The present invention features a safety seal for a liquid spray dispensing assembly consisting of a sprayer mechanism and a container. A typical spray dispensing assembly has a container with a threaded cylindrical neck defining a container opening, and a sprayer mechanism with a pump mounted onto a threaded cap and a dip tube which extends into the container when the cap is threadedly secured to the neck of the container. Liquid is drawn from the container through the dip tube by operating the pump. The safety seal has a flange portion, a first sealing portion and a second sealing portion. The flange portion is insertable into the cap for contact with the rim of the neck when the cap is secured to the exterior surface of the neck. The flange retains the seal within the container opening. The first sealing portion extends from the flange and provides a frictional circumferential seal with the interior surface of the neck adjacent the neck rim. The second sealing portion is disposed across the container opening when the safety seal is placed into the opening, and provides an aperture for sealing engagement with the dip tube. The safety seal is resistant to the effects of vibration or other factors that would cause a backing-off or negative rotation of the cap portion of the sprayer mechanism with respect to the neck portion of the container to which it is secured.
