Description

Liquid discharge structure of beverage container Technical Field

[0001] The invention belongs to the technical field of beverage containers and relates to a liquid outlet structure of a beverage container. Background Art

[0002] The upper end of the existing beverage container is provided with a dispensing valve, and the beverage can be dispensed through the dispensing valve by pushing the valve stem of the dispensing valve downward toward the inner space of the container. In order to operate the dispensing valve, a liquid outlet channel is provided between the dispensing valve and the outlet. After the dispensing valve is closed to complete the liquid dispensing, the liquid remaining in the liquid outlet channel will slowly drip out of the outlet under the action of air pressure. As a result, when the beverage container dispenses the beverage, liquid still flows out of the liquid outlet channel after the dispensing valve is closed. Since the residual liquid flows out slowly, the user needs to wait for a long time before removing the cup receiving the beverage, which causes inconvenience to the user.

[0003] To address the above-mentioned issues, Chinese patent document [Authorization Announcement No.: CN1671613B] discloses a beverage container comprising a dispensing valve and a dispensing channel connected to the dispensing valve. An opening is provided on the underside of the dispensing channel, near the air end adjacent to the dispensing valve. When the dispensing valve is in the closed position, the opening connects the dispensing channel to the surrounding environment. A flexible element, such as an elastic pad made of plastic or rubber, is placed on the housing below the opening. When the dispensing valve is opened and the dispensing channel moves downward, the opening is pressed against the flexible element, thereby closing the opening and causing the flexible element to slightly elastically deform. When the dispensing valve is closed and the dispensing channel moves upward again, the opening opens, reconnecting the dispensing channel to the surrounding environment. Thus, due to the provision of the opening, after the dispensing valve is closed, the dispensing channel connects to the surrounding environment through the opening, balancing the air pressure, thereby enabling the beverage in the dispensing channel to be quickly emptied without requiring the user to wait for an extended period of time.

[0004] When the dispensing valve is opened, the above-described structure requires the dispensing channel to move to the opening so that it abuts the flexible element, achieving a seal through the flexible element to ensure normal flow of the beverage. Due to the small size of the beverage container, the flexible element is not only difficult to install, but also simply placed on the housing below the opening, without forming a stable fixed connection. This can easily lead to the flexible element remaining in contact with the opening as the dispensing channel moves upward, preventing the residual liquor from being quickly drained. This leads to a failure to reliably prevent liquor from remaining after the dispenser is closed. However, if the dispensing channel is moved downward by a shorter distance, it is more likely that the dispensing channel will not move downward enough, resulting in a lack of reliable contact between the opening and the flexible element. In this case, although the opening and the flexible element can separate when the dispensing channel moves upward, allowing the residual liquid to drain quickly, the sealing effect will deteriorate when the dispensing channel moves downward, affecting the normal flow of the beverage. In addition, it can be clearly seen from the drawings in the above patent document specification that the flexible element is placed on a protrusion, which may easily cause the flexible element to be unstable on the protrusion after deformation, affecting the sealing effect and easily causing problems that affect the normal flow of beverages from the dispenser. Summary of the Invention

[0005] The purpose of the present invention is to address the above-mentioned problems existing in the prior art and propose a liquid outlet structure for a beverage container. The technical problem to be solved by the present invention is: how to solve the problem of the existing beverage container preventing liquid from remaining in the distribution channel while affecting the normal outflow of the liquid.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A liquid outlet structure for a beverage container, the beverage container includes a main body with an inner cavity, the liquid outlet structure includes a distribution valve arranged on the main body, the distribution valve has a liquid outlet pipe, and is characterized in that a vent hole is opened on the upper wall of the liquid outlet pipe, a sealing member is provided on the liquid outlet pipe, the sealing member and the valve wall of the distribution valve are combined to form an upward-opening air passage, the lower edge of the sealing member is fixedly connected to the wall of the liquid outlet pipe around the orifice of the vent hole, a liquid outlet handle is hinged on the main body, which can control the connection between the liquid outlet pipe and the inner cavity, and the liquid outlet handle has a limiting piece that can press the upper end of the seal against the valve wall of the distribution valve to close the air passage.

[0008] When the user needs to drain the liquid from the beverage container, he only needs to turn the liquid discharge handle. Since the liquid discharge handle is hinged on the beverage container, the liquid discharge handle can swing to connect the liquid discharge pipe of the dispensing valve with the inner cavity, thereby realizing liquid discharge. The liquid can flow out of the liquid discharge pipe to the outside of the beverage container. At this time, the limiting piece on the liquid discharge handle presses the upper end of the seal against the valve wall of the dispensing valve, so that the air passage is disconnected from the outside, thereby ensuring that the liquid discharge pipe does not leak in the air passage, so that the liquid can flow out of the liquid discharge pipe stably. When the liquid has been collected, the user resets the liquid discharge handle, and the limiting piece on the liquid discharge handle is reset synchronously with the liquid discharge handle. The liquid discharge pipe is connected to the external environment through the vent hole and the air passage, so that the air pressure in the liquid discharge pipe returns to normal, and the liquid in the liquid discharge pipe can be quickly discharged, thereby avoiding liquid remaining in the liquid discharge pipe after the liquid discharge handle is reset, improving the discharge efficiency of the residual liquid of the liquid discharge structure, and thus improving the convenience of the user.

[0009] By securely connecting the lower edge of the seal to the wall of the liquid outlet pipe, the sidewall of the seal and the valve seat together form a gas passage, making the overall seal arrangement more stable. When the stopper of the liquid passage handle squeezes the seal, the seal can be stably positioned on the liquid outlet pipe, improving the stability of the seal arrangement and ensuring normal liquid discharge when the dispensing valve is opened. Therefore, the liquid discharge structure of this beverage container not only allows for rapid emptying of residual liquid when the dispensing valve is closed, but also ensures normal liquid discharge when the dispensing valve is opened.

[0010] In the liquid outlet structure of the beverage container, the dispensing valve includes a valve seat, the outer side wall of the valve seat protrudes outward to form the liquid outlet pipe, and the sealing member is fixedly connected to the outer side wall of the valve seat on the side where the liquid outlet pipe is provided.

[0011] By fixedly connecting the seal to the outer side wall of the distribution valve seat, the connection between the seal, the valve seat and the liquid outlet pipe is made more stable, which not only ensures the sealing performance of the seal and the liquid outlet pipe, but also ensures the sealing performance between the seal and the valve seat, so that the lumen of the liquid outlet pipe can only be connected to the outside world through the vent hole and the air passage, thereby improving the stability of the liquid outlet structure and ensuring normal liquid discharge.

[0012] In the liquid outlet structure of the above-mentioned beverage container, the sealing member is a U-shaped sealing plate, which includes a force-bearing part that can be squeezed and deformed by the limiting plate and a connecting part connected to both sides of the force-bearing part and connected to the valve wall of the distribution valve. The force-bearing part and the connecting part are both flat.

[0013] Through the arrangement of the force-bearing part and the connecting part, the entire air passage is square and the upper end is connected to the outside air. When the limiting plate squeezes the force-bearing part, the arrangement of the connecting parts on both sides makes the deformation of the force-bearing part easier. The force-bearing part is flat, which can increase the contact area with the limiting plate, making the extrusion faster and more uniform, thereby ensuring the sealing of the liquid outlet pipe during the liquid discharge process.

[0014] In the above-mentioned liquid outlet structure of the beverage container, the end of the limiting piece capable of squeezing the force-bearing portion is the squeezing end, and the width of the squeezing end is greater than the width of the force-bearing portion.

[0015] The size setting of the extrusion end and the force-bearing part enables the extrusion end to stably squeeze the force-bearing part onto the outer wall of the valve seat, further improving the sealing performance of the liquid outlet pipe during the liquid discharge process.

[0016] In the above-mentioned liquid outlet structure of the beverage container, the end surface of the extruding end facing the force-bearing portion is an arcuate surface, and the side surface of the extruding end facing away from the force-bearing portion is a straight surface.

[0017] The setting of the curved surface can avoid the large impact force of the extrusion end on the force-bearing part when the liquid discharge handle swings too fast, and can also increase the contact area, so that the sealing effect is better. The setting of the straight surface can ensure the sealing performance between the end face of the extrusion end and the force-bearing part after abutment, thereby improving the normal liquid discharge efficiency of the liquid discharge pipe.

[0018] In the above-mentioned liquid outlet structure of the beverage container, the sealing member and the valve wall of the dispensing valve are integrally injection-molded.

[0019] The arrangement of this structure makes the arrangement of the sealing member more convenient and stable, and prevents the sealing member from loosening from the distribution valve after long-term use.

[0020] In the liquid outlet structure of the above-mentioned beverage container, two limit plates arranged symmetrically along the axial direction are provided on the valve core in the valve seat, and the liquid flow handle has limit arms arranged one-to-one corresponding to the limit plates. The rotation of the liquid flow handle can drive the limit arms to lift the limit plates upward, and the limit plate is located between the two limit arms.

[0021] The position setting of the limit plate enables the limit plate to squeeze the force-bearing part to rest against the outer wall of the distribution valve when the limit arm lifts the limit plate upward. On the one hand, the limit plate can close the air passage, and on the other hand, it can enhance the structural strength of the liquid handling handle, making the liquid handling handle more stable when discharging liquid.

[0022] In the liquid outlet structure of the beverage container, the liquid outlet end of the liquid outlet pipe is sleeved with a liquid outlet tap that can slide along the liquid outlet pipe. The liquid outlet end of the liquid outlet pipe is sleeved with a sealing ring that abuts against the inner side wall of the liquid outlet tap.

[0023] When it is necessary to dispense wine, the outlet end of the liquid discharging faucet can be pulled out of the main body. Since the liquid discharging end of the liquid discharging tube is sleeved with a sealing ring, the sealing between the liquid discharging faucet and the liquid discharging tube is not affected after the liquid discharging faucet is pulled out. After the liquid is discharged, the outlet end of the liquid discharging faucet can be retracted onto the main body, which is convenient for the transportation of the beverage container and also prevents impurities from entering from the outlet end of the liquid discharging faucet when not in use, thereby improving the stability of the liquid discharging structure.

[0024] In the liquid outlet structure of the beverage container, the body is provided with a clearance hole for the liquid outlet tap to extend out, and a projection is formed on the outer wall of the liquid outlet tap to form a shift rod, which can abut against the inner wall of the body.

[0025] The setting of the shift lever avoids directly pulling the entire liquid faucet out of the body, and improves the stability of the liquid faucet by limiting the pulling stroke of the liquid faucet.

[0026] In the liquid outlet structure of the above-mentioned beverage container, the outer wall of the middle part of the sealing ring protrudes radially outward to form an extrusion portion, the cross-section of the extrusion portion is triangular, and the extrusion portion has a guide surface, which is inclined outward in the direction from the liquid outlet end of the liquid outlet pipe to the liquid inlet end of the liquid outlet pipe.

[0027] The setting of the sealing ring ensures that when the liquid faucet is pulled outward, the extrusion part can form a certain resistance and also produce a large deformation to ensure the sealing between the liquid faucet and the liquid outlet pipe. When the liquid faucet retracts inward, it can play a guiding role, thereby making the use of the liquid faucet more convenient and stable.

[0028] In the above-mentioned liquid outlet structure of the beverage container, the shift lever is arranged at the lower side of the liquid outlet tap, and the shift lever is arranged obliquely downward from the liquid inlet end to the liquid outlet end of the liquid outlet pipe.

[0029] The position setting of the shift lever can give way to the limit plate, thereby improving the stability of the liquid outlet structure.

[0030] Compared to the prior art, the liquid outlet structure of this beverage container has the following advantages: after receiving the liquid, the user resets the liquid handling handle, and the stopper on the liquid handling handle is simultaneously reset. The liquid outlet pipe is connected to the external environment through the vent hole and the air passage, allowing the air pressure in the liquid outlet pipe to return to normal and the liquid in the liquid outlet pipe to be quickly discharged. This prevents liquid from remaining in the liquid outlet pipe after the liquid handling handle is reset, improves the liquid outlet efficiency of the liquid outlet structure, and thus enhances user convenience. By firmly connecting the lower edge of the seal to the wall of the liquid outlet pipe and the side wall of the seal and the valve seat to form an air passage, the overall seal arrangement is more stable. When the stopper of the liquid handling handle squeezes the seal, the seal can be stably fixed on the liquid outlet pipe, improving the stability of the seal arrangement and ensuring normal liquid outlet when the dispensing valve is opened. Therefore, the liquid outlet structure of this beverage container not only allows for rapid emptying of residual liquid when the dispensing valve is closed, but also ensures normal liquid outlet when the dispensing valve is opened.

DETAILED DESCRIPTION

[0042] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0043] Example 1

[0044] As shown in Figures 1 and 3, the liquid outlet structure of the beverage container includes a main body 1 having an inner cavity 11. The main body 1 includes a barrel and a cover. The cover is fixed to the upper end of the barrel, and the inner cavity 11 is set in the barrel. The liquid outlet structure includes a distribution valve 2 set on the top of the barrel of the main body 1, and the distribution valve 2 has a liquid outlet pipe 21. The distribution valve 2 includes a valve seat 22, and the valve seat 22 has a valve hole connected to the liquid outlet pipe 21. The valve hole has a valve core 23 that can slide up and down. The upper end of the valve core 23 extends out of the valve seat 22, and the lower end of the valve core 23 can abut against the sealing ring of the valve seat 22 to block the valve hole. The valve seat 22 is also provided with an air inlet passage 24, through which high-pressure gas can enter the inner cavity 11 of the main body 1.

[0045] As shown in Figures 3 and 4, a vent hole 21a is provided on the upper wall of the liquid outlet pipe 21. A seal 3 is provided on the liquid outlet pipe 21. The seal 3 and the valve wall of the distribution valve 2 form an upward-opening air passage 4. The lower edge of the seal 3 is fixedly connected to the wall of the liquid outlet pipe 21 around the opening of the vent hole 21a. A liquid handling handle 5 is hinged on the cover of the main body 1 to control the connection between the liquid outlet pipe 21 and the inner cavity 11. As shown in Figures 6, 7 and 8, one end of the liquid handling handle 5 is a hinged end hinged to the cover of the main body 1, and the other end is a driving end. The valve core 23 in the valve seat 22 is provided with two axially symmetrically arranged limit plates 23a. The limit plates 23a are located at the upper end of the valve core 23 and extend out of the valve seat 22. The liquid handling handle 5 has arcuate limit arms 52, each corresponding to the limit plates 23a. The handle 5 also has a flat limit plate 51, located between the two limit arms 52, with a gap between each side of the limit plate 51 and the corresponding limit arm 52. Both the limit plate 51 and the limit arm 52 are located at the hinged end of the liquid handling handle 5, facing downward. As shown in Figures 6 and 10 , rotation of the liquid handling handle 5 drives the limit arms 52 to lift the limit plates 23a upward, causing the limit plate 51 to press the upper end of the seal 3 against the wall of the dispensing valve 2, thereby sealing the air passage 4.

[0046] As shown in Figures 3, 4 and 6, the outer wall of the valve seat 22 protrudes outward to form the above-mentioned liquid outlet pipe 21, the seal 3 is fixedly connected to the outer wall of the distribution valve 2 on the side where the liquid outlet pipe 21 is set, and the seal 3 and the valve seat 22 of the distribution valve 2 are integrally injection molded.

[0047] As shown in Figures 4 and 6, the sealing member 3 is a U-shaped sealing piece. The sealing piece includes a force-bearing portion 31 that can be squeezed and deformed by the limiting piece 51, and a connecting portion 32 connected to both sides of the force-bearing portion 31 and connected to the valve wall of the distribution valve 2. Both the force-bearing portion 31 and the connecting portion 32 are flat. The end of the limiting piece 51 that can squeeze the force-bearing portion 31 is the squeezing end 51a. As shown in Figure 7, the width b2 of the squeezing end 51a is greater than the width b1 of the force-bearing portion 31. The end surface of the squeezing end 51a facing the force-bearing portion 31 is an arcuate surface 51a1, and the side surface of the squeezing end 51a facing away from the force-bearing portion 31 is a straight surface 51a2.

[0048] As shown in Figures 3, 9, and 10, the liquid outlet end 21b of the liquid outlet pipe 21 is sleeved with a liquid outlet tap 6 that can slide along the liquid outlet pipe 21 and can extend and retract relative to the main body 1. A sealing ring 7 is sleeved with the liquid outlet end 21b of the liquid outlet pipe 21, and the sealing ring 7 abuts against the inner sidewall of the liquid outlet tap 6. As shown in Figures 1 and 2, the cover of the main body 1 is provided with a clearance hole 12 for the liquid outlet tap 6 to extend. The outer sidewall of the liquid outlet tap 6 protrudes to form a shift rod 61, which abuts against the inner sidewall of the cover of the main body 1. As shown in Figures 5 and 6, the outer sidewall of the sealing ring 7 protrudes radially outward in the middle to form an extrusion portion 71. The extrusion portion 71 has a triangular cross-section and includes a guide surface 71a. The guide surface 71a is arranged to be inclined outward from the liquid outlet end 21b of the liquid outlet pipe 21 to the liquid inlet end 21c of the liquid outlet pipe 21. The shift rod 61 is arranged on the lower side of the liquid outlet faucet 6, and the shift rod 61 is arranged obliquely downward in the direction from the liquid inlet end 21c of the liquid outlet pipe 21 to the liquid outlet end 21b of the liquid outlet pipe 21.

[0049] As shown in Figures 4 and 9, the inlet end of the liquid tap 6 has a shielding plate 62, which can be located above the air passage 4. The shielding plate 62 prevents large debris or dust from entering the air passage 4 and blocking the vent 21a when the beverage container is not in use, thereby preventing the air passage 4 and the vent 21a from being inconvenient to use after being stored for too long.

[0050] Working principle: The barrel of the main body 1 is filled with beverages, and the lower end of the valve seat 22 is connected to a vertical pipe opposite to the valve hole, and the lower end of the vertical pipe is located at the bottom of the barrel. As shown in Figure 10, when the liquid in the beverage container needs to flow out normally, first pull out the liquid tap 6 and place the liquid receiving cup under the outlet of the liquid tap 6; then bend the driving end of the liquid handling handle 5, and after the liquid handling handle 5 swings, the limit arm 52 lifts the limit plate 23a upward, and the valve core 23 moves upward to open the valve hole, so that the liquid outlet pipe 21 of the distribution valve 2 is connected with the inner cavity 11. At the same time, the limit plate 51 on the liquid handling handle 5 presses the upper end of the sealing member 3 against the valve wall of the distribution valve 2, so that the air passage 4 is disconnected from the outside, thereby ensuring that the liquid outlet pipe 21 does not leak at the air passage 4; then high-pressure gas is introduced into the barrel body through the air inlet passage 24. Under the action of the high-pressure gas pressure, the liquid in the barrel body enters the distribution valve 2 along the vertical pipe, and flows out from the outlet of the liquid tap 6 after passing through the valve hole of the distribution valve 2, the liquid outlet pipe 21 and the liquid tap 6; thereby achieving stable liquid discharge, and the liquid can flow out of the beverage container normally from the liquid outlet pipe 21. After the closure is closed, the closure 21 is opened and the valve element 21 is in a closed position, and the closure 22 is in a closed position, and the closure 22 is in a closed position, and the closure 22 is in a closed position, and the closure 22 is in a closed position, and the closure 22 is in a closed position, and the closure 22 is in a closed position, and the closure 22 is in a closed position, and the closure 22 is in a closed position, and the closure 22 is in a closed position, and the closure 22 is in a closed position, and the closure 22 is in a closed position, and the closure 22 is in a closed position, and the closure 22 is in a closed position, and the closure 22 is in a closed position, and the closure 22 is in a closed position, and the closure 22 is in a closed position, and the closure 22 is in a closed position, and the closure 22 is in a closed position, and the closure 22 is in a closed position, and the closure 22 is in a closed position, and the closure 22 is in a closed position, and the closure 22 is in a closed position, and the closure 22 is in a closed position, and the closure 22 is in a closed position, and the closure 22 is in a closed position, When normal liquid discharge is completed, the residual liquid in the liquid discharge pipe 21 and the liquid discharge tap 6 can be quickly emptied, thereby preventing liquid from remaining in the liquid discharge pipe 21 after the liquid release handle 5 is reset. This improves the residual liquid discharge efficiency of the liquid discharge structure and thus improves user convenience. Therefore, the liquid discharge structure of this beverage container not only allows for rapid emptying of residual liquid when the dispensing valve 2 is closed, but also ensures normal liquid discharge when the dispensing valve 2 is opened.

[0051] Example 2

[0052] The structure of the sealing member 3 differs slightly from that of the first embodiment. The sealing member 3 is a C-shaped sealing disc, the open side of which is fixedly connected to the outer wall of the valve seat 22, and the lower end of which is fixedly connected to the liquid outlet pipe 21. The outer wall of the valve seat 22 corresponding to the sealing member 3 is convexly arc-shaped, and the extrusion end 51a of the limiting disc 51 is correspondingly concavely arc-shaped. When the liquid flow handle 5 is rotated, the extrusion end 51a of the limiting disc 51 is capable of pressing the upper end of the sealing member 3 against the outer wall of the valve seat 22.

[0053] The other structures are the same as those in Example 1. The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments, without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
