Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called shrink package, which is coated on the outer surface of an automobile and shrinks when heated so as to adhere tightly to the automobile.

0002

2. Description of the Related Art Generally, as a packaging method for transporting manufactured automobiles, so-called shrink packaging is used, in which the entire automobile is wrapped in heat-shrinkable packaging. That is, in this packaging method, the entire outer surface of an automobile is covered with a heat-shrinkable wrapping material, and then heat is applied to the heat-shrinkable wrapping material to bring the wrapping material into close contact with the automobile. By the way, when transporting a manufactured automobile, a method is adopted in which a worker drives the automobile himself and loads it onto a freight car, cargo ship, or the like. However, such a shrink-wrapped car has the disadvantage that it cannot be put inside the car after being wrapped.

[0003] For this reason, various shrink-wrapping methods have been proposed so far that the car can be ridden even after packaging (for example, Japanese Patent Publication No. 50-1883
(See Publication No. 7).

[0004] Furthermore, the packaging material used for heat-shrink wrapping automobiles is a uniaxially stretched film that shrinks only in the longitudinal direction of the automobile so that the automobile can be shrink-wrapped in close contact with the automobile.

[0005]

[Problems to be Solved by the Invention] However, in the case of the above-mentioned conventional packaging, the entire film is stretched in the vehicle length direction due to shrink wrapping. That is, the package comes into close contact with protrusions such as the side, roof, front end, and rear end of the vehicle. Therefore, since the package is pulled between the roof and the front end of the concave portion in front of the windshield, a film surface that is different from the inclination angle of the windshield is formed.

[0006] As a result, when getting into a shrink-wrapped car and driving the car, inconveniences may occur such as reflection of light rays on the film surface, difficulty in seeing ahead, and inability to drive safely. Become.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a heat-shrinkable package that can be shrink-wrapped with a good view of the front from the driver's seat.

[0008]

[Means for Solving the Problems] The heat-shrinkable packaging for an automobile of the present invention is a packaging that is coated on the outer surface of an automobile and that shrinks when heated to come into close contact with the automobile. A uniaxially stretched film that can be heat-shrinkable in the vehicle width direction is used at least in the portion that covers the area in front of the upper end of the windshield.

[0009] The area in front of the upper end of the windshield refers to the entire portion covering the automobile from the upper end of the windshield to the front bumper. However, if a uniaxially stretched film that can be heat-shrinkable in the vehicle width direction is used at least in the front vehicle width portion of the entire portion that covers the vehicle from the upper end of the windshield to the front bumper,
It is possible to shrink the package in front of the driver's seat in close contact with or close to the vehicle body surface. Additionally, if you want to shrink the packaging behind the driver's seat in close contact with or close to the vehicle body surface, you can use a uniaxially stretched film that can be heat-shrinkable in the vehicle width direction for the area behind the top of the rear glass. .

0010

[Function] According to the heat-shrinkable packaging for automobiles of the present invention, a uniaxially stretched film that can be heat-shrinkable in the vehicle width direction is used at least in the portion that covers the front of the upper end of the windshield. Irrespective of the protrusion or depression in the longitudinal direction, the package covering the area in front of the upper end of the windshield can be shrunk in the vehicle width direction. In other words, generally, the vehicle body surface in the vehicle width direction is substantially smooth with few protrusions or depressions, so the package that is coated in front of the upper end of the windshield will not stick tightly to the vehicle body surface. They will contract in close proximity.

[0011]

[Example] A uniaxially stretched film was prepared which had a tensile elongation in the longitudinal direction of 200% or more and a transparency (haze) of 5% or less when subjected to 30% heat shrinkage. Then, using this flexible and transparent uniaxially stretched film that can be contracted only in the longitudinal direction,
As shown in FIG. 1, a heat-shrinkable package 1 for an automobile was created to match the shape of an automobile 2. However, the films of the ceiling part 10, the side parts 11, and the rear vehicle width part 12 are aligned so that the contraction direction is the vehicle length direction A of the automobile 2, and the films of the front vehicle width part 1
Only in No. 3, the contraction direction was set to be the vehicle width direction B of the automobile 2.

[0012] When the above-mentioned automobile heat-shrinkable package 1 was placed on the automobile 2 and shrink-wrapped using a hand gun that blows out hot air, as shown in FIG. It was possible to package the product in close contact with the vehicle body surface, namely the windshield and bonnet.

[0013] I lifted up this wrapped film, opened the door, got into the driver's seat, closed the door, folded down the film, and drove the car with the film back wrapped, but I could not see clearly in front of me. Ta.

[0014]

[Comparative Example] A uniaxially stretched film similar to that of the above embodiment was used, and as shown in FIG.
A heat-shrinkable package 3 for an automobile was created, which was aligned in the longitudinal direction A of the vehicle.

When the above-mentioned automobile heat-shrinkable package 3 was placed over the automobile 2 and shrink-wrapped using a hand gun that blows out hot air, the film on the front vehicle width portion 33 was pulled, and the driver's seat was pulled as shown in FIG. A film surface different from the tilt angle of the front windshield was formed.

After lifting up the packaged film, opening the door, getting into the driver's seat, closing the door, folding down the film, and trying to drive the car with the package back in its original state, however, the sun's rays Depending on the angle of the vehicle, the driver could see or not see what was ahead, making safe driving impossible.

[0017]

As described above, according to the present invention, the package coated in front of the upper end of the windshield is
Since shrink wrapping can be performed in close contact with or close to the vehicle body surface, the automobile can be safely driven after shrink wrapping.
