DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on specific embodiments shown in the accompanying drawings.

FIG. 1 is an exploded view of a package for a spherical heavy goods. In this case, the package contains a melon. It goes without saying that the present invention can be carried out with paper, cardboard or other thin sheet material instead of paperboard. If it is cardboard, it will not be subject to the obligation to re-commerce because the recycling system has already been established under the Containers and Packaging Recycling Law that came into effect on April 1, 2000. In this embodiment, an example using cardboard will be described.

[0008] On a substantially rectangular corrugated cardboard, a circular curve r is engraved with a diameter smaller than the diameter of the melon to be supported, and a radial cut from the center of the circular curve r to the circular curve r is engraved. To provide a square upper support panel J on which a plurality of fan-shaped flaps G are formed. In order to easily fit the melon, a circular curve s concentric with the circular curve r and having a radius of about a half is engraved.

The cuts are shifted so that the flap G does not come to the center of the bent curves b and c on the four sides of the upper support panel J. This prevents the package from breaking from the cut. Otherwise, the upper support panel J, the side panel B, and the upright panel C cannot be neatly folded at right angles.

A square side panel B is connected to the left and right sides of the upper support panel J with a folding curve b interposed therebetween.

On the left side of the left side panel B, a square bottom panel F having substantially the same size as that of the upper support panel J is folded along a curve m.
And intervene.

In order to adhere to the lower portion of the inner surface of the side panel B, a square intermediate glue margin K is connected to the left side of the bottom panel F with a folding curve o interposed.

On the left side of the intermediate glue allowance K, a circular folding curve t having a smaller diameter than the circular folding curve r of the upper support panel J is engraved.
The middle support panel I of a square having substantially the same size as the upper support panel J in which a plurality of fan-shaped flaps H are formed by providing radial cuts from the center of the circular fold curve t to the circular fold curve t is provided. .

In order to adhere to the middle of the inner surface of the side panel B, a margin L is connected to the left side of the middle support panel I with a folding curve u interposed.

An upright panel C is connected to the upper and lower sides of the upper support panel J via folding curves c.

An L-shaped pushing piece D is provided at a corner of the upright panel C and the side panel B. The L-shaped push-in piece D includes a folded portion N and a bent portion M. The folded portion N is connected to the standing panel C with a folding line p interposed therebetween, and the bent portion M is folded to the side panel B. It is connected with the curve q interposed. The connection between the fold line N and the bent portion M is connected by a fold line d with a perforation.

The insertion piece E is connected to the upright panel C with a folding curve e interposed therebetween.

A bent piece A is connected to the middle support panel I with a bent curve a interposed therebetween.

The assembly of this package will be described.

First, an adhesive is applied to the inner surface of the paste allowance L and the outer surface of the intermediate paste allowance K by a box making machine.

Next, the inner surface of the adhesive margin L is adhered to the intermediate inner surface of one side panel B, and the outer surface of the intermediate margin K is adhered to the lower inner surface of the other side panel B.

In this state, the package is delivered in a folded state.

When using this package, first, the side panel B is erected vertically.

Next, the bent piece A is mountain-folded at the bent curve a and vertically lowered.

Subsequently, the L-shaped pushing piece D is wrapped around the inner surface of the upright panel C while the folding line d is valley-folded, and the inserting piece E is inserted and locked inside the bottom panel F.

When the melon is placed on the flap G, the flap G and the flap H are each folded inward (downward), and the assembly is completed. The lid used is of a generally used type. The upper and lower ends of the bottom panel F support the lid.

According to the present invention, as shown in FIG. 2, a heavy spherical product is floated and supported by a double face of the intermediate support panel I, the flap H and the upper support panel J, and the flap G.

By forming the bent piece A to be a vertically upright surface, a structure for more strongly supporting the force applied to the intermediate support panel I is provided. Also, when you put the product, flap H,
A series of flaps G form a surface that wraps the sphere, and that surface firmly supports the product.

As shown in FIG. 3, if the flap G and the flap H are not provided, the product is supported by the line such as the circular folding curve t and the circular folding curve r, and the supporting force is weakened.
In addition, more than half of the product cannot be wrapped, resulting in poor stability.

The cuts of the flaps H and G are shown in FIG.
As shown in (2), by shifting in the radial direction, a surface that wraps the sphere in a mesh shape can be created, and the product can be stably supported.

As shown in FIG. 5, a cut T was adopted in the arc curve so that the upper support panel J, the flap G, the middle support panel I and the flap H would not be broken by weight. The load is dispersed at the cut T.

Further, a push-in piece D was attached so as to be easily and beautifully assembled.

As shown in FIG. 6, only by pushing the pushing piece D in contact with the side panel B inward, the upright panel C naturally falls down to facilitate assembly. Also, the assembled corners are beautiful with no visible cross section of the paper.

The general structure of the prior art has a structure as shown in FIG. 7. In this structure, the cross section is visible and unsightly and not suitable for gifts.
