Procedures and devices to transform three dimensional flexible sealed containers of at least two faces or sides and which in their interior contain at least one fluid and, optionally or complementarily, solid or solids, granulates or powders, by folding at least once over itself, towards at least one direction: at least part of at least one flap/triangular shape (36) or strip (37) over at least part of another part of the same flap/triangular shape (36) or strip (37), alongside with also previously and/or posteriously there will be a seal of at least one part by at least one face or side of the flap/triangular body (36) or strip (37) generated and/or being this one folded at least once over itself.

This system supposes improvements regarding the inalterability of the container, economic and ecological considerations by not having to cut the flaps or triangular shapes, keeping it intact, without fissures or tearings in the initial container body, transformed in 3D.

At the same time, the following advantages are important:

by guaranteeing the conservation and useful life of the container without porousness or leaks, from the moment of the 3D transformation until its later opening and consumption of the product contained within.

by not requiring any sort of adhesive or contact glue to attach or fold the flap/triangular shape (36) or strip (37).

by impeding that the Production Facility generates any defective container transformed in 3D.

by having the invention containers be more stable because the support face or side is wider and more consistent, having at least part of the flap/triangular shape (36) or strip (37) as a support surface in the base.

A paper inner container for storage of a refilling liquid content, the paper inner container including a body (11), which includes a body front panel (7), a body right side panel (6), a body left side panel (8), and a body back panel (5).
