Glass plate package and glass plate double package

The present invention relates to a glass plate package and a glass plate double package having the glass plate package as a component.

As a packing form for the purpose of transporting and storing glass plates, for example, Patent Document 1 discloses that a glass plate laminate in which a glass plate and a protective sheet are laminated in a flat posture is housed in the inner space of a box. is disclosed.

In addition, in the same document, the upper end and the lower end of the glass plate laminate are configured by a top plate and a bottom plate, respectively, and that the glass plate laminate is loaded and unloaded while the bottom plate is lifted and supported. disclosed to be done.

JP 2012-51586 A

However, as disclosed in Patent Document 1, when a glass plate laminate is housed in a box and transported, slippage occurs between the glass plate and the protective sheet due to vibrations and tilts during transportation, and the glass plate is the main part of the glass plate. The surface may be scratched, or the end face of the glass plate and the box may come into contact with each other and be damaged.

From the above point of view, an object of the present invention is to enable sufficient protection of the glass plates when transporting the glass plate laminate.

(1) The first aspect of the present invention, which was invented to solve the above problems, is to stack a glass plate and a protective sheet in a flat position, and arrange a top plate and a bottom plate on the top and bottom, respectively. It is characterized by obtaining a glass plate package in which the glass plate laminate is bound in the lamination direction by a binding member.

According to such a configuration, the glass plate laminate is bound by the binding member to form the glass plate package, so slippage between the glass plates and the protective sheet is less likely to occur. As a result, it is possible to prevent the main surface of the glass plate from being scratched and the end surface of the glass plate from being damaged.

(2) In the configuration of (1) above, the glass plate, the protective sheet, the top plate, and the bottom plate are rectangular, and the protective sheet is the glass plate, the top plate, and the bottom plate in plan view. and the binding member may be in contact with protruding portions of the protective sheet from the glass plate, the top plate, and the bottom plate.

With this configuration, the protective sheet can be properly fixed by the binding member coming into contact with the protruding portion of the protective sheet. In this case, for example, the binding member can be made to bite into the protruding portion of the protective sheet. Thereby, the glass plate laminate is bound in a stable state.

(3) In the configuration of (1) or (2) above, the binding member is stretched across at least two opposing sides of the top plate, and is stretched across at least two opposing sides of the bottom plate. may have been

By doing so, the binding force of the binding member can be stably applied to the glass plate laminate.

(4) In any one of the configurations (1) to (3) above, the binding member is strung across at least two opposing sides of the top plate at a plurality of locations, and at least two opposing sides of the bottom plate. It may be straddled at a plurality of locations across the edge.

By doing so, it is possible not only to prevent the glass plate from shifting in the direction orthogonal to the two opposing sides, but also to prevent the glass plate from shifting in the direction of rotation. Therefore, the binding force of the binding member can be appropriately applied to the glass plate laminate.

(5) In any one of the configurations (1) to (4) above, the binding member is straddled over one of two opposing sides of the top plate and the other two opposing sides of the top plate, and It may be straddled over one of the two opposing sides of the bottom plate and the other two opposing sides of the bottom plate.

In this way, the binding member is stretched over the upper surface of the top plate and the lower surface of the bottom plate in two directions that intersect each other, so that the binding force of the binding member is more stably applied to the glass plate laminate. be able to.

(6) In any one of the above configurations (1) to (5), the binding member is stretched over one of two opposing sides of the top plate and the other two opposing sides of the top plate at a plurality of locations. At the same time, it may be straddled at a plurality of locations across one of the two opposing sides of the bottom plate and the other two opposing sides of the bottom plate.

By doing so, it is possible not only to prevent the glass plate from shifting in the direction orthogonal to the two opposing sides, but also to prevent the glass plate from shifting in the direction of rotation. Therefore, the binding force of the binding member can be more appropriately applied to the glass plate laminate.

(7) In any one of the above configurations (1) to (6), the length of each of the four sides of the protective sheet, the top plate and the bottom plate is longer than the length of the corresponding four sides of the glass plate. good too.

With this configuration, the protective sheet, the top plate, and the bottom plate can protrude from the four sides of the glass plate in plan view, so that the end face of the glass plate can be protected over the entire circumference.

(8) In any one of the configurations (1) to (7) above, the four sides of the protective sheet are longer than the corresponding four sides of the glass plate, the top plate and the bottom plate. good too.

With this configuration, the protection sheet can protrude from the four sides of the glass plate, the top plate, and the bottom plate in plan view, so that the number of contact points of the binding member with the protection sheet can be increased.

(9) In any one of the configurations (1) to (8) above, the protective sheet may have a protrusion amount of 5 mm or more and 150 mm or less from the end face of the glass plate.

By doing so, the protective sheet protrudes from the end face of the glass plate by an appropriate length, so that the end face of the glass plate can be protected more reliably.

(10) In any one of the above configurations (1) to (9), the binding members may extend from the four sides of the top plate to the corresponding four sides of the bottom plate.

In this way, the binding members stretched over the four portions can be brought into contact with the protruding portions of the protective sheet at the four portions, and the protective sheet can be fixed more securely and stably. can.

(11) In any one of the above configurations (1) to (10), the binding member is a flexible strip-shaped member, and one longitudinal end and the other longitudinal end of the binding member are surface-bonded. It may be formed into an endless shape and wound from the top plate to the bottom plate.

By doing so, the binding member does not have a protrusion such as a knot, so that a large pressing force or the like from the binding member does not locally act on the glass plate laminate. This makes it difficult for the glass plate laminate to deform due to contact with the binding member and damage or breakage of the glass plates resulting therefrom.

(12) In any one of the configurations (1) to (11) above, the binding member may have elasticity.

By doing so, it becomes difficult for the binding member to become loose, and it is possible to suppress the application of an excessive load to the glass plate.

(13) In any one of the configurations (1) to (12) above, the glass plate preferably has a thickness of 0.01 mm or more and 0.3 mm or less and a side dimension of 1000 mm or less. . That is, the glass plate package having any one of the above configurations (1) to (12) is suitable for packaging such thin and small glass plates.

(14) A second aspect of the present invention, which has been devised to solve the above problems, is a glass plate package having any one of the configurations (1) to (13) above, comprising a bottom wall portion and an upper lid. A double package of glass sheets housed in a box having four side walls is obtained.

According to such a configuration, the operation of storing and removing the glass plate laminate from the box body can be performed in the form of the package, so that the workability of the operation of storing and removing can be improved.

(15) In the configuration of (14) above, the upper lid portion may be fitted inside the four side wall portions.

By doing so, even if the height of the glass plate laminate changes, the height position of the lower surface of the upper lid portion can be changed accordingly. Thereby, the gap between the upper surface of the top plate of the glass plate laminate and the lower surface of the upper lid portion can be made as small as possible. In this case, if the thickness of the upper lid portion is varied according to the amount of difference in the height of the glass plate laminate, the upper surface of the upper lid portion and the upper end surface of the side wall portion can be positioned at the same height.

(16) In the configuration of (14) or (15) above, at least two of the four side wall portions facing each other are formed with first notched recesses along the vertical direction on the inner surfaces thereof, and the bottom wall Second notch recesses continuing to the first notch recesses may be respectively formed on the inner surface of the portion.

With this configuration, even if the gap between the inner surface of the side wall portion and the glass plate laminate is small, or if the protective sheet is in contact with the inner surface of the side wall portion, the first notch recess and the second notch are formed. An operator's fingers or other supporting means can be inserted into the recess to easily remove the glass plate laminate from the box. Similarly, the glass plate laminate can be easily accommodated in the box. Moreover, in this way, the gap between the inner surface of the side wall portion and the glass plate laminate can be made as small as possible.

According to the present invention, it is possible to sufficiently protect the glass plates when transporting the glass plate laminate.

It is a partially broken perspective view which shows the whole structure of the modification of the glass plate package which concerns on embodiment of this invention.

A glass plate package and a glass plate double package according to embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a partially cutaway perspective view showing the overall configuration of the glass plate package according to the embodiment of the present invention, and FIG. 2 is an exploded perspective view showing the essential parts of the glass plate package. As shown in these figures, the glass plate package 1 is obtained by binding a glass plate laminate 2 with a binding member 3 . The glass plate laminate 2 is obtained by laminating a plurality of glass plates 4 in a flat posture with a protective sheet 5 interposed between each of them, and placing a top plate 6 and a bottom plate 7 on the upper and lower parts thereof, respectively. . The number of protective sheets 5 interposed between the glass plates 4 may be one or more.

The glass plate 4 is rectangular, and none of the four sides 4a has a thick portion (so-called lug portion) thicker than the central region. The glass plate 4 has a thickness of, for example, 0.01 mm or more and 2 mm or less, preferably 0.02 mm or more and 0.3 mm or less, and a side dimension of 1000 mm or less (the lower limit is, for example, 300 mm). The glass plate 4 is, for example, a panel display such as a liquid crystal display, a plasma display, or an organic EL display, a glass substrate of a device such as a solar cell, a lithium ion battery, a digital signage, a touch panel, or an electronic paper, or a smart phone or a tablet. , mobile devices such as notebook PCs, chemically strengthenable cover glass used for foldable devices, or cover glass used for bendable thin film solar cells and organic EL lighting, etc., medical products It is used for glass containers, window plate glass, laminated lightweight window glass, glass for digital signage, or glass for glass resin laminates used as protective substrates for protective glasses, etc., but is not limited to these uses.

The protective sheet 5 is rectangular and has a thickness of 0.025 to 3 mm. The four sides 5 a of the protective sheet 5 are longer than the corresponding four sides 4 a of the glass plate 4 . Therefore, the protective sheet 5 protrudes from each of the four sides 4a of the glass plate 4 in plan view. The protruding amount of the protective sheet 5 with respect to the four sides 4a of the glass plate 4 is preferably 5 mm or more and 150 mm or less. The lower limit of the protrusion amount is more preferably 10 mm or more, and still more preferably 20 mm or more. The upper limit of the protrusion amount is more preferably 100 mm or less, and still more preferably 50 mm or less. Furthermore, the protective sheet 5 is composed of, for example, interleaving paper (pure pulp paper), resin sheet (eg, polyethylene terephthalate film), or foamed resin sheet. Since the protective sheet 5 is used by being directly laminated on the glass plate 4, the protective sheet 5 is a member with a high degree of cleanliness relative to the glass plate 4, and has a high cushioning property and does not easily scratch the surface. It is preferable to use a member such as a 100% pure pulp interleaving paper or a foamable resin sheet.

Both the top plate 6 and the bottom plate 7 are rectangular. The four

sides

6 a and 7 a of the top plate 6 and the bottom plate 7 are shorter than the corresponding four sides 5 a of the protective sheet 5 . Therefore, the protective sheet 5 protrudes from the four

sides

6a and 7a of the top plate 6 and the bottom plate 7 in plan view. On the other hand, the four

sides

6 a and 7 a of the top plate 6 and the bottom plate 7 are longer than the corresponding four sides 4 a of the glass plate 4 . Therefore, the four

sides

6a and 7a of the top plate 6 and the bottom plate 7 protrude from the corresponding four sides 4a of the glass plate 4 in plan view. Both the top plate 6 and the bottom plate 7 are made of a synthetic resin plate such as foamed polystyrene or foamed polypropylene. The top plate 6 and the bottom plate 7 may be made of plastic cardboard, paper cardboard, or the like. For the top plate 6 and the bottom plate 7, it is preferable to use a resin product with low dust generation in order to maintain the cleanliness of the target glass plate during packaging and transportation. In the present embodiment, both the top plate 6 and the bottom plate 7 have higher rigidity than the protection sheet 5 and are thicker than the protection sheet 5 . Both the top plate 6 and the bottom plate 7 preferably have a bending strength of 1 to 30 MPa and a bending elastic modulus of 100 to 600 MPa. Both the top plate 6 and the bottom plate 7 preferably have moderate cushioning properties.
