Abstract: A multiple compartment bag comprises a backing sheet and a cover sheet forming a first compartment open at its top end. A second compartment, usually shorter, is formed by a compartment forming sheet and a closure sheet overlying the cover sheet and one another, these smaller sheets being sealed at their edges to the edges of the two larger sheets to maximize the width of the compartment. The second compartment opening is labyrinthine, formed by the overlap between the compartment forming sheet top portion and the overlying closure sheet bottom portion. The length of the overlap is at least 30% of the total length of the second compartment, as compared to 10% in a prior proposal, and preferably is not more than 70%, thus ensuring safe retention of a bulky article in the second compartment while providing for ease of its insertion and its subsequent easy removal by the recipient.

Abstract: A one piece flat bottomed gusseted bag is provided which may be bottom filled and flat sealed. This structure permits a resealable bag to be filled and sealed without opening the resealable seal. The bag is formed with a revertive pocket at the bottom extending transversely from one side seam of the bag to the other and completely sealed at its ends to the side seams The pocket may be formed before or after sealing. The shape and attachment of the pocket is such as to produce a flat gusseted bottom on the bag when the bag is filled and the pocket forced outwards.
