ABSTRACT:
FIELD OF THE INVENTION
The present invention is generally directed to a container or bottle. More particularly, the present invention is directed to a double chambered container that is capable of containing two separate liquids. In one embodiment, the chambers of the container are helical in shape and are connected by a top and an attachment device.
BACKGROUND OF THE INVENTION
In the past, all types of vessels having various shapes and functions have been proposed and used for holding liquids. One particular type of vessel, such as a drinking bottle, that is of current interest is a container or bottle that can contain more than one type of liquid. In addition to the useful benefit of containing more than one liquid, a double chambered container can also be of aesthetic interest. For example, a double chambered container can often spark the curiosity of consumers due to its unique appearance, particularly when each chamber houses a differently colored liquid or is, at least, made from differently colored halves.
A double chambered container can have various applications. For example, a double chambered bottle can be used to carry two different types of drinks. One example of such a bottle is the TWIN CUP® made by Sewon Industries, Inc. The TWIN CUP® is a double chambered drinking container that can hold more than one drink. Its two chambers are identical and line up along a flat edge on each half of a cylinder Using a straw, a consumer can use this container to drink one type of liquid for a period of time before switching to another. However, because the chambers contain edges that are parallel to each other, the chambers of the TWIN CUP® are not always sufficiently integrated so as to impart a completely stable product. In addition, consumers and advertisers often desire bottles with a more appealing aesthetic shape.
Thus, despite the benefits of such known containers, a need nevertheless exists for improved double-chambered containers. In particular, a need exists for a double-chambered container having chambers that can be better integrated to form a more stable bottle. Moreover, a need also exists for a double-chambered container having enhanced aesthetic qualities.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide a container having two chambers capable of receiving two different liquids.
It is another object of the present invention to provide a double-chambered container having enhanced aesthetic qualities.
Still another object of the present invention is to provide two chambers that can be attached in a manner such that the resulting container is sufficiently integrated.
Yet another object of the present invention is to provide a double-chambered container that includes chambers having helical surfaces.
It is another object of the present invention to provide a double-chambered container that can be connected by a top.
Another object of the present invention is to provide a double-chambered container having a top that includes one aperture over each chamber for receiving a straw.
Still another object of the present invention is to provide a double-chambered container that is further connected by an attachment device.
These and other objects of the present invention are achieved by providing a container having two chambers with helical surfaces. To form the container, the helical surfaces of each chamber can be placed adjacent to one another. As a result of such placement, threads located along the top portion of each chamber can become aligned. Thereafter, a top containing grooves can be screwed onto the threads of the chambers so that the chambers become connected. In addition to being connected by a top, the helical chambers of the present invention may, in some embodiment, also be connected by an attachment device. For example, in one embodiment, a snap is provided to connect the bottom portion of the chambers. In other embodiments, the connection is provided by a bottom cap.
In addition to attaching the chambers, a top of the present invention can also contain apertures adapted to receive a straw. In one embodiment, a top of the present invention includes apertures that an be positioned over each chamber such that liquid from each chamber can be utilized. As a result of the present invention, a consumer can drink different liquids from one container having two helically-shaped chambers.
Other objects, features and aspects of the present invention are discussed in greater detail below.
