Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a suspension string attachment structure for a container such as a thermos flask, in which a suspension cord is detachably attached to a container such as a portable thermos flask.

[Prior Art] Portable thermos flasks and the like are detachably attached to a hanging string for convenient portability. By this,
The hanging string does not get in the way when washing or drying the thermos. This attachment structure for the removably provided suspension string includes an attached portion provided on the outer periphery of the thermos flask, and a stopper connected to the suspension string removably connected to this attached portion. An example of this is the 59th U.S.
-103640, the attachment part is formed by a notch formed in a band-like member attached to a thermos flask, the stopper is formed by a fishing metal fitting that can move back and forth elastically, and the convex part of this fishing fitting is A device is disclosed that is rotatably fitted into a fitting recess formed in a notch.

Also, as a conventional product of this kind,
Publication No. 49644 discloses that a ring having insertion holes for a hanging string and a handle at symmetrical positions is fitted at two locations on the outer periphery of a container body, and the insertion holes are provided at the same positions on both rings. A suspension string attachment structure has been proposed in which the two sides are positioned on the same axis of the outer peripheral surface of the container body, the suspension strings are inserted into the insertion holes, and the handles are inserted and supported.

[Problem to be solved by the invention] By the way, conventional methods for attaching hanging strings include a vertical hanging method in which the hanging strings are connected to both sides of the upper part of the container, and a horizontal hanging method in which the hanging strings are connected to the upper and lower parts of the container, respectively. This is known as the hanging method.

However, when the above-mentioned fishing hardware is rotatably connected to the notch and is hung vertically and can be hung horizontally, the above-mentioned stopper itself also rotates, making it difficult to hang the hook when lowering the shoulder. There was a problem with stable movement. In other words, not only the suspension string moves, but the stopper itself rotates, so it moves in two stages. Furthermore, in the case of a device in which the insertion direction of the stopper is unidirectional, there is a problem in that it is limited to either a vertical hanging method or a horizontal hanging method, which limits the range of use.

In addition, in the above-mentioned device in which the suspension string and the handle are selectively provided, the means for connecting the suspension string is to pass the end of the suspension string through the insertion hole to form a ring, and connect the ends with one touch. There was a problem that the string could not be attached or detached.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide a structure for attaching a hanging string to a container such as a thermos flask, in which the hanging condition is stable and the hanging string can be easily attached and detached.
