Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The invention relates to toilet plungers and, more particularly, to a storage device for toilet plungers that is effective, inexpensive, and attractive.




2. Description of the Prior Art




It is known to provide various types of containers, covers, or holders for toilet plungers. For example, the patent to Kent, U.S. Pat. No. 6,038,709, discloses a toilet plunger holder and cover that includes a generally cylindrical receptacle within which the elastomeric suction head portion of the plunger is disposed. A generally flat cover is adapted to be connected to the receptacle. The cover includes an elongate cylindrical portion that is adapted to be fitted about the handle of the plunger when the cover is connected to the receptacle. Other representative devices are disclosed in various patents, including those to Rehmann, U.S. Pat. No. 5,040,679; Kurzawa, U.S. Pat. No. 5,456,356; Sander, U.S. Des. 368,820; Zawalsky, U.S. Des. 383,935; Borger, et al., U.S. Pat. No. 5,836,322; Zawalsky, U.S. Des. 404,951; and Moore, U.S. Pat. No. 5,927,492.




Although the foregoing devices provide a technique to store a toilet plunger in a covered manner, certain problems have not been addressed. One of these problems is that the various prior art receptacles and covers (if provided) are not particularly attractive. Another problem is that the user cannot readily carry or manipulate the receptacles and/or covers. Another problem is that the devices are not particularly stable, such that they can be tipped over easily and cause any disinfectant or cleaning solution contained in the receptacle to be spilled. An additional problem is that the covers are not childproof. Yet another problem is that the devices are more expensive than desired, in part due to increased manufacturing expenses arising from the unusual or complex shapes of the devices. Desirably, a toilet plunger holder would be available that would be attractive, easy to carry and manipulate, tip-resistant, childproof, and easy and inexpensive to manufacture.




SUMMARY OF THE INVENTION




In response to the foregoing concerns, the present invention provides a new and improved toilet plunger storage device. The present invention has a fluid-impervious receptacle to receive an elastomeric suction head portion of a toilet plunger. The receptacle includes a conical side wall from which a straight-sided cylindrical portion projects upwardly. The upper end of the cylindrical portion is configured to receive a cover in locking relationship. A handle extends from the side of the receptacle.




The invention includes a cover. The cover has a generally conical member at its lower end and an elongate, hollow tapered tube that projects from the upper end of the conical member. The lower end of the conical member is configured to engage the upper end of the receptacle in locking relationship. In the preferred embodiment, the locking relationship between the cover and the receptacle is made by a bayonet-type connection in which projecting lugs from one of the members engage right-angled grooves included as part of the other member. An elliptical handle is disposed at the upper end of the tube.




If the receptacle and the cover are manufactured to suitable tolerances, a seal will be established between the receptacle and the cover that will minimize or prevent the escape of liquids of gases. Although it is not believed to be necessary, it would be possible to improve the seal between the receptacle and the cover by including a gasket as part of either or both of the receptacle or the cover.




The entire device can be formed integrally in a single, inexpensive molding operation. Preferably, the device is blow-molded by using a conventional plastics material such as high density polypropylene or polyethylene. The plastics material can be provided with various additives such as dyes. Upon being removed from the mold, a single circumferential cut can be made to separate the molded part into a cover and a receptacle. After any undesired flashing has been removed, the device is ready for service.




The receptacle has a wide base, and thereby will resist being tipped over. Because the receptacle is hollow and is made in an integral manner, it is fluid-tight and can be filled with disinfectant. The assembled device can be carried easily from place to place due to the elliptical handle at the top of the cover. The receptacle can be emptied out and cleaned readily due to the handle that is included as part of the receptacle. The engagement between the receptacle and the cover provides a seal that prevents odors and fluids from escaping. Because the cover and the receptacle are locked together by the bayonet connection, the device is childproof. Due to the particular shape of the device and because it can be molded from a variety of plastics materials in a variety of colors, the device is attractive to consumers. Because the device can be made from a plastics material in a molding operation, it is quite inexpensive.











The foregoing and other features and advantages of the invention will be apparent from studying the specification and reviewing the accompanying drawings that illustrate the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring to

FIGS. 1-7

, a toilet plunger storage device according to the invention is indicated generally by the reference numeral


10


. The storage device


10


is intended to receive a conventional toilet plunger


12


(shown in dashed lines in

FIG. 3

) that has a hollow, flexible, elastomeric suction head portion


14


from which an elongate, cylindrical handle


16


extends.




The storage device


10


includes a receptacle


20


. The receptacle


20


has a bottom wall


22


, a conical, inwardly tapered side wall


24


, and a cylindrical extension


26


that extends upwardly from the upper end of the side wall


24


. The bottom wall


22


is flat. The extension


26


is provided with three right-angled grooves


28


at its open end. Each of the grooves


28


has a vertical portion


32


and a horizontal portion


34


. The vertical portions


32


are spaced 120 degrees from each other. The horizontal portions


34


are rounded at their ends. The spaces between adjacent grooves


28


are occupied by horizontally extending relief portions


36


. The relief portions


36


provide a balanced look to the extension


26


, and also strengthen the extension


26


.




A hollow handle


38


is integrally formed as part of the receptacle


20


. The upper end of the handle


38


is connected to the extension


26


near the intersection with the side wall


24


. The lower end of the handle


38


is connected to the lower end of the side wall


24


.




The receptacle


20


is hollow in order to receive the elastomeric suction head portion


14


of the plunger


12


. The receptacle


20


can be filled with a disinfectant, cleaning or deodorizing fluid in which the head portion


14


can be immersed for storage.




The storage device


10


includes a cover


40


. The cover


40


has a generally conical portion


42


. An elongate, tapered hollow tube


44


projects from the upper end of the conical portion


42


and is joined thereto by a smoothly contoured portion


46


. The upper end of the tube


44


is provided with an elliptical, hollow handle


48


that is formed integrally with the tube


44


. The handle


48


is configured to receive the fingers of the user's hand. A small side wall


50


extends vertically downwardly from the lower edge of the conical portion


42


. A ledge


52


extends radially inwardly from the bottom end of the side wall


50


. A cylindrical sleeve


54


extends vertically downwardly from the inner edge of the ledge


52


. Three cylindrical lugs


56


project radially outwardly from the sleeve


54


. The lugs


56


are spaced 120 degrees from each other. It is intended that the diameter of the sleeve


54


will be such as to enable it to fit within the cylindrical extension


26


in a telescoping manner.




The device


20


can be formed integrally in a single, inexpensive blow-molding operation from a plastics material such as high density polyethylene, polypropylene, or other suitable material. The material can be provided with various additives such as dyes in order to make the device any desired color. The plastics material is liquified, either before or after being placed in the mold, and then is distributed uniformly on the inner surface of the mold by the application of pressure. The mold is shaped so that the part line of the mold runs through a plane that bisects the handles


38


,


48


. After the now-solidified plastics material is removed from the mold, the receptacle


20


and the cover


40


are separated from each other by making a circumferential cut between the upper end of the extension


26


and the lower end of the sleeve


54


. After removing any flashing, the device


10


is ready for service. The general technique of blow-molding articles made of plastics materials such as polyethylene is known to those skilled in the art, and therefore does not need to be described in further detail here.




Typical dimensions for the receptacle


20


are about 8.375 inches for the largest diameter (which occurs near the intersection of the bottom wall


22


and the side wall


24


), about 6.5 inches for the inner diameter of the extension


26


, about 5.0 inches from the bottom wall


22


to the top of the extension


26


, and about 1.75 inches for the height of the extension


26


. The grooves


28


are about 0.5 inch in width. Typical dimensions for the cover


40


are about 22.5 inches for the distance between the top of the handle


48


to the bottom of the sleeve


54


, about 6.375 inches for the outer diameter of the sleeve


54


, about 8.125 inches for the diameter of the side wall


50


, and about 0.5 inch for the diameter of the lugs


56


. The tube


44


tapers linearly from a diameter of about 2.375 inches at the intersection with the contoured portion


46


to a diameter of about 1.375 inches near the handle


48


. The wall thickness of the receptacle


20


and the cover


40


is about 0.09 inch, although some variation in wall thickness is expected and generally is not harmful.




If the device


10


is manufactured to close tolerances, there is no need for a gasket at the intersection between the receptacle


20


and the cover


40


. However, it would be possible, if desired, to provide a gasket or other type of seal for the upper end of the extension


26


, for the sleeve


54


at the intersection with the ledge


52


, or both.




It will be appreciated from the foregoing description that the invention provides significant advantages over prior devices. Because the bottom wall


22


of the receptacle


20


has a large diameter, the device


10


will resist being tipped over. Because the receptacle


20


is hollow and is made in an integral manner from a plastics material, it is fluid-tight and can be filled with disinfectant, cleaning, or deodorizing fluid. The device


10


can be moved easily by grasping the handle


48


, and the receptacle


20


can be emptied out and cleaned readily by grasping the handle


38


. The interaction of the lugs


56


and the grooves


28


, particularly the rounded ends of the horizontal portions


34


, established a bayonet-type connection that causes the cover


40


and the receptacle to be locked to each other so as to render the device childproof. The tight fit between the cover


40


and the receptacle


20


prevents odors and fluid from escaping. Due to the particular shape of the device


10


and because the device


10


can be molded from a variety of plastics materials in a variety of colors, the device


10


is attractive to consumers. Also, because the device


10


can be made from a plastics material in a molding operation, it is quite inexpensive to manufacture.




Although the invention has been disclosed in its preferred embodiment, it will be apparent to those skilled in the art that various changes and modifications can be made thereto without departing from the true spirit and scope of the invention as hereinafter claimed. Merely by way of example and not by way of limitation, it is possible to interchange the grooves


28


and the lugs


56


, that is, the grooves


28


could be included as part of the cover


40


and the lugs


56


could be included as part of the receptacle


20


. It is intended that the patent shall cover, by suitable expression in the appended claims, all such changes and modifications.
