The present invention relates to a packaging member of a fragile goods, the packaging member is particularly applied to the packaging of eggs can be applied to other fragile goods.

There are many packaging materials and packaging methods for fragile products, especially eggs, but most of them have disadvantages such as the complexity of manufacturing methods, the high cost of materials, their volume, or the lack of protection against fragile products. .

The present invention, in order to compensate for the above-mentioned drawbacks, the packaging member has several parallel bearings extending in the longitudinal direction of the packaging member, each of which has one corrugated band and one cloth-like covering band fixed thereto. The cover band is positioned outside of the upright package, and the supporting paddles are connected to each other on the fold line only above the neck of the pleat, and the supporting paddles are folded along the above-mentioned folding line to wrap the object to be packed. It is characterized by being able to be positioned correctly.

This packaging member has the advantage of being able to be manufactured in a relatively simple mass in a minimal material.

The member is flexible to support the packaged goods so that it is not damaged.

In addition, it can be visually observed from the outside and free of air inflow, which is particularly effective for packaging eggs.

Moreover, when not in use, it is easy to fold and accumulate the accumulated packing.

Also, a covering band, such as a piece of cloth, is made into a covering band and a gathering band, which is connected to a crimped band and then alternately spaced into several parallel longitudinal holes, whereby these holes completely separate the covering band. Several restraints connected parallel to each other, defining the upper part of the upper part of the pleats, are inserted into the pleats of the corrugation after the goods are packaged so that the back rests are parallel to each other and to the fold lines parallel to each other. It is characterized in that it is bent along and positioned around the object to be wrapped.

Such a packing member can manufacture the material wound on the winding side with a simple machine.

You can also pack fragile goods on the spot.

It can be finished from one place to the packaging, or can be made only by packing members and sent to the packaging factory.

The present invention will be described in detail with reference to the drawings.

Referring to Figures 1-3, the packaging member 1 is for egg packaging, but this member is also capable of packaging fragile or pressure sensitive objects such as fruits, glassware, etc. And a corrugated band 2 and a flat cover band 3.

The two bands (2) and (3) consist of chipboard of about 1.5 mm thickness and these bands can be suitably coated with resin, beeswax or other materials, if necessary.

The corrugated band 2 is fixedly connected to the cover band 3 by an adhesive in a flat area at constant intervals. The angle α between the inclined surfaces 19 of the corrugations opposite each other is 80-110 degrees and is close to about 90 degrees.

The upper part 5 of the pleats is flat.

The length (t) of each corrugation is consistent with the set pitch of the object to be packed. For eggs, 4-5 cm and 4.5 cm are suitable. The length t of the wrinkles is suitably 2-3 times about 2.5 times larger than the height h of the wrinkles.

The cuts 6 are formed in both the corrugated band 2 and the cover band 3, which cuts parallel to each other with respect to the longitudinal direction B of the filling material and define the upper part 5 of the corrugation.

As shown in FIG. 2, there are a total of four cuts 6 which are substantially divided into five side-by-side pedestals 7, 8, 9, 10 and 11, each of which is connected to each other only at the top of the corrugation. Has matching wrinkles. The intermediate base bearing 9 is twice the width of the two partial base pads 7 and 11.

The width of the intermediate pedestal 9 is approximately twice the height h of its wrinkles. In the planar state of the packaging member, the objects to be packaged are, for example, six eggs arranged side by side, which are pushed into each of the corrugations 15 in the direction of the arrow D in FIG. Raised to. Then the support pads (7) and (8) on one side and the support pads (10) and (11) on the other side are bent upright by about 90 ° to the fold line (32) on the top of the corrugation (5), and the fourth As in and 6 degrees, it is U-shaped.

Therefore, the eggs 18 are surrounded on three sides by the pedestal (8, 9, 10). The two outermost pedestals 7 and 11 are then packaged as shown in FIG. 7 with 90 " fold inward at fold line 33, respectively.

This structure is completed by an adhesive strip 12 attached to adjacent pedestals 7 and 11 in an upright state in which eggs are embedded.

The eggs 18 are now four sides surrounded by the pedestals (7) and (11), but due to the nature of the packaging, the surrounding air can come into contact with the eggs, which is very important in keeping the eggs fresh for a long time.

It is also easy to see if the egg is broken from the outside.

As already recognized, the upright pavement is generally rectangular in shape. The goods are cushioned against impacts as they have a slight resilience of the inclined portion 19 of the pleats 15 and the packaged goods are generally supported by the inclined portion 19 rather than the flat valley bottom 4.

Moreover, since the elasticity of the inclined portion can flexibly embrace objects of various sizes, the deformation of the inclined portion 19 varies according to the size of the related product.

Moreover, the accumulated packaging can absorb a significant amount of pressure when stacked. 8 shows that the folds can be easily folded when loading or transporting the packaging member.

In order to easily fold the pleats, the tops 5 of these pleats are made of fine lines 36 and 37 with fine holes formed laterally in the pavement.

Since the fine lines 36 and 37 can easily fold and unfold the wrinkles, the thickness of the corrugated bands 2, which is three times as large as the corrugated bands 2 of cardboard, and the thickness of the cover bands 3 remain.

The upright installation of the folded folds is achieved by simultaneously inserting the operator's fingers into the empty space 39.

In order for the fold to be fully folded, the following relationship, i.e., subtracting the width r of the upper portion 5 from the length S of the inclined portion 19 of the fold, It must match the distance K. (K = 2S-r)

9 shows the double enumerated pavement, which is bent in an intermediate band along fold line 17.

The rest of the structure is almost identical in principle to 1-8, but in Fig. 9 the eggs are erected in contrast to 1-8.

For reference, the manufacturing method is as follows.

The manufacture of such a packaging member as described above and a method of standing it up into the resulting packaging is shown in FIGS. 10 and 11. Referring to FIGS. 10 and 11, the member for the corrugated band 2 is released from the crimp 20 and passes between the two forming wheels 21, 22, wherein the forming wheels 21, 22 are fitted. The bite has a tooth-shaped blade that creases the bands that lead into it.

The member for the cover band 3 is provided from the crimp 23 under the crimp 20, which is sent by the guide tollors 24, 25.

Before the two bands are joined to each other, the corrugated band 2 is brought into contact with the adhesive roller 27 partially embedded in the adhesive container 26, whereby the adhesive is applied to the bottom of the corrugated bone.

A plurality of pressure rollers 28 are installed on the corrugated band to ensure contact between the band and the adhesive roller 27.

The thin plate thus formed is guided by four round knives 30, where the pleated bands and the cover bands are cut off to distinguish five parallel support bands 97, 8, 9, 10 and 11. The round knives are sized and positioned in relation to the wrinkles so that the upper portion of the wrinkles 5 is not cut. Eggs 18 or other articles to be packaged are pushed from the sides into the valleys of the corrugations 15 in the direction of the arrows simultaneously or continuously.

For this purpose, install a pushing device 31 for eggs.

The support landings 8 and 10 are folded at 90 ° from the fold line 32 from the intermediate support landings 9 plane to have a shape as shown in FIG.

For this purpose, a fixed guide pedestal 40 is installed to upright the support band sideways.

Then, at the fold line 33, the support skins 7 and 11 are bent at 90 ° from the plane of the bands 8 and 10, respectively, to form the final shape as shown in FIG.

The adhesive strip 12 is attached on the adjacent line of the two pieces of cloth 13 in the longitudinal direction and the package is cut to the required length.

The whole manufacturing process can be carried out step by step or continuously. On the materials of the cigarettes 20, 23, printing can be carried out in advance or between work processes.

The manufacture of the double row packaging material of FIG. 9 is carried out in a similar manner, but the difference is that the width of the material is wider than that of the packaging of FIGS. There is one more fold line 17.

At the bottom, an adhesive strip 38 is attached to place this package in the same position as shown in FIG.

The two stripped portions 16 can be glued together as needed.
