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, particularly containers for carbonated beverages, 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.
- 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 external surface of the web at a point intermediate its ends, as seen in axial sectional view, or to the internal surface of the first tubular portion 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 or the external surface of the web.
- the features in accordance with the invention inherently mean 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 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 the flow openings are unobstructed, and a closed position, in which 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.
- 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 may carry 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 2 is an axial sectional view of the drinking cap, when closed.
- 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.
- 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 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 upwardly, that is to say towards the lid 14, and inwardly towards the axis of the cap, whereby it subtends an acute angle with the axial direction of the cap.
- the tubular portion 6 When the cap is in the open position shown in Figure 1, the tubular portion 6 is located substantially within the tubular portion 2.
- the web 4 extends downwardly from 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.
- a user can readily drink a beverage from the bottle by placing his lips around the outer surface of the tubular portion 2, which will act in the manner of a drinking spout. If an upward force is exerted on the cap 14, the tubular portion 6 begins to move upwardly. This results in compression and distortion of the web 4, which thus exerts a restoring force on the tubular portion 6 urging it back towards the fully open position.
- the tubular portion 6 moves upwardly until the web 4 extends approximately horizontally, that is to say in the radial direction. As the tubular portion 6 moves through and beyond this "dead centre" position, the force exerted by the web 4 on the tubular portion 6 acts in the upward direction. The tubular portion 6 continues to move upwardly and this is accompanied by continuing rotation of the web 4. This movement continues until the free edge of the sealing flange 20 engages the surface of the resilient sealing flange 22.
- the modified embodiment shown in Figure 3 is very similar to that in Figures 1 and 2 and differs from it in only two respects. Firstly, the flange 22 is omitted and the flange 20 on the web 4 engages the internal surface of the tubular portion 2. In this case, the upper portion 30 of the tubular portion 2 is inclined upwardly and inwardly and thus functions in a manner very similar to that of the flange 22. However, this portion 30 need not be so inclined and could merely constitute a portion of the tubular portion 2 which extends parallel to the remainder of the wall of the tubular portion 2.
