Description

  The present invention relates to a structure that can be used as a package for packaging an article having a long overall length.

  When packaging an article having a long overall length, a package formed by dividing the article into two or more cylindrical members is used. For example, the package of Patent Document 1 includes first and second cylindrical members having a polygonal shape. The first tubular member is provided with a slit on a predetermined outer wall surface of the connecting end portion. The second cylindrical member is formed in a cylindrical shape larger than the first cylindrical member so as to cover the outside of the first cylindrical member. A locking piece for inserting and locking the slit from the first cylindrical member from the outside to the inside is provided at the connecting end portion of the second cylindrical member.

  However, since the packaging body described in Patent Document 1 has a shape in the direction orthogonal to the axis of the second cylindrical member larger than that of the first cylindrical member, when packaging a cylindrical article, Thus, a gap is generated between the article and the article. Therefore, the buffering performance is low, and it is not suitable for packaging of articles that need to reliably avoid impacts such as LED fluorescent lamps. Moreover, since it is necessary to manufacture another blank with a different 1st cylindrical member and a 2nd cylindrical member, the cost regarding production cost and physical distribution (conveyance and management) becomes high.

  The blank of the cylindrical member 10 is delivered to the manufacturer of the article 1 in the blank state shown in FIG. And it is used as a package which assembles at a manufacturer and wraps the article 1. The article 1 of the present embodiment is an LED fluorescent lamp with a total length exceeding 2 m, and the tubular member 10 is formed with a total length exceeding 1 m.

  When assembling the cylindrical member 10, for example, after the outer wall surface 11a is bent with respect to the inner wall surface 13, the outer wall surface 11b is bent with respect to the outer wall surface 11a. Next, after bending the outer wall surface 11c with respect to the outer wall surface 11b, the outer wall surface 11d is bent with respect to the outer wall surface 11c. Thereby, the outer wall surface 11 d is superimposed on the outer side of the inner wall surface 13. Further, the locking piece 16 is bent with respect to the outer wall surface 11d and inserted and locked in the corresponding locking groove 14. Thereby, as shown in FIG. 1, the cylindrical member 10 in which the shape in the direction orthogonal to the axis forms a square cylindrical shape is formed.

  When the pair of cylindrical members 10A and 10B are assembled as described above, the first cylindrical member 10A is placed on the left half of the article 1 from the connection end 21A side. Further, the second cylindrical member 10B is placed on the right half of the article 1 from the connection end 21B side. Thereafter, the connecting end portions 21A and 21B of the cylindrical members 10A and 10B are engaged with each other and connected, and the stopper portions 19a and 19b are folded inward to wrap the article 1. Note that various changes can be made to the procedure for packaging the article 1.

  Next, the connection of the connection end portions 21A and 21B of the first and second cylindrical members 10A and 10B will be specifically described.

  First, as shown in FIGS. 2A and 2B, the outer wall surfaces 11a to 11d of the first and second tubular members 10A and 10B are arranged so as to be positioned on the same plane. Then, the first and second cylindrical members 10A and 10B are relatively moved along the axis line so as to approach each other.

  Next, as shown in FIG. 3A, the first slits 22A and 22B of the first and second cylindrical members 10A and 10B are engaged with each other. At this time, the outer overlapping portion 27A of the first cylindrical member 10A is positioned outside the inner overlapping portion 28B of the second cylindrical member 10B, and the outer overlapping portion 27B of the second cylindrical member 10B is moved to the first cylindrical member 10B. It is located outside the inner overlapping portion 28A of the cylindrical member 10A.

  As shown in FIG. 3B, when the inner and outer overlapping portions 29A and 29B of the first and second cylindrical members 10A and 10B are in a position where they face each other, one of the inner and outer overlapping portions 29A and 29B faces downward. The first and second cylindrical members 10A and 10B are moved along the axis while being pressed.

  Thereby, as shown to FIG. 4 (A), 1st slit 22A, 22B meshes | engages deeply. Further, as shown in FIG. 4B, one of the inner and outer overlapping portions 29A and 29B overlaps the other outer side. The second slits 25A and 25B of the cylindrical members 10A and 10B having the inner overlapping portions 28A and 28B disposed on the inner side of the cylindrical members 10A and 10B having the inner overlapping portions 28A and 28B disposed on the outer side are provided. Engage with (insert through) the wall. FIG. 4B shows a state in which the inner and outer overlapping portions 29A of the first cylindrical member 10A are arranged outside the inner and outer overlapping portions 29B of the second cylindrical member 10B. Therefore, the second slit 25B of the second cylindrical member 10B is engaged with the ridges of the outer wall surfaces 11c and 11d of the first cylindrical member 10A.

  As shown in FIG. 5A, when the first and second cylindrical members 10A and 10B are further moved, the lock grooves 24 and 24 of the first slits 22A and 22B are engaged with each other, and the cylindrical members 10A and 10B are engaged. Are located on substantially the same straight line. Further, as shown in FIG. 5B, the inner / outer overlapping portion 29B of the cylindrical member 10B disposed on the inner side contacts the inner wall surface 13 of the cylindrical member 10A. In this state, the relative movement of the cylindrical members 10A and 10B is stopped.

  In this state, the lock grooves 24 and 24 of the first slits 22A and 22B are engaged in a direction orthogonal to the axis. Therefore, even if an external force is applied to the cylindrical members 10A and 10B along the axis in the separation direction, movement in the separation direction can be prevented. In addition, in the present embodiment, the engagement of the insertion locking portions 31 formed on the outer overlapping portions 27A and 27B of the cylindrical members 10A and 10B is inwardly pressed, thereby engaging the cylindrical members 10B and 10A positioned on the inner side.
