DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to improvements to packaging and more particularly but not exclusively, the present invention relates to packaging and packaging handling apparatus for bulk materials such as powdered or granulated material including milk powder. However it is to be appreciated that the present invention has application wherever any material is required to be packaged.
In the case of bulk material such as milk powder, various forms of packages have been proposed which will facilitate the packages being filled, transported, and subsequently emptied. In the case of a food product such as a milk powder there needs of course to be the observance of strict hygiene requirements and various complex packages have been proposed which will eliminate or at least substantially minimise the chance of contamination of the food product. In such instances an inevitable result has been a package of complexity and attendant costs which is also typically difficult to use. In practice, it can require the sealing and unsealing of various layers which avoid dust, dirt or other contaminants and including human contact, from contaminating the contained product.
In the packaging of bulk materials, there have also been various proposals which will facilitate the packaging, storage and transport of large quantities of material in various forms of containers. One such proposal is the subject of various patents such as New Zealand patent 233690 relating to what is known as the GAMBO (trade mark) bag which by its construction enables a substantially square shape to be retained even after the bag has been filled.
The present invention has particular application to its use with a GAMBO bag but those skilled in the engineering and the packaging arts will appreciate that the present invention will find application in improving the packaging and handling of numerous other types of packaging including but not limited to large plastic bags of the GAMBO type.
It is thus an object of the present invention to provide a packaging means and/or method which will overcome or at least obviate disadvantages in presently available packaging or at least will provide the public with a useful choice.
Further objects of this invention will become apparent from the following description.
BRIEF SUMMARY OF THE INVENTION
According to one aspect of the present invention there is provided a lifting harness for a container comprising a base portion adapted in use to be positionable about a base of the container, said base portion being provided with, or being capable of being provided with, an outlet means through which material contained in said container can exit as it is discharged through said container base, a plurality of lifting means each having free ends adapted to be securable in use, with a suspension means, said lifting means being adapted to be, in use, connectable with an upper portion of said container to position said lifting means relative to said upper portion of said container.
Preferably a lifting harness as above defined further includes a lateral support means adapted to extend about said lifting means part way along their respective vertical lengths.
According to a further aspect of the present invention there is provided a package assembly comprising: of said inner container and further having a plurality of lifting means having free ends adapted in use to be connectable with a suspension means; harness and said inner container in covering over same; outlet means adapted in use to coincide with an outlet provided in the base of said inner container whereby after the removal of said outer container (if it is not provided with or providable with its own outlet) material within said inner container can be discharged therefrom and through said outlet means in said base portion.
According to a still further aspect of the present invention a method of filling a container with a material is provided wherein said container has a cross section including corners, said method comprising the discharge of ma
