Abstract
The lottery ticket is composed of base sheet (1), cover sheet (2) and ticket sheet (3) lying therebetween. Base sheet (1) and cover sheet (2) are adhered to each other in the edge region (6). The adhesive means is strip-shaped. In addition, base sheet (1) and cover sheet (2) are perforated to each other. Said perforation (9-12) is line-shaped and lies in said edge region (6) provided with glue. The distance of the perforation (9-12) from the edge (4, 5) of base and cover sheet (1, 2) is in the region of 2-4 mm. The ticket sheet (3) is thus completely surrounded by a border (6) of glue and by a border (9-12) of perforations lying therein. The six surfaces of base sheet (1), ticket sheet (3) and cover sheet (2) are provided with a plurality of imprints in base areas covering one another. Due to these imprints which cover one another and hence cross one another, the ticket sheet (3) cannot be deciphered by means of examining against the light when the lottery ticket is unopened. Due to the perforation (9-12) the border (6) of glue of the ticket sheet (3) cannot be penetrated by mechanical interventions without the edge of the lottery ticket being visibly damaged. Due to a glue which cannot be dissolved by various non-mechanical actions, the barrier of the border (6) of glue cannot be overcome.
Description




FIELD OF THE INVENTION




This invention relates to labels and structural features thereof and more particularly to labels having game pieces, coupons, or promotional materials therein and which retain their integrity notwithstanding immersion in liquid for extended periods.




BACKGROUND OF THE INVENTION




U.S. Pat. No. 4,846,504 to MacGregor, et al., incorporated herein in its entirety by this reference, discloses various “secure on-pack promotional coupons.” Such coupons include concealed promotional materials and may be secured to packaging of consumer products. In one embodiment of the assemblies described in the MacGregor, et al. patent, the coupons consist of a set or series of labels, each label formed of a base portion, an intermediate (promotional) portion, and an outer portion.




Repeatedly emphasized in the MacGregor, et al. patent is the requirement that the promotional coupon be




secured to a product by water soluble adhesive, so that the purchaser of the product must run water over the label or coupon in order to expose the coupon . . . and remove it from the product.




See MacGregor, col. 1, lines 56-60; see also id., col. 2, lines 20-23; col. 4, line 67 through col. 5, line 6. According to the MacGregor, et al. patent, this requirement purportedly deters “persons from removing or tampering with the labels prior to purchasing the products.” See id., col. 1, lines 63-65. It is, moreover, based on the assumption that water (or other liquid) is of only “limited availability . . . in stores.” See id., line 61.




While not necessarily erroneous, the assumption made in the MacGregor, et al. patent is inconsistent with certain present-day practices. For example, grocery and convenience stores (among others) now often include freestanding displays in which plastic beverage bottles are wholly or partially immersed in ice water. Conventional coolers and other containers similarly surround bottles with ice water in many cases. In each of these instances, promotional coupons of the type disclosed in the MacGregor, et al. patent may lose their integrity through immersion in or contact with water. As the water contacts the promotional coupons, the effectiveness of the water-soluble adhesive is diminished, resulting in premature separation of the outer portion from the remainder of the assembly and undesired exposure of the intermediate (promotional) portion.




Moreover, some types of plastic and other bottles are cleansed with hot water after all labelling is affixed. This cleansing is also likely to disturb the water-soluble adhesive used in the promotional coupons of the MacGregor, et al. patent and precipitate loss of integrity of the overall label assembly. Again, the result is premature separation of the outer portion and exposure of the promotional material.




Among initial attempts to solve this problem associated with water baths was utilizing a film to attach a paper game piece to a bottle. The larger film, to which adhesive was applied to the perimeter of its underside, effectively sandwiched the game piece against the outer surface of the bottle. Any defect in applying the film to the bottle permitted water to seep beneath the film into contact with the paper game piece, however, diminishing its viability as a solution to the problem.




SUMMARY OF THE INVENTION




By contrast, the present invention avoids problems associated with, among other things, these water baths by providing a multi-ply label structure in which a game piece is sealed from the ambient environment before affixation to a bottle. Because developed for purposes different than the promotional coupons of the MacGregor, et al. patent, moreover, the label structures of the present invention do not utilize water-soluble adhesive to attach components to a bottle. Instead, the innovative labels described herein are designed especially to retain their integrity notwithstanding immersion in either hot or cold water (or other liquid) for extended periods.




One embodiment of the invention includes four plies. In this embodiment the base ply may be a polypropylene or other liner whose underside is adherable to, among other things, a plastic bottle. Positioned atop the liner, and typically (although not necessarily) of lesser length and width, is a first polypropylene or similar film. The underside of the first film may in some cases be temporarily adhered to the upper surface of the liner, thereby forming a laminated structure.




Adhered to the base ply along the perimeter of its upper surface is a second polypropylene or other film. This second film constitutes the top of the multi-ply structure, and together with the base ply forms a pouch in whose central area a game piece, coupon, or other material may reside. The base ply and second films and the adhesive attaching them are selected so as to be water-impervious, thereby sealing the game piece from any water that might contact the label. Thus, neither immersion in water of a bottle containing such a label nor defective affixation of the label to the bottle is likely to destroy the integrity of the multi-ply assembly or the contents of the game piece contained therein.




As noted above, if desired the underside of the first film may contain adhesive to prevent the game piece from changing position within the pouch. The multi-ply assembly additionally may be manufactured on a backing tape or web for easy storage and transport in rolls. Such web, as is conventional, would have an upper surface coated with a release layer to facilitate removal of the assembly for affixing to a bottle. Because the game piece is protected from moisture while within the assembly, furthermore, it may include inks, scratch-off coverings, and other features that it otherwise could not successfully have. Moreover, because the first film may be part of the game piece, in some cases it may provide additional moisture resistance as well.




It is therefore an object of the present invention to provide a label structure that includes a game piece, coupon, or other promotional material.




It is another object of the present invention to provide a label structure which retains its integrity notwithstanding immersion in liquid for extended periods.




It is an additional object of the present invention to provide a label structure in which the game piece forming part of the assembly is sealed from the ambient environment before being affixed to, e.g., a bottle.




It is a further object of the present invention to provide a label structure avoiding use of a water-soluble adhesive to attach any portion of the structure to a bottle or other surface.




It is also an object of the present invention to provide a four-ply label including two layers of film and a base layer positioned intermediate the film layers and a substrate such as a bottle.




Other objects, features, and advantages of the present invention will become apparent with reference to the remainder of the text and the drawings of this application.

DETAILED DESCRIPTION




Illustrated in

FIGS. 1-2

is an exemplary label structure or assembly


10


of the present invention. The embodiment of assembly


10


shown in

FIGS. 1-2

may include four plies: base


14


, first layer


18


, game portion


22


, and second layer


26


. In use, these plies are effectively laminated to form the single assembly


10


which may be attached to a substrate such as bottle B.




Each of base


14


and second layer


26


may have the same length and width if necessary or desired. Equating dimensions of these components may enhance the aesthetic appeal of assembly


10


in some cases and promote protection of game portion


22


from the ambient environment. Base


14


and second layer


26


need not be dimensioned identically, however, nor need they be substantially rectangular as shown in

FIGS. 1-2

. Instead, those skilled in the art will recognize that these components may have different dimensions and shapes than those expressly illustrated herein.




Generally, however, the length and width of game portion


22


and first layer


18


will be less than those of base


14


and second layer


26


. This permits base


14


and second layer


26


to encapsulate game portion


22


when their respective peripheries


30


and


34


are adhered. As so encapsulated, game portion


22


is sealed in a pouch formed between central areas


38


and


42


of base


14


and second layer


26


, respectively.




Certain embodiments of assembly


10


are designed to include clear polypropylene film (which may be one mil thick) as both first and second layers


18


and


26


. Because such film is impervious to water, sealing game portion


22


underneath second layer


26


helps prevent any substantial seepage of moisture into the pouch containing portion


22


. Thus, game portion


22


is not typically subjected to the detrimental effects of moisture even should it be bathed or immersed in water for an extended period of time. This avoidance permits game portion


22


to have numerous features (such as inks, scratch-off materials, etc.) to enhance its promotional or entertainment abilities that otherwise could not be present if subject to contact with moisture. When present, first layer


18


may be adhered to game portion


22


using water-based or other adhesive


43


to form game piece


44


. In such cases, the water-impervious nature of first layer


18


may further assist in protecting portion


22


from moisture.




Base


14


may, if desired, be a layer of greater thickness than layers


18


and


26


. In addition to helping seal game portion


22


from moisture, base


14


functions to attach the remainder of assembly


10


to bottle B or another substrate. It thus must be sufficiently thin and flexible to accommodate and conform to the contoured surface S of bottle B yet sufficiently strong to maintain its structural integrity when subjected to automatic affixation techniques, temperature extremes, and moisture. A presently-preferred material for base


14


is a 2.9 mil thick white polypropylene film with a #40 liner, which also has sufficient opacity to prevent someone from visually discerning the contents of game portion


22


by peering through whatever liquid is contained within bottle B. Because a consumer need not remove base


14


from the bottle B to access game portion


22


, base


14


may be attached to the bottle B using a substantially permanent pressure-sensitive or other adhesive


46


placed on its underside


50


.




By contrast, first layer


18


is typically removed from bottle B as part of game piece


44


. Any suitable adhesive


54


, including one cured using ultraviolet radiation (a “UV adhesive”), may thus be applied either to upper surface


58


of base


14


or underside


62


of layer


18


(or both) to adhere the two together. Depending on the material chosen for base


14


and game portion


22


, in some situations first layer


18


may be omitted.




Placed atop adhesive


54


and upper surface


58


(in central area


38


) is game piece


44


. If completely or substantially opaque, game portion


22


of piece


44


may include text, symbols, or other information on its underside


70


that is obscured from view on the one hand by its upper surface


74


and on the other by base


14


. Similarly, because game portion


22


obscures central area


38


of upper surface


58


from view, hidden textual or other information may be printed or otherwise included thereon as well. As noted above, scratch-off or other material, including any or all of the elements of the cards disclosed in U.S. Pat. Nos. 5,569,512 to Brawner, et al. and U.S. Pat. No. 5,601,887 to Rich, et al. (incorporated herein in their entireties by this reference), may be included on either or both of underside


70


or upper surface


74


of game portion


22


.




To encapsule game piece


44


, adhesive


78


is applied to either or both of peripheries


30


and


34


to bond them together. Doing so effectively forms a pouch between central areas


38


and


42


in which game piece


44


resides. If necessary or appropriate to prevent piece


44


from moving within the pouch, adhesive


54


may be used to attach underside


62


to upper surface


58


. Adhesives


78


and


54


may, in the vernacular of the MacGregor, et al. patent, be “removable” or otherwise temporary bonding agents, as they usually should not prevent a consumer from removing game piece


44


from the remainder of assembly


10


.




To access piece


44


, in most cases the consumer need merely peel second film


26


away from the remainder of the assembly


10


. Facilitating such removal may be information printed on upper surface


58


of base


14


such as the phrase “pull here” and an arrow pointing to a corner of assembly


10


. Removing second film


26


exposes upper surface


74


of game portion


22


. If (temporary) adhesive


54


is present, a consumer may merely peel composite game piece


44


away from upper surface


58


of base


14


to expose underside


62


and remove the piece


44


from the remainder of assembly


10


. Those skilled in the art will recognize that game piece


44


is not limited to two-sided structures, but may instead contain folds, cut-outs, or pop-ups, for example, or otherwise be more complex than a simple two-sided material. Alternatively, in some cases piece


44


need not include first layer


18


and adhesive


43


.




The foregoing is provided for purposes of illustrating, explaining, and describing embodiments of the present invention. Further modifications and adaptation to these embodiments will be apparent to those skilled in the art and may be made without departing from the scope of spirit of the invention.
