Definitions

• the invention relates to a package including a container filled to a predetermined level with material such as fluids and to a method of packaging such containers.
• containers such as bottles are fabricated of glass or other material which is capable of holding liquid.
• plastic bottles or containers are used, it is a requirement of health authorities that the plastic fabrication material be of a
• plastics material will not allow liquid to seep therethrough or extraction of plastic components into the containers contents but commonly permit gases to permeate through the material to the contents of' the container. Where the material contained in such plastic containers are subject to spoilage or other contamination if exposed to oxygen, it is common to either designate the product as having a short shelf life or resort to different materials such as glass or metal or special and expensive grades of plastics material.
• the laminate usually comprises an approved food grade plastics inner lining of, for example, polyethylene and an integrally formed outer layer of non-food grade plastics material which prevents gas permeating through it to contact the liquid inside the container.
• These laminates have to be specially prepared which considerably adds to the cost of fabrication and resultant cost of the container.
• the prime purpose of the container is to merely provide a vehicle for carrying the material, the liquid being the saleable commodity, it is always desirable to minimise the cost of the container.
• gas permeable plastic container material is unsuitable as carbonation gases, usually carbon dioxide, will permeate through this material and cause the liquid to return to its non-carbonated or flat form.
• the invention proposes a package and method of packaging which substantially prevents gases permeating into or from a container made of plastics material thereby enabling the weight advantages of plastics material to be utilised.
• a package comprising a container of plastics material and a film of plastics material having low gas permeability and encasing the container.
• the container is fabricated either wholly or in part with plastics material which does not exhibit low gas permeability.
• plastics material which does not exhibit low gas permeability.
• plastics material which does not exhibit low gas permeability.
• P.E.T. polyethyleneterephthalate
• these materials are used in soft drink, milk and aerated waters containers where the life of the beverage is not effected by the gas permeable quality of the material.
• the thickness of the plastics usually ranges from 0.3 to 1mm.
• the plastics film is a nylon based material such as nylon 6.
• nylon based material such as nylon 6.
• Other plastics materials will be well known to those skilled in the art which material has low gas (especially oxygen ) permeability.
• the plastics material film may be applied continuous all over the outer surface of the plastics material of the container.
• this film can be applied to the container by either evacuating the space between the film and the plastic container or by the well known process of shrinkwrapping.
• the film may be applied by any suitable methods and the invention is not limited to any one particular method.
• the container is separated from the film by an atmosphere which is inert to the material held in the container. Where the material is a carbonated beverage, the interposing atmosphere may conveniently be carbon dioxide thereby reinforcing the carbonation of the beverage. Nitrogen gas is another example of such an inert atmosphere.
• the package may incorporate a cup.
• a cup is inverted and placed over the neck of the container prior to the film being applied to the container.
• the cup may include a portion which can act as an integral seal for the container.
• One method of achieving this is for the cup in the portion aforementioned to be internally threaded which threads engage external threads on the top of the container. By turning the cup relative to the container the seal is engaged.
• the portion preferably also has a central annulus which will project into the opening of the container and form a secondary seal against the inside surface of the container immediately adjacent to the opening.
• This composite package is particularly useful in the travel industry in which separate handling and provision of a container of liquid and a cup is normal. It will be readily appreciated that the shape of the container and the cup may be varied, and that such variations do not depart from the spirit of the invention.
• a method of packaging which comprises the steps of:
• the plastics film is continuous and is subjected to heat shrinking to encase the plastics container.
• the area between the continuous film and plastics container is evacuated and the film seals all surfaces of the plastic container from the surrounding atmosphere.
• the area between the plastics film and the plastics container may be filled with a gas which is inert to the material held in the container. For example, carbon dioxide would be considered inert to carbonated liquid and in fact this atmosphere would serve to reinforce the carbonation of the liquid.

• Container 1 is made of food grade plastics material such as polyethylene and has a neck 2 having an opening destined to be sealed by a closure . Container 1 may be filled with material to any predetermined level prior to applying the closure.
• a drinking cup 3 which includes a cup portion 9, a stem 10 and a base 4.
• the base 4 has a square profile 5 and a recess 6.
• the composite package as more clearly shown in Figs.8 & 9 is easily stacked and is prevented from rolling.
• Reference to Fig.5 illustrates how annulus 11, annular rib 13 and neck 2 of the container interact.
• the container 1 and drinking cup 3 has applied to its outer surface a film 14 of plastic material which has low gas permeability.
• This film 14 may be applied to the outer surface of the package by heat shrinking the film 5 or by evacuating the space which would initially form between film 14 and container 1.
• film 15 which is also of plastics material having low permeability, surrounds container 1.
• the space 16 between the container 1 and film 15 is either evacuated or filled with an oxygen free gas which is inert to the material in container 1, for example carbon dioxide. Accordingly, air cannot permeate through film 15 and into container 1 thereby safeguarding the material in containerl.
• the invention therefore presents a simple package and packaging technique which utilises a combination of the desirable properties of different types of plastics material.
• plastics material In view of the light weight nature of plastics material, such packaging is particularly suited for packaging wine and other beverages for aircraft use in which minimizing of weight is of prime concern. Also for packaging materials in plastic to the exclusion or inclusion of desirable or undesirable gases.
