Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of hollow capsules, and particularly relates to a quick-dissolving capsule. BACKGROUND

[0002] Medicines packed in capsules are generally powders or particles that are irritating to the esophagus and gastric mucosa, or have poor taste, are easily volatile, are easily decomposed by saliva in the oral cavity, and are easily inhaled into the trachea. These medicines are packed in capsules to protect the drug properties from being destroyed and to protect the digestive organs and respiratory tract. Removing the capsule shell can cause drug loss, waste of medicine, and reduction of drug efficacy. In medicine, a capsule is a capsule-shaped object made of special film-forming materials (such as gelatin, cellulose, polysaccharides, etc.) that is used to pack contents (such as powdery, liquid, and various types of medicines) or doses for easy swallowing. The dissolution of the capsule shell of traditional capsule products generally requires a relatively long period of time, and the medicine can act on the human body only after the capsule shell is dissolved. However, some medicines need to be quickly released to quickly take effect to meet the special use requirements in clinical practice. Therefore, it is necessary to conduct in-depth exploration and research on how to reduce the influence of the dissolution time of the capsule shell on the drug efficacy. In the prior art, quick-dissolving capsules are mostly provided with structures that are easy to dissolve at the ends or in the middle of the capsule body. After the capsule is taken, the medicine is released from the ends or the middle of the capsule, thereby accelerating the release of the medicine. However, the medicine in the capsule still needs to be gradually released from the inside of the capsule shell, and cannot be released at the same time. Therefore, it is necessary to design and develop a quick-dissolving capsule product that can more quickly release medicine. SUMMARY

[0003] Therefore, the present application aims to overcome the defects in the prior art and provides a quick-dissolving capsule.

[0004] To achieve the above-mentioned purposes, the technical scheme of the present application is as follows:

[0005] A quick-dissolving capsule comprises a middle shell body, the two ends of the middle shell body are respectively provided with connecting portions, a capsule body is inserted on each connecting portion, a limiting step is formed between the connecting portion and the main structure of the middle shell body, a middle shell body weak area is arranged on the main structure of the middle shell body in the circumferential direction, a ring-shaped weak area is arranged at the end of each capsule body away from the middle shell body, a plurality of capsule body weak areas are arranged from the end face of the capsule body close to the middle shell body to the ring-shaped weak area, and the diameter of the ring-shaped weak area is smaller than the outer diameter of the capsule body.

[0006] Further, the diameter of the ring-shaped weak area is 1 / 5-2 / 3 of the outer diameter of the capsule body.

[0007] Further, the inner diameter of the main body structure of the intermediate shell is greater than the inner diameter of the connecting portion.

[0008] Further, the wall thickness of the main body structure of the intermediate shell is less than the wall thickness of the connecting portion.

[0009] Further, at least two intermediate shell weak areas are provided on the intermediate shell along the circumferential direction of the intermediate shell.

[0010] Further, at least three capsule weak areas are provided on the end face of the capsule close to the side of the intermediate shell to the annular weak area.

[0011] Further, the capsule weak area is an indentation pressed along the surface of the capsule, and the wall thickness at the indentation is 1 / 4-1 / 3 of the wall thickness of the capsule.

[0012] Further, the intermediate shell weak area is an indentation pressed along the surface of the intermediate shell in the circumferential direction, and the wall thickness at the indentation is 1 / 4-1 / 3 of the wall thickness of the intermediate shell.

[0013] Compared with the prior art, the present application has the following advantages:

[0014] After the instant capsule is taken, the intermediate shell weak areas on the intermediate shell will dissolve first in the dissolving process, causing the intermediate shell to break off at the intermediate shell weak area position. In addition, the annular weak area and the capsule weak area will dissolve first before the capsule main body structure, causing the capsule to crack or fall off in pieces at multiple positions at the same time, so as to achieve the purpose of releasing the medicine in the capsule at the same time. The medicine is released faster, and the speed of exerting the drug efficacy is maximized. BRIEF DESCRIPTION OF DRAWINGS

For those skilled in the art, the specific meaning of the above terms in the present application can be understood through specific circumstances.

[0026] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0027] A kind of instant capsule, such as Figures 1 to 5 As shown, it includes intermediate shell 1, and the connecting part 2 is arranged on the two ends of the intermediate shell respectively, and the capsule 3 is inserted on each connecting part;Limiting step 5 is formed between the connecting part and the main body structure 4 of the intermediate shell, and the limiting step can ensure that the capsule and the intermediate shell are matched in place, and when the capsule is inserted into the connecting part, the end of the capsule abuts against the limiting step, which can ensure that the capsule is assembled in place.

[0028] The intermediate shell body structure is provided with an intermediate shell weak area 6 in the circumferential direction, and each capsule end away from the intermediate shell is provided with an annular weak area 7. Generally, the diameter of the annular weak area is 1 / 5-2 / 3 of the outer diameter of the capsule. The inner diameter of the main body structure of the intermediate shell is greater than the inner diameter of the connecting part. The wall thickness of the main body structure of the intermediate shell is less than the wall thickness of the connecting part.

[0029] The capsule body structure 11 is provided with a plurality of capsule weak areas 8 from the end face of the side close to the intermediate shell to the annular weak area, and the diameter of the annular weak area is less than the outer diameter of the capsule. The end face of the capsule close to the intermediate shell is provided with a plurality of deformation seams 9, and each capsule weak area is arranged corresponding to a deformation seam, and the end of the deformation seam away from the capsule weak area is open 10.

[0030] The deformation seam can produce a certain deformation during the insertion of the connecting part of the capsule and the intermediate shell, thereby ensuring the smooth assembly and fixation of the capsule and the connecting part. At the same time, the deformation seam is equivalent to a prefabricated cracking structure, which is very beneficial to quickly make the capsule main body structure decompose and crack at the capsule weak area during capsule dissolution, thereby quickly releasing the medicine in the capsule.

[0031] As an example, the intermediate shell is provided with at least two intermediate shell weak areas in the circumferential direction. The end face of the capsule close to the intermediate body is provided with at least three capsule weak areas from the annular weak area. The capsule weak area is an indentation pressed along the surface of the capsule, and the wall thickness at the indentation is 1 / 4-1 / 3 of the wall thickness of the capsule. The intermediate shell weak area is an indentation pressed along the surface of the intermediate shell in the circumferential direction, and the wall thickness at the indentation is 1 / 4-1 / 3 of the wall thickness of the intermediate shell.

[0032] After the instant capsule is taken, the intermediate shell weak area on the intermediate shell will dissolve before the main body structure of the intermediate shell, so that the intermediate shell is disconnected from the intermediate shell weak area. In addition, the annular weak area and the capsule weak area will dissolve before the capsule main body structure, so that the capsule is cracked or falls off in a piece shape at multiple positions at the same time, which can achieve the purpose of quickly releasing the medicine in the capsule. The medicine is released faster, and the speed of drug efficacy is maximized.

[0033] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
