Sealing device for capsule product and operation method thereof

An operation method of a sealing device for a capsule product, comprising:

• placing a cup body of a capsule shell of the capsule product in an accommodating groove of a base of the sealing device for the capsule product, supporting a flange of the cup body on an annular protrusion of the base;
• placing a powdered product into a receiving groove of the cup body, or covering the base by a cover body of an upper cover of the sealing device for the capsule product and placing the powdered product into the receiving groove through a through hole of the cover body;
• removing the cover body, abutting an outer wall surface of a sealing piece of the capsule shell against an inner wall of a positioning baffle of the base, and attaching the sealing piece to the flange;
• and
• covering the base by the upper cover of the sealing device of the capsule product, so as to seal and attach the sealing piece to the flange;
• wherein the capsule product comprises the capsule shell and the powdered product contained in the capsule shell, the capsule shell comprises the cup body and the sealing piece, the cup body defines the receiving groove and comprises the flange at a top portion thereof, the flange extends in a radial direction, the sealing piece is attached to the flange and is configured to seal the receiving groove;
• the sealing device for the capsule product comprises the base and the upper cover;
• the base defines the accommodating groove, the accommodating groove has an upper opening, the annular protrusion is disposed on an upper surface of the base and is annularly disposed at an outer periphery of the upper opening of the accommodating groove, the accommodating groove is configured to accommodate the cup body, the annular protrusion is configured to support the flange, the base comprises the positioning baffle disposed at one side of the accommodating groove, and the positioning baffle is configured to limit the sealing piece;
• and
• the upper cover comprises the cover body and a top cover, the cover body is detachably connected to the base, and a pressing portion is disposed on a bottom portion of the cover body, the cover body defines the through hole at an inner side of the pressing portion, the top cover is detachably connected to a top portion of the cover body for covering or exposing the through hole.

A sealing device for sealing a capsule product, the capsule product comprising a sealing piece configured to seal the capsule product, comprising:

• a base;
• and
• an upper cover;
• wherein the base defines an accommodating groove having an upper opening, and the base further comprises a positioning baffle disposed at one side of the accommodating groove;
• wherein the positioning baffle protrudes upwards from a side wall of the base and is configured to allow an outermost edge of the sealing piece along a thickness of the sealing piece to abut against an inner sidewall of the positioning baffle facing towards the accommodating groove, wherein the sealing piece is operative to be placed substantially perpendicular to the positioning baffle and abut against the inner sidewall of the positioning baffle for positional alignment;
• and wherein the upper cover is detachably connected to the base, a pressing portion is disposed on a lower surface of the upper cover;
• wherein an annular protrusion is disposed on an upper surface of the base and is annularly disposed at an outer periphery of the upper opening of the accommodating groove;
• wherein in a radial direction, a distance between an inner wall surface of the positioning baffle and an outer wall surface of the annular protrusion is not less than 0.1 mm and is not greater than 5 mm.
