Description

Technical Field

[0001] This utility model belongs to the field of hollow capsules, and in particular relates to a plant hollow capsule. Background Technology

[0002] Plant-based empty capsules consist of a cap and a body, made from pharmaceutical-grade hydroxypropyl methylcellulose; they are primarily used to contain solid and liquid medications, such as homemade powders, health supplements, and pharmaceuticals. This solves the problem of unpleasant taste and difficulty in swallowing, truly making good medicine palatable.

[0003] Currently, in order to prevent the leakage of drugs from the plant-based hollow capsules, the gap between the capsule cap and the capsule shell is minimized. This makes the assembly of the capsule cap and capsule shell difficult. In addition, the existence of the assembly gap means that the sealing effect of powdered drugs cannot be optimal, meaning that powdered drugs may leak from inside the capsule. Utility Model Content

[0004] In view of this, the present invention aims to provide a plant-based hollow capsule to improve the sealing effect of the contained medicine.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A plant-based hollow capsule includes a capsule shell and a capsule cap, both of which are cylindrical structures. The capsule shell is closed at the bottom and open at the top, while the capsule cap is closed at the top and open at the bottom. The capsule cap is fitted onto the opening of the capsule shell.

[0007] The outer side of the capsule shell is provided with a first conical surface, and the inner side of the capsule cap is provided with a second conical surface corresponding to the first conical surface. The second conical surface and the first conical surface are assembled to form a conical sealing structure.

[0008] A connecting and fixing structure is provided between the capsule cap and the capsule shell.

[0009] Furthermore, the connection and fixing structure includes an external thread provided on the outer side of the capsule shell and a corresponding internal thread provided on the inner side of the capsule cap, wherein the external thread and the internal thread are threadedly connected.

[0010] Furthermore, the first conical surface is positioned close to the capsule shell opening, and the bottom diameter of the first conical surface is not greater than the outer diameter of the capsule shell; the external thread is positioned below the first conical surface.

[0011] The internal thread is positioned close to the capsule cap opening, and the second conical surface is positioned above the internal thread.

[0012] Furthermore, the angle of the apex corresponding to the first conical surface is 8-12°.

[0013] Furthermore, the inner surfaces of the capsule shell and capsule cap are respectively provided with vertically protruding reinforcing ribs.

[0014] Compared with the prior art, the plant-based hollow capsule of this utility model has the following advantages:

[0015] In this invention, the first conical surface of the capsule shell and the second conical surface of the capsule cap of the plant hollow capsule are assembled to form a conical sealing structure, which effectively seals the contained medicine and prevents drug leakage. The capsule shell and the capsule cap are fixed together by a connecting and fixing structure to prevent the capsule shell and capsule cap from loosening, thus effectively improving the practicality of the plant hollow capsule.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] like Figure 1 As shown, a plant hollow capsule includes a capsule shell 1 and a capsule cap 2. Both the capsule shell 1 and the capsule cap 2 are cylindrical structures. The capsule shell 1 is closed at the bottom and open at the top, while the capsule cap 2 is closed at the top and open at the bottom. The capsule cap 2 is fitted onto the opening of the capsule shell 1.

[0025] Capsule shell 1 structure as follows Figure 2As shown, a first conical surface 12 is provided on the outer surface of the capsule shell 1 close to the opening. The bottom end of the first conical surface 12 is the larger end, and the top end is the smaller end, and the diameter of the bottom end of the first conical surface 12 is not greater than the outer diameter of the capsule shell 1. In this invention, the angle of the apex angle corresponding to the first conical surface 12 is 8-12°. An external thread 11 is provided on the outer surface of the capsule shell 1 below and adjacent to the first conical surface 12.

[0026] Capsule Cap 2 Structure as follows Figure 3 As shown, an internal thread 21 is provided on the inner side of the corresponding external thread 11 at the position close to the opening. A second conical surface 22 is provided on the inner side of the internal thread 21 and close to the internal thread 21. The second conical surface 22 and the first conical surface 12 are provided accordingly.

[0027] When capsule cap 2 and capsule shell 1 are assembled, the second conical surface 22 and the first conical surface 12 are assembled to form a conical sealing structure, and the internal thread 21 and the external thread 11 are threaded together to form a connection and fixing structure, thereby fixing capsule cap 2 and capsule shell 1 together.

[0028] In this invention, the structure after the capsule cap 2 and capsule shell 1 are assembled is as follows: Figure 4 As shown, the capsule cap 2 and capsule shell 1 are fixed together by the connecting and fixing structure to prevent the capsule cap 2 and capsule shell 1 from loosening. At the same time, the conical sealing structure formed between the second conical surface 22 and the first conical surface 12 seals the drug, effectively improving the sealing effect of the plant hollow capsule, preventing drug leakage, and ensuring the practicality of the capsule.

[0029] In this invention, the inner surfaces of the capsule shell 1 and the capsule cap 2 are integrally formed with vertically protruding reinforcing ribs 3. This structure can improve the strength of the plant hollow capsule and prevent the capsule from easily deforming.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
