ABSTRACT:
A device for perforating packaged cigarettes, or the like, including a first housing member provided for defining a receiving area having an opening for receiving a package of cigarettes. A plurality of piercing needles are provided which are moveable relative to the first housing member to pierce the cigarettes. A safety plate member is provided covering the opening of the receiving area. The safety plate member is effective at a first position to block the movement of the piercing needles into the receiving area and at a second position to allow the package of cigarettes into the receiving area. The safety plate member is supported by at least two spring members for biasing the safety plate member towards the first position. The spring members are positioned on a central longitudinal axis of the safety plate member and have spring properties effective to allow steady and smooth movement of the safety plate member. Spacer members are provided for altering the space defined by the receiving area to accommodate various sized cigarette packages. A switch including a switch protrusion guided by a straight guide groove is provided for selectively raising and lowering the package of cigarettes so as to create perforations at different locations on the cigarette. The switch protrusion may be locked at a first and second position and an improved switch pad is provided having grip enhancing raised ridges.
