DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a dispensing-sealing arrangement for a container.
BACKGROUND OF THE INVENTION
There is a need to provide a dispensing-sealing arrangement for a container which allows both the convenient transferring of the contents of the container to the user and the ability to re-seal the container to prevent the leakage of the contents and maintain its integrity. One example of this is the humble baby bottle. A major drawback With the use of baby bottles is the need to sterilize the bottle and associate teat prior to use. At times it would be of greater convenience to use a disposable pre-filled baby bottle if such were available. It is thought that one reason why such bottles are not widely available is the difficulty in providing a reliable arrangement for dispensing the contents of the baby bottle and sealing the baby bottle in a manner so as to minimise contamination of the contents.
It is also known that the screw caps on many carbonated drink bottles do not maintain the integrity of the contents in that after initially opening the bottle and resealing, the caps allow the leakage of carbon-dioxide resulting in the drink becoming flat.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a dispensing-sealing arrangement for a container which attempts to alleviate at least one of the disadvantages in the above-described prior art.
According to the present invention there is provided a dispensing-sealing arrangement for a container comprising: said container and having an outlet for dispensing matter contained in the container; and, sealing said container by deforming said dispensing means in such a manner that a first portion of said dispensing means is sandwiched between said opening and said sealing means, said sealing means being configured so that sufficient pressure is applied to the dispensing means to ensure positive sealing between the dispensing means and sealing means.
Preferably, said sealing means is provided with releasable engaging means for releasably engaging a second portion of said dispensing means when the cap is inserted into said opening whereby, in use, said cap, when removed from said opening, initially extends said dispensing means from said opening and is subsequently released from said dispensing means.
Preferably, said sealing means comprises a first skirt depending from an upper wall of said cap, said first skirt having an inner surface which, together with said upper wall, defines said engaging means for engaging said second portion by resiliently deforming said second portion against said inner surface of the first skirt.
Preferably, said outlet is located in said second portion of the dispensing means and said first skirt is configured so that said outlet abuts said upper wall when the second portion of the dispensing means is engaged in the engaging means thereby sealing the outlet.
Preferably, said cap further comprises a second skirt depending from a peripheral edge of said upper wall in the same direction as said first skirt, said second skirt being configured to fit over and releasably engage an exterior surface of said container.
Preferably, said second skirt is further configured so as to form a seal about said exterior surface.
In an alternate form said dispensing means further comprises a third portion depending from said first portion and adapted for extending through said opening into said container to a position where it can overlie a bleed hole provided in the container, whereby, when said cap is removed from said opening and the difference between ambient atmospheric pressure and pressure inside said container is greater than a predetermined pressure said third portion acts to allow fluid communication between the atmosphere and the inside of container through said bleed hole, and when said difference is less than or equal to said predetermined pressure said third portion seals said bleed hole to substantially prevent escape of contents of said container through bleed hole, and when sai
