  However, in the case of an article to be packed as in Patent Document 1, since the shape of the article to be packed is a substantially rectangular parallelepiped shape, and the upper surface is flat, it is easy to bind the object to be packed together with the bottom packing member by a binding band. For example, when packing an object having a complicated shape such as a transmission or an engine, it is difficult to stably pack the object to be packed with a binding band.

  In such a case, for example, an upper packing member corresponding to the shape of the upper part of the object to be packed is arranged on the object to be packed, and the object to be packed is sandwiched in the vertical direction between the upper packing member and the bottom packing member. It is also conceivable to pack an article to be packed. However, when such an upper packing member is provided, the size of the packing body in the upward direction is increased.

  The present invention has been made in view of the above points, and the object of the present invention is to limit the movement of an object to be packed in a vertical direction in a more compact packing state without using a binding band or the like. It is to provide a packaging material that can be used.

  In order to solve the above-mentioned problem, the packing material according to the present invention is a packing material for packing an object to be packed having a protruding portion formed on a side surface, and the packing material accommodates the bottom of the object to be packed. A bottom packing member in which a recess is formed, and a holding member that is attached to the bottom packing member and holds the packed object at a position facing the side surface of the packed object. When the holding member is attached to the bottom packaging member in a state where the packaged object is accommodated in the accommodation recess of the bottom packaging member, the packaging is performed so as to cover at least a part above the protruding portion. It is characterized in that a restricting portion for restricting the upward movement of the object is formed.

  According to the present invention, when the holding member is attached to the bottom packing member in a state where the bottom portion of the article to be packed is received in the receiving recess of the bottom packing member, the limiting portion formed on the holding member is Cover at least part of the upper part of the protrusion. As a result, even if an impact load is applied in the vertical direction to the packed article to be packaged, the upward movement of the article to be packaged with respect to the bottom packaging member is restricted by the restriction unit. As a result, it is possible to limit the movement of the article to be packed with respect to the bottom packing member without using a binding band.

  As a more preferable aspect, the packaged object includes a side surface on which the protruding portion is formed and a side surface formed so as to sandwich a corner portion of the packaged object together with the side surface on which the protruding portion is formed. It has at least two side surfaces, and the holding member is formed so as to extend along each side surface of the two side surfaces sandwiching the corner portion from the corner portion of the packaged object. . According to this aspect, when the holding member is attached to the bottom packaging member in a state where the bottom portion of the packaged object is accommodated in the accommodation recess of the bottom packaging member, the corner is sandwiched from the corner of the packaged object 2 A holding member will extend along one side.

  As a result, the object to be packed can be held at a position facing each of the two side surfaces sandwiching the corner of the object to be packed with one member, and the holding member is connected to the bottom packing member in a wide range. You can also As a result, even if an upward load is applied to the restricted portion due to an impact or the like in a state in which the article to be packed is packed with the packing material, the holding member can be prevented from being detached from the bottom packing member. And a stable packing state can be maintained.

  As a more preferable aspect, the holding member includes a pair of divided holding members that are fitted to each other so as to be split, and the holding member is divided into the pair of divided holding members in a state of the bottom packing member. It is divided at a position where it can be accommodated in the accommodating recess.

  According to this aspect, the pair of split holding members constituting the holding member are fitted to each other so that they can be divided. The object to be packed can be held at the facing position. On the other hand, when unpacking the object to be packed from the packing material, the holding member attached to the bottom packing member is removed, and the divided holding members fitted to each other are separated (divided). Since the pair of divided holding members can be accommodated in the accommodating recesses of the bottom packaging member, the packaging material after unpacking can be stored and transported without being bulky.

  Furthermore, as a preferable aspect, each of the divided holding members can be attached to the bottom packing member, and the restriction portion is formed on at least one divided holding member of the divided holding members, and the one divided piece is formed. The holding member is fitted to the other divided holding member so as to press the other divided holding member from above.

  According to this aspect, if an excessive load is applied to the limiting portion of one split holding member from the protruding portion of the packed object, even if one split holding member is detached from the bottom packing member, the other The split holding member is held by the bottom packing member (it remains attached), and the other split holding member secures the function of holding the packed object at a position facing the side surface of the packed object. be able to.

  According to the present invention, it is possible to limit the movement of the packed object in the vertical direction without using a binding band.
