DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging material, and more particularly to a flexible packaging material capable of softly wrapping an article to be packaged with one touch.

[0002]

2. Description of the Related Art In order to protect an object to be packaged from impact or damage to its surface, various types of packaging materials for individually and individually packaging the object to be softened have been used. For example, in the case of packaging melon, a mesh-like packaging material made of a soft synthetic resin foam is used. This mesh-shaped wrapping material is continuously manufactured by a special extrusion molding, then cut into an appropriate length, and a melon is pushed into the inside and used.

However, such a mesh-like packaging material requires a complicated operation in which a user who uses the mesh-like packaging material opens the opening of the packaging material and pushes the article into a predetermined position to house it. Further, when storing and transporting the mesh-like packaging material, although it is folded, it is considerably bulky and has disadvantages in storage and transportation.

DISCLOSURE OF THE INVENTION The present invention has been proposed in view of the above problems, and does not require any complicated work, can easily pack articles, and has a shock absorbing property. An object of the present invention is to provide a sheet-like packaging material having high performance. Still another object of the present invention is to provide a packaging material which can be stacked as a sheet during storage and transportation and saves space.

[0005]

That is, the present invention provides:
Consists of a soft base sheet mainly composed of synthetic resin foam,
A substantially central portion of the base sheet is formed so as to be reversible as a circular convex portion, and the wrapping pieces that are lifted upward by the reversal of the circular convex portion and wrap around the article are radially integrated with each other. The present invention relates to a packaging material, wherein a rib that extends and is integrally formed with a rib protruding toward the outer surface side of the wrapping piece.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a plan view showing an example of the packaging material of the present invention,
FIG. 2 is a cross-sectional view thereof, FIG. 3 is an end view of the packaging material in a state where the article is not wrapped, and FIG. 4 is an end view showing an inverted state of the packaging material when the article is wrapped.

As shown in FIGS. 1 and 2, the packaging material 10 of the present invention is formed of a soft base sheet 11, and has a circular convex portion 12 and an wrapping piece 20 extending radially from the circular convex portion 12. It is composed of

As the soft base sheet 11 used for the packaging material 10 of the present invention, a flexible sheet material that wraps an article to be packaged such as fruit softly without damaging it is preferable, for example, polyethylene, polypropylene, or the like.
A sheet material mainly composed of a synthetic resin foam made of polystyrene, polyurethane, or the like is preferable. Note that a composite laminated sheet can also be used.

The circular convex portion 12 is formed at a substantially central portion of the packaging material 10 and, when not wrapping an article, rises and protrudes to the side where the article to be packaged comes into contact. The circular convex portion 12 is formed in a hemispherical surface (dome shape) so that when an article is placed on the circular convex portion and pressed, the pressure is reversed by the pressure.

A plurality of wrapping pieces 20 are radially and integrally extended from the circular convex portion 12 and formed in a petal shape as shown in the figure. An article to be packaged is placed on the wrapping material 10 on the wrapping piece 20, and the circular convex portion 12 is placed on the back side 10a of the wrapping material.
By reversing the shape, an object is automatically lifted upward by the reaction and wraps around the article. The number of the wrapping pieces 20 formed on one wrapping material 10 is appropriately set according to the size and shape of the article to be wrapped, and is 12 in this embodiment.

The wrapping piece 20 is integrally provided with a rib 25 formed so as to protrude in the length direction of the wrapping piece 20 and toward the outer surface side. This rib 2
5 not only enhances the cushioning properties of the packaging material and buffers shocks from the floor surface or adjacent articles, but also imparts elasticity to the wrapping piece 20 to increase the packaging force of the packaging material 10. Also,
When the inner surface side of the rib 25 is formed as a concave groove as in the embodiment, an air layer is formed between the article and the wrapping piece 20 by the concave groove, so that heat insulation and cold insulation can be enhanced. . The ribs 25 are formed in an appropriate number and length depending on the size and shape of the article to be packaged and the number of the wrapping pieces 20, and in this example, the twelve wrapping pieces 20 are used.
Of these, as shown in the figure, the wrapping pieces are provided on every other wrapping piece 20a.

The wrapping piece 20 preferably has a tip 21 formed in a concave shape 22 that curves upward. Thereby, when the wrapping piece 20 is inverted, the whole article can be securely wrapped.

Referring to FIGS. 3 and 4, a state in which an article is packaged using the packaging material of the present invention will be described. Packaging material 10
An article to be packaged M such as an apple is placed on the circular convex portion 12. The circular convex portion 12 is depressed by the weight of the article M and automatically reversely protrudes to the opposite side of the packaging material. Thereby, the plurality of wrapping pieces 20 formed around the circular convex portion 12 are lifted up as shown by the arrow in FIG. 3, and the article can be wrapped with the wrapping material with one touch.

At this time, since the ribs 25 project from the outer surface of the wrapping piece 20, the wrapping piece 20 has elasticity at the time of reversing, that is, so-called stiffness, so that not only can the article be wrapped securely but also in the outward direction. It has high cushioning against impact from

When the inner surface side of the rib 25 is formed as a concave groove as in the embodiment, the article M and the rib 25 are formed.
Since an air layer is formed between the air conditioner and the air conditioner, the article can be protected from an external temperature change. Furthermore, as in this example, when the tip of the wrapping piece 20 is formed in the concave strip 22, the spherical article M can be softly wrapped along its shape.

[0016]

As shown and described above, according to the packaging material of the present invention, packaging can be carried out with one touch only by placing an article on the packaging material. Therefore, packaging can be performed simply and reliably without any complicated work. Further, since the packaging material of the present invention is provided with the ribs on the outer surface side, it is possible to provide high shock-absorbing properties and a covering power for articles. Furthermore, since it can be stacked, it can be used very advantageously without requiring a large space during storage and transportation.
