| CLAIMS 1. A valve for use with a standard tube dispenser for a flowable compound such as caulk, silicone and the like, the tube being of the type having a movable bottom section arranged to be pressed upward by a lever-actuated dispensing gun, the valve comprising a cylindrical body having a lower female threaded section having threads adapted to receive a standard, male threaded tip of a standard tube dispenser, an upper male threaded portion having the same thread dimensions as the tube tip, and a stop valve portion, the stop valve portion comprising a rotatable cylindrical member having a passage, the cylindrical member being arranged laterally to the longitudinal axis of the cylindrical body, the stop valve portion being further connected to a handle portion for rotating the stop valve portion. 2. A valve for use with a standard tube dispenser for a flowable compound such as caulk, silicone and the like, the tube being of the type having a movable bottom section arranged to be pressed upward by a lever-actuated dispensing gun, the valve comprising a cylindrical body having a lower female threaded section having threads adapted to receive a standard, male threaded tip of a standard tube dispenser, an upper male threaded portion having the same thread dimensions as the tube tip, and a stop valve portion, the stop valve portion comprising a laterally displacable member having a passage, the laterally displaceable member being arranged laterally to the longitudinal axis of the cylindrical body. |
Field of the invention The present invention relates to caulking tubes.
Background
One of the problems with known caulking tubes is that after the pressure on the tubes is released the caulk continues to flow out of the tube, thereby "dripping" and causing a mess. The current solution to prevent this "dripping" is a pressure release button on the sealant gun. This does not work well, however. Even after the release button is pressed, the caulk will still keep on dripping, (it is understood that term "caulking tube" also encompasses silicone tubes and the like). Summary of the invention
The invention provides an ANTI DRIP VALVE to be mounted on the top of the tube. The valve can be mounted on any existing tube with a loose nozzle. This will enable the user to stop the flow of caulk passing thru the nozzle and prevent "dripping". According to one aspect the invention provides a valve for use with a standard tube dispenser for a flowable compound such as caulk, silicone and the like, the tube being of the type having a movable bottom section arranged to be pressed upward by a lever-actuated dispensing gun. The valve comprises a cylindrical body having a lower female threaded section having threads adapted to receive a standard, male threaded tip of a standard tube dispenser. The cylindrical body further comprises an upper male threaded portion having the same thread dimensions as the tube tip, and a stop valve portion. The stop valve portion comprises a rotatable cylindrical member having a passage, and is arranged laterally to the longitudinal axis of the cylindrical body. The stop valve portion has portion for rotating the stop valve portion. Brief description of the drawings

Fig.2 shows a perspective of the open valve ready for the caulk to pas thru.
Fig.3 shows a perspective of the closed valve in a position for stopping the flow of the caulk.
Detailed description of the invention
The valve is to be made in such a way that it will fit all existing standard caulk tubes with a loose nozzle. As shown in fig. 1, the valve is screwed on top of any existing standard caulk tube. After this the loose nozzle is screwed on top on the valve. This will provide a system which will enable the user to control the caulk flow. The user can also control the amount of caulk passing thru the valve by simply reduce the opening of the valve just by turning the valve slightly. As shown in the figures, the valve comprises a handle connected to a cylindrical member having a passage. By rotating the handle, the passage will selectively allow or prevent the flow of the caulking material.
Alternate embodiments According to another aspect of the invention, the valve can also be closed by simply press the valve button instead of turning the valve button in order to stop the flow of caulk. In this embodiment, the passage is laterally displaced to stop the flow of the material.
