Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to a packaging container in which a band-like body is formed into a cylinder to store an object to be packaged.

(Prior Art) A cylindrical packaging container for storing a cylindrical, conical, etc. packaged object is sometimes used. This is generally formed into a cylindrical shape by joining both ends of a band-shaped body. For example, 1982 2

The one shown in No. ``Collection of Well-Known and Commonly Used Techniques'' (Packaging, Packaging Industry), page 112, and the one shown in Japanese Utility Model Application Publication No. 77875/1983 are known.

(Problem to be solved by the invention) However, the former has a pair of ears protruding from one end of the strip on both sides in the width direction, a pair of arc-shaped notches, and the other end has the above-mentioned tabs. A V-shaped cut and a chevron-shaped cut for inserting the arc-shaped piece formed by the above-mentioned arc-shaped cuts are provided corresponding to the pair of ear pieces. After aligning both ends of the strip, the pair of ears on one end are fitted into the V-shaped notch on the other end, and the arc-shaped piece on one end is fitted into the chevron-shaped notch on the other end. It is formed into a band-like shape. Therefore, in assembling it, there are two steps: shortening the distance between the pair of ears at one end, fitting these ears into the V-shaped notches at the other end, and expanding them back to their original positions. Two different types of work are required, one is to slide the arc-shaped piece into the chevron-shaped cut in the longitudinal direction of the band, and the other is to fit it together, making the production time-consuming.
It was inevitable that it would be expensive.

The latter type has staggered cuts that mesh with each other in the width direction near both end edges of the strip. Therefore, when assembling, both ends must be twisted apart from each other to a position where they engage with the notch, and then they engage with each other in the notch, and both ends of the strip must be moved by approximately the width of the strip. First, the range of movement becomes large, resulting in poor workability and troublesome manufacturing.

The present invention has been made in consideration of the above-mentioned circumstances, and an object of the present invention is to provide a packaging container that can be easily assembled and manufactured at low cost.

[Structure of the idea]

(Means for Solving the Problem) The packaging container of the present invention has a pair of plates in which a cut is made along the longitudinal direction from the edge on each of the plate surfaces at both ends of a strip shaped like an elongated rectangle, and the tip is cut in the width direction. By providing L-shaped cut portions spaced apart in the width direction, a hook portion consisting of a center piece and both side pieces is formed, and the pieces at both ends are alternately overlapped to extend along the width direction. It is characterized in that the tips of both cut portions are engaged with each other by being relatively shifted to form a cylindrical shape.

(Function) The packaging container of the present invention stores, for example, an object wrapped around it. At this time, after the object to be packaged is placed on the plate surface of the strip, the strip is wrapped around the object and bent to form a cylindrical space, in which the object to be packaged is stored. Next, by overlapping the pieces of both ends alternately and shifting them relative to each other along the width direction, the tips of both notches engage each other, completing the assembly, and storing the packaged item. do. Both ends of the strip can be assembled with a small movement corresponding to the length of the notch at the tip in the width direction, and workability can be improved.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a strip-shaped body, and this strip-shaped body 1 has an elongated rectangular shape and has fold lines 2, 3, 4, 5, 6, and 7, and hooks 10 and 11 are formed at both ends 8 and 9 in the longitudinal direction. . Each hook part 10, 11 is cut in the longitudinal direction from the edge on each plate surface, and has a tip 12d,
By providing a pair of L-shaped notches 12, 12 and 13, 13, which are formed by cutting 13d in the width direction, and spaced apart in the width direction, the central piece 12
a, both side pieces 12b, 12c and 13a, 13
b, 13c. These hook parts 10,
11 is each piece 12a, 12b, 12c and 13
By overlapping alternately a, 13b, 13c and relatively shifting them in the width direction of the strip 1, the tips 12d, 13b engage with each other, thereby forming a cylindrical shape and creating a space for storage. 14 is formed,
A packaged object 15, for example a truncated conical light bulb fixture 17 with a socket 16, is accommodated therein.

Note that 18, 18 and 19, 19 are triangular notches formed at the ends of each notch 12, 12 and 13, 13, and the engagement of each notch 12, 12 and 13, 13 is prevented. This is to make it easier. Also, 20, 20, 20, 20 are broken lines 2,
This is a notch formed between 4, 5, and 7, which fits into the corner of the object 15 during packaging to prevent the object from moving easily.

Next, the operation of this embodiment will be explained. The base portion 17 of the device 17 is inserted between the fold lines 4 and 5 of the strip 1.
After arranging part a, it is bent along the fold lines 2, 3, 4, 5, and 6 so as to wrap it around the instrument 17. Then, a cylindrical space 14 is formed, and an instrument 17 is formed in this space.
to store. Next, hook parts 1 on both ends 8 and 9
The cut portions 12 and 13 of Nos. 0 and 11 are aligned on the same line and abutted against each other. Then, the center piece 12a of the hook part 10 of the one end part 8 is inserted under the center piece part 13a of the hook part 11 of the other end part 9, and the both side pieces 12 of the one end part 8 are inserted.
b, 12c, both side pieces 13b, 1 of the other end 9
Both ends 8 and 9 are slid in the direction of overlapping along the longitudinal direction of the strip 1 so that the strip 3c is inserted. As a result, as shown in FIG.
a fits between both side pieces 13b and 13c of the hook part 10. Next, attach both the hook parts 10 and 11 to the belt-shaped body 1.
relative shift along the width direction. That is, by shifting the one end portion 8 in the direction of the arrow in FIG.
d and 13d are fitted and hooked together to complete the assembly, thereby storing the object to be packaged, that is, the instrument 17. At that time, the ends 8 and 9 of the strip 1 only have to be shifted by approximately the length of the tips 12d and 13d of the notches 12 and 13, and the range of movement is small.
Improves work efficiency.

The upper part of the instrument 17 and each corner of the base 17a fit into the notches 20, thereby allowing the instrument 17
movement is prevented.

Note that the notches 20 are not necessarily required, and there is no problem in practice even if they are not provided.

[Effect of idea]

According to the present invention, the strip is assembled by overlapping the center piece and both side pieces at both ends differently, and by shifting them relative to each other along the width direction, the tips of the cut portions engage with each other. Therefore, both ends of the band-shaped body need only be shifted by approximately the length of the tip of the notch cut in the width direction, and the range of movement is small, which improves work efficiency.
