Definitions

• the field of the invention is that of the design and manufacture of plastic containers obtained by blow molding or stretch blow molding in a forming mold.
• the invention relates to a container having a shape of substantially rectangular or oval section.
• This type of plastic container generally has at least one wall provided with a so-called “flat” panel, that is to say a panel representing a surface generally used to receive a label.
• flat panel is meant an effectively flat panel, but also a slightly curved or curved panel having one or more radii of curvature such that the panel appears flat (for example one or more radii of curvature or equal to 100 mm).
• a first solution consists in heating the walls of the mold which define the shape of the container formed.
• the heating of the mold walls generally between 10 ° and 65 ° (and more
• heating the mold increases the phenomenon of shrinkage of the plastic at the mold outlet.
• the material conforms properly to the walls of the mold during molding, it shrinks when the container formed leaves the mold. This results in a loss of definition of the details of the container, in particular details of structured patterns comprising curves of small radii, which are the most difficult to obtain.
• the container formed then generally corresponds to the imprint of the mold with the exception of certain details which form in the mold, but which disappear from the container removed from the mold following the shrinkage of the material.
• the fact of heating the mold prevents the plastic material, in particular the PET, from congealing against the walls of the mold. On leaving the mold, the phenomenon of withdrawal then causes the disappearance of precision shapes from the container.
• the second solution is to make reinforcing means on the flat panel.
• These reinforcing means conventionally take the form of grooves made on the flat panel, the grooves being generally parallel to each other and equidistant from each other.
• This second solution makes it possible to keep a manufacturing cost substantially equal to that of conventional manufacturing.
• these grooves in order to be effective, most often have a significant depth, so that they are visible under the labels of the containers.
• these grooves are generally positioned so that the deformation of the panel is only ensured along a single axis of deformation. Therefore, deformation along another axis of deformation is possible.
• the grooves are positioned substantially
• the deformations are marked between the grooves.
• the deformations are marked at the ends of the grooves.
• the invention particularly aims to overcome the drawbacks of the prior art.
• the invention aims to provide a plastic container having a flat panel whose deformation is limited, or at least controlled, so as not to cause a quality defect which would be perceived by a consumer, as well as to allow labeling of the container.
• the invention also aims to provide such a container which is simple to manufacture, and in particular adaptable to a conventional manufacturing process.
• the invention further aims to provide such a container, the flat panel of which has reinforcing means which are invisible, or almost invisible, under the label.
• a plastic container of the type comprising a panel having at least a radius of curvature greater than 100 mm, the panel having reinforcing means, characterized in that the reinforcing means include:
• each internal groove having two ends each opening into the peripheral groove, or into another internal groove.
• the peripheral groove defines a reinforced area of the flat panel. An area thus delimited ensures that the deformation constraints will be concentrated there, which will make it possible to increase the quality perceived by the consumer.
• the internal grooves allow the area surrounded by the peripheral groove to be stiffened so that the entire flat panel is stiffened.
• the fact that the internal grooves open out is either in the groove
• peripheral also allows the flat panel to contribute to preserving the shape of the container (that is to say that the flat panel contributes to preventing the overall deformation of the container).
• the peripheral groove defines a closed reinforcement contour.
• the closed contour offers an additional guarantee of security in terms of resistance to deformation of the flat panel.
• the closed contour makes it possible to delimit a labeling area, that is to say an area reserved for the bonding of the label around the means of
• the peripheral groove defines an open reinforcement contour.
• An open reinforcement contour also gives good rigidity to the flat panel. Short openings of the contour are however favored compared to long openings which increase the risk of deformation of the flat panel.
• the discontinuity of the peripheral groove ensures this voluntary deformation of the container for the extraction of the product that it contains.
• the internal grooves are arranged to form a pattern of braces.
• the cross pattern makes it possible to stiffen the flat panel along several axes.
• the braces increase the perceived quality of the container by the consumer.
• the spider pattern provides an aesthetic appearance to the container.
• the internal grooves are advantageously rectilinear.
• the straightness of the internal grooves contributes to the perceived quality of the container, and in particular to the rigidity of the flat panel.
• the internal grooves are curvilinear.
• Such internal grooves then retain their stiffening power while providing a fantasy, especially in the case where the label is torn off and made appear the reinforcing means, or for containers having particular shapes such as rounded shapes.
• the internal grooves include:
• Such an arrangement of the internal grooves allows the production of the cross pattern.
• such an arrangement of the internal grooves ensures a regular mesh, that is to say surfaces between the internal grooves which are substantially identical.
• the peripheral groove has a depth of between 0.3 mm and 1.5 mm.
• This depth range makes it possible to give the peripheral groove both good stiffening power, without being visible under the label.
• each internal groove has a depth of between 0.3 mm and 1.5 mm.
• the reinforcement means have a PRP / PRI ratio of between 0.8 and 2.4, with:
• This ratio between the depths of the internal grooves and the peripheral groove makes it possible to obtain good homogeneity of stiffening and, in particular, to prevent either the peripheral groove or the internal grooves from being too flexible with respect to each other. to others. Thus, a phenomenon of combined rigidity and flexibility is avoided, which could affect the good quality perceived by the consumer of the container.
