Definitions
- the invention relates to methods and apparatus used in forming liquid filled capsules.
- the wedge member 152 comprises opposed arcuate faces 154 that are connected by opposed planar side faces 156,158.
- the arcuate faces 154 are configured such that the wedge members 150,152 have an arcuate tapering cross-section to allow them to fit with a small clearance into the nip of moulding drums 132,134 having a predetermined diameter, with the arcuate faces 154 facing the respective cylindrical surfaces of the moulding drums.
- the outermost recess 164 (as viewed in Figure 6) is provided with a line of apertures 166 at spaced intervals along its length. As shown in Figure 4, apertures 166 are arranged so that they are aligned with the respective edge regions of the film.
- the apertures 166 are connected by internal passages (not shown) of the wedge member 152 with a pipe 168 ( Figure 3) that is connected with a pressurised gas supply.
- the gas supply is preferably pressurised nitrogen, which has the benefit of being inert, although, in principle, any suitable gas may be used.
- the lower end 210 of the transverse member 206 has opposed arcuate faces similar to the arcuate faces 212 of the wedge members 202,204. This is so that it can fit into the nip in the same way as the wedge members.
- an elongate slot 214 is defined in the lowermost edge of the transverse member. Passages 216 are provided to connect the slot 214 with the reservoir 130. As shown in Figures 8 and 9, one or more overflows 216 is/are provided in one or both wedge members 202,204.
- the operation of the liquid filling apparatus 200 is similar to that of the apparatus 100.
- Pressurised gas preferably nitrogen, is supplied to apertures 220 in the arcuate faces 212 via passages 222 to provide a gas barrier between the arcuate faces and the cylindrical surfaces of moulding drums.
- Liquid is supplied to the nip via the passages 216 and elongate slot 214. Some liquid will flow up over the lower portions 210 of the transverse member 206 to the level of the overflow(s) 216.
- the pressure of the gas supply is adjusted to just match the hydrostatic pressure in the nip so that liquid cannot escape sideways between the arcuate faces 212 and the cylindrical surfaces of the drums 132,134. If desired, a gas blanket can be created above the lower portions 210 of the transverse member to separate the liquid in the nip from atmosphere.
- Nitrogen is the preferred gas for many applications, because it is inert. This is advantageous when filling capsules with fish oils, or some vegetable oils, because such oils can oxidise if they come into contact with air, resulting on an unpleasant rancid taste.
- the moulding drums 132,134 are supported in parallel side-by-side relationship with a small gap therebetween. This is not essential. There does not have to be a controlled gap.
- the shaft of one moulding drum may be fixed so as to substantially prevent movement in a horizontal plane, while the shaft of the other drum is mounted so as to be movable in that plane.
- a biassing force is applied to the movable shaft to press the respective moulding drum toward the "fixed" drum. This provides the possibility of varying the force applied to the films in the nip by varying the biassing force and so being able to control the nip-force independently of the thickness of the films.
- the nozzle 182 does not have to be a fishtail nozzle.
- Other shaped nozzles, or a plurality of nozzles may be used as desired.
- the choice of nozzle(s) may be varied to take account of the characteristics of the filling liquid.
