Description

[Technical field]

[0001] The present invention relates to a food and beverage storage device for storing food and beverages such as wine and vinegar that are susceptible to deterioration when exposed to air. [Background technology]

[0002] Generally, wine is packaged in a wine bottle, with the opening of the bottle sealed with a stopper made of a material such as cork. However, when the cork is opened to enjoy such wine, the wine comes into contact with oxygen and oxidizes within a few hours, resulting in a sour taste rather than the original flavor of the wine.

[0003] Therefore, in order to enjoy the original taste of wine, it is best to drink all the wine stored inside the wine bottle as soon as possible after opening it. However, since it is practically difficult to drink all the wine in one go, a method is needed to store the remaining wine in a way that prevents it from oxidizing.

[0004] An example of such a prior art is Patent Document 1. In the prior art, when resealing a wine bottle, an oxygen absorbing member is installed in the stopper to more quickly and effectively remove oxygen from inside the wine bottle, thereby reducing contact between oxygen and wine while allowing additional air to flow into the wine bottle.

[0005] However, there is a problem that the preservation function of the oxygen absorbing material is lost when the wine bottle is turned over, which causes further problems that the bottle cannot be carried around and that the wine bottle cannot be stored upside down in a cellar. In particular, if the wine cannot be stored in a cellar, it is impossible to preserve wine, which is sensitive to temperature and ultraviolet rays.

[0006] Furthermore, in the conventional technology, the oxygen absorbing member is disposable and can only be stored for a short period of time, so that the oxygen absorbing member must be replaced with a new one continuously, resulting in high costs. [Prior art documents] [Patent documents]

[0027] FIG. 1 is a front view of a food and beverage storage device according to one embodiment of the present invention.

[0028] Referring to FIG. 1, a food and beverage storage device 10 includes a container 100 , a piston portion 200 , and a stopper 300 .

[0029] The container 100 has an open top and can contain food and drink.

[0030] Since the piston portion 200 can move up and down while being in close contact with the inner surface of the container 100, the air inside the container 100 can be effectively removed depending on the amount of food or drink remaining.

[0031] The plug 300 is attached to and detached from the piston part 200 from the upper side of the piston part 200 to prevent air from entering the inside of the container 100.

[0032] FIG. 2 is a configuration diagram of a piston portion according to an embodiment of the present invention. FIG. 3 is a diagram illustrating a neck portion according to an embodiment of the present invention. FIG. 4 is a diagram of a plug according to one embodiment of the present invention. FIG. 5 is a conceptual diagram showing a state in which a plug is combined with a piston according to an embodiment of the present invention.

[0033] 2 to 5, the piston portion 200 includes a neck portion 210, a discharge pipe 220, a guide portion 230, a lower end cap 240, a sealing portion 250, an inner cap 260, and a protective cap 270.

[0034] The neck 210 is open inside and moves up and down by the user's operation to move inside and outside the container 100. The neck 210 is composed of an upper neck 210-1 and a lower neck 210-2, and the upper neck 210-1 and the lower neck 210-2 have threads on part of their outer peripheries so that they can be attached and detached from each other. The lower side of the threads of the upper neck 210-1 is inserted into the lower neck 210-2, and the third discharge groove 241 of the bottom cap 240 prevents air and food that move through an empty space perforated inside the lower neck 210-2 from being discharged anywhere other than the blocking cap 270 and the inner cap 260.

[0035] The neck portion 210 includes a discharge portion 211 , a first flow guide portion 212 , a second flow guide portion 213 , a flow prevention step 214 , a discharge port 215 , a first accumulation portion 216 , and a second accumulation portion 217 .

[0036] The exhaust portion 211 is formed to protrude upward from the upper end of the neck portion 210, preferably from the upper end of the upper neck portion 210-1, and exhausts food or beverage that has moved through the exhaust pipe 220 or air inside the container 100.

[0037] Further, a first threaded portion 211-1 and a first discharge groove 211-2 are formed on the outer circumferential surface of the discharge portion 211, and a second discharge groove 211-3 is formed at the lower end.

[0038] The first threaded portion 211-1 is coupled to and detached from the second threaded portion 330 of the plug 300. As the first threaded portion 211-1 is coupled to and detached from the second threaded portion 330 in this manner, the outlet portion 211 is detached from the watertight portion 320 of the plug 300, and the outlet portion 211 is exposed or blocked by the watertight portion 320.

[0039] The first discharge groove 211-1 is formed in a portion of the outer circumferential surface of the discharge part 211 corresponding to the direction of the discharge port 215, and discharges food, drink, or air that has moved through the discharge pipe 220 and the second discharge port 211-3.

[0040] The diameter of the first discharge groove 211-1 is 4 mm to 5 mm or less, because if the diameter of the first discharge groove 211-2 is 4 mm or less, the pressure inside the container 100 is lower than the pressure outside the container 100, and food and beverages are not discharged through the first discharge groove 211-2. In particular, the amount of food and beverages discharged through the first discharge groove 211-2 is too small, and it takes a long time for the food and beverages accumulated in the first and second accumulation parts 216 and 217 to reach the height of the discharge part 215 or higher and be discharged through the discharge part 215. If the diameter of the first discharge groove 211-2 is 5 mm or more, the discharge pressure is too strong, and the food and beverages discharged through the first discharge groove 211-2 exceed the discharge port 215, that is, are immediately discharged to the outside of the food and beverage storage device 10.

[0041] The second discharge groove 211-3 is formed at the lower end of the discharge part 211 to communicate with the first discharge groove 211-2, and one end of the discharge pipe 220 is inserted and coupled thereto.

[0042] The first flow guide portion 212 is formed at the upper end of the neck 210, preferably at the upper end of the upper neck portion 210-1, spaced apart from the discharge portion 211, and inclined upward in the opposite direction to the first discharge groove 211-2, and guides the food and beverage that has overflowed 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 one of the second accumulation portion 217 and the first accumulation portion 216.

[0043] The second flow guide portion 213 is formed with an upward incline on the upper end of the neck portion 210, preferably on a portion of the outer peripheral surface of the upper end of the upper neck portion 210-1, and guides food and beverage overflowing from at least one of the first and second pools 216, 217 and the first flow guide portion 212 to move to at least one of the first and second pools 216, 217 and the first flow guide portion 212.

[0044] The flow prevention step 214 protrudes upward from the second flow guide portion 213 to prevent food and drink from overflowing beyond the second flow guide portion 213. Here, the height of the flow prevention step 214 may be 2 mm or more.

[0045] The outlet 215 is connected to the second flow guide 213 and is formed on the upper end of the neck 210, preferably on a part of the outer circumferential surface of the upper end of the upper neck 210-1, inclined downward toward the front end so that food and drink can be discharged to the outside. Here, the inclination angle of the outlet 215 is about 25 degrees, and the length is 5 mm or more.

[0046] In detail, food and beverage discharged through first discharge groove 211-2 is discharged into second accumulation portion 217, and when the height of food and beverage discharged after accumulating in second accumulation portion 217 and first accumulation portion 216 becomes equal to or exceeds the height of discharge outlet 215, it is discharged to the outside through discharge outlet 215. At this time, if the amount of food and beverage discharged through first discharge groove 211-2 is greater than the amount discharged through discharge outlet 215 and the food and beverage accumulated in second accumulation portion 217 and first accumulation portion 216 exceeds at least one of first flow guide portion 212 and second flow guide portion 213, the food and beverage that exceeds at least one of first flow guide portion 212 and second flow guide portion 213 is guided and moved to at least one of second accumulation portion 217 and first accumulation portion 216 by at least one of inclined first flow guide portion 212 and second flow guide portion 213. In addition, food and beverage that has exceeded the second flow guide section 213 is blocked by the flow prevention step 214 and cannot overflow to the outside, and is guided and moves through the second flow guide section 213 to at least one of the second accumulation section 217 and the first flow guide section 212.

[0047] In this way, when the food and beverages are discharged through the first discharge groove 211-2 and accumulated in the second accumulation portion 217 and the first accumulation portion 216, and the height of the discharged food and beverages reaches or exceeds the discharge outlet 215, the food and beverages are discharged to the outside through the discharge outlet 215, so that the user can drink the food and beverages using a cup or the like without tilting or turning the food and beverage storage device 10, and the problem of air flowing into the food and beverage storage device 10 when tilting or turning the food and beverage storage device 10 can be prevented. In addition, even if the amount of food and beverages discharged through the first discharge groove 211-2 is large, the food and beverages are guided to the second accumulation portion 217 and the first accumulation portion 216 without overflowing to the outside due to the first flow guide portion 212, the second flow guide portion 213, and the flow prevention step 214, and are discharged to the outside through the discharge outlet 215.

[0048] The first accumulation portion 216 is formed between the discharge portion 211 and the first flow guide portion 212 , and the second accumulation portion 217 is formed between the discharge portion 211 and the discharge port 215 .

[0049] The first and second collecting parts 216, 217 are where the food and beverage discharged through the first discharge groove 211-2 accumulates, and in the food and beverage storage device 10 of a preferred embodiment of the present invention, the food and beverage discharged through the first discharge groove 211-2 is not immediately discharged to the outside of the food and beverage storage device 10, but is first discharged and collected in the first and second collecting parts 216, 217, and when the height of the discharged food and beverage reaches or exceeds the height of the discharge opening 215, the food and beverage is discharged to the outside of the food and beverage storage device 10 through the discharge opening 215. Here, the watertight part 320 of the plug 300 can be inserted into the first collecting part 216 when it is coupled with the discharge part 211.

[0050] The discharge pipe 220 is accommodated inside the neck 210, preferably inside the upper neck 210-1, and has one end connected to the second discharge groove 211-3 and the other end connected to the inner cap 260, thereby forming a passage through which food or drink contained in the container or air inside the container moves to the first discharge groove 211-2 via the third discharge groove 241. Here, a portion of one end of the discharge pipe 220 may be connected to the first discharge groove 211-2 when inserted into the second discharge groove 211-3. That is, the discharge pipe 220 may be inserted into the discharge portion 211.

[0051] 2, if the shape of the discharge pipe 220 is circular, the shape of the second discharge groove 211-3 may be rectangular, but is not limited thereto, and the shape of the second discharge groove 211-3 may be circular. Also, if the shape of the discharge pipe 220 is circular, the diameter of the discharge pipe 220 is 4 mm to 5 mm or less, and the length is 5 mm to 40 mm or less.

[0052] An experiment was conducted on whether air would enter the container 100 through the discharge pipe 220 depending on the diameter and length of the discharge pipe 220 when the container 100 of the food and beverage storage device 10 was filled with 650 ml of water and then turned upside down. As a result of the experiment, a problem occurred in which air would enter the container 100 through the discharge pipe 220 regardless of the length of the discharge pipe 220 if the diameter of the discharge pipe 220 was 6 mm or more, and food and beverages in the container 100 would be discharged. In addition, when the diameter of the discharge pipe 220 was 5 mm or less, air would enter the container 100 through the discharge pipe 220 if the length of the discharge pipe 220 was less than 5 mm, and no air would enter the container 100 through the discharge pipe 220 if the length of the discharge pipe 220 was 5 mm or more. In addition, if the diameter of discharge pipe 220 is 4 mm or less or the length of discharge pipe 220 is 40 mm or more, the pressure inside container 100 is lower than the pressure outside container 100, and food and beverage are not discharged through first discharge groove 211-2. More specifically, the amount of food and beverage discharged through first discharge groove 211-2 is too small, and the food and beverage accumulated in first and second accumulation portions 216, 217 reaches or exceeds the height of discharge portion 215, and it takes a long time for the food and beverage to be discharged through discharge portion 215.

[0053] It was confirmed that unless the diameter of the exhaust pipe 220 is 4 mm to 5 mm or less and the length is 5 mm to 40 mm or less, food and drink cannot be discharged through the first exhaust groove 211-2 and outside air cannot be prevented from entering the inside of the container 100 through the exhaust pipe 220.

[0054] In addition, in a preferred embodiment of the present invention, when the cross section of the exhaust pipe 220 is rectangular, it is suggested that the second exhaust groove 211-3 is rectangular and the diagonal length of the cross section of the exhaust pipe 220 is 4 mm to 5 mm or less as shown in Fig. 2. This is because, in the case of air, it becomes spherical to reduce the surface area, but if the diagonal length of the cross section of the exhaust pipe 220 is less than 4 mm, there is a problem that the air inside the container 100 is stuck on the exhaust pipe 220 and cannot move through the exhaust pipe 220, and the air cannot escape to the outside through the first exhaust groove 211-2. On the other hand, if the diagonal length of the cross section of the exhaust pipe 220 is 5 mm or more, when air enters through the first exhaust groove 211-2, the air enters the inner cap 260 through the exhaust pipe 220 and enters the inside of the container 100.

[0055] In addition, in a preferred embodiment of the present invention, if the cross section of the exhaust pipe 220 is triangular, the second exhaust groove 211-3 is also triangular and the length of the longest side of the cross section of the exhaust pipe 220 is 4 mm to 5 mm or less. This is because, in the case of air, it becomes spherical to reduce the surface area, but if the length of the longest side of the cross section of the exhaust pipe 220 is less than 4 mm, there is a problem that the air inside the container 100 is hung on the exhaust pipe 220 and cannot move through the exhaust pipe 220, and the air cannot escape to the outside through the first exhaust groove 211-2. On the other hand, if the length of the longest side of the cross section of the exhaust pipe 220 is 5 mm or more, when air enters through the first exhaust groove 211-2, the air enters the inner cap 260 through the exhaust pipe 220 and enters the inside of the container 100.

[0056] The guide part 230 is fixed to the upper end of the container 100 and has a hole in the center through which the neck part 210 passes, and serves to guide the neck part 210 when it slides up and down.

[0057] The bottom cap 240 is coupled to the bottom end of the neck 210, preferably the lower neck 210-2, and has a third discharge groove 241 formed in the center thereof, through which food or drink in the container 100 or air inside the container 100 moves through an empty space inside the neck 210, preferably the lower neck 210-2. Here, the bottom cap 240 may be integrally formed with the bottom end of the neck 210, preferably the lower neck 210-2.

[0058] The sealing part 250 is coupled to the outer circumferential surface of the lower end cap 240 and is maintained in close contact with the inner surface of the container 100 to prevent food and beverages from leaking out of the container 100. To this end, the sealing part 250 is made of a material such as silicone or rubber and is capable of maintaining close contact with the inner surface of the container 100.

[0059] The inner cap 260 is inserted and accommodated in the neck 210, preferably the upper neck 210-1, and the inner cap 260 has an open interior, one end of which is grooved to be connected to the discharge pipe 220, and the other end of which is inserted and connected to the blocking cap 270. Even when the blocking cap 270 is inserted and connected to the inner cap 260, there is an empty space inside, so that food or drink in the container 100 or air inside the container 100 that moves through the empty space inside the neck 210, preferably the lower neck 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.

[0060] The blocking cap 270 is made of rubber or silicon material, and is inserted and coupled to the other end of the inner cap 260, and is interposed between the upper neck part 210-1 and the lower neck part 210-2 to prevent air or beverage from leaking through the gap. The one end inserted into the other end of the inner cap 260 has a fourth discharge groove 271 with a diameter of 2 mm or more formed at both ends of the other end of the blocking cap 270, inclined upward, and a groove is formed at the lower part of the other end, and the inside is empty. In this case, the fourth discharge groove 271 of the blocking cap 270 is formed at a position that does not correspond to the center of the groove to which the discharge pipe 220 of one end of the inner cap 260 is coupled when the blocking cap 270 is inserted and coupled to the inner cap 260. In other words, the center of the fourth discharge groove 271 and the center of the groove of the inner cap 260 are offset from each other. The fourth discharge groove 271 is formed at a position that does not correspond to the center of the groove of the discharge pipe 220 in order to confine the air flowing in through the discharge pipe 220 in the empty space of the inner cap 260 without flowing into the container 100. In detail, the air flowing in the empty space of the inner cap 260 through the discharge pipe 220 descends toward the container 100, but since the center of the fourth discharge groove 271 and the center of the groove of the inner cap 260 are offset from each other, the air does not flow into the fourth discharge groove 271, but moves to the upwardly inclined part of the fourth discharge groove 217 and is confined in the empty space of the inner cap 260. As a result, even if the food storage device 10 is tilted or turned upside down to discharge food, the air flowing in the empty space of the inner cap 260 through the discharge pipe 220 cannot move toward the container 100.

[0061] In addition, the fourth discharge groove 271 is formed at a position offset from the center of the groove of the discharge pipe 220 in order to discharge air trapped in the empty space of the inner cap 260 through the first discharge groove 211-2 when food or drink is discharged through the fourth discharge groove 271. In particular, if the center of the fourth discharge groove 271 and the center of the groove of the inner cap 260 are aligned, only food or drink is immediately discharged through the first discharge groove 211-2 via the discharge pipe 220 connected to the groove of the inner cap 260 by pressure, and air trapped in the empty space of the inner cap 260 other than the fourth discharge groove 271 is not discharged and remains trapped in the empty space of the inner cap 260. On the other hand, if the center of the fourth discharge groove 271 and the center of the groove of the inner cap 260 are offset from each other as in a preferred embodiment of the present invention, the food or drink discharged into the fourth discharge groove 271 is not immediately discharged into the discharge pipe 220 connected to the groove of the inner cap 260, but is discharged through the first discharge groove 211-2 via the discharge pipe 220 connected to the groove of the inner cap 260 together with the air trapped in the empty space of the inner cap 260 after it is connected to the groove of the inner cap 260. Here, although not shown in FIG 3, a handle may be provided at the other end of the blocking cap 270 to allow the user to easily separate the blocking cap 270.

[0062] The plug 330 is attached to and detached from the upper end of the neck 210 from above the upper end of the neck 210 to prevent air from entering the inside of the container 100, and includes a housing 310, a watertight portion 330, and a second screw portion 330.

[0063] The housing 310 has a closed upper end and an open lower end, and accommodates and closes the discharge section 211, the first flow guide section 212, the second flow guide section 213, the flow prevention step 214, the first accumulation section 216, and the second accumulation section 217 formed at the upper end of the neck section 210 excluding the discharge outlet 215.

[0064] Watertight portion 320 is formed to protrude from a portion of the bottom surface of housing 310, and when piston portion 200 and stopper 300 are combined, it enters vertically downward from above discharge portion 211 toward discharge portion 211 and is inserted into first reservoir portion 216, blocking discharge portion 211 and preventing outside air from entering container 100 through discharge portion 211 and preventing food and beverages in container 100 from being discharged to the outside through discharge outlet 211. Here, although not shown, an O-ring made of a rubber or silicone material is further connected between the watertight portion 320 and the discharge portion 211 to prevent, together with the watertight portion 320, outside air from entering the container 100 through the discharge portion 211 and to prevent, together with the watertight portion 320, the food and beverage in the container 100 from being discharged to the outside through the discharge port 211. However, when the watertight portion 320 is inserted into and connected to the discharge portion 211, there may be a clearance space of 2 mm or more between the watertight portion 320 and the discharge portion 211.
