This invention pertains to container pour spouts. More particularly it relates to an internally mounted expandable contractible pour spout insert for containers with pour openings for motor oils, transmission fluids, cooking oils, liquids, liquors, etc.
A variety of pour spouts and funnels for pouring liquids from containers are known. Lukenbill, U.S. Pat. No. 1,804,627 issued May 12, 1931 discloses a sanitary pouring cap with accordion extending and retracting pour spout. Borah, U.S. Pat. No. 3,093,273 issued Jun. 11, 1963 discloses a retractable and extendable container spout. Nagy, U.S. Pat. No. 4,817,832 issued Apr. 4, 1989 discloses a telescoping nozzle assembly adapted to be secure to the opening of container to facilitate pouring of container fluid. Johnston Wills, Pub. No. US 2004/0188474 published Sep. 30, 2004 discloses a collapsible/flexible pouring attachment to pour liquid from a plastic bottle and/or container. Borah, U.S. Pat. No. 2,804,242 issued Aug. 27, 1957 discloses a container spout and gasket combination. Rigel, U.S. Pat. No. 8,430,279 issued Apr. 30, 2013 discloses a bottle accessory for application with a cap to the neck of a bottle, particularly useful for attaching a retractable spout to a bottle.
Cited for general interest is Black, U.S. Pat. No. 4,256,154 issued Mar. 17, 1981 disclosing a bottle with retractable funnel top.
Other devices are secured to the opening of a liquid container to assist in pouring therefore. Motor oil and transmission fluid pour spouts typically have a fixed or flexible hose with mounting adapted to screw onto the exterior threads of an opened container. Cooking oils have a spout with mountings adapted to insert into the opening of a container opening. Funnels come in a variety of shapes and designs to contain and direct fluids into a desired bottle or container.
Most of these pour spouts and funnels are combination cap/pour spouts that are difficult to construct, produce, or to secure to the opening of a liquid container. Other separate pour spout and funnel devices are required to be applied after a fluid container is opened.
There thus remains a need for an improved pour spout insert with a flexible accordion spout removably affixed to a container opening to eliminate the need for finding a funnel or other spouts to aid in pouring. The apparatus described below provides such an invention.
The present invention comprises an expandable contractible pour spout cap insert adapted to removably secure to openings of fluid containers. It comprises a pull cap with a finger pull ring and a threaded pull cap base attached to a flexible telescoping accordion pour spout with a first threaded end adapted to removably secure to the threaded pull cap base, and a second end with side walls defining a channel, when mounted in communication with fluid container openings. The pull cap base is removably secured to the threaded first end of the accordion pour spout to close its channel in a storage mode. The pull cap base is then removed after the pull cap extends and unblocks the pour spout channel for pouring in a pouring mode.
A flexible extension/inversion plastic diaphragm with a top is affixed to the second end of the telescoping accordion pour spout with a bottom structured, when secured, to seal to openings of a fluid container. The plastic diaphragm is structured to extend beyond the opening of the fluid container to expose the telescoping pour spout for pouring in an extended mode. The telescoping pour spout is then collapsed against the inverted plastic diaphragm to store therein. The collapsed pour spout within the inverted plastic diaphragm fits within an opening of a fluid container in a storage mode.
A pour spout cap base structured as a threaded nut fitting with an opening structured to surround and secure the bottom of the extension/inversion plastic diaphragm secures the plastic diaphragm and pour spout to removably seal to threaded openings of fluid containers to align with the channel of the pour spout cap cartridge insert.
The bottom of the plastic diaphragm is structured as a flanged gasket to secure about the opening of the fluid container to seal as a compression fitting when the pull cap threaded base is screwed onto the container threaded opening to prevent spills. The pour spout cap cartridge insert threaded nut fitting opening has internal threads to secure to corresponding threaded external openings of fluid containers in one embodiment.
In another embodiment, the pour spout cap base threaded nut fitting could have external threads to secure to corresponding threaded internal openings of fluid containers.
For pouring, the pull cap is pulled and removed from its pour spout cap base extending the pour spout. The pull cap is then removed from the accordion pour spout first end for pouring in a pouring mode. After pouring, the pull cap is replaced back onto the first end of the telescoping according pour spout to close the same for storing liquids in the fluid container in a storage mode. The telescoping accordion pour spout may or may not be compressed and secured back into the pour spout plastic diaphragm and its pour spout cap base for storage depending upon the preference of a user.
The pour spout cap base is structured to affix to and form a seal with openings of fluid containers. The pour spout cap base usually is threaded internally to secure to corresponding threads of the opening of the fluid container.
The pull cap may be structured to collapse into place on the pour spout cap base when not in use. It is then extended when the pour spout is to be used. To aid in its removal, the pull cap may include a retractable finger pull ring.
In one variation, the bottom of the flexible extension/inversion plastic diaphragm is structured as a flanged gasket to secure about the opening of the fluid container when the pull cap threaded base is screwed onto the container threaded opening.
The pour spout bottom, telescoping accordion pour spout and extension/inversion plastic diaphragm may be constructed as one piece with the fluid container. This embodiment has the pour spout cap then threadably attached to the end of the pour spout opening to removably seal the same.
The expandable contractible pour spout cap insert is a separate cartridge insert structured to fit and secure to the opening of the neck of a fluid container forming a fluid tight seal in communication with the interior of the fluid container neck when secured therein as described above.
In one embodiment, the cartridge insert is constructed of a universal size to fit various sized containers having standard threaded neck openings. Other cartridge insert configurations snap fit to the container neck openings with fluid type joints wherein the cartridge insert secures within or without the container pour opening to form fluid sealed joints.
The flex hose accordion tubing is expandable and collapsible made of a corrugated thin plastic. The corrugated shaped allows it to bend in a desired direction when extended for pouring. It then collapses back into the cartridge insert for storage.
The invention thus provides a simple cost effective pour spout cartridge that can be manufactured in different sizes to adapt to most containers to provide a container with a built in pour spout. This eliminates the need for funnels and additional attachable spouts, which are more expensive. It provides a container with a flexible plastic spout that sits inside the cartridge with a pull top cap that is disposable or reusable.
The pour spout cap 10 is unscrewed from the threaded end 14 of the flexible accordion hose 16 for pouring fluids from the container. After pouring, the pour spout cap 10 is screwed back on to store remaining fluids in the container.
The present invention may be embodied in other specific forms without departing from its structures, methods, or other essential characteristics as broadly described herein and claimed hereinafter. The described embodiments are to be considered in all respects only as illustrative, and not restrictive.
The scope of the invention is, therefore, indicated by the appended claims, rather than by the foregoing description. All changes that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
