The present comprises wire containers formed by a cardboard cylinder with the convolute process, with Kraft paper and sodium silicate as adhesive. The layers can vary from 8 to 10. At the ends there are reinforcements of galvanized sheet. Generally, with no cap or closure loop, but they can be used in transport. In the interior it is placed a core, a cardboard cylinder, of less diameter made of 5 layers of semi-Kraft paper, convolute-formed and glued with corn dextrin at the bottom center. The core height should not surpass the container body. Both, body and core could have spyholes which are circular or rectangular perforations which allow seeing the container content. In case of being fitting-together, the bottom is formed by two cardboard discs, one of them fitted-together with the reinforcement sheet and the cardboard body. The bottom is reinforced by means of a process in which a polyethylene layer is applied.
