FIELD OF THE INVENTION
The invention relates to an upright dispenser with a top elastic button, which can be attached to a container, bottle, pouch, bag or any other type of dispenser.
BACKGROUND OF THE INVENTION
Prior art dispensers dispense material unevenly because they lack a vent feature. This causes the material to flow unevenly (glugging). What is needed is an upright dispenser which has a vent feature which eliminates glugging.
BRIEF SUMMARY OF THE INVENTION
The inventive upright dispenser has an attachment end for attaching the dispenser to a container for holding material to be dispensed, the attachment end having a passageway which communicates with the container. The upright dispenser also has a dispensing tube, the dispensing tube having upper and lower through holes which connect to the attachment end passageway, the upper through holes providing a vent and the lower through hole providing a path for the material to be dispensed. The attachment end passageway has a sealing flange positioned below the upper and lower through holes in the dispensing tube. The attachment end has a top end with an elastic button, the elastic button being connected to a valve stem, the valve stem extending in the passageway and having a valve end which sealing engages with the sealing flange when the elastic button is in an undepressed position. When the elastic button is depressed, the valve end moves downwardly in the passageway to allow material to flow out of the container and through the lower through hole of the dispensing tube, when the container and upright dispenser are tipped sufficiently to allow gravity to cause the material to flow between the valve end and the sealing flange and out through the lower through hole of the dispensing tube, the upper through hole providing venting to eliminate glugging, and when the elastic button is released, it elastically returns to an undepressed position, pulling the valve end into sealing engagement with the sealing flange.

DETAILED DESCRIPTION OF THE INVENTION
While this invention may be embodied in many forms, there are described in detail herein specific embodiments of the invention. This description is an exemplification of the principles of the invention and is not intended to limit the invention to the particular embodiments illustrated.
For the purposes of this disclosure, like reference numerals in the figures shall refer to like features unless otherwise indicated.
Referring now to FIG. 1, a first embodiment of the inventive upright dispenser is shown generally at 10. The attachment end is shown at 12, which threadably engages with a container 14. The container has an opening 16 which is in fluid communication with an opening in the attachment end, shown at 18. A sealing flange is shown at 20 which sealingly engages with valve end 22. The valve has a valve stem 24 which is connected to an elastic button 26. A dispensing tube is shown generally at 28, and is divided into an upper section 30 and a lower section 32. Upper section 30 provides venting, providing a path for air to communicate with the container when the valve end 22 is opened, while the lower section 32 provides a path for the fluid to be dispensed to flow when the container and dispenser are tipped sufficiently to allow gravity to cause the fluid to pour.
Referring now to FIG. 2, a cross section view of FIG. 1 is provided.
Referring now to FIG. 3A and 3B, a top view of the upright dispenser of FIG. 1 is provided.
Referring now to FIG. 4A and 4B, the upright dispenser can be provided with a tamper cap, shown at 34. Tamper cap 34 can be constructed and arranged to snap fit to the upright dispenser, to cover the elastic button 26. The upright dispenser can also be provided with a dispense foil seal which covers the end of the dispensing tube 28, shown at 36. Finally, the upright dispenser can be provided with a bottle seal, shown at 38.
Referring now to FIG. 5A and 5B, the upright dispenser is shown with the elastic button 26 half depressed and full depressed. When the elastic button is fully depressed (i.e. open position) the air return path provided by the upper section 30 of tube 28 is shown by the red arrow. The fluid path through lower section 32 is shown with a blue arrow.
Referring now to FIG. 6A and 6B, another embodiment of the upright dispenser is shown which includes a lever arm 40, which is pivotally connected to the extension tube 28 at 42. The lever arm is shown in the normally closed position, with the elastic button 26 in the undepressed position.
Referring now to FIG. 7A and 7B, the lever arm 42 is shown half open (the elastic button is half depressed). The elastic button is depressed by the lever arm protrusion 44. The elastic button is shown fully depressed in FIG. 7, right side figure.
Referring now to FIG. 8A and 8B, another embodiment of the upright dispenser is shown, which includes an flexible extension tube 45 for reaching hard to reach locations. The extension tube is shown in the open (right figure) and closed position (left figure). The extension tube includes a tube plug 46, which the end of the extension tube can plug into to store the extension tube when not in use (left figure).
Referring now to FIG. 9, the extension tube frictionally engages with dispensing tube 28. In this figure, the elastic button is half depressed, partially opening the dispenser.
Referring now to FIG. 10, the elastic button is shown fully depressed (open position).
Referring now to FIG. 11A and 11B, another embodiment is shown in which both a lever arm 40 and an extension tube 45 are provided.
Referring now to FIG. 12, the dispenser is shown in the normally closed position, with both the lever arm in the closed position (elastic button undepressed) and the extension tube bent and connected to the tube plug.
Referring now to FIG. 13, the dispenser of FIG. 12 is shown with the extension tube in the open position and the lever arm half depressing elastic button 26.
Referring now to FIG. 14, the elastic button is shown in the fully depressed, open position.
All of the parts of the invention are made out of various types of plastic. For example, FIG. 15 shows that the dispenser body, lever arm, valve, tamper cap and tube plug can be made out of polypropylene (PP), or high density polyethylene (HDPE). FIG. 16 shows that the elastic button(s) can be made from thermoplastic elastomer (TPE) or thermoplastic polyurethane (TPU), while the extension tube can be made of polypropylene (PP), high density polyethylene (HDPE), low density polyethylene (LDPE), thermoplastic elastomer (TPE), thermoplastic polyurethane (TPU), rubber, silicone and urethane.
