DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Figure 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.
Figure 2 shows another embodiment of the container of figure 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.
Figure 3 shows another embodiment of the container. The container has an elongated housing 1 with two ends. An opening 3 is located near one end of the elongated housing 1.
A piston 2 is 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 near the same end as the opening 3. The piston 2 enclose and seal a viscous substance 4 between the piston 2 and the other end of the elongated housing 1 without any openings but with a scoring 6 such that the elongated housing 1 can be broken open at the scoring 6 when bent. The viscous substance 4 is sealed within the elongated housing 1 until the elongated housing 1 is broken open at the scoring 6 and the piston 2 is urged either by air pressure or physical force to move from its initial position to force the viscous substance 4 out of the elongated housing 1.
Another variation of the embodiment shown in figure 3 utilize a pressure sensitive opening instead of a scoring 6 such that when the piston 2 is urged either by air pressure or physical force to move from its initial position to force the viscous substance 4 against the other end of the elongated housing 1 that is sealed with the pressure sensitive opening, the pressure sensitive opening will open due to the resulting pressure and allow extraction of the viscous substance 4 from the container. The pressure sensitive opening may be created by sealing the end of the elongated housing 1 with just sufficient force to prevent the viscous substance 4 from leaking from the elongated housing 1 but will break the seal if a predetermined amount of pressure is applied to the pressure sensitive seal.
Figure 4 shows another embodiment of the container of figure 3 wherein the opening 3 is covered with a cover 5. The cover 5 will further seal the air chamber under the opening 3 to prevent contaminants from entering into the elongated housing 1 and results in a completely sealed elongated housing 1.
Figure 5 shows another 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 with one piston 3 located under each of the opening 3 thereby sealing the 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 as shown in figure 6. When the user squeezes either end of the elongated housing 1, the resulting pressure will urge the pistons 3 to slide away from their initial position toward the other 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 away from the opening 3 at the opposite end, 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.
Figure 7 shows another 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 a smaller dimension than the interior dimension of the elongated housing 1 and retained at their predetermined locations by a restrictor 7 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 predetermined position at the restrictor 7. Once the pistons 2 separate from the restrictor 7 they will allow free movement of the viscous substance 4 within the elongated housing 1. As shown in figure 8, depending on the orientation of the container, the viscous substance 4 may exit from either opening 3. Figure 9 shows another embodiment of the container of figure 7 wherein each of the two openings 3 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. Furthermore, the resulting sealed air chamber may be pressurized to a positive pressure or a negative pressure such that when one cover 5 is removed, the air pressure, whether positive or negative, in the remaining sealed air chamber will urge the pistons 2 to slide away from their initial position at the restrictors 7 and allow free movement of the viscous substance 4 within the elongated housing 1 and exit thought the opening 3 as shown in figure 10.
