    [0006] [006] The patent publications mentioned above are hereby incorporated by reference into this document.
    [0007] [007] Lids for drinkable liquid containers for drinkable liquid containers that contain cold drinkable liquids are also known in the art.
    [0008] [008] Plastic caps for drinking liquid containers are conventionally made from polyethylene, polyvinyl chloride, polypropylene, polystyrene and other resins. Although some of the lids made from these resins have excellent transparency, these lids have a very low rate of degradation and thus remain semi-permanently when discarded as waste and buried under the ground. The presence of these lids for a drinkable liquid container in the ocean causes damage or aesthetic destruction of the living environment of marine organisms.
    [0009] [009] Lids for conventional drinkable liquid containers are not produced from polymers based on lactic acid. During the processing of a lactic acid-based polymer using conventional molding methods, such as compression molding (thermoforming) and injection molding, the polymer does not provide caps for drinkable liquid containers that have sufficient impact resistance for practical use as lids for transparent or non-transparent drinkable liquid containers. SUMMARY OF THE INVENTION

The drinkable liquid container is versatile in that it can be adapted for use with a drinkable liquid container that contains a cold drinkable liquid, a hot drinkable liquid or a foamy or creamy drinkable liquid. The lid for the drinkable liquid container preferably includes a spout, straw perforations, a raised portion, a reservoir bottom, a cavity portion and a pair of retaining walls that prevent the direct flow of drinkable liquid from a pair of openings in the interior cover for the nozzle. The lid for the drinkable liquid container is preferably produced from a biodegradable material and, more preferably, a biodegradable polymeric material. Methods of using the drinkable liquid container are also described.
    [0011] [011] A lid for a drinkable liquid container includes an inner cover, an outer cover and a hinge that connects the inner cover to the outer cover and that is foldable to orient the outer cover over the inner cover. The interior cover has a pair of openings to allow a drinkable liquid to pass into a drinkable liquid container through the interior cover. The interior cover includes a reservoir bottom and a cavity portion that extends downwardly and outwardly from an edge of the reservoir bottom to form a cavity. The interior cover also includes a pair of retaining walls, with each retaining wall extending upward and outward from the reservoir bottom and flanking one side of the cavity portion and one side of one between the pair of openings. , in which each retaining wall extends inwards, passing through an edge of the opening. The inner cover also includes an outer rim that extends around an outer edge of the reservoir bottom, the cavity portion and the retaining walls and that is formed to receive a rim of the drinkable liquid container and an inner rim that extends. extends inward from the outer edge of the inner cover. The outer cover has an outer edge dimensioned to be received by the inner edge of the inner cover. The outer cover includes a flat portion extending inwardly from the outer edge of the outer cover, a nozzle extending upward from the flat portion and an elevated portion extending upward from an edge of the flat portion .
    [0012] [012] The inner cover, outer cover and hinge are arranged so that when the hinge is folded and the outer edge of the outer cover is received by the inner edge of the inner cover, the nozzle is located above the cavity portion and each retaining wall contacts the flat portion of the outer cover, thereby preventing a drinkable liquid in the drinkable liquid container from flowing directly from the openings to the spout.

    [0026] [026] A lid for a drinkable liquid container is formed to have a liquid cooling effect in some embodiments and is spill-proof with a high portion. The lid for the drinkable liquid container is versatile in that it can be used with all types of cold, hot and foamy drinkable liquids.
    [0027] [027] The lid for the drinkable liquid container includes an outer cover and an inner cover connected by a hinge. In some embodiments, the lid for the drinkable liquid container includes a raised portion, a perforated reservoir bottom, a straw perforation and a spout. In some embodiments, the raised portion has steep sides and a flat top surface. In other embodiments, the raised portion is curved to form a dome shape. In some embodiments, the dome shape is hemispherical. These features make the lid for drinkable containers universal by the fact that it can be used in all types of cups or drinkable containers that include, but are not limited to, hot, cold, foamy or creamy. A foamy or creamy drinkable liquid, as used in this document, can be any drinkable liquid with a top layer of foam or cream added to the top surface of the liquid drink, such as a coffee drink mixed with whipped cream on top of the coffee. The dome allows the merchant to add the top layer to a level above the rim of the drinkable container without the top layer touching the lid. The dome also provides more space under the lid for the user to mix the drink properly with the use of a straw.
    [0028] [028] When the drinkable liquid cap is used with a hot drinkable liquid cap, the drinkable liquid cap is a spill-free and burn-free cap with a perforated reservoir, a straw perforation and a spout and is preferably used in the following manner. The inner cover that includes the reservoir bottom is simply placed on top of the container and the hinge is folded to place the outer cover over the inner cover. The edge of the outer cover is inserted into an inner edge of the inner cover to hold the outer cover in place. The cap on the spout is removed and the user can then enjoy the hot drinkable liquid by drinking through the spout.
    [0029] [029] When the drinkable liquid cap is used with a foamy or creamy mix drinkable liquid cap, the drinkable liquid cap includes a raised portion with a straw perforation and a spout and is preferably used in the proper manner. Next. The cavity portion is pulled along the reservoir perforation and the reservoir perforation is also broken to detach from the reservoir bottom of the inner cover. Only the raised portion can be used alone, simply placing the inner cover around the rim of the container and then folding the hinge to place the outer cover over the inner cover. A straw is guided through the perforation of the straw in the outer cover and the drinkable liquid of foamy or creamy mixture is ready to be enjoyed. The raised portion allows more whipped cream or another top layer to be added to the top of the drinkable liquid without touching the lid.
    [0030] [030] When the lid for drinkable liquid container is used with a cold drinkable liquid container, the lid for drinkable liquid container is spill-free with a straw hole, a spout and a perforated reservoir and is preferably used as follows . The inner cover that includes the reservoir is simply placed on top of the container and the hinge is folded to place the outer cover over the inner cover. A straw is guided through the straw hole in the outer cover and the straw hole in the inner cover and the cold drinkable liquid is ready to be enjoyed. Alternatively, the cap on the spout can be removed and the user can then enjoy the cold drinkable liquid by drinking through the spout. This innovative feature also allows the merchant to eliminate the use of a conventional straw when serving cold drinks that include, but are not limited to, soda and juice, which is more cost effective for the merchant and better for the environment. environment.
    [0031] [031] The volume of the reservoir prevents spills resulting from any accidental and unjustified shaking, tilting or falling from the drinkable liquid container.
    [0032] [032] The inner cover is preferably designed to press the rim of the drinkable container by pressure and the outer cover is designed to be received by the inner cover when the hinge is folded. The inner cover and the outer cover are connected by the hinge and, as part of the design, the hinge is folded outside the rim of the cup and not inside the rim. For these reasons, it is not desirable to break the hinge and place only the outer cover in the drinkable liquid container, when using the drinkable liquid lid with a drinkable liquid with a foamy or creamy mixture. If the inner cover and outer cover are to be joined before they are placed in the drinkable liquid container, the hinge can be folded between the drinkable liquid cover and the rim of the drinkable liquid container, which can create a gap between the lid for the drinkable liquid container and the drinkable liquid container to cause leakage. The inner cover seals the drinkable container first, and then the outer cover is folded over, so that the hinge folds out of the rim of the drinkable container and is not caught between the lid and the rim of the container. of drinkable liquid to cause any leakage.
    [0033] [033] In some embodiments, the drinkable liquid cap eliminates the need for a drinking straw as a result of a Sippy cup design with a mouthpiece or a spout with a perforated top at the top that can be rotated or removed before consumption. The elimination of a straw for drinkable liquid containers not only saves money for the merchant, but also avoids the unnecessary production of waste, which preserves a better and less polluted environment. The protruding spout with a perforated top eliminates the spillage of drink out of a glass of transported drinkable liquid and eliminates the use of a drinking straw.
    [0034] [034] In some embodiments, the lid for the drinkable liquid container is degradable and, more specifically, biodegradable. In some embodiments, the lid material for the drinkable liquid container includes a degradable thermoplastic polymer composition in a natural environment and with excellent transparency and impact resistance.
    [0035] [035] In some embodiments, the lid for the drinkable liquid container is produced from a transparent biodegradable material, so that the contents of the drinkable liquid container can be determined visually. In some embodiments, the biodegradable material is a copolymer of polyhydroxybutyrate (PHB), poly (hydroxybutyrate-co-hydroxyvalerate) (PHBV), a polylactic acid or other polymer based on lactic acid. A lactic acid-based polymer, as used herein, refers to polylactic acid or any copolymer of polylactic acid and another hydroxycarboxylic acid.
    [0036] [036] When the biodegradable polymeric material is placed in the soil or in seawater, it begins to decompose within a few weeks in a humid environment and disappears within a few years. In addition, the final degradation products of these polymers are lactic acid, carbon dioxide and water, which are not toxic to humans.
    [0037] [037] In some embodiments, the lid for the drinkable liquid container is produced from a biodegradable thermoplastic polymeric composition of a lactic acid-based polymer that has a molecular weight of at least 10,000. In some embodiments, the biodegradable thermoplastic polymeric composition has a light transmission of at least 85%. In some embodiments, the biodegradable thermoplastic polymeric composition has a light transmission of at least 90%. In some embodiments, the thermoplastic polymeric composition is transparent. In other embodiments, the thermoplastic polymeric composition is not transparent.
    [0038] [038] In some embodiments, the lid for the drinkable liquid container is formed by pre-forming a thermoplastic polymeric composition at a preform temperature in the range of 180 ° C to 300 ° C and molding by stretching and blowing the preform in the lid for drinkable liquid container at a molding temperature ranging from 20 ° C to 125 ° C. In some embodiments, the preform is a formwork and the stretch and blow molding is a stretch and blow extrusion molding, injection or compression molding or thermoforming molding. The molding temperature preferably corresponds to the glass transition temperature (Tg) of the thermoplastic polymeric composition, as the variation from Tg to Tg + 60 ° C. The stretch ratio is preferably in the range of 1.2 to 6 times, when the glass transition temperature is in the range of 20 ° C to 65 ° C.
    [0039] [039] The thermoplastic polymeric composition can be formed from units of monomers of L-lactic acid, D-lactic acid, glycolic acid or any other combination thereof.
    [0040] [040] A lid for a degradable drinkable liquid container is preferably degraded in a natural environment and has sufficient transparency and impact resistance for practical use and shipping in the event of a sudden drop in the drinkable liquid container.
    [0041] [041] Figure 1 shows a schematic perspective view of a lid for a drinkable liquid container 10 with a substantially flat top in a closed position. The outer cover 12 is folded over the inner cover 14, the hinge 16 connecting the outer cover 12 and the inner cover 14. The inner cover 14 includes an outer rim 18 that seals the inner cover 14 around the rim. a drinkable liquid container. A spout 20 on the outer cover 12 allows the user to drink a drinkable liquid in the drinkable liquid container. An opening, which is not visible in Figure 1, allows the drinkable liquid to enter a reservoir space formed between the outer cover and the inner cover. A pair of retaining walls, which is not visible in Figure 1, formed on the inner cover 14 extends to indentations 27, 29 on the outer cover 12 to prevent liquid from flowing over the retaining walls. Instead, the drinkable liquid from the drinkable liquid container must flow through the opening in the inner cover, around the retaining walls and to the spout 20. These indentations 27, 29 look like protrusions when viewed from the top of the outer cover , as shown in Figure 1. The top surface of the raised portion 22 of the outer cover 12 is substantially flat. A small hole 24 at the top of the lid ventilates the interior space, so that no vacuum is formed and the drink can easily flow out of the spout towards the user's mouth. A sloping area or ditch 26 behind the spout 20 receives the user's upper rim, provides a comfortable sip and captures and collects any possible excessive flow of drinkable liquid after each sip. A straw perforation 28 allows the user to insert a straw through the outer cover 12 of the drinkable liquid lid 10.
    [0042] [042] Although the details of the inner cover 14 are not visible in Figure 1, the inner cover 14 can have any of the features or any combination of the features of the inner covers 34 shown in Figure 2 through Figure 13, being within the character of the present invention.
    [0043] [043] Figure 2 shows the top surfaces of the inner cover 34 and the bottom surfaces of the outer cover 32 of a lid for drinkable liquid container 30 with an elevated portion 46 in an embodiment of the present invention. A hinge 36 flexibly connects the outer cover 32 to the inner cover 34. An outer rim 38 around the edge of the inner cover 34 affixes the inner cover 34 to the rim of a drinkable liquid container. An inner lip 39 on the inner cover 34 receives the lip 33 of the outer cover 32 to form a seal between the outer cover 32 and the inner cover 34, thereby forming a reservoir space between the covers 32, 34. A nozzle 40 on the outer cover 32 allows the user to drink a drinkable liquid in the drinkable liquid container. A small hole 24 in the outer cover 32 ventilates the interior space, so that no vacuum is formed and the drink can easily flow out of the spout and into the user's mouth.
    [0044] [044] A spout cap 41 on spout 40 blocks spout 40 until the user is ready to start drinking through spout 40 and remove spout cap 41 along a perforation. A pair of openings 52, 54 allows the drinkable liquid to enter a reservoir space formed between the outer cover 32 and the inner cover 34. A small hole 35 in the inner cover 34 ventilates the drinkable container, so that no vacuum is formed and the drink can flow through the openings 52, 54. A pair of retaining walls 42, 44 flank the openings 52, 54, respectively, to prevent drinkable liquid from flowing directly from the openings 52, 54 to the spout 40. The tops of the retaining walls 42, 44 contact a flat portion 48 of the outer cover 12. The raised portion 46 of the outer cover 32 is domed in Figure 2, except for a flat portion on which a straw perforation 50 is located. The perforation of straw 50 allows the user to insert a straw through the outer cover 32 of the lid for drinkable liquid container 30.
    [0045] [045] A reservoir bottom 56 formed in the inner shell 34 forms the bottom edge of the reservoir formed between the inner shell 34 and the outer shell 32. A portion of cavity 58 between the retaining walls 42, 44 extends below the level from the reservoir bottom 56. A straw perforation 60 located in the reservoir bottom 56 allows the user to insert a straw through the inner cover 34 of the drinkable liquid cap 30. A reservoir perforation 62 allows the reservoir bottom 56 , the retaining walls 42, 44 and the cavity portion 58 are removed from the remainder of the inner cover 34.
    [0046] [046] Figure 3 shows a side profile view of the lid for drinkable liquid container 30 of Figure 2. The shapes of the raised portion 46, the cavity portion 58, the flat portion 48 around the nozzle 40 and the surrounding areas around the straw perforations 50, 60 are more clearly visible in the view of Figure 3. Figure 3, as well as Figure 4 and Figure 5, also shows that the openings 52, 54 are located above the surface of the reservoir bottom 56 , so that after the drinkable liquid container is placed back down after the first sip, some of the drinkable liquid inside the reservoir is drained back into the drinkable container, but some of the drinkable liquid remains scattered on the bottom of reservoir 56, in addition to the little that is trapped in the cavity portion 58. In the case of a hot drinkable liquid, that liquid that remains cools and mixes with the hot drinkable liquid that enters the reservoir again through the openings 52, 54 par a the next drink coming out of the cup, which is how the temperature of the hot drinkable liquid is lowered to prevent the user’s mouth from burning. In some embodiments, the openings 52, 54 are located approximately 3 millimeters above the surface of the reservoir bottom 56.
    [0047] [047] Figure 4 shows a front view of the lid for drinkable liquid container 30 in a closed position. The raised portion 50 extends upwardly behind the nozzle 40. A pair of indentations 63, 64 allows a user to easily hold the cavity portion 58 with their fingers or nails and pull the cavity portion 58 to break the perforation 62 between the cavity portion 58 and the outer edge of the inner cover 34.
    [0048] [048] Figure 5 shows a side view of the lid for drinkable liquid container 30 in a closed position with a straw 66 inserted through the straw perforations 50, 60. The straw perforation 60 of the inner cover 34 is preferably small to minimize the passage of drinkable liquid through the perforation of straw 60 around straw 66 and in the reservoir space, in the event of an accidental and unjustified stirring, tilting or dropping of the drinkable liquid container. The perforation of straw 60 of the inner cover 34 is also located in a depression in the bottom of reservoir 56, as shown in Figure 5, in order to help the user locate the perforation of straw 60 during insertion of a straw 66. The perforation straw 50 on the outer cover 32 is preferably larger than the perforation of straw 60 on the inner cover 34, as shown in Figure 2, so that the user is able to position the straw 66 at a greater angle without flexing the straw 66 in order to be able to drive the bottom of the straw 66 to a bottom edge of the drinkable liquid container. A preferred shape of the outer rim 38 is also shown in Figure 5.
    [0049] [049] Figure 6 shows a top view of the lid for drinkable liquid container 30 in a closed position to show the relative positions of the openings 52, 54, the retaining walls 42, 44 and the cavity portion 58 in relation to the spout 40.
    [0050] [050] Figure 7 shows a closed side view of the lid for the drinkable liquid container similar to Figure 5, except that the reservoir bottom is separated along with the reservoir perforation and removed from the lid for the drinkable liquid container.
    [0051] [051] Although the outer cover 32 is shown to be flat in the area around the nozzle 40 in Figures 2 to 7, the outer cover 32 may have indentations similar to the indentations 27, 29 shown in Figure 1, within the character of this invention. The tops of the retaining walls 42, 44 formed in the inner cover 34 extend into the indentations in the outer cover 32 to prevent a liquid from flowing over the retaining walls 42, 44. Instead, the drinkable liquid from the drinkable liquid container should flow through the openings 52, 54 in the inner cover, around the retaining walls 42, 44 and towards the nozzle 20. These indentations look like protrusions when viewed from the top of the outer cover 72.
    [0052] [052] In relation to Figure 2 to Figure 7, in a method of using a lid for a drinkable liquid container, the inner cover 34 is placed over the drinkable liquid container that contains a drinkable liquid, placing the rim outer 38 around the rim of the drinkable liquid container. The hinge 36 is folded, the outer cover 32 is placed over the inner cover 34 and the edge 33 of the outer cover 32 is inserted under the inner edge 39 of the inner cover 34. Finally, the nozzle cap 41 is removed from the nozzle 40 and a user can then enjoy the drinkable liquid by placing the nozzle 40 in his mouth and sipping the drinkable container towards the nozzle 40. In this method, the drinkable liquid is preferably a hot drinkable liquid. The hot drinkable liquid enters the reservoir volume through the openings 52, 54. The retaining walls 42, 44 prevent the drinkable liquid from flowing directly to the spout 40. Instead, the drinkable liquid must first flow around the walls 42, 44 towards the bottom of the reservoir 56. When the user pauses drinking and deposits the drinkable liquid perpendicularly on a flat surface, some of the drinkable liquid in the reservoir volume flows back into the drinking container. drinkable liquid through openings 52, 54, but a little flows into the portion of cavity 58 which is directly below the spout 40, where it is retained and is able to cool until the user is ready to sip again.
    [0053] [053] In another method of using the lid for drinkable liquid container, the perforation of reservoir 62 together with the cavity portion 58 and the retaining walls 42, 44 is separated. This is preferably accomplished by holding the indentations 63, 64 that flank the cavity portion 58 with two fingers in one hand, holding the outer rim 38 with the other hand and pulling up to separate the reservoir perforation 62. A the posterior pull then separates the entire reservoir perforation 62 and the portion including the reservoir bottom 56, the cavity portion 58 and the retaining walls 42, 44, which is discarded. The inner cover 34 is then placed over the drinkable liquid container containing a drinkable liquid, the outer rim 38 being placed around the rim of the drinkable container. The hinge 36 is folded, the outer cover 32 is placed over the inner cover 34 and the edge 33 of the outer cover 32 is inserted under the inner edge 39 of the inner cover 34. Finally, a straw 66 is inserted through the perforation of straw 50 and in the drinkable liquid container and a user can then enjoy the drinkable liquid by sucking it through the straw 66. In this method, the drinkable liquid is preferably a drinkable liquid with a foamy or creamy mixture. In some embodiments, however, the drinkable liquid can be a cold drinkable liquid.
    [0054] [054] In another method of using the lid for the drinkable liquid container, the inner cover 34 is placed over the drinkable liquid container containing a drinkable liquid, placing the outer rim 38 around the rim of the drinkable liquid container. . The hinge 36 is folded, the outer cover 32 is placed over the inner cover 34 and the edge 33 of the outer cover 32 is inserted under the inner edge 39 of the inner cover 34. Finally, a straw 66 is inserted through both perforations of straw 50, 60 and in the drinkable liquid container and a user can then enjoy the drinkable liquid by sucking it through straw 66. In this method, the drinkable liquid is preferably a cold drinkable liquid.
    [0055] [055] Figure 8 shows the top surfaces of the inner cover 34 and the bottom surfaces of the outer cover 72 of a lid for drinkable liquid container 70 with an elevated flat top portion 74 in an embodiment of the present invention. A hinge 36 flexibly connects the outer cover 72 to the inner cover 34. An outer rim 38 around the edge of the inner cover 34 affixes the inner cover 34 to the rim of a drinkable liquid container. An inner lip 39 on the inner cover 34 receives the lip 33 of the outer cover 72 to form a seal between the outer cover 72 and the inner cover 34, thereby forming a reservoir space between the covers 72, 34. A nozzle 40 in the outer cover 72 it allows the user to drink a drinkable liquid in the drinkable liquid container. A small hole 24 in the outer cover 72 ventilates the interior space, so that no vacuum is formed and the drink can easily flow out of the spout and into the user's mouth.
    [0056] [056] A spout cap 41 on spout 40 blocks spout 40 until the user is ready to start drinking through spout 40 and remove spout cap 41 along a perforation. A pair of openings 52, 54 allows the drinkable liquid to enter a reservoir space formed between the outer cover 72 and the inner cover 34. A small hole 35 in the inner cover 34 ventilates the drinkable liquid container, so that no vacuum is formed and the drink can flow through the openings 52, 54. A pair of retaining walls 42, 44 flank the openings 52, 54, respectively, to prevent drinkable liquid from flowing directly from the openings 52, 54 to the spout 40. The tops of the retaining walls 42, 44 contact a flat portion 48 of the outer cover 12 around the nozzle 40. The flat top portion 74 of the outer cover 72 includes a straw perforation 50, which allows the user to insert a straw through the outer cover 72 of the drinkable container cap 70.
    [0057] [057] A reservoir bottom 56 formed in the inner shell 34 forms the bottom edge of the reservoir formed between the inner shell 34 and the outer shell 72. A portion of cavity 58 between the retaining walls 42, 44 extends below the level from the reservoir bottom 56. A straw perforation 60 located on the reservoir bottom 56 allows the user to insert a straw through the inner cover 34 of the drinkable liquid cap 70. A reservoir perforation 62 allows the reservoir bottom 56 , the retaining walls 42, 44 and the cavity portion 58 are removed from the remainder of the inner cover 34.
    [0058] [058] Figure 9 shows a side profile view of the lid for drinkable container 70 of Figure 8. Figure 9, as well as Figure 10 and Figure 11, shows that the openings 52, 54 are located above the surface from the bottom of reservoir 56, so that after the drinkable liquid container is placed back down after the first sip, some of the drinkable liquid inside the reservoir is drained back into the drinkable liquid container, but a little of the drinkable liquid remains scattered on the bottom of reservoir 56, in addition to the little that is trapped in the portion of cavity 58. In the case of a hot drinkable liquid, this remaining liquid cools and mixes with the hot drink that enters the reservoir again through the openings 52, 54 for the next drink coming out of the cup, which is how the temperature of the hot drinkable liquid is lowered to prevent the user’s mouth from burning. In some embodiments, the openings 52, 54 are located approximately 3 millimeters above the surface of the reservoir bottom 56.
    [0059] [059] Figure 10 shows a front view of the lid for the drinkable liquid container 70 in a closed position. The raised portion 50 extends upwardly behind the nozzle 40. A pair of indentations 63, 64 allows a user to easily hold the cavity portion 58 with their fingers or nails and pull the cavity portion 58 to break the perforation 62 between the cavity portion 58 and the outer edge of the inner cover 34.
    [0060] [060] Figure 11 shows a side view of the lid for drinkable liquid container 70 in a closed position with a straw 66 inserted through the straw perforations 50, 60. The straw perforation 60 of the inner cover 34 is preferably small to minimize the passage of a drinkable liquid through the perforation of straw 60 around straw 66 and in the reservoir space, in the event of an accidental and unjustified agitation, tilt or drop of the drinkable container. The straw perforation 60 of the inner cover 34 is also located in a depression at the bottom of reservoir 56, as shown in Figure 11, in order to help the user locate the perforation of straw 60 during the insertion of a straw 66. The perforation straw 50 on the outer cover 72 is preferably larger than the perforation of straw 60 on the inner cover 34, as shown in Figure 8, so that the user is able to position the straw 66 at a greater degree angle without flexing the straw 66 in order to be able to drive the straw 66 to a bottom edge of the drinkable liquid container. A preferred shape of the outer rim 38 is also shown in Figure 11.
    [0061] [061] Figure 12 shows a top view of the lid for drinkable liquid container 70 in a closed position to show the relative positions of the openings 52, 54, the retaining walls 42, 44 and the cavity portion 58 in relation to the spout 40.
    [0062] [062] Although the outer cover 72 is shown to be flat in the area around the nozzle 40 in Figures 8 through 12, the outer cover 72 may have indentations similar to the indentations 27, 29 shown in Figure 1, within the character of the present invention. . The tops of the retaining walls 42, 44 formed in the inner cover 34 extend into the indentations in the outer cover 72 to prevent a liquid from flowing over the retaining walls 42, 44. Instead, the drinkable liquid in the drinkable liquid container should flow through the openings 52, 54 in the inner cover 34, around the retaining walls 42, 44 and to the nozzle 20. These indentations look like protrusions when viewed from the top of the outer cover.
    [0063] [063] Figure 13 shows a closed side view of the lid for drinkable liquid container similar to Figure 11, except that the reservoir bottom is separated along with the reservoir perforation and removed from the lid for drinkable liquid container.
    [0064] [064] The reservoir prevents spills resulting from any accidental and unjustified shaking, tilting or falling from the drinkable liquid container.
    [0065] [065] Consequently, it should be understood that the modalities of the invention described in this document are merely illustrative of the application of the principles of the present invention. The references made in this document to details of the illustrated modalities are not intended to limit the scope of the claims, which themselves report those features considered essential to the present invention.
