Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a shrunk package structure for lamps such as incandescent lamps and high-pressure metal vapor discharge lamps.

[0002]

[Prior Art]

 As shown in FIG. 4, the conventional packaging of a lamp is made up of an individual packaging box 1 made of corrugated cardboard for accommodating the lamp, and an outer packaging box 5 made of corrugated cardboard for accommodating a plurality of the individual packaging boxes 1. This method is generally widely used because it has sufficient strength and the packaging process is simple.

[0003]

[Problems to be solved by the device]

 The conventional packaging of the above-mentioned lamps has a drawback that the packaging cost is high because the individual packaging itself has a structure with a certain degree of strength and is further placed in an outer box. Therefore, there has been a demand for a packaging structure that has a simple structure for the interior and exterior to reduce packaging costs and has sufficient strength.

Further, the conventional packaging has a drawback that its water resistance is weak because the packaging material is mainly made of cardboard. For this reason, if the outer box or inner box contains moisture due to direct water splashing or moisture in the atmosphere penetrating, the strength of the packaging will weaken and the packaging box will be crushed and the internal lamp will be damaged or the internal box will be damaged. The metal part of the lamp stored in the room may be corroded. Also, if the packaging boxes contain moisture when they are stacked and stored high, the lower packaging box under load may be crushed and the stacked packaging boxes may collapse. However, adding a structure that is waterproof and moisture-proof to the conventional structure has not been generally performed because it leads to an increase in cost.

Further, in the conventional packaging, in order to arrange the lamps in a store or the like, it is necessary to open the outer box and take out the individual packaging boxes, and then rearrange them. Therefore, a packaging structure that can be easily taken out has been desired.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, in the present invention, a plurality of individual packaging boxes 1 containing lamps are placed on a bottom plate tray 2, and a top plate 3 is placed on the upper surface of the plurality of individual packaging boxes 1 placed. Then, the whole is covered with the shrink film 4 to be heat-shrinked to form a packaging structure. Here, the bottom plate tray 2 is a box-shaped tray made of corrugated board and having an open top surface and a shallow depth, and has a size that allows the individual packaging boxes 1 to be placed in an array and just accommodated. The top plate 3 is made of corrugated cardboard and has a square shape with four or more corners cut out or rounded, which is approximately the same size as or slightly larger than the upper surfaces of the plurality of individual packaging boxes 1 placed on the bottom plate tray 2. To the flat plate.

[0007]

[Action]

 In the packaging structure of the lamp configured as above, the exterior consists of a top plate, bottom plate tray and shrink film, so compared to conventional packaging using a corrugated cardboard box, the corrugated cardboard on the side and top lids overlaps each other. Material has been significantly reduced. Therefore, the cost of the packaging material is reduced and the weight is reduced.

Further, since the exterior of the side surface of the package is only the transparent shrink film, the label indicating the type of the content printed on the individual packaging box can be directly seen from the outside. Therefore, it is possible to identify the type of contents without printing the label on the outer box unlike the conventional packaging, and it is not necessary to print the label on the outer box. When the label indicating the product type of the contents is no longer printed on the exterior, if the lamps are housed in individual packaging boxes that fit exactly on the same bottom tray, even if they are different types, the lamps will be the same. Plates and bottom plates Can be packed using trays. The above will reduce the packaging process and also reduce the cost for label printing.

[0009] Also, the strength of the corrugated cardboard used for the individual packaging and the exterior is sharply reduced when it contains moisture. However, most of it is covered with a shrink film that is waterproof and moisture-proof. You can significantly prevent the ingress of water and moisture from.

Further, in shrink wrapping, the interior is fixed by utilizing the pressure applied toward the center of the wrapping due to the shrinkage of the shrink film, but by providing the top plate and the bottom plate tray as in the present invention, The force of sandwiching from both the top and bottom sides and the force of pressing the side surfaces are mainly acting, and the package is fixed while maintaining its rectangular shape without deforming. At this time, the top plate needs to be approximately the same size as or slightly larger than the upper surfaces of the individual packaging boxes.If the top panel is smaller than the upper surface, the top part of the individual packaging box protruding from the top plate shrinks. The film is deformed by the force applied when it is heat-shrinked, resulting in poor appearance, and if the deformation is severe, it may cause wobbling when the packages are stacked. After packaging, the top and bottom trays serve to protect the top and bottom and to enhance load bearing in the vertical direction.

In addition, when a flat plate having a rectangular shape is used without cutting the corners or rounding the shape of the top plate as in the present invention, the film positioned at the corner of the top plate when the shrink film is heat-shrinked is used. The film may break due to the higher tension applied to other parts. Therefore, if the top plate is shaped like a square with four corners cut out or rounded as in the present invention, a large tension is not applied to one point, and the film is less likely to break.

[0012] The strength of the packaging thus formed is that the plurality of individual packaging boxes are strongly fixed by the shrink film via the top plate and the bottom plate tray, and the strength of each individual packaging box is combined into one. It can be provided with strength and load resistance in the longitudinal direction.

Further, when the lamps thus packaged are taken out and arranged in a store, the individual packaging boxes are arranged on the tray only by breaking the shrink film, and it is not necessary to rearrange them.

[0014]

【Example】

 An embodiment of the present invention will be described with reference to FIG. The present embodiment is a case of packaging a high-pressure metal vapor discharge lamp, an individual packaging box 1 in which the high-pressure metallic vapor discharge lamp is stored, a bottom plate tray 2 for mounting the individual packaging box 1, and a bottom plate tray 2 It comprises a top plate 3 placed on the upper surface of the individual packaging box 1 placed on top, and a shrink film 4 covering the whole.

The bottom plate tray is made of corrugated cardboard and has a shallow depth, and is a box with a shallow depth, in which four individual packaging boxes are arranged in four rows and three rows in total. The top plate is also made of corrugated cardboard, and is a rectangular plate with four corners cut out, which is approximately the same size as the top surface of the 12 individual packaging boxes placed on the bottom plate tray. In this embodiment, the shrink film is made of polyethylene and has a thickness of 60 μm and a heat shrinkage temperature of about 140 to 150 ° C. The reason for using polyethylene is that even if holes are opened in the film, the holes do not spread easily even if they are opened during heat shrinkage or after packaging. This is because the toxic gas that can be maintained and that no harmful gas that is subject to domestic or foreign regulations is generated when waste is burned. (In polyvinyl chloride, holes are more likely to expand than in polyethylene, and chlorine gas is generated when incinerated.)

Further, the individual packaging box used in this embodiment will be described with reference to FIG. This is a box with an open top, with horizontal cuts in the top of a pair of side facing corners. The high-pressure metal vapor discharge lamp 6 is housed in the individual packaging box 1 with the base 8 facing upward. Then, the fixing member 7 for fixing the lamp is attached to the lamp 6. This fixing member 7 is a doughnut-shaped flat plate, and the hole in the center is larger than the diameter of the base and smaller than the diameter near the base of the outer bulb, so if you insert the base 8 into this hole, the fixing member will It stops near the boundary between the club and the outer sphere. The cut of the individual packaging box 1 is located slightly above the fixing member 8 when the lamp with the fixing member is stored in the individual packaging box, so that the lamp is fixed when the upper part of the cut is folded inward. .. Such individual packaging boxes are generally widely used because they are easy to wrap and have strength.

Next, the flow of the lamp packaging work according to this embodiment will be described step by step with reference to FIG. First, the lamps are stored in the individual packaging boxes 1, and 12 of them are arranged on the bottom tray 2 in four rows vertically and three rows horizontally. Then, the top plate 3 is placed on the upper surface of the individual packaging boxes arranged on this tray. (Fig. 2- (a), (b))

A strip-shaped shrink film 4 wider than the width of the package is wound around the package in this state, and after one round, the sheet is cut and joined to form a tubular shape. In this way, both ends of the tube are projected from the package by the same length. (Fig. 2- (c)) This protruding length is set appropriately in consideration of the shrinkage rate of the film.

The package in this state is placed in a furnace body in an atmosphere of a temperature of about 140 to 150 ° C. The shrink film begins to shrink due to heat, and the slack that is generated when the shrink film is wrapped gradually disappears. It In this state, take out from the furnace and finish the packaging work. (Fig. 2- (d)) Circular holes are left in both sides of the packaging body on the side where both openings of the shrink film cylinder before shrinkage were present in the packaging body thus formed. The size of this hole can be made larger or smaller to some extent depending on the length of the shrink film protruding from the package.

The load-bearing capacity of the packaging of this example, which was prepared as described above, showed almost the same strength as that of the conventional packaging, and it was confirmed that the packaging has sufficient strength as a lamp packaging. Also, it has been found that the cost can be about 90% that of conventional packaging.

In addition, the shape of the top plate was not cut out at the four corners as in the present embodiment, but the same packaging operation was performed using a top plate that was still in a square shape. The film at the corner of the top plate sometimes broke. Further, when the individual packaging boxes used in this example are arranged on the bottom plate tray in the same direction, two of the four corners of the top surface of the packaging have the folding parts of the individual packaging box, so that the rectangular packaging is used. With the top plate as it is, a space is formed under the corner portion of the top plate that comes to this position, so the top plate is folded toward the space side when the shrink is contracted, and the appearance is not preferable as compared with the present embodiment.

Although the present embodiment has been described by taking the packaging of 12 individual packaging boxes containing the high-pressure metal vapor discharge lamp as an example, it goes without saying that the types of lamps, the number of individual packaging boxes, etc., are other than the present exemplary embodiment. But it doesn't matter. Further, the type of shrink film may be other than the one used in this embodiment as long as certain conditions such as waterproofness, moisture resistance, difficulty in opening holes, and harmfulness at the time of disposal and combustion are provided. Also, the type of the individual packaging box may be other than that of this embodiment as long as it has a structure having a certain level of strength and load resistance in the vertical direction. Further, the same effect as that of the present embodiment can be obtained even if the top plate having a rectangular shape with four rounded corners is used.

[0023]

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects. By configuring the exterior with a top plate, bottom tray, and shrink film, the amount of corrugated board material on the side and the overlapping part of the lid is significantly reduced compared to the conventional exterior box, and the cost of packaging material can be reduced. Can be lightened. This also saves paper resources and is effective in terms of resource conservation.

Further, since only the shrink film having the side surface is transparent, the individual label printing can be directly seen from the outside, and the label printing indicating the kind of the content on the outer package is not necessary. As a result, it is possible to reduce the cost for printing the label on the conventional outer box. Also, if the lamps are housed in individual packaging boxes that fit exactly on the same bottom plate tray, the same top plate and bottom plate tray can be used for exterior packaging for different types of products, thus reducing the work process.

Further, since most of it is covered with the shrink film, the penetration of water and moisture into the packaging material is prevented. As a result, it is less likely that the strength of the packaging will deteriorate due to the presence of moisture and that the packaging boxes that have been stacked high during storage will collapse. In addition, corrosion of the metal part of the lamp is less likely to occur.

In addition, the size of the top plate is set to be the same as or slightly larger than the top surface of the individual packaging box, and the top plate is attached to the individual packaging box together with the bottom plate tray, so that the shape of the package does not lose its shape when the shrink film shrinks due to heat. In addition, since the top plate is notched or rounded at the corners, the film is less likely to be torn when the shrink film shrinks.

Further, since the bottom plate has a tray shape, it can be arranged at the store simply by removing the shrink film, which eliminates the conventional work of unpacking and taking out individual packaging boxes and arranging them.

Further, by mounting a top plate and a bottom plate tray on a plurality of individual packaging boxes and fixing them by heat shrink of the shrink sheet, the strength required for lamp packaging and the load-bearing capacity in the vertical direction are provided. be able to. By adopting the configuration of the present invention as described above, it is possible to provide a packaging form suitable for packaging the lamp.
