Abstract
An improved packing more particularly for foodstuffs of the type composed of a receptacle sealingly closed by a removable lid and comprising therein a perforated separation wall in form of a grid disposed substantially in parallel to the bottom of said receptacle thereby to provide a two-section separation of the latter such that the upper compartment is reserved for lodging the foodstuff to be preserved, with the lower compartment being adapted to receive an absorbent material intended for absorbing the exsudate from said foodstuff, wherein there is provided on, or in, said absorbent material such material capable, under the effect of water from the exsudate, of releasing an inert gas in such quantity as to compensate for the loss of pressure within the receptacle on the one hand, and on the other hand, capable of creating such an atmosphere as to prevent formation of secondary noxious products, and compensating for the loss of some of the constitutive components of the foodstuff carried away with the exsudate.
