Abstract

A dispenser having an outer flanged edge for gripping the edge of a container and a wall for covering the top of the container. The space between the wall and the top of the container is divided into two chambers. One of the chambers is covered by a resilient, depressible protruberance and the other chamber is covered by a portion of the wall containing a spout. Openings between the chamers permit flow of fluid to the spout for dispensing the fluid.

The most common methodEof packaging oil and similar fluids is in quart cans and in the past it has been the practice to either use all of the oil in the can at the time the can is opened or pour the oil into a special dispensing container such as the spouted oil can or an oil can with a pump for applying the lubricant. Many times there is a greater quantity of oil in the container than is needed, either for filling another container or applying to apparatus which needs lubricating and as a result oil is left in the container in an exposed condition where dirt and other contaminating material can drop through the hole in the top of the can.

In the past, special caps with pumps built in have been proposed for converting an oil can into an oil dispenser; however, these devices have necessitated elaborate pumping elements including tubular stems for insertion into the can, resulting in constructions which have been either too costly or complicated for general usage by the public.

With the foregoing in mind, it is the principal object of this invention to provide a fluid dispensing cover in which the space under the cover is divided into separate chambers with the chambers connected for flow of fluid therebetween.

Another object of the invention is to provide for supporting the wall of the cover with a downwardly extending rib having projections to provide the openings for passage of fluid between the chambers.

A further object of the invention is to provide an annular discharge portion andchamber surrounding the central depressible portion of the wall.

A still further object is to provide a cover of resilient material which may be depressed and will tend to return to the extended position upon release.

A still further object is to provide a construction in which the spout may be attached and removed with ease for easy handling andpackaging.

Another object is to provide a spacing member with openings spaced for greater support where needed and lesser support and greater flow of fluid where the support is not needed.

These and other objects of the present invention may be achieved by positioning the spacing members between the discharge and compression chambers to provide wall support and flow of fluid between chambers.

To the accomplishment of the foregoing and related ends, the invention, thenjcomprises the features hereinafter fully described and particularly pointed out in the claims, the following description and the annexed drawings setting forth in detail a certain illustrative embodiment of the invention and'a modification thereof, this being indicative, however, of but some of the various ways in which the principles of the invention may be employed.

In the annexed drawings:

FIG. 1 is a front elevational view of a container with the fluid dispensing cover ofthe invention mounted thereon.

FIG. 2 is an enlarged sectional view taken along the plane of line 2--2 of FIG. 1, parts being broken away and with the spout closure plug in the detached position.

FIG. 3 is a plan view of the cover shown in FIG. 2 showing the underside of the cover.

Referring to FIGS. 1 and 2, a fluid dispensing cover 1 embodying the invention is shown mounted on a container such as cylindrical can 2 which may be of metal. The can 2 is of a type normally used for oil and other fluids and has a substantially flat top 3 and a flange 4 where the top joins the side of the can. The cover 1 has a wall 5 with a generally circular shape to conform to the shape of the can 2 and a downwardly extending flanged edge 6 having an enlarged bead 7 for mounting over the flange 4 of the can in sealing engagement.

The wall 5 has a depressible portion in the form of a hemispherical protruding center 8 which may be depressed from the hemispherical shape, shown in solid lines, to the concave position, shown in chain-dotted lines in FIG. 2. Surrounding the center 8 and adjacent the edge 6 of the wall 5 is an annular discharge portion or rim 9 extending inwardly a spaced-apart distance from the edge and having an outlet such as nipple 13 extending upwardly for receiving a snap-on spout 14 over the end of the nipple for conveying fluid from the nipple to a desired point of application.

The wall 5 is held in spaced-apart relationship from the top 3 of the can 2 by a spacing member or rib 15 extending downwardly from the wall at the area of the wall between the rim 9 and center 8. Passage of fluid through the rib 15 is facilitated by downwardly extending projections such as lugs 16 in spaced-apart positions along the edge of the rib providing openings 17. The space between the wall 5 and the top 3 is divided by the rib 15 into a discharge chamber 18 and a compression chamber 19 with the openings 17 connecting the chambers for passage of fluid therebetween.

The rib 15 is circular and surrounds the center 8 of the wall 5 providing a stiffening member for resisting the spreading movement and forces generated upon depression of the center. It is important the depression of the center 8 does not cause the rim 9 to tilt and thereby deflect the spout 14 making it difficult to control the flow of fluid from the spout to the desired point of application. As shown in FIG. 3, the lugs 16 are spaced apart around the edge of the rib 15 with the lugs adjacent the nipple 13 and spout 14 being located at closely spaced-apart positions providing additional reinforcement and support for the rim 9 to further resist tilting of the rim upon depression of the center 8.

The cover 1 is preferably molded of a resilient plastic material such a polystyrene with the edge 6 having sufficient resiliency to snap over the flange 4 of a can 2 and retain the cover on the can in fluid sealing relationship. The center 8 of the cover 1 is preferably ofa resilient material which may be of the same material as the remainder of the cover and have the property of being depressible to the position shown in chain-dotted lines and returnable to the position shown in full lines in FIG. 2. The spout 14 may also be molded of a plastic material such as vinyl and have resilience to stretch over the nipple 13.

As shown in FIGS. 1 and 2, a plug 25 may be provided for closing the opening in the spout l4 and may be molded with the cover 1 so as to have a connecting cord or filament 26 from the edge 6 of the cover to the plug.

Installation of the cover 1 involves snapping the edge 6 and bead 7 over the flange 4 of the can after an opening 23 is made in the top 3 of the can. The opening 23 in the top 3 may be located, as shown in FIG. 2, directly adjacent the nipple l3 and spout 14; however, the opening may be spaced from the spout and there also may be more than one opening in the top of the can if desired. After the cover 1 is snapped over the can 2, the spout 14 may be applied over the nipple l3 and the plug 25 inserted in the open end of the spout. This will protect the fluid 24 in the can from contamination.

When it is desired to apply the fluid 24 from the can 2 to a point of application, the plug 25 is removed, the can is tilted causing fluid to enter the discharge chamber 18 and fill the spout 14. The control of the flow of fluid 24 from the spout 14 is obtained by depressing the center 8 of the wall to increase the flow of fluid from the spout and permitting the center to resiliently resume the hemispherical shape to stop the flow of fluid from the spout. In this manner, it is possible to obtain precise control of the flow of fluid 24 from the can 2 and at the same time protect the contents and fluid of the can from contamination during periods when the can is not being used. While a certain representative embodiment and details have been shown for the purpose of illustrating the invention, it will be apparent to those skilled in the art that other changes and modifications may be made therein without departing from the spirit or scope of the invention.
