Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a collective packaging box, for example, a box for storing, transporting and storing a plurality of egg containers and other packaging bodies.

[0002]

[Background of the invention]

 A conventional egg container is an integrally molded product made of transparent plastic or recycled paper, etc., which is divided into two parts with substantially the same shape, and prevents damage to the egg during storage, transportation and display. Such an egg container is generally one in which the lower container body and the upper container body can be opened and closed about one edge and is biased to the open side. The open side free end is closed by being stopped by a stepper or the like so as to be in a housed state.

However, in the egg container having such a configuration, since the shape of the egg container as a whole when it is stored is uneven, the upper and lower stacking conditions are poor, and the efficiency of storage, transportation, and display is poor. In order to display the name of the egg producer, the place of production, the price, etc., it is difficult to print or put paper on the outer surface of the container because the entire container is concave and convex. Although the paper with these signs was put in, it has the drawback that the paper is greatly distorted due to the unevenness of the egg container, making it difficult to read.

Therefore, the present applicant previously proposed an egg container having a new shape in order to solve the above problems. That is, in this egg container, a predetermined number of storage portions having a depth equal to or higher than the height of an egg are formed at a predetermined position of a flat film by deep drawing. Then, in a state where the eggs are stored and arranged in the storage portion, the opening surface of the flat film is adhered with a sheet so as to cover the opening of the storage portion. That is, by making one surface of the egg container flat, it is possible to facilitate the stacking, and by sticking a predetermined printed matter on the flat surface, the visibility of the printed contents is improved.

By the way, in the above-mentioned novel egg container, since one surface is configured to be flat, it is possible to stack a large number of pieces in the upper and lower directions in a stable state. A certain number of egg containers are placed in a cardboard box having a volume in the vertical and horizontal directions (horizontal direction), and the egg containers are also stacked and stored above. After storage, the upper part of the corrugated cardboard box is closed to produce a collective packaging box, which is stored or transported in each corrugated box.

However, the collective packaging box body using the above corrugated cardboard box has the following various problems. In other words, since a cardboard box usually has a bottom and also has a lid, when storing it in the box, insert and place one egg container in the assembled cardboard box (only the lid is open). After storing a predetermined number, the lid is closed with a sealing member such as an adhesive or a tape (the bottom is also previously closed with the sealing member). In order to carry the egg container in that state and display the egg container in the store, the lid of the cardboard box is opened by removing the sealing material at the display location, and the egg container is stored in the upper position in the box. Each one must be taken out one by one and transferred to a display shelf or the like, which complicates the work.

Then, when all the egg containers have been transferred, the cardboard boxes are crushed. That is, the sealing member on the bottom side is also removed, and the plate is folded into a substantially flat plate shape. The folded and used corrugated cardboard box is transported to a predetermined place for reuse or discarded, but in a normal corrugated cardboard box, the bottom and the lid are the same as the side wall surface. Moreover, since it is manufactured by bending one sheet of paper material, a large amount of material is required (bottom part and lid part), resulting in a large area when folded, and various processing and transportation are complicated.

Furthermore, the work of removing the sealing member is complicated, and moreover, when the lid is opened (removal of the sealing member), too much force is applied, and pressure is applied to the egg container that has been stored, so that the eggs inside May be damaged. Moreover, in practice, the removal of the sealing member damages the paper in that portion, which reduces the strength and makes reuse difficult.

The present invention has been made in view of the above background, and an object of the present invention is to easily open and transfer the stored package to a display shelf or the like, and to use it. An object of the present invention is to provide a collective packaging box body which has a small amount of paper material and can be reduced in size when the box body is crushed after use.

[0010]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, in the collective packaging box body according to the present invention, the side periphery of the article group including a plurality of packaging bodies arranged in at least one of the vertical direction, the vertical direction, and the horizontal direction is covered. A frame body having upper and lower openings is arranged. Then, the upper and lower openings of the frame are closed with a heat shrink film.

[0011]

[Action]

 Since the heat-shrinkable film is in a tension state, the tension of the heat-shrinkable film receives the plurality of packages housed in the frame body and suppresses the package body from being separated from the opening of the frame body.

On the other hand, the opening of the collective packaging box can be easily performed by cutting the heat-shrinkable film, especially the portion covering the opening. After opening, remove the frame and partition plate if necessary. Then, the plurality of packages remain in the arrangement state when they are stored in the frame. Therefore, a plurality of packages are taken out at the same time.

[0013]

【Example】

Hereinafter, preferred embodiments of the package according to the present invention will be described in detail with reference to the accompanying drawings. First, an egg container 10 which is an example of a package to be stored will be described with reference to FIGS. 1 to 3. The egg container 10 is made of transparent plastic and has a depth dimension l capable of accommodating a flat base portion 11 and an egg 12 (height dimension l ₀ , maximum width dimension d ₀ ) integrally molded with the flat base portion 11. And a container body 14 including a plurality of storage portions 13 having an opening dimension d, and a peelable film that is welded onto the peripheral portion of the flat base portion 11 of the container body 14 or is adhered with an adhesive or a pressure sensitive adhesive. And a sheet 15 in the shape of.

Further, in this embodiment, the container 13 having the arrangement of 5 × 2 rows (10 in total) is formed in one container body 14, and each container 13 is added to at least the egg 12. It has elasticity to absorb the shock from the up and down direction. Specifically, the cross-sectional shape of the storage unit 13 is substantially octagonal throughout, and is tapered so that the lower portion tapers, and when the eggs 12 are stored in the storage unit 13. The lower end of the egg 12 is held in contact with the tapered surface of the storage portion 13. Here, it is preferable to form a slight gap between the upper portion of the egg 12 stored in the storage portion 13 and the lower surface of the sheet 15 in order to prevent damage to the egg 12.

A partition wall 16 having a height dimension l ₁ that is less than half the height dimension l ₀ of the eggs 12 stored in each storage portion 13 is formed between the adjacent storage portions 13, 13. .. Thus, since the height of the partition wall 16 has a height dimension l ₁ that is less than half the height dimension l ₀ of the egg 12 stored in the storage portion 13, the egg 12 is manually or automatically robotized. This finger can be inserted between the storage parts 13 and 13 in a state of being gripped by the handle, and storage and removal can be facilitated. In this case, it is preferable that the plane distance between the adjacent storage portions 13 and 13 is also set to a size considering the ease of storing and taking out the eggs 12.

A peeling portion 18 having no adhesive force to the flat base portion 11 of the container body 14 is formed on the peripheral edge of the sheet 15. In this embodiment, the peeling portion 18 is formed in the one end region along the longitudinal direction of the sheet 15. In addition, perforations 17 that divide the plurality of storage portions 13 into two areas are formed on the sheet 15 along the direction orthogonal to the longitudinal direction. As a result, the peeling portion 18 is divided by the perforations 17. The sheet pieces 15a thus formed are formed at one end portions thereof.

The peeling portions 18 may be formed at both ends of each sheet piece 15 divided by the perforations 17, and when the perforations 17 are not formed on the sheet 15, the four corners of the sheet 15 are formed. It goes without saying that it may be formed only on any one of the four corners or the four corners. In addition, if a similar peeling portion is provided in at least one of the two corners where the peeling portion 18 is not formed, and the peeling portion is pinched and pulled up, the entire sheet 15 is temporarily cut regardless of the presence of the perforations 17. It may be formed so that it can be peeled off. This can be easily realized by forming each of the small holes forming the perforation 17 into a triangular shape and giving it directivity. Furthermore, the peeling portion 18 may have a weak adhesive force with the flat base portion 11 as long as it can be easily peeled from the container body 14.

The container body 14 having the above configuration is integrally molded by, for example, deep drawing. That is, while pressing a chip of a predetermined shape that fits the shape of the storage portion 13 from the upper surface side of a plastic planar sheet having a predetermined thickness (which constitutes the flat base portion 11 after molding), the lower surface is vacuumed. By suction, the storage portion 13 having a predetermined shape is integrally molded. In this way, the island portions 19 are formed between the four storage portions 13 by deep-drawing the plurality (10 in this embodiment) of the storage portions 13. In this case, the top surface of the island portion 19 is flush with the flat base portion 11.

Next, a first embodiment of the collective packaging box body according to the present invention for accommodating a plurality of the above-mentioned egg containers 10 will be described. That is, as shown in FIG. 4, in this example, an article group including a total of six egg containers 10 in the vertical and horizontal directions (horizontal direction), two in total, and a total of twelve egg containers 10 in upper and lower stages. It is designed to store and package 20. In addition, in this example, the flat base portion 11 of each egg container 10 is arranged so as to be located on the upper side at the time of storage, but it may be arranged on the lower side, or the both are mixed. You may do it.

Then, the above-mentioned article group 20 is arranged in a rectangular frame body 21 which is opened vertically. The height of the frame 21 is substantially equal to or slightly higher than the height of the egg containers 10 stacked in two stages. The frame body 21 is formed by forming a crease at an appropriate position in the longitudinal direction of a strip-shaped corrugated cardboard, and fixing both ends in the longitudinal direction of the corrugated cardboard by bonding or the like to form an endless shape.

Further, in this example, among the egg containers 10 arranged in the horizontal direction, a flat partition plate 22 is arranged between the adjacent egg containers 10 and 10, and each egg container 10 moves in the horizontal direction. Is suppressed. The partition plate 22 extends in the vertical and horizontal directions, and both ends of each partition plate 22 are in contact with the inner surface of the frame body 21.

In this example, since the egg containers 10 are arranged in both the vertical and horizontal directions as described above, the partition plates 22 are arranged in both directions as described above. Therefore, the partition plates 22 cross each other at a predetermined position. Therefore, in this example, a notch 22a is formed at the intersection from above or below toward the center, and the notches 22a are meshed with each other to be integrated (see FIG. 5).

Further, two rectangular shrink films 23, which are heat-shrinkable films, are arranged so as to cover the upper and lower openings of the frame body 21 accommodating a predetermined number of egg containers 10 and partition plates 22, The four sides of the two shrink films 23 are welded (sealing portion 23a), and heated to cause heat shrinkage. As a result, the shrink film 23 comes into close contact with the outer surface of the frame body 21, and the upper and lower openings of the frame body 21 are also tightly sealed.

Next, an example of a method of manufacturing the above-mentioned collective packaging box will be described. First, as shown in FIG. 5, an integrated partition plate 22 and frame body 21 are prepared. Then, the integrated partition plate 22 is inserted into the frame body 21, and the length of each partition plate 22 is substantially equal to the length of the long side or the short side of the frame body 21. Therefore, when the partition plate 22 integrated into the frame 21 is inserted, each end of the partition plate 22 comes into contact with or comes close to the inner peripheral surface of the frame 21 (see FIG. 6).

As a result, the six spaces 24 are defined by the frame body 21 and the partition plate 22, and the egg containers 10 are vertically stacked in twos in each space 24 with the plane base 11 facing upward. .. As a method of stacking the eggs, the egg containers 10 may be supplied into the space 24, or 12 egg containers 10 may be stacked and arranged at a predetermined position (3 × 2 × 2 stages). The procedure may be arbitrary, such that the frame 21 and the partition plate 22 may be supplied to the article group 20 from above.

When the partition plate 22 and the egg container 10 are inserted into the frame body 21 as shown in FIG. 7, they are placed on the carrier device 31 of the packaging device 30 as shown in FIG. 8 and transported. Then, a pair of original films 32, 32 around which the shrink film 23 is wound are arranged at the upper and lower positions on the carry-out end side of the conveying device (belt conveyor) 31, respectively. Then, the shrink films 23, 23 drawn out from the two original films 32, 32 are welded and integrated with each other at their leading end portions, and prevent the path of the frame body 21 transported on the transport device 31 from being blocked. It is located in. As a result, the frame body 21 transported on the transport device 31 abuts on the front ends of the shrink films 23 and 23 pulled out from above and below, and when the frame body 21 is further advanced in this state, both the shrink films 23 and 23 are removed. It is pulled out to close the upper and lower openings of the frame body 21. At this time, although not shown, both side edges of the two films in the advancing direction are welded by a vertical fusing sealer to form the film into a tubular shape.

Next, while the upper and lower openings are covered with the shrink films 23, 23, the fusion film sealing device 34 in the next stage melts and cuts back portions of both the shrink films 23, 23 in the advancing direction. The intermediate package 35 in which the frame 21 (egg container 10, partition wall 23) is hermetically housed in 23 is manufactured. Then, the intermediate wrapping body 35 is heat-shrinked by passing through the shrink tunnel 36 to manufacture a collective packaging box body as shown in FIG. Since the shrink film 23 is in a tensioned state, the egg container 10 is supported by the tension of the shrink film 23, so that the egg film 10 is torn to the outside by breaking the shrink film 23 from the opening of the frame 21. There is no. Therefore, the collective packaging box can be stored and transported as it is.

On the other hand, in order to display a plurality of egg containers 10 housed in the collective packaging box body manufactured as described above at a store or the like, the shrink film is simply opened by cutting it with a knife or other means. be able to. At this time, preferably, before opening, the collective packaging box itself is placed on a display shelf or the like and opened in that state. The shrink film that has been once torn can be further torn from the torn portion and can be removed from the frame body 21. Then, as shown in FIG. 7, the opening of the frame 21 is in a state before being covered with the shrink film.

When the frame 21 is removed in this state, the partition plate 21 and the egg container 10 remain on the display shelf as shown in FIG. Next, by removing the partition plate 21, only the egg container 10 remains on the display shelf as shown in FIG. That is, it is not necessary to transfer the egg containers 10 one by one.

In addition, the frame 21 and the partition plate 22 after use can be easily folded by tilting them in one direction, and when folded, there is no lid or bottom, so that the frame 21 and the partition plate 22 are compact. Further, since the frame body 21 and the partition plate 22 are not deteriorated in strength, there is no harmful effect on reuse.

In the above embodiment, the shrink film surrounds the entire circumference of the frame 21, but the present invention is not limited to this, and the frame 21 is opposed to the frame 21 as shown in FIG. 11, for example. The shrink film 23 'may not be present in the predetermined portion 39 to be formed (this can be manufactured without providing the vertical fusing seal device in the above-described embodiment). That is, it is sufficient that at least the upper and lower openings of the frame body 21 are covered.

The package housed in the frame 21 is not limited to the above-mentioned egg container, and the packaged object is not an egg but a food such as a fruit which is easily broken or has a substantially similar shape. Further, crafts other than food may be stored. Furthermore, the shape of the container itself is also arbitrary, and various packaging bodies such as a rectangular shape can be used.

Further, the number and the arranging direction of the packages to be housed in one collective packaging box body are not limited to those in the above-mentioned embodiments, and are completely arbitrary. The number of partition plates arranged is one to a plurality according to the number of packages arranged in the horizontal direction. Further, even when a plurality of partition plates are installed, it is not always necessary to integrate all the partition plates as in the above-mentioned embodiment, and particularly only one (vertical or horizontal) of the horizontal direction (up and down direction). If either one or plural arrangements are allowed), it becomes difficult to connect the partition plates to each other.

Further, the egg container is not limited to the one shown in the above embodiment, and for example, as shown in FIG. 12, eight embossed ribs 40 are provided in each storage portion 13 ′ along the vertical direction. It may be integrally molded (the impact from the side can be alleviated by using such a configuration), and various other modifications can be made.

Furthermore, the method of attaching the shrink film to the upper and lower openings of the frame body 21 is not limited to the one using the so-called sleeve wrapping device using the above-mentioned two original films, and for example, a pillow A wrapping device and various other means can be used, and the point is that the shrink film can cover both openings.

Further, in the above-mentioned embodiment, the partition plate 22 is simply inserted and arranged in the frame body 21, but the present invention is not limited to this, for example, as shown in an enlarged view in FIG. A cutout recess 21'a is provided at a predetermined portion of the upper end of the body 21 ', and projections 22'a are provided above both ends of the partition plate 22'. They may be integrated. Furthermore, as shown in FIG. 14, a window hole 21 "a is provided at a predetermined site on the side surface of the frame 21", and a projection 22 "a is provided at a central part of both ends of the partition plate 22". Various modifications can be made such that the two may be integrated by matching with the window hole 21 "a.

[Effect of the device]

 As described above, the collective packaging box body according to the present invention can be opened very easily by tearing the shrink film, and the packaging body side is not damaged. Moreover, a plurality of packages can be taken out from the collective packaging box at the same time by a simple operation such as removing the frame (partition plate) with the frame facing upward. Furthermore, since the lid and the bottom are made of shrink film, the frame and the like can be folded very compactly after use.
