Description

TECHNICAL FIELD The present invention relates to a packaging container for bulbs.

2. Description of the Related Art Conventionally, as a packaging container for a bulb, for example, a U-shaped fluorescent lamp, as shown in FIG. 7, a folding piece 18, a bulb protecting piece 19 and a tongue piece are provided at the open end of a rectangular tubular packaging container body 17. 20 in series, the folded piece 18 is folded back inside the packaging container body 17, and the tube protection piece 19 is bent from this folded piece so as to close the opening of the packaging container body, and then the tube protection piece 19 tongue piece Bend 20 to the open end side, and
Supports 23, 24 along the notches 21, 22 provided at the corners of the
It has been proposed and used to push the inside of the main body of the packaging container and to support the tube protecting piece 19 and the like from the outside by these supporting portions (Japanese Utility Model Publication No. 61-28786).

The problem to be solved by the invention is such a packaging container in which a protective object separate from the rectangular tubular packaging container book is inserted inside over substantially the entire length thereof, and the protective tube protects the tube. Compared with, the lid, which is a protector, is integrated with the body of the packaging container, improving workability and reducing the total amount of materials used.
As shown in FIG. 8, not only wasted material is generated in the shaded area, but also the folding piece, the tube protecting piece, and the tongue piece must be bent three times to close the opening of the packaging container body. Therefore, it cannot be said that the workability of assembling is also good.

The present invention is to provide a packaging container for a tube in which the materials used are reduced as much as possible without impairing the protection of the tube housed therein and the workability of assembly is good.

Means for Solving the Problems The packaging container for a tube according to the present invention includes first and second opposing containers.
Of the rectangular cylindrical packaging container main body having two main surfaces opposite to each other and a tube protection piece continuously provided at the open end of the first main surface, and the second main surface and the second main surface. A cut parallel to the opening end is provided at each corner formed by both side surfaces connected to the main surface, and the tube protection piece is bent so as to close the opening of the packaging container body, and the cut is made from the cut. The corner portions are respectively folded inside the packaging container main body to form a folding portion, and the tube protection piece is supported from the outside by the folding portion.

With this configuration, since the tube protection piece is continuously provided at the opening end of the packaging container body, the opening of the packaging container body can be easily closed by bending the tube protection piece only once,
Further, the tube protection piece can be easily supported from the outside by the folded portion. Further, even if vibration or impact is applied, the tube protection piece is firmly supported by the folded portion, so that the tube housed inside is sufficiently protected without the risk of popping out and being damaged. .

Example As shown in FIG. 4, the tube packaging container of the example of the present invention is made of one corrugated cardboard, and is assembled with the first and second main surfaces 1 and 2 facing each other in the assembled state. The packaging container body is composed of the side surfaces 3 and 5 and the side surface 4 which face each other. The side surface 5 also serves as a margin, and the side surface 3 is bonded to the side surface 5 with an adhesive to form a rectangular tubular packaging container body 6 as shown in FIG. Side 3
The corners on both ends of the
3,15 can be folded. At the open end of the first main surface 1 of the packaging container body 6, a tube protection piece 7 is continuously provided, and is formed by the second main surface 2 and both side surfaces 4 and 5 continuously provided at the second main surface 2. Notches 8 and 9 parallel to the open end of the packaging container body 6 are provided at the corners. Then, the tube protection piece 7 is bent so as to close the opening of the packaging container body 6 (see FIG. 3), and the corners are respectively folded into the inside of the packaging container body 6 from these cuts ( (See FIG. 1). Further, the corners on the other open end side of the packaging container body 6 are respectively provided with cuts 10 and 11 in a diagonal direction, so that the corners can be folded inside the packaging container body 6 from these cuts, respectively. Has become.

Using the tube packaging container having such a configuration,
As shown in the figure, for example, the glass bulb 12a and the base 1
To package the U-shaped fluorescent lamp 12 consisting of 2b,
The U-shaped fluorescent lamp 12 is housed in the packaging container body 6 shown in the figure, and the bulb protection piece 7 connected to the opening end is bent 90 ° to close the opening (Fig. 3), and then cut. The tube protection piece 7 is supported from the outside by folding portions 13 and 14 formed by folding the corner portions of the packaging container main body 6 from its inside into the inside thereof, respectively (FIG. 1). Further, the base portion 12b of the U-shaped fluorescent lamp 12 is supported by the folded portions 15 and 16 formed by folding the corners of the packaging container body 6 from the cuts 10 and 11 inside thereof.

5A, 5B, and 5C show a plan view, a front view, and a side view, respectively, of a U-shaped fluorescent lamp housed in a tube packaging container.

According to the above configuration, the tube protection piece 7 is continuously provided at the open end of the packaging container body 6 and is supported by the folding portions 13 and 14 from the outside thereof, so that the vibration is generated during handling or transportation. ， Even when a shock is applied, the tube protection piece 7 is firmly supported by the folded portions 13 and 14. Therefore, the U-shaped fluorescent lamp 12 therein is sufficiently protected from impact and the like. In addition, since the tube protection piece 7 is connected to the open end of the packaging container body 6, the material required for making the packaging container can be reduced and the cost can be reduced as compared with the conventional example. Since the opening of one end of the packaging container main body 6 can be closed by bending the ball protection piece 7 once, the assembly thereof becomes extremely simple and the workability can be remarkably improved as compared with the conventional example.

Effects of the Invention As described above, the present invention can reduce the material used and the cost and can greatly improve the workability of the assembly as compared with the conventional one, without impairing the protective property of the bulb. It is possible to provide a tube packaging container having an excellent effect.
