A drink cup that allows liquid to be poured out in a concentrated manner.

Abstract

We provide a drink cup that allows liquid to be dispensed in a concentrated manner. [Solution] The drink cup includes a cup body 10 and an inner circumferential flange 20 formed on the inner wall surface of the cup body, provided along the rim 11, and having at least one notched groove 21. When a user drinks the liquid in the drink cup, the liquid in the cup body is blocked by the inner circumferential flange and flows out in a concentrated manner from the notched groove located below, allowing it to flow smoothly into the user's mouth, effectively preventing the liquid from overflowing from the user's mouth. Furthermore, since the inner circumferential flange is formed on the inner wall surface of the cup body, it does not interfere with the user holding the rim of the cup body in their mouth. In addition, by using it in combination with a cup lid assembly that seals the cup body, the drink cup can also be given functions for keeping the drink warm and brewing.

Description

Technical Field

[0001] The present invention relates to a drink cup, and more particularly to a drink cup that can allow liquid to flow out intensively and avoid overflow.

Background Art

[0002] A cup is mainly a container for containing beverages such as water, coffee, milk, juice, etc. A drinker can pour the desired beverage into the cup and drink it later. Conventional cups mainly have a cup body with an open top and a rim surrounding the opening, and the bottom of the cup body is sealed so that beverages can be contained inside the cup body. When drinking, the drink cup is lifted, the rim is held by the mouth, and the cup body is tilted so that the internal beverage flows into the mouth from the rim for drinking.

[0003] However, in the prior art, since the rims of most cups are formed in a smooth arc shape, a drinker needs to appropriately adjust the tilt angle of the cup body at any time according to the amount of beverage in the cup body during drinking, and keep the width of the beverage flowing over the rim within a range smaller than the width of the drinker's mouth. Thereby, the beverage in the cup body can flow smoothly into the drinker's mouth. However, if the tilt angle becomes too large, the width of the beverage flowing over the rim will instantaneously expand beyond the width of the drinker's mouth. As a result, the beverage will overflow from the drinker's mouth and spill onto the drinker's clothes and the surrounding table or floor.

[0004] In order to solve the problem that the outflow width expands due to the tilt angle becoming too large as described above, in the prior art, there are also cups with pouring mouths formed on the rims. Such a pouring mouth protrudes outward from the cup body and can concentrate the liquid into a single thin stream, enabling accurate pouring into the target container. However, a spout that protrudes outward from the cup body is not suitable for the drinker to drink directly from. Therefore, cups with spouts are generally used as measuring cups or for liquid pre-treatment, and the liquid contained in the cup is dispensed into other cups via the spout in subsequent processes; they are not intended for direct consumption by the drinker. Furthermore, when a cup with a spout is fitted with a lid, it is often difficult to completely cover the spout as well, resulting in problems with dustproofing and heat retention. [Overview of the project]

[0005] The purpose of this invention is to provide a drink cup that can prevent overflow during drinking by concentrating and flowing the contained liquid within a certain area, in view of the problems present in the prior art described above.

[0006] To achieve the above objective, this invention provides: A cup body having an opening at the top and a sealed bottom, with a rim surrounding the opening, We propose a drink cup that allows liquid to flow out in a concentrated manner, characterized by including an inner circumferential flange formed to protrude from the inner wall surface of the cup body, provided along the rim, and having at least one notched groove formed therein.

[0007] With the structure described above, when a user lifts the drink cup and tilts the cup body so that one of the notched grooves is positioned downwards, the liquid inside the cup body is blocked by the inner flange and flows out in a concentrated manner from the lower notched groove, allowing it to flow smoothly into the user's mouth, thus effectively preventing the liquid from overflowing from the user's mouth. Furthermore, since the inner circumferential flange is formed on the inner wall surface of the cup body, it does not interfere with the user when they put the rim of the cup body in their mouth. Furthermore, by using the cup lid assembly, which seals the cup body, in conjunction with the drink cup, it is possible to give the drink cup functions for keeping drinks warm and for brewing.

[0009] As shown in Figure 1, the first embodiment of the present invention, a drink cup capable of concentrated liquid flow, includes a cup body 10, an inner flange 20, and a handle 30.

[0010] As shown in Figures 1 and 3, the cup body 10 has an upper opening at the top and a sealed bottom, so it can hold liquid inside. Furthermore, the cup body 10 has a rim portion 11 that surrounds the upper opening.

[0011] The inner circumferential flange 20 is formed to protrude from the inner wall surface of the cup body 10, is provided along the rim portion 11, and has at least one notched groove 21 formed therein. In this invention, notched grooves 21 are provided on both opposing sides of the rim portion 11, but the invention is not limited to this, and for example, there may be only one notched groove 21, or there may be two or more.

[0012] At least one end of the handle 30 is fixed to the outer wall surface of the cup body 10. In this invention, the handle 30 is curved, and both ends of the handle 30 extend in the same direction, and are fixed to the outer wall surface of the cup body 10. This allows the user to lift the drink cup by holding the handle 30.

[0013] As described above, according to the configuration shown in Figure 2, when a user lifts the drink cup and tilts the cup body 10 so that one of the notched grooves 21 is positioned downwards, the liquid 40 flowing towards the rim 11 inside the cup body 10 is blocked by the inner flange 20 and flows out in a concentrated manner from the notched groove 21 located downwards.

[0014] Furthermore, as shown in Figure 4, the angle θ between the handle 30 and the respective notched grooves 21 of the inner flange 20 is preferably approximately 90 degrees. This ensures that when the user holds the handle 30 with their hand to lift the drink cup, the notched groove 21 is positioned precisely at the user's mouth, allowing them to drink directly from the cup.

[0015] As shown in Figure 3, in this invention, the bottom of the cup body 10 is sealed by a bottom plate 12 which has an outer peripheral protrusion 13 on its outer surface. With this configuration, not only can the drink cup be stably placed on a flat surface by the outer peripheral convex portion 13, but also by separating the cup body 10 from the flat surface, the heat conduction between the cup body 10 and the flat surface can be reduced. Also, the user can prevent burns by lifting the drink cup by pressing fingers against the mouth rim portion 11 and the outer peripheral convex portion 13, but it is not limited to this, and the outer peripheral convex portion 13 may not be provided at the bottom of the cup body 10.

[0016] In the drink cup capable of concentrating the outflow of liquid according to the second embodiment of the present invention shown in FIG. 5, since no handle is provided on the outer wall surface of the cup body 10A, the user can lift the drink cup by directly gripping the cup body 10A, or can also lift the drink cup by pressing fingers against the mouth rim portion 11A and the outer peripheral convex portion 13A.

[0017] In the drink cup capable of concentrating the outflow of liquid according to the third embodiment of the present invention shown in FIGS. 6 and 7, the structure of the cup body 10B is the same as that of the cup body 10 of the drink cup according to the first embodiment described above, but the cup body 10B further includes a cup lid assembly 50B that is fixed to the top so as to cover the top and includes a cup lid 51B, a seal ring 52B, and a filter receiver 53B.

[0018] In the embodiment shown in FIG. 9, the top of the cup lid 51B is sealed, the bottom is formed as a downward opening, and it has an annular side wall 511B, an annular convex portion 512B, at least one positioning convex portion 513B, and an inner positioning annular groove 514B. The annular side wall 511B has a lower end surface surrounding the downward opening of the cup lid 51B. The annular convex portion 512B projects axially of the cup lid 51B from the lower end surface of the annular side wall 511B. At least one positioning convex portion 513B is provided at the edge of the annular convex portion 512B and projects outward of the cup lid 51B along the radial direction of the cup lid 51B, and an inner positioning annular groove 514B is provided on the inner wall surface of the annular side wall 511B.

[0019] The seal ring 52B is provided on the lower end surface of the annular side wall 511B of the cup lid 51B and surrounds the annular convex portion 512B.

[0020] The filter receiver 53B is for accommodating extraction materials such as tea leaves, coffee powder, and Chinese herbal medicines, and is detachably provided on the cup lid 51B. The filter receiver 53B has a housing portion 531B in which a housing space is formed, an upper opening and a plurality of filtering holes 532B are formed, and at least one engaging convex portion 533B formed on the upper end edge of the housing portion 531B and detachably engaged with the inner positioning annular groove 514B of the cup lid 51B.

[0021] As shown in FIG. 9, when attaching the filter receiver 53B to the cup lid 51B, until the engaging convex portion 533B of the filter receiver 53B engages with the inner positioning annular groove 514B of the cup lid 51B, the upper opening of the housing portion 531B of the filter receiver 53B is moved into the cup lid 51B toward the cup lid 51B, thereby connecting and positioning the filter receiver 53B and the cup lid 51B. In the present invention, at least one engaging convex portion 533B includes a plurality of engaging convex portions 533B, and these engaging convex portions 533B are provided on the upper end edge of the housing portion 531B so as to surround the housing portion 531B at intervals, but it is not limited thereto. The engaging convex portion 533B may be one, and this engaging convex portion 533B is provided on the upper end edge of the housing portion 531B so as to surround the housing portion 531B, as long as it can be stably engaged with the inner positioning annular groove 514B of the cup lid 51B.

[0022] As shown in FIG. 8, when connecting the cup lid 51B and the top of the cup body 10B, first, align the positioning convex portion 513B of the cup lid 51B with the notch groove 21B of the inner peripheral flange 20B in the cup body 10B, move the positioning convex portion 513B downward through the notch groove 21B below the inner peripheral flange 20B, and then rotate the cup lid 51B to engage the positioning convex portion 513B and the inner peripheral flange 20B with each other. As shown in Figure 9, at this time, the annular projection 512B of the cup lid 51B is located inside the inner flange 20B of the cup body 10B, and the lower end surface of the annular side wall 511B of the cup lid 51B faces the rim 11B of the cup body 10B. As a result, the seal ring 52B is pressed against and clamped between the annular side wall 511B of the cup lid 51B and the rim 11B of the cup body 10B, thus sealing the space between the cup body 10B and the cup lid 51B.

[0023] According to the third embodiment of the present invention shown in Figure 9, the user pours hot water 61B into the cup body 10B, places the extracting material 62B into the filter holder 53B, attaches the filter holder 53B to the cup lid 51B, and then places the cup lid 51B over the top of the cup body 10B to seal it. Next, as shown in Figure 10, when the drink cup is inverted, the hot water 61B flows in and immerses the extractant 62B, thereby extracting the flavor, aroma, and nutrients of the extractant 62B. After a predetermined time has elapsed, the drink cup is placed upright, and the cup lid 51B is rotated and removed from the cup body 10B along with the filter holder 53B, allowing the user to enjoy the brewed drink.

[0024] Furthermore, as shown in Figure 11, when using this invention, the filter holder 53B may be removed from the cup lid 51B, and only the cup lid 51B may be fitted onto the cup body 10B to maintain the temperature inside the drink cup.

[0025] Furthermore, in the fourth embodiment of the present invention, as shown in Figures 12 to 14, a drink cup capable of concentrated liquid flow is provided, with the cup body 10C having an elongated shape and a cup lid assembly 50C provided at the top. The cup lid assembly 50C includes a cup lid 51C, a sealing ring 52C, and a stopper lid 54C.

[0026] The structure of the cup lid 51C is substantially the same as that of the cup lid 51B of the third embodiment described above. The difference between the two is that the cup lid 51C of the fourth embodiment has an additional through-hole 515C formed through its top.

[0027] The seal ring 52C, like the cup lid 51B in the third embodiment described above, is provided on the lower end surface of the annular side wall 511C of the cup lid 51C and surrounds the annular protrusion 512C. Therefore, when the cup lid 51C is attached to the top of the cup body 10C, the seal ring 52C is pressed against and clamped between the cup lid 51C and the cup body 10C, thereby sealing the space between the cup lid 51C and the cup body 10C.

[0028] The stopper cap 54C is fixed to the through hole 515C of the cup lid 51C and is tubular in shape. The top surface of the stopper cap 54C is provided with a plurality of lid pieces 541C that are separated from each other and arranged in an annular shape. When the straw 71C is inserted into the stopper cap 54C, the plurality of lid pieces 541C are pressed against the straw 71C and bend inward, allowing the straw 71C to enter the cup body 10C further.

[0029] In the drink cup of this invention, the inner circumferential flanges 20 and 20B formed on the inner wall surfaces of the cup bodies 10, 10A, 10B, and 10C do not obstruct the user from putting the rim portions 11, 11A, and 11B of the cup bodies 10, 10A, 10B, and 10C to their mouths. Furthermore, the liquid 40 flowing from the inside of the cup bodies 10, 10A, 10B, and 10C toward the rim portions 11, 11A, and 11B is concentrated and discharged from the notched grooves 21 and 21B located below, allowing it to flow smoothly into the user's mouth, thus effectively preventing the liquid 40 from overflowing from the user's mouth. Furthermore, since the inner circumferential flanges 20 and 20B, which have notched grooves 21 and 21B formed on them, are formed on the inside of the cup bodies 10, 10A, 10B, and 10C, the drink cup of this invention can be given functions for heat retention and brewing by being used in conjunction with the cup lid assemblies 50B and 50C that seal the cup bodies 10, 10A, 10B, and 10C.
