Abstract
Abstract A childproof safety package including a container having a spring member secured thereto with a cap engaging portion surrounding the discharge opening of the container, the cap engaging portion being yieldable along the container axis. A plurality of container locking elements are located a fixed axial distance from the normal unstressed position of the cap engaging portion such that the cap engaging portion is resiliently yieldable toward the container locking elements from its normal position. A safety cap is mounted on the container having a plurality of cap locking elements engageable with a disengageable from the container locking elements by combined axial and rotative motion of the cap relative to the container, and the cap engaging portion of the spring member engages the inner surface of the end wall of the cap when the locking elements are engaged to bias the cap against axial movement from locked engagement with the container.
