DESCRIPTION OF THE PRIOR ART
Common cosmetic package containers filled with a cosmetic material of paste type are mostly of the design of an elongated tubular shape such as a lipstick container, and these containers, being of elongated tubular shape, often use special curves to modify their appearance for bringing more aesthetic effects. Despite the fact that these designs introduce more or less variations to the appearances of the containers, they still fail to create a distinct appearance that is completely different from an elongated shape; in other words, such elongated shape of appearance of containers can still cause confusions to users having other containers such as eyelash paste, eye gel and eye pencil that are also of the design of elongated shapes, in their purses or bags, making it inconvenient to retrieve the desired cosmetic tool. In addition, these conventional containers cannot be assembled with ease but require skilled techniques or aids of special machinery for filling in order to complete the filling process of the manufacturing. As a result, the overall manufacturing cost is high and the filling process requires higher level of technology and technique, which are the main reasons causing conventional lipstick products to be of high production costs. In view of different consumer groups, lipsticks provided for lip protection purposes are of greater population in their applications and usages; therefore, there is a need to provide a lipstick with ease of use and with an effectively reduced manufacturing cost while having a novel appearance that is entertaining and vivid and having a design that is convenient to the practical uses, easy to carry, and suitable for all consumers. In other words, there is a need to provide an improved cosmetic package container and, in particular, an improved structural design to a conventional container for lipstick products.
SUMMARY OF THE INVENTION
To overcome the drawbacks of the conventional cosmetic containers filled with a paste of cosmetic material, including difficulties to the assembly thereof due to complicated components, appearances lacking distinction from other cosmetic products, higher production costs, and other practical inconvenience in applications and usages, the inventor seeks to provide an improved cosmetic package container based on years of research and development. The improved cosmetic package container of the present invention is of a novel spherical shape constituting the outer appearance thereof and is of a three-piece assembly such that the above-mentioned drawbacks of the conventional cosmetic containers can be overcome.
An objective of the present invention is to provide: a cosmetic package container of three-piece assembly filled with a paste of cosmetic material such that the overall structural configuration of the container is simplified, the manufacturing process is facilitated and the overall production cost is lowered. An opening for filling of the paste of the cosmetic material is predefined at the bottom portion of the container such that the paste of the cosmetic material can be supplied into and solidified to be supported on the support frame of the central ring unit and such that the filling of the container of the present invention is facilitated for safety and economic purposes in order to achieve the practical applications and usages thereof.
Another objective of the present invention is to provide a cosmetic package container comprising a cap unit and a base unit respectively formed of a semi-spherical hollow shape, wherein the two units are each constructed of a double-layer structure with inner and outer layers having different materials to form the semi-spherical hollow shapes. The outer appearance of the container of the present invention can therefore be of any decorative designs and special shapes while having a novel and overall spherical shape that is appealing to the eye and is also of practical convenience to the use, such as retrieval of the container, and easy carrying of the container. In addition, the container of the present invention can also be entirely made of recycling plastics such that it has the merit of being environmentally friendly.
