Abstract A capsule or seal device is disclosed which is made from heatshrinkable plastic material. The seal device is not provided initially with a tab before it is applied to a bottle. Before the application of the seal device to the bottle, the cylindrical body of the device possesses two perforated lines which extend from end edge to end edge of the body and is provided at one end edge of the cylindrical body with two notches in the form of arcshaped body portions which continue to the respective perforated or score lines. When the seal or capsule is applied to the bottle and heated to shrink closely to adhere and clinch to the bottle, the tab part located between the two body portions automatically rises up and projects from or is offset with respect to the bottle surface, resulting in forming a tab or lug projection adapted to be grasped by the fingers of a hand when the seal is to be removed from the bottle.
The combination of a bottle having a neck, a closure for said neck, a seal device for said closure and neck, said device comprising a thin-walled tubular body made of heat-shrinkable plastic material shrunk over said neck and closure, said body having opposite upper and lower end edges and being provided with two spaced apart weakened score lines extending into said body material and extending between and to said end edges, to form a tear tab for said seal device between said weakened lines, said body being formed with notches at adjacent ends of said weakened lines located at one of said end edges, and forming a pull lug at one end of the tear tab, said lug projecting from said body and adapted to be grasped by the fingers of a hand to tear the tab when the seal device is to be removed from the neck and closure.
