In what circumstances will a search warrant be sought for a specific, closed container believed to contain contraband?

Finally, no specific closed container believed to contain contraband was seen being placed inside appellant's automobile. By contrast, in United States v. Salazar, 805 F.2d 1394 (9th Cir.1986), a brown shopping bag, from which wrapped packages of cocaine were known to have been distributed, was observed being placed inside a car. In Salazar, we held that prior police knowledge of the specific, closed container required a separate search warrant following the vehicle stop. Facts in this case do not sufficiently parallel the facts of Salazar to warrant a similar conclusion.
