One of the most difficult chores in the bathroom is cleaning the toilet bowl. Traditional methods of bowl cleaning utilize two common objects, first a container of cleaner in either a liquid or granular form and second a scrub brush. The cleaning method involves introducing the cleaner into the bowl water or bowl sides and then manipulating the scrub brush to manually cleanse soiled areas above and below the bowl waterline.
Traditional methods and objects have a number of drawbacks. First, it is often difficult to bring the cleaner into areas above the waterline within the bowl. Some cleaner containers include angled necks allowing cleaner to be directly applied to this surface, but to coat the entire bowl requires more cleaner than would normally be used. Second, a scrub brush is often remains dirty after cleaning the bowl is complete. The brush is swished in semi-clean refill water and removed to dry in a caddy or by simply being stood up in a corner. Finally a user often is sprinkled by dirty water from the bristles of a scrub brush at one time or anther during the cleaning process.
An efficient cleaning method using superior tools is desired. At the conclusion of the cleaning process any tools which must be stored within the bathroom should be clean. Additionally, there should be an easy way to get the cleaner into the areas above the bowl water line.
The present apparatus and method overcomes the shortcomings in the prior art. The present apparatus includes a one time use swab which may be flushed into the toilet drain after the cleaning process is complete. The swab may include a pre-applied detergent thus making it easy to get the detergent into areas above the bowl waterline. The tool which holds the swab provides a way to remove the swab without the users hand contacting the swab. A caddy which supports the tool also provides means for loading a swab onto the tool without a user touching the head of the tool.
In one embodiment the apparatus includes a tool having a handle section and a head having two or more separable portions wherein the portions of the head may be manipulated into multiple configurations by a user of the tool wherein one of the configurations assists in holding a swab upon the head of the tool under a spring bias.
In another embodiment the apparatus includes a tool having a head and a handle section, a flushable swab having a pocket-like configuration and fitting over the head of the tool for attachment thereto wherein the tool has a loading position wherein the swab is placed upon the tool, an operating position wherein the tool assists in holding the swab upon the tool, and a removing position, wherein the tool assists in displacing the swab from the tool. These and other features, aspects and advantages of the present invention will be fully described by the following description, appended claims, and accompanying drawings.

The middle section 40 is adjacent to the handle section 30 and extends in a generally straight direction until bending close to the position where the middle section 40 joins the head 60. The middle section 40 may also be hollow. The head 60 is located adjacent to the middle section 40 opposite of the handle section 30. The head 60 is also preferably hollow. The head 60 may be made of two portions 62 and 64. These portions 62 and 64 may be generally symmetrical shaped halves. The head 60 is shaped in the same general shape as the swab 90 which fits over the head 60. The head 60 may include protrusions, teeth or texturing 70 to assist in holding the swab 90 in place during use. The head 60 may also include one or more holes 61 at the end opposite of the middle section 40 to drain any fluid which may accumulate within the head 60, middle section 40 or handle section 30. At this end of the head 60 the head portions 62 and 64 may also include relieved portions of reduced thickness which provide a small gap between the portions 62 and 64. The gap allows the two head portions 62 and 64 to be opened as described in more detail below without interfering with each other. An additional drain hole 43 is provided within the middle section 40.
In a preferred embodiment, the handle section 30, middle section 40 and head 60 of tool 20 are manufactured from common material which can be any polymer, including: polycarbonate, cycolac or Acrylonitrile Butadiene Styrene (ABS). In one embodiment of the invention one portion of the handle section 30, middle section 40 and head 60 are molded as a single piece. Additionally, the remaining portion of the handle section 30 and middle section 40 are molded in a second piece. This allows the pushrod assembly 50 to be easily placed within the middle section 40 and handle section 30 and sealed in place by attachment of the remaining piece of the handle section 30 and middle section 40. The pieces may be attached by sonic welding techniques or solvent bonding. A number of tabs and slots or other alignment guides may be molded into the tool pieces to facilitate the alignment and joining process. Alignment ribs 41 are molded into the middle section 40 and handle section 30 to provide a guide for the pushrod assembly 50. The alignment ribs 41 may be placed at similar positions upon the matching molded pieces of the middle section 40 or may be offset for the purpose of allowing drainage of any accumulated water within the tool 20. The alignment ribs 41 may also be used for holding the springs 54 or other components of the pushrod assembly 50 in a desired position and as stopping points for motion of the slider washer 55. The second portion 62 of the head 60 may be molded as a solitary piece.
The pushrod assembly 50 fits within the tool 20 and includes a long narrow pushrod 56, the slide control button 52 used to actuate the pushrod 56, springs 53 and 54, a slider washer 55 as well as other washers and clips on either side of the button 52 to assist in moving the button 52 to and from desired positions. The slide control button 52 may be rotated within the handle section 30, however the rotation is constrained by the openings of the slot portion 34. At the end of the pushrod assembly 50 opposite the control button 52 a cam 58 is used to interact with the head 60 of the tool 20. The cam 58 may interact with the head 60 via a cam follower plate 66 used to assist in translating movement of the pushrod 56 to the head 60. The cam follower plate 66 is flat and may be attached to one half of the head 60. The cam follower plate may also include slots on its sides which in combination with pivot pins 68 on the head portion 64 act as a guide mechanism.
The slider washer 55 is affixed to the pushrod 50, but can interfere with the alignment ribs 41 upon the middle section, thus predetermined positions of the pushrod assembly 50 may be reached at these points of interference as described in more detail below.
Another spring 59 is located within the head 60 and affixed at one end to the cam 58 and at another end to the one portion 62 of the head 60 or the cam follower plate 66. Spring 59 makes sure that the head portion 62 does not get disengaged from the pushrod assembly 50. Spring 59 also expands when the head is in the Use position and helps prevent any binding when the tool 20 is moved from the Use to Neutral positions.
The lower portion of the head 62 may include two pivot pins 68. The pivot pins 68 interact with slots on the side of the cam follower plate 66. The pivot pins 68 allow the upper position 62 to be pivoted into the Use position. Additionally the pivot pins 68 guide the movement of the upper position of the head 62 to be extended into the Eject position.

In a preferred embodiment of the swab, the thickness of a single wall of the swab 90 may be about 3.2 millimeters (about ⅛ inch). The tensile strength at about ten percent elongation of a single wall of the swab 90 in a first direction (shown as α in
Prior to or after the formation and machining of the swab 90, additives are introduced to the swab fabric. These additives may include, binders, surfactants, dyes, scent compounds, disinfectants, and/or detergents. The additive combined may have a weight of about 48.35 to about 53.44 grams/sq. meter (about 1.425 to about 1.575 ounces per square yard). Binders which may be used alone or in combination are Polyvinyl Acetate and Polyvinyl Alcohol. The binder may be applied initially on both sides of the cotton/Rayon swab. Additional binder may be added as the remaining additives are applied to the swab. In a preferred embodiment the detergent used is an anionic detergent based on sodium salt of dodecyl benzene sulfonic acid. A preferred detergent is manufactured by Eastern Color & Chemical Co. and has the title #S-175 Anionic Detergent. The surfactant being used may be one or more of the following: alpha olefin sulfonate, ammonium laureth sulfate, sodium lauryl sulfate; triethanlomine lauryl sulfate.
The swab is easily flushable in part due to its size. However, the swab, in a preferred embodiment, is not of the type which is ripped or torn when removed from the tool head. In fact, the swab is of a sufficient strength, in the preferred embodiment, to resist tearing along the swab seams, since the swab is maintained on the tool head during operation, in the tool Use or operating position under spring tension. The swab is initially inserted onto the tool head. The tool handle section and head portions are then moved to the Use position by the user, such that the portions of the head are spring biased apart. The separation of the tool head portions caused by the spring and cam causes the swab to be placed in tension. If the swab were substantially of paper or other thin materials, it would not resist the tension applied by the tool head, particularly once it was immersed in water and used for toilet scrubbing. Additionally the swab components are preferably biodegradable.
