Description

[Detailed description of the invention] The present invention relates to a packaging container for a cylindrical member such as a cylindrical shock absorber, and a conventional container of this type has four side walls a, l), c, and d as shown in FIG. Lid pieces a' and c' are continuous to the ends of a pair of opposing side walls a and c of a rectangular cylindrical box body through folds e and f, and these lid pieces a',
Provide tongues a'' and c'' at the tip of c', bend one lid piece a' to close the end inside the box, then bend the other lid piece C' and stack it on top of it, A structure is used in which the tongue c'' is inserted into a notch h formed in the fold e.

When a cylindrical shock absorber is housed in a box constructed in this manner, the shock absorber is relatively heavy, so even if the shock absorber is transported horizontally, there is a risk that the lid may open due to vibration.

The purpose of this invention is to improve upon these conventional problems.It simplifies the structure, makes packaging easier, and improves work efficiency.It also limits the axial movement of the stored shock absorbers, etc. This is to prevent the shock absorber, etc. from being exposed from the container.

To explain the embodiments shown in the drawings below, in Fig. 1, 1 is a circular cylinder made by wrapping a material such as corrugated paper or paperboard. A set of parallel cuts 2 at appropriate locations from the end,
2' and 3,3' respectively, and these notches 2
, 2' and the notches 3, 3' form tongues 4.5 that are partially cut off from the periphery of the cylinder 1, and when the tongues 4, 5 are pushed in and deformed, these tongues It protrudes toward the mounting fittings 9 and 10 of the stored shock absorber 8 (see FIG. 2) and engages with the stepped shoulder to restrict its axial movement.

Figure 2 shows the case where both of the above mounting brackets are eyes (mounting lugs), and Figure 3 shows the case where the cylinder 1 is circular.
4, 5 and 6 show the case where the mounting fittings are studs and bolts, and FIG. 5 is a sectional view taken along line B-B in FIG. FIG. 6 is a sectional view of an embodiment in which three sets of notches are formed on the same circumference to provide three tongue pieces.

The above-mentioned tongue piece is for preventing the stored shock absorber etc. from being pulled out in the axial direction from the open end of the cylinder 1.
Several pieces can be provided on the same circumference as necessary at positions separated by a predetermined interval in the axial direction, and serve as a large hook for objects to be stored inscribed in the cylindrical body 1.

In addition to cylindrical shock absorbers, the present invention can be widely used for packaging cylindrical products such as small cylindrical hydraulic cylinders and dry batteries.

When storing an item in this packaging container, in the preparation stage, one of the tongues is pushed in near the left and right open ends to deform it, and after the item is placed in the container, the other tongue is pushed in and deformed. All you have to do is deform the pieces, and the axial movement of the stored items is restricted by the tongue pieces, so even if they are subjected to vibrations during transportation or are transported in large numbers vertically, they will not move out of the container like in the past. Not only do you not have to worry about the items falling out, but since no part of the stored items is exposed to the outside, there is no chance of them coming into direct contact with other items and causing damage. Since it is only necessary to use an unnecessary cylindrical body and make a part of it into a tongue piece, the structure is simple and packaging is easy, improving work efficiency, and when stacking a large number of cylindrical bodies, there is no wasted space. It has excellent practical effects as a container that can be stacked, is lightweight and durable.

Claims (1)

[Scope of utility model registration request] A set of parallel notches 2, 2, 3, 3, or several sets of notches are provided at a predetermined interval in the axial direction of the cylindrical body 1 that matches the outer diameter and overall length of a cylindrical member such as a shock absorber. tongue pieces 4, which are partially cut off from the periphery of the cylinder body 1;
5 is pushed inward to deform it, thereby bringing the tongue piece into contact with the end face of the cylindrical stored object such as a shock absorber, restricting its axial movement, and exposing the cylindrical stored object from the cylindrical body 1. A packaging container for cylindrical members such as cylindrical shock absorbers that can be accommodated without any problems.
