BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a container with an ear. The container is made of a synthetic resin. A method for manufacturing the container is also disclosed and described.
2. Description of the Related Art
Conventionally, a cup-shaped container made of synthetic resin comprises a bottom part and a cylindrical drum part provided on the periphery of the bottom part and an opening at a top surface. Such containers are known to have a unified ear to facilitate handling or have no ear.
A container having an ear is more convenient than the one having no ear because it is easier to carry the container. This facilitates carrying hot contents, such as coffee. However, in the manufacture, transportation, or storage, the container having an ear has the disadvantage in that the ear hinders efficient stacking and piling making the stack bulky. Particularly, in case of a container whose ear projects outwardly, it is very inconvenient to stack the containers. This is especially evident when stacking these containers in an automatic vending machine or when bringing the containers to a picnic.
SUMMARY OF THE INVENTION
It is an object of the invention to provide a container being made of synthetic resin and having an ear. The ear of the present invention allows efficient stacking of the containers. Another object of the invention is to provide a method for manufacturing the container.
According to one embodiment of invention, container comprises a bottom part, a drum part extending upwardly from the periphery of the bottom part, and an ear divided and formed by a kerf. The ear is united with the drum part and is able to extend away from the drum part. A synthetic resin film adheres to the drum part to cover at least the ear forming part while covering the kerf in a liquid tight manner.
Other objects of the invention are achieved by providing the ear able to easily extend away from the drum part. A thin folding line on a boundary between the ear and the drum parts permits easy extension of the ear.
Further, the container can be constructed so the bottom and the drum parts are molded as one piece. The ear is formed on the drum part by providing a kerf on the drum. The synthetic resin film covers over the ear and kerf parts and is adhered to the inside of the drum part in a liquid tight manner.
Another object of the invention can be recognized by constructing the container so the bottom and the drum parts are formed as one piece. The ear is formed on the drum part by providing a kerf on the drum. The synthetic resin film is formed in cylindrical shape and has openings at its-top and bottom. The film covers all of the inner surface of the drum part and is adhered to the inner surface of the drum part. In this case, however, the film is not adhered to the ear.
A further object of the invention is achieved by constructing the container so that the bottom and the drum parts are formed as one piece. The ear is formed on the drum part by providing a kerf on the drum. The synthetic resin film is formed in a cylindrical shape and has a bottom and an opening at its top. The film covers all of the inner surface of the drum part and the inner surface of the bottom part and is adhered to the inner surface of the drum.
Furthermore, the container can be constructed so the ear is formed by providing a kerf on the cylindrical drum part. The drum part has openings at its top and bottom. The bottom of a synthetic cylindrically shaped resin film, which has a bottom and an opening on its top, covers all of the inner surface of the drum part and the inner surface of the bottom part.
A further object of the invention is achieved by molding the container in a design including printing a pattern on the periphery of the cylindrically-shaped synthetic resin film and adhering the film to a transparent inner surface of the cylindrical drum part. The film can be formed as multi-layered films. The printed layer can be provided as the intermediate layer of the multi-layered films to form a patter
