FIELD OF THE INVENTION
The present invention generally relates to systems for applying labels to products. More particularly, it relates to an applicator system for applying a label on optical discs. It also relates to a method for applying a label on optical discs using such an applicator system. It also relates to the sheets from which the labels may be extracted.
BACKGROUND OF THE INVENTION
Several different systems have been developed to allow users of recordable optical discs to customize their discs through application of a label thereon.
U.S. Pat. No. 7,302,982 discloses a label applicator including a support surface having a central area and curving downwardly from the central area. The curved surface flattens out as the article is pressed down, allowing the label to be smoothly applied to the article.
U.S. Pat. No. 6,585,021 teaches a CD label applicator kit including a case, a support device and an applicator tool. The support device has an alignment post, a hub and a spring. The alignment post is fixed to an outer wall of the cover and extends outwardly through the opening. The spring biases the hub to a raised position in which the disk-receiving surface is above the label plate.
U.S. Pat. No. 6,405,777 discloses a compact cylindrical cap labelling device for applying self adhesive labels onto optical discs. The structure of the device results in a concentrically fixed and stationary position of a compact cylindrical cap labelling device over the optical disc surface and therefore provides a method for affixing self adhesive labels onto optical discs with claimed superior results.
U.S. Pat. No. 5,951,819 describes an apparatus for applying labels on optical discs having a base capable of supporting a label, as well as a plunger element capable of supporting and positioning the optical disc with respect to the label. A means to equalize pressure is provided on the plunger element or the base to prevent pressure differentials.
However, there is still presently a need for a label applicator system and associated method that helps facilitate alignment of the label while improving application of pressure when applying the label on the disc.

DESCRIPTION OF PREFERRED EMBODIMENTS
Referring to any one of FIGS. 1 to 16, a label applicator system is disclosed.
The system is used for applying a disc-shaped label 10 as shown in FIG. 1, on a top surface of a disc. The system comprises an applicator base structure 12, shown in FIGS. 2 to 5. The base structure 12 comprises a disc support structure 14 and a handling tab support surface 16 attached to the disc support structure 14. The handling tab support surface 16 comprises at least one alignment post 18 extending vertically away from the handling tab support surface 16. The handling tab support surface 16 is generally in alignment with the top surface of the disc when the disc is inserted in the disc support structure 14.
As better shown in FIG. 1, the label 10 is produced from a label sheet 20. The label sheet 20 includes a top layer 22 having an upper surface and a lower surface. The lower surface is covered with a pressure sensitive adhesive glue. The label sheet 20 also includes a bottom layer having an upper surface detachably fixed to the lower surface of the top layer by means of the adhesive glue. The bottom layer is peelable from the lower surface of the top layer to allow fixation of the disc-shaped label 10 from the label sheet 20 onto the top surface of the disc. The top and bottom layers have tearing lines 26 punched therein. The bottom layer has a first cut 28. The top layer has a second cut 30 that is disc-shaped. All the tearing lines 26 and cuts 28,30 are made in such a manner and position as to leave a part of the bottom layer glued onto the bottom surface of the top layer in the form of a handling tab 32 when the disc-shaped label is peeled off from the label sheet. The top and bottom layers further have at least one perforation 34 formed within the handling tab 32. The at least one perforation 34 is sized and positioned so as to extend over the corresponding at least one alignment post 18 of the handling tab support surface 16 when the label is inserted on the applicator base structure for installation of the label on the disc. This allows an edge of the label opposite the handling tab to be applied to the disc and then allows a gradual application of a pressure to a remainder of the label through a movement extending from the edge towards the handling tab 32 which is peelable away from the label 10.
Preferably, the label sheet is made of paper. The label itself may be made of plastic or any other material known in the art.
Preferably, the upper surface of the bottom layer of the label sheet is covered with silicone.
Preferably, the label sheet also comprises a pair of case spine labels 36 made with a cut through a top layer of the label sheet.
Preferably, a single label sheet includes a pair of disc-shaped labels for installation on discs.
According to the present invention, as better shown in FIGS. 6A to 6J, there is also provided a method of applying a disc-shaped label to a top surface of a disc, the method comprising the steps of:
- a) providing an applicator base structure comprising:
- a disc support structure; and
- a handling tab support surface attached to the disc support structure and comprising at least one alignment post extending vertically away from the handling tab support surface, the handling tab support surface being generally in alignment with the top surface of the disc when the disc is inserted in the disc support structure;
- b) providing a label produced from a label sheet, the label sheet comprising:
- a top layer having an upper surface and a lower surface, the lower surface being covered with a pressure sensitive adhesive glue; and
- a bottom layer having an upper surface detachably fixed to the lower surface of the top layer by means of the adhesive glue, the bottom layer being peelable from the lower surface of the top layer to allow fixation of the disc-shaped label from the label sheet onto the top surface of the disc, the top and bottom layers having tearing lines punched therein, the bottom layer having a first cut, the top layer having a second cut that is disc-shaped, all the tearing lines and cuts made in such a manner and position as to leave a part of the bottom layer glued onto the bottom surface of the top layer in the form of a handling tab when the disc-shaped label is peeled off from the label sheet, the top and bottom layers further having at least one perforation formed within the handling tab, the at least one perforation being sized and positioned so as to extend over the corresponding at least one alignment post of the handling tab support surface when the label is inserted on the applicator base structure for installation of the label on the disc;
- c) tearing the handling tab away from the label sheet along the tearing lines, as shown in FIGS. 6A and 6B;
- d) peeling the label away from the label sheet using the handling tab, as shown in FIGS. 6C and 6D;
