Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a collective package, and more particularly to a collective package in which several packages are housed in a tray, and the tray and packages are surrounded by a shrink film.

Conventionally, as shown in FIG. 5, a collective package has been provided, in which several thin box-shaped trays contain several packages, and the tray and packages are surrounded by a shrink film. However, in conventional products with such a structure, the tray is thin and box-shaped, so when the tray and the wrapped item are surrounded by a shrink film, the contraction force of the shrink film may cause the shrink film to collapse or cause the wrapped item to collapse. There was a drawback that things deformed. Further, when a large number of assembled packages are stacked and stored or transported, there is a drawback that the wrapped items are crushed or come into contact with each other and are damaged.

The present invention solves the above-mentioned conventional drawbacks, and by making the tray have a special structure, even if a large number of collective packages are stacked and stored or transported, the packaged items will not be damaged. It is a collective package that prevents any collapse or damage, and its gist is that side plates of approximately the same height as the packaged items are erected on opposite side edges of the substrate, and Several encapsulations are placed on a substrate on a tray with partitions on both sides of which the outer peripheries of the encapsulations are placed in close contact with each other in the center of the top surface, and the outer peripheries of these encapsulations are placed on a tray. The assembled packaging is housed in contact with a partition, and the tray and the packaged items are surrounded by a shrink film.

Embodiments of the invention will now be described in detail in the accompanying drawings.

FIG. 1 is a perspective view of a tray used in the present invention, FIG. 2 is a partially cutaway perspective view of a collective package, FIG. 3 is a perspective view of a tray showing another embodiment, and FIG. 4 is a further FIG. 3 is a perspective view of a tray showing an embodiment of the invention.

The collective package of the present invention uses a tray 1 as shown in FIG. As shown in the figure, the tray 1 is made up of a substrate 2, a side plate 3, and a partition 4, and the side plate 3 is provided upright at the opposite side edge of the substrate 2 at approximately the same height as the packaged object 5. By erecting the side plates 3 in this way, the packages 5 will not collapse, and even if stacked, the packages 5 will not be crushed. The substrate 2 and side plate 3 are illustrated as simple plate-shaped ones. Although not shown, a recess or a through hole may be provided therein. In particular, it is preferable if the side plate 3 is provided with a recess or a through hole, since this makes it easier to grip. Also,
At the center of the upper surface of the substrate 2, there is provided a partition 4 on both sides thereof, which has concave portions into which the outer circumferential surfaces of several enclosures can fit, and is approximately the same height as the side plates. The partition body 4 is oriented approximately at right angles to the side plate 3,
An example is shown in which uneven portions 6 are formed on both sides. If such a partition body 4 is installed upright,
Several enclosures 5 are arranged on both sides of the partition 4,
And it can be delivered reliably. Note that the tray 1 in which the substrate 2, side plate 3, and partition body 4 are integrally formed is shown as an example. The tray 1 is made of, for example, synthetic resin foam, and as shown in FIG. 2, several packages 5 are placed on the substrate 2 of the tray 1. Further, the outer circumferential surfaces of several envelopes 5 are placed in a tray 1 with the outer peripheral surfaces thereof abutting against the partition 4, and the tray 1 and the envelopes 5 are surrounded by a shrink film 7.

The invention is not limited to what has been described above. For example, it may be a tray 1 as shown in FIGS. 3 and 4. FIG. 3 exemplifies a tray 1 in which guide grooves 8 are carved on the surfaces that come into contact with the shrink film when it is surrounded, for example, the side edges of the substrate 2 and the upper and side edges of the side plates 3. There is. When the guide groove 8 is carved in this way, the shrink film 7
becomes easier to cleave. In addition, the tray 1 shown in FIG. 4 has several cylindrical partitions 4 erected in the center of the upper surface of the substrate 2 at appropriate intervals and in a direction approximately perpendicular to the side plate 3. The outer circumferential surface of each cylindrical partition body 4 comes into contact with the outer circumferential surface of each cylindrical partition body 4. Furthermore, an engagement opening 9 is formed in the upper surface of the partition 4, and a handle 10 is engaged with the engagement opening 9. With such a device, the handle 10 can be attached to the board 2 by engaging the handle 10 with the engagement opening 9, making it convenient to carry.

As described above, in the present invention, several packages are placed in a tray, and the tray and packages are surrounded by a shrink film. Since this tray has side plates that are approximately the same height as the objects to be covered on the opposite side edges of the substrate, the contraction force of the shrink film is applied to the substrate and the side plates, and the objects to be covered are supported by the side plates. This prevents the load from collapsing or deforming the packaged items, and when storing or transporting a large number of stacked packages, the load is applied to the side plates, so the packaged items can be prevented from collapsing. There's no need to worry about being crushed. In addition, a partition body is provided on both sides of the central part of the top surface of the substrate, and the outer circumferential surface of the packaged object is placed in close contact with the partition body. This has many advantages, such as preventing the partition from moving erratically and preventing damage due to contact between enclosed objects during transportation.
