Abstract
Abstract Sealed containers comprising in combination a cylindrical packing member and a container having a closing means. The cylindrical packing member is made from a heat-shrinkable synthetic resin and has printed matter appearing thereon at the required location. The packing member also contains a circumferential tearing line, preferably perforated, at a location above the printed matter. A heat-sensitive adhesive is applied on the inner surface of the packing member at a location below the tearing line and becomes tacky when the packing member is heated to a temperature sufficient to cause the shrinking of said packing member about the container whereby a closely fitting packing member is formed about the container. When the upper portion is removed, and lower portion containing the printed matter remains adhered to the container.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
136 words
A sealed container comprising in combination a cylindrical packing member and a container, said container having a closing means and said cylindrical packing member consisting essentially of a heat-shrinkable synthetic resin and having printed matter thereon at the required location and said packing member being provided with a circumferential tearing line at a location above the printed matter and a projecting tongue at its uppermost edge and longitudinal tearing lines extended from the root of said tongue to said circumferential tearing line, said packing member further having a heat-sensitive adhesive applied on its inner surface at a location below said tearing line and said adhesive becoming tacky when said packing member is heated to a temperature sufficient to cause the shrinking thereof thereby resulting in the formation of a closely fitting packing member about said container.
Claim 2
Dependent Claim
136 words
A sealed container comprising in combination a cylindrical packing member and a container, said container having a closing means and said cylindrical packing member consisting essentially of a heat-shrinkable synthetic resin and having printed matter thereon at the required location and said packing member being provided with a circumferential tearing line at a location above the printed matter and a projecting tongue at its uppermost edge and longitudinal tearing lines extended from the root of said tongue to said circumferential tearing line, said packing member further having a heat-sensitive adhesive applied on its inner surface at a location below said tearing line and said adhesive becoming tacky when said packing member is heated to a temperature sufficient to cause the shrinking thereof thereby resulting in the formation of a closely fitting packing member about said container.
Claim 3
Dependent Claim
14 words
A sealed container according to claim 1 wherein said circumferential tearing line is perforated.
Claim 4
Dependent Claim
26 words
A sealed container according to claim 2 wherein said heat-sensitive adhesive is applied onto the inner surface of said cylindrical packing member in a striped pattern.
Claim 5
Dependent Claim
43 words
A sealed container according to claim 1 wherein the upper and lower edge portions of the packing member is bent radially inwardly so as to be closely fitted over the top circumference of said closing means and the bottom circumference of the container.
Claim 6
Dependent Claim
30 words
A sealed container according to claim 1 wherein the height and inner diameter of the cylindrical packing is slightly greater than the height and maximum outer diameter of the container.
