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 different materials. It also relates to a method for producing the 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 are—produced 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, JPA-10128833, 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.
  • 6,238,201 a method is described including co-extruding a two layer parison followed by blow-moulding said parison into a bag-in-container wherein the outer layer preferably comprises an olefin and the inner layer an amorphous polyamide.
  • the heating rate of the two layers can be substantially different due to the wide difference in thicknesses between the inner and outer layers.
  • the inner layer is sheltered by the thick, outer layer from the IR-radiation of the IR-oven usually used to bring the preform to blow-moulding temperature. It follows that even for materials having little or no difference in blow-moulding temperature, there can be a problem to heat up simultaneously both layers to their process temperatures.
  • the different preform components may be heated separately in different ovens to heat them at their respective blow-moulding temperature (cf. e.g., JPA57174221).
  • This solution is expensive in terms of equipment and space and does not apply to integral preforms, which inner and outer layers cannot be separated.
  • blow-moulded co-layer containers i.e., not meant to delaminate
  • energy absorbing additives has also been proposed in the inner layer of blow-moulded co-layer containers (i.e., not meant to delaminate) to compensate for the greater strain undergone by the inner layer compared with the outer layer during blow-moulding operation.
  • co-layer containers it is very important that the inner layer is allowed to stretch sufficiently to contact and adhere to the outer layer over substantially the whole of their interface.
  • the inner layer containing the energy absorbing additives is thus heated to a higher temperature than the outer layer and can be stretched further to adhere to the outer layer.
  • 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 preforms as well, which are characterized by an outer layer being substantially thicker than the inner layer. This has a detrimental effect on the heating efficacy of IR-lamps on heating the inner layer, since the latter is separated from the IR-lamps by the thick wall of the outer layer.
  • the present invention relates to a preform for blow-moulding a bag-in-container.
  • An inner layer and an outer layer are used, wherein said preform forms a two layer container upon blow-moulding, and wherein the obtained inner layer of the container releases from the thus obtained outer layer upon introduction of a gas at a point of interface between said two layers.
  • At least one of the inner and outer layers includes at least one additive allowing both inner and outer layers to reach their respective blow-moulding temperatures substantially simultaneously when heated together in a single oven.
  • the present invention relates to the use of energy absorbing additives for the substantially simultaneous heating to the respective blow-moulding temperatures of the inner and outer layers of a preform for blow-moulding a bag-in-container.
  • 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 consists 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.
  • a preform for the production of a typical 8 liter bag-in-container for dispensing beer has an outer layer ( 12 ) about 210 mm thick, preferably 36 mm, most preferably 45 mm thick, whilst the inner layer generally is about 0.33 mm thick, preferably 0.31.5 mm, most preferably 0.51 mm thick
  • Preferred materials for the inner and outer layers of the preform and bag-in-container of the present invention are pairs of different materials selected from the group of 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.
  • Materials like PET or PEN should optimally be heated before blow-moulding, whilst polyolefins and polyamides should be heated.
  • energy absorbing additives are added to the resin having highest process temperature. It is, however, also possible that both layers comprise energy absorbing additives of different nature and/or in different amounts, as long as the time required to arrive at the respective process temperatures of the materials of the inner and outer layers is substantially the same.
  • the additives useful in the present invention may be any compound that selectively absorbs radiation in the wavelength region of 500 to 2000 nm and which is preferably sufficiently fine not to be visible to the eye. They comprise energy absorbing additives and colorants. Examples of energy absorbing additives include but are not limited to carbon black, graphite, diamond dust, diazonium salts, sulphonium salts (e.g., triphenylsulphonium bromide), sulfoxonium salts, odonium salts, etc.
  • the amount of additive present in a layer depends on the additive itself and on the resins used for the inner and outer layers. A larger amount may impair stretchability of the layers.
  • 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. 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 ).
  • 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, at least one layer of which comprising energy absorbing additives; bringing each layer of said preform to their respective blow-moulding temperatures; 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, wherein, the type and amount of energy absorbing additives comprised in at least one of the inner and outer layers of said preform are such that said two layers reach their respective blow-moulding temperatures substantially simultaneously.
  • 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 pressure-time-temperature window used is of course of prime importance and greatly depends on the materials 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.
  • Preforms comprising an inner and outer layers made of different materials were heated in an oven comprising six IR lamps. The heating conditions were maintained constant for all the tests. The temperatures, T inner and T outer , of the inner and outer layers were measured after residence in the oven and the preforms were then blow-moulded with a blow pressure of 10 bar in a mould set a temperature of 83° C. Table 1 below lists the measured temperatures of the inner and outer layers, comments on blow-mouldability, and indicates the values of the delamination pressure.
  • the delamination pressure was determined as follows. The interface vents of an empty bag-in-container obtained as described above are connected to a source of pressurized air. Air is injected through the vents at a constant pressure and the interface between inner and outer layers is observed; the pressure is increased until delamination pressure is 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 are examined for traces of bonding. Preferred results are a low delamination pressure, of the order of above 0.3 to 0.9 bar overpressure, with no traces of bonding.
