Definitions

  • the invention relates to the technical field of envelopes.
  • envelopes is meant here flat cases, for example of shape rectangular, intended for correspondence and, more generally, for transport and in particular postal distribution.
  • the envelopes are provided of cellular material comprising air bubbles.
  • This material is known in oneself for a very long time (see for example American patent US-2,294,389, from 1965).
  • This first series of bubble envelope production can be illustrated by the following documents: EP 0.172.142, US-5.273.361, FR-2.163.311, DE-200.06.056U.
  • the envelopes are provided foam padding. Examples of making such envelopes can be found in the following documents: FR-2.172.830, US-4.087.002.
  • the first series of embodiments has several drawbacks.
  • the volume / weight ratio is very high, which makes expensive transport and storage of envelopes before use.
  • the second series of productions also presents many disadvantages.
  • the volume / weight ratio remains high, which, again, makes it expensive to transport and store envelopes before use.
  • the document FR-2.139.749 describes a composite material comprising expandable particles containing a polar compound such as anhydride citraconic, ethyl acrylate, beta hydroxyethyl acrylate.
  • US patents US-4,620,633 and US-4,193,499 describe envelopes currently sold under the XPANDER PAK brand.
  • the US Patent US-4,620,633 describes double-walled envelopes between which an expandable material is placed. In the initial state, this material expandable is compressed because housed in an internal pocket in the envelope, this pocket being vacuum. The user must perforate the envelope, after placing the product to be protected in the envelope, so that the expandable product swells by air inlet.
  • the envelopes described in the documents US-4,193,499 and US-4,620,633 are of delicate use. There is a risk that perforation of the envelope causes injury to the user or deterioration of the object contained in the envelope, object that one wishes protect precisely against such accidents.
  • microwaves as described in the document US-4,193,499 requires a specific apparatus suitably adjusted.
  • the use of microwaves is not very compatible with sending, in the envelope, of metallic materials.
  • the invention aims to provide an economical solution to several of the problems with previously known products.
  • the invention aims to provide a new method of manufacture of envelopes for fragile objects, the envelopes obtained being more easily recyclable than those known, the envelopes obtained being more reusable and less transportation and storage before use expensive, the volume / weight ratio of these envelopes, before use, being significantly reduced.
  • the cushioning material is a natural foam or synthetic.
  • the invention relates, according to a second aspect, to packaging envelopes obtained by implementing the method presented above, said cases being each arranged in an enclosure, the enclosures being grouped in an over-enclosure, over-wrapped, from which air has been expelled by compression or suction before closing.
  • the enclosures containing the envelope (s) are made of translucent, transparent, semi-transparent polymer material, or provided with a content viewing window.
  • any paper envelope or conventional kraft can be used as a case.
  • the cushioning material being placed in said case, without advantageously be attached to it, it is easy to reuse this material, the case being able to be recycled or reused elsewhere.
  • a strip of cushioning material or more bands can be placed in the case, this band (these bands) being possibly provided with reliefs, as is known per se.
  • the flexible enclosure in which the cases are placed under vacuum is transparent, translucent or semi-transparent, or else provided with a transparent, translucent or semi-transparent window. The user can thus visually identify the nature, even the number of envelope cases contained in the flexible packaging enclosure under empty.
  • the flexible enclosure is advantageously provided with precut means.
  • Such pre-cutting means are known in themselves and can be for example the following.
  • the enclosure comprises a two-layer film, one of the layers being provided with a plastic material pre-cut according to a line, for example by laser cutting.
  • a tear strip is stuck on the enclosure, one end of this strip being exposed so as to allow manual traction on this strip.
  • Such tapes are used currently, but for much more modest efforts, in packaging packs of cigarettes or audio cassettes.
  • a side cut or pre-cut forms a tear primer, the film constituting the enclosure, mono or multilayer, having an orientation preferential providing the linear propagation of this tearing (by example PE oriented).
  • the enclosure is closed by welding (high frequency, ultrasound or heat sealing, depending on the material used in particular) and the welding area is provided with two opposite grip.
  • the process can be implemented for storage and transport padded or bubble envelopes, individually placed in an enclosure flexible, these envelopes being compressed mechanically and / or by suction air contained in the enclosure before closing of this enclosure, for example by welding.
  • the envelopes are placed in number in a flexible enclosure in which air is expelled by suction or mechanical compression, each of these envelopes being itself placed in a closed enclosure in which air has previously been expelled by compression or aspiration.
  • the user When the user opens the first overpack enclosure, it access the enclosures containing the envelopes and can take them one by one one, as required, the unused envelopes remaining in the state compressed storage or transport.
