16 Claims. (Cl. 15-210) The present invention relates to cleaning devices hav ing disposable cleaning elements and more particularly to devices suitable for cleaning toilet bowls and the like.
One object of the present invention is to provide a new and improved cleaning swab, which can be firmly attached to a permanent holder for use as a mop in cleaning toilet bowls and the like, which can be easily removed from the holder and dropped into the bowl after use without the necessity of direct finger contact therewith, which is constructed to withstand disintegration or separation of its parts during a normal period of use but which will separate into parts easily tlushable in a toilet bowl after release from the holder, which lends itself to inexpensive manufacture on a mass production scale, and which pre sents a large cleaning surface in comparison to its bulk.
Another object is to provide a new and improved cleaning device including a cleaning swab and a holder therefor, constructed to permit the swab to be readily applied thereto and to cause the swab to be firmly retained thereon during a normal period of use; designed to give shape and bulk to the swab when in use and to afford an effective backing therefor in the cleaning operation; and provided with a swab retaining head of simple construction with no movable parts.
In accordance with certain features of the present invention, the cleaning swab comprises basically a composite pad having a filler sheet of soft desirably absorbent material which is easily disintegrable when wet and a thin flexible wrap sheet therefor disintegrable when wet but having a wet strength sufficient to prevent disintegration of said ller sheet in use. The iller sheet gives the necessary body to the pad for effective cleaning and the wrap sheet is arranged with respect to said filler sheet to serve as a padded wiper or scrubber. The composite pad so constructed is rolled into the form of a tube or sleeve and in this form is slipped over the head of a holder for cleaning use.
The holder head has annular projecting conformations desirably of helical shape to effect a more positive connection between said head and the soft, flexible, conformable walls of the tubular swab.
In an alternative form of swab embodying the present invention, a string is built into the swab to form a rib-like conformation thereon when the swab is slipped over the head of the holder. This rib-like conformation is adapted to catch on to a spiral convolution of the holder head, thereby serving to hold the swab more securely onto said holder head.
Various other objects, features and advantages of the invention will be apparent from the following particular description and from an inspection of the accompanying drawings, in which:

Fig. 7 is a fragmentary perspective showing the cleaning swab of Fig. 5 attached to the head of the holder shown in Fig. 6;
Fig. 8 is a face View of another form of fiat composite cleaner pad in an intermediate stage of manufacture, embodying certain features of the present invention and including built-in strings for forming ribs when the pad is rolled into sleeve form and when the resulting swab is impaled upon the holder head;
Fig. 9 is a section of the pad taken on lines 9-9 of Fig. 8;
Fig. l0 is a face view of the pad illustrated in Figs. 8 and 9, but shown after the wrap sheet has been wrapped completely around the filler sheet to bring the opposite longitudinal margins of the wrap sheet in overlapping relationship and after these overlapping margins have been adhesively secured together;
Fig. ll is a transverse section of the composite pad taken on lines 11--11 of Fig. l0;
Fig. l2 is a transverse section of a cleaner swab made by rolling the composite pad of Figs. l0 and 1l into the form of a sleeve and adhesively securing the opposite ends of the pad together; and
Fig. 13 is a fragmentary perspective showing the cleaning swab of Fig. 12 attached to the head of the holder shown in Fig. 5.
Referring to Figs. l to 4 of the drawings, the cleaner swab is constructed from a fiat composite pad 10 made up of a filler 11 in the form of a fiat flexible mat or sheet and a flexible paper wrap sheet l2 therefor. The filler mat 11 serves as the padding for the swab and is desirably of soft material to yield into conformance with irregularities in the surfaces being cleaned and must have sutiicient body to permit sustained effective cleaning. Moreover, it should be made of a material which is at least readily liushable in a toilet bowl, so that it will not clog the plumbing. For that reason, the filler mat 11 is made of an absorbent material readily disintegrable when wet and consists essentially of a relatively thick sheet or layer of fluffy particulate material which is desirably macerated cellulose, such as wood pulp, molded or pressed in flat rectangular form. ln a specific form, the filler sheet 11 may be l() inches long, 2% inches wide and about 1A inch thick.
As far as certain aspects of the invention are concerned, instead of wood pulp the filler may consist of a number of thin facial tissues arranged in a stack to form a padding mat for the swab.
The wrap sheet 12 is desirably of thin exible paper easily liushable in a toilet bowl but nevertheless rugged and strong enough to withstand cleaning or scrubbing pressure during use. To that end, the wrap sheet 3.2 has a wet strength high enough to permit it to withstand disintegration during a normal period of use but low enough to cause it to decompose and reduce to fragments for ready drainage after that period. The ller 11 has a tendency to disintegrate mach faster. bntits disintegration 3 is retarded by the protective enveloping action of the more resistant wrap sheet 12.
The filler mat 11 is in at rectangular form and the wrap sheet 12 is rectangular and wide enough to permit the longitudinal margins of the sheet to be folded over the mat and brought together in overlapping relationship. The wrap sheet 12 is longer than the filler mat 11 so that the ends 13 of said sheet extend beyond the ends of the filler mat.
In an intermediate stage of manufacture, the filler mat 11 is placed centrally on the wrap sheet 12, as shown in Figs. 1 and 2, and the longitudinal margins of the wrap sheet are folded over the filler mat to bring these margins in overlapping relationship and to form a lap seam 15 thereby. These overlapping sections of the wrap sheet 12 are secured together by water disintegrable means in the form of a water soluble adhesive to form the coniposite pad shown in Figs. 3 and 4. The adhesive may, for example, be cornstarch but any other adhesive weakening as the result of the action of water thereon may be ernployed, as for instance, methyl cellulose, carboxyethyl cellulose, polyvinyl alcohol, casein, glue and any other water-soluble agglutinant.
The composite pad of Figs. 3 and 4 is rolled with the seam of the wrap sheet 12 on the inside and the opposed ends of the pad are secured together to produce a cleaning swab 16 in the form of a substantially cylindrical sleeve, as shown in Fig. 5. The ends of the pad may be secured together in any suitable manner. For example, the ends 13 of the wrap sheet 12 projecting beyond the corresponding ends of the ller Amat 11 may be folded radially inwardly and secured together face to face by water soluble o-r disintegrable adhesive of the type referred to in the making of the seam 15 on the wrap sheet 12, to form the sleeve swab 16 shown in Fig. 5. The extent of inward radial projection of the ends of the wrap sheet 12 where they are joined together is too small to interfere with the entry of the head of an appropriate holder into the sleeve swab.
In an alternative form of construction (not shown), the projecting ends 13 of the wrap sheet 12 in the flat composite pad are crimped on one face near the corresponding end of the filler mat 11, so that one end 13 is displaced into position ush with one face of the pad body and the other end is displaced into position ush with the other face of the pad body. In the formation of the sleeve swab, the pad is rolled and the ends of the pad body brought together to form a butt joint, while the projecting ends 13 of the wrap sheet 12 are arranged with one sheet end overlapping the outer periphery of the rolled pad body and the other sheet end overlapping the inner periphery of the rolled pad body. In this rolled position, the contacting and overlapping parts of the pad body and pad ends are adhesively secured together by a water disintegrable adhesive.
The wrap sheet 12 of the cleaning swab inthe construction shown may be impregnated with an appropriate detergent, coated with a suitable foaming agent and treated with a water soluble bluing dye similar to that used for laundry purposes, to within the surfaces cleaned by the swab of the present invention. The wrap sheet 12 may also contain a suitable disinfectant, a scouring agent such as pumice, and a perfume.
In the rolled sleeve form of swab shown, the wrap sheet 12 will be on the outside to dene `a scrub sheet and the ller mat 11 will be on the inside to form a lining or back ing for the scrub sheet, it being noted that said ller mat is entirely enclosed and protected against separation from the wrap sheet as well as against disintegration.
Figs. 6 and 7 show a type of holder 20 which is advantageously employed in connection with the swab 16 and which is desirably of plastic material such as polystyrene. This holder has a head 21 adapted to be slipped into the swab- 16 yfor cleaningus, anda handle or shank 22 terminating in a grip portion 23.
The holder head 21 is formed with a series of spaced annular projecting convolutions to bend and fold parts of the swab walls radially inwardly between successive convolutions and into catch engagement therewith when said head is slipped into a tight swab. In the specific form shown, the holder head 21 is in the form of a single or multiple screw having a helical convolution or thread with the crown of this convolution rounded olf to facilitate entry of said head into the swab and to permit the molding of the flexible or yieldable wall of the swab more easily into engaging conformance with said convolution. The holder head is thus adapted to fit tightly into the hollow of the sleeve swab 16 and to hold the swab firmly thereon until it is ready to be discarded, as shown in Fig. 7. The attachment of the cleaner swab 16 onto the holder head 21 can be facilitated by rotating these parts relatively to each other while the swab is being pressed axially on to the holder head.
The holder 20 and the swab 16 attached thereto form a cleaning device which can be conveniently handled. For example, in cleaning a toilet bowl, the swab 16 is dipped into the water in said bowl to render the detergents on the wrap sheet 12 active and to dissolve the bluing thereon. The cleaning can then be effected by passing the swab 16 over the surfaces to be cleaned. Under these conditions, the wrap sheet 12 presents an effective rubbing or scrubbing surface and the tiller mat 11 supplies the necessary body to the swab 16 and also permits it to be deformed to conform with irregularities in the surfaces being cleaned. The wrap sheet 12, being able to withstand disintegration during a normal period of use, protects the ller mat 11 against disintegration during that period.
The holder head 21 constitutes the bulk of the cleaning element and affords the necessary backing and support for the thin walled swab 16, so that substantial pressure can be supplied to the swab through the holder, while the swab retains its general form.
After the cleaning has been completed, the swab 16 is slipped off the holder head 21 without the necessity of directly fingering it. The removal of the spent swab 16 can be effected, for example, by shouldering the swab against the rim of the toilet bowl and pulling the holder 20 away. This causes the swab 16 to slip off or to be stripped oif the holder head 20 and to drop into the bowl. Furthermore, action of the water on the swab 16 dissolves the adhesive along the adjoining ends of the pad forming the swab and ralso along the longitudinal seam 15, so that the scrub sheet 12 opens up while it is disintegrating. This allows disintegration of the filler mat 11 by the action of the water thereon, permitting said mat as well as the wrap sheet 12 to be flushed and drained away in the toilet bowl without -clogging the pipes.
Figs. 8 to 13 illustrate still another form of the sleeve swab 16a made from a composite pad which is similar to that shown in Figs. 1 to 7, but which in addition has an mternal built-in string construction serving to form reenforcing ribs for more secure engagement thereof with the spiral head 21 of the holder 20. The built-in string construction herein shown comprises two parallel strings 25 laid along the wrap sheet 12 between said sheet and the filler mat 11, as shown in Figs. 8 and 9, and retained in position by friction or if desired by adhesive. These strings 25 may be made of any suitable fibrous natural material, such as cotton, silk or linen, or if desired of synthetic material such as rayon or nylon.
The assemblage illustrated in Figs. 8 and 9 is folded as shown in Figs. 10 and l1 with the longitudinal margins of the wrap sheet 12 secured together in overlapping relationship to form a wrapped pad similar to that indicated in Figs. 3 and 4. The resulting pad is then rolled and the opposite ends 13 of the wrap sheet 12 projecting beyond the ends of the ller sheet 11 are brought together and secured in face to face contact by a water soluble or disintegrable adhesive of the type indicated in connection with the swab construction of Figs. 1 to 4 to form the sleeve swab 16a shown in Figs. 12 and 13.
The strings 25 in the sleeve swab 16a will be in the general form of rings extending circumferentially along the inner periphery of the wrap sheet 12 and holding the sections of the swab in the respective transverse planes of the rings against radially outward expansion resulting from the pressure action of the spiral holder head 21 thereon, while the intermediate sections of the swab between these rings and the end sections beyond these rings are permitted to a limited extent to expand radially outwardly by the pressure action of the holder head. This holder head 2l is large enough to fit tightly in the hollow of the sleeve swab 16a, as shown in Fig. 13, so that the intermediate sections of the swab between the strings 25 and the end sections beyond these strings bulge radially outwardly, causing the sections of the swab in the planes of the strings to form radially inwardly extending ribs which catch on to the spiral convolution or convolutions of said head and serve thereby to hold the swab 16a' firmly on to said head during normal use. After use, the swab 16a can be removed from the holder head 21 and discarded in the toilet bowl in the manner described in connection with the constructions of Figs. l to 7.
In t-he specifi-c form of holder 20 shown, the head 21 is of solid construction and has the axis of its screw conformation extending lengthwise or substantially coaxial of its handle portion 22. However, as far as certain aspects of the invention are concerned, the head of the holder may be in the form of a wire spirally bent with its axis extending lengthwise of its handle portion or if desired at 90 thereto. Moreover, the screw head instead of being generally in circular cross-section or contour as shown, may as far as certain aspects of the invention are concerned be generally at, oval or elliptical in cross-section or contour in a plane at right angles to its axis.
While the invention has been described with particular reference to specific embodiments of swab and holder, it is to be understood that it is not to be limited thereto but is to be construed broadly and restricted solely by the scope of the appended claims.
