Definitions

  • This invention relates to the surface-finishing of cosmetic and like sticks of pasty material, in particular lipsticks, although it may be applied to sticks of other materials, for example lip salves.
  • a lipstick when initially formed by moulding or casting, may have a dull appearance and this can be transformed by so-called 'flaming', which imparts an attractive glossy appearance to the surface of the mass.
  • This flaming or flame-polishing involves passing the stick momentarily through a flame from a gas burner, sufficient to melt the surface. It will be appreciated that it is a somewhat tricky operation to achieve the necessary melting all over the surface without overheating and possibly distorting some parts of the stick. The process therefore needs careful watching but is regarded as unavoidable in view of the enormous improvement in the appearance of the stick that it achieves.
  • Hot air has been tried but passing a line of lipsticks through a region of air at a high temperature, or through jets of hot air, does not produce a gloss at all; it simply leaves the surface dull, even when the heat input has been sufficient to melt the surface.
  • the invention is based on the unexpected discovery that it is after all possible to produce the desired gloss by the use of hot air, provided it is done in the right way.
  • cosmetic sticks e.g. lipsticks are polished by causing the stick to pass, in a movement along its axis, through a ring of inwardly directed hot air that momentarily heats each annular portion of the stick in turn as it passes through the heated air.
  • the stick could be axially fixed while the ring of inwardly directed hot air traverses its length, but preferably the air supply is fixed and the stick is moved through it.
  • the ring could be in a horizontal plane and the sticks are brought in turn into line with the axis of the ring and then briefly dipped into it and retracted.
  • the ring of inwardly directed air may be formed by individual radial jets but preferably emerges from a straightforward single annular nozzle fed with air passed through an electric heater.
  • the air may flow radially, or be given a degree of tangential twist, and in either case its pressure can be very low, as the total quantity of flow needed is small.
  • the apparatus according to the invention is incorporated as a single stage in any known system for moulding lipsticks in or out of their containers, for example the known Ejectoret system, in which a line of containers is advanced intermittently and molten lipstick mass is poured into a mould through the base of each container in turn, the mould being subsequently removed and the container mechanism being operated to cause the' - now-solidified lipstick to project downwards from it.
  • the invention could be equally well applied to those systems in which the lipstick is cast separately and then inserted in the container.
  • the one essential requirement is that it should be possible to bring the solidified lipstick, either projecting from the container in which it was formed or held in another manner, to the station at which the apparatus according to the invention is present, and then to cause relative axial movement.
  • the lipstick mass is shown at 1. In the example shown it is pointing downwards.
  • the heating apparatus comprises a double-walled hollow cylinder 2 mounted in a heated block 3 in which there is an internal passage 4 leading into the annular space 5 between the two walls.
  • Hot air heated by its passage through the block (which may itself be heated by any convenient means such as a flame or an electric element) enters the annular space 5, flows upwards, and then emerges in a radially inwardly directed jet from an annular slot 6 between the top end of the inner wall and an inturned lip 7 at the top end of the wall. This effectively forms a continuously present horizontal inwardly directed curtain of hot air.
  • the lipstick 1 is brought into alignment with the cylinder 2 and then moved down axially to enter it, each part of the surface of the lipstick therefore passing in turn through the horizontal curtain of air.
  • the temperature of the air, its rate of delivery, and the speed with which the lipstick is moved through it are readily determined by trial and error to impart the required gloss or polish to its surface.
  • the mere exposure of the whole of the lipstick at once to heated air does,not produce a gloss and it was unexpected that this progressive exposure of each successive annular portion in turn should be successful in doing so.
  • the mechanism for moving the lipstick axially into the cylinder is not shown as it can be part of the general system for feeding a succession of lipsticks in the process of manufacturing them.
  • the cylinder has been shown as being stationary, with the lipstick moving vertically downwards into it, it will be understood that the result could be achieved equally well by moving the lipstick upwards or by moving the cylinder and leaving the lipstick stationary if the nature of the overall system makes this easier. Moreover, the movement could be in any attitude, e.g. horizontal.
