Abstract
A dispenser adapted for use in personal application of viscous liquid. The dispenser includes a hollow container for the liquid and valve structure on the container. The valve is automatically shiftable by actuation of an exterior portion thereof to bias a spring structure and permit flow of the viscous liquid to the person. The spring structure is designed so that a substantially uniform opening is provided to facilitate uniform dispensing of viscous liquid such as a lotion. For this purpose, the spring structure includes a plurality of spaced spring stems which act in concert to submit uniformly to pressure in opening of the valve and to substantially uniformly close the valve when the pressure is released. In another form, the dispenser is designed for application of flavoring to a product such as a cigarette and the valve actuator is positioned in relation to a guide so that a product end can be guided into engagement with the actuator to open the valve and permit flavoring contained within the dispenser container to be applied to the product.
