[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an article packaging body and an article packaging method for packaging an article such as an electronic component.
[0002]
[Prior art]
Conventionally, when electronic parts are shipped, the electronic parts are stored in a plastic tray. A hole is formed in the plastic tray, and the electronic component is housed in the hole and shipped. However, since plastic trays are difficult to discard, cardboard trays are widely used in recent years to store electronic components. The article packaging body using this cardboard tray will be described with reference to FIG.
[0003]
As shown in FIG. 7, the article packaging body C includes a cardboard tray 70 that stores electronic components 74 and film sheets 77 and 78. The corrugated cardboard tray 70 is obtained by superimposing a corrugated cardboard 72 on the upper surface of a paper board 71 serving as a bottom plate. The cardboard 72 has a hole called a pocket 75 for storing the electronic component 74, and the pocket 75 is set to a size larger than the electronic component 74. After the electronic component 74 is stored in the pocket 75, film sheets 77 and 78 are attached to the upper and lower surfaces of the cardboard tray 70.
[0004]
[Problems to be solved by the invention]
However, as shown in FIG. 7, since the size of the pocket 75 is larger than the electronic component 74, the electronic component 74 is not fixed and moves inside the pocket 75 when shipped. Since the electronic component 74 moves and rubs against the paper board 71 that is the bottom plate of the cardboard tray 70, paper dust is generated from the paper board 71. Further, the electronic component 74 may collide with the corrugated cardboard 72 which is the inner wall surface of the pocket 75 and damage the outer shape. For this reason, a method is adopted in which the shape and size of the pocket 75 are approximated to the shape and size of the electronic component 74 and the electronic component 74 is fixed to the pocket 75.
[0005]
By approximating the pocket 75 to the size of the electronic component 74 and the like, the electronic component 74 is prevented from moving in the pocket 75, and generation of paper dust and external damage to the electronic component 74 are prevented. However, there are a plurality of types of electronic components 74, and the shape and size are different for each type. For this reason, it is necessary to change the size of the pocket 75 according to the type of the electronic component 74, and a plurality of types of cardboard 72 having the pocket 75 are required as with the electronic component 74. For this reason, the cardboard tray 70 for storing the electronic component 74 cannot be limited to one type.
[0006]
The fact that the cardboard tray 70 cannot be limited to one type is very troublesome in the process of punching the cardboard 72 and making the pocket 75. Even in the operation of storing the electronic component 74 in the cardboard tray 70, the fact that the cardboard tray 70 cannot be limited to one type also causes a reduction in the efficiency of the storage operation.
[0007]
The present invention has been conceived under such circumstances, and can be applied to packaging of various articles having different sizes and shapes, and can prevent the occurrence of paper dust and the external damage of electronic components. The object is to provide an article packaging body and an article packaging method.
[0008]
DISCLOSURE OF THE INVENTION
In order to solve the above problems, the present invention takes the following technical means.
[0009]
That is, the article packaging provided by the first aspect of the present invention is a corrugated cardboard tray formed by stacking corrugated cardboard with pockets for storing articles on the upper surface of a paper board serving as a bottom plate, A plurality of articles stored in a pocket of the cardboard tray, and a bag-like covering the cardboard tray storing the articles, and a packaging film sealed in a vacuumed state, The paper board is made of cardboard, and the cardboard tray is formed with a plurality of the pockets. Each of the pockets contains two or more articles, and the packaging film has the pockets. portion covering is characterized in that it is pressed against the article to the bottom of the pocket by the pressure difference between the inside and outside pocket.
[0010]
In the present invention, the pressure in the pocket is reduced by evacuation to draw the portion of the packaging film covering the pocket toward the bottom of the pocket. The article in the pocket is pressed against the bottom of the pocket by the packaging film which is evacuated and fixed. For this reason, when the article package is shipped to the user, the article does not move in the pocket, and does not rub against the paper board that is the bottom plate of the cardboard tray. For this reason, paper dust is not generated from the paper board. Furthermore, since the article does not collide with the cardboard which is the inner wall surface of the pocket, there is no external damage. By preventing damage to the outer shape of the article, deterioration of the quality of the article is also prevented.
[0011]
As described above, in the present invention, the article is fixed by the evacuated packaging film. The conventional article packaging body fixed the article in the pocket by matching the size and shape of the pocket to the article, but the article packaging body of the present invention fixes the article with a vacuumed packaging film, There is no need to match the size of the pocket to the article. Since the article packaging body of the present invention can package articles of various sizes, the present invention can share the article packaging body without considering the size of the article.
[0012]
In the article packaging body of the present invention, the packaging film can be evacuated using the cross-sectional structure of the cardboard. If the gap between the liner paper constituting the corrugated cardboard and the corrugated core paper is a suction hole, the packaging film can be evacuated from the gap (suction hole). It is not necessary to form a new suction hole in the cardboard in order to evacuate the packaging film. Since there are a plurality of gaps between the liner paper and the corrugated core paper, it is convenient for adjusting the vacuuming force. Furthermore, since the moisture in the pocket is removed by evacuation, the quality of the article is not deteriorated by the moisture. Further, since the paper board made of cardboard is also composed of liner paper and corrugated core paper, the entire cardboard tray can be evacuated. Furthermore, if the paper board material and the cardboard material are the same, the manufacturing efficiency of the cardboard tray can be improved. Furthermore, it becomes possible to reduce the manufacturing cost of the cardboard tray.
[0014]
In a further preferred embodiment of the present invention, the article is an electronic component. Since the outer shape of the electronic component is easily damaged by friction when moving in the pocket, the article packaging body of the present invention exhibits a great effect when packaging the electronic component.
[0015]
Article wrapping method provided by the second aspect of the present invention is formed by overlapping a cardboard having a plurality of pockets is opened for accommodating a plurality of articles on the upper surface of the cardboard paper plate with a bottom plate After storing two or more articles in each pocket of the cardboard tray, the cardboard tray is covered with a bag-like packaging film, and the packaging film is sealed in a vacuumed state. It is characterized by doing.
[0016]
The article packaging method of the present invention is a method using the corrugated cardboard tray described above. A cardboard tray containing articles in a pocket is covered with a bag-like packaging film, and the packaging film is evacuated. If the packaging film presses the article against the bottom of the pocket and then the opening of the packaging film is sealed, the cardboard tray and the article can be completely packaged. The evacuation of the packaging film uses a cross-sectional structure of cardboard. If the gap between the liner paper constituting the cardboard and the corrugated core paper is a suction hole, the packaging film can be evacuated from the gap (suction hole).
[0017]
As described above, since the article packaging body of the present invention can be applied to packaging various articles having different sizes and shapes, the present invention enables the sharing of the article packaging body. Further, by fixing the article in the pocket with the vacuum-wrapped packaging film, it is possible to prevent external damage to the paper dust and the article. When the packaging film is evacuated, the gap between the liner paper constituting the corrugated cardboard and the corrugated core paper can be used as a suction hole, so there is no need to newly form a suction hole. If an article is to be fixed in a pocket formed in another material tray (for example, a plastic tray) by evacuation, a new suction hole must be formed in the plastic tray. Since the cardboard tray in the article packaging body of the present invention does not require labor for forming a new suction hole, the production of the cardboard tray is much easier than the production of the plastic tray.
[0018]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a main part showing an embodiment of an article packaging body according to the present invention, FIG. 2 is a partially enlarged sectional view of a cardboard constituting the article packaging body of FIG. 1, and FIG. 4 is a cross-sectional view taken along line AA of the article package shown in FIG. 4, and FIG. 4 is a cross-sectional view taken along line B-B of the article package shown in FIG.
[0019]
As shown in FIG. 1, the article packaging body A is a product in which a corrugated cardboard tray 10 containing electronic components 4 is covered with a packaging film 3 that is evacuated. The cardboard tray 10 is obtained by superposing the cardboard 2 on the upper surface of the paper board 1 serving as a bottom plate. The cardboard 2 has a pocket 5 for storing an electronic component 4, and the pocket 5 is sized to store a plurality of electronic components 4.
[0020]
The structure of the cardboard 2 will be described with reference to FIG. FIG. 2A is a longitudinal sectional view of the cardboard 2, and FIG. 2B is a transverse sectional view of the cardboard 2. The corrugated cardboard 2 is a double-sided cardboard, and as shown in FIG. 2, liner papers 21 and 22 are pasted on both sides of a corrugated core paper 23. A gap between the liner papers 21 and 22 and the corrugated core paper 23 becomes a suction hole 25 when the packaging film 3 (see FIG. 1) is evacuated. Therefore, since the packaging film 3 is evacuated, it is not necessary to newly form a groove or a hole in the cardboard 2 as a suction hole.
[0021]
The paper board 1 serving as the bottom board is made of cardboard so that the entire cardboard tray 10 can be evacuated. If the material of the paper board 1 and the material of the cardboard 2 are the same, the cardboard tray 10 can be manufactured efficiently. As shown in FIGS. 3 and 4, the paper board 1 has a structure in which liner papers 11 and 12 are pasted on both sides of a core paper 13 formed into a corrugated shape.
[0022]
The packaging film 3 is a bag-like transparent body. The packaging film 3 is evacuated after covering the cardboard tray 10 containing the electronic component 4 in the pocket 5, and the opening portion is sealed to package the cardboard tray 10 and the electronic component 4. .
[0023]
A state where the electronic component 4 is stored in the pocket 5 of the article packaging body A will be described with reference to FIGS. 3 and 4. As shown in the figure, a plurality of electronic components 4 are accommodated in the pocket 5. Since the pressure in the pocket 5 is lower than the external pressure by evacuation from the suction hole 25, the portion of the packaging film 3 covering the pocket 5 is drawn toward the bottom of the pocket 5. Since the packaging film 3 presses the electronic component 4 toward the bottom of the pocket 5, the electronic component 4 is pressed against the paper board 1 and fixed in the pocket 5. Since the electronic component 4 is fixed, it is not necessary to approximate the size and shape of the pocket 5 to the size and shape of the electronic component 4. Therefore, the article package A can be applied to the packaging of various electronic components 4 having different sizes.
[0024]
As shown in FIG. 1, the corrugated cardboard tray 10 in the article packaging body A is obtained by superimposing one corrugated cardboard 2 on the upper surface of one paper board 1. However, the corrugated cardboard tray 10 is limited to the above structure. Is not to be done. Another embodiment of the article packaging body according to the present invention will be described with reference to FIG. FIG. 5 is a perspective view showing a main part of another embodiment of the article packaging body according to the present invention, and FIG. 6 is an exploded perspective view showing a principal part of a cardboard tray in the article packaging body B shown in FIG.
[0025]
As shown in FIGS. 5 and 6, the article packaging body B is obtained by covering a corrugated cardboard tray 50 containing electronic components 54 with a evacuated packaging film 53. The cardboard tray 50 includes two paper boards 51 and two cardboards 52. The paper board 51 and the cardboard 52 are alternately stacked, and the paper board 51 serves as a bottom plate.
[0026]
The article package B has the same structure as the article package A except that the article package B includes a plurality of cardboards 52 and a plurality of paper boards 52. Although not shown, also in the article packaging B, the gap between the liner paper constituting the corrugated cardboard 52 and the corrugated core paper is a suction hole, and the bag-like packaging film 53 is evacuated from the suction hole. Is done. By sealing the opening of the packaging film 53, the cardboard tray 50 and the electronic component 54 are packaged.
[0027]
Since the article package B has a plurality of cardboards 52 each having a pocket 55 in which the electronic component 54 is accommodated, more electronic parts 54 than the article package A can be packaged. Therefore, if the article package B is used, the electronic components 54 can be shipped efficiently.
[0028]
As mentioned above, although embodiment of this invention was described, this invention is not limited to these, A various deformation | transformation is possible as described below.
[0029]
In the cardboard trays 10 and 50 in the above embodiment, double-sided cardboard is used for the cardboards 2 and 52, but the cardboard 2 and 52 may be single-sided cardboard. If the corrugated core paper in a single-sided cardboard is attached to the paper plates 1 and 51, the cross-sectional structure of the cardboard tray composed of the single-sided cardboard and the paper plates 1 and 51 is the cross-sectional structure of the cardboard trays 10 and 51. It becomes almost the same.
[0030]
In the above embodiment, the paper plates 1 and 51 in the cardboard trays 10 and 50 are made of cardboard. However, the present invention does not limit the paper plates 1 and 51 to cardboard. The paper plates 1 and 51 may be simple paper plates.
[0031]
In the corrugated cardboard tray 50 in the above embodiment, the paper board 51 and the corrugated cardboard 52 are alternately superposed, but only the plural cardboards 52 are superposed to deepen the pocket 55, and the superposed plural It is possible to stack the corrugated cardboard 52 on the upper surface of the paper plate 51. Since the pocket 55 is deep, a thick electronic component can be packaged.
[0032]
In the above embodiment, the electronic components 4 and 54 are fixed in the pockets 5 and 55. However, the article packaging bodies A and B of the present invention are not applied only to the electronic components 4 and 54, but other than the electronic components. This also applies to other parts.
[0033]
The present invention is not limited to the above, and various modifications can be made within the scope of the claims, and includes those in which each component is replaced with an equivalent.
