PURPOSE:To improve the safety of a push-up type hot water containing coffee boiler and to prevent staining of the boiler by preventing the overturn of a glass vessel thereof. CONSTITUTION:On the front part of a trunk portion 20a in the upper body 20 having an inverted L shape, a projection 20b is provided. In addition, the curvature of the lower surface of the projection 20b is rendered approximately equal to the curvature of the shoulder part of the glass vessel 10. The projection 20b and the shoulder part of the glass vessel are designed so that the two are allowed to closely adhere to each other. The boiler is so constituted that even an external force carelessly applied to the glass vessel 10 cannot overturn the vessel. By the construction, the boiler can be cleanly and safely used. |
