ABSTRACT:
Disclosed is a product package which includes a sleeve and at least on rigid end cap. The sleeve has longitudinally opposed first and second ends, the first end of the sleeve defining an opening and having at least two locking tabs extending therefrom. The first end of the sleeve also includes a tear strip positioned adjacent to the opening which has been formed using known techniques, such as, microperforation. Each locking tab includes a locking edge and is folded inwards into the opening. A rigid end cap is dimensioned to fit closely within the sleeve opening, the end cap including a rim that, when the end cap is inserted into the opening, engages the first end of the sleeve and prevents the end cap from being inserted further into the opening. The end cap also includes at least one channel for receiving the pair of locking tabs, the at least one channel having a ledge that engages the locking edge of each locking tab to prevent the end cap from being removed from the sleeve opening. The tear strip formed in the sleeve is adapted and configured such that pulling the tear strip allows the rigid end cap to be removed from the sleeve opening. The tear strip can also include a finger tab that is accessible to a user.
