Method and Machines for Transforming Initial Sealed Packagings into Irregular Cubic or Polyhedral Packagings by Means of Sealing and Cutting Flaps

Abstract

The aim of the invention is to transform an initial packaging consisting of a flexible material such as roll film and sealed by at least two welded joints with a liquid substance inside, into a packaging having a cubic shape with at least three faces. The method and installation using a machine comprise the following steps:

• • 1—the initial packaging is blocked and immobilised by means of subjection clamps which maintain a constant pressure at all times, towards the inside of the initial packaging, but with regulatable damping;
  • 2—an impact clamp (6) hits any of the perimeter lateral side or sides of the initial packaging head-on, so that the packaging inflates, thereby taking on the cubic shape, and the flaps are created; and
  • 3—the flaps are then sealed and cut. The most significant advantages of the invention are that very small cubic packagings can be produced, and at the same time the logistical costs are reduced as a result of the absence of flaps.

Description

TECHNICAL FIELD OF THE INVENTION[0001]It belongs to the packaging inpowderry or sector of Packaging.[0002]The machines and procedures of the new invention together with those already on the market, will jointly participate in a solution, and this is essential for the new process of transforming from an initial bag or sealed container with liquid or air only / inside gas in a container or entirely cubic volumetric three or more faces without flaps all smooth or with one or two cut or unsealed flaps.[0003]The filling machine vertical / horizontal fluid is that previously manufactured the initial container which we break is none other than a two-sided container (can have some face more internal or external secondary packaging as the Stabilo ® pack type) with two or more sealing welds liquid or / and air / gas and little or no volume.[0004]The materials used to fabricate these initial packaging film are of malleable and flexible coil, they may be the following: Just like as plastic or cardboard...

AI Technical Summary

Benefits of technology

[0048]I have developed also a system or process for packaging once they have been processed in the form of cubic figure, it gives them greater stability, rigidity and consistency, through what I have called pinch clamps.

Problems solved by technology

There are other systems that are not entirely volumetric and are always very rectangular containers and unstable: doy pack, stabilo pack, pillow pack (sachet) delta pack.

In these systems just mentioned, also, use only plastic film in reel type, but are not cubic containers less stable (especially at the base) and volumetric anything besides their faces are not smooth and that the pressure exercised substances packed in these containers when pressed, is considerably less.

. . ) but have three drawbacks: increased cost of the final product because the production per unit is slower, the maintenance cost is higher and the raw materials used to manufacture them is more expensive.
