Abstract
A cosmetic applicator using a thermoplastic attachment and method of manufacture is provided. The cosmetic applicator comprises an elongate wand having a first end, the wand comprising a polymeric material, a tip having an interior cavity with an open-end mouth, the first end of the wand positioned in the interior cavity of the tip, the tip comprising resilient polymeric foam having a plurality of cells and sized to substantially cover the end of the wand, and a thermoplastic material adhered to the first end of the wand and melted into the cells of the foam in the interior cavity of the tip for securing the tip to the first end of the wand.
Claims20
A cosmetic applicator, comprising:
- an elongate wand having a first end, said wand comprising a polymeric material;
- a tip having an interior cavity with an open-end mouth, the first end of the wand positioned in the interior cavity of the tip, the tip comprising resilient polymeric foam having a plurality of cells and sized to substantially cover the end of the wand;
- and
- a thermoplastic material adhered to the first end of said wand and melted into the cells of the foam in the interior cavity of the tip for securing said tip to the first end of said wand.
A cosmetic applicator comprising:
- an applicator tip comprising resilient polymeric foam having a plurality of cells and having a melting temperature higher than about 250 degrees Fahrenheit, the applicator tip having an cavity;
- an elongated wand having a melting temperature of about 180 degrees Fahrenheit having a first end, the first end of the wand positioned inside the cavity of the applicator pad;
- and
- a thermoplastic material adhered to said first end of the wand and melted into the cells of foam inside the cavity of the applicator pad for attaching the applicator pad to the first end of the wand, said thermoplastic material having a melting temperature higher than about 140 degrees Fahrenheit and lower than about 180 degrees Fahrenheit.
A method for making a cosmetic applicator comprising the steps of:
- forming a plurality of applicator tips from polymeric foam having a plurality of cells;
- forming a plurality of elongated wands each having a first end;
- forming a cavity in each of the applicator tips;
- applying a thermoplastic material onto one of the first ends of the wands;
- inserting the first end of the wand having applied thermoplastic into one of the cavities of the applicator tips;
- and
- heating the thermoplastic, the applicator tip and the first end to a temperature above a melting point of the thermoplastic to flow the thermoplastic into the foam cells and retain the tip on the handle.
