Definitions

  • Blow moulded bottles especially those made of clear plastics material which is bi-axially oriented during its blow moulding step are nowadays very popular and widely used. They are especially useful for packaging carbonated beverages and capable of resisting the internal pressure generated by the carbonated beverage. ' Such bottles are also used to contain other liquids ranging from industrial chemicals such as white spirit and methylated spirit to uncarbonated beverages and bottled water.
  • PET polyethylene terephtalate
  • PET polyethylene terephtalate
  • PET has a relatively low permeability which both prevents carbon dioxide escaping from carbonated beverage, prevents permeation by the liquid vapour to allow escape of the contents and prevents the ingress of oxygen which can result in oxidation and spoilage of the bottle contents.
  • Its permeability can be reduced still further by including some form of barrier material having an even lower permeability in the form of a layer by or introducing this material as a blend with the PET or as a laminate.
  • barrier material is expensive and typically 50% cf the manufacturing cost of such a bottle directly results from the material cost of the PET. When barrier materials are included these are typically even more expensive and so increase the material cost still further when blends and laminates are used.
  • the pre-formed shell not only acts as a mould during the blowing of the liner but subsequently goes on to act as an exo-skeleton for the finished bottle to provide the majority of the strength and barrier characteristics for the bottle.
  • the shell can be made from recycled material and, even if this is somehow contaminated the contamination does not reach the contents of the bottle because of the presence of the liner forming a continuous lining throughout the entire inner surface of the bottle.
  • the plastics material to form the liner represents only a small percentage such as 10-20% of the total weight of the plastics material in the bottle and thus it is always possible to use virgin plastics material for a liner and thus ensure that the liner is always clean, sterile and uncontaminated.
  • the bottle is typically returned to the bottle filling station where the existing liner is removed by applying a vacuum to the neck of the bottle to collapse the liner and allow it to be withdrawn from the shell.
  • the shell is then simply relined before being refilled and recirculated.
  • the material from the removed liners may be recycled to produce further shells. Since, in a method in accordance with the present invention the liner is made from a separate preform which is subsequently blown into the shell with the shell acting as a mould during the blowing operation, the bottles can be formed by a very simple blow moulding machine.
  • the machine is so simple that it can be located and form part of the bottle filling plant which considerably enhances the recycling operations.
  • Naturally transport is required to transport the filled bottles from the bottle filling plant to the consumers and the same transport can be used to return empty bottles to the filling plant.
  • Equally, the damaged shells and the used liners can be returned to the manufacturers of the shells and preforms by the same transport used to deliver fresh supplies of preforms and shells.
  • the shell includes vent means to allow venting of air displaced from the inside of the shell during blowing of the liner.
  • the vent means also allows air to enter the space between the inner wall of the shell and the outer wall of the liner as the liner is evacuated to collapse it before the shell is reused.
  • the vent means may be formed by corrugations around the internal wall of the side wall of the shell extending up to the neck of the shell when the liner is expanded from the base towards the top.
  • the vent means may be formed by a hole in the base of the shell and the liner is expanded from the top downwards during its blowing operation.
  • the base of the shell may also include generally radially ' extending valleys in communication with the hole to ensure that the base of the liner is formed correctly.
  • vent means are provided at both the top and bottom of the shell.
  • the centre of the base of an article formed by blow moulding is typically thicker than the side wall of that article. Use can be made of this property by ensuring that the vent in the base of the shell is placed centrally so that, after the liner has been blown into the shell this central thicker region of the liner overlies the vent hole in the base of the shell.
  • This thicker region in the base of the liner may provide sufficient integrity for the whole bottle to compensate for the absence of the shell in the region of the vent hole.
  • the shell may include means to seal the vent before the bottle is filled. These means may have the form of a valve with a closure member which is biased into contact with the base of the shell around the vent to seal it. In this case the valve may be held open during the blowing of the liner and merely allowed to close upon completion of the blowing step, for example, by being closed by the base of the liner.
  • the vent includes a removable plug which is inserted after the liner has been blown and before the bottle is filled and, on recycling, is removed before the liner is removed from the shell.
  • the vent means is formed as an internally screw threaded socket which is fixed to the base of the shell and the plug is screwed into this socket to form a gas tight seal.
  • the shell may be formed by a blow stretch moulding process and, in this, the neck of the shell may be removed after the moulding operation but, preferably, the shell is formed by injection moulding.
  • the inside of the shell may be coated with a release agent to ensure that the liner is does not stick to it.
  • the liner may be made from a material which is chemically similar to that of the shell but which is modified to enable it to be blown without being heated. Typically such materials have a lower intrinsic viscosity and a higher melt flow index. This enables a particularly simple blow moulding machine to be used which requires no heating elements or moulds and this makes it a particularly suitable, machine to be installed at a bottling plant. Whilst such cold blow grades of material are typically different from those used for the shell they are miscible with those used for the shell and can therefore be recycled successfully and reformed into shells.
  • the preform of the liner is injection moulded but, particularly when it is made from a material having a lower intrinsic viscosity it may alternatively be vacuum formed- or thermofor ed.
  • a significant reduction in the injection moulding cycle can be obtained resulting in a greater productivity of the injection moulding machine.
  • the preform for the liner may be made of a conventional bottle grade material and, in this case, the preform is heated before placing it inside the pre-formed bottle shell and blown to provide a continuous liner for the entire inner surface of the bottle.
  • the liner may be blown by a stretch and blow technique or, especially when the liner has a very thin wall thickness, by a simple blow moulding technique.
  • the preform is heated preferably it is differentially heated along its length before it is blown.
  • this portion of the preform is not heated at all whilst the portion of the preform to form the liner of the completed bottle is heated.
  • the portion of the preform to form the liner may itself be -differentially heated to ensure that the preform expands in the required fashion, for example, expands in a direction towards the vent means.
  • the liner and the shell are most likely both to be formed of PET they may be formed from different materials particularly when the finished bottle is required to fulfil a particular function.
  • the liner is formed of polypropylene since it has a higher thermal stability than PET.
  • the shell includes the neck of the finished bottle and, for example includes the male screw thread or other fitting on the neck of the bottle which co-operates with the bottle closure and so the shell provides the basic performance characteristics of the finished bottle then the liner may be formed by a safe but cheap plastics material so that it can be discarded after use. This is particularly useful where the preform for the liner can be cold blown.

  • the outer shell can have a variety of forms as shown in Figures 1 to 8.
  • Figure 1 has the outer shell extending over the entire cylindrical portion and the base of a bottle of generally conventional shape and the liner provides the neck fitting of the bottle and the tapering neck region as well as a lining for all of the shell 1.

  • Figure 10 illustrates the case where the shell 1 includes the neck support ring 3 whilst the liner 2 includes a male screwthread for attachment of the closure.

  • Figure 12 corresponds to the arrangement of the second and third examples where the entire neck region of the finished bottle is formed on the liner 2.
  • Figures 10 to 12 also show in dotted lines the location of venting slots formed on the inside of the shell 1 when the top of the shell 1 requires venting.

  • a plug 10 having a corresponding frusto-conical sealing surface 11 and male screw thread 12 can be screwed into and out of the socket 7 using a splined tool which co-operates with a correspondingly splined hole 13.
  • the method of producing bottles in accordance with this invention requires first that the shells 1 are formed by injection moulding or stretch blow moulding and have the sockets 7 spin welded to hole 6 formed in their base.
  • a preform to form the liner is injection moulded and, where the liner is to include a neck fitting with screw threads, or interlocking features for use with a bottle closure, and a neck support ring 3, this is also typically formed as part of the injection moulded preform.
  • the shells 1, plugs 10 and preforms for the liner are shipped separately to a bottle filling plant. As part of the processes carried out at the bottle filling plant the preforms for the liner are placed on a heated mandrel or corepin.
  • the mandrel does not heat the neck region of the preform but heats the portion of the preform that is to be blown to form the liner 2. This ensures the integrity of the injection moulded sections which form a seal with the closure.
  • the heated preform is then placed inside the shell 1, as shown in Figure 16, which is either a newly manufactured shell or is a shell which is being reused after having been returned. Alternatively, the preform may be heated after being placed inside the shell 1.
  • the preform is then blown to provide the liner 2 with the shell 1 acting as the blowing mould.
  • the plug 10 Upon completion of the blowing step the plug 10 is screwed into the socket 7 to complete the bottle.
  • the bottle is then rinsed, filled and has a conventional closure applied to its neck.
  • the bottle is then sold at a price including a deposit.
  • After the contents of the bottle have been consumed the bottle can be returned and the deposit reclaimed.
  • the returned bottles are returned to the bottle filling plant where the plugs 10 are unscrewed, either to be reused or to be discarded, and a vacuum is applied to the neck of the liner. This collapses the liner with air being drawn in through the hole 6 and via the radially extending valleys 5 until the liner can be removed from the shell 1.
  • the removed used liners are returned to the shell maker to be granulated and reprocessed tc be made into further shells.
  • the now empty shell is returned to the bottle blowing machine to have a new liner fitted before it is refilled.
  • the shell includes a barrier layer of highly impermeable material to enable it to be formed with a lightweight yet still have the required degree of impermeability.

Abstract

Procédé pour fabriquer une bouteille en plastique, comprenant une enveloppe de bouteille (1) et une doublure (2). Ce procédé comprend les étapes de fabrication d'une préforme, la mise en place de celle-ci à l'intérieur d'une enveloppe de bouteille préformée (1) et le soufflage de la préforme en se servant de l'enveloppe de la bouteille (1) comme d'un moule pour donner une doublure continue (2) à toute la surface interne de la bouteille. L'enveloppe préformée (1) agit non seulement comme un moule au cours du soufflage de la doublure mais elle poursuit son action en tant que squelette externe de la bouteille terminée afin de fournir la majeure partie des caractéristiques de résistance et d'isolation de la bouteille. Cette technique permet de doubler à nouveau l'enveloppe et de l'utiliser de manière successive sans aucun risque de contamination. L'enveloppe peut être réalisée en matériau recyclé.
