DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wrapping device, and more particularly to a soft wrapping device capable of softly wrapping individual articles to be wrapped with one touch.

[0002]

2. Description of the Related Art In order to protect fruits, ornaments, daily necessities, precision products or various parts from impacts and damages on the surface, various kinds of packaging materials for individually and almost completely wrapping the outside of the article to be packaged. It has been known. The present applicant has previously proposed a sheet-like packaging material made of a soft synthetic resin foam capable of softly wrapping fruit such as peach and melon with one-touch operation (for example, Japanese Patent Application No. Hei.
No. 249851).

However, in the case of this type of sheet-like packaging material made of a soft synthetic resin foam, moisture scattered from or adhered to the article to be packaged accumulates at the bottom of the packaging material during storage or transportation. There is a risk of damaging the packaged item.

[0004] On the other hand, a mesh-shaped wrapping material can be mentioned as a solution to such a problem. However, this mesh-shaped wrapping material is continuously manufactured by special extrusion molding, and then is formed into an appropriate length. Since it is formed by cutting, there is a tendency that large-scale molding equipment is required in manufacturing and the cost is increased. On the other hand, even a user who uses this requires a complicated operation of opening the open mesh portion of the mesh-like packaging material, pushing the article into a predetermined position, and housing the article.
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.

[0005]

FIG. 16 is a cross-sectional view of a vacuum forming die for forming the packaging device of the present invention, and FIG. 16 is a cross-sectional view of a molded product obtained by using the forming die.

As shown in FIGS. 1 to 4, a packaging device 20 according to the present invention is made of a soft sheet material 21 mainly composed of a synthetic resin foam, and is integrally provided on a central seat portion 22 and outside thereof. And a wrapping portion 24.

First, as the soft sheet material 21 used for the packaging device 20 of the present invention, a flexible sheet material that wraps the surface of an article to be packaged such as fruit softly without damaging it is used. For example, a sheet material mainly composed of a synthetic resin foam made of polyethylene, polypropylene, polystyrene, polyurethane, or the like is a suitable material. If necessary for the article to be packaged, a composite laminated sheet material in which another foamed or non-foamed sheet material or a mesh material is laminated and adhered to a synthetic resin foam may be used.

The center seat portion 22 is formed substantially at the center of the packaging tool 20, and the upper surface thereof forms an article mounting surface 30 on which the bottom of the article to be packaged is mounted. In the illustrated embodiment,
Although the center seat portion 22 is formed in a substantially circular shape, it may be formed in a substantially elliptical shape, a substantially triangular shape, a substantially square shape, a substantially polygonal shape, or the like, as necessary, in relation to the article to be packaged.

On the upper side of the central seat 22 (article mounting surface 30), there is provided a linear radial groove 25 for containing moisture that may accumulate in the seat. The radial groove 25 is formed linearly outward from the center of the central seat 22 as shown in FIG. It is sufficient that the depth of the radial groove 25 is about 2 to 3 mm and the width is about 5 mm. In addition,
As shown in the enlarged sectional view of FIG.
If 25B is a gentle slope, the drainage of the seat 22 surface is further improved.

As can be clearly understood from the sectional view of FIG. 4 and the enlarged sectional view of FIG. 6, the central portion of the radial groove 25 is formed lower than the outer peripheral portion so as to drain quickly and efficiently. You can also. In this case, as shown in FIG. 6, since the outer peripheral portion 22 </ b> A of the central seat portion forms the article mounting surface 30 that holds the article T to be packaged, the article T comes into contact with the drained water W. There is no.

Further, as shown in FIGS. 1, 3 and 4, a through hole 32 is provided at the center of the radial groove 25 so that water collected in the radial groove 25 is discharged to the outside. You may.

Further, it is more effective to provide an outer peripheral groove 34 communicating with the radial concave groove 25 on the outer periphery of the upper surface of the center seat 22 to improve the drainage of the outer periphery of the center seat.

Next, the reversing inclined portion 23 will be described. As shown in the sectional view of FIG. 4, the reversing inclined portion 23 raises the central seat 22 upward and lowers the central seat 22 as the central seat 22 descends. It extends from the center seat portion 22 to the lower outside so as to be inclined so as to be inverted. This inverted inclined portion 23
Is reversed when the article to be packaged is placed on the lifted central seat portion 22 and the bottom portion thereof is pressed down to descend downward (inversion)
It is configured in a dome shape with a gentle slope as shown in FIG.

Note that, in order to impart rigidity to the reversing inclined portion 23 so that the inversion is reliably and effectively performed in the inward direction, a radial vertical portion is formed along the inclined portion 23. Preferably, ribs 27 are formed. In addition to this, the radial vertical ribs 27 also have the advantage of improving the buffering property and the heat retaining property (cooling property) near the lower part of the article to be packaged after the reversal.

Further, as means for reliably and efficiently inverting the inversion inclining portion 23 inward, an annular thin portion 29 is formed along the boundary between the central seat portion 22 and the inversion inclining portion 23. Is effective. That is, as is well understood from the cross-sectional view of FIG. 4, when the central bottom portion 22 is pushed down D by the substantially circular thin portion 29 formed at the boundary between the central seat portion 22 and the inverted inclined portion 23, This thin portion 29 becomes a fold line to form the inverted inclined portion 23.
Can be reliably and efficiently performed. The annular thin portion 29 is formed on the outer surface 20a of the wrapper as shown in FIG. 8, in addition to the one 29A formed on the inner surface 20b as shown in FIG. 9, or on both inner and outer surfaces as shown in FIG. What is formed on 20a, 20b 29
There is B.

As shown in FIGS. 1 to 4, a plurality of wrapping portions 24 are radially and integrally extended outward from the reversing inclined portion 23, and are formed in an open petal shape as shown in the drawing. It is formed. The wrapping portion 24 is formed in an appropriate number, width, length, and shape according to the shape and size of the article to be packaged. In addition,
The wrapping part 24 is desirably formed in a concave shape whose tip is curved upward so as to wrap the upper part of the article. The wrapping portion 24 is provided with the reversing inclined portion 2.
3 inward with the reversal of 3, and as a result, as shown in FIG.

The wrapping portion 24 may be provided with a rib 28 in the longitudinal direction. The ribs 28 have the advantage of providing the wrapping portion 24 with stiffness and increasing the cushioning property and the heat retaining property (cooling property) on the side surface and the upper portion of the article to be packaged at the time of packaging. The ribs 28 of the wrapping portion 24 and the vertical ribs 27 of the reversing inclined portion 23 may be formed continuously as shown in FIGS.

The wrapping portion of the wrapping device of the present invention is a wrapping portion 2 comprising a plurality of petal-shaped wrapping pieces as in the above-mentioned wrapping device 20.
In addition to 4, like the wrapping portion 64 of the packaging tool 60 shown in FIG. 11 and FIG. In these figures, reference numeral 61 denotes a sheet-like object, 62 denotes a central seat,
Reference numeral 65 denotes a radial groove, 67 denotes a radial rib provided on the inverted inclined portion 63, 69 denotes a thin portion, 72 denotes a through hole, and 74 denotes an outer peripheral groove.

The wrapping portion 64 is folded inward in accordance with the size and shape of the article to be wrapped as shown in FIG. It completely wraps around. As shown in the figure, when the ribs 68 are provided in the longitudinal direction of the wrapping portion 64, in addition to the function described in the previous wrapping tool 20, the folding of the tip of the wrapping portion with the reversal of the reversing inclined portion 63 is performed. The effect as a margin for facilitating is further added.

Although the packaging device of the present invention is manufactured by a known molding method, vacuum molding is preferred and advantageous from the viewpoint of moldability and economy. 14 to 16 show an example of the production. The flexible sheet base 40 made of a synthetic resin foam shown in FIG. 14 is formed into a sheet by a known means, and is heated in advance, appropriately softened, and placed in a vacuum forming die 50.

As shown in FIG. 15, the vacuum forming die 50 includes a lower die 51 and an upper die 52, and has a predetermined center seat,
