Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
311 words
An apparatus for automatically dispensing blister packs which comprises a base plate supporting in position thereon a blister pack strip container holding therein blister pack strips, said base plate being provided with a slot; a discharging member for advancing a strip of blister packs one after another, the distal end of said discharging member extending upward through said slot; said strips of blister packs each having a relatively smooth surface on one side and a plurality of projections which serve as compartments for pharmaceutical articles and are axially arranged at substantially equal spacings on the opposite side, said strips of blister packs being stacked in said container with the projections face down and with the relatively smooth surfaces face up, said container having at the bottom thereof an opening which communicates with the slot of the base plate when said container is set in position on said base plate, said container further having a blister pack exit in communication with said opening, said exit being provided so as to be located in the path of movement of the discharging member when said container is set in position on said base plate; means for moving said discharging member repeatedly a specified distance back and forth; means for effecting engagement of said discharging member in its forward travel with one of said projections of a blister pack strip to advance the lowermost blister pack strip a predetermined amount and for preventing in its backward travel past the projections of blister pack strip any arresting or retracting of the strip of blister packs by said discharging member; cutter means for cutting off the leading portion of the strip of blister packs discharged from said container; and means for controlling the cutter means to bring the cutter edge into operation when the cumulative amount of movement of the discharging member has reached a predetermined value.
Claim 2
Independent Claim
311 words
An apparatus for automatically dispensing blister packs which comprises a base plate supporting in position thereon a blister pack strip container holding therein blister pack strips, said base plate being provided with a slot; a discharging member for advancing a strip of blister packs one after another, the distal end of said discharging member extending upward through said slot; said strips of blister packs each having a relatively smooth surface on one side and a plurality of projections which serve as compartments for pharmaceutical articles and are axially arranged at substantially equal spacings on the opposite side, said strips of blister packs being stacked in said container with the projections face down and with the relatively smooth surfaces face up, said container having at the bottom thereof an opening which communicates with the slot of the base plate when said container is set in position on said base plate, said container further having a blister pack exit in communication with said opening, said exit being provided so as to be located in the path of movement of the discharging member when said container is set in position on said base plate; means for moving said discharging member repeatedly a specified distance back and forth; means for effecting engagement of said discharging member in its forward travel with one of said projections of a blister pack strip to advance the lowermost blister pack strip a predetermined amount and for preventing in its backward travel past the projections of blister pack strip any arresting or retracting of the strip of blister packs by said discharging member; cutter means for cutting off the leading portion of the strip of blister packs discharged from said container; and means for controlling the cutter means to bring the cutter edge into operation when the cumulative amount of movement of the discharging member has reached a predetermined value.
Claim 3
Dependent Claim
73 words
The apparatus as set forth in claim 1 wherein the discharging member comprises a discharging pawl pivoted to a motion member which is repeatedly and linearly movable a specified distance back and forth, said discharging pawl being movable past the projection of the blister pack without being thereby arrested when retracted by said motion member and engageable with the projection to advance the strip of blister packs when advanced by the motion member.
Claim 4
Dependent Claim
71 words
The apparatus as set forth in claim 1 wherein the discharging member comprises a discharging pawl pivoted to a lever pivotally repeatedly movable back and forth about an axis through a specified angle, the discharging pawl being movable past the projection of the blister pack without being thereby arrested when retracted by the lever and engageable with the projection to advance the strip of blister packs when advanced by the lever.
