FIG. 1 is a configuration diagram showing the configuration of a packing material according to an embodiment of the present invention. FIG. 2 is a perspective view of a packing material according to one embodiment of the present invention and a diagram for explaining the operation of a projection.

First, a description will be given with reference to FIG. A cushioning material 2 made of a low-foaming styrene foam or the like is attached to the product 1 on the left, right, front and rear. The packing auxiliary sheet 4 is attached so as to sandwich both sides of the two cushioning materials 2 attached to the product 1.

The packing auxiliary sheet 4 has a guide concave portion 2 which is a concave groove provided on a lower portion or a side surface of the cushion material 2.
b and the convex protrusion 2a, the cushion material 2
It is a structure that is hard to be displaced. In FIG. 1, the guide recess 2 b is formed in a concave shape on the side surface of the cushion material 2. That is, the width dimension W of the packing auxiliary sheet 4 is made smaller than the dimension W ′ of the concave section of the cushion material 2 so that the packing auxiliary sheet 4 enters the concave section of the cushion material 2, and the packing auxiliary sheet 4 is The material 2 is not shifted.

Further, a convex protrusion 2a is provided on the side surface of the cushion material 2, and the guide hole 4e formed in the packing auxiliary sheet 4 is fitted into the protrusion 2a so as not to shift. ing.

The product 1 is stored in the carton case 3 with the packing auxiliary sheet 4 sandwiched between both sides of the cushion material 2. When storing and packing the product, it is possible to easily pack the product by inserting a hand into the handle portions 4a provided at both ends of the packing auxiliary sheet 4 to lift the product and storing the product in the carton case 3. The packed state after storage is as shown in the perspective view of FIG.

For the carton case of the present embodiment, a cardboard material having excellent cushioning properties is usually used. Carton case 3
Are provided with handle portions 3a on two opposite sides so that the packed carton case can be easily lifted and moved. Handle part 3
The upper end of “a” has a bent portion which is connected to a cardboard material which is a material of the carton case 3 of the handle cutout portion.

Next, when unpacking the product, two handle portions 3 for transporting the carton case in which the product is packed are used.
Insert your hand into a and lift it up and move it to an appropriate place. The product 1 can be easily taken out of the carton case 3 by opening the upper surface of the carton case, inserting a hand into the handle portion 4a of the packing auxiliary sheet 4, and lifting the product upward.

Even if the height including the product and the cushioning material is larger than the length of the human forearm, it is easy to insert the hand into the handle 4a and lift the product upward. Further, since the arm can be bent at the elbow of the worker's arm, the muscles of the forearm and the rear arm can be tensed to exert a force, and the unpacking operation can be performed easily and safely.

Here, as shown in FIG. 1, the point M on the packing auxiliary sheet 4 hanging from the middle point connecting the center of the handle 4a of the packing auxiliary sheet 4 is not the center of the product but the center of gravity of the product 1. I adjusted to the position. By adjusting the position of the midpoint M to the position of the center of gravity of the product, the weight of the product is applied to the handle portion 4a when the packing auxiliary sheet is lifted,
The force applied to the packing auxiliary sheet is only in the sheet pulling direction.

If the carton case 3 is provided with the handle 3a, the cardboard material in the notch of the handle may enter the inside of the carton case. When the auxiliary sheet is raised and the product and the cushion material are lifted, The protruding portion 2a of the cushion material 2 corresponds to the front end portion A of the corrugated cardboard material in the cutout portion of the handle. At this time, since there is an inclined portion on the upper surface of the protrusion 2a, as shown in FIG. 2B, the corrugated cardboard material in the cutout portion is pushed up to the upper inside of the carton case by the inclined portion. When the protruding portion 2a further rises upward, as shown in FIG. 2 (c), the inclined portion of the protruding portion 2a is taken out, and the cardboard material bulging inward at the bent portion of the hand portion 3a is pushed outward. Act like so.

If there is an inclined portion on the upper surface of the projecting portion 2a, the product can be lifted smoothly without being caught by the projecting portion of the cushion material and the cardboard material of the handle portion of the carton case by the action of the inclined portion.

FIG. 3 is a diagram showing the shape of the projection of this embodiment. FIG. 3A shows an embodiment in which the upper surface of the protruding portion is linearly inclined. FIG. 3B is an embodiment in which a part of the upper surface of the protrusion has a linear inclination. FIG. 3C shows an embodiment in which the upper surface of the protrusion has an arc-shaped slope. Both shapes operate the same as in the above-described embodiment,
Has the same effect.

FIG. 4 is a view showing the positions of the protrusions of the cushioning material and the handle of the carton case during packing in this embodiment. The upper surface (height H2) of the projection 2a is located below the handle 3a (height H1) of the carton case. Since H2 is smaller than H1, cushion 2
When is taken out upward, the corrugated cardboard material of the handle notch is folded upward by the projection 2 and is not caught by the projection due to the inclination of the upper surface of the projection.

[0022]

According to the present invention, even if the height of the product including the cushioning material is equal to or greater than the length of the human forearm and the weight is about 20 kg,
The product can be easily lifted out of the carton case and installed in the installation place, and the product is prevented from being accidentally dropped and damaged when unpacking.
