<p>To provide a can-lid with pop-out-spout, a folded, plastic spout (30) is secured on the underside of a metal can-lid, which is conventionally roll-seamed onto the can-body. This is achieved either by gluing, or by plastic-coating the underside of the lid and heat-sealing the spout to the lid, or by incorporating the tips of the spout's flange in the roll-seamed joint of the can-lid, or other appropriate means. When the can is opened, the spout is released and either unfolds automatically due to the beverage's pressure (in case of carbonated beverages), or can be pulled out by the user. The spout is provided either with a screw-closure (31), or with a twist-off, flick-open closure (41). In one version, the spout is completely covered by the can-lid, which is provided by an opening feature which enables an opening large enough for the spout to pass out. In a further version, the can-lid has a pre-cut aperture, behind which the closure on the spout is locked until the user opens by twisting the closure to free it from aperture. Pilfer-evidence is provided by the can-lid itself, where this has no pre-cut aperture, or by making the handles of the closure pilfer-evident when bent out, or by applying a label (56) across the pre-cut aperture.</p> |
