Motor operated dispensing device with cutting blade

A dispensing device for dispensing viscous material from a cartridge received therein, the dispensing device comprising:

• a main housing;
• a front support;
• a rear plunger assembly spaced apart from the front support by an elongate member to receive and retain the cartridge inserted therebetween, wherein the rear plunger assembly including a plunger plate supported in a plunger housing above a cutting edge and the rear plunger assembly is rotatable about an axis parallel to a longitudinal axis of the elongate member;
• and
• a motor disposed in the main housing and configured to provide a rotational output to the elongate member to move one of the front support and the plunger plate toward each other, thereby urging the cutting edge of the rear plunger assembly against an edge of the cartridge as the plunger plate is driven against an end of the cartridge to expel the viscous material therefrom.

A dispensing device for dispensing a viscous material from a cartridge received therein, the dispensing device comprising:

• a main housing;
• a front support;
• an elongate member coupled to the front support,
• a rear plunger assembly coupled at an opposite end of the elongate member, the cartridge received between the front support and the rear plunger assembly, the rear plunger assembly including a plunger plate and a cutting edge supported in a plunger housing;
• and
• a motor and a gear assembly disposed in the main housing, the motor and the gear assembly engageable with the elongate member so as to move one of the front support and the plunger plate toward each other, thereby urging the cutting edge of the rear plunger assembly against an edge of the cartridge as the plunger plate is driven against an end of the cartridge to expel the viscous material therefrom.
