And a bottom material 60 that is superposed on the non-side).

  First, an example of the metal plate 10 as a vapor deposition mask to be packed by the packing member 30 will be described with reference to FIGS. Here, FIG. 12 is a top view showing an example of a metal plate, and FIG. 13 is a diagram for explaining a method of using the metal plate as a vapor deposition mask.

  As shown in FIG. 12 to FIG. 15, the metal plate 10 as the vapor deposition mask in the present embodiment has a substantially rectangular shape in a plan view (in a field of view from a direction orthogonal to the plate surface of the metal plate 10), and more accurately. Has a substantially rectangular outline in plan view. The metal plate 10 has a pair of gripping portions 11 located at both ends in the longitudinal direction in a plan view, and a central portion 13 located between the pair of gripping portions 11. As will be described later, the gripping part 11 is gripped by the gripping mechanism 35 of the packing member 30. The central portion 13 includes a plurality of perforated regions 14 in which slit-like holes 15 (see FIG. 14) are formed. Further, as shown in FIG. 12, a notch 16 is formed in the grip portion 11.

Yes. The vapor deposition material 28 in the crucible 24 is vaporized or sublimated by heating from the heater 26 and adheres to the surface of the glass substrate 22. As described above, a large number of holes 15 are formed in the metal plate 10, and the vapor deposition material 28 adheres to the glass substrate 22 through the holes 15. As a result, the vapor deposition material 28 is formed on the surface of the glass substrate 22 in a desired pattern corresponding to the positions of the holes 15 in the metal plate 10.

  As shown in FIG. 12, a plurality of perforated regions 14 are regularly arranged in the central portion 13. Specifically, the plurality of perforated regions 14 are arranged at a predetermined interval along the longitudinal direction of the metal plate 10 (the direction connecting the pair of gripping portions 11), and are orthogonal to the longitudinal direction. Are arranged at predetermined intervals along the line. Each of the perforated regions 14 has a substantially rectangular shape in plan view, more precisely, a substantially rectangular shape in plan view. In the present embodiment, one perforated region 14 corresponds to one organic EL display device. That is, according to the metal plate 10 (deposition mask) shown in FIG. 12, multi-surface deposition is possible.

  As shown in FIGS. 12 and 14, the numerous holes 15 provided in each perforated region 14 are formed as slit-like through holes having the same shape. Each hole 15 is elongated from one end to the other end in the perforated region 14 along the longitudinal direction of the metal plate 10 (the direction connecting the pair of gripping portions 11). A large number of holes 15 are arranged side by side at equal intervals in a direction orthogonal to the longitudinal direction of the holes. As shown in FIG. 15, the cross-sectional area of each hole 15 in the cross section along the plate surface of the metal plate 10 gradually decreases from one surface 10a of the flat metal plate 10 to the other surface 10b. To go. Here, FIG. 14 is a partial plan view showing the metal plate 10 from the one surface 10a side, and FIG. 15 is a cross-sectional view taken along line XV-XV in FIG.

  As described above, in the present embodiment, the holes 15 are arranged at equal intervals in each perforated region 14. As an example, when the metal plate 10 is used for manufacturing a display such as a mobile phone or a digital camera (for example, about 2 to 3 inches), the arrangement pitch P of the holes 15 (see FIG. 14) is 84 μm (300 ppi) or more. It can be about 254 μm (100 ppi) or less. Further, when the metal plate 10 is used for manufacturing a mobile phone display, the width (slit width) W along the arrangement direction (one direction described above) of the holes 15 should be about 28 μm or more and 84 μm or less. Can do. On the other hand, the spacing between adjacent perforated regions 14 can be about 5 mm to 10 mm.

  The metal plate 10 having the above configuration can be formed as follows. First, the laminated body 18 in which the metal sheet 18a and the resin sheet 18b are joined is prepared (see FIG. 15). Next, etching using a photolithographic technique is performed on the laminated body 18, and the holes 15 reaching the resin sheet 18b are formed on the metal sheet 18a from the side of the metal sheet 18a that does not face the resin sheet 18b. It is formed. In parallel with the formation of the holes 15, the above-described notches 16 are formed in the grip portion 11. Thereafter, the resin sheet 18b is removed from the laminate 18 to obtain the metal plate 10 made of the metal sheet 18a. In the metal plate 10 produced by such a method, as shown in FIGS. 14 and 15, the cross-sectional area of each hole 15 in the cross section along the sheet surface of the metal plate 10 faces the resin sheet 18b. It gradually becomes smaller from the surface (one surface 10a) that was not facing toward the surface (the other surface 10b) that was facing the resin sheet 18b. According to such a metal plate 10, it is possible to perform deposition with a high-definition pattern with high accuracy.

  Next, the packing member 30 for packing the metal plate 10 as described above will be described. As described above, the packaging member 30 includes the support base 40, the pair of gripping mechanisms 35 and 35 fixed to the support base 40, the lid member 50 superimposed on the support base 40, and the support base. 40 and a bottom material 60 superposed on 40. Further, as shown in FIG. 1, the packing member 30 further includes binding means 33 for binding the lid member 50 and the bottom member 60 to the support base material 40. Hereinafter, each component of the packaging member 30 will be described mainly with reference to FIGS. 1 to 6. 4 is a perspective view showing the support base 40 and the gripping mechanism 35, FIG. 5 is a perspective view showing the lid member 50, and FIG. 6 is a perspective view showing the bottom member 60. As shown in FIG. In addition, the support base material 40 shown by FIG. 4 is shown by making the side which faces the cover material 50 into upper direction in drawing. The lid 50 shown in FIG. 5 is shown with the side facing the support base 40 as the upper side in the drawing. The bottom 60 shown in FIG. 6 is shown with the side facing the support base 40 as the upper side in the drawing.

  First, the support substrate 40 will be described. As shown in FIG. 4, in this Embodiment, the support base material 40 consists of flat form. The support base material 40 corresponds to the outer contour of the metal plate 10 that is a package target, and has a substantially rectangular outer contour in plan view. And each holding mechanism 35 is being fixed to the both ends of the longitudinal direction of the support base material 40, respectively. The support base material 40 can be deformed so that the distance between the pair of gripping mechanisms 35 changes. More specifically, as shown in FIG. 7, the support base material 40 includes a pair of metal plates 10 before the separation distance (linear separation distance) Lb between the pair of gripping mechanisms 35 is gripped by the gripping mechanism 35. The metal plate before the gripping mechanism 35 holds the mounting state between the gripping portions 11 and the length Lc or less along the metal plate 10, and the spacing distance (linear spacing distance) La between the pair of gripping mechanisms 35. It can deform | transform so that both the holding | maintenance states which become longer than the length Lc along the metal plate 10 between a pair of 10 holding parts 11 can be taken. In the present embodiment, the support substrate 40 made of a flat plate extends into a flat surface (a flat surface that does not include a curved surface), that is, a state in which the distance between the pair of gripping mechanisms 35 is maximized. Is in a holding state. Further, the separation interval La between the pair of gripping mechanisms 35 in the holding state is equal to or less than the maximum length between the pair of gripping portions 11 of the metal plate 10 deformed by elastic deformation.

  In particular, in the present embodiment, as shown in FIG. 4, a notch 42 is formed on the side of the support base 40 that is not provided with the gripping mechanism 35 (the side that does not face the metal plate 10). The cutout 42 has a substantially V-shaped cross section and extends along a direction orthogonal to the longitudinal direction of the support base 40 (the direction connecting the pair of gripping mechanisms 35). Although the support mechanism 40 itself is slightly elastically deformed, the support mechanism 40 can be bent and deformed from the holding state to the mounting state with the notch 42 as a center (base point).

  Further, as well shown in FIGS. 2 to 3, the support base 40 is formed with a through hole 44 having a substantially rectangular opening shape. The through hole 44 is formed in a region on the support base material 40 that faces the central portion 13 of the metal plate 10 when the metal plate 10 is gripped by the gripping mechanism 35 attached to the support base material 40. Has been. Further, as well shown in FIG. 4, binding means 33 for fixing the support base material 40 to the lid member 50 and the bottom material 60 is arranged on the side surface of the support base material 40. A groove 48 is formed.

  Next, the gripping mechanism 35 will be described. As the gripping mechanism 35, various conventionally known gripping mechanisms that can grip a sheet-like object can be used.

  In the present embodiment, as shown in FIGS. 2 and 4, the gripping mechanism 35 includes a first member 36 fixed on the support base material 40, and a second member 37 connected to the first member 36. ,have. The second member 37 is located between a position separated from the first member 36 (see FIG. 7) and a position in contact with the first member 36 and pressed toward the first member 36 (see FIG. 8). Can be moved. That is, the second member 37 can advance and retract toward the first member 36. As the gripping mechanism 35 having such a configuration, for example, a one-touch gripping mechanism incorporated in a paper file can be employed. According to such a gripping mechanism 35, for example, by operating the lever with one hand, the sheet-like metal plate 10 is gripped by the gripping mechanism 35, and the sheet-like metal plate gripped by the gripping mechanism 35 is used. 10 can be released from the gripping mechanism 35.

  In the present embodiment, as can be understood from FIG. 2 and FIG. 9, when the support base material 40 is in the holding state, a pair of gripping mechanisms 35 fixed on the support base material 40 are connected. The straight line is not in contact with the surface of the support substrate 40. Therefore, the gripping mechanism 35 grips the metal plate 10 so as to be separated from the support base material 40 in the holding state. That is, the metal plate 10 held by the holding mechanism 35 is separated from the support base material 40.

  Next, the lid member 50 will be described. As shown in FIGS. 1 to 3 and 5, the lid member 50 has a flat plate shape. The lid member 50 has substantially the same outer contour as that of the support base member 40 in plan view. Then, the lid member 50 is disposed on the support base material 40 so as to sandwich the metal plate 10 with the support base material 40.

  As well shown in FIGS. 2 and 5, in order to prevent contact and interference between the gripping mechanism 35 attached on the support base material 40 and the lid member 50, the gripping mechanism 35 ( In other words, the interference avoiding portion 52 is formed at a position facing the grip portion 11) of the metal plate 10. The interference avoiding portion 52 may have a cutout shape as shown in FIG. 5, or may be formed as a recess, groove, hole, or the like. As well shown in FIGS. 2 and 3, the lid member 50 is formed with a recess 54 having a substantially rectangular opening shape. The concave portion 54 is formed in a region of the lid member 50 that faces the central portion 13 of the metal plate 10 when the metal plate 10 is gripped by the gripping mechanism 35 attached to the support base material 40. .

  As described above, the gripping mechanism 35 grips the metal plate 10 so as to be separated from the support base material 40 in the holding state (see FIG. 9). When the lid member 50 is overlaid on the support base material 40, the lid member 50 is placed on the metal plate 10 in a region between the region where the interference avoiding portion 52 is formed and the region where the concave portion 54 is formed. It comes into contact and presses. As a result, when the lid member 50 is superimposed on the support base member 40, the region 12 between the central portion 13 of the metal plate 10 held by the holding mechanism 35 and each holding portion 11 is pressed by the lid member 50. Then, it comes into contact with the support substrate 40.

  Similarly to the support base material 40, a groove 58 in which a binding means 33 for fixing the cover material 50 to the support base material 40 or the bottom material 60 is arranged on the side surface of the cover material 50. It is formed (see FIG. 5). When the lid member 50 is disposed at a predetermined position on the support base material 40, the groove 58 of the lid member 50 is aligned with the groove 48 of the support base material 40 as shown in FIG. 1.

  Next, the bottom material 60 will be described. As shown in FIGS. 1 to 3 and FIG. 6, the bottom member 60 has a flat plate shape. The bottom material 60 has substantially the same outer contour as the support base material 40 in plan view. The bottom material 60 is disposed on the side of the support base 40 opposite to the side on which the metal plate 10 is provided. When the bottom material 60 is superimposed on the support base material 40, the through hole 44 of the support base material 40 is covered with the bottom material 60.

  Similarly to the support base material 40, a groove 68 in which a bundling means 33 for fixing the bottom material 60 to the support base material 40 and the lid material 50 is disposed on the side surface of the bottom material 60. It is formed (see FIG. 6). When the bottom material 60 is disposed at a predetermined position on the support base material 40, the groove 68 of the bottom material 60 is aligned with the groove 48 of the support base material 40 as shown in FIG. 1.

  By the way, each of the support base material 40, the cover material 50, and the bottom material 60 may be formed from the same material, or may be formed from different materials. Specifically, each component of the packaging member 30 can be formed from paper, resin, metal, or a composite material containing any of these. Examples of the composite material include a material obtained by compressing and hardening chips such as chipboard paper, newspapers and magazines, or a material obtained by compressing and hardening wood waste. The binding means 33 can be a conventionally known fastening band or the like. It is also possible to use a rubber band as the bundling means 33.

  Next, a method for producing the package 70 by packing the metal plate 10 using the packaging member 30 having the above-described configuration will be described.

  First, the support base material 40 in which the gripping mechanism 35 is fixed to both end regions in the longitudinal direction is prepared. Next, the support member 40 is bent with the notch 42 of the support member 40 as a base point, and is deformed until it is in an attached state. That is, as shown in FIG. 7, the distance Lb between the pair of gripping mechanisms 35 is less than or equal to the length Lc along the metal plate 10 between the pair of gripping portions 11 of the metal plate 10 before being gripped by the gripping mechanism 35. The supporting substrate 40 is deformed until At this time, the support base material 40 having a flat plate shape is not only bent but also bent as shown in FIG.

  Then, as shown in FIG. 8, the gripping portion 11 of the metal plate 10 is gripped by the gripping mechanism 35 with the support base material 40 being deformed in this way. When the metal plate 10 is gripped by the gripping mechanism 35, it is not necessary to apply a force to the metal plate 10 to stretch the metal plate 10. Therefore, the metal plate 10 is easily and stably gripped by the gripping mechanism 35 fixed to the support member 40 while effectively preventing the metal plate 10 from being deformed by applying an excessive force to the metal plate 10. can do.

  After the pair of gripping portions 11 constituting both ends of the metal plate 10 are gripped by the pair of gripping mechanisms 35, it is not necessary to keep the support base material 40 in the attached state. Therefore, the force applied to maintain the support base 40 in the attached state is removed. Thereby, as shown in FIG. 9, the supporting base material 40 may be deformed from the attached state to the holding state by the restoring force of the supporting base material 40.

  Next, the lid member 50 is disposed on the side of the support base 40 on which the metal plate 10 is disposed. The lid member 50 is provided with an interference avoiding portion 52 at a position corresponding to the gripping mechanism 35. Therefore, the lid member 50 can be superimposed on the support base material 40 with the metal plate 10 interposed therebetween. Further, before the cover material 50 is overlaid on the support base material 40, after the cover material 50 is overlaid on the support base material 40, or in parallel with the cover material 50 being overlaid on the support base material 40, The bottom material 60 is disposed on the side of the support base 40 on which the metal plate 10 is not disposed, and the bottom material 60 is directly superimposed on the support base 40. In this way, when at least one of the lid member 50 and the bottom member 60 is superimposed on the support base material 40, the support base material 40 is maintained in a state of extending in a flat surface, that is, in a holding state. Deformation from the holding state to the mounting state is regulated.

  In this way, the support base material 40 holding the metal plate 10 via the gripping mechanism 35 is deformed from the attached state to the held state, and is maintained in the held state. When the supporting base material 40 is deformed from the attached state to the holding state, the separation distance between the pair of gripping mechanisms 35 of the supporting base material 40 becomes long. Accordingly, the metal plate 10 is stretched through the grip portion 11. However, as described above, the separation interval La between the pair of gripping mechanisms 35 in the holding state is equal to or less than the maximum length between the pair of gripping portions 11 of the metal plate 10 that can be deformed by elastic deformation. That is, the metal plate 10 gripped by the gripping mechanism 35 is held in an elastically deformed state at least between the pair of gripping portions 11 without being plastically deformed. Accordingly, a restoring force against elastic deformation acts between at least the pair of gripping portions 11 of the metal plate 10, and the metal plate 10 is restrained in a stretched state between the pair of gripping mechanisms 35. As a result, the metal plate 10 is fixed to the holding mechanism 35 and the support substrate 40 fixed to the holding mechanism 35.

  Further, as described above, the metal plate 10 held by the holding mechanism 35 is separated from the support base material 40. When the lid member 50 is superimposed on the support base member 40, the lid member 50 supports the region 12 between the central portion 13 of the metal plate 10 held by the holding mechanism 35 and each holding portion 11 by pressing. It comes to contact | abut to the base material 40 (refer FIG. 2). That is, the metal plate 10 is further pressed and extended by the lid member 50 in a state where the grip portion 11 is restrained by the grip mechanism 35. Thereby, the metal plate 10 is held between the support base material 40 and the lid member 50 in an extremely stable state, and is restrained from being moved or deformed.

  In this way, the lid member 50 and the bottom member 60 are superimposed on the support base member 40 holding the metal plate 10. Finally, the binding member 33 is used to fix the lid member 50 and the bottom member 60 to the support base member 40.

  According to the present embodiment as described above, the metal plate 10 is gripped by the gripping mechanism 35 in the pair of gripping portions 11 and held in an elastically deformed state. Therefore, the central portion 13 located between the pair of gripping portions 11 and including the perforated region 14 in which the holes 15 are formed can be restrained in the packing member 30. Thereby, even if the metal plate 10 has a large area and a thin thickness, and the metal plate 10 includes a perforated region 14 in which fine holes 15 are formed, the metal plate 10 may be damaged during handling. The metal plate 10 can be packed so as not to end up. In particular, in the present embodiment, the direction in which the metal plate 10 is elastically deformed, that is, the direction of the force applied to the metal plate 10 coincides with the longitudinal direction of the elongated hole 15. Therefore, it is possible to effectively prevent the perforated region 14 including the fine holes 15 from being damaged.

  Further, the support base 40 can be deformed into an attachment state in which the separation interval Lb between the pair of gripping mechanisms 35 is equal to or shorter than the length Lc between the pair of gripping portions of the metal plate 10 before being gripped by the gripping mechanism 35. . And in the state which deform | transformed the support base material 40 into the attachment state, the holding part 11 of the metal plate 10 can be hold | gripped by the holding mechanism 35. FIG. Therefore, when the metal plate 10 is gripped by the gripping mechanism 35, the metal plate 10 can be easily packed without being deformed by applying an excessive force.

  Further, according to the present embodiment, the concave portion 54 is formed in the region of the lid member 50 that faces the central portion 13 of the metal plate 10 gripped by the gripping mechanism 35. Therefore, the perforated region 14 of the metal plate 10 is in contact with the lid member 50 and effectively prevents, for example, damage to the perforated region 14 in which the fine holes 15 are formed by rubbing against the lid member 50. can do.

  Furthermore, according to the present embodiment, the through hole 44 is formed in the region of the support base 40 that faces the central portion 13 of the metal plate 10 gripped by the gripping mechanism 35. Therefore, it is effective that the perforated region 14 of the metal plate 10 is in contact with the support base material 40 and rubs against the support base material 40, for example, so that the perforated region 14 in which the fine holes 15 are formed is damaged. Can be prevented. Further, the through hole 44 of the support base material 40 is covered with a bottom material 60 that is superimposed on the support base material 40. That is, it is possible to prevent the central portion 13 (the perforated region 14) of the metal plate 10 from being exposed to the outside. As a result, during handling (for example, during transportation) of the package 70, the central portion 13 (the perforated region 14) is exposed to dust, foreign matter, etc., and the perforated region 14 in which the fine holes 15 are formed is damaged. Can be effectively prevented. Furthermore, since the through hole 44 is formed in the support base material 40 and is reinforced by the bottom material 60, the thickness of the support base material 40 can be reduced. Accordingly, the support base 40 can be easily deformed, and the metal plate 10 can be easily gripped by the gripping mechanism 35 without damaging the metal plate 10.

  Furthermore, according to the present embodiment, the lid mechanism is configured such that the gripping mechanism 35 grips the metal plate 10 so that the metal plate 10 is separated from the support base material 40 in the holding state, and is superimposed on the support base material 10. 50 presses the region 12 between the central portion 13 of the metal plate 10 gripped by the gripping mechanism 35 and each gripping portion 11 to contact the support substrate 40. As described above, according to the present embodiment, the metal plate 10 can be more stably and firmly restrained between the support base 40 and the lid member 50. Therefore, it is possible to more effectively prevent the metal plate 10 from being damaged. Further, the metal plate 10 can be elastically deformed by pressing with the lid member 50. Therefore, the amount of elastic deformation of the metal plate 10 before the lid member 50 is overlaid on the support base material 40 can be reduced. For this reason, the deformation amount from the holding state of the support base material 40 to the attached state can be reduced. Thereby, when the metal plate 10 is gripped by the gripping mechanism 35, it is possible to more effectively prevent the metal plate 10 from being deformed by applying an excessive force, and can be easily packed.

  Various modifications can be made within the scope of the gist of the present invention with respect to the above-described embodiment. Hereinafter, an example of a modification will be described.

  In the above-described embodiment, an example in which the lid member 50 presses the metal plate 10 that is gripped away from the support base material 40 toward the support base material 40 and makes contact with the support base material 40 is shown. However, it is not limited to this. For example, as shown in FIGS. 10 and 11, the lid member 50 may be disposed on the support base 40 so that the lid member 50 does not contact the metal plate 10. 10 and 11, the gripping mechanism 35 grips the metal plate 10 so that at least the central portion 13 of the metal plate 10 is separated from the supporting base material 40 in the holding state. Therefore, it is possible to prevent the perforated region 14 of the metal plate 10 from coming into contact with the support substrate 40 and being damaged without forming the through hole 44 in the support substrate 40.

  10 and 11 are cross-sectional views for explaining a modification of the packaging member and the package. The cross section shown in FIG. 10 corresponds to the cross section along the line XX in FIG. 11, and the cross section shown in FIG. 11 corresponds to the cross section along the line XI-XI in FIG. In the modification shown in FIG. 10 and FIG. 11, the same reference numerals are given to the same parts as those of the above-described embodiment, and the detailed description thereof is omitted.

  Further, in the above-described embodiment, the notch 42 is formed in the support base material 40, and the support base material 40 can be bent with the notch 42 as a base point. The cutout 42 may not be provided in the support base material 40. For example, the notch 42 may not be provided in the support base material 40, and the support base material 40 may be elastically deformable from the holding state to the attachment state without being bent. As an example, you may enable it to bend from the holding | maintenance base material 40 to an attachment state. In such an example, the metal plate 10 is elastically deformed until the distance Lc between the pair of gripping mechanisms 35 fixed to the supporting base material 40 in the holding state is the length Lc between the pair of gripping portions 11. If the restoring force of the support base material 40 deformed to the attached state is larger than the required force, the support member 40 is automatically moved from the attached state to the held state after the metal plate 10 is gripped by the gripping mechanism 35. Can return to the target. That is, the grasped metal plate 10 is automatically elastically deformed, and the metal plate 10 can be held in this state, whereby the metal plate 10 can be packed more easily.

  Furthermore, in the embodiment described above, an example in which the through hole 44 is formed in the support base material 40 has been described, but the present invention is not limited thereto. For example, a recess may be formed in the support base material 40 instead of the through hole 40. According to such a modification, the central portion 13 of the metal plate 10 can be blocked from the outside without providing the bottom material 60. That is, the bottom material 60 is not essential in the packaging member 30 and the package 70.

  Furthermore, according to embodiment mentioned above, although the package 70 showed the example containing only the metal plate 10 of 1 sheet, it is not restricted to this. The package 70 may include a plurality of metal plates 10. In this case, for the purpose of protecting the metal plate 10, an interleaving paper may be sandwiched between the metal plates 10.
