Methods are provided for manufacturing an antiperspirant or deodorant product within a container, the product having an application surface that includes first and second portions having different compositions. The methods generally include (a) delivering to an open end of the container, through a first delivery nozzle, a first composition that will form the first portion, and, through a separate second delivery nozzle, a second composition that will form the second portion, the first and second compositions being in molten form during delivery, (b) providing a barrier between the first and second compositions to prevent intermingling thereof, (c) allowing the first and second compositions to solidify to form the product; and (d) removing the barrier.

The filter element as in claim 8, further including an annular wall supported centrally in said filter media, said annular wall supporting the first annular threaded portion.10. The filter element as in claim 9, wherein said annular wall is fixed to said first end cap.11. The filter element as in claim 10, wherein the annular wall is unitary with said first end cap.12. The filter element as in claim 8, further including an annular side wall with an axially inner end, and an end wall extends radially toward the central axis from said annular side wall, the end wall supporting the first annular threaded portion.13. The filter element as in claim 12, further including an annular gasket supported by and inwardly bounding the in-turned annular flange.14. The filter element as in claim 1, further including a tap plate fixed to the housing, said tap plate having a central circular opening, and said second annular threaded portion is provided around said central opening in said tap plate; and an annular portion of the first end cap is bonded to the first end of the filter media ring, an annular side wall is provided integral with said annular portion and projects axially inward into the media ring towards said second end cap, and a support projects radially toward the central axis from the annular sidewall, and said first annular threaded portion is supported by said radial support.15. The filter element as in claim 1, wherein said first end cap supports the first annular threaded portion.16. The filter element as in claim 1, wherein the threads of the first annual threaded portion have a greater pitch angle than the threads of the second annular threaded portion.17. A filter element for attachement to a filter head, wherein the filter head includes a threaded nipple, and an elongated threaded valve member disposed co-axially with the threaded nipple, with the threads on the valve member having a first thread pitch, and the threads on the threaded nipple having a second thread pitch, different from said first thread pitch, the filter element including: a cylindrical housing and a ring of filtration media disposed within said housing and circumscribing a central axis, said ring of filtration media including first and second ends, and first and second end caps at the first and second ends of the filter media ring, a first annular threaded portion supported within said housing having threads of a first pitch for cooperating with the threads of the nipple, and a second annular threaded portion, co-axially aligned with said first annular threaded portion, having threads of a second pitch, different from said first pitch, for cooperating with the threads of the valve member.18. The filter element as in claim 17, wherein said first end cap supports the first annular threaded portion.19. The filter element as in claim 17, further including a tap plate fixed to the housing, said tap plate having a central circular opening, and said second annular threaded portion is provided around said central opening in said tap plate; and an annular portion of the first end cap is bonded to the first end of the filter media ring, an annular side wall is provided integral with said annular body portion and projects axially inward into the media ring towards said second end cap, and an endwall projects radially toward the central axis from the annular side wall, and said first annular threaded portion is supported by said endwall.20. The filter element as in claim 17, wherein the threads of the first annual threaded portion have a greater pitch angle than the threads of the second annular threaded portion.21. A filter assembly including a filter element and a filter head, the filter head including an inlet and an outlet, a chamber in a bas e of the head in fluid communication with the inlet, a central annular nipple projecting outwardly away from the base with outwardly-directed threads, said nipple having a flow passage in fluid communication with the outlet in the filter head, and a valve member moveably located with respect to said nipple, said valve member normally in a first position preventing flow through the nipple to the outlet, and moveable to a second position allowing flow through the nipple to the outlet, said valve member including a portion projecting outwardly from said nipple that includes radially-outward directed threads, the threads on said outwardly-projecting portion having a pitch angle different than the pitch angle of the threads on the nipple; and the filter element including a cylindrical housing and a ring of filtration media disposed within said housing and circumscribing a central axis, said ring of filtration media including first and second ends, and first and second end caps at the first and second ends of the filter media ring, said first end cap including a threaded sleeve having threads with the same pitch angle as the threads on the valve member, and an annular threaded portion, co-axially aligned with said sleeve, having threads with the same pitch angle as the threads on the nipple, whereby the filter element can be spun-on to the filter head by threaded cooperation between the annular threaded portion and the nipple, and the threads on the sleeve and the threads on the valve member cooperate to cause the valve member to move from the first position to the second position. 22. The filter assembly as in claim 21, wherein said valve member in the filter head includes a circular body, a plurality of elongated fingers projecting axially away from one surface of said body, and an elongated engaging portion extending away from an opposite surface of said body, said engaging portion including the outwardly directed threads of the valve member.23. The filter assembly as in claim 21, wherein the threads on the outwardly-projecting portion of the valve member and on the sleeve have a greater pitch angle than the threads on the nipple and on the annular threaded portion.24. A filter head for a spin-on filter element, the filter head including an inlet and an outlet, a chamber in a base of the head facing the element in fluid communication with the inlet, a central annular nipple with radially-outward directed threads projecting outwardly away from the base, said nipple having a flow passage in fluid communication with the outlet in the filter head, and a valve member moveably located in said nipple, said valve member normally in a first position preventing flow through the nipple to the outlet, and a moveable to a second position allowing flow through the nipple to the outlet, said valve member including a portion projecting outwardly from said nipple that includes radially-outward directed threads, the threads on said outwardly-projecting portion having a pitch angle different than the pitch angle of the threads on the nipple. 25. The filter head as in claim 24, wherein said valve member in the filter head includes a circular body, a plurality of elongated fingers projecting axially away from one surface of said body, and an elongated cylindrical engaging portion extending away from an opposite surface of said body, said engaging portion including the radially outward directed threads of the member.26. The filter head as in claim 24, wherein the threads on the outwardly-projecting portion of the valve member have a greater pitch angle than the threads on the nipple.27. A filter element including a cylindrical housing and a ring filtration media disposed within said housing and circumscribing a central axis, said ring of filtration media including first and second ends, said filter element further including first threaded means for receiving the threads on a nipple of a filter head, said first threaded means having threads of a first
