Abstract
Abstract A sealed container has a closure which includes a label attached to an outturned flange of the container by a peripheral band of pressure sensitive adhesive on the label such that the label is adapted to be peeled back at one of its corners to dispense articles one at a time from the container and to be then pressed back into place until another article is to be dispensed, the closure being produced by a method which uses a backing sheet to present a path attached to the label by such adhesive and disposed within the confines of the band for protecting the articles against contact with the adhesive. A single coating of the pressure sensitive adhesive is initially used to laminate the backing sheet with a label sheet and the patches are then preformed by die cutting the backing sheet. The labels may also be preformed by die cutting and/or by die perforating of the label sheet. The waste materials of the sheets are then removed, presenting the closures, each consisting of a patch still glued to the label and exposing only the pressure sensitive adhesive band on the label around the patch.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
181 words
In a method of packaging through use of containers having access openings surrounded by outwardly extending flanges, said method including the steps of: laminating a pair of sheets by use of a pressure sensitive adhesive between the proximal inner faces thereof; thereupon cutting one Of said sheets while the same are stuck together to present a plurality of individual protective patches attached to said inner face of the other sheet by said adhesive; separating said sheets such as to leave only the patches connected by said adhesive to said inner face of said other sheet with each patch surrounded by a band of said adhesive remaining on said inner face of said other sheet; closing said openings of a bank of said containers by placing the patches over the openings of corresponding containers and pressing the bands into attachment with proximal flanges of the containers; and subdividing said other sheet to present an outer cover attached by its band to the flange of each container respectively with each cover having a patch still connected to said inner face by said adhesive.
Claim 2
Dependent Claim
181 words
In a method of packaging through use of containers having access openings surrounded by outwardly extending flanges, said method including the steps of: laminating a pair of sheets by use of a pressure sensitive adhesive between the proximal inner faces thereof; thereupon cutting one Of said sheets while the same are stuck together to present a plurality of individual protective patches attached to said inner face of the other sheet by said adhesive; separating said sheets such as to leave only the patches connected by said adhesive to said inner face of said other sheet with each patch surrounded by a band of said adhesive remaining on said inner face of said other sheet; closing said openings of a bank of said containers by placing the patches over the openings of corresponding containers and pressing the bands into attachment with proximal flanges of the containers; and subdividing said other sheet to present an outer cover attached by its band to the flange of each container respectively with each cover having a patch still connected to said inner face by said adhesive.
Claim 3
Dependent Claim
181 words
In a method of packaging through use of containers having access openings surrounded by outwardly extending flanges, said method including the steps of: laminating a pair of sheets by use of a pressure sensitive adhesive between the proximal inner faces thereof; thereupon cutting one Of said sheets while the same are stuck together to present a plurality of individual protective patches attached to said inner face of the other sheet by said adhesive; separating said sheets such as to leave only the patches connected by said adhesive to said inner face of said other sheet with each patch surrounded by a band of said adhesive remaining on said inner face of said other sheet; closing said openings of a bank of said containers by placing the patches over the openings of corresponding containers and pressing the bands into attachment with proximal flanges of the containers; and subdividing said other sheet to present an outer cover attached by its band to the flange of each container respectively with each cover having a patch still connected to said inner face by said adhesive.
Claim 4
Dependent Claim
181 words
In a method of packaging through use of containers having access openings surrounded by outwardly extending flanges, said method including the steps of: laminating a pair of sheets by use of a pressure sensitive adhesive between the proximal inner faces thereof; thereupon cutting one Of said sheets while the same are stuck together to present a plurality of individual protective patches attached to said inner face of the other sheet by said adhesive; separating said sheets such as to leave only the patches connected by said adhesive to said inner face of said other sheet with each patch surrounded by a band of said adhesive remaining on said inner face of said other sheet; closing said openings of a bank of said containers by placing the patches over the openings of corresponding containers and pressing the bands into attachment with proximal flanges of the containers; and subdividing said other sheet to present an outer cover attached by its band to the flange of each container respectively with each cover having a patch still connected to said inner face by said adhesive.
Claim 5
Dependent Claim
37 words
In a method of packaging as claimed in claim 1 wherein prior to lamination of said sheets said inner face of said one sheet is first coated with a releasing agent and then coated with said adhesive.
Claim 6
Dependent Claim
50 words
In a method of packaging as claimed in claim 1 wherein prior to the separation step, and while the sheets are stuck together, said other sheet is cut to present a series of elongated strips, each strip being subdivided transversely thereof after the openings are closed to present said covers.
Claim 7
Dependent Claim
60 words
In a method of packaging as claimed in claim 1 wherein prior to the separation step, and while the sheets are stuck together, said other sheet is cut to present a series of elongated strips and perforated transversely of said strips to present a plurality of said covers, each strip being subdivided along the perforations after the openings are closed.
