Description

Detailed Description of the Invention (Field of Application of the Invention) The present invention relates to an annular fluorescent lamp fixture having a shade in which an inverted bowl-shaped upper shade and a bowl-shaped lower shade are removably connected so that the whole has a spherical shape. This relates to packaging.

In this specification, the term "bowl-shaped" refers to a normal posture of the bowl that opens upward, and the term "inverted bowl-shaped" refers to a posture in which the bowl is turned upside down. Furthermore, the packaging body represents an assembly of an annular fluorescent lamp fixture and its packaging device.

(Background of the invention) An inverted bowl-shaped upper shade with a mounting hole in the center of the upper surface,
Shades, which are made by combining a bowl-shaped lower shade with an open hole in the center of the lower surface so that the whole has a spherical shape, are often used in Western-style annular fluorescent lamp fixtures. In such annular fluorescent lamp fixtures, not only the fixture body and the shade, but also the upper and lower shades can be separated as appropriate for assembly or packaging reasons.

When packaging, the device main body, upper shade, lower shade, etc., which can be separated from each other, are placed in a packaging box in an appropriate order, but in this case, the mutual arrangement of the upper shade and the lower shade is a problem. From the point of view of downsizing the packaging box, it is desirable to stack a bowl-shaped lower shade and an upper shade whose orientation has been changed so as to form a bowl shape, just like stacking bowls.

An example of a package in line with this purpose is
This is shown in Publication No. 161885. The contents will be briefly explained below using FIG. 40 in FIG. 6 is a packaging box, which contains a trapezoidal packing 50, a lower shade 30, an upper shade 20 whose vertical direction has been changed,
The instrument body 10 and the cylindrical packing 60 are stored in this order as shown in the figure. A part of the upper shade 20 is held between the trapezoidal packing 50 and the collar 11 of the instrument body 10.

On the other hand, the lower shade 30 is located in a wedge-shaped gap formed between the trapezoidal packing 50 and the upper shade 20. Specifically, a part of the lower shade 30 is inserted near the top of the wedge-shaped gap, but this is actually quite difficult. This lower shade 30 can be easily moved left and right so that the insertion becomes deeper or shallower. Further, with this movement, scratches occur on the upper shade 20 that is in contact with it.

(Object of the Invention) The present invention improves a part of the conventional packaging body in which the upper shade and the lower shade are stacked like one bowl and the other, so that the lower shade is difficult to move and the upper shade is This is to prevent any damage.

(Summary of the Invention) The packaging object of the present invention is an inverted bowl-shaped upper shade that has a mounting hole in the center of the upper surface and the peripheral edge of the mounting hole is supported by the brim of the instrument body, and the upper shade that has an open hole in the center of the lower surface. This is an annular fluorescent lamp fixture equipped with a bowl-shaped lower shade that is removably connected to the lamp so that the whole has a spherical shape. In particular, a stepped portion is provided near the peripheral edge of the attachment hole on the upper surface of the upper shade.

In the present invention, a trapezoidal packing having a raised piece on the periphery and a through hole in the center of the upper surface is arranged inside the bottom surface of the packaging box. Furthermore, do the following: The lower shade, which is separated from the upper shade and takes on a bowl shape when in use, is placed on the trapezoidal packing in the same position. The upper shade, which takes on an inverted bowl shape when in use, is placed on top of it in an upside-down position so as to take on a bowl shape. Furthermore, the instrument body is placed on top of it in an upside-down position compared to when in use, so that its head is inserted into the through-hole of the trapezoidal packing. Furthermore, a cylindrical gasket is placed so as to press the collar of the instrument body.

The peripheral edge of the attachment hole of the upper shield is sandwiched between the peripheral edge of the through hole of the trapezoidal packing and the collar of the instrument body. In this way, the upper shade inside the packaging box is fixed.

On the other hand, in the above state, the stepped portion in the upper shade faces the inner peripheral surface of the open hole and the upper surface of the periphery of the open hole in the lower shade. Therefore, the peripheral edge of the open hole of the lower shade is held between the trapezoidal packing and the step part of the upper shade. This also holds the lower shade inside the packaging box.

(Embodiment of the Invention) Hereinafter, an embodiment of the present invention shown in FIGS. 1 to 4 will be described. Note that the component numbers in FIG. 6 are quoted here as they are.

The main parts of the annular fluorescent lamp fixture to be packaged are the fixture body 10, the upper shade 20, and the lower shade 30. The main parts for packaging are a hexahedral packaging box 40, a trapezoidal packaging 50, and a cylindrical packaging 60.
