Japanese Patent No. 3693641

  By the way, when placing a plurality of luggage on the pallet, after placing one luggage on the pallet, the operator holds the cushioning material on the side of the luggage while holding the cushioning material, In some cases, another package may be placed on the opposite side of one package. The shock-absorbing material is fixed by being sandwiched between the one load and the other load, and the shock-absorbing of the load is prevented by the shock-absorbing material.

  When such an operator holds the cushioning material, the cushioning material is stood on the side of the luggage, and when the other luggage is placed on the opposite side of the one luggage with the cushioning material sandwiched therebetween, Since the outer peripheral portion of the cushioning material is held, there is a possibility that an accident may occur in which a finger or a hand is caught between another baggage and the cushioning material.

  In particular, in the cushioning material disclosed in Patent Document 1, since the concave portion is formed on the front and back main surface side, when the cushioning material is erected on the side surface of the load, an operator inevitably has a cushioning material. Because the fingers are held in the recesses of the cushions (the fingers and hands are positioned between the other load and the cushioning material by placing the fingers in the recesses of the cushioning material), the operator's attention is distracted In such a case, there is a problem that an accident in which a finger or a hand is caught between another load and a cushioning material easily occurs.

  The present invention has been made paying attention to the above points, and in the cushioning material for transportation arranged between a plurality of luggage, the operator can easily and safely arrange and hold between the luggage, It is another object of the present invention to provide a transportation cushioning material that can easily take out the cushioning material even when the cushioning material is sandwiched between packages.

  In order to solve the above-described problems, a transportation cushioning material according to the present invention is a transportation cushioning material in which a resin material is foam-molded into a substantially rectangular flat plate disposed between a plurality of loads loaded on transportation means. A hole that extends inwardly from the side surface and into which an operator's finger or hand can be inserted is formed on at least one side surface of the buffer material that is a surface other than the main surface along the luggage. It is characterized by having.

By configuring in this way, the operator can easily insert the transport cushioning material between the loads and hold the transport cushioning material by putting the hand into the hole of the cushioning member.
In particular, the hole is formed on the side surface of the transport cushioning material, and when the operator holds the transport cushioning material, it is not necessary to grasp the main surface of the transport cushioning material. The conventional problem that the hand is sandwiched between the cushioning material and the luggage can be solved, and the work can be performed safely.

In addition, even if the hole is formed, the front and back main surfaces of the cushioning material are held, and even if a hand (fingertip) is sandwiched between the load and the cushioning material, the hole is formed. Therefore, the main surface of the cushioning material on which the hand (fingertip) is located can be easily deformed compared to other parts, and damage to the hand (fingertip) can be reduced.
Further, even when the transport cushioning material is sandwiched between the packages, the operator can easily pull out the transport cushioning material because the hole into which the operator's finger or hand can be inserted is formed. be able to.

Here, the hole is formed in a groove shape from the upper end side to the lower end side of the side surface, and one or a plurality of pillar members connecting one main surface and the other main surface are in the hole. It is desirable to be provided.
By providing the column member in this way, the strength of the transport cushioning material can be improved and the durability can be provided while exhibiting the effects of the invention.

Further, it is desirable that a finger locking portion is formed by a recess extending toward at least one main surface side in the hole.
By providing the finger locking portion in this way, when the operator puts his / her hand into the hole, the finger locking portion can be hooked, and the transport cushioning material can be carried or the space between the loads can be narrowed. Removal from the held state and holding of the transport cushioning material can be performed more easily.

Moreover, it is desirable that the depth dimension of the hole is 1 cm or more and 20 cm or less.
By defining the depth of such a hole, when the operator puts the hand (fingertip) into the hole, carrying the cushioning material for transportation or taking it out from the state of being held between the luggage, In addition, the transport cushioning material can be held more easily.

When the depth of the hole is less than 1 cm, it is difficult to maintain the cushioning material on the side of the load because the portion where the finger can be inserted is small, and the hole is sandwiched between the load and the load. Also when pulling out the buffer material, it is not preferable because it is difficult to pull it out.
Moreover, when the depth dimension of a hole exceeds 20 cm, the intensity | strength of buffer material itself will be weakened, and it is unpreferable.

  Moreover, the said hole may be provided in the right-and-left both sides of the main surface, and in that case, the operator can use the cushioning material for transport without minding the front-back direction of the cushioning material for transportation.

  According to the present invention, in the cushioning material for transportation arranged between a plurality of packages, the operator can easily and safely arrange and hold between the packages, and the cushioning material is sandwiched between the packages. Even in such a state, the operator can easily extract it.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a cushioning material for transportation according to the present invention will be described with reference to the drawings.
Note that the transport cushioning material of the present invention is used by being inserted between the cargos 51 in the same manner as the conventional cushioning material shown in FIG. 12, and functions to suppress rattling between the cargos. .
FIG. 1 is a perspective view of a transport cushioning material (hereinafter also simply referred to as a cushioning material) according to the present invention. FIG. 2 is a perspective view showing a part (broken line part) cut out from the cushioning material of FIG. FIG. 3 is a plan view showing a state in which a hand (finger) is sandwiched when the cushioning material of FIG. 2 is used.

The cushioning material 1 shown in FIG. 1 is formed by foaming a polyethylene resin material into a plate shape, for example, and may be integrally formed into the shape shown in the figure, or after being formed into a plurality of plate members, The shapes shown in FIG. Further, the cushioning material 1 may have a shape shown in the figure by cutting or cutting.
The material of the buffer material is not limited to the polyethylene resin material, and has a buffering action, for example, polyurethane (PUR) resin material, polystyrene (PS) resin material, polyolefin (Polyethylene (PE) or polypropylene (PP)) resin materials can also be used.

Moreover, the said buffer material 1 is the substantially rectangular flat plate shape which has the main surfaces 1a and 1b and the side surfaces 1c and 1d which follow the said luggage | load, and the external dimensions of the main surfaces 1a and 1b are about 1000 mm-for example in the vertical direction. 1800 mm, the horizontal direction is formed to be about 800 mm to 1500 mm, and the thickness (the width of the side end faces 1c and 1d) is, for example, about 40 mm to 100 mm.
In addition, the above-described external shape and thickness dimension can be appropriately changed according to the application.

Moreover, as shown in FIG. 1, FIG. 2, it extends inward from the said side surface 1c to at least one side surface 1c among the side surfaces which are surfaces other than the main surfaces 1a and 1b along the said load of the cushioning material 1, And the recessed part (hole) 10 in which an operator's finger | toe or hand can be inserted is formed.
The recess (hole) 10 is formed as a linearly continuous groove from one end of the side surface to the other end (vertical direction).

  Specifically, if an example of the dimension of the groove-shaped recess 10 is shown, the width dimension d1 of the groove-shaped recess 10 is, for example, 2 cm to 5 cm as shown in FIG. d2 is preferably set to a value of 1 cm to 20 cm.

Here, when the width dimension d1 of the groove-like recess 10 is less than 2 cm, it is not preferable because a finger or a hand cannot be inserted or is difficult to insert. On the other hand, if the width dimension d1 of the groove-like recess 10 exceeds 5 cm, the thickness of the cushioning material becomes unnecessarily thick, which is not preferable.
In addition, when the depth d2 from the side surface of the groove-like recess 10 is less than 1 cm, since the portion into which the finger can be inserted is small, a finger is put into the recess 10 and a cushioning material is placed on the side of the luggage. This is not preferable because it is difficult to maintain the standing state and it is difficult to pull out the cushioning material sandwiched between the loads. In addition, even when the recess 10 is formed, when the front and back main surfaces of the cushioning material are held and the hand is sandwiched between the load and the cushioning material, the depth dimension d2 is less than 1 cm. In this case, the deformation area of the main surface of the cushioning material is small, and the effect of reducing damage to the hand is small, which is not preferable.
On the other hand, when the depth dimension d2 from the side surface exceeds 20 cm, the deformation area of the main surface of the cushioning material is large and the effect of reducing damage to the hand is great, but the strength of the cushioning material itself is weakened. It is not preferable. In addition, when the external dimensions of the cushioning material itself are large, the recess 10 exceeding 20 cm may be formed.

According to the cushioning material 1 formed as described above, the operator can put his / her hand into the recess 10, so that the insertion (arrangement) of the cushioning material 1 between the loads and the holding of the cushioning material 1 are easy. It can be carried out.
In particular, the concave portion 10 is formed on the side surface 1c of the cushioning material 1, and when the operator holds the cushioning material 1, the operator does not grasp the main surfaces 1a and 1b on the front and back of the cushioning material 1 (the operator Since the hand (fingertip) can be placed in the recess 10 to hold the cushioning material), the main surface of the cushioning material can be set up along the side of one load.
As a result, it is possible to prevent an accident in which a finger or a hand is caught between another baggage and the cushioning material when the other baggage is placed on the opposite side of the one baggage with the cushioning material sandwiched therebetween. .

Also, as shown in FIG. 3, the main surfaces 1a and 1b of the front and back surfaces of the cushioning material 1 are held in spite of the formation of the recess 10, and a finger is placed between the other luggage and the cushioning material. Alternatively, even if the hand F is sandwiched, since the concave portion 10 is formed, the front and back main surfaces 1a and 1b of the cushioning material 1 where the finger or hand is positioned are deformed to reduce damage to the finger or hand. Can do.
Particularly, since the thickness of the cushioning material in the portion where the recess 10 is formed is thinner than other portions, the portion of the recess 10 can be easily deformed, and the damage to the finger or hand can be reduced. .

Moreover, the said recessed part (hole) 10 does not need to be a linear continuous groove | channel from the one end part of the said side surface toward the other end part (vertical direction), and is like the 1st modification shown in FIG. Alternatively, it may be a recess (hole) 10 having a circular cross-sectional shape into which a finger can be inserted. FIG. 4 is a perspective view showing a part cut out from the transport cushioning material for explanation, and is enlarged, and corresponds to FIG. 2.
Specifically, if an example of the dimension of the recess (hole) 10 is shown, the diameter of the recess (hole) 10 is 2 cm to 5 cm, and the depth dimension from the side surface is 1 cm to 20 cm. Is preferred.

  Moreover, the rectangular recessed part 10 may be sufficient like the 2nd modification shown in FIG. Specifically, if an example of the dimension of the recess 10 is shown, the width of the recess 10 is 2 cm to 5 cm and the depth from the side surface is 1 cm to 20 cm, for example, as in the case shown in FIG. The dimension in the vertical direction is preferably 2 cm or more. FIG. 5 is a perspective view showing a part of the transport cushioning material, which is cut out for explanation, and enlarged, and corresponds to FIG.

  Moreover, the dimension of the said recessed part 10 in an above-described embodiment and a 1st, 2nd modification is not limited to the said dimension, It has a shape dimension which can insert a finger or a hand, Any shape and dimension can be used as long as a finger or a hand is put into the recess 10 and a cushioning material is maintained on the side of the luggage.

Further, as in the third modification shown in FIG. 6, a finger locking portion 10 a made of a dent extending on the one main surface 1 a side of the cushioning material 1 is formed in the deepest portion of the concave portion 10. It is preferable. A step portion is formed on the main surface 1a side by the recess, and a finger is locked to the step portion. FIG. 6 is a perspective view showing a part of the transport cushioning material cut out for explanation and enlarged, and corresponds to FIG.
By providing the finger locking portion 10a in this manner, the operator can put the hand into the groove-shaped recess 10 and further hang the finger on the finger locking portion 10a, so that the cushioning material can be reliably held. it can. Also, when pulling out the cushioning material sandwiched between the luggage, the cushioning material can be pulled out more easily by placing a finger on the finger locking portion 10a.

The width dimension d3 of the finger locking part 10a is preferably 1 cm to 3 cm, and the depth dimension d4 of the finger locking part 10a is preferably 0.5 cm to 2 cm.
Here, when the width dimension d3 of the finger locking part 10a is less than 1 cm, the finger is poorly applied. When the width dimension d3 of the finger locking part 10a exceeds 3 cm, the finger locking part Since 10a becomes larger than necessary and the strength of the cushioning material is weakened, it is not preferable.
Further, when the depth dimension d4 of the finger locking part 10a is less than 0.5 cm, the finger is not easily hooked, and the cushioning material can be easily buffered when the cushioning material sandwiched between the luggage is pulled out. The material cannot be pulled out.
Moreover, when the depth dimension d4 of the said finger | toe latching | locking part 10a exceeds 2 cm, since the thickness of a buffer material becomes thick more than necessary, it is unpreferable.
The dimension of the finger locking part 10a is not limited to the above dimension, but is a dimension that allows the operator to put his / her hand into the groove-shaped recess 10 and to hang the finger on the finger locking part 10a. I just need it.

  According to the cushioning material 1 as in the third modified example, the same effect as the cushioning material 1 in the above-described embodiment and the first and second modified examples can be obtained, and further sandwiched between the cargo. When pulling out the cushioning material, the cushioning material can be pulled out more easily by hooking a finger on the finger locking portion 10a.

In addition, in the said embodiment, although the finger | toe latching | locking part 10a dented only in the one main surface 1a side of the shock absorbing material 1 was formed in the recessed part 10 of the shock absorbing material 1, it is for transportation which concerns on this invention. The buffer material is not limited to the configuration.
That is, although not shown, a finger locking portion that is recessed only toward the other main surface 1b side of the cushioning material 1 may be formed, or FIG. 8 (a perspective view corresponding to FIG. 6), FIG. As in a fourth modification shown in FIG. 7, a finger locking portion 10 a that is recessed on one main surface 1 a side and a finger locking portion 10 b that is recessed on the other main surface 1 b side of the cushioning material 1. It is good also as a structure which formed both.
By configuring as shown in FIG. 8 and FIG. 9, regardless of the dominant hand used by the worker, the operator's finger can be hung on one of the finger locking portions 10a and 10b, and the cushioning material 1 Can be easily held. Further, even when the cushioning material 1 is turned upside down, the operator's finger can be hung on one of the finger locking portions 10a and 10b, and the cushioning material 1 can be easily held.

Moreover, in the said embodiment, although demonstrated as what forms the groove-shaped recessed part 10 only in one side end surface 1c of the buffer material 1, like the 5th modification shown in FIG. 10, the main surface 1a It is good also as a structure which forms the recessed part 10 in the side end surfaces 1c and 1d of the both right and left sides of 1b, respectively.
In the example shown in FIG. 10, a finger locking portion 10 a that is recessed on the main surface 1 a side is provided in the recess 10 formed on one side end surface 1 c, and in the recess 10 that is formed on the other side end surface 1 d, Although the finger locking portion 10b that is recessed on the main surface 1b side is provided, the direction in which the finger locking portion provided in each recess 10 is recessed is not limited to this example, and either side of the main surface 1a, 1b, Or both the main surfaces 1a and 1b may be sufficient.
As described above, the concave portions 10 are formed on the left and right side end surfaces 1c and 1d of the main surfaces 1a and 1b of the cushioning material 1, so that the operator does not mind the front-rear direction of the cushioning material 1 and the cushioning material 1 is used. Can be used.

In addition, in the cushioning material for transportation according to the present invention, in addition to the configuration shown in FIGS. 1 to 10, the main surface 1a is formed in the recess 10 as shown in FIG. 11 (perspective view corresponding to FIG. 2). A plurality of pillar members 2 that connect the side and the main surface 1b side may be arranged at predetermined intervals along the longitudinal direction of the recess 10.
That is, by providing the column member 2 in this way, the strength of the cushioning material 1 can be improved and durability can be provided.

When the cushioning material 1 shown in FIG. 11 is manufactured, the main surfaces 1a and 1b and the column member 2 are separately molded, and the contact surfaces M1, the main surface 1b and the column members of the molded main surfaces 1a and 1b are formed. The two contact surfaces M2, the main surface 1a, and the contact surface M3 of the column member 2 may be integrated by bonding with an adhesive.
The main surfaces 1a and 1b and the column member 2 may be formed separately by cutting or cutting. Moreover, in addition to using the adhesive, it may be integrated by heat welding.
