The invention relates to an improved glue bottle. The improved glue bottle is characterized by comprising a coating end, an annular port, a bottle body and a bottle cap, wherein the coating end is connected to the annular port, and the annular port is connected to the bottle body; the end surface of the coating end is a protruded hollowed-out arc-shaped surface and is wrapped with a closely wovengauze; a water absorbing resin which is in a shape of a cylinder body is arranged on the bottom surface of the inner side of the bottle cap; after the water absorbing resin absorbs full water, the bottom area of the cylinder body is equal to that of the bottle cap; the net-shaped gauze is fixedly connected to the inner side surface of the bottle cap, and the water absorbing resin is positioned ina space between the net-shaped gauze and the bottom part of the bottle cap; and the bottle cap is connected to the annular port in a clamping manner. The improved glue bottle is low in cost, and highin efficiency; the technical problem that the coating end of the glue bottle is blocked by solidified in case that the opened glue is not used for a long time can be solved; and glue without being used for a long time can smoothly flow from the coating end to an object to be coated.
