Description

  The present invention relates to a plate-shaped storage box.

  Patent Documents 1 and 2 disclose storage boxes for glass plates (plate-like bodies) used in FPDs (Flat Panel Displays) such as liquid crystal displays, plasma displays, and organic EL displays. With these storage boxes, the glass plate is stored in a state where the cleanliness of the main surface of the glass plate is maintained.

  The storage box (substrate transport box, plate-shaped body storage case) of Patent Documents 1 and 2 includes a bottomed main body. Grooves into which the peripheral edge of the glass plate is inserted are formed in a pair of opposed inner wall surfaces of the main body. Moreover, the groove | channel where the peripheral part of a glass plate is inserted is formed also in the inner bottom face of the bottom body part of a main-body part.

  As in Patent Documents 1 and 2, the groove provided on the inner bottom surface of the main body of the storage box is not formed on the entire inner bottom surface, and is a central portion between the pair of inner wall surfaces, It is formed on the surface of about 60% to 70% of the surface area.

  The storage box disclosed in Patent Document 2 targets a glass plate having a thickness of 0.3 mm to 0.5 mm. Patent Document 2 discloses that the groove interval is 10 mm to 15 mm.

JP 2002-347882 A JP 2011-11790 A

  However, when a glass plate having a thickness of 0.5 mm or less is stored in the storage box of the cited documents 1 and 2, the glass plate is bent by its own weight because the thickness is thin, and the adjacent glass plates are in contact with each other. There was a case where it was damaged.

  In addition, as described above, a glass plate having a thickness of 0.5 mm or less has a greater amount of bending due to its own weight than a glass plate having a thickness of more than 0.5 mm. In some cases, the peripheral edge of the glass plate may be removed from the groove.

  That is, the storage boxes of Patent Documents 1 and 2 have the above-mentioned problems because the holding force is weak against a thin glass plate.

  This invention is made | formed in view of such a situation, and it aims at providing the storage box of a plate-shaped object which can raise the retention strength with respect to the stored plate-shaped object.

  In one embodiment of the present invention, in order to achieve the above object, a pair of inner wall surfaces having a box-shaped main body portion provided with an opening portion on one side and a bottom portion on the other side are provided. A plurality of first grooves into which the peripheral edge of the plate-like body is inserted are provided at a predetermined interval, and a plurality of second grooves into which the peripheral edge of the plate-like body is inserted are provided on the inner bottom surface of the bottom. The bottom portion includes a main bottom portion integral with the main body portion, and a sub-bottom portion detachably attached to an opening excluding the main bottom portion, and an inner bottom surface of the main bottom portion and the Provided is a plate-shaped storage box in which the second groove is provided on the inner bottom surface of the sub-bottom part.

  According to one aspect of the present invention, the bottom portion of the main body portion is configured by the main bottom portion that is integral with the main body portion, and the sub-bottom portion that is detachably attached to the opening excluding the main bottom portion. A second groove is provided on each inner bottom surface of the bottom. That is, in comparison with the storage box of Patent Documents 1 and 2 having the second groove only on the main bottom, the holding force for the plate-like body stored in the storage box is compared with the storage box of Patent Documents 1 and 2. And enhanced.

  When the plate-like body is housed in the main body portion from the opening of the main body portion, the vertical edge portions on both sides of the plate-like body are inserted into the first grooves formed in the pair of inner wall surfaces, And it is accommodated in the inside of the main body while being guided by the first groove. Then, the lower edge of the plate-like body is inserted into the second groove. As a result, the plate-like body is stably stored in the main body. Therefore, even if the plate-like body is a thin plate-like body that is easily bent due to its own weight and is thin, the plate-like body is stored in the storage box in a state in which the deflection is particularly restricted by the second groove. Note that after the prescribed number of plate-like bodies are stored in the storage box, the opening of the main body is closed by the lid.

  Further, according to one aspect of the present invention, when a thin plate (thickness of 0.5 mm or less) that is easy to be bent due to its own weight is stored in the storage box, the plate is stably provided. For storage, the sub-bottom is attached to the opening in the bottom. On the other hand, in the case of a plate-like body that is difficult to be bent by its own weight and is thick (thickness is more than 0.5 mm), the sub-bottom part is unnecessary, so the sub-bottom part is removed from the bottom part, and the second main bottom part is removed. The lower edge of the plate-like body is inserted only into the groove.

  By configuring the sub-bottom part so as to be detachable as described above, plate-like bodies of various thicknesses can be stored in one storage box. That is, since the storage box of one embodiment of the present invention is versatile, it is possible to obtain an effect that it is not necessary to prepare storage boxes in a form corresponding to the thickness of the plate-like body.

  Even if it is a plate-like body having a thickness of more than 0.5 mm, the lower edge portion may be inserted into the second groove of the main bottom portion and the sub-bottom portion in the same manner as the plate-like body having a thickness of 0.5 mm or less. Good. However, in this case, since the entire edge of the lower edge of the plate-like body having a thickness of more than 0.5 mm is inserted and fitted into the second groove, the plate-like body by the second groove The holding force of the lower edge of the is excessive. Therefore, when taking out the plate-like body having a thickness of more than 0.5 mm from the storage box, that is, when pulling out the lower edge portion of the plate-like body having a thickness of more than 0.5 mm from the second groove, Since force is required, a plate-like body having a thickness exceeding 0.5 mm may be damaged. In one embodiment of the present invention, such a problem can be prevented.

  In one aspect of the present invention, the main bottom portion is disposed at a central portion between the pair of inner wall surfaces provided with the first groove, and the sub-bottom portion is at both end portions between the pair of inner wall surfaces. It is preferable to arrange | position.

  According to one aspect of the present invention, the portion near the end of the lower edge portion of the glass plate is inserted into the second groove of the pair of sub-bottom portions arranged on both sides of the main bottom portion. The holding force with respect to the plate-shaped body made is enhanced as compared with the storage boxes of Patent Documents 1 and 2.

  In one aspect of the present invention, in the form in which the sub-bottom part is attached to the opening of the bottom part, the main bottom part and the sub-bottom part are in close contact, and the second groove of the main bottom part and the sub-bottom part are It is preferable that the second groove communicates with the second groove.

  According to one aspect of the present invention, since the second groove of the main bottom and the second groove of the sub-bottom are communicated with each other, compared to a mode in which there is a gap between the main bottom and the sub-bottom, It is possible to prevent the glass plate from being bent in the gap. Therefore, the holding force with respect to the plate-shaped body accommodated in the storage box is enhanced as compared with the embodiment having the gap.

  In one aspect of the present invention, the entire inner bottom surface of the bottom portion is configured by the inner bottom surface of the main bottom portion and the inner bottom surface of the sub-bottom portion, and the second groove is provided over the entire inner bottom surface of the bottom portion. It is preferable.

  According to the aspect of the present invention, since the second groove is provided in the entire inner bottom surface of the bottom portion, the holding force for the plate-like body stored in the storage box is further enhanced.

  In one aspect of the present invention, the hardness of the sub-bottom portion is preferably lower than the hardness of the main body portion and the main bottom portion.

  According to one aspect of the present invention, the rigidity of the storage box is obtained by the main body portion and the main bottom portion that are manufactured by a hard member having high hardness, so that the plate-like body can be protected from impact during transportation. Moreover, since the sub-bottom part manufactured with the soft member with low hardness absorbs the vibration at the time of transportation, it can protect a plate-shaped object from a vibration.

  In one embodiment of the present invention, the plate-like body is preferably a glass plate having a thickness of 0.5 mm or less.

  According to one aspect of the present invention, it is effective in storing a glass plate having a thickness of 0.5 mm or less that is easily bent by its own weight, and further effective in storing a glass plate having a thickness of 0.3 mm. To do.

  As described above, according to the plate-shaped body storage box of the present invention, it is possible to increase the holding force for the stored plate-shaped body.

  A preferred embodiment of a storage box for a plate-like body according to the present invention will be described below with reference to the accompanying drawings.

  In the following embodiments, a glass plate is exemplified as the plate-like body, but the plate-like body is not limited to the glass plate, and the plate-like body of the present invention may be a plate-like body having a thin thickness made of resin or metal. Body storage box can be applied.

  FIG. 1 is a perspective view illustrating a storage box 10 and a plurality of glass plates 12 according to the embodiment. FIG. 2 is a perspective view showing the main body 14 of the storage box 10 shown in FIG. FIG. 3 is a longitudinal sectional view of the storage box 10.

  The storage box 10 includes a main body portion 14, a lid 16, and a pair of support cushions (sub-bottom portions) 18 and 18. In this storage box 10, a plurality of glass plates 12 each having a rectangular size of 300 mm to 1000 mm and a thickness of 0.3 mm to 0.5 mm are stored.

  The main body portion 14 is configured in a horizontally long box shape as shown in FIGS. 1 and 2, and is provided with an opening 20 for inserting and removing the glass plate 12 at the top, and a rectangular bottom at a position facing the opening 20. 22 is provided. In addition, although the main-body part 14 of embodiment is a horizontally long box-shaped body, it is not limited to this, A vertically long box-shaped body may be sufficient.

  In addition, a plurality of grooves 26 (first grooves) into which the vertical edge portions 12 </ b> A and 12 </ b> A on both sides of the glass plate 12 are inserted in the pair of inner wall surfaces 24 and 24 that face the main body 14. It is formed with a predetermined interval in the width direction. Further, in FIG. 2, a plurality of grooves 28 (second grooves) into which the entire edge portion of the lower edge portion 12B of the glass plate 12 is inserted are formed on the entire inner bottom surface 22A of the bottom portion 22 with the predetermined interval. The In addition, since another pair of inner wall surfaces 25 and 25 which the main-body part 14 opposes are the inner wall surfaces which oppose the surface of the glass plate 12, a groove | channel is not formed but it is a flat surface.

  The cross-sectional shape and depth of the grooves 26 and 28 are the shape and depth that can hold the vertical edge portion 12A and the lower edge portion 12B of the glass plate 12 inserted into the grooves 26 and 28 as shown in the cross-sectional view of FIG. Is set to Moreover, the space | interval of the groove | channels 26 and 28 is set to the space | interval which the adjacent glass plates 12 inserted and hold | maintained at the grooves 26 and 28 do not contact. As an example, the cross-sectional shape of the groove 26 is substantially V-shaped, its depth is about 12 mm, and the interval is about 10 mm. Further, the cross-sectional shape of the groove 28 is also substantially V-shaped, its depth is about 7 mm, and the interval is about 10 mm.

  Next, a method for storing the glass plate 12 in the storage box 10 will be described.

  The glass plate 12 is housed in the main body portion 14 through the opening 20 of the main body portion 14 with the lower edge portion 12B of the glass plate 12 at the top.

  At this time, the vertical edge portions 12 </ b> A and 12 </ b> A on both sides of the glass plate 12 are inserted into the grooves 26 and 26 and are housed in the main body portion 14 while being guided by the grooves 26 and 26. Then, the entire edge portion of the lower edge portion 12B of the glass plate 12 is inserted into a groove 28 formed on the entire inner bottom surface 22A of the bottom portion 22 as shown in FIG. Thereby, the glass plate 12 is stably accommodated in the main body 14.

  Therefore, even if the glass plate 12 is a thin glass plate 12 that is easy to bend due to its own weight and has a small thickness (thickness of 0.5 mm or less), the glass plate 12 is stored in a state in which the bending is restricted by the groove 28. 10 is stored. After the prescribed number of glass plates 12 are stored in the storage box 10, the opening 20 of the main body 14 is closed by the lid 16.

  As described above, the storage box 10 according to the embodiment includes the groove 28 into which the entire edge portion of the lower edge portion 12B of the glass plate 12 is inserted on the entire inner bottom surface 22A of the bottom portion 22 of the main body portion 14. Therefore, according to the storage box 10 of the embodiment, the holding force for the glass plate 12 stored in the storage box 10 is higher than that of the storage box disclosed in Patent Documents 1 and 2.

  According to the storage box 10 of the embodiment, the glass plate 12 is bent by its own weight and the adjacent glass plates 12 come into contact with each other, or the vertical edge portion 12A and the lower edge portion of the glass plate 12 are caused by vibration during transportation of the storage box 10. The problem that 12B is detached from the grooves 26 and 28 can be solved.

  On the other hand, the bottom portion 22 of the storage box 10 of the embodiment is constituted by a rectangular main bottom portion 30 and a pair of rectangular support cushions 18 and 18. The main bottom portion 30 is located at the center of the bottom portion 22 and is formed integrally with the main body portion 14. The pair of support cushions 18 and 18 are detachably attached to the rectangular openings 32 and 32 formed on both sides of the main bottom portion 30 by fitting.

  That is, the main bottom portion 30 is disposed at the center portion between the pair of inner wall surfaces 24, 24 provided with the groove 26, and the support cushions 18, 18 are disposed at both end portions between the pair of inner wall surfaces 24, 24. Has been.

  According to the main body part 14 in which the bottom part 22 is separated and constituted by the main bottom part 30 and a pair of detachable support cushions 18, 18, a thin glass plate 12 (thickness of 0.5 mm or less) that is easily bent by its own weight. ) Is stored in the storage box 10, the support cushions 18 and 18 are attached to the openings 32 and 32 of the bottom portion 22 in order to stably store the glass plate 12. On the other hand, in the case of a glass plate having a thickness exceeding 0.5 mm (thickness exceeding 0.5 mm), which is difficult to be bent by its own weight, the support cushions 18 and 18 are unnecessary, so the support cushions 18 and 18 are attached to the bottom 22. And the lower edge of the glass plate is inserted only into the groove 28 of the main bottom 30.

  Even if the glass plate has a thickness of more than 0.5 mm, the lower edge is inserted into the main bottom 30 and the grooves 28 of the support cushions 18 and 18 in the same manner as the glass plate 12 having a thickness of 0.5 mm or less. Also good. However, in this case, since the entire edge of the lower edge of the glass plate having a thickness of more than 0.5 mm is inserted into and fitted into the groove 28, the lower edge of the glass plate is held by the groove 28. Power is excessive. Therefore, when taking out the glass plate having a thickness of more than 0.5 mm from the storage box 10, that is, when pulling out the lower edge portion of the glass plate having a thickness of more than 0.5 mm from the second groove, an excessive force is required. Therefore, there is a case where a glass plate having a thickness of more than 0.5 mm is damaged. Therefore, when storing a glass plate having a thickness of more than 0.5 mm, it is preferable to remove the support cushions 18 and 18 from the bottom 22.

  Further, the support cushions 18 and 18 are made of a soft member with respect to the main body portion 14 and the main bottom portion 30.

  That is, since the rigidity of the storage box 10 is obtained by the main body portion 14 and the main bottom portion 30 which are manufactured by a hard member having high hardness, the glass plate 12 can be protected from an impact during transportation. Moreover, since the support cushions 18 and 18 manufactured with the soft member with low hardness absorb the vibration at the time of transport, the glass plate 12 can be protected from a vibration. As an example, the main body 14 and the main bottom 30 are preferably made of polypropylene, and the support cushions 18 and 18 are preferably made of polyethylene.

  As described above, the storage box 10 of the embodiment is effective for storing the glass plate 12 having a thickness of 0.5 mm or less. The effect is further exhibited in storing a glass plate having a thickness of 0.3 mm.

  The storage box 10 of the embodiment has a configuration in which the main bottom portion 30 and the support cushions 18 and 18 are in close contact with each other as shown in FIG. 2 in the form in which the support cushions 18 and 18 are attached to the opening 32 of the bottom portion 22. The groove 28 of the main bottom portion 30 and the grooves 28 of the support cushions 18 and 18 are communicated with each other. Then, the groove 28 is provided on the entire inner bottom surface 22A of the bottom portion 22. However, the present invention is not limited to the above form.

  For example, the main bottom portion 30 and the support cushions 18 and 18 may not be in close contact with each other, and there may be a gap between the main bottom portion and the support cushions 18 and 18. That is, even if the groove 28 is not provided in the entire inner bottom surface 22A of the bottom portion 22, as long as the support cushions 18 and 18 are provided, the holding force of the glass plate 12 can be increased.

  1 is formed with a plurality of grooves 36 into which the vertical edge portions 12A and 12A of the glass plate 12 are inserted. The lid 16 is not limited to the form shown in FIG. 1, and may take any form as long as it can close the opening 20 of the main body 14.
