Abstract

A lid (1) for a drinks container has a mouthpiece (6) provided with a valve (2) which comprises a membrane (7) of resiliently flexible material formed generally at its centre with at least one slit or other piercing (8) which is normally sealed. The membrane (7) is dished inwardly of the mouthpiece, but when suction is applied, it is caused to invert to allow liquid to be drawn through its slit(s) (8). The valve (2) may instead be provided in the top of a drinks carton or in the end of a drinking straw.

Description

Drinks Containers
This invention relates to drinks containers or vessels, including drinking vessels suitable for use as a trainer cup or the like.
Traditionally, trainer cups (that is, a cup or mug provided with a lid having a mouthpiece associated therewith, usually in the form of a spout) have been used by young children to bridge the gap between use of a baby's feeding bottle and use of a normal cup or glass. The trainer cup is often the child's first step in learning to feed itself. The provision of a lid with a spout is intended to make it easier for the child to feed itself, because it can locate the spout in its mouth in much the same manner as it could previously locate a teat of a feeding bottle in its mouth. However, young children of this age are naturally exuberant. Eating becomes a noisy and messy experience. The trainer cup is often shaken violently or knocked over. In either event, with a traditional trainer cup, this results in spillage. For travel purposes, a separate closure disc needs to be fitted to the cup underneath the lid, or the lid is required to have an adjustable closure arrangement.
My UK patent application No. 2 266 045 described a number of drinking vessels which were suitable for use as a trainer cup or cup for the elderly or infirm. Such drinking vessels comprised an open-mouthed, generally cup-shaped container and a lid for covering the open mouth of the container. The lid had an associated mouthpiece. Valving was provided to prevent flow of liquid from the interior of the container through the mouthpiece unless a predetermined level of suction was applied to the mouthpiece, and such that a user could draw liquid through the mouthpiece by the sole application of suction to the mouthpiece. The arrangements have proved successful in overcoming the problem of spillage, but are of relatively complicated and expensive construction.
In accordance with the present invention, there is provided an article through which or from which a drinking liquid is taken by a consumer, the article being provided with a valve which comprises a membrane of resiliently flexible material which is dished inwardly of the article, opposite the direction through which the drinking liquid is taken in use of the article, said membrane being formed generally at its centre with at least one slit or piercing.
In the normal condition of the valve, the orifice provided by the slit(s) or piercing is closed, i.e. the material of the membrane closes up under its own resilience. Also, if there is moderate internal pressure acting outwardly on the valve, e.g. the weight of the contents of a container or vessel bearing down on the valve when the container or vessel is inverted, then this pressure helps to urge the material of the membrane, on opposite sides of the slit(s) or piercing, to close together. However, the valve opens to allow the free flow of liquid through the valve if suction is applied e.g. by the mouth. For example, the valve may be provided in a projecting mouthpiece of a container or lid for the container: then if the mouthpiece is inserted into the user's mouth and the user applies suction, this causes the flexible membrane to invert and the slit(s) or piercing to open and so allow the free flow of liquid. The valve may be incorporated in the top of a drinks carton: either suction can be applied as described above for drinking directly from the carton, or the carton can be squeezed to increase its internal pressure and expel the liquid through the valve, to pour the liquid into a separate vessel. In all cases however, a drinking straw may instead be pushed through the orifice in the valve, and the user may then drink through this straw. When suction is applied, the dished membrane is caused to invert and allow liquid to be drawn through its orifice, then when the suction is released, air passes through the orifice into the container, to equalise or nearly equalise the pressures either side of the valve: further, the valve assumes its normal condition (i.e. dished inwardly) under its own resilience.
Slit valves have been proposed in the past, but in general, such slit valves have been dished or domed in the direction of the flow. So far as I am aware, it has never previously been proposed to provide slit valves dished in the direction opposite to the flow direction of the liquid which they control or, more particularly, a slit valve dished in the direction contrary to the flow of liquid which it is designed to control and which also allows flow of air in the opposite direction to the liquid flow.
In a preferred arrangement, the valve membrane is co- moulded with the container, or lid for a container, internally thereof. In the case of a lid having a mouthpiece, these are preferably formed in a single piece with a circumextending skirt at the lower end of the lid, enabling the lid to be fitted within the open mouth of a cup-shaped container, a radial circumextending ridge serving to limit entry of the skirt into the open mouth. In a further embodiment, the valve may be incorporated into the end of a drinking straw. In this case, the straw may be inserted into a conventional carton, piercing its usual foil membrane but then forming a relatively effective seal: the valve in the straw then provides for use of the combination in the manner described above.
Embodiments of the present invention will now be described by way of examples only and with reference to the accompanying drawings, in which:
FIGURE 1 is a section through- the lid for a drinking vessel; and
FIGURE 2 is a schematic view of a drinks carton. Referring to the drawings, there is shown a lid 1 for use on an open-top cup-shape container 10 of conventional form. The lid 1 is of a one-piece construction and is co-moulded together with a valve generally indicated at 2. The lid 1 is provided with an integral, peripheral skirt 3 on its lower side, the upper edge of which skirt is bounded by a peripheral ridge 4 which extends radially outwardly. When the lid 1 is fitted to the open-top of its cup-shaped container, the skirt 3 extends downwardly within the cup and the ridge 4 sits on the upper peripheral edge of the cup. This provides an adequate seal to prevent spillage. The only opening in the lid 1, other than that bounded by the skirt 3 , is an opening 5 in an upwardly-projecting mouthpiece 6. The general shape of the mouthpiece 6 may be similar to that of traditional trainer cups. The difference lies in the provision of the valve 2. Valve 2 is formed from a resiliently flexible sheet or disc 7, which may be of rubber or more preferably of plastics material, and has one or more slits 8. A single slit may suffice; a preferred arrangement employs a pair of slits which intersect to form a cross-cut. The or each slit is literally a slit or division rather than an open slot so that in the natural condition of the valve, in which the sheet 7 forming the valve is dished slightly inwardly of the mouthpiece, the or each slit 8 is fully closed thereby preventing egress of liquid from the interior of the vessel or ingress of air from outside the vessel. An orifice may be provided in the disc 7, instead of the slit or slits 8, by piercing the disc with a pointed implement: in all cases, the slit or other orifice is formed by severing through the disc without removing any material thereof.
The material of the lid 1, apart from the flexible valve sheet 7, is suitably made of a relatively hard plastics material such as polycarbonate or polypropylene. The material of the valve sheet 7 is selected εo that it can readily be co- moulded with the mouthpiece. If the flexible sheet is formed of a similar plastics material to the remainder of the lid 1, such co-moulding is facilitated. This can be achieved by making the sheet 7 significantly thinner so as to give is enhanced flexibility as compared with the remainder of the lid, or by producing it in a similar plastics but with a greater amount of plasticizer. In the case of the ther ohardening plastics material, the material of the remainder of the lid can be partially cured before the material for the flexible sheet is added to the mould and then the cure continued for a further period so as to harden the lid but only partially harden the material of the sheet 7. Alternatively, the sheet 7 can be formed as a separate piece and of a plastics material which does not harden with heat and may be inserted into the mould with material for forming the remainder of the lid, the remainder of the lid being formed of a thermohardening material so that curing hardens the remainder of the lid and integrates the valve sheet into the mouthpiece. In a preferred arrangement, the remainder of the lid is formed of polypropylene and is pre-formed in the mould. The material for the sheet 7 is then added into the mould in the required region as a liquid and is then cured. The preferred material for the sheet 7 is a block co-polymer sold under the Trade Mark EVOPRENE which comprises a styrene-ethylene-butylene-styrene copolymer.
Other arrangements will readily occur to those skilled in the plastics moulding arts. With the arrangement described and illustrated, there is no leakage through the orifice 8, in the natural unbiased condition of the valve; if a predetermined suction is applied to the mouthpiece, the flexible sheet 7 will be drawn upwardly, opening the orifice 8 and allowing liquid to the drawn out. Release of the suction will allow air to pass backwardly through the same orifice 8 until the valve returns to its original condition in which position the valve will again be closed. Under the influence of normal internal pressure, for example if the container is inverted, this pressure will tend to urge together material of the sheet 7 either side of its orifice 8, and so close the orifice.
Although use of the valve has been described hereinabove with a view to its incorporation in a particular article of manufacture, namely the lid of a trainer cup or cup for the elderly and infirm, the valve is of much wider utility. The valve may in particular be incorporated into the top of a drinks carton 20, as shown in Figure 2. In such case, the user may drink from the carton 20 by offering the valved portion of the carton to the mouth and applying suction, or by inserting a drinking straw through the orifice in the valve 22. In either case, liquid can be expelled from the carton by squeezing the carton to increase its internal pressure. In a further embodiment (not shown) , the valve may be incorporated into the end of a drinking straw: the straw can then be inserted into a conventional carton, piercing its usual foil membrane but then forming a relatively effective seal; the valve in the straw then provides for use of the combination in the same manner as described above with reference to the drawing.
