1. A child protective packaging container, comprising:

a main body defining a main cavity therein for containing an article and having a bottom portion indented downwardly and an opening portion protruded upwardly,

a cap having a raised portion corresponding to a shape and a size of the opening portion and a receiving cavity inside the raised portion;

a safety button hidden by and received inside the receiving cavity of the raised portion of the cap for controlling an opening or a closing of the cap with respect to the main body; and

at least one sliding lock member connected to the safety button at a bottom side of the safety button.

2. The child protective packaging container according to claim 1 , wherein the cap has a base, two sliding lock members are provided and connected to the base at two opposite sides of the base of the cap, and the two sliding lock members are connected by a locking spring.

3. The child protective packaging container according to claim 2 , comprising a pair of matching thread members disposed at an inner wall of the cap and an outer wall of the opening portion respectively.

4. A method of use of the child protective packaging container according to claim 3 , comprising the steps of:

(a) cap closing operation by screwing the cap into the opening portion, pressing the cap gently and downwardly with an external force such that when the sliding lock member passes through the opening portion, the sliding lock member is compressed and contracted by an inner wall of the main body and simultaneously rotating the cap in a forward direction of the spiral thread of the thread member so that the thread member at the inner wall of the cap and the thread member at the outer wall of the opening portion are screwed together tightly, then stopping to apply the external force after the sliding lock member is entered to an inner side the main body through the opening portion so that the sliding lock member is in an expanded state and lock between the inner side of the main body and the opening portion, thus locking the cap and the main body at the inner side of the main body;

(b) cap opening operation by pressing the safety button with an external force so that the sliding lock member is contracted under the action of the external force and then the cap is unlocked from the inner side of the main body; and simultaneously rotating the cap in an opposite direction of the spiral thread of the thread member so that the sliding lock member is rotated to reach the opening portion and is compressed to contract by the inner wall of the opening portion; then releasing the safety button from pressing so that the safety button is spring back to a normal position; and rotating the cap continuously until the cap is unscrewed from the opening portion.

5. A child protective packaging container, comprising:

a main body defining a main cavity therein for containing an article and having a bottom portion indented downwardly and an opening portion protruded upwardly;

a cap having a raised portion corresponding to a shape and a size of the opening portion and a receiving cavity inside the raised portion;

a safety button hidden by and received inside the receiving cavity of the raised portion of the cap for controlling an opening or a closing of the cap with respect to the main body;

a spring inside the safety button; and

two sliding lock members connected to the safety button at a bottom side of the safety button; a based disposed at the cap and connected to the two sliding lock members at two opposite sides of the base of the cap; and a locking spring connecting the two sliding lock at two opposite ends.

6. The child protective packaging container according to claim 5 , comprising a pair of matching thread members disposed at an inner wall of the cap and an outer wall of the opening portion respectively.

7. The child protective packaging container according to claim 6 , wherein a top surface of the cap and a top surface of the safety button are flush with each other in a stationary state.

8. A method of use of the child protective packaging container according to claim 6 , comprising the steps of:

(a) cap closing operation by screwing the cap into the opening portion, pressing the cap gently and downwardly with an external force such that when the sliding lock member passes through the opening portion, the sliding lock member is compressed and contracted by an inner wall of the main body and simultaneously rotating the cap in a forward direction of the spiral thread of the thread member so that the thread member at the inner wall of the cap and the thread member at the outer wall of the opening portion are screwed together tightly, then stopping to apply the external force after the sliding lock member is entered to an inner side the main body through the opening portion so that the sliding lock member is in an expanded state and lock between the inner side of the main body and the opening portion, thus locking the cap and the main body at the inner side of the main body;

(b) cap opening operation by pressing the safety button with an external force so that the sliding lock member is contracted under the action of the external force and then the cap is unlocked from the inner side of the main body; and simultaneously rotating the cap in an opposite direction of the spiral thread of the thread member so that the sliding lock member is rotated to reach the opening portion and is compressed to contract by the inner wall of the opening portion; then releasing the safety button from pressing so that the safety button is spring back to a normal position; and rotating the cap continuously until the cap is unscrewed from the opening portion.

9. A method of use of the child protective packaging container, which comprises a main body defining a main cavity therein for containing an article and having a bottom portion indented downwardly and an opening portion protruded upwardly; a cap having a raised portion corresponding to a shape and a size of the opening portion and a receiving cavity inside the raised portion, and a safety button hidden by and received inside the receiving cavity of the raised portion of the cap for controlling an opening or a closing of the cap with respect to the main body, comprising the steps of:

(a) cap closing operation by screwing the cap into the opening portion, pressing the cap gently and downwardly with an external force such that when the sliding lock member passes through the opening portion, the sliding lock member is compressed and contracted by an inner wall of the main body and simultaneously rotating the cap in a forward direction of the spiral thread of the thread member so that the thread member at the inner wall of the cap and the thread member at the outer wall of the opening portion are screwed together tightly, then stopping to apply the external force after the sliding lock member is entered to an inner side the main body through the opening portion so that the sliding lock member is in an expanded state and lock between the inner side of the main body and the opening portion, thus locking the cap and the main body at the inner side of the main body;

(b) cap opening operation by pressing the safety button with an external force so that the sliding lock member is contracted under the action of the external force and then the cap is unlocked from the inner side of the main body; and simultaneously rotating the cap in an opposite direction of the spiral thread of the thread member so that the sliding lock member is rotated to reach the opening portion and is compressed to contract by the inner wall of the opening portion; then releasing the safety button from pressing so that the safety button is spring back to a normal position; and rotating the cap continuously until the cap is unscrewed from the opening portion.
