Abstract
Abstract An inhaler device has a vessel containing the substance to be inhaled and a lid helping to vaporize the substance to be inhaled. The lid includes a generally central opening and several openings positioned in a ring around the central opening. The central opening is formed such that it extends deeper in the vessel than the several openings that are arranged in a ring. The cross-sectional area of the central opening are generally equal to the sum of the cross-sectional areas of the several openings for enabling a sufficient quantity air to be drawn into the several openings to vaporize the substance to be inhaled.
