Partially transparent bath toys
View Patent ↗A hollow thermoplastic toy for use in a child's bath, having a vent hole, a transparent region and an opaque region, is manufactured by blow-molding a parison which features a region of transparent thermoplastic and a region of opaque thermoplastic. The transparent region serves to permit visual detection of the growth of mold or mildew within the toy.
1 . A hollow toy having a vent hole and having visibility into an interior of the toy sufficient to permit visual detection of mold and mildew growth, manufactured by process comprising:
(a) extruding a transparent thermoplastic and an opaque thermoplastic to form a parison having a transparent region and an opaque region,
(b) blow-molding the parison within a mold, by blowing air into the parison through a nozzle, so as to form the hollow toy and provide the toy with transparent and opaque regions,
(c) withdrawing the nozzle from the mold after the formed toy has solidified, and
(d) trimming excess thermoplastic so as to form the vent hole;
wherein the toy is capable of floating in a bath, and wherein the vent hole enables the toy to be useful as a squirting toy.
2 . The toy according to claim 1 , wherein the region of the toy that is formed from a transparent thermoplastic accounts for 10-90% of the surface area of the toy.
3 . The toy according to claim 2 , wherein the region of the toy that is formed from a transparent thermoplastic accounts for 30-70% of the surface area of the toy.
4 . The toy according to claim 3 , wherein the region of the toy that is formed from a transparent thermoplastic accounts for 40-60% of the surface area of the toy.
