Abstract:
There is shown and described a bottle having an integral, retractable funnel at the top or opening thereof. The retractable funnel is disposed within the bottle in normal operation but is extended from the bottle opening during a refill operation.

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention is directed to refillable bottles, in general, and to such bottles having integrally formed funnels associated with the openings thereof, in particular. 
     2. Prior Art 
     There are many known consumer utilizations of bottles which are refillable from other sources. For example, many cleaning solutions come in large containers for easy handling and storage. Smaller containers, e.g. bottles, are used in the every day use or application of the materials. For example, window cleaner or spray in the form of a liquid is stored in large containers having a size of a gallon or more. The ordinary applicator may contain a half pint or the like wherein the container is relatively easily handled by the user. Therefore, a large supply source is maintained for supplying the useful product but the actual applicator is maintained small for ready utilization. 
     When the applicator device is emptied, it is refilled from the storage container. However, in most cases the applicator bottle has a relatively small opening and/or neck at the top thereof. On the other hand, the storage container may have a much larger opening. Even if the storage container has an opening of substantially the same size and configuration as the applicator bottle opening, a significant chance of spillage occurs. In point of fact, spillage frequently occurs even though significant care and dexterity are exercised by the user. In the alternative, a funnel may be utilized in the refill operation. However, this has the disadvantage of requiring that a funnel be obtained or that the funnel have the appropriate size and configuration to accomodate both the refillable applicator bottle and the refill source container. The usual difficulties and problems which are encountered are well known to those in the art. In addition, where caustic chemicals are to be refilled, care must be given to thorough cleaning of the funnel prior to use.

     SUMMARY OF THE INVENTION 
     The invention shown and described herein comprises a bottle or other container having a neck portion which is adapted to receive a cap or other suitable closure element. A funnel made of flexible material is integrally formed with and connected to the neck portion. The funnel is normally arranged to be inserted within the container and inside the neck portion thereof. A pull-tab is attached to the surface of the funnel and within the container. The funnel may be selectively withdrawn from the container by pulling on the pull-tab. Conversely, the funnel can be reinserted into and stored within the container merely by pushing the funnel into the container. 
    
    
     BRIEF DESCRIPTION OF THE DRAWINGS 
     FIG. 1 is a cross-sectional view of the opening of a container having an integrally formed, retractable funnel associated therewith and stored therein. 
     FIG. 2 is a cross-sectional view of the same with the retractable funnel partially removed. 
     FIG. 3 is a cross-sectional view of the same with the funnel completely extended and ready for refill. 
    
    
     In the several figures, similar components bear similar reference numerals. 
     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring now to FIG. 1, there is shown a schematic representation of the top of a bottle or other suitable container 10. The container 10, as shown, represents the upper or top portion thereof. A neck 11 of suitable configuration is formed as a portion of the bottle in a standard fashion. In this embodiment, neck 11 includes the helically arranged ridges 12 which are used to effect a screw arrangement for the container 10. The screw top arrangement is such that a cap, spray device or the like can be screwed onto container 10 and affixed thereto for the appropriate purpose such as sealing the bottle, applying a spray mechanism or the like. An integral funnel 13 is provided in the container. The funnel may comprise a relatively thin, resiliently deformable, web-like member. As shown in FIG. 1, funnel 13 tends to expand at the free end thereof which, in this case, is stored internally of container 10. Funnel 13 is joined to the upper end of neck 12 at the outer edge 15 which abuts the appropriate attachment or cap applied thereto. Funnel 13 is integrally formed with the outer edge of neck 11 of container 10. 
     A pull-tab 14 is joined to the inner surface of funnel 13. In particular, the pull-tab, as shown in this embodiment, is somewhat elongated and extends a substantial distance into container 10 and is attached to the surface of funnel 13. In addition, the free end of pull-tab 14 is shown bent over and conformed to the outer edge or lip of neck 11. In some other embodiments, it may be desirable to have this free end arranged to fall within a suitable groove or aperture in lip 15 so that the screw down apparatus will meet appropriately with a uniplanar edge 15. Alternatively, the pull-tab 14 can terminate within the opening of funnel 13 or not depending upon the arrangements made between the bottle and screw-on apparatus. 
     Appropriate ribs 13A can be formed in funnel 13 to cause the funnel to inherently expand at the free end thereof. In addition, other strengthening configurations can be applied to the funnel. Conversely, ribs 13A can be eliminated and suitable folds or the like can be provided in funnel 13 to facilitate the folding, retractability and expandability of the funnel. 
     Referring now to FIG. 2, it is seen that funnel 13 comprises a relatively thin membrane or web-like material which is partially withdrawn from container 10 at the neck 11 thereof. This withdrawal is, typically, effected by pulling on pull-tab 14 which is fastened to or integrally formed with funnel 13. In the embodiment shown in FIG. 2, a groove or aperture 16 is provided to receive and seat the free end portion of pull-tab 14. 
     Referring now to FIG. 3, there is shown a cross-sectional view of the container with funnel 13 fully extended and ready for operation. It is seen that the interior end of funnel 13 is joined to and, preferably, formed integrally with the outer edge or surface of neck 11. This permits the funnel to be readily accessible at all times and also prevents any spillage between the funnel and container 10. The relative relationship of pull-tab 14 to funnel 13 is readily discernible in this view also. 
     After container 10 has been refilled from a supply source via funnel 13, funnel 13 is then returned to the position shown in FIG. 1 by merely pushing funnel 13 back into container 10 via neck 11. 
     While not so limited it is expected that the container and the integrally formed funnel will be fabricated of a plastic material. In particular, the funnel will be fabricated of a flexible plastic material. The integral container/funnel device can be fabricated by suitable blowmolding techniques which are known in the art. 
     Thus, there has been shown and described a preferred embodiment of the instant invention. The description and illustrations depict a preferred arrangement of the container and funnel formed as an integral unit. It is clear to those skilled in the art that various modifications can be made to the particular configuration of the funnel, the pull-tab and/or the container configuration. However, any such modifications which fall within the purview of the instant description are intended to be included therein as well. That is, the description is intended to be illustrative only and is not intended to be limitative of the invention. Rather, the scope of the invention is limited only by the claims appended hereto.
