Description

[Detailed description of the invention] [Industrial application field] The present invention is suitable for packaging objects such as fluorescent lamps, which have a straight tube diameter that is long in the tube axis direction and is easy to break. The present invention relates to a package used for packaging.

[Conventional technology]

This type of conventional packaging includes, for example,
There are "packaging cases" disclosed in Japanese Utility Model Publication No. 24291 and Japanese Utility Model Publication No. 47-24292. This "packaging case" consists of a sheet in which a plurality of gutter-like grooves are arranged side by side with both ends open, and the edge of each gutter-like groove is inserted from the bottom of each gutter-like groove in a direction that crosses the gutter-like grooves. A plurality of cuts are formed until reaching a connecting band that connects with each other. By folding the sheet along the cut-out portion as a boundary, a small chamber in which an object to be packaged, such as a fluorescent lamp, is accommodated can be formed in the opposing gutter-like grooves.

Another example, as disclosed in Japanese Utility Model Application Publication No. 58-188878, is made of styrofoam and has a concave portion at the top and bottom that corresponds to the shape of the packaged object, such as a straight tube fluorescent lamp. The packaging material is made of cardboard and has recesses corresponding to the shape of the packaging material arranged in parallel on the upper and lower sides of the packaging material. There are known devices that are arranged at both ends of an object.

[Problem that the invention attempts to solve]

However, in the case of the former "packaging case", when stacking sheets with a series of small cells in multiple tiers so that the small cells in each tier overlap, the shock absorption capacity is insufficient, so the gap between the sheets in each tier is insufficient. A partition plate is required. For this reason, the number of materials used during packaging increases, and the workability of packaging materials decreases. Furthermore, when sheets are stacked in multiple tiers, a large dead space is formed between four adjacent compartments, resulting in poor packaging efficiency per packaging box. Furthermore, in order to reduce dead space, when sheets are simply stacked so that the compartments of adjacent tiers are staggered, the dimensions of the packaging box corresponding to each packaged item are usually determined, so The number of compartments in the tiers, that is, the number of items to be packaged, differs, making management of the number of items to be packaged in one box complicated. Furthermore, since the shapes of the sheets in adjacent stages are different, a problem arises in that a large number of molds are required.

On the other hand, in the latter structure, when packaging bodies made of styrofoam and cardboard in a plurality of layers, a partition plate is required as in the above case, and workability becomes worse. Furthermore, in the case of a packaging body made of cardboard, the impact absorption capacity is low, so that it has disadvantages such as the need to individually wrap the items to be packaged first.

In addition, as a solution to the above problem, as shown in FIG. 3, the ridges 21 and troughs 22 are alternately arranged in parallel, and both ends are terminated at the ridges, and the dimensions are It is conceivable that the packaging body 23 has one end horizontally extended in order to accommodate the packaging objects 26, so that the same number of items 26 can be accommodated in each stage.

However, in such a structure, the packaging box 2
Although the dead space within 7 is significantly reduced, the packaged object storage section 24 formed at one end
In addition, since the opening 25 is formed, the packaged object 26 contained therein is in a state where it is easy to move. For this reason, the packaged article 26 at the above-mentioned portion was easily damaged by external impact, and even when a drop test was performed, good results could not be obtained.

[Means for solving problems]

In order to solve the above-mentioned problems, the package of the present invention is made of a cushioning material and has a corrugated plate shape with alternating peaks and valleys, and each peak has an upwardly protruding part. A contact portion is formed, and each trough is formed with a contact portion that protrudes downward, and one terminal end in the direction of wave propagation extends upward to approximately the same height as the contact portion on the crest side. The other end portion extends downward to approximately the same height as the contact portion on the trough side.

[Effect]

When a packaged object is packaged with this package, the entire circumference of each packaged object is covered by the packages on both sides of the packaged object. In addition, the shock absorbing force in the direction of the contact portion is particularly enhanced at the contact portions formed at each peak and valley portion. Furthermore, when the packages are stacked in multiple stages, the packaged items storage portions are formed at alternate positions in the packages in the adjacent stages, thereby reducing dead space.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

As shown in FIG. 1a, the package 1 according to the present invention has a corrugated plate shape having peaks 2 and valleys 3 alternately.

A peak-side contact portion 4 that projects upward and a valley-side contact portion 5 that projects downward are formed approximately in the center of the peak portion 2 and the valley portion 3 in the longitudinal direction. , 5 have recesses 6 formed therein. One end of the package 1 in the width direction, that is, the end of the corrugated plate in the direction of wave propagation, has a ridge end and a trough end, and the ridge end has a ridge abutment. A peak-side abutting flange 7 having substantially the same height as the trough-side abutting portion 5 is formed at the trough-side terminal end. Further, at the rear end portions of the crests 2 and troughs 3 on the longitudinal sides of the package 1, rear-end troughs 9 are alternately formed on the ridges 2 side, and rear-end ridges 10 are formed on the troughs 3 side. ing. As a result, the rear end of the trough 3 and the rear end of the peak 3 on the back side are closed. On the other hand, the front end is an open end.

The above-mentioned package 1 has the same shape on the front and back, and when turned over, the peak side and the valley side are reversed.

Further, as described above, the package 1 has a rear end peak 10
In the case of a configuration having a rear end trough 9, as shown in FIG.
1 is provided.

In the above configuration, as shown in FIG. 1 and the packaging bodies 11 are stacked alternately, whereby a fluorescent lamp 12 is placed in the space created between the troughs 3 on one side and the peaks 2 on the other side of the packaging bodies 1 and 11 that face each other. ...to be stored.

Specifically, first, the package 11 is placed at the bottom of the packaging box 13, and each valley 3 of the package 11 is
... Place the fluorescent lamp 12 ... on top. When the fluorescent lamps 12 are arranged on the first package 11 in this way, the second package 1 is placed from above to cover the first fluorescent lamps 12. Next, after arranging the second tier fluorescent lamps 12 on top of each valley 3 of the second tier packaging 1 in the same manner as above, the third tier packaging 11 is placed on top of the second tier fluorescent lamps 12. The third tier of fluorescent lamps 12 are placed above each valley 3 of this package 11.
Arrange... In this way, package 1 and package 11
The fluorescent lamps 12 .

In packaging using the packaging bodies 1 and 11 as described above,
As shown in FIG. 2, the peak-side abutting portion 4 and the peak-side abutting flange 7 of the first-stage package 11, and the valley-side abutting portion 5 and the valley-side abutting flange 8 of the second-tier package 1.
Similarly, the peak-side contact portion 4 and the peak-side contact flange portion 7 of the second-stage package 1 and the valley-side contact portion 5 and the valley-side contact portion of the third-stage package 11 contact each other. The collar portions 8 are in contact with each other.

By this, five pieces having a closed cross section at each stage,
That is, the same number of packaged object storage sections 14... are formed,
Fluorescent lamps 12 are housed in these packaged object housing sections 14.

By being packaged as described above, the fluorescent lamp 12 is completely surrounded on its entire circumference by the packages 1 and 11, making it less susceptible to external shocks. In addition, in the above packaged state, the peak-side contact portion 4 and the valley-side contact portion 5 are located in the vertical direction of the fluorescent lamp 12,
In addition, recesses 6 are formed in both abutting portions 4 and 5 to add flexibility, thereby providing a high shock-absorbing ability, especially against impacts from above and below. Furthermore, the fluorescent lamp 12 in the packaging box 13 is further protected by the peak-side abutting flange 7 and the trough-side abutting flange 8 of the packages 1 and 11, and by the rear-end crest 10 and rear-end trough 9.
An appropriate space is secured between the packaging box 13 and the packaging box 13, and a sufficient buffering function can be exerted against impacts from the front, rear, left, and right directions.

In addition, in packaging using the present packaging bodies 1 and 11,
Since the packaging bodies 1 and 11 have a peak-side abutting flange 7 and a trough-side abutting flange 8, as well as a rear peak 10 and a rear trough 9, the fluorescent lamps 12 can be packaged vertically side by side. It is also possible to do so. In addition, the fluorescent lamp 12
If the length of the fluorescent lamp 12 is short, it can be packaged with one package 1 for each tier corresponding to the length of the fluorescent lamp 12; conversely, if the fluorescent lamp 12 is long, the fluorescent lamp 12 The fluorescent lamp 12 is constructed by arranging the packaging bodies 1 and 11 at both ends of the fluorescent lamp 12, and by arranging the packaging body 1 without the rear end peak 10 and the rear end trough 9 at the center of the fluorescent lamp 12. Just protect it.

[Effect of idea]

As described above, the package according to the present invention is made of a cushioning material and has a corrugated plate shape having alternating peaks and valleys, and each peak has an upwardly protruding abutting part. A contact portion protruding downward is formed in each trough, and one terminal end in the wave traveling direction extends upward to approximately the same height as the contact portion on the crest side. On the other hand, the other end portion extends downward to approximately the same height as the contact portion on the trough side.

Therefore, when the objects to be packaged are packaged using this package, each object to be packaged is accurately covered by the package and is reliably protected against external impact.

In addition, by having contact parts at each peak and trough, the shock absorption power is particularly enhanced in the direction of the contact parts, so there is no need for a separate partition plate to add shock absorption function. . Therefore, the number of materials required for packaging can be reduced, and the efficiency of packaging work can be improved.

Furthermore, when the packages are stacked in multiple tiers, the packages in the adjacent tiers are formed with packaged item storage sections at alternate positions, reducing dead space and reducing the amount of space required for each packaging box. This has the effect of increasing packaging efficiency per unit.
