The applicant of the present invention has previously integrated a radial packing piece outward from the central seat portion as a packaging tool for softly wrapping a fruit such as peach or melon whose surface is easily damaged. An extended sheet-shaped packaging tool was proposed. This sheet-like wrapping device is formed by vacuum forming a sheet-like product, thereby lifting the seat portion and forming the radial wrapping piece inwardly via the inversion sloping portion, so that the object to be packaged is When it is placed on the seat portion, the seat portion descends, the reversal inclined portion is reversed, and the packaging piece wraps the article to be packaged with one touch.

The wrapping device having the above structure can wrap the objects to be wrapped with one touch, is easy to manufacture, and is easy to stack because it is sheet-like, which is very convenient and convenient for storage, storage and transportation. It is expensive. The present invention has been proposed for the purpose of further increasing the usefulness of such a sheet-shaped packaging tool.

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a perspective view showing an example of the packaging tool of the present invention, FIG. 2 is a sectional view showing a state in which apples are packaged by the packaging tool shown in FIG. 1, and FIG. 3 is an enlarged sectional view of a synthetic resin foam sheet material. FIG. 4 is a cross-sectional view showing a method for producing a synthetic resin foam sheet-like product, and FIG. 5 is a cross-sectional view showing a state in which a cut surface is formed on the synthetic resin foam sheet-like product.

The packaging tool 10 shown in FIGS. 1 and 2 is made of a synthetic resin foamed sheet material 20. As described in the above-mentioned section of the prior art, the sheet material is vacuum-molded to form a central part. The seat portion 11, the inverted slope portion 12, and the packaging piece 13 are integrally molded. This wrapping tool 10
As shown in the figure, particularly, softly wraps the object to be packaged M such as fruits (apples in this example).

The synthetic resin foam sheet material 20 used in the wrapping tool 10 of the present invention is a flexible synthetic resin foam sheet material for softening the impact on the object to be packaged and softly wrapping the shape. Is used. As the synthetic resin foam sheet material 20, for example, a soft sheet material mainly composed of synthetic resin foam such as polyethylene, polypropylene, polystyrene and polyurethane is suitable.

As will be better understood from FIG. 2 and FIG. 3 which is a partially enlarged view of this packaging device 10, the surface on the side of the packaging surface in contact with the article M to be packaged constitutes the sheet-like material 20. The cut surface 21 of the synthetic resin foam and the outer surface are formed by the self-skin layer 22 of the synthetic resin foam.

With this structure, the cut surface 21 on the side of the encapsulating surface exposes the internal air bubbles (cells) s by cutting the synthetic resin foam and forms an uneven surface. Therefore, the friction on the packaging surface side becomes large, and as a result, the holding property for the object to be packaged becomes high, and the object M to be packaged slips or rotates in the packaging tool (so-called ball rotation).
Can be prevented from being damaged. At the same time, the unevenness of the wrapping surface improves the water absorption and air permeability of the wrapping surface. Therefore, moisture or the like on the surface of the object to be packaged M is not accumulated on the wrapping surface of the wrapping tool 10, and the object to be packaged M rots (for fruits or the like) or rusts (for metals or the like).
Can be prevented.

On the other hand, the self-skin layer 22 formed on the outer surface is a fine and dense layer formed at the time of molding the synthetic resin foam, so that the cut surface 21 is formed.
In comparison with, it has lower surface rigidity and water repellency. As a result, not only can the package M be elastically packaged along the shape thereof, but also external moisture can be prevented from seeping into the packaging tool 10 and damaging the package M.

The structure of the packaging tool 10 of the embodiment will be briefly described below. The central seat portion 11 is a portion on which the bottom portion of the article M to be packaged is placed, and is formed substantially at the center of the packaging tool 10.
In the embodiment shown in FIG. 1, the central seat portion 11 is formed in a substantially circular shape. However, in addition to a substantially elliptical shape according to the shape of the object to be packaged, the central seat portion 11 has a polygonal shape such as a substantially triangular shape and a substantially square shape. May be. Further, the central seat portion 11 is provided with ribs 14 in order to enhance the cushioning property and heat retaining property (cold retaining property) and its rigidity (hip strength) at the bottom of the packaged object. In this example, it is a circular rib formed concentrically on the central seat 11.

The inversion sloping portion 12 is extended from the central material portion 11 to the lower outer side with an inclination, and lifts the central seat portion 11 upward when no articles are packaged in the packaging device 10. The inverted slope portion 12 is formed by the central seat portion 11
It is configured to reverse inward as descent of
By placing and pressing the article M to be packaged on the lifted central seat portion 11, the article M is quickly turned inward (turned over).

Further, in order to give the reversing inclined portion 12 further rigidity and to invert it more reliably and effectively, radial vertical ribs are provided along the reversing inclined portion 12. You may form. By providing the radial vertical ribs, it is possible to enhance the cushioning property and the heat retaining property (cold retaining property) in the vicinity of the lower portion of the packaged item after being inverted.

Further, although not shown in the drawings, in order to efficiently invert the inversion inclination portion 12 to the inside, the central seat portion 11 is formed.
It is desirable to form the boundary between the inversion sloped portion 12 and the inverted slope portion 12 to be thin. When the central seat portion 11 is pushed down, this thin-walled boundary portion becomes a fold, so that the inversion inclination portion 12 can be inverted reliably and efficiently.

The wrapping piece 13 is lifted up by the reaction when the inversion sloping portion 12 is inverted inward, and the curved shape of the wrapping piece 13 softly wraps and wraps the article M to be packaged. 12 and extends radially outwardly and integrally. Furthermore, the tip is formed in a concave shape that curves inward so that it can be wrapped along the outer shape of the article. The packing pieces 13 are formed in an appropriate number, width, length and shape depending on the shape and size of the packaged object. Further, a rib or the like can be provided on the packaging piece 13.

The packaging 10 of the embodiment is manufactured by a known molding method, but vacuum molding, press molding and the like are preferable in terms of moldability and economy.

A method of manufacturing the synthetic resin foam sheet material 20 applied to the packaging tool 10 will be described. First, the synthetic resin foam material is introduced into a predetermined mold to mold the synthetic resin foam 20A. At this time, as shown in FIG. 4, the self-skin layers 22, 22 made of fine and dense bubbles are formed by the synthetic resin foaming raw material itself in the portion in contact with the mold surface.

The synthetic resin foam 20A is shown in FIG.
By cutting from the cutting line C-C of FIG. 5, two sheets of synthetic resin foam sheet 20, 20 are obtained as shown in FIG. As described above, the obtained synthetic resin foam sheet material 20 is formed into a predetermined packaging tool shape such that the cut surface 21 is on the side of the object to be packaged by known vacuum forming or press forming as described above.

[0021]

As shown and described above, according to the packaging tool of the present invention, since the surface of the packaged surface of the object to be packaged is composed of the cut surface of the synthetic resin foam sheet,
Not only shock-absorbing properties but also appropriate water absorption is imparted, and there is no possibility that moisture or the like discharged from the article to be packaged will be accumulated in the packaging tool and damage the article to be packaged. In addition, since the outer surface is made of a self-skin layer, waist strength and water repellency are imparted, and articles inside can be protected and reliably packaged.
