A sealing cap includes a cap unit, a knob and at least one guiding mechanism. The cap unit includes a first cap body formed with a through hole extending along an axis, a second cap body, and a resilient gasket sleeved on the second cap body. The knob has a pressing portion abutting against the first cap body, and an insertion portion projecting into the through hole. The guiding mechanism includes an abutting member disposed on one of the second cap body and the insertion portion, and a guiding member having an inclined surface disposed on the other one of the second cap body and the insertion portion. Rotation of the knob causes the abutting member to slide on the inclined surface, and moves the second cap body between an opening position and a sealing position.

1. A sealing cap adapted for being detachably mounted on a container and sealing an opening of the container, said sealing cap comprising: a cap unit that includesa first cap body adapted for being detachably mounted on the container and formed with a through hole that extends along an axis (A),a second cap body disposed adjacent to said first cap body, anda resilient gasket sleeved on said second cap body;a knob that is rotatable about the axis (A) and that hasa pressing portion abutting against one side of said first cap body opposite to said second cap body, andan insertion portion projecting from said pressing portion into said through hole; andat least one guiding mechanism that includes an abutting member disposed on one of said second cap body of said cap unit and said insertion portion of said knob, and a guiding member disposed on the other one of said second cap body and said insertion portion, said guiding member having an inclined surface that extends spirally about the axis (A), said abutting member abutting slidably against said inclined surface to engage telescopically said first cap body with said second cap body;wherein rotation of said knob causes said abutting member to slide on said inclined surface, and moves said second cap body relative to said first cap body between an opening position, where said second cap body is away from said first cap body, and a sealing position, where said second cap body is close to said first cap body, so that said resilient gasket is adapted to be urged to resiliently deform to abut tightly against an inner surface of the container, thereby hermetically sealing the opening of the container;wherein said second cap body has a base portion that is spaced apart from said first cap body, said resilient gasket being sleeved on said base portion of said second cap body, anda protruding portion that projects from said base portion along the axis into said through hole of said first cap body;wherein said abutting member of said guiding mechanism is disposed on one of said protruding portion of said second cap body and said insertion portion of said knob, said guiding member of said guiding mechanism being disposed on the other one of said protruding portion and said insertion portion; andwherein said sealing cap further comprises a resilient member that has opposite ends abutting respectively against said first and second cap bodies for biasing said second cap body away from said first cap body. 2. The sealing cap as claimed in claim 1, wherein: said inclined surface of said guiding member has a first end and a second end that are respectively proximate to and distal from said first cap body;when said second cap body is at the sealing position, said abutting member is at said second end of said inclined surface, and said resilient member is compressed by said second cap body to store a resilient force;during movement of said second cap body from the sealing position to the opening position, said resilient member releases the resilient force for facilitating movement of said second cap body; andwhen said second cap body is at the opening position, said abutting member is at said first end of said inclined surface and said resilient member is uncompressed. 3. The sealing cap as claimed in claim 1, wherein said protruding portion of said second cap body has an inner surface that surrounds the axis (A) and that defines an insertion hole, said insertion portion of said knob extending into said through hole of said first cap body and said insertion hole, said abutting member of said guiding mechanism being disposed on one of said inner surface of said second cap body and said insertion portion of said knob, said guiding member of said guiding mechanism being disposed on the other one of said inner surface and said insertion portion. 4. The sealing cap as claimed in claim 3, wherein said first cap body has a base section and a protruding section that projects from said base section along the axis (A) toward said base portion of said second cap body and that defines said through hole, said protruding portion of said second cap body extending into said protruding section of said first cap body. 5. The sealing cap as claimed in claim 4, wherein said protruding portion of said second cap body further has an outer surface opposite to said inner surface, said sealing cap further comprising at least one limiting mechanism that has a limit groove extending in the direction of the axis (A), and a limit block engaging slidably said limit groove such that said second cap body is limited to move relative to said first cap body along the axis (A), said limit block being provided to one of said protruding section of said first cap body and said outer surface of said second cap body, said limit groove being provided to the other one of said protruding section and said outer surface. 6. The sealing cap as claimed in claim 1, further comprising at least one limiting mechanism that includes a limit groove and a limit block that engages slidably said limit groove such that said second cap body is limited to move relative to said first cap body along the axis (A), said limit block being provided to one of said first cap body and said second cap body, said limit groove being provided to the other one of said first cap body and said second cap body. 7. The sealing cap as claimed in claim 6, comprising a plurality of said limiting mechanisms, said limit block of each of said limiting mechanisms being provided to said first cap body, said limit groove of each of said limiting mechanisms being provided to said second cap body. 8. The sealing cap as claimed in claim 1, comprising a plurality of said guiding mechanisms, said abutting member of each of said guiding mechanisms being disposed on said insertion portion of said knob, said guiding member of each of said guiding mechanisms being disposed on said second cap body.
