Hair comb

A method of manufacture of a hair comb, comprising the steps of:

• manufacturing a utility portion of the comb consisting of only a single row of teeth defining a longitudinal length by injecting only a first polymeric material selected from the group consisting of ethylene-vinyl acetate (EVA), polyurethane (PU) and polyethylene (PE) into a corresponding mould, wherein the first polymeric material and the physical configuration of the utility member are configured such that the formed utility portion has a flexural strength of 31 Mpa ±10% and a hardness of Shore D 55 ±10%;
• and
• manufacturing a splint portion including a first portion that couples to the utility portion along the longitudinal length that provides rigidity to the utility portion and a second portion that extends from the first portion and past the utility portion that forms a handle of the comb for a grip of the user by injecting only a second polymeric material that differs from the first polymetric material selected from the group consisting of general purpose polystyrene polymer (GPPS), high impact polystyrene (HIPS), acrylic, acrylonitrile butadiene (ABS), nylon, polyoxymethylene (POM) and acetate into a mould, wherein the second polymeric material and the physical configuration of the splint portion are configured such that the formed splint portion is stiffer and harder than the utility portion and has a flexural strength of at least 40 Mpa and a hardness of at least Shore D 75.

A hair comb comprising:

• a utility member consisting of only a single row of teeth defining a longitudinal length made of only a first polymeric material for engaging hair and scalp of a user in use, and
• a splint member including a first portion that that is connected to the utility member along the longitudinal length that provides rigidity to the utility member and a second portion that extends from the first portion and past the utility member that forms a handle of the comb for a grip of the user and defines a free end spaced from the utility member, the splint member being made of only a second material for providing rigidity to the utility member that differs from the first polymetric material,
• wherein the first polymeric material is selected from the group consisting of ethylene-vinyl acetate (EVA), polyurethane (PU) and polyethylene (PE), and the second material is selected from the group consisting of general purpose polystyrene polymer (GPPS), high impact polystyrene (HIPS), acrylic, acrylonitrile butadiene (ABS), nylon, polyoxymethylene (POM) and acetate,
• wherein the splint member is stiffer and harder than the utility member;
• wherein the first polymeric material and the physical configuration of the utility member are configured such that the utility member has a flexural strength of 31 Mpa ±10% and a hardness of Shore D 55 ±10%, and the second material and the physical configuration of the splint member are configured such that the splint member has a flexural strength of at least 40 Mpa and a hardness of at least Shore D 75;
• and
• wherein the hair comb further comprises connection means for connecting the utility member and the splint member together, the connection means comprising a socket provided in the splint member for receiving the utility member and configured such that during assembly the utility member is slid in a lateral direction into a groove portion defined by the socket and after assembly the utility member is prevented from disengagement from the splint member in a direction perpendicular to the lateral direction.
