Description
SPECIFICATION
Container coding
This invention relates to the coding of containers, and especially to the coding of glass containers such as bottles and jars.
The manufacture of glass containers is a highly automated procedure. Molten glass is fed from a furnace to one or more moulding machines, in which the glass, in the form of individual gobs, is pressed and/or blown into shape in mould cavities. Several different types of glass making machine are known, and they operate on the multi-mould cavity principle. In other words, it is normal for a machine to comprise at least eight moulds, and many machines have twelve, sixteen or even twenty-four moulds which are simultaneously operating to produce moulded glass containers. Each individual mould will produce some thousands of containers per day, if the machine is operated continuously.
It sometimes happens that the glassware produced in glass-making machines is defective for one reason or another, and in some cases the defects are so bad that the ware cannot be supplied for the customers particular end use. It will normally be the case that the defective ware is produced in one, or perhaps two, moulds only, and it is therefore necessary that those moulds, and the ware produced by them, should be easily and readily identifiable so that the ware that is defective can be located and discarded.
It is also a requirement of packagers nowadays that, regardless of whether the glassware is defective, each article of glassware, e.g. each glass bottle or jar, should be readily identifiable as to its place of manufacture, the mould in which it was manufactured, and possibly even the data of manufacture.
For these reasons it has recently become necessary to provide glassware with distinguishing markings, or codes, by which their precise location of manufacture may be identified. The present invention is concerned with the provision of a coding system for glass bottles and other glass containers.
According to the invention there is provided a coded glass container wherein the code comprises markings arranged on the base of the container along the circumference of at least two concentric circles.
The invention also provides glass-making moulds which are configured to provide the glassware
manufactured in them with the markings described
immediately above.
The coding system of the invention may be
applied to glass containers of various shapes. Thus,
it may be applied to bottles having round bases, in which case the concentric circles will have a finite
radius, suitably only slightly smaller than the radius
of the base (i.e. the markings are sited adjacent the
periphery of the base); or it may be applied to bottles
having bases which are other than round, e.g.
rectangular, in which case the concentric circles may
have an infinite radius and the two sets of markings
will occupy positions on parallel straight lines,
preferably along one or both edges of the base of the container. For containers whose bases are neither round nor rectangular it will be preferable to adopt a system of parallel straight line code markings
The markings suitably comprise bars, which are preferably projections but may be identations, moulded into the base of the container, the midpoints of which are on the circumference of at least two concentric circles. The bars are suitably arranged along the radii of such circles, i.e. they will be parallel in the case of rectangular bases, although they may be arranged at an angle to such radii.
The markings, which will differ from mould to mould, will preferably be such as may be scanned by an optical scanner which converts the patterns generated by them into electrical pulses which are then electronically decoded. The use of bars as the code markings makes the containers of the invention eminently scannable by means of a camera containing a linear array of photo-detectors, e.g. photodiodes.
The accompanying diagrammatic drawings are views of the bottoms or punts of glass bottles bearing coding marks in accordance with the invention, Figure 1 showing the punt of a round bottle and
Figure 2 that of a rectangular bottle.
Referring to Figure 1, the base of the bottle is provided with an outer set of equi-spaced radial bars 1, the mid-points of which lie on the circumference of a notional circle 2. The bars 1 may take the form of the usual stippling.
A further series of bars 3 is provided, the midpoints of each of which lie on the circumference of a notional circle 4. The circles 2 and 4 are concentric.
The coding is made up of the combination of bars 1 and bars 3, and in the illustration the particular code shown occupies the portion "A" of the base of the bottle. The code combination shown therefore consists of a bar 3 and no bar 1; no bar 3 and a bar 1; a bar 3 and a bar 1; a bar 3 and a bar 1; no bar 3 and a bar 1; no bar 3 and a bar 1; a bar 3 and a bar 1; no bar 3 and a bar 1; a bar 3" and no bar 1. Such a combination of bars would be unique and attributable to a single glass-making mould only. All the containers having this particular combination of code bars will thus have been made in that particular mould.
The code may be scanned by a linear diode array camera, suitably contained in a circuit which pays no attention to a sequence of successive bars 1 but which is triggered by the lack of a bar 1 and the presence of a bar 3, (i.e. that shown as 3'), after which it analyses the remainder of the binary code group "A" and compares the information obtained therefrom with information stored in a memory and, if required, indicates that a particular code has been identified. The presence of a further bar 3 (that as shown as 3") and no bar 1 indicates the end of the code and confirms that the full code, in this case the seven bits of information between bar 3' and 3", has been received.
Figure 2 shows the base of a rectangular bottle, which is provided with an outer set of bars 10, which for the most part may take the form of usual equi-spaced stippling, and an inner set of bars 11, the combination of inner and outer bars in each of the regions labelled "B" and "C" making up the coding in this example. In the example shown the coding in each of regions "B" and "C" is identical, so that if a code scanning or camera viewing device is aligned with a long edge of the bottle it does not matter which way round the bottle is when it comes within the field of the viewing device.
The coding illustrated in Figure 2 is precisely the same as that shown in Figure 1, and consists of seven bits of information between the trigger bar 11' (a bar 11 and no bar 10) and the bar 11" (a bar 11 and no bar 10) which signifies the end of the code. Thus the code in this case, along both long edges of the container, consists, between bars 11' and 11", of no bar 11 and a bar 10; a bar 11 and a bar 10; a bar 11 and a bar 10; no bar 11 and a bar 10; no bar 11 and a bar10; abar11 anda bar10; no bar11 anda bar10.
As before, this particular combination of bars 10 and
11 will relate uniquely to one particularforming mould, the identity of which is stored in a memory
linked to the device which scans the code.
It will be appreciated that the coding system
described in particular herein make use of two sets of code bars. The use of three or more sets is of course possible and will increase the number of available combinations and thus the possible number of code identities.
Claims (9)
1. A coded glass container wherein the code comprises markings arranged in tracks on the base of the container along the circumferences of coincident sectors of at least two concentric circles, the markings in one track (herein termed the first track) being formed by substantially equispaced stippling marks provided towards the edge of said base except in positions defined by the two radii respectively defining the boundary of said sectors whereat said stippling marks are absent.
2. A container according to claim 1 wherein the code comprises markings arranged in two tracks.
3. A container according to claim 1 or 2 wherein the first track is the outermost track.
4. A container according to any of claims 1 to 3 wherein markings in the second track are colinear with markings in the first track except in said positions defined by the said two radii.
5. A container according to claim 4 wherein said markings intersect the centre of said concentric circles.
6. A container according to any of claims 1 to 5 wherein a marking is always present in said second track colinearwith said two radii defining the said boundary of said sectors.
