Abstract
Description
- This invention relates to containers, more particularly bottles, having screw-threaded necks and to caps for such containers.
- When a screw-capped bottle containing a carbonated beverage is partly empty the liquid is more susceptible to shaking and disturbance, causing the carbon dioxide to come out of solution and create a substantial gas pressure in the bottle. It is well-known that the gas pressure may be sufficient to blow the cap out of the hands as the cap is unscrewed. The cap is thus potentially a missile capable of inflicting serious damage on property and person.
- According to this invention there is provided a container having a screw-threaded neck the screw-thread ridge of which is formed with one or more transverse notches in its length.
- In another aspect the invention provides a screw-cap the screw-thread ridge of which is formed with one or more transverse notches in its length. Such caps will normally be moulded from plastics materials.
- The invention also provides a container having a screw-threaded neck and a screw-threaded cap screwed on to said neck, the ridge of the screw-thread of the cap and/or of the container having one or more transverse notches in its length.
- Thus excess pressure in the container can be relieved during removal of the cap, as gas escapes across the screw-thread by way of the notch or notches.
- It is preferred to provide a plurality of said notches, and notches in successive turns of the thread may be formed in axial alignment with each other so as to shorten the escape path. However, where the notches are formed in the screw-thread on the container, and the cap is a metal cap rolled on to the thread, the notches should not be of such size as to produce a complementary formation on the cap, and it may be preferable also that the notches in each turn of the thread be circumferentially staggered with respect to those in the other turn or turns so that minor irregularities in the thread on the screw-cap resulting from the rolling-on process are widely distributed along the thread and do not lead to "lumpy" movement of the cap during removal and replacement. '
- The notch or notches may have a radial depth equal to or less than the radial height of the thread- forming ridge.
- The distances measured along the ridge between adjacent notches may differ. For example the distances between adjacent notches may be greater at either end of the ridge than the other:
- Some embodiments of the invention are shown in the accompanying drawings and will now be described by way of example. In the drawings:
- Figures 1 and 3 each show diagrammatically the neck portion of a container according to the invention,
- Figures 2 and 4 are plan views corresponding to the threaded portion of Figures 1 and 2 respectively, and
- Figures 5 and 6 are respectively a sectional elevation and underneath plan of a cap embodying the invention.
- The container whose
neck portion 10 is shown is in the form of a bottle with an externalhelical ridge 11 constituting a screw-thread. At intervals along itslength notches 12 are formed in the ridge. Theportion 13 of the neck has, in the manner well-known in the art, a closely controlled external diameter and forms a seal with a complementary screw-cap (not shown). During removal of the cap, the seal at 13 is broken whilst the screw-threads on the cap and bottle are still well engaged, and any pressure in the bottle is then relieved by flow of gas past the sealing surfaces and thence through thenotches 12 and round the profile of the complementary thread-constituting ridge of the cap. The cap may be made from metal sheet and have a screw-thread rolled on to it, in the well-known manner, in substantial conformity with the thread on the.bottle, except for thenotches 12, the dimension of which lengthwise of the thread ridge should not be as to produce any corresponding interruption of the thread on the cap. - If desired, where the cap of the container is moulded from plastics material, the thread-constituting ridge of the cap may also be formed with notches . similar to the
notches 12. Alternatively the cap thread may be notched and the bottle thread un- notched. - The bottle may additionally have a peripheral rib (not shown) for the formation of a rolled-on pilfer- proof band, but the rib is immaterial to the invention.
- Figures 5 and 6 show a
cap 15 according to the invention. The cap is moulded from a suitable plastics material and has an internal screw-thread ridge 16 which is formed with a series oftransverse notches 17 spaced along its length. The radial depth of the notches is equal to the radial height of theridge 16. Such a cap can be used with a bottle having a conventional uninterrupted screw-thread ridge or with bottles such as are illustrated in Figures 1 to 4.Annular ribs annular surface 20 are provided to form a pressure-tight seal with the uppermost portions of the bottle neck.
