  The present invention relates to a buffer packaging material disposed inside a packaging box for packaging an article to be packaged, or a buffer for related members bundled in an apparatus main body, particularly a space created in an image forming apparatus main body. It relates to packaging materials.

  Articles such as image forming apparatuses, household electric appliances, and functional members and electronic parts constituting them are usually packaged and shipped in a packaging box made of cardboard or the like. Many of the packaging boxes have a form in which an article to be packaged is completely accommodated in a cardboard box. In order to protect the package from impact during transportation, the package is often housed in a packaging box via a buffer packaging material.

  When a plurality of items to be packaged are accommodated in a single packaging box, or a space is provided between the packaging box and the packaged item, a buffer packaging material is disposed inside the packaging box. The This shock-absorbing wrapping material provides a buffering action so that a plurality of items to be packaged in the packaging box do not collide with each other, or the packaged item does not move greatly due to the impact of the packaging box and collide with the inner wall. It is. In this way, the cushioning packaging material protects the articles to be packaged contained in the packaging box from damage.

An example of the buffer packaging material as described above can be seen in Patent Document 1. The corrugated packaging material (buffer packaging material) described in Patent Document 1 is formed into a substantially cylindrical shape by bending upwards two opposing sides of one rectangular plate-shaped member and then bending it further inward. The packaging material body is formed.

  Prior to the description of the buffer wrapping material, a detailed configuration of the in-body paper discharge unit 16 that is a paper discharge space of the image forming apparatus 1 will be described.

  As shown in FIG. 1, the in-body sheet discharge unit 16 is disposed above the position where the exposure device 10 and the toner container 12 are disposed in the main body 2 of the image forming apparatus 1 and below the image reading unit 7. Has been. That is, the in-body paper discharge unit 16 is built in the main body 2 with a structure on the upper side and the lower side. Therefore, it is not necessary to provide a paper discharge tray or the like so as to protrude outward from the side surface of the main body 2. This contributes to the compactness of the forming apparatus 1.

  As shown in FIG. 2, the in-body paper discharge portion 16 is a paper discharge space in which a front surface opening portion 16 a is provided on the front side of the main body 2 and a side surface opening portion 16 b is provided on the right side surface. The printed paper P can be taken out from the front side or the right side of the main body 2 by putting the hand into the in-body paper discharge unit 16.

  As shown in FIG. 3, the buffer wrapping material 20 is disposed in the in-body paper discharge portion 16 which is such a paper discharge space. The buffer wrapping material 20 can be stored and taken out from the front of the in-body paper discharge unit 16 and can be easily attached and detached.

  The buffer wrapping material 20 has a substantially rectangular parallelepiped shape, and is formed so that it fits snugly inside the in-body paper discharge portion 16. The buffer packaging material 20 includes a base member 30 and a lid member 40. A related member of the image forming apparatus 1 such as a toner container (not shown) can be accommodated as an object to be packaged in an accommodation space inside the cushioning packaging material 20 surrounded by the base member 30 and the lid member 40.

  As shown in FIG. 5, the base member 30 has a bowl shape including a bottom surface portion 31 and two opposing buffer portions 32 and 33 formed adjacent to the bottom surface portion 31. The article to be packaged is placed at the center of the inner bottom surface of the base member 30.

  When the base member 30 is expanded, a development view shown in FIG. 6 is obtained. The base member 30 is a member having a substantially rectangular plate shape in the unfolded state, and is made of cardboard. In FIG. 6, the length in the left-right direction of the bottom surface portion 31 of the base member 30 in the state of a rectangular plate member substantially matches the length in the left-right direction of the in-body sheet discharge portion 16, and the length in the vertical direction of the bottom surface portion 31. Is substantially equal to the length of the in-body sheet discharge portion 16 in the front-rear direction.

  At the fold 32a of the base member 30, its outer portion is bent substantially vertically upward, further folded at the fold 32b so as to be substantially horizontal inward, further folded at the fold 32c, substantially vertically downward, and further at the fold 32d. The buffer portion 32 is formed by bending outward (see FIG. 5). Similarly, the buffer part 33 is formed by bending at the fold lines 33a to 33d.

  In this way, the buffer portions 32 and 33 are formed at two opposite sides of the rectangular plate-like member located on the left and right in FIG. As shown in FIG. 5, the buffer portions 32 and 33 have a rectangular tube shape that is tilted sideways. When the buffer wrapping material 20 is stored in the in-body paper discharge unit 16, the buffer parts 32 and 33 extend in the front-rear direction on the right and left sides in the in-body paper discharge unit 16 as shown in FIG. 3.

  When the buffer wrapping material 20 is stored in the in-body paper discharge portion 16, the upper surface of the buffer wrapping material 20, particularly the upper surface of the buffer portion 32 adjacent to the side surface opening portion 16b on the right side of the main body 2 is in the in-body paper discharge portion 16. The bottom surface of the buffer packaging material 20, particularly the bottom surface portion 31 facing the contact portion on the top surface side of the buffer portion 32, is in contact with the bottom surface in the in-body sheet discharge portion 16. . Thereby, the buffer packaging material 20 is suppressing that the location of the right front side of the image reading part 7 falls by the impact at the time of conveyance. Further, the cushioning packaging material 20 also prevents the operation panel 9 that can swing up and down on the tip side from being lowered.

  As shown in FIG. 6, the bottom surface portion 31 of the base member 30 is provided with locking pieces 34 at three locations. The locking piece 34 is formed of a cut-and-raised piece that rises upward with respect to the bottom surface portion 31 from the inner side toward the outer side. The locking piece 34 has a trapezoidal shape that extends upward from its base. As shown in FIG. 5, the base portion of the locking piece 34 corresponds to the position of the vertical wall inside the buffer portions 32 and 33. Of the three locking pieces 34, one corresponds to the buffer part 32 and the other two correspond to the buffer part 33.

  Corresponding to these locking pieces 34, engagement holes 35 are provided in the vertical walls inside the buffer portions 32 and 33. The engagement hole 35 has a trapezoidal shape like the locking piece 34 and is configured to have a size capable of receiving the locking piece 34.

  When the buffer portions 32 and 33 are formed, the locking pieces 34 are inserted and held in the engagement holes 35 in the final stage of the formation, and the shapes of the buffer portions 32 and 33 are adjusted.

  Further, as shown in FIG. 5, the buffer portion 33 includes a sub-accommodating portion 36 at a substantially central portion in the front-rear direction. The sub-accommodating portion 36 is formed by bending the two side wall pieces 37 (see FIG. 6) cut into the upper surface of the buffer portion 33 downward. The sub-accommodating portion 36 can accommodate a relatively small member.

  As shown in FIG. 7, the lid member 40 includes an upper surface portion 41 and two opposing side walls 42 formed adjacent to the upper surface portion 41. The lid member 40 covers the upper part of the article to be packaged placed at the center of the inner bottom surface of the base member 30.

  When the lid member 40 is developed, a development view shown in FIG. 8 is obtained. The lid member 40 is a member having a substantially rectangular plate shape in the unfolded state, and is made of cardboard. The upper surface portion 41 is provided with a portion covering the upper side of the sub housing portion 36 of the base member 30 adjacent to the left side in FIG. 8 with respect to the portion corresponding to the main member housing space of the base member 30.

  By folding the outer portion downward at the fold line 42a of the lid member 40, the side wall 42 perpendicular to the two opposing sides located in the up and down direction in FIG. 8 is formed (see FIG. 7). When the buffer wrapping material 20 is stored in the in-body paper discharge unit 16, the side wall 42 extends in the left-right direction on the front side and the back side in the in-body paper discharge unit 16, as shown in FIG. 3. That is, the two side walls 42 correspond to two sides orthogonal to the buffer portions 32 and 33 of the base member 30 and face each other.

  As shown in FIG. 8, a handle portion 43 is provided at a substantially central portion in the left-right direction of the fold line 42a. The handle portion 43 is formed so as to extend back and forth by cutting and raising as the side wall portion 42 is bent downward (see FIG. 7).

  Further, a projecting piece 44 is provided at the lowermost end of the front side wall 42. The protruding piece 44 is provided at a substantially central portion in the left-right direction of the side wall 42 and extends downward together with the side wall 42.

  The lid member 40 having the above configuration is coupled to the base member 30 from above as shown in FIG. Therefore, the buffer portions 32 and 33 of the base member 30 are provided with slits 38 at locations corresponding to the side walls 42 of the lid member 40 as shown in FIG. The slits 38 are provided at a total of four locations, two at each of the buffer portions 32 and 33, and extend downward from the upper surface of the buffer portions 32 and 33 and the upper end of the inner side wall at a predetermined depth. When the lid member 40 is coupled to the base member 30, the left and right ends of the side wall 42 are fitted into the slits 38 as shown in FIG. 4.

  Furthermore, as shown in FIG. 5, a through-hole 39 is provided in a location corresponding to the protruding piece 44 provided on the side wall 42 on the front surface side of the lid member 40 in the bottom surface portion 31 of the base member 30. The through hole 39 has a rectangular shape and is large enough to accept the protruding piece 44. When the lid member 40 is coupled to the base member 30, as shown in FIGS. 4 and 9, the projecting piece 44 passes through the through hole 39 and penetrates the bottom surface portion 31 of the base member 30 and projects downward.

  When the buffer packaging material 20 shown in FIG. 4 in which the base member 30 and the lid member 40 have been combined is accommodated in the in-body paper discharge portion 16 of the image forming apparatus 1, the front side is the in-body paper discharge portion 16. Therefore, the protruding piece 44 does not come into contact with the bottom surface of the in-body sheet discharge portion 16 (see FIG. 3).

  Here, when the shock-absorbing packaging material 20 is taken out from the in-body paper discharge unit 16 of the image forming apparatus 1 and placed on the floor surface, the protruding pieces 44 are formed before the outer bottom surface of the shock-absorbing packaging material 20 contacts the floor surface. The front end abuts, and the entire lid member 40 is pushed up as shown in FIG.

  As described above, the buffer packaging material 20 includes the base member 30 having the buffer portions 32 and 33 formed adjacent to the bottom surface portion 31 by bending upward the two opposite sides of the rectangular plate member. The base member 30 is coupled to the base member 30 from above to form a member accommodating space. The rectangular plate-like member corresponds to the two sides orthogonal to the buffer portions 32 and 33, and the opposite portions are directed downward. And a lid member 40 having a side wall 42 formed adjacent to the upper surface portion 41 by bending, and the lid member 40 protrudes downward through the bottom surface portion 31 of the base member 30 at the lowermost end of the side wall 42. Since the cushioning packaging material 20 having a rectangular parallelepiped shape is formed with the base member 30 on the two opposing side surfaces and the lid member 40 on the other two side surfaces, the four sides of the member housing space are formed. Can surround And it is possible to form simply by coupling the lid member 40 and the structure on the base member 30. Thereby, the shock-absorbing packaging material 20 with an enhanced shock-absorbing action can be easily assembled. Furthermore, when the buffer packaging material 20 is taken out from a packaging box or the like and placed on a floor or a desk, the projecting piece 44 is pushed up and the lid member 40 is automatically raised. Therefore, the effort which removes the cover member 40 at the time of unpacking can be reduced. In this way, it is possible to obtain the shock-absorbing packaging material 20 in which the workability related to assembly and unpacking is improved while sufficiently retaining the shock-absorbing performance.

  Moreover, since the side wall 42 fits into the slit 38 provided in the buffer parts 32 and 33 and couple | bonds with the base member 30, the lid member 40 is connected to the base member 30. It is possible to further increase the strength. Thereby, in the buffer packaging material 20 in which the workability related to assembling and unpacking is improved, it is possible to further improve the action of protecting the package.

  And since the buffer parts 32 and 33 make a cylinder shape, it is possible to form the buffer parts 32 and 33 more effective regarding the buffer performance with respect to a to-be-packaged object. Therefore, in the cushioning packaging material 20 in which the workability related to assembling and unpacking is improved, the function of protecting the package can be further improved.

  The shock-absorbing packaging material 20 of the present invention includes an in-body paper discharge portion 16 that is a paper discharge space that is built in the main body 2 with structures on the upper and lower sides and has a front opening 16a on the front side of the main body 2. The so-called in-cylinder discharge type image forming apparatus 1 is disposed in the in-body paper discharge unit 16 of the provided image forming apparatus 1 and is detachable from the in-cylinder paper discharge unit 16. In this case, it is possible to use the in-body paper discharge unit 16 to package the related members housed in the cushioning packaging material 20 in a compact manner while protecting them from impact during transportation. Therefore, when forming the cushioning packaging material 20 that can be disposed in the in-body paper discharge unit 16 of the in-body type image forming apparatus and can store the related members therein, the buffer performance is sufficiently maintained. In addition, it is possible to obtain the cushioning packaging material 20 in which the workability related to assembly and unpacking is further improved.

  Further, the cushioning packaging material 20 of the present invention has the cushioning portion 32 of the base member 30 in contact with the upper surface of the in-body sheet discharge portion 16 of the image forming apparatus 1 and the bottom surface portion 31 facing the contacted portion. Since the location is in contact with the bottom surface of the in-body paper discharge unit 16, the buffer unit 32 causes the image reading unit 7 and the operation panel 9 that are structures provided above the in-body paper discharge unit 16 to be displaced downward. Can be prevented. As a result, the buffer packaging material 20 is effective in preventing damage to the image forming apparatus 1 in addition to preventing damage to related members housed therein. Therefore, it is possible to further improve the cushioning performance of the cushioning packaging material 20 in which the workability related to assembly and unpacking is improved.

  Next, the structure of the buffer packaging material according to the second embodiment of the present invention will be described with reference to FIG. FIG. 11 is a perspective view of the entire cushioning packaging material. Since the basic configuration of this embodiment is the same as that of the first embodiment described with reference to FIGS. 1 to 10, the same reference numerals are used for the same components as those of the first embodiment. The description is omitted.

  The shock-absorbing packaging material 20 according to the second embodiment is accommodated in the packaging box 100 drawn by a two-dot chain line in FIG. A support portion 101 is formed at a position corresponding to the buffer portions 32 and 33 of the base member 30 at the inner lower portion of the packaging box 100. The support portion 101 is formed in a rectangular tube shape that is tilted sideways, and has a height that is higher than the protruding length of the protruding piece 44 with respect to the outer bottom surface of the cushioning packaging material 20. Accordingly, as shown in FIG. 11, even when the buffer packaging material 20 is stored in the packaging box 100, the protruding piece 44 does not contact the inner bottom surface of the packaging box 100.

  In this way, in forming the shock-absorbing packaging material 20 that can be placed in the packaging box 100 and that can accommodate the packaged goods inside, the shock-absorbing performance is sufficiently maintained and further assembled and opened. The cushioning packaging material 20 in which the workability related to bundling is improved can be obtained.

  Although the embodiments of the present invention have been described above, the scope of the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the invention.
