Abstract: A container for a viscous liquid, gel or paste-like substances has a closure integrated into its cap. The closure operates via a partial turn from open to closed, without separating into multiple parts. Even when open, one-way valves prevent the container contents from escaping until the flexible body of the container is squeezed to expel the contents. An outer surface of the closure is provided with brush bristles, and expelled container contents emerge among the bristles. The brush may be used to apply the expelled contents onto a surface. A separate cap may be provided to cover the bristles when the container is not in use. The bottle and a portion of the closure may be formed integrally. The bottle may have an arbitrary shape, such as a cartoon animal, and/or an opening to accept a carabiner for hanging the container.
