Definitions

  • the present invention relates to improving the hygiene of containers and in particular ring-pull cans
  • Food and drinks containers such as, for example, cans, bottles and tins are often provided with opening mechanisms in the form of a removable portion or seal to facilitate the removal of the contents Screw caps, stoppers, corks and push fit tabs are exemplary of such opening mechanisms
  • the ring-pull mechanism comprising a sealing tab and ring-pull
  • a sealing tab and ring-pull is well known for providing a readily removable seal for cans of food and drink, often carbonated drinks
  • the entire top of the container or can is removed by the ring-pull
  • the small, sharp edged nature of the tab or container section can cause safety problems, such as their being dropped into the can itself and subsequently swallowed, being dropped onto the ground and causing a hazard in the environment and even providing an effective missile or weapon
  • tabs were devised which remained attached to the can after opening
  • a portion of the tab or in certain designs the lid of the can actually dips into the drink
  • the external surfaces of the container could be accidentally or deliberately contaminated during manufacture or transport prior to purchase with consequential risk to the eventual consumer
  • the invention described below has as one of its aims the alleviation of such risks
  • a container having an opening mechanism comprising a removable portion or seal, the container further comprising barrier means, said barrier means being provided over the opening mechanism preventing contamination of the removable portion of the opening mechanism prior to opening the container, at least a part of the barrier means being removable sufficient to allow the opening mechanism to be freely operated and the contents to be removed
  • the container is a drinks container or a food tin
  • the container can be used to store cleaning fluids or alternatively oils to be introduced into, for example, an engine
  • the barrier means comprises a shrink wrap plastics material
  • the barrier means is provided with an adhesive layer to seal the barrier means to the container about the periphery of said barrier means
  • the barrier means preferably comprises score-marks or perforations to allow part or substantially all of the barrier means to be removed
  • a vacuum can be optionally introduced between the barrier means and the container
  • the barrier means preferably comprises a disinfectant or antibacterial compound
  • the barrier means can optionally comprise an indicator to indicate a breach in the integrity of the barrier means Conveniently, the indicator combines with oxygen to form a coloured compound
  • the opening mechanism preferably comprises a ring-pull mechanism having a tab or lid and a ring-pull
  • barrier means is removable
  • a method of manufacturing drinks containers or food tins including the step of securing a barrier material over an opening mechanism of the container
  • the step comprises shrink wrapping a plastics material barrier over the opening mechanism
  • a drinks can or food tin production line including a production station for providing a barrier means to overlie the opening mechanism
  • Figure 1 is a perspective view of a conventional unopened container having a ring-pull mechanism
  • Figure 2 is a perspective view of the container when opened
  • Figure 3 is a perspective view of a first embodiment of a container according to the invention.
  • Figure 4 is a perspective view of a second embodiment of a container according to the invention.
  • Figure 5 is a perspective view of a third embodiment of a container according to the invention.
  • Figure 1 shows a conventional can generally referenced 1 1 in which for example drinks are typically supplied The contents of the can 1 1 are poured out via a hole 12, as shown in Figure 2, at the top of the can 1 1, the hole 12 being sealed for purposes of storage and transit by the sealing tab 13 Attached to the sealing tab
  • Figure 3 shows the can shown in Figure 1 with the sealing tab 13 and the ring-pull
  • the barrier 20 is sealed about its periphery 21 to the top of the can 22 thus isolating the sealing tab 13 and the ring-pull 14 from the environment
  • the barrier 20 is removed and the can opened, by moving the ring-pull 14 to the conventional position as shown in Figure 2 Any dirt or other undesired material which might otherwise accumulate around the ring-pull mechanism is thus removed with the barrier 20, and does not enter the can 11
  • Figure 4 shows an embodiment of the invention in which the barrier 30 extends across the inside surface of the top of the can 32, the barrier 30 again being sealed about its periphery 31 to the can 11
  • Figure 5 shows a yet further embodiment in which the barrier 40 extends across the entire top of the can 1 1 and the barrier 40 is sealed about its periphery 41 to the outside of the can 11
  • the barrier can extend about and fully enclose the container
  • the barrier may comprise score-marks or perforations to allow part of it to be removed, whilst leaving a part remaining attached to the container
  • the barrier can be coated with, or otherwise comprise an indicator which shows either contamination of the lid of the container or that the barrier is not intact
  • an indicator which shows either contamination of the lid of the container or that the barrier is not intact
  • the barrier may also be impregnated or otherwise comprise a disinfectant or antibacterial material to improve hygiene
  • the barrier can be formed from
  • barrier which can be pigmented or is suitable to recei e print
  • Such a barrier can then be employed to display, for example, instructions on container and content usage, manufacturer's details such as date of manufacture, batch number etc
  • the barrier can also be used for advertising purposes and in fact give a greater area to display the advertisement than the top of a container having a conventional ring- pull mechanism as the sealing-tab and ring pull normally restrict the space available
  • the barrier can be sealed to the container by a suitable adhesive
  • the adhesive employed can be sufficiently strong to enable the barrier to be re-sealed into position if only a proportion of the contents has been removed Alternatively or additionally, the barrier can be thermoformed into the desired shape and position about the container
  • a vacuum can be introduced between the barrier and the container to improve hygiene
  • an inert gas can be introduced to maintain a suitable pressure in the space there between
  • the barrier is then sealed to the container by means of for example applied heat or pressure to an appropriately chosen adhesive typically located about the periphery of the barrier.
  • an appropriately chosen adhesive typically located about the periphery of the barrier.
  • the invention is also directed towards a production line including a production station for applying a barrier membrane to overlie the ring-pull mechanisms
  • the barriers as described herein not only serve to prevent dirt from accidentally contacting the contents of the container They can also be used to prevent deliberate poisoning of the contents, in that any poison applied to the barrier would be removed prior to breaking the seal
  • the barrier could also be so constructed for example by vacuum sealing the barrier, or by the use of tear strips, so that it would reveal if any attempt had been made to introduce material under the barrier, for example, by injection

Abstract

Dans cette invention, un contenant (11) pourvu d'un mécanisme classique à onglet comporte un dispositif barrière (20) situé sur le mécanisme à onglet afin d'empêcher la contamination de ce mécanisme avant l'ouverture du contenant (11). Le dispositif barrière (20) peut comprendre une couche adhésive permettant de sceller le dispositif barrière (20) au contenant (11). Le dispositif barrière (20) peut également comprendre des marques ou des perforations permettant de le retirer partiellement ou complètement. En outre, ce contenant peut comporter un indicateur dans/sur la surface du dispositif barrière (20) pour indiquer si le dispositif barrière (20) a été endommagé. Par ailleurs, cette invention concerne un procédé de fabrication d'un contenant, consistant à fixer un matériau barrière sur le mécanisme d'ouverture du contenant.
