Claims7
Apparatus useful for filling a dispenser having a body formed with a tubular cavity of substantially uniform cross section, said apparatus comprising:
- an injection head that fits loosely into said tubular cavity and includes at its outlet end a honeycomb formed with a plurality of axial channels of substantially equal size, said honeycomb being divided into two or more sets of said channels.
An injection head useful for filling a tubular cavity of uniform cross section, which cavity is formed in the body of a dispenser, said injection head comprising:
- a hollow tube that loosely fits into said tubular cavity,
- a honeycomb mounted at one end of the hollow of said tube and formed with a plurality of axial channels of substantially equal size, and
- a pair of walls extending from said honeycomb to the other end of said tube and subdividing the hollow of said tube into (1) a first compartment including a first contiguous set of said channels, (2) a second compartment including a second contiguous set of said channels, and (3) a third compartment including a third contiguous set of said channels which are small in number compared to said first and second sets and lie in separating relationship between said first and second sets, said walls being canted so that said first, second and third compartments are of substantially equal volume.
