.l `Referring to Figs. 1-3 of the drawings, thefcleaner swab, is constructed vfrom a flat composite laminated pad 10- made up of a filler 11 in the form lof a flat flexible mat Thevfiller mat 11.-

and aflexible wrap sheet 12 therefor. 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 sufficient body to permit sustained effective cleaning therewith. -HMoreover, it should be made of a material which is at least readily flushable in a toilet bowl, so that it will not clogy the plumbing. Desirably, it should be made of an absorbent material readily disintegrable when wet. For that reason, the filler mat 11 consists essentially of a relatively thick sheet or layer 13 of fluff material which may be macerated cellulose, such as wood pulp, molded or pressed; in flat rectangular form. In a specific form, this particular,

filler sheet 13 may be about 6% inches long, 2% inches wide and about 1A inch thick. In vorder to retain the particles of the filler mat 13 against rapid disintegration or ,separation during manu-` form theffluff type filler mat-11. This envelope sheet 14L is desirably a facialtissue, self-disintegrable whenfwet,v and has a length co-extensive with the length of the filler sheet,y

so that its ends are flush with the ends of the filler sheet 13. Instead of the wood pulp filler being enveloped in the tissue 14, it may have one or more sheets of tissue at the top and at the bottom thereof, or'it may be held togetherv merely by a compression pattern in the form of a grid,l or;

the entire filler mat may consist of a number of thin facial tissues similar to the tissue 14 arranged in a stack to form a padding mat for the swab. These superposed tissues could be folded with their longitudinal margins overlapping to produce a mat of the desired thickness.

The' wrap sheet 12 is des'irably of thin fiexible paper easily ushable in a toilet bowl but nevertheless rugged and strong enough to withstand' cleaning or scrubbing. pressure during use. A partially bleached 4rope paper weighing lbs. per 1000 square feet and impregnated with a suitable resin, such as ureaformaldehyde or mel amine, to impart to the paper the required degree of wet strength has been found satisfactory forthe purpose although any paper capable of being similarly processed and which will give equivalent service will sufce.

The wrap sheet 12 is also impregnated with a suitable detergent which is compatible with the resin with which the sheet is treated for control of wet strength. A suitable composition for the purpose is Antorox A-400, which is an ethylene oxide condensation product of substituted phenols having an approximate molecular weight of 660 and whichv is in a class of non-ionic detergents. The nonionic class of liquid detergents is desirable because of its foaming action, permitting high degree of paper impregnation. However, an ionic detergent may be used if it is compatible with the resin with which the sheet is' treated for control of wet strength.

On its outside scrubbing or cleaning surface, the Wrap sheet 12 isdesirably coated with a foaming agent and a suitable composition for the purpose is Orvus Paste, consisting essentially of sodium lauryl sulphate in the class of anionic solid detergents, which will foam but will not give a high degree of impregnation.

The wrap sheet 12 is also treated with a water soluble bluing dye, similar to that used for laundry purposes, to whiten the surfaces cleaned by the swab of the present invention.

The wrap sheet 12 may also contain a suitable disinfectant and a perfume.

The filler mat 11 is in flat rectangular form and the wrap sheet 12 is rectangular except for four rectangular cutouts or recesses 15 in the cornersv of the sheet and, in a specific form is about 11 inches long and four inches wide across its center. The recesses 15 in the wrap sheet are about 1% inches long. The filler mat is laid centrally on the inner face of the Wrap sheet with the overlapping margins of the tissue 14 of the iiller mat against said face. The wrap sheet is wider than the ller mat to define longitudinal edge margins 16 on said sheet projecting beyond said mat and is longer than said filler mat to define endk sections 17 projecting beyond the filler mat. The end sections 17 of the wrap sheet are slightly wider than the filler mat by the extent of thin margins 18 along the sides of said end sections.

' The longitudinal edge margins 16 and 18' of the 'wrap sheet on its inner face have a layer of adhesive which is strong Venough to hold the seams together, while the swab is undergoing the usual period of use but which is weak enough to permit rupture of the swab easily along the seams when the swab is wet and ready for disposal. More specifically, this adhesive may be a thermosetting material, such as urea-formaldehyde or polyvinyl acetate, to facilitate manufacture of the swab.

Figures 1 and 2 show the composite pad 10 with its component parts assembled and ready to be folded and seamed to make the bag swab. For that purpose, the projecting end sections 17 of the wrap sheet 12 are folded inwardly over the ends of the filler mat 11 to retain said mat in proper position on said wrap sheet and to define holder engageable flaps, as will be more fully described. The margins 18 of these flaps 17 are secured to the adhesively coated margins 16 of the main body of the wrap sheet through the adhesive, so that the sides of said aps are closed as` shown in Fig. 3.- In this preliminary folded position shown in Fig. 3, due to the presence of the recesses 15 in the wrap sheet, the portion 20 of the adhesively coated margin 16 of the wrap sheet along the side of each flap 17 will project beyond said flap side and will serve the purpose to be made apparent.

The pad shown in Fig. 3 is then folded upon itself along its transverse center line, as shown in Figs. 4 and 5, to bring` the aps 17 together in face to face contact. By application of heat and pressure, the facing juxtaposed overlapping margins 16, including the portions 20 thereof, are secured together by the thermoplastic adhesive on these margins to form plain lap seams 22 along the sides of the pad, thus forming a pouch or bag swab 25 with the wrap sheet 12 on the outside to define a scrub sheet and with the ller mat 11 on the inside to form a lining or backing for the scrub sheet, it being noted that said filler mat is entirely enclosed and protected against separation from the wrap sheet as well as against disintegration. Because of the presence of the adhesively coated portions/20 of the sheet margins 16 which project beyond the sides of the flaps 17, the folded pad will be closed entirely along its sides. The filler mat 11 in the resultant swab 25 will be retained against separation from the wrap sheet 12 and against disintegration during use by the seams 22 along its sides and by the flaps 17 folded over the ends of said mat. These flaps 17 serve not only to protect the filler mat 11 as indicated but in addition are intended to be latched to a projection or projections on the holder head, when the swab 25 is slipped over said head.

Figures 6 to 14 show a type of holder 30 which is ad'- vantageously employed in connection with the pouch or bag swab 25. This holder 30 has a head constructed of. parts relatively movable to burst and break apart the swab 25 latched thereto, so that the swab can be removed from said head and opened up to facilitate the separation of the scrub sheet and filler material and allow them to be ushed away more readily.

The holder 30 is about 15 inches long and is desirably made of a material which can be easily cleaned and kept sanitary. For that reason, it is desirable to make the holder 30 of suitable moldable plastic material, such as polystyrene.

In the specific embodiment shown, the holder 30 is in the general form of a spoon or spatula and comprises a head 31 adapted to be hooded or covered by the swab 25 and a handle or shank 32 therefor terminating in a grip portion 33. The head 31 is offset from the shank 32 and is generally in the form of a lyre or anchor having a pair of hooks, spurs or flukes 34 adapted to catch on to the flaps 17 of the bag swab 25 when the latter is slipped over the head. The sides 35 of the head 31 at its forward end extend up to and along the flukes 34 and are inclined with respect to the longitudinal axis of the holder to taper said end foreasy entry of the head 31 into the pocket of the swab 25.

To assure more positive catch engagement between.

the ilukes 34 and the flaps 17, the upper faces of the linkes are raised to form triangular beveled flanges 39 thereon.

The holder 30 is designed to rupture the swab after use and towards that end, the holder is split longitudinally along its full length to form two opposed sections 36 and 37 jointed together at its head 31 for relative movement. In the specific form shown, these two sections 36 and 37 are pivoted together at the toe 38 of the head 31.

The handle parts of the holder sections 36 and 37 are -semicircularly channeled and are thus tubular when these sections are closed together, and the head parts 40 and 41 of the holder sections respectively are provided with raised rim edges 42 and 43 to dish out said head parts and to cause them to define conjointly a hollow head construction in closed position.

The head part 40 of the lower holder section 36 has desirably 'an imperforate base, and the upper head'part 41 of the upper holder section 37 has a slot 46 extending therealong to the toe and serving tov dra-inA the interior` 'of` the hollow head 31 when closed and to define spaced arms 47 forming part of the hinge connection between the two head parts 40 and 41. This hinge connection comprises a knuckle 50 on the lower head part 40 flanked by the arms 47 on the upper part 41 and secured thereto by hinge pins 51 on said arms journalled in said knuckle. The arms 47 are resilient enough to allow the hinge pins to be snapped into place.

To hold the two sections 36 and 37 releasably together, the upper section 37 has a latch pin 53 depending from a bracket ange'54 at its outer grip end, and the lower section 36 has a latch ange 55 with a catch opening 56 therein for the latch pin. This catch opening 56 has a straight inner pin camming edge 57, and the latch pin 53 has its inner edge bevelled to form a long shallow notch 60 in said pin. The latch pin 53 is so located with respect to the catch opening 56 that the pin does not pass freely through said opening but must be forced therethrough, and its lower end is rounded to permit said pin to be forced into the catch opening and to be cammed by the inner edge 57 of said catch opening sufficiently to allow said pin to pass into said opening. The pin 53 has enough resiliency to permit it to be forced in the catch opening 56. By pressing the two holder sections 36 and 37 together near the handle grip portion 33, the pin S3 will enter the catch opening 56 until the edge 57 of the catch opening 56 extends into the notch 60 in the pin 53. In this position, shown in Figs. 7 and 11, the two holder sections 36 and 37 will be latched together in closed position. To release the latch connection, the pin 53 is forced out of the opening S6, as for example by thumb pressure.

The latch flange 55 at the end of the lower holder section 36 extends beyond the latch opening 56 therein and the extension has a hole 62 for hanging the holder when not in use.

To hold the two holder sections 36 and 37 from relative sideways displacement, the shank parts of the handle holder sections are provided with opposed semi-circular discs 65 and 66 rigidly secured therein, one of said discs having a tongue 67 and the other disc having a recess 68 for receiving said tongue.

In preparing the cleaning device for use, a bag swab 25 is slipped over the head 31 of holder 30, while the sections 36 and 37 of said holder are latched together in closed position, as shown in Fig. 12. When the swab is in place, the ends 70 of the internal flaps 17 extend beyond the ends of the iiukes 34. Since they converge towards the side seams 22 of the bag swab 25, these flap ends 7l) near said seams cross the ukes 34 on the holder head 31 and catch on to said dukes. The swab 25 is thereby latched and locked to the holder head and cannot be removed therefrom, without rupturing the swab. The widening of the flukes 34 by the provision 0f the bevelled anges 39 thereon, assures a more positive lock between these iiukes and the aps 17.

The holder 30 and the swab 25 attached thereto form a cleaning device which can be conveniently handled. For example, in cleaning a toilet bowl, the swab 2S 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 head can then be manipulated by passing the swab 25 over the surfaces to be cleaned. The wrap sheet 12 presents an effective rubbing or scrubbing surface and the filler mat 11 supplies the necessary body to the swab and also permits it to be deformed to conform with the irregularities in the surfaces being cleaned. The wrap sheet 12 is impervious to the passage of filler material therethrough even when said sheet and said ller are wet, so that disintegration of the filler mat 11 can not take place during normal period of use.

The holder head 31 constitutes the bulk of the cleaning element and affords the necessary backing and support for the thin-walled swab 25, so that substantial pressure can be supplied to the swab through the holder, while the swab retains its general form. The Iiller mat 11 tends to disintegrate upon being wet but is retained against disintegration by the protective enveloping action of the wrap sheet 12.

After the cleaning operation has been completed, the latch pin S3 is released at the grip end of the two handle sections 36 and 37 by thumb manipulation as previously described, and the two sections are then pulled apart to cause them to open up about the hinge connection at the toe 38 into some such position as shown in Fig. 14. This causes the side seams 22 of the swab to be broken and the swab to be ruptured. In thi-s ruptured condition, the swab will easily fall of the head by itself without direct hand contact with the swab. The ruptured swab will drop into the bowl, and since it is opened up, the filler mat 11 will be exposed immediately to the disintegrating action of the water in the bowl, separating from the wrap sheet 12 and enabling the components of the swab to be easily washed away by flushing and without danger of clogging the drain.

Also, as far as certain aspects of the invention are concerned, instead of having a holder with its head in the form of a lyre or anchor and its hooks 34 for engaging the flaps 17 of the swab in the form of ilukes, the head may have a flap engaging catch on one or each of its faces in the form of a wedge tapering forwardly towards the toe of the head and merging into the surface of the head at its forward end for easy entry into the pocket of the swab.

In short, the invention in its broader aspects contemplates any form of holder having a head which is insertable into the swab and which can be expanded to rupture the swab after use.

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, which x the metes and bounds of the invention.
