Description

Technical Field

[0001] The utility model belongs to the technical field of fluid containers and relates to a beverage container. Background Art

[0002] A beverage container is a tool for holding beverages such as beer. For example, a Chinese patent document discloses an anti-backflow bulk wine barrel (application number: 201620747606.6), which includes a barrel body made of food-grade stainless steel, a wine pouring port is provided at the mouth of the barrel body, a 360-degree handle ring seat is provided at the upper end of the barrel body, hollow handles are provided on both sides of the handle ring seat, and the top of the handle ring seat is a rolled process; a base and an air guide tube are provided at the bottom of the barrel body; the air guide tube is located inside the base, one end of the air guide tube is connected to the center of the bottom of the barrel body and communicates with its inner cavity, and the other end passes through the side wall of the base and is connected to a faucet with a quick connector; a check valve and a shut-off valve are provided on the air guide tube; the bottom of the base is a semi-rolled process, and the base can be completely embedded in the handle ring seat; an opening and closing screw head is provided at the upper end of the wine pouring port, and a wine pipe extending to the bottom of the barrel body is provided at the lower end of the wine pouring port, and an exhaust valve is also provided on the top of the barrel body.

[0003] The anti-backflow bulk wine barrel has the following shortcomings during use: when in use, the user needs to open the exhaust valve first to make the atmospheric pressure inside and outside the barrel equal, so that when the user opens the faucet, the wine in the barrel can flow out of the faucet under the action of gravity. However, when the exhaust valve is just opened, due to the carbon dioxide dissolved in the wine and the sudden decrease in the air pressure in the barrel, the carbon dioxide quickly changes from a dissolved state to a gas and is released, forming a large number of bubbles and spraying the wine out of the barrel from the exhaust valve, which not only causes a waste of wine but is also very unhygienic. Summary of the invention

[0004] The purpose of the utility model is to solve the above problems in the existing technology and propose a beverage container. The technical problem to be solved by the utility model is how to ensure drinking hygiene and avoid wasting wine.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A beverage container comprises a barrel body with a wine spear installed, the wine spear having a gas channel and a liquid channel, and the wine spear is also provided with an air guide tube connected to the gas channel and extending to the bottom of the barrel body, characterized in that the barrel body is provided with a long strip-shaped liquid outlet tap connected to the wine spear, the liquid outlet tap has an adjacent air inlet channel and a liquid outlet channel, the air inlet channel and the liquid outlet channel are respectively extended along the length direction of the liquid outlet tap, and the two are respectively connected to the gas channel and the liquid channel, and the inlet of the air inlet channel and the outlet of the liquid outlet channel are adjacently arranged, and the liquid outlet tap is also provided with a switch valve that can control the opening and closing of both the air inlet channel and the liquid outlet channel separately or simultaneously.

[0007] When the beverage container is inverted for use, since the air inlet channel and the liquid outlet channel are both located in the liquid outlet tap, and the inlet of the air inlet channel and the outlet of the liquid outlet channel are adjacent to each other, the wine that initially accidentally enters the air inlet channel can be received simultaneously during the wine receiving process (because the beverage container is to be used inverted, wine will inevitably remain in the air guide tube), thereby avoiding waste and splashing of wine, thereby ensuring drinking hygiene and avoiding waste of wine.

[0008] In addition, users can choose to control the opening and closing of both the air inlet channel and the liquid outlet channel by setting a control knob according to actual usage needs, or they can choose to control the opening and closing of both the air inlet channel and the liquid outlet channel separately by setting multiple control knobs, which is more versatile.

[0009] In the above beverage container, the switch valve includes a telescopic cover movably connected to the liquid outlet faucet, and an air inlet valve core and a liquid outlet valve core respectively arranged at the inlet of the air inlet channel and the outlet of the liquid outlet channel, the air inlet valve core and the liquid outlet valve core are respectively connected to the telescopic cover at the same time, and the air inlet valve core and the liquid outlet valve core can be respectively opened or closed at the same time by controlling the telescopic cover to move along the length direction of the liquid outlet faucet. The user can control the opening and closing of both the air inlet channel and the liquid outlet channel at the same time through a control knob, which is more convenient to operate.

[0010] In the above-mentioned beverage container, the telescopic cover is movably sleeved on the outer side of the liquid outlet faucet, the telescopic cover is threadedly connected with a control knob that can only rotate relative to the control knob, the liquid outlet faucet is provided with a limit block, the telescopic cover is provided with a limit hole, and the limit block is inserted into the limit hole. Through the matching structure of the limit block and the limit hole, the telescopic cover cannot rotate synchronously with the control knob, but can only move linearly, so as to better drive the air inlet valve core and the liquid outlet valve core to open and close the air inlet channel and the liquid outlet channel of the liquid outlet faucet through movement.

[0011] In the above-mentioned beverage container, the control knob is sleeved on the outer side of the telescopic cover, the liquid outlet tap has a limiting protrusion 1 for the telescopic cover to abut against, the limiting protrusion 1 is protruded along the radial direction of the liquid outlet tap, the control knob has a limiting groove, and the limiting protrusion 1 is embedded in the limiting groove. The limiting protrusion 1 can limit the moving distance of the telescopic cover toward the top core part, so that the movement of the telescopic cover is more accurate. At the same time, the limiting protrusion 1 is embedded in the limiting groove, so that the control knob can only rotate but cannot move axially, so that the control knob can better drive the telescopic cover to move back and forth.

[0012] In the beverage container described above, the air inlet valve core and the liquid outlet valve core are provided with annular grooves respectively, and the telescopic cover is provided with two connecting holes, and the hole edges of the two connecting holes are respectively embedded in the two annular grooves. The above structure enables the air inlet valve core and the liquid outlet valve core to move synchronously with the telescopic cover, thereby opening and closing the air inlet channel and the liquid outlet channel of the liquid outlet faucet at the same time.

[0013] In the beverage container described above, the width of the annular groove is greater than the thickness of the edge of the connecting hole. The above structure allows the telescopic cover to have a margin of movement with the air inlet valve core and the liquid outlet valve core, thereby reducing the matching accuracy of the telescopic cover with the air inlet valve core and the liquid outlet valve core, so that the air inlet channel and the liquid outlet channel of the liquid outlet faucet can be opened and closed simultaneously by simply turning the control knob.

[0014] In the beverage container described above, the groove wall height of the annular groove located inside the liquid outlet faucet is greater than the groove wall height outside. The above structure can enhance the structural strength of the groove wall inside the annular groove, so that when the air inlet valve core and the liquid outlet valve core simultaneously close the air inlet channel and the liquid outlet channel of the liquid outlet faucet, the control knob, the telescopic cover and the groove wall inside the annular groove can better abut against each other, thereby preventing the liquid outlet faucet from leaking.

[0015] In the above-mentioned beverage container, the end of the liquid tap connected to the wine spear has a top core portion that is bent upward and can extend into the interior of the wine spear and a plurality of connecting portions located outside the top core portion, and the wine spear has a threaded portion that is spirally connected with the connecting portion. The liquid tap and the wine spear are threadedly connected to facilitate the disassembly and assembly of the two. At the same time, by arranging a plurality of connecting portions on the outside of the top core portion, the liquid tap and the wine spear are rotatably connected, and the top core portion can move into the barrel body and push open the wine spear, so that the air inlet channel and the liquid outlet channel of the liquid tap are respectively connected with the gas channel and the liquid channel of the wine spear, and the operation is more convenient.

[0016] In the above-mentioned beverage container, the telescopic cover is arranged at the end of the liquid outlet faucet away from the wine spear, and the inlet of the air inlet channel and the outlet of the liquid outlet channel are arranged adjacent to the telescopic cover and located at the lower side of the liquid outlet faucet. In this way, the air inlet valve core and the liquid outlet valve core connected to the telescopic cover are located above the inlet of the air inlet channel and the outlet of the liquid outlet channel, which is convenient for the air inlet valve core and the liquid outlet valve core to open and close the inlet of the air inlet channel and the outlet of the liquid outlet channel on the one hand, and also conforms to the habit of receiving wine on the other hand. In addition, the telescopic cover is arranged at the end of the liquid outlet faucet away from the wine spear, which can also prevent the user from bumping against the barrel body during operation.

[0017] In the above beverage container, the inner wall of the barrel body is provided with a plurality of placement grooves for supporting the liquid tap, and when the liquid tap is placed in the plurality of placement grooves, the liquid tap is hidden in the barrel body. In this way, when the barrel body and the liquid tap are not connected, the liquid tap will not be placed randomly, thus avoiding the loss of the liquid tap and not taking up extra storage and packaging space.

[0018] Compared with the prior art, the advantages of the beverage container are: 1. When the beverage container is inverted for use, since the air inlet channel and the liquid outlet channel are both located in the liquid outlet tap, and the inlet of the air inlet channel and the outlet of the liquid outlet channel are adjacent to each other, the wine that accidentally enters the air inlet channel at the beginning can be received at the same time during the wine receiving process (because the beverage container is to be used inverted, it is inevitable that wine will remain in the air guide tube), thereby avoiding the waste and splashing of wine, thereby ensuring drinking hygiene and avoiding the waste of wine.

[0019] 2. The beverage container can control the opening and closing of both the air inlet channel and the liquid outlet channel at the same time through a control knob, which makes the operation more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0030] Embodiment 1

[0031] A beverage container, Figure 1-8 , comprising a barrel body 1 with a wine spear 1a installed, the wine spear 1a having a gas channel 1a2 and a liquid channel 1a3, the wine spear 1a also being provided with an air guide pipe 6 connected to the gas channel 1a2 and extending to the bottom of the barrel body 1, the barrel body 1 being provided with a long strip-shaped liquid outlet tap 2 connected to the wine spear 1a (it should be noted that when the wine spear 1a is not connected to the liquid outlet tap 2, the wine spear 1a is provided with an anti-theft cover 5, so the anti-theft cover 5 should be removed before the wine spear 1a is connected to the liquid outlet tap 2 ), the liquid outlet faucet 2 has an adjacent air inlet channel 2a and a liquid outlet channel 2b, the air inlet channel 2a and the liquid outlet channel 2b are respectively extended along the length direction of the liquid outlet faucet 2, and the two are respectively connected with the gas channel 1a2 and the liquid channel 1a3, and the inlet 2a1 of the air inlet channel 2a and the outlet 2b1 of the liquid outlet channel 2b are adjacently arranged, and the liquid outlet faucet 2 is also provided with a switch valve 3 which can control the opening and closing of the air inlet channel 2a and the liquid outlet channel 2b separately or simultaneously.

[0032] Specifically, refer to Figure 1-8The switch valve 3 includes a telescopic cover 3a movably connected to the liquid outlet faucet 2, and an air intake valve core 3b and a liquid outlet valve core 3c respectively arranged at the inlet 2a1 of the air intake channel 2a and the outlet 2b1 of the liquid outlet channel 2b, the air intake valve core 3b and the liquid outlet valve core 3c are respectively connected to the telescopic cover 3a, and the air intake valve core 3b and the liquid outlet valve core 3c can be respectively opened or closed simultaneously on the telescopic cover 3a by controlling the telescopic cover 3a to move along the length direction of the liquid outlet faucet 2; the end of the liquid outlet faucet 2 connected to the wine spear 1a has a top core part 2f bent upward and capable of extending into the interior of the wine spear 1a, and a plurality of connecting parts 2g located outside the top core part 2f, and the wine spear 1a has a threaded part 1a1 spirally connected to the connecting part 2g.

[0033] In this embodiment, the telescopic cover 3a is preferably arranged at the end of the liquid outlet faucet 2 away from the wine spear 1a, and the inlet 2a1 of the air inlet channel 2a and the outlet 2b1 of the liquid outlet channel 2b are both arranged adjacent to the telescopic cover 3a and located at the lower side of the liquid outlet faucet 2.

[0034] More specifically, refer to Figure 1-8 The telescopic cover 3a is movably sleeved on the outer side of the liquid outlet faucet 2, and a control knob 3d that can only rotate relative to the telescopic cover 3a is threadedly connected thereto. The liquid outlet faucet 2 is provided with a limit block 2c, and a limit hole 3a1 is provided on the telescopic cover 3a, and the limit block 2c extends into the limit hole 3a1; the control knob 3d is sleeved on the outer side of the telescopic cover 3a, and the liquid outlet faucet 2 is provided with a limit protrusion 2d for the telescopic cover 3a to abut against, and the limit protrusion 2d is protruded along the radial direction of the liquid outlet faucet 2, and the control knob 3d is provided with a limit groove 3d1, and the limit protrusion 2d is embedded in the limit groove 3d1.

[0035] More specifically, refer to Figure 1-8 The air inlet valve core 3b and the liquid outlet valve core 3c are respectively provided with an annular groove 4, and the telescopic cover 3a is provided with two connecting holes 3a2, and the hole edges of the two connecting holes 3a2 are respectively embedded in the two annular grooves 4.

[0036] In this embodiment, the width of the annular groove 4 is preferably greater than the thickness of the edge of the connecting hole 3a2; the height of the groove wall of the annular groove 4 located on the inner side of the liquid outlet faucet 2 is preferably greater than the height of the groove wall on the outer side.

[0037] Further, refer to Figure 1 and Figure 8 The inner wall of the barrel body 1 is provided with a plurality of placement grooves 1b for supporting the liquid outlet faucet 2, and when the liquid outlet faucet 2 is placed in the plurality of placement grooves 1b, the liquid outlet faucet 2 is hidden in the barrel body 1.

[0038] Here's how the beverage container works:

[0039] When in use, the user needs to first remove the anti-theft cover 5 on the barrel body 1 (if a dust cover is provided in the anti-theft cover 5, it should also be removed together), then the user removes the liquid tap 2 from the barrel body 1, and then the several connecting parts 2g of the liquid tap 2 are threadedly connected with the wine spear 1a on the barrel body 1. When the liquid tap and the wine spear are connected in place, the top core part 2f of the liquid tap 2 pushes the wine spear 1a, and the air inlet channel 2a and the liquid outlet channel 2b of the liquid tap 2 are respectively connected with the air inlet channel and the liquid outlet channel of the wine spear 1a, and then the user turns the control knob 3d , the control knob 3d drives the telescopic cover 3a to move in the direction away from the top core portion 2f. Specifically, since the limiting block 2c extends into the limiting hole 3a1, the telescopic cover 3a cannot rotate synchronously with the control knob 3d, but can only move in a straight line. In addition, the limiting protrusion 2d is embedded in the limiting groove 3d1, so that the control knob 3d can only rotate but cannot move axially. When the control knob 3d is rotated, the thread on the control knob 3d will pull the telescopic cover 3a away from the top through the thread on the telescopic cover 3a. The core 2f moves in the direction of the telescopic cover 3a (similar to the working principle of the screw nut), and the air inlet valve core 3b and the liquid outlet valve core 3c move synchronously with the telescopic cover 3a, so that the air inlet channel 2a and the liquid outlet channel 2b of the liquid outlet faucet 2 are opened at the same time, so that the atmospheric pressure inside and outside the barrel body 1 is equal, and the wine in the barrel body 1 flows out from the liquid outlet channel 2b of the liquid outlet faucet 2 under the action of gravity and flows into the wine glass. When the wine is received, the user rotates the control knob 3d in the opposite direction. At this time, the telescopic cover 3a and the limiting protrusion 2d, the control knob 3d and the limiting protrusion 2d are 2e respectively have a moving spacing, the control knob 3d drives the telescopic cover 3a to move toward the direction close to the top core portion 2f, at this time, the thread on the control knob 3d will push the telescopic cover 3a to move toward the direction close to the top core portion 2f through the thread on the telescopic cover 3a, and the air inlet valve core 3b and the liquid outlet valve core 3c move synchronously with the telescopic cover 3a, so that the air inlet channel 2a and the liquid outlet channel 2b of the liquid outlet faucet 2 are closed at the same time, at this time, the telescopic cover 3a is abutted against the limiting protrusion 2d, and the wine no longer flows out of the liquid outlet channel 2b of the liquid outlet faucet 2.

[0040] It should be noted that when the beverage container is used inverted, since the air inlet channel 2a and the liquid outlet channel 2b are both located in the liquid outlet faucet 2, and the inlet 2a1 of the air inlet channel 2a and the outlet 2b1 of the liquid outlet channel 2b are adjacent to each other, the wine that initially mistakenly enters the air inlet channel 2a can be received at the same time during the wine receiving process (because the beverage container is to be used inverted, it is inevitable that wine will remain in the air duct), thereby avoiding waste and splashing of wine, thereby ensuring drinking hygiene and avoiding waste of wine.

[0041] Embodiment 2

[0042] The structure and principle of this embodiment are basically the same as those of the first embodiment, except that: there are two telescopic covers 3a and two control knobs 3d (not shown in the figure), the two telescopic covers 3a are movably mounted on the outside of the liquid outlet faucet 2, the air inlet valve core 3b and the liquid outlet valve core 3c are respectively connected to the two telescopic covers 3a, and the two control knobs 3d are respectively threadedly connected to the outside of the telescopic covers 3a, so that the opening and closing of the air inlet channel and the liquid outlet channel are respectively controlled by setting a plurality of control knobs.

[0043] Embodiment 3

[0044] The structure and principle of this embodiment are basically the same as those of the first embodiment, and the difference is that: the liquid outlet faucet 2 also has a second limiting protrusion 2e arranged adjacent to the first limiting protrusion 2d, and the second limiting protrusion 2e is also convexly arranged along the radial direction of the liquid outlet faucet 2, and the control knob 3d is rotated to abut against the second limiting protrusion 2e. The control knob 3d is rotated to abut against the second limiting protrusion 2e, which can prevent the control knob 3d from being skewed during the rotation process, so that the telescopic cover 3a moves more accurately under the drive of the control knob 3d, and on the other hand, makes the liquid outlet faucet 2 look more tightly fitted as a whole.

[0045] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
