DETAILED DESCRIPTION OF THE INVENTION

(12) Described herein are labels that are suitable for use in a cold environment, such as the refrigerated and frozen food departments of a store, and methods of making the same. Such labels are similar to traditional labels in terms of the paper, laminate and certain aspects of the manufacturing process but, in place of a pressure sensitive adhesive tape used to secure the label to the shelf, a plastic substrate to which adhesive has been affixed is secured to the paper tag, in exemplary embodiments. New processes are required to automate the process of coupling the plastic substrate to the paper tag, as described more fully herein.

(13) FIG. 1 is a side and exploded view of a composite substrate 1000 comprising a paper substrate layer 100 and a plastic substrate layer 10, in accordance with an exemplary embodiment of the present invention. Paper substrate layer 100, in certain exemplary embodiments, comprises a printed display information sheet 80, which includes display information printed thereon (e.g., bar codes, prices, unit prices, sale information, advertisements), a first layer of lamination material 82 and a second layer of lamination material 81. Plastic substrate layer 10, in certain exemplary embodiments, comprises an adhesive strip 15 and a plastic substrate 20. Paper substrate layer 100 is formed of a first material (e.g., paper which, in one embodiment, is laminated on the top and bottom) and plastic substrate layer 10 is formed of a second material (e.g., plastic). The second material is stiffer than the first material. The second material may be supplied in a roll form for coupling to the first material. In some embodiments, paper substrate layer 100 is not formed from paper laminated on the top and bottom. For example, in other embodiments, paper substrate layer 100 is formed from paper alone (no laminate) or from a vinyl material (or poly, foil etc.) with display information printed on the vinyl material.

(14) FIG. 2A is a perspective view of the plastic substrate layer 10 in accordance with an exemplary embodiment of the present invention. Plastic substrate layer 10 includes plastic substrate 20 with adhesive strip 15 affixed to the top. Adhesive strip 15 is used to couple plastic substrate 20 to paper substrate layer 100. In the exemplary embodiment, adhesive strip 15 is adhered to the bottom side of plastic substrate layer 10, e.g., first layer of lamination material 82. Plastic substrate layer 10 is associated with a width W.sub.1. W.sub.1 is in the range of 0.0007 to 0.001 inches, in an exemplary embodiment. The plastic substrate 20 is associated with a height H.sub.1 and the adhesive strip 15 is associated with a height H.sub.2. H.sub.1 is, in an exemplary embodiment, about 1¼ inches. H.sub.2 is, in an exemplary embodiment, ½ to ⅝ inches. The adhesive strip 15 is substantially centered within the height of the plastic substrate H.sub.1, in an exemplary embodiment.

(15) FIG. 2B is a perspective view of the paper substrate layer 100. Paper substrate layer 100 is associated with a width W.sub.2.

(16) While in the illustrated embodiment plastic substrate layer 10 is coupled to the underside of paper substrate layer 100 using adhesive strip 15, other methods of coupling plastic substrate layer 10 to paper substrate layer 100 are possible.

(17) FIG. 4A is a top view of the composite substrate 1000 in accordance with an exemplary embodiment of the present invention. Composite substrate 1000 includes at least two rows and at least two columns and includes a top edge 110, a bottom edge 120, left edge 140 and right edge 130. Composite substrate 1000 comprises a plurality of individual display information tags 50 arranged in an array of rows R and columns C. The individual display information tags 50 are formed from composite substrate 1000 by lines of perforations 68 cut along the rows and lines of perforations 60 and 61 cut along the columns, as described in more detail with reference to FIGS. 4B and 5B. Each display information tag 50 is associated with a height H.sub.3 and length L.sub.1. In an exemplary embodiment, L.sub.1 is approximately 1 inch to 1¼ inch. Each column is associated with a height H.sub.4 and a length, the length of the column coinciding with the length of a single display information tag 50, L.sub.1. Each row is associated with a length L.sub.2, which is the length of composite substrate 1000, and a height, which is the height of a single display information tag H.sub.3. In production, composite substrate 1000, in some embodiments, is cut from a larger sheet of composite material (i.e., knife cuts in the larger sheet of material result in clean edges, namely top edge 110, bottom edge 120, left edge 140 and rights edge 130). A top edge of plastic substrate layer 10 is generally co-extensive with top edge 110.

(18) FIG. 3 is a top view of an individual display information tag 50 in accordance with an exemplary embodiment of the present invention. Display information tag 50 includes a first portion 51 and a second portion 52. First portion 51 and second portion 52 may be separated by a line of perforations 63, in some embodiments. As shown in FIG. 4A, each row of composite substrate 100 may include a line of perforations 63a and 63b. In other embodiments, there is no physical indication of separation (e.g., no line of perforations 63) between first portion 51 and second portion 52. Each display information tag 50 may include printed indicia (e.g., printed on printed display information sheet 80), including a bar code, price, unit price, advertisements or sale information. In exemplary embodiments, the bar code, price and unit price is contained within first portion 51 and advertisements and sale information is contained within second portion 52. However, other configurations are within the scope of the present invention.

(19) FIG. 4B is an enlarged view of a portion of FIG. 4A which illustrates the perforations 60a and 60b and 61a and 61b cut between adjacent columns of composite substrate 1000. Perforations 60a and 60b are cut through the width of composite substrate (i.e., W.sub.1+W.sub.2) between adjacent columns of composite substrate 1000 in the sections that include plastic substrate layer 10. Perforations 61a and 61b . . . . 61n are cut through the width of composite substrate (i.e., W.sub.2) between adjacent columns in the sections that do not include plastic substrate layer 10. Between perforations, ties 62a, 62b and 62c remain in the sections of composite substrate 1000 that include plastic substrate layer 10 (as well in the portion of composite substrate 1000 that does not include plastic substrate layer 10 between perforations 61a, 61b . . . . 61n, although the ties between perforations 61a, 61b . . . . 61n are not labeled in FIG. 4A or 4B), to hold composite substrate 1000 together prior to manual separation. In order to separate composite substrate 1000 into display information tags 50, it is necessary to manually separate composite substrate 1000 at perforations 60a, 60b, 61a, 61b . . . 61n, as well as along perforation line 68. In certain exemplary embodiments, a height of each of perforations 60a and 60b (H.sub.P1) is approximately 0.5650 inches; a height of each of perforations 61a, 61b . . . 61n (H.sub.P2) is approximately 0.040 inches; and a height (H.sub.T) of each of ties 62a, 62b, 62c is approximately 0.40 inches, or may be 0.02 inches in certain embodiments.

(20) In some embodiments, in order to achieve the perforations, there could be a full cut in the plastic material and perforations in the paper portion (referred to as a slit over perf). Perforations 60a and 60b can be full or solid cuts. Ties 62a, 62b and 62c may be included in the cuts of section plastic substrate layer 10 for strength of the composite substrate 1000 for manufacturing and delivery purposes.

(21) FIG. 5A is a bottom view of the composite substrate 1000. In this view, plastic substrate layer 10 is visible, having been coupled to the underside of paper substrate layer 100. In some embodiments, there is a small gap (e.g., 1/16 inches; gap not shown in FIG. 5A) between the top edge 110 of the paper substrate layer 100 and the top edge of the plastic substrate layer 10. Perforation 68 is included in the paper substrate layer 100 for purposes of separating of the individual labels 50.

(22) FIG. 5B is an enlarged view of a portion of FIG. 5A and is similar to FIG. 4B except that plastic substrate layer 10 is visible and, as described above, in some embodiments, a small portion (e.g., 1/16 inches of paper substrate layer 100) extends above plastic substrate layer 10, though this portion/gap is not shown.

(23) FIG. 6 is a side view of a display information tag 50 clipped into a shelf edge 5, in accordance with an exemplary embodiment of the present invention. First portion 51 of display information tag 50 may be contained within the area of the shelf edge and second portion 52 of display information tag 50 hangs down from the shelf edge. Plastic substrate layer 10 may clip into the top flange 7 and bottom flange 8 of the shelf edge.
