The present invention relates to a tube cover for a tube which can prevent the friction between the lid part and the top plate lid, and more specifically, the lid part 23 is formed by a slope on which the body is placed, A lower tube envelope 20 which surrounds the lower tubular body 2 and has a handle portion 25 on both outer sides so as to be able to hold the tubular tube in the mouth； An upper plate envelope (30) surrounding the upper plate (3) covering the lower tubular body (2)； The lower tube envelope 20 and the upper plate envelope 30 are bundled and fixed to each other so that the lower tubular envelope 20 and the upper plate envelope 30 are completely surrounded and bound by the handle portion 25, A strap 40； A lid 50 covering the entire lower tube envelope 20 and the upper plate envelope 30； A plurality of first insertion grooves 31 are formed on the upper side of the upper plate cover 30 so as to be spaced apart from each other by a predetermined distance, Each of the second insertion grooves 51 is formed at a position corresponding to the first insertion groove 31 and one side is inserted into the first insertion groove 31 and the other side is inserted into the second insertion groove 51 When the lower tube envelope 20 and the upper plate envelope 30 are covered with the lid portion 50, the lower inner side of the lid portion 50 is connected to the upper side So that friction between the lid part 50 and the upper plate lid 30 can be prevented by the buffering force of the elastic member 50 from shaking when the lid is moved, When the main purpose of the tube cover is to be maintained and the cover of the tube is covered with the cover, It is possible to prevent loosening of the fastener string to prevent the entire loosening of the cover and to prevent the friction between the upper plate wrapper and the lid part, It is possible to prevent damage to the lid part, which is a useful device for securing ease of storage and handling. 본 고안은 결관끈의 고정력과 덮개부와 상부
