Description

[Technical Field]

[0001] This utility model relates to the technical field of hollow capsules, and in particular to the technical field of gelatin hollow capsules with stable sealing effect. [Background Technology]

[0002] The existing hollow capsule structure mainly consists of two parts: the capsule body and the capsule cap. The capsule body and the capsule cap are U-shaped, and the inner diameter of the opening side of the capsule cap matches the outer diameter of the capsule body, so that the opening side of the capsule body is inserted into the opening side of the capsule cap to form an internal cavity for containing drug particles. In practical applications, the capsule cap and the capsule body are often not tightly connected or the connection is detached, which leads to leakage of drug particles inside the hollow capsule and affects the efficacy and quality of the capsule. [Utility Model Content]

[0003] The purpose of this invention is to solve the problems in the prior art and propose a gelatin hollow capsule with stable sealing effect. It can limit the inner end by using the anti-retraction teeth at the lower part of the inner limiting groove in conjunction with the anti-retraction groove at the bottom of the capsule body. At the same time, it can achieve sealing and limiting by using the limiting protrusion on the outer side of the capsule body in conjunction with the limiting ring groove on the inner side of the capsule cap. The connection part is not easy to loosen or detach, and the sealing effect is stable.

[0004] To achieve the above objectives, this utility model proposes a gelatin hollow capsule with stable sealing effect, comprising a capsule body, a limiting protrusion ring, a guide cone opening, an anti-retraction groove, a capsule cap, a limiting ring groove, an inner limiting groove, and anti-retraction teeth. The lower outer side of the capsule body is provided with a limiting protrusion ring, the bottom end of the capsule body is provided with a guide cone opening, the upper part of the guide cone opening is provided with an anti-retraction groove, the lower part of the capsule body is fitted with a capsule cap, the inner side of the capsule cap is provided with a limiting ring groove corresponding to the limiting protrusion ring, the upper part of the inner side of the capsule cap is provided with an inner limiting groove, and the inner side of the inner limiting groove is provided with anti-retraction teeth corresponding to the anti-retraction groove.

[0005] Preferably, the limiting protrusion has a circular arc shape in cross-section and is radially disposed on the outer side of the capsule body.

[0006] Preferably, the cross-sectional shape of the guide cone is an isosceles triangle, and the cross-sectional shape of the anti-retraction groove is a right triangle.

[0007] Preferably, the capsule body, the limiting protrusion, the guide cone, and the anti-retraction groove are an integral structure.

[0008] Preferably, the capsule cap, the limiting ring groove, the inner limiting groove, and the anti-backward teeth are an integral structure.

[0009] Preferably, the height of the inner opening of the inner limiting groove is greater than the height of the outer opening.

[0010] Preferably, the bottom of the inner limiting groove is integrally provided with a thickened bottom ring.

[0011] The beneficial effects of this utility model are as follows: This utility model integrates the capsule body, limiting protrusion, guide cone, anti-retraction groove, capsule cap, limiting ring groove, inner limiting groove, and anti-retraction teeth together. After experimental optimization, it can achieve inner end limiting by the anti-retraction teeth at the lower part of the inner limiting groove in conjunction with the anti-retraction groove at the bottom of the capsule body. At the same time, the limiting protrusion on the outer side of the capsule body in conjunction with the limiting ring groove on the inner side of the capsule cap provides sealing and limiting. The connection part is not easy to loosen or detach, and the sealing effect is stable.

[0012] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. [Attached Image Description]
