conduit portion 3 and extending around an area proximally adjacent to a proximal end 11 of the pour channel 5.
  • the first one of the sealing surfaces 6 is provided on an outer surface of the rib 10 and tapers from a largest diameter to a smaller at a free end rim 15 of the rib 10 for wedging against an interior surface 16 of the opening 13 of the container 2 to which the pour spout 1 is coupled, to reliably seal against that interior surface 16.
  • the second seal surface 7 is a generally planar, annular surface extending around the rib 10, for contacting a top end rim surface 17 of the neck 12 of the container 2. While in the present example three sealing surfaces are provided, also more or less sealing surfaces can be provided, e.g. one, two or four sealing surfaces. If a plurality of sealing surfaces is provided, these can be arranged in a coaxial of other configuration.
  • a venting channel 18 interrupts the sealing surfaces for allowing venting of the container 2 through a passage between the coupling cap portion 4 and a portion of the container 2, in this example the neck 12, facing the venting channel 18.
  • the venting channel 18 is provided in the form of a recess in the third sealing surface 8, which extends axially from a proximal end of the third sealing surface to a distal end of the third sealing surface. At the distal end of the third sealing surface, the venting channel 18 continues as a recess in the second sealing surface and an opening in the rib 10 interrupting the first sealing surface 6.
  • venting channel 18 provides a passage between the neck 12 of the container 2 and the coupling cap portion of the pour spout, which forms an interruption of the first, second and third sealing surfaces 6, 7 and 8 of the coupling cap portion 4, which allows air to pass along these surfaces into the container during pouring via the pour channel 5.
  • the venting channel 18 is obtained in a particularly simple manner by just leaving some material out inside the coupling cap portion 4. For instance in an injection mold this can be achieved in a simple manner by providing a protrusion on a core for molding the inside of the coupling cap portion 4.
  • venting channel 18 extends along a surface portion 8 of the coupling cap portion 4, an outside end of the venting channel 18 is at a side of the coupling cap portion 4 facing away from the pour conduit
  • this extreme proximal end of the pour spout 1 is vertically most elevated over the distal end of the pour channel 5 during pouring with the conduit portion 3 pointing generally downwards from the coupling cap portion. Due to this maximized difference in level between the outside end of the venting channel 18 and the downstream end of the pour channel 5 during pouring, venting reliably occurs via the venting channel 18, so that liquid does not tend to flow out via the venting channel 18.
  • the venting channel 18 between the coupling cap portion 4 and the container 2 causes that the pour spout 1 is not hermetically sealed at the interface to the container 2. This is no problem, because the pour spout 1 is mounted to the container 2 instead of a hermetically sealing closure cap. If pouring has to be stopped before all of the contents of the container 2 has been poured out, the pour spout 1 can be removed from the container 2, which can then be re-closed hermetically using the closure cap.
  • venting channel 18 is provided on one single lateral side of the cap portion 4 only. This counteracts leaking of liquid through a venting channel, while the container is vented through another venting channel, in particular if the conduit portion is held in a generally horizontal position.
  • the cap portion 4 has an internal end surface (in this example formed by the second sealing surface 7) having an outer circumferential portion extending in a plane 19 (see Fig. 3).
  • the longitudinal direction of the conduit portion 3 is oriented at an oblique angle a relative to the plane 19.
  • the lateral side where the venting channel 18 is provided is in a radial direction 20 (see Fig. 5) in which an angle a between the longitudinal direction of the conduit portion 3 and the plane 19 is smallest. This is advantageous for allowing easy pouring of the liquid into an opening in a flank of a vehicle 21 for filling up the 'Adblue' tank (Fig. 6).
  • the container 2 has a largest dimension in a direction perpendicular to the plane 19. Thus, the container 2 can be tilted very far, before it contacts the flank of the vehicle 21.
  • the conduit portion 3 of the spout 1 is preferably pointing in a direction deflected towards the car 21 compared to a direction perpendicular to the plane 19.
  • the pour spout 1' and the container 2' pass through intermediate positions in which the conduit portion 3' is oriented approximately horizontally, with the side of the coupling cap portion 4 where the angle a between the longitudinal direction of the conduit portion 3 and the plane 19 is smallest facing upwards.
  • venting channel 18 is then located only on the most upwardly facing side of the coupling cap portion 4, the liquid reaches the venting channel 18 only when the liquid starts to flow out of the pour channel 5 over the full cross-section of the pour channel 5. Accordingly, when the liquid reaches the venting channel 18, a partial vacuum already starts to be created inside the container 2. This in turn forces air in through the venting channel 18, so that spilling of liquid via the venting channel 18 is effectively counteracted. It is also noted that already when the conduit portion 3 is pointing in a generally horizontal direction, the venting channel 18 opens into the environment at a level above a distal (outlet) end of the pour channel 5.
  • venting channel 18 opens into the environment than at the distal (outlet) end of the pour channel 5.
  • venting air will enters the container 2 more easily via the venting channel 18 than via the pour channel 5, so when the container 2 and the pour spout 1 are is tilted in the most convenient way for pouring a liquid into an opening in a flank of a car, as liquid starts to flow out and reaches the venting channel, venting will (almost) immediately start via the venting channel 18 and no or only very little liquid will flow out via the venting channel.
  • the venting channel 18 has a first section in a cylindrical, radially inwardly facing surface 8 of the coupling cap portion 4 and a second section connecting to that first section extending radially in an end surface 7 extending inwardly from the cylindrical, radially inwardly facing surface 8.
  • the radial portion adds to the difference in levels between the outlet end of the pour channel 5 and of the outer end of the venting channel 18 when the conduit portion 3 is pointing in a generally horizontal direction
  • the axial portion of the venting channel adds to the difference in levels between the outlet end of the pour channel 5 and of the outer end of the venting channel 18 when the conduit portion 3 is pointing in a generally vertical downward direction.
  • the combined length of these first and second sections of the venting channel 18 cause to flow path to be long enough to avoid all or most of that liquid exits the venting channel 18 into the environment before venting via the venting channel 18 urges that liquid back into the container 2.
  • venting channel 18 breaks through the rib 10.
  • venting channel 18 is provided in the form of a continuous groove in the coupling cap portion 4, it can be formed in a simple low-cost manner, while it is reliably ensured that the venting channel is open even if large manufacturing tolerances are allowed for the container neck 12 and for the coupling cap portion 4.
  • the venting channel has a cross-sectional area of less than 40 mm 2 and more preferably less than 30 mm2 and more preferably less than 25 mm 2 .
  • the cross-section of the venting channel 18 should large enough to allow enough air to enter the container to allow smooth and quick pouring.
  • the venting channel preferably has a cross- sectional area of more than 4 mm 2 and more preferably more than 6 and more preferably more than 9 mm 2 .
  • the coupling cap portion 4 has a locally protruding portion on its exterior side that faces away from the venting channel 18.
  • This locally protruding portion provides the advantage that the cross-section of the venting channel 18 can be designed large enough to allow enough air to enter the container, without needing to thicken the complete coupling cap portion 4 for that purpose.
  • the locally protruding portion is extending both in a region facing away from the above-mentioned first section of the venting channel 18, and in a region facing away from the above-mentioned second section of the venting channel 18.
  • Alternative embodiments are possible where such a locally protruding portion is extending only in a region facing away from said first section, or in a region facing away from said second section.
