DESCRIPTION:
BRIEF SUMMARY
This invention relates to an artificial nail tip for enhancing the appearance of a natural fingernail.
Pre-formed artificial nail tips are well known and are usually designed to be placed on top of a natural fingernail of a user with the artificial nail tip extending beyond the end of the natural nail and being secured in position by suitable adhesive. In order to facilitate fixture, the trailing end of the artificial nail tip is either made slightly thinner than the leading end of the nail tip or the nail tip is provided with a shoulder on the inner surface of the artificial nail tip which abuts up against the end of the natural fingernail.
In the prior arrangement disclosed, once secured in position, the junction between the artificial nail tip and the natural fingernail is coated with filler so as to provide a smooth appearance.
A problem with existing artificial nail tips, as opposed to artificial fingernails is that they are more susceptible to damage and to becoming detached because of the relatively small area of adhesive securement to the natural fingernail. With artificial fingernails, the artificial fingernail is secured to substantially the whole of the top of the natural nail by adhesive and therefore this has not been a real problem. However, in respect of artificial fingernails, it has been proposed to provide the underside of the projecting end of the artificial fingernail with a pocket which encloses the projecting tip of the natural nail so as to help prevent displacement. Such an artificial fingernail is disclosed in U.K. Patent Specification No. 662080.
However, in practice, the proposal of a securing pocket was never adopted because the trailing end of an artificial fingernail is adapted to fit against, or just under, the user's cuticle. As users have different sizes of nails, a pocket would always be in the wrong position for ensuring that the trailing end of the artificial fingernail was properly positioned. The proposal in U.K. Specification No. 662080 does attempt to deal with this problem by providing transverse weakening lines across the pocket so that portions of the pocket could be detached, but this did not prove acceptable and artificial fingernails are formed without any such arrangement. Moreover, the proposal did not have regard to moulding practicalities and, in practice, an artificial finger nail having a pocket of this type would be extremely difficult to injection mould. Accordingly, with these disadvantages, the industry, having considered this type of arrangement as impractical for artificial fingernails, has been directed away from this type of security fixture and towards increasing adhesion of the applied artificial fingernail tip as disclosed in, for example, U.S. Pat. No. 4,596,260.
An object of the present invention is to provide an improved artificial nail tip which helps prevent detachment, for example, when the point of the artificial nail tip is caught on an article.
According to the present invention, there is provided an artificial nail tip for bonding to a user's natural fingernail so as to extend beyond the end thereof whilst leaving a portion of the upper surface of the natural fingernail exposed, the nail tip comprising a body having underside and outer surfaces extending between a leading end and a trailing end and a shoulder on the body defining a thinner body portion adjacent the trailing end of the body and which, in use, abuts the free end of a user's natural fingernail, characterized in that the shoulder is on the underside surface of the body, and a projection extends rearwardly from a central position on the shoulder whereby, in use, the projection may be engaged under a user's natural fingernail to resist detachment.
The body of the artificial nail tip is suitably arched to meet the normal curvature of a natural fingernail. Preferably, the projection extends laterally a distance substantially less than the lateral extension of the artificial nail tip to facilitate injection molding.
The invention also includes an artificial nail tip comprising
