The present invention relates to a size changeable funnel of which side (120) is made of elastic material, and which has a built-in armature capable of changing forms inside an upper part (110) and a lower part (130) so as to freely change the curvature. The side (120) of the funnel is made of elastic material, and an armature, capable of changing forms, is built in the upper (110) and the lower (130) parts, so that the funnel can be suitably manufactured to match the size of an opening of a bottle. The funnel can be used to prevent contents from flowing down, along a side of and to the back of a vessel, when transferring the contents in a large vessel to another vessel. |
