Definitions

  • the invention refers to an envelope / bag for postal use that contributes, to the function to which it is intended, advantages and characteristics, which will be described in detail below, which assume a remarkable novelty in the current state of the art.
  • the object of the invention focuses on an envelope / bag for postal and courier services, whose structural configuration allows, at will, to create air chambers that convert it into a padded envelope to serve as a protective packaging of the contents , allowing the use of it both with and without such cameras, such as any over current and, in any case, providing the advantage of flat storage taking up minimal space.
  • the configuration of the device of the invention not only allows offering a protective means for its content, but also thermally isolates it in those cases that may be necessary.
  • the method of obtaining the envelope / bag is also an object of the invention, in order that said procedure allows the use of sheets of thermoplastic material of less thickness than those used to date, with the consequent economic savings that this entails.
  • the field of application of the present invention is part of the industry sector dedicated to the manufacture of packaging, packaging and similar elements, focusing particularly on the field of envelopes and more particularly, padded envelopes for postal use.
  • quilting are known, which are formed by at least two layers of material between which there are a plurality of air chambers that provide protection for the content.
  • intermediate protective packages such as JP 2008254780, which describes an intermediate package consisting of a kind of inflatable cover in which a plurality of independent chambers participate. They swell through a conduit common to all of them from which a plurality of inflation valves emerge in a branched manner.
  • this type of device has a structure that is substantially different from the structural characteristics required by a postal delivery support, such as the fact of having a closing flap. self-adhesive, so that, as stated above, they define an "intermediate" packaging, which must be complemented with an envelope in which to be introduced, in order to be finally issued, which complicates and makes the process of using everything set.
  • the process used to obtain the inflatable chambers in this type of intermediate packaging is based on the technique of thermo-welding, a process that requires that the walls of thermo-plastic material used be of a certain thickness to ensure the tightness, that is to say a correct and continuous fusion between these layers, or forces the use of other materials, which negatively affects the cost of the final product.
  • the aim of the present invention is to develop a new type of envelope that allows it to be converted only when it is of interest in a padded envelope with air chambers and, when not in use, remains a plain envelope.
  • the envelope / bag for postal use that the invention proposes is configured as a novelty within its field of application, since, according to its implementation and in a restrictive way, the aforementioned objectives are satisfactorily achieved, the characterizing details being that make it possible and that distinguish it from what is already known conveniently included in the final claims that accompany the present description.

  • the envelope is configured from at least two layers of thermoplastic sheet adhered to each other with an adhesive that forms the chambers when applied only at certain points, there being, at least, a valve that communicates with said chambers for provide inflation thereof, by any appropriate system, for example by blowing with the mouth or by another mechanical inflation element.
  • a valve that communicates with said chambers for provide inflation thereof, by any appropriate system, for example by blowing with the mouth or by another mechanical inflation element.
  • this valve is incorporated in the envelope in a discreet and hidden place to avoid deterioration, preferably in the flap area, next to the envelope closure adhesive, so that, preferably, said flap serves to hide the valve once inflated the cameras.
  • the envelope has an additional layer, of the same or other sheet material, which is arranged externally and incorporated in its interior, as an inner sleeve, the two layers of sheet adhered forming the chambers, being independent to said additional outer layer.
  • the envelope is configured with the external welds necessary for its completion, presenting variable measures depending on the needs of each case, materials of different polymers and thicknesses, printing and exterior codes, as well as pockets for delivery note etc.
  • the layers that determine the inner jacket of the envelope are provided that they may have different composition and thicknesses of different materials to achieve different elasticity / stiffness properties in the internal and external area of the assembly.
  • it may incorporate one or more intermediate layers of insulating material between the jacket that determines the inflatable chambers and the outer layer of the envelope.
  • the configuration of the inflation valve that participates in the envelope is obtained by two sheets of thermoplastic material of adequate length and width depending on the dimensions of the envelope in which it is applied, which adopts a tubular configuration, that is, open at its ends, and which is fixed by its lateral edges to the body of the envelope and between the two walls that define its inflatable chamber, tubular body in whose interior a series of transverse partitions participate that do not extend to the entire width of said tubular body, and which are arranged alternately on one and another side edge successively, which determines a unique conduction that adopts a zig-zag configuration, which hinders the loss of air through it.
  • the outer shape of the envelope can be printed with its mandatory flap with different types of adhesive or security.
  • the sheets used can be transparent colored or opaque to the content.
  • the size of the device will respond to the standard for postal or courier use, although envelopes of sizes could be manufactured according to the needs of each client.
  • thermoplastic polyolefin based materials As for the materials used, these are thermoplastic polyolefin based materials, fully recyclable, reusable and safe.
  • the envelope can be obtained from sheets of thinner plastic material, which makes it possible to reduce manufacturing costs. From this structuring, it is folded by means of a transverse fold line of the assembly, to fix the lateral edges again, that when presenting in this configuration a greater number of layers, they can be fixed interchangeably by means of adhesive or by thermo- welding, based on a greater participation of plastic material in these areas, thus obtaining the most basic version of the envelope, which would remain open.
  • the layer that determines the external surface of the device is more rigid and thick, while the two layers that define the internal air chambers can be as thin and flexible as possible, although they can be of different thicknesses and / or materials, thus minimizing the manufacturing costs of the device.
  • the sheet that defines the outer face of the envelope / bag can be opaque, colored or transparent and can be printed.

Abstract

L'invention concerne aussi bien l'enveloppe que le procédé d'obtention de celle-ci, grâce auquel peuvent être utilisées des feuilles en plastique de moindre épaisseur que celles utilisées dans des supports intermédiaires utilisés à ces mêmes fins. L'enveloppe de l'invention présente la particularité de comprendre une chambre gonflable par l'intermédiaire d'un embout (3), chambre gonflable qui est intégrée dans l'enveloppe même, c'est-à-dire qu'il n'est pas nécessaire de mettre en oeuvre un quelconque type de manipulation ou de montage complexe, de sorte qu'en situation de non utilisation, ladite enveloppe présente une occupation volumétrique minimale, et une fois gonflée elle permet de protéger et/ou d'isoler son contenu de manière simple et économique.
