  The packaging material 10 which concerns on one Embodiment of this invention shown in FIGS. 1-3 consists of the sheet-like object 11, and is provided with the center seat part 20, the inversion inclination part 30, and the covering piece 40. FIG. The packaging material 10 is suitable for packaging a package M that is relatively easily damaged such as fruits such as peaches, apples, pears, vegetables such as tomatoes, and substantially spherical fruits and vegetables.

  The sheet-like material 11 is formed of a material that has flexibility that can wrap the article to be packaged M, and has protection and buffering properties that suppress damage to the surface thereof. The sheet-like material 11 mainly comprises a known synthetic resin foam such as polyethylene, polypropylene, polystyrene, polyurethane, etc. in order to obtain excellent heat retention (coldness) in addition to flexibility, protection, and buffering properties. The following materials are preferably used.

  This packaging material 10 is manufactured by well-known vacuum press molding from a viewpoint of a moldability or economical efficiency. In vacuum press molding, a suction device such as a vacuum pump is connected to upper and lower molds having mold surfaces corresponding to a predetermined shape of the packaging material 10, and a preheated sheet is placed in the mold for vacuum suction. Is called. Thereby, a sheet-like object is closely_contact | adhered to the mold surface of an upper and lower metal mold | die, and a predetermined shape is provided. Thus, by performing vacuum press molding, a fine shape can be easily formed on the sheet-like material.

  The center seat 20 is a portion on which the bottom of the article to be packaged M is placed when the packaging material 10 is unfolded, and is provided at a substantially central portion of the packaging material 10 as shown in FIGS. The central seat portion 20 has a shoulder portion 21 having an arc shape when viewed from the side at a connection portion with a reverse inclined portion 30 described later, and a seat surface portion 25 is formed above the shoulder portion 21 via an annular step portion 22. The shape of the seating surface portion 25 is a substantially circular shape corresponding to the shape of the article to be packaged M because the substantially spherical fruits and vegetables are wrapped as the article to be packaged M.

  As shown in FIGS. 2 to 4, the inversion inclined portion 30 lifts the central seat 20 upward and reverses inward with the lowering of the central seat 20. It is extended and inclined to the lower part outside via. The inversion inclination part 30 is wrapped around the outer periphery of the article to be packaged M in a state of being bent inward by reversal (turning over), and protects the outer periphery of the article to be packaged M.

  In this inversion inclination part 30, as shown in FIGS. 1-4, the some rib 35 is radially formed in the outer surface side. In the embodiment, the rib 35 is a ridge that projects the sheet-like portion of the inversion inclined portion 30 outward. Further, as shown in FIG. 3, the plurality of ribs 35 are formed such that two ribs extend in substantially the same direction, and the two ribs are radially formed as one set. By forming the plurality of ribs 35 on the reversing inclined portion 30, the reversing inclined portion 30 is given a low strength, and the reversal in the inner direction is reliably and effectively performed. Further, since the sheet-like portion of the inversion inclined portion 30 protrudes outward, a space is formed between the inner surface side of the rib 35 and the article to be packaged M when being wrapped to the article to be packaged M. For this reason, the buffering property at the time of packaging and heat insulation (cold insulation) property can be improved. In this embodiment, the rib 35 is formed from below the shoulder portion 21 of the central seat portion 20 to the covering piece 40 described later.

  As shown in FIGS. 2 and 3, the wrapping piece 40 is formed in a shape in which a plurality of pieces are radially integrated with each other outward from the inversion inclined portion 30. The wrapping piece 40 is attached to the periphery of the article to be packaged M in accordance with the inversion of the inversion inclined part 30, and protects the article to be packaged M together with the inversion inclination part 30. The covering pieces 40 are formed in an appropriate number, width, length, and shape according to the shape and size of the article to be packaged M, and are, for example, about 8 to 12 pieces. In the illustrated example, 12 wrapping pieces 40 are formed radially.

  As shown in FIGS. 1, 2, and 4, a curled claw portion 45 is formed at the tip of the covering piece 40. The curled claw portion 45 is folded back toward the back surface of the sheet-like material and folded outward when the reversing inclined portion 30 is reversed. As shown in FIGS. 1 and 5, the curled claw portions 45 are arranged so as to be continuous in a circumferential shape over the entire circumference of the article to be packaged M when the packaging material 10 is reversed. Therefore, the part attached to the article M to be packaged including the curled claw part 45 from the inverted inclined part 30 has a shape imitating a petal such as a tulip, and the appearance and design are improved.

  In the packaging material 10 of the present invention, as shown in FIGS. 1 and 4, the central inclined portion 30 is inverted through the shoulder portion 21 of the central seat portion 20 so that the central seat portion 20 bulges downward. The pedestal 50 is formed. The pedestal portion 50 is a part for enabling the packaging material 10 to be self-supporting when the article to be packaged M is wrapped. In this pedestal portion 50, as shown in FIGS. 4 and 6, an annular leg portion 55 is formed at the lower outer edge portion.

  Here, the formation process of the base part 50 by the inversion of the inversion inclination part 30 is demonstrated. As shown in FIG. 7A, the article M to be packaged placed on the central seat portion 20 is pressed against the seat surface portion 25 and pushed downward, thereby pushing the central seat portion 20 downward. When the center seat 20 is further pushed in by the article to be packaged M, the inversion inclined portion 30 is inverted via the shoulder 21 as shown in FIG. 7B, and the center seat 20 is interposed via the shoulder 21. Thus, the base 50 is formed by bulging downward. At that time, as shown in FIGS. 2 and 3, the rib 35 is formed below the shoulder portion 21. That is, since the rib 35 is not formed on the shoulder portion 21, the reversal through the shoulder portion 21 is smoothly performed, and the central seat portion 20 (the pedestal portion 50) is appropriately bulged.

  The pedestal portion 50 shown in FIG. 7B is a pedestal-shaped bulged portion 50 </ b> A in which the seat surface portion 25 is grounded to the floor portion F. In the pedestal-shaped bulging portion 50A, the annular step portion 22 forms a lower outer edge portion, and is in a state of floating upward from the floor portion F as illustrated. On the other hand, the seat surface portion 25 is in a state where it protrudes downwardly from the annular step portion 22 in a convex shape. After the reversal of the reversing inclined portion 30, as shown in FIGS. 5 and 7 (b), the bottom portion of the package M is placed on the annular placing portion 26 corresponding to the reversing portion of the shoulder portion 21. Is done. Since the annular mounting portion 26 is formed in an annular shape (circular shape) corresponding to the shape of the central seat portion 20, that is, the spherical shape of the object to be packaged M, the object to be packaged M is stabilized at the time of packaging. Can be placed.

  As described above, after the reversal inclined portion 30 is reversed, as shown in FIG. 7C, the load on the package M is loaded by placing the package M on the annular mounting portion 26. In addition to the annular mounting portion 26, the annular step portion 22 is lowered with respect to the seat surface portion 25. At this time, the seating surface portion 25 is deformed from a downward convex shape to a concave shape (upward convex shape) by reversing the curve. Thereby, the annular step portion 22 corresponding to the lower outer edge portion of the pedestal portion 50 (pedestal-shaped bulging portion 50A) is grounded to the floor portion F and formed as an annular leg portion 55. Thus, since the lower outer edge portion of the pedestal portion 50 is grounded annularly by the annular leg portion 55, the self-supporting stability of the pedestal portion 50 is improved.

  As shown and described above, the packaging material 10 of the present invention is made of a sheet-like material mainly composed of a synthetic resin foam, and the inverted inclined portion 30 and the plurality of covering pieces 40 are connected by the inversion of the inverted inclined portion 30. Since it adheres to the outer periphery of the article to be packaged M, the article to be packaged M can be effectively protected and kept warm (cold).

  Moreover, since the inversion inclination part 30 inverts through the shoulder part 21 of the center seat part 20, since the center seat part 20 is formed as the base part 50 which bulges downward, it is easy to be independent in the packaging material 10. Can be granted. Further, since the curled claw portion 45 is formed at the tip of the wrapping piece 40, the curled claw portion 45 folded back outwardly over the entire circumference of the article M during wrapping is circumferential. Arranged in a line. Therefore, the overall shape of the packaging material 10 can be a shape simulating a petal, and excellent appearance and design can be imparted.

  In addition, the packaging material of this invention is not limited only to the above-mentioned embodiment, A part of structure can be changed suitably and implemented in the range which does not deviate from the meaning of an invention.

  As described above, with the packaging material of the present invention, it is possible to satisfactorily protect an object to be packaged such as fruits and vegetables that are easily damaged, and to be placed independently. Therefore, it can be easily placed on a display shelf or the like, and the occurrence of products falling or falling can be reduced. Moreover, since it is excellent in design property, it can give a good impression to consumers and is expected to promote purchase intention.
