Abstract
A compact dispensing tube opener for accessing contents of a dispensing tube having a dispensing tip and an inner seal. The opener includes a housing with first and second passageways therein meeting at an angle at an intersection. A blade carriage is movable in the second passageway and across the intersection at one end thereof, a manually accessible portion at an opposite end thereof extending from the housing. A cooperative guide structure at the housing and the blade carriage maintains carriage slidability within the housing during use without binding. Return springs are maintained in the housing for returning the carriage after use. A dispenser tube tip locator is slidably maintained at the housing adjacent to an opening to the first passageway and has plurality of angled passages therethrough each with a different diameter. A lance is mounted at the housing for puncturing the seal, and is pivotable into and out of a channel defined crosswise in the housing.
