    Abstract: In a first aspect, a process for forming deodorant or antiperspirant sticks by continuously forming a mobile composition for dispensing into containers or molds at a rate matched with the rate at which it is dispensed, and in other aspects a process in which a mobile deodorant or antiperspirant composition is dispensed by injection molding, i.e. a process in which the deodorant or antiperspirant composition is dispensed under pressure. The composition at the time of injection moulding is preferably either in the vicinity of its regular set temperature, particularly in the range of about 0-3° C. below the regular set temperature and/or partially structured at the time of its delivery it into a container or mold. The deodorant or antiperspirant composition is preferably continuously produced in a screw extruder, especially a twin screw extruder, which is controlled to deliver the composition in a substantially semi-solid state, at a temperature close to its regular set temperature and is injected into the container or barrel at a pressure at the point of injection that is often greater than 15 psi. and in many instances from 200 to 400 psi in the injection head. Apparatus for forming deodorant or antiperspirant sticks by injection molding is also described. The combined process offers benefits for incorporating sensitive ingredients and ameliorating sedimentation of particulates such as particulate antiperspirant actives.

    Abstract: A process for forming a molded article having a multilayer structure which comprises successively injecting melts of at least two materials into the cavity portion of a mold, solidifying a part thereof in the cavity portion to form the multilayer structure, characterized in that as a first step, one of the molten materials is injected into the cavity portion and the portion of the injected molten material contacting with the mold surface is solidified to a predetermined thickness to form a skin layer; as the second step, the next molten materials is fed into the cavity, the unsolidified portion of the molten material previously fed is pushed out of the cavity and a part of the thus fed molten material is cooled and solidified from the surface of the mold to form the next layer; and the procedure of the second step is successively repeated using the remainder of the molten materials alternately, and the molded article produced by the above molding process.

    Abstract: An injection moulding process for moulding a material in a mould having a mould cavity and at least one channel communicating with the mould cavity, each channel entering the mould at a respective mould inlet includes the steps of heating inner surface areas of the mould to a temperature above the heat distortion temperature of the material; supplying the molten material into the mould by way of at least one channel and subjecting the molten material to a propelling force, sufficient to propel it through the channel into the mould; causing the molten material in the mould to solidify; applying periodic forces to the material in the mould at a plurality of spaced-apart regions, first and second of the regions being located either side of molten material in the mould cavity, the periodic force being applied with a difference in phase so as to cause shear of molten material within the mould cavity between the first and second regions; cooling the mould below the heat distortion temperature of the resin while or after applying the periodic force; and then opening the mould, and removing the moulded article.
