Definitions

  • This invention relates generally to a package or container unit for containing fluid or possibly a mass product and being adapted to the demands of today and the future for resource saving and environmentally lenient distribution and return systems.
  • the package unit is particularly in the form of an inner liner container or bottle having a cap, the liner forming an inner recipient acting as a flexible bag.
  • the unit is price competitive within systems based upon resource saving, recycling and/or reuse and is further well adapted to suit already existing tapping and distribution systems for fluid or products in mass or bulk form.
  • the system according to the invention will be competitive by distri ⁇ bution of liquid milk products, beverages, water and possibly beer, as well as detergents, pharmaceutical products, chemicals, nutrition agents, pesticides, products for agriculture etc.
  • a survey of the environmental profile of a package system will give the basis for comparing different alternatives with respect to their influence upon and focus on particularly harmful effects on the environment during the life cycle of the package, so as to effectuate improvements.
  • Survey models and reports of this type are also a valuable aid for a factory to chose a package system by also considering environment relations.
  • models of this kind often have strong limitations, i.a. the total amount of disposal may be considered without taking into account local strains or impacts on nature/environment, and the models also mainly concern the outer environment, only to a less degree the inner environment in the form of working milieu around or related to the consumer. Under or connected to the working milieu also the problems facing employment and domicile establish ⁇ ment must be looked at, and it is to be understood that a well established industry that is manufacturing certain package types and maybe having important market shears will feel it necessary to fight to protect the existing market pattern even if national or global aspects should indicate other solutions. (See for example articles in the daily press on strike threaths to defend the envir- onment tax on aluminium boxes and on brewery worker's strike in October 1991. )
  • the transport contribution to the environment impact in the recycle case is usuallyconsiderably lower, even at long transport spans, compared to the first process steps in the non-returnable case.
  • Different levels of recycling may be actual, but generally the rule is that the environmental benefits are reduced approximately proportional to the decrease of the recycling level.
  • the present invention in fact offers a solution to several of these problems by being precisely related to a package, enclosure or recipient device that turns out advantageously in relation to points 1) - 4) above.
  • the form of the container or enclosing bottle is chosen so that storing and piling may be effectuated easily and space saving, and the materials for both the bottle, its lid or cap and inner liner are chosen to facilitate reuse/final destruction with recycling of the material.
  • the container may i.a. be designed to be used again and again some tens to hundreds of times before it is brought to decom ⁇ position and reproduction, while the inner liner may be destructed after use only once, or even the liner may be used several times after cleaning and inspection. Even the cap is prepared for an 5 effective recycling due to its design.
  • a container device comprising an outer container, a cap and an inner liner, said elements being particularly of the kind disclosed in the following patent claims.
  • Preparation here is to be understood as closing, 5 cutting off, insertion, securing and sealing of the liner, filling the inserted liner with the fluid of interest, closing of the con ⁇ tainer and transport for the final distribution.
  • the preparation also comprises a possible preceding removal of a liner from a container in return and cleaning and inspection of same.

  • Fig. IB shows from above the container and its neck portion 4 in its rib version, said ribs 8 forming lengths that cover a peripheral angle approximately 45° and interrupted by correspondingly long recesses 11. Being formed o in this way, the neck portion allows a tightly sealing securing of the cap 3 via an inserted double foil of blank material and without the necessity of more than a maximum of 67,5° rotation.
  • Fig.1C indicates that the neck portion 4 of the container or bottle may be tapered towards the entry opening 6 and in this 5 case the ribs 8 or grooves 10' then would have a helically and possibly intermittent configuration on the outer side of the neck portion.

  • This form is suitable for space saving by transport and storing.
  • Circular containers or bottles may, however, be suitable due to production reasons and it must be considered what is most important of the following parameters: transport volume and costs, storing conditions or the costs of manufacture.
  • a system having polygonal bottles for certain appli ⁇ cations may be actual, for example could bottles with circular cross-section be specified for milk, while bottles having rect- angular shape could be specified for juice etc., further a such system could incorporate the use of hexagonal bottles for deter ⁇ gents, cleaning agents and the like, while octagonal bottles could be used entirely for pharmaceutical products and chemicals.

Thereafter the part of the liner on the outer side of o the neck portion is heat welded, and then the bottle is prepared for filling of the product in request. In the next step of this part of the process an ascending air stream is directed towards the bottle so that the hanging skirt 26 is blowed upwards.

  • the cap may 0 separately be subject to a deposit system to prevent that the cap material contributes to littering and for saving resources by allowing destruction by melting and reuse.
  • the return bottle machines of today are well adapted to distinguish between different bottle types, included bottles with or without a recognizable cap, 5 and in this way a larger deposit amount may be returned by the return of a complete bottle, compared to returning the bottle without its cap.

  • the upper part of the side portion 78 therefore must be pressed further downwards which leads to a deformation of the upper part of the base portion 75 in the region of the lower connection area 81, which establishes a better locking of the support ring 76 in the lower retaining groove 77' .

  • a rib and/or a groove may be arranged additionally on the inside to keep the inner cap in a certain position within the cassette.
  • the bottle or container on which the cap shall be mounted has some kind of a guiding element it will be possible to secure that both the mounting cassette and the inner cap is mounted onto the bottle in an unambiguous way, which may be advan ⁇ tageous due to different reasons, for example regarding the sealing of the cap, correspondence between legends on the cap and t e bottle, bottles with non-circular neck portion will be allowed, etc.
  • the mounting cassette after the filling of the bottle is removed, i.e. returned to the process for introduction of a new inner cap.
  • the upper sealing foil 114 of the mounting cassette may be kept intact by removing the cassette before the filling, or the filling may be done by puncturing of the upper foil in the same way as for the previously described embodiments.
  • the cassette thereafter will be removed after the filling is completed and the filler device withdrawn.
  • the embodiments of the cap having a protruding support ring 76, 117 are advantageous due to a better adaptability for automatic mass production and versatility together with different bottle types.
  • the cap according to the invention has in a particular embodiment on its lower part a base portion formed like a collar to facilitate and secure a reliable connection to the edge of the inner liner, this connection preferably also may be automatically in the actual production machines. Support and guiding of bottles s having no inherent protruding collar thereby may take place with the aid of the collar in the base portion of the cap.
  • the securing of the liner to the support ring 76, 117 (at 118) may be effectuated by conventional adhesive technique, for example by using two-component glue.
  • the first o glue component is provided on a ring innermost and outermost on the upwardly directing surface of the support ring, possibly also over the complete surface.
  • the provision of glue over two rings will particularly be practical when the support ring has holes or recesses in the middle portion.
  • the support ring may be extended down ⁇ wardly in the way illustrated in Fig. 13B. Thereby a greater stability is obtained against distortions at full charge, i.e.
  • the cap according to the invention and having a support ring therefore gives opportunity to a better quiding of bottles having no such supporting collar in the neck portion, a stable handling of bottles with or without supporting collar due to that 5 the support ring of the cap in addition is provided with a down ⁇ wardly extending supporting part, and excellent utilization of an existing bottle park without the necessity to change the form of the bottles, since bottle with accompanying cap may directly suit existing and future return deposit systems.

Abstract

Un récipient obturable destiné à un fluide ou à du vrac peut être produit automatiquement en série et comprend des composants entièrement réutilisables, récupérables et/ou décomposables. Il comporte pour l'essentiel: un récipient ou une bouteille (1, 71) à large col (4, 74), un bouchon (3, 73, 111) et un garnissage interne étanche aux fluides (2, 72) réalisé en matière thermoplastique et, de préférence, thermorétrécissable et décomposable par les ultraviolets. Le récipient (1, 71) lui-même n'est pas étanche aux fluides mais comporte un évent d'aération (12, 14) et sert plutôt de module d'emballage réutilisable disposé autour de son garnissage intérieur. Au départ, ce garnissage (72) est de préférence obturé et plié dans le bouchon (73, 111) et il est introduit dans le récipient pendant la production en série de ce dernier dans une installation de fabrication. Ce récipient est destiné à être réutilisé un grand nombre de fois avant destruction ou récupération, alors que le garnissage intérieur peut être détruit après une seule utilisation ou être réutilisé après nettoyage et inspection. La partie inférieure du bouchon comporte une bague de verrouillage ou de support (76, 117) qui peut présenter un collier faisant saillie. Ce récipient peut s'utiliser tant pour des liquides que pour une masse en poudre et respecte les exigences écologiques les plus sévères.
