FIELD: packaging industry.SUBSTANCE: invention relates to the container, such as can, for filling with a product to be conserved, in particular foodstuff, and the named container contains a can housing (1) consisting of a bottom (2) element which passes into a sidewall (3), and the named housing (1) can limits the internal conservation volume (6) and contains the internal surface (7) made partially of tin covered with the protective layer (10) intended for reduction of chemical activity of the named product to be conserved. According to this invention the protective layer (10) contains a set of pores (11) distributed at least on a part of its surface through each of which the access to the zone (7a), opposite to the named internal surface (7) can be provided, from the named internal volume (6) of the container, in particular to provide dissolution of tin in a product and at the same time to minimise the negative impact, caused by chemical activity of the named product to be conserved, at the appearance of the named tinned internal surface (7).EFFECT: design improvement.27 cl, 2 dwg |
