Description

Ready-to-use bottle caps Technical Field

[0001] The present invention relates to the technical field of bottle caps, and in particular to a ready-to-use bottle cap. Background Art

[0002] Traditional packaged beverages (such as bottled tea drinks) are sold after mixing the solute with water. In order to extend the shelf life of the beverage, preservatives and stabilizers are added, which not only affects the taste but also causes harm to the human body. Therefore, ready-to-use bottle caps came into being. The solute is sealed and stored in the bottle cap, which can effectively and stably preserve the activity of various nutrients. When the beverage needs to be consumed, the solute in the bottle cap is released into the water, which not only can obtain a longer shelf life, but also a fresh taste without the addition of any artificial preservatives, which is more in line with the needs of healthy drinks.

[0003] Existing instant bottle caps typically use a weak layer structure design. When drinking, the weak layer is punctured or opened, causing the solute in the storage chamber to flow out and mix with the water in the bottle. This type of design has the following problems:

[0004] 1. The difficulty in processing the sealing film or weak layer leads to high processing costs. For example, the bonding processing space of the sealing film structure is limited, and the injection molding process of the weak layer structure is difficult, inefficient, and has a high production defect rate.

[0005] 2. The sealing film or weak layer is relatively thin, resulting in insufficient stability and sealing. First, the sealing film or weak layer is easily damaged during storage or transportation, thus affecting the quality of the encapsulated solute. Second, even if the weak layer is intact, its sealing performance as a barrier to oxygen and moisture is insufficient.

[0006] Summary of the Invention

[0033] Example 1

[0034] 1-4 , the instant bottle cap of this embodiment includes a cap body 1A and a sealing plug 2A. The cap body 1A and the sealing plug 2A form a sealed storage cavity 4A for storing solutes.

[0035] Among them, the cover body 1A includes an integrally formed pressing part 11A, an elastic part 12A, a protective part 13A, a top column 14A and a cover tube 15A. The edge of the pressing part 11A extends outward to form the elastic part 12A, and the edge of the elastic part 12A extends in the direction away from the storage chamber 4A to form the protective part 13A. The protective part 13A is an annular cylindrical structure, and the protective part 13A is used to accommodate the pressing part 11A and the elastic part 12A; the upper end of the top column 14A is vertically integrated with the bottom of the pressing part 11A, and the lower end is clamped with the sealing plug 2A; the top of the cover tube 15A is integrally connected with the edge of the elastic part 12A, the axial direction of the cover tube 15A is opposite to the extension direction of the protective part 13A, the bottom of the cover tube 15A is open, and the cover tube 15A is slidingly and sealingly connected with the sealing plug 2A to form the storage chamber 4A. Specifically, the sealing plug 2A, the pressing portion 11A, the elastic portion 12A and the cover tube 15A form a sealed material storage chamber 4A.

[0036] Under the action of external force, the pressing part 11A can drive the elastic part 12A to deform and move into the storage cavity 4A. The top column 14A simultaneously pushes the sealing plug 2A downward, so that the sealing plug 2A is disconnected from the bottom inner wall of the cover tube 15A, thereby opening the storage cavity 4A.

[0037] In this embodiment, the elastic portion 12A is made of a flexible material. In the absence of external force, the elastic portion 12A has an arc-shaped convex structure due to its own elastic force, and the arc-shaped convex surface faces upward. When subjected to downward pressure from an external force, the elastic portion 12A can be concave downward.

[0038] The instant bottle cap proposed in this embodiment only requires two injection-molded parts, namely the cap body 1A and the sealing plug 2A, which can save one part, making the structure of the instant bottle cap simpler and reducing production costs. In addition, only the connection between the sealing plug 2A and the cap tube 15A needs to be sealed, which reduces the difficulty of sealing.

[0039] In addition, the sealing plug structure adopted has a small contact area between the plug ring of the sealing plug and the bottom of the inner wall of the cover tube, so the friction is small. When using the product, the resistance of manually applying pressure to the pressing part of the upper cover to open the storage chamber is small, which is more labor-saving and smooth.

[0040] In this embodiment, the height of the protective portion 13A is greater than the height of the pressing portion 11A. The protective portion 13A, the pressing portion 11A, and the elastic portion 12A can be injection molded in one step during production, eliminating the need for additional protective components to protect the pressing portion 11A. The height of the protective portion 13A is greater than the height of the pressing portion 11A to prevent accidental contact of the pressing portion 11A with external forces when not in use, thereby simplifying the structure of the ready-to-dispense bottle cap, saving components, and reducing the production cost of the ready-to-dispense bottle cap.

[0041] In this embodiment, the sealing plug 2A includes a plug ring 21A, a plug surface 22A, a plug bottom 23A, and a snap-in hole 24A. The sealing plug 2A as a whole is a cone-like structure. The part that is directly sealed and connected to the bottom end of the inner wall of the cover tube 15A is the plug ring 21A, and the end facing the storage chamber 4A is the plug surface 22A, which is a cone with an arc-shaped slope. A snap-in hole 24A is provided at the top of the cone, and the top column 14A of the cover body 1A is plugged into the snap-in hole 24A. The plug bottom 23A is a lightweight structure with multiple nested circular rings of different sizes, and the bottoms of the multiple rings are flush. After the sealing plug 2A and the cover tube 15A are sealed and snap-in into place, the bottoms of the two are flush.

[0042] In this embodiment, the outer wall of the plug ring 23A is provided with an integrally formed annular convex sealing line 211A. The diameter of the annular convex sealing line 211A is slightly larger than the inner diameter of the cover tube 15A. The elasticity of the injection molded part forms an interference fit between the sealing plug 2A and the cover tube 15A to achieve a better sealing effect.

[0043] In this embodiment, the inner wall of the engaging hole 24A is provided with an annular groove 241A, and the outer wall of the lower portion of the top post 14A is provided with an annular protrusion 141A that mates with the annular groove 241A. The engagement of the annular protrusion 141A with the annular groove 241A provides a more secure and stable insertion, thereby preventing the sealing plug 2A from falling out after the storage chamber 4A is opened. In other embodiments, the concave-convex matching structure of the annular groove 241A and the annular protrusion 141A can also be reversed, that is, the inner wall of the engaging hole 24A is provided with an annular protrusion, and the outer wall of the lower portion of the top post 14A is provided with an annular groove.

[0044] In this embodiment, the cap 1A further includes a cap body 16A, which is integrally disposed on the periphery of the cap tube 15A. A connecting groove is formed between the cap body 16A and the cap tube 15A. The inner wall of the cap body 16A is provided with internal threads 161A for connecting with the external threads of the bottle mouth. The bottle mouth is inserted into the connecting groove and screwed together to achieve connection between the bottle cap and the bottle mouth.

[0045] In the above embodiment, the sealing plug 2A and the cover tube 15A are connected in a sliding sealing manner. Although the sealing plug 2A and the cover tube 15A are interference fit, which can achieve a better sealing effect, in order to further enhance the sealing performance, a sealing film 3A is also provided in this embodiment. The lower surface of the sealing plug 2A flush with the cover tube 15A can be welded to the sealing film 3A by ultrasonic or hot melt process to cover the gap between the structural parts, so as to achieve a seamless and better sealing effect.

[0046] The working principle of the instant bottle cap of Example 1 is: the one-piece molded cap body 1A is inverted so that the opening at the bottom of the cap tube 15A faces upward, and an appropriate amount of solute is injected into the storage cavity 4A through this opening, and then the plug surface 22A of the sealing plug 2A is assembled to the bottom of the cap tube 15A facing the storage cavity 4A, so that the top column 14A of the cap body 1A is inserted into the snap-fit ​​hole 24A of the sealing plug 2A to form a firm snap-fit, and at the same time, the plug ring 21A of the sealing plug 2A is sealed and connected to the inner wall of the bottom of the cap tube 15A, thereby sealing the solute in the storage cavity 4A.

[0047] In order to further enhance the sealing performance, the lower surface of the sealing plug 2A flush with the cover tube 15A can be welded with a sealing film 3A using ultrasonic or hot melt technology to cover the gap between the structural parts to achieve a seamless and better sealing effect.

[0048] After the instant bottle cap is filled with solute and assembled and sealed, the bottle is purified and filled with water, and the instant bottle cap is assembled on the bottle using an automatic screw-on capping process. The instant bottle cap and the bottle can be tightened through the internal thread 161A and the external thread to form a sealed fit. The bottle using the instant bottle cap is then completely produced, processed and assembled.

[0049] During use, press the pressing portion 11A of the cover body 1A downward with your fingers, push the top column 14A to drive the sealing plug 2A to move downward, so that the sealing plug 2A is separated from the sealing shield of the inner wall of the cover tube 15A, and at the same time, the sealing film 3A is separated from the bottom of the cover tube 15A but is still adhered to the plug bottom 23A of the sealing plug 2A and will not fall into the bottle, thereby opening the storage cavity 4A. The solute pre-filled in the storage cavity 4A falls out from the gap between the sealing plug 2A and the bottom of the cover tube 15A under the action of gravity, falls into the bottle and mixes and dissolves with the water in the bottle. After shaking to mix evenly or letting it stand for a period of time to fully dissolve, it can be drunk.

[0050] In order to fully utilize the diameter of the cap body 1A as the maximum diameter of the storage cavity 3A, thereby expanding the capacity of the storage cavity 3A of the instant bottle cap, and at the same time to prevent the cap tube 15A from extending downward too much, thereby reducing the space occupied by the bottle interior and increasing the water storage capacity of the bottle, the cap body 1A can be divided into two parts: an upper cover and a lower cover, thereby obtaining the following embodiments 2 and 3.

[0051] Example 2

[0052] 5 to 10 , the instant bottle cap of this embodiment includes an upper cover 1B, a lower cover 2B, and a sealing plug 3B. The upper cover 1B, the lower cover 2B, and the sealing plug 3B enclose and form a sealed material storage chamber 5B.

[0053] The upper cover 1B includes an integrally formed pressing portion 11B, a curved flexible portion 12B, an annular protective portion 13B, a top column 14B, and an upper cover tube 15B. The protective portion 13B protrudes upward to form a protective area for accommodating the pressing portion 11B and the curved flexible portion 12B. The pressing portion 11B, the curved flexible portion 12B, and the annular protective portion 13B are integrally connected, and the height of the annular protective portion 13B is greater than the height of the pressing portion 11B to prevent accidental contact of the pressing portion 11B by external force when not in use. The sealing plug 3B is detachably and hermetically connected to the bottom of the lower cover 2B to seal the storage chamber 5B. The top column 14B is integrally arranged below the pressing portion 11B, and the upper cover tube 15B is integrally arranged on the bottom surface of the protective portion 13B. The upper cover 1B has a structure with a closed top and an open lower end of the upper cover tube 15B.

[0054] The lower cover 2B includes a lower cover body 21B and a lower cover tube 22B. The lower cover 2B is a cylindrical structure with upper and lower openings, and the lower cover body 21B is integrally sleeved on the outside of the lower cover tube 22B. This embodiment shows a sealing and fixed connection method between the upper cover 1B and the lower cover 2B. Specifically, the upper cover tube 15B and the lower cover body 21B are sealed and fixedly connected by a snap-fit ​​method.

[0055] Specifically, the lower end of the upper cover tube 15B is provided with an upper clamping portion 151B in a double-ring shape, and a clamping gap is formed between the double rings of the upper clamping portion 151B. The upper end of the lower cover body 21B is provided with a lower clamping portion 211B in a double-ring shape, and a clamping gap is formed between the double rings of the lower clamping portion 211B. The upper clamping portion 151B and the lower clamping portion 211B are sealed clamping structures that match each other. The double ring structures of each other are alternately inserted into the clamping gaps of each other, and the upper clamping portion 151B and the lower clamping portion 211B are correspondingly provided with annular protrusions T1 and annular grooves C1 to cooperate in clamping, so as to achieve a more sealed and firmer clamping effect.

[0056] In this embodiment, the sealing plug 3B is slidingly and sealingly connected to the bottom of the lower cover tube 22B to seal the storage chamber 5B; the upper end of the top column 14B is vertically and integrally connected to the bottom of the pressing portion 11B of the upper cover 1B, and its lower end is fixedly engaged with the sealing plug 3B.

[0057] The sealing plug 3B in this embodiment includes a plug ring 31B, a plug surface 32B, a plug bottom 33B and a snap-in hole 34B. The connection relationship of the various components of the sealing plug 3B in this embodiment is consistent with the connection relationship of the various components in the sealing plug 2A involved in Example 1. At the same time, the connection relationship between the sealing plug 3B and the lower cover tube 22B is consistent with the connection relationship between the sealing plug 2A and the cover tube 15A, which will not be repeated here. Accordingly, the inner wall of the snap-in hole 34B is provided with an annular groove 341B, and the outer wall of the top column 14B is correspondingly provided with an annular protrusion 141B that cooperates with the annular groove 341B to achieve a more secure and stable plug-in effect so that the sealing plug 3B is not easy to fall off after the storage chamber 5B is opened. In some other embodiments, the concave-convex matching structure of the annular groove 341B and the annular protrusion 141B can also be reversed, that is, the inner wall of the snap-in hole 34B is provided with an annular protrusion, and the outer wall of the lower part of the top column 14B is provided with an annular groove.

[0058] In addition, in order to improve the sealing performance between the sealing plug 3B and the lower cover tube 22B, this embodiment also provides an integrally formed annular convex sealing line 311B on the outer wall of the plug ring 31B. The diameter of the annular convex sealing line 311B is slightly larger than the inner diameter of the lower cover tube 22B, so as to form an interference fit between the sealing plug 3B and the lower cover tube 22B through the elasticity of the injection molded part, so as to achieve a better sealing effect.

[0059] In this embodiment, the lower cover body 21B is integrally sleeved onto the outer side of the lower cover tube 22B. A connecting groove is formed between the lower cover body 21B and the lower cover tube 22B, for inserting the bottle mouth into the connecting groove and securely connecting to the cover body. Furthermore, the inner wall of the lower cover body 21B is provided with internal threads 212B, facilitating insertion of the bottle mouth into the connecting groove. The external threads of the bottle mouth and the internal threads 21B of the lower cover body 21B are threadedly connected.

[0060] It should be noted that, based on Example 2, as an embodiment, referring to FIG9 , the lower cover tube 22B is a straight cylinder, with its inner diameter remaining constant along its axial direction, and the inner wall of the bottom of the lower cover tube 22B is sealed to the sealing plug 3B. The straight cylinder design allows the discharge port formed after the sealing plug 3B is opened to be larger, which is suitable for filling large amounts of solute particles with poor fluidity or viscous liquids such as meal replacement powder, milk tea ingredients, honey, etc.

[0061] As another embodiment, as shown in FIG10 , the lower cover tube 22B can also be configured as a funnel-shaped device, with its cross-sectional inner diameter gradually decreasing, and the inner wall of the bottom of the lower cover tube 22B is sealed to the sealing plug 3B. The funnel-shaped design makes the discharge port formed after the sealing plug 3B is opened more aesthetically pleasing, and is suitable for small-volume, high-flowability powdered solute particles or concentrated liquids, such as freeze-dried tea powder, freeze-dried coffee powder, tea concentrate, and coffee concentrate.

[0062] In the second embodiment, in order to further enhance the sealing performance, the lower surface of the sealing plug 3B flush with the lower cover tube 22B can be welded with a sealing film 4B by ultrasonic or hot-melt process to cover the gaps between the structural parts and achieve seamless and better sealing effect.

[0063] The working principle of the instant bottle cap of Example 2 is as follows: first, the upper cover 1B and the lower cover 2B are assembled together, and the two are clamped together by their respective upper clamping parts 151B and lower clamping parts 211B to form a sealed connection. Then, an appropriate amount of solute is injected into the storage cavity 5B, and the sealing plug 3B is sealed to the bottom inner wall of the lower cover tube 22B, thereby sealing the solute in the storage cavity 5B, and the assembly of the instant bottle cap is completed. The operation method of installing the instant bottle cap of Example 2 on the bottle and opening the storage cavity 5B is the same as the operation method of Example 1, and will not be repeated here.

[0064] In the second embodiment, although the upper cover and the lower cover are fixedly connected by a double clamping method, although the sealing requirement can be achieved to a certain extent, it cannot meet the complete sealing requirement. For example, if mechanical vibration occurs between the upper cover and the lower cover, the sealing leakage at the connection may occur. In response to the above problems, ultrasonic welding can achieve better sealing. However, in the above second embodiment, the connection between the upper cover and the lower cover is located in the middle of the entire bottle cap. The sealing connection between the upper cover and the lower cover is achieved by ultrasonic welding. The welding point is far away from the welding head, which is not convenient for near-field welding. The welding efficiency and quality are low, resulting in unstable overall sealing performance of the instant bottle cap. Therefore, the present invention proposes a new method for connecting the upper cover and the lower cover.

[0065] Example 3

[0066] 11 to 15 , the instant bottle cap of this embodiment includes an upper cover 1C, a lower cover 2C, and a sealing plug 3C. The upper cover 1C, the lower cover 2C, and the sealing plug 3C together form a sealed material storage chamber 5C.

[0067] The upper cover 1C includes an integrally formed pressing portion 11C, an elastic portion 12C, a protective portion 13C, a top post 14C, and an upper cover tube 15C. The protective portion 13C protrudes upward to form a protective area for accommodating the pressing portion 11C and the elastic portion 12C. The pressing portion 11C is fixedly connected to the elastic portion 12C and the protective portion 13C, and the height of the protective portion 13C is greater than the height of the pressing portion 11C to prevent external forces from accidentally touching the pressing portion 11C when not in use. The top post 14C is integrally arranged below the pressing portion 11C, and the upper cover tube 15C is fixedly arranged on the bottom surface of the protective portion 13C. The upper cover 1C has a structure with a closed top and an open lower end of the upper cover tube 15C.

[0068] The lower cover 2C includes a lower cover body 21C and a lower cover tube 22C. The lower cover 2C is a cylindrical structure with upper and lower openings, and the lower cover body 21C is integrally sleeved on the outside of the lower cover tube 22C. In this embodiment, the upper cover 1C and the lower cover 2C need to be sealed and fixedly connected, so that the upper cover 1C, the lower cover 2C and the sealing plug 3C enclose and form a storage chamber 5C.

[0069] This embodiment utilizes ultrasonic welding to connect the upper cover 1C and lower cover 2C. Specifically, the top of the lower cover body 21C is extended upward to form a cylindrical structure, which increases the volume of the storage chamber 5C. The inner wall of the lower cover body 21C is connected to the outer wall of the upper cover tube 22C, and the top surface of the lower cover body 21C is ultrasonically welded to the bottom surface of the protective portion 13C.

[0070] By adopting the above technical solution, the upper cover tube 22C is inserted into the lower cover body 21C, so that the outer wall of the upper cover tube 22C and the inner wall of the lower cover body 21C are abutted against each other, and radial positioning between the upper cover 1C and the lower cover 2C can be achieved. By applying ultrasonic welding on the top surface of the protective part 13C, the welding position is located at the top of the entire bottle cap, which can reduce the inclination angle of the welding head. At the same time, the distance between the ultrasonic welding head and the welding position is reduced, which can achieve near-field welding, improve welding efficiency and quality, and thus improve the overall sealing performance of the ready-to-use bottle cap.

[0071] In some preferred embodiments, a fuse 131C is integrally formed at the bottom surface of the protective portion 13C where it abuts the lower cover 21C. This fuse 131C has a triangular longitudinal cross-section and is used for ultrasonic welding to achieve a better weld quality. During ultrasonic welding, fuse 131C focuses vibration energy at the tip of the triangle. The accumulated heat then forms a uniform plastic melt flow across the entire weld interface, increasing weld strength, reducing cold welds, flash, and vibration amplitude, enhancing the weld quality, and even reducing processing time.

[0072] The sealing plug 3C in this embodiment includes a plug ring 31C, a plug surface 32C, a plug bottom 33C and a snap-in hole 34C. The connection relationship of the various components of the sealing plug 3C in this embodiment is consistent with the connection relationship of the various components of the sealing plug 3B involved in Example 2. Accordingly, the connection relationship between the sealing plug 3C and the lower cover tube 22C is consistent with the connection relationship between the sealing plug 3B and the lower cover tube 22B in Example 2, which will not be repeated here. Accordingly, the inner wall of the snap-in hole 34C is provided with an annular protrusion 341C, and the outer wall of the top column 14C is correspondingly provided with an annular groove 141C that cooperates with the annular protrusion 341C, so as to achieve a more secure and stable plug-in effect so that the sealing plug 3C is not easy to fall off after the storage chamber 5C is opened. In some other embodiments, the concave-convex matching structure of the annular protrusion 341C and the annular groove 141C can also be reversed, that is, the inner wall of the snap-in hole 34C is provided with an annular groove, and the outer wall of the lower part of the top column 14C is provided with an annular protrusion.

[0073] In addition, in order to improve the sealing performance between the sealing plug 3C and the lower cover tube 22C, this embodiment also provides an integrally formed annular convex sealing line 311C on the outer wall of the plug ring 31C. The diameter of the annular convex sealing line 311C is slightly larger than the inner diameter of the lower cover tube 22C, so as to form an interference fit between the sealing plug 3C and the lower cover tube 22C through the elasticity of the injection molded part, so as to achieve a better sealing effect.

[0074] In this embodiment, the lower surface of the sealing plug 3C flush with the lower cover tube 22C can be welded with a sealing film 4C using ultrasonic or hot melt technology to cover the gap between the structural parts to achieve a seamless and better sealing effect.
