RZ.. rvu v''% ^ri i » 1 FEB i984 " Patents Form No. 5 Number PATENTS ACT 1953 Dated COMPLETE SPECIFICATION TAMPERPROOF KEG SEAL J/We SCOTTISH & NEWCASTLE BREWERIES PLC, a British company of Abbey Brewery, Holyrood Road, Edinburgh EH8 8YC, Great Britain, do hereby declare the invention for which if we pray that a Patent may be granted to mo/us, and the method by which it is to be performed, to be particularly described in and by the following statement: - 1 - (followed by page la) -r i, 207016 la M.Z. PATgfryf C iTiSE 19SEP1985 RECErVtiD This invention relates to a method of and to apparatus for applying a tamperproof seal to containers such as for example beer kegs.
There is a requirement to provide a tamperproof seal for beer kegs. This is important as the seal should prevent any unauthorised person from removing beer from the keg and replacing the beer with another liquid without damaging the seal. In many other industries there is also a need for a similar type of container seal. Hitherto there have been great difficulties in providing such a tamperproof seal.
According to the present invention there is provided apparatus for applying a tamper resistant seal to a closure member fitted in a neck portion of a beer keg comprising: an input conveyor for kegs to be sealed; a sealing station; means at said sealing station for applying a cover member over said keg closure member; a sprayhead at said sealing station for applying sealing material to said cover member and neck portion of the keg to seal the cover member to the neck portion of the keg; 207016 2 means for positioning a masking device around said neck portion of the keg so as to prevent sealing material from covering any part of the keg other than the cover member and neck portion; and an output conveyor for sealed kegs.
Preferably said closure member is a plastics material disc.
The sealing material applied by said sprayhead may be a low melting point thermoplastic material or a water based PVC material.
Preferably also there is included means for applying a security mark to the sealing material after application of the sealing material to the closure member.
Embodiments of the present invention will now be described by way of example, with reference to the accompanying drawings in which: Fig. 1 is a perspective view of the neck of a beer keg with a seal applied to it in accordance with the invention; Fig. 2 is a sectional side view of the beer keg neck of Fig. 1; and Fig. 3 is a perspective view of a machine for applying a seal to a keg in accordance with the present invention.
Referring to Figs. 1 and 2, a beer keg has a neck 1 which is sealed in accordance with the invention. An adhesive plastics material disc 2 covers the valve assembly 20 and a peelable plastics material seal 3 extends around the neck 1. The plastics material 3 may be for example a low melting point thermoplastics material or a water based PVC 19 SEP 1985 1—I— ITfW^i . mxmr 20701S 3 material. The disc 2 serves to prevent the plastics material 3 entering the valve assembly 20. The plastics material 3 may optionally have an embossed security mark applied. A tag 4 on the disc 2 is sealed against the side of the neck 1, by the plastics material 3, and protrudes down below the plastics material 3.
The tag 4 on the disc 2 provides a tear strip for the legitimate opening of the seal. The seal cannot be removed, and the keg opened, without destroying the seal.
Referring now to Fig. 3, this shows apparatus for applying the seal of Fig. 1. A line of kegs 5 enter the machine in the direction of arrow 6 and are halted by a keg escapement gear 7. The kegs 5 are then released by the gear 7 at timed intervals and pass through a disc applicator 8 which applies one of the discs 2 to the top of the neck 1 of the keg 5 to cover the valve assembly 20. The keg 5 then enters the main part of the machine and is pushed by a keg lift 9 upwards so that the neck 1 protrudes through a hole in a masking device positioned below a rotating sprayhead 11 driven by a motor 12. The sprayhead 11 is supplied with the liquid plastics material 3 via pipelines 13 from supply tanks 14 which are pressurised by an air supply 15. The rotatable sprayhead 11 applies the plastics material 3 in liquid form around the neck 1 of the keg 5 so as to seal the disc 2 in position. After application of the plastics material 3 the keg 5 is lowered by the keg lift 9 and then passes beneath a heater 16 which dries the plastics material 3 so that it solidifies to form a peelable seal around the neck 1 of the keg 5. The sealed keg 5 then leaves the machine in the direction of arrow 17 and is then ready for distribution.
A cleaning device 18 is also provided to clean the masking device 10 and prevent a buildup of the plastics material 3.
The basic machine can be easi 1 v nyodified so as to be able to &Z. PATENT GPRS#' 19 SEP 1985 HHCBVHD 207016 4 apply seals to a wide range of different containers as well as beer kegs. For example similar types of seals can be applied to small containers such as bottles. 19 SEP 1985 received 207016

Claims (6)

WHAT WE CLAIM IS:
1. Apparatus for applying a tamper resistant seal to a closure member fitted in a neck portion of a beer keg comprising: an input conveyor for kegs to be sealed? a sealing station; means at said sealing station for applying a cover member over said keg closure member; a sprayhead at said sealing station for applying sealing material to said cover member and neck portion of the keg to seal the cover member to the neck portion of the keg; means for positioning a masking device around said neck portion of the keg so as to prevent sealing material from covering any part of the keg other than the cover member and neck portion; and an output conveyor for sealed kegs.
2. Apparatus for applying a tamper resistant seal to a container as claimed in Claim 1, wherein saidt cover member is a plastics material disc.
3. Apparatus for applying a tamper resistant seal as claimed in Claim 1 or 2, wherein the sealing material applied by said sprayhead comprises a low melting point thermoplastic material.
