Description

[Detailed description of the invention] (Industrial application field) This invention relates to packaging for light and medium weight products such as wireless products and electrical appliances.The development of a molding technique reduces the amount of packaging material and simplifies the packaging work. It is a package that allows for

(Constitution of Conventional Example and its Problems) Conventionally, light and medium weight products are packaged using a cushioning body attached to the product, an A-1 type cardboard box, or the like.

However, in recent years, so-called sleeve packaging, in which flaps and the like are removed, has been considered in order to reduce the amount of packaging material and packaging work time.

In such conventional packaging methods, other auxiliary materials such as PP bands, tape, and Stella pull are required to tightly secure the cushioning body and the sleeve-shaped cardboard that wraps it, which increases packaging material costs, packaging work, and management. It had the disadvantage of being inefficient in terms of.

(Purpose of the invention) The present invention eliminates the drawbacks of conventional sleeve packaging, eliminates the need for auxiliary materials for tightly fixing the cushioning body and the sleeve-shaped cardboard box packaging, secures the fit and fixation, The aim is to reduce packaging materials and improve packaging efficiency.

(Structure of the invention) The packaging body of the invention is formed into a rectangular tube shape, and a corrugated center core is exposed on at least two corresponding inner surfaces so as to have uneven stripes in a direction perpendicular to the axis of the tube. and a buffer body having an outer shape that fits inside the packaging cylinder and having uneven stripes on at least two outer sides that fit into the uneven stripes of the corrugated center core. be.

(Description of Examples) FIG. 1 shows a developed view of a packaging cylinder, and FIG. 2 shows a buffer body.

The packaging cylinder is made of a corrugated board, and when unfolded, is formed into a long shape with a joint 1 and side plates 2, 3, and 4°5 connected together.

The corrugated board is bent along the valley fold lines 8a, 8b, 8c, and 8d to form a rectangular packaging tube as shown in FIG. 3.

Further, when the corrugated board is formed into a packaging tube, two corresponding surfaces on the inside, ie, side plates 2 and 4 shown in the drawings, are provided.
The corrugated cores 6a, 6b are exposed on the surfaces of the packaging tube, and back liners 7a, 7b, 7c are pasted on the surfaces of the other side panels 3.5 to provide strength to the packaging tube.

The uneven lines of the corrugated center cores 6a, 6b are oriented in a direction that intersects the axis of the cylinder.

The shock absorbers 9 and 10 shown in FIG. 2 have a shape that can fit inside the packaging cylinder, that is, the outer shape is square, and the outer two sides are provided with a center core 6a of the packaging cylinder as shown in FIG. ,
It has a concave line 12a and a convex line 12b into which the concavo-convex line 6b fits.

The two buffer bodies 9 and 10 are connected to the product 1 as shown in FIG.
1 is held and wrapped in a packaging cylinder, and the packaging cylinder is joined at the joint.

At this time, the grooves 12a and 12b of the shock absorbers 9 and 10 fit into the grooves of the cores 6a and 6b exposed on the inner surface of the packaging tube, and the axial movement of the packaging tube is prevented. ,
Securely fixed in the packaging cylinder.

Further, the fixing does not require any other auxiliary materials such as PP bands, tapes, and Stella pulls.

Of course, the packaging tube has both ends open and can be easily formed by bending a long plate, which saves materials and facilitates the packaging operation.

(Effects of the invention) This packaging device according to the invention simplifies the fitting and fixing of the shock absorber attached to the product, reduces the amount of packaging material, and allows mechanization to be introduced, thereby improving the efficiency of packaging work. By using the insertion method as the sealing method, repackaging is simplified.

Further, there is no need for auxiliary materials for tightly fixing the cushioning body and the cardboard, leading to a reduction in material costs.
