Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a printer, for example,
When packing products such as TVs into packing boxes such as cardboard boxes for packing, by placing them between the products and packing boxes, during transportation or storage, such as when dropping, etc. TECHNICAL FIELD The present invention relates to a cushioning material for packaging used to protect a product by absorbing an impact applied from the shock absorber and a method of using the same.

[0002]

2. Description of the Related Art As such a conventional cushioning material for packing, for example, a packing material such as a folded cardboard, styrofoam, or a combination thereof is used. However, corrugated cardboard can be used if it is roughly shaped, but cannot be used if it is desired to have a complicated shape according to the product. Styrofoam, on the other hand, has the advantage that it can be formed into any complex shape.

[0003] Although styrofoam has such advantages, it has a problem that not only costs for disposal but also pollution and environmental pollution are caused. For this reason, waste disposal is inexpensive, less likely to cause pollution and environmental pollution, and the used pulp molding method that uses waste paper as a recyclable material is used for packaging. In recent years, it has begun to be used as a shock absorber.

[0004] The buffer for packing formed by this pulp molding method is, for example, cutting a used recovered paper, putting a male mold in a raw material dissolved by adding water and chemicals, and applying water in vacuum. After punching and drying, a product formed into a desired shape can be obtained. A well-known applied product is, for example, a “egg protection pack” for storing and protecting eggs.

[0005] The cushioning material for packing by the pulp molding method according to such a process is called a soft type, but in addition to this, there is no solid space on the back side of the product supporting surface of the cushioning material for packing due to hydraulic pressure. There is also a so-called hard type according to a molding method similar to forging.

As the cushioning material for packing by the soft pulp molding method, for example, the one shown in FIG. 6 is used. As shown in the figure, a product 11 to be packed is packed in a cardboard box 12. At the lower end portions of the product 11, packing cushions 13 and 14 formed by pulp molding are provided.
The packing buffers 15 and 16, which are also formed by pulp molding, are disposed between the cardboard box 12 and both upper ends of the product 11.

[0007]

However, such conventional cushioning bodies for packing 13 to 16 have a die-cutting direction at the time of manufacture in the direction of arrow A in the figure (up and down direction in the figure). Vertical portion 13a extending in the vertical direction in FIG.
14a, 15a and 16a are durable and hard to bend against a force applied in the vertical direction in the figure, and exhibit high rigidity against vertical displacement of the product 11.

For this reason, when the cardboard box 12 is dropped from the bottom, which is likely to occur during transportation, an impact force is applied to the vertical portions 13a and 14a in the direction of arrow B in the figure due to the gravitational acceleration of the product 11. Due to the high rigidity of the vertical portions 13a and 14a, the impact force is not absorbed, the reaction force of the impact force acts on the product 11 in the opposite direction, and the product 11 cannot be protected from the impact force. There is a problem in that there is a risk of causing damage or failure of the eleventh embodiment.

Accordingly, the present invention is directed to a packaging buffer formed by a pulp molding method, which is capable of effectively absorbing an externally applied impact force and protecting a packaged object from damage or failure. It is an object of the present invention to provide a shock absorber for use and a method for using the same.

[0010]

In order to solve the above-mentioned problems, the present invention comprises a plurality of packages arranged around a packaged object in a packing box to buffer and protect an external impact applied to the packaged product. In a packing buffer formed by using a mold from a pulp-based material by a pulp molding method, a shape is formed in such a manner that a direction in which a mold is removed at the time of molding matches a horizontal direction at the time of use, and is formed in the packing box. And the packaging cushion is formed in a shell shape, and is formed on the back side of the surface in contact with the article to be packed. The gap is deformed so as to contract when an external impact is applied to the packaged object.

[0011] According to the cushioning body for packing having such a configuration,
The packing cushion is formed in a shape such that the mold removal direction at the time of molding matches the horizontal direction at the time of use, and is arranged in the packing box so that the mold removal direction at the time of molding matches the horizontal direction. Therefore, it is possible to arrange the cushioning member for packing so as to easily absorb the impact force applied from above and below, and it is possible to protect the packaged object from damage or failure by absorbing the impact force.

The packing cushion is formed in a shell shape so that a void formed on the back side of the surface in contact with the packaged object is deformed so as to contract when an external impact is applied to the packaged object. Therefore, the shock absorber applied from above and below can be effectively absorbed by the deformation of the cushioning material for packing so that the void portion contracts, and the packaged object can be protected from damage or failure.

[0013]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 to FIG. 5 are views showing a packaging cushion and a method of using the same according to a first embodiment of the present invention.

FIG. 1 is a view showing a cardboard box (packing box) 2 showing a state in which a product (object to be packed) 1 is packed therein. As shown in the figure, packing cushions 3, 4 formed by pulp molding are provided at both lower end portions of the product 1.
Are disposed between the cardboard box 2 and packing cushions 5, 6 also formed by pulp molding at the upper end portions of the product 1.

Of the packing buffers 3 to 6, for example, the packing buffer 4 is formed as shown in FIGS. FIG.
FIG. 3 is a diagram showing a right end portion of the packing buffer 4 shown in FIG. 2 cut away so that a cross section of the end portion can be seen. The packing buffer 4 has various concave portions 4a to 4d formed according to the shape of the product to be packed.

Each of the packing cushions 3 to 6 has a mold release direction at the time of manufacture thereof, which is indicated by an arrow C in FIG. 1. A draft angle is formed. For example, as shown in FIG.
Slope is formed on each of the upper, lower, and middle surfaces in the figure so that the dimension in the height direction becomes smaller as going in the opposite direction to the left side, that is, as going to the left side in the figure.

For this reason, the packing buffer 4 is provided with a cardboard box 2 if no measures are taken due to the draft of the lower surface thereof.
When the product 1 is placed on the bottom, the product 1 cannot be erected as shown in FIG. In order to prevent such a situation, as shown in FIG. 4, a rib (projection) 9 is formed on the lower surface 4e of the cushioning body 4 for packing.

By forming the ribs 9 on the lower surface 4e of the packing buffer 4, the packing buffer 4 falls down toward the center of the cardboard box 2 when placed on the bottom of the cardboard box 2. , And the three sides of the packing cushion 4 can be reliably brought into contact with the wall surface of the cardboard box 2.

For this reason, the distance between the packing cushion 4 and the corners 3a, 4f of the packing cushion 3 is narrow, as in the case where the packing cushions 3, 4 fall to the center of the cardboard box 2. Therefore, it is possible to prevent the product 1 from being unable to be put in the meantime, to improve the workability at the time of packing, and to be suitable for automatic packing by a robot or the like.

In addition to the above-mentioned operation, the rib 9 has a function of buffering the product 1 with a higher elasticity when the product 1 is subjected to a downwardly displacing shock than in the case of the above-described deformation. ing. Therefore, it is preferable that the shape, size, number, and the like of the ribs 9 are set in consideration of the magnitude of the impact applied to the packing buffer 4 and the elastic modulus of the material. With respect to the point that such a rib 9 is formed on the lower surface 4e, the packaging cushion 3 has the same configuration.

As shown in FIG. 2, a convex portion 7 is formed on the ridge 4h in the vertical direction of the cushioning member 4 for packing. Such a convex part 7 is formed by the same mold with the other most part of the packing buffer 4. The protrusions 7 are also formed on the ridge lines on the wall surface side of the cardboard box 2 of the packing buffers 3, 5, and 6 other than the packing buffer 4.

Next, a method of using the packing buffers 3 to 6 when the product 1 is packed using the cardboard box 2 and the packing buffers 3 to 6 will be described. First, as shown in FIG. 1, packing cushions 3 and 4 are placed on both ends of the bottom of the cardboard box 2. In this case, as shown in FIG. 1, the packing cushions 3 and 4 are placed in such a direction that the die-cutting direction C coincides with the horizontal direction.

At this time, even if the lower surface 4e of the packing buffer 4 has a slope, the rib 9 is tapered by the slope.
Is formed, so that the packing buffer 4 is
Can be placed upright on the bottom of the device. Since the similar ribs 9 are formed on the packing buffer 3, the packing buffer 3 can be similarly placed upright on the bottom of the cardboard box 2.

Next, the corners 3a, 4 of the packing cushions 3, 4
f, the product 1 is inserted and stored, and is locked to the corners 3c, 4n on the base end side of the receiving surfaces 3b, 4k of the packing buffers 3, 4, so that the product 1 is packed. Is placed at the position shown in FIG.

Next, packing cushions 5 and 6 are placed on both ends of the product 1 from above so that predetermined positions 5a and 6c are in contact with each other. Also in this case, the substrate is placed in such a direction that the die removing direction C coincides with the horizontal direction. Finally, the lid 2a of the cardboard box 2 is closed, and a packing tape is attached to the joint of the lid 2a to complete the packing.

In such a cardboard box 2 using the packing buffer 4 for packing, when an impact force is applied from the outside that displaces the product 1 downward in FIG. The thickness of the receiving surface 4k of the packing buffer 4 and the thickness of the lower surface 4e are reduced so that the gap R formed between the thicker portion of the receiving surface 4k and the thicker portion of the lower surface 4e contracts. The parts are deformed so as to approach each other, and the deformation of the thick part absorbs an impact force to protect the product 1 from damage or failure. The packing buffer 3 operates similarly.

Further, when a very large impact force exceeding a predetermined value is applied from the outside such that the product 1 is displaced downward in FIG. 1, as described above, the lower surface 4e and the receiving surface 4k
In addition to absorbing the impact force due to the deformation of the thick portion of each of the ribs, the rib 9 and the vertical portion 4m as shown in FIG.
However, the product 1 is firmly received so as not to be displaced too much, so that the basic packing state and posture of the product 1 can be prevented from being largely collapsed.

At this time, the rib 9 is slightly compressed and deformed, and this deformation can absorb an impact force that cannot be absorbed by the deformation of the thick portion. For example, 6
According to the present invention, the impact acceleration on the product 1 in a similar state can be reduced to 40 G, while the impact acceleration on the product 1 due to the bottom drop from the height of 0 cm was 60 G in the past. Has been proven.

Further, when an impact force for displacing the product 1 upward in FIG. 1 is applied from the outside, for example, a gap between the upper thick portion 6a and the intermediate thick portion 6b of the packing buffer 6 is generated. Is deformed so as to shrink, that is, the upper thick portion 6a and the lower thick portion 6b of the packing buffer 6 approach each other, and absorb the impact force by this deformation. The product 1 can be protected from damage or failure.

Since the packing cushions 3 to 6 are formed with the convex portions 7 as described above, when the packing cushions 3 to 6 are stored in the cardboard box 2, the convex portions 7 are formed. The packing cushions 3 to 6 are prevented from rattling in the cardboard box 2 due to a slight gap by being pressed against the wall surface of the cardboard box 2 and, in some cases, the projections 7 biting into the wall surface of the cardboard box 2. Calm down (stable storage),
The product 1 can be stably held.

In the above embodiment, the case where two packing cushions are used on the lower side of the product 1 and two on the upper side has been described. Two in total, or two in the lower part of the product 1 and three in the upper part, or five or more in various combinations of upper and lower parts, May be used in combination with other types of packing buffers.

Further, in the above embodiment, the case where the rib 9 is formed on the lower surface 4e of the packing buffer 4 has been described. However, if the packing buffer 4 can be erected without tilting. The shape of the protrusion, such as a button-shaped protrusion or the like, may be any shape. It is not necessary to limit the number to two (two places) like the rib 9.

[0033]

As described above, according to the present invention, the cushioning material for packing is formed into a shape such that the direction of the mold removal during molding coincides with the horizontal direction during use, and the shape of the cushioning material in the packing box during molding is reduced. Since the die-cutting direction is arranged so as to coincide with the horizontal direction, it is possible to arrange the cushioning material for packing so as to easily absorb the impact force applied from above and below, and to absorb the impact force so as to be packed. Can be protected from damage and breakdown.

The cushioning member for packing is formed in a shell shape, and a gap formed on the back side of the surface in contact with the object to be packed is deformed so as to contract when an external impact is applied to the object to be packed. Therefore, the shock absorber applied from above and below can be effectively absorbed by the deformation of the cushioning material for packing so that the void portion contracts, and the packaged object can be protected from damage or failure.

Further, in the above embodiment, when packing cushions 3 to 6 are stored in cardboard box 2, convex portions 7 formed on each ridge line are pressed against the wall surface of cardboard box 2. The protrusions 7 cut into the wall of the cardboard box 2 to prevent the packing buffers 3 to 6 from rattling in the cardboard box 2 due to a slight gap, so as to calm down, and to stably hold the product 1. be able to.
