Abstract:
A method of sterilizing a paperboard material having a surface characterized by one or more aberrations in the smoothness and/or continuity thereof comprising the steps of:a) providing a reservoir of sterilant fluid,b) providing a roll having at least a portion of its outer circumference at least partly submerged in said fluid, said roll having defined in the outer circumference thereof a plurality of minute discrete pores opening outward of the outer circumference of the roll, said pores being spaced apart by respective minimal distances,c) rotating said roll within said fluid such that said pores of said roll receive therein a quantity of said fluid,d) removing from the outer circumference of said roll substantially all sterilant fluid not disposed within said pores,e) thereafter, passing said paperboard material over the exposed portion of said roll with the aberrated surface of the paperboard material in rolling engagement with the outer circumference of said roll and contiguous with said pores whereby the fluid contained within said pores which are engaged by said aberrated surface is wettingly transferred to said aberrated surface of said paperboard material.
