Abstract:
1. A package, comprising: a sleeve including at least one end defining an opening, the sleeve including at least one pair of locking tabs extending therefrom, each locking tab including a locking edge, each locking tab being folded inwards into the opening; and a rigid end cap dimensioned to fit closely within the opening, the end cap including a rim that, when the end cap is inserted into the opening, engages the sleeve end and prevents the end cap from being inserted further into the opening, the end cap including a pair of channels for receiving the pair of locking tabs, each channel having a ledge that is dimensioned and angled to engage the locking edge of each locking tab to prevent the end cap from being removed from the sleeve opening, the sleeve and locking tabs having a strength and resilience that combines with the dimensioning and angling of the ledges to produce a firm locking action when the locking tabs are engaged by the ledges, each of the locking tabs and the channels being shaped such that the end cap is twistable to a position in which the locking tabs are clear of the ledges, thereby releasing the end cap from the sleeve.
