2. Description of the Related Art Conventionally, this type of container has been disclosed in Japanese Utility Model Publication No. 4-355.
As disclosed in Japanese Patent Publication No. 76-76 and shown in FIG. 11, a paper tube P having an inner surface coated with an aluminum foil or a resin film F is used to form a container main body A for accommodating a sealing main agent therein and the container main body. Reinforcing metal fitting S on the open end of A
Is fixed by winding in a ring shape, and while the strength of the container body A made of paper tube is compensated by the reinforcing metal fittings S, the container body A, which is a main component, is made of paper to facilitate incineration and waste pollution. The problem of is suppressed.

On the open side of the container body A, a lid B provided with a recess D for accommodating a hardening agent W in a bag to be mixed with a main sealing agent is detachably attached. Also, the container body A
At two positions on the circumference of the container, inverted U-shaped handle attachment fittings M are laid on the inner and outer surfaces of the container main body A so as to groin, and the upper folded portion is provided with the reinforcing attachment S and the lower free end portion is provided. Each is fixed by a rivet L, and an end of a metal C-shaped handle H is attached to the outer bulging portion E.

[0004]

However, in the above, the disposal is much easier than the case where the container body is formed of a tin can, an aluminum can, etc. There is a problem that the metal fittings S and the like remain as waste.

Further, since a metal C-shaped handle H is used and the handle H is disposed in a hanging state on the container body A, the protrusion of the handle H causes a large amount of dust to be brought into the incinerator. Disposal is also disadvantageous from the point of view, and at the time of use, when the sealing main agent and the curing agent are mixed by a rotary stirrer, the handle H hangs down on the outer surface of the container main body A, so the container main body A is supported by the stirrer. There are also problems that are difficult to maintain.

An object of the present invention is to provide a container for a two-part composition which can more easily be discarded by combustion while ensuring the strength of the container body, and another object is to provide the container. Thus, it is another object of the present invention to provide a container for a two-part composition, which can be disposed of more easily by improving the handle portion and can improve workability during stirring.
