Container

#The present invention relates to a container for storing viscous substances and is easily transportable. The viscous substances contained within the container can be extracted easily and completely without using any tools and without contact with the user.

#Containers that enclose viscous substances to be stored and transported are often inconvenient to use and most requires an applicator or other tools to extract the viscous substance. One conventional design utilizes a soft container that can be squeezed to extract the content through an opening that is generally sealed with a screwed-on cap. This design requires that the user first unscrew the cap to expose the opening and then apply pressure to the body of the container to force the content out through the opening. This design does not allow complete extraction of the content of the container due to the fact that as pressure is applied to the body of the container, the content would spread out and some would always remain in the container even if the container is almost empty.

#Another design uses a pump mechanism to physically pump the viscous substance through an opening that operates in conjunction with the pump mechanism such that as the pump mechanism is operated, the opening would open to allow the content to be extracted. This design is expensive to manufacture, and requires many small parts to be assembled.

#FIG. 1 shows the preferred embodiment of the container with two openings, one near each end of the elongated housing, and two pistons enclosing a viscous substance.

#FIG. 2 shows another embodiment of the container with two openings that are sealed with covers, one near each end of the elongated housing, and two pistons enclosing a viscous substance.

#FIG. 3 shows another embodiment of the container with one opening near one end of the elongated housing and a piston enclosing a viscous substance against the unopened end of the elongated housing with a scoring near the unopened end.

#FIG. 1 shows the preferred embodiment of the container. The container has an elongated housing 1 with two ends. An opening 3 is located near each of the two ends. Two pistons 2 are enclosed within the elongated housing 1 with approximately the same profile and dimension as the interior profile and dimension of the elongated housing 1 and located between the two openings 3. The two pistons 2 enclose and seal a viscous substance 4 between them within the elongated housing 1. The viscous substance 4 is sealed within the elongated housing 1 until the pistons 2 are urged either by air pressure or physical force to move from their initial position.

#The user may simply cover one of the opening 3 with their finger and apply pressure to the air chamber in the elongated housing 1 under the opening 3 at one end to generate an air pressure that will urge the pistons 2 to slide toward the other opening 3 at the opposite end of the elongated housing 1. Since fluids are incompressible, the viscous substance 4 will slide along the elongated housing 1 at the same rate and distance as the pistons 2. Once the piston 2 at the opposite end of the elongated housing 1 slides pass the opening 3 at the opposite end of the elongated housing 1, the viscous substance 4 will exit though the opening 3 at the opposite end of the elongated housing 1 for application. The piston 2 will also scrape the interior surfaces of the elongated housing 1 to completely extract all viscous substances 4 as it slides along the elongated housing 1. The user may also simply apply physical force by squeezing one end of the elongated housing 1 and physically push the piston 2 to slide toward the other end of the elongated housing 1 to achieve the same result.

#FIG. 2 shows another embodiment of the container of FIG. 1 wherein each of the two openings 3 of the preferred embodiment is covered with a cover 5. The cover 5 will further seal the air chambers under the openings 3 to prevent contaminants from entering into the elongated housing 1 and results in a completely sealed elongated housing 1.
