Definitions

  • the present invention relates generally to a process for filling small plastic tubes. More specifically, the present invention relates to a process for filling liquid filled cotton swabs with one or more substances.
  • Filling machines and process are generally designed for filling relatively large containers.
  • Various designs of filling machines and process are available for filling containers with volumes ranging from 55 gallon drums to 1 ounce containers for medications.
  • tube filling process that is capable of reliably and accurately filling the extremely small volume inside a very small diameter tube such as a liquid filled cotton swab.
  • the volume inside a liquid filled cotton swab is typically about 0.1 5 ml.
  • the conventional filling machine and process cannot reliably and accurately fill such a small volume container.
  • conventional filling machines and process are designed to fill only a single substance inside the container.
  • a tube filling process comprising the steps of loading empty plastic tubes into a fixture, sealing one end of said plastic tubes, cutting a score line on said plastic tubes, filling a first substance into said plastic tubes, removing excess amount of said first substance from said plastic tubes to create equal heights of said first substance in said plastic tubes, filling a second substance into said plastic tubes, removing excess amount of said second substance from said plastic tubes to create equal heights of said second substance in said plastic tubes, centrifuge said plastic tubes, and affixing or inserting an applicator tip to an end of said plastic tubes.
  • One or more of the steps may be omitted to produce the desired liquid filled cotton swabs.
  • Figure 1 shows a flow chart of the tube filling process for liquid filled cotton swabs with all the optional steps.
  • the present invention is a process for filling small plastic tubes and liquid filled cotton swabs.
  • the process begins by loading multiple short sections of small diameter plastic tubes with two open ends and with a constant diameter through its length horizontally into one or more fixtures.
  • the small diameter plastic tubes may be fabricated from an extrusion process using polypropylene material and cut to desired length. Each fixture is provided with multiple through holes in it such that one plastic tube will be inserted through each hole.
  • the fixtures allow mass production and automation of the tube filling process.
  • the plastic tubes are restricted from axial movement such as by placing an end of the plastic tubes against a fiat surface.
  • One end of the plastic tubes is then sealed such as by a heat sealing method that melts and seals one end of the plastic tubes.
  • a plug such as a rubber sealing plug, may also be used to seal one end of the plastic tubes.
  • a score line may then be formed near the sealed ends of the plastic tubes. The score line may be formed by a shallow cut with a blade around the circumference of the plastic tubes that does not cut through the wall thickness of the plastic tubes. This step may be omitted entirely if a score line is not desired on the plastic tubes.
  • the plastic tubes are then oriented vertically by rotating the fixture ninety degrees.
  • a first substance which may be a liquid or other viscous substance, is then injected with a small tube into each of the plastic tubes through the remaining open ends which is now oriented upward. If it is desired to have the first substances in each plastic tube to fill to the same height in each plastic tube for aesthetic or other reasons, the excess amount from a predetermined height of the first substance may be removed by vacuum through another small tube inserted into each plastic tube so that the first substance in all the plastic tubes are of the same predetermined height. The removal of the excess amount of the first substance may also be performed simultaneously as the filling process is being completed. A second substance may then be injected into each of the plastic tubes on top of the first substance.
  • the second substance may be a different liquid or a viscous substance such as silicone to prevent evaporation of the first substance. Some of the second substance may also be removed if consistent height is desired between the plastic tubes. The removal of the excess amount of the second substance may also be performed simultaneously as the filling process of the second substance is being completed.
  • the filled plastic tubes may then be centrifuged to remove the air from the substances and to ensure all the substances are near the sealed end of the plastic tubes. The centrifuge may also be performed after filling the plastic tube with the first substance.
  • An applicator tip such as a cotton swab is affixed to or inserted in one end, such as the open end, of the plastic tubes.
  • a second applicator may also be affixed or inserted in the other end, such as the sealed end, of the plastic tubes.
