This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This summary is not intended to identify key features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
The foregoing aspects and many of the attendant advantages of this invention will become more readily appreciated as the same become better understood by reference to the following detailed description, when taken in conjunction with the accompanying drawings.
Application of cosmetic compositions, such as lip gloss, lip color, creams, gels, ointments, foundations, concealers, sunscreen, acne treatments, and others, usually involves an individual controlling the dosage of the composition being applied to the body. This is often difficult, in particular when the composition is thick or viscous. In these and other situations, excess composition can be inadvertently applied to the body, resulting in undesired product application or prolonged efforts to apply a desired amount of the composition to the body. In addition to this being a frustrating experience for a consumer, it is also wasteful as excess composition is generally discarded and not used. Accordingly, there is a need for applicators for applying cosmetic compositions that facilitate greater control over and definition of dosages of compositions being applied. The present disclosure addresses this and other long-felt and unmet needs in the art.
In an aspect, the disclosure provides an applicator for application of a defined dosage of a cosmetic composition and avoidance of unnecessary or excess amounts of the composition, reducing waste and improving the quality and reproducibility of the product application process. Example applicators are shown at
In embodiments, the aperture 9 is disposed through a distal portion of the head 2. The force for slidably moving the head 2 along the shaft 3 for dispensation of the composition can be applied by contacting a skin surface or other portion of a body of an individual to the distal portion of the head 2, such that with discharge of the defined dosage of the cosmetic composition from the aperture 9, the cosmetic composition contacts the skin surface or other portion of the body. As such, the head 2 is contactable to the surface (e.g., skin surface), such that the force applied to the shaft 3, in a direction of the surface, overcomes the bias member and slidably positions the head 2 toward the proximal position relative to the piston and concomitantly discharges the defined dosage of the cosmetic composition from the volume of the interior to the exterior of the head 2 through the aperture 9 by the piston. The distal portion of the head 2 can comprise the aperture 9 therethrough, such that as the distal portion of the head 2 contacts the portion of the body of the individual, the cosmetic composition can directly contact the skin surface after exiting the aperture 9. In this manner, the composition is more efficiently applied to the skin surface or other body portion, and there is reduced waste that is produced by the application process.
In embodiments, the distal portion of the head 2 is angled relative to an axis of the shaft 3 of the applicator 7. The distal portion of the head 2 can include a surface through which the aperture 9 passes, and the surface can be angled relative to the axis of the shaft 3 according to an angle that is not 90 degrees. The angle of the surface of the distal portion of the head 2 can facilitate ergonomic application of the composition during use, such that an individual grasping the applicator 7 does not necessarily need to position the shaft 3 about 90 degrees with respect to the portion of the body to which the composition is being applied. In this manner the applicator 7 is able to be more comfortably used for longer periods.
In embodiments, the bias member 10 is unitary with the head 2. As shown in the figures, including at least at
In embodiments, the bias member 10 is a stem that extends from a rim of the aperture 9 into the volume of the interior of the head 2 and contacts the piston 18 of the shaft 3. As shown at

In embodiments, the shaft 3 comprises a handle attachment 17 at a distal portion thereof for attachment of the applicator 7 to a handle 4, as shown by way of example at
In embodiments, the volume of the interior of the head 2 corresponds with, or defines, the defined dosage based on a size of the piston 18 of the shaft 3 and a distance traveled by the piston 18 as the head 2 transitions from the distal position to the proximal position relative to the piston 18, as shown by way of example at

Upper ridges 12 of the shaft 3 abut against inner ridges 13 of the head 2 when the bias member 10 is in the expanded configuration (e.g.,
