ABSTRACT:
BACKGROUND OF THE INVENTION
The invention relates to a cosmetic dispenser and, more particularly, to a mascara applicator having a simple and cost-effective structure which is nevertheless simple and easy to use and therefore consumer-friendly.
Cosmetic application arts are extremely well known, and applicators or dispensers for applying cosmetics such as facial mascara are numerous. Many of these devices are complex and therefore expensive to manufacture. One trend has been toward more simple and less expensive dispensers, particularly toward dispensers which can be used as product samplers.
One example of an attempt to provide a simple mascara dispenser is illustrated in U.S. Pat. No. 4,411,282 to Wavering. In this device, a simple bottle is provided having a cap and an applicator attached to the cap. In this device, the cap and applicator structure requires two separate injection-molded or otherwise formed parts and the bottle is a third part. In addition, the structure does not provide for ready alignment of threads between the cap and the container and therefore can easily become jammed when the cap is being placed upon the container. Further, the applicator structure itself requires a specific mechanical structure which adds to the cost of the device.
Despite the numerous disclosures in this art, the need remains for a simple, reliable and consumer-friendly cosmetic dispenser.
It is therefore the primary object of the present invention to provide a cosmetic dispenser which is inexpensive to manufacture.
It is a further object of the present invention to provide a cosmetic dispenser which is easy and reliable to use, and therefore consumer-friendly.
It is a still further object of the present invention to provide a cosmetic dispenser which is sufficiently simple and inexpensive to manufacture that it can readily be used as a sampler.
Other objects and advantages of the present invention will appear hereinbelow.
SUMMARY OF THE INVENTION
In accordance with the present invention, the foregoing objects and advantages have been readily attained.
According to the invention, a cosmetic dispenser is provided which comprises: an applicator having an applicator portion and a cap portion, said cap portion having an inwardly facing screw thread; a container member having a body portion defining a product reservoir and having a neck portion extending from said body portion to receive said applicator, said neck portion having an outwardly facing screw thread for threadedly engaging said inwardly facing screw thread; and a smooth-walled thread guide portion extending from one screw thread of said inwardly facing screw thread and said outwardly facing screw thread toward an opposing screw thread of said inwardly facing screw thread and said outwardly facing screw thread, said thread guide portion being sized to slidingly engage said opposing screw thread so as to guide said opposing screw thread to said one screw thread in proper alignment for threaded engagement.
The cap structure is also designed to allow for a single-piece manufacture for receiving a brush or applicator member while still allowing stable resting of the dispenser on its cap.
