Process for the manufacture of a cosmetic or pharmaceutical stick

Claim 2

A process for the manufacture of a solid, wax-like cosmetic or pharmaceutical stick product, which comprises the steps of attaching a pouring cap closure to the upper portion of a suitable container for said stick, said container being open at the bottom; inverting said container body and filling from the bottom thereof with a premeasured quantity of said cosmetic or pharmaceutical composition in a molten state; cooling said composition to form within the body of said container a solid, wax-like stick, inserting into the bottom portion of said container body, a push-up device, re-inverting the container and removing said pouring cap; moving said stick into contact with said push-up device and affixing a cap to said container.

Claim 3

The process according to claim 1 wherein said container is a cylindrical body threaded on the upper portion to receive a cap and having a flange incorporated in the bottom as a seat for said push-up device.

Claim 4

A process as in claim 1 wherein a heated staking device is inserted into the bottom of said solidified stick to melt the stick in the vicinity of any voids and cause filling thereof, and said stick is again cooled, prior to inserting said push-up device.

Claim 5

A process as in claim 1 wherein said stick is pulled into contact with said push-up device by applying a vacuum through at least one hole through the base of said push-up device.

Claim 6

A process for the manufacture of a solid, wax-like cosmetic or pharmaceutical stick, having a custom molded upper surface, which comprises the steps of attaching a pouring cap closure to the upper portion of a suitable container for said stick, said container being open at the bottom, said pouring cap having therein a mold, said mold forming the shape and design of the upper surface of the stick; inverting said container body and filling from the bottom thereof with a premeasured quantity of the molten cosmetic or pharmaceutical composition; cooling said composition to form within the body of said container a solid, wax-like stick having a custom molded upper surface; inserting into the bottom portion of said container body a push-up device, by means of a reducing collar attached removably to the bottom of said body, re-inverting the container and removing said pouring cap; thereafter moving said stick into contact with said push-up device and affixing a cap to said container.

Claim 7

A process for the manufacture of a solid, wax-like cosmetic or pharmaceutical stick, having a custom molded upper surface, which comprises the steps of attaching a pouring cap closure to the upper portion of a suitable container for said stick, said container being open at the bottom, said pouring cap having therein a mold, said mold forming the shape and design of the upper surface of the stick; inverting said container body and filling from the bottom thereof with a premeasured quantity of the molten cosmetic or pharmaceutical composition; cooling said composition to form within the body of said container a solid, wax-like stick having a custom molded upper surface; inserting into the bottom portion of said container body a push-up device, by means of a reducing collar attached removably to the bottom of said body, re-inverting the container and removing said pouring cap; thereafter moving said stick into contact with said push-up device and affixing a cap to said container.

Claim 8

A process for the manufacture of a solid, wax-like cosmetic or pharmaceutical stick, having a custom molded upper surface, which comprises the steps of (1) attaching a pouring cap closure to the upper portion of a suitable container for said stick, said container being open at the bottom, said pouring cap having inserted therein a removable mold, said mold forming the shape and design of the upper surface of the stick; (2) inverting said container body and filling from the bottom thereof with a premeasured quantity of the molten cosmetic or pharmaceutical composition; (3) cooling said composition to form within the body of said container a solid, wax-like stick having a custom molded upper surface; (4) inserting into the bottom of said stick an electrically heated prong, whereby voids and air bubbles near the surface are dissipated by melting the composition and allowing the molten composition to flow into and fill said voids; (5) allowing the molten composition to re-solidify; (6) inserting into the bottom portion of said container a single piece plastic push-up device, by means of a reducing collar attached removably to said body, said push-up device having a plurality of small holes drilled therethru; (7) re-inverting the container and removing said pouring cap; (8) applying a vacuum to the bottom of said container, whereby said stick is pulled into contact with said push-up device by means of the holes drilled therethru; and (9) affixing a cap to said container.

Claim 9

A process for the manufacture of a solid, wax-like cosmetic or pharmaceutical stick, having a custom molded upper surface, which comprises the steps of (1) attaching a pouring cap closure to the upper portion of a suitable container for said stick, said container being open at the bottom, said pouring cap having inserted therein a removable mold, said mold forming the shape and design of the upper surface of the stick; (2) inverting said container body and filling from the bottom thereof with a premeasured quantity of the molten cosmetic or pharmaceutical composition; (3) cooling said composition to form within the body of said container a solid, wax-like stick having a custom molded upper surface; (4) inserting into the bottom of said stick an electrically heated prong, whereby voids and air bubbles near the surface are dissipated by melting the composition and allowing the molten composition to flow into and fill said voids; (5) allowing the molten composition to re-solidify; (6) inserting into the bottom portion of said container a single piece plastic push-up device, by means of a reducing collar attached removably to said body, said push-up device having a plurality of small holes drilled therethru; (7) re-inverting the container and removing said pouring cap; (8) applying a vacuum to the bottom of said container, whereby said stick is pulled into contact with said push-up device by means of the holes drilled therethru; and (9) affixing a cap to said container.
