Description

Technical Field

[0001] This invention relates to the field of wine bottle technology, specifically to a self-heating packaging bottle. Background Technology

[0002] Yellow wine, a traditional Chinese brewed alcoholic beverage, boasts a long history and rich cultural connotations. It typically needs to be heated to achieve its optimal flavor, with an ideal serving temperature between 35℃ and 45℃. Within this temperature range, the wine's flavor is more mellow, its aroma more fragrant, and its health benefits are better realized. Traditional methods of warming yellow wine, such as double-boiling or microwave heating, are not only cumbersome and time-consuming but also require numerous tools. Newer methods, like warming pots and electric warmers, are usually bulky and rely on external power or heat sources. These methods fail to meet consumers' needs for portable and immediate warming of yellow wine in outdoor or travel settings.

[0003] Therefore, there is an urgent need for a self-heating packaging bottle that is simple in structure, easy to use, and portable. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a self-heating packaging bottle. By incorporating an openable water-flow mechanism, water from the storage chamber can flow into the heating chamber, reacting with the heating pack to generate heat and thus heating the rice wine inside the bottle. This eliminates the need for additional warming equipment, and the bottle is simple in structure, easy to use, and portable.

[0005] To achieve the above objectives, the present invention provides the following solution: A self-heating packaging bottle includes a bottle body, a heating element, and a water-circulating mechanism. The water-circulating mechanism is connected to the bottle body. The heating element is disposed at the bottom of the bottle body. The bottle body includes an inner bottle body and an outer bottle body, and a water storage cavity is formed between the inner bottle body and the outer bottle body. The heating element has a heating cavity for placing a heating pack. When the water-circulating mechanism is turned on, water in the water storage cavity flows into the heating cavity through the water-circulating mechanism.

[0006] Preferably, the outer bottle body includes an upper bottle body and a lower bottle body, and the upper bottle body and the lower bottle body are detachably connected.

[0007] Preferably, the lower bottle body has an inner sleeve, which is through at both the top and bottom. The lower end of the inner sleeve is connected to the heating chamber. The inner sleeve accommodates the lower end of the inner bottle body, and the outer peripheral wall of the inner bottle body is sealed to the inner peripheral wall of the inner sleeve.

[0008] Preferably, the water-passing mechanism includes a first water-passing hole disposed at the bottom of the water storage chamber, a sealing plate, a rotating body, and a second water-passing hole disposed on the sealing plate. The rotating body is fixedly connected to the sealing plate and rotatably connected to the bottle body. In the initial state, the first water-passing hole and the second water-passing hole are misaligned. By rotating the rotating body, the first water-passing hole and the second water-passing hole are switched to an aligned state, thereby realizing the opening of the water-passing mechanism.

[0009] Preferably, the heating element and the bottle body are rotatably connected, and the heating element and the rotating body are connected by a transmission.

[0010] Preferably, the rotating body is an annular plate, the top of the annular plate is connected to the sealing plate, the outer wall of the annular plate is provided with a protrusion, and the inner wall of the heating part is provided with a recess that matches the protrusion, and the protrusion is embedded in the recess.

[0011] Preferably, the outer bottle body extends downwards with a first extension plate, the inner wall of the first extension plate being in contact with the outer wall of the annular plate.

[0012] Preferably, the side wall of the heating part is provided with an exhaust hole.

[0013] Preferably, the side wall of the first extension plate is provided with a first vent hole, the side wall of the annular plate is provided with a second vent hole, the annular plate extends downward to provide a second extension plate, the protrusion is provided on the outer wall of the second extension plate, the inner bottom of the heating part is provided with a cylinder, the inner cavity of the cylinder is used to place a heating pack, the top of the cylinder is open, and the notch is provided at the top of the cylinder. In the initial state, the first vent hole and the second vent hole are misaligned, and the first vent hole and the second vent hole are aligned by rotating the annular plate.

[0014] Preferably, the inner wall of the first extension plate is provided with a slot, and the outer wall of the annular plate is provided with a locking block that matches the slot. When the annular plate is rotated, the slot and the locking block engage. When the slot and the locking block are engaged, the first water passage hole and the second water passage hole are aligned.

[0015] The present invention achieves the following main technical effects compared to the prior art: The self-heating packaging bottle disclosed in this invention has an openable water-passing mechanism that allows water in the water storage chamber to flow into the heating chamber, react with the heating pack to generate heat, and heat the rice wine in the bottle. No additional wine warming equipment is needed. It has a simple structure, is easy to use, and is easy to carry.

[0016] The other technical solutions of this invention achieve the following technical effects compared to the prior art: The upper and lower bottle bodies are detachably connected, making them easy to manufacture and convenient for filling the water storage chamber.

[0017] The rotating heating element drives the rotating body to rotate, thereby aligning the misaligned water passages and allowing water in the storage chamber to flow into the heating chamber. This simple operation allows hot air to enter the storage chamber through the water passages and heat the rice wine inside the bottle from the side wall, increasing the heating surface of the rice wine and improving heating efficiency.

[0018] When not heated, the heating pack inside the cylinder is isolated from the outside environment, which can effectively prevent humid air from entering the cylinder and prevent the heating pack from failing due to moisture absorption.

[0019] By engaging the slot and the block, the first and second water passages are precisely aligned, eliminating human alignment errors, ensuring reliable water flow, and making the operation simple and efficient. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] The purpose of this invention is to provide a self-heating packaging bottle. By setting an openable water-passing mechanism, water in the water storage chamber can flow into the heating chamber, react with the heating pack to generate heat, and heat the rice wine in the bottle. No additional wine warming equipment is needed. The structure is simple, easy to use, and portable.

[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] refer to Figures 1-5 The self-heating packaging bottle disclosed in this embodiment includes a bottle body 1, a heating part 4, and a water-passing mechanism. The water-passing mechanism is connected to the bottle body 1, and the heating part 4 is disposed at the bottom of the bottle body 1. The bottle body 1 includes an inner bottle body 2 and an outer bottle body 3, and a water storage cavity 5 is formed between the inner bottle body 2 and the outer bottle body 3. The heating part 4 has a heating cavity for placing a heating pack. In the initial state, the water-passing mechanism is in the closed state and can be opened manually. After the water-passing mechanism is opened, the water in the water storage cavity 5 flows into the heating cavity through the water-passing mechanism and reacts with the heating pack to generate heat. The hot air contacts the bottom of the inner bottle body 2 to heat the rice wine in the bottle. No additional wine warming device is required. The structure is simple, easy to use, and easy to carry.

[0026] The outer bottle body 3 includes an upper bottle body 6 and a lower bottle body 7. Dividing the outer bottle body 3 into an upper bottle body 6 and a lower bottle body 7 facilitates manufacturing and also makes it easy to fill water into the water storage chamber 5. The inner peripheral wall of the upper bottle body 6 is provided with internal threads, and the outer peripheral wall of the lower bottle body 7 is provided with external threads. The upper bottle body 6 and the lower bottle body 7 are connected by threads. In another embodiment, the upper bottle body 6 and the lower bottle body 7 can also be detachably connected by a snap fastener. To improve the sealing performance, a sealing ring can be provided at the connection between the upper bottle body 6 and the lower bottle body 7.

[0027] The lower bottle body 7 has an inner sleeve 8, which is through-hole at both the top and bottom. The lower end of the inner sleeve 8 is connected to the heating chamber. The inner sleeve 8 accommodates the lower end of the inner bottle body 2. The lower end of the inner bottle body 2 can be extended to pass through the inner sleeve 8, which increases the volume of the inner bottle body 2 and can hold more rice wine. At the same time, it also shortens the distance from the bottom of the inner bottle body 2 to the bottom of the heating part 4, so that the hot air can fully contact the bottom of the inner bottle body 2 and improve the heating efficiency. The outer peripheral wall of the inner bottle body 2 is sealed to the inner peripheral wall of the inner sleeve 8 to prevent water in the water storage chamber 5 from flowing into the heating chamber along the outer wall of the inner bottle body 2.

[0028] The water passage mechanism includes a first water passage hole at the bottom of the water storage chamber 5, a sealing plate 9, a rotating body 10, and a second water passage hole 11 on the sealing plate 9. The rotating body 10 is fixedly connected to the sealing plate 9 and rotatably connected to the bottle body 1. In the initial state, the first water passage hole and the second water passage hole 11 are misaligned, which can block the water from flowing down into the water storage chamber 5. By rotating the rotating body 10, the first water passage hole and the second water passage hole 11 are aligned, so as to open the water passage mechanism. After opening, the water in the water storage chamber 5 flows smoothly into the heating chamber. By rotating the rotating body 10, the misaligned water passage holes are aligned. The operation is simple. At the same time, hot air can enter the water storage chamber 5 from the water passage hole and heat the rice wine in the inner bottle body 2 from the side wall, which increases the heating surface of the rice wine and improves the heating efficiency.

[0029] To increase the sealing performance, a wax seal can be applied at the misalignment of the first water inlet and the second water inlet 11. Initially, the wax seal is sealed. When the rotating body 10 is rotated, the wax seal is broken, and the first water inlet and the second water inlet 11 are connected.

[0030] The heating part 4 is rotatably connected to the bottle body 1, and the heating part 4 is drive-connected to the rotating body 10. By rotating the heating part 4, the rotating body 10 can be rotated, thereby opening the water flow mechanism. The operation is simple. In another embodiment, the heating part 4 and the bottle body 1 can also be fixedly connected, and a lever is fixedly provided on one side of the rotating body 10. An opening is provided on the side wall of the heating part 4, and the lever protrudes from the opening. The rotation of the rotating body 10 is achieved by moving the lever.

[0031] The rotating body 10 is an annular plate, and the top of the annular plate is connected to the sealing plate 9. The outer wall of the annular plate is provided with a protrusion 12, and the inner wall of the heating part 4 is provided with a recess 13 that matches the protrusion 12. The protrusion 12 is embedded in the recess 13. The transmission is more reliable by the interlocking of the protrusion 12 and the recess 13. In another embodiment, pin holes can also be provided on the side wall of the annular plate and the side wall of the heating part 4. After being fixed by a pin shaft, the heating part 4 can transmit the transmission of the annular plate.

[0032] The outer bottle body 3 extends downward with a first extension plate 14. The inner wall of the first extension plate 14 fits against the outer wall of the annular plate. The first extension plate 14 limits the annular plate radially, effectively preventing radial relative displacement between the outer bottle body 3 and the annular plate, thus improving the overall integrity of the structure.

[0033] A first horizontal ridge is provided on the inner side wall of the first extension plate 14, and a second horizontal ridge 22 is provided on the outer side wall of the annular plate. The two plates are interlocked by the first horizontal ridge being below and the second horizontal ridge 22 being above, which can limit the relative displacement of the bottle body 1 and the annular plate in the axial direction, but does not limit the relative rotation in the radial direction. In another embodiment, the rotational connection between the annular plate and the bottle body 1 can also be achieved by the interlocking connection of the slot and the strip.

[0034] To improve the connection stability between the annular plate and the bottle body 1 and further limit the relative axial displacement between the annular plate and the bottle body 1, the side wall of the annular plate and the first extension plate 14 can be set to be inclined inward from top to bottom, or the bottom of the water storage cavity 5 and the sealing plate 9 can be set to be inclined inward from bottom to top.

[0035] To prevent excessive pressure from being generated inside the heating chamber, an exhaust port 15 can be provided on the side wall of the heating part 4.

[0036] The first extension plate 14 has a first vent hole 16 on its side wall, and the annular plate has a second vent hole 17 on its side wall. The annular plate extends downward to form a second extension plate 18. A protrusion 12 is provided on the outer wall of the second extension plate 18. A cylinder 19 is provided at the bottom of the heating part 4. A heating pack is placed in the inner cavity of the cylinder 19. The top of the cylinder 19 is open, and a notch 13 is provided at the top of the cylinder 19. In the initial state, the first vent hole 16 and the second vent hole 17 are misaligned. The heating pack inside the cylinder 19 is isolated from the outside world, which can effectively prevent the outside humid air from entering the cylinder 19 and prevent the heating pack from failing due to moisture absorption. By rotating the annular plate, the first vent hole 16 and the second vent hole 17 are aligned, and hot air can be released to the outside world through the first vent hole 16, the second vent hole 17 and the exhaust hole 15.

[0037] The inner wall of the heating part 4 is provided with a support plate 20, and the inner wall of the support plate 20 is provided with a vertical exhaust groove 21. The hot air released from the first exhaust hole 16 and the second exhaust hole 17 passes through the exhaust groove 21 and is discharged from the exhaust hole 15.

[0038] The outer wall of the first extension plate 14 abuts against the top of the support plate 20, providing effective support for the bottle body 1 and the rotating body 10, preventing the entire weight of the upper part from being borne by the protrusion 12, and improving the stability of the structure.

[0039] The outer side wall of the first extension plate 14 is provided with a first diagonal groove 23, and the inner side wall of the support plate 20 is provided with a second diagonal groove 24. They are interlocked by the first diagonal groove 23 being below and the second diagonal groove 24 being above. The heating part 4 and the bottle body 1 are rotated and fastened by rotating the heating part 4. In another embodiment, the heating part 4 and the bottle body 1 can also be rotated and fastened by a threaded connection.

[0040] The inner wall of the first extension plate 14 is provided with a slot, which is formed by two vertical locking strips spaced a certain distance apart. The outer wall of the annular plate is provided with a locking block that matches the slot. The outer surfaces of the locking block and the near vertical locking strip are both arc-shaped, which facilitates the locking block to slide smoothly into the slot. The far vertical locking strip is a quadrangular prism, and its outer surface has convex edges, which helps to restrict the movement of the locking block. The annular plate has a certain deformation capacity and can recover after deformation. When the annular plate is rotated, the locking block first contacts the near vertical locking strip. At this time, the operator will feel a certain damping sensation. If the heating part 4 is rotated further, the annular plate will deform, and the arc surface of the locking block will contact the arc surface of the near vertical locking strip. The locking block will slide smoothly into the slot along the arc surface of the near vertical locking strip and be restricted in movement by the far vertical locking strip. The annular plate will return to its original shape. At this time, the operator can no longer rotate the heating part 4, and the slot and the locking block will engage. When the annular plate is rotated in the reverse direction, the locking block can slide out from the slot, allowing children to play with the empty bottle. When the slot and the locking block are engaged, the first water inlet and the second water inlet 11 are aligned. When the self-heating bottle has a first vent 16 and a second vent 17, the first vent 16 and the second vent 17 are also aligned. Initially, the slot and the locking block are not engaged. After rotating the heating unit 4, the slot and the locking block engage, achieving precise alignment of the first water inlet and the second water inlet 11, eliminating human alignment errors, ensuring reliable water flow, and making operation simple and efficient.

[0041] The heating pack can be a calcium oxide heating pack.

[0042] The outer wall of bottle 1 is equipped with a rotation direction indicator to provide operation guidance for the operator.
