초록 ▼

A flexible package for a product includes a resealable closure for resealing one portion of the package to an opposing portion of the package. The resealable closure is formed by applying a layer of pressure-sensitive adhesive on the inner surface of at least one of the opposing portions of the package, and applying a layer of cohesive to the inner surface of both of the opposing portions so that the pressure-sensitive adhesive layer is covered by a layer of cohesive. The pressure-sensitive adhesive has a greater affinity for adhering to the cohesive than to the inner surface of the package. Accordingly, pressure-sensitive adhesive is detached from the inner surface of the package when the opposing portions are pulled apart, and the portions can be resealed by pressing the portions back together to cause the pressure-sensitive adhesive to adhere to the portion from which is was detached.

[ What is claimed is:] [1.] A resealable package for a product, comprising:a flexible container formed from a generally rectangular flexible sheet having inner and outer surfaces, two opposite longitudinal edges, and top and bottom transverse edges, the sheet being wrapped to form a generally tubular structure having a portion of the inner surface adjacent one longitudinal edge sealed to a corresponding portion of the inner surface adjacent the other longitudinal edge to define a longitudinal seal, the tubular structure having portions of the inner surface adjacent the bottom edge sealed to other portions of the inner surface adjacent the bottom edge to define a bottom seal, and the container including a top end which defines an opening for removal of the product from the tubular structure, the sheet defining a pair of opposite flexible side walls having opposing inner surfaces, the side walls having edge portions positionable in overlying relation, the edge portions being separable from each other to create said opening in the container; andan openable and resealable seal along the opening, the seal being defined by the edge portions of the side walls placed in confronting relation with each other and adhesively sealed together, a layer of pressure sensitive adhesive being applied to the inner surface of at least one of the edge portions, and a layer of cohesive being applied to the inner surfaces of both edge portions and covering the pressure-sensitive adhesive, the cohesive layers of the edge portions being sealed together to form the resealable seal;the pressure sensitive adhesive having a greater affinity for adhering to the cohesive than to the inner surface of the package, whereby initial opening of the resealable seal causes regions of the cohesive layers on the two side walls to remain adhered together such that regions of pressure-sensitive adhesive are detached from one side wall and remain with the other side wall, and whereby the top seal may be resealed by pressing the edge portions of the two side walls together to cause the detached regions of pressure-sensitive adhesive to be reattached to the one side wall;wherein the layer of pressure-sensitive adhesive is applied in a pattern extending transversely along the top edge of the sheet, and wherein a strip of cohesive is applied to a portion of the inner surface which is not covered by the pressure-sensitive adhesive layer and which extends transversely along substantially the entire transverse width of the sheet, whereby the strength of the original top seal is enhanced by the strip of cohesive which adheres to itself upon initial sealing of the top seal.
