Definitions

  • Blow moulded bottles made of clear plastics material which is bi-axially oriented during its blow moulding step are particularly attractive for packaging foodstuffs.
  • Such bottles are usually made of PET
  • PET has a glass transition temperature of around 70 to 75°C in its amorphous state but this increases to between 160 and 180°C once it is bi-axially oriented.
  • the neck region of the container and the centre of the base panel is in its amorphous state since this region is not bi-axially stretched during the blow moulding step whereas the remainder of the container is bi-axially oriented as a result of being bi-axially stretched during the blow moulding step.
  • a plastics bottle filled with contents which require pasteurisation includes a re-sealable snap-on cap of plastics material covering a primary aluminium foil based seal which forms an hermetic seal with with the top rim of the bottle neck.
  • a snap-on cap type closure provides a perfectly satisfactory secondary seal even though it probably would not be sufficiently reliable to withstand long term storage if that was the only seal provided.
  • a snap-on type seal also has a very much greater tolerance than a typical screw threaded type closure and thus this press-on cap also accommodates distortion in the neck fitting caused by hot filling.
  • the aluminium foil based primary seal provides a greater degree of security against suck back of cooling liquid used to cool hot filled bottles after they have been sealed than does a conventional screw type closure and also, as a result of the semi-vacum that is formed inside the bottle on cooling of its hot contents the primary aluminium foil based seal is, at least to some extent, pulled downwards into the inside of the bottle.
  • the aluminium foil based seal is formed by a laminate of aluminium foil and plastics material and preferably the plastics material is the same as that from which the bottle is formed. This facilitates the heat sealing or ultrasonic welding of the aluminium foil based seal to the top rim of the neck of the bottle.
  • the aluminium foil based seal can be adhered to the top rim of the neck of the bottle using an adhesive.
  • An aluminium foil based seal is substantially impermeable and thus provides a more impermeable closure than many closures made from plastics material.
  • the aluminium foil also acts a pilfer evident barrier. Further methods of showing that tampering has taken place are possible such as the inclusion of a thermal strip which indicates a secondary heat application.
  • the aluminium foil based seal includes a tab projecting outwards from its seal with the top rim of the bottle neck to enable the seal to be grasped easily by the user and ripped off.
  • the snap-on cap of plastics material may be a standard press-on cap such as that sold under the trade name of J Cap made by Johnson and Jorgensen.
  • the cap may also include a pilfer proof feature including a tear off neck band which has to be torn off before the snap-off cap can be removed from the neck of the bottle.
  • a standard snap-on cap is modified to have a much deeper cap so that it will accommodate the depending tab formed on the aluminium foil based primary seal.
  • the bottle is made from PET but, instead, it may be made from polystyrene, or SAN (styrene acrylonitrile) .
  • the material is transparent and crystal clear so that the foodstuff contained within the bottle can be seen clearly.
  • a bottle in accordance with this invention comprises a bottle 1 made by a stretch blow moulding process from PET having a neck 2 with a neck support ring 3 and annular projections 4 and 5 to receive a pilfer-proof ring and press-on cap, respectively.
  • the neck is arranged to receive a 38mm press-on cap.
  • the neck 2 includes a top rim 6 on which is heat sealed to a flexible aluminium PET laminate foil seal 7.
  • the foil seal 7 includes a projecting tab 9 to enable it easily to be gripped and ripped off by the eventual user. To accommodate this the height of the snap-off lid portion
  • the bottle is initially hot filled with, for example fruit juice and then the aluminium foil seal 7 is heat sealed onto the top rim 6 of the neck 2.
  • the bottle is then subjected to a post-filling pasteurisation step followed by cooling, typically using water jets to cool the fruit juice to room temperature.
  • the production line may include a device arranged to measure the concavity of the foil seal 7 to ensure that an hermetic seal has been formed between the seal and the top rim of the neck 2 of the bottle 1.
  • the press-on cap and pilfer-proof ring assembly 8 is pushed downwards onto the neck of the bottle.
  • the press-on cap 7 is then used to re-close the bottle 1 to prevent spoilage or spillage of its contents.
  • the foil seal 7 may be overprinted with brand identification or, for example to be used as a token in a sales promotion.

Abstract

Les bouteilles moulées par soufflage réalisées en matière plastique transparente, matériau qui se trouve orienté de manière bi-axiale au cours de la phase de moulage par soufflage, sont tout particulièrement intéressantes pour conditionner des produits alimentaires. Il existe cependant des problèmes lorsqu'il s'agit de les utiliser pour conditionner un produit alimentaire qui nécessite d'être pasteurisé soit après son conditionnement soit immédiatement avant d'être introduit dans la bouteille. Dans ce cas précis, la bouteille et plus spécifiquement la partie du goulot se déforme et ceci entraîne des problèmes d'étanchéité. On a résolu ce type de problème en équipant la bouteille en plastique (1) d'une capsule à encliqueter à refermeture hermétique (8), réalisée en matière plastique, qui sert à couvrir un premier joint fait d'une feuille d'aluminium (7) qui permet une fermeture hermétique avec le rebord supérieur (6) du goulot (2) de la bouteille. L'utilisation de deux systèmes de fermeture distincts résout tous les problèmes exposés ci-avant.
