Abstract

Hermetic closing cap for deposits, which is essentially characterized by being formed by two circular bodies, which face each other, of which one of them, which is hollow and of frusto-conical configuration, acts as a support, presenting the upper base with the open edge covered with an elastic lining and the lower base with a mesh disk, whose contour is folded on the frusto-conical surface, where a groove parallel to said lower base facilitates the accommodation of a clamp that fixes said mesh disk a filter, while the second circular body is constituted by a cover, slightly convex, with the flat edge of equal diameter to the corresponding to the aforementioned support and also covered with an elastic lining, fixing in its central point an appropriate clamp to give and locating the rod of the closing device, which, at both ends, is housed in two hooking heads which and, in turn, they are screwed on the surface of the tank to be closed, which must be at a lower level than the situation of the clamp, in order to produce the bending of the said rod, which gives rise to compression of the cover against the support sealing it tightly.
