ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to the field of fluid containers and to a device to assist in neatly pouring the contents of the container. More particularly, the invention is concerned with a pouring spout which can be selectively opened and closed when attached to a container.
2. Description of the Prior Art
Many products are stored in containers and are dispensed for use by pouring them from their containers. By using a spout or funnel, a person can prevent spills. However, most funnels and spouts do not allow the user to stop the flow of fluid or selectively control the amount and rate of fluid being dispensed. There has thus developed a need for a pouring spout that allows the user to stop the flow of fluid or selectively control the amount of fluid being dispensed and yet still be simple and reliable to use and inexpensive to make.
SUMMARY OF THE INVENTION
The push-pull spout assembly broadly includes a pair of telescopically coupled cooperating first and second tubular members for dispensing fluids from a container to which the spout assembly has been connected. The first and second members cooperatively define a fluid passageway. The first member includes a coupler for connecting the spout assembly to the container. The first and second members include complemental closure walls projecting into the fluid passageway. The complemental walls are selectively positionable in a blocking position, in which they are horizontally aligned and block the flow of fluid through the passageway, and an offset position, in which the walls are shifted axially relative to one another and out of horizontal alignment to permit the flow of fluid through the passageway.
In preferred forms, the tubular members are circular in cross section and are each integrally formed from a synthetic resin. The complemental closure walls are semicircular in shape and are generally similar in size. The second member includes a pin and the first member includes a slot that receives the pin. The slot limits the travel of the pin, and thus the second member with respect to the first member, to one condition corresponding with the blocking position and a second condition corresponding to the offset, flow permitting position.
