all in accordance with an embodiment of the invention.
In the following detailed description, reference is made to the accompanying drawings which form a part thereof. In the drawings, similar symbols typically identify similar components unless context indicates otherwise. The illustrative embodiments described in the detailed description, drawings and claims are not meant to be limiting. Other embodiments may be utilized and other changes may be made without departing from the spirit or scope of the subject matter presented herein. It will be readily understood that the aspects of the present disclosure as generally described herein and as illustrated in the accompanying figures can be arranged, substituted, combined, separated and/or designed in a wide variety of different configurations all of which are explicitly contemplated herein.
At 102, a material 10 and a fragrance 20 may be placed within mixing chamber 30. Material 10 may be a plastic material. Material 10 may include one or more of ethylene vinyl acetate (EVA), low-density polyethylene (LDPE), high-density polyethylene (HDPE), polypropylene (PP), polyvinyl chloride (PVC), thermoplastic elastomer (TPE), polyethylene terephthalate (PET), styrene acrylonitrile (SAN), acrylonitrile butadiene styrene (ABS), polycarbonate PC, cellulosics, and/or cellulose acetate. Material 10 may further include one or more filler materials. Filler materials included in material 10 may also act as a stabilizer. Filler materials included in material 10 may include one or more of vermiculite, calcium carbonate, sodium bicarbonate, and boric acid.
Fragrance 20 may include lice repelling oils. Fragrance 20 may include natural oils. Fragrance 20 may include one or more of heliotropin (also known as piperonal), lemon oil, rosemary oil, eucalyptus oil, tea tree oil, carrot seed oil, anise oil, mint oil, carambola oil, citronella oil, and camphor oil.
As shown in
At 104 mixture 40 may be feed into hopper 60 of injection molding machine 110. Gravity may guide mixture 40 from hopper 60 to barrel 70. Mixture 40 may be moved mechanically through barrel 70 to nozzle 80 and injected into mold 90 by screw-type plunger 75. Mold 90 may be at a lower temperature than mixture 40 and mixture 40 may solidify as mixture 40 fills mold 90.
At 106 solidified mixture 40 may be removed from mold 90 as molded unit 120. Molded unit 120 may be a plastic material infused with fragrance 20. Molded unit 120 may include one to forty mass percent fragrance 20.
Processing may begin at block S2, “Place a plastic material into a mixing chamber.” At block S2, a plastic material may be placed into a mixing chamber. The plastic material may include one or more of ethylene vinyl acetate (EVA), low-density polyethylene (LDPE), high-density polyethylene (HDPE), polypropylene (PP), polyvinyl chloride (PVC), thermoplastic elastomer (TPE), polyethylene terephthalate (PET), styrene acrylonitrile (SAN), acrylonitrile butadiene styrene (ABS), polycarbonate PC, cellulosics, and/or cellulose acetate. The plastic material may further include one or more filler materials. The filler materials may also act as a stabilizer. The filler materials may include one or more of vermiculite, calcium carbonate, sodium bicarbonate, and boric acid.
Processing may continue from block S2 to block S4, “Place a lice repellent oil into the mixing chamber.” At block S4, a lice repellent oil may be placed into the mixing chamber. The lice repellent oil may include natural oils. The lice repellent oil may include one or more of heliotropin (also known as piperonal), lemon oil, rosemary oil, eucalyptus oil, tea tree oil, carrot seed oil, anise oil, mint oil, carambola oil, citronella oil, and camphor oil.
Processing may continue from block S4 to block S6, “Mix the plastic material and the lice repellent oil in the mixing chamber to produce an infused plastic material.” At block S6, the plastic material and the lice repellent oil may be mixed in the mixing chamber to produce an oil infused plastic material. Mixing may be performed mechanically, such as by a stirrer. The stirrer may be operated at a speed of 10 rotations per minute to 100 rotations per minute. A heater may be in thermal communication with the mixing chamber so as to provide heat to the mixing chamber during mixing of the plastic material and the lice repellent oil. The heater may supply heat sufficient to melt the plastic material. The heater may provide heat to the mixing chamber to raise a temperature of the mixing chamber to a range from 15 degrees centigrade to 60 degrees centigrade. The mixing and heating may be performed for a time period of 2 minutes to a time period of 2880 minutes. The mixing of the plastic material and the lice repellent oil may produce an oil infused plastic material. The oil infused plastic material may include the plastic material infused with the lice repellent oil. The oil infused plastic material may include one to forty mass percent of the lice repellent oil.
Processing may continue from block S6 to block S8, “Feed the infused plastic material into a hopper of an injection molding machine.” At block S8, the infused plastic material may be feed into a hopper of an injection molding machine. Gravity may guide the infused plastic material from the hopper to a barrel of the injection molding machine.
Processing may continue from block S8 to block S10, “Form the material for repelling lice by injection molding of the infused plastic material.” At block S10, the infused plastic material may be injection molded to form the material for repelling lice. The infused plastic material may be may be moved mechanically through the barrel of the injection molding machine to a nozzle and injected into a mold by a screw-type plunger. The mold may be at a lower temperature than the infused plastic material, and the infused plastic material may solidify as the infused plastic material fills the mold, and form the material for repelling lice.
Among other potential benefits, an embodiment of the present application may be a hair accessory which may be worn in a user's hair to repel lice. An embodiment of the present application may provide a natural louse repellent in a fashionable hair accessory. An embodiment of the present application may provide a user with a convenient lice repellent accessory that may repel lice from head and hair of a user.
While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art.
