Field of the Invention The present invention is suitable for distributing spirally wound connecting nails used in a magazine of an automatic nailing machine in a relatively small number of units or carrying them on site. The present invention relates to a packaging container for connecting nails.

[0002]

2. Description of the Related Art In an automatic nailing machine, a large number of nails are connected in parallel with long shafts, for example, two wires or plastic sheets, with their shafts in parallel. These connecting nails are spirally wound and used by being loaded into a magazine of an automatic nailing machine. Usually, several tens of the above-mentioned connecting nails are transported and stored in a cardboard box or the like, but during the distribution process, the spiral state collapses in the cardboard box and the magazine is filled in the magazine of the automatic nailing machine May not be possible. Packaging trays proposed by the applicant have already been known as measures to prevent the winding of the connecting nails in the cardboard box during the distribution process. The structure of the packaging tray is such that a spacer formed with a large number of concave portions for accommodating the distal end portion of the spirally wound connection nail is interposed between each step of the connection nail stacked in the cardboard box. In this way, it is possible to prevent the connecting nail from being collapsed during transportation or storage.

[0003]

By the way, the cardboard box contains several to ten connecting nails stacked in several stages of several to ten pieces per one stage. Transportation is heavy and handling is difficult.
Therefore, unpacking the cardboard box and distributing it in units of a small number of connecting nails, or taking out the amount of connecting nails used from the cardboard box and carrying them to the site. However, the connecting nails taken out of the cardboard box are liable to be rolled out of the box, which makes it difficult to load the nails into the magazine, and that the nailing operation by the nailing machine is normally performed. Problems such as inoperability occurred. In addition, it is difficult to transport the connecting nails in the packaging tray taken out of the cardboard box, and it is necessary to prepare a dedicated transport / storage case. In addition, when transferring to these cases, inconveniences such as collapse of the swirl form have occurred.

Accordingly, the present invention has been proposed in view of such circumstances, and even when a large number of connecting nails are stacked and accommodated in a cardboard box, and are transported and stored, the curling of the spiral state is prevented. It does not occur, and even when storing and transporting connecting nails used in the field in small units,
A container for connecting nails that does not require the preparation of another container, does not cause unraveling during storage or transportation, and does not cause problems such as poor nail feeding with an automatic nailing machine. It is an object to provide

The upper case 7 has a plurality of connecting nail storage portions 10 for storing and holding substantially half of the head side of the spirally wound connecting nails 8 in a thin rectangular plastic flat plate 9. It is arranged in a zigzag pattern on one side. As shown in FIGS. 5 and 6, each of the storage portions 10 is constituted by a peripheral wall portion 12 connected to the flat plate 9 at a lower edge portion 11 and an upper bottom portion 13 formed above the peripheral wall portion. It is formed in a cylindrical shape with a bottom, and its lower part is opened so that the head side of the connecting nail can be stored. The inner diameter of the peripheral wall portion 12 is formed to be substantially the same as the diameter of the connection nail wound spirally. The upper bottom portion 13 is formed in a conical shape in which a central portion is lifted upward, and a columnar body 14 is formed at the center portion of the upper bottom portion 13 and hangs down toward the inside of the storage portion.

The lower case 4 is formed of a rectangular plastic thin plate having the same shape as the upper case 7 and has a plurality of spirally wound connecting nails 8 for accommodating and holding substantially half of the nail tips on the nail tip side. Are formed in a staggered arrangement on one side of the flat plate. Each of the storage portions 15 is formed in a cylindrical shape constituted by a peripheral wall portion 17 in which the flat plate 9 and the upper edge portion 16 are continuous and a lower bottom portion 18 formed below the peripheral wall portion. The connecting nail 8 shown in FIG. 1 is opened so that it can be freely moved in and out. The inner diameter of the peripheral wall portion 17 is formed to be substantially the same as the diameter of the connecting nail 8. The bottom portion 18 is formed in a conical shape whose central portion is lifted upward, and a cylindrical body 19 bulging upward is formed at the central portion.

In the above embodiment, the central portion corresponds to the spirally wound connecting nail which is lifted upward, and the upper bottom portion 13 of the upper case has a spirally wound connecting nail. The nail 8 is formed in a shape conforming to the shape formed by the nail head 20. The shape of the lower bottom portion 18 of the lower case is formed by the tip 21 of the nail in a state where the nail is spirally wound. The shape is adapted to the shape.
