Johnson, Jr., Piscataway Township, .Middlesex County, Viggo I. Korsgaard, Middlesex, and Roland R. Nydegger, Metuchen, N. J., assignors to Personal Products Qorporation, a corporation of New Jersey Application November 9, 1951, Serial No. 255,652

11Claims. (CL 15-210) The present invention relates to cleaning devices having disposable cleaning elements and more particularly to devices suitable for cleaning toilet bowls and the like.

Copending application Serial No. 214,918, filed March 19, 1951, and containing the broader claims discloses acleaning swab comprising a pad constructed, folded and seamed in the form of a pouch or bag. This bag swab has internal flaps adapted to be latched automatically to a catch or catches on the head of a 'holder when the swab is slipped on said head to retain the swab securely thereon during use. The bag swab is constructed to permit it to be easily ruptured and opened up, so that it can be removed from the holder head and dropped in the toilet bowl for disposal. For rupturing the bag swab so that it can be removed from the holder head for disposal, said head is constructed with relatively movable parts.

The present invention is a modified form of cleaning device disclosed in the aforesaid copending application and has for its object to provide a cleaning swab which is of the general type disclosed in said copending application but which does not require a holder with relatively movable head parts to rupture the swab when it is desired to remove the swab from the holder and to dispose of the swab.

In accordance with certain of the broader features of the present invention, a string is provided in combination with the cleaning swab, located and arranged with respect to the swab, so as not to interfere with its cleaning operation, and manipulable to cause said swab to be ruptured by the string While on the holder head and to permit thereby ready disposal of said swab.

in one form of the invention, the string is built into the swab to form a disposable unit therewith and is so arranged with respect thereto that when the swab is slipped over the head of the holder, the string is made to extend from the swab along the handle portion of the holder to an attachment point. After the cleaning operations have been completed, the string is released from the attachment point and pulled away from the handle and head parts of the holder, to rupture the swab, so that it can be removed from the head of the holder and dropped in the toilet bowl with the string for disposal.

In accordance with another form of the invention, the string is separate from the swab but is attached at one end to the head of the holder, while the other free end is adapted to be removably fastened to an attachment point on the handle or grip part of the holder. The swab is slipped over the head of the holder for latch attachment thereto and over the part of the string extending along said head. After the cleaning operations have been completed, the string is released from the attachment point on the holder and is manipulated to rupture the swab and cause its removal from the holder head for disposal purposes. The string remains on the holder and can be used indefinitely for successive swabs.

Various other objects, features and advantages of the invention are apparent from the following particular description and from an inspection of the accompanying drawings, in which:

Fig. 10 is a perspective of another form of holder head which may be employed in connection with the cleaner swab of Figs. 1 to 8 having the built-in rupturing string;

Fig. 11 is a face view of another form of cleaner swab similar tothat of Figs. 1 to 8, except that it has no builtin rupturing string; and

Fig. 12 is a perspective of a form of holder with attached string separate from the cleaner swab and adapted to rupture said swab.

Referring to Figs. 13 of the drawings, the cleaner swab is constructed from a flat composite laminated pad 10 made up of a filler 11 in the form of a flat flexible mat and a flexible wrap sheet 12 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. The filler mat 11, however, must have sufiicient body to permit sustained effective cleaning therewith and should be made of a material which is at least readily fiushable in a toilet bowl, so that it will not clog the plumbing. Desirably, it should be made of an absorbent material readily disintegrable when wet. For that reason, the filler mat Ill consists essentially of a realtively thick sheet or layer 13 of 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 A. inch thick.

In order to retain the particles of the filler mat 13 against rapid disintegration or separation during manufacture, storage, transportation or use, a sheet or napkin 14, of very thin paper which is at least fiushable and which is desirably water-disintegrable, is enveloped around the filler sheet 13, with its longitudinal margins overlapping to form the fluff type filler mat it. This envelope sheet 14 is desirably a facial tissue, self-disintegrable when wet, and has a length c'o-extensive with the length of the tiller sheet so'that its ends are flush with the ends of the tiller sheet 13.

Instead of the wood pulp filler being enveloped in the tissue 14, it may have one or more sheets of tissues at the top and at the bottom thereof, or it may be held together merely by a compression pattern in the form of a grid, or the entire filler mat may consist of a number of thin facial tissues similar to the tissues 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 desirably of thin flexible pa er easily fiushable in a toilet bowl but nevertheless rugged and strong enough to withstand cleaning or scrubbing pressure during use. A partially bleached rope paper weighing lbs. per 1000 square feet and impregnated with a suitable resin, such as urea-formaldehyde or melamine, to impart to the paper the required degree of wet strength has been found satisfactory for the purpose, although any paper which is capable of being similarly processed and which will give equivalent service will suffice.

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 which is in the class of non-ionic detergents. The non-ionic 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 is desirably 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 could contain, if desired, one or more materials such as a suitable disinfectant, a scouring agent such as pumice or diatomaceous earth, and a perfume.

The filler mat 11 is in flat rectangular form and the wrap sheet 12 is rectangular except for four rectangular cut-outs or recesses 15 in the corners 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 12 are about 1% inches long.

The filler mat 11 is laid centrally on the inner face of the wrap sheet 12 with the overlapping margins of the tissues 14 of the filler mat against said face. The wrap sheet 12 is wider than the filler mat 11 to define longitudinal edge margins 16 on said sheet projecting beyond said mat and is longer than said filler mat to define end sections 17 projecting beyond the filler mat 11. The end sections 17 of the wrap sheet 12 are slightly Wider than the filler mat 11 by the extent of thin margins 13 along the sides of said end sections.

The

longitudinal edge margins

16 and 18 of the wrap sheet 12 on its inner face have a layer of adhesive which is strong enough 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 ureaformaldehyde or polyvinyl acetate, to facilitate manufacture of the swab.

Figs. 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. To produce a bag swab with a built-in rupturing string, a string 19 of the required length and of sufficient strength to withstand the tension thereon in the operation of rupturing the swab is laid along the composite pad 10 in its initial form shown in Figs. 1 and 2. This string 19 which may be of any suitable material, as for example of fibrous material such as silk, cotton, linen, or of plastic such as nylon, is laid preferably off-center on the composite pad 10 near one longitudinal side of said pad and is secured in this position to the filler mat 11 and the wrap sheet 12, as shown in Figs. 1 and 2, by adhesive of the type which is not materially weakened by the water during cleaning action. One end of the string 19 is flush with one end of the wrap sheet 12, while the other end extends beyond the corresponding end of said wrap sheet to define a string section 21 long enough to extend to the grip end of the holder in attached position of the swab, as will be more fully described.

With the composite pad 10 and string 19 arranged and adhesively secured together as described and shown in Figs. 1 and 2, the projecting end sections 1'7 of the wrap sheet 12 with adhesively attached string sections 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 ad hesively coated margins 16 of the main body of the wrap sheet through the adhesive, so that the sides of said flaps 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. Also in this preliminary folded position, one end section 22 of the string 19 will be doubly folded and retained between one flap 17 and the inner face of the body of the pad and the intermediate section 23 of said string will be doubly folded and retained between the other flap 17 and the inner face of the body of the pad, as shown in Fig. 3.

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 flaps 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 24 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 filler mat 11 on the inside to form a lining or backing for the scrub sheet. It should be noted that the filler mat 11 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 24 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.

In doubly folded pouch or bag position of the pad shown in Figs. 4 and 5, the section 21 of the string 19 will project from the pocket and from the mouth of the bag swab.

Figs. 6 to 9 show a type of holder 30 which is advantageously employed in connection with the pouch or bag swab 25. This 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 30is in the general form of a spoon or spatula and comprisesahead-Sl adapted to be hooded or covered by the swab 25 and a handle or shank 32 therefor terminatingin a grip portion 33. The head 31 is offset from the shank 32 and is generally in the form of a lyre having a pair of hooks, spurs or fiukes 34 adapted ,to catch on to the flaps 17 of the bag swab 25 when the latter is slipped over the head. The forward edge 35 of the head 31 is convexly curved and the sides of the fiukes 34 are inclined with respect to the longitudinal axis of theholder 30 to taper said end for easy entry of the head 31 into the pocket of the swab 25.

The outer end of the grip portion 33 of the holder 30 carries a button 36 aroundwhich the free end of the rupturing string 19 of the swab is adapted to be wound in cleaning position of the swab on the holder 30, as shown in Fig. 6.

In preparing the cleaning device for use, a bag swab 25 with a built-in rupturing string 19 is slipped over the head of the holder 30. When the swab is in place, the ends 40 of its internal flaps 17 extend beyond the ends of the flukes 34. Since the opposed flaps 17 converge towards the side seams 24 of the bag swab 25, these flap ,ends 40 near said seams across the flukes 34 on the holder head 31 and catch on to said flukes, as shown in Figs. 7 and 8. The swab 25 is thereby latched and locked to the holder head 31 and cannot be removed therefrom without rupturing the swab. The section 21 of the string 19 will project outwardly from the mouth of the swab 25 when said swab is latched on to the holder head 31 in the manner described. This projecting string section 21 is extended along the shank or handle 32 of the holder 31) and its free end is anchored by winding it around the button 36 on said handle, as shown in Fig. 6. The cleaning device with the string 19 so arranged can be used without interference from said string.

The holder 34) and the swab 25 attached thereto form a cleaning device which can be conveniently handled. For example, in cleaning a toilet bowl, the swab 25 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 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 filler are wet, so that disintegration of the filler mat cannot 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 filler 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 end of the string 19 is unwound from the button 36, and the projecting section 21 of the string is pulled in a direction substantially at right angles to the general plane of the holder head 31 and away therefrom to cause the panel section of the swab 25 directly connected to the base end of the string section 21 and located on one face of the holder head 31 to break along the seam 24 nearest to the string 19 and away from the panel section of the swab 25 on opposite face of the holder head.

The breaking of the seam 24 nearest to the string 19 can also be accomplished by pulling the projecting section 21 of the string 19 sideways of the holder 30 to cause said string to pass between the overlapping swab parts of said seam and to rip thereby said seam open.

I 6 After the initialseam opening manipulation of the pr'o jecting section 21 of the string 19 as described, thisprojecting string section is continued to be pulled in any direction that will cause the swab to be more completely ruptured and to be pulled off the head 31 of the holder 30. The ruptured swab with the string 19 attached thereto is then dropped into the toilet bowl. Since the'ruptured swab in the bowl is opened up, the filler mat 11 will be exposed to the disintegrating action of the water in the bowl, thereby causing the components of the swab and the rupturing string to be easily washed away by flushing without the danger of clogging the drain.

'Fig. 10 shows another type of holder 31% with a head '31 which can be used in connection with the pouch or 'bag swab 25 having the built-in string 19 as shown in 'Figs. 1-8. This holder head 31 is in the form of a flat plate having a rounded forward edge 35 to permit its easy entry into the pocket of the swab 25 and having a spot 42 extending from one face of said plate and shown in the form of a wedge tapeding towards the forward end of the holder to merge at one end into the face of the holder head 31 and defining at its opposite rear end a catch shoulder 43.

In use, the swab 25 is slipped over the holder head 31 as far as it will go, so that the holder head will be located between the flaps 17 and the spur 42 will be located inwardly beyond the edges of these flaps in position to cause its catch shoulder 43 to engage one of said edges midway between the seamed sides of the swab before the swab is withdrawn too far from said holder head. The swab 25 is therefore retained on the holder head 31 during normal cleaning operations, with the built-in string 19 projecting from the swab and extending along the shank or handle of the holder 30 and the free end of said string attached to a button or other anchor device (not shown) on the handle.

After cleaning operations, the swab 25 can be ruptured by tensional manipulation of the string 19 and pulled off the holder head 31 for disposal, as described in connection with the construction of Figs. 19.

In the cleaning devices of Figs. l-lO, the string 19 is built into the swab 25 to form a disposable unit therewith. In the cleaning device of Figs. 11 and 12, the swab 25 is exactly of the same construction, except for the absence of the built-in rupturing string. Instead, a rupturing string 19 is provided, forming a unit separate from the swab 25 and attached to the holder used in conjunction with this swab 25 to form a permanent unit therewith. This modified form of construction facilitates manufacture of the swab 25 and permits reuse of the same string indefinitely, thereby effecting economy. The modified construction illustrated may be employed in connection with either of the types of holders shown in Figs. 9 and 10. Specifically, it is shown in Fig. 12 with a holder 30 made desirably of plastic such as polystyrene, and having a lyre head 31 similar to that of Fig. 9.. This holder 30 has a shank or handle 32 and a grip portion 33 provided at its outer end with a V-notch 45 for receiving the outer free end of the swab-rupturing string 19*. A button 36 secured to the underside of the grip portion 33 near but inwardly beyond the apex of the Vanotch 45 serves as an attachment or anchoring post for the outer end of the string 19 when the holder 30 is not in use or when the holder is set up with the cleaning swab 25 latched to the head 31' of said holder.

The swab-rupturing string 19 may be made of fibrous material such as silk, cotton, linen or the like or may be of metal in the form of a wire, but is desirably of plastic and specifically of nylon.

One end of this string 19 is permanently anchored to the holder head 31 at its forward edge by any suitable means, and is shown fastened in central position with re spect to said head, so that the string extends centrally along the holder 30*! when the holder is not in use, as

shown in Fig. 12 or when the holder is set up with the swab 25 latched thereto in preparation for cleaning.

To set up the device of Figs. 11 and 12 for cleaning, While the string 1% extends along the holder 30 and while the free end of said string is fastened to the button 36 or other attaching device employed, as shown in Fig. 12, the swab 25 is slipped over the holder head 31* until it is latched thereto, as described in conjunction with the device of Figs. 1 to 9. The string 19 positioned as described does not interfere with the quick automatic latching of the swab 25 onto the holder head 31 and will extend along the swab midway between its side seams 24 After the cleaning device has been used in the manner described in connection with Figs. 1-9, the free end of the string 19 is released from attachment to the button 36 and the string 19 is manipulated to rupture the swab. The manipulation of the string 19 for this purpose may be effected by pulling the string sideways of the swab 25 first in one side direction and then in the other to cause the side seams 24 of the swab to be opened by the shearing action of the string between the superposed layers of said scams, or may be effected by pulling the string away from the holder head 31* in a direction to draw the top panel of the swab on one side of the holder head away from the other panel of the swab on the opposite side of the holder head and to break the side seams 24 open. Depending on the strength and character of the side seams 24 and the strength of the wrap sheet on the swab 25 the string 1% may be pulled in any direction to give any tear action desired, either by breaking of the seams as indicated or by the tearing of the wrap sheet. After the initial rupture of the swab 25 has been effected, the string 19 can be further pulled and manipulated in different directions to cause the ruptured swab to drop off the holder head 3:1 and into the bowl Where it can be easily flushed.

While the invention has been described with particular reference to specific embodiments, 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.
