Therefore, a cushioning material having a configuration that is easy for an operator to hold in terms of work efficiency is desired.

  In view of the above, the present invention provides a cushioning material that improves cushioning properties and is easy to grip for an operator.

  In order to solve the above problems, a cushioning material according to the present invention is a cushioning material inserted between packages to be transported, and includes a flat plate made of a foamed plastic material and one of the flat plates in contact with the cargo. A plurality of first recesses formed at the center of the side surface of the plate and a plurality of first recesses formed at positions that do not overlap the first recess at the center of the other side of the flat plate that contacts the luggage. 2 recesses and an outer peripheral edge surrounding the central portion of the flat plate, regardless of the thickness of the central portion, a constant thickness dimension and a constant depth from the end of the outer peripheral edge toward the central portion And a grip portion having dimensions.

  At this time, the gripping portion is provided over the entire circumference of the outer peripheral edge. And the groove was formed over the perimeter of the boundary part of the said holding part and the said center part in the one side surface or both side surface of the said flat plate, It is characterized by the above-mentioned.

  Further, the grip portion is provided in a part of the outer peripheral edge. And the groove | channel was formed in the boundary part of the said holding | grip part and the center part of the one side surface or both side surface of the said flat plate, It is characterized by the above-mentioned.

  The cushioning material according to the present invention is provided with a plurality of recesses on both sides of the flat plate, and the recesses on both sides are formed at positions that do not overlap each other, thereby improving the cushioning property while ensuring strength. I am letting. Therefore, a cushioning material with improved adhesion to the load and shock absorption is provided. Moreover, by forming the recesses in the flat plate, the weight can be reduced correspondingly, and the raw materials can be reduced, resulting in an inexpensive cushioning material.

  A gripping portion having a constant thickness dimension and a constant depth dimension from the end of the outer peripheral edge toward the central part regardless of the thickness dimension of the central part of the flat plate is provided on the outer peripheral edge surrounding the central part. As a result, the cushioning material can be easily grasped by the operator during work and the strength of the gripping portion is sufficiently secured.

It is a figure which shows one Embodiment of the shock absorbing material which concerns on this invention from a both-sides surface and an AA 'cross section. It is a figure which shows another embodiment of the shock absorbing material which concerns on this invention from both sides | surfaces and an AA 'cross section. It is explanatory drawing of the modification of the holding part of the shock absorbing material which concerns on this invention. It is explanatory drawing about use of a shock absorbing material.

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

  FIG. 1 shows a first embodiment of the present invention. In FIG. 1, the buffer material 1 is a phenol resin (PF) including polystyrene (PS), polyurethane (PUR), polyolefin (mainly polyethylene (PE) or polypropylene (PP)) foamed with fine bubbles. ), Polyvinyl chloride (PVC), urea resin (UF), silicone (SI), polyimide (PI), melamine resin (MF), etc. It consists of the flat plate 2 made of foamed plastic. As the foamed plastic, polystyrene foam made of polystyrene is lightweight, extremely easy to mold and cut, and has excellent elasticity and shock absorption and is suitable for the cushioning material 1.

  1A shows a left side surface of the flat plate 2, FIG. 1B shows a AA ′ cross section of the flat plate 2, and FIG. 1C shows a right side surface of the flat plate 2. For example, the outer dimensions of the flat plate 2 are 80 cm in length and 120 cm in width, and the thickness is 5 cm in the central portion 5 and 4 cm in the outer peripheral portion surrounding the central portion 5. The outer peripheral edge is a portion having a depth dimension from the outer peripheral end portion toward the central portion 5 and is provided with an interval of, for example, 5 cm, and a grip portion 4 that will be apparent later is formed in this portion.

  On the surface of the central portion 5 on one side surface of the flat plate 2, a plurality of concave portions 3A are provided at predetermined intervals in the vertical and horizontal directions. Similarly, a plurality of recesses 3B are also provided on the surface of the central portion 5 on the other side surface of the flat plate 2 at predetermined intervals in the vertical and horizontal directions. In the figure, the shape of the recesses 3A and 3B is shown as a cylindrical shape, but is not limited to this, and may be a cylinder such as a triangle, a square, a polygon or a star, and the shape of the recess is also a cylinder. Alternatively, it may be curved. Further, the shapes may be different from each other.

  The recesses 3A and the recesses 3B are alternately provided in a zigzag shape, and are formed at positions that do not overlap each other from the front. Further, the depth dimension of the recesses of each recess 3A and each recess 3B is set to be less than t (less than 2.5 cm in this example), which is 1/2 the thickness dimension of the central portion 5.

  Thereby, the shock absorbing material 1 received the load of the luggage | load from the side surface direction by providing several recessed part 3A and the recessed part 3B in the both sides | surfaces of the flat plate 2, and making the thickness dimension of the flat plate 2 small in the recessed part. At this time, the cushioning property is enhanced because the material is contracted greatly compared to the cushioning material not provided with the recesses 3A and 3B, and the adhesion to the load and the shock absorbing property are improved. And since cushioning properties are good, even when the cushioning material 1 is inserted when the interval between loads is narrow, it can be pushed in easily.

  The buffer material 1 is provided with the recesses 3A and 3B to reduce the thickness of the flat plate 2 at the recesses, but the recesses 3A and 3B are opposed to each other from the front and do not overlap each other. Therefore, the cushioning property can be improved while ensuring the strength. In addition, by providing a plurality of recesses 3A and recesses 3B on both side surfaces of the flat plate 2, it is possible to reduce the cost by reducing the weight of the buffer material 1 and reducing the raw materials.

  The outer peripheral edge of the flat plate 2 is a portion formed at an interval of 5 cm in depth from the end of the outer periphery to the central portion 5 as described above, and the thickness dimension is the central portion 5 on the side surface of the flat plate 2. Regardless of the thickness dimension, it is always fixed to a constant thickness dimension, for example, 4 cm. In this embodiment, the part covering the whole outer peripheral edge of the flat plate 2 constitutes the grip portion 4 as it is. And the holding | grip part 4 is being fixed to the space | interval of the above-mentioned dimension 5 cm from which the depth dimension to the center part 5 from the edge part of an outer periphery is constant. A size having a depth dimension of 5 cm and a thickness dimension of 4 cm is a dimension that can be easily gripped as the grip portion 4 during the work.

  Although the thickness dimension of the central part 5 of the flat plate 2 has been described as 5 cm, various thicknesses of the central part 5 are prepared and used when inserted between the packages 20 as shown in FIG. Depending on the width dimension of the load 20 and the dimension of the pallet 22, they are properly used. However, even if the dimension of the central part 5 is 5 cm or more, the thickness dimension of the outer peripheral edge as the grip part 4 and the depth dimension to the central part 5 are constant. It is easily fixed to a thickness dimension of 4 cm and a depth dimension of 5 cm.

  Thereby, even when the thickness dimension of the central part 5 is thick, the operator can grip the cushioning material 1 with the gripping part 4, so that it is easy to grip, and the cushioning material 1 can be inserted between the luggage and pulled out between the luggage. This can be easily performed, and the efficiency of the work using the cushioning material 1 is increased.

  In order to make it easier to grip the cushioning material 1, grooves 6 </ b> A and 6 </ b> B having a substantially semicircular cross-sectional shape are provided on both sides of the flat plate 2 over the entire circumference of the boundary portion between the grip portion 4 and the central portion 5. ing. As a result, when the operator grips the cushioning material 1, the finger is easily caught by the grooves 6 </ b> A and 6 </ b> B. The depth dimensions of the grooves 6A and 6B are also constant regardless of the thickness dimension of the central portion 5 as in the thickness dimension of the grip portion 4 and the depth dimension to the central portion 5. However, when the grooves 6A and 6B are provided opposite to each other on the both sides of the flat plate 2, the thickness dimension of the cushioning material 1 in this portion is reduced, so that the depth dimension of the grooves 6A and 6B is the recess 3A. The depth is preferably smaller than the depth of the recess 3B.

  A second embodiment of the present invention will be described with reference to FIG. The cushioning material 1 of FIG. 2 is also the same as the case of FIG. And the buffer material 1 has the cushioning property and shock absorption property similar to the buffer material 1 of FIG. 1 by providing the several recessed part 3A and the recessed part 3B in the center part 5 of the both sides | surfaces of the flat plate 2, respectively. ing.

  However, in the cushioning material 1 in FIG. 2, the depths of the recesses 3A and 3B provided in the center portions 5 on both side surfaces of the flat plate 2 are set to 1/2 or more of the thickness dimension of the center portion 5. Therefore, the distance d between the recesses 3A and 3B is increased by reducing the number of the recesses 3A and recesses 3B formed at positions that face each other and do not overlap. Thereby, even if the buffer material 1 makes the depth dimension of the recessed part 3A and the recessed part 3B more than 1/2 of the thickness dimension of the center part 5, compared with the buffer material 1 of FIG. Since the thickness 5 cm of the central portion 5 is maintained in this portion, the strength is ensured.

  Thus, cushioning properties can be enhanced while ensuring the strength of the cushioning material 1 by increasing or decreasing the number of the recesses 3A and 3B according to the depth dimensions of the recesses 3A and 3B.

  FIG. 3 shows a modification of the grip portion. The cushioning material 1 shown in FIG. 1 and FIG. 2 uses the entire periphery of the outer peripheral edge of the flat plate 2 as the grip portion 4, but in FIG. 3, one side of the outer peripheral edge of the flat plate 9 serves as the grip portion 10. Further, one side surface of the flat plate 9 communicates with one side surface of the grip portion 10 on the same side. The gripping part 10 has a certain dimension that makes it easy to grip the depth dimension and thickness dimension from the edge of the outer peripheral edge of the flat plate 9 to the central part 8 regardless of the thickness of the central part 8, for example, a thickness dimension of 4 cm and 5 cm. In the example of FIG. 3, the thickness of the central portion 8 is 5 cm or more, and the grip portion 10 is a step with respect to the central portion 8.

  A groove 11A is provided at a boundary portion between the grip portion 10 and the central portion 8, and a groove 11B is provided on the surface of the flat plate 9 that communicates with the grip portion 10 and the central portion 8 so as to face the groove 11A. Yes. As a result, when the operator grips the cushioning material 1, the finger is easily caught by the grooves 11 </ b> A and 11 </ b> B. Further, in the flat plate 9 of FIG. 3, as in the cushioning material 1 of FIGS. 1 and 2, the concave portions 7 for enhancing cushioning are formed on both side surfaces of the central portion 8.

  The grip portion 10 shown in FIG. 3 is formed over one entire side of the flat plate 9, but it may be formed in a part of one of the sides, or may be formed in a corner where two sides intersect. May be.

  As described above, the cushioning material according to the present invention improves the cushioning property by forming a plurality of recesses on both side surfaces in contact with the flat plastic bag of foamed plastic. Moreover, the amount of the material can be reduced and the cost can be reduced while the weight of the cushioning material is reduced by the recess.
