The present invention relates to a funnel having multiple features and functions, and more particularly, an multipurpose vended funnel having an integrated self-venting system for use in filling reservoir and/or containers.
Conventional funnels are typically used to facilitate the pouring of liquids, powders, or any other filler material into reservoirs and/or containers that have multiple size opening. A funnel typically includes inverted hollow cones or tapering or cylindrical tubes having a wide opening at the top and a narrow spout opening designed to be fitted into the openings of associated receptacles into which material is to be poured.
Closed or sealed fluid systems such as the cooling and oil system of a motor vehicle include a fill port or nozzle through which fluids are introduced or added. Similarly containers, such as bottles include an opening through which the fluid or solid material is introduced to fill the container. It is common practice to use a funnel inserted into the container opening or system port/nozzle to fill or add the material to these containers or sealed systems.
Funnels are often used in the filling process of liquids, powder and/or filler material into household containers. Funnels are commonly known and used to prevent spilling in pouring liquids into containers with small openings. A household funnel may include a small tapering tube with a wide, cone-shaped mouth; however, this common design often causes liquid to bottleneck and backup therein.
In food dispensing establishments, such as restaurants, cafeterias, luncheonettes, and coffee shops may have problems in the use of relatively viscous liquid condiments, such as ketchup, mustard and the like. These problems arise from the fact that conventional packaging for these condiments are done in clear glass bottles having a relatively narrow neck. In view of the forgoing aspects, traditional funnels are undesirable for many reasons. Specifically, when liquid backs up in the funnel it causes difficulty arises from the fact that the surface tension of the relatively viscous fluid is such as to preclude facility of flow through the neck of the bottle, thus making it necessary to shake the bottle vigorously, often with disastrous results.
For most prior art funnels, venting is accomplished in one of two ways. In one case, the venting is accomplished primarily through the fill hole in the funnel. That is, the funnel's fill hole is used to add material to the container/system as well as to vent the air. Depending upon the sealing ability of the funnel to the opening/nozzle some venting also may occur in the space between the funnel and the inside surface of the opening port or nozzle. Alternatively, the funnel is held so it does not contact the nozzle or opening while adding the material. This leaves a space between the funnel and the inside surface of the opening port or nozzle in which the funnel is inserted. The air from the container system vents through this space.
In view of the above descriptions, traditional funnels are undesirable for many reasons. Specifically, when liquid backs up in the funnel it causes unwanted spillage due once the air traps inside the reservoir or container. It is also known to provide funnels in sets of different sizes for different applications. However, heretofore, such sets of different-sized funnels have not been characterized by designs which facilitate compact, nested storage. It is also known to provide funnels with handles to facilitate grasping in use. However, heretofore, such handles have tended to impair the nesting of sets of funnels and have either been relatively large or have been difficult to grasp, securely, particularly for people with impaired grasping ability.
The primary object of the present invention is to provide a multipurpose vented funnel with a self-contained venting system which is designed to rapidly vent air or gas in a safe manner from a container being filled without being splashed or without spilling liquid.
In order to achieve this aspect, the present invention includes a passage way within the funnel conical member and handles structure between the inner and outer walls of the said invention. The passage way is preferably elongated and substantially rectangular in shape.
The present invention includes an funnel portion for receiving liquid, vented rectangular handle for preventing liquid backup in the funnel portion and an outlet spout with an end for delivery liquid therefrom.
The present invention may further include within the funnel inner sidewall, conical grooves to prevent the spatters and blockage, extending linearly and generally vertically from the top of the funnel to the top of the down spout.
In yet another aspect of the invention, the downspout of the funnel having stabilizes tabs outwardly project from the tubular spout for stably supporting the funnel in a generally upright orientation when positioned within an opening of a receiving container.
The present invention solves the problems of conventional funnel by improving standard funnel and providing a multipurpose vented funnel that accommodates various functions within the household, auto, restaurants, while incorporating different sizes and a means for the air to escape out of a container for which a funnel is being used.
