Description

beverage extraction device

[0001] The present invention relates to a beverage extraction device for extracting a beverage from a raw material. The raw material may be coffee beans, plant leaves, stems, roots, or fruits, or powder thereof.

[0002] People enjoy beverages like coffee and tea. Coffee is made by mixing coffee grounds with water, while tea is made by mixing water with the leaves, stems, roots, and / or fruits of various plants. However, when drinking these beverages, people only drink the extracted liquid, filtering out the raw materials, such as coffee grounds or the leaves and stems of the plants.

[0003] While there are several methods for brewing beverages, the relatively simple method of placing ingredients in a funnel-shaped filter and pouring water into it to extract the beverage is widely used. The filter can be made of a variety of materials, including paper, fabric, plastic, and metal.

[0004] One type of beverage extraction device sold on the market, the so-called dripper, has a problem in that it is difficult to control the concentration of the extracted beverage because the outlet located at the bottom of the funnel-shaped filter is always open.

[0005] Meanwhile, the clever dripper (product name) sold in many countries including the United States has an opening and closing function for the outlet, but it is inconvenient to use as water must be poured from outside the cup and then placed back on top of the cup, and it has a relatively complex structure, which makes it expensive to manufacture. In addition, if the cup that holds the beverage discharged from this dripper is opaque, it is difficult to check the amount of beverage being poured into the cup.

[0006] To address the above issues, the applicant has invented PCT International Application Publication No. WO 2023 / 018171 (Title: Beverage Extracting Device for Extracting Beverage from Raw Materials Contained in a Filter, hereinafter referred to as "Applicant's Invention"). However, "Applicant's Invention" was an initial invention idea that required further refinement to be developed into a commercially viable product.

[0007] An object of the present invention is to provide a beverage dispensing device having improved durability of a main body. Another object of the present invention is to provide a beverage dispensing device that, when dispensing a beverage contained in a receiving portion, directs the beverage toward a dispensing port so that the beverage is discharged relatively smoothly. Another object of the present invention is to provide a beverage dispensing device that prevents the beverage from leaking through a gap between the dispensing port and the closing portion when the dispensing port is in a closed position. Another object of the present invention is to provide a beverage dispensing device that can be supported on the upper portion of an arbitrary cup selected by a user even if the opening of the cup is larger than the outer diameter of the extended portion of the base portion. Another object of the present invention is to provide a beverage dispensing device that reduces the volume of the base portion and the main body when stored and is convenient to use.

[0008] In order to achieve the above object, the beverage dispensing device according to the present invention comprises a base part having a circular opening, a vertical penetration part penetrating vertically from an opening edge in contact with the opening, an extension part extending radially outward from the opening, a downward extension part extending downward from the opening edge at a position spaced apart from the vertical penetration part in a circumferential direction by a predetermined distance, a closing part extending radially inward from at least a portion of the downward extension part, and a rotational sliding guide part having an inclined part that slopes downward from the vertical penetration part toward the downward extension part in at least a portion of a circumferential section between the vertical penetration part and the downward extension part; A main body includes a funnel-shaped receiving portion having a bottom portion extending in the longitudinal direction, an insertion portion extending radially outward from a lower portion of the receiving portion and insertable into an opening of the base portion, a sliding projection portion protruding outward from the insertion portion and insertable into the vertical penetration portion, a support portion interconnecting the insertion portion and the receiving portion, and an outlet that is vertically penetrated from the bottom portion and is movable between a closed position in which the closing portion is closed by the closing portion when the sliding projection rotates in the circumferential direction toward the downward extension portion while being inserted into the vertical penetration portion, and an open position away from the closing portion when rotated in the opposite direction of the circumferential direction from the closed position.

[0009] Here, the bottom part has a convex portion protruding upward from the center, so that when discharging a beverage contained in the receiving portion, the beverage is directed toward the discharge port, thereby allowing the beverage to be discharged relatively smoothly.

[0010] And the above-mentioned closing part has a groove part dug to a predetermined depth in the plate surface, and the base part has an elastic member with relatively high elasticity inserted into the groove part, so that when the outlet is in the closed position, the beverage does not leak through the gap between the outlet and the closing part.

[0011] In addition, the above-mentioned extension is circular, and the base portion has a pair of support handles that protrude radially outwardly at different positions of the circular extension portion, so that any cup selected by the user can be supported on the upper portion of the cup even if the opening of the cup is larger than the outer diameter of the extension portion of the base portion.

[0012] And the above-mentioned receiving portion has a circular funnel opening having a larger diameter than the above-mentioned expansion portion and a pair of handle insertion grooves dug so that the pair of support handles can be inserted, thereby reducing the volume of the base portion and the main body during storage and making use convenient.

[0013] The beverage dispensing device according to the present invention has a body with excellent durability. Furthermore, when dispensing a beverage contained in a receiving portion, the beverage can be directed toward the outlet, thereby enabling relatively smooth dispensing. Furthermore, when the outlet is in the closed position, the beverage can be prevented from leaking through the gap between the outlet and the closed portion. Furthermore, even if the opening of any cup selected by the user is larger than the outer diameter of the extended portion of the base, the cup can be supported on the upper portion of the cup. Furthermore, the base portion and the body can be stored in a reduced volume, making them convenient to use.

[0024] Figures 12 and 13 are perspective views showing two examples of how the base part can be inserted into the funnel opening of the main body.

[0025] FIG. 14 and FIG. 15 are perspective views showing an elastic member spaced apart from a groove of a closing portion and an elastic member inserted into a groove of a closing portion according to another embodiment of the present invention.

[0026] Fig. 1 is a perspective view showing a beverage dispensing device according to the present invention placed on a cup (C), and Fig. 2 is an exploded perspective view. As shown in Figs. 1 and 2, the beverage dispensing device includes a base portion (100) placed on the upper portion of the cup (C), and a main body (300) detachably coupled to the base portion (100).

[0027] Fig. 3 is a perspective view of the main body (300) viewed from above, Fig. 4 is a perspective view of the main body (300) viewed from below, Fig. 5 is a top view of the main body (300), and Fig. 6 is a side cross-sectional view of the main body (300). As can be seen in Figs. 3 to 6, the main body (300) has a funnel-shaped receiving portion (310) having a circular funnel opening (315), a bottom portion (320) extending longitudinally from the lower portion of the receiving portion (310), and a pair of discharge ports (330) vertically penetrating through the bottom portion (320).

[0028] The longitudinal direction of the bottom portion (320) is the same as the line connecting a pair of discharge ports (330). The main body (300) has an discharge port edge surface (335) extending transversely with respect to the penetrating direction of the discharge port (330) with the discharge port (330) as the center from the lower portion of the discharge port (330). The bottom portion (310) has a convex portion (325) whose central portion gently protrudes upward. The pair of discharge ports (330) are arranged at positions spaced apart from each other by a predetermined distance on both sides with the convex portion (325) as the center.

[0029] The main body (300) has a circular insertion portion (350) that extends radially outward from the lower portion of the receiving portion (310). The insertion portion (350) has a ring shape with a peephole (353) that penetrates vertically. The user can visually check the beverage inside the cup (C) on which the lower portion of the base portion (100) is placed through the peephole (353) that is connected to the opening (110).

[0030] The main body (300) has a pair of sliding projections (351) that protrude radially outward from a portion of the outer circumference of the insertion portion (350). Each of the pair of sliding projections (351) is positioned perpendicular to the line connecting the pair of outlets (330) at the center of the line.

[0031] A separate funnel-shaped filter containing raw materials for extracting a beverage may be inserted into the receiving portion (310). The raw materials may be coffee grounds, and the filter may be made of a variety of materials, such as paper, fabric, plastic, or metal.

[0032] The main body (300) has a pair of support parts (340) that interconnect the insertion part (350) and the funnel-shaped receiving part (310) in the height direction. The support part (340) is located at the insertion part (350) closest to the sliding protrusion part (351). Therefore, the support part (340) can prevent the insertion part (350) and the sliding protrusion part (351) from being deformed in the height direction. In other words, the durability of the main body is enhanced.

[0033] Fig. 7 is a perspective view of the base portion (100) viewed from above, Fig. 8 is a perspective view of the base portion (100) viewed from below, and Fig. 9 is a bottom view of the base portion. As can be seen in Figs. 7 to 9, the base portion (100) has a circular opening (110) and an extension portion (130) extending radially outward from the opening (110).

[0034] The extension (130) has a pair of vertical penetration portions (135) that are opposed to each other and penetrate vertically at the opening edge (111) that contacts the opening (110). It is preferable that the pair of vertical penetration portions (135) face each other at 180-degree intervals with the opening as the center. Here, the opening (110) means a penetrated empty space, and the opening edge (111) means an edge of the opening (110), a peripheral portion of the opening (110), or a portion that contacts the opening (110).

[0035] The base portion (100) has a pair of downward extension portions (140) extending downward from an opening portion (111) at a position spaced apart from each vertical penetration portion (135) in the circumferential direction by a predetermined distance, and a rotational sliding guide portion (180) extending downward from at least a portion of the opening portion (111) in the circumferential section between the vertical penetration portion (135) and the downward extension portion (140).

[0036] The rotary sliding guide part (180) has a sloped section that gradually extends downward from the vertical penetration part (135) to the downward extension part (140). When the rotary sliding guide part (180) rotates in the circumferential direction while the sliding projection part (351) is inserted into the vertical penetration part (135), it comes into contact with the upper surface of the sliding projection part (351).

[0037] The downward extension portion (140) extends downward from an opening edge (111) located at a predetermined distance from one of the pair of vertical penetration portions (135) in the circumferential direction, and extends downward from an opening edge (111) corresponding to a circumferential section between the other vertical penetration portions (135) from the starting point. The length of the circumferential section of the downward extension portion (140) can be adjusted.

[0038] The base portion (100) has a closing portion (170) that extends radially inward from at least a portion of the downwardly extending portion (140). The closing portion (170) has a plate surface (171) that extends laterally so as to be in surface contact with the discharge port edge surface (335). The closing portion (170) may extend radially inward from the entire circumferential portion of the downwardly extending portion (140) as exemplified in the “Applicant’s Invention” mentioned in the background art, or may extend radially inward from a portion of the entire circumferential portion of the downwardly extending portion (140) as in an embodiment according to the present invention. This is related to the position at which the sliding protrusion (351) of the main body (300) protrudes radially outward from the insertion portion (350).

[0039] The above circumferential direction may be clockwise or counterclockwise, but in the drawings according to the present invention, the circumferential direction is expressed as clockwise. The base portion (100) includes a central portion (175) where a pair of closing portions (170) meet each other, and the central portion (175) has a shape that is convex upward like the convex portion (325) of the main body (300). The central portion (175) may not be convex but may be flat. When the main body (300) is inserted into the base portion (100), the central portion (175) and the convex portion (325) are preferably spaced apart from each other.

[0040] The base portion (100) has a cup contact portion (103) extending downward from the lower portion of the expansion portion (130). The cup contact portion (103) comes into contact with the upper portion of the cup (C) disposed at the lower portion. It is preferable that there are at least three cup contact portions (103). Three reinforcing ribs are disposed at the lower portions of each pair of closing portions (170). Each reinforcing rib is connected in the same longitudinal direction as the cup contact portion (103) located at the expansion portion (130), thereby enhancing the durability of the base portion (100).

[0041] Figures 10 and 11 are explanatory drawings showing the open / close state of the discharge port (330) when the main body (300) is rotated relative to the base portion (100). Figure 10 shows the appearance when the sliding protrusion (351) of the main body (300) is inserted into the vertical penetration portion (135) of the base portion (100). At this time, the main body (300) is supported by the closing portion (170), and a pair of discharge ports (330) are in an open position away from the closing portion (170).

[0042] Fig. 11 is a drawing showing the open / close state of the discharge port (330) when the main body (300) is rotated in the circumferential direction at a predetermined angle with respect to the base portion (100) in the state of Fig. 10. Fig. 11 shows a state in which a pair of discharge ports (330) are both closed by the closing portion (170). At this time, the discharge port edge surface (335) and the plate surface (171) of the closing portion (170) come into surface contact with each other, and the discharge port (330) is closed. Fig. 11 may show a state in which the sliding protrusion (351) rotates in the circumferential direction and then comes into contact with the side of the downward extension portion (140) and the rotation is stopped.

[0043] The rotary sliding guide portion (180) has a downwardly inclined portion at least in a portion thereof from the vertical penetration portion (135) toward the downward extension portion (140). Accordingly, the discharge port surface (335) can be brought into contact with the plate surface (171) of the closing portion (170) with a gradually stronger pressure, thereby preventing the liquid beverage from leaking.

[0044] Figures 12 and 13 are perspective views showing two methods by which the base portion (100) can be inserted into the funnel opening (315) of the main body (300). The base portion (100) has a pair of support handles (101A, 101B) extending radially outward from a circular extension portion (130). It is preferable that the pair of support handles (101A, 101B) face each other at an angle of 180 degrees.

[0045] The base part (100) can be supported on the upper part of a cup (C) having a larger diameter than the extension part (130) by having a pair of support handles (101A, 101B). This is because, even if the diameter of the extension part (130) is smaller than the opening of the cup, the pair of support handles (101A, 101B) extending radially outward from both sides can be supported on the upper part of the cup. That is, the base part (100) can be placed on a cup having a diameter ranging from the diameter of the downwardly extending part (140) to the diameter of the pair of handles (101A, 101B).

[0046] The main body (300) has a pair of insertion grooves (303A, 303B) into which a pair of support handles (101A, 101B) of the base part (100) can be inserted. The main body (300) has a main body handle (301) extending radially outward from the lower portion of one of the insertion grooves (303A, 303B).

[0047] Fig. 12 shows a view of the base part (100) inserted into the funnel opening (315) of the main body (300) so that the small support handle (101B) of the base part (100) comes into contact with the main body handle (301), and Fig. 13 shows a view of the base part (100) inserted into the funnel opening (315) so that the large support handle (101A) of the base part (100) comes into contact with the main body handle (301). Since the base part (100) can be inserted into the main body (300) in this way, it is convenient to carry around and the volume can be relatively reduced during storage.

[0048] In this way, a pair of support handles (101A, 101B) can serve as handles that a user can hold with their hands when rotating the base part (100), and can also serve as a support that can be placed on the top of a cup that is larger than the diameter of the extension part (130).

[0049] Figures 14 and 15 are perspective views showing an elastic member (190) spaced apart from a groove (173) of a closing portion (170) and an elastic member (190) inserted into a groove (173) of a closing portion (170) according to another embodiment of the present invention. The base portion (100) according to Figures 14 and 15 has the same configuration as the base portion (100) described in the preceding drawings, except for the groove (173) and the elastic member (190).

[0050] As can be seen in FIGS. 14 and 15, the base portion (100) has a groove portion (173) dug downward to a predetermined depth from the plate surface (171) of the closing portion (170). An elastic member (190) is inserted into the groove portion (173). The elastic member (190) is preferably a silicone rubber that has relatively high elasticity and is stable even at high temperatures and can be used for food.

[0051] The elastic member (190) has an elastic member plate surface (193) that comes into contact with the discharge port edge surface (335) when the discharge port (330) is in the closed position, a side wall (195) that protrudes in the height direction from the arc edge of the elastic member (190) that comes into contact with the downward extension portion (140), a handle projection (191) that is laterally spaced from the elastic member plate surface (193), and a connecting portion (197) that connects the side wall (195) and the handle projection (191).

[0052] As shown in Fig. 15, when the elastic member (190) is inserted into the groove (173), the handle projection (191) is located on the side of the closing member (170). Therefore, the user can relatively easily detach the elastic member (190) from the groove (173) by pulling the exposed handle (191).

[0053] The elastic member (190) can seal the minute gap between the outlet (330) and the closing portion (170) by coming into contact with the outlet edge surface (335) when the outlet (330) is in the closed position. Accordingly, the problem of beverage leakage when the outlet (330) is in the closed position can be solved.
