Abstract

Provided is a packing material that is capable of restricting the vertical movement of an item to be packed, without a packing member pressing from above on the item to be packed. The packing material is used in conjunction with a bottom-section packing member (10) for packing the bottom section (Pb) of the item to be packed (P). The packing material (1) is provided with a pair of long, lateral-section packing members (20) for contacting the interior of a container (30) with both ends thereof, and positioned so as to face one another in the horizontal direction along lateral surfaces (Ps) of the item to be packed (P). Each lateral-section packing member (20) is formed in a manner such that the length thereof is longer than a contact distance (L2), which is the distance between contact by both ends thereof to the inside of the container (30). By applying an extension/contraction force to both ends of each of the lateral-section packing members (20) in the container (30), the lateral-section packing members (20) deform toward the respective lateral surface (Ps) of the item to be packed (P), causing the item to be packed (P) to be sandwiched from both lateral surfaces (Ps) thereof by the pair of long lateral-section packing members (20).

Description

  The present invention relates to a packing material for packing an object to be packed, and particularly to a packing material capable of suitably packing the object to be packed in a container.

  Conventionally, an object to be packed is sometimes stored in a container such as a frame or a casing, and is conveyed as a package. At the time of transportation, the package is subjected to vibrations and the like, and it is not preferable that the packaged item be displaced in the container at this time. Therefore, when the packaged item is stored in the container, the packaged item is generally stored in the container in a state where the packaged item is packed with a packing material.

  As such a packing material, for example, a packing material including a bottom packing member (support frame) for packing the bottom of an object to be packed such as an engine for an automobile and an upper packing member for packing the upper part of the object to be packed. It has been proposed (for example, Patent Document 1).

  Here, the upper packing material is a packing member in which the pressing block is adhered and fixed to the back surface of the top pad, and the object to be packed is pressed by the top pad through the pressing block in the container. It is fixed in the vertical direction inside.

Japanese Utility Model Publication No. 5-89290

  Thus, as in Patent Document 1, the object to be packed can be fixed in the container by pressing the upper part with the upper packing material, but depending on the object to be packed, the upper part may be There is an object to be packed that is damaged by the pressing force.

  In the case of such an object to be packed, it is difficult to arrange the packing member on the upper part of the object to be packed, and the object to be packed cannot be fixed in the vertical direction in the container. As a result, when the container vibrates in the vertical direction during conveyance, the packaged item is not fixed in that direction, and accordingly, the packaged item may also vibrate (move) in the vertical direction. . Due to this vibration, the object to be packed may be displaced, and in some cases, the upper part may be damaged.

  The present invention has been made in view of the above points, and its purpose is to restrain the vertical movement of the packed object even if the upper part of the packed object is not pressed by the packing member. It is to provide a packaging material that can be.

  In view of the above-mentioned problems, the inventor has intensively studied and, if the upper part of the packed object cannot be pressed, presses the side of the packed object with the packing member, and the friction between the packed object and the packing member. We thought that the vertical movement of the packaged goods could be restricted by the force.

  In this case, for example, in the space formed between the wall surface of the container and the side surface of the packed object in a state in which the packaged object is accommodated, the distance between the wall surface of the container and the side surface of the packed object facing the container Although it is possible to restrain the packaged item in the vertical direction by pressing the side with a large packaged item, it is necessary to arrange a packaging member of an appropriate size at an appropriate position with respect to the packaged item. The present inventors considered that excessive compressive force may act on the side surface of the object to be packed.

  In view of such points, the packing material according to the present invention is a packing material used together with a bottom packing member that packs the bottom of an object to be packed stored in a container, and the packing material is A pair of elongate side packing members that are arranged in a horizontal direction along the side surface of the package and whose both ends are in contact with the container are provided. In the container, the side packing is formed on both side surfaces of the object to be packed packed by the bottom packing member in the container. In a state where the members are arranged, by applying a compressive force to both ends of each of the side packing members, the side packing members are deformed toward the side surfaces of the respective objects to be packed, thereby Long side packaging A member, characterized in that for clamping the object to be packed from the sides.

  According to the present invention, the article to be packed is stored in the container in a state where the bottom part of the article to be packed is packed in the bottom packing member. And an elongate side part packaging member is arrange | positioned facing the width direction of the side surface of a to-be-packaged item. Since the length in the longitudinal direction of the side packing member is formed so as to be longer than the distance between the contacts where both ends are in contact, the tightening force (compression force generated by the container contact) during assembly of the container The side packing member is deformed toward the opposite side surface of the object to be packed.

  As a result, the packing object is pressed from the side surfaces on both sides of the packing object while the pair of side packing members are fixed in the container, and the packing object is sandwiched from both sides by the pair of side packing members. It becomes the state. Due to the pressing force of the side packing member, a frictional force is generated between the article to be packed and the side packing member. In this way, the object to be packed can be restrained in the vertical direction without pressing the upper part of the object to be packed.

  As a more preferable aspect, the distance between the contacts is a distance between the inner walls in the width direction of the container. According to this aspect, the side packing member is disposed using the corner inner wall of the container, and the side packing member is longer than the length (distance) between the inner walls in the width direction of the container. The side packing member can be deformed toward the side surface of the object to be packed by the tightening force in the width direction when the container is assembled (compression force between the inner walls in the width direction of the container).

  Furthermore, as a more preferable aspect of such a pair of side part packing members, the said side part packing member consists of a some division | segmentation material divided | segmented in the longitudinal direction. According to this aspect, since the side packing member is composed of a plurality of divided materials in the longitudinal direction, the side packing member faces the side surface of the packaged object in the vicinity of the adjacent divided material. And bend easily.

  As a result, it is possible to more suitably press the packed object from the side surfaces on both sides of the packed object with the pair of side packing members. Thereby, a to-be-packaged object can be restrained to an up-down direction, without pressing the upper part of a to-be-packaged object.

  As a more preferable aspect of the divided material, a fitting convex portion and a fitting concave portion for fitting the divided materials to each other are formed at least at the side end portions of the adjacent divided materials. According to this aspect, since the fitting convex part and the fitting concave part for fitting the divided members to each other are formed, the long side packing member is integrated with the side surface of the article to be packed. It can arrange | position facing along the width direction.

  Further, since the fitting convex portion and the fitting concave portion are formed at least at the side end portions of the divided members, the side packing member faces the side surface of the packaged object in the vicinity of the adjacent divided member. Easy to bend. Thereby, a to-be-packaged object can be easily pressed with a pair of side part packing member from the side surface of the both sides of a to-be-packaged object.

  As a still more preferable aspect of the side packing member, the side packing member is made of foamed resin. According to this aspect, the side packing member is made of foamed resin, so that when the compressive force is applied to both ends thereof, the side packing member is easily deformed toward the side surfaces of the respective items to be packed. In addition, the side surface of the article to be packed can be protected by the side packing member.

  According to the packing material which concerns on this invention, even if it does not press the upper part of a to-be-packaged object with a packaging member, the movement of the to-be-packaged object to the up-down direction can be restrained.

  As shown in FIG. 1, the to-be-packaged product P according to this embodiment is a to-be-packaged product in which the center of the upper part Pt protrudes. Such an article P to be packed is packed by the packing material 1 including the bottom packing member 10 and the pair of side packing members 20 and 20 and accommodated in the container 30 shown in FIG. (See FIG. 3).

  Here, the bottom packing member 10 and the pair of side packing members 20 and 20 constituting the packing material 1 can be made of any foamed molded body, but are preferably a foamed molded body of a thermoplastic resin. Thermoplastic resins include polystyrene resins, polyolefin resins (eg, polypropylene resins, polyethylene resins), polyester resins (eg, polyethylene terephthalate resins, polybutylene terephthalate resins, or polyethylene naphthalate resins), polycarbonates Resin, polylactic acid resin and the like. Among these, it is preferable to use a composite resin containing polystyrene and polyethylene.

  In the case of a polystyrene resin (EPS resin), the expansion ratio is preferably 30 to 50 times. In the case of a composite resin containing styrene and polyethylene, or a polyolefin resin (PO resin), the expansion ratio is 20 to 50 times. Preferably there is.

  As shown in FIG. 1, the bottom packing member 10 has a storage recess 11 for storing the bottom Pb of the article P to be packed. The depth of the storage recess 11 is such a depth that the side surface Ps of the article to be packed P can be pressed by a pair of side packing members 20 and 20 described later.

  Moreover, in this embodiment, the outer dimension of the bottom packing member 10 is substantially the same size as the bottom 31 of the container 30 described later. However, as will be described later, in the present embodiment, the packaged item P is pressed by the pair of side packing members 20 and 20 and is restrained not only in the vertical direction but also in the width direction by the frictional force. The packaging member 10 need not be the same size as the bottom 31 of the container 30.

  As shown in FIG. 2, the container 30 is a frame composed of a plurality of channels. As for the bottom part 31 of the container 30, support channels 33b and 33b for supporting the bottom part Pb of the article to be packed P are arranged on the bottom channel 33a joined in a square shape.

  The four side portions 32, 32,... Of the container 30 are a pair of corner channels 33c, 33c that form a container (corner portion) of the container 30 and upper channels that connect the corner channels 33c, 33c at the upper portion. 33d. Further, a first reinforcing channel 33e is provided in the vertical direction at the center of the side portion 32 in the longitudinal direction, and connects the lower end of the first reinforcing channel 33e and the upper end of the corner channel 33c. As described above, the second reinforcing channel 33f is provided.

  Further, each side portion 32 of the container 30 is pivotally attached to the bottom portion 31 so as to rotate in the vertical direction with respect to the bottom portion 31, and each side portion 32 is a fastening member such as a screw at the time of packing. Connected by

  In the present embodiment, a frame composed of such a plurality of channels is used as a container. However, for example, a casing composed of a plurality of panels may be used instead of a plurality of channels. .

  Each side packing member 20 is a long member having flexibility, and is disposed so as to face the horizontal direction along the width direction of both side faces Ps and Ps of the article to be packed P at the time of packing. The both ends are in contact with the inside of the container 30 and are members for pressing each side surface Ps of the packaged object P. The side packing member 20 has a horizontal length of a cross section perpendicular to the longitudinal direction that is shorter than the vertical length so that the side packing member 20 is more flexible in the horizontal direction than the vertical direction.

  As shown in FIG. 3, each side packing member 20 is formed so that the length thereof is longer than the inter-contact distance L <b> 2 where both ends thereof are in contact in the container 30. More specifically, the inter-contact distance L <b> 2 is a distance between the inner walls in the width direction of the container 30.

  Here, the distance L2 between the contacts is the distance between the inner walls in the width direction of the container 30. However, for example, the side packing member 20 may be deformed as follows to press the article to be packed P. For example, both ends of the side packing member may be brought into contact with the side inner wall of the container 30 and the length of the side packing member may be made longer than the distance between the contacted side inner walls.

  As shown in FIG. 3, in the side packing member 20, the side packing members 20 are arranged on both side surfaces Ps and Ps of the article P to be packed packed by the bottom packing member 10 in the container 30. In such a state, by applying a compressive force to both ends of each side packing member 20, the side packing member 20 is deformed toward the side surface Ps of each packaged item P, whereby a pair of elongated shapes are formed. The side packing member 20 has such a length that the object to be packed P is sandwiched from both side faces Ps and Ps.

  By comprising in this way, the to-be-packaged goods P are packed in the state as shown in FIG. 3 using the packing material 1 which concerns on this embodiment. Specifically, first, the article P to be packed is placed on the bottom 31 of the container 30 in a state where the bottom Pb of the article P is packed on the bottom packing member 10, and this is stored in the container 30. At this time, the side part 32 of each container 30 is in an open state.

  The long side packing member 20 is disposed so as to be opposed along the width direction of the side surface Ps of the article to be packed P, and the side portions 32 of the container 30 are closed, and these are connected by a fastening member. At this time, the length L1 in the longitudinal direction of the side packing member 20 is longer than the length (distance) L2 between the inner walls 35 and 35 in the width direction of the container 30, so as shown in FIG. A tightening force in the width direction (compression force between inner walls in the width direction of the container) F1 acts when the container 30 is assembled. Due to this compressive force F1, the first and second reinforcing channels 33e and 33f exist outside the side packing member 20, so that the side packing member 20 is covered by the side packing member 20 of the container 30. It is deformed (bent) toward the side surface Ps of the package P.

  As a result, the pair of side packing members 20, 20 are pressed from the side surfaces Ps on both sides of the package P in a state where the package P is fixed in the container 30. It will be in the state clamped by the packaging members 20 and 20. Due to the pressing force F <b> 2 of the side packing members 20, 20, a frictional force is generated between the article P to be packed and the side packing members 20, 20. In this way, the object to be packed P can be restrained in the vertical direction using the pair of side packing members 20 and 20 without pressing the upper part Pt of the object to be packed P.

  Furthermore, the side packing member 20 is made of foamed resin, so that when the compressive force is applied to both ends thereof, the side packing member 20 is easily deformed toward the side surface Ps of each packaged item P. And the side surface Ps of the article to be packed P can be protected by the side packing member 20.

  Fig.5 (a) is a typical perspective view of the side part packaging member which concerns on another aspect, (b) is sectional drawing equivalent to FIG. 4 when the side part packaging member of (a) is used. is there. As shown in FIG. 5, in this aspect, the side packing member 20 </ b> A is composed of a plurality of divided members 22, 22 that are divided into two in the longitudinal direction. In addition, since the other structure is the same as the structure mentioned above, the same code | symbol is attached | subjected and the detailed description is abbreviate | omitted.

  The packaged item P is packed in the container 30 using a side packing member 20A composed of two divided members 22 and 22 as shown in FIG. The side packing member 20 </ b> A is disposed facing the width direction of the side surface Ps of the article to be packed P in a state where the ends of the divided members 22 and 22 are in contact with each other.

  This arrangement state is maintained, each side 32 of the container 30 is closed, and these are connected by a fastening member. At this time, since the total length in the longitudinal direction in a state where the divided members 22 and 22 are in contact with each other is longer than the length between the inner walls 35 and 35 in the width direction of the container 30, similarly to the case described above. As shown in FIG. 5B, a tightening force in the width direction (compression force between inner walls in the width direction of the container) F1 acts when the container 30 is assembled.

  In this aspect, since the side packing member 20 is composed of a plurality of divided members 22 and 22 divided in the longitudinal direction, the side packing member 20A is packed in the vicinity of the contact portion between the divided members 22 and 22. It becomes easier to bend toward the side surface Ps of the object P, and the dividing member 22 presses the side surface Ps (see the pressing force F2 in FIG. 5B). In this manner, as in the case described above, the object to be packed P can be restrained in the vertical direction using the pair of side packing members 20A and 20A without pressing the upper part Pt of the object to be packed P. it can.

  Here, in the case of the side packing member shown in FIG. 5B, the divided materials 22 and 22 must be accommodated in the container 30 in contact with each other. Both sides 32 of the container 30 must be closed with both of these being held. Then, you may use the side part packaging member shown to Fig.6 (a)-(c). 6A to 6C are schematic perspective views of a side packing member according to another aspect.

  As shown in FIG. 6A, the side packing member 20B is composed of divided materials 22A and 22B divided at the center in the longitudinal direction, and divided into side end portions 22a and 22b between the divided materials 22A and 22B. A fitting convex portion 22c and a fitting concave portion 22d for fitting the materials 22A and 22B to each other are formed. The fitting convex portion 22c is formed along the width direction (horizontal direction at the time of arrangement) of the end surface 22e of the divided member 22A, and the fitting concave portion 22d is formed in the width direction (at the time of arrangement) of the end surface 22f of the divided material 22B. (Horizontal direction).

  According to this aspect, since the fitting convex portion 22c and the fitting concave portion 22d are formed so that the divided members 22A and 22B are fitted to each other, the long side portion is formed by fitting them. The packing member 20 </ b> B can be easily disposed integrally and facing along the width direction of the side surface of the object to be packed.

  Furthermore, since the fitting convex portion 22c and the fitting concave portion 22d are formed at least at the side end portions 22a and 22b of the divided members, in the vicinity of the fitting portion between the divided members 22A and 22B, the side packing member 20B. Is easy to bend toward the side surface Ps of the article to be packed P, as shown in FIG. Thereby, the to-be-packaged object P can be easily pressed by the pair of side-part packing members 20 from the side surfaces Ps on both sides of the to-be-packaged object P.

  Moreover, the side part packing member 20C shown in FIG.6 (b) may be sufficient. Specifically, the dividing member 20A of the side packing member 20C forms the fitting convex portion 22g in a part along the width direction (horizontal direction at the time of arrangement) of the end surface 22e of the dividing material 22A. 20B forms the fitting recessed part 22h fitted to the fitting convex part 22g in the part along the width direction (horizontal direction at the time of arrangement | positioning) of the end surface 22f of the division | segmentation material 22B.

  Moreover, as shown in FIG.6 (c), side part packing member 20D may be sufficient. Specifically, the dividing member 20A of the side packaging member 20D has a protruding length that is different from the fitting convex portion 22j along the width direction (horizontal direction when arranged) of the end surface 22e of the dividing material 22A. The dividing member 20B is formed so that the fitting recess 22k fitted to the fitting projection 22j has a different depth of depression along the width direction of the end surface 22f of the dividing material 22B (horizontal direction when arranged). You may form in.

  The embodiments of the present invention have been described in detail above, but the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention described in the claims of the registered utility model.
