  • Patent number: 9915484
    Abstract: Process for producing an element comprising a multilayer architecture, the layers of which comprise primary channels on their upper faces, said process comprising the following successive steps: (a) producing secondary channels on the lower faces of each layer, each secondary channel being intended to be facing a primary channel of the neighboring lower layer within the architecture, (b) depositing a coating that protects against oxidation at a temperature of between 500° C. and 1000° C. and against corrosion over all of the lower and upper surfaces of the layers, (c) sanding or mechanical cleaning of the surfaces intended to be assembled, and (d) assembling via superposition of the various layers so that each secondary channel of a lower face of an upper layer is facing and is centered on a primary channel of the neighboring lower layer, the width of each secondary channel being greater than the width of the primary channel which it is facing within the architecture.

  • Patent number: 9352881
    Abstract: The invention relates to an essentially tubular flexible packaging intended for containing a semi-liquid or pasty product, which includes an apron, a head, an added piece of material at least on the inside of the apron, and optionally a lid, the apron consists of a rolled-up sheet and includes a longitudinal weld for assembling the edges thereof together, and the head being attached to the edge of one of the ends of the apron. The apron includes a ratio of at least 30% of recycled material or material from renewable resources, and the added piece of material is arranged so as to eliminate a discontinuity in the inner surface in the area of the longitudinal weld.

  • Publication number: 20050031232
    Abstract: A package forming a container with two side walls, a base and a top opening, the container being made from a hand tearable material, and having an incipient tear tab for first opening of the package once it is filled and sealed. Each side wall has at least a first stiffening element locally reinforcing the material, the stiffening element being selected such that the propagation energy of the incipient tear tab is lower than the rupture energy of the stiffening element. Each side wall includes means for guiding the incipient tear tab on first opening, with the incipient tear tab located between the first stiffening element and the guide means, so that the tear tab is guided.
