Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a case for an annular fluorescent lamp.

For example, as shown in FIG. 1, a conventional case of this type is constructed by integrally forming a lid B for closing the opening on the edge of the side wall on the opening side of the case body A, which is a rectangular cylinder with a bottom. Therefore, when the case main body AK annular fluorescent lamp L is housed, its outer peripheral surface is completely covered by the case member.

Therefore, it has the excellent effect of sufficiently reducing damage to the annular fluorescent lamp L due to external impact, etc. However, on the other hand, it has the disadvantage that the price is high due to the large amount of case members, such as cardboard, used. be.

In view of these points, the present invention provides a case for an annular fluorescent lamp that can effectively reduce the cost by reducing the amount of case members used without impairing the individual packaging properties of the annular fluorescent lamp. , Examples will be described below.

Referring to FIGS. 2 to 5, reference numeral 1 denotes a substantially rectangular case member made of corrugated paper, for example, and has tongues 2 and 3 integrally formed at both ends.

The width of the tongues 2 and 3 is set to be approximately equal to the inner diameter of the annular fluorescent lamp L.

A cut-and-raised piece 4 is formed in the center of the tongue piece 2 in a shape that slightly protrudes from the part to be bent toward both sides, and in the center part of the tongue piece 3, a cut-and-raised piece 4 is formed slightly toward the end side than the part to be bent. A substantially U-shaped cut 5 is formed therein.

A hole 6 is formed by bending the notch 5, and the cut and raised piece 4 is inserted and locked.

The maximum medium t1 of this cut and raised piece 4 and the width t2 of the hole 6 are Lt>1
The relationship is set to 2.

Similarly, an outwardly curved portion is formed in the central portion of the notch 5, but this is for facilitating insertion of the cut and raised piece 4.

7 is the side wall 8, 9, 10, 11.1 in the case member 1
The case body is a rectangular cylindrical case body formed by bending the boundary portions of the case member 1, and both ends of the case member 1 are abutted at a portion facing the center portion of a side wall 10 having a large area.

The tongue pieces 2 and 3 are bent inward of the case body 7 at a substantially right angle.

The portion surrounded by the notch 5 formed in the tongue piece 3 by this bending is not bent, and the side wall 12
located almost on the same plane.

For this reason, when inserting the cut and raised piece 4 into the hole 6 formed by the notch 5, the curved portion acts as a guide, making it possible to smoothly insert and lock the cut and raised piece 4 into the hole 6. can.

Next, a method for individually packaging the annular fluorescent lamp L will be explained.

First, as shown in FIG. 5, a side wall 1 is attached to the case member 1.
An annular fluorescent lamp L is placed on the 0.

Then, the boundary portion between the side wall 10 and the side walls 9 and 11 is
, 11 are bent at right angles so that they face upward, and the boundary portions between the side walls 9, 11 and 8, 12 are
Bend it about 120 degrees so that it is positioned above the annular fluorescent lamp L.

In this state, the tongue pieces 2 and 3 are bent inward so as to be approximately perpendicular to the side walls 8 and 12.

As a result of this bending, a hole 6 is formed in the notch 5 portion since the portion surrounded by the notch 5 is not bent.

When the side walls 8, 12 are further bent from the boundary with the side walls 9, 11, the lower ends of the tongues 2, 3 abut and abut, and are fitted and locked to the inner diameter portion of the annular fluorescent lamp L. .

Thereafter, individual packaging is completed by inserting and locking the cut and raised pieces 4 into the holes 6 using the curved portions as guides.

Similarly, the insertion of the cut and raised piece 4 into the hole 6 can also be carried out at the stage of bringing the side walls 8, 12 closer to the annular fluorescent lamp L.

Since both sides of the case body 7 are open in this manner, the amount of use of the case member 1 can be greatly reduced, and the cost can also be reduced.

In particular, since openings are formed on both sides of the case body 7, the annular fluorescent lamp L can be seen from the outside, making it necessary to handle the case carefully, which not only reduces the risk of breakage, but also reduces the risk of damage to the case. The lighting check performed at the time of sale can be carried out while the product is stored in the case, which can also be expected to save time and effort.

Further, the annular fluorescent lamp L has a tongue piece 2 which is approximately equal to the inner diameter of the annular fluorescent lamp L;
3, and the tongue pieces 2 and 3 are securely overlapped by inserting and locking the cut and raised piece 4 into the hole 6, so that no misalignment may occur during transportation or handling. In addition, since shocks are not directly applied to the product, the number of breakage accidents can be significantly reduced.

In particular, if curved recesses that can fit into the bulb are formed on both sides of the tongues 2 and 3, even greater effects can be obtained.

Further, since the cut and raised pieces 4 formed on the tongue pieces 2 and 3 are inserted into the holes 6, it is possible to reliably prevent the case body 7 from being torn apart when being handled.

Furthermore, since the part surrounded by the notch 5 is not bent by bending the tongue piece 3 and is located on the same plane as the side wall 12, the curved part guides when the cut and raised piece 4 is inserted into the hole 6. Since it also acts as a guide, the insertion can be performed reliably and the insertion workability can also be improved.

As described above, according to the present invention, the amount of case members used can be reduced without impairing the individual packaging of the annular fluorescent lamp, and at the same time, the cost can be effectively reduced.
