Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hollow capsules, in particular to a liquid-filled hollow capsule. Background Art
[0002] Liquid-filled hollow capsules are two-section capsules designed for filling and sealing liquids and semi-solid preparations. They are also called Licaps capsules and are a new type of capsule dosage form, particularly suitable for filling liquids and semi-solid drugs or health products.
[0003] When combining the capsule shell and the capsule cap of the existing liquid-filled capsule, the outer protrusion on the shell is usually inserted into the inner protrusion on the cap body by external force to form a tight locking structure, thereby achieving a sealing effect. However, relying solely on the traditional protrusion locking structure will make the connection stability between the capsule shell and the capsule cap relatively general, so there is a need for a hollow capsule with enhanced connection stability based on the protrusion locking structure. Utility Model Content
[0004] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art and to provide a liquid-filled hollow capsule that can solve the problem that the connection stability between the capsule shell and the capsule cap is relatively general when relying solely on the traditional protruding locking structure.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a liquid-filled hollow capsule, comprising a capsule cap and a capsule shell, wherein the outer surface of the capsule cap is slidably connected to the inner wall of the capsule shell, the outer surface of the capsule cap is provided with an external protrusion, the external protrusion is an annular protrusion structure, the surface of the external protrusion is provided with a plurality of protrusion blocks, the inner wall of the capsule shell is provided with a plurality of connecting grooves, the inner wall surface of the capsule shell is provided with a plurality of inner protrusions, the plurality of inner protrusions are grouped in two, and each group of inner protrusions is arranged in a circular array between the corresponding two connecting grooves.
[0006] Preferably, the interiors of the plurality of connecting grooves are respectively slidably fitted with the outer surfaces of the plurality of raised blocks.
[0007] Preferably, the outer surface of the outer protrusion is provided with a plurality of anti-slip protrusions.
[0008] Preferably, the plurality of anti-slip protrusions are arranged in groups of two, and each group of anti-slip protrusions is arranged in a circular array between two corresponding protrusion blocks.
[0009] Preferably, outer surfaces of the plurality of anti-slip protrusions are in sliding contact with outer surfaces of the plurality of inner protrusions respectively.
[0010] Preferably, outer surfaces of the plurality of anti-slip protrusions are in sliding contact with outer surfaces of the plurality of inner protrusions respectively.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] 1. The liquid-filled hollow capsule forms a protrusion locking structure by contacting the outer protrusion with the inner protrusion. Then, by setting the anti-slip protrusion, the outer protrusion and the inner protrusion are not easy to slide when in contact and connected. Then, a certain fixing force is applied inside the multiple connection grooves by cooperating with the multiple protrusion blocks, so that the connection stability between the capsule cap and the capsule shell is further improved, thereby solving the general connection stability disadvantage of the traditional protrusion locking structure and further improving the practicality of the liquid-filled hollow capsule.

[0021] See also Figure 1-2 The utility model provides a technical solution: a liquid-filled hollow capsule, comprising a capsule cap 1 and a capsule shell 2. The outer surface of the capsule cap 1 is slidably connected to the inner wall of the capsule shell 2. The outer surface of the capsule cap 1 is provided with an external protrusion 3, and the external protrusion 3 forms an annular protrusion structure. The surface of the external protrusion 3 is provided with a plurality of protrusion blocks 4. The inner wall of the capsule shell 2 is provided with a plurality of connecting grooves 6. The inner wall surface of the capsule shell 2 is provided with a plurality of inner protrusions 7. The plurality of inner protrusions 7 are grouped in two, and each group of inner protrusions is arranged between the corresponding two connecting grooves 6 in an annular array.
[0022] Furthermore, the interiors of the plurality of connection grooves 6 are respectively slidably fitted with the outer surfaces of the plurality of protruding blocks 4 .
[0023] Furthermore, the outer surface of the outer protrusion 3 is provided with a plurality of anti-slip protrusions 5 , and the plurality of anti-slip protrusions 5 are arranged in a group of two, and each group of anti-slip protrusions 5 is arranged in a circular array between two corresponding protrusion blocks 4 .
[0024] Furthermore, outer surfaces of the plurality of anti-slip protrusions 5 are in sliding contact with outer surfaces of the plurality of inner protrusions 7 , respectively.
[0025] Furthermore, two compression-resistant plates 8 are fixedly connected to the inner wall of the capsule cap 1 and the capsule shell 2 .
[0026] Furthermore, when the capsule shell 2 and the capsule cap 1 are used in combination, the liquid is then loaded into the capsule shell 2, and the capsule cap 1 is then slid into the interior of the capsule shell 2. When the capsule cap 1 is slid into the capsule shell 2, the multiple protrusion blocks 4 are aligned with the interior of the multiple connecting grooves 6 and inserted. Then, through the setting of the multiple protrusion blocks 4 and the multiple connecting grooves 6, the multiple protrusion blocks 4 can respectively apply a certain fixing force inside the multiple connecting grooves 6, which makes the connection stability between the capsule cap 1 and the capsule shell 2 better. At the same time, after the capsule shell 2 and the capsule cap 1 are combined and connected, the outer protrusion 3 contacts the inner protrusion 7 to form a protrusion locking structure. Then, through the setting of the anti-slip protrusion 5, the outer protrusion 3 and the inner protrusion 7 are not easy to slide when in contact and connected, thereby further improving the connection stability between the capsule shell 2 and the capsule cap 1.
[0027] Furthermore, by providing the anti-compression plate 8 inside the capsule shell 2 and the capsule cap 1, the assembled hollow capsule can have good pressure resistance, so that the liquid-filled hollow capsule is not easily deformed by pressure, and the liquid inside the hollow capsule will not leak easily, further improving the practicality of the hollow capsule.
[0028] Furthermore, the outer protrusion 3 is in contact with the inner protrusion 7 to form a protrusion locking structure, and then the anti-slip protrusion 5 is set to prevent the outer protrusion 3 and the inner protrusion 7 from sliding when in contact and connected, and then the plurality of protrusion blocks 4 are used to apply a certain fixing force inside the plurality of connection grooves 6, so that the connection stability between the capsule cap 1 and the capsule shell 2 is further improved, thereby solving the general disadvantage of the connection stability of the traditional protrusion locking structure and further improving the practicality of the liquid-filled hollow capsule.
[0029] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
