Abstract: An easily removable label for use in connection with a container to be recycled (e.g. bottle or can). The label has first and second faces. Indicia is provided on the first face and a coating of repositionable adhesive is applied to the second face. The label is also provided with leading and trailing edges which cooperate to form an overlapping area with permanent adhesive which secures one face of the label to the other while at the same time precluding contact of the permanent adhesive with the container. The label may be provided with a perforation line adjacent the overlapping area so that the label may be conveniently separated from the container. The face of the label may be coated with permanent pressure sensitive adhesive release material, and a number of labels provided in a pad. The label provides a lasting adhesion between the container and the label but yet will not leave any significant residue of permanent adhesive once the label is removed.

Abstract: Thermosensitive linerless labels (either thermal labels or thermal transfer labels) which can be used with food products contain a pressure sensitive adhesive covering one face of a substrate having a thermosensitive layer on the opposite face, and a release coat covering the thermosensitive layer. The release coating is preferably applied directly to the thermosensitive layer, and preferably is prepared by application and then drying of a formulation containing between about 5-25 parts chromium pentahydroxy (tetradecanoato) di-, and about 75-95% water or alcohol. Alternatively, the release coating may be a UV curable silicone with about 1-3% by weight photoinitiator. After the coatings are applied, the stock is dried in a manner that will not adversely affect the thermosensitive layer, e.g. by ultraviolet rays, or air drying at a temperature of less than 150.degree. F. A web comprising the substrate may be slit into individual rolls, and perfing or die cutting is practiced to form individual labels.

Abstract: An adhesive applicator of the gravure-type is provided for continuously applying spots of adhesive onto a travelling web with the use of a roller of the intaglio type. A filling device having a spring loaded shoe element bearing against the roller fills the cavities of the roller with adhesive under pressure from a closed adhesive reservoir. The web is moved by a pin wheel disposed adjacent the roller, and spots of adhesive from the filled cavities are continuously applied to the web as it is intermittently forced to track the applicator roller by means of spaced pads provided on the wheel.
