Abstract

Abstract A removable liner structure for a crown closure consists of a sandwich wherein printed matter is contained between two layers constituting the sandwich. The inside of the rigid shell of the crown is provided with a varnish coat followed by an adherence coating in the area of the skirt. This is then followed by the sandwich structure constituting the removable liner with the indicia between the two layers forming the sandwich. A ringseal is then provided over the sandwich.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 98 words
A crown closure, comprising: a. an internally varnished rigid shell; b. a liner structure disposed within the rigid shell; c. material providing indicia adherent to the liner structure in the central portion of the rigid shell; wherein the improvement comprises: d. an adherence coating between the varnish and the liner structure about the skirt portion of the rigid shell such that only the portion of the liner structure with the indicia adherent thereto in the central portion of the rigid shell may be removed therefrom, the remainder of the liner structure being firmly secured to the rigid shell.
Claim 2
Dependent Claim 98 words
A crown closure, comprising: a. an internally varnished rigid shell; b. a liner structure disposed within the rigid shell; c. material providing indicia adherent to the liner structure in the central portion of the rigid shell; wherein the improvement comprises: d. an adherence coating between the varnish and the liner structure about the skirt portion of the rigid shell such that only the portion of the liner structure with the indicia adherent thereto in the central portion of the rigid shell may be removed therefrom, the remainder of the liner structure being firmly secured to the rigid shell.
Claim 3
Dependent Claim 158 words
A crown closure, comprising: a. a rigid shell having a central portion and a skirt portion about the periphery of said central portion; b. a varnish coating in the interior of said rigid shell; c. an adherence coating upon said varnish coating only about said skirt portion of said rigid shell so as to leave a portion of said varnish coating uncovered within said skirt portion; d. a first layer upon said adherence coating and upon the uncovered portion of varnish coating; e. a second layer upon said first layer; f. means defining indicia between said first and second layers; and g. sealing means upon said second layer only about said central portion of said rigid shell, said first and second layers, said means defining indicia and said sealing means being adapted to be separated from said rigid shell only about said central portion thereof at the portion of said varnish coating not covered by said adherence coating.
Claim 4
Dependent Claim 158 words
A crown closure, comprising: a. a rigid shell having a central portion and a skirt portion about the periphery of said central portion; b. a varnish coating in the interior of said rigid shell; c. an adherence coating upon said varnish coating only about said skirt portion of said rigid shell so as to leave a portion of said varnish coating uncovered within said skirt portion; d. a first layer upon said adherence coating and upon the uncovered portion of varnish coating; e. a second layer upon said first layer; f. means defining indicia between said first and second layers; and g. sealing means upon said second layer only about said central portion of said rigid shell, said first and second layers, said means defining indicia and said sealing means being adapted to be separated from said rigid shell only about said central portion thereof at the portion of said varnish coating not covered by said adherence coating.
Claim 5
Independent Claim 129 words
A method of making a crown closure, comprising the steps of: a. applying a varnish coating to one face of a metal sheet; b. applying an adherence coating upon the varnish coating only upon that portion of the metal sheet which is to form the skirt of the crown closure; c. applying a liner structure upon the adherence coating and upon that portion of the varnish coating that is not covered by the adherence coating; and d. forming the metal sheet into a crown closure such that the adherence coating is located only in the area of the skirt portion of the crown closure in order that the liner structure will securely adhere to the skirt portion but not securely adhere to the central region of the crown closure.
Claim 6
Independent Claim 129 words
A method of making a crown closure, comprising the steps of: a. applying a varnish coating to one face of a metal sheet; b. applying an adherence coating upon the varnish coating only upon that portion of the metal sheet which is to form the skirt of the crown closure; c. applying a liner structure upon the adherence coating and upon that portion of the varnish coating that is not covered by the adherence coating; and d. forming the metal sheet into a crown closure such that the adherence coating is located only in the area of the skirt portion of the crown closure in order that the liner structure will securely adhere to the skirt portion but not securely adhere to the central region of the crown closure.
