Description

embossing liefs, screening or the like.

  The present invention relates to a package comprising a blank provided with a plurality of panels, said blank being able, after folding, to form a case for a content to be packaged, such as a longiform sample, as well as the method of

reiisation of the packaging.

  We already know packaging of this type made from a cardboard blank with 2 or 3 panels and presenting

  a perforation intended for anchoring the sample.

  There are also packaging of this type in thermoform polymer. However, the existing packagings present a certain

number of disadvantages.

  It is thus sometimes necessary for the sample to present a bonding paste to ensure that it remains in the packaging. Some diluted packaging may also be torn to allow the sample to be removed and therefore does not sell

reusable.

  Finally, depending on the holding means used to hold the sample, the mechanization of the placement of the

  samples can be complex or impractical.

  The present invention aims to overcome these drawbacks.

  More particularly, the invention aims to provide a packaging and its manufacturing process, the packaging can be reused as many times as desired, allowing easier introduction of its content, this introduction can be mechanized. To this end the invention relates to a packaging intended to form a sheath case for a longiform content to be packaged, comprising a blank provided with a plurality of o panels, capable of forming a case, the case being formed by two panels adjacent arranged face to face and connected along their longitudinal edges, the connection between these panels being made on their common longitudinal edge by a fold line and on their longitudinal edges opposite to said edge

common by solidarity.

  A first advantage of the invention resides in the fact that the content is maintained in the case by the simple pressure of the panels of the case on the content. No need to paste anymore

  o hooking or perforations to maintain the content.

  In another embodiment, the adjacent panels

  with the panels forming the ideal case for the ground face to face.

  s These signs can thus serve as an advertising medium.

  In another embodiment, the packaging comprises a second blank provided with at least one panel, said second blank being arranged to be secured to at least one panel so of the first blank capable of forming the case to form a support for the case.

  This medium can also serve as an advertising medium.

  In a variant7 the second blank comprises two panels connected by a fold line, the ends of the two panels being secured on at least part of their

  s surface has at least one panel of the first blank.

  Also in another embodiment, the first and

  second wind blanks produced in different materials.

  o In another embodiment, the first blank capable of forming the case is made of a transparent polymeric material. An advantage is then the visibility of the content maintained in

The case i.

  In another embodiment, the blank capable of forming the case is produced in a material chosen from the following materials: polyethylene terephthalate, polypropylene, chloride

polyvinyl, polyesters.

  In another embodiment, at least one of the panels forming the case, presents on a transverse edge a

cut in the shape of a lunula.

  This characteristic facilitates the introduction of the

contained in the case.

  In a variant, the two panels forming the case o have on their transverse edge a cut in the shape of a lunula, so that the lunules of the two panels solent

  face to face when the case is formed.

  The presence of two lunules facilitates both the introduction and

['extraction of the contents of the case.

  According to another aspect of the invention, the subject of the invention is a method for producing the packaging described above. In one embodiment in which the packaging comprises a second blank, the method comprises the steps consisting in: o - securing at least one panel of the second blank on part of its surface to at least one of the panels adjacent to the panels forming the 'case of the first blank; - joining face to face the panels adjacent to the panels forming the case of the first blank;

  these two stages being carried out in any order.

  In another embodiment, the method comprises the steps consisting in: - securing a panel of the second blank on part of its surface to one of the panels adjacent to the panels forming the case of the first blank; - floor idarize face against face the panels adjacent to the panels forming the case of the first blank; - secure the other panel of the second blank to the other

adjacent panel of the first blank.

  A particular embodiment of the invention will now be described by way of nonlimiting example, with reference to the accompanying diagrammatic drawings in which: FIG. 1 is a perspective view of a first embodiment of the packaging according to [' invention; Figure 2 is a plan view of a first blank of the package according to the invention; - Figure 3 is a plan view of a second blank of the packaging according to the invention; Figure 4 is a perspective view of a second embodiment of the packaging; o - Figure 5 is an enlarged partial cross-sectional view of the packaging shown in Figure 1; The packaging represented in FIG. 1 is composed of a first blank 1 and of a second blank 2 represented respectively in FIGS.

2 and 3.

  The blank 1 is substantially rectangular and of dimensions L1 in a first direction D1 and 11 in a second

  direction D2 substantially perpendicular to D1.

  In the remainder of the text, the transverse term will refer to the direction D2, while the longitudinal term will refer to

direction D1.

  The first blank 1 has four adjacent panels two by two in the longitudinal direction: two substantially identical end panels 3a and 3b and two

  sensibly identi ed central panels 4a and 4b.

  o The central panels 4a, 4b are intended to form a case

  packaging for a longiform sample 8.

2841225;

  The central panels 4a, 4b are separated by a line of

longitudinal folding or creasing 5.

  The end panels 3a, 3b are separated from the central panels 4a, 4b by fold or crease lines

  longitudinal 6a, 6b respectively.

  The blank 1 is symmetrical with respect to a perpendicular plane

  on the blank and passing through the fold line 5.

  The central panels 4a, 4b each have a lunula 7a, 7b arranged on their transverse edge, on the same side of the

blank 1.

  In the embodiment represented in FIG. 1, only one of the

  central panels 4a, 4b have a lunula.

  The first blank 1 is made of transparent plastic. This material is rigid enough for the case to hold the sample by simply pressing its panels on the sample. This rigidity can be provided by a

  sufficient thickness or by the nature of the material.

  The blank 1 can be of material chosen from the following materials: polyethylene terephthalate, polypropylene, chloride

polyvinyl, polyesters.

  o In the case of polyesters or polyvinyl chloride, the fold lines 5, 6a, 6b can be produced by applying a high frequency and a pressure to the material. This process has the advantage of obtaining a fold line without

bleaching in use.

  This method of forming folds also makes it possible to facilitate the opening of the shaped case. The second blank 2 of the package is substantially rectangular and comprises two substantially identical panels 1 Oa, 1 Ob linked by a fold line 11

o longitudinal.

  The longitudinal ends 12a, 12b of the panels 10a, 10b are intended to be secured on at least part of their surface to form a support for the packaging case

(Figures 1 and 5).

  This medium can in particular be used for advertising purposes. o This blank 2 can be made of cardboard, cardboard coated with polymer, molded cellulose, polymer or equivalent materials. In the embodiment represented in FIG. 4, the first blank is used alone. The end panels 3a, 3b can then have a greater width in order to facilitate the

  grip the case and serve as an advertising medium.

  The packaging process is now

described.

  In a first embodiment, the method comprises the following stages: - the end panels 3a, 3b of the first blank 1 wind joined face to face; - the ends 1 2a, 1 2b of the panels 1 Oa, 1 Ob of the second wind blank joined together on a part of their surface to the end panels 3a, 3b on either side

of these (Figures 1 and 5).

  In a second embodiment, the method comprises the following stages: o - one of the end panels 3a, 3b of the first blank 1 is secured on part of its surface at one of the ends 12a or 12b of the second blank 2; - the end panels 3a and 3b are joined face to face; - the second end panel 3b, 3a of the first blank is secured on part of its surface at the other end

12b, 12a of the second blank 2.

  These two last steps can possibly be

carried out simultaneously.

  The panels 3a, 3b, adjacent to the panels 4a, 4b forming the case wind preferably joined together on a part of their surface located near the fold lines 6a, 6b with the panels forming the case, along the entire length L1 of these

  fold lines, this in order to ensure the rigidity of the latter.

  The different wind panels joined together by gluing, by

  welding, stapling, or any other equivalent means.

  The method of making the packaging shown in Figure 4 requires only one step of securing the panels

  end 3a, 3b over part of their surface.

  In the case where the first blank 1 comprises more than four panels, the process for producing the packaging comprises the step consisting in securing the longitudinal ends of the panels of the first blank forming the case by securing the

  panels adjacent to said panels forming the case.

  The method can then comprise a step consisting in securing at least one panel of the first blank to at least

  a panel of a second blank serving as support.

  Once the end panels 3a, 3b are joined face to face, the central panels 4a, 4b form a case by

  fold along the fold line 5.

  Figure 5 shows an enlargement of the areas of

  bonding between the different panels.

  Three bonding zones can be defined: - a bonding zone A between the faces of the panels 3a and 3b; - A bonding zone B between the faces of the panels 3a and 1 0 a; - A bonding area C between the faces of the panels 3b and 10b. In other embodiments not shown, the panels 1 Oa, 1 Ob can be inserted between the panels 3a, 3b, a bonding zone being present between each padre

  o panels arranged face to face.

  We can also consider that the panels of the first and

second blanks are intercalated.

  In the case formed by the panels 4a, 4b of the first blank 1, can be inserted a longiform sample 8 (Figures 1 and 4) held by the simple pressure on its surface of the panels 4a, 4b. This case can be reused as many times as necessary to

contain the longiform sample.
