Definitions

  • the present invention relates in general to new developments in dispensing bag-in-containers and, in particular, to integrally blow-moulded bag-in-containers made of a single material. It also relates to a method for producing said bag-in-containers and, in particular, to preforms used for their production, as well as a method for producing said preform.
  • Bag-in-containers also referred to as bag-in-bottles or bag-in-boxes depending on the geometry of the outer vessel, all terms considered herein as being comprised within the meaning of the term bag-in-container, are a family of liquid dispensing packaging consisting of an outer container comprising an opening to the atmosphere—the mouth—and which contains a collapsible inner bag joined to said container and opening to the atmosphere at the region of said mouth.
  • the system must comprise at least one vent fluidly connecting the atmosphere to the region between the inner bag and the outer container in order to control the pressure in said region to squeeze the inner bag and thus dispense the liquid contained therein.
  • bag-in-containers were and still areproduced by independently producing an inner bag provided with a specific neck closure assembly and a structural container (usually in the form of a bottle).
  • the bag is inserted into the fully formed bottle opening and fixed thereto by means of the neck closure assembly, which comprises one opening to the interior of the bag and vents fluidly connecting the space between bag and bottle to the atmosphere; examples of such constructions can be found inter alia in U.S. Pat. No. 3,484,011, U.S. Pat. No. 3,450,254, U.S. Pat. No. 4,330,066, and U.S. Pat. No. 4,892,230.
  • These types of bag-in-containers have the advantage of being reusable, but they are very expensive and labour-intensive to produce.
  • the multilayer preform may be extruded or injection moulded (cf. U.S. Pat. No. 6,238,201, JPA10128833, JPA11010719, JPA9208688, U.S. Pat. No. 6,649,121).
  • the former method is advantageous in terms of productivity, the latter is preferable when wall thickness accuracy is required, typically in containers for dispensing beverage.
  • Preforms for the production of integrally blow-moulded bag-in-containers clearly differ from preforms for the production of blow-moulded co-layered containers, wherein the various layers of the container are not meant to delaminate, in the thickness of the layers.
  • a bag-in-container is comprised of an outer structural envelope containing a flexible, collapsible bag. It follows that the outer layer of the container is substantially thicker than the inner bag. This same relationship can of course be found in the preform as well, which are characterized by an inner layer being substantially thinner than the outer layer. Moreover, in some cases, the preform already comprised vents which are never present in preforms for the production of colayered containers (cf. EPA1356915).
  • the melting temperature of the outer layer should be higher than the one of the inner layer in order to allow production of integral preforms by injection moulding the outer layer thereof, followed by injecting thereover the inner layer.
  • materials for the outer layer given by the authors include PET and EVOH, whilst polyethylene is given as an example for the inner layer. Though this materials selection could be advantageous for the injection moulding production of the preforms, it is far from optimal for the blow-moulding step since polyethylene and PET are characterized by different blow-moulding temperatures.
  • 6,238,201 a method is described including coextruding a two layer parison followed by blow-moulding the parison into a bag-in-container wherein the outer layer preferably comprised an olefin and the inner layer an amorphous polyamide.
  • the present invention is defined in the appended independent claims. Preferred embodiments are defined in the dependent claims.
  • the present invention relates to an integrally blow-moulded bag-in-container wherein the same polymer is in contact on either side of the interface between the inner and outer layers.
  • preform for blow-moulding a bag-in-container having an inner layer and an outer layer, wherein the preform forms a two-layer container upon blow-moulding, and wherein the thus obtained inner layer of the container releases from the thus obtained outer layer upon introduction of a gas at a point of interface between the two layers.
  • the inner and outer layers are the same material.
  • a preferred embodiment the preform according to the present invention is an assembly having a first preform for the inner layer, and a second preform for the outer layer such that the first preform fits into the second preform.
  • the preform is an integral preform obtained by injection moulding one layer over the other.
  • FIG. 1A is a schematic cross-sectional representation of a first embodiment of a preform according to the present invention and the bag-in-container obtained after blow-moulding thereof.
  • FIG. 1B is a schematic cross-sectional representation of a second embodiment of a preform according to the present invention and the bag-in-container obtained after blow-moulding thereof.
  • FIGS. 1A and 1B there is illustrated an integrally blow-moulded bag-in-container ( 2 ) and a preform ( 1 )&( 1 ′) for its manufacturing.
  • the preform ( 1 ) comprises an inner layer ( 11 ) and an outer layer ( 12 ) joined at least at the level of the neck region ( 6 ) by an interface (shown on the right hand side).
  • the region between inner and outer layers ( 11 ) and ( 12 ) may either consist of an interface ( 14 ) wherein the two layers are substantially contacting each other, or comprise a gap ( 14 ′) in fluid communication with at least one vent ( 3 ) opening to the atmosphere in ( 4 ).
  • vent geometries have been disclosed and it is not critical which geometry is selected. It is preferred, however, that the vent be located adjacent to, and oriented coaxially with said preform's mouth ( 5 ) as illustrated in FIG. 1 . More preferably, the vents have the shape of a wedge with the broad side at the level of the opening ( 4 ) thereof and getting thinner as it penetrates deeper into the vessel, until the two layers meet to form an interface ( 14 ) at least at the level of the neck region.
  • This geometry allows for a more efficient and reproducible delamination of the inner bag upon use of the bag-in-container.
  • the container may comprise one or several vents evenly distributed around the lip of the bag-in-container's mouth.
  • vents are advantageous as they permit the interface of the inner and outer layers ( 21 ) and ( 22 ) of the bag-in-container ( 2 ) to release more evenly upon blowing pressurized gas through said vents.
  • the preform comprises two vents opening at the vessel's mouth lip at diametrically opposed positions. More preferably, three, and most preferably, at least four vents open at regular intervals of the mouth lip.
  • the preform may consist of an assembly of two separate preforms ( 11 ) and ( 12 ) produced independently from one another and thereafter assembled such that the inner preform ( 11 ) fits into the outer preform ( 12 ).
  • This solution allows for greater freedom in the design of the neck and vents.
  • it can be an integral preform obtained by injection moulding one layer on top of the other.
  • the latter embodiment is advantageous over the assembled preform in that it comprises no assembly step and one production station only is required for the preform fabrication.
  • the design of the vents in particular is restricted by this process.
  • Preferred materials for the layers of the preform and bag-in-container of the present invention are polyesters like PET, PEN, PTT, PTN; polyamides like PA6, PA66, PA11, PA12; polyolefins like PE, PP; EVOH; biodegradable polymers like polyglycol acetate (PGAc), Polylactic acid (PLA); and copolymers and blends thereof.
  • the two layers ( 11 ) and ( 12 ) of the preform may be connected by an interface ( 14 ) throughout substantially the whole inner surface of the outer layer (cf. ( 1 ) in FIG. 1A ). Inversely, they may be separated over a substantial area of the preform's body by a gap ( 14 ′) containing air and which is in fluid communication with at least one interface vent ( 3 ) (cf. ( 1 ′) in FIG. 1B ).
  • the latter embodiment is easier to realize when using a preform assembly designed such that the inner preform is firmly fixed to the outer preform at the neck region ( 6 ) and a substantial gap ( 14 ) may thus be formed between inner and outer layers ( 11 ) and ( 12 ).
  • the bag-in-container ( 2 ) of the present invention can be obtained by providing a preform as described above; bringing said preform to blow-moulding temperature; fixing the thus heated preform at the level of the neck region with fixing means in the blow-moulding tool; and blow-moulding the thus heated preform to form a bag-in-container.
  • the inner and outer layers ( 21 ) and ( 22 ) of the thus obtained bag-in-container are connected to one another by an interface ( 24 ) over substantially the whole of the inner surface of the outer layer.
  • Said interface ( 24 ) is in fluid communication with the atmosphere through the vents ( 3 ), which maintained their original geometry through the blow-moulding process since the neck region of the preform where the vents are located is held firm by the fixing means and is not stretched during blowing.
  • the interface ( 24 ) between inner and outer layers ( 21 ) and ( 22 ) releases upon blowing pressurized gas through the vents in a consistent and reproducible manner.
  • the success of said operation depends on a number of parameters, in particular, on the interfacial adhesive strength, the number, geometry, and distribution of the vents, and on the pressure of the gas injected.
  • the interfacial strength is of course a key issue and can be modulated by the choice of the material for the inner and outer layers, and by the process parameters during blow-moulding; the pressuretimetemperature window used is of course of prime importance and greatly depends on the material selected for the inner and outer layers.
  • the inner layer is prevented from entering into contact with the outer layer by the air cushion enclosed within the gap separating the two layers when their respective temperatures are the highest.
  • the gap becomes thinner and air pressure within the gap increases.
  • the valve closing the vent opening releases, the air is ejected, and the inner layer is permitted to contact the outer layer and form an interface therewith at a stage where their respective temperatures have dropped to a level where adhesion between the layers cannot build up to any substantial level.
  • a preform according to the present invention was produced by injecting a melt into a first mould cavity to form the preform's inner layer ( 11 ). A melt was injected into a second mould cavity cooled to form the preform's outer layer ( 12 ). The two preform components were assembled to form a preform according to the present invention.
  • the preform produced as explained above was heated in an oven comprising an array of IR-lamps and then fixed into a blow-moulding mould which walls were maintained at a desired temperature. Air was blown into the preform under pressure.
  • the thus produced bag-in-container was then filled with a liquid and connected to an appliance for dispensing beverage comprising a source of compressed air in order to determine the delamination pressure.
  • the delamination pressure was determined as follows. The interface vents of said bag-in-container were connected to the source of compressed air. Air was injected through the vents at a constant pressure and the interface between inner and outer layers was observed; the pressure was increased stepwise until delamination pressure was reached. Delamination pressure is defined as the pressure at which the inner bag separates from the outer layer over the whole of their interface and collapses. The surfaces of the thus separated layers were examined for traces of bonding.
  • the delamination pressure of the bag-in-container described above was of about 05 ⁇ 0.1 bar overpressure and showed little trace of cohesive fracture between the inner and outer layers. This example demonstrates that bag-in-containers of excellent quality can be produced with integral preforms according to the present invention.
