In the packaging of certain products such as liquid chlorine bleach and the like, it is desirable to provide a single use package which can not be reused and yet which will have an indication of possible tampering.
Accordingly among the objectives of the present invention are to provide a single usage tamper resistant package which will adequately seal the contents, will not be resealable, and wherein neither the sealing device nor the closure can be reused and wherein preferably a portion of the closure remains with the bottle or container.
In accordance with the invention, the non-reusable temper indicating package comprises a container and a closure. The container has a body portion and a neck portion defining an opening and the neck portion has an annular bead spaced from the end of the neck. The closure has a top wall and a peripheral skirt and a retention and holding bead on the skirt adapted to engage the annular bead on the container. The closure includes spaced score lines on the skirt and a portion of the top wall defining a severable portion between the score lines such that when the severable portion is pulled outwardly and upwardly, the closure is severed along the score lines. A foil sheet has a layer of thermoplastic material on each surface thereof and is thermally bonded to the upper end of the container. A liner ring overlies the foil sheet and is thermally bonded to the thermoplastic material of the foil. The top wall has a depending portion thermally bonded to the thermoplastic material on the foil sheet such that when the severable portion of the skirt and top wall are severed along the score lines, the depending portion of the closure tears the foil sheet to provide access to the contents and the foil sheet can not be reused and the closure can not be reused to reseal a container. In a modified form, the liner is eliminated and the depending portion is thermally bonded directly to foil sheet.
