Description

Technical Field

[0001] This invention belongs to the field of beverage packaging technology, specifically a beverage bottle cap, bottle body, and easy-to-assemble ready-to-use beverage bottle and its filling method. Background Technology

[0002] Honey water is popular among consumers because of its sweet and mild taste, non-irritating properties, and gentle effects such as soothing the throat, nourishing the stomach, and promoting bowel movements. It quickly replenishes fluids and energy, and its natural and healthy nature makes it a favorite. However, honey contains yeast. If honey is directly mixed with water to make honey water, the yeast can easily multiply, causing the honey water to ferment, turn sour, and produce gas. Studies have shown that honey mixed with water can only be stored for 1-2 days at room temperature. Therefore, preservatives are often added to prevent spoilage.

[0003] Currently, some ready-to-use honey water bottle caps have appeared on the market, used to store honey and water separately, allowing for immediate preparation and consumption. This effectively preserves the natural flavor and nutrients of honey, and requires no additives, making it healthier. However, existing ready-to-use honey water bottle caps have the following drawbacks: 1) The cap structure is complex and difficult to assemble. Furthermore, the assembly of various components and the honey filling process often need to be carried out simultaneously, increasing the difficulty of honey filling and raising production costs; 2) They generally use plastic film to seal the honey compartment, requiring the pointed part of the cap to pierce the plastic film to release the honey into the bottle. During this process, debris is easily generated, which can enter the beverage, posing a safety hazard. Summary of the Invention

[0004] The purpose of this invention is to provide a beverage bottle cap, bottle body, and easy-to-assemble ready-to-use beverage bottle and its filling method. The structure is simple, the assembly is convenient, and the filling difficulty and production cost are significantly reduced.

[0005] This invention is achieved through the following technical solution: A beverage bottle cap, comprising a bottom cap and a top cap; The lower cover includes an integrally formed neck and a lower cover body. The neck is provided with external threads. The lower cover body includes an outer cover. The inner surface of the outer cover is provided with an internal thread that matches the external thread on the upper outer surface of the neck. An inner cover is integrally formed inside the outer cover and is coaxially arranged with it. The inner cover has a hollow structure and is connected to the neck. A sealing element is fixedly connected to the lower end of the inner cover. The upper cover has an internal thread that matches the external thread of the neck.

[0006] Furthermore, the lower end of the upper cover is connected to an anti-theft ring, and several evenly distributed limiting blocks are fixedly installed inside the anti-theft ring; The neck of the lower cover is integrally formed with an annular protrusion for locking the limiting block.

[0007] Furthermore, the sealing element is an aluminum foil film adhered to the bottom of the inner cover, and the connection between the sealing element and the inner cover is reinforced along 1 / 6 to 1 / 5 of its outer circumference.

[0008] Furthermore, the outer surface of the outer cover is provided with dense anti-slip grooves along its circumference.

[0009] A bottle body includes a bottle body and a bottle neck integrally formed therewith. The upper outer surface of the bottle neck is provided with external threads, and the inside of the bottle neck is integrally formed with an annular fold, with the end of the annular fold facing upward.

[0010] Furthermore, at least one water inlet is provided on the annular folded edge.

[0011] Furthermore, the port of the annular fold is flat or beveled, and the top of the port is planar, serrated, or wavy.

[0012] An easy-to-assemble ready-to-use beverage bottle includes the cap and bottle body, as well as a tear-off ring and a sealing structure; The tear ring is connected to the lower end of the outer cover, and the tear ring has a fracture opening. The inner surface of the tear ring is integrally formed with several evenly distributed protruding teeth. The lower end of the bottleneck has an integrally formed annular flange for limiting the hand-tear ring and several evenly distributed stop blocks that can engage with the protruding teeth along its circumference. The sealing structure includes an annular groove and an annular ridge, wherein: the annular groove is formed on the outer surface of the upper end of the bottleneck, and the annular ridge is fixedly set on the inner surface of the outer cover and located above the internal thread, and the annular ridge can be engaged inside the annular groove.

[0013] Furthermore, the stop block is triangular in shape, and the surface that contacts the inner surface of the tear ring is arc-shaped.

[0014] A filling method for an easy-to-assemble ready-to-use beverage bottle includes the following steps: Step 1: First, fill the bottle with water, then screw the cap clockwise to connect it to the bottle neck with threads until the lower end of the tear ring contacts the upper surface of the ring flange, thus completing the assembly of the cap and the bottle. Step 2: Pour the honey into the inner cap from the neck of the lower cap, then thread the upper cap onto the neck of the lower cap to seal the top of the lower cap, completing the honey filling process.

[0015] The present invention has the following beneficial technical effects: This invention features a double-layered cap structure comprising an inner and outer cap. The outer cap is threaded into the bottle neck, allowing the inner cap to extend into the neck as a honey storage compartment. A ring-shaped folded edge, positioned inside the bottle neck with its port facing upwards, replaces the traditional sharp point of the cap. When the cap is screwed on, the ring-shaped folded edge pushes upwards to break the seal at the bottom of the inner cap, allowing honey to flow. This invention offers several advantages: First, compared to existing ready-to-drink beverage bottles, it simplifies the cap structure, enabling one-step assembly of the cap and bottle body, thus simplifying the assembly process. Second, compared to using a sharp point to pierce the seal, the ring-shaped folded edge breaks the seal circumferentially upwards, resulting in a more dispersed and even force, reducing debris generation and improving safety. Third, honey water preparation is achieved simply by screwing on the cap, making the operation simple and effortless. In summary, this invention reduces assembly difficulty, facilitates streamlined filling processes, significantly reduces production costs, and provides greater convenience for users.

[0016] By creating a water inlet on the ring-shaped fold, honey and water trapped between the inner wall of the bottle neck and the ring-shaped fold can flow into the bottle body, reducing waste.

[0017] Setting the port of the annular fold to an angled opening other than a flat opening makes it easier to break through the seal. Furthermore, setting the top of the port of the annular fold to a serrated or wavy shape other than a flat surface can significantly improve the breaking efficiency.

[0018] The seal uses aluminum foil film, which effectively reduces debris generation compared to plastic film, improving drinking safety. Additionally, the connection between the seal and the inner cap is reinforced along 1 / 6 to 1 / 5 of its outer circumference. Even when the annular fold breaks the seal upwards, the reinforced connection between the inner cap and the seal will not break, ensuring the seal remains connected to the inner cap and flips upwards, preventing it from falling into the bottle and further enhancing drinking safety.

[0021] The present invention will be further described in detail below with reference to specific embodiments. This is an explanation of the present invention and not a limitation thereof.

[0022] like Figures 1-10 As shown, an easy-to-assemble ready-to-use beverage bottle includes a beverage cap, a bottle body, a tear-off ring, and a sealing structure. like Figures 1-2 and Figures 6-9 As shown, the bottle body includes a bottle body 1 and a bottle neck 11 integrally formed therewith. The upper outer surface of the bottle neck 11 is provided with external threads. The inside of the bottle neck 11 is integrally formed with an annular flange 12, and the port of the annular flange 12 faces upward. The lower outer surface of the bottle neck 11 is integrally formed with an annular flange 14 and a number of evenly distributed stop blocks 13 along its circumference, and the stop blocks 13 are located above the annular flange 14. like Figures 1-4 As shown, the beverage bottle cap includes a lower cap 2 and an upper cap 3. The lower cap 2 includes an integrally formed neck and a lower cap body. The neck is provided with external threads. The lower cap body includes an outer cap. The inner surface of the outer cap is provided with an internal thread that matches the external thread on the upper outer surface of the bottle neck 11, so that the lower cap 2 can be threadedly connected to the bottle neck 11. An inner cap 21 is integrally formed inside the outer cap and is coaxially arranged with it. The inner cap 21 has a hollow structure and is connected to the neck. A sealing element 22 is fixedly connected to the lower end of the inner cap 21. The inner cap 21 and the neck can work together to serve as a honey storage compartment for honey. like Figure 2 and Figure 4As shown, the tear ring 4 is connected to the lower end of the outer cover. The inner surface of the tear ring 4 has several evenly distributed protrusions 41 integrally formed. These protrusions 41 can engage with the end face of the stop block 13. When the lower cover 2 is turned counterclockwise, the stop block 13 limits the protrusions 41, preventing the tear ring 4 from moving upwards with the lower cover 2. If the lower cover 2 is continued to be turned counterclockwise, the connection point between the outer cover and the tear ring 4 will break, allowing consumers or merchants to promptly detect that the lower cover 2 has been opened. When the lower cover 2 is turned clockwise, the tear ring 4 must be removed first; otherwise, the tear ring 4 will limit the lower cover 2, preventing it from moving downwards. When the tear ring 4 is torn off, the lower cap 2 is turned clockwise to move it to the lowest position. The annular fold 12 presses the seal 22 upward, thereby puncturing it and allowing the honey stored inside the inner cap 21 to flow out from the bottom of the inner cap 21 and into the bottle body 1. By setting the tear ring 4 to position the lower cap 2, it can prevent the seal 22 from being broken due to excessive twisting during the filling process. This reduces the precision requirements of the filling machine during the filling process and improves the filling success rate. It can effectively overcome the problems of high beverage bottle scrap rate and large honey water loss caused by the accidental breaking of the seal 22. The sealing structure includes an annular groove and an annular ridge. The annular groove is formed on the upper outer surface of the bottle neck 11, and the annular ridge is fixedly set on the inner surface of the outer cover and located above the internal thread. When the outer cover is threadedly connected to the bottle neck 11 and the lower end face of the tear ring 4 contacts the upper end face of the annular flange 14, the annular ridge is engaged inside the annular groove, which can prevent water inside the bottle body 1 from leaking out from the connection between the outer cover and the bottle neck 11.

[0023] Preferably, the stop block 13 is triangular in shape, and the surface in contact with the inner surface of the tear ring 4 is arc-shaped. During the installation of the lower cover 2, the tear ring 4 can rotate together with the lower cover 2, which can effectively reduce the resistance during the installation process, reduce the scrap rate of the tear ring 4 and the lower cover 2, and reduce the production cost.

[0024] like Figure 1 , Figure 2 and Figure 5 As shown, the upper cover 3 has an internal thread that matches the external thread of the neck, allowing the upper cover 3 to be threadedly connected to the lower cover 2. An anti-theft ring is connected to the lower end of the upper cover 3, and several evenly distributed limiting blocks are fixedly installed inside the anti-theft ring. The neck of the lower cover 2 is integrally formed with an annular boss for locking the limiting blocks. When the upper cover 3 is unscrewed, the limiting blocks are locked in the annular boss, preventing the anti-theft ring from moving upward with the upper cover 3, causing the connection point between the upper cover 3 and the anti-theft ring to break under tension. By setting the anti-theft ring, it is easy for merchants or consumers to discover when the upper cover 3 is opened.

[0025] like Figure 3As shown, the tear ring 4 has a fracture opening 42, which is divided into upper and lower parts. The upper part is L-shaped, in which the two ends of the tear ring 4 are not connected to each other and have a free end for the hand to grip. In the lower part, the two ends of the tear ring 4 are connected by a point. When the consumer holds the free end and tears it, the point connection of the lower part will break, thereby removing the tear ring 4.

[0026] Preferably, the port of the annular folded edge 12 is as follows: Figure 6 The flat opening shown or as Figure 7 The bevel shown is more effective at breaking through the seal than a flat opening.

[0027] Preferably, the top of the port of the annular folded edge 12 is as follows: Figure 6 and Figure 7 The planar shape shown, such as Figure 8 The serrated or as shown Figure 9 The wavy shape shown can be selected according to the material and thickness of the seal 22 during actual production. For example, if the seal 22 is thick and not easily broken, the top of the port of the annular folded edge 12 can be processed into a sharper serrated shape; conversely, if the seal 22 is thin and easily broken, the top of the port of the annular folded edge 12 can be processed into a flat shape.

[0028] Preferred, such as Figure 10 As shown, the annular folded edge 12 has at least one water inlet 15, and the honey and water retained between the inner wall of the neck 11 and the annular folded edge 12 flow into the bottle body 1 from the water inlet 15, reducing waste.

[0029] Preferred, such as Figure 4 As shown, the outer surface of the lower cover 2 is provided with densely distributed vertical anti-slip grooves along its circumference, which can increase the friction between the robotic arm and fingers and the lower cover 2, and facilitate the gripping force of the robotic arm and the consumer's fingers when twisting the lower cover 2 during filling.

[0030] Preferably, the sealing element 22 is an aluminum foil film pasted to the bottom of the inner cover 21. Compared with using a plastic film to seal the bottom of the inner cover, it can effectively reduce the generation of debris, improve drinking safety, and eliminate the sealing process in the filling process, which helps to improve filling efficiency.

[0031] Preferably, the connection between the sealing element 22 and the inner cap is reinforced along 1 / 6 to 1 / 5 of its outer circumference. When the annular fold 12 pushes upward to break through the sealing element 22, the reinforced part between the inner cap and the sealing element 22 will not break, so that the sealing element 22 is connected to the inner cap and flips upward, without falling into the bottle body 1, which helps to improve the consumer's experience.

[0032] A filling method for an easy-to-assemble ready-to-use beverage bottle includes the following steps: Step 1: First, fill the bottle body 1 with water, then screw the cap 2 clockwise to connect it to the bottle neck 11 until the lower end of the tear ring 4 contacts the upper surface of the annular flange 14, thus completing the assembly of the cap 2 and the bottle body 1. Step 2: Pour honey into the inner cap from the neck of the lower cap 2, then thread the upper cap 3 onto the neck of the lower cap 2 to seal the top of the lower cap 2, thus completing the honey filling.

[0033] The working principle of this invention is as follows: During filling: First, fill the bottle body 1 with water, then screw the lower cap 2 clockwise so that its threads connect to the neck 11, until the lower end of the tear ring 4 is caught on the annular flange 14, completing the assembly of the lower cap 2 and the bottle body 1. Then, inject honey from the neck of the lower cap 2 into the inner cap, and then thread the upper cap 3 onto the neck of the lower cap 2. During this process, the anti-theft ring moves down to the lowest position with the upper cap 3, sealing the top of the lower cap 2 through the upper cap 2, thus completing the honey filling. When drinking: First, tear off the tear ring 4, then twist the lower cap 2 clockwise. The lower cap 2 moves downward, so that the seal 22 contacts the top of the annular fold 12. When the lower cap 2 moves downward to the lowest position, the seal 22 is broken upward by the annular fold 12 and flips up. The honey stored inside the lower cap 2 flows out from the bottom of the inner cap and into the bottle body 1. After the honey and water are mixed, the honey water preparation is complete. Then twist the upper cap 3 counterclockwise. Under the blocking effect of the annular protrusion on the limiting block, the anti-theft ring will not move upward with the upper cap 3. Continue to twist the upper cap 3 counterclockwise, so that the connection point between the upper cap 3 and the anti-theft ring breaks under the tension, and the neck of the upper cap 3 and the lower cap 2 separates. Consumers can drink the honey water from the neck.
