Abstract

A synthetic resin hollow body which includes a hollow molding body made of a resin, the hollow molding body capable of holding a liquid material, and a resin sheathing body formed outside the hollow molding body in an integrating manner with the hollow molding body, wherein the resin sheathing body is made of a highly transparent synthetic resin having a total ray transmittance of at least 80%. The synthetic resin hollow body can exhibit a satisfactory decorating property and a satisfactory recycle property and is hardly damaged. In addition, the product cost and operation cost can be suppressed.

Claims (21)

1. A synthetic resin hollow body (A), comprising:

a hollow molding body (a) made of a resin, the hollow molding body (a) capable of holding a liquid material; and

a resin sheathing body formed outside the hollow molding body (a) in an integrating manner with the hollow molding body (a),

wherein the resin sheathing body is welded to an external surface of the hollow molding body (a) so that a boundary line between the resin sheathing body and the hollow molding body (a) is not visible.

2. The synthetic resin hollow body (A) as defined in claim 1 , wherein the hollow molding body (a) is made of a highly transparent synthetic resin having a total ray transmittance of at least 80%.

3. The synthetic resin hollow body (A) as defined in claim 1 further comprising a cap member, wherein the cap member is made of a highly transparent synthetic resin having a total ray transmittance of at least 80%.

4. The synthetic resin hollow body (A) as defined in claim 1 , wherein the resin sheathing body is made of an ionomer of an ethylene acrylic acid copolymer, an ethylene methacrylic acid copolymer, or combinations thereof.

5. The synthetic resin hollow body (A) as defined in claim 1 , wherein the resin sheathing body is colored or has no color.

6. The synthetic resin hollow body (A) as defined in claim 1 , wherein a light reflecting powder is dispersed in the resin sheathing body.

7. The synthetic resin hollow body (A) as defined in claim 1 , wherein the resin sheathing body is made of a transparent synthetic resin, a sheet of the transparent synthetic resin having a total ray transmittance of at least 80% measured according to JIS K7105.

8. The synthetic resin hollow body (A) as defined in claim 1 , wherein the hollow molding body (a) is a thin-walled molding body.

9. The synthetic resin hollow body (A) as defined in claim 1 , wherein a thickness of the resin sheathing body is at least 1 mm.

10. The synthetic resin hollow body (A) as defined in claim 1 , wherein the hollow molding body (a) is a hollow molding container.

11. The synthetic resin hollow body (A) as defined in claim 1 , wherein the hollow molding body (a) is a hollow molding container comprising one or more separate polymer layers selected from the group consisting of adhesive layers and barrier layers.

12. The synthetic resin hollow body (A) as defined in claim 1 , wherein the hollow molding body (a) is a hollow molding container with an adhesive layer on its outside for better adhesion to the resin sheathing body.

13. The synthetic resin hollow body (A) as defined in claim 1 , wherein the hollow molding body (a) comprises polyethylene, polypropylene, ionomer, polyester, polyamide, or combinations thereof.

14. The synthetic resin hollow body (A) as defined in claim 1 , wherein the hollow molding body (a) comprises polyethylene, polypropylene, or combinations thereof.

15. The synthetic resin hollow body (A) as defined in claim 1 , wherein synthetic resin hollow body (A) further comprises a cosmetic solution, a chemical, a mixed solution of an organic solvent and an aqueous component, or an organic solvent in the hollow molding body.

16. The synthetic resin hollow body (A) as defined in claim 1 , wherein synthetic resin hollow body (A) further comprises a cosmetic solution, a chemical, or a mixed solution of an organic solvent and an aqueous component.

17. The synthetic resin hollow body (A) as defined in claim 1 , wherein synthetic resin hollow body (A) further comprises a cosmetic solution.

18. The synthetic resin hollow body (A) as defined in claim 1 , wherein a thickness of the hollow molding body (a) is 0.1 mm to 10 mm.
