Description

  The present invention relates to a display filter package.

  For displays such as liquid crystal displays, plasma displays, and organic EL displays, the front surface is usually protected from reflection of external light, shielded from electromagnetic waves generated from the display, shielded from near-infrared rays generated from the display, and protection of the display. The intended display filter is installed. In particular, a display filter mounted on a plasma display is required to have a plurality of functions such as an electromagnetic wave shielding function, a near-infrared shielding function, an anti-reflection function, and the like. Generally, it is a laminated structure.

  Further, in recent years, so-called display direct attachment filters in which an adhesive layer for directly attaching a display filter to a display is previously laminated on the display filter side have become widespread. In the case of the above-mentioned direct filter for display, especially when a foreign substance enters between the display and the direct filter for display, it often becomes a fatal defect, so that the foreign substance does not adhere to the direct filter for display. It is necessary to strictly produce, pack and transport.

  Normally, in the production process of the display filter, the foreign matter is removed in the final inspection, but in the subsequent processes, the inspection is not performed until the display filter is attached to the display. Therefore, if foreign matter adheres to the display filter in the packaging or transportation process, the display filter once pasted to the display must be peeled off and another display filter must be pasted again, resulting in a significant cost increase. . Accordingly, there is a demand for a package that does not contain foreign matters in the packing and transportation process and does not generate foreign matters (such as generation of rubbing residue in the packing).

  Patent Documents 1 and 2 disclose a package that prevents the superposition of an optical film made of a polarizing film or the like (a product in which a plurality of optical films are stacked) from being deformed. Patent Document 1 discloses that an optical film superimposed material is fastened and fixed with a belt-like string ring, and then placed in an outer bag made of a plastic film and vacuum-sealed. Patent Document 2 discloses that after the optical film superimposed product is packaged with a packaging film that has been subjected to antistatic treatment, the overlapping edge surfaces of the packaging film are adhered with an adhesive tape having a high adhesive strength. It is described that the package is put in a polyolefin outer bag and packed in a cardboard box.

JP 2000-191994 JP 2007-55632 A

  In Patent Documents 1 and 2 described above, the optical film superimposed product is fixed so that it does not lose its shape with a belt-like string ring or packaging film and adhesive tape, but the optical film superimposed product is not fixed in the outer bag. It may move in the outer bag during transportation, and the fixed state of the optical film superimposed product may be loosened. In particular, a display filter mounted on a large screen such as a plasma display has a large weight per sheet, so that the fixed state of the optical film superimposed product is easily loosened due to movement in the outer bag during transportation. When the fixed state of the optical film superimposition is loosened, the optical films or the optical film and the packaging film rub against each other, and a new rubbing residue is generated in the package and reattaches to the optical filter.

  In addition, the method of strongly tightening and fixing the optical film superimposed material with a belt-like string ring as in Patent Document 2 is inappropriate for fixing the superimposed material of the display filter mounted on a large screen such as a plasma display. It is. That is, if the display filter superimposed product is strongly tightened with a belt-like string ring, there may be inconveniences such as bending of the display filter or bending of the end portion.

  In addition, since the display filter mounted on a large screen such as a plasma display is large in size and heavy in weight, the superposition of stacking such large display filters is easily bent due to its weight. Just wrapping with an interior film as in Literatures 1 and 2 does not allow easy insertion and removal from the outer bag, and the display filter may be bent or scratched due to the bending of the superimposed material. There is a case.

  Accordingly, an object of the present invention is to provide a display filter package that does not contain foreign matter and does not generate foreign matter. In particular, the present invention does not cause the superimposition of a display filter mounted on a large screen such as a plasma display to lose its shape during packing operation or transportation of the package, and to suppress generation of foreign matter due to rubbing or the like. Another object is to provide a display filter package.

  Another object of the present invention is to provide a package suitable for a direct-attachment filter for a display that is directly attached to a plasma display.

The above object of the present invention has been basically achieved by the following devices.

  ADVANTAGE OF THE INVENTION According to this invention, the package body of the filter for a display which does not mix a foreign material and does not produce a foreign material can be provided. In particular, according to the present invention, in a packing body of a display filter superimposition mounted on a large screen such as a plasma display, the superimposition does not lose its shape during packing operation or transportation of the packing body, and may be rubbed. It is possible to prevent new foreign matter from being generated in the package. Moreover, according to this invention, the package suitable for the direct pasting filter for a display directly affixed on a plasma display can be provided.

It is a top view of the other aspect of the accommodation bed used for this invention. It is a top view which shows an example when applying the accommodation bed of one size in this invention to the accommodation bed of a different size. It is the perspective view which illustrated the packaging form of the superposition thing by the film for interiors of the present invention. It is the perspective view which illustrated the packaging form of the superposition thing by the film for interiors of the present invention. It is a schematic side view of one embodiment of the packing body of the present invention. It is a perspective view which shows an example of the outer packaging case in which the packaging body of this invention is accommodated. FIG. 10 is a perspective view when the outer packaging case of FIG. 9 is stacked in a plurality of stages in the vertical direction.

  The present invention relates to a packaging body in which a superposed product in which a plurality of sheet-like display filters of the same size are stacked is packed. The number of display filters stacked to form such a superposed material is about 2 to 100, about 5 to 80 is appropriate, and about 10 to 60 is preferable. It is preferable that the weight of the superposed material on which the display filters are stacked is set to 50 kg or less at the maximum. If the weight of the superimposed material becomes too large, the display filter under the superimposed material will be too heavy, and scratches and dents are likely to occur, and the strength of the containment bed constituting the package must be excessively increased. There is a problem that the cost increases, and the superimposition cannot be carried manually. In the following description, a superimposed product in which a plurality of display filters are stacked is simply referred to as a superimposed product.

  The display filter in the present invention is a filter installed on a display screen of a display such as a plasma display, a liquid crystal display, or an organic EL display. This display filter is a filter having an antireflection function, an antiglare function, an electromagnetic wave shielding function, a near infrared shielding function, a color correction function, a display panel protection function, and the like.

  The present invention is suitable for a packing body of a filter for a display installed on a large screen (diagonal length of 30 inches or more = 762 mm or more) such as a plasma display. In particular, the diagonal length is 40 inches or more (1016 mm or more). It is suitable for a large size display filter package. The upper limit size of the display filter to which the present invention can be applied is about 100 inches (2540 mm) in diagonal length.

  The above-mentioned large-size display filters are heavy, weak, easily damaged, and extremely dislike foreign matter. could not.

  Therefore, as a result of intensive studies, it has been found that the above-described object is achieved by forming a package that is hermetically stored in an exterior bag in a state in which a superimposed object is accommodated in an accommodation bed having a bottom plate and a side plate, It came to make this invention.

Hereinafter, the packaging body of this invention is demonstrated in detail.
The accommodation bed in which the superimposed object is accommodated is formed of a bottom plate and a side plate, and has an accommodation space partially or entirely surrounded by the side plate. The planar shape of the display filter is usually rectangular, and the planar shape of the superimposed product of the display filter is also rectangular. Therefore, it is preferable that the storage space of the storage bed for storing the superimposed object is a rectangle slightly larger than the planar shape of the superimposed object.

  The bottom plate for forming the storage bed has a role of holding the superimposed object in a flat state so that the superimposed object stored in the storage bed does not bend, and the side plate prevents the superimposed object from moving in the horizontal direction. Has the role of holding. Therefore, the side plate is preferably disposed on each of the four sides of the rectangular accommodation space. In this case, the side plate may be disposed on the entire length of one side of the rectangular accommodation space, or the side plate may be disposed on a part thereof.

  FIG. 1 is a plan view showing an embodiment of a storage bed used in the packaging body of the present invention. The accommodation bed 1 is formed of a bottom plate 2 and side plates 3. FIG. 1A shows an aspect in which the side plate 3 is arranged on the entire outer periphery of a rectangular area (accommodating space 4) indicated by oblique lines. That is, in the embodiment of FIG. 1A, the side plate 3 is disposed over the entire length of the four sides of the accommodation space 4 indicated by hatching. FIG. 1B shows an aspect in which the side plate 3 is partially arranged on each of the four sides of the accommodation space 4 indicated by hatching. FIG. 1C shows an aspect in which the side plate 3 is disposed over the entire length of two opposing short sides of the accommodation space 4 indicated by hatching, and the side plate 3 is partially disposed over the two opposing long sides. is there.

  A feature of FIGS. 1B and 1C is that at least two corners of the accommodation space 4 in a diagonal relation are in an open state without being surrounded by side plates. That is, at least two corners in the diagonal relationship of the storage space 4 are not formed by the side plate. As described above, by opening at least two corners of the accommodation space 4 in a diagonal relationship, there is an advantage that the operation of accommodating and taking out the superimposed object from the accommodation bed is facilitated, which is a preferable aspect in the present invention. .

  Further, as shown in FIGS. 1B and 1C, it is more preferable that all the corners of the accommodation space 4 indicated by hatching are open. The containment bed used in the present invention can be used repeatedly, and in this case, dust and dirt adhering to the containment bed must be removed before reuse. Dust and dust tend to accumulate in the corners of the storage space and are difficult to remove. However, by opening all the corners of the storage space 4, the above problem can be solved.

  FIG. 2 is a perspective view of a preferred embodiment of a storage bed used in the packaging body of the present invention. The accommodation bed 1 is formed of a bottom plate 2 and side plates 3. The side plate 3 is partially disposed around the bottom plate 2 and is fixed to the bottom plate 2 with an adhesive, a double-sided adhesive tape, or the like. That is, in the mode of FIG. 2, the accommodation space 4 is formed by the side plates 3 that are partially arranged.

  FIG. 3 is a plan view of a bottom plate for forming the accommodation bed of FIG. The bottom plate 2 has protrusions 5 formed integrally with the accommodation space 4 on each of the four sides of the rectangular accommodation space 4 indicated by hatching. The protruding portion 5 of the bottom plate 2 abuts against the inner wall surface of the outer packaging case when the packaging body of the present invention is further stored in an outer packaging case described later, and the packaging body of the present invention moves within the outer packaging case. In addition to exhibiting the effect of preventing this, a space is created in the vicinity of the four corners of the outer packaging case where a finger can be inserted between the packaging body of the present invention, and the packaging body of the present invention is thereby made into the outer packaging case. Make work easier when storing and taking out from the outer packaging case.

  The shape of the protruding portion 5 of the bottom plate 2 is not particularly limited, and examples thereof include a rectangle, a square, a quadrangle such as a trapezoid, a triangle, a semicircle, and the like, and preferably a rectangle or a trapezoid.

  2 and 3, the protruding portion 5 of the bottom plate 2 is used as a mounting portion of the side plate 3 (an adhesive fixing portion of the side plate 3 to the bottom plate 2), and is a rectangle with diagonal lines surrounded by the four side plates 3. The area becomes the accommodation space 4.

  FIG. 4 is a plan view of another embodiment of the accommodation bed used in the present invention. FIG. 4A is a mode in which cutout portions 6 are provided so that fingers can be inserted into the four corners of the rectangular bottom plate 2. The meaning of providing the above-mentioned notch is to facilitate the work for storing the packing body of the present invention in the outer packing case and the work for taking out from the outer packing case as described above.

  In the embodiment of FIG. 4A, the notches 6 are provided at the four corners of the bottom plate 2. However, even when the notches are provided only at the two corners having a diagonal relationship, the purpose is as follows. Achieved.

  FIG. 4B shows an aspect in which the side plate 3 is provided inside the rectangular bottom plate 2 (the same as FIG. 1B). When storing the packing body using this storage bed in the outer packing case, by forming a recess where a finger can be inserted in the inner wall of the outer packing case, work when storing the packing body in the outer packing case, And the work when taking out from the outer packing case becomes easy.

  FIG. 5 is a plan view showing an example when one size of the storage bed is applied to a different size of the storage bed. FIG. 5A is a plan view of a storage bed applied to a relatively large display filter (A). 5 (b) and 5 (c) are storage beds applied to a display filter having a size smaller than that of the display filter (A). The storage bed applied to the display filter (A) is modified. This is the embodiment.

  5 (a), 5 (b), and 5 (c) are all the same size, and the size of the side plate 3 can be changed by changing the position of the side plate 3. It corresponds to the filter. That is, the position of the side plate 3 is adjusted in order to match the size of the superimposed object accommodated in the obliquely displayed accommodation space 4 (approximately the same size as the display filter). The bottom plate for forming the accommodation bed in FIG. 5 has the same configuration as the bottom plate in FIG. 3 described above.

  The embodiment of FIG. 5 is applied to a display filter of various sizes with a single size bottom plate, and by implementing this, various sizes can be obtained in one size outer packaging bag and one size outer packaging case. It is possible to deal with a display filter of a size, and as a result, there is an advantage that the inventory management work of the packing material is reduced because the types of the packing material are reduced by size.

  The bottom plate for forming the storage bed in the present invention has a role of holding the superposed material stored in the storage bed in a flat state so as not to bend, and a relatively high rigidity is required. From this viewpoint, as the material for the bottom plate, a plastic resin such as polypropylene resin, acrylic resin, polycarbonate resin, or the like, which is relatively light and relatively high in rigidity can be preferably used. The thickness of the bottom plate is preferably 3 mm or more, and more preferably 5 mm or more. The upper limit of the preferable thickness is about 20 mm.

  The side plate for forming the storage bed of the present invention has a role of holding the superposed material stored in the storage bed so as not to move in the horizontal direction, and is lightweight and requires a relatively high strength. From this viewpoint, a plastic resin foam is preferably used as a material for the side plate. Various foams are used as the plastic resin foam. Typical examples include polystyrene, polyethylene, polypropylene, polyvinyl chloride, polyurethane, melamine resin, phenol resin, and the like. Among these, a resin foam made of polystyrene, polyethylene, or polypropylene is preferably used. The expansion ratio of the plastic resin foam is preferably 5 to 35 times in order to obtain a relatively light weight and a relatively high strength. By using the above-mentioned plastic resin foam, there is an advantage that the weight can be greatly reduced without significantly reducing the strength as compared with a normal resin.

The height of the side plate is preferably about the same as the height of the superimposed object or slightly higher than the height of the superimposed object. An appropriate width of the side plate is about 5 to 50 mm.
The shape of the side plate is preferably a relatively long rectangular parallelepiped from the viewpoint of the role of the side plate and the workability of the side plate.

  In the present invention, the superimposition may be accommodated in the accommodation bed as it is, but preferably, the superimposition is accommodated in the accommodation bed in a state of being wrapped with the interior film. By packaging the superimposition with the film for interior, even if there is a slight gap between the superimposition and the side plate of the accommodation bed, slight movement of the superposition within the accommodation bed can be prevented. In addition, by packaging the overlay with an interior film, a part of the adhesive or adhesive contained in the adhesive layer drops off from the end face of the display filter overlay including the adhesive layer and reattaches to the display filter. This can be prevented.

Hereinafter, the aspect which wraps a superimposition with the film for interiors is demonstrated.
The material for the interior film is not particularly limited, and examples thereof include polyolefins such as polyethylene and polypropylene, polyamides such as nylon (registered trademark), polyesters such as polyethylene terephthalate, and polyvinyl chloride. About 10-100 micrometers is suitable for the thickness of the film for interior, and the range of 20-50 micrometers is preferable.

  The inner surface of the interior film (the surface that comes into contact with the superimposed material) is preferably subjected to release treatment. Thereby, it is possible to prevent a part of the pressure-sensitive adhesive and the adhesive contained in the adhesive layer from falling off due to the contact between the end face of the superimposed material and the inner surface of the interior film. For the release treatment, known release agents such as silicone release agents, long-chain alkyl release agents, fluorine release agents, and the like can be used.

The packaging form of the superposition thing by the film for interiors is demonstrated.
Although the example of this packaging form is shown in FIG. 6, FIG. 7, this invention is not limited to these. FIG. 6A shows a state in which the superimposed product 10 is wrapped with a single interior film sheet 7. FIG. 6B shows an aspect in which the superimposed product 10 is wrapped with two interior film sheets 7a and 7b. Reference numeral 8 denotes an adhesive tape.

  In FIG. 6B, the width of the interior film sheet 7 a is almost the same length as the long side of the superimposed product 10, and the width of the interior film sheet 7 b is almost the same length as the short side of the superimposed product 10. It is.

  FIG. 7 shows an aspect in which a dummy sheet 9 having the same size as the planar shape of the superimposed product is placed on the upper surface of the superimposed product, and is wrapped with an interior film sheet 7 from above. The embodiment shown in FIG. 7 is effective when an interior film sheet having an inner side surface subjected to mold release treatment is used. That is, it becomes possible to avoid the release agent from dropping off and reattaching to the superposed material when the superposed product comes into contact with the release treatment surface of the interior film sheet on the top surface of the superposed material by inserting the dummy sheet.

  Further, in the embodiment of FIG. 7, since the upper surface of the superimposed material is protected by the dummy sheet 9, it is not necessary for the interior film sheet 7 to cover the entire surface of the dummy sheet 9, and packaging is performed with the dummy sheet 9 exposed. Is possible. Reference numeral 8 denotes an adhesive tape. In the embodiment of FIG. 7, the interior film sheet may be an embodiment using only one sheet as shown in FIG. 6 (a), or two interior film sheets as shown in FIG. 6 (b). The mode used may be used.

  In the packaging form of FIG. 7, a general plastic film can be used as the dummy sheet inserted on the upper surface of the superposed material, but it is preferable to use an antistatic film sheet subjected to antistatic treatment. Can prevent dust and dirt from adhering.

  In this invention, the preferable aspect of the packaging form of the superposition thing by the film for interiors is the aspect which combined FIG.6 (b) and FIG. That is, a dummy sheet is inserted on the upper surface of the superimposition, and the two interior film sheets are wrapped so as to wrap the bottom and side surfaces of the superimposition, and the two interior film sheets are folded back on the upper surface of the superimposition. It is the aspect which packages so that only a part of may be covered.

  In the packaging form using the above two interior film sheets, it is not necessary to fold the corners of the overlapped object as in the form using one interior film sheet shown in FIG. It is easy and particularly effective when an interior film sheet having a relatively high strength is used. In general, a film having high strength is thick and strong, and therefore, in the case of a single interior film sheet, as described above, it is difficult to fold the corners of the superimposed material.

  Moreover, since it is not necessary to cover the entire upper surface of the superimposed product with the interior film sheet by using the dummy sheet, the length of the interior film sheet can be shortened, and the material cost can be reduced.

  As described above, it is preferable to use an antistatic film sheet as a dummy sheet. However, if a weak film such as polyethylene is used as the antistatic film sheet, the protection of the upper surface of the superimposed material is insufficient, or an interior film. There is a case where the antistatic film sheet is wrinkled during the bonding operation of the sheet with the adhesive tape. In order to avoid such a problem, it is preferable to insert a relatively stiff plastic film such as a polypropylene film or a polyester film between the antistatic film sheet and the interior film sheet.

  As described above, the interior film in the present invention preferably has a release treatment on the inner surface. However, when an interior film that has been subjected to a release treatment is used, a release treatment of the lower surface of the superimposed material and the interior film is performed. There may be a problem that the surfaces come into contact with each other and the release agent falls off and reattaches to the superposed material. In order to avoid this problem, it is preferable to insert a dummy sheet having substantially the same size as the lower surface of the superimposed material between the lower surface of the superimposed material and the interior film. A general plastic film can be used as the dummy sheet, but a defective display filter or a part of the constituent members of the display filter can be used as the dummy sheet.

  The dummy sheet inserted on the lower surface of the superimposed material is a film sheet that is relatively thick and heavy so that it does not stick to the display filter and lift up when the lowermost display filter is removed. Is preferably used. From this viewpoint, the thickness of the dummy sheet is preferably 100 μm or more, more preferably 150 μm or more, and particularly preferably 200 μm or more. The upper limit of the preferred thickness is about 1 mm.

  The superimposition (superimposition) wrapped with the interior film as described above is accommodated in the accommodation bed as described above. At this time, it is preferable to insert a cushioning sheet between the accommodation bed and the superimposed object. Examples of the cushioning sheet include a foamed resin sheet, a sponge sheet, and an air cushion sheet. The thickness of the cushioning sheet is suitably about 1 to 5 mm.

  The greatest feature of the present invention is that the superposed material is hermetically stored in the exterior bag in a state of being accommodated in the accommodation bed. Thereby, even if it is the superimposition of the display filter which is large in size and heavy, it is possible to prevent the superimposition from moving in the exterior bag. In addition, by sealing the exterior bag, it is possible to prevent dust and dust from entering the exterior bag from the outside.

  When the superimposed material moves in the exterior bag, even if the superimposed material is packaged with the interior film as described in Patent Documents 1 and 2, the large size and heavy weight of the superimposed display filter In such a case, the mold easily loses its shape, resulting in inconvenience that the superimposition is scratched or scrapes are reattached to the superimposition. Such a problem can be solved by the package of the present invention.

  Further, by storing the superimposition in the exterior bag in a state of being accommodated in the storage bed, it is possible to easily insert and store the superimposition of the large-sized and heavy display filter in the exterior bag. it can. It is quite difficult to insert and store only the superposed material in the exterior bag without using the storage bed.

  In the present invention, it is preferable that the superposed object is hermetically stored in a reduced pressure state in the exterior bag while being accommodated in the accommodation bed. To reduce the pressure inside the outer bag, insert a suction tube into the outer bag's insertion port, suck the air in the outer bag and bring it close to a vacuum state, heat seal the insertion port, etc. The closing method can be used.

  By setting the inside of the exterior bag to a reduced pressure state, it is possible to prevent the superposed material stored in the storage bed in the exterior bag from floating due to vibration during transportation. Moreover, since the oxygen and moisture in the exterior bag are greatly reduced by making the inside of the exterior bag in a reduced pressure state, adverse effects on the display filter due to oxygen and moisture can be reduced.

  It does not specifically limit as a material of an exterior bag, A well-known material can be used. For example, a material made of a plastic resin, a composite material of a plastic resin and a metal such as aluminum, and the like can be given. As a preferable material, for example, a material having at least two layers of a heat-sealable plastic resin and gas barrier and moisture-proof aluminum can be given.

  FIG. 8 is a schematic side view of one embodiment of the packing body of the present invention. In a state where the superimposed object 10 is accommodated in the accommodation bed 1, it is hermetically stored in the exterior bag 11 in a reduced pressure state.

  It is preferable that the packaging body of the present invention formed as described above is further stored in an outer packaging case. As the outer packaging case, for example, an outer packaging case 12 as shown in FIG. 9 can be used. Further, the outer packaging case 12 can be stacked in a plurality of stages in the vertical direction as shown in FIG.

  The package of the present invention is suitable for packaging a superposed product of a display filter mounted on a large screen such as a plasma display. Moreover, it is suitable for the packaging of the superimposition of the direct pasting filter for displays containing an contact bonding layer.

  The package of the present invention is suitable for packing a display filter having a diagonal length of 30 inches or more (762 mm or more), and particularly for a display filter having a diagonal length of 40 inches or more (1016 mm or more). Excellent packaging.

  The display filter in the present invention has at least one base film and at least one adhesive layer. The present invention is suitable for packing display filters that do not include a glass plate as a substrate.

  A known plastic film is used as the base film constituting the display filter in the present invention. For example, polyester resin films such as polyethylene terephthalate and polyethylene naphthalate, cellulose resin films such as triacetyl cellulose, polyolefin resin films such as polyethylene, polypropylene, and polybutylene, acrylic resin films, polycarbonate resin films, epoxy resin films, polyimide resin films, Examples include polyetherimide resin films, polyamide resin films, polysulfone resin films, polyphenylene sulfide resin films, and polyether sulfone resin films. Among these, a polyester resin film, a polyolefin resin film, and a cellulose resin film are preferable, and a polyester resin film is particularly preferably used. As thickness of a base film, the range of 50-300 micrometers is suitable, and the range of 90-250 micrometers is preferable.

  A known pressure-sensitive adhesive or adhesive is used for the adhesive layer constituting the display filter in the present invention, and the adhesive layer further contains a pigment or a dye for correcting the transmittance or color of the display filter. There is. The thickness of the adhesive layer is preferably about 10 to 50 μm.
