Abstract
Abstract A cartridge for simultaneously dispensing at least two different materials includes an elongated hollow housing having at least one partition extending laterally and longitudinally thereof to provide at least two chambers for holding the respective materials. A plunger sliding within the housing severs or slits the partition so that it can be stored during operation outside of the respective chambers. The partition may be coiled up or it may be directed laterally around the plunger so that it is stored adjacent an internal wall of the housing.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
169 words
A cartridge for simultaneously dispensing at least two different materials, which cartridge comprises an elongated hollow housing, at least one partition within the housing extending laterally and longitudinally thereof to divide the housing into at least two chambers each for holding one of the different materials,a plunger received in the housing for movement longitudinally thereof and a dispensing orifice in the housing for each of the chambers, the plunger including piston means having a first face for acting on the materials to dispense them from the housing, the piston means including means for sealingly engaging the housing and the partition, characterised in that severing or slitting means are provided following the piston means and spaced from the materials by the piston means to sever the partition from the housing or to slit the partition into at least two parts which remain attached to the housing, means also being provided for storing the severed or slit partition in a manner which does not interfere with the operation of the cartridge.
Claim 2
Dependent Claim
169 words
A cartridge for simultaneously dispensing at least two different materials, which cartridge comprises an elongated hollow housing, at least one partition within the housing extending laterally and longitudinally thereof to divide the housing into at least two chambers each for holding one of the different materials,a plunger received in the housing for movement longitudinally thereof and a dispensing orifice in the housing for each of the chambers, the plunger including piston means having a first face for acting on the materials to dispense them from the housing, the piston means including means for sealingly engaging the housing and the partition, characterised in that severing or slitting means are provided following the piston means and spaced from the materials by the piston means to sever the partition from the housing or to slit the partition into at least two parts which remain attached to the housing, means also being provided for storing the severed or slit partition in a manner which does not interfere with the operation of the cartridge.
Claim 3
Dependent Claim
52 words
A cartridge as claimed in Claim 1 characterised by severing means which comprise a push ring having cutting edges for severing the partition, the push ring supporting a second face of the piston means opposing the first face, the push ring further comprising a container comprising means for storing the severed partition.
Claim 4
Dependent Claim
52 words
A cartridge as claimed in Claim 2 characterised . in that means are provided within the container for coiling up the severed partition therein, and in that the push ring includes a forward wall for supporting the piston means, the forward wall having a slot therein through which the severed partition passes.
Claim 5
Dependent Claim
36 words
A cartridge as claimed in claim 1 characterised in that means are provided for directing the severed partition into an unoccupied space within the housing so as not to interfere with the operation of the cartridge.
Claim 6
Dependent Claim
47 words
A cartridge as claimed in Claim 4 characterised by severing means which comprise a push ring having cutting edges for severing the partition,for example at the longitudinal edges thereof adjacent the housing, the push. ring supporting a second face of the piston means opposing the first face.
Claim 7
Dependent Claim
49 words
A cartridge as claimed in Claim 5 characterised in that the means for directing the partition comprise means supported by the push ring for guiding the partition laterally around a periphery of the push ring so that the partition is stored adjacent an internal longitudinal wall of the housing.
Claim 8
Dependent Claim
30 words
A cartridge as claimed in Claim 5 or 6 characterised in that the severing means further includes a cutting edge arranged to sever the partition into at least two parts.
Claim 9
Dependent Claim
56 words
A cartridge as claimed in Claim 1 characterised by slitting means to slit the partition into at least two parts which remain attached to the housing and by means for folding and directing the parts of the partition into an unoccupied space within the housing so as not to interfere with the operation of the cartridge.
Claim 10
Dependent Claim
33 words
A cartridge as claimed in Claim 8 characterised in that the slitting means comprise a push ring having at least one cutting edge for slitting the partition longitudinally and intermediate its longitudinally edges.
Claim 11
Dependent Claim
25 words
A cartridge as claimed in Claim 9 characterised in that the partition has a non-planar cross-section, such as a U-shaped cross-section, transversely of the housing.
Claim 12
Dependent Claim
92 words
A cartridge as claimed in any of Claims 8 to 10, characterised in that the slitting means slits the partition approximately in half and in that the means for folding and directing the parts of the partition comprise means for first folding a first half of the partition and for then folding the other half of the partition and for directing the half in an overlapped folded relationship around a periphery of the push ring so that the halves of the partition are stored adjacent an internal longitudinal wall of the housing.
