Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cushioning package suitable for cushioning and protecting a packaged object to be packaged and transported.

[Prior Art] In order to transport an article, it is generally adopted that the article is stored in a packaging member such as a cardboard box, and a cushioning material is interposed between the member and the article.
Some of the goods include electronic parts, precision equipment, etc. that do not like impact force or vibration during transportation, and conventional packaging methods are not always satisfactory for these items, so there is a need for simpler packaging with better cushioning effects. It had been requested.

[Problems to be solved by the invention] The present invention has been made in view of the above circumstances, and its purpose is to provide a package having a cushioning material that has an excellent cushioning effect, is easy to handle, and can be implemented at low cost. It's about doing.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a first buffer member made of a frame-shaped foamed resin that surrounds an object to be packaged, and A portion that abuts and supports the outer periphery of the packaged object is formed from a locking portion that projects obliquely from the peripheral edge of the frame, and also faces and supports the first buffer member. A second buffer member is provided, and the support portion is formed from a trapezoidal three-dimensional shape having a hole,
Surrounding and supporting the packaged object by a pair of cushioning materials made of a combination of the first and second cushioning members,
The present invention is characterized by a package having a cushioning material, which is housed in a packaging member such as a cardboard box.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 shows a first buffer member 1 and a second buffer member 2.
and In the case of this embodiment, both are formed so as to be integrally moldable as shown, but of course they may be formed separately. All of these are made of foamed resin such as foamed polystyrene and foamed polyethylene.

The first buffer member 1 is formed from a rectangular frame-like member, and locking portions 3 are formed at its four corners.
The locking portion 3 is formed to protrude inward from the corner portion, and a receiving portion 4 is formed at the protruding end side for abutting and supporting an object to be packaged (not shown). In this embodiment, the receiving portion 4 is formed from a right-angled concave portion so as to come into contact with a corner of the square-shaped object 1 to be packaged. Further, the locking portion 3 projects obliquely with respect to the peripheral edge of the frame, forming an inclination angle θ. It is necessary that θ<90°, preferably 15°≦θ≦75°, more preferably 30°≦θ≦60°. The locking portion 3 is formed into a triangular projecting shape due to the recessed portion and the inclination angle θ. In addition, when the shape of the locking part 3 is formed in an arc shape as shown in FIG. It means the angle that a straight line makes with a straight line extending from the surface of the receiving part 4 of the locking part 3.

The area of the receiving part 4 is preferably determined so that the buffering G value when a package containing a packaged object weighing 20 to 1 kg is dropped from a height of 60 cm to 1 m is within 15 G to 40 G.

The objects to be packaged are held by receiving portions 4 disposed facing each other and housed within the frame. Further, a hole 5 is formed through a part of the locking part 3. Although the punch hole 5 is formed in the shape of a long and narrow hole in this embodiment, it may have another shape. Further, although not clearly shown in the drawings, each intersection portion is appropriately formed into an arc shape in order to eliminate stress concentration.

The second buffer member 2 is formed from a surface portion 6 of an appropriate length that faces the first buffer member 1, and two protruding support portions 7. Note that the thickness dimension in the direction perpendicular to the plane of the paper is the same as that of the first buffer member 1 and is formed from a material having an appropriate thickness. There is a small step 8 in the middle part of the surface part 6.
is formed to prevent the surface area 6 from touching the entire surface. Further, a V-groove 9 is formed at the connection point between the surface portion 6 and the support portion 7, but this is formed in order to integrally form the first and second buffer members 1 and 2 as described above. It is something. Depending on the shape of the locking portion 3, a V-groove may not be formed. A punch hole 10 corresponding to the shape of the support part 7 is formed through the support part 7 . Each part of the second buffer member 2 is also formed into an arc shape as appropriate to reduce stress concentration.

FIGS. 2 and 3 show that the bonding surface 13 of the second buffer member 2 is coated with an adhesive, and this is pasted on one side of the first buffer member, which are placed facing each other and stored in a cardboard box 11. , shows a state in which a square-shaped packaged object 12 is sandwiched and surrounded and supported.

That is, the second buffer member 2 faces one side of the first buffer member 1, and also faces the first buffer member 1.
supports the packaged material 12 that is surrounded and held by. As a result, the material to be packaged 12 is supported by the support portion 7 of the second buffer member 2 and the peripheral edge of the first buffer member 1, and is housed in the cardboard box 11.

[Effect] Next, the operation of this embodiment will be explained.

A packaged object 1 surrounded and held by the first buffer member 1
When an impact force is applied to the first shock absorbing member 2 in a direction along the plane of the first shock absorbing member 1 or when the first shock absorbing member 2 vibrates, the first shock absorbing member 2 is supported by the triangular receiving portion 4 of the locking portion 3 . The triangular receiving portion 4 is formed protrudingly at the inclination angle θ as described above, so it is highly flexible and acts to absorb the above-mentioned force or vibration. Further, the punched holes 5 function to alleviate the force or vibration in this direction, and also function to reduce stress concentration at the corner portions of the frame.

On the other hand, the impact or vibration of the packaged object 12 in a direction perpendicular to the above-mentioned planar direction is received and alleviated by the support portion 7 of the second buffer member 2. That is, the impact force and vibrations are absorbed by the cushion formed by the trapezoidal three-dimensional shape of the support part 7 and by the buffer provided by the punched hole 10.

As described above, the first and second buffer members 1 and 2
By this combination, the packaged object 12 is cushioned and supported from three directions, and can be cushioned or absorb kinetic energy. Therefore, it is fully applicable to electronic equipment, precision equipment, and other items that are sensitive to shock and vibration. Further, as described above, this embodiment is simple and can be implemented at low cost by arranging the integrally formed shock absorbing members facing each other.

Although this embodiment has been described with respect to a rectangular packaged object, the present invention is similarly applicable to a cylindrical or other shaped packaged object. That is, by forming the shape of the protruding end side of the locking part 3 that comes into contact with the outer periphery of these objects to be packaged to match the outer periphery of the object to be packaged, these objects to be packaged can be wrapped in the same manner as above. It will be surrounded by support and shock and vibration will be absorbed as well.

[Effects of the invention] As is clear from the above explanation, according to the invention, the simple structure of the cushioning material provides shock in three directions, and has the effect of absorbing kinetic energy due to shock and vibration. It can be raised.
