A pad body integrally molded from a thermoplastic resin foam material with high compressibility includes a foam absorbent body, an outer film layer formed on an outer portion of the foam absorbent body, and a pull string connected to the outer film layer. A tampon is also disclosed, and includes a tubular sleeve unit and the pad body. The tubular sleeve unit includes an outer tube and a push rod. The foam absorbent body and the outer film layer constitute an absorption section of the pad body. The absorption section is constrained by the outer tube in a compressed state, and is transformed to an expanded state when pushed by the push rod to move out of the receiving hole via the exit opening.

1. A pad body integrally molded from a thermoplastic resin foam material with high compressibility and comprising a foam absorbent body, an outer film layer formed on an outer portion of said foam absorbent body, and a pull string connected to said outer film layer, said foam absorbent body and said outer film layer constituting an absorption section of said pad body, said outer film layer having a plurality of absorption holes communicating said foam absorbent body with the outside, said absorption section being transformable from a compressed state to an expanded state, said absorption section having a connecting end portion connected to said pull string, a top end portion opposite to said connecting end portion, and an intermediate portion between said connecting end portion and said top end portion.

2. The pad body as claimed in claim 1, wherein said outer film layer covers a majority of said foam absorbent body, but not a top portion thereof.

3. The pad body as claimed in claim 1, wherein said absorption section has a conical shape in the expanded state, and has a width that gradually decreases from said top end portion to said connecting end portion.

4. The pad body as claimed in claim 1, wherein said absorption section has a cylindrical shape in the expanded state.

5. The pad body as claimed in claim 1, wherein the thermoplastic resin foam material is selected from, at least one of polyurethane, polyethylene, polypropylene, and polyethylene terephthalate.

6. A tampon comprising: a tubular sleeve unit including an outer tube that defines a receiving hole, and a push rod movably disposed in said receiving hole, said outer tube having a tubular main portion, a head portion connected to said tubular main portion, and a bottom portion opposite to said head section, said head portion having a hemispherical shape and having an exit opening communicating said receiving hole with the outside, and plurality of angularly spaced-apart claw pieces connected to a top periphery of said tubular main portion and surrounding said exit opening, each of said claw pieces having a connecting end connected to said top periphery of said tubular main portion, and a free end opposite to said connecting end, said claw pieces being movable between a closed state, in which said free ends of said claw pieces are close to each other, and an open state, in which said free ends of said claw pieces are moved away from each other; and a pad body integrally molded from a thermoplastic resin foam material with high compressibility and including a foam absorbent body, an outer film layer formed on an outer portion of said foam absorbent body, and a pull string connected to said outer film layer, said foam absorbent body and said outer film layer constituting an absorption section of said pad body, said absorption section being removably disposed in said receiving hole of said outer tube, said outer film layer having a plurality of absorption holes communicating said foam absorbent body with the outside, said absorption section being transformable from a compressed state to an expanded state, said absorption section being constrained by said outer tube in the compressed state, and being transformed from the compressed state to the expanded state when pushed by said push rod to move out of said receiving hole via said exit opening, said absorption section having a connecting end portion connected to said pull string, a top end portion opposite to said connecting end portion, and an intermediate portion between said connecting end portion and said top end portion.

7. The tampon as claimed in claim 6, wherein said outer film layer covers a majority of said foam absorbent body, but not a top portion thereof.

8. The tampon as claimed in claim 6, wherein said absorption section has a conical shape in the expanded state, and has a width that gradually decreases from said top end portion to said connecting end portion.

9. The tampon as claimed in claim 6, wherein said absorption section has a cylindrical shape in the expanded state.

10. The tampon as claimed in claim 6, wherein the thermoplastic resin foam material is selected from at least one of polyurethane, polyethylene, polypropylene, and polyethylene terephthalate.
