A device for piercing a wall of a container and for dispensing pourable material from the container, the device containing: a dispenser housing having an inlet end, an outlet end, and an internal passageway extending from the inlet end to the outlet end; a projection formed on the inlet end of the dispenser housing, the projection having a piercing tip and an outer surface tapering from the piercing tip to a plane of maximum cross section, said outer surface having an inlet port communicating with the internal passageway; an annular pressure grip of elastomeric material surrounding the dispenser housing adjacent to the plane of maximum cross section of the projection, the pressure grip having an outer surface with a cross section conforming to the maximum cross section of the outer surface of the projection and tapering toward the outlet end of the dispenser housing to a plane of minimum cross section; a supporting washer slidably mounted on the dispenser housing between the pressure grip and the outlet end of the housing, the supporting washer being made of the material harder than the material of the pressure grip; and means for urging the supporting washer toward the pressure grip with sufficient force to compress the annular pressure grip axially and to correspondingly expand the pressure grip radially.
