TECHNICAL FIELD
This disclosure relates to lids for drinking cups, and more specifically, to lids for containers for beverages, and in some aspects, to containers for beverages having an aroma, such as coffee or tea.
BACKGROUND
Disposable beverage containers—which may be described herein as drinking cups or beverage cups—are ubiquitous for use in “on-the-go” consumption of liquids, particularly hot beverages such as coffee or tea. Disposable beverage cups often utilize a disposable lid to minimize splashing or spilling of the beverage from the container. Disposable lids most commonly used at this time provide a horizontally oriented drink opening on a top surface of a raised rim. Many of such designs allow a user to drink through the lid in a manner similar in many respects to drinking through a straw, or worse, in that it seems a limited amount of liquid is provided. Such shortcomings are exacerbated when vent openings are minimal or otherwise inadequately provided. Moreover, since such a drink opening is covered by the lips of the user while drinking, very little aroma from the beverage escapes to the user's nose.
Prior efforts to develop a disposable lid that would enable a user to drink naturally, as if drinking out of a cup or mug that does not have a lid thereon, have resulted in various undesired effects that have limited their utility. Thus, there remains a need to provide a lid design for a disposable beverage cup or container that is easy to use. It would be even more advantageous for such a lid to be provided in a disposable material. In would be additionally desirable if such a lid design were available that significantly enhances pleasurable drinking experience, in the manner of presentation of liquid to the user, and/or in the manner of providing aroma of the beverage to the user.
SUMMARY
A novel drink-through type beverage container lid has been developed, that in various embodiments, significantly enhance the pleasure of a user's beverage drinking experience as compared to various prior art lids and containers. The lid provides a drink outlet that allows liquid to fill a drink well base, and from which a consumer may sip a beverage similar to using a cup or mug. The lid has a base with a rim having a bottom edge, and an interior bead sealing portion. In an embodiment, the rim may be annular in shape. The base is sized and shaped to sealingly engage, via the interior bead sealing portion, an open end of a beverage cup. In many embodiments, a circular opening is provided in a beverage cup, which may be defined by a bead at the upper reaches thereof, and in such cases, the interior bead sealing portion sealingly engages the bead on the beverage cup. In an embodiment, when the drink-through lid is in use on a beverage container, the interior bead sealing portion may be centered with respect to a bead on the beverage cup. A hollow raised lip portion is provided in the lid, and it has an exterior portion extending upwardly from the base, an outer lip portion, and an interior portion sloping downwardly from the outer lip portion to lower end portions. In an embodiment, the interior portion of the raised hollow lip portion may slope inwardly from the outer lip portion.
A drink well base for containing liquid is provided. In an embodiment, the drink well base has a sloped floor extending upwardly from a peripheral side along the lower end portions. In an embodiment, the drink well base may be located above the bottom edge of the rim and below the outer lip portion. In an embodiment, the lowest portion of the floor of the drink well base may be located, vertically, above the center line of the interior bead sealing portion. In an embodiment, the lowest portion of the floor of the drink well base may be located at or near the vertical level of the center line of the interior bead sealing portion. In an embodiment, the lowest portion of the floor of the drink well base may be located below the center line of the interior bead sealing portion. In various embodiments, the drink well base may be located vertically at a level that is at about one-half inch (0.5′′) (1.27 cm) below the center line of the interior bead sealing portion, or higher. At least one drink outlet is provided. The at least one drink outlet may be defined by a first edgewall extending upward into the interior portion of the hollow raised lip portion, and by an elongated second edgewall extending along an outlet portion of the drink well base in proximity to the peripheral edge. In an embodiment, a portion of the at least one drink outlet may be oriented along a first surface extending from the elongated second edgewall at an angle alpha (α) in the range of from about forty degrees)(40° to about ninety degrees)(90°. In an embodiment, the first surface may be a planar surface. In an embodiment, a portion of the at least one drink outlet may be oriented along a second surface extending along the drink well base. In an embodiment, the second surface may be a planar surface. In an embodiment, the drink opening may be defined as if the first surface and the second surface are joined along a radiused curve. In an embodiment, a first planar surface and a second planar surface may be joined as if along a radiused curve. In an embodiment, an inwardly protruding shoulder may be provided from the interior portion of the hollow raised lip portion, and the drink opening may be defined by an opening cut along the inwardly protruding shoulder. In an embodiment, the inwardly protruding shoulder may be arcuate in shape, with an upwardly directed arching central portion.

In an embodiment, as also seen in FIG. 14, the baffle 150 may include a lower end 170. The lower end may include an upwardly extending lower baffle wall 172. The lower baffle wall 172 may define, in combination with beverage container 32, a liquid passageway 174 above bottom 176 of beverage container 32, as seen in FIGS. 10, 12, and 14.
As seen in FIGS. 7 and 14, the beverage container 32 may include an inner sidewalls 180 that are generally frusto-conical in shape, and in such an embodiment, the baffle may include a first side 184 and a second side 186 that are complementary in shape with the beverage container inner sidewalls 180. In an embodiment, first side 184 and second side 186 of baffle 150 are shaped and sized for sealing engagement with the beverage container inner sidewalls 180.
The baffle 150 divides the beverage container 32 into at least a first chamber C1 and a second chamber C2, and in such a configuration, the baffle 150 is shaped and positioned to allow liquid 36 in the beverage container to flow freely between each of the chambers C1 and C2, using liquid passageway 174, as seen in FIG. 10 at reference arrows 188 and 189. The baffle is effectively sealed with the drink-through lid at said slit 140, and positioned to prevent vapor V1 within the first chamber C1 that is between the drink-through lid 130 and liquid 36 in the beverage container 32 from flowing to the second chamber C2. In this manner, associated with each of the chambers C1 and C2, is at least one vapor-directing passageway(s) 112 and/or at least one vapor passageway(s) 122. Further, vapor-directing passageways 112 and/or vapor passageways 122 are disposed in the lid 30 on either side of the baffle 150. Thus, when the beverage container 32 contains liquid 36 and is tipped (see FIG. 11) to allow liquid to flow out of the drink outlet 34, as indicated by reference arrow 182, vapor V1 within the first chamber C1 is forced out of one or more of the at least one vapor passageways 122 as indicated by reference arrow 190, while air outside of the beverage container is simultaneously drawn into the second chamber C2 through one or more of the at least one vapor-directing passageways 112 as indicated by reference arrow 192. Likewise, when the beverage container 32 is tipped down, after drinking is completed, as shown in FIG. 12, vapor V2 exits the second chamber C2 through one or more of the vapor-directing passageways 112, as indicated by reference arrow 194. As liquid 36 retreats in the first chamber C1, outside air passes through vapor passageway(s) 122 to replenish the vapor V1 within the first chamber C1, as indicated by reference arrow 196. In various embodiments, the at least one vapor passageways 122 may be oriented to project vapors initially in a direction that is predominantly horizontal in relation a plane along a centerline 82′ of said interior bead sealing portion 50.
In various embodiments, either or both of the lid 30 or baffle 150 may be made from thermoplastic material. In an embodiment, such thermoplastic material may be suitable for vacuum forming of the lid 30. In an embodiment, baffle 150 may be provided in a selected composition of paper or paperboard.
In various embodiments as disclosed herein, a drink-through lid (30, or 130) design is disclosed herein that provides a drinking experience to a user much the same as if the user were drinking from an open container such as a coffee cup, rather than using various prior art disposable drink-through lids for drinking cups. Improved user interface is accomplished by selecting the size and shape of the drink outlet 34, in combination with providing a suitable size and shape of the drink well base 40 floor 63 shape, so that when a beverage cup 32 is tipped in normal drinking fashion, the liquid gently hits the user's lips, thus providing a “soft” feel to the user.
In one aspect, a design is provided that when used for drinking provides a wide, relatively slow moving liquid surface when the liquid approaches the user's lips. In an embodiment, this is accomplished by providing a liquid outlet that provides a “fountain” effect caused by the vector of the liquid emerging from the drink outlet. The “fountain” effect is powered by the head pressure created when the liquid inside the container is at a higher elevation than the drink outlet. Because the height of the liquid is determined by angle that the beverage cup 32 is tilted, the more that the beverage cup is tilted, the higher the height of the liquid as compared to the drink outlet, and thus, the more hydraulic head. Of course, the rate of change of head pressure and the duration that the head pressure is at a particular point determines how fast the drink well floor fills with liquid. The fountain effect is largely determined by the location, orientation, and sizing of the drink outlet 34, which determines the origin and direction of the fill vector in relation to the user's lip, and the time required for drink well filling. With respect the size of the drink outlet 34, in an embodiment, the origin and direction of the fill vector provides an emerging liquid fountain that is predominantly vertical when the beverage cup 32 is in a tipped, drinking orientation. Thus, the size of the drink outlet 34 determines how far the liquid fountain projects when the beverage cup 32 is tipped by a user for drinking.
With respect to proper sizing of a drink outlet 34, if the drink outlet 34 opening itself is too small, the drink well base 40 does not fill fast enough, which may result in the user overtipping the beverage cup 32. Too small of a drink outlet 34 may also result in a liquid fountain that is too high, in that such a “fountain” may shoot up and hit the user's lip in an unsatisfying way. Too large of a drink outlet 34 can sacrifice the splash and spill protection provided by the lid 30. The key is to provide a drink opening 34 which is large enough so that, given the tip rate of a beverage cup 32 by a user, (a) results in the filling of a drink well base 40 to the point that liquid reaches the user's lip fast enough so that the user does not “over tip” and create excessive head pressure, and (b) results in the filling of the drink well base 40 with a liquid having a surface that is relatively calm—flat rather than turbulent—when the liquid reaches the user's lip. Thus, when the beverage cup 32 is tipped, the vertical component of the liquid fountain provides liquid that quickly emerges, but then spreads out promptly in the drink well base 40, so that as the drink well base 40 fills, the leading edge of liquid—that is the edge closest to the user's lips, spreads out widely and slowly toward a user's lip.
Further, it has been found that selecting an optimum shape for the drink well base 40, and the interaction of the drink well base 40 with the drink outlet 34, may also provide benefits to enhance the drinking experience of a user. For purposes of example only, and not by way of limitation, in an embodiment it has been found that a suitable shape for a drink well base 40 may be provided as a generally wedge shaped volume, structured for example in much the same shape as a segment of a small orange (or similar fruit) laid out so that the center of the segment is across the lid, and one side of the segment is horizontal, and the other size extends angularly downward from the center of the segment toward the bottom of the drink outlet to provide an arcuate side shape approximating the interior portion 62 shape of a raised hollow lip portion 54 of the drink-through lid 30. Such shape can be easily envisioned in FIG. 22, where liquid 99 is shown along the interior portion 62 of the hollow raised lip portion 54. In contrast to many prior art patents which have just a lower tangent edge of a drink outlet (such as of a circle or of an ovoid shape at the lower reaches of a drink well), experimentation during development of the drink-through lid 30 or 130 as disclosed herein reveals that better drinking experience results are achieved if at least a portion of an elongated bottom, i.e. an elongated second edgewall 76, of a drink outlet 34 is provided along the lower reaches of the drink well base 40, rather than merely as a tangent portion, as provided in certain prior art patents.
Attention is directed to FIGS. 18, 19, and 20, wherein different embodiments for the shape and size of a drink well base are provided. In FIG. 18, a drink well base 40 is provided having a peripheral side 64 that ends at a vertical level at or about the centerline 82′ of the interior bead sealing portion 50, and a drink outlet 34 is provided. In an embodiment the centerline 82′ may be parallel to a plane 82 defined by the bottom edge of an annular flanged rim 46. In FIG. 19, a drink well base 40′ is provided having a peripheral side 64′ that ends at a vertical level well below the centerline 82′ of the interior bead sealing portion 50, and a drink outlet 34′ is provided. In such an embodiment, the peripheral side 64′ of the drink well base 40′ should be no further than zero point five (0.5) inches (1.27 cm) below the centerline 82′ of the interior bead sealing portion 50. In FIG. 20, a drink well base 40′′ is provided having a peripheral side 64′′ that ends at a vertical level above the centerline 82′ of the interior bead sealing portion 50, and a drink outlet 34′′ is provided.
Additionally, it may be noted that the volume of liquid necessary to fill the “wedge” shaped space in the drink well 40 below the user's lip may vary as the amount of liquid in the beverage cup varies. In various embodiments, a drink well may be sized and shaped to allow sufficient liquid to be contained therein so that the user can take satisfying slurps or drinks of different sizes.
As may be seen by reference to FIG. 21, in order to provide the above described advantages in a thermoformed drink-through lid, an embodiment has been developed in which minimizes the amount of liquid that may become trapped, during use, in a drink-through lid design having a hollow raised lip portion. In one aspect, this may be accomplished by minimizing, or at least optimizing, the distance between an inner sidewall 200 of the outer lip portion 56 of the hollow raised lip portion 54 and the radially outermost edge RO of a drink outlet 34. In another yet related aspect, this may be accomplished by minimizing, or at least optimizing, the generally horizontal distance between the inner sidewall of a beverage cup and an inside wall 202 of interior portion 62 of the hollow raised lip portion 54. In an embodiment, such dimensions may provided in combination with a drink well 40 that is sufficiently deep, and/or a hollow raised lip portion 54 that is sufficiently high, that liquid flowing into a drink well 40 from a drink outlet 34 does not immediately impact a user's lips, as the liquid emerges from drink outlet 34. In another aspect, there should be adequate space below the upper edge of the drink outlet 34 to allow a big enough pool of liquid to form in the drink well 40 to create a natural, open top cup like drinking experience. Thus, in an embodiment, by (a) extending the outer lip portion 60 of the hollow raised lip portion 54 outward, to allow for both a drink outlet 34 and space for a user's lips above a liquid level in a drink well 40, (b) by making the interior portion 62 of the hollow raised lip portion 54 of a beverage cup 30 or 130 rather steep (downward, and in some embodiments, slightly inwardly sloping) but still in a manufacturable configuration for a thermoforming processes, and (c) by providing a drink outlet 34 that at least in part extends upward into the interior portion 62 of hollow raised lip portion 54, a novel drink-through lid design has been provided. With respect to dimensions D1, D2, and D3, as indicated in FIG. 21, those of skill in the art will understand that such dimensions will vary depending upon the size of a beverage container 32 on which the lid 30 is to be placed, as in many retail stores selling hot and cold beverages, sizes such as small, medium, and large (or for example, tall, grande, and vente) may be provided, with similar or differing dimensions, depending on the policy of a particular retail store.
Attention is now directed to FIG. 23, wherein further details for structure of an exemplary drink through lid 30 are provided, at a scale which enables better visualization of a suitable method for fabrication of such drink-through lids 30. Drink-through lid 30 is partially depicted, showing the interior bead sealing portion 50 in place in a snap fit fashion (see interference dimension D2 in FIG. 21) over a bead 52 of a beverage cup 32. For ease of manufacturing, lid 30 may be provided with an inwardly protruding shoulder 210, of a predetermined width along top face 212. In an embodiment the width along top face 212 may be about one tenth of an inch (0.1′′) (0.254 cm), or less. As seen by reference arrows 214 and 216, and connected by line 218 as if provided by a cutting die, a cut made, for example, by use of a vertically moving hardened metallic die downward along planes represented at reference arrows 214 and 216, can be utilized to remove excess thermoplastic material and thus define edges to provide drink outlets 34. Such stamping of drink through openings is a known practice subsequent to vacuum forming of thermoplastic material. However, the present design simplifies the manufacturing process for a drink-through lid, by use of the inwardly protruding shoulder 210, so that the thickness of a necessary cut through thermoplastic material is minimized. By provision of an inwardly protruding shoulder 210, the full benefit of the design provided herein can be easily realized, and yet such lids can be produced in large scale manufacturing operations.
It should also be noted in FIG. 23 that an angle alpha (α) is indicated, for example, as between plane 82 and the plane 80 as noted for the orientation, in an embodiment, of drink outlet 34. Although the location of angle alpha (α) is slightly offset when the inwardly protruding shoulder 210 is utilized, the reader should refer to the discussion set forth elsewhere herein as regards the particulars of such angle alpha (α).
Next, attention is directed to FIG. 24, wherein an embodiment that includes a series of drink outlets from O1, through ON, wherein N is a positive integer. As a further example a series of drink outlets 34 may be provided in a series of drink outlets from O1, O2, O3, ON-1, through ON, wherein in N is a positive integer. In FIG. 24, drink outlets O1, O2, O3, are provided. Associated with each of the drink outlets O1, O2, O3, ON-1, through ON, wherein in N is a positive integer, for example are a plurality of segments of Wi comprising Wi, Wii, Wiii, WN-1, Wn, wherein n is a positive integer. Also seen in FIG. 24 is the use of a vent passageway 122 which has an oval outlet shape.
Attention is now directed to FIGS. 25 and 26, which illustrate an embodiment for a drink-through lid for a cup 300. FIG. 25 provides a top view, taken looking down at the lid 300, and FIG. 26 provides a bottom perspective, looking up at the lower side of the lid 300. As seen in FIG. 26, lid 300 has a base 344 with rim 346 having a bottom edge 348, and an interior bead sealing portion 350. In an embodiment, rim 346 may be annular in shape. The base 344 is sized and shaped to sealingly engage an open end of beverage container (not shown in this figure, but often circular), which may be defined by a bead on the beverage container, in the manner described above. A hollow raised lip portion 354 is provided, and it has an exterior portion 356 extending upwardly from the drink well base 340, an outer lip portion 360, and an interior portion 362 sloping downwardly and inwardly from the outer lip portion 360 to lower end portions 366. A drink well base 340 for containing liquid (see FIG. 3) is provided. The drink well base 340 has a floor 363 extending from a peripheral side 364 along at least some of the lower end portions 366. At least one drink outlet 334 is provided. The at least one drink outlet 334 may be defined by a first edgewall 374 extending upward into the interior portion 362 of the hollow raised lip portion 354 and by an elongated second edgewall 376 extending along an outlet portion 378 of the drink well base 340 in proximity to the peripheral side 64.
As seen in FIG. 25, the drink-through lid 300 may include a downwardly extending wall 380 that extends transversely across the drink-through lid 300. In an embodiment, a trough shaped wall 380 may be provided, as in a downwardly directed V-shape or U-shape. In an embodiment, the trough shaped wall 380 may be provided in a chord like configuration. In an embodiment, the trough shaped wall 380 may be provided with first 382 and second 384 portions extending out radially. In an embodiment, such radially extending portions may be aligned as if in a partial chord line (extending in a chord like direction but not extending all the way to the edges of the base 344) with respect to a circular shaped base 344.
In an embodiment, a slit 386 may be provided between a first end 388 and a second end 390, and along a first edge 392 and a second edge 394 formed by wall 380. Also, an opening 400 may be provided in wall 380 as defined by first edgewall 402 in first edge 392 to define a first vent portion, and a second edgewall 404 in second edge 394 that defines a second vent portion. Together, the first vent portion and second vent portion, as provided by first edgewall 402 and second edgewall 404 in wall 380, allow for flow of vapors through the lid.
Various embodiments may be provided using various types of plastics, such as thermoplastics. In various embodiments, the combination of a lid and beverage cup may be disposable, in that they are intended only for a single use. For such uses, very inexpensive thermoplastic materials may be suitable for construction of the lids 30.
