Abstract

A cosmetic container applicable for a water-based formula, comprising a top cover (1), an inner cover (2), a sleeve cylinder (3), a material cup (4), a threaded rod (5), a threaded sleeve (6), and a base (7). The material cup (4), the threaded rod (5), the sleeve cylinder (3), and the threaded sleeve (6) are arranged together within the base (7). When the top cover (1) and the base (7) are fitted, the inner cover (2) is tightly fitted to an extremity of the sleeve cylinder (3). The inner cover (2), the sleeve cylinder (3), and the material cup (4) are either of a PP material or a PBT material. Because the PP material and the PBT material are fully food-grade, economic, and environmentally-friendly materials, this ensures that a cosmetic of a water-based formula is prevented from being contaminated by a conventional material plastic, the space for accommodating the cosmetic surrounded by the top cover (1) and the base (7) when fitted with each other is a sealed space, thus ensuring the cosmetic raw materials are prevented from deterioration or changes due to oxidization by air, and facilitating storage. The cosmetic container is applicable as a container for cosmetics such as lip gloss, eyeliner, lipstick, liquid foundation, and lotion.

Description

Cosmetic container for water-based formulations

Technical field

This invention relates to the field of cosmetic containers, and more particularly to cosmetic containers suitable for use in water based formulations.
