Media container and media protection apparatus

Abstract

The invention discloses a media container (4) adapted to protect a medium (10) havingan opening (12) adapted to allow that a medium (10) is put into the media container (4) ; anda closure (8) by which the opening (12) may be closed; wherein the closure (8) is adapted such that in its opened state air from the media container (4) may be exhausted, that in its opened state protective gas may flow into the media container (4) and that in its closed state entering and / or exiting of a fluid from the media container (4) and / or into the media container (4) is prevented.

AI Technical Summary

Benefits of technology

The present invention is a media container that protects film or other media from aging and mold infestation. The container has an opening and a closure that can be opened to exhaust air or vacuum off the container and closed to prevent fluid from entering or exiting the container. The closure has a protective gas opening that allows nitrogen or carbon dioxide to flow into the container to protect it from humidity and slow down the growth of bacteria or mold. The container is designed to prevent spur growth and avoid the vinegar syndrome, which causes damage to sensitive materials. The invention also ensures that the media is protected from firewater and dust while being stored.

Problems solved by technology

Mould poses a significant risk for books, arts on paper and film material.

This may be a matter of hours.

Some mould fungus species, such as aspergillus fumigatus, are poisonous.

Contact with the mould fungi may trigger allergies even with persons which are not allergy prone.

Therefore, also inactive mould fungi still pose a risk for books, film material and art on paper.

Numerous mould fungus species comprise pigments and cause discoloration when resting on material.

A diligent maintenance of the premises and a well operating air filter equipment cannot prevent that warehouses, archives, libraries and museums are not completely free of such organisms.

Once the material is affected by the fungus mesh, it is nearly impossible to recognize an image.

If the relative humidity is for a longer period in direct influence of the material over 70%, it is almost impossible to avoid fungus growth.

Further, film material and paper is damaged under influence of light and therefore it is not advisable to use light against mould.

Once proliferation of mould has commenced, it is extremely difficult to eradicate it, since the possibilities for fighting against it are limited.

Often, the reaction is very tedious.

By the loss of the softener and by separating of the acetate groups the film gets fragile and shrinks.

A further problem is also the different speed of decay of the film basis and the gelatin.

However, the colors may bleach gradually (not comparable with a red cast).

The aging process cannot be stopped but may be slowed down significantly.
