Claims
- 1. A method of making a lipstick sampler using an apparatus comprising a reservoir containing molten fluid lipstick wax material, a spindle which is disposed above the reservoir and which is advanceable toward and retractable away from the reservoir, and a plastic cup-shaped form having a tip, and having an aperture in the tip comprising the steps of:
- a) applying the plastic cup-shaped form onto the spindle,
- b) advancing the spindle to dip the plastic cup-shaped form into the reservoir containing molten fluid lipstick wax material and submerging the tip of the plastic cup-shaped form in the molten fluid lipstick wax material contained therein for a time interval to form a coating of said molten fluid lipstick wax material on the plastic cup-shaped form and thereby form a coated plastic cup-shaped form,
- c) retracting the spindle and the coated plastic cup-shaped form from the reservoir, an excess of said molten fluid lipstick wax material forming on the tip at the aperture,
- d) drawing gas inwardly through said aperture of the coated plastic cup-shaped form while said molten fluid lipstick wax material is still fluid to thereby draw said excess of said molten fluid lipstick wax material on the tip into the interior of the spindle, thereby to minimize excess accumulation of the molten fluid lipstick wax material on the tip of the plastic cup-shaped form, and
- e) cooling the molten fluid lipstick wax material on the coated plastic cup-shaped form to solidify the molten fluid lipstick wax material on the coated plastic cup-shaped form.
- 2. The method as set forth in claim 1, wherein:
- the step of dipping the plastic cup-shaped form into the molten fluid lipstick wax material is effected when the temperature of the molten fluid lipstick wax material is between. 130 degrees F and 200 degrees F.
- 3. The method as set forth in claim 1, wherein:
- the step of cooling the molten fluid lipstick wax material on the coated plastic cup-shaped form to solidify the molten fluid lipstick wax material on the coated plastic cup-shaped form comprises cooling the molten fluid lipstick wax material to the point of solidification within a time interval of less than 10 seconds.
- 4. The method as set forth in claim 1, wherein:
- said excess of said molten fluid lipstick wax material is in the form of a droplet and said step of drawing gas inwardly is performed by means of a vacuum.
- 5. The method as set forth in claim 1, wherein:
- the time interval during which the plastic cup-shaped form is in contact with the molten fluid lipstick wax material is greater than 0.5 seconds, which provides said coating having a reduced thickness.
- 6. The method as set forth in claim 4, wherein the interior of the spindle is hollow and comprises a vacuum line, and wherein:
- the droplet that is drawn into the interior of the spindle is collected through the vacuum line and thereafter is returned to the reservoir.
- 7. The method as set forth in claim 1, wherein:
- the thickness of the coating on the coated cup-shaped form is a function of the temperature of the molten fluid lipstick wax material in the reservoir.
- 8. The method as set forth in claim 1, wherein:
- the thickness of the coating on the coated cup-shaped form is a function of the time interval during which the cup-shaped form is in contact with the molten fluid lipstick wax material in the reservoir.
- 9. A method of making a lipstick sampler using an apparatus comprising a reservoir containing molten fluid lipstick wax material, a spindle which is disposed above the reservoir and which is advanceable toward and retractable away from the reservoir, and a plastic cup-shaped form having a tip, and having an aperture in the tip comprising the steps of:
- a) applying the plastic cup-shaped form onto the spindle,
- b) advancing the spindle to dip the plastic cup-shaped form into the reservoir containing molten fluid lipstick wax material and submerging the tip of the plastic cup-shaped form in the molten fluid lipstick wax material contained therein for a time interval to form a coating of said molten fluid lipstick wax material on the plastic cup-shaped form and thereby form a coated plastic cup-shaped form,
- c) retracting the spindle and the coated plastic cup-shaped form from the reservoir, an excess of said molten fluid lipstick wax material forming on the tip at the aperture,
- d) effecting a flow of gas through the aperture while said molten fluid lipstick wax material on said coated cup-shaped form is still fluid, to thereby effectively disperse excess accumulation of the molten fluid lipstick wax material from the coated cup-shaped form at the vicinity of said aperture, and
- e) cooling the molten fluid lipstick wax material on the coated plastic cup-shaped form to solidify the molten fluid lipstick wax material on the coated plastic cup-shaped form.
