Description

Brush head assembly and toilet cleaning assembly {SINGLE-USE TOILET BRUSH HEAD}

Generally, toilet brushes are used to remove dirt on the toilet side by swirling cleaning chemicals around the toilet and then rubbing the sides of the toilet with the cleaning chemical and water. Such brushes typically have a brush brush permanently attached to the handle of the brush.

After using such a brush, consumers will generally try to flush the brush by swirling the brush into the toilet. This process can be repeated with one or more additional rinse flushes. This can generally rinse most of the cleaning chemicals and dirt found in the toilet, but the brush typically still has some contaminants even after excessive rinsing. As a result, such a brush may have an unpleasant smell or appearance while it is provided.

Nevertheless, these brushes will drain immediately after use. Thus, consumers will often shake the brush over the toilet to remove water and then quickly move the brush to the beach bucket. This can cause some liquid to fall to the floor. In this case, there is a need for a brush place for collecting the falling water.

To address the drawbacks associated with conventional toilet brushes, permanent brush handles with disposable / replaceable brush heads have been developed. These brushes are designed such that the brush head can be flushed into the toilet after use. Some heads permeated the cleaning composition without the need for additional cleaning chemicals.

However, disposable brush heads that infiltrated the concentrated cleaning composition were not easy to handle because direct contact with the cleaning composition could cause skin irritation in some users. In addition, although the head may be small enough to be "flushable", the brush head is relatively dense compared to a large amount of toilet paper, which may cause problems in certain waste systems such as sensitive and reactive perishable systems. This problem can be exacerbated by any extra structures (eg, cardboard bands) used to hold the brush head parts together.

In other conventional devices, the disposable brush head is formed of a material that dissolves well in water. Unfortunately, this may start to fall before the cleaning process is completed, especially before a radical rub is attempted. In addition, these materials can be so flexible that it is difficult to transfer friction from the handle to the brush head portion.

Accordingly, there is a need for improvements to toilet brushes having replacement brush heads. In view of the above problems, a disposable brush head that is easy to handle is preferred. It is also desirable for the brush head to make the piping less clogged. It is also desirable that the brush head remains intact enough to adequately clean the toilet.

In one embodiment of the invention, the disposable brush head assembly maintained by the toilet bowl cleaning device, the pad; Cleaning compounds; And a water soluble film configured to receive the pad and the cleaning compound.

In another embodiment of the present invention, the disposable brush head assembly held by the toilet bowl cleaning device includes a laminate of a plurality of layers of substrates. The water-soluble film is configured to receive the laminate and the cleaning compound, the film having a plurality of openings. The opening is small enough to accommodate the particulates in the film.

In still another embodiment of the present invention, a toilet cleaning assembly includes a handle; And a disposable flushable pad comprising a strip material that is folded to selectively attach to the handle. The pad is made of folding strip material. Furthermore, it further comprises a cleaning compound, and a water-soluble film configured to receive the pad and the cleaning compound.

Embodiments of the present invention have been made by reference, and one or more examples are shown in the drawings. Each example is provided by way of explanation of the invention and is not intended as a limitation of the invention. For example, features described or described as part of one embodiment may be used with another embodiment yielding a third embodiment. The present invention may include other modifications and variations.

As used herein, the term “meltblown fibers” is melted into a converging high speed, common hot gas (eg air) steam that thins the filaments of molten thermoplastic to reduce its diameter. By fiber or thread, it is meant a fiber of polymeric material formed by extruding molten thermoplastic through a plurality of elaborate (generally circular) die capillaries. The meltblown fibers can then be transported by high velocity gas steam and attached onto the collecting surface to form optionally dispersed meltblown fibers. Meltblown fibers can be continuous or discontinuous and are generally tacky when attached to a collecting surface. However, in some embodiments, low or minimal airflows are used to thin the fibers, and in some embodiments, adjacent threads of the molten polymer are allowed to coalesce (eg, adhere along each side of the strands of the thread). Or minimal airflow is used to at least partially join along adjacent sides of adjacent strands to form multiple threaded aggregated fibers (ie, aggregated fibers formed from two or more polymer strands as defined herein). .

As used herein, the term “celluosic” includes any material having cellulose as a significant component, in particular about 20% by weight of cellulose or cellulose derivative, more specifically about 50% by weight of cellulose or cellulose derivative. It is intended to have any material. Accordingly, cotton, common wood pulp, non-wood fibrous fiber, cellulose acetate, nitrate fiber, rayon, viscose fiber, thermomechanical wood pulp, chemical wood pulp, debondable chemical wood pulp, lyocell, and NMMO, milkweed or Bacterial cellulose, other fibers formed from cellulose in lyocells, and may be viscose, rayon, and the like. Fibers that are not processed or recycled from solution may be used exclusively if desired, or at least about 80% of the web may be free of fiber processed fibers produced from processed fibers or cellulose solutions.

As used herein, the term "flushable" generally refers to an article sized and manufactured to facilitate flushing in conventional sewage and perishable systems.

The present invention provides a toilet brush head assembly that is disposable and replaceable. 1-12 show a brush head assembly 10, which includes a brush head pad 12 and a packaging material 14 as its main components. Cleaning compounds may be added to the brush head assembly 10, for example in the packaging 14. Optional adhesive may be added to the brush head assembly 10. Details of the brush head assembly 10 are described herein.

In one embodiment of the brush head assembly 10, the sheet strip material may be folded in an accordion shape to form the pad 12, as shown in FIGS. 6 to 8. Preferably, the fold forms an edge 52. Edge 52 may lie close to the common surface such that edge 52 together form a surface when the pad is compressed in z-direction 53. The pad then takes the appearance of being formed into a straight sheet block. The pad 12 has a cleaning area 60 opposite the clamp portion 62. The cleaning area 60 is part of the pad 12 used for cleaning. The clamp portion 62 is part of the pad 12 that is clamped between the jaw 102 and the cleaning tool 100. The clamp portion 62 is separated by the cleaning region 60 in the x-direction 68 by an imaginary line.

The straight sheet block, which forms the pad 12, may have a different shape if the sheet material is cut before folding or if it changes shape after the pad 12 is die cut or formed. For example, the pad has a curved corner, in particular corner 58 (FIG. 7).

In another embodiment of the brush head assembly 10, as shown in FIG. 10, the pad 12 is comprised of sheet strip material 50 that is rolled in the direction of the longitudinal axis. This forms a cylindrical pad 12. As with the foregoing embodiment of the pad 12, there is a cleaning area 60 that is part of the pad 12 used for cleaning. The clamp region 62 is part of the pad 12 that is clamped between the jaws 102 of the cleaning tool (not shown).

In yet another embodiment of the brush head assembly 10, the pad 12 consists of a stack of separate sheets, to form a pad 12 similar to that shown in FIGS. 6 and 7 without the fold 52. It is composed. Another alternative embodiment, not shown, is to take a shorter piece of water degradable material to form a plurality of folded pieces. The separately folded pieces can then be stacked similar to that shown in FIGS. 6 and 7. Such modified embodiments may have certain advantages that can take higher manufacturing costs for zigzag or fold configuration. A single or shorter folded sheet will already be divided into a number of separate pieces, thus facilitating water degradability. Regardless of the exact embodiment, the pad is a stack that may or may not include folded edges.

Regardless of the embodiment, the entire pad 12 will stretch out or fall off after flushing (unless the user intentionally stirs the pad 12 to the toilet after dropping from the holder 100). Accordingly, it is preferable that the laminate is not bonded or free, such that the openings of the laminate are not obstructed (eg, not pressure bonded, sewn or stapled to form a compressed portion). This can potentially prevent pipe blockages before and after the brush head assembly 10 is lowered into the toilet. Before use, the pads 12 are held together by the packaging material 14. In use, the pads 12 are held together by the jaws of the handle 100.

To enhance the ability of the pad to match the radius of curvature of the toilet, the sheet or pad may be cut to form a slit 54 in the area forming the cleaning area 60 of the pad 12. The slit 54 forms a finger 56 that moves freely in all directions, allowing the finger 56 to fan out. In the embodiment shown in FIGS. 7 and 10, the slit 54 extends laterally from the cleaning edge 60 to the clamp region 62. Regardless of the embodiment used, the clamp region 62 may be sized such that no fingers 56 are disposed between the jaws 102 while using the pad 12. Preferably, the length of the finger 56 (measured in the y-direction 66) may have a width of about 2.54 cm to about 8 cm. Preferably, the fingers 56 have a width measured in the x-direction 68 of about 3 mm to about 9 mm. More preferably, the fingers have a width of about 4 mm to about 7 mm.

In the embodiment shown in FIGS. 6-8, the slits 54 can be aligned such that the cross-section of the sheet 50 between each folded edge 52 is approximately the same. After folding the pad, the fingers 56 may be approximately aligned. In addition, the pad can be perforated using a cutting technique that can pass through all layers of the pad 12.

The pad 12 can be made of various sheet materials. Most preferably, the material is structurally incorporated into pieces (preferably, multiple pieces of less than 2.54 cm for less than one day or about 30 minutes) in water, depending on the degree of mechanical agitation common in residential piping systems. It is considered to be "water degradable" which means the tendency to separate. Suitable sheet materials for pad 12 include nonwoven fibrous webs having about 90 to 100% fibrous pulp fibers.

In one embodiment of the present invention, pad 12 is formed from a sheet material having desirable abrasive properties. For example, the sheet may have an abrasive layer of meltspun webs formed using a water soluble polymeric material or melamine. In another embodiment, plastics such as microbeads, acrylic or phenols of metal, glass, carbon, mica, quartz or other minerals may be applied to the sheet material as a spray or ink. In yet another embodiment, the sheet material may have abrasive particles formed in a web of microbeads, meltblown fibers, and the like. In addition, sheet polishing may be due to uneven basis weights, uneven thicknesses, or multiple ridges due to three-dimensional topography of overlapping fibrous webs such as woven wetlaid tissue webs. It may be reinforced by recessed areas.

Preferably, pad 12 has a thickness of about 1 cm to about 3 cm. However, for some piping systems, it is more desirable to have a thickness of about 1 cm to about 2.25 cm. The number of layers of the sheet material 50 forming the pad depends on the basis weight of the sheet material 50 and the amount of compression applied to the pad 12.

1 through 5 and 9, each single brush head 12 is enclosed in a film forming the packaging material 14. The packaging material 14 may take the form of a wrap sheet (FIGS. 4 and 9) or a pouch (FIGS. 1-3 and 5). The packaging material 14 allows the consumer to manipulate the brush head within the handle device 100 without contacting any cleaning chemistry associated with the pad 12 and / or that may be contained within the packaging material 14. The packaging material 14 has a continuous or discontinuous surface that includes an opening. In addition, the packaging material 14 may be provided with an indicia as described later.

The packaging material 14 is made of water-soluble film material such as polyvinyl alcohol. Preferably, the film is polyvinyl alcohol having a hydrolysis of about 80% to about 90%, although other types of polyvinyl alcohol can be used. Preferably, the film has a thickness of about 0.7 mils to about 3 mils. As a variant, the film has a thickness of about 0.75 mils to about 2.3 mils. As another variation, the film has a thickness of about 0.75 mils to about 1.5 mils. Other water soluble films from which the packaging material 14 can be prepared include hard and soft gelatin, hydroxylpropylmethylcellulose, polyvinylpyrrolidone, sugars, sugar derivatives, starch, starch derivatives and polymerized ethylene, and polyethylene, poly Propylene, polyethylene oxide and polyethylene coacryl, or polycaprolactone. The packaging may be opaque or translucent and, if desired, dyed in color.

In one exemplary embodiment of the brush head assembly 10 shown in FIG. 1, the pad 12 is surrounded by the packaging material 14 in the form of a pouch. The pouches may be formed as tube stock, which is formed separately or as a sheet stock around the pad 12 as is known in the packaging art. Once the pad 12 is surrounded by the packaging material 14, each end 74 is sealed by heat, pressure or ultrasonic sealing device as known in the art (FIG. 12).

In another exemplary embodiment of the brush head assembly 10 shown in FIGS. 3 and 5, the pad 12 is surrounded by the packaging material 14 in the form of a heat shrinkable packaging material. In particular, the pouch can be formed by placing the pad 12 between two sheets of heat shrinkable film and then heated to conform to the pad shape as is known in the art.

In another embodiment of the brush head assembly 10 shown in FIG. 4, the pad 12 is surrounded by the packaging material 14 in the form of a sheet. The sheet is wrapped around the pad 12 so that a seam 80 is formed. A pair of flaps 82 and 84 are formed by pushing the side 86 inward toward the pad 12. Further, the flaps 82 and 84 are folded in the pad inward direction such that they overlap. The seam 80 and the flaps 82, 84 are at least partly made if they are not fully glued together, so that the packaging material 14 remains intact around the pad 12 until it is wet. Water-soluble adhesives such as casein or starch-based adhesives may be used to seal the seams 80 and flaps 82 and 84.

In another embodiment of the brush head assembly 10 (not shown), the pad 12 is only partially surrounded by the packaging material 14 in the form of a pouch or sheet. Rather than completely surrounding the pad 12 as described in the above embodiment, the clamp region 62 is left uncovered by the packaging material 14. This purpose is to prevent the packing material 14 from sticking to the cleaning handle clamp. In addition, wetting of the pad 12 can be facilitated. The open end of the partial package 14 will be adhesively connected to the pad 12. As described in the above embodiments, the cleaning compound may be disposed between the packaging material 14 and the pad 12, or permeated into the pad 12.

Regardless of the packaging embodiment, the packaging material 14 preferably surrounds the pad 12 with a friction fit to preserve the structural state of the pad 12 before being clamped in the handle 100. To accomplish this, the pad can be compressed before the packaging material 14 is applied and then inflated to achieve a friction fit. However, the packaging material 14 may be a sliding fit or a loose fit to the pad 12. This fit may be more appropriate if the pad layers are stuck together after soaking into the cleaning compound.

In one embodiment of the brush head assembly 10, the wrapper 14 has several openings 86 for the purpose of wetting the brush head 12 more quickly, thereby deteriorating the wrapper more quickly. For example, as shown in FIG. 2, an array of openings 86 may be disposed on one or more surfaces and regions of the packaging material 14. Preferably, the packaging material has a generally rounded shape and may have about 30 or more openings having a diameter or width of about 0.5 mm to about 2 mm. As a variant, the opening is a hole with a slit.

In another embodiment of the brush head assembly 10, the packaging material 14 includes a display 88 that is visible from the outside surface. The display 88 may be merely aesthetic or may be used to impart information. The indicator 88 can be printed, attached or otherwise disposed on the surface.

In some embodiments, a message, statement, or copy may be used to give information about the brush head assembly 10, and assist the user using the composition with respect to one or more mental statements, psychological statements, or well-being statements. Can be. The conversation, statement or copy may include a variety of strings, such as "clean", "fresh", "hygiene", "convenient" or "disposable" or combinations thereof, or the brush head assembly 10, in a fresh and sanitary manner. Other statements that indicate cleaning.

Another information that can be given by the display portion 88 is the jaw position. For example, an indicator (not shown) of where the user is placing the jaw 102 of the handle 100 may be disposed on an appropriate portion of the packaging material 14 that overlaps the clamping portion 62. If disposed on the outer surface 53 of the packaging material 14, the indicia may be made of ink comprising a material that prevents the jaws 102 from sticking. For example, hydrophobic inks, such as TEFLON or silicon based inks, can serve this purpose.

In another embodiment, as shown in FIG. 3, a display 88 in the form of an aesthetic design is located on the packaging 14. For example, a floral design can be used to suggest freshness. However, the present invention is not limited by this arbitrary example.

In addition, the display unit 88 may be provided as a fragrance, cleaning compound, and / or dye to color the water in the toilet bowl. For example, the dye is water soluble and can simply degrade upon exposure to water, thus transferring color to the toilet. In another embodiment, the ink in the display portion 88 may be provided with a fragrance. In addition, the ink in the display unit 88 may include a cleaning compound that is cleaned by mechanical action (polishing) or chemical action. For example, the ink may comprise abrasive materials such as metals, glass, carbon, mica, quartz or other minerals, plastics such as acrylic or phenol, or microbeads of cleaning materials such as surfactants.

In another embodiment of the brush head assembly 10, the packaging material 14 may be provided with a fragrance. For example, when the user takes the brush head assembly 10 out of the package, the film is fresh to ventilate cleaning the toilet and / or to show freshness using the brush head assembly 10 that cleans the toilet. Can be used to give a clean direction. Any indicator 88 can be used with the fragrance used. For example, a lavender flower may be represented by the display unit 88 and may be matched with a lavender fragrance 14. The fragrance may be applied to the packaging film as a separate composition, or may be embedded in the packaging film prior to extrusion.

In addition to the mechanical cleaning ability of the pad 12, it is most desirable that the cleaning compound be used with the pad 12. The cleaning compound may be a powder or particulate material, or anhydrous liquid (not to permanently decompose the packaging 14). In addition, the cleaning compounds may have antimicrobial and / or antibacterial properties. The cleaning compound may be applied to the pad 12 or the packaging material 14, disposed within the packaging material 14, or all of the foregoing. Moreover, two or more cleaning compounds can be used to treat different steps of the cleaning treatment. Each characteristic is described below.

In one embodiment of the brush head assembly 10, a highly concentrated cleaning compound is sprayed between a plurality of sections of sheet material located between the folds 52 or disposed on the outer surface 53 of the pad 12. (See FIG. 7).

Examples of cleaning compounds for such saturation or application include surfactants (eg, lauramide DEA; sodium lauryl sulfate; sodium dodecylbenzene sulfate), perfumes, and various other components such as dyes and preservatives. However, anhydrous cleaning compounds (such as chlorine bleach, oxygen bleach, enzymes, etc.) that have additional properties such as antibacterial, antimicrobial and / or anti-odor can be used. Enzymes that are water soluble proteases, such as pepsin, trypsin, pisin, bromerin, papain, rennin and mixtures thereof, can be used in particular.

In another embodiment of the present invention, the brush head assembly 10 has a powdered anhydrous liquid or particulate cleaning compound in the packaging 14 together with the pad 12. Upon storage or shipping, the cleaning compound may act in the pad 12 but is not a necessarily necessary characteristic of the cleaning compound. Preferably, the compound is prepared with an abrasive such as anionic surfactants such as dodecylbenzene sulfate, calcium or sodium carbonate, dyes, fragrances and the like. The compound may also include perborate or percarbonate to provide oxygen bleaching performance. In addition, the compounds may contain enzymes for additional soil removal capacity.

In another embodiment of the present invention, the brush head assembly 10 has a cleaning compound disposed on the inner surface (opposite surface 53) of the packaging material 14. For example, the concentrated cleaning compound may be spray coated on the interior surface of the packaging material 14.

Two or more cleaning compounds may be disposed in or on the brush head assembly 10. For example, a foamed cleaning compound may be disposed within the packaging material 14 and a colored cleaning compound may permeate between the layers forming the pad 12. Thus, in use, the brush head assembly 10 will initially be foamed after the color operation. Thus, the user will know that the pad 12 is acted upon during two stages of cleaning. In one embodiment, the first stage of cleaning may remove common bacteria and the second stage of cleaning will direct the vicinity of the toilet being cleaned.

In one embodiment of the present invention, the foamed cleaning compound may be prepared from an acid source and a carbon dioxide source. Suitable acid sources herein can provide solid organic, mineral, or inorganic acids, which are preferably in the form of acids, salts or derivatives thereof or mixtures thereof. In particular organic acids may be used. The acid will preferably be 1, 2 or 3-protonic acid. Such acids include mono or polycarboxylic acids, preferably citric acid, adipic acid, glutaric acid, cetoglutaric acid, citramalic acid, tartaric acid, maleic acid, fumaric acid, succinic acid, malonic acid. Etc. Such acids can be used in anhydrous form. Other acids include sulfonic acids such as toluenesulfonic acid. The carbon dioxide source is any substance capable of providing carbon dioxide which will react with the acid source upon contact with water. Carbon dioxide sources include carbonates, bicarbonates and percarbonate salts or mixtures thereof.

Another variant is to promote polishing by infiltrating the abrasive into the cleaning compound or by using a more abrasive material such as a mesh material. For example, in one embodiment of the invention, mesh wrap 90 may be disposed around pad 12 or brush head assembly 10 (see FIGS. 11 and 12). The mesh wrap 90 is made of a water soluble material, such as polyvinyl alcohol, or any material that can be used to form the packaging material 14. Preferably the mesh has openings 92 arranged in an array. The array may consist of a honeycomb pattern, an aesthetic design, or any pattern that forms concentric circles with heat. In the embodiment shown in FIG. 11, the opening is formed by the rib portion 94 and has a size of about 1 mm to about 4 mm. Each rib portion 94 may have a size of about 1 mm to about 3 mm. The thickness of the mesh is preferably about 1 mil to about 8 mils as measured at the thickest portion of each rib 94. In another embodiment, the thickness of the mesh is preferably about 2 mils to about 6 mils as measured at the thickest portion of each rib 94. In another embodiment, the thickness of the mesh is preferably about 3 mils to about 4 mils as measured at the thickest portion of each rib 94.

In another embodiment of the brush head assembly 10, the packaging material 14 is made of abrasive, which helps to rub bacteria from the toilet. One method of making the packaging material 14 abrasive is to impart fabric on at least an outer surface in the area covering the cleaning area 60 of the pad 12. The fabric may be a mesh material that is adhered to at least a portion of the outer surface of the packaging material 14, such as to a portion overlapping the cleaning area 60. In another embodiment, the fabric is formed by adhesively bonding a sand-like material such as sodium bicarbonate, salt, silica or pumice on the outer surface of the packaging material 14 (not shown). Any opening located through the surface 53 of the packaging material 14 may impart fabric to the packaging material 14, thereby imparting abrasive quality until the packaging material 14 disassembles.

Abrasive materials that can be added to the cleaning compound include sodium bicarbonate, silica, pumice, metals, free carbon, mica, quartz or other mineral microbeads, acrylic or phenol plastics. Preferably, the cleaning compound is a relatively coarse polymer such as ABX-30 available from Celanes. In addition, depending on the type of piping system using the brush head assembly 10, the abrasive material is preferably water soluble.

Moreover, the brush head can be changed in other ways. For example, the packaging material 14 and / or pad 12 may be BITRIX or other known bittering agent that can quickly brush the brush head assembly 10 when the children try to chew.

In operation, the foregoing exemplary embodiment of the present invention is attached to a handle, such as the handle 100 shown in FIG. The brush head assembly 10 is completely submerged in the toilet. The user may begin to rub the toilet with the brush head assembly, or wait until the packaging 14 deteriorates to further expose the pad 12. The pad 12 can be rubbed against the inside of the toilet to remove any dirt or film. After the toilet is satisfactorily cleaned, or after the pad 12 begins to degrade to the point where dirt can no longer be effectively removed, the brush head assembly 10 may be released from the handle 100. The pad 12 may easily fall into the toilet or fall into the toilet after the user has a weak hit on the handle 100. The pad 12 may be further degraded and dispersed in small pieces and flushed into the toilet. As a variant, the user may dispose of the pad 12 in the bin.

While some exemplary embodiments of the invention have been described, those skilled in the art will recognize that various modifications may be made without departing from the scope and spirit of the invention.
