Another cross-category packaging concept: sardine cans. Similar to the cross-category egg carton packaging for egg-shaped products, these flat cans (with old-fashioned keys or pop-top lids) are often thought of as clever containers for any number of fish-shaped products. Where the classic sardine can “keys” are no long practicable, they are sometimes still alluded to in the printed graphics. (Doubtful, however, that the young consumers of, say, “Squishy Fishies” would have any point of reference for cans of fish that are opened with a key.)
Among the cross-categorically packaged products in this round-up: fish-shaped chocolates and candies, fish-shaped catnip toys, fish-shaped children’s toys, beach-scented candles, T-shirt in a tin, bath salts, a novelty canned mermaid, and a sardine can puzzle. (see: Packaging Puzzles)
Also noteworthy is the “Survival-Kit-in-a-Sardine-Can,” — (itself, packaged in a polybag with a header card.) Part of the kit-in-a-can trend, this kit, by virtue of having been fit into a sardine can, is presumed to be a very efficient & compact assortment. There are also other kits in sardine cans.
