Description

  The present invention relates to a buffer unit including a buffer member or the like used to protect a packaged object that is a packaged item when a product (packaged object) such as an electronic device is stored in a packaging box.

  When products such as electronic devices (for example, copy machines) are marketed, they are accommodated in a packing box made of cardboard or the like. In general, as shown in FIG. 8, a buffer member 102 is interposed between the packing box 110 and the electronic device 100 in order to absorb shocks, vibrations, and the like with respect to the stored electronic device 100. (See Patent Document 1).

  As a material of such a buffer member 102, a molding material such as a polystyrene foam resin having high absorbability such as shock and vibration is used. The expanded polystyrene resin has high absorbability such as impact and vibration, and is easy to be molded (deformed) into various shapes. Therefore, it is easy to produce the buffer member 102 that completely matches the shape of the corner (corner) of the exterior in the electronic device 100. Then, when receiving an impact or the like, it is possible to efficiently protect the corners and the like of the electronic device 100 that is most easily damaged.

  However, when the foamed polystyrene resin cushioning member 102 is used for the packaging box 110 made of cardboard, after taking out the product of the electronic device 100 or the like from the packaging box 110, from the viewpoint of recycling them (the packaging box 110 made of cardboard and The necessity of separating the cushioning member 102) made of expanded polystyrene resin arises.

Such separation is extremely troublesome. For this reason, recently, the cushioning member 102 itself is also made of cardboard.
JP 2002-104395 A (see FIG. 2)

  However, since corrugated cardboard or the like is inferior in moldability as compared with foamed polystyrene resin or the like, it is difficult to form a buffer member that completely matches the shape of the corner or the like of the electronic device 100. Therefore, when an impact, vibration, or the like is applied, the buffer member 102 is easily dropped from the corner of the electronic device 100 or the like. In addition, as shown in FIG. 9, when an impact or the like is applied, the cardboard or the like is easily deformed, and the buffer member 102 is easily dropped from the electronic device 100 or the like.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a buffer unit that can prevent the buffer member from falling off the packaged object.

  The present invention is a buffer unit configured to include a plurality of buffer members interposed between the packed object and the packing box in order to protect the packed object packed in the packing box from impact, A cross-linking member that connects the plurality of buffer members is provided.

  Specifically, the buffer member is provided with an opening, and the bridging member is provided with a protrusion. The protrusion is fitted into the opening, so that the buffer member becomes a bridge member. It is preferable that they can be connected via each other.

  According to this, the buffer members are connected via the bridging member. Then, the buffer members that have been installed separately form a series. In this way, when the buffer members are in a series, even if one of the buffer members is likely to drop off from the packaged object such as an electronic device, the other buffer member is likely to drop off via the bridging member. The buffer member is retained. As a result, it is possible to prevent the shock-absorbing member from dropping from the packaged item.

  In the buffer unit of the present invention, it is preferable that a recess into which a part of the bridging member including the protruding portion is fitted is formed at a position where the opening is provided in the buffer member.

  When such a depression is provided, the bridging member can be sandwiched by two buffer members, and the inner wall of the depression sandwiches the outer wall of the bridging member. Then, the movement of the outer wall of the bridging member in the direction in which the buffer members approach each other is suppressed. Therefore, the force can be dispersed also on the outer wall of the bridging member without applying a force only to the protruding portion of the bridging member.

  Therefore, the deformation of the protrusion due to the movement of the buffer member is prevented, and the force is distributed to the outer wall of the bridging member. Therefore, it is possible to prevent a situation where the bridging member and the buffer member are separated (for example, it is possible to prevent a situation in which a force is excessively applied to the protrusion and the protrusion is detached from the opening).

  In the buffer unit of the present invention, it is preferable that the bridging member has a plurality of standing portions, and a space surrounded by the standing portions is an accommodable region.

  When such an accommodation area (accommodation space) is provided in the bridging member, it is possible to accommodate books such as instruction manuals for electronic devices and the like and equipment (wiring, etc.) in this space. In other words, it can be said that the bridging member that can accommodate books and fixtures serves as a storage tray, and this storage tray is useful for preventing the buffer member from falling off.

  The buffer unit of the present invention can prevent the buffer member from falling off from an object to be packed such as an electronic device.

  An embodiment of the present invention will be described below with reference to the drawings.

[Embodiment 1]
[Configuration of buffer unit]
As shown in FIG. 2, the buffer unit 1 includes a buffer member 2 and a bridging member 4. And when this electronic device etc. (copy machine etc.) 10 is inserted in the packing box 11, this buffer unit 1 is a part around the exterior in the electronic device etc. 10 (for example, corners of the electronic equipment etc. 10) etc. It comes to cover. That is, the buffer unit 1 is configured such that a plurality of buffer members 2 are interposed between the electronic device 10 or the like 10 to be packed and the packing box 11.

<About buffer member>
The buffer member 2 is a member made of paper such as cardboard. As shown in FIG. 2, in order to protect the electronic device or the like (packaged object) 10 from an impact or the like, an exterior portion of the electronic device or the like 10, for example, a corner (corner) of the electronic device or the like 10 is covered. Yes. In particular, the buffer member 2 has a shape that matches the exterior of the electronic device 10 or the like.

  In addition, the buffer member 2 is provided with an opening 3 for inserting a projection 5 of a bridging member 4 described later. The position and shape of the opening 3 are not particularly limited, but it is preferably provided so as to be concave from one surface of the buffer member 2 that supports the bridging member 4 described later.

<About cross-linked members>
The bridging member 4 is a member made of paper or the like, like the buffer member 2, and is bridged between the buffer members 2. Specifically, the protrusion 5 is provided on the bridging member 4, and the protrusion 5 is fitted into the opening 3 described above.

  The bridging member 4 itself is composed of a sheet of cardboard as shown in FIG. In this figure, the two-dot chain line is a fold line and is bent toward the center (the center of the bottom plate 8 of the single bridge member 4 shown in the figure). The solid line is a cutting line.

  Then, in this sheet of cardboard or the like, a Katakana U-shaped cut (a U-shaped cutting line 5a) can be inserted so as to sandwich the center (for example, at both ends in the longitudinal direction of the cardboard). ing. Specifically, the intermediate sides 5ab and 5ab of the U-shaped cutting line 5a face each other and maintain a parallel relationship, and the opening of the U-shaped cutting line 5a faces the outer end side of the cardboard.

  And the 1st fold line (1st fold line) 6a * 6a is formed along the line | wire which connects the both ends in each U-shaped cutting line 5a. Then, bent pieces (first bent pieces) 6 and 6 are formed on the outer side (outer end side of the cardboard) from the first bent lines 6a and 6a.

  Subsequently, the second fold lines (second fold lines) 7a and 7a are formed by connecting ends of the two first fold lines 6a and 6a facing each other. . Specifically, the ends of the first fold lines 6a and 6a are connected to each other so as to be perpendicular to the first fold lines 6a and 6a. Then, bent pieces (second bent pieces) 7 and 7 are formed on the outer side (outer end side of the cardboard) from the second bent lines 7a and 7a.

  Then, along the first fold lines 6a and 6a and the second fold lines 7a and 7a, the first fold pieces 6 and 6 and the second fold pieces 7 and 7 are bent toward the center of the cardboard or the like. It is like that. Then, as shown in FIG. 4, the first bent pieces 6, 6 and the second bent pieces 7, 7 rise (become erected) with respect to the bottom plate 8 such as cardboard. The portions of the character cutting lines 5a and 5a stand up with respect to the bottom plate 8 such as cardboard in the direction opposite to the direction in which the first bent pieces 6 and 6 and the second bent pieces 7 and 7 rise. The rising angle is substantially perpendicular (90 °) to the bottom plate 8.

  Then, as shown in FIG. 4, an accommodation region surrounded by the bottom plate 8, the first bent pieces 6, 6 (standing portion), and the second bent pieces 7, 7 (standing portion) is formed, The portions of the U-shaped cutting lines 5a and 5a are folded up to become protrusions 5 and 5. That is, on the one end surface side (for example, the front surface side) on the plane of the bottom plate 8, on the other end surface side (the back surface side) Protrusions 5 and 5 to be inserted into the openings 3 of the buffer member 2 are formed.

  In addition, it is more preferable that the steps D and D are provided in the lines of the two short sides 5ac and 5ac in the U-shaped cutting line 5a. If the steps D and D are provided in this way, it is easy to catch the opening 3 when the protrusion 5 is inserted into the opening 3 of the buffer member 2. That is, the step D is easily caught on the end of the opening 3.

[About connection between buffer member and bridging member]
The connection between the completed bridging member 4 and the buffer member 2 will be described with reference to FIG. 1 (an enlarged view of the portion α in FIG. 2). The buffer member 2 is provided with the opening 3 described above. Then, the protrusion 5 of the bridging member 4 is inserted into the opening 3. In addition, the bottom surface 8 of the bridging member 4 is supported by one surface of the buffer member 2 when the protrusion 5 is inserted into the opening 3.

  In this way, when each of the protrusions 5 of the bridging member 4 is inserted into the respective openings 3 of the two buffer members 2, the two buffer members 2 are connected via the bridging member 4 (connection). Will come to be).

[Various features of the buffer unit]
As described above, the buffer unit 1 of the present invention is characterized in that the bridging member 4 that connects the plurality of buffer members 2 to each other is provided. Specifically, the shock-absorbing member 2 is provided with an opening, and the bridging member 4 is provided with a protrusion. The protrusion 5 is fitted into the hole 3 so that the shock-absorbing member 2 is cross-linked. It can be connected via the member 4.

  When the buffer members 2 are connected to each other via the bridging member 4, for example, the buffer members 2 that are separately installed at each end of the corner of the exterior of the electronic device 10 or the like become a series. Thus, when the buffer member 2 is in a series, even if one of the buffer members 2 is likely to fall off the electronic device 10 or the like, the other buffer member 2 is likely to drop off via the bridging member 4. The buffer member 2 is retained. As a result, it is possible to prevent the shock-absorbing member 2 from dropping from the packaged object 10 such as an electronic device.

  In addition, the buffer unit 1 according to the present invention is configured to include a plurality of buffer members 2 while preventing dropout. Then, the plurality of buffer members 2 are easier to attach to the exterior of the electronic device 10 or the like than when handling a single large buffer member. As a result, the present invention is a buffer unit 1 with high workability.

[Embodiment 2]
A second embodiment of the present invention will be described. In addition, about the member which has the same function as the member used in Embodiment 1, the same code | symbol is attached and the description is abbreviate | omitted.

  In the first embodiment, the protrusion 5 provided on the bridging member 4 is inserted into the opening 3 provided on the buffer member 2 in order to prevent the buffer member 2 from dropping off from the article to be packed of the electronic device 10 or the like. Both (the bridging member 4 and the buffer member 2) are connected.

  In this way, the buffer member 2 and the bridging member 4 that are connected (in a series) are more difficult to drop out than the buffer member 2 that is simply placed at the corner of the electronic device 10 or the like. ing. However, as shown in FIG. 1, when the cushioning member 2 is connected only by inserting the projection 5 into the opening 3, the connection strength between the two (the cushioning member 2 and the bridging member 4) is as follows. It depends only on the intensity of the.

  Then, when a situation occurs in which the buffer member 2 is moved in the center direction of the electronic device 10 or the like for some reason, the protrusion 5 may be deformed. And when such a deformation | transformation of the projection part 5 arises, the connection strength of both (the buffer member 2 and the bridge | crosslinking member 4) may fall.

  Therefore, in order to prevent the protrusion 5 from being deformed due to the movement of the buffer member 2 and to further enhance the connectivity between the two (buffer member 2 and bridging member 4), the buffer member 2 is provided with FIGS. As shown in FIG. 5 (partially enlarged view)), the shape of the recess 15 that matches the outer shape of the bridging member 4 is provided. Specifically, a recess 15 into which a part of the bridging member 4 including the protrusion 5 (for example, both ends of the bridging member 4) is fitted is formed at the location where the opening 3 is provided in the buffer member 2. Yes.

  For example, as shown in FIG. 5, the recess 15 may have a shape that matches the outer shape of a part of one of the bridging members 4 and both short sides, as shown in FIG. 7. As described above, the cross-section of the bridging member 4 may have a shape that matches the outer shape of both the long sides and the short sides.

  When such a depression 15 is provided, the bridging member 4 can be sandwiched by the two buffer members 2, and the inner wall of the depression 15 is the outer wall of the bridging member 4 (for example, the first bent pieces 6 and 6, the second The bent pieces 7 and 7) are sandwiched. That is, the movement of the outer wall of the bridging member 4 in the direction in which the buffer members 2 approach each other is suppressed. Therefore, the force is not applied only to the projection 5 of the bridging member 4, but the force is also distributed to the outer wall of the bridging member 4.

  Therefore, deformation of the protrusion 5 due to the movement of the buffer member 2 can be prevented. Further, since no force is applied only to the protrusion 5 and the force is also distributed to the outer wall of the bridging member 4, a situation where the bridging member 4 and the buffer member 2 are separated can be prevented (for example, excessively the protrusion 5 can prevent a situation in which a force is applied to 5 and the protrusion 5 is detached from the opening 3).

[Other embodiments]
The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, the number of bridging members 4 is not particularly limited, and may be one or more.

  In the above description, the cushioning member 2 and the bridging member 4 made of cardboard have been described. However, the cushioning member 2 and the bridging member 4 made of other materials may be used.

  The buffer unit of the present invention is effective when used for a packing box when packing an object such as an electronic device.
