Description

Technical Field

[0001] The utility model belongs to the technical field of beverage drinking equipment and relates to a beverage barrel. Background Art

[0002] Common beverages include water, juice, tea, coffee, and wine. When demand for beverages is high, efficient, hygienic, and safe beverage distribution can be achieved through the use of beverage dispensing devices. This quickly and accurately dispenses large quantities of beverages, reducing manual operation time and errors and improving work efficiency. Especially at large-scale events, sporting events, or catering services, beverage dispensing devices can significantly improve service efficiency and meet the drinking needs of large crowds.

[0003] The beverage dispensing device includes a beverage barrel for holding beverages, and a beverage dispenser such as a faucet can be connected to the neck opening of the beverage barrel to achieve beverage dispensing. Existing beverage barrels have a problem of poor sealing, which may cause the beverage to leak or deteriorate.

[0004] To this end, a Chinese patent application (application number: 200620056149.2) discloses a fully sealed water dispenser, comprising an inner liner type water barrel, the water barrel comprising a hard barrel body, a neck for discharging water and a barrel cover, an inner liner being arranged inside the barrel body, and an air vent being arranged at a central depression at the bottom of the barrel body to meet the air intake required for the inner liner to shrink and release water, the air vent having a filtering structure for blocking impurities, the inner liner comprising a barrel body made of a flexible film and a barrel opening sealed to the barrel body, the outer diameter of the barrel opening being smaller than the inner diameter of the neck opening and being indirectly or directly fixed to the inner wall of the neck opening, an air gap being left between the outer wall of the barrel opening and the inner wall of the neck opening, the barrel cover comprising a plug therein to make the drinking water in the barrel clean and easy to connect to the water dispenser conduit.

[0005] However, the above method has the following defects: an inner liner is arranged in the barrel body, and at the same time, the liner body and the liner opening are sealed and fixed, and the liner opening and the neck opening are sealed and fixed, an air gap must be left between the outer wall of the liner opening and the inner wall of the neck opening. The structure is relatively complex, the design and manufacturing complexity is high, and the cost is high. Utility Model Content

[0006] The purpose of the present invention is to solve the above problems in the existing technology and to propose a beverage barrel. The technical problem to be solved by the present invention is: how to make the beverage barrel structure simple and reduce the cost.

[0007] The purpose of the utility model can be achieved through the following technical solutions: a beverage barrel, comprising a barrel body, the top of the barrel body protruding outward to form a neck, the neck is connected to a barrel cover, and the bottom of the barrel body is provided with an exhaust hole, characterized in that the bottom of the barrel body is also provided with a sealing plug for sealing the exhaust hole, the barrel cover comprises a sealing sheet, a plate-shaped base and a cylindrical sealing portion, the base is respectively connected to the outer edge of the sealing sheet and the side wall of the sealing portion, the sealing portion is sealed with the neck, and the tensile strength of the sealing sheet is less than the tensile strength of the base.

[0008] The base is in the shape of a hollow plate, the inner side of the base is connected to the outer edge of the sealing sheet to form the top surface of the barrel cover, and the outer side of the base is connected to the side wall of the sealing portion, and the sealing portion forms the side of the barrel cover. Specifically, the sealing sheet, the base and the sealing portion can be processed in an integrated manner. The cylindrical sealing portion is adapted to the shape of the cylindrical neck, and the barrel cover is sealed and connected to the neck via the sealing portion. Specifically, a threaded connection can be adopted. The sealing plug can block the exhaust hole, and through the cooperation of the sealing plug and the exhaust hole, the gas in the inner cavity of the barrel body can be isolated from or connected to the external cavity. Through the cooperation of the sealing plug and the exhaust hole, during the storage and transportation of the liquid, the gas in the inner cavity of the barrel body can be isolated from the external air to prevent liquid leakage or gas entry. When it is necessary to draw out the liquid, the gas in the inner cavity of the barrel body can be connected to the external air, and the air pressure in the inner cavity of the barrel body can be flexibly adjusted so that the liquid can flow out smoothly. During the storage and transportation of liquids, the barrel lid, connected to the neck, acts as a seal. This means that when the sealing sheet is connected to the base, it ensures the barrel's seal, preventing liquid leakage or gas intrusion. When the liquid needs to be drawn out, the sealing sheet is punctured or torn off to create a liquid outlet. This results in a simple structure and low cost. Because the tensile strength of the sealing sheet is less than that of the base, meaning it is more easily torn or punctured than the base, force can be applied to the sealing sheet, easily puncturing or tearing it to create a liquid outlet without damaging the base. This facilitates rapid liquid withdrawal and facilitates convenient operation.

[0009] In the beverage barrel described above, the sealing sheet is thinner than the base. The base, a major structural component of the barrel lid, is thicker and primarily provides structural support. During storage and transportation, the base provides sturdy support and, together with the sealing sheet, maintains a tight seal within the barrel, preventing leakage or gas ingress. The thin sealing sheet design makes it easier to puncture or tear the sealing sheet with minimal force when liquid needs to be removed, thus conveniently creating a liquid or gas passage.

[0010] In the beverage barrel, the edge of the sealing sheet is recessed to form an annular groove 1. The provision of groove 1 weakens the connection between the sealing sheet and the base. When force is applied to the sealing sheet, groove 1 becomes the most vulnerable point on the top surface. Even a relatively small force can separate the sealing sheet from the base around groove 1, forming a clear liquid passage.

[0011] In the beverage barrel described above, the opening of groove one faces the barrel inner cavity, the top surface of the barrel lid is recessed into the barrel inner cavity to form groove two, and the bottom of groove two is formed by a sealing sheet. The opening of groove one faces the barrel inner cavity, preventing external dust and debris from accumulating within groove one and entering the barrel inner cavity upon puncturing or tearing the sealing sheet, thereby contaminating the liquid. The recess of groove two into the barrel inner cavity, i.e., the sealing sheet is recessed into the barrel inner cavity relative to the base, helps protect the sealing sheet, prevents it from being directly impacted by external forces during transportation and fixing, and helps ensure the sealing and overall structural integrity.

[0012] In the beverage barrel mentioned above, the inner side surface of the sealing portion is pressed against the outer side surface of the neck, and the barrel cover also includes a sealing ridge extending into the neck, and the sealing ridge includes a connecting section and a yielding section, the outer side surface of the connecting section forms a gap with the inner side surface of the neck, the outer side surface of the yielding section is an arc surface and is pressed against the inner side surface of the neck, and the end of the yielding section forms a gap with the neck. The yielding section is designed to be an arc surface and to form a gap with the neck at the end, which reduces the alignment requirements and is conducive to the convenient and quick installation of the barrel cover and the neck. At the same time, the outer side surface of the connecting section forms a gap with the inner side surface of the neck, and the outer side surface of the yielding section is designed to be an arc surface, which can adapt to slight deformation or asymmetry of the barrel cover, allow certain processing errors, and also allow slight deformation during use.

[0013] In the beverage barrel, the outer surface of the sealing portion protrudes outward to form a strip-shaped guide block and a strip-shaped limit block. The guide block includes a guide section and an L-shaped limit section. The guide section gradually tilts along the circumferential direction from the base toward the barrel body. One end of the limit section connected to the guide section extends along the circumferential direction, and the other end extends along the axial direction. The limit block extends along the axial direction, and an installation space is formed between the limit block and the guide block. The guide section and the limit section have a smooth transition. The installation space left between the limit block and the guide block is conducive to quickly and accurately aligning a beverage dispenser such as a faucet with the neck. The guide section is conducive to reducing friction and resistance when installing a beverage dispenser such as a faucet. The limit section can prevent the neck from being over-inserted, resulting in liquid leakage or component damage.

[0014] In the beverage barrel, the bottom of the barrel body is recessed into the inner cavity to form a groove three, and the vent and sealing plug are located at the bottom of the groove three. The bottom of the barrel body is recessed into the inner cavity to form a groove three, and the vent and sealing plug are located at the bottom of the groove three without protruding from the notch of the groove three. The barrel body surface is flat and easy to transport. At the same time, the design of groove three places the vent and sealing plug in a safer position, reducing damage caused by friction or external impact, and improving durability and service life.

[0015] The beverage barrel mentioned above is further provided with a vent flange at the bottom of the barrel body, and the vent flange includes a connecting portion and a vent portion, the connecting portion passes through the exhaust hole and is threadedly connected to the sealing plug, and the vent flange is provided with gas channels respectively passing through the connecting portion and the vent portion, and the gas channels are respectively connected to the inner cavity of the barrel body and the exhaust hole. The vent flange provides a special ventilation path through the gas channel to ensure that the gas in the barrel body can be discharged or circulated smoothly. This helps to maintain the gas pressure balance inside the barrel body. At the same time, different vent flanges can be replaced to adapt to different gas flow and pressure requirements, thereby improving applicability.

[0016] Compared with the existing technology, this beverage barrel has the following advantages:

[0017] 1. In this beverage barrel, the sealing plug and the exhaust hole cooperate to isolate the gas in the barrel cavity from the outside air during the storage and transportation of the liquid, preventing liquid leakage or gas entry. When the liquid needs to be drawn out, the gas in the barrel cavity can be connected to the outside air, and the air pressure in the barrel cavity can be flexibly adjusted to allow the liquid to flow out smoothly.

[0018] 2. In this beverage barrel, during the storage and transportation of liquid, the barrel cover is connected to the neck to play a sealing role, that is, when the sealing sheet is connected to the base, it can ensure the sealing of the barrel body to prevent liquid leakage or gas from entering. When the liquid needs to be drawn out, the sealing sheet is punctured or torn off to obtain the liquid outlet channel. The structure is simple and the cost is low.

[0019] 3. In this beverage barrel, since the tensile strength of the sealing sheet is less than that of the base, that is, the sealing sheet is more easily torn or punctured than the base, force can be applied to the sealing sheet to easily poke or tear the sealing sheet to create a liquid outlet channel without damaging the base, which helps to quickly draw out the liquid and facilitates convenient operation.

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] 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.

[0031] Example 1:

[0032] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, the beverage barrel comprises a barrel body 1 , the top of the barrel body 1 protrudes outward to form a neck 2 , and the neck 2 is connected to a barrel cover 3 .

[0033] The barrel cover 3 includes a sealing piece 3a, a plate-shaped base 3b and a cylindrical sealing portion 3c. The cylindrical sealing portion 3c is adapted to the shape of the cylindrical neck 2. The inner side surface of the sealing portion 3c is pressed against the outer side surface of the neck 2. The barrel cover 3 is sealed and connected to the neck 2 via the sealing portion 3c. Specifically, a threaded connection is adopted. The base 3b is hollow and plate-shaped. Specifically, the base 3b is annular. The inner side of the base 3b is connected to the outer edge of the sealing piece 3a to form the circular top surface of the barrel cover, and the outer side of the base 3b is connected to the side wall of the sealing portion 3c. The sealing portion 3c forms the side of the barrel cover. Specifically, the sealing piece 3a, the base 3b and the sealing portion 3c can be processed in an integrated manner.

[0034] The thickness of sealing sheet 3a is thinner than that of base 3b, and its tensile strength is also lower than that of base 3b. Base 3b is a key structural component of the end surface of barrel lid 3. Its thickness is relatively thick, primarily providing structural support. During storage and transportation, base 3b provides sturdy support and, together with sealing sheet 3a, maintains the seal of the liquid within the barrel, preventing leakage or gas ingress. The thin design of sealing sheet 3a makes it easier to puncture or tear sealing sheet 3a with minimal force when liquid needs to be removed, thus conveniently creating a liquid or gas passage.

[0035] Furthermore, the sealing sheet 3 a may be made of a material with a relatively low tensile strength, and the base portion 3 b may be made of a material with a relatively high tensile strength.

[0036] The edge of the sealing sheet 3a is recessed to form an annular groove 3a1. The presence of groove 3a1 weakens the connection between the sealing sheet 3a and the base 3b. When force is applied to the sealing sheet 3a, groove 3a1 becomes the most vulnerable spot on the top surface. Even a relatively small force can separate the sealing sheet 3a from the base 3b around groove 3a1, forming a clear liquid passage.

[0037] The opening of groove 1 (3a1) faces the interior of barrel body 1. The top surface of lid 3 is recessed into the interior of barrel body 1 to form groove 2 (6). The bottom of groove 2 (6) is formed by sealing sheet 3a. The opening of groove 1 (3a1) faces the interior of barrel body 1, preventing external dust and debris from accumulating within groove 1 (3a1) and entering the interior of barrel body 1 by puncturing or tearing sealing sheet 3a, thereby contaminating the liquid. The recess of groove 2 (6) into the interior of barrel body 1, i.e., the recess of sealing sheet 3a relative to base 3b, helps protect sealing sheet 3a from direct impact from external forces during handling and securing, thereby ensuring the seal and overall structural integrity.

[0038] The barrel cover 3 also includes a sealing ridge 3d that extends into the neck 2. The sealing ridge 3d includes a connecting section 3d1 and a relief section 3d2. The outer side surface of the connecting section 3d1 forms a gap with the inner side surface of the neck 2. The outer side surface of the relief section 3d2 is a curved surface and abuts against the inner side surface of the neck 2. The end of the relief section 3d2 forms a gap with the neck 2. The relief section 3d2 is designed as a curved surface and forms a gap with the neck 2 at the end, which reduces the alignment requirements and facilitates the convenient and quick installation of the barrel cover 3 and the neck 2. At the same time, the outer side surface of the connecting section 3d13d1 forms a gap with the inner side surface of the neck 2. The outer side surface of the relief section 3d2 is designed as a curved surface, which can accommodate slight deformation or asymmetry of the barrel cover 3, allow for certain processing errors, and also allow for slight deformation during use.

[0039] The outer surface of the sealing portion 3c protrudes outward to form a strip-shaped guide block 7 and a strip-shaped limit block 8. The guide block 7 includes a guide section 7a and an L-shaped limit section 7b. One end of the guide section 7a extends all the way to the base 3b, and the other end gradually tilts from the base 3b toward the barrel body 1 in the circumferential direction. The limit section 7b bends from the base 3b toward the barrel body 1. Specifically, the limit section 7b extends in the circumferential direction at one end connected to the guide section 7a, and extends in the axial direction at the other end. The limit block 8 extends all the way to the base 3b at one end, and extends in the axial direction from the base 3b toward the barrel body 1 at the other end. An installation space is formed between the limit block 8 and the guide block 7. The smooth transition between the guide section 7a and the limit section 7b and the installation space left between the limit block 8 and the guide block 7 facilitates quick and accurate alignment of a beverage dispenser such as a faucet with the neck 2. The guide section 7a helps reduce friction and resistance when installing a beverage dispenser such as a faucet, and the limit section 7b prevents excessive insertion of the neck 2, which may cause liquid leakage or component damage.

[0040] The bottom of the barrel body 1 is provided with a vent 4 and a sealing plug 5 for sealing the vent 4. The bottom of the barrel body 1 is recessed into the inner cavity to form a groove 39, and the vent 4 and sealing plug 5 are located at the bottom of the groove 39. The bottom of the barrel body 1 is recessed into the inner cavity to form a groove 39. The vent 4 and sealing plug 5 are located at the bottom of the groove 39 and do not protrude from the groove 39. The surface of the barrel body 1 is flat, making it easy to transport. At the same time, the design of the groove 39 places the vent 4 and sealing plug 5 in a safer position, reducing damage caused by friction or external impact, and improving durability and service life.

[0041] The bottom of groove three 9 is also provided with a vent flange 10, which includes a connecting portion 10a and a vent portion 10b. The connecting portion 10a passes through the exhaust hole 4 and is threadedly connected to the sealing plug 5. The vent flange 10 is provided with a gas channel 11 that passes through the connecting portion 10a and the vent portion 10b respectively, and the gas channel 11 is connected to the inner cavity of the barrel body 1 and the exhaust hole 4 respectively. When the connecting portion 10a is tightened with the sealing plug 5, the sealing plug 5 and the bottom of groove three 9 clamp the sealing ring, the gas channel 11 is in a blocked state, and the gas in the inner cavity of the barrel body 1 is isolated from the outside air. When the connecting portion 10a is loosened with the sealing plug 5, a gap is formed between the sealing plug 5 and the bottom of groove three 9, and a gap is formed between the external thread of the connecting portion 10a and the internal thread of the sealing plug 5. The gas channel 11 is in a connected state, and the gas in the inner cavity of the barrel body 1 is connected to the outside air.

[0042] By cooperating with the sealing plug 5 and the exhaust hole 4, during the storage and transportation of the liquid, the gas in the inner cavity of the barrel body 1 can be isolated from the outside air to prevent liquid leakage or gas from entering. When it is necessary to draw out the liquid, the gas in the inner cavity of the barrel body 1 can be connected to the outside air, and the air pressure in the inner cavity of the barrel body 1 can be flexibly adjusted so that the liquid can flow out smoothly. During the storage and transportation of the liquid, the barrel cover 3 is connected to the neck 2 to play a sealing role, that is, when the sealing piece 3a is connected to the base 3b, the sealing performance of the barrel body 1 can be guaranteed to prevent liquid leakage or gas from entering. When it is necessary to draw out the liquid, the sealing piece 3a can be punctured or torn off to obtain a liquid outlet channel. The structure is simple and the cost is low. Since the tensile strength of the sealing piece 3a is less than the tensile strength of the base 3b, that is, the sealing piece 3a is more easily torn or punctured relative to the base 3b, force can be applied to the sealing piece 3a, and the sealing piece 3a can be easily punctured or torn to produce a liquid outlet channel without damaging the base 3b, which helps to achieve rapid liquid drawing and is conducive to convenient operation.

[0043] Example 2:

[0044] The technical solution in this embodiment is basically the same as the technical solution in embodiment one, except that, in this embodiment, a diaphragm capable of blocking the exhaust hole 4 is provided at the bottom of groove three 9, and the tensile strength of the diaphragm is less than the tensile strength of the bottom of groove three 9.

[0045] During storage and transportation of liquids, the diaphragm blocks the vent 4, isolating the gas in the barrel 1 from the outside air and preventing liquid leakage or gas ingress. When liquid needs to be drawn out, the diaphragm is punctured or torn off to access the gas passage 11, connecting the gas in the barrel 1 with the outside air. The air pressure in the barrel 1 can be flexibly adjusted, allowing the liquid to flow out smoothly.

[0046] Although this document frequently uses terms such as barrel body 1, neck 2, barrel cover 3, sealing piece 3a, groove 1 3a1, base 3b, sealing portion 3c, sealing ridge 3d, connecting section 3d1, retracting section 3d2, vent 4, sealing plug 5, groove 2 6, guide block 7, guide section 7a, limiting section 7b, limiting block 8, groove 3 9, vent flange 10, connecting portion 10a, vent portion 10b, and gas passage 11, the use of other terms is not excluded. These terms are used solely to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitations would be contrary to the spirit of the present invention.
