Dispensing package having non-removable and non-rotatable dispensing closure |
摘要 |
A dispensing package includes a container having a neck finish with an axis, a non-circular cross section in a plane perpendicular to the axis, and at least one circumferentially extending external engagement element on the neck finish. A closure has a wall received over the container neck finish. The wall has a non-circular cross section corresponding to the non-circular cross section of the neck finish and at least one internal circumferentially extending engagement element in engagement with the external engagement element on the neck finish. The internal and/or external circumferentially extending engagement element has a shallow lead-in angle to enable press-fit of the closure onto the container neck finish and a steep back angle to retard removal of the closure from the neck finish. Rotation of the closure on the neck finish is prevented by the non-circular cross sections of the neck finish and the closure wall. |
