How plant hollow capsules work
The working principle of plant hollow capsules is based on its structural design, material properties and interaction with drugs.
1. Structural design principle
The snap-fit connection between the capsule body and the capsule cap has multiple limit slots on the outer surface of the capsule top opening, and a limit convex is set on the inner wall of the capsule cap opening, and the two are sealed by snapping.
A limit convex ring is installed on the outer side of the top of the capsule, and the bottom of the capsule cap is snapped with the limit convex ring, which cooperates with the sealing ring to improve the sealing and prevent drug leakage.
Functional structural design An annular groove is set on the outer surface of the capsule cap to increase the friction of the hand and facilitate picking and operation.
An identification ring is set on the inner wall of the capsule to assist in quantitative addition of drugs and improve the convenience of use.
2. Material properties and drug protection
Natural plant materials are mainly made of natural materials such as plant cellulose (such as cassava starch, bean protein) or starch, which are non-toxic, tasteless and biocompatible.
The material has high stability and is degradable, reducing pollution to the environment.
Drug protection mechanism The capsule shell dissolves in the stomach, releasing the drug, avoiding direct contact between the drug and gastric acid, and reducing irritation to the gastrointestinal mucosa.
The elasticity of the capsule shell can buffer the impact of the drug on the gastrointestinal tract, reduce the drug release rate, and prolong the drug effect.
3. Sealing and drug stability
The tight fit between the limiting card slot and the limiting protrusion of the sealing structure, combined with the extrusion of the sealing ring, forms a double sealing barrier to ensure that the drug does not leak during storage and transportation.
The inclined design of the sealing ring (inclination angle of 30 degrees) further enhances the sealing effect.
Drug stability guarantees that the sealing structure prevents the drug from getting damp, oxidized or reacting with other substances, ensuring the effectiveness and safety of the drug.
The low water content of the plant material (5%-8%) reduces the risk of chemical reactions with the drug.
4. Operation process
Drug filling Add the drug to the capsule, and observe the drug addition through the transparent capsule until the identification ring position is reached.
The design of the capsule facilitates precise control of the drug dosage.
Sealing packaging aligns the limiting protrusion of the capsule cap with the limiting card slot of the capsule body, pushes the capsule cap to engage with the capsule body, and squeezes the sealing ring to complete the sealing.
The annular groove design of the capsule cap is easy to operate and prevents slipping.
5. Advantages and Applications
Environmentally friendly and healthy plant hollow capsules avoid the use of animal-derived materials and meet the requirements of vegetarianism and religious diets.
The material is degradable and reduces environmental pollution.
Wide applicability It is suitable for the packaging of water-soluble drugs and solid granular drugs to meet the needs of different drug dosage forms.
It has broad application prospects in the fields of medicine, health care products, etc.
