Claims (9)

  1. A cup lid (200) for a beverage cup capable of containing a beverage therein, the cup lid comprising: a body (201) coupled to the beverage cup so as to cover a top of the beverage cup; and a receiving portion (202) disposed under the body and facing at least a partial surface (211) of the body, wherein at least a portion of an end of the receiving portion is connected to the body to form a space therebetween capable of containing coffee concentrate therein, characterized in that an injection hole (213) through which the coffee concentrate may be input into the space is formed in an upper end of the receiving portion, in that one or more leak holes (214) through which the coffee concentrate may leak into the cup under gravity are formed in a lower end of the receiving portion, in that the receiving portion is composed of an upper surface (211) as at least a partial surface of the body, and a lower surface (212) facing the upper surface, in that the injection hole through which the coffee concentrate may be input into the space of the receiving portion is formed in one area of the upper surface of the receiving portion or at least in a portion of an area where the upper surface and the lower surface are bonded to each other, in that the coffee concentrate leaks through the one or more leak holes into the beverage cup drop by drop at a predetermined time interval, in that the receiving portion extends in a spiral manner from a body hole (215) positioned at a center of the body to an outer edge of the body, and in that the injection hole is formed at a beginning position of the spiral extension, and the one or more leak holes are formed at an end position of the spiral extension.
  2. The cup lid of claim 1, wherein a portion of the body as the upper surface (211) of the receiving portion protrudes from a remaining portion thereof, wherein the body hole (215) through which a straw may be inserted into the cup is formed in one area of the body.
  3. The cup lid of claim 1, wherein the body is formed in a hemispherical shape, and the body hole (215) through which a straw may be inserted into the cup is formed at a center of the body, wherein the receiving portion (202) is composed of the upper surface (211) as at least a partial surface of the body, and the lower surface (212) facing the upper surface, wherein the lower surface and the upper surface of the receiving portion are spaced from each other in at least a partial area around the body hole to form the injection hole (213) through which the coffee concentrate may be injected into the space of the receiving portion.
  4. The cup lid of claim 1, wherein the cup lid is made of a plastic material.
  5. The cup lid of claim 1, wherein each leak hole (214) includes: a leak hole film (311) having a size corresponding to a size of each leak hole and at least partially coupled to the lower surface so as to block the leak hole; and a leak hole boundary portion formed between the lower surface and the leak hole film and having a thickness smaller than a thickness of each of the lower surface and the leak hole film.
  6. The cup lid of claim 5, wherein each leak hole (214) further includes a connection portion formed between the lower surface and the leak hole film so as to connect the lower surface and the leak hole film to each other in at least partial area.
  7. The cup lid of claim 1, wherein the one or more leak holes (214) includes a plurality of leak holes having different diameters.
  8. The cup lid of claim 1, wherein the receiving portion (202) includes, in at least a portion of the upper surface (211), a concave-convex pattern (601) to display a specific logo.
  9. The cup lid of claim 1, wherein the receiving portion (202) further includes an indicator (701) indicating a rough remaining time or remaining amount until an entirety of the coffee concentrate flows through the one or more leak holes out of the space into the cup.

Description

[Technical Field] The present disclosure relates to a functional disposable cup lid. More specifically, the present disclosure relates to a cup lid capable of keeping a concentration of beverage such as iced coffee constant. [Background Art] In general, when iced coffee or the like is put in a disposable cup, a general cup lid 100 as shown in FIG. 1 is used. The conventional disposable cup lid 100 as shown in FIG. 1 generally is a plastic disposable cup lid of a transparent color, white, or black, and is fixed to a cup via a fixing protrusion at a bottom thereof, and has a hemispherical shape or a flat shape. Documents US 5035320A, WO 2019/114899, US2010/037780A1 and WO 2005/077780A1 disclose disposable cup lids comprising drink additive that may be released into a coffee cup. In general, a hemispherical transparent cup lid is used when cold beverage such as iced coffee is contained in the cup. A flat white or black disposable cup lid is used when hot beverage is contained in the cup. Further, like the cup lid in FIG. 1, it is common that the cup lid has a hole in a center thereof through a straw may be inserted. The iced coffee is usually produced by inputting ice, a small amount of water, and strong espresso coffee into a cup. In this case, an amount of water is small initially, so that the coffee becomes very thick, and as time goes by, the ice melts to become water, and thus the concentration of the coffee slowly becomes softer. In this case, the first time a user drinks coffee, the user will drink a very strong coffee, and gradually, will drink a light coffee. When the user drinks the coffee slowly, the user may drink only watery coffee at the end. [Disclosure] [Technical Problem] The present disclosure aims to solve all of the above problems. The present disclosure aims to provide a cup lid capable of keeping a concentration of ice beverage constant. In addition, the present disclosure aims to provide a cup lid capable of displaying a specific logo or creating a unique shape by including a beverage concentrate in the cup lid. In addition, the present disclosure aims to provide a cup lid capable of adjusting an amount of leakage of the beverage concentrate in view of a drinking time of the beverage, and maintaining the concentration to indicate a remaining amount and a drink remaining time of the beverage. [Technical Solution] According to one embodiment of the present disclosure, a cup lid for a beverage cup capable of containing a beverage therein includes a body coupled to the beverage cup so as to cover a top of the beverage cup; and a receiving portion disposed under the body and facing the at least a partial surface of the body, wherein at least a portion of an end of the receiving portion is connected to the body to form a space therebetween capable of containing coffee concentrate therein, wherein an injection hole through which the coffee concentrate is input into the space is formed in an upper end of the receiving portion, wherein one or more leak holes through which the coffee concentrate leaks into the cup under gravity are formed in an lower end of the receiving portion. [Advantageous Effects] When the cup lid according to the present disclosure is used, a first high-concentration concentrate is contained in the cup while a second high-concentration concentrate is contained in the cup lid, and then the second high-concentration concentrate slowly flows into the cup. Thus, as the ice inside the cup melts, the user may drink the beverage at a constant concentration as the high-concentration concentrate contained in the cup lid is added to the cup slowly. In addition, when the cup lid according to the present disclosure is used, a logo of a specific brand or a beautiful pattern may be displayed on the outside of the cup lid when the beverage concentrate is contained, thereby increasing advertising effects or aesthetics. In addition, when the cup lid according to the present disclosure is used, the user may know the remaining time or remaining amount until the entirety of the remaining concentrate is leaked from the start of drinking the beverage. Thus, the person who drinks the iced coffee may figure out a time duration for which he/she may drink the coffee at a constant concentration, and the remaining time until an entirety of the liquid flows out through the leak hole out of the receiving portion into the coffee cup. Thus, he/she may drink the coffee at the constant concentration leisurely.
