Definitions

  • the present invention relates to dispensing caps for liquid bottles or other containers.
  • the invention is particularly concerned with drinking caps for beverage containers but relates also to dispensing caps for containers for liquids such as detergent or flowable foodstuffs.
  • Such dispensing caps typically include two moulded plastic components which are connected together and are relatively movable between a first position, in which the bottle, to which the cap is connected, is sealed and a second position, in which the interior of the bottle communicates with the exterior through one or more openings through which a liquid in the bottle may flow.
  • Such caps thus provide a resealing facility and, in the case of a drinking cap, the ability to drink from the bottle without removing the cap.
  • the two separate components must be moulded separately and then connected together. This is both time-consuming and expensive.
  • One-piece dispensing caps are known and DE-G-8518074.2 discloses such a cap of the type including a first circular section tubular portion with a first radius for connection to the mouth of a container and a second circular section tubular portion with a second radius smaller than the first radius, one end of the first tubular portion being connected to one end of the second tubular portion by a resilient, annular, integral web, in which one or more flow openings are formed, the width of the web being equal to or greater than the difference between the first and second radii, the other end of the second tubular portion being closed, the web and the internal surface of the first tubular portion adjacent the said one end thereof being connected to a projecting annular first sealing flange, the first and second tubular portions being coaxial and relatively movable in the axial direction between an open position, in which the second tubular portion is located outside the first tubular portion and the flow openings are unobstructed, and a closed position, in which the said one end of the second tubular portion is located within the said one end
  • the cap disclosed in this document is for dispensing powdery solid materials and not liquids and would be inherently unsuitable for use on a liquid container because it is incapable of forming a reliable liquid seal.
  • the sealing flange and the web are in surface contact.
  • Such surface contact is incapable of providing a reliable seal because the contact force is inherently very low and exerted over a substantial area, whereby the contact pressure is extremely small.
  • it is impossible to form the two engaging surfaces completely smooth and complementary and the resulting inevitable gaps will mean that any liquid in the container will be subject to leakage.
  • a dispensing cap of the type referred to above for use with liquid containers is characterised in that the first sealing flange is integrally connected to the web at a point intermediate its ends, as seen in axial sectional view, whereby when the cap is in the closed position the free edge of the first sealing flange forms a substantially line seal with the internal surface of the first tubular portion.
  • the feature in accordance with the invention inherently means that when the cap is in the closed position the web and the sealing flange are not in flat surface contact but instead the free edge of the sealing flange is in line contact with the internal surface of the first tubular portion.
  • This contact is inherently a line contact means firstly that the contact pressure is very much higher than in the prior document and secondly, partly as a result of the higher pressure, that problems resulting from surface irregularities are eliminated. A reliable liquid seal is thus created.
  • the dispensing cap in accordance with the invention includes two circular section tubular portions of different radius, one end of each of which is connected by a resilient web whose width, that is to say length in the generally radial direction, is equal to or greater than the difference between the two radii.
  • the other end of the tubular portion of greater radius is adapted for connection to the mouth of a bottle or the like whilst the other end of the tubular portion of lesser radius is closed.
  • the resilient web has at least one and preferably a number of spaced flow openings formed in it.
  • the web carries a sealing flange connected to it at a point intermediate its ends, as seen in axial sectional view.
  • the tubular portion of lesser diameter is thus movable in the axial direction with respect to the other tubular portion between an open position, in which it is situated wholly outside the tubular portion of greater diameter and the flow openings are unobstructed, and a closed position in which its end connected to the web is situated inside the adjacent end of the tubular portion of greater diameter.
  • the flow apertures are situated within the tubular portion of greater diameter and the sealing flange is in sealing engagement with the internal surface of the tubular portion of greater diameter, thereby sealing the flow openings from the interior of the tubular portions.
  • the sealing flange is positioned and dimensioned such that it is moved into sealing contact with the opposing surface on the internal surface of the tubular portion of larger diameter before the web has reached the fully relaxed position. This means that, in the closed position, the sealing flange is biased into contact with the opposing surface and forms a constant substantially line seal with it.
  • the first sealing flange projects from the web in a direction substantially parallel to the axis of the first and second tubular portions, when they are in the open position. This is particularly convenient because it enables the dispensing cap to be readily removed from an injection mould at the end of the injection moulding process in the axial direction. It is also convenient because the web, and thus the first sealing flange integral with it, will typically rotate through about 90° when moving from the open to the closed position, which means that if the first sealing flange extends in the axial direction, when the cap is in the open position, it will extend in the generally radial direction, when the cap is in the closed position, which will mean that its free edge will form a substantially line seal with the opposing surface.
  • first sealing flange may form a seal directly with the internal surface of the tubular portion of greater diameter
  • the internal surface of the first tubular portion carries a resilient annular second sealing flange, which projects at an acute angle to the axis of the first of the first and second tubular portions and away from the second tubular portion and is positioned so that it is sealingly engaged by the first sealing flange, when the first and second tubular portions are in the closed position.
  • This second sealing flange will be caused to yield somewhat in the generally radial direction by the engagement of the first sealing flange and this is found to result in a further enhancement of the sealing integrity.
  • the first sealing flange may be in the form of a simple laminar strip with a single free end which forms a seal with the internal surface of the first tubular portion. However, it may also be bifurcated, in axial sectional view, and thus have two free ends, both of which engage the internal surface of the first tubular portion in the closed position, and form a line seal with it. This yet further enhances the integrity of the seal.
  • the first tubular portion carries a radially projecting annular projection.
  • the first tubular portion canies an external annular stiffening or reinforcing bead adjacent its connection with the web. This stiffening bead will resist deformation forces and thus minimise the risk of inadvertent leakage occurring.
  • Figure 1 is a side view of the drinking cap, when open
  • Figure 2 is a side view of the drinking cap, when closed
  • Figure 3 is an axial sectional view of the drinking cap when open
  • Figure 4 is an axial sectional view of the drinking cap, when closed.
  • FIG. 5 is a scrap view of a modified construction of the first sealing flange.
  • the drinking cap is a one-piece injection moulded component of polymeric material, such as polypropylene, and comprises a first circular section tubular portion 2 of relatively large diameter, which is integrally connected at one end by a resilient, flexible web 4 to one end of a second circular section tubular portion 6 of relatively smaller diameter.
  • the larger tubular portion 2 is adapted to be connected to the neck of a bottle.
  • its diameter may be substantially the same as that of the neck of the bottle to which it is to be connected or, as in this case, it may be integral with a circular section connector portion 8 of yet greater diameter, that is to say with an internal diameter substantially equal to the external diameter of the neck of the bottle.
  • the connector portion 8 may be connected to the bottle in any convenient manner but in the present case it is provided with internal screw threads 10 for cooperation with corresponding screw threads on the exterior of the neck of the bottle, which is illustrated in part and designated 12 in Figure 2.
  • the upper end of the smaller diameter tubular portion 6 is closed by an integral lid 14, the diameter of which is greater than that of the tubular portion 6, whereby its radially outer edge constitutes a projecting flange or lip 16, which may be grasped by the user.
  • a plurality of holes 18 is formed in the resilient web 4.
  • the width of the resilient web 4 that is to say its length between the lower end of the tubular portion 6 and the upper end of the tubular portion 2, is greater than the difference between the radii of the two tubular portions.
  • a second resilient sealing flange 22 Integral with the internal surface of the upper end of the larger tubular portion 2 is a second resilient sealing flange 22, which extends both downwardly, that is to say away from the smaller diameter tubular portion 4, and inwardly towards the axis of the cap, whereby it subtends an acute angle with the axial direction of the cap.
  • the tubular portion 4 When the cap is in the open position shown in Figures 1 and 3, the tubular portion 4 is located wholly outside the tubular portion 2.
  • the web 4 also extends upwardly out of the tubular portion 2 and also inwardly in the axial direction and the flow openings 18 communicate with the interior of the cap, whereby liquid in the container to which the cap is connected can flow out through the openings 18.
  • the tubular portion 6 If a downward force is exerted on the cap 14, the tubular portion 6 begins to move downwardly. This results in compression and distortion of the web 4, which thus exerts a restoring force on the tubular portion 16 urging it back towards the full open position.
  • the tubular portion 6 moves downwardly until the web 4 extends approximately horizontally, that is to say in the radial direction.
  • the scrap view of Figure 5 shows a modified construction in which the sealing flange 22 is bifurcated at its free end and thus has two spaced free ends 26. When the cap is closed, both of these free ends will form a sealing line engagement with the flange 22 and this further enhances the integrity of the seal.
