Description

[Technical Field]

[0001] The present invention relates to a packaging device capable of individually wrapping fruits and vegetables such as peaches, pears, and grapes, sweets, and easily damaged or fragile precious metals and electronic components (hereinafter collectively referred to as "items"). [Background technology]

[0002] There have been various types of packaging devices for wrapping articles. Packaging devices for wrapping perishable fruits include those made of foamed resin. Examples are disclosed in Patent Documents 1 to 5.

[0003] The packaging devices of Patent Documents 1 to 5 are designed so that when an item, such as fruit or vegetable, is dropped onto the central portion (seat) of the upwardly protruding mountain-shaped container from a few millimeters to a few centimeters above, the container sinks and the outer side of the container bends inward (inverts), automatically wrapping the fruit or vegetable from the outside. However, the packaging devices of Patent Documents 1 to 5 have the drawback that even if fruit or vegetable is dropped onto the container, the outer side of the container is difficult to invert inward, and the fruit or vegetable is not wrapped securely.

[0005] To provide a packaging device in which, when an article is dropped onto the seat, the outer side of the seat is smoothly turned inward, and the dropped article is automatically wrapped from the outside. [Means for solving the problem]

[0006] The packaging device of the present invention is a packaging material that can wrap and package an item, and includes a flat base on which the item can be placed, a ring-shaped bent portion surrounding the outer periphery of the base, a base portion extending around the entire outer periphery of the bent portion, and a plurality of elongated packaging strips that are continuous with the base and protrude outward from the base. The base, bent portion, base, and packaging strips are a single piece that flares outward from the base, with the surface that faces the item when the item is packaged being the inner surface, and the surface that faces outward being the outer surface. The packaging strips are divided from the base side to the tip side. When the inner surface of the base is facing upward and protrudes upward, the inner surface of the bent portion also protrudes upward, and the inner surface of the base faces upward and curves gradually downward from the bent portion toward the packaging strip, and the inner surface of the packaging strip curves gradually downward from the base side and gradually upward toward the tip side. In this state, when an item is dropped from the seat onto the inner surface of the seat that protrudes upward, or when an item is pushed into it, the weight or pushing force of the item pushes down the seat and the bent part, causing them to invert so that they protrude outward, and as they invert, the base and the inner surface of the wrapping piece invert and stand up so that they curve inward, and the tip side of the wrapping piece faces upward, allowing the item to be wrapped. [Effects of the Invention]

[0007] The packaging device of the present invention has an inner surface of the seat that protrudes upward, and an article is automatically packaged simply by dropping or pushing the article onto the seat, which has the following effects. (1) Packaging work becomes easier. (2) When the inner surface faces upward and the seat and the bent portion protrude upward, and an article is dropped into the seat, the article is automatically wrapped, making it easier to automate the wrapping process. (3) If the packaging material is made of resin and can be mass-produced, costs can be reduced. [Brief explanation of the drawings]

[0009] (Embodiment 1) A first embodiment of the present invention will be described with reference to Figures 1 to 8. The packaging device 1 in Figure 1 is made of foamed resin and can be used to wrap the outer periphery of an article (for example, peaches) P for packaging.

[0010] As shown in Figure 2, the packaging device 1 in Figure 1 comprises a flat seat 2 large enough to place an item P on, a bent portion 3 provided on the outer periphery of the seat 2 so as to surround the seat 2, a base 4 extending outward from the outer periphery of the bent portion 3, and multiple packaging pieces 5 that are continuous with the base 4 and protrude outward from the base 4.

[0011] As shown in Figure 3(a), the base 2, the bent portion 3, the base 4, and the wrapping piece 5 are made of a single piece of foamed resin that flares out from the base 2 to the tip 6 of the wrapping piece 5. When this wrapping device 1 wraps an item P as shown in Figure 1 (when wrapping an item), the surface facing the item P is the inner surface 7, and the opposite surface is the outer surface 8.

[0012] In Figure 2, the inner surface 7 faces upward and the outer surface 8 faces downward, with the seat 2 and the bent portion 3 protruding upward. In this case, the inner surface of the bent portion 3 is flat, one step lower than the upper surface of the seat 2, the inner surface of the base 4 (the upper surface in Figure 2) gradually slopes downward from the bent portion 3 side toward the packaging piece 5 side, and the inner surface of the packaging piece 5 (the upper surface in Figure 2) gradually slopes downward from the base 4 side and curves gradually upward toward the tip portion 6 of the packaging piece 5.

[0013] [seat] The seat 2 (Fig. 2) is the portion on which the bottom of the item P is placed, and is formed in approximately the center of the packaging device 1. Although it is approximately circular in Fig. 2, it can be any shape that makes it easy to place the item P to be packaged. For example, if a single bunch of grapes is to be placed, an oval shape large enough to fit the single bunch would be appropriate. Alternatively, it can be any shape, such as an approximately triangular, approximately rectangular, or approximately polygonal, to match the shape of the item P.

[0014] [Bend] The bent portion 3 is a portion that assists the reversal when the bent portion 3 is reversed from a state in which it protrudes upward together with the seat 2 as shown in Figures 2 to 4(a)(b) to a state in which the inner surface 7 faces inward and the outer surface 8 faces outward as shown in Figures 5 to 7(a)(b). For this reason, in Figures 2 to 4(a)(b), the bent portion 3 is one step lower than the seat 2 and is flat, but when reversed, it protrudes to the outside (below) of the seat 2 and becomes a ring-shaped protrusion that surrounds the outer periphery of the seat 2 as shown in Figures 5 to 7(a)(b). During this reversal, the inner surface of the bent portion 3 becomes a groove-like recessed ring as shown in Figures 7(a)(b).

[0015] [base] The base 4 extends around the entire outer periphery of the bent portion 3 and is a portion that is turned over together with the seat 2 and the bent portion 3 when they are turned over, thereby assisting the turning over of the packaging piece 5 .

[0016] [Packaging piece] The packaging piece 5 extends outside the base 4 and is divided into several pieces from the base 4 side to the tip 6, with a separation space 9 between adjacent packaging pieces 5. Each packaging piece 5 is a long, narrow piece.

[0017] [rib] A series of ribs (hereinafter referred to as "circumferential ribs") 10 are formed from the tip 6 side of each packaging piece 5, passing through the base 4 and reaching the bent portion 3 side (Figs. 4(a) and 5). As shown in Fig. 8, the peripheral ribs 10 are recessed on the inner surface (upper surface in Fig. 8) 7 side of the packaging piece 5 and are convex strips that protrude in an arc shape on the outer surface (lower surface in Fig. 8) 8 side. Both outer sides 11 of the peripheral ribs 10 are flat. By adopting the above-described structure, the peripheral ribs 10 can assist the bent portion 3, base 4 and packaging piece 5 in inverting (turning upward).

[0018] In Figure 5, the width of the peripheral rib 10 is the same or approximately the same as the width of both outer sides 11, but it is desirable to design the width dimension, protrusion dimension, etc. to a size that makes it easy to perform the above-mentioned functions. The shape, length, position, etc. of the peripheral rib 10 may be other than that shown in the figure as long as it can achieve the various functions described above. For example, the cross-sectional shape may be triangular, horizontally elongated oval, or other shapes. Although only one peripheral rib 10 is shown provided in the center of the width direction of the packaging piece 5, two or more ribs may be provided parallel to each other in the width direction of the packaging piece 5.

[0019] It is desirable to design the shape, width, length and thickness of the seat 2, bending portion 3, base 4, and packaging piece 5, the width and shape of the separation space 9 between adjacent packaging pieces 5, and the width, number and length of the peripheral ribs 10 so that the item P can be easily packaged and the packaging device 1 can be easily turned over.

[0020] [Packaging material] In the above embodiment, the packaging device 1 is made of foamed resin. While polyethylene, polypropylene, polystyrene, polyurethane, etc. are also suitable, materials other than foamed resin may be used as long as they are easy to package the item P, have cushioning properties to protect it, and are reversible. For example, a composite laminated sheet material in which another foamed or non-foamed sheet material or mesh material is laminated onto a synthetic resin foam, or paper may be used if possible.

[0021] [Inversion: Packaging] When an article P is dropped onto the seat 2 (several mm to several cm above) which protrudes upward as shown in Figure 2, the weight of the article P presses the seat 2 down as shown in Figures 7(a) and (b), causing the bent portion 3 to invert and protrude downward as shown in Figures 5 and 6. At this time, the bent portion 3 becomes a circular ring-shaped protrusion as shown in Figures 6 and 7(b). As the seat 2 and bent portion 3 invert, the base 4 and wrapping piece 5 also invert and stand up. At this time, the peripheral rib 10 of the wrapping piece 5 also inverts, assisting the inversion of the base 4 and wrapping piece 5. The article P is then wrapped (packaged) by the inverted seat 2, bent portion 3, base 4, and wrapping piece 5 as shown in Figure 1.

[0022] (Embodiment 2) A second embodiment of the present invention will be described with reference to Fig. 9. The packaging device 1 in Fig. 9 is the same as that of the first embodiment in terms of basic configuration, structure, materials, etc., except that a rib 13 (hereinafter referred to as "seat rib") is provided on the seat 2.

[0023] The seat rib 13 is long and thin and continues from the center of the seat 2 to the inner peripheral surface 3a (Fig. 9) of the bent portion 3, and is continuous with the peripheral rib 10 which is continuous with the outer peripheral surface 3b (Fig. 9) of the bent portion 3, sandwiching the bent portion 3. The seat rib 13 is a convex ridge that is recessed on the inner surface side of the seat 2 and protrudes to the outer surface (bottom surface), and its cross-sectional shape is arc-shaped like the peripheral rib 10 in Fig. 8.

[0024] The provision of seat ribs 13 makes it easier for the seat 2 to reverse from a state in which the inner surface of the seat 2 protrudes upward as shown in Figures 2 to 4(a)(b) to a state in which the inner surface curves inward as shown in Figure 5. In addition, the cushioning properties of the seat 2 are improved, so that when an item P is dropped onto the seat 2 that protrudes upward as shown in Figures 2 to 4(a)(b), the impact on the item P is mitigated, making it less likely that the item P will be damaged.

[0025] The seat ribs 13 can also be designed as desired in terms of length, width, adjacent spacing, cross-sectional shape, protruding dimensions of the ribs, etc., so that the seat 2 can be easily turned over and cushioning properties can be improved. For example, the cross-sectional shape can be triangular, horizontally elongated oval, or other shapes. Two or more parallel ribs can also be provided in the width direction.

[0026] (Embodiment 3) In FIG. 9, the seat rib 13 is continuous with the inner peripheral surface 3a of the bent portion 3, but it may also be separated from the inner peripheral surface 3a. [Industrial Applicability]

[0027] The packaging device of the present invention may have other structures as long as the inner surface 7 and outer surface 8 of the packaging device 1 are reversible. As shown in Figure 2, an example has been described in which an item P is dropped onto the protruding seat 2 facing upward, causing the inner and outer surfaces to reverse under the weight and wrap the item P, but the inner and outer surfaces can also be reversed to wrap the item P by holding the packaging device 1 in one hand with the seat 2 and bent portion 3 facing upward and pushing the item P into the seat 2 of the packaging device 1.
