Definitions
- This invention is concerned with improvements relating to bottle caps, particularly of the kind (hereinafter referred to as being of the kind specified) which are provided with an internal screw thread, enabling them to be screwed onto the neck of the bottle to sealingly close the bottle and to be unscrewed for dispensing the contents of the bottle.
- Bottle caps of the kind specified are conventionally manufactured by a moulding process, and at the appropriate stage in the bottling operation, are screwed onto the neck by machine. This is a slow and cumbersome operation, and moreover suffers from the disadvantage of ensuring that the cap is tightly sealed.
- a bottle cap of the kind specified comprising circumferential location means to enable the cap to be located in a desired rotational position.
- such location of the cap may be utilised simply to correctly align the threads of the cap with the threads on the neck, ensuring proper closure of the cap by a specific amount of rotation.
- the cap may be pressed onto the neck, the threads of the cap being deformed over the threads of the bottle into the axial and orien- tational position which would be adapted by the cap had it been screwed onto the neck properly.
- a method of applying a bottle cap of the kind specified to the neck of a bottle in which the cap is positioned adjacent to the neck in axial alignment therewith in a specific rotational orientation, and pressing the cap onto the neck.
- Preferably said method involves conveying the caps in serial array utilising a guide means which is engaged by the location means and causes the caps to be orientated into a desired position.
- a bottle a neck of which is exteriorally threaded, and a cap capable of being screw threaded onto and from the neck, wherein the cap is provided with location means enabling the cap to be rotationally oriented into a desired position in relation to the start of the thread or threads.
- a plurality of location means are provided, preferably one corresponding to each thread start.
- the location means comprises a formation projecting radially from the cap, preferably from a cylindrical wall thereof.
- the location means is located on the tamper-evident ring.
- location formations preferably they are arranged at 120° radial separation, and are preferably so arranged that the distance between them is close to, preferably slightly smaller than, the diameter of the wall on which they are mounted, so that the location formations may cooperated with guide means to cause the caps to adapt a specific orientation.
- the cap 4 which is the preferred embodiment of the invention is generally conventional, comprising a circular wall 6, a cylindrical side wall 8, and a tamper-evident ring 10 secured to the wall 8 by easily fracturable tabs.
- the wall 8 On the interior the wall 8 is provided with thread formations 12, which in the preferred embodiment are three-start.
- the distance X between each pair of formations as measured between outer tangents thereto, is approximately the same as, or slightly smaller than, the diameter Y in the corresponding part of the cylindrical wall from which the formations 10 extend.
- each cap may be fed in turn over the neck of a filled bottle, with the cap and the neck in axial alignment, with the threads of the cap in a known, desired relationship with the threads of the neck, and by pressure alone the cap may be fitted onto the neck so as to be in sealing engagement therewith, the design of the tamper-evident ring facilitating this operation.
- the cap may be unscrewed from the neck, causing the tamper evident ring to fracture, and may subsequently be used to reclose the bottle.
- a cap may be fitted onto a bottle by the use of pressure alone, increasing significantly the speed at which a bottling and capping operation may be effected.
