DESCRIPTION:

BRIEF SUMMARY
This invention relates to a package protecting its contents against the influence of light, gases and aromas but making possible a visual control of the contents before it is taken out of the package.
Due to their properties, many products require a package which is light-proof, gas-tight or aroma-tight in order that the properties of the product in the package should not be impaired. Many packages meeting these demands are also known, and e.g. different plastic foil materials have been found to be suitable for manufacture thereof. Many laminated plastic foil materials, especially laminates of plastic foil and aluminum foil, have been found to be an excellent combination of light and gas tightness, as the same time as they have a good mechanical strength, can be easily worked to packages of various shapes and are inexpensive. It is also of importance that such laminates can be produced that have a sufficient heat stability to be autoclaved. In this way the package and the enclosed product can be heat sterilized simultaneously, which is of a great importance when packing e.g. medicines and bandaging materials.
One disadvantage of light-proof packages of plastic foil material is that they do not make possible a visual control of the contents before the package is opened. However, in certain cases it is very desirable to be able to check the contents visually in an unopened package before it is to be used, and in some of these cases this is an imperative demand. This applies especially to solutions intended to be infused intravenously or otherwise administered parenterally to a patient. Here it is absolutely necessary to be able to check visually before the infusion or administration that the solution has not deteriorated and e.g. has not become cloudy, discoloured or deposited a precipitate. An administration of such a deteriorated solution may have fatal consequences for a patient. The same also applies to blood for transfusions.
Glass bottles with rubber stoppers have been used for a long time as packages for infusion solutions and blood for transfusion. The glass bottles can be stored in a light-proof casing an permit a visual control of the contents before use and, moreover, they are gas-tight and protect against microbial contamination if the rubber seal is suitably designed. However, they have also considerable disadvantages as they are heavy and sensitive to shocks. They are also relatively expensive to manufacture. Furthermore, it is necessary to introduce air into the bottle when liquid is to be drawn off, and this may cause contamination of the contents. In order to eliminate the disadvantages of the glass bottles, various types of plastic packages in the form of bags for infusion solutions and blood for transfusions have recently been developed. Such packages can be compressed as the contents are consumed, and no air need be introduced. However, the problem remains that if the package is to protect the contents against light in storage, it has not been possible to check the contents visually before use. It might be possible to use a separate, light-proof casing of e.g. cardboard or opaque plastic foil, but this will be impractical when handling and using the package.
The disadvantages indicated above are eliminated by the package of the present invention and a bag-shaped package is provided which protects the contents of the package against light and gases for the whole time in storage and transport, but makes possible a visual control of the contents before it is taken out of the package.
The invention refers to a package for protection of a product packed therein against the influence of light, gases and/or aromas, and which makes possible a visual control of the product before the package is opened, the package being characterized in that it comprises a light-proof outer bag and a light permeable inner bag placed inside the outer bag, the outer and inner bags each being sealed at one of their ends and bonded to each other around their periphery close to their other end, and, moreover, being con
