DETAILED DECRIPTION OF THE INVENTION

In the embodiments described herein in Figures the common elements are identified with the same numbers.

FIGS. 1(A), 1(B) and 1(C) show a lid 20 and resealable tab 22 for a drinking cup. Each tab may be of a different shape or may be the same shape but of different size. Advertising indicia may be included on or affixed to the tab 22. The lid 20 has a outer edge 26 having a generally circular periphery and a top surface 30 for defining a drinking opening, visible as element 32 in FIG. 3, and having a predetermined shape and dimension.

An annular sidewall 40 is operatively connected to and extends circumferentially or axially from the outer edge 26 and extends in a first direction relative to the top surface. In FIGS. 1(A), 1(B) and 1(C), sidewall 40 extends away from the top surface 30. Sidewall 40 extends higher around about halfway of the periphery of the lid 20,

An annular mounting member 42 is formed on the lid 20 and functions to sealingly engaging the lip of a drinking cup 46. In FIGS. 2(A), 2(B0 and 2 (C), the annular mounting member 42 extends circumferentially or axially around the edge of the cup 46. The resealable tab 22 folds over the top surface 44 defined by the annular sidewall 40 to insure a sealing relationship.

The resealable tab 22 has a relatively thin, flexible substrate having a first surface and second surface as shown in greater detail in FIGS. 6(A), 6(B), 6 (C), 7(A), 7(B) and 7 (C). The substrate has a predetermined shape and dimension which is adapted to cover the drinking opening 32 with either one of of the first and second surfaces.

In FIGS. 1(A), 1(B), 1(C), 2(A), 2(B), 2(C), 3(A), 3(B) and 3(C), the annular sidewall 40 extends in first direction which is away from the top surface 30 defining the drinking opening 32.

In FIGS. 3(A), 3(B) and 3(C) depicts the tab 22 as being removed from the opening 32 and being temporarily stored on top surface 30.

In FIG. 4, the annular sidewall 40 on the outside extends in a first direction which is away from top surface 30 defining the drinking opening shown by dashed opening 32′. The partially recessed area shown by arrow 62 communicates with a sloped surface 59 which extends in a direction which is towards the recessed area 62 and top surface 30.

In FIG. 5 the embodiment of the lid 63 is generally circular shaped and has a raised outer annular ring 64 having sidewalls 66. The center portion adjacent the sidewalls 66 forms a recessed area within the central lid surface and is recessed over substantially the entire surface as shown by recessed area 65. The recessed area 65 is adapted to receive the lip of a user. A resealable tab 68 is located across the drinking opening shown by dashed opening 32″ formed in the top surface 67 of the annular ring 64. The drinking opening 32″ is located under the resealable tab 68.

In FIGS. 6(A), 6(B) and 6(C), a resealable tab 70 for a drinking cup lid surface 80 has a food grade adhesive 72 coated on one of the first surface 74 and second surface 76. The adhesive 72 forms a sealing layer having a predetermined thickness. As shown in FIG. 6(C), the one of the first surface and second surface is affixed in an opposed spaced relationship to the drinking opening 32. The spacing there between is determined by the thickness of the adhesive sealing layer. In FIG. 6(C), surface 76 has the adhesive 72 coated or formed thereon forming an adhesive sealing layer.

As shown in FIGS. 6(A), 6(B) 6(C), 7(A), 7(B) and 7(C), a food grade adhesive is located between one of the first surface and second surface and a drinking cup lid surface 80 or 100 to enable one of the first and second surfaces to be located over the drinking opening 32. The adhesive is shown as 72 in FIG. 6(C) and as 86 in FIG. 7(C) and forms a sealing relationship between that portion of the top surface 30 defining the drinking opening 32. In FIGS. 6(A), 6(B) and 6(C), the one of the first surface and second surface exposes the remaining portion of the adhesive to the drinking opening 32 located in the top surface. The spacing between 72 and drinking cup lid surface 80 is determined by the thickness of the adhesive sealing layer as depicted in FIGS. 6(C) and 9(C).

In FIG. 6(C), the drinking cup lid surface 80 is in sealing engagement with the adhesive 72 which is preferably coated on surface 76.

It is envisioned that any technique for applying the adhesive may br used in practicing this invention. This includes, without limitation, spraying, coating, vaporizing, sputtering, rolling, affixing preshaped adhesive forms around the opening on the tab surface and any other technique known to persons skilled in art.

The food grade adhesive may comprise a polyethylene composition or other food grade adhesive as is well known in the art. For example labels affixed to fruit and vegetables have food grade adhesive.

Preferably, the food grade adhesive comprises a composition which has increased adhesivity as the temperature thereof is increased above ambient temperature. Such an adhesive would provide a better sealant for hot liquids, such as hot coffee in a drinking cup.

It is envisioned that a combination for protecting the invention would comprise the following elements: (i) a drinking cup having a lip defining a top opening, and (ii) a lid having an outer edge having a generally circular periphery. In such a combination, the lid includes a top surface for defining a drinking opening having a predetermined shape and dimension and an annular shaped sidewall which is operatively connected to and which extends circumferentially or axially from the lid and in a first direction relative to the top surface. An annular mounting member is formed on the lid for sealingly engaging the lip of the drinking cup.

A resealable tab for use in the combination would have a relatively thin, flexible substrate having a first surface and second surface wherein the substrate would have a shape and dimension which is adapted to cover the drinking opening with either one of the first surface and second surface. A food grade adhesive is located between one of the first surface and second surface and the top surface to enable one of the first and second surfaces to be located over the drinking opening and to have the adhesive form a sealing relationship between that portion of the top surface defining the drinking opening and the one of the first and second surface, the spacing there between being defined by the thickness of the adhesive layer.

Thus, FIGS. 6(A), 6(B) and 6 (C) covers the preferred embodiment wherein the adhesive 72 is coated on the second surface 76. The second surface 76 having the adhesive 72 located thereon is affixed to the drinking opening 32 exposing that portion of the adhesive not in sealing engagement with surface to the drinking opening 32 to fluid spouting through the sealed drinking opening 32 and into contacting the adhesive 72.

In the alternative, FIGS. 7(A), 7(B) and 7(C) cover the embodiment wherein the adhesive 86 is coated on the top surface of a drinking cup lid surface 100 and no adhesive is affixed to the resealable tab 80. One of the first surface 82 and second surface 84 is affixed to the adhesive 86 coated on that portion of the top surface of a drinking cup 100 surrounding the drinking opening 32. This embodiment reduces the amount of adhesive which would come in contact with a fluid spouting through the sealed drinking opening 32.

In FIG. 8, the pictorial representation of an oblong shaped substrate or tab 102 is shown as having a lifting member 103. The tab 102 may be used for a drinking opening which can be either oblong or oval in shape. Such shapes of drinking openings are disclosed in the known prior art lids for drinking cups as described above. Dashed lines 103 represent a protruding lifting member to facilitate removal an/or replacement of the tab 102 on a drinking opening.

The lifting member can be formed of any predetermined shape, such as for example, a protruding lifting member or an elongated lifting member.

In FIG. 9, the pictorial representation is of a circular shaped substrate 104 adapted for use for removeably sealing a drinking opening having a dimension which is less than that of the circular shaped substrate. The dimension of the circular shaped substrate should be selected to allow sufficient overlap of the edge thereof beyond the periphery of the drinking opening. Dashed lines 105 represent a protruding lifting member to facilitate removal and/or replacement of the tab 104 on a drinking opening.

In FIG. 10, the pictorial representation is of an elongated shaped substrate or tab 106 adapted for use as a resealable tab for practicing this invention Thus, if the shape of the tab is oblong or oval, no lifting member may be required.

In FIG. 11, the pictorial representation is of a rectangular shaped substrate or tab 108 adapted for use as a resealable tab for practicing this invention. Tab 108 has an appropriate predetermined shape and dimension which can be sealed using a rectangular shaped resealable tab.

In FIG. 12, the pictorial representation is of a resealable tab 110 which is a combination of a circular shape and rectangular shape configured for use as a resealable tab for practicing this invention in a manner similar to that described above in connection with FIGS. 8 thorough 11.

In FIG. 13, the pictorial representation is of an oblong shaped substrate or tab 112 similar to tab 106 illustrated in FIG. 10, except that 112 has a protruding lifting member 114 adapted for use as a resealable tab for practicing this invention. A user can use a user's fingers to grasp the protruding lifting member for removing the resealable seal from the drinking opening. Also, a user can utilize the protruding lifting member to reaffix the resealable tab over the drinking opening.

FIG. 14 is a chart, which illustrates by shape, several examples of resealable tabs and associated lifting members for a selected number of tab sizes, in mm plotted or shown as a function of tab depth, in mm. In the chart of FIG. 14, a resealable tab having a size of 20 mm and tab depth of 14 mm is shown to have and oval shape 202 having a lifting member 204. Tab shape 206 has a lifting tab 208, a size of 23 mm and depth of 14 mm. Tab shape 210 has a tab size of 26 mm, a tab depth of 14 mm and lifting member 212. Tab shape 214 has a size of 29 mm and depth of 14 mm and a lifting member of 216. If the label depth Is held at about 14 mm and the tab size is increased, the resealable tab takes on a more generally oval or oblong shape.

Resealable tab shapes 302 through 314 are illustrated for tab sizes 20 mm, 23 mm, 26 mm and 29 mm. Each of the tab shapes 302, 306, 310 and 314 have lifting members 304, 308, 213 and 316 respectively.

Tab shapes 402, 406, 410 and 414 are illustrated using the same tab depth of 22 mm, and vary in tab sizes of 20 mm, 23 mm, 26 mm and 29 mm respectively. Each tab shapes 402, 406, 410 and 414 have lifting members 404, 408, 412, and 416 respectively. Lifting member 408 is depicted as being formed of a selected shape in the tab 406. Lifting members 404, 408, 412 and 416 are shown by dashed lines and can be formed in any appropriate shape.

Resealable tab shapes having a 25 mm depth and tab size of 20 mm, 23 mm, 26, and 29 mm are shown by tab shapes 502, 506, 510 and 514 having lifting tabs 504, 508, 512, and 516 respectively.

As shown as tab shapes 502, 506, 510 and 514, as the tab depth is increased and the tab size approach the tab depth, the resealable tab is generally annular or circular shape.

However, when the tab depth is increased to 30 mm, the tab shapes shown 602, 606, 610 and 614 are more oval shaped at tab sizes 20 mm and 23 mm, but become more annular shaped as shown by tab shapes 610 and 612. Resealable tab 614 is generally circular shaped. Each of the tab shapes 602, 606, 610 and 614 have a lifting member depicted in dashed members 604, 608, 612 and 616, respectively. As depicted in lifting member 604, the lifting tab can extend to be a significantly extended protruding lifting member. In the alternative, the lifting member can be a thin elongated member as depicted by lifting tab 616.

It is envisioned that the teaching of this invention could be used for a lid to be applied to a container, for any beverage, liquid or the lid where the lid has an orifice, opening or aperture that could be used as an access opening, pouring opening, drinking opening, straw passage opening or the like when the lid is operatively attached to a container. The orifice, opening or aperture in the lid can be resealed using the resealable tab of the present invention.

The fluid, beverage or the like placed in a container having a lid and drinking opening closed or sealed using the resealable tab of the present invention may be hot or cold fluid or liquid. It is envisioned that a variety or known food grade adhesives could be used in practicing this invention depending on the application.

The thickness of the adhesive layer may preferably be selected to vary from about 0.001 inch to about 0.010 inch. In certain applications where a strong bonding is required, the thickness may be greater than about 0.010 inch. In certain applications the thickness may be less than about 0.001 inch depending on the requirements, such as dimension and shape of the opening. The adhesive layer must be of a sufficient or minimum thickness to not be opened or unsealed by the force of the fluid spouting through the sealed opening. If the adhesive layer is too thick, the tab may be to high off of the drinking opening, which is undesirable.

Also, if a more aggressive adhesive is required, the surface area of the adhesive seeking area can be increased. Generally, this would require the use of the tab having a greater surface area for engaging and sealing with the top surface.

It is envisioned that all variations of the resealable tab shapes, size, adhesives, thickness of the adhesive sealing layer and opening size can be accommodated using the teachings of this invention.
