Description

[Technical Field]

[0001] The present invention relates to a functional disposable cup lid, and more particularly to a cup lid that can maintain a constant concentration of drinks such as iced coffee. [Background technology]

[0002] Generally, when pouring iced coffee or the like into a disposable cup, a typical cup lid 100 such as that shown in FIG. 1 is used.

[0003] The conventional disposable cup lid 100 shown in FIG. 1 is generally a plastic disposable cup lid in a transparent, white, or black color, and is fixed to the cup via a fixing protrusion on the underside, and has a hemispherical or flat shape.

[0004] Generally, when pouring cold drinks like iced coffee, a hemispherical transparent cup lid is used, and when pouring hot drinks, a flat white or black disposable cup lid is used. Generally, the cup lid has a hole in the center so that a straw can be inserted, as shown in Figure 1.

[0005] Additionally, iced coffee is typically served in a cup with ice, a small amount of water, and a strong espresso. In this case, the coffee is initially very strong because of the small amount of water, but as time passes, the ice melts and turns to water, gradually diluting the coffee's strength. In this case, when you first drink the coffee, you will drink a very strong coffee, but gradually it will become weaker. This creates a problem in that if you drink the coffee slowly, you will end up drinking mostly watery coffee. Summary of the Invention [Problem to be solved by the invention]

[0006] An object of the present invention is to solve all of the above-mentioned problems.

[0007] An object of the present invention is to provide a cup lid that can provide iced drinks with a consistent concentration.

[0008] Another object of the present invention is to provide a cup lid that can be impregnated with drink concentrate to create a unique pattern or display a specific logo.

[0009] Another object of the present invention is to provide a cup lid that can adjust the amount of drink concentrate that leaks out, taking into account the time it takes to drink the drink, and that can maintain the concentration and indicate the remaining amount of drink that can be drunk and the remaining time. [Means for solving the problem]

[0010] According to one embodiment of the present invention, a cup lid for a drinking cup into which a drink can be poured includes a body portion that can be coupled to the cup so as to cover the top of the drinking cup, and a container portion that is formed on the underside of the body portion facing at least a portion of the surface of the body portion, at least a portion of its end being connected to the body portion to form a space inside which a liquid can be contained, and that includes an inlet at an upper end through which a liquid can be poured, and one or more leak holes at a lower end through which the liquid can leak using gravity. [Effects of the Invention]

[0011] When using the cup lid of the present invention, the first high-concentration concentrate placed in the cup and the second high-concentration concentrate placed in the cup lid are placed separately, and the second high-concentration concentrate flows slowly into the cup, so that even if the ice inside the cup melts, you can drink a drink of the desired concentration thanks to the high-concentration concentrate that is slowly added.

[0012] In addition, by using the cup lid of the present invention, when a concentrated drink is served, a specific trademark logo or beautiful pattern can be displayed on the outside of the cup lid, thereby increasing the advertising effect and aesthetic appeal.

[0013] Furthermore, by using the cup lid of the present invention, it is possible to indicate the remaining time and amount of concentrated liquid remaining until all of the remaining liquid leaks out after starting to drink the drink, allowing the user to gauge how long they can drink a drink of a certain concentration.

[0034] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily practice the present invention.

[0035] FIG. 2 shows a cross-sectional view of a cup lid according to one embodiment of the present invention.

[0036] 2, a cup lid 200 according to one embodiment of the present invention includes a body portion 201 that can be coupled to a drinking cup to cover the top of the cup, and a container portion 202 that is formed below the body portion 201 facing at least a portion of the surface (upper surface 211) of the body portion 201, with a portion of its end connected to the body portion 201 to form a space capable of containing liquid therein, and that includes an inlet 213 at its upper end through which liquid can be poured, and one or more leak holes 214 at its lower end through which liquid can leak out by gravity. The cup lid 200 may be made of a transparent plastic material or a plastic material of another color. If the cup lid is not disposable, it may be made of a metal material or a ceramic material.

[0037] Meanwhile, the receiving body 202 shares at least a portion of the surface of the body 201 as an upper surface 211 of the receiving body 202, and includes a lower surface 212 facing the upper surface 211 to form one liquid receiving space.

[0038] In addition, the inlet 213 of the container 202 is formed so that a liquid such as coffee concentrate can be injected into the container in a region of the upper surface or in a region where the upper and lower surfaces join.

[0039] The body portion 201 may further include a body portion hole 215 through which a beverage can be drunk or a straw can be inserted, a rim portion 216 formed by protruding outward from below the lower end of the cup lid 200, and a fixing portion 217 that can be attached to the upper edge of the cup below the rim portion 216.

[0040] 2, a cup lid 200 according to an embodiment of the present invention is characterized in that it has a container 202 formed below the body 201, into which coffee concentrate can be poured. The container 202 may be formed over the entire underside of the body 201, or may be formed in a partial area of ​​the underside of the body 201. When the container 202 is formed over the entire underside of the body 201, it may be formed in a donut shape with the body hole 215 as the center. When the container 202 is formed over only a partial area of ​​the underside of the body 201, it may be formed in a rectangular, oval, or any other shape desired by the manufacturer.

[0041] The container 202 is formed by connecting an upper surface 211, which is shared with at least a portion of the body 201, and a lower surface 212, which faces the upper surface 211, at its end. The upper surface 211 and the lower surface 212 may be connected over the entire area, or may be separated in some areas and not connected, forming an inlet 213 and a water leakage structure 214. If the upper surface 211 and the lower surface 212 are connected over the entire area, it is preferable that the inlet 213 and the water leakage hole 214 are formed in the upper surface 211 and the lower surface 212, respectively.

[0042] Meanwhile, as described above, an inlet 213 through which a liquid can be injected is formed at the upper end of the container 202. The inlet 213 may be formed below the body hole 215, or may be formed as an independent hole in a region of the upper surface 211, independent of the body hole 215.

[0043] When the inlet 213 is formed below the body hole 215, the upper surface 211 and the lower surface 212 may be open and not connected to each other below the body hole 215. Espresso coffee concentrate can be poured through the inlet 213.

[0044] In addition, it is preferable that the water leakage holes 214 have holes of different sizes so that liquids such as coffee concentrate contained in the receptacle part 202 can flow at different speeds. In this case, all of the water leakage holes 214 are blocked before the coffee concentrate is poured into the receptacle part 202, and after the coffee concentrate is poured, the water leakage holes 214 can be formed and used at a desired size. In order to block the water leakage holes, each water leakage hole 214 includes a water leakage hole membrane that is at least partially connected to the lower surface and has a size corresponding to the water leakage hole, and a water leakage hole boundary portion that is formed between the lower surface and the water leakage hole membrane and has a thickness thinner than the lower surface and the water leakage hole membrane.

[0045] FIG. 3 shows the shape of a water leakage hole according to one embodiment of the present invention.

[0046] As shown in FIG. 3 , the leak holes 214 include leak holes 214_a, 214_b, and 214_c of different sizes. Each leak hole is preferably blocked during product manufacture and sales, and is therefore composed of a leak hole membrane 311 and a leak hole boundary portion 312. The leak hole membrane 311 is typically manufactured to a size and shape that matches the size of each leak hole and is made of the same material and thickness as the lower surface 212. However, the leak hole boundary portion 312 is preferably thin so that the leak hole membrane 311 can be easily pierced with an iron needle or the like. The leak hole membrane 311 is preferably connected to the lower surface 212 via a connecting portion 313 to prevent the leak hole membrane 311 from falling into the cup and mixing with the drink when separated.

[0047] A method of using the cup lid 200 according to the present invention will be described below with reference to FIGS.

[0048] First, when serving an iced drink such as an iced Americano, ice, a small amount of water, and espresso coffee are placed in a cup. When serving iced coffee in this way, the coffee is initially very strong, but over time, it becomes too weak. Therefore, in the present invention, additional espresso coffee is poured into the container portion 202 of the cup lid 200. That is, when using the cup lid 200 according to the present invention, the espresso coffee initially poured into the cup is divided into two portions: one portion is poured into the cup and the other portion is poured into the container portion 202. Then, depending on the time it takes to drink the coffee, a hole is opened in one of the membranes of the multiple water leak holes 214, allowing the espresso coffee entering the container portion 202 to drip into the coffee. Therefore, even as the ice melts over time, the strength of the coffee can be maintained constant thanks to the additional espresso coffee.

[0049] FIG. 4 shows a cup lid according to another embodiment of the present invention.

[0050] 4, a cup lid 400 according to another embodiment of the present invention is substantially identical to the cup lid 200 of FIG. 2, differing only in the shape of the upper surface 201. The cup lid 400 of FIG. 4 has a substantially flat upper surface rather than a hemispherical one, with only the peripheral edge portion projecting. In this case, the container 202 has an upper surface 211 that corresponds to the peripheral surface of the cup lid 400, and a lower surface 212 formed below the upper surface 211. The container 202 is formed in a donut shape along the peripheral edge of the cup lid 400. The injection port 213 of the container 202 is formed in a portion of the upper end of the peripheral edge of the cup lid 400, and the body hole 215 is formed to avoid the upper surface 212, which is the area where the container 202 is formed. In this case, it is preferable that the upper surface 211 area of ​​the body 201, which is shared with the container 202, is projected more than other areas.

[0051] FIG. 5 shows a cup lid according to yet another embodiment of the present invention.

[0052] 5, in a cup lid 500 according to another embodiment of the present invention, the container 202 is formed in a spiral shape from a body hole 215 to the end of the body while rotating around the center of the body. In this case, an inlet 213 is formed at the center of the spiral or adjacent to the body hole 215, and a water leak hole 214 is formed at the end of the spiral.

[0053] In this way, not only can the remaining amount of liquid such as coffee concentrate held in the container portion 202 be visually and easily grasped, but also the liquid held in the container portion can produce a visually beautiful pattern.

[0054] FIG. 6 shows a cup lid according to an embodiment of the present invention.

[0055] Referring to FIG. 6, at least a portion of the upper surface 211 of the container portion 202 of a cup lid 600 according to yet another embodiment of the present invention includes a pattern 601 configured in an uneven shape so as to display a specific logo.

[0056] In this case, since the liquid in the container 202, for example, espresso coffee, is not transparent, when the espresso coffee is poured into the container 202, the logo such as the coffee brand can be clearly seen, maximizing the advertising effect.

[0057] FIG. 7 shows a cup lid according to yet another embodiment of the present invention.

[0058] As shown in FIG. 7, a cup lid 700 according to another embodiment of the present invention further includes a display 701 on the upper surface 211 of the container portion, which displays an approximate remaining time or remaining amount until the liquid completely flows out through the leak hole.

[0059] For example, the display unit 701 may be displayed differently depending on the size of the leak hole 214, and may display the approximate remaining time, i.e., the number of minutes until the remaining liquid in the container 202 is completely leaked out. Also, the display unit 701 may be displayed as a remaining percentage, which may indicate the approximate amount of liquid remaining.

[0060] This allows the person drinking iced coffee to know how many minutes it will take to drink coffee of a certain strength and how many minutes it will take for all the coffee inside the container 202 to fall into the coffee cup, and allows them to drink coffee of a certain strength at ease.

[0061] The present invention has been described above in accordance with specific details such as specific components and limited embodiments and drawings, but this is provided to facilitate a more general understanding of the present invention, and the present invention is not limited to the above embodiments. Those skilled in the art will be able to make various modifications and variations from such descriptions.

[0062] Therefore, the spirit of the present invention should not be limited to the above-described embodiments, but should include not only the claims described below, but also all modifications equivalent to or similar to the claims, which fall within the scope of the spirit of the present invention.
