Description

Technical Field

[0001] This utility model relates to a modular ampoule cap, specifically an ampoule cap that facilitates easy dispensing. Background Technology

[0002] In existing ampoule containers, a sealing and opening mechanism typically employs an inner stopper and an outer cap. A typical approach in existing technology involves an inner stopper at the ampoule opening, which, through a tight fit, prevents air and liquid leakage. An outer cap is then added to reinforce the seal and prevent the inner stopper from loosening or falling off during transport or storage. However, this structure has significant shortcomings in practical use.

[0003] First, each time the liquid in the ampoule needs to be used, the operator must first unscrew the outer cap and then remove the inner stopper, which is a relatively cumbersome process, especially in scenarios requiring quick use. Second, the traditional inner stopper structure does not have a liquid guiding function, leading to leakage when the user pours or applies the ampoule contents. This causes the liquid to easily spill out during use, wasting the medication and affecting the cleanliness of the operation. Utility Model Content

[0004] To address the aforementioned issues, this invention provides an ampoule cap that facilitates easy dispensing. By adding a positioning and sealing structure between the inner plug and the outer cap, the positioning and sealing needle can be directly inserted into and seal the liquid guiding hole after the outer cap is tightened. This ensures good sealing while enabling rapid opening and precise liquid guiding, avoiding the cumbersome operation and leakage defects of traditional structures.

[0005] This utility model is achieved through the following technical solution: an ampoule cap for convenient dispensing, comprising: An inner plug for sealing assembly with an outer container, the inner plug having a liquid guide hole; The outer cover has an internal thread on its inner ring for threaded assembly with an external container. A positioning and sealing structure is provided between the inner plug and the outer cover, and the liquid guiding hole of the inner plug is sealed by the positioning and sealing structure.

[0006] As a preferred technical solution, the positioning and sealing structure includes a positioning and sealing pin disposed on the outer cover. When the outer cover is installed on an external container, the positioning and sealing pin is inserted into the liquid guiding hole in a sealing manner.

[0007] As a preferred technical solution, a flared opening is provided at the top opening position of the liquid guiding hole.

[0008] As a preferred technical solution, a liquid guide tube is formed on the inner plug, the cross-section of the liquid guide tube is conical, and the liquid guide tube extends away from the inner plug.

[0009] As a preferred technical solution, the outer cover is provided with an anti-slip texture.

[0010] As a preferred technical solution, the outer wall of the inner plug is provided with a stepped assembly structure.

[0011] The beneficial effects of this invention are as follows: By setting a positioning and sealing structure between the inner stopper and the outer cap, this invention enables convenient opening and dispensing operations while maintaining good sealing of the ampoule. Compared to the traditional method of removing the inner stopper before pouring out the liquid, this invention allows the positioning and sealing pin to directly seal the liquid guide hole when the outer cap is tightened, avoiding the cumbersome steps of secondary disassembly and assembly, and improving efficiency. Because the top of the liquid guide hole is designed with a flared opening and forms a conical liquid guide tube on the inner stopper, it not only facilitates the smooth flow of liquid but also effectively concentrates and positions the liquid flow direction, reducing liquid spillage during application or dispensing.

[0014] All features disclosed in this specification, or steps in all methods or processes disclosed herein, may be combined in any way, except for mutually exclusive features and / or steps.

[0015] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0016] like Figures 1-3 As shown, this utility model provides an ampoule cap for convenient dispensing. In a specific embodiment, its structure and function are achieved in the following ways.

[0017] The ampoule cap includes an inner plug 2, which is used to tightly seal the opening of the outer container, thereby ensuring that the liquid inside the container does not come into contact with the outside air and preventing liquid evaporation or contamination. The inner plug 2 has a liquid guide hole 5 machined into its body structure, which serves as a liquid outlet channel, enabling smooth liquid discharge during use.

[0018] To further optimize the flow characteristics of the liquid, a funnel-shaped opening structure is set at the top opening position of the liquid guide hole 5. This funnel-shaped opening can guide the liquid flow, making the liquid flow more concentrated and reducing unnecessary waste and overflow caused by liquid deviation or diffusion.

[0019] On the inner plug 2, a liquid guide tube 4 is also formed. The liquid guide tube 4 extends downward from the liquid guide hole 5. Its cross-section is designed as a tapered structure and gradually tapers away from the inner plug 2. This conical design effectively reduces resistance during liquid discharge and provides a certain degree of positioning, allowing the liquid to form a more stable flow line as it passes through the liquid guide tube 4, thus preventing splashing caused by turbulence or deviation. The extension of the liquid guide tube 4 can be designed according to the depth of the container, ensuring smooth discharge of the liquid during pouring, further enhancing convenience and practicality.

[0020] As an important component of the ampoule cap, the outer cap 1 has an inner thread 3 structure that matches the bottle mouth of the container. By screwing, the outer cap 1 can be firmly installed on the bottle mouth of the outer container, achieving stable assembly and disassembly operations.

[0021] To improve the feel of the outer cover 1 during tightening and loosening, its outer surface is textured with an anti-slip texture. This texture provides additional friction during operation, preventing difficulties in tightening due to wet hands or insufficient force, thus ensuring safety and stability during use.

[0022] A positioning and sealing structure is provided between the inner plug 2 and the outer cover 1. The key component of this structure is the positioning and sealing pin 6 provided on the outer cover 1.

[0023] When the outer cap 1 is screwed on until fully assembled with the container, the positioning and sealing pin 6 can accurately insert into the liquid guide hole 5 of the inner plug 2, thereby achieving a sealing effect on the liquid guide hole 5. This structure avoids the problem of liquid leakage due to the open liquid guide hole 5 when not in use, and also simplifies the operation steps. When needed, the user only needs to unscrew the outer cap 1 to prepare for liquid dispensing, without having to separately remove the inner plug 2 as in traditional structures. This positioning and sealing structure improves the sealing effect and also enhances the efficiency of use.

[0024] In addition, the outer wall of the inner plug 2 is designed with a stepped assembly structure, which achieves a tighter fit with the bottle neck through multiple stepped transitions.

[0025] The stepped assembly not only enhances sealing performance but also serves to limit movement and prevent loosening, ensuring that the inner plug 2 is less prone to displacement or loosening during long-term storage or frequent use, thereby further improving the overall sealing stability of the container. This stepped structural design also helps to distribute stress during assembly to some extent, reducing the risk of seal failure caused by concentrated local stress.

[0026] The operation of this ampoule cap is very simple. When it is necessary to take out the liquid from the container, the user only needs to unscrew the outer cap 1, and the positioning sealing needle 6 will then retract from the liquid guide hole 5. The liquid guide hole 5 will immediately be in the open state, and the liquid can flow out smoothly through the flared mouth and the liquid guide tube 4.

[0027] Due to the guiding effect of the liquid guide hole 5 and the liquid guide tube 4, the liquid can be accurately concentrated and flowed to the target position, avoiding spillage caused by unstable liquid flow. After use, the user tightens the outer cap 1 again, and the positioning sealing pin 6 is reinserted into the liquid guide hole 5 to form a seal, which not only ensures the airtightness of the container, but also prevents liquid residue from leaking out of the bottle mouth. The operation process is simple and smooth.

[0028] This utility model, through the rational design of the inner plug 2, outer cap 1 and positioning sealing structure, combined with the detailed optimization of the flared mouth, conical liquid guide tube 4, anti-slip texture and stepped assembly structure, not only achieves a good sealing effect for ampoules, but also greatly improves the convenience and accuracy of liquid dispensing, and solves the problems of cumbersome operation, easy liquid overflow and insufficient sealing in the prior art.

[0029] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
