Description

  The present invention relates to a packing structure for a display device including a cushioning material and a packing box used when a thin display device such as a liquid crystal television is conveyed.

  2. Description of the Related Art Thin display devices (hereinafter referred to as “display devices”) typified by liquid crystal televisions and PDP televisions in recent years have been increasing in size with the increase in screen size. As the display device increases in size, the depth dimension of the stand fixed to the main body having the display surface increases, and the depth dimension of the packaging box used when the display apparatus is transported also increases. Increasing the size of the display device causes a reduction in product packaging efficiency and conveyance efficiency, which increases not only the cost of the packaging box but also the conveyance cost. Moreover, since the packaging box which becomes unnecessary after the unpacking of the product is enlarged, the disposal cost of the packaging box increases.

  From this situation, the main unit and stand can be separated, and the main unit and stand can be self-supported using cushioning material, reducing the packing volume and improving packing efficiency. Various display device packaging structures are known.

  Specifically, the packing box has a rectangular parallelepiped shape that is extremely thin in the depth direction with respect to the width direction and height direction of the main body of the display device. To reduce costs.

  On the other hand, since the depth direction becomes extremely thin with respect to the width direction and the height direction of the packaging box, the weight balance due to the arrangement of the main body portion and the stand at the time of packaging deteriorates. Since the fall direction in the depth direction in the packing state is smaller than that of the conventional thick packing box, the stability in the packing state is deteriorated. Due to the force applied when the main body and the stand are taken out of the packaging box during unpacking, the packaging box itself cannot be maintained independently, and the possibility that the packaging box will easily fall is increased.

  For example, Patent Documents 1 to 4 disclose a packing structure for a display device for improving the above problems. The packaging structure described in Patent Document 1 is attached to both side surfaces on both sides located in the short direction of the box body in the packaging form in which the upper part of the packaging box is opened and the packing form disposed on the inner bottom of the box body. The packing structure has a fall prevention member that can project from each side surface in the lateral direction.

  The packaging structure described in Patent Document 2 is composed of three members that serve as packaging materials for the packaging box. This packing structure is formed integrally with the packing material constituting the packing box body so as to be located at the lower part of the packing box body, and is projected in the depth direction of the packing box from the main surface of the packing box body. It has a structure having a blade part fastened to the packing box body.

  The packaging structure described in Patent Document 3 is formed at a portion where a side surface portion arranged around the display device and a lower surface portion on which the display device is placed intersect when the display device is packed in a packaging box. A lower support portion protruding downward from the shoulder portion and an upper support portion protruding upward from the shoulder portion formed at a portion where the side surface portion and the upper surface portion intersect with each other are provided. In this packing structure, the upper support portion and the lower support portion are alternately provided in a direction orthogonal to the vertical direction.

  In the packaging structure described in Patent Document 4, the box body is formed with a recess for storing a removable support bar and a hole for inserting the support bar, and the support bar is inserted so as to protrude from the hole. It is characterized by preventing. In addition, when it is not necessary to prevent overturning, such as when transporting or storing in a narrow place, a support bar can be stored in the recess of the box body.

  However, in the packaging structure described in Patent Document 1, since the side cushioning material is provided as a fall-preventing member, the number of parts of the packaging member also increases, and only the amount of the side cushioning material when packaging specifications do not require the side cushioning material. Packing material costs increase. In the packing box structure, since the coupling member used at the time of the structure of the C type packaging in which the bottom of the box main body and the packaging bottom box are divided into two parts, the fall prevention member needs to be coupled and fixed. The packing material cost increases by the amount.

  Since the fall prevention member is disposed on the standing wall portion in the center in the width direction of the packaging bottom box made of cardboard, when a load is applied to the fall prevention member, only the standing wall portion made of cardboard Since the strength against the load is not sufficient, it easily deforms. For this reason, in order to prevent such a deformation | transformation, it is necessary to add the member for ensuring the intensity | strength of a standing wall part, and a packaging member cost increases further by the part of the added member.

  Further, since the side cushioning material itself needs to be bent from the expanded state of the member and complicated assembling, the packing work time at the time of product packing becomes long and the work cost increases.

  Even when unpacking, remove the box body with the bottom opening, remove the side cushioning material, and then use the side cushioning material as a fall prevention member to attach to the packaging bottom box. When removing, the fall prevention member is not attached. For this reason, when removing a box main body, possibility that a product will fall down easily with the packing bottom face box is high.

  Moreover, since the packing structure is a packing structure that is a C-type packing that is divided into a box main body with an opening at the bottom and a box at the bottom of the packing, the packing material member itself is developed rather than an A-type packing with only the packing box main body. The area increases and the packaging material cost increases.

  In the packing structure described in Patent Document 2, although no separate member for preventing the fall is provided, the vane part having the fall prevention structure is provided on the flap part that constitutes the bottom part of the packing box. For this reason, the material development area of the packaging box is increased by the amount of the blade plate portion, and the material cost of the packaging box is increased. Moreover, it is necessary to fix with the coupling member used for the coupling | bonding of the three members used as the packaging material of a packaging box, and a packaging member expense rises by the part of a coupling member.

  In addition, it is necessary to form each member by folding each member from the unfolded state of the three members that are the packing materials of the packing box. Each member is provided with an overlapping portion, and the overlapping portion is shared. Holes for fastening are arranged in each member, and each member is fastened and fixed together with a coupling member to constitute a packaging box. For this reason, since folding and complicated assembly are required from the unfolded state of a single member, the packing work time at the time of product packing becomes long, and the work cost increases.

  In addition, since the joint members are fastened together, the dimensions of the holes used for the joints also need to coincide with each other after the formation of the bending of each member. Rises.

  Furthermore, because it is configured to jointly fix each member formed by bending, it is necessary to fix it with a coupling member in a state where the positions of the holes of each member are matched using a jig in a state where the member is bent, The material cost of the packaging box increases by the amount of the jig.

  Although the packaging structure described in Patent Document 2 is configured with three members, the material development dimension that configures the blade plate portion that also serves as a fall-preventing structure is increased even when configured with one member. The material cost of the packaging box increases.

  Further, since the blade parts are coupled using the coupling member, the member cost of the packaging box increases by the amount of the coupling member that is unnecessary in the A-type packaging structure having a one-member configuration.

  Although the packaging structure described in Patent Document 3 does not provide another member for preventing overturning as in the case of Patent Document 2, as the overturning preventing structure, the main surface portion and the bottom surface portion of the packaging box corresponding to the display surface of the display device The support part structure which protruded to the shoulder part which crosses is provided. Since the punched shape by slit processing is provided in the bent part that becomes the ridge line between the front side and the back side of the main surface part, and the bottom part that intersects, holes are formed in the bent part of the main surface and the bottom surface of the packaging box, Opening reduces the strength of the bent portion of the main surface and the bottom surface. For example, when a load is applied to the flat surface portion instead of the ridge line portion of the bottom surface, there is a high possibility that the packaging box is easily torn. Similarly to the case described above, the packaging box is easily torn at the bent portion that becomes the ridgeline between the main surface and the top surface.

  In addition, since the lower support part has a shape protruding downward on the bottom surface, when the packing box is moved in the packed state, the packing box is not lifted when it is slid sideways. When there is a concavo-convex part, the lower support part is easily caught. When a load is further applied in a state where the lower support portion is caught, the lower support portion is easily broken from the slit-shaped hole constituting the lower support portion.

  In addition, a support part that serves as a fall prevention structure is formed at the bent part of the main surface, bottom surface, and top surface of the packaging box, and the depth dimension of the installation surface exceeds the dimension in the depth direction (falling direction) of the thin packaging box. Since it cannot be increased, the fall angle of the packaging box cannot be increased, and the effect of preventing the fall is limited.

  In the packaging structure described in Patent Document 4, since the support rod for preventing the fall is provided as a separate member, the number of parts of the packaging member increases, and the packaging member cost increases. In addition, since the storage space for the support rod for preventing overturning requires folding and complicated assembly of the packing box, the packing work time during product packing increases, and the work cost increases.

  In addition, the bottom of the main surface of the packaging box is provided with a recess for storing the support bar and a large hole for inserting the support bar at the lower side of the side, so that the strength of the ridgeline on the bottom surface is weakened and a load is applied to the top surface. If this happens, the packing box may buckle. Furthermore, in order to form a hole for inserting the support bar, the insertion portion needs to have a double cardboard structure, which increases the development area of the packaging box itself and increases the member cost.

  Therefore, the present invention provides a display device packaging structure that can prevent the packaging box from overturning when the product is taken out while suppressing the strength reduction of the bent portions of the top and bottom surfaces of the packaging box at a low cost. The purpose is to provide.

  The packaging structure of the display device according to the present invention is a packaging structure of a display device including a main body having a display surface and a stand fixed to a lower portion of the main body, and the stand is separated from the main body. A packing box for storing the main body in a state, and a plurality of cushioning materials respectively holding corner portions of the main body in the packing box, the packing box having a lower end portion on an outer side surface of the packing box The top surface side cushioning material located on the top surface side of the packing box among the plurality of cushioning materials includes a convex portion that can be fitted into the hole portion, and the top surface side The cushioning material functions as a support portion for supporting the lower end portion of the packaging box by removing the cushioning material from the packaging box and fitting the convex portion into the hole portion.

  Another display device packaging structure according to the present invention is a display device packaging structure comprising a main body having a display surface and a stand fixed to a lower portion of the main body, wherein the stand is mounted from the main body. A packaging box for storing the body portion in a separated state; and a plurality of cushioning materials respectively holding corner portions of the body portion in the packaging box, and the top of the packaging box among the plurality of cushioning materials. The top surface side cushioning material located on the surface side includes a recess that can be fitted to the lower end portion of the side portion of the packaging box, and the top surface side cushioning material is taken out from the packaging box and the recess is removed from the packaging box. By fitting the lower end portion of the side portion, it functions as a support portion for supporting the lower end portion of the packaging box.

  According to the packaging structure of the display device according to the present invention, the top-side cushioning material functions as a support portion for supporting the lower end portion of the packaging box by taking out the convex portion from the packaging box and fitting it into the hole portion. Therefore, the packaging box is stably maintained in a self-supporting state, and the packaging box can be prevented from falling when the product is taken out.

  Moreover, since the top-side cushioning material is used as the support portion, it is not necessary to provide a separate member when preventing the packing box from overturning, and the member cost can be suppressed. By fitting the convex part of the top side cushioning material into the hole at the lower end of the outer side of the packaging box, the top side cushioning material can be easily attached to the packaging box, reducing the work cost related to installation it can. With regard to the fitting between the convex portion and the hole portion, it is not necessary to make the processing dimension accuracy of the member strict, so that the member processing cost can be suppressed. As described above, the packaging structure of the display device can be realized at low cost.

  In addition, it is not necessary to form slits in the bent parts on the top and bottom of the packing box, and a large hole for inserting the support bar is formed in the lower part of the packing box, or a recess for storing the support bar is formed. Since it does not need to provide, the strength fall of the bending part of the top | upper surface and bottom face of a packaging box can be suppressed.

  According to the packaging structure of another display device according to the present invention, the top-side cushioning material is taken out from the packaging box, and the recess is fitted to the lower end of the side of the packaging box, thereby supporting the lower end of the packaging box. Therefore, the packaging box is stably maintained in a self-supporting state, and the packaging box can be prevented from overturning when the product is taken out.

  Moreover, since the top-side cushioning material is used as the support portion, it is not necessary to provide a separate member when preventing the packing box from overturning, and the member cost can be suppressed. By fitting the concave portion of the top surface side cushioning material to the lower end portion of the side portion of the packaging box, the top surface side cushioning material can be easily attached to the packaging box, so that the work cost related to the attachment can be suppressed. With regard to the fitting between the lower end portion of the side portion of the packaging box and the recess, it is not necessary to make the processing dimension accuracy of the member strict, so that the member processing cost can be suppressed. As described above, the packaging structure of the display device can be realized at low cost.

  In addition, it is not necessary to form slits in the bent parts on the top and bottom of the packing box, and a large hole for inserting the support bar is formed in the lower part of the packing box, or a recess for storing the support bar is formed. Since it does not need to provide, the strength fall of the bending part of the top | upper surface and bottom face of a packaging box can be suppressed.

<Embodiment 1>
Embodiment 1 of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view of the packaging structure of the display device 1 according to the first embodiment, FIG. 2 is a perspective view of the top-side cushioning material 5 in the first embodiment, and FIG. FIG. 11 is a perspective view showing an attachment state of the top cushioning materials 5 and 6 in the packaging structure of the display device 1 according to the first embodiment.

  As shown in FIG. 1, the packaging structure of the display apparatus 1 is a structure for packaging the display apparatus 1 which is a thin display apparatus. The packaging structure of the display device 1 includes a packaging box 2 and a plurality of cushioning materials 3, 4, 5, and 6. The display device 1 includes a main body 1a having a display surface 1b and a stand 1c (see FIG. 12) fixed to the lower portion of the main body 1a. The packaging box 2 separates the stand 1c from the main body 1a. It is stored in the state.

  The buffer materials 3, 4, 5, and 6 are formed in an L shape using a foamed PS material, and hold the corner portions of the main body 1 a in the packing box 2. More specifically, the cushioning materials 3 and 4 that are the bottom surface side cushioning materials hold the corners of the lower end portion of the main body portion 1a, and the cushioning materials 5 and 6 that are the top surface side cushioning materials are of the main body portion 1a. Each corner of the upper end is held. Here, FIG. 1 shows a general A-type packing specification, and the A-type packing specification is a packing specification in which the packing box is not divided into two.

  In order to make the drawing easier to see, the stand 1c that is bundled with the main body 1a is omitted in the packing box 2, but as shown in FIG. 12, the stand 1c is vertically placed beside the main body 1a. It is bundled.

  Next, the packaging box 2 will be described. As shown in FIG. 1, the top surface of the packaging box 2 is an unpacking surface for storing and taking out the display device 1 as a product. In the packaging box 2, a left side surface 2c and a right side surface 2d are bent between a front surface 2a and a back surface 2b corresponding to the display surface 1b of the main body 1a. For example, two holes 2e and 2f are formed in the lower end portions of the left side surface 2c (outer side surface) and the right side surface 2d (outer side surface) of the packaging box 2, respectively.

  Next, the buffer materials 5 and 6 will be described. Since the buffer materials 5 and 6 have the same structure, only the buffer material 5 will be described here.

  As shown in FIG. 2, the buffer material 5 includes a convex portion 5a and a concave portion 5c. A recess 5c having a width slightly wider than the depth of the main body 1a is formed on the surface 5b of the L-shaped inner portion of the cushioning material 5 and can be fitted to the corner of the main body 1a. By fitting the recess 5c of the cushioning material 5 into the corner of the main body 1a, the cushioning material 5 holds the corner of the main body 1a. Here, the recess 5 c is formed not only in the buffer materials 5 and 6 but also in the buffer materials 3 and 4.

  For example, two protrusions 5 a are provided on the surface 5 b of the L-shaped inner portion of the cushioning material 5. The convex part 5a is formed in a slightly smaller dimension than the hole parts 2e and 2f of the packaging box 2, and can be fitted to the hole parts 2e and 2f. Here, the convex part 5a may be formed also in the buffer materials 3 and 4, and may not be formed.

  In addition, although the case where the packaging box 2 is A type packaging specification was demonstrated, the C type packaging specification used as 2 division of a box main body and a packaging bottom face box may be sufficient. Moreover, although the buffer materials 3, 4, 5, and 6 have been described as being formed using the foamed PS material, they may be formed using a corrugated cardboard material.

  Next, a method for attaching the cushioning materials 5 and 6 to the packing box 2 will be described. As shown in FIG. 3, from the packaged state, the operator opens the top surface of the packaging box 2 when unpacking the product, and holds the cushioning material 5 holding the left and right corners of the upper end of the main body 1a. , 6 are taken out of the packing box 2. The operator puts the convex portions 5a and 6a of the cushioning materials 5 and 6 in the holes 2e and 2f (see FIG. 1) at the lower end portions of the outer side surfaces 2c and 2d of the packaging box 2, respectively. Install 5 and 6 on the floor. Thus, by fitting the convex portions 5a and 6a of the cushioning materials 5 and 6 into the holes 2e and 2f of the packaging box 2, the cushioning materials 5 and 6 are attached to the lower end of the packaging box 2, It functions as a support part for supporting the lower end part of the packaging box 2.

  The cushioning materials 3 and 4 have a concave shape that does not interfere with the convex portions 5a and 6a of the cushioning materials 5 and 6 so as not to interfere with the mounting of the cushioning materials 5 and 6 on the portion corresponding to the inner surface of the packing box 2 Have

  Next, the fall prevention effect of the packaging structure of the display device 1 according to the first embodiment will be described in comparison with the case of the packaging structure of the display device 1 according to the prerequisite technology. FIG. 4 is a schematic diagram showing a fall angle of the packing box 2 in the packing structure of the display device 1 according to the first embodiment, and FIG. 11 is an exploded view showing an example of the packing structure of the display device 1 according to the base technology. FIG. 12 is an exploded perspective view showing another example of the packaging structure of the display device 1 according to the base technology. FIG. 13 is a perspective view of the packaging box 2 in the packaging structure of the display device 1 according to the base technology. It is a schematic diagram which shows a fall angle.

  First, the packaging structure of the display device 1 according to the prerequisite technology will be described.

  As shown in FIG. 11, the thick packing box 52 has the display device 1 upright without separating the stand 1c from the main body 1a, and the corners of the main body 1a are provided with cushioning materials 53, 54, 55, It is stored in the state held by 56. As shown in FIG. 12, the thin packaging box 62 separates the stand 1c from the display device 1 so that the packaging volume is small, and the corners of the main body 1a are cushioned 63, 64, 65. , 66 and stored.

  As shown in FIG. 11, since the depth dimension d of the packaging box 52 is determined not by the depth dimension of the main body 1a but by the depth dimension of the stand 1c, the packaging volume of the packaging box 2 is increased. On the other hand, as shown in FIG. 12, the stand 1c is separated from the main body 1a and packed in a direction in which the depth of the stand 1c is minimized, so that the stand 1c has the same depth as the main body 1a. For this reason, the depth dimension d of the packaging box 62 becomes smaller than the case of FIG. 11, and a packaging volume becomes small.

  As shown in FIG. 13, in the packaging structure of the display device 1 according to the base technology, a side view of the installation state of the packaging boxes 52 and 62 is indicated by a solid line, and the packaging boxes 52 and 62 are inclined in a direction (depth direction). The side view of the state made into is shown with a dashed-two dotted line.

  By changing from the thick packaging box 52 to the thin packaging box 62, the depth dimension of the packaging box 62 is reduced, so that the center of gravity position 8a that falls from the center of gravity position 8 in the installed state of the thin packaging box 62 is provided. Is smaller than that of the thick packaging box 52. For this reason, the thin packaging box 62 has a higher possibility of falling than the thick packaging box 52.

  On the other hand, in the packaging structure of the display device 1 according to the first embodiment, by attaching the cushioning materials 5 and 6 to the packaging box 2, the depth dimension d1 of the lower end portion of the packaging box 2 as shown in FIG. Can be increased. The depth dimension d1 of the lower end portion of the thin packaging box 2 is equal to or greater than the depth dimension d of the thick packaging box 52 (see FIG. 11), and the packaging box 2 is in a stable and independent state. Can be maintained, and an effect of preventing overturning against a load applied when a product is taken out can be obtained.

  As described above, in the packaging structure of the display device 1 according to the first embodiment, the cushioning materials 5 and 6 are taken out from the packaging box 2 and are fitted into the holes 2e and 2f so as to be packed. Since it functions as a support portion for supporting the lower end portion of the box 2, the packaging box 2 is stably maintained in a self-supporting state, and the packaging box 2 can be prevented from falling when taking out the product.

  Further, since the cushioning materials 5 and 6 are used as the support portions, it is not necessary to provide a separate member when preventing the packing box 2 from overturning, and the member cost can be suppressed. By fitting the convex portions 5a and 6a of the cushioning materials 5 and 6 into the holes 2e and 2f at the lower ends of the outer side surfaces 2c and 2d of the packaging box 2, the cushioning materials 5 and 6 are easily attached to the packaging box 2. Therefore, it is possible to suppress the work cost related to the installation. With respect to the fitting between the convex portions 5a and 6a and the hole portions 2e and 2f, it is not necessary to make the processing dimension accuracy of the member strict, so that the member processing cost can be suppressed. As described above, the packaging structure of the display device 1 can be realized at low cost.

  Furthermore, it is not necessary to form slits in the bent portions of the top and bottom surfaces of the packing box 2, and a large hole for inserting a supporting bar into the lower part of the packing box 2 or for storing the supporting bar. Since it is not necessary to provide a recessed part, the strength reduction of the bending part of the top | upper surface and bottom face of the packaging box 2 can be suppressed.

  Moreover, since it is not necessary to provide the recessed part for accommodating the support rod for a fall prevention in the lower part in the packaging box 2, the enlargement of the packaging box 2 is prevented, without the bottom area of the packaging box 2 increasing. Can do.

  The holes 2e and 2f provided in the lower end portion of the outer side surface of the packaging box 2 are not formed in the packaging box 2 from the beginning, but the holes 2e and 2f are formed in the packaging box 2 as shown in FIG. A structure in which the holes 2e and 2f are formed by forming the outer shape portion by the perforation 2h and cutting the perforation 2h when the packing box 2 is opened may be used. FIG. 5 is an enlarged view of a main part showing a perforation 2h of the packaging box 2 in the modification of the first embodiment. Here, a slit may be used instead of the perforation 2h.

  Since the packing box 2 further includes a perforation 2h or a slit and the holes 2e and 2f are formed by cutting the perforation 2h or the slit, the holes 2e and 2f are closed in the packed state. , Foreign matter and fluid can be prevented from entering the packing box 2.
