Description

Technical Field

[0001] The present invention relates to a food and beverage storage device for storing food and beverages that are easily changed when exposed to air (such as wine or vinegar). Background Art

[0002] Typically, after wine is put into a wine bottle, the mouth of the wine bottle is sealed with a stopper made of a material such as a cork. When the cork is opened to enjoy the wine, the wine comes into contact with oxygen and oxidizes within a few hours to produce a sour taste, rather than the original taste of the wine.

[0003] Therefore, in order to experience the original taste of wine, it is best to drink all the wine stored in the wine bottle as soon as possible after opening the wine bottle. However, it is not practical to drink all the wine at once. Therefore, a storage method is needed to prevent the remaining wine from oxidizing.

[0004] As a prior art example, Korean Patent No. 10-0960617 discloses an oxygen-absorbing component provided on a stopper to more quickly and effectively remove oxygen from the wine bottle when resealing it, thereby reducing oxygen contact with the wine while allowing further air to flow into the bottle.

[0005] However, placing wine bottles horizontally can lead to the loss of the oxygen-absorbing component's preservation function. Consequently, the bottles cannot be carried around or stored horizontally in a wine cabinet. In particular, wines, which are sensitive to temperature and ultraviolet rays, cannot be preserved unless they are stored in a cellar.

[0006] Furthermore, in the prior art, the oxygen absorbing components are disposable products with a short shelf life, and need to be constantly replaced with new ones, thus resulting in a high cost. Summary of the Invention

[0007] Technical issues

[0008] The problem to be solved by the present invention is to provide a food and beverage storage container that can minimize contact with air without purchasing additional components.

[0009] Another problem to be solved by the present invention is to provide a food and beverage storage container that can prevent air from further flowing into the interior of the container.

[0010] Another problem to be solved by the present invention is to provide a food and beverage storage container which can prevent air from flowing into the interior of the container even when placed horizontally and can be stored horizontally in a cellar.

[0011] Technical Solutions

[0012] In order to solve the above technical problems, according to a preferred aspect of the present invention, a food and beverage storage device can be provided, which includes: a container for containing food and beverages; and a piston part, which is tightly attached to the inner surface of the container and can be moved in the up and down directions, the piston part includes: a neck, the interior of which is empty and can be moved in the up and down directions, the neck including: a discharge part, which protrudes upward at the upper end of the neck, and the discharge part is formed with a first screw part and a first discharge groove on the outer peripheral surface, and is used to discharge food and beverages or air in the container; a first guide part, which is inclined upward in a direction opposite to the first discharge groove at a position spaced apart from the discharge part; and a first accumulation part, formed between the discharge part and the first guide part, for accumulating the discharged food and beverages.

[0013] In which, the neck may include: a second guide portion, which is formed by tilting upward on a portion of the outer circumference of the upper end of the neck; a flow-proof flange, which protrudes upward from the second guide portion; a discharge outlet, which is connected to the second guide portion and is formed by tilting downward on a portion of the outer circumference of the upper end of the neck toward the front end; and a second accumulation portion, which is formed between the discharge outlet and the first guide portion and is used to accumulate the discharged food and beverage.

[0014] The lower end of the discharge portion is formed with a second discharge groove connected to the first discharge groove, and the piston portion may include: a discharge pipe accommodated inside the neck and inserted and coupled to the second discharge groove to serve as a channel for the movement of food and beverages in the container.

[0015] The piston portion may include an inner cover accommodated in the neck portion, wherein a groove at one end of the inner cover is combined with the discharge pipe.

[0016] In which, the piston part includes: a blocking cover, which is inserted and coupled to the other end of the inner cover, and a fourth discharge groove is formed at one end of the blocking cover. When the blocking cover is inserted and coupled to the inner cover, the center of the fourth discharge groove and the center of the groove of the inner cover can be staggered with each other.

[0017] Effects of the Invention

[0018] The present invention has the effect of extending the storage time of food and beverages (for example, wine) that are easily changed when exposed to air.

[0019] Furthermore, the present invention has the effect of completely sealing the wine while it is being stored, so that the wine stored inside is not easy to flow, and thus the wine can be not only carried but also stored in a cellar or the like.

[0020] Furthermore, the present invention has the effect of minimizing contact with air regardless of the amount of food and beverage stored therein, thereby ensuring a longer storage period.

[0021] Furthermore, the present invention has the effect of minimizing contact with air without purchasing additional parts.

[0036] Figure 1 FIG. 1 is a front view of a food and beverage storage device according to an embodiment of the present invention.

[0037] Reference Figure 1 The food and beverage storage device 10 includes a container 100 , a piston portion 200 and a stopper 300 .

[0038] The upper end of the container 100 is open, and food and beverages can be placed inside.

[0039] The piston part 200 can move in the vertical direction while being in close contact with the inner surface of the container 100 , and thus, the air inside the container 100 can be effectively removed according to the amount of remaining food or beverage.

[0040] The stopper 300 is mounted to or detached from the piston part 200 at an upper side of the piston part 200 to prevent air from entering the interior of the container 100 .

[0041] Figure 2 2 is a structural diagram of a piston portion according to an embodiment of the present invention.

[0042] Figure 3 FIG. 1 is a diagram for explaining a neck portion according to an embodiment of the present invention.

[0043] Figure 4 1 is a structural diagram of a plug according to an embodiment of the present invention.

[0044] Figure 5 1 is a diagram showing a conceptual diagram of a plug according to an embodiment of the present invention when coupled to a piston portion.

[0045] Reference Figures 2 to 5 The piston portion 200 includes a neck portion 210 , a discharge pipe 220 , a guide portion 230 , a lower end cover 240 , a sealing portion 250 , an inner cover 260 and a blocking cover 270 .

[0046] The interior of the neck 210 is hollow and moves vertically in response to user manipulation, allowing it to be moved within and outside the container 100. Furthermore, the neck 210 comprises an upper neck 210-1 and a lower neck 210-2. Partially threaded outer surfaces of the upper and lower necks 210-1 and 210-2 allow for interlocking and disassembly. The threaded underside of the upper neck 210-1 is inserted into the interior of the lower neck 210-2, thereby preventing air or food and beverages that have passed through the third discharge groove 241 of the lower end cap 240 and the perforated space within the lower neck 210-2 from being discharged to locations other than the blocking cap 270 and the inner cap 260.

[0047] The neck portion 210 includes a discharge portion 211 , a first flow guide portion 212 , a second flow guide portion 213 , a flow prevention flange 214 , a discharge port 215 , a first accumulation portion 216 , and a second accumulation portion 217 .

[0048] The discharge portion 211 is formed at the upper end of the neck 210 , preferably, protrudes upward from the upper end of the upper neck 210 - 1 . The discharge portion 211 is used to discharge food and beverages or air inside the container 100 that moves through the discharge pipe 220 .

[0049] Furthermore, a first screw portion 211 - 1 and a first discharge groove 211 - 2 are formed on the outer peripheral surface of the discharge portion 211 , and a second discharge groove 211 - 3 is formed at the lower end.

[0050] The first screw portion 211-1 is coupled to or detached from the second screw portion 330 of the stopper 300. As described above, as the first screw portion 211-1 is coupled to or detached from the second screw portion 330, the drain portion 211 is coupled to or detached from the watertight portion 320 of the stopper 300, so that the drain portion 211 is exposed or blocked through the watertight portion 320.

[0051] The first discharge groove 211 - 2 is formed at a position corresponding to the direction of the discharge port 215 on a portion of the outer circumferential surface of the discharge portion 211 to discharge food, beverage or air moving through the discharge pipe 220 and the second discharge groove 211 - 3 .

[0052] The diameter of the first discharge groove 211-2 is 4 mm to 5 mm. When the diameter of the first discharge groove 211-2 is less than 4 mm, the pressure in the container 100 is less than the pressure outside the container 100, and there is a problem that the food and beverage cannot be discharged through the first discharge groove 211-2. Specifically, because the amount of food and beverage discharged through the first discharge groove 211-2 is too small, there is a problem that it takes a lot of time for the food and beverage accumulated in the first accumulation part 216 and the second accumulation part 217 to reach the height above the discharge part 215 and be discharged through the discharge part 215. When the diameter of the first discharge groove 211-2 is greater than 5 mm, due to the high discharge pressure, the food and beverage discharged through the first discharge groove 211-2 will overflow the discharge port 215, that is, there is a problem that it is discharged directly to the outside of the food and beverage storage device 10.

[0053] The second discharge groove 211 - 3 is formed at the lower end of the discharge portion 211 in such a manner as to communicate with the first discharge groove 211 - 2 , such that one end of the discharge pipe 220 is inserted and coupled to the second discharge groove 211 - 3 .

[0054] The first guide portion 212 is at the upper end of the neck 210, preferably, at a position separated from the discharge portion 211 at the upper end of the upper neck 210-1 and inclined upward in the opposite direction of the first discharge groove 211-2, so as to guide the food and beverage overflowing from at least one of the second accumulation portion 217 and the first accumulation portion 216 after being discharged through the first discharge groove 211-2 to move to at least one of the second accumulation portion 217 and the first accumulation portion 216.

[0055] The second guide portion 213 is at the upper end of the neck 210, preferably, at a portion of the outer circumference of the upper end of the upper neck 210-1 that is inclined upward, and is used to guide food and beverages overflowing from at least one of the first accumulation portion 216, the second accumulation portion 217 and the first guide portion 212 to move to at least one of the first accumulation portion 216, the second accumulation portion 217 and the first guide portion 212.

[0056] The anti-flow flange 214 protrudes upward from the second flow guide portion 213 to prevent food and beverages from overflowing to the outside over the second flow guide portion 213. The height of the anti-flow flange 214 may be greater than 2 mm.

[0057] The outlet 215 is connected to the second guide portion 213 and is formed at the upper end of the neck 210, preferably at the upper end of the upper neck 210-1, with the outer peripheral surface thereof tilted downward toward the front end. The outlet 215 is used to discharge food and beverages to the outside. The angle of the outlet 215 is approximately 25 degrees, and the length can be at least 5 mm.

[0058] Specifically, the food and beverage discharged through the first discharge chute 211-2 is discharged into the second accumulating portion 217 and accumulated in the second accumulating portion 217 and the first accumulating portion 216. When the height of the discharged food and beverage reaches or exceeds the height of the discharge port 215, the food and beverage is discharged to the outside through the discharge port 215. At this time, when the amount of food and beverage discharged through the first discharge chute 211-2 is greater than the amount discharged through the discharge port 215, causing the food and beverage accumulated in the second accumulating portion 217 and the first accumulating portion 216 to move to at least one of the first guide portion 212 and the second guide portion 213, the food and beverage that has moved to at least one of the first guide portion 212 and the second guide portion 213 is guided by at least one of the inclined first guide portion 212 and the second guide portion 213 and moves to at least one of the second accumulating portion 217 and the first accumulating portion 216. In addition, the food and beverages moved to the second guide portion 213 are blocked by the anti-flow flange 214 and cannot overflow to the outside, and are then guided by the second guide portion 213 and moved to at least one of the second accumulating portion 217 and the first guide portion 212 .

[0059] As described above, after food and beverages are discharged through first discharge chute 211-2, they accumulate in second accumulating portion 217 and first accumulating portion 216. When the discharged food and beverages reach a level higher than discharge outlet 215, they are discharged to the outside through discharge outlet 215. Therefore, the user can consume food and beverages using a cup, etc., without having to tilt or turn the food and beverage storage device 10. This prevents air from entering the food and beverage storage device 10 when tilting or turning it. Furthermore, due to first flow guide 212, second flow guide 213, and flow prevention flange 214, even if a large amount of food and beverages are discharged through first discharge chute 211-2, the food and beverages do not overflow. Instead, they are guided to second accumulating portion 217 and first accumulating portion 216 and discharged to the outside through discharge outlet 215.

[0060] The first accumulating portion 216 is formed between the discharge portion 211 and the first flow guide portion 212 , and the second accumulating portion 217 is formed between the discharge portion 211 and the discharge port 215 .

[0061] The first and second accumulating portions 216 and 217 serve as accumulation areas for food and beverages discharged through the first discharge chute 211-2. In a food and beverage storage device 10 according to a preferred embodiment of the present invention, food and beverages discharged through the first discharge chute 211-2 are not directly discharged to the outside of the food and beverage storage device 10. Instead, they are first discharged and accumulated in the first and second accumulating portions 216 and 217. When the level of the discharged food and beverages reaches or exceeds the level of the discharge port 215, the food and beverages are discharged to the outside of the food and beverage storage device 10 through the discharge port 215. The watertight portion 320 of the stopper 300 can be inserted into the first accumulating portion 216 when coupled to the discharge portion 211.

[0062] Discharge tube 220 is housed within neck portion 210, preferably within upper neck portion 210-1. One end of discharge tube 220 is coupled to second discharge groove 211-3, and the other end is coupled to inner cover 260. This allows food and beverages or air in the container to pass through third discharge groove 241 and into first discharge groove 211-2. When a portion of one end of discharge tube 220 is inserted into second discharge groove 211-3, it can connect to first discharge groove 211-2. In other words, discharge tube 220 is insertable into discharge portion 211.

[0063] When the shape of the discharge pipe 220 is circular, as shown in FIG. Figure 2 As shown, the shape of the second discharge groove 211-3 can be rectangular, but is not limited thereto. The shape of the second discharge groove 211-3 can be circular. In addition, when the shape of the discharge pipe 220 is circular, the diameter of the discharge pipe 220 is 4mm to 5mm, and the length is 5mm to 40mm.

[0064] An experiment was conducted to fill the container 100 of the food and beverage storage device 10 with 650 ml of water and then invert the device 10 to examine the effect of air entering the container 100 through the discharge tube 220 under different discharge tube 220 diameters and lengths. The experimental results showed that when the discharge tube 220 diameter was 6 mm or greater, air flowed into the container 100 through the discharge tube 220, discharging food and beverages from the container 100, regardless of the length of the discharge tube 220. Furthermore, when the discharge tube 220 diameter was 5 mm, air flowed into the container 100 through the discharge tube 220 when the length of the discharge tube 220 was less than 5 mm, but did not flow into the container 100 through the discharge tube 220 when the length of the discharge tube 220 was 5 mm or greater. In addition, when the diameter of the discharge pipe 220 is less than 4 mm or the length of the discharge pipe 220 is more than 40 mm, the pressure in the container 100 is lower than the pressure outside the container 100, and the problem of food and beverage being unable to be discharged through the first discharge groove 211-2 occurs. Specifically, since the amount of food and beverage discharged through the first discharge groove 211-2 is too small, the food and beverage accumulated in the first accumulation section 216 and the second accumulation section 217 reaches above the height of the discharge section 215 and it takes a lot of time to be discharged through the discharge section 215.

[0065] Therefore, it can be confirmed that the diameter of the discharge pipe 220 needs to be 4mm to 5mm and the length needs to be 5mm to 40mm in order to discharge food and beverage through the first discharge groove 211-2 and prevent external air from entering the container 100 through the discharge pipe 220.

[0066] In addition, in a preferred embodiment of the present invention, when the cross-section of the discharge pipe 220 is rectangular, as shown in FIG. Figure 2 As shown, it is recommended that the second discharge groove 211-3 be rectangular in shape, and the diagonal length of the discharge tube 220 be 4mm to 5mm. This is because air bubbles tend to assume a spherical shape to reduce surface area. However, if the diagonal length of the discharge tube 220 is less than 4mm, air inside the container 100 becomes trapped in the discharge tube 220 and cannot move through it, preventing the air from being discharged to the outside through the first discharge groove 211-2. Conversely, if the diagonal length of the discharge tube 220 is greater than 5mm, if air enters through the first discharge groove 211-2, it will pass through the discharge tube 220 into the inner cover 260 and into the interior of the container 100.

[0067] Furthermore, in a preferred embodiment of the present invention, when the cross-section of the discharge pipe 220 is triangular, the second discharge groove 211-3 is also triangular, and the longest side of the discharge pipe 220 cross-section is 4 to 5 mm long. This is because air tends to assume a spherical shape to reduce surface area. However, if the longest side of the discharge pipe 220 cross-section is less than 4 mm, air inside the container 100 becomes trapped in the discharge pipe 220 and cannot move through it, resulting in the air being unable to be discharged to the outside through the first discharge groove 211-2. Conversely, when the longest side of the discharge pipe 220 cross-section is 5 mm or longer, if air enters through the first discharge groove 211-2, it will pass through the discharge pipe 220 into the inner cover 260 and into the interior of the container 100.

[0068] The guide portion 230 is fixed to the upper end of the container 100 and has a hole formed in the middle thereof for the neck 210 to pass through, thereby playing a guiding role when the neck 210 slides in the up and down directions.

[0069] The lower end cap 240 is coupled to the lower end of the neck portion 210, preferably to the lower end of the lower neck portion 210-2, and has a third discharge groove 241 formed in the center thereof. This allows food and beverages in the container 100 or air inside the container 100 to pass through the third discharge groove 241 and move through the neck portion 210, preferably through the empty space inside the lower neck portion 210-2. The lower end cap 240 may be integrally formed at the lower end of the neck portion 210, preferably at the lower end of the lower neck portion 210-2.

[0070] The sealing portion 250 is coupled to the outer peripheral surface of the lower end cap 240 and maintains a close contact with the inner surface of the container 100 to prevent food and beverage from flowing out of the container 100. To this end, the sealing portion 250 can be made of a material such as silicon or rubber to maintain a close contact with the inner surface of the container 100.

[0071] The inner cap 260 is inserted into and accommodated in the neck portion 210, preferably, in the upper neck portion 210-1. The interior of the inner cap 260 is hollow, and one end is provided with a groove for coupling with the discharge pipe 220, while the other end is provided for the insertion and coupling of the blocking cap 270. Furthermore, even if the blocking cap 270 is inserted and coupled to the inner cap 260, since there is still empty space inside the inner cap 260, the food and beverage in the container 100 or the air inside the container 100 that moves through the empty space inside the neck portion 210, preferably, the lower neck portion 210-2, is discharged through the fourth discharge groove 271 of the blocking cap 270 and stored inside, and then moves through the discharge pipe 220 connected to one end of the blocking cap 270.

[0072] The blocking cover 270 is made of rubber or silicon and is inserted into the other end of the inner cover 260 and is located between the upper neck 210-1 and the lower neck 210-2 to prevent air or beverage from leaking through the gap. One end of the blocking cover 270 inserted into the other end of the inner cover 260 is formed with a fourth discharge groove 271. The diameter of the fourth discharge groove 271 is greater than 2 mm, and the fourth discharge groove 271 is formed upwardly inclined from the two ends of the other end of the blocking cover 270. The lower portion of the other end of the blocking cover 270 is formed with a groove, and the interior is empty. At this time, when the blocking cover 270 is inserted and coupled to the inner cover 260, the fourth discharge groove 271 of the blocking cover 270 is formed at a position that is staggered (i.e., does not correspond to) the center of the groove at one end of the inner cover 260 for the discharge pipe 220 to be coupled. That is, the center of the fourth discharge groove 271 and the center of the groove of the inner cover 260 are staggered with each other. As described above, the fourth discharge groove 271 is formed at a position offset from (i.e., not corresponding to) the center of the groove of the discharge tube 220 to prevent air flowing in through the discharge tube 220 from flowing into the container 100 and being trapped in the empty space of the inner lid 260. Specifically, air flowing into the empty space of the inner lid 260 through the discharge tube 220 descends toward the container 100. However, because the center of the fourth discharge groove 271 is offset from the center of the groove of the inner lid 260, the air does not flow into the fourth discharge groove 271 but instead moves to the upwardly inclined portion of the fourth discharge groove 271 and becomes trapped in the empty space of the inner lid 260. Consequently, even if the food and beverage storage device 10 is tilted or turned over to discharge food and beverages, air flowing into the empty space of the inner lid 260 through the discharge tube 220 does not move toward the container 100.

[0073] Furthermore, fourth discharge groove 271 is formed at a position offset from (i.e., not corresponding to) the center of the groove of discharge pipe 220 so that, when food and beverage are discharged through fourth discharge groove 271, air trapped in the empty space of inner cover 260 is discharged through first discharge groove 211-2. Specifically, when the center of fourth discharge groove 271 coincides with the center of the groove of inner cover 260, pressure is applied to the food and beverage, which passes through discharge pipe 220 coupled to the groove of inner cover 260 and is discharged directly through first discharge groove 211-2. Air trapped in the empty space of inner cover 260 outside fourth discharge groove 271 is not discharged and remains trapped in the empty space of inner cover 260. On the contrary, as in a preferred embodiment of the present invention, if the center of the fourth discharge groove 271 and the center of the groove of the inner cover 260 are offset from each other, the food and beverage discharged through the fourth discharge groove 271 is not discharged directly into the discharge pipe 220 combined with the groove of the inner cover 260, but is discharged into the empty space of the inner cover 260, and then passes through the discharge pipe 220 combined with the groove of the inner cover 260 together with the air trapped in the empty space of the inner cover 260, and is discharged through the first discharge groove 211-2. Figure 3 Although not shown in the figure, a handle is provided at the other end of the blocking cover 270 to facilitate the user to separate the blocking cover 270.

[0074] The stopper 300 is coupled to or detached from the upper end of the neck 210 to prevent air from entering the interior of the container 100 , and includes a housing 310 , a watertight portion 320 and a second screw portion 330 .

[0075] The upper end of the shell 310 is closed and the lower end is open to accommodate and cover the discharge portion 211, the first guide portion 212, the second guide portion 213, the flow prevention flange 214, the first accumulation portion 216 and the second accumulation portion 217 (except the discharge port 215) formed at the upper end of the neck 210.

[0076] The watertight portion 320 protrudes from a portion of the bottom surface of the housing 310. When the piston portion 200 and the stopper 300 are engaged, the watertight portion 320 vertically and downwardly penetrates the discharge portion 211 from the upper side thereof and is inserted into the first accumulating portion 216, thereby sealing the discharge portion 211 and preventing external air from entering the container 100 through the discharge portion 211 and preventing food and beverages in the container 100 from being discharged to the outside through the discharge opening 211. Although not shown in the drawings, an O-ring made of rubber or silicone is interposed between the watertight portion 320 and the discharge portion 211. This, together with the watertight portion 320, prevents external air from entering the container 100 through the discharge portion 211 and prevents food and beverages in the container 100 from being discharged to the outside through the discharge opening 211. When the watertight portion 320 is inserted and engaged with the discharge portion 211, a residual space of at least 2 mm is provided between the watertight portion 320 and the discharge portion 211.

[0077] The second screw portion 330 is formed on the inner circumference of the watertight portion 320 to be coupled with the first screw portion 211 - 1 and detached from the first screw portion 211 - 1 , thereby coupling the discharge portion 211 with the watertight portion 320 and detaching the discharge portion 211 from the watertight portion 320 .

[0078] Figure 6 and Figure 7 This is a diagram showing a concept of storage of food and beverages after exhausting the air according to an embodiment of the present invention.

[0079] After removing the upper neck portion 210-1, the discharge tube 220, the inner cover 260, the blocking cover 270 and the plug 300 from the empty food and beverage storage device 10 ( Figure 6 (a)), pour the food and beverages in the other containers 400 into the empty container 100 through the lower neck 210-2 ( Figure 6 (b)).

[0080] like Figure 7 As shown in (a), after the upper neck 210-1, the discharge pipe 220, the inner cover 260, and the blocking cover 270 are again connected to the lower neck 210-2, the plug 300 is removed from the piston part 200. Then, as shown in FIG. Figure 7 As shown in (b), the piston portion 200 is pressed downward to expel air. Specifically, when the user grasps the neck portion 210 and moves it downward, the lower end cap 240 and the sealing portion 250 move downward. Due to the pressure in the container 100, the air inside the container 100 moves through the third exhaust groove 241 and the exhaust pipe 220 to the first exhaust groove 211-2, and then is exhausted to the outside. After all the air is exhausted, the plug 300 is attached to the piston portion 200 to prevent external air from entering the container 100 through the exhaust portion 211.

[0081] Figure 8This figure shows a usage concept diagram of discharging food and beverages stored in a food and beverage storage device according to one embodiment of the present invention.

[0082] like Figure 8 As shown in (a), the plug 300 is removed from the piston portion 200 so that the discharge portion 211 is exposed to the outside. Figure 8 As shown in (b), the piston portion 200 is pressed downward to discharge the food and beverage to the outside of the discharge portion 211. Specifically, when the user grasps the neck portion 210 and moves it downward, as the lower end cap 240 and the sealing portion 250 move downward, the food and beverage stored in the container 100 moves to the first discharge groove 211-2 through the third discharge groove 241 and the discharge pipe 220 with the help of the pressure in the container 100, and is then discharged to the outside through the first discharge groove 211-2. The food and beverage discharged through the first discharge groove 211-2 is then discharged to the second accumulation portion 217 and accumulated in the second accumulation portion 217 and the first accumulation portion 216. When the height of the discharged food and beverage reaches or exceeds the height of the discharge port 215, it is discharged to the outside through the discharge port 215. When discharging food and beverages contained in the container 100, the container 100 can be tilted after removing the upper neck 210-1, the discharge tube 220, the inner cover 260, the blocking cover 270 and the stopper 300, and the food and beverages can be discharged through the lower neck 210-2.

[0083] Figure 9 This is a diagram showing a usage concept of storing food and beverages inside according to another embodiment of the present invention.

[0084] After removing the piston 200 and the stopper 300 from the container 100 of the empty food and beverage storage device 10 ( Figure 9 (a)), pour the food and beverage in another container 400 into the empty container 100 ( Figure 9 (b)).

[0085] The above describes an embodiment of the food and beverage storage device according to the present invention. However, this is only described as at least one embodiment and does not limit the technical concept, structure, and function of the present invention. Therefore, the scope of the technical concept of the present invention is not limited / restricted by the drawings or the description with reference to the drawings.
