Abstract: A method for fabricating a bubbler is disclosed, which is performed by laminating a polypropylene (PP), PE, CPET film onto a paper material surface to form a PP, PE, CPET film, and then screen printing or coating a hydrophilic polyurethane (PU) material onto another surface of the paper material to form a hydrophilic PU foaming material, then color printing a print material onto the hydrophilic foaming film to form a pattern layer, trimming the paper material to form a paper plate having a desired range, and forming the paper plate as an utensil, and enabling the hydrophilic PU foaming film to form a three dimensional pattern area on a surface of the utensil by being heated and thus foaming with a heating temperature presenting when the utensil is formed, whereby a three dimensional pattern area may be directly formed onto a surface of a utensil.

Abstract: A foaming paper cup heating structure is disclosed, which comprises a heating mechanism, comprising a cavity, and a plurality of heating units disposed within the cavity; and a pick-up and place mechanism, disposed corresponding to the heating units within the cavity. As such, a pick-up and place mechanism is used to grip a plurality of paper cups coated a foaming material thereon, the foaming material is continuously heated within the heating mechanism to foam to present a form, so that the paper cup may achieve the efficacies of a rapid heating, a uniform heating, a rapid producing, and an enhanced production yield.

Abstract: A method for fabricating a heat isolative paper container, which provides a paper board having a plurality of seams at a circumference thereof, and then a heat isolative material containing the hollow body is coated locally on at least a surface of the paper board and exempted from the seams. The container is then folded up as a container, and the container is heated, so that a heat isolative layer is provided on the surface of the container and has a heat isolative coefficient ranging from 0.003 to 0.05. The heat isolative material is made of polyurethane, PU, acrylic resin, polyethylene (PE), polypropylene (PP), polylactide (PLA), and epoxy. In this manner, the heat isolative material containing the hollow body may achieve the efficacies of a reduced volume, a reduced transportation cost, and an improved heat isolative effect, by using an isolative layer containing a hollow body.

Abstract: A foam container is made. A foam material is uniformly coated on at least one surface of the container. The foam material is formed by mixing a PU aqueous liquid, a defoamer, a thickener, a foaming agent, an adhesive and an additive. Fabrication speed is improved with reduced power consumption. The container thus fabricated has increased thickness, good hydrolysis resistance, good adhesion (without crumbs dropped), good heat insulation, good scratch resistance, good abrasion resistance, good printability and good workability for continuous production.

Abstract: A method for securing a bottom piece to a paper-made container forms first and second glue layers in one injection molding process. The method includes a mold set has a first concavity located corresponding to the open top of the paper-made container and communicating with a pouring path of an entrance via a first passage in the mold. A second concavity is defined in the mold and communicates with a second passage which communicates with the pouring path via a hole defined through the bottom piece. The two glue layers are formed within one molding process while the bottom piece is connected to the paper-made container.
