Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a packaging tool used when selling spherical fruits and vegetables such as watermelons, melons, and pumpkins.

[Conventional technology]

Normally, watermelons are traded in their harvested spherical form, but because one piece is too large and expensive, and it is difficult to tell the ripeness of the contents from the outside, only half of the watermelons are sold at the retail stage. It is also sold by cutting it into pieces of 4 to 10 pieces.

By the way, when watermelon is sold cut, the cut surface of the watermelon is covered with a polyethylene film (wrap) and displayed at the store for hygiene reasons or to prevent it from drying out. The cut surface of a watermelon is often pressed with one's fingers, which causes dents to form on the cut surface and the pulp at the edge-shaped top of the watermelon to crumble, resulting in a decrease in product value.

In order to solve these drawbacks, conventional
- In No. 177388, a hard synthetic resin sheet formed in a substantially circular shape is tilted in cross section from the diameter line position.
A packaging tool has been proposed which is folded in half to form a shape, and each of the left and right parts covers the cut surface of the watermelon.

[Problem that the invention attempts to solve]

However, with the above-mentioned conventional packaging tool, when the cut surface of the watermelon is covered, the entire back side of each piece of the sheet is attached to the cut surface of the watermelon, so it is difficult to press the diametrical position of the folded sheet with your fingers. In this case, the force is applied to the edge-shaped top of the watermelon through the sheet, and as a result, there is a risk that the pulp at the top cannot be prevented from collapsing. Since it is not easy to fold the sheet, it is difficult to bend the sheet to fit the divided shape of the watermelon, and therefore it takes a long time to cover the cut surface of the watermelon.

The present invention was developed to solve the above-mentioned drawbacks of the conventional technology, and even if you press the diametrical position of a folded sheet with your fingers, the force will not be transmitted to the edge-like top of the watermelon through the sheet. To provide a packaging tool which makes it easy to bend the sheet from the diametrical position of the sheet to a bending angle suitable for the divided shape of watermelon.

[Means to solve the problem]

In order to achieve the above object, the present invention is a packaging device in which a substantially circular synthetic resin sheet is folded in half from the diametrical position, and each of the left and right parts covers the cut surface of the watermelon. In this step, a certain width on both sides of the sheet that is in contact with each other through the diameter line is raised to the surface side of the sheet at that location to form a bulge, and the diameter line position that is the boundary between these bulges is In this case, the sheet is further raised toward the surface side at the location to form a narrow convex portion.

[Effect]

With the above structure, by folding the sheet in half from the diameter line position of the convex part and attaching each of the left and right parts so as to overlap the cut surface of the watermelon, the convex part and both sides thereof can be folded. At the bulging part, there is a gap between the back surface of the sheet and the cut surface of the watermelon, and in addition to the above-mentioned parts, the back surface of the sheet is in close contact with the cut surface of the watermelon, covering the cut surface of the watermelon. Become.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In Figs. 1 to 3, reference numeral 1 denotes a hard synthetic resin sheet formed into a substantially circular shape and having an appropriate thickness, and whose cross section is from the diameter line D. By folding it in half to form an inverted V shape, the left and right pieces 1', 1' can cover the cut surface of the watermelon S; In order to sometimes see the degree of ripening of the cut surface through the sheet 1, the sheet 1 is made of polypropylene or the like and is colorless or transparent. 2, 2 is the bulge, and the diameter line D
The sheet 1 is formed by raising the sheet 1 toward the surface side at a certain width point on both sides that are in contact with each other through the As shown in FIG. 3, the rounded step portions are continuous. 3 is a narrow convex portion formed by further protruding the sheet 1 of a predetermined width at the diameter line D position, which is the boundary between the two bulging portions 2, 2, toward the surface side to have a semicircular cross section. . The ratio of the width of each of the bulges 2, 2 and the convex portion 3 to the size of the sheet 1 depends on the size of the watermelon to be divided, but for example, if the sheet 1 is formed into a slightly oval shape, In the case of dimensions in the direction of diameter line D, that is, the diameter dimension is about 270 mm and the short axis dimension is about 240 mm, the bulging parts 2, 2 should be set to about 15 mm each, and the convex part 3 should be set to about 10 mm. Good.

4, 4 are reinforcing protrusions provided along the arcuate edges of each piece 1', 1' by raising the sheet 1 near the edges toward the surface side. This prevents the arcuate edges of each piece 1', 1' from curling back when covering the cut surface of the watermelon S. 5 is the diameter line D
This is a perforation cut along the diameter line D in order to make the bending at the position easier. Also, 6, 6 is the convex portion 3 at the diameter line D position.
There are handle attachment holes protruding from each other at appropriate intervals.

In order to package watermelon by the piece using the packaging tool described above, fold the sheet 1 in half from the diameter line D of the convex portion 3, and then wrap the left and right pieces 1', 1' into the watermelon S.
Attach it so that it overlaps the cut surface. By doing this, as shown in FIG. 3, a gap G exists between the back surface of the sheet and the cut surface of the watermelon S at the convex portion 3 and the bulging portions 2, 2 on both sides thereof. The other parts than the above-mentioned parts cover the cut surface of the watermelon S with the back surface of the sheet in close contact with the cut surface.

After attaching each piece 1', 1' to the cut surface of the watermelon S, attach several parts of the arcuate edges of each piece 1', 1' to the bottom of the watermelon S using adhesive tape T prepared separately. The sheet 1 is fixed to the watermelon S by fastening. Further, a string H for carrying a handbag is inserted into the handbag attachment holes 6, 6 in advance to attach the string H to the seat 1.

If you do the above, you can carry the cut watermelon by hanging it on the string H, so there is no need to put the cut watermelon in a separate packaging bag with a carrying handle when you take it home, and therefore you can sell it at the store. can be done hygienically and efficiently.

FIG. 4 shows another embodiment of the present invention, which differs from the previous embodiment in that the protruding pieces 7 facing toward the back side along the arcuate edges of each piece 1', 1' of the sheet 1, 7 was established. Each of the protruding pieces 7, 7 is formed so that as it approaches the end of the diameter line D position, the length of the protrusion toward the back surface from the edge becomes gradually shorter. When folded in half from position D, cover the cut surface of the watermelon S with each piece 1', 1' so that the tips of the protruding pieces 7, 7 do not come into contact with each other on the sides near both ends. We make sure that there are no hindrances to this. 8, 8 is the protruding piece 7,
The reinforcing protrusion provided at 7 is formed by protruding a predetermined width of the protruding piece toward the back side.

When carrying out as described above, each part 1',
Not only will the edges of the watermelon 1' be further strengthened, but when each piece covers the cut surface of the watermelon S, each protruding piece 7, 7 will be located at the bottom of the watermelon S. The bottom of the watermelon is supported from both sides by the protruding pieces, so even if the watermelon is sold by the piece, it can be carried by holding it up without fear of it falling.

Note that the sheet 1 is formed to match the size of the watermelon to be divided, but usually, by preparing several types of sheets of different sizes, it can be made compatible with most watermelons sold by the piece.

Furthermore, in the above example, a string is used as a handbag, and the string is attached to the seat by passing it through the hand attachment hole, but the structure of the handbag and the means for attaching it to the seat are not limited to this. do not have.

[Effect of idea]

As is clear from the above description, according to the present invention, when the sheet is folded in half from the diameter line position of the convex part and the left and right pieces cover the cut surface of the watermelon, the convex part and At the bulges on both sides, there is a gap between the back of the sheet and the cut surface of the watermelon, so even if you press the diameter line of the folded sheet with your fingers, the force will be applied to the sheet. There is no risk of the water being transmitted to the edge-shaped top of the watermelon via the watermelon, and therefore the edge-shaped top of the watermelon, which tends to crumble, can be reliably protected.

Moreover, since the diameter line position is formed as a narrow convex part, when the sheet is folded from the diameter line position, the convex part acts as a hinge, so the sheet is folded in half from the diameter line position. It is easy to bend, and the surface of the cut end of watermelons of various sizes can be quickly covered during packaging.
