Description

Technical Field

[0001] This utility model relates to the field of sealing cap technology, and in particular to a hybrid sealing cap with a spiral-driven dual compartment. Background Technology

[0002] Screw-lock caps are a very common and practical type of bottle cap. They achieve a seal on a container by interlocking and rotating the internal and external threads.

[0003] Some solvent systems (solid / liquid or liquid / liquid) have chemical compatibility issues. Long-term storage can easily lead to interactions between components, resulting in decreased stability of the contents. For such solvent systems, a fresh-for-use preparation method is usually required, which necessitates that each component solvent be stored independently and strictly sealed. In practice, repeated opening and closing of containers for multi-component transfer and mixing not only increases the risk of material exposure to air but also significantly reduces operational efficiency due to frequent opening and closing operations, creating a conflict between storage safety and operational convenience. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art where repeated opening and closing of containers is required for multi-component transfer and mixing in actual operation. This not only increases the risk of materials coming into contact with air, but also significantly reduces work efficiency due to frequent opening and closing operations, creating a contradiction between storage safety and operational convenience.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a hybrid sealing cover with a spiral-driven dual-compartment design, comprising: Bottle cap and connector; The bottle cap has two compartments inside, and each compartment is separated by a sealing film fixedly connected to its end. The bottle cap and the connector are slidably fitted together and sealed by a threaded connection; A puncture structure is provided inside the connector and is used in conjunction with the bottle cap.

[0006] In a preferred embodiment, the bottle cap includes an inner slide cylinder, a partition is provided inside the inner slide cylinder to form a double compartment, a cap is fixedly connected to the end of the inner slide cylinder, and a first internal thread is provided inside the cap to facilitate threaded connection with the connecting body.

[0007] In a preferred embodiment, the connector includes an outer cylinder with an external thread at one end near the bottle cap. An installation cap is fixedly connected to the middle of the outer cylinder, and the installation cap has a second internal thread that can cooperate with the external bottle body to install the connector.

[0008] In a preferred embodiment, the piercing structure includes two symmetrically distributed spikes. The spikes are fixedly connected to the end of the outer cylinder away from the external thread. The spikes are triangular pyramidal in shape. The sharp tips of the spikes can cut open the sealing film during the reverse rotation of the bottle cap, thereby achieving the function of solid / liquid mixing in the two compartments.

[0009] In a preferred embodiment, the outer periphery of the cap is provided with evenly distributed grooves to increase the contact friction between the cap and the user's hand, making it easier for the user to rotate the cap.

[0010] In a preferred embodiment, a sealing strip is provided between the bottle cap and the connector. The sealing strip can prevent accidental opening by misoperation. The cap can only be rotated after the sealing strip is broken, thus preventing damage to the contents caused by misoperation.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention features a dual-compartment design, physically separated by a sealing membrane. During use, rotating the cap in the opposite direction lowers the dual compartments, and a spiked cone pierces the sealing membrane, allowing for mixing of the components during opening. Independent storage in the dual compartments prevents the contents from affecting each other, thus extending the shelf life. This invention is simple, quick, and highly efficient in mixing.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 This utility model provides a technical solution: a hybrid sealing cover with a spiral-driven dual compartment, comprising: Bottle cap 1 and connector 2; The bottle cap 1 has two compartments inside, and each compartment is separated by a sealing film 5 fixedly connected to its end; The bottle cap 1 and the connecting body 2 are slidably fitted together and sealed by a threaded connection; The puncture structure is located inside the connector 2 and is used in conjunction with the bottle cap 1. It features a dual-compartment design, physically separated by a sealing membrane. During use, simply rotate the cap in the opposite direction to lower the dual compartments. A spiked nozzle is used to puncture the sealing membrane, allowing the ingredients to mix during opening. The independent storage of the dual compartments prevents the contents from affecting each other, thereby extending the shelf life of the contents. This application is simple and quick to operate, with high mixing efficiency.

[0016] like Figure 1-4 As shown, the bottle cap 1 includes an inner slide cylinder 102, and a partition is provided inside the inner slide cylinder 102 to form a double compartment. A cap 101 is fixedly connected to the end of the inner slide cylinder 102. The cap 101 is provided with a first internal thread 103 inside. The first internal thread 103 facilitates threaded connection with the connecting body 2.

[0017] like Figure 1-4 As shown, the connecting body 2 includes an outer cylinder 201. An external thread 202 is provided at one end of the outer cylinder 201 near the bottle cap 1. An installation cap 203 is fixedly connected to the middle of the outer cylinder 201. A second internal thread 204 is provided inside the installation cap 203. The second internal thread 204 can cooperate with an external container with threads to install the connecting body 2. The external thread 201 is threadedly connected to the first internal thread 103.

[0018] like Figure 1-4 As shown, the puncture structure includes two symmetrically distributed spikes 3. The spikes 3 are fixedly connected to the end of the outer cylinder 201 away from the external thread 202. The spikes 3 are triangular pyramids. The sharp spikes at the top of the spikes 3 can cut open the sealing film 5 during the reverse rotation of the bottle cap 1, so as to realize the function of solid / liquid mixing in the two compartments.

[0019] like Figure 1-4As shown, the cap 101 has evenly distributed grooves on its outer periphery to increase the contact friction between the cap and the user's hand, making it easier for the user to rotate the cap 101.

[0020] like Figure 1-4 As shown, a sealing strip 4 is provided between the bottle cap 1 and the connecting body 2. The sealing strip 4 can prevent accidental opening by misoperation. The cap can only be rotated after the sealing strip is broken to prevent damage to the contents caused by misoperation.

[0021] Working principle: During use, the connector 2 needs to be installed on the mixing container bottle. Remove the sealing strip 4 so that the bottle cap 1 can be rotated. By rotating the bottle cap 1 in the opposite direction, the inner slide cylinder 102 can be rotated downward. During this process, the spike 3 can cut open the sealing film 5 to realize the function of solid / liquid mixing in the two chambers. After mixing, the bottle cap 1 can be unscrewed to obtain the contents of the mixture.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms installation, setting, connection, etc., should be interpreted broadly. For example, connection can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
