Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of capsules, in particular to a hollow capsule. Background Art
[0002] Some medicines are in the form of powders or granules that are irritating to the esophagus and gastric mucosa, or have a bad taste, are easy to volatilize, are easily decomposed by saliva in the mouth, and are easily inhaled into the trachea. Therefore, during manufacturing, the medicines are placed in hollow capsules, which not only protects the medicinal properties of the medicine from being destroyed, but also protects the digestive organs and respiratory tract. Removing the capsule shell may cause drug loss, drug waste, and reduced efficacy.
[0003] Most of the existing hollow capsules are made of gelatin. Traditional gelatin hollow capsules are mainly composed of a capsule cap and a capsule body. The connection strength between the capsule body and the capsule cap of the hollow capsule is low, and it is easy to be pulled apart, causing the medicine contained therein to scatter, affecting the use of the medicine, and posing a safety hazard. In addition, the structural strength of the connection between the capsule body and the capsule cap of the hollow capsule is low. When the connection is squeezed, it is easy to deform, destroying the stable state of the medicine contained in the hollow capsule, or causing the medicine to spill out, affecting the use of the capsule and the medicine inside it.

[0033] Furthermore, a plurality of circular grooves 12 are formed on the left surfaces of the first reinforcement shell 3 and the connection shell 5 .
[0034] Furthermore, by providing a plurality of circular grooves 12, the overall mass of the first reinforcing shell 3 and the connecting shell 5 is reduced, and the difficulty of digesting the first reinforcing shell 3 and the connecting shell 5 is reduced, thereby reducing the difficulty of digesting the capsule and improving the use effect of the capsule.
