A cosmetic packaging device with aligning cap includes connection structures and/or a collar that facilitate easy alignment of the cap/applicator to the cosmetics packaging in order to achieve a desirable appearance in an easy manner to the user. Ramped edges on one or both of the collar on a bottle and/or a connecting structure of an applicator are designed to guide a tab into a slot as the applicator and cap are replaced on the cosmetics packaging, which may contain a cosmetic product such as a mascara, lip gloss or various other products.
