ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a hollow resin container, such as a fuel tank or the like, which is provided in an automobile.
2. Description of the Related Art
FIG. 6
shows an example of a hollow resin container, such as a fuel tank, which is provided in an automobile. In this fuel tank
100
, a gas barrier sheet
104
serving as a sheet material for preventing permeation of gasoline is provided on a matrix resin layer
102
at the inner side of the tank
100
.
However, in the conventional fuel tank
100
(hollow resin container), the inner surface of a part attachment portion
108
, to which an external part such as an inlet hose
106
or the like can be attached, is not covered with the gas barrier sheet
104
from the viewpoint of improving moldability. In other words, cut end portions
104
A of the gas barrier sheet
104
are provided at a base end portion
108
A of the part attachment portion
108
which is formed integrally with the resin layer
102
. Usually, a seal portion
110
for preventing leakage of liquid is formed at the part attachment portion
108
which connects the fuel tank
100
(hollow resin container) and the external part such as the inlet hose
106
or the like. However, in this conventional example, a region
112
, at which the gas barrier sheet
104
does not exist, is formed between the seal portion
110
and the base end portion
108
A of the part attachment portion
108
. Accordingly, sealability in this region is low.
SUMMARY OF THE INVENTION
With the aforementioned in view, an object of the present invention is to obtain a hollow resin container which can improve sealability at a part attachment portion, to which a part which is outside of the container can be attached.
The present invention is a hollow resin container which is formed from a resin, the inner surface of the hollow resin container being covered by a sheet material, and the hollow resin container having a part attachment portion to which an external part can be attached, wherein: the sheet material extends to a region further toward an opening end side of the part attachment portion than a seal portion, which is formed by the part attachment portion and the external part attached to the part attachment portion.
In the present invention, the inner surface of the part attachment portion of the hollow resin container is covered by the sheet material to a region further toward an opening end side of the part attachment portion than a seal portion, which is formed by the part attachment portion and the external part attached to the part attachment portion. Therefore, sealability at the part attachment portion is excellent.
