Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a portable case equipped with a hanging belt, such as a portable lunch box or a portable liquid container.

(Prior Art) As a portable case equipped with a hanging belt, as shown in Fig. 4, a belt end attachment shaft c is provided on the outer surface of the case body b, and the end of the hanging belt a is hung thereon. In addition, it is known that the device is attached by folding it in two. Then, there is a belt end mounting shaft c provided on the outer surface of the case body b, a holding portion d provided above the belt end mounting shaft c for inserting and holding the hanging belt, and a connection between the belt end mounting shaft c and the holding portion d. A frictional force is applied to the end part f of the hanging belt a by the protrusion e that bends the hanging belt a folded in half, and the case body b bends the hanging belt a.
It is suspended by a rope.

(Problems to be Solved by the Invention) In the above-mentioned conventional example, since the belt end attachment shaft c protrudes outward, there is a problem that the belt end attachment shaft c hits the body and gets in the way when carried in a hanging manner.

Also, the belt end mounting shaft c is located at a position protruding from the outer surface of the case body b, and the end f of the hanging belt a is
is laterally away from the outer surface of the case body b, so the hanging belt a attached to the belt end attachment shafts c on both sides of the case body b is separated from the outer surface of the case body b. There is a problem in that the carrying position becomes unstable as the user has to hold the position b.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a pair of left and right belt end attachment shafts at the bottom corners of the case body, respectively, inward from the outer surface and outer bottom surface of the case body. Both ends of the hanging belt are attached to these belt end attachment shafts, and the parts above the both ends of the hanging belt are aligned with the outer surface of the case body. .

(Function) According to the present invention, since the belt end mounting shaft is located inside the outer surface and the outer bottom surface of the case body, the belt end mounting shaft does not protrude outward from the case body. It does not get in the way and does not cause any trouble when it is placed.

In addition, when hanging, the ends of the hanging belt are pulled inward from the outer surface of the case body by the belt end attachment shaft located at the above position, so that the upper part of the hanging belt is pulled upward from both ends of the hanging belt. Since the portion presses against the outer surface of the case body from both sides, the carrying posture of the case body can be stabilized.
