1. Field of the Invention

The present invention relates to a screw cap, and more particularly to a non-dispensing multilayer multipart decorative screw cap.

2. Description of Related Art

Drink bottles or containers that house water or other potable beverages can include a screw cap. Most screw caps are designed to seal containers, most commonly bottles and jars, to keep their contents secure and protected. Other screw caps may also include other functional parts such as a spout or a nozzle to control the dispensing of the contents of a container. Alternatively, or in addition, a handle or a carrying strap may be included making it easier to carry and transport a container. As a result, the screw caps currently available in the market are all functional, i.e., for sealing, dispensing, and/or facilitating the carrying of a container. Consequently, most screw caps have a monotonous appearance and have neither beauty nor uniqueness due to lack of decorative design elements.
Currently, no screw caps on the market incorporate creative decorative designs that offer stylish and versatile appearances to express a user's personal taste, style or personality. Accordingly, there is a need for improved screw caps to provide such unique, diversified and creative decorative designs.
