Description

  The present invention relates to a plate-like container for transporting and storing various glass substrates such as glass plates for glass, liquid crystal displays and plasma displays, and other plate-like bodies. .

  Conventionally, it is made of synthetic resin foam with buffering properties as a transport container for storing and transporting relatively large glass substrates such as base glass and liquid crystal display glass substrates and other impact-resistant plate-like bodies. In this case, the plate-like bodies are inserted one by one into the longitudinal grooves arranged at equal intervals on the inner surface of one opposite side wall of the container body so as not to contact each other. As described above, a device that is supported and stored in an upright state is generally used.

  In recent years, due to an increase in demand for large-sized liquid crystal televisions and plasma televisions, large-sized glass substrates in which one or both of the vertical and horizontal directions exceed 100 cm have been adopted as glass substrates for televisions. Transport containers for transport are also becoming larger.

  However, in the conventional method of accommodating the glass substrate upright by the vertical grooves on the inner surface of the side wall, the glass substrate itself is bent and deformed by its own weight due to the large and heavy glass substrate, or the weight of the glass substrate is increased. When the load is concentrated on the bottom of the container body, the bottom of the container is compressed and deformed, and the cushion function and the impact relaxation function may be impaired.

  In order not to cause such a problem, as exemplified in Patent Document 1, glass substrates and protective sheets are alternately stacked and stored in the container body, and each glass substrate is placed through the protective sheet. A container for transport that has been received at has also appeared.

  Usually, in order to improve the efficiency in transportation, it is common to pack a plurality of containers containing plate-like bodies in a stacked state and use them for transportation. At the time of stacking, it is required that each container can be held with good stability without causing a shift. Therefore, in Patent Document 1, the upper surface of the lid body and the container that become the stacking surface at the time of stacking are required. Concave portions (concave grooves) are formed on one side of the bottom surface of the main body, and convex portions (convex ridges) are formed on the other side, and the concave portions and the convex portions are placed in a fitted state and stacked.

  In the case of the fitting structure between the concave portion and the convex portion, the fitting structure is inwardly of the upper surface of the lid body serving as a stacking surface and the bottom lower surface of the container body, and the air in the concave portion is unlikely to escape. In addition, it is difficult to fit in the stacking operation, and when the containers stacked in the fitted state are separated into individual containers, a lower container lid is attached to the bottom lower surface of the upper container. May come off.

  Further, if the concave portion and the convex portion of the fitting structure are inward of the stacking surface and cannot be seen from the outside, the upper container is stacked in a normal position at the time of stacking, and the concave portion and It is not easy to confirm from the outside of the stacked state whether or not the protrusions are properly fitted. If misalignment occurs during stacking, the stacking state may become unstable, and there may be a collapse of the load during transportation. The deformation is likely to occur, and the effect of preventing deviation cannot be obtained due to this.

  Therefore, when the container is displaced in the above-described stacking, it is necessary to reload the container to a normal position, and it is desired that the stacked state can be easily confirmed. Then, such consideration is not made.

  Further, when the containers are stacked and used for transportation, if the load of the upper container due to the stacking, that is, the stacking load is applied to the entire top plate portion of the lid of the lower container, the stored plate-like body is There is a possibility that the plate-like body may be cracked or broken due to the stacked load.

JP 2008-239210 A

  The present invention has been made to solve the above-described problems, and is a plate-like body for storing and transporting a plate-like body such as a glass substrate or a solar battery panel in a state of being stacked via a protective sheet. As a transport container, it can be easily fitted and separated from the stacked state, and it is easy to check the stacked state so that a normal stacked state can be easily obtained and stored. It is an object of the present invention to provide a transport container that can be stacked without applying a stacking load to the plate-like body.

The present invention that solves the above problems comprises a flat rectangular container body that opens upward, and a lid that is attached to the opening of the container body, and stores a plurality of plate-like bodies in a stacked state. A container for transporting in a stackable manner, and a support wall portion for receiving and supporting a peripheral edge of a bottom bottom surface of the upper container body at the time of stacking is provided on the upper peripheral edge portion of the lid body. The bottom surface of the bottom is provided with a fitting convex portion that fits inside the support wall portion in an inner region excluding a peripheral edge portion that is received and supported by the support wall portion of the lower lid when stacked. Provided in a mated state so that they can be stacked, a part of the support wall is provided with a notch that communicates from the inner part to the outside, and the protrusion height of the fitting convex part on the bottom lower surface of the container body Is lower than the protruding height of the support wall .

According to the above-mentioned transport container, when stacking the plate body in a state where the plate body is accommodated in the container body and the lid body is attached, the fitting convex portion provided on the bottom lower surface of the upper container body is provided with the lower lid. It fits inside the support wall part which has in the upper surface peripheral part of a body. In particular, at this time, it is possible to easily fit the air while letting the internal air escape from the notch part of the support wall part. Further, when separating the stacked containers, the air flows into the inside of the support wall from the notch, so that the fitting convex portion can be easily detached from the inside of the support wall, and the bottom of the bottom of the container body is With the lid of it will not come off. Moreover, in the stacked state, since the peripheral edge portion of the bottom surface of the bottom of the upper container body can be received by the support wall portion, a large stacked load acts on the center portion (top plate portion) of the lid. Therefore, it is possible to prevent a load from being applied to the housed plate-like body via the top plate portion.
In addition, since the protruding height of the fitting convex portion on the bottom surface of the bottom of the container body is lower than the protruding height of the support wall portion, the stacking load can be received by the peripheral edge support wall portion of the lid body. No stacking load acts on the top plate. Therefore, the stored plate-like body does not receive a stacking load.

  Furthermore, it is preferable that the fitting convex part is provided with a notch groove that leads to the notch part during stacking, so that the position of the side wall of the notch groove in the notch part that opens to the side surface in the stacked state. By confirming the above, it is possible to easily confirm whether or not the stacked upper and lower containers are displaced.

  In the transport container for the plate-like body, the fitting convex portion is provided along the peripheral edge portion leaving a non-projecting portion at a central portion, and on the upper surface of the lid body, the non-projecting portion is provided. The convex part to fit can be provided. As a result, the fitting state is stable by fitting inside the support wall part of the lid of the lower part of the fitting convex part on the bottom bottom surface of the upper container body and fitting outside the convex part of the center part. The positioning effect is enhanced. In this case, it is preferable that the protruding height of the convex portion on the upper surface of the lid body is lower than the protruding height of the support wall portion. Thereby, a stacked load can be received by the support wall part of the peripheral part of a cover body, and a stacked load does not act on a top plate part.

  In the plate-shaped container for transporting the plate-like body, the notch portion is provided opposite to the support wall portion on at least one opposite side of the upper surface of the lid body, and fits inside the support wall portion during stacking. The fitting convex part on the bottom surface of the bottom part is formed with a notch groove that linearly communicates the two notch parts when stacked, and the side wall of the notch groove is positioned within the width of the notch part. Is preferred. In practice, it is particularly preferable that the side wall of the notch groove is formed so as to be positioned at the center within the width of the notch portion so that misalignment can be easily confirmed.

  Thereby, in the state of stacking as described above, by checking the position of the side wall of the notch groove by looking through the notch portion that opens to the side surface, whether or not the stacked containers are misaligned, Whether or not the fitting convex portion is normally fitted to the support wall portion can be more easily confirmed.

  In the plate-like container for transportation, two notch portions are respectively provided in the supporting wall portions on one opposite side, and the fitting convex portion on the bottom bottom surface that fits inside the supporting wall portion at the time of stacking. And a notch groove that linearly communicates both notches on both sides of the opposite side, and the fitting convex part is fitted between the two notches to the inside of the support wall part on one opposite side. It is divided into a fitting convex part and a second fitting convex part that fits inside the supporting wall part on the other opposite side, and the first fitting convex part comes into contact with the supporting wall part on the opposing both sides A flat H shape having a transition portion between both end portions may be formed, and convex portions on the upper surface of the lid body may be provided so as to be fitted to non-projecting portions on both sides of the transition portion.

  Thereby, the fitting convex part of the bottom lower surface of the container body is fitted to the supporting wall part of the upper surface of the lid body and the convex part of the central part, so that the effect of regulating the positional deviation in both the front, rear, left and right directions is great. It is possible to maintain a stable stacked state.

  As described above, according to the container for transporting a plate-like body of the present invention, the fitting and stacking state when the plate-like body such as a glass substrate is stored and stacked in a stacked state via a protective sheet. Separation operation is easy, and it is easy to check the stacking state, so that a normal stacking state can be easily obtained, and positional displacement and disengagement may occur due to vibration during transportation. And can maintain a stable stacked state. In addition, by receiving the stacking load at the support wall at the peripheral edge of the lid, it can be stacked and transported without applying the stacking load to the stored plate-like body, and the plate-like body is well protected. obtain.

  Next, embodiments of the present invention will be described based on examples shown in the drawings.

  FIGS. 1-10 has shown the 1st Example of the container for conveyance of the plate-shaped object concerning this invention. As shown in FIG. 1, the transport container A of this embodiment opens upward, and a plate-like body B such as a glass substrate to be stored is interposed between the plate-like bodies via a protective sheet C for spacers. It consists of a flat rectangular container body 1 that can be stored in a stacked state, and a lid 3 that is attached to the opening of the container body 1.

  The container body 1 is mainly formed of a synthetic resin foam having a buffering property, and a storage space is formed by the four side walls 12a, 12b, 12c, and 12d that rise from the bottom 11. The storage space is formed to a depth that allows the required number of plate-like bodies B stacked via the protective sheet C to be stored. Usually, although it changes also with the thickness of the plate-shaped body B, in the case of the plate-shaped body B, such as a glass substrate of thickness 2-5 mm, for example, it forms relatively shallowly so that about 10 to several dozen sheets can be accommodated.

  In the case of the figure, the side wall inner surface of the container body 1 is provided with cutouts 13 at the four corners so that the corners of the plate-like body B to be stored do not directly contact the side wall inner surface. A notch 14 for inserting a locking member at the time of storing and taking out operation is provided at the central portion in the length direction of the side of the inner surface of the side wall. A contact member made of a material having elasticity can be provided on the inner surfaces of the side walls 12a, 12b, 12c, and 12d as necessary. Moreover, although not shown in figure, the upper surface of the bottom part 11 of the said container main body 1 can also be made into the uneven surface divided by forming the groove in at least one direction of width and width as needed.

  The lid 3 is formed of a synthetic resin foam having a cushioning property similar to that of the container main body 1, and is provided so as to be fitted and attached to the opening of the container main body 1. As means for attaching the lid 3 to the opening of the container body 1, the opening of the container body 1 is formed with a notch step 16 on the outside leaving a convex edge 15, and the lid 3 is formed so that the fitting portion 32 projecting from the lower surface side peripheral edge portion 3 fits to the outside of the convex edge 15 to a position where it abuts on the notch step portion 16.

  In the case of the figure, the lower surface of the peripheral portion of the top plate portion 31 of the lid 3, that is, the portion that contacts the upper end surface of the convex edge 15 along the fitting portion 32 is slightly recessed, In the wearing state, the recessed portion 33 is in contact with the upper end surface of the convex edge 15, and the inner lower surface 31 a of the top plate portion 31 is formed to enter slightly below the upper end position of the convex edge 15. Thus, the stored plate-like body B can be pressed and held below the upper end position of the convex edge 15.

  Then, as a structure for stacking the transport containers A in a state where the lid body 3 is attached, a peripheral portion of the upper surface 3a of the lid body 3 is continuously provided on the side surfaces of the four sides. Support wall portions 34a, 34b, 34c, and 34d that support the peripheral edge of the lower surface of the bottom of the upper container body 1 when stacked are provided so as to protrude from the upper surface 3a. The support wall portions 34a, 34b, 34c, and 34d have a width corresponding to the thickness of each of the side walls 12a, 12b, 12c, and 12d of the container body 1, and the stacked load is applied to the support wall portions 34a, 34b, 34c, It is formed so as to be supported by 34d and not to apply a stacking load to the top plate portion 31.

  A part of the support wall portions 34a, 34b, 34c, 34d, for example, a part of one opposite side, preferably the support wall portions 34a, 34c on the opposite sides on the long side as shown in the figure for ventilation. The notch 35 is provided so that the air inside the support walls 34a, 34b, 34c, 34d can be released during the fitting operation, and the air is supported when the fitting is released. It can flow inward of the walls 34a, 34b, 34c, 34d. The notch 35 can be provided at one or a plurality of arbitrary locations such as a central portion in the length direction of the sides of the support wall portions 34a, 34b, 34c, 34d. For example, in the example shown in the figure, two notch portions 35 are provided opposite to each other on the support wall portions 34a and 34c on one opposite side with an interval in the length direction of each side.

  On the other hand, on the lower surface 11a of the bottom portion 11 of the container body 1, an inner region excluding the peripheral edge portion 17 supported by the support wall portions 34a, 34b, 34c, 34d of the lid body 3 of the lower container when stacked. Further, a fitting convex portion 18 is provided to fit inside the support wall portions 34a, 34b, 34c, 34d when stacked, and the fitting convex portion 18 and the support wall portions 34a, 34b, 34c, 34d are provided. It can be positioned by fitting with. As will be described later, the fitting convex portion 18 is formed with a notch groove 20 that leads to the notch groove 35 in a state of being fitted to the support wall portions 34a, 34b, 34c, and 34d. From 35, the position of the notch groove 20 can be easily confirmed.

  The fitting convex portion 18 has a shape corresponding to the entire inner region of the support wall portions 34a, 34b, 34c, 34d (not shown). It can be provided along the peripheral edge portion 17 leaving a concave non-projecting portion 19 by the lower surface 11a. In this case, the upper surface 3a of the lid 3 is provided with a convex portion 36 that fits to the non-projecting portion 19 inside the fitting convex portion 18, and the convex portion 36 is moved to the non-projecting portion during stacking. It is preferable to have a structure to be fitted to 19, so that the positioning effect, fitting strength and stability during stacking can be further enhanced. It is also possible to omit the convex portion 36.

  The fitting convex portion 18 is formed so that the protruding height h1 from the bottom lower surface 11a is lower than the protruding height h2 from the lid upper surface 3a of the support wall portions 34a, 34b, 34c, and 34d. It is preferable for preventing the stacking load from being applied to the top plate portion 31 of the lid 3. Further, as described above, when the projection upper surface 3a is provided with the convex portion 36 fitted to the non-protruding portion 19, the projection height h3 of the convex portion 36 is set so that the support wall portions 34a, 34b, It is preferable to set the projection height h2 lower than 34c and 34d so as not to apply a stacking load to the top plate portion 31 of the lid 3. More preferably, the protrusion height h3 of the protrusion 36 is set lower than the protrusion height h1 of the fitting protrusion 18.

  The cutout groove 20 formed in the fitting convex portion 18 can be implemented in various forms leading to the cutout portion 35. As described above, the support wall portion 34a on the long side of one of the opposite sides is provided. When notches 35 are provided opposite to each other on 34c, as shown in the figure, the fitting protrusions 18 that fit inside the support wall portions 34a, 34c have both the opposite sides when stacked. A notch groove 20 is formed which communicates the notches 35 and 35 in a straight line. In particular, when two cutout portions 35 are provided at intervals in the support wall portions 34a and 34c, the fitting convex portion 18 has both cutout portions 35 and 35 that are opposed to each other when stacked. Two notch grooves 20 to be communicated are formed, so that the fitting convex portion 18 is fitted between the two notch portions 35 and 35 inside the support wall portions 34a and 34c on one opposite sides, respectively. First fitting projections 18-1 and 18-1 and second fitting projections 18-2 and 18-2 fitted inside the supporting wall portions 34b and 34d on the other opposite sides. The first fitting convex portions 18-1 and 18-1 are divided and formed as non-projecting portions 19.

  In any case, the side wall 21 of the notch groove 20 is formed so as to be located at a predetermined position within the width of the notch 35, and the position of the side wall 21 is confirmed through the notch 35 in the stacked state. It can be done. In the case of the figure, the notch groove 20 is such that the side wall 21 by the edge of the first fitting convex portion 18-1 is positioned at a predetermined position within the width of the notch portion 35, for example, at the center during normal stacking. By confirming the position of the side wall 21 within the width of the notch portion 35, it is possible to confirm the presence or absence of positional deviation.

  The upper surface 3a of the lid 3 has an edge of a convex portion 36 that fits into the non-projecting portion 19 between the first fitting convex portions 18-1 and 18-1 of the fitting convex portion 18. The first fitting projections 18-1 and 18-1 are formed so as to form a part of the side wall 21 of the notch groove 20 continuously from the edge. The convex portion 36 may be formed integrally with the first fitting portion 18-1 on the bottom lower surface 11 a of the container body 1.

  According to the container A for transporting a plate-like body of the first embodiment, when the plate-like body B such as a glass plate for glass or a liquid crystal display is stored, first, a spacer is placed on the bottom 11 of the container body 1. The protective sheet C for use is placed, and the plate-like body B and the protective sheet C are alternately stacked and stored thereon. As the protective sheet C, a flexible soft synthetic resin foam sheet, for example, a polyolefin resin foam sheet, is preferably used. The thickness of the foamed sheet varies depending on the thickness and type of the plate-like body B to be accommodated, but usually a thickness of 0.2 to 5.0 mm is preferably used.

  In the state where the plate-like body B and the protective sheet C are alternately stacked and stored and the lid body 3 is fitted and attached to the container body 1 as described above, a plurality of transport containers A are stacked and transported. Provide. At this time, the fitting protrusion 18 provided on the bottom lower surface 11a of the upper container body 1 is fitted inside the support wall portions 34a, 34b, 34c, 34d provided on the upper surface of the lower cover body 3, thereby providing a position. It is possible to stack with good stability without deviation. In particular, during the stacking, it is possible to easily fit the air while letting the internal air escape from the notch 35 provided in a part of the support walls 34a, 34b, 34c, 34d. Further, when separating the stacked containers, air flows into the support wall portions 34a, 34b, 34c, 34d from the cutout portion 35, so that the fitting convex portion 18 becomes the support wall portions 34a, 34b. 34c, 34d can be easily detached from the inside of the container body 1, and the bottom lower surface 11a of the container body 1 is not attached to the lower lid 3 and detached.

  Moreover, in the stacked state, the support wall portions 34 a, 34 b, 34 c, 34 d can receive the peripheral edge portion 17 of the bottom lower surface 11 a of the upper container body 1, and the top plate portion 31 of the lid body 3 can be received. It is possible to prevent a large stacked load from acting. In particular, the protrusion height h1 of the fitting convex portion 18 and the protrusion height h3 of the convex portion 36 on the bottom lower surface 11a of the container body 1 are lower than the protrusion height h2 of the support wall portions 34a, 34b, 34c, 34d. In this case, the stacked load can be received by the support wall portions 34 a, 34 b, 34 c, 34 d at the peripheral edge of the lid 3, and a large stacked load does not act on the top plate portion 31 of the lid 3. Therefore, the stored plate-like body B is not subjected to a stacking load, and the protection can be satisfactorily achieved.

  That is, when a large stacking load is applied to the top plate portion of the lid during stacking, the top plate portion bends and deforms, and for example, the stacked load is applied to the plate-like body that is held and stored by the top plate portion. Therefore, there is a possibility that the plate-like body may be cracked or broken. However, in the case of the present invention, the plate-like body B is not subjected to a stacking load as described above, and there is no concern about the above. .

  Further, in the stacked state, whether or not the stacked containers are displaced by checking the position of the side wall 21 of the cutout groove 20 by looking through the cutout portion 35 opened to the side surface, It can be easily confirmed whether or not the fitting convex portion 18 is normally fitted to the support wall portions 34a, 34b, 34c, and 34d. And if it is misaligned, it can be stacked in a normal mating state by correcting the misalignment and re-stacking, and maintains a stable stacking state without increasing the mating depth. it can.

  FIGS. 11-13 has shown the example of a change of the container for conveyance of the plate-shaped object of this invention. The transport container A of this embodiment basically has the same configuration as that of the first embodiment described above, and therefore, the same reference numerals are given and detailed description thereof is omitted, and the difference from the first embodiment. The explanation will be focused on.

  In the case of the second embodiment, two cutout portions 35 are provided at intervals between one of the support wall portions 34a, 34b, 34c, 34d of the upper surface 3a of the lid 3 and the support wall portions 34a, 34c. At the same time, the fitting protrusion 18 provided on the lower surface 11a of the bottom 11 of the container body 1 is formed with two notch grooves 20 for linearly communicating both notch portions 35, 35 facing each other during stacking. Accordingly, the fitting convex portion 18 is fitted between the two notch portions 35, 35 inside the supporting wall portions 34a, 34c on one opposite side, and the first fitting convex portion 18-1, It is divided into second fitting convex portions 18-2 and 18-2 that fit inside the supporting wall portions 34b and 34d on the other opposite sides. And the said 1st fitting convex part 18-1 is a plane H shape which has the cross-over part 18-1b between the both-ends parts 18-1a and 18-1c which contact | abut to the support wall parts 34a and 34c of opposing both sides. None, and the convex portion 36 of the lid upper surface 3a is divided and formed so as to be fitted to the non-projecting portions 19 on both sides of the crossover portion 18-1b at the time of stacking.

  Also in this embodiment, the side wall 21 of the notch groove 20 formed by the edges of both end portions 18-1a and 18-1c of the first fitting convex portion 18-1 and the edge of the convex portion 36 is provided. In a normal stacked state, it is formed so as to be positioned at a predetermined position within the width of the notch 35, for example, at the center, and by checking the position of the side wall 21 through the notch 35 during stacking, The presence or absence of misalignment can be confirmed.

  Further, in the case of the second embodiment, the support wall portions 34b and 34d on both opposite sides on the other short side are also formed with two notches 37 spaced apart in the longitudinal direction of the side, The second fitting convex portions 18-2 and 18-2 that fit inside the support wall portions 34b and 34d have a notch groove 23 that is continuous from the notch groove 20 and communicates with the notch portion 37 during stacking. The at least one side wall 24 of the cutout groove 23 is formed at a predetermined position within the width of the cutout portion 37, for example, at the center, and the side wall 24 passes through the cutout portion 37 during stacking. By confirming the position, it is possible to confirm the presence / absence of the misalignment.

  That is, in the case of the transport container A of the second embodiment, in the stacked state, it is possible to confirm the positional deviation in both the vertical and horizontal directions from the vertical and horizontal cutout portions 35 and 37. In addition, when stacking, the fitting convex portion 18 of the bottom lower surface 11a of the upper container body 1 is formed between the support wall portions 34a, 34b, 34c, 34d of the lower lid upper surface 3a and the central convex portion 36. By fitting to both, the effect of restricting positional deviation in both the front, rear, left and right directions is increased, and a stable stacked state can be maintained.

  Moreover, in the stacked state, similarly to the first embodiment, the peripheral edge 17 of the bottom lower surface 11a of the upper container body 1 can be received by the support wall portions 34a, 34b, 34c, 34d, It is possible to prevent a stacked load from acting on the top plate portion 31 of the lid 3. In particular, the protrusion height h1 of the fitting convex portion 18 and the protrusion height h3 of the convex portion 36 on the bottom lower surface 11a of the container body 1 are lower than the protrusion height h2 of the support wall portions 34a, 34b, 34c, 34d. As a result, the stacking load can be stacked without acting on the top plate portion 31 of the lid 3.

  In addition, as a constituent material of the said container main body 1 and the cover body 3, although arbitrary synthetic resin foams can be utilized, it is preferable that it is a foaming molding body of a thermoplastic resin. Thermoplastic resins include polystyrene resins, polyolefin resins (eg, polypropylene resins, polyethylene resins), polyester resins (eg, polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate), polycarbonate resins, polylactic acid resins, etc. Can be mentioned. Among these, it is preferable to use a composite resin containing polystyrene and polyethylene. The foaming ratio of the foam is preferably 3 to 50 times.

  The transport container of the present invention can be suitably used for transporting and storing relatively large glass substrates such as glass plates for glass, liquid crystal displays and plasma displays, and other various plate-like bodies that are vulnerable to impact. .
