DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for packaging tires for automobiles, etc., and a packaging body thereof.

(Prior Art) In general, as a method for packaging the above-mentioned tires, there is a method of wrapping the tire by wrapping it in a spiral around the entire circumference using paper tape, for example (for example, Japanese Patent Publication No. 59-9410, Japanese Patent Publication No. 59
−20531).

(Problems to be Solved by the Invention) The above packaging method is excellent in terms of protecting the entire tire, but it requires a lot of effort to pack, and when it is placed outdoors, there is a risk that rainwater may enter through the gaps between the tapes. There is. Furthermore, when purchasing tires, it is essential to directly check the tread pattern, shape, etc. Therefore, when displaying tires, it is necessary to peel off the wrapping paper. For this reason, when tires are displayed for a long period of time, dust etc. may enter the inside of the tire, and sometimes when installing the tire on the wheel, the important ear part and the top and bottom of the tire that come into contact when stacking tires. There are problems such as damage to the bulge on the side surface. Especially when displaying tires outdoors,
This effect is significant.

(Means for Solving the Problems) In view of the above, the present invention provides a packaging method and its packaging body that covers the inner peripheral part and both sides that require dustproofing and protection, and exposes the treads of the outer peripheral part. The purpose is to provide

In order to achieve the above object, the packaging method of the present invention is characterized in that (a) a cylindrical material made of synthetic resin is inserted into the inner hole of the tire, and (b) the axial direction of the material is By protecting the central part as a cylindrical part and pressing it against the inner surface of the tire's inner hole, the cylindrical part covers the entire inner opening of the tire. At the same time, by pressing the material in the axial direction with both pressing dies, each side of the material in the axial direction is heated and softened, and while expanding radially outward in a flange shape, each corresponding part of the tire is (d) forming a pair of flange portions that cover substantially the entirety of each corresponding side portion of the tire, including the bulging portion thereof, by deforming the tire in a curved shape along the side portions; The tire is disposed between the corresponding bulge on each side and the tread on the outer periphery, and (e) an opening is formed between the outer peripheries of both flanges to expose the tread on the outer periphery of the tire to the outside.

Furthermore, the packaging body of the present invention is characterized by: (a) being made of synthetic resin; (b) having a cylindrical portion that is fitted into the inner hole of the tire to cover the entire inner opening of the tire; (c) each flange portion has a pair of flange portions integrally protruding radially outward from each end of the shaped portion and covering substantially the entirety of each corresponding side portion of the tire including the bulging portion; , is formed in a curved shape along each corresponding side of the tire, and the outer peripheral edge of each flange portion is arranged between the bulge of each corresponding side bulge of the tire and the tread of the outer peripheral portion, and (e) both An opening is formed between the outer circumferential edges of the flange portion to expose the tread surface of the outer circumferential portion of the tire to the outside.

(Function) The package protects the inner opening of the tire, the bulges and ears on both sides, and the tread on the outer circumference of the tire.
Exposed to the outside. Therefore, even when the tire is being transported and displayed, it is possible to prevent rainwater from entering the inside of the tire, and to prevent damage to various parts other than the tread surface due to impact or the like. Additionally, tires can be displayed in their packaging.

(Embodiment) FIGS. 1 to 3 show a first embodiment of the present invention. The tire 1 opens toward an inner hole 2, and ears 3 and 4 are formed on both sides of the opening to be pressed against a flare part (not shown) formed on the wheel, and treads 5 of various shapes are formed on the outer periphery. , both sides 6, 7
is formed in a bulge shape outward in the axial direction.

The package 10 for the tire 1 includes a cylindrical part 11 that fits into the inner hole 2 and covers the entire inner opening 8 of the tire, and a cylindrical part 11 that integrally projects radially outward from both ends of the cylindrical part 11. It consists of flange parts 12 and 13 provided. Each flange portion 12, 13 is
It is curved in a shape that follows the bulges of the ears 3, 4 and side parts 6, 7 of the tire 1, and has an outer diameter that exceeds the bulges of the side parts 6, 7, and has a diameter that exceeds the bulges of the side parts 6, 7. The tread surface 5 is dimensioned to be exposed.
Each flange portion 12, 13 covers substantially the entire corresponding side bulge 6, 7 including the bulge portion, and its outer peripheral edge is formed of the bulge portion of each side portion 6, 7 of the tire 1 and the tread surface of the outer peripheral portion. An opening is formed between the outer peripheral edges of both the flange parts 12 and 13 to expose the tread surface 5 of the outer peripheral part of the tire 1 to the outside.

FIG. 3 shows a schematic diagram of a packaging device for attaching the package 10 to the tire 1. This packaging device 2
0 includes an upper mold 21, a lower mold 22, and a tire holding arm 23. The upper mold 21 and the lower mold 22 are each inserted into the inner hole 2, and have fitting parts 25, 28 that press and hold the material W against the inner hole surface, and pressing parts 26, 29 that oppose the tire side parts 6, 7. The press molds 24 and 27 are provided with suitable heating means 30 and 31 connected to the press molds 24 and 27. 32 and 33 are heat insulating members, 34 is a guide tube attached to the upper mold 21, and a guide hole 35 provided in the lower mold 22.
to be inserted into.

In the above configuration, the tire 1 is held by the tire holding arm 23, and after the cylindrical material W having a synthetic resin film is fitted into the inner hole 2 at a proper position, it is transferred between the upper and lower molds 21 and 22. Next, while heating the pressing molds 24 and 27 of both the upper and lower molds 21 and 22, they are moved close to the tire 1 side. As a result, the material W
is softened by heating, expands outward in the radial direction into a flange shape, is held between the press molds 24, 27 and the tire side parts 6, 7, and forms an opening for the inner hole 2 of the tire 1, as shown in FIG. 8 and both sides 6,
A package 10 deformed along 7 is formed and its shape is maintained by cooling.

In addition, although the above-mentioned material W has been shown as an example in which it is made into a cylinder shape in advance, instead of this, a flat material is fitted into the inner hole of the tire, and both ends are overlapped, and the overlapping parts are welded to form a cylinder shape. You can also use it as

Next, FIGS. 4 and 5 show a second embodiment of the present invention. In this embodiment, a package is manufactured in advance and assembled into the tire 1.
0 consists of an upper packaging member 41 and a lower packaging member 42. Each of them is made of a relatively hard synthetic resin by the above-mentioned heat molding or injection molding, and has a cylindrical portion 4 that fits into the inner hole 2 of the tire 1.
3 and 44, and flange portions 45 and 46 that follow the shape of the side portions 6 and 7 of the tire 1. Cylindrical part 4
The total length of the cylindrical parts 43 and 44 is the same as or slightly shorter than the distance between the outer sides of the ear parts 3 and 4 of the tire 1, and an overlapping part 47 is formed in either one of the cylindrical parts 43 and 44.

The flange portions 45 and 46 are formed to have a diameter that covers the tire side portions 6 and 7, as in the previous example.

As a result, as shown in FIG. 5, the tire 1 is sandwiched from both sides, and the overlapping part 47 and the other cylindrical part 44 that fit therein are welded or joined using an appropriate adhesive tape (not shown). When using the latter adhesive tape, it is convenient when removing the package.

(Effects of the Invention) According to the present invention, the entire inner opening of the tire and substantially the entire side portion including the bulging portion can be tightly covered along the outer shape of the tire. When transporting and exhibiting tires, it is possible to prevent rainwater and dust from entering inside the tires, and also to prevent damage to the tires due to external shocks.

In addition, an opening is formed between the outer peripheral edges of both flanges of the package to expose the tread of the outer circumference of the tire to the outside, so that when the tire is wrapped in the package,
Through the opening of the package, it is possible to directly see the pattern, shape, etc. of the tread on the outer periphery of the tire, and even step on the tread.

Furthermore, since the outer periphery of each flange is placed between the bulge on each corresponding side of the tire and the tread of the outer periphery, the radial middle part of each flange, rather than the outer periphery, is aligned with the axis of the tire. It is located at the outermost position in the direction of the heart. Therefore, even though the outer periphery of each flange is used as the edge of the opening, when the tire is handled in a packaged state, the outer periphery of each flange may curl up due to contact with other objects. There is less risk that the tire will become incompletely packaged due to dryness.

Further, in the tire packaging method of the present invention, tires can be extremely easily packaged as described above using a cylindrical material made of synthetic resin.
