4. List of figures.

  The invention will be better understood, and other features and advantages will appear on reading the description which follows, the description referring to the accompanying drawings in which: Figure 1 shows in exploded form a package of a device with tube cathode (or CRT), in exploded form, according to a particular embodiment of the invention; Figures 2A and 2B illustrate the different parts of the package of Figure 1, in a non-exploded form; Figure 3 shows a method of manufacturing the package of Figure 1; Figures 4 and 6 describe CRT monitor packages according to variants of the invention; and Figures 5 and 6 show a method of manufacturing the packages of Figures 4 and 6 respectively.

  5. Detailed description of the invention.

  The general principle of the invention is therefore based on the implementation of a device package with a CRT type screen (for example a television or computer monitor), the front face (corresponding to the visible face of the screen ) of the apparatus being positioned towards the bottom of the package (at the bottom of the package) and substantially parallel (the angle between the plane of the screen and the bottom plane of the package being less than 10) , or exactly parallel to the bottom of the package which forms a bearing face during transport.

  Thus, according to various embodiments of the invention obtain CRT screen type device packages particularly well suited to their transport, especially between the manufacturing plants and the end user. Indeed, in this way the center of gravity of the device is placed relatively low in the package (the front of the screen of the device is generally much heavier than the rest of the monitor). It is thus possible to stack several packages on one another by reducing the risk of tilting of the assembly. In addition, the package alone is also more stable during handling.

  Moreover, according to several embodiments of the invention, it is possible to reduce the overall volume of the packaging. Indeed, the rear face of the device does not need to be as well protected in a configuration where the screen is directed towards the lower part of the package. In addition, according to variants of the invention, one can take advantage of the box of the device itself which has generally good mechanical strength, for stacking several packages on top of one another, the weight of the packages being supported in partly by the packaging envelopes underneath and partly by the corresponding apparatus cases.

  Thus, the invention makes it possible to increase the number of packages transported, of apparatus with a CRT type screen for a given transport container (for example, by reducing the volume of each package, which reduces the overall volume of a number given packaging and / or by increasing the size of the packaging piles).

  In addition, the orientation of a package being modified according to the three dimensions height, depth and width, optimal loading trucks or containers can often be obtained. Indeed, the dimensions of the containers or trucks used for transport have useful dimensions known and standardized.

  FIG. 1 is an exploded view of a package which comprises: a device with CRT type screen 10 with a rear face 100 and a front face or screen 101; a cardboard envelope 13 comprising an upper face 130 with flaps 133, four lateral faces 132 and a lower face 131; in blocking and protection surround 11 of the apparatus 10, made of cardboard; and blocking and protecting corners 120 to 123 of the polystyrene apparatus 10.

  The blocking and protection corners 120 to 123 make it possible in particular to protect the periphery of the screen 121. The polystyrene is particularly well suited for protection when the packaging is liable to fall several times.

  According to a variant of the invention, the locking and protection wedges 120 to 123 are cardboard or foam expansive, which ensures a good protection for a specific drop of the package.

  In addition, the cardboard is less bulky than polystyrene before its use for packaging (space saving before production).

  The surrounding 11 which surrounds a sideband of the apparatus 10 close to the rear face 100 of the apparatus 10 makes it possible in particular to protect the cabinet of the apparatus 10. The surround 11 preferably has a height h 'of the order of 100 mm.

  The locking and protection wedges 120 to 123 and the surrounding 11 also make it possible to prevent the movements of the apparatus 10 inside the envelope 13. Preferably, they conform to the shape of the corners of the front face respectively. 101 of the apparatus 10 and the rear periphery of the apparatus 10.

  Preferably, the locking and protection wedges 120 to 123 extend along the lateral edges of the apparatus 10 over a height h of between 25 and 50% of the depth p of the apparatus 10. The thickness of the corners blocking and protection 120 to 123 is preferably between 2 and 4 cm.

  Thus, by way of illustration, for a monitor or a television with a CRT type screen of 29 ", h is preferably of the order of 200 mm, for a device depth of the order of 700 mm.

  According to a variant of the invention, the locking and protection surround 11 is made of polystyrene or expansive foam.

  As illustrated in FIGS. 1, 2A and 2B, the front face 101 of the apparatus 10 is placed against the lower face 131 of the envelope 13.

  Thus, the screen 101 is directed towards the bottom of the package, which is intended to be oriented as shown in these figures during its transport.

  FIG. 2A shows that the surround 11 exceeds a thickness e of the rear face 100 of the apparatus 10. Preferably, this thickness e is less than or equal to 2 cm, which gives the package good stacking resistance .

  Even more preferably, this thickness e is less than or equal to 1 cm, which also allows good resistance to stacking of the package while further reducing the volume of the package.

  In order to reduce or eliminate the friction of the device 10 against the envelope 11, the thickness e is preferably greater than 2 mm.

  In general, a small thickness e makes it possible to use the mechanical strength of the apparatus 10 (in particular of its cabinet) to vertical forces (when the screen is placed horizontally downwards according to the invention) , especially when it is desired to stack several packages on top of one another.

  According to an alternative embodiment of the invention, the package does not include the surround 11 and more generally locking means around or near the periphery of the rear face 100 of the apparatus 10. In fact, the stability of the apparatus 10 in the packaging is provided, since the center of inertia of the apparatus 10 is close to its screen 101 (and thus the bottom of the package).

  Preferably, the outer casing 13 is a cardboard box with grooves parallel to an axis xx ', perpendicular to the front face of the apparatus 10, corresponding to a vertical axis in the transport position of the apparatus 10 in the Thus, the package is particularly resistant to vertical forces, for example when several packages are stacked.

  According to a variant of the invention, the outer casing is a plastic package or a heat-constrained polystyrene film.

  Figure 3 illustrates a method of manufacturing the package of Figure 1.

  More specifically, the manufacturing method comprises a first step 30 of positioning the protections 120 to 123 in the lower corners of the envelope 13 (this envelope being closed on its lower face 131).

  Then, during a positioning step 31, the apparatus 10 is placed inside the envelope 13, the screen 101 directed downwards, applying against the protections 120 to 123. This step 31 can be manual (when the device is relatively light) or mechanical.

  Then, during a positioning step 32, the surround 11 is placed around the periphery of the rear face 100 of the apparatus 10.

  Finally, during a closing step 33, the envelope 13 is closed, the flaps 133 being folded against the surrounding 11 and / or the rear face 100 of the apparatus 10 and fixed by gluing, adhesive tape and / or stapling, for example, so that the package does not open spontaneously. The package is thus ready to be transported by any means, the screen 101 being positioned towards the lower face 131 of the package.

  FIG. 4 illustrates an alternative embodiment of the invention, with an implementation of the apparatus 10 inside the envelope 13, upward screen and reversal of the packaging for transport. The similar elements for the packages illustrated respectively with reference to Figures 1 and 4 have the same references and will not be described further.

  Figure 5 illustrates a method of manufacturing the package of Figure 4.

  More specifically, the empty envelope 13 being reversed and closed on its upper part 130 (this part is therefore provisionally positioned at the bottom), the manufacturing method comprises a first step 50 of positioning the surround 11 in the closed part 130 of the envelope 13.

  Then, during a step 51 of positioning the apparatus 10, the apparatus 10 is placed inside the envelope 13, the surround 11 surrounding the periphery of its rear face 100 directed upwards. This step 51 can be manual (when the device is relatively light) or mechanical.

  Then, during a step 52, the protections 120 to 123 are positioned on the angles of the apparatus 10 between the envelope 13 and the apparatus 10.

  Then, during a closing step 53, the envelope 13 is closed, flaps 134 being folded against the protections 120 to 123 and fixed so that the package does not open spontaneously.

  Finally, during a step 54, the package is returned so that the screen 101 is positioned towards the lower face 131 of the package and directed downwards.

  The package is thus ready to be transported by any means.

  FIG. 6 illustrates an alternative embodiment of a package according to the invention, with an installation of an apparatus 60 inside an envelope 63.

  The package illustrated in FIG. 6 in the form of an exploded view comprises: a device 60 with a CRT type screen with a rear face 600 and a front face or screen 601; a cardboard envelope 63 comprising an upper face 630 (which according to the figure appears on the side) four lateral faces 632 (which according to the figure appear respectively on the top (face with flaps 633), the underside and on two sides) and a lower face 631 (which according to the figure appears on the front); four blocking and protective parts 620 to 623 of the polystyrene apparatus 60; and two reinforcing plates 64 and 65 preferably made of cardboard.

  The blocking and protection parts 620 to 623 extend along the lateral edges of the apparatus 60 over its entire depth, preferably following the shapes of the lateral edges of the apparatus 60. They make it possible in particular to protect the cabinet and the cabinet. 60. They also make it possible to prevent the movements of the apparatus 60 inside the envelope 63. The polystyrene is particularly well suited for protection when the packaging is likely to fall several times. . Its thickness is preferably between 2 and 4 cm.

  According to a variant of the invention, the locking and protection wedges 620 to 623 are made of cardboard or expansive foam, which makes it possible to ensure good protection for a specific drop in the package.

  The flaps 633 are positioned on two of the sides 632 of the envelope 63. In order to increase the strength of the sides 632 (in particular vertical mechanical forces when several packages are stacked 20 and / or side impacts (especially during handling), and / or when the grooves on the sides 632 with flaps are horizontal), reinforcing plates 64 and 65 are provided which are placed between the flaps and the pairs of locking pieces 610, 611 and 620, 621, respectively. The dimensions of the plates reinforcement 64 and 65 are the same as those of the inner faces 632 of the envelope 63 against which they apply. Preferably, the reinforcing plates 64 and 65 are made of cardboard with grooves parallel to an axis xx ', perpendicular to the front face 601 of the apparatus 60, corresponding to a vertical axis in the transport position of the envelope 63. Thus, the packaging is particularly resistant to vertical forces, for example, when several packages are stacked.

  According to an alternative embodiment of the invention, there are provided four reinforcing plates each being placed against one of the sides 632. Thus, the four sides are reinforced. These plates are preferably in cardboard with vertical grooves.

  As illustrated in FIG. 6, the front face 601 of the apparatus 60 is placed against the lower face 631 of the envelope 63. Thus, the screen 601 is directed towards the bottom of the package during its transport (the axis xx 'is vertical).

  Furthermore, it is preferentially provided handles placed on two opposite sides and vertical packaging and facilitate its manual transport. Thus, the handles can be on the sides 632 with flaps or without flap. Preferably, the handles are placed on the sides adjacent to the reinforcements. According to the illustrated embodiment, the reinforcing plates 64 and 65 respectively comprise recesses 640 and 650 which after positioning in the casing 63 are located opposite recesses 634 in two opposite flaps 633. The recesses 640, 650 and 634 thus form the handles of the package. Their dimensions are of the order of 40 mm (in the vertical direction) x 100 mm (in the horizontal direction) Preferably, the handles are positioned in a substantially median position (in the vertical direction), in the upper part of the sides 632 ).

  Figure 7 illustrates a method of manufacturing the package of Figure 6.

  More specifically, the manufacturing method comprises a first step 70 of positioning the reinforcing plate 65 at the bottom of the envelope 63 (this envelope being closed on the corresponding lateral face 632, this face being preferably placed on a horizontal flat surface, the flaps being open on the opposite face 632).

  Then, during a step 71, two locking pieces and protections 620 and 621 are positioned in the lateral angles of the envelope 13.

  Then, during a step 72 of positioning the apparatus, the apparatus 60 is placed inside the envelope 63, the screen 601 directed towards the lower face 631, and two lateral edges of the box of the apparatus 60 respectively applying against the protections 620 and 621. The step 72 can be manual (when the apparatus is relatively light) or mechanical.

  Then, during a step 73, two locking pieces and protections 610 and 611 are positioned in the lateral angles of the casing 13 by applying respectively to the two lateral edges of the box of the apparatus 60 remaining at protect.

  Then, during a step 74, the reinforcing plate 64 is positioned horizontally on top of the locking and protective parts 610 and 611.

  Then, during a closing step 75, the envelope 63 is closed, the flaps 633 being folded against the reinforcing plate 64 and fixed by gluing, adhesive tape and / or stapling, for example, so that the packaging does not open spontaneously.

  Finally, during a turning step 76, the closed envelope 63 is rotated to 90, so that the lower face 631 is found downward. The screen 601 of the device 60 is thus directed downwards allowing secure and optimized transport of the package.

  Of course, the invention is not limited to the embodiments described above.

  Those skilled in the art may in particular consider any type of packaging suitable for the transport of cathode ray tube apparatus, the screen being directed downwards in its packaging.

  The devices with a CRT screen themselves may be of any kind: they may be in particular small monitors or televisions (for example 14 ') or very large (more than 90 cm diagonally), of any format ( 4/3 or 9/16 for example) or adapted to various applications (in particular television screen, computer monitor).

  In addition, the materials used for the envelope and the means of protection and / or blocking may be any remaining adapted to the transport of apparatus with a cathotic tube screen for reasons including economic, mechanical strength, impact resistance , weight, volume and / or ease of implementation.

  In addition, those skilled in the art will adapt the methods of manufacturing apparatus packaging with CRT screen and, more generally, the various elements forming a package and their relative positions.
