Embodiment Construction

[0019] According to the drawing, a preferred embodiment of the pre-glued nail decoration elongated accessory according to the invention is shown. Attachment 10 generally includes an elongated cover layer 11 and a pressure sensitive adhesive layer 12 secured to the bottom surface of the cover layer.

[0020] Covering layer 11 has a top surface 13 , a bottom surface 14 , a first (or proximal) end 15 , and a second (distal) end 16 . The first end 15 should at least approximate the shape and size of the end of a user's fingernail in terms of shape and size. In the case of nail tip 17, such as figure 1 As shown, the first end 15 should approximate the shape and size of a user's fingernail in shape and size. In the case of the nail cover 18, as shown in FIG. 2, the first end 15 is about the shape and size of the entire natural nail in shape and size.

[0021] Covering layer 11 is generally of uniform thickness, but may be reduced in thickness at the first (ie, tapered) end to adh...

Abstract

An ornamental accessory for a fingernail comprises an overlay having a reusable pressure-sensitive adhesive layer pre-applied to a bottom surface thereof for application and bonding to the wearer's natural nail, and a method of making the same. The adhesive formulation is a copolymer of acrylic ester and vinyl acetate formed from an aqueous acrylic copolymer emulsion. The bottom surface of the overlay to which the adhesive is applied is textured to enhance adhesion of the adhesive layer. A method for forming a pre-glued ornamental fingernail accessory includes the steps of forming an overlay having the shape and size of a natural fingernail and applying an aqueous copolymer emulsion, as described above, to a bottom surface of the overlay. The emulsion is allowed to cure whereby a substantial portion of the water in the emulsion is evaporated to form a reusable pressure-sensitive adhesive layer fixed to the overlay. The pressure-sensitive adhesive layer is reactivated by adding an aqueous solution to the dried aqueous copolymer emulsion.

Description

[0001] This application is a divisional application of the No. 01115901.4 Chinese patent application with the filing date of April 30, 2001, entitled "Pre-glue Nail Decoration Accessory and Manufacturing Method thereof". technical field [0002] The invention relates to a nail decoration accessory technology, in particular to a false nail technology with a pre-applied fixed adhesive layer. Background technique [0003] Nail decoration accessories for decorative hands are well known and are made of film molded plastic to form the nail shape. Typically, the user applies a quantity of liquid adhesive to the appendage and / or the natural nail, and then adheres the appendage to the nail. Typically, the user must wipe or remove excess adhesive and then wait a certain amount of time until the adhesive dries to ensure that the attachment is secured to the nail. When it is time to remove the attachment, the user should soak the attached nail in a solvent for some time to dissolve the...
