The invention provides a de-oxidant seal bottle. When a bottle cap is snapped at a bottle opening, a downward drawing force can be formed to extrude and attached the edge of a seal pad on the bottle cap to the bottle opening of a bottle body, and the upper end of a seal strut of the seal pad is promoted to be embedded in a vertical extension section of a second ventilation through hole in the capsule wall of the top of the seal pad to seal the second ventilation through hole. A snapping ring is withdrawn from a protrusion portion of the bottle body and is held to lift a stretching portion of the bottle cap upwards to enable the bottle cap to rotate upwards around the connection mounting portion, the upper end of the seal strut can be pulled out of the second ventilation through hole, and accordingly, the seal effect is lost, the acting force for 'absorbing' the bottle cap due to the atmospheric pressure difference in and out of the bottle disappears along with the losing of the sealing effect, and the bottle cap of the seal bottle can be opened easily. By means of the seal bottle, the problems that frosted-opening glass bottles, wood-cork glass bottles and the like are inconvenient to save and use when being used for storing de-oxidants in the prior art are well solved.
