ABSTRACT:
FIELD OF THE INVENTION
This invention relates to closures and containers and particularly to the dispensing of liquids such as petroleum oil from a container.
BACKGROUND OF THE INVENTION
Many products such as motor oil, solvents, soap and like products are bottled or packaged in plastic containers having a neck offset to one side of the main body of the container and closed by a screw type closure. Such closures require the total removal of the threaded cap, which exposes the contents of the container to the atmosphere. When attempts are made to pour or empty the contents of the container into another receptacle, spillage typically occurs. Particularly in the case of oil for the crank cases of automotive engines, space usually does not permit the container of oil to be gradually tilted to obtain uniform flow. Also, once flow is obtained and the container is inverted it is difficult if not impossible to stop overflow problems, which cause spillage. Additionally, the design of such containers often is such that air equalization causes the contents to surge resulting in spillage. Also, once such containers are inverted, it is not possible to interrupt flow without spillage.
There is a need for improved container or container closure combination which eliminates the aforementioned problems with the pouring of liquid from one container into a receiving opening in a container or a fill pipe for the crank case of an automobile engine.
SUMMARY OF THE INVENTION
It is an object of the invention to provide an improved closure-container combination or a closure for use with a variety of threaded containers.
It is a further object of the invention to provide such package or closure, which allows for the pouring from plastic bottles without spillage.
Still another object of the invention is to provide such a package or closure which is drip free and which can accommodate different size liquid receiving ports without the need for separate funnels and the like.
Still another object of the invention is to provide an improved closure-container or closure, which allows the flow of liquid to be terminated anytime before the contents of the container are completely emptied and also permits regulation of the rate of flow from the container.
Another object of the invention is to provide a dispensing package or closure which can be placed in an inverted dispensing position relative to the receiving container but remains in a closed position after which it can be open to insure that all of the material is dispensed into the receiving container without drip or splash.
Yet another object of the invention is to provide a container-closure or closure for containers, which facilitates threading of a package in its closed condition relative to a receiving container, after which the closure can be opened to insure a transfer of materials from the container to the receiving container without escape of fumes or liquid.
The objects of the invention are attained by a container closure package, which includes a container having a body portion with a tubular neck, or pouring spout in which the end of the pouring spout is closed. Passage means in communication with the container are through passages in the side of the pouring spout, which in a closed position are closed by a tubular sleeve slidable on the exterior of the pouring spout, but initially fixed to the container to form a unitary structure through means of a frangible line of weakening. After fracture of the frangible connection the sleeve can be moved between open and closed positions to dispense material from the container.
In another embodiment of the invention the package is provided with external threads for threading into a receiving opening of another container so that materials can be transferred without the escape of fumes or liquid.
The objects of the invention are attained by a two-part closure structure in the form of a tubular spout and a sliding closure or sleeve. The closure structure is incorporated directly into the container finish or neck. In the case of a threaded closure a tubular body member is closed at one end and is threaded at its opposite end to receive matching threads on a container neck. The tubular body member is provided with radially extending openings from which the contents of the container can be emptied. The radially extending openings are closed by a slidable sleeve which in the closed position obstructs the radially extending passages and which can be slid downwardly on the tubular portion a predetermined amount to open the radially extending ports a selected amount to dispense liquid from the container. The sleeve is provided with a flange at one end, which extends radially outwardly from the axis of the tubular member and can be used to open and close the container. For example, opening can be accomplished by inverting the package and holding the flange stationary on an edge of an opening into a receiving receptacle. Subsequently, moving the container downwardly causes the sleeve to slide to an open position relative to the tubular body member to dispense the contents without dripping or splash.
In the case of the container, the tubular neck or finish of such containers can be closed and provided with radially opening dispensing ports adjacent to the closed top. The slidable sleeve on the tubular neck closes the radially extending ports and a flange on the bottom of the sleeve can be held stationary or can be moved to slide the sleeve on the spout and expose the ports.
