This application is based upon and claims the benefit of priority of the prior Japanese Patent Application No. 2008-201762, filed on Aug. 5, 2008, the entire contents of which are incorporated herein by reference.
FIELDThe embodiments discussed herein are directed to a package member, more particularly, to a package member that makes packaging simpler and reduces impact on an object being transported.
BACKGROUNDUpon transportation of electronic components, assembly components, or electronics, a cushioning member is generally placed between an external box and a separate box to protect a packaged article from impact during the transportation. The cushioning member is selected from various types in consideration of the impact resistance, dust aversion, size and weight of an object to be transported, and the size and material of the external box.
For example, for transporting assembly components such as head gimbal assembly (HGA) of magnetic heads that are used in a magnetic memory device, a plurality of HGAs are housed in which dedicated trays. The dedicated trays are stacked and housed in a separate box, and a plurality of separate boxes are housed in an external box to be transported. At that time, a cushioning member formed of polystyrene foam is used to absorb impact.
As illustrated in
At the time of the transportation of general electronics, a cushioning member shaped of plastic sheet is used in addition to a cushioning member shaped of polystyrene foam.
The cushioning member 400 is arranged on the inside bottom of the external box and the cushioning member 401 is arranged to cover the tops of the separate boxes 100 that are fitted in the concave portions 410 of the cushioning member 400. When the cushioning member 401 covers the tops of the separate boxes 100, concave portions 411 of the cushioning member 401 are fitted in the upper portions of the separate boxes 100. Therefore, a part of convex portions 420 and 421 of the cushioning members 400 and 401 are inserted between the separate boxes 100 so that the separate boxes 100 are not in contact with each other.
When impact is applied to the external box (not illustrated), the most of impact energy is absorbed by the plastic sheet of the cushioning members 400 and 401 and the convex portions 420 and 421 of the plastic sheet. Therefore, large impact energy is not directly added to the separate boxes 100.
For example, Japanese Laid-open Patent Publication No. 05-51070 discloses a conventional technology related to a cushioning member for packages, in which a cushioning member is produced by shaping corrugated fiberboard. The conventional technology considers an environment and improves recycling efficiency by using corrugated fiberboard instead of a plastic sheet.
Further, for example, Japanese Laid-open Patent Publication No. 05-16670 discloses a conventional technology using a pouched member having a gas space, of which a volume is variable by sealing air, as a cushioning member. The pouched member functions as a cushioning member by putting therein gas. Then, the pouched member is easily collected and discarded by drawing gas after transportation.
As described above, at the time of the transportation of assembly components such as HGA, a cushioning member made by shaping polystyrene foam has been used. However, because HGA has a sensitive structure, there has been a demand for developing a packaging method for easily absorbing impact at the time of transportation compared with a conventional packaging method.

With reference to
According to an aspect of an embodiment, a package member includes a first cushioning member and a bottom supporting member. The first cushioning member includes concave portions in which bottoms of a plurality of packaged articles are fitted, and a convex portion that is inserted between the packaged articles. The predetermined space is formed at backsides of the concave portions. The bottom supporting member is arranged in the predetermined space in contact with the backsides of the concave portions of the first cushioning member and that is inflatable when charged with air.
The object and advantages of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the claims.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are not restrictive of the invention, as claimed.
Exemplary embodiments of the invention will be explained in detail below with reference to the accompanying drawings.
A package member of a first embodiment includes a cushioning member and a bottom supporting member. With reference to
The first embodiment describes an example of packing four separate boxes in an external box. The cushioning member 500 includes four concave portions 510 (its height is 55 mm) tailored to the width and depth of the separate box. Two cushioning members are arranged at the upper and lower sides of the external box, and the separate boxes are respectively fitted in upper and lower concave portions. Convex portions 520 are formed to be linked to the concave portions 510 and be crossed in the center of the cushioning member. The convex portions 520 are inserted between the four separate boxes. In other words, the separate boxes are fitted in the concave portions 510 by inserting the convex portions 520 between the separate boxes. In the separate box, its width is 140 mm, its depth is 110 mm, its height is 200 mm, and the weight is 600 grams.
A hollow 530 illustrated in
A space 512 is formed at the backsides of the concave portions 510 as indicated by dotted lines of
The gas accommodating unit 610 includes a volume varying unit 611 that swells out by charging gas and coupling units 612 and 613 that are connected to the volume varying unit 611 to be coupled with another gas accommodating unit or the gas charge/discharge unit 620.
The gas charge/discharge unit 620 includes a charge/discharge port 621 that charges and discharges gas, a pipe 622 that is connected to the charge/discharge port 621 to permit the passage of gas into the volume varying unit 611, a coupling unit 623 that is coupled with the gas accommodating unit 610. In addition, the charge/discharge port 621 includes a cock that locks and unlocks the gas that is charged in the gas accommodating unit 610.
In the first embodiment, the bottom supporting member 600 is made of polyvinyl chloride. However, the bottom supporting member 600 may be made of materials other than polyvinyl chloride if the bottom supporting member made of the other materials can be inflated by charging gas and have mechanically sufficient intensity. When seeing the gas accommodating unit 610 from the upper side, its shape is a circle and its diameter is 100 mm. When seeing the gas accommodating unit 610 from the lateral side, its shape is an ellipse and its thickness is 55 mm (gas-charged state) as illustrated in
Next, an example of a procedure of packing four separate boxes by using the cushioning member 500 and the bottom supporting member 600 as described above will be described with reference to
First, in
Next, the cushioning member 500 is arranged from the top of the bottom supporting member 600. The backsides of the concave portions 510 of the cushioning member 500 contact the gas accommodating units 610 of the bottom supporting member 600. The gas charge/discharge unit 620 is arranged through the hollow 530 (see
The lower portions of the separate boxes 100 are respectively fitted in the four concave portions 510 of the cushioning member 500. Because the gas accommodating units 610 are arranged at the backsides of the concave portions 510, the cushioning member 500 is not bended due to the separate boxes 100 fitted in the concave portions 510 (
An upper cushioning member 501 covers the separate boxes 100 arranged in the cushioning member 500 from the top of the box. Although the cushioning member 500 and the cushioning member 501 have the same shape, a member disposed at the bottoms of the separate boxes 100 is the cushioning member 500 and a member disposed at the tops of the separate boxes 100 is the cushioning member 501. At this time, the concave portions of the cushioning member 501 are fitted in the upper portions of the separate boxes 100. As a result, the convex portions of the cushioning member 501 are inserted between the separate boxes 100 (
When the arrangement of the cushioning member 501 is finished, the cock of the charge/discharge port 621 of the bottom supporting member 600 is opened to draw the air charged in the gas accommodating units 610. In this way, the gas accommodating units 610 wither away, and thus the gas accommodating units 610 is downward detached from the backsides of the concave portions 510 of the cushioning member 500 (
If the upper cover of the external box 200 is closed, the packaging work is finished (
As illustrated in
According to the first embodiment, the package member accommodates the four separate boxes in the external box. The gas accommodating units of the bottom supporting member respectively contact the bottoms of the separate boxes via the cushioning member. According to a second embodiment, a package member accommodates eight separate boxes in an external box. The package member includes two upper cushioning members, two lower cushioning members, and a bottom supporting member having two gas accommodating units. The second embodiment will be described with reference to
The bottom supporting member 800 includes two gas accommodating units 811 of which diameters are 200 mm. The other of the bottom supporting member 800 is similar to the bottom supporting member 600.
An example of packing using the cushioning member 700 and the bottom supporting member 800 will be below explained.
After the work as illustrated in
As described above, according to an embodiment, a plurality of packages are fitted in the concave portions of the first cushioning member, and the convex portion of the first cushioning member is inserted between the packages. Further, a bottom supporting member is arranged between the backsides of the concave portions of the first cushioning member and the bottom surface of the external box, which prevents a lower cushioning member from bending when the packages are arranged on the lower cushioning member if the bottom supporting member is filled with air.
Moreover, a bottom supporting member filled with air is arranged at the backsides of the concave portions of the first cushioning member. Therefore, the cushioning member is not bend when packaged articles are fitted in the concave portions of the cushioning member. Thus, a convex portion of a cushioning member can be easily inserted between the packaged articles, and the efficiency of a packaging work can be improved. Moreover, because the bottom supporting member suppresses the bending of the first cushioning member, the thickness of the first cushioning member can be made thin and impact at the time of transportation can be absorbed.
