Description

A cup lid that can maintain a constant beverage concentration

[0001] The present invention relates to a functional cup lid. More specifically, it relates to a tumbler cup lid capable of maintaining a constant concentration of a beverage, such as iced coffee, in a beverage cup.

[0002] Generally, when pouring iced coffee or other beverages into a disposable cup or tumbler, place the cup lid over the cup body to prevent foreign substances from entering and to prevent the beverage from spilling out.

[0003] Disposable cups typically have a hemispherical, transparent lid for cold beverages like iced coffee, while flat white or black disposable lids are used for hot beverages. Tumblers typically have a circular plastic or metal lid, regardless of the beverage temperature. They typically feature a hole or cap in the center for inserting a straw.

[0004] Meanwhile, iced coffee is typically served by pouring ice, a small amount of water, and a strong espresso into a cup. In this case, the amount of water is small, so the coffee is initially very strong. However, as time passes, the ice melts and turns to water, gradually diluting the coffee's strength. In this case, you'll initially drink a very strong cup, but gradually, the coffee will become weaker. The problem with slowing down the coffee is that, by the end, you'll end up with a cup that tastes almost like water.

[0005] The present invention aims to solve all of the above-described problems.

[0006] The purpose of the present invention is to provide a cup lid capable of providing a constant concentration of an iced beverage.

[0007] In addition, the present invention aims to provide a cup lid that allows a user to easily control the amount of concentrate discharged to maintain the concentration of an iced beverage according to the user's beverage consumption time so as to maintain the concentration of the beverage at a constant level.

[0008] According to one embodiment of the present invention, a cup lid of a beverage cup capable of containing a beverage comprises: a lid body portion having an inside space formed to accommodate a beverage concentrate and capable of covering an upper portion of the beverage cup; a beverage concentrate injection port formed on a portion of a surface of the lid body portion such that the outside of the lid body portion is connected to the inside of the accommodation space; an outlet portion formed from a bottom surface inside the accommodation space to a lower surface of the lid body portion such that the beverage concentrate accommodated inside the accommodation space can be discharged to the outside in a downward direction of the cup lid; a discharge valve having a threaded line formed on an inner surface of the passage such that the discharge valve is formed to correspond to an inner shape of the discharge port so as to be able to seal the discharge port, and having a threaded line formed on an outer surface corresponding to a threaded line formed on an inner surface of the discharge port; And it includes a discharge amount control handle formed on the outside of the lid body part, which is connected to the discharge valve and rotates the discharge valve to control whether the discharge valve is sealed and the gap between the discharge valve and the discharge port, thereby controlling the amount of the beverage concentrate flowing out into the space between the discharge port and the discharge valve.

[0009] By using the cup lid according to the present invention, the first high-concentration concentrate contained in the cup and the second high-concentration concentrate contained in the cup lid are separately contained, and the second high-concentration concentrate is slowly dropped into the cup by the user through the control handle attached to the cup lid, so that even if the ice inside the cup melts, the user can drink a beverage of a constant concentration due to the high-concentration concentrate being slowly added.

[0010] In addition, by using the cup lid according to the present invention, the user can control the control valve according to his / her choice in response to various beverage consumption times, such as fast drinking and slow drinking, thereby controlling the discharge amount of the high-concentration concentrate contained in the cup lid, so that the user can drink a beverage of a constant concentration even if the beverage consumption time of the user varies.

Furthermore, it should be understood that the positions or arrangements of individual components within each disclosed embodiment may be modified without departing from the spirit and scope of the present invention. Accordingly, the following detailed description is not intended to be limiting, and the scope of the present invention is defined only by the appended claims, along with the full scope of equivalents to which such claims are entitled, if properly described. Like reference numerals in the drawings designate the same or similar functionality throughout the several aspects.

[0032] Hereinafter, in order to enable a person having ordinary skill in the art to easily practice the present invention, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

[0033] Figure 1 shows a cross-sectional view of a cup lid according to one embodiment of the present invention.

[0034] Referring to FIG. 1, a cup lid (100) according to one embodiment of the present invention includes a lid body portion (110), a beverage concentrate inlet (120), an inlet stopper (130), a receiving space (140), a discharge port (150), a discharge valve (160), an amount of discharge control handle (170), and a worm gear portion (180).

[0035] A cup lid (100) is a lid for a beverage cup, such as a tumbler, that can hold a beverage. It may be made of transparent plastic material or may be made of plastic material of a different color. In addition, if the cup lid is a tumbler lid, it may be made by combining a plastic material part with a metal or ceramic material.

[0036] The lid body (110) of the cup lid (100) has a space (140) formed therein that can accommodate a beverage concentrate, and covers the upper part of the beverage cup to protect the beverage contained in the cup.

[0037] The beverage concentrate injection port (120) is formed in the form of a hole on a portion of the upper surface of the lid body (110) and serves to connect the exterior of the lid body (110) to the interior of the receiving space (140). In addition, the injection port stopper (130) serves to open and close the beverage concentrate injection port (120).

[0038] The discharge port (150) is formed by extending from the bottom surface inside the receiving space to the bottom surface of the lid body (110). The discharge port (150) serves as a passage that allows the beverage concentrate contained inside the receiving space (140) to be discharged outside the cup lid in a downward direction of the cup lid (100). In addition, it is preferable that a screw line is formed on the inner surface of the discharge port (150). Meanwhile, it is preferable that the bottom surface inside the receiving space is formed to be slightly inclined so that the discharge port (150) is located at the lowest surface.

[0039] The discharge valve (160) is a valve formed in a shape corresponding to the internal shape of the discharge port (150). The discharge valve (160) functions as a valve capable of sealing the discharge port (150) and, if necessary, partially opens the passage of the discharge port (150) so that beverage concentrate can be discharged through the discharge port (150). To this end, the side surface, i.e., the outer surface, of the discharge valve (160) is formed corresponding to the screw thread formed on the inner surface of the discharge port (150).

[0040] The discharge amount control handle (170) is formed on the outside of the lid body (110) and is directly connected to the discharge valve (160) or indirectly through a worm gear (180) or the like as shown in FIG. 1 to rotate the discharge valve (160) and control the sealing and gap between the discharge valve (160) and the discharge port (150). Accordingly, the discharge amount control handle (170) functions to control the amount of beverage concentrate contained in the receiving space (140) that flows out into the space between the discharge port (150) and the discharge valve (160).

[0041] For this purpose, the discharge valve (160) includes an O-ring (190) for sealing between the discharge port (150) and the discharge valve (160) when the discharge valve (160) is tightened below a predetermined height in at least one area.

[0042] The worm gear unit (180) is a component that functions as a worm gear or equivalent rotational transmission mechanism connecting the discharge control knob (170) and the discharge valve (160). This allows the discharge control knob (170) to be designed to be positioned at a different location, regardless of the location of the discharge valve (160). That is, even if the discharge valve (160) is positioned at the center of the cup lid (100), the discharge control knob (170) can be designed to be positioned at the edge or side.

[0043] Meanwhile, referring to FIG. 1, the discharge port (150) has an inner diameter that becomes narrower from the inner bottom surface of the upper portion receiving space (140) to the lower surface of the lid body (110), and the discharge valve (160) also has an outer diameter that becomes narrower from the top to the bottom, correspondingly. In addition, the discharge valve (160) rotates along the inner thread of the discharge port (150) according to the adjustment of the discharge amount adjustment handle (170), thereby adjusting the height from the discharge port (150), and accordingly, the gap between the discharge port (150) and the discharge valve (150) is adjusted.

[0044] FIG. 2 exemplarily shows the opening and closing of the outlet of a cup lid according to one embodiment of the present invention.

[0045] Referring to FIG. 2, for example, when the discharge control knob (170) is turned all the way in one direction, the discharge valve (160) rotates in response to the rotation of the discharge control knob (170), so that the outer surface thread of the discharge valve (160) rotates downward along the inner surface thread of the discharge port (150), and the O-ring (190) at the top of the discharge valve (160) seals the inlet of the discharge port (150), so that the discharge port (150) is completely sealed. As a result, the beverage concentrate contained inside the receiving space (140) of the cup lid (100) is not discharged downward.

[0046] If the discharge amount control knob (170) is turned in the opposite direction, the discharge valve (160) rotates in the opposite direction in response to the rotation of the discharge amount control knob (170), and the outer surface thread of the discharge valve (160) rotates in the opposite direction along the inner surface thread of the discharge port (150) and rises upward, and a gap is created between the discharge valve (160) and the discharge port (150). This causes the beverage concentrate contained inside the receiving space (140) of the cup lid (100) to be discharged downward little by little. If the discharge amount control knob (170) is rotated a little more, the gap between the discharge valve (160) and the discharge port (150) becomes larger, and the amount of the beverage concentrate flowing out into the lower cup through the discharge port (150) can increase.

[0047] That is, by rotating the discharge control knob (170), it is possible to prevent the beverage concentrate from flowing down the discharge port (150) and to control the amount of the beverage concentrate flowing into the cup below through the discharge port (150) per hour.

[0048] When providing a beverage mixed with ice, such as an iced Americano, a cup is filled with ice, a small amount of water, and espresso coffee. If the iced coffee is provided in this manner, the coffee will be too strong at first and will become too weak over time. Therefore, in the present invention, an Americano coffee is provided by adding ice, or ice and water, to a first high-concentration concentrate, for example, espresso coffee, or strong-concentration coffee, in a beverage cup (not shown), and at the same time, the discharge amount control knob (170) of the cup lid (100) is turned to lock the discharge port (150), and then the inlet cap (130) is opened to additionally inject a second high-concentration concentrate, for example, espresso coffee, or strong-concentration coffee, through the beverage concentrate inlet (120).

[0049] Thereafter, a user using the cup lid (100) according to the present invention divides the espresso coffee initially put into the cup, puts one portion into the cup, and puts another portion into the inner receiving space (140) of the cup lid (100). Then, depending on the time for drinking the coffee, the user turns the discharge control knob (170) to adjust the discharge hole of the discharge port (150), and causes the second high-concentration concentrate, for example, espresso coffee or strong-concentration coffee, contained in the receiving space (140) to fall into the cup. Then, as the time for the user to drink the coffee passes, even if the ice inside the cup melts, the concentration of the coffee being consumed can be maintained constant by the espresso coffee slowly added through the cup lid (100).

[0050] In addition, by using the cup lid (100) according to the present invention, the user can adjust the discharge amount control knob (170) according to the user's choice in response to various beverage consumption times, such as a type where the user drinks the beverage quickly or a type where the user drinks the beverage slowly, thereby controlling the discharge amount of the second high-concentration concentrate contained in the cup lid, thereby enabling the user to drink a beverage of a constant concentration even if the user's beverage consumption time varies.

[0051] Figure 3 shows a cross-sectional view of a cup lid according to another embodiment of the present invention.

[0052] The cup lid (200) according to another embodiment illustrated in FIG. 3 has a structure similar to that of the cup lid (100) illustrated in FIG. 1. However, in the case of the cup lid (200) illustrated in FIG. 3, the receiving space (140) is formed to be tilted to one side so that the straw (220) can pass through the straw hole (210) of the cup lid (200). In this case, the discharge port (150) and the discharge valve (160) can be positioned in a straight line, so that components such as a worm gear unit may be unnecessary.

[0053] Figure 4 shows a cross-sectional view of a cup lid according to another embodiment of the present invention.

[0054] Referring to FIG. 4, a cup lid (300) according to one embodiment of the present invention includes a lid body (310), a beverage concentrate inlet (320), an inlet stopper (330), a receiving space (340), a discharge outlet (350), a discharge valve (360), and an exhaust volume control handle (370).

[0055] A cup lid (300) is a lid for a beverage cup, such as a tumbler, that can hold a beverage. It may be made of transparent plastic material or may be made of plastic material of a different color. In addition, if the cup lid is a tumbler lid, it may be made by combining a plastic material part with a metal or ceramic material.

[0056] The lid body (310) of the cup lid (300) has a space (340) formed therein that can accommodate a beverage concentrate, and covers the upper part of the beverage cup, thereby protecting the beverage contained in the cup.

[0057] The beverage concentrate injection port (320) is formed in the form of a hole on a portion of the upper surface of the lid body (310) and serves to connect the exterior of the lid body (310) to the interior of the receiving space (340). In addition, the injection port stopper (330) serves to open and close the beverage concentrate injection port (320).

[0058] The discharge port (350) is formed by extending from one bottom surface inside the receiving space to the bottom surface of the lid body (310). The discharge port (350) functions as a passage that allows the beverage concentrate contained inside the receiving space (340) to be discharged outside the cup lid in the downward direction of the cup lid (300). The bottom surface of the discharge port (350) is blocked, and a step exists between the bottom surface and the bottom surface of the lid body (310), and a hole (351) is formed in a part of the step surface. That is, the discharge port (350) is formed by extending from one bottom surface inside the receiving space (340) to the bottom surface of the lid body, but the bottom surface is blocked, and a passage is formed through which the beverage concentrate can fall through the first hole (351) formed on one side of the upper portion of the bottom surface. Meanwhile, it is preferable that the bottom surface inside the receiving space be formed to be slightly inclined so that the discharge port (350) is located at the lowest surface.

[0059] The discharge valve (360) is a valve formed in a shape corresponding to the internal shape of the discharge port (350). The discharge valve (360) functions as a valve capable of sealing the discharge port (350) and, if necessary, partially opens the passage of the discharge port (350) so that the beverage concentrate can be discharged through the discharge port (350). That is, the discharge valve (360) is formed to correspond to the internal shape of the discharge port (350) so as to seal the discharge port (350), and a passage is formed inside it so that the beverage concentrate contained inside the receiving space (340) can be discharged to the outside in the downward direction of the cup lid (300), and the internal passage is formed from a second hole (361) formed in an area of ​​the upper surface or the upper side to a third hole (362) formed in an area of ​​the lower side.

[0060] The discharge amount control handle (370) is formed on the outside of the lid body (310) and is directly or indirectly connected to the discharge valve (360) to rotate the discharge valve (360), thereby controlling the discharge amount by adjusting the sealing between the discharge valve (360) and the discharge port (350) and the size of the overlap between the first hole (351) and the third hole (362). Accordingly, the discharge amount control handle (370) functions to control the amount of beverage concentrate contained in the receiving space (340) that flows out through the internal passage of the discharge valve (360) into the space where the first hole (351) of the discharge port (350) and the third hole (362) of the discharge valve (360) overlap.

[0061] For this purpose, the discharge valve (360) includes an O-ring (not shown) for sealing between the discharge port (350) and the discharge valve (360) when the discharge valve (360) is tightened below a predetermined height in at least one area.

[0062] Figure 5 shows the appearance of the outlet opening and discharge control of the cup lid shown in Figure 4.

[0063] Referring to FIG. 5, for example, when the discharge amount control knob (370) is turned all the way in one direction, the discharge valve (360) rotates in response to the rotation of the discharge amount control knob (370), so that the third hole (362) of the discharge valve (360) does not overlap with the first hole (351) of the discharge port (350), and furthermore, an O-ring (not shown) at the top of the discharge valve (360) seals the inlet of the discharge port (350), so that the discharge port (350) is completely sealed. Through this, the beverage concentrate contained inside the receiving space (340) of the cup lid (300) is not discharged downward.

[0064] If the discharge amount control knob (370) is turned in the opposite direction, the discharge valve (360) rotates in the opposite direction in response to the rotation of the discharge amount control knob (370), and the third hole (362) of the discharge valve (360) begins to overlap with the first hole (351) of the discharge port (350) to some extent, and a passage for the beverage concentrate to flow through the discharge valve (360) and the discharge port (350) is formed through this overlapping space. Through this, the beverage concentrate contained inside the receiving space (340) of the cup lid (300) is discharged little by little downward. If the discharge amount control knob (370) is rotated a little more, the size by which the third hole (362) of the discharge valve (360) overlaps with the first hole (351) of the discharge port (350) becomes larger, and the amount of the beverage concentrate flowing out into the lower cup through the discharge port (350) can increase.

[0065] That is, by rotating the discharge control knob (370), it is possible to prevent the beverage concentrate from flowing down the discharge port (350) and to control the amount of the beverage concentrate flowing into the cup below through the discharge port (350) per hour.

[0066] Figure 6 shows a cross-sectional view of a cup lid according to another embodiment of the present invention.

[0067] Figure 7 shows the appearance of the outlet opening and discharge control of the cup lid shown in Figure 6.

[0068] In another embodiment of the present invention illustrated in FIG. 6, another cup lid (400) has a similar shape to the cup lid (300) illustrated in FIG. 4, but only the shapes of the discharge port (450) and the discharge valve (460) are different.

[0069] The discharge port (450) illustrated in FIG. 7 is formed from a bottom surface inside the receiving space (440) to the lower surface of the lid body (410), and a passage is formed through which the beverage concentrate can fall through a first hole (451) formed in an area of ​​the lower surface that is off the center of the lower surface. In addition, the discharge valve (460) illustrated in FIG. 4 is formed to correspond to the internal shape of the discharge port (450) so as to be able to seal the discharge port (450), and an internal passage is formed inside the discharge valve (460) so as to allow the beverage concentrate contained inside the receiving space (440) to be discharged downwardly to the outside of the cup lid (400), and the internal passage is characterized in that it is formed from a second hole (461) formed in an area of ​​the upper surface or the upper side surface to a third hole (462) formed in an area of ​​the lower surface that is off the center of the lower surface but is formed in correspondence to the arrangement position of the first hole (451).

[0070] Referring to FIG. 7, in accordance with another embodiment of the present invention, when the discharge volume control handle (470) is turned all the way in one direction, the discharge valve (460) rotates in response to the rotation of the discharge volume control handle (470), so that the third hole (462) formed at the bottom of the discharge valve (460) rotates so that it does not overlap with the first hole (451) formed at the bottom of the discharge port (450), and furthermore, an O-ring (not shown) at the top of the discharge valve (460) seals the inlet of the discharge port (450), so that the discharge port (450) is completely sealed. In this case, since the first hole (451) and the third hole (362) are formed not at the center of the circular bottom surface but rather offset to one side, the rotation of the discharge valve (460) can prevent the third hole (362) from overlapping with the first hole (451). Through this, the beverage concentrate contained inside the cup lid (400) receiving space (440) is not discharged downward.

[0071] If the discharge amount control knob (470) is turned in the opposite direction, the discharge valve (460) rotates in the opposite direction in response to the rotation of the discharge amount control knob (470), and the third hole (462) formed on the bottom surface of the discharge valve (460) begins to overlap with the first hole (451) of the discharge port (450) to a certain extent, and a passage for the beverage concentrate to move through the discharge valve (460) and the discharge port (450) is formed through this overlapping space. In this case as well, the formation position of the third hole (462) is formed away from the center of the lower surface of the discharge valve (460), but is formed at a position corresponding to the arrangement position of the first hole (451), so that they can overlap in accordance with the rotation of the discharge valve (460).

[0072] Through this, the beverage concentrate contained inside the cup lid (400) receiving space (440) is discharged little by little downward. If the discharge amount control handle (470) is rotated a little more, the size by which the third hole (462) of the discharge valve (460) overlaps the first hole (451) of the discharge port (450) becomes larger, and the amount of beverage concentrate flowing out into the lower cup through the discharge port (450) can increase.

[0073] That is, by rotating the discharge control knob (470), it is possible to prevent the beverage concentrate from flowing down the discharge port (450) and to control the amount of the beverage concentrate flowing into the cup below through the discharge port (450) per hour.

[0074] Figure 8 shows a cross-sectional view of a cup lid according to another embodiment of the present invention.

[0075] Referring to FIG. 8, a cup lid (500) according to one embodiment of the present invention includes a lid body (510), a beverage concentrate inlet (520), an inlet stopper (530), a receiving space (540), a discharge outlet (550), a discharge valve (560), and an exhaust volume control handle (570).

[0076] A cup lid (500) is a lid for a beverage cup, such as a tumbler, that can hold a beverage. It may be made of transparent plastic material or may be made of plastic material of a different color. In addition, if the cup lid is a tumbler lid, it may be made by combining a plastic material part with a metal or ceramic material.

[0077] The lid body (510) of the cup lid (500) has a space (540) formed therein that can accommodate a beverage concentrate, and covers the upper part of the beverage cup to protect the beverage contained in the cup.

[0078] The beverage concentrate injection port (520) is formed in the form of a hole on a portion of the upper surface of the lid body (510) and serves to connect the exterior of the lid body (510) to the interior of the receiving space (540). In addition, the injection port stopper (530) serves to open and close the beverage concentrate injection port (520).

[0079] The discharge port (550) is formed by extending from one bottom surface inside the receiving space to the bottom surface of the lid body (510). The discharge port (550) functions as a passage through which the beverage concentrate contained inside the receiving space (540) can be discharged to the outside of the cup lid in the downward direction of the cup lid (500). The bottom surface of the discharge port (550) is blocked, and a step exists between the bottom surface and the bottom surface of the lid body (510), and a hole (551) is formed in a portion of the step surface. That is, the discharge port (550) is formed by extending from one bottom surface inside the receiving space (540) to the bottom surface of the lid body, but the bottom surface is blocked, and a passage through which the beverage concentrate can fall is formed through the first hole (551) formed on one side of the upper portion of the bottom surface. Meanwhile, it is preferable that the bottom surface inside the receiving space be formed to be slightly inclined so that the discharge port (550) is located at the lowest surface.

[0080] The discharge valve (560) is a valve formed in a shape corresponding to the internal shape of the discharge port (550). The discharge valve (560) functions as a valve capable of sealing the discharge port (550) and, if necessary, partially opens the passage of the discharge port (550) so that the beverage concentrate can be discharged through the discharge port (550). That is, the discharge valve (560) is formed to correspond to the internal shape of the discharge port (550) so as to seal the discharge port (550), and a passage is formed through a groove (561) formed in the vertical longitudinal direction on the side thereof so that the beverage concentrate contained within the receiving space (540) can be discharged downwardly to the outside of the cup lid (500).

[0081] The discharge control handle (570) is formed on the outside of the lid body (510) and is directly or indirectly connected to the discharge valve (560) to rotate the discharge valve (560), thereby controlling the discharge amount by adjusting the sealing between the discharge valve (560) and the discharge port (550) and the size of the overlap between the first hole (551) and the side groove (561). Accordingly, the discharge control handle (570) functions to control the amount of beverage concentrate contained in the receiving space (540) that flows out through the groove (561) formed on the side of the discharge valve (560) into the space where the first hole (351) of the discharge port (350) and the side groove (561) overlap.

[0082] For this purpose, the discharge valve (560) includes an O-ring (not shown) for sealing between the discharge port (550) and the discharge valve (560) when the discharge valve (560) is tightened below a predetermined height in at least one area.

[0083] Figure 9 shows the appearance of the discharge port opening and discharge control of the cup lid shown in Figure 8.

[0084] Referring to FIG. 9, for example, when the discharge amount control knob (570) is turned all the way in one direction, the discharge valve (560) rotates in response to the rotation of the discharge amount control knob (570), so that the side groove (561) of the discharge valve (560) rotates so as not to overlap the first hole (551) of the discharge port (550), and furthermore, an O-ring (not shown) at the top of the discharge valve (560) seals the inlet of the discharge port (550), so that the discharge port (550) is completely sealed. Through this, the beverage concentrate contained inside the receiving space (540) of the cup lid (500) is not discharged downward.

[0085] If the discharge amount control knob (570) is turned in the opposite direction, the discharge valve (560) rotates in the opposite direction in response to the rotation of the discharge amount control knob (570), and the side groove (561) of the discharge valve (560) begins to overlap with the first hole (551) of the discharge port (550) to a certain extent, and a passage for the beverage concentrate to flow through the discharge valve (560) and the discharge port (550) is formed through this overlapping space. Through this, the beverage concentrate contained inside the receiving space (540) of the cup lid (500) is discharged little by little downward. If the discharge amount control knob (570) is rotated a little more, the size by which the side groove (561) of the discharge valve (560) overlaps with the first hole (551) of the discharge port (550) becomes larger, and the amount of the beverage concentrate flowing out into the lower cup through the discharge port (550) can increase.

[0086] That is, by rotating the discharge control knob (570), it is possible to prevent the beverage concentrate from flowing down the discharge port (550) and to control the amount of the beverage concentrate flowing into the cup below through the discharge port (550) per hour.

[0087] In this way, by using the cup lid according to the present invention, the first high-concentration concentrate contained in the cup and the second high-concentration concentrate contained in the cup lid are separately contained, and the second high-concentration concentrate is slowly dropped into the cup by the user through the control handle attached to the cup lid, so that even if the ice inside the cup melts, the user can drink a beverage of a constant concentration due to the high-concentration concentrate being slowly added.

[0088] In addition, by using the cup lid according to the present invention, the user can control the control valve according to his / her choice in response to various beverage consumption times, such as fast drinking and slow drinking, thereby controlling the discharge amount of the high-concentration concentrate contained in the cup lid, so that the user can drink a beverage of a constant concentration even if the beverage consumption time of the user varies.

[0089] Although the present invention has been described above with specific details such as specific components and limited examples and drawings, these are provided only to help a more general understanding of the present invention, and the present invention is not limited to the above examples, and those with ordinary knowledge in the technical field to which the present invention pertains can make various modifications and variations from this description.

[0090] Therefore, the idea of ​​the present invention should not be limited to the embodiments described above, and all things that are modified equally or equivalently to the following claims as well as the claims are considered to fall within the scope of the idea of ​​the present invention.

[0091] A cup lid that can maintain a constant beverage concentration can be applied to various cups for drinking coffee, tea, etc.
