Description

Quilt package and package body

Technical Field

The present invention relates to a package and a package.

Background

Conventionally, a laminate in which a protective film is laminated on a main surface of a rectangular glass plate is known (for example, see patent document 1).

The protective film of the laminate of patent document 1 includes a 1 st edge overlapping or located inward of a pair of 1 st edges facing the glass plate and a 2 nd edge located outward of the other pair of 2 nd edges facing the glass plate in a plan view of the glass plate. Patent document 1 discloses the following: the protective films may be provided on both principal surfaces of the glass plate, and the end regions including the 2 nd edge may be bonded to each other.

Patent document 1: japanese patent laid-open publication No. 2017-171372

However, even if the end regions including the 2 nd edge are bonded to each other as described in patent document 1, the end face constituting the 1 st edge of the glass sheet is always exposed, and therefore, for example, when the laminate is packed in a vinyl plastic bag, particles generated by friction between the end face and the vinyl plastic bag may adhere to the end face during packing and transportation, and affect the subsequent steps.

Disclosure of Invention

The purpose of the present invention is to provide a package to be packaged and a package body that can prevent particles from adhering to a plate-shaped substrate.

A package body according to the present invention is housed in a housing member, and the package body includes: a laminate having a plate-like base and a protective film disposed on at least one of a pair of main surfaces of the plate-like base; and a pair of protective plates disposed so as to sandwich the laminate from both sides of the pair of main surfaces, wherein at least a part of outer edges of the protective plates is located outside the outer edges of the plate-shaped substrates, and the entire outer edges of the pair of protective plates are located outside the outer edges of the laminate.

According to the present invention, the laminate having the plate-like base body in which the protective film is disposed on at least one of the main surfaces is sandwiched by the pair of protective plates, and the entire outer edges of the pair of protective plates are located outside the outer edge of the laminate. Therefore, when the package body is housed in the housing member, the housing member is a bag body, the bag body is disposed so as to span between the outer edges of the pair of protection plates, and when the housing member is a case, the inner peripheral surface of the case is formed in a straight line shape connecting the outer edges of the protection plates to each other or in a substantially straight line shape at a position apart from the outer edges of the protection plates, and a gap can be formed between the inner peripheral surface of the housing member and the outer edges of the protection plates. Therefore, friction between the housing member and the protective film can be reduced, and adhesion of particles to the plate-like base body due to the friction can be reduced.

In the package body according to the present invention, it is preferable that the package body further includes a fixing member for fixing the pair of protection plates to the stacked body.

In this aspect of the present invention, the positional displacement of the stacked body with respect to the protective plate can be suppressed when the package body is conveyed.

In the package according to the present invention, it is preferable that the fixing member includes a band-shaped, string-shaped, or annular winding member wound around the stacked body and the pair of protection plates.

In this aspect of the present invention, the fixing of the two is facilitated by a simple method of winding only the band-shaped, string-shaped, or annular winding member around the stacked body and the pair of protective plates.

In the fixing of both end portions in the longitudinal direction of the band-shaped or string-shaped winding member, an appropriate method such as the connection of both end portions of the winding member, the fixing by a buckle, the adhesion, and the fusion can be used depending on the shape and material of the winding member.

In the package body according to the present invention, it is preferable that at least one of the pair of protective plates is configured to be deformable by a winding force of the winding member.

In this aspect of the present invention, the protection plate is bent along the outer edge of the plate-shaped base, and the plate-shaped base can be prevented from being displaced in the surface direction of the protection plate.

In the package according to the present invention, it is preferable that the at least one protective plate has a corrugated plate structure including a corrugated plate-shaped core and a liner plate provided on at least one surface of the core, and the wound member is wound such that an angle formed between a longitudinal direction of the wound member and a ridge line direction of the core is 0 ° or more and 30 ° or less.

In this aspect of the present invention, the protection plate can be prevented from buckling along the ridge line of the center core, and the breakage of the protection plate can be prevented.

In the package according to the present invention, the at least one of the protection plates has a corrugated plate structure including a corrugated plate-shaped core and a backing plate provided on at least one surface of the core, the laminate and the pair of protection plates are wound with a 1 st winding member and a 2 nd winding member, the 1 st winding member is wound such that an angle formed between a longitudinal direction of the 1 st winding member and a ridge line direction of the core is 0 ° or more and 30 ° or less, and the 2 nd winding member is wound such that an angle formed between a longitudinal direction of the 2 nd winding member and a longitudinal direction of the 1 st winding member is 50 ° or more and 90 ° or less.

In this aspect of the present invention, since the protective plate is slightly deflected by the 1 st winding member along the line intersecting the ridge line of the center core, even if the 2 nd winding member is wound so that the angle formed between the longitudinal direction thereof and the 1 st winding member is 50 ° or more and 90 ° or less, the protective plate can be suppressed from buckling along the ridge line of the center core due to the effect of the geometric rigidity, and the breakage of the protective plate can be suppressed.

In the package of the present invention, it is preferable that the corner portions of the pair of protective plates are formed to be obtuse angles or curved lines when viewed from the main surface side of the plate-shaped base.

In this aspect of the invention, it is possible to prevent the corner of the protective plate from being damaged or the accommodating member from being cut when the package body is accommodated in the accommodating member.

In the package body according to the present invention, it is preferable that the package body further includes a contact suppressing member provided between the laminate and the pair of protective plates.

In this aspect of the present invention, for example, when the package is transported, the plate-shaped base is prevented from being damaged due to the collision between the portion of the plate-shaped base not protected by the protective film and the protective plate.

In the package of the present invention, it is preferable that the contact suppressing member has a function of suppressing sliding between members in contact with the contact suppressing member, and the contact suppressing member is provided between the stacked bodies.

In this aspect of the present invention, for example, when the package is transported, the sliding between the stacked body and the protective plate and between the stacked bodies can be suppressed, and the plate-shaped base can be prevented from being damaged by collision with another member.

In the package of the present invention, it is preferable that protective films are respectively disposed on both main surfaces of the plate-shaped base, and at least a part of an end region of one of the protective films located outside an outer edge of the plate-shaped base does not contact an end region of the other protective film.

In the laminate according to this aspect of the present invention, both main surfaces of the plate-like substrate can be protected by the protective film. Further, since the end region of at least a part of one protective film does not contact the end region of the other protective film, the protective film can be easily peeled by gripping the non-contacting end region. In addition, in the package of the present invention, even with the laminate having such an effect, friction between the storage member and the protective film can be suppressed, and adhesion of particles to the plate-shaped base can be prevented.

In the package body of the present invention, the plate-like substrate is preferably glass.

In this aspect of the present invention, glass having both high strength and good texture and having brittleness can be reliably packed.

In the packaged body of the present invention, the glass is preferably a tempered glass.

In this aspect of the present invention, glass having both high strength and good texture and having brittleness can be reliably packed. Further, although the cracks exceeding the compressive stress layer affect the strength reduction of the tempered glass, the occurrence of such cracks can be suppressed.

The package body of the present invention includes the package body and a housing member for housing the package body.

In this aspect of the invention, the package body can be transported while preventing the laminate from being exposed to the external atmosphere.

In the package of the present invention, the storage member is preferably a resin bag.

In this aspect of the present invention, the package body can be made lightweight.

Detailed Description

[ embodiment ]

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[ body of a bag ]

As shown in fig. 1 and 2, the package 1 includes a plurality of stacked bodies 2, a plurality of contact suppressing members 3, a pair of protective plates 4, and a pair of fixing members 5.

The laminate 2 includes: a plate-like substrate 21 having a 1 st main surface 21A, a 2 nd main surface 21B, and an end surface 21C; a 1 st protective film 22 disposed on the 1 st main surface 21A; and a 2 nd protective film 23 disposed on the 2 nd main surface 21B.

The thickness of the plate-like substrate 21 is preferably 0.5mm to 2.5 mm. The plate-like base 21 is preferably glass having both high strength and good texture and having brittleness. When the plate-like substrate 21 is made of glass, it is preferably tempered glass having excellent strength and abrasion resistance.

An antireflection layer, not shown, is preferably provided on the 1 st main surface 21A of the plate-like substrate 21. The antireflection layer is preferably provided on the entire 1 st main surface 21A.

Further, an anti-contamination layer, not shown, is preferably provided on the 1 st main surface 21A of the plate-shaped substrate 21 with or without an anti-reflection layer interposed therebetween. The anti-contamination layer is preferably provided on the entire 1 st main surface 21A.

In addition, functional layers such as an anti-glare layer and an anti-fog layer may be provided on the 1 st main surface 21A in addition to or instead of at least one of the anti-reflection layer and the anti-pollution layer.

A printed layer, not shown, is preferably provided on the 2 nd main surface 21B of the plate-like substrate 21. The printed layer is preferably provided in a frame shape having a predetermined width including the outer edge of the 2 nd main surface 21B when the plate-shaped substrate 21 is used as cover glass of a display panel. The printed layer may be a hidden layer that hides the wiring of the display panel on which the plate-shaped substrate 21 is provided, or may be a decorative layer that improves the design of the plate-shaped substrate 21.

The end face 21C of the plate-like base 21 is preferably chamfered.

The 1 st and 2 nd

protective films

22 and 23 are formed such that at least a part of the outer edge is positioned outside the outer edge of the plate-like base 21.

The 1 st protective film 22 preferably includes a 1 st film base 22A, a 1 st adhesive layer 22B provided on one surface of the 1 st film base 22A, and a protruding piece 22C.

The 1 st film substrate 22A is formed in a rectangular shape smaller than the 1 st main surface 21A of the plate-like substrate 21. The protruding piece 22C is provided such that a part thereof is positioned within the surface of the 1 st film base 22A and the remaining part protrudes outward from one side edge of the 1 st film base 22A. The protruding length of the protruding piece 22C protruding from the 1 st film base 22A is preferably 0.2mm to 10mm, and more preferably 0.5mm to 3 mm. Within this range, the projecting piece 22C does not contact the 2 nd protective film 23, and the projecting piece 22C can be easily gripped to peel the 1 st film base 22A. The protruding piece 22C is preferably detachable from the 1 st film base 22A via an adhesive layer not shown, for example. Alternatively, one film base having an outer shape in which the protruding piece 22C portion and the 1 st film base 22A are combined may be used.

The 2 nd protective film 23 preferably includes a 2 nd film base 23A and a 2 nd adhesive layer 23B provided on one surface of the 2 nd film base 23A.

The 2 nd film substrate 23A is formed in a rectangular shape larger than the 2 nd main surface 21B of the plate-like substrate 21.

The 1 st protective film 22 is preferably such that the entire outer edge of the 1 st film base 22A is located inward of the outer edge of the plate-like base 21, and a part of the protruding piece 22C protrudes from the outer edge of the plate-like base 21. In a region where the outer edge of the 1 st film base 22A is located inward of the outer edge of the plate-like base 21, the distance from the outer edge of the plate-like base 21 to the outer edge of the 1 st film base 22A is preferably 3mm or less, and more preferably 1mm or less. This is because if the thickness exceeds 3mm, the possibility of in-plane contamination increases.

The 2 nd protective film 23 is preferably formed such that the entire outer edge of the 2 nd film base 23A is located outside the outer edge of the plate-like base 21.

In the 1 st and 2 nd

protective films

22 and 23 having such a structure, it is preferable that at least a part of the end region of one protective film is not in contact with the end region of the other protective film, and the end face 21C is exposed.

From the viewpoint of ease of obtaining a material, the 1 st and 2

nd film substrates

22A and 23A are preferably made of PET or PE. In addition, the static friction coefficient between the 1 st film substrate 22A and the 2 nd film substrate 23A is preferably 0.05 to 0.15 from the viewpoint of reducing the sliding of one laminated body 2 with respect to the other laminated body 2.

The main component of the 1 st and 2 nd

adhesive layers

22B and 23B is preferably an acrylic resin or a urethane resin from the viewpoint of adhesiveness and peelability, and more preferably a urethane resin from the viewpoint of suppressing the generation of air bubbles between the 1 st and 2 nd

protective films

22 and 23 and the 1 st and 2 nd

main surfaces

21A and 21B.

The 1 st and 2 nd

protective films

22 and 23 may be of the same shape and material, or of different structures. For example, from the viewpoint of reducing the possibility of the pasted surface being mistaken, the shapes of the 1 st and 2 nd

protective films

22 and 23 are more preferably different.

The contact suppressing member 3 is disposed so as to sandwich the stacked body 2. The contact suppressing member 3 is formed in a square plate shape. The contact suppressing member 3 is preferably large enough that the entire outer edge thereof is located outside the outer edge of the laminate 2. The material of the contact suppressing member 3 is not particularly limited as long as the contact of the laminate 2 with the protective plate 4 can be suppressed.

Examples of the contact suppressing member 3 include Miramat (manufactured by JSP corporation, registered trademark)), insert paper (kirrari (registered trademark), manufactured by chandelian paper corporation), and a foamed polypropylene sheet, which are high-foaming polyethylene sheets.

The contact suppressing member 3 is preferably disposed between the stacked bodies 2 in order to suppress contact between the stacked bodies 2. The contact preventing member 3 preferably has an effect of preventing sliding, and from this viewpoint, is preferably a highly foamed polyethylene sheet. The contact suppressing member 3 may be made of the same material as the 1 st and 2 nd

protective films

22 and 23. That is, the contact suppressing member 3 may include a film made of PET or PE, and an adhesive layer made of an acrylic resin or a urethane resin.

The protective plate 4 is disposed so as to sandwich the stacked body 2 stacked in plural through the contact suppressing member 3. The protection plate 4 is formed in an octagonal plate shape in which four corners of a quadrangular plate shape are cut off in a plan view. The angle of the 8 corners of the protection plate 4 becomes an obtuse angle (135 °).

The protective plate 4 has a size such that the entire outer edge thereof is located outside the outer edge of the laminate 2. The protective plate 4 is preferably of the following size: when the protective plate is disposed so that the center thereof overlaps the centers of the 1 st and 2

nd film bases

22A and 23A in a plan view, the distance from the outer edge of the protective plate 4 to the projecting tip of the projecting piece 22C and the distance from the outer edge of the protective plate 4 to the outer edge of the 2 nd film base 23A are 5mm to 5 cm. If the thickness is less than 5mm, the protective plate 4 may be displaced from the center of the laminated body 2, which may increase the possibility that the laminated body 2 may protrude from the protective plate 4. If it exceeds 5cm, there is a possibility that only the portion of the protective sheet 4 may be bent by an unexpected load from the outside, and the necessary protective bag and package may become unnecessarily large. The protective plate 4 includes a pair of 1 st side portions 4A corresponding to the pair of mutually opposed sides of the quadrangular plate shape, and a pair of 2 nd side portions 4B orthogonal to the pair of 1 st side portions 4A.

The protective plate 4 is preferably deformable when the fixing member 5 is wound around the protective plate 4, the laminated body 2, and the contact suppressing member 3. From the viewpoint of such deformation, the flexural modulus of the protective plate 4 is preferably 5N/cm or more and 500N/cm or less. When the difference in the flexural modulus occurs depending on the direction, the larger flexural modulus is indicated. The thickness of the protective plate 4 is preferably 2mm to 5 mm.

The protection plate 4 of the present embodiment has a corrugated plate structure as follows: the corrugated plate-like core 41 and the lining plates 42 provided on at least both surfaces of the core 41 are provided. The protective plate 4 having a corrugated structure may be made of resin or paper, but is preferably made of resin from the viewpoint of durability. The protective plate 4 may be disposed between the stacked bodies 2.

The fixing member 5 fixes the pair of protective plates 4 to the stacked body 2. As shown in fig. 2, the fixing member 5 is composed of a 1 st rubber band 5A as a 1 st winding member and a 2 nd rubber band 5B as a 2 nd winding member.

The fixing member 5 is not particularly limited if it is a member having a winding force. For example, as shown in fig. 3, a tightening band 50 or the like as a winding member having a band portion 51 and a buckle 52 may be used, or may be fixed by welding the band portion 51. The material, width, or thickness of the band 51, and the material or type of the buckle 52 are not particularly limited, and may be appropriately selected according to the size and weight of the laminate 2. The tape portion 51 may be a resin tape portion such as a PP tape or a cloth tape portion.

The package 1 is manufactured as follows using the laminate 2, the contact suppressing member 3, the protective plate 4, and the fixing member 5 as described above.

The following operations may be performed by the apparatus, all of the operations may be performed by manual operations of an operator, or a part of the operations may be performed by the apparatus or the operator. In addition, a plurality of operations may be performed simultaneously.

First, the contact suppressing member 3 is placed on the protective plate 4. The contact suppressing member 3 is preferably placed so that the center thereof overlaps the center of the protective plate 4 and the entire outer edge thereof is located inward of the outer edge of the protective plate 4.

Further, on the contact suppressing member 3, the plurality of stacked bodies 2 and the contact suppressing member 3 are sequentially placed in the order of the stacked body 2 and the contact suppressing member 3. At this time, the stacked body 2 is placed so that the entire outer edge of the stacked body 2 is located inside the outer edge of the protective plate 4. The laminate 2 and the contact suppressing member 3 are preferably placed so that the centers thereof overlap the center of the protective plate 4. The number and weight of the stacked bodies 2 are not particularly limited, but it is preferable that the stacked bodies 2 are set so as not to be displaced with respect to the protective plate 4 by an inertial force when the package 1 is transported in the surface direction of the plate-shaped base 21 and stopped, or by a gravity force when the package 1 is placed vertically (when the package 1 is placed so that the surface direction of the plate-shaped base 21 is parallel to the vertical direction), or so as not to position the entire outer edge of the 2 nd protective film 23 outside the outer edge of the protective plate 4 even if the outer edge is displaced.

Then, the protective plate 4 is placed on the uppermost contact suppressing member 3. At this time, the protective plate 4 is placed on the contact suppressing member 3 such that the direction of the upper protective plate 4 along the ridge line 41A of the core 41 (hereinafter, referred to as the ridge line direction) is parallel to the ridge line direction of the lower protective plate 4. The protective plate 4 is preferably placed so as to overlap the protective plate 4 positioned below the stacked body 2 in a plan view.

Next, the 1 st and 2

nd rubber bands

5A and 5B are wound around the laminate 2, the contact suppressing member 3, and the protective plate 4. At this time, as shown in fig. 2, the 1 st rubber band 5A is wound so that an angle θ 1 formed between the longitudinal direction of the 1 st rubber band 5A indicated by a two-dot chain line and the ridge line direction is 0 ° to 30 °. In the present embodiment, as shown by the solid line in fig. 2, the 1 st rubber string 5A is wound around the center portion of the long side of the protective plate 4 so that the long side direction of the 1 st rubber string 5A is parallel to the short side direction of the protective plate 4, that is, so that θ 1 is 0 °. The 2 nd elastic band 5B is wound so that an angle θ 2 formed between the longitudinal direction of the 1 st elastic band 5A and the longitudinal direction of the 2 nd elastic band 5B is 50 ° to 90 °. In the present embodiment, the 2 nd rubber band 5B is wound around the center portion of the short side of the protective plate 4 so that the longitudinal direction of the 2 nd rubber band 5B is parallel to the longitudinal direction of the protective plate 4, that is, so that θ 2 is 90 °.

The total tension of the 1 st and 2

nd rubber bands

5A and 5B wound as described above is preferably 10N to 80N.

In the case of less than 10N, the fixing force is insufficient to cause the stacked body 2 to shift. If the number exceeds 80N, the protection plate 4 may bend, and the protection plate 4 may strongly contact the 1 st and 2

nd rubber bands

5A and 5B, thereby damaging the protection plate 4. The total tension of the 1 st and 2

nd rubber bands

5A and 5B is more preferably 15N or more, and still more preferably 20N or more. The total tension of the 1 st and 2

nd rubber bands

5A and 5B is preferably 60N or less, and more preferably 50N or less.

At this time, as shown in fig. 5, the portion of the protection plate 4 located outside the plate-like base body 21 is slightly deflected along a line intersecting the ridge line 41A of the core 41 by the 1 st rubber band 5A. Therefore, as shown in fig. 4, even if the second rubber band 5B is hung so that the angle formed by the longitudinal direction thereof and the ridge line 41A is 90 °, the portion of the protection plate 4 located outside the plate-like base body 21 can be suppressed from being largely deflected along the ridge line 41A due to the effect of the geometric rigidity.

The production of the package body 1 is completed by the above operation.

In the case of using the fastening tapes 50, as shown in fig. 3, the tape parts 51 of the two fastening tapes 50 are first placed on the work table in parallel with a predetermined gap therebetween, and then the protective plate 4 is placed thereon. At this time, the rubber band is placed so that the angle formed by the ridge line direction and the longitudinal direction of the belt portion 51 is 0 ° to 30 ° as in the case of the 1 st rubber band 5A.

Thereafter, as in the case of using the 1 st and 2

nd rubber bands

5A and 5B, the laminate 2, the contact suppressing member 3, and the protective plate 4 are placed, and the tape portion 51 is wound around the laminate 2, the contact suppressing member 3, and the protective plate 4, and both ends thereof are fixed by the buckle 52. Then, the end 51A of the belt portion 51 on the side where the buckle 52 is not provided is pulled from the position shown by the two-dot chain line in fig. 3 to the position shown by the solid line to fasten the belt portion 51. The total tension of the belt portion 51 is preferably 10N to 80N.

At this time, as shown in fig. 6, the 1 st side edge portion 4A of the protective plate 4 not in contact with the tape portion 51 is not deformed. In addition, since the 1 st side portion 4A is not deformed, the portion of the contact preventing member 3 and the 2 nd protective film 23 on the 1 st side portion 4A side is also hardly deformed.

On the other hand, as shown in fig. 7, the protective plate 4 in contact with the band portion 51 is slightly deflected along a line intersecting the ridge line 41A of the core 41 by the winding force of the band portion 51. Due to the deflection of the 2 nd side edge portion 4B, the portion of the contact suppressing member 3 and the 2 nd protective film 23 on the 2 nd side edge portion 4B side is also slightly deflected along the outer edge of the plate-like base 21.

[ Package body ]

Next, a package body having the package body 1 will be explained.

As shown in fig. 4 and 5, or fig. 6 and 7, the package body 10 includes: a bag body 11 as a housing member for housing the packaged body 1; a rectangular box-shaped case 12 for accommodating the bag 11; and a cushion member 13 provided between the bag body 11 and the case body 12.

The bag body 11 is made of, for example, a transparent or colored vinyl bag. As such a bag body 11, a folded bag can be exemplified.

The case 12 is made of, for example, corrugated board, and includes a main body 12A having an open upper surface, and a pair of covers 12B provided on opposite sides of the upper surface. The cover 12B may be fixed by an adhesive tape or a tape. The case 12 may be made of resin.

In addition, the cushion member 13 may be omitted.

[ Effect of the embodiment ]

The laminate 2 having the 1 st and 2 nd

protective films

22 and 23 disposed on the 1 st and 2 nd

main surfaces

21A and 21B of the plate-like base 21 is sandwiched between the pair of protective plates 4, and the entire outer edges of the pair of protective plates 4 are positioned outside the outer edges of the laminate 2.

Therefore, when the package 1 is stored in the bag body 11, the bag body 11 is disposed so as to bridge the outer edges of the pair of protective plates 4, and a gap can be formed between the bag body 11 and the outer edges of the 1 st and 2 nd

protective films

22 and 23. Therefore, friction between the bag 11 and the 1 st and 2 nd

protective films

22 and 23 can be suppressed, and particles generated by the friction can be prevented from adhering to the plate-shaped base 21.

Since the protection plate 4 is fixed to the stacked body 2 by the fixing member 5, the positional displacement of the stacked body 2 with respect to the protection plate 4 can be suppressed when the package 1 is transported.

In particular, since the 1 st and 2

nd rubber bands

5A and 5B are used as the fixing members 5, the 1 st and 2

nd rubber bands

5A and 5B can be fixed by a simple method of merely winding the 1 st and 2

nd rubber bands

5A and 5B around the stacked body 2 and the protective plate 4.

The 2 nd protective film 23, the contact suppressing member 3, and the protective plate 4 are bent along the outer edge of the plate-like base 21 by the winding force of the 1 st and 2

nd rubber bands

5A and 5B, and therefore, positional displacement in the left-right direction in fig. 4, 5, and 7 of the laminate 2 can be suppressed by the bending.

In addition, in the case of using the fastening tape 50, since the angle formed by the ridge line direction of the core 41 of the protective plate 4 and the longitudinal direction of the tape portion 51 is set to 0 °, the 2 nd side edge portion 4B of the protective plate 4 is bent along a line orthogonal to the ridge line 41A. Therefore, compared to the case where the 1 st side edge portion 4A of the protection plate 4 is bent along the ridge line 41A, breakage of the protection plate 4 can be suppressed.

Since the corner of the protective plate 4 is formed to be an obtuse angle in a plan view, damage to the corner of the protective plate 4 and cutting of the bag body 11 can be suppressed.

Since the contact suppressing members 3 are provided between the stacked body 2 and the protective plate 4 and between the stacked bodies 2, the stacked body 2 can be prevented from sliding with respect to the protective plate 4 or another stacked body 2 during transportation or vertical placement of the package 1. Therefore, it is possible to prevent particles generated by friction between

bag

11 and 1 st and 2 nd

protective films

22 and 23 from adhering to plate-shaped base 21 and prevent plate-shaped base 21 from colliding with a floor or the like and being damaged.

Since the end region of at least a part of the 1 st protective film 22 is not in contact with the end region of the 2 nd protective film 23, the 1 st and 2 nd

protective films

22 and 23 can be easily peeled off by gripping the portions of the projecting

pieces

22C and 2 nd protective film 23 which are positioned outside the outer edge of the plate-like base body 21. Even with the laminate 2 having such an effect, the friction between the bag 11 and the 1 st and 2 nd

protective films

22 and 23 can be suppressed, and the adhesion of particles to the plate-like base 21 can be prevented.

[ modified examples ]

The present invention is not limited to the above-described embodiments, and various modifications, design changes, and the like can be made without departing from the scope of the present invention.

[ modification of the body to be packaged ]

For example, the laminate 2 may have a structure in which the 1 st protective film 22 or the 2 nd protective film 23 is disposed only on one surface of the plate-shaped substrate 21, or may have a structure in which only the 1 st protective film 22 or the 2 nd protective film 23 is disposed on both surfaces of the plate-shaped substrate 21.

In the present modification or the above-described embodiment, there may be one laminated body 2 constituting the package body.

The contact suppressing member 3 may be disposed only between the upper laminated body 2 and the protective plate 4 or between the lower laminated body 2 and the protective plate 4, or the contact suppressing member 3 may not be disposed at all.

The contact suppressing member 3 may be disposed between the plate-like base 21 and the plate-like base 21, or between the 1 st protective film 22 or the 2 nd protective film 23 and the plate-like base 21.

The corner of the protection plate 4 may be curved in a plan view, and the entire shape of the protection plate 4 may not be octagonal as long as it is an obtuse angle. In this case, it is also possible to prevent the corners of the protective plate 4 from being damaged or to cut the bag body 11.

The corner of the protective plate 4 may be a right angle or an acute angle in a plan view, and in this case, the receiving member that contacts the protective plate 4 is preferably configured to be not damaged or cut by the contact.

At least one of the pair of protection plates 4 may be formed of a material that is not deformed, and may not have a corrugated plate structure.

The protective plate 4 may be positioned so that the angle formed by the ridge line direction and the longitudinal direction of the band portion 51 is 90 °, and in this case, it is preferable that the protective plate 4 is configured so as not to break when it is bent in the ridge line direction.

In addition, when the plate-shaped base 21 is curved, the protection plate 4 may have a shape curved along the shape of the laminated body 2 as shown in fig. 8. Thus, the displacement of the plate-like base 21 can be more effectively suppressed. The protective plate 4 can be formed by molding a foamed resin sheet, for example.

The end of the protective plate 4 may also be bendable. As shown in fig. 9, by bending the end portion of protective plate 4, contact between plate-shaped base 21 and bag 11 can be further suppressed. In this case, it is preferable that the end portion of the protection plate 4 is not bent when the plate-shaped base 21 is placed, and the end portion of the protection plate 4 is bent after the plate-shaped base 21 is placed. Further, when the side surface portions of the laminate 2 are held when the plate-like substrate 21 is placed, the main surface of the laminate 2 is preferably held by suction or sandwiching due to the rolling or rubbing of the protective film 22. In this case, when the plate-like base 21 is placed, the stacked bodies 2 can be stacked in the lateral direction. After the plate-shaped substrate 21 is placed, if the end portion of the protective plate 4 is bent in order to protect the side surface portion of the laminated body 2, the adhesion of particles to the plate-shaped substrate 21 can be further suppressed.

The 1 st elastic band 5A or the 2 nd elastic band 5B may not be hung, or another elastic band may be further hung beside the 1 st elastic band 5A or the 2 nd elastic band 5B.

The fastening band 50 is formed of a fastening band having a band portion 51 and a buckle 52, but may be formed of a band-shaped or string-shaped winding member, and both end portions of the winding member may be connected, bonded, fused, or the like to be fixed.

Adhesive tape may also be used as the fixing member.

[ modification of package body ]

The package body 1 to be packaged, which is housed in the bag body 11, is housed in the case 12, but may not be housed in the case 12.

Even in this case, the bag body 11 may be made of paper or cloth, and the protective plate 4 can suppress friction between the bag body 11 and the 1 st and 2 nd

protective films

22 and 23, thereby preventing particles generated by the friction from adhering to the plate-shaped base 21. The bag body 11 may be configured by winding a sheet-like member made of resin, paper, or cloth around the package body 1.

The package body 1 may be stored in the case 12 without being stored in the bag body 11, and in this case, the case 12 corresponds to the storage member of the present invention.

[ other modifications ]

< plate-like substrate >

The application of the plate-like substrate of the present invention is not particularly limited. Specific examples thereof include transparent members for vehicles (e.g., front cover, rear mirror, front transparent substrate, side transparent substrate, rear transparent substrate, instrument panel surface), measuring tools, architectural windows, showcases, interior building components, exterior building components, displays (e.g., notebook computers, monitors, LCDs, PDPs, ELDs, CRTs, and PDAs), LCD color filters, touch panel substrates, pickup lenses, optical lenses, spectacle lenses, camera components, video camera components, CCD cover substrates, optical fiber end surfaces, projector components, copier components, transparent substrates for solar cells (e.g., cover glasses), mobile phone windows, backlight unit components (e.g., light guide plates and cold cathode tubes), backlight unit liquid crystal brightness enhancement films (e.g., prisms and semi-transparent films), liquid crystal films, organic EL light-emitting element components, inorganic EL light-emitting element components, and the like, A phosphor light-emitting element member, an optical filter, an end face of an optical member, an illumination lamp, a cover of an illumination device, an amplified laser light source, an antireflection film, a polarizing film, an agricultural film, and the like.

The shape of the plate-like base is not particularly limited, and examples thereof include a circular plate, an elliptical plate, a triangular plate, and a pentagonal plate.

Examples of the plate-like substrate include a general glass plate such as soda-lime glass, borosilicate glass, aluminosilicate glass, and alkali-free glass, an inorganic glass composed of inorganic materials having various compositions, and a transparent resin plate.

The most preferable material of the glass plate includes glass materials such as soda lime glass, quartz glass, crystal glass, and sapphire glass, and more preferably, high-transmittance glass with a low iron content and a small amount of blue.

The material of the transparent resin plate is preferably a highly transparent resin material, and examples thereof include polyester resins such as polycarbonate and polyethylene terephthalate, polyolefin resins such as polypropylene, polyvinyl chloride, acrylic resins, polyether sulfone, polyarylate, triacetyl cellulose, and polymethyl methacrylate.

The plate-like substrate is most preferably a glass plate in view of its high transparency, light resistance, heat resistance, low refractive index, high planar accuracy, surface scratch resistance, and high mechanical strength.

In order to improve the safety of the glass sheet, the mechanical strength can be improved. In order to improve the mechanical strength of the glass sheet, the glass sheet is subjected to strengthening treatment in advance.

Examples of the strengthening treatment include physical strengthening in which the glass sheet is exposed to high temperature and then air-cooled, or chemical strengthening in which the glass sheet is immersed in a molten salt containing an alkali metal and an alkali metal (ion) having a small atomic diameter present on the outermost surface of the glass sheet is replaced with an alkali metal (ion) having a large atomic diameter present in the molten salt.

In particular, when a thin glass plate is used, it is preferable to use a glass plate that has been chemically strengthened (hereinafter, also referred to as "chemically strengthened glass").

The chemically strengthened glass as the plate-like substrate preferably satisfies the following conditions. That is, the surface compressive stress (hereinafter, referred to as CS) of the glass substrate is preferably 400MPa to 1200MPa, and more preferably 700MPa to 900 MPa. When CS is not less than the lower limit, it is sufficient as a practical strength.

Further, when CS is equal to or less than the upper limit, the material can withstand its own compressive stress, and thus there is no possibility of natural destruction. When the plate-shaped substrate of the present invention is used as a front surface plate (cover glass) of a display device or the like, the CS of the glass substrate is preferably 700MPa to 850 MPa.

The depth of the stress value (hereinafter, referred to as DOL) of the glass substrate is preferably 15 μm to 50 μm, and more preferably 20 μm to 40 μm. If DOL is not less than the lower limit, there is no possibility that DOL is easily damaged and destroyed.

Further, if DOL is not more than the upper limit, the substrate itself can withstand the compressive stress, and there is no possibility of natural destruction. When the plate-shaped substrate of the present invention is used as a front surface plate (cover glass) of a display device or the like, DOL of a glass substrate is preferably 25 μm to 35 μm.

Further, sapphire glass is also preferable in view of mechanical strength.

The shape of the plate-like base is generally a smooth and rectangular shape. The shape of the plate-like base body can be appropriately changed to a desired shape according to the shape of a display panel of the display device, the design of the display device, the mounting position of the display device, and the like.

That is, the shape of the plate-like base is not limited to a smooth shape or a rectangular shape. For example, the glass plate may be a glass plate having an uneven surface, or may have a polygonal shape, a circular shape, or an elliptical shape. Further, the glass may be not only flat glass but also glass having a curved surface shape.

The size of the plate-like base is appropriately determined according to the size of the display panel and the application of the display device. For example, when used as a cover glass for a mobile device, the cover glass preferably has a size of 30mm × 50mm to 300mm × 400mm and a thickness of 0.1mm to 2.5mm, and when used as a display device such as a display device, a car navigation system, a console panel, and an instrument panel, the cover glass preferably has a size of 50mm × 100mm to 2000mm × 1500mm and a thickness of 0.5mm to 4 mm.

The thickness of the plate-like substrate is not particularly limited, and glass having a thickness of 10mm or less can be used. In the case of a glass plate, the thickness is usually about 0.1mm to 6mm from the viewpoint of mechanical strength, transparency, and the like. In particular, when used in an in-vehicle display device, the plate-like substrate is required to be safe, and therefore, from the viewpoint of mechanical strength, the thickness is preferably 0.2mm or more and 2mm or less.

In the case of using chemically strengthened glass, the thickness of the glass substrate is preferably 5mm or less, more preferably 3mm or less, in order to efficiently perform the chemical strengthening treatment. In the case of a transparent resin plate, it is preferably 2mm to 10 mm.

Since light absorption is suppressed to be lower as the thickness is smaller, a glass plate is also preferably used from the viewpoint of improving visibility and transparency. The plate-like substrate is not necessarily limited to a single layer structure composed of a single layer, and may be a multilayer structure composed of a plurality of layers such as laminated glass.

< protective film >

In the manufacturing process and product transportation, in order to protect the display panel assembled in the display device, the 1 st protective film is attached to the plate-shaped base body to protect the plate-shaped base body.

When the display device is used, the 1 st protective film is peeled off from the plate-like base body and used.

One surface of the protective film is provided with a layer having adhesion. The adhesive force may be an adhesive force, a van der waals force, an electrostatic force, or the like, but from the viewpoint of easy peelability for peeling from the plate-like base body and cost, the adhesive force is preferable, and the protective film preferably has an adhesive layer.

By adjusting the adhesion strength of the adhesive forming the 1 st adhesive layer, it is possible to suppress the adhesive from remaining on at least a part of the outermost surface (the 1 st main surface or the anti-reflection layer or the anti-contamination layer or another functional layer) of the plate-shaped substrate, and to suppress peeling of at least a part of the anti-reflection layer or the anti-contamination layer.

In addition, in order to improve the peeling easiness of the protective film, the 1 st protective film can be easily peeled from the 2 nd protective film and the plate-like base body by providing a portion where no adhesive layer is formed on at least a part of the outer peripheral edge of the protective film. Further, the projecting portion formed to facilitate the above-described peelability may be projected from the outer peripheral portion within a range not impairing the operability.

In the case of bonding a plate-shaped substrate provided with an antireflection layer and an anti-contamination layer to a protective film, the bonding may be performed by a manual operation, but from the viewpoint of manufacturing efficiency, a method of bonding a protective film supplied as a roll using a rubber roller or the like, or a method of cutting the protective film into individual films in advance so that the sizes of the protective film and the plate-shaped substrate are matched, and then bonding the films by a label bonding machine or a seal bonding machine is preferable.

< film substrate >

The film substrate is not particularly limited as long as it is a resin sheet-like film substrate. The film substrate may have a single-layer structure or a multilayer structure in which a plurality of layers such as an antistatic layer, a hard coat layer, and an easy-adhesion layer are stacked. In order to prevent forgetting to peel off the protective film from the plate-like substrate, a part or the entire surface of the film-like substrate may be colored or a seal may be attached.

Examples of the film substrate include polyester films such as polyethylene terephthalate, polyethylene films, polyolefin films such as polypropylene, and polyvinyl chloride films. Among them, the polyester film is preferable from the point of adhesion to the adhesive layer, the point of durability and optical characteristics.

The thickness of the film substrate is not particularly limited. The thickness of the film substrate is preferably 5 μm to 100 μm, for example, and more preferably 15 μm to 75 μm, since the film substrate is easily bent and easily peeled off at the time of peeling. If the thickness is less than 5 μm, the plate-like substrate may not be sufficiently protected, and if the thickness exceeds 100 μm, the cost may increase.

< adhesive layer >

The adhesive of the adhesive layer preferably has the following adhesion degree: when the protective film is peeled off from the plate-like base, it is difficult for the adhesive to remain on at least a part of the outermost surface of the plate-like base. The adhesive of the adhesive layer preferably has the following adhesion degree: when the protective film is peeled off from the plate-like substrate, at least a part of the anti-reflection layer and the anti-contamination layer is prevented from being peeled off.

As such an adhesive, acrylic or polyurethane adhesives are preferably used from the viewpoint of adhesiveness and releasability.

When the adhesive strength of the adhesive layer is 0.01N/10mm or more, the adhesive uniformly adheres to the outermost surface of the plate-shaped substrate, and the adhesive layer uniformly adheres to the antireflection layer and the anti-contamination layer. Further, there is no possibility that the function as the protective film is impaired by peeling the protective film from the plate-like base body during transportation.

If the adhesive strength of the adhesive layer is 0.3N/10mm or less, the adhesive strength of the adhesive layer is moderate, and there is no concern that: when the protective film is peeled off, there are problems such as reduction in visibility and contamination due to excessive peeling of at least a part of the anti-reflection layer and the anti-contamination layer and the adhesive remaining on at least a part of the outermost surface of the plate-shaped substrate.

[ examples ] A method for producing a compound

The embodiments of the present invention will be explained. Examples 1 to 5 are examples, and example 6 is a comparative example. The present invention is not limited to the following examples.

[ production of Package ]

[ example 1 ]

As a plate-like substrate, a chemical strengthening glass (non-strengthened DRAGONTRAIL (registered trademark), manufactured by Asahi glass company, described as "DT" in Table 1) having a thickness of 1.3mm and a size of 120mm × 280mm in a plan view was prepared.

As the No. 1 protective film, a type A protective film (model RP-207, manufactured by Ridongton electric Co., Ltd.) comprising a film substrate made of PET having a size of 118mm × 278mm in a plan view and an adhesive layer was prepared.

As the 2 nd protective film, a type a protective film in which the size of the film base in a plan view is 125mm × 285mm was prepared. The static friction coefficient of the protective films against each other was 0.08.

As the contact suppressing member, Miramat (registered trademark) as a highly foamed polyethylene sheet was prepared. The static friction coefficient of the contact suppressing member and the protective film was 0.6.

As the protective plate, a type a protective plate (electrification preventing plastic corrugated plate) formed of plastic and having an octagonal plate shape similar to the above-described embodiment is prepared. The size of the protective plate in plan view is 170mm × 330 mm. The protection shield has a corrugated sheet structure in which lining plates are provided on both sides of the core, and the overall thickness is 3 mm. The flexural modulus of elasticity was 35N/cm.

As the fixing member, a rubber band (rubber band #180, manufactured by yokoku corporation) similar to that of the above embodiment was prepared.

As the storage member, a folded bag made of vinyl (a folded PE bag made of Plus packaging System co., Ltd) was prepared.

First, the 1 st and 2 nd protective films are bonded to the 1 st and 2 nd main surfaces of the plate-like base to prepare a laminate. At this time, the outer edge of the 1 st film base of the 1 st protective film was positioned 1mm inward of the outer edge of the plate base, and the 2 nd protective film was protruded 2.5mm outward of the plate base in the entire outer circumferential direction thereof, and the end regions of both protective films were not closely attached to each other (so that the end faces of the plate base were not protected), thereby producing a laminate. Further, a tab was attached to the 1 st film so as to protrude outward by 1mm from the plate-like base body.

Next, after placing the contact suppressing member on the protective plate, 25 laminated bodies and contact suppressing members were placed in the order of laminated body and contact suppressing member, respectively. Then, a protection plate is placed on the uppermost contact suppressing member. In this case, the centers of the protective plate, the contact suppressing member, and the laminated body are overlapped in a plan view. In addition, the protective plate was protruded to the outside by 25mm with respect to the plate-shaped base body over the entire outer circumferential direction thereof.

Thereafter, the 1 st rubber band (rubber band #180 manufactured by yokoku corporation) was hung around the center of the long side of the protector plate in the short side direction, and the 2 nd rubber band (rubber band #270 manufactured by yokoku corporation) was hung around the center of the short side of the protector plate in the long side direction. At this time, the tension of the 1 st rubber band was 12N, and the tension of the 2 nd rubber band was 11N.

Then, the package body thus produced is stored in the folded bag to produce a package body. In this case, the fold-over pouch is disposed substantially linearly between the outer edges of the upper and lower protective plates when viewed from the side.

[ example 2 ]

As the protective plate, a protective plate of type B (product name of polypropylene triple-foamed sheet manufactured by Mitsui Chemicals tohcell co., Ltd: PAULOWNIA (registered trademark)) was used, the number of rubber bands (rubber band #180 manufactured by koku co., Ltd) was two, and the two rubber bands were hung around the protective plate, the contact suppressing member, and the laminated body so that the longitudinal direction thereof was parallel to the short-side direction of the protective plate and separated by 50 mm. The tension of each elastic band at this time was 12N.

The protective plate of type B is made of polypropylene (PP) triple foamed sheet, and has a dodecagon shape in plan view and a size of 170mm × 330 mm. The flexural modulus of elasticity is 300N/cm. The thickness of the whole of the protective plate was 5 mm.

The package thus produced was stored in a folded bag under the same conditions as in example 1 to produce a package.

[ example 3 ]

As the 1 st protective film of the plate-like base, a type B protective film (model No. RB-100S manufactured by Ridong electrician Co., Ltd.) in which the film base was made of PE was used, and as the protective plate, a type C protective plate made of the same material as type A and having a thickness of 2mm was used. The flexural modulus of elasticity was 12N/cm. As the fixing member, a fastening tape having a tape portion made of polypropylene is used. The static friction coefficient of the protective film and the contact suppressing member was 0.3.

The size of the protective film of type B in the plan view is 154mm × 284 mm.

The protective plate of type C has a rectangular shape having an R portion of 10mm in plan view, and has dimensions of 170mm × 330 mm.

First, 2 fastening tapes were arranged at 50mm intervals, and the same number of protective plates, contact suppressing members, and laminated bodies as in example 1 were placed thereon in the same manner as in example 1. At this time, the center between the 2 fastening tapes was overlapped with the center of the laminate, and the angle formed by the ridge line direction of the center core of the protective plate and the longitudinal direction of the tape portion was 0 °.

Then, both ends of the belt portion are fixed to the upper protective plate by buckles, and the protective plate, the contact suppressing member, and the laminated body are fastened by pulling the end portion of the belt portion on the side where no buckle is provided. At this time, the tension of each fastening tape was set to 20N, and the protective plate, the contact suppressing member, and the protective film were bent along the outer edge of the plate-shaped base body.

[ example 4 ]

As the plate-shaped substrate, DT having a size of 280mm × 140mm in a plan view and uniformly concavely curved with a curvature radius of 1000mm in a short side direction was used. Further, as the 1 st protective film, a type a protective film was used, and the size was 284mm × 144mm in a plan view. Except for this, a package was produced under the same conditions as in example 1. Then, the package was stored in a folded bag under the same conditions as in example 1 to prepare a package.

[ example 5 ]

A package was produced under the same conditions as in example 1 except that the fixing member was 1 rubber band (rubber band #270, manufactured by yokoku corporation) and was hooked around the center of the short side of the protective plate in the longitudinal direction. The tension of the rubber band at this time was 7N. Then, the package was stored in a folded bag under the same conditions as in example 1 to prepare a package.

[ example 6 ]

A packaged body having only 26 contact suppressing members and 25 stacked layers in the same manner as in example 1 was produced without using a protective plate or a fixing member. Then, the package body was stored in the same folded bag as in example 1 to prepare a package body.

[ TABLE 1 ]

[ evaluation ]

[ evaluation of particles ]

The package of example 1 was placed on a trolley and moved on the asphalt floor for 20 minutes. Then, the package was taken out from the folding bag, and the end faces of 25 plate-like substrates were irradiated with green lights, and whether or not particles generated by friction between the folding bag and the protective film were attached to the end faces of the plate-like substrates was confirmed by visual observation. The packages of examples 2 to 6 were also evaluated in the same manner.

As shown in table 1, in the packages of examples 1 to 5 in which the laminate was disposed between the pair of protective plates, no particles were adhered to the end faces of all the plate-shaped substrates (evaluation a), but in the package of example 6 in which the pair of protective plates were not used, there was a plate-shaped substrate in which particles were adhered to the end faces (evaluation C).

The reason for evaluation as A in examples 1 to 5 is considered as follows: since a gap is formed between the folding bag and the protective film by the pair of protective plates, friction between the folding bag and the protective film is suppressed, and no particles are generated. On the other hand, the reason why the evaluation is C in example 6 is considered to be: since there is no pair of protective plates, particles are generated by friction between the folded bag and the protective film, and the generated particles pass between the pair of protective films and reach the plate-like base.

From the above, it can be confirmed that: the stacked body is sandwiched by the pair of protective plates, and the entire outer edges of the pair of protective plates are positioned outside the outer edges of the stacked body, whereby friction between the folded bag and the protective film can be suppressed, and adhesion of particles to the plate-like base body due to the friction can be suppressed.

[ evaluation of vibration resistance ]

The package of example 1 was placed on a cart and moved on the asphalt floor for 20 minutes, and then the package was taken out from the folded bag to confirm the arrangement of the plate-like substrates. As shown in fig. 10, the evaluation of the arrangement state was performed using the offset a between the outer edge of the plate-shaped base 21 whose outer edge is positioned on the center side of the most protective plate 4 and the outer edge of the plate-shaped base 21 positioned on the outer edge side of the most protective plate, and the package with the offset a of 10mm or more was regarded as having no vibration resistance (evaluation C) and the package with the offset a of less than 10mm was regarded as having vibration resistance (evaluation a).

The same evaluation was performed for examples 2 to 6.

As shown in table 1, the package bodies of examples 1 to 4 in which the total tension of the fixing member was not less than 23N were evaluated as a, but the package bodies of example 5 in which the total tension of the fixing member was not more than 7N and example 6 in which the fixing member was not used were evaluated as C.

From this, it is found that, when the total tension of the fixing members is 20N or more, the deviation of the substrate due to the vibration during the conveyance is further reduced.

In addition, the same evaluation as in a showed that the amounts of deviation between examples 1 and 3 were particularly small. In example 3, it is presumed that this is because the tension is sufficiently high. In example 1, it is presumed that this is because the winding is crossed and difficult to move in all of the four directions. Considering the ease of the winding, it is understood that example 1 can most effectively suppress the particles and the substrate from being misaligned.

The present invention has been described in detail with reference to specific embodiments, but it is apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the present invention.

The present application is based on japanese patent application 2018-222190, filed on 28.11.2018, and japanese patent application 2019-152535, filed on 23.8.2019, the contents of which are incorporated herein by reference.
