Improved capsule and packaging method

Abstract

The invention belongs to the technical field of capsule manufacturing, and particularly discloses an improved capsule and a packaging method thereof. The improved capsule comprises a hollow body and ahollow cap arranged outside the hollow body in a sleeving mode, one end of the hollow cap is closed, the other end of the hollow cap is open, and a first cap locking ring and a second cap locking ring are designed on the wall face of the hollow cap;one end of the hollow body is closed, and the other end of the hollow body is opened; two annular cones with different tapers, a straight line sectionand a body locking ring are designed on the wall surface, close to the open end, of the hollow body; a vent groove and a jet ring are further designed on the wall face of the hollow body, and the jetring and the opened end of the hollow cap form a gap allowing sealing liquid to pass through when the hollow body and the hollow cap are completely locked. The capsule provided by the invention can allow excessive air to overflow from the interior of the capsule during assembly, can prevent air in the capsule from overflowing during subsequent sealing of the capsule, and has the advantages of convenience and reliability during assembly, good sealing performance after assembly and the like.

Description

technical field [0001] The invention belongs to the technical field of capsule manufacturing, and more specifically relates to an improved capsule and a packaging method. Background technique [0002] Capsules are capsules made of special film-forming materials (such as gelatin, cellulose, polysaccharides, etc.) for containing contents (such as powder, granule, tablet, pill, semi-solid, liquid, etc.) , which are generally divided into hard capsules and soft capsules, and hard capsules are also called hollow capsules, which are composed of two parts: the body and the cap. [0003] The hard capsules are in a pre-assembled state after manufacture, and the pre-assembled capsules are conveyed to the filling machine without the risk of separation during filling to achieve the filling of the contents. In the filling machine, the filling of the content is generally achieved by the following steps: firstly, the cap is removed from the body, then a certain dose of content is filled i...

Problems solved by technology

[0004] However, when the capsule is finally closed after the above-mentioned filling, the capsule structure cannot isolate the internal and external air circulation, and the internal air will overflow from the capsule during subsequent sealing and damage the seal.
