Conventional Example 2
Another packaging example is the packaging box device of Patent Document 1.
FIG. 24 is a developed view of the packaging box device, and FIG. 25 is an overall perspective view when two annular fluorescent lamps having different ring diameters are housed together.

  In the invention of Conventional Example 2, for example, when annular ring-shaped fluorescent lamps having different ring diameters are housed together, the locking provided by cutting into the surface that becomes the bottom of the packaging box device without using other members The annular fluorescent lamps are fixed by using the portion, and contact between the annular fluorescent lamps is prevented.

  The structure and manufacturing method of the packaging box device of Conventional Example 2 will be described.

  In FIG. 24, the packaging box device is constructed by assembling a plate body 910 made of a single sheet. The plate body 910 has a shape having a top surface portion 910a forming a box-shaped housing, a bottom surface portion 910b, side surface portions 911, 912, and insertion pieces 916 formed by extending each. The plate body 910 having such a shape is formed by processing a thick paper member such as pressing.

  On the other hand, a plurality of locking portions 913a, 913b, 914a, 914b, 915a, and 915b are provided in the vicinity of the center of the bottom surface portion 910b so as to be arranged around the virtual point A. These locking portions 913a to 915b are formed in a rectangular shape, for example. Further, two locking portions are arranged as a set and opposed to each other. In this case, the outer peripheral lines other than the opposing lines of the opposing rectangle are cut. That is, the plurality of locking portions 913a to 915b are part of the bottom surface portion 910b as shown in FIG. That is, the locking portions 913a to 915b can be easily formed simply by providing a cut in the bottom surface portion 910b. When the annular fluorescent lamp is stored, the plurality of locking portions 913a to 915b of the bottom surface portion 910b are bent in the storage side (inside) direction of the circular fluorescent lamp during or after the plate body 910 is assembled. Thus, the packaging box device is ready for use. That is, the plurality of locking portions 913a to 915b have a protruding shape in a storage chamber for storing the annular fluorescent lamp. In addition, annular annular fluorescent lamps (with a small ring diameter) having an outer diameter corresponding to the diameter with the inside of these engaging portions as contacts are accommodated inside the circumferentially arranged multiple engaging portions. On the other hand, an annular annular fluorescent lamp having an inner diameter having a diameter with the outside of the engaging portion as a contact is accommodated outside the engaging portion.

  The manufacturing method of a packaging box apparatus is performed using the above-mentioned plate body 910. First, as shown in FIG. 24, each surface is bent along a wavy line portion (folding curve) provided in the plate body 910. After that, as in the conventional packaging box device, the side surface portions 912 on both sides of the bottom surface portion 910b and the top surface portion 910a and the side surface portions 911 on both sides are respectively joined and fixed using an adhesive or an adhesive tape. To do. In this case, each coupling piece 911a extending from both side end portions of the side surface portion 911 is bonded to the surface inside the housing. In this way, a packaging box device is formed.

  Now, it is assumed that two annular annular fluorescent lamps having different annular diameters are accommodated and packaged. In this case, as shown in FIG. 25, the plurality of locking portions 913a to 915b provided on the bottom surface portion 910b are projected to the inside of the packaging box device. Then, after the ring-shaped fluorescent lamp 921 having a small ring diameter is housed inside the locking portions 913a to 915b, the ring-shaped fluorescent lamp 920 having a large ring diameter is housed. Thereafter, as described above, the side surface portion 911 and the side surface portion 912 are bonded to each other, and finally the insertion piece 916 is inserted into the packaging box device, thereby closing the opening and two annular ring-shaped fluorescent lights. Complete the packaging of the lamp. At this time, the ring-shaped fluorescent lamp 921 having a small ring diameter is securely fixed to the inside of the plurality of locking portions 913a to 915b, and at the same time, the ring-shaped fluorescent lamp 920 having a large ring diameter is similarly fixed to the locking portions 913a to 915b. Secured by the outside. That is, since the two ring-shaped fluorescent lamps 920 and 921 are securely fixed, the ring-shaped fluorescent lamp can be prevented from being damaged without coming into contact even when shaking or the like occurs during transportation.

  In addition, although the number of the locking portions is two and one set has been described as having three sets of locking portions, a plurality of more locking portions may be provided. In addition, the shape of these locking portions is not limited to a rectangle, but may be a trapezoidal shape, for example, and any shape as long as it can securely lock an annular fluorescent lamp. good. Furthermore, the plurality of locking portions may be provided by changing the length of the locking portion and the arranged circle diameter according to the ring diameter of the annular annular fluorescent lamp to be housed.

JP-A-8-183511

The ring-shaped fluorescent lamp packaging described with reference to FIG. 22 of the conventional example 1 requires time and effort to insert the cushion 801 between the ring-shaped fluorescent lamp 30 and the ring-shaped fluorescent lamp 32, and the set 802 is stored in the individual packaging box 803. There was also a trouble to do. In addition, there is a problem that the cost for generating the individual packaging box 803 is high.
In addition, since the packaging of the annular fluorescent lamp described with reference to FIG. 23 of the conventional example 1 has a structure in which a partition plate 805 is inserted for each annular fluorescent lamp, the number of annular fluorescent lamps that can be stored in one outer box. Has a problem that it is less than the packaging structure of FIG. The laminated annular fluorescent lamps are not brought into contact with each other by the partition plate 805. However, when the outer box 11 vibrates after being housed in the outer box 11, the annular fluorescent lamp 30 also vibrates and the annular fluorescent lamp 30 is damaged. There was a problem that there was a risk of doing.

  Moreover, in the packaging in the prior art example 2, after setting the annular fluorescent lamps 920 and 921 on the bottom surface portion 910b, there is a trouble of assembling the box. Moreover, since the latching | locking parts 913a-915b are one set, and two latching parts accommodate the ring-shaped fluorescent lamp which has an outer diameter according to the diameter which makes the inner side of a latching part a contact, When the shapes and positions of the two locking portions are slightly shifted, there is a problem that only one locking portion comes into contact with the annular fluorescent lamp and the annular fluorescent lamp cannot be fixed securely. In addition, since the annular fluorescent lamp having an inner diameter corresponding to the diameter with the outside of the engaging portion as a contact point is accommodated, if the shape and position of the two engaging portions are slightly shifted, only one engaging portion has the annular fluorescent lamp. There is a problem that the ring-shaped fluorescent lamp cannot be reliably fixed in contact with the lamp.

For this reason, this invention aims at the following.
The packaging structure for packaging the annular fluorescent lamp is simplified, and the cost for producing the package is reduced. In addition, the annular fluorescent lamp is set so as to be securely fixed so that the annular fluorescent lamp does not vibrate even when the package is vibrated. In addition, a large number of annular fluorescent lamps can be packaged with a small package.

The holding plate of the annular fluorescent lamp according to the present invention,
A mounting plate for mounting the annular fluorescent lamp;
A plurality of projections provided on a line connecting two points on the same circumference on the surface of the mounting plate, and holding the ring-shaped fluorescent lamp from the surface of the mounting plate;
The protrusion has a cutout tongue formed by cutting and bending a part of the mounting plate as a bending line that connects two points on the same circumference,
The cutout tongue has a trapezoidal shape, and the protrusion is formed by folding the cutout tongue in the outer direction of the circumference, and holds the inner peripheral side surface of the annular fluorescent lamp at four points. And

The holding plate of the annular fluorescent lamp according to the present invention,
A mounting plate for mounting the annular fluorescent lamp;
A plurality of projections provided on a line connecting two points on the same circumference on the surface of the mounting plate, and holding the ring-shaped fluorescent lamp from the surface of the mounting plate;
The protrusion has a cutout tongue formed by cutting and bending a part of the mounting plate as a bending line that connects two points on the same circumference,
The protrusion is formed by folding the cut-out tongue part in the outward direction of the circumference, and the protrusion on the tip side is more than the protrusion on the placing plate side described above with the two-fold bent part as a boundary. The width is small, and the inner peripheral side surface of the annular fluorescent lamp is held at four points.

  The packaging structure of the annular fluorescent lamp according to the present invention is characterized in that a plurality of retaining plates of the annular fluorescent lamp are packaged side by side in a direction perpendicular to the surface of the mounting plate.

And the flat plate 10 has the notch part 40 which notched a part of circumference | surroundings. The notch 40 is a part that is put on when the flat plate 10 is taken out from the outer box that houses the stacked flat plates 10. 14a, 14b, and 14c are trapezoidal protrusions inscribed in the circle B13, and are provided on a line connecting two points 13a and 13b on the circumference of the circle B13. On the other hand, 15a, 15b, and 15c are trapezoidal protrusions inscribed in the circle A12, and are provided on a line connecting two points 12a and 12b on the circumference of the circle A12. The circle A12 and the circle B13 have different radii rA and rB, and the size of the radius is rA> rB.
FIG. 2 is a view showing a state in which the protrusion shown in FIG. 1 is cut by partially cutting a flat plate.
In FIG. 2, 10a is a surface on which the annular fluorescent lamp of the flat plate 10 is mounted. Other reference numerals are the same as those in FIG.
FIG. 3 is a diagram showing a state in which the bent protrusion of FIG. 2 is further folded in two.
FIG. 4 is an enlarged view of one of the protrusions shown in FIG. Although FIG. 4 shows an enlarged view of the protrusion 15b as a representative of the protrusion, the other protrusions 15a and 15c and the protrusions 14a to 14c have the same shape as the protrusion 15b, and are indicated by reference numerals. It shall have the same element as the element.
5 and 6 are views showing a progress state until the protrusion 15b of FIG. 4 reaches the state of FIG.

The protrusion 15b in FIG. 4 includes a fold line 20 at a part of a straight line connecting the points 12a and 12b on the circumference of the circle A12, and further includes a fold line 24 that folds the protrusion 15b in half. . Further, it has a cut portion 22. The protrusion 15b has a structure in which a line indicated by a bold line in FIG. 4 is cut from the flat plate 10 (that is, the protrusion 15b has only the folding line 20 connected to the flat plate 10).
5A, the protrusion 15b obtained by cutting the line indicated by the bold line in FIG. 4 is folded by folding the folding line 20, and the protrusion 15b is substantially perpendicular to the flat plate 10 as shown in FIG. This shows the state. The annular fluorescent lamp is mounted on the surface where the protrusions 15 b are substantially perpendicular to the flat plate 10. Although the protrusion 15b is also a cut-out tongue, the name “projection” will be described in a unified manner. FIG. 5A is a front view of the protrusion 15b as viewed from the inside of the circle A12. FIG. 5B is a perspective view of the protrusion 15b of FIG. As can be seen from FIG. 5B, the cut portion 22 protrudes from the folding line 20. FIG. 5C is a front view of FIG. 5A viewed from the outside of the circle A12. As is clear from FIG. 5C, the cut portion 22 protrudes from the flat plate 10 to the surface opposite to the surface 10a having the protrusions. FIG. 5D is a view of the protrusion 15b of FIG. 5A as viewed from above. As can be seen from FIG. 5D, when the projection 15b is folded along the folding line 20, the cut portion 22 protrudes from the flat plate 10 as shown in FIGS. 5B and 5C. For this reason, a gap is formed at the position where the cut portion 22 is originally cut after the cut portion 22 is present. The gap is a tongue end insertion port 26 into which the tip of the protrusion 15b is inserted.
FIG. 6A is a view in which the protrusion 15b in the state of FIG. 5A is folded in a folding line 24, and the bent protrusion 15b is a front view as viewed from the inside of the circle A12. . FIG. 6B is a perspective view of the protrusion 15b in the state of FIG. As can be seen from FIG. 6B, the projection 15b is folded along the folding line 24 so that the projection 15b is bent toward the outside of the circle A12. It has a stacked structure. FIG. 6C is a front view of the protrusion 15b of FIG. 6A viewed from the outside of the circle A12. FIG. 6C shows that the tip of the bent projection 15 b is inserted into the tongue end insertion port 26. FIG. 6D is a top view of the protrusion 15b shown in FIG. 6C. As can be seen from FIG. 6D, the tip of the projection 15b is inserted into the tongue end insertion port 26, and the tongue end insertion port 26 is blocked.
As shown in FIG. 5, when the protrusions 15a to 15c and the protrusions 14a to 14c are assembled, it becomes as shown in FIG. 2, and as shown in FIG. 6, the protrusions 15a to 15c and the protrusions 14a to 14c are assembled. And as shown in FIG.

FIG. 7 is a diagram showing an example in which three annular fluorescent lamps having different diameters (ring diameters) around the inside of the annular fluorescent lamp are mounted on the surface 10a of the flat plate 10 shown in FIG.
In FIG. 7, 30, 32, and 34 are annular fluorescent lamps, and the relationship between the sizes of the diameters is 30 <32 <34. 10 b is a surface opposite to the surface 10 a of the flat plate 10. 8A and 8B are diagrams showing dimensions of a commercially available ring fluorescent lamp.
In FIG. 8A, B is the outer diameter of the annular fluorescent lamp, A is the inner diameter (ring diameter) of the annular fluorescent lamp, and D is the tube diameter of the annular fluorescent lamp.
In FIG. 8B, the type “FCL40 / 38” corresponds to the annular fluorescent lamp 30 in FIG. 7, the type “FCL32 / 30” corresponds to the annular fluorescent lamp 32 in FIG. 7, and the type “FLC30 / "28" corresponds to the annular fluorescent lamp 34 of FIG.
FIG. 9 is a diagram in which dimensions are added to the flat plate 10 shown in FIG.
FIG. 10 is an enlarged view of a part of the flat plate 10 on which the annular fluorescent lamp shown in FIG. 7 is mounted.
As shown in FIG. 10, the annular fluorescent lamp 34 is mounted on the flat plate 10 so as to be held inside the protrusions 14a and 14c. The annular fluorescent lamp 32 is mounted on the flat plate 10 so as to be held outside the protrusions 14a and 14c and inside the protrusion 15a, that is, between the protrusions 14a and 14c and the protrusion 15a. ing. The annular fluorescent lamp 30 is mounted on the flat plate 10 so as to be held outside the protrusion 15a.

It will be described that the annular fluorescent lamp 30, the annular fluorescent lamp 32, and the annular fluorescent lamp 34 are mounted on the flat plate 10 as shown in FIGS. 7 and 10 using the dimensions shown in FIGS.
According to FIG. 8B, the dimension D is a dimension common to the annular fluorescent lamp 30, the annular fluorescent lamp 32, and the annular fluorescent lamp 34, and is 33 mm at the maximum. The dimension B is 381 mm for the annular fluorescent lamp 30, 307 mm for the annular fluorescent lamp 32, and 233 mm for the annular fluorescent lamp 34. The dimension A is 315 mm as a standard value for the annular fluorescent lamp 30, 241 mm as a standard value for the annular fluorescent lamp 32, and 167 mm as a standard value for the annular fluorescent lamp 34. The flat plate 10 shown in FIG. 9 assumes that the annular fluorescent lamp 30, the annular fluorescent lamp 32, and the annular fluorescent lamp 34 having the dimensions shown in FIG. 8 are mounted, and the protrusions 15a to 15c inscribed with the circle A and the circle B The dimensions of the protrusions 14a to 14c that are inscribed with each other are the dimensions shown in FIG. Details of the dimensions shown in FIG. 9 will be described below.

The flat plate 10 shown in FIG. 9 has six protrusions 15a to 15c inscribed with the circle A and protrusions 14a to 14c inscribed with the circle B. The six protrusions are installed such that the center line of each protrusion has an angle of 60 degrees with the center line of the adjacent protrusion. Each protrusion has a width of 20 mm at the tip of the protrusion inserted into the tongue end insertion port 26. Further, since the width of the cut portion 22 is 25 mm, the width of the tongue end insertion port 26 is also 25 mm. For this reason, the tip of the protrusion having a width of 20 mm inserted into the tongue end insertion port 26 can be easily inserted into the tongue end insertion port 26. The bend line 20 has a width of 17.5 mm. Further, since the height of the cut portion 22 is 4 mm, the height of the tongue end insertion port 26 is 4 mm. If the thickness of the plate forming the flat plate 10 is about 2 mm, the tip of the protrusion is inserted into the tongue end. The operation of inserting into the mouth 26 can be performed smoothly. The protrusions 14a to 14c inscribed in the circle B having a diameter smaller than the circle A have a length h1 from the center point of the circle B to the tip of the protrusion of 44 mm, and the length from the tip of the protrusion to the folding line 20 The length h2 is 40 mm, and the length h3 from the fold line 24 to the fold line 20 is 34 mm. Since the difference between the length (h2) from the tip of the projection to the fold line 24 and the length h3 from the fold line 24 to the fold line 20 is 40 mm-34 mm and 6 mm, the fold line 24 is folded. In this case, the tip of the protrusion can be inserted into the tongue end insertion port 26 by 6 mm. For this reason, it can be considered that the tip of the protrusion inserted into the tongue end insertion port 26 having a height of 4 mm is difficult to come off. When the projections 14a to 14c inscribed in the circle B are in the state shown in FIG. 3, the length from the center point of the circle B to the projection standing substantially perpendicular to the flat plate 10 is 44 mm (h1 ) +40 mm (h2) +34 mm (h3), it can be seen that it is 118 mm. For this reason, the dimension of the ring-shaped fluorescent lamp that can be mounted on the flat plate 10 so as to be located inside the protrusions 14a to 14c inscribed in the circle B is a ring-shaped fluorescent lamp in which the dimension B is smaller than 118 mm × 2 = 236 mm. As shown in FIG. 8B, the annular fluorescent lamp having a dimension B of 236 mm or less is an annular fluorescent lamp 34. Therefore, the annular fluorescent lamp 34 can be mounted on the flat plate 10 so as to be held inside the protrusions 14a to 14c inscribed in the circle B as shown in FIGS. In addition, since the dimension “FCL20 / 18” in FIG. 8B has a dimension B of 213 mm, it can be mounted on the flat plate 10 so as to be held inside the protrusions 14a to 14c inscribed in the circle B. is there.
In addition, 15a to 15b in FIG. 9 has a length from the center point of the circle A to the tip of the projection of xmm, and other dimensions are the same as the projections 14a to 14c inscribed in the circle B described above. It is. The dimension x is determined and determined as follows. Note that the center points of the circle A and the circle B are the same.
Consider a case where the annular fluorescent lamp is mounted on the flat plate 10 so as to be sandwiched and held between the protrusions 15a to 15c inscribed with the circle A and the protrusions 14a to 14c inscribed with the circle B. Since the dimension D of the annular fluorescent lamp used in the first embodiment is 33 mm at the maximum from FIG. 8B, the protrusions 15a to 15c inscribed in the circle A and the protrusions 14a to 14c inscribed in the circle B Between, a ring-shaped fluorescent lamp can be mounted as long as it is 33 mm or more. The flat plate 10 has a square shape with a side of 380 mm. The center point of the circle A12 and the circle B13 (see FIG. 1 for the circle A12 and the circle B1) is also the square center point of the flat plate 10. The protrusions 15a to 15c are designed so that the length from the center point of the circle A to the end of the notch 22 falls within a length of 190 mm, which is 380 mm / 2. Further, the circular fluorescent lamp is mounted on the flat plate 10 so as to hold the circular fluorescent lamp outside the protrusions 15a to 15c, but the dimension y in FIG. 9 is such that the circular fluorescent lamp is completely mounted on the flat plate 10. A length equal to or longer than the dimension D is required. Since the dimension D is a maximum of 33 mm from FIG. 8B, the dimension y needs to be at least 33 mm. The dimensions of the protrusions 15a to 15c are exactly the same as the dimensions of the protrusions 14a to 14c except for the dimension x. For this reason, the total of dimensions other than the dimension x is 40 mm (h2) +34 mm (h3) +33 mm (y) = 107 mm. Further, since the annular fluorescent lamp is mounted so as to be sandwiched between the protrusions 14a to 14c inscribed with the circle B and the protrusions 15a to 15c inscribed with the circle A, the protrusions 15a to 15c inscribed with the circle A are It must be at least 33 mm away from the center point of the circle A (circle B) than the protrusions 14a to 14c inscribed in B. That is, the difference in radius between the circle A and the circle B is at least 33 mm, and the dimension x of the protrusions 15a to 15c may be 44 mm (h1) +33 mm = 77 mm or more. However, since the protrusions 15a to 15c are designed so that the length from the center point of the circle A to the end of the notch 22 falls within a length of 157 mm, which is 380 mm / 2-33 mm (y). When x + 40 mm + 34 mm ≦ 157 mm and the dimension x ≧ 77 mm, the dimension x is 83 mm at the maximum and 77 mm at the minimum.
As described above, since the dimension x is 77 mm or more and 83 mm or less, in the first embodiment, the dimension x is 80 mm. When the dimension x is 80 mm, the annular fluorescent lamp held so as to be sandwiched between the protrusions 14 a to 14 c inscribed with the circle B and the protrusions 15 a to 15 c inscribed with the circle A has a dimension A of 118 mm (44 mm (h1 ) +40 mm (h2) +34 mm (h3)) × 2 = 236 mm or more, and dimension B must be a ring-shaped fluorescent lamp having a size of 152 mm (80 mm (x) +40 mm (h2) +34 mm (h3)) × 2 = 308 mm or less .
From FIG. 8B, the annular fluorescent lamp satisfying the above dimensions is an annular fluorescent lamp 32 having a standard value of dimension A of 241 mm and a maximum value of dimension B of 307 mm. Further, the dimension B of the annular fluorescent lamp mounted on the flat plate 10 so as to be held outside the protrusions 15a to 15c inscribed in the circle A is (80 mm (x) +40 mm (h2) +34 mm (h3)) × 2. Since it is equal to or greater than 308 mm, the annular fluorescent lamp arranged on the outermost side is the annular fluorescent lamp 30 from FIG.

Next, using the protrusion 14a as an example, how the annular fluorescent lamp 32 mounted on the flat plate 10 is held by the protrusion 14a will be described with reference to the drawings.
FIG. 11A is a view showing a state in which the bending line 24 is folded and the tip end portion of the protrusion 14 a is inserted into the tongue end insertion port 26. FIG. 11B is a cross-sectional view taken along the line AA in FIG. As shown in FIG. 11B, the annular fluorescent lamp 32 is in contact with and held by the protrusion 14a and the four points of point a, point b, point c, and point d. The annular fluorescent lamp 921 and the engaging portions 13a and 13b described in the conventional example 2 are in contact with each other at one point. That is, two points of the set of locking portions are in contact with the annular fluorescent lamp. For this reason, the flat plate 10 having the protrusions that hold the annular fluorescent lamp at the four contact points has a stronger force to hold the annular fluorescent lamp than in the conventional example 2, and after the annular fluorescent lamp is mounted on the flat plate 10, the flat plate 10. Even if it vibrates, the effect of preventing the annular fluorescent lamp from vibrating is greater.

As described above, in Embodiment 1, the annular fluorescent lamp holding plate is characterized in that the annular fluorescent lamp is held by the protrusion provided on the circumference having the center point on the flat plate as the holding plate. Went. In addition, the side connecting the two points inscribed inwardly extends from the circumference to the center, the side connecting the two inscribed points is a polygonal line, and the other three points are trapezoidal cuts and cutouts integrated with a flat plate made of cut lines The holding plate of the annular fluorescent lamp is described. In addition, a description has been given of a holding plate for an annular fluorescent lamp that holds an annular fluorescent lamp by a plurality of protrusions provided on concentric circles. In addition, a description has been given of a holding plate for holding ring-shaped fluorescent lamps having different ring diameters by arranging a plurality of protrusions inscribed in concentric circles having different radii at different positions.
In addition, the holding plate for holding the protrusion for holding the annular fluorescent lamp at the holding points consisting of four points by folding the trapezoidal protrusion in the outward direction from the center has been described.

Embodiment 2. FIG.
In the first embodiment described above, an example of the protrusion that has been folded along the folding line 24 of the trapezoidal protrusion has been described. In the second embodiment, an example will be described in which the cutout tongue is formed without bending the protrusion into two.
FIG. 12 is a diagram illustrating an example of a holding plate including the protrusions in the second embodiment. In FIG. 12, 115a to 115c and 114a to 114c are protrusions. 115a to 115c in FIG. 12 are similar to the protrusions 15a to 15c inscribed in the circle A12 in FIG. 2 except that the protrusions 15a to 15c are not bent in two. The dimension is set to 33 mm or more so as to be larger than the maximum value of the dimension D which is the tube diameter of the annular fluorescent lamp mounted on (the dimension D is a maximum of 33 mm from FIG. 8A). 12 are similar to the protrusions 14a to 14c inscribed in the circle B13 in FIG. 2, except that the protrusions 114a to 114c are not folded in two. Similarly to the protrusions 115a to 115c, the protrusions 114a to 114c have a height of 33 mm or more so as to be larger than the maximum value of the dimension D. As in FIG. 7 of the first embodiment, the flat plate 10 shown in FIG. 12 can be mounted with three ring fluorescent lamps having different diameters. However, since the projections 115a to 115c and 114a to 114c shown in FIG. 12 have a structure that is not bent in two, there are two points where each projection comes into contact when the annular fluorescent lamp is mounted. It is conceivable that the holding force is somewhat less than that of the protrusion described in 1. However, since the structure of the protrusion is made easier, the process of forming the holding plate is easier than the flat plate described in the first embodiment.

12 has a trapezoidal shape in which the thick side is integrated with the flat plate 10 and the other sides are separated from the flat plate 10. FIG. However, it may be a protrusion having an inverted trapezoidal shape. In the inverted trapezoid, the narrow side is integrated with the flat plate 10 and the other side is separated from the flat plate 10. An image obtained by rotating the trapezoidal projection shown in FIG. 12 by 180 degrees is the shape of the inverted trapezoidal projection.
When the annular fluorescent lamp is mounted on the flat plate 10 having the inverted trapezoidal projection, there are two points where the projection and the annular fluorescent lamp are in contact. However, when the annular fluorescent lamp mounted on the flat plate 10 is to be removed from the projection, the width of the projection increases toward the direction in which the annular fluorescent lamp is to be removed. For this reason, it is considered that the annular fluorescent lamp is less likely to come off than the protrusion, and even if the protrusion has a structure that is not bent in two, the effect of making it difficult to remove the annular fluorescent lamp mounted on the flat plate 10 is considered sufficient.

Embodiment 3 FIG.
In the third embodiment, the trapezoidal protrusion described in the first embodiment and the protrusion having a different shape from the inverted trapezoidal protrusion described in the second embodiment will be described.
FIG. 13 is a diagram illustrating an example of a protrusion in the third embodiment. FIG. 13A is a diagram illustrating an example of a protrusion having another shape. In FIG. 13A, reference numeral 16 denotes a protrusion, which is a protrusion having a shape in which two convex lenses are combined vertically. Reference numeral 161 denotes a fold line. Reference numeral 162 denotes a cut portion, and 163 denotes a plug portion. Reference numeral 164 denotes a fold line. The protrusion described in the third embodiment is different from the protrusion described in the first embodiment only in its shape, and is provided on a line connecting two points on the same circumference on the surface of the flat plate. And it shall be the same as the said Embodiment 1 in the point which folds a part of protrusion and forms a cut-out tongue part. In FIG. 13B, the folding line 164 is folded so that the projection 16 is substantially perpendicular to the flat plate 10, and the folding line 161 is folded in the state where the projection 16 is folded inside. It is the front view seen from the outside of the circle which touches. When the fold line 164 is folded, the notch 162 is retracted to the lower side of the flat plate 10, and a gap like the tongue end insertion port 26 of FIG. The fold line 161 is folded and the insertion part 163 is inserted into the gap. FIG. 13C is a cross-sectional view taken along the line BB in FIG. In FIG. 13C, the annular fluorescent lamp 36 is mounted on the flat plate 10 so as to be held outside the projection. In the annular fluorescent lamp 36, the two points 16 a and 16 b of the protrusion 16 are in contact with the protrusion 16. There are two points where the annular fluorescent lamp 36 and the protrusion 16 contact each other. However, since the width of the protrusion 16 increases in the direction of removing the annular fluorescent lamp 36 mounted on the flat plate 10, the annular fluorescent lamp 36. It is conceivable that it is difficult to be separated from the protrusion 16. Thus, the protrusion 16 may have a shape in which two convex lenses are connected vertically as shown in FIG.

  Further, the protrusion may have a shape as shown in FIG. In FIG. 14A, reference numeral 18 denotes a protrusion, and as shown in FIG. 13A, it is a shape in which two protrusions in the shape of a convex lens are vertically stacked. A feature is that the protrusions 182 have a smaller width. 183 is a fold line, 185 is also a fold line, and 184 is a notch. FIG. 14B is a front view of the protrusion 18 viewed from the outside of a circle formed by folding the convex lens-type protrusion 181 along the folding line 183. When the fold line 185 is folded and folded so that the projection 18 is substantially perpendicular to the flat plate 10, the cut portion 184 is retracted to the lower side of the flat plate 10, and the flat plate 10 is moved to FIG. A gap like a tongue end insertion opening 26 is formed. FIG. 14B is a diagram in which the tip of the convex lens type protrusion 181 is inserted into the gap. The convex lens-type protrusion 181 needs to be slightly higher than the convex lens-type protrusion 182 in order to insert its tip into the insertion slot, and therefore has a relationship of h1 <h2. FIG. 14C is a sectional view taken along the line CC in FIG. When the annular fluorescent lamp 36 is mounted on the flat plate 10 so as to be held outside the protrusion 18, the annular fluorescent lamp 36 and the protrusion 18 are in contact with each other at four points of points 18a, 18b, 18c and 18c. For this reason, two points more than the protrusion 16 shown in FIG. 13 are in contact with the annular fluorescent lamp 36, so that the holding power can be further increased.

  As described above, the shape of the protrusion is not limited to a trapezoid or an inverted trapezoid, and may be a protrusion having a shape as described in the third embodiment.

Embodiment 4 FIG.
One example of the protrusion described in the first to third embodiments is provided so as to be inscribed on a line connecting two points on the circumference. In the fourth embodiment, an example of a protrusion circumscribing a circle on the surface of a flat plate will be described.
FIG. 15 is a diagram illustrating an example of a flat plate having protrusions circumscribing a circle in the fourth embodiment.
In FIG. 15, the protrusions 15 a to 15 c are protrusions that are inscribed at two points of the circle A <b> 12 and the contact 12 a and the contact 12 b shown in FIG. 1. Reference numerals 214a to 214c are projections circumscribing the circle B13 and the points 13a and 13b. Reference numerals 214a to 214c have inverted trapezoidal shapes, and are similar to the inverted trapezoidal projections 114a to 114c shown in FIG. 12 of the third embodiment. The protrusions 214 a to 214 c are separated from the flat plate 10 at the sides indicated by solid lines, and the lines indicated by dotted lines are folded so that the protrusions 214 a to 214 c are substantially perpendicular to the flat plate 10. The protrusions 214a to 214c can hold the annular fluorescent lamp on the inner side and the outer side.

An example of a protrusion having a different shape that circumscribes the circle will be described.
FIG. 16 is a diagram illustrating an example of a protrusion circumscribing a circle in the fourth embodiment.
In FIG. 16, the protrusions 15a to 15c inscribed in the circle A12 are the same protrusions as the protrusions 15a to 15c inscribed in the circle A12 shown in the first embodiment. 314a to 314c are projections circumscribing the circle B13, and the circle B13, the point 13a, and the point 13b are in contact with each other. The protrusions 314a to 314c have an inverted trapezoidal shape like the protrusions 214a to 214c in FIG. However, after the protrusions 314a to 314c are separated from the flat plate 10 at sides other than the fold line 320, the fold line 320 is folded so that the protrusions 314a to 314c are substantially perpendicular to the flat plate 10. Further, the folding line 324 is folded so that the four points of the protrusions can contact and hold the annular fluorescent lamp like the protrusions 14a to 14c of the first embodiment (implementation). 11B of the first embodiment includes a diagram for explaining that the four points a, b, c, and d of the protrusion 14a are in contact with and held by the annular fluorescent lamp 32). Further, the cut portion 322 is retracted to the lower side of the flat plate 10 by folding the fold line 320, so that an insertion port such as the tongue end insertion port 26 of FIG. The fold line 324 is folded toward the inside of the circle B13, and the insertion portion 323 is inserted into the insertion opening. The front view which looked at the protrusion 314b when the insertion part 323 was inserted in the insertion port in FIG. 17 from the inner side of the circle | round | yen is shown. When the projection 314a to 314c is mounted on the flat plate 10 so as to hold the annular fluorescent lamp outside the circumscribed circle B13, as shown in FIG. 11 of the first embodiment, the annular fluorescence lamp and the projections 314a to 314c. Touches at four points. For this reason, the ring-shaped fluorescent lamp held by the four points in one protrusion is difficult to come off. Moreover, it becomes difficult to vibrate.

  Further, in FIG. 15 and FIG. 16, the example in which the protrusions inscribed in the circle A12 and the protrusions inscribed in the circle B13 are mixed in one flat plate 10 has been described. However, as shown in FIG. 18, it may be a flat plate 10 having protrusions circumscribing the circle A12 and the circle B13. 18, protrusions 214a to 214c are the same as the protrusions 214a to 214c of FIG. 15, and 215a is a protrusion that circumscribes the circle A12. The protrusions 215a to 215c are in contact with the circle A12 at two points of points 12a and 12b. The projections 215 a to 215 c are separated from the flat plate 10 at sides other than the folding line 220, and the folding line 220 is folded so that the projections 215 a to 215 c are substantially perpendicular to the flat plate 10. Each of the protrusions 215a to 215c has an inverted trapezoidal shape, and when the annular fluorescent lamp mounted on the flat plate 10 is moved in the direction to be removed, each of the protrusions 215a to 215c comes into contact with the annular fluorescent lamp. Since the width of the protrusion is wider in the direction in which the annular fluorescent lamp moves than the point where the annular fluorescent lamp moves, the structure is such that the annular fluorescent lamp is difficult to remove.

  In FIG. 18, the protrusion having a structure in which the protrusion is not bent in two has been described. However, the protrusion may be bent in two as shown in FIG. 9. In FIG. 19, 314a to 314c are the same protrusions as the protrusions 314a to 314c of FIG. 16, and 315a to 315c are protrusions circumscribing the circle A12 at points 12a and 12b. The protrusions 315a to 315c are protrusions having the same shape as the protrusions 314a to 314c. As described above, the annular fluorescent lamp can be held even with the flat plate 10 having the protrusions structured to be folded in two so as to circumscribe the circle.

Embodiment 5 FIG.
The flat plate 10 having the protrusions described in the first embodiment has protrusions on one side of the flat plate 10 as shown in FIG. 7, and the annular fluorescent lamp is mounted on the surface having the protrusions to hold the circular fluorescent lamp. Explained the example. However, the protrusions can be provided on both surfaces of the flat plate 10. In the fifth embodiment, an example in which protrusions are provided on both surfaces of the flat plate 10 and the annular fluorescent lamp is held on both surfaces of the flat plate 10 will be described.

  FIG. 20 is a diagram illustrating an example in which there are protrusions on both surfaces of the flat plate 10. In FIG. 20, the flat plate 10 has a protrusion 15a on one surface and a protrusion 415a on another surface. The protrusion 15a and the protrusion 415a are the same protrusions as the protrusion 15a in the first embodiment. In FIG. 20, the flat plate 10 is illustrated as having one protrusion on each surface, but as illustrated in FIG. 3, the flat plate 10 has protrusions 15 a to 15 a that are inscribed with the circle A on one surface. It is assumed that six protrusions 14a to 14c inscribed with 15c and circle B are provided, and six protrusions 415a to 415c and protrusions 414a to 414c are provided on the other surface. The protrusions 415a to 415c are the same protrusions as the protrusions 15a to 15c inscribed in the circle A, and the protrusions 414a to 414c are the same protrusions as the protrusions 14a to 14c inscribed in the circle B. The flat plate 10 having protrusions on both surfaces can be mounted with three ring fluorescent lamps having different diameters on each surface, and one flat plate 10 can be mounted with a total of six ring fluorescent lamps. A flat plate 10 on which six annular fluorescent lamps are mounted is inserted and packed in the x direction of the box 11.

  Thus, the flat plate 10 can have protrusions on both sides as well as on one side. By providing protrusions on both sides, the number of annular fluorescent lamps that can be held by one flat plate can be increased.

Embodiment 6 FIG.
In the sixth embodiment, an example of a packaging structure of an annular fluorescent lamp will be described.
FIG. 21 is a diagram illustrating an example of a packaging structure of an annular fluorescent lamp. In FIG. 21, the flat plate 10 on which three ring fluorescent lamps having different diameters are mounted is set as one set, and the flat plates 10 a to 10 i are set in the same set as the flat plate 10. The flat plates 10, 10a to 10i are stacked and inserted into the box 11 in the x direction and packed. A plurality of sets can be packed in one box by forming the flat plate 10 on which the annular fluorescent lamp is mounted in a laminated structure. Further, the protrusion provided on the flat plate 10 has a height of the protrusion so that the annular fluorescent lamp does not directly contact the flat plate 10 immediately above when the flat plate 10 on which the circular fluorescent lamp is mounted has a laminated structure. It is designed to be slightly larger than the tube diameter. The height H in FIG. 11A is designed to be slightly larger than the tube diameter of the annular fluorescent lamp. For example, according to FIG. 8, the dimension D is a maximum of 33 mm. According to FIG. 9, the height h3 is 34 mm, which is designed to be 1 mm larger than the maximum tube diameter of the annular fluorescent lamp. For this reason, even if the flat plate 10 on which the annular fluorescent lamp is mounted as shown in FIG. 21 has a laminated structure, the projections 15a to 15c and the projections 14a to 14c support the flat plate 10 immediately above, so that the annular fluorescent lamp is directly laminated. There is no contact with the flat plate 10 formed. For this reason, there is no possibility that the annular fluorescent lamp contacts the flat plate 10 and is damaged due to pressure.

Further, in FIG. 21, a plurality of sets are stacked one on top of the other, but a plurality of sets can be stacked on the left and right and packed in the box 11.
Further, the flat plate 10 may be replaced with the bottom surface portion 910b of FIG. 24 of the conventional example 2, and a side surface portion and an upper surface portion may be attached around the flat plate 10 to form a box-shaped packaging structure.
Further, the mounting plate is not necessarily a flat plate. For example, in the annular fluorescent lamp described in the first to fifth embodiments, when the annular fluorescent lamp is mounted on the flat plate 10 which is an example of the mounting plate, the flat surface of the flat plate 10 and the annular fluorescent lamp are substantially spaced from each other. I was in contact with nothing. However, for example, when the annular fluorescent lamp is mounted on a flat surface such as the flat plate 10, the mounting surface of the flat plate 10 and the annular fluorescent lamp are in contact with each other with a predetermined angle and a gap. The ring-shaped fluorescent lamp having a shape corresponding to the shape of the ring-shaped fluorescent lamp is a mounting plate that matches the shape of the ring-shaped fluorescent lamp mounted on the mounting plate.
