Description

A CONTAINER AND A CLOSURE THEREFOR This invention relates to a container closure assembly which comprises a container neck and a closure. In particular, the invention relates to an assembly in which a reliable seal is formed when the closure is fitted to the container neck.
Such closure assemblies are often used in containers for food, drinks, medicines or other perishable or contaminable contents, to preserve the quality of the container contents.
One known arrangement for a sealing closure assembly is for the closure to be provided with an annular sealing wall which fits inside the container neck, and forms a seal against the radially inner surface of the neck when the closure is fitted on the neck.
A problem which may be encountered with conventional closure assemblies, such as that described above, is that with a screw threaded closure, for example, the closure has to be screwed down tightly to ensure that a reliable seal is formed. This means that the closure may be difficult to remove later, and it may also cause damage by deforming the engaging surfaces of the closure and the neck.
The present invention aims to overcome these and/or other drawbacks.
In a first aspect the invention provides a container closure assembly comprising a container neck, a container closure, means for retaining the closure in a closed position on the neck, first sealing means on the closure adapted to seal against an outer surface of the neck when the closure is in its closed position, and second sealing means on the closure adapted to seal against an inner surface of the neck when the closure is in its closed position.
With such an arrangement, the closure when fitted to the container neck forms a seal against both the inner and outer surfaces of the container neck. This sealing arrangement can provide a more reliable seal than a conventional seal, without requiring the closure to be fastened down very tightly on the container neck.
The outer surface of the neck against which the first means is adapted to form a seal may be a circumferentially facing outer surface, or it may alternatively be any other surface, such as a top surface, on the outside of the container neck.
Preferably, the first and second sealing means form respective seals with the container neck at positions which are substantially directly opposite each other. This can further improve the sealing effect by "wedging" the wall of the container neck between the first and second means of the closure.
Preferably, the first sealing means comprises an inner surface of a skirt portion of the closure, which inner surface is adapted to seal against the neck. The outer surface of the neck may include an outwardly tapered portion, and the inner surface of the skirt portion of the closure may be adapted to form an interference fit with the outwardly tapered portion of the neck. The skirt portion of the closure may include an inwardly tapered surface to form a complementary fit with the outwardly tapered portion of the neck.
The angle of taper of the tapered portion of the neck may be between about 10 and 450, preferably between about 10 and 250, and in particular about 50.
The second sealing means preferably comprises a plug portion of the closure, which plug portion is shaped to fit inside the container neck, the circumferential surface of the plug portion being adapted to seal against the inner surface of the neck.
Preferably the inner surface of the container neck includes an outwardly tapered portion, the circumferential surface of the plug portion being adapted to form an interference fit with the tapered portion of the neck. The plug portion may include an inwardly tapered surface to form a complementary fit with the outwardly tapered inner surface of the neck. The angle of taper may be between about 10 and 450, preferably between about 10 and 250, and in particular about 50.
The angle of taper of the inner surface of the neck preferably matches the angle of taper of the outer surface of the neck.
In the case where the container neck and the closure are of circular section, the means for retaining the closure in its closed position preferably includes a thread. Most preferably a thread is provided on the closure and a complementary thread on the container neck. As illustrated in one of the preferred embodiments, the threads are preferably of square section to provide a positive fit. The threads are preferably arranged so that the closure can be moved between the closed position and an open position by relative rotation through 1800 or less, for example, through 900. The invention is suitable for such an arrangement because it does not rely on the closure being fastened down especially tightly to achieve a reliable seal.
Alternatively, the retaining means might comprise a snap fit connection between the closure and the container neck.
The closure may comprise a handle in the form of an upstanding diametric flange. Such a handle is particularly convenient for use with both a screw threaded fastening closure and a snap-fit fastening closure. The handle enables a person to grip the closure easily by hand to remove, or fasten, the closure.
In a second aspect, the invention provides a closure adapted to fit a container neck, the closure comprising first sealing means adapted to seal against an outer surface of the neck when the closure is in a closed position on the neck, and second sealing means adapted to seal against an inner surface of the neck when the closure is in the closed position on the neck.
The first sealing means may comprise an inner surface of a skirt portion of the closure, which inner surface is adapted to seal against the neck. The skirt portion may be tapered inwardly, for example, to compliment an outward taper of the neck.
The second sealing means may comprise a plug portion of the closure, which plug portion is shaped to fit inside the container neck, the circumferential surface of the plug portion being adapted to seal against the inner surface of the neck. The surface of the plug portion may be tapered, inwardly for example, to compliment an inward taper of the inner surface of the neck.
The first and second sealing means are preferably directly opposed so that when the closure is fitted to a container neck, the first and second sealing means form respective seals with the neck at positions which are substantially directly opposite each other.
The closure may further comprise a screw thread, or snap-fit connecting means, for retaining the closure on the neck in the aforementioned closed position. The closure may comprise a handle in the form of an upstanding diametric flange to enable the closure to be gripped easily by hand to remove, or fasten, the closure.
Three embodiments of the invention are now described by way of example, with reference to the accompanying drawings, in which: FIG. 1 is a sectional view of part of a screw threaded container closure assembly; FIG. 2 is a sectional view of part of a snap-fit container closure assembly; and Fig. 3 is a sectional view of part of a modified snapfit container closure assembly.
Referring to Fig. 1, a container neck 10 is shown with its closure 12 in its closed, sealed position on the neck 10. In this exemplary embodiment, both neck 10 and the closure 12 are of circular section and are provided with complementary screw threads 14, 16, respectively. The threads 14 and 16 are of square section to provide a positive fit. The threads are arranged such that the closure can be moved between the closed position and an open position by relative rotation through about 900.
The upper portion of the neck 10 is tapered outwardly on its outer surface 18, and on its inner surface 20. The angle of taper is about the same on both surfaces 18 and 20, and is approximately 5 .
The closure 12 consists of a crown portion 22, a handle portion 23, a skirt portion 24, and an annular plug portion 26 fitting inside the container neck 10. The handle portion 23 is in the form of an upstanding diametric flange, which enables a person to grip the closure easily to fasten, or remove, the closure. The skirt portion 24 includes first sealing means in the form of a first sealing surface 28 which is adapted to form an interference fit seal against the radially outer surface 18 of the neck 10. The first sealing surface 28 is tapered inwardly to compliment the taper of the outer neck surface 18. The plug portion 26 includes second sealing means in the form of a second sealing surface 30 which is adapted to form a seal against the radially inner surface 20 of the neck 10.The second sealing surface 30 is also tapered inwardly to compliment to taper of the inner neck surface 20.
In this embodiment the first and second sealing surfaces 28 and 30 of the closure form seals against radially opposite faces of the container neck at positions which are substantially directly radially opposed. The upper portion of the neck is "wedged" between the sealing surfaces, which achieves a particularly reliable and effective seal.
It is to be noted, however, that in an alternative embodiment of this invention, the first and second sealing surfaces might not be directly radially opposed. For example, the first sealing surface 28 could instead be arranged below the screw threads 14.
The container neck and the closure are preferably made of material which enables a reliable seal to be formed by the interference fits between the sealing surfaces of the closure and the container neck.
Fig. 2 shows a similar arrangement of sealing surfaces for a snap-fit closure assembly. Where appropriate, the same reference numerals of Fig. 1 are used to denote corresponding features of Fig. 2. The main difference in Fig. 2 is that the screw threads are replaced by a lip 40 on the container neck 10, and an inwardly facing deformable snap-fit projection 42 on the closure 12 for engaging under the lip 40. The closure 12' is made of a deformable material such as deformable plastics. The arrangement includes the same first and second sealing means as described above to ensure that a reliable seal is made when the closure is fitted to the container neck.
Fig. 3 illustrates a modification of the embodiment in Fig. 2. In the modified embodiment, the flange handle is replaced by an annular protrusion 44 which projects radially outwardly near the lower edge 46 of the closure. The wall of the container neck is inclined to provide a clearance 48 under the lower edge 46 of the closure. With this arrangement, to remove the closure from the container neck, a person can grip around the annular protrusion 44, and under the lower edge 46 of the closure, to get a good grip.
Although in the embodiments described above, the first and second sealing means comprise sealing surfaces of the closure, in other embodiments sealing elements might be fitted to the closure to form the first and second sealing means. For example, sealing elements made of compressible material, e.g. rubber, could be used.
Although in the embodiments described above, both the inner and outer surfaces of the neck include tapered portions, in alternative embodiments, only one, or possibly neither, of the outer surfaces might be tapered. The sealing surfaces of the closure might still be tapered, or instead one or both of the sealing surfaces might not be tapered. The actual arrangement used can be varied to meet the requirements of the container and closure for a particular application.
It will of course be appreciated that the invention has been described above purely by way of example and that modifications of detail may be made without departing from its scope.
