Patent Searching and Data

Document Type and Number:
WIPO Patent Application WO/2018/034357
Kind Code:
The present invention relates to a double cosmetic container which has an inner container and an outer container formed simultaneously and integrally by means of blow molding, and a method for manufacturing same. Manufacturing procedures for an existing double cosmetic container not only are inconvenient but also require a separate coating work for the inner side of an outer container. Therefore, the manufacturing cost increases and the manufacturing method is not environmentally friendly since various chemicals are used for the coating. For a solution to the problem, the present invention provides a double cosmetic container having an outer container formed on the outer side of an inner container in which cosmetic contents are filled. The inner container and the outer container are integrally formed by means of simultaneously heating an inner preform and an outer preform, which comprise the same synthetic resin material, so as to have a common melting point, and simultaneously expanding same by means of blow molding. Therefore, since the present invention has the inner container and the outer container integrally attached and formed, the inner container plays the role of the coating for the inner side of the outer container and thus a traditional coating work can be omitted. Therefore, procedures are shortened and a cosmetic container can be manufactured in an environmentally-friendly way since chemicals for the coating are not required.
