Description

[Detailed Description of the Invention] The present invention relates to a package, and particularly to a package suitable for packaging fruits and the like.

Conventionally, this type of packaging uses soft foam sheets such as urethane foam, cardboard/lz4 cardboard, or an independent air chamber as a cushioning material between the top and bottom of the packaged items such as fruits packed in multiple layers. Plastic sheets having a large number of protrusions (hereinafter referred to as protrusion sheets) have been used in appropriate combinations.

Therefore, when packing boxes, it takes a long time to load these cushioning materials, and since the items to be packaged, such as fruits, are stored one by one, it is difficult to arrange them on store shelves. In some cases, the product has to be taken out of the packaging box, placed on a tray, and then wrapped in a plurality of pieces with plastic film by stretch wrapping or shrink wrapping.

An object of the present invention is to provide a packaging body in which an item to be packaged is placed on a tray and wrapped with a plastic film.

Hereinafter, details of the present invention will be explained along with embodiments shown in the drawings.

First, the protrusion sheet used in the package according to the present invention will be explained.

Fig. 1 explains a conventional protrusion sheet, and the protrusion sheet, which is designated as a whole by reference numeral 1, is a plastic film 3 on which a number of protrusions 2 constituting independent air chambers are formed. It is made by pasting a film 4. When films 3 and 4 are pasted, the air inside the protrusion 2 cannot escape and becomes an independent air chamber, and when an object is placed on the protrusion 2, the protrusion 2 becomes elastic. It can be deformed and provide a sufficient cushioning effect.

However, such a single-layer protrusion sheet 1 does not have a sufficient vertical cushioning effect to withstand long-distance transportation.

In order to obtain a sufficient buffering effect, the inventor of the present invention
A composite cushioning material 5 as shown in the figure was adopted.

The composite cushioning material 5 shown in FIG. 2 consists of a protrusion sheet 7 having a large protrusion 6 and a protrusion sheet 9 having a small protrusion 8. A protrusion sheet 9 is attached with the protrusions 8 attached thereto.

The height of the large protrusion 6 is 8-20m/m, the base area is 3-15m
0m2 is appropriate.

The thickness of the composite cushioning material 5 including the protrusion sheet 9 having small protrusions is 10 to 35 m/m, preferably 1
2 to 20 m/m is suitable.

Since this embodiment is configured as described above, the vertical buffering effect is increased due to the synergistic effect of the buffering effects of the large protrusion sheet 7 and the small protrusion sheet 9, respectively.
At the same time, the honeycomb effect of the small protrusions 8 of the small protrusion sheet 9 adds to the overall stiffness.

In the embodiment shown in FIG. 3, a buffer sheet 10 made of cardboard, cardboard, or a soft foam sheet such as urethane foam is adhered to the side surface of a protrusion sheet 7 having large protrusions 6 opposite to the protrusions 6 to provide composite cushioning. It is made of wood 5, and the strength of the waist can be further increased.

In the embodiment shown in FIG. 4, the projection 8 side of a projection sheet 9 having smaller projections 8 is attached to the back surface of the cushioning sheet 10 of the composite cushioning material 5 shown in FIG. and,
The buffering effect is further increased.

By the way, what is shown in FIG. 5 is an inner package, and this inner package 11 is a tray 12 formed into a dish shape from a semi-rigid synthetic resin sheet, a synthetic resin foam sheet, etc., and a packaged object 13 such as a fruit is placed on the tray 12. The tray 12 and the tray 12 are stretch-wrapped or shrink-wrapped using a plastic film 14, and the number of items 13 to be packaged to be accommodated is not limited to two, but may be any number.

Next, a packaging method using the above-mentioned members will be explained.

FIG. 6 is a longitudinal side view illustrating the packaging state, in which a composite cushioning material 5 is placed at the bottom of a packaging box 15 made of cardboard or a plastic sheet, with its large protrusion 6 facing downward. A plurality of internal packaging bodies 11 are arranged on top of the inner packaging bodies 11, and a composite cushioning material 5 is placed on top of these internal packaging bodies 11 with its large protrusion 6 facing downward. Array.

In this way, the internal packaging bodies 11 are stacked in multiple stages with the composite cushioning material 5 sandwiched between them, and the composite cushioning material 5 is placed on top of the inner packaging body 11 in the topmost stage with its large protrusion 6 facing downward. Then close the lid.

Note that if a cushioning material 16 made of a protruding sheet, a soft foam sheet, etc. is attached to the inner circumferential surface of the packaging box 15, the inner packaging body 11 and the inner surface of the packaging box 15 can prevent the load from coming into direct contact with each other. No damage will occur.

As is clear from the above description, according to the present invention, with a plurality of items to be packaged placed on a tray, the inner package wrapped in plastic film is sandwiched vertically between the protrusion sheets having large protrusions. Since the structure is such that the packaged items are stored in the packaging box in an unprotected state, even when transported over long distances, the damage to the packaged items is at most 5% or less, which is practically negligible. There are only two types of materials, a composite cushioning material and a packaging box, which are economical because they are small in number, and the packaging work is simplified.

For example, if the above-mentioned inner packaging items are arranged directly inside the packaging box and stacked and stored without using any of the composite cushioning materials, it is possible to The left and right vibrations disrupt the arrangement and stacking of the internal packages stacked inside the packaging box, and the internal packages collide directly with each other, causing damage. In contrast to fruit, etc., which is severely damaged, in the packaging of the present invention, the inner packaging is sandwiched vertically by the composite cushioning material, so that the inner packaging that is stacked in multiple tiers can be easily arranged and stacked. There is almost no chance of damage to the packaged items (fruit, etc.) as the internal packaging does not directly collide with each other due to vertical vibrations due to the presence of the composite cushioning material. There are very few.

In addition, the inner packaging packaged on the tray can be sold as is at the store, eliminating the need for repackaging, and since the inner packaging containing multiple items is packed into a box, the packaging work is greatly reduced. It has excellent effects such as being shortened to .
