Apparatus and method of manufacturing and labeling plastic wares
View Patent ↗An apparatus and method of manufacturing and labeling plastic wares comprising durable acrylic labels that are integrated into a surface of the plastic wares.
1. A method of manufacturing and labeling plastic wares comprising:
providing a mold comprising a cavity component and a core component, wherein the cavity component has been subjected to treatment so that plastic wares formed in the mold have a plurality of protrusions extending from the outer surface of the plastic ware;
disposing a label in a gap between the cavity component and the core component so that the label is disposed against an inside surface of the cavity component;
injecting melted plastic into the gap between the core component and the label;
solidifying the melted plastic to form the plastic ware, so that the label is incorporated into the outer surface of the plastic ware and protrudes away from the outer surface of the label at the protrusions.
2. The method of manufacturing and labeling plastic wares of claim 1 wherein the treatment comprises acid etching.
3. The method of manufacturing and labeling plastic wares of claim 1 wherein the treatment comprises sandblasting.
4. The method of manufacturing and labeling plastic wares of claim 1 wherein the protrusions comprises bumps on the outer surface of the plastic ware.
5. The method of manufacturing and labeling plastic wares of claim 4 wherein the bumps are about 1 mm in diameter and are about 5 mm apart from each other.
6. The method of manufacturing and labeling plastic wares of claim 1 wherein the outside surface of the core component has been subjected to polishing.
7. The method of manufacturing and labeling plastic wares of claim 6 wherein the step of injecting comprises melting plastic pellets to create the melted plastic.
8. The method of manufacturing and labeling plastic wares of claim 1 further comprising printing art work on the inside surface of the label so that ink comprising the art work is in direct contact with the plastic.
9. The method of manufacturing and labeling plastic wares of claim 8 wherein the printing step comprises reverse printing.
10. The method of manufacturing and labeling plastic wares of claim 8 wherein the ink is heat resistant.
11. The method of manufacturing and labeling plastic wares of claim 1 wherein the label is clear.
12. The method of manufacturing and labeling plastic wares of claim 7 further comprising printing art work on the outer surface of the label.
13. The method of manufacturing and labeling plastic wares of claim 1 wherein the plastic is clear or transparent when the plastic wares are finished.
14. The method of manufacturing and labeling plastic wares of claim 11 further comprising straight printing art work on an inside surface of the label.
15. The method of manufacturing and labeling plastic wares of claim 1 further includes the step of cooling the mold prior to the injecting step.
