referring to fig1 , a system 100 for grooming includes a handle enclosure 2 connected to a bristle holder 4 . the handle enclosure 2 is elongate , having a fore end 6 and an aft end 16 . the handle enclosure 2 is formed as a walled hollow tube or cylinder of diameter and length suitable for gripping by hand . the bristle holder 4 connectedly extends generally longitudinally from the fore end 6 of the handle enclosure 2 . the bristle holder 4 includes outwardly extending bristles 8 for brushing . for example , the bristles 8 extend from a surface 5 of the bristle holder 4 . the surface 5 may be planar , semi - spherical or other shape , of length and width as desired for numbers and placement of the bristles 8 . an end cap 14 is connected to the handle enclosure 2 at the aft end 16 opposite the bristle holder 4 . the handle enclosure 2 forms a void 10 for containing a content 12 . the content 12 can be a liquid , powder , or other composition , for example , such as a shampoo , soap , cleanser , conditioner , lotion or other . the end cap 14 securely connects to the handle enclosure 2 to prevent spillage of the content 12 contained within the void 10 of the handle enclosure 2 . the end cap 14 includes a dispenser 18 . the dispenser 18 is selectively opened to allow pouring of the content 12 contained within the void 10 of the handle enclosure 2 and closed to seal the content 12 within the void 10 of the handle enclosure 2 . the handle enclosure 2 is pliable to allow squeeze pressure to be applied by hand , to aid dispensing of the content 12 when the dispenser 18 is opened . in operation , the handle enclosure 2 is gripped by hand and the bristles 8 of the bristle holder 4 are manipulated across a surface , such as the hair and body of a pet . the void 10 contains or can be filled with the content 12 . if the content 12 is desired during cleaning or grooming , the dispenser 18 is opened and the content 12 can be poured from within the handle enclosure 2 . to prevent spillage of the content 12 from the handle enclosure 2 , the dispenser 18 is closed . the handle enclosure 2 and the bristle holder 4 of the system 100 are each manufactured by molding , extrusion , or as respective components joined in elongate manner , such as by glue , adhesive , weld , or other means . materials of the handle enclosure 2 and bristle holder 4 can include plastics , nylon , rubber , and others . the bristle holder 4 is generally fairly rigid , and can be solid in cross - section or alternately ribbed or comprised of a shell or structural elements . the bristle holder 4 may therefore alternately be formed of another material , such as wood , metal , or the like . the handle enclosure 2 is formed cylindrical in shape , with a fore end 6 and an aft end 16 . the handle enclosure 2 is generally fairly less rigid and more pliable , for example , walls of the cylindrical shape are of limited generally uniform thickness , to allow hand squeezing of the handle enclosure 2 to more readily disperse the content 12 . materials of the handle enclosure 2 return to the generally cylindrical shape when squeeze pressure is not applied . a variety of materials are possible for the bristles 8 , for example , plastic , nylon or steel filaments , natural animal or synthetic hair bristles , and others . the bristles 8 are secured to the bristle holder 4 in suitable manner , such as by glue , pad , weld , or otherwise , to prevent loss of the bristles 8 during use . referring to fig2 , a system 200 includes the handle enclosure 2 and bristle holder 4 of the system 100 of fig1 . in the system 200 , the end cap 14 is selectively removable from the handle enclosure 2 . the handle enclosure 2 is formed with a spout 20 or similar throughway to the void 10 of the handle enclosure 2 . the spout 20 includes outer screw threads 22 . the end cap 14 includes a connector segment 24 for mating with the spout 20 . the connector segment 24 includes inner mating screw threads 26 ( shown in phantom in fig2 ) for securing the end cap 14 with the spout 20 of the handle enclosure 2 . in operation , the end cap 14 is removed from the spout 20 of the handle enclosure 2 , for example , by unscrewing the inner mating screw threads 26 of the end cap 14 from the outer screw threads 22 of the handle enclosure 2 , and positioning the end cap 14 away from the spout 20 . the handle enclosure 2 is manipulated to position the spout 20 generally vertically upward , and content 12 is poured into the spout 20 to fill ( in whole or part , as desired ) the void 10 of the handle enclosure 2 . the end cap 14 is then replaced on the spout 20 and securely screwed to contain the content 12 when the dispenser 18 is closed . when dispensing of the content 12 is desired , the dispenser 18 is manually opened and the content 12 dispensed . referring to fig3 , a system 300 includes the handle enclosure 2 ( of fig1 and 2 ) filled with the content 12 , for example , a liquid or powder soap , shampoo , conditioner , lotion , cleanser or the like . the end cap 14 is connected to the handle enclosure 2 . the end cap 14 includes the dispenser 18 . the dispenser 18 is , for example , a hinged lid that snaps open and closed to cover a port 30 . in certain embodiments , a port surface 32 is formed by the end cap 14 , together with the dispenser 18 attached at an edge of the port surface 32 by a hinge 36 of the end cap 14 . the dispenser 18 includes a port stopper 34 positioned in the dispenser 18 for mating with and sealing the port 30 when the dispenser 18 , via the hinge 36 , is positioned against the port surface 32 . in operation , the hinged lid of the dispenser 18 is propped away from port surface 32 , such as by manual force . the dispenser 18 swings on the hinge 36 away from the port surface 32 , disengaging the port stopper 34 from the port 30 . thereafter , the content 12 is poured ( indicated by arrow a ) through the port 30 from the handle enclosure 2 . to aid pouring , the handle enclosure 2 , in embodiments in which the handle enclosure 2 is formed of pliable materials , may be squeezed by hand to force the content 12 from the void 10 through the port 30 . when a desired amount of the content 12 is poured , the dispenser 18 is swung on the hinge 36 back against the port surface 32 and pressed to securely engage the port stopper 34 with the port 30 . referring to fig4 and 5 , another system 400 for grooming includes the handle enclosure 2 connected to the bristle holder 4 . bristles 8 outwardly extend from the surface of the bristle holder 4 for brushing . the handle enclosure 2 is elongate , having the fore end 6 and the aft end 16 , and is formed as a walled hollow tube or cylinder of diameter and length suitable for gripping by hand and forming the void 10 for containing a content ( not shown in fig4 ). in comparison to the end cap 14 of certain other embodiments , however , a pump sprayer 44 , for example , a finger actuated mechanical pump sprayer , replaces the end cap 14 . the pump sprayer 44 includes a securement ring 47 holding an actuator 47 connected to a collection tube 49 . the actuator 47 includes a mechanical pump ( not shown in detail ) connecting the collection tube 49 to a dispersion nozzle 45 . a press end 43 of the pump sprayer 44 provides a surface for finger depression of the actuator 47 . on pressing the actuator 44 at the press end 43 , the actuator 44 is directed longitudinally a small increment towards the aft end 16 of the handle enclosure 2 within the securement ring 47 . the securement ring 47 includes internal threads 51 or other securement mechanism for removably securing the actuator 44 to the handle enclosure 2 , for example , via the spout 20 or similar throughway ( not shown ) of the handle enclosure 2 . the spout 20 can include outer screw threads 22 , and the securement ring 47 of the actuator 44 , for example , includes the inner mating screw threads 51 for attachment to the spout 20 . the actuator 44 , when attached to the spout 20 via the securement ring 47 , encloses the void of the handle enclosure 2 to prevent spillage of a content when contained within the void of the handle enclosure 2 . the content is a dispersible liquid , for example , as a shampoo , soap , cleanser , conditioner , lotion or other . in operation , the handle enclosure 2 is gripped by hand and the bristles 8 of the bristle holder 4 are manipulated across a surface , such as the hair and body of a pet . content is contained in the handle enclosure 2 , or the handle enclosure 2 can be filled with the content , and the actuator 44 is secured to the spout 20 of the handle enclosure 2 to prevent spillage of the content . if the content is desired during cleaning or grooming , the press end 43 of the actuator 44 is pressed , the actuator 44 travels an interval towards the aft end 16 within the securement ring 47 , and content is thereby pulled into and through the collection tube 49 towards the nozzle 45 and dispersed from the nozzle 45 . the actuator 44 , including the securement ring 47 , the nozzle 45 and the collection tube 49 , are each manufactured by molding , extrusion , or as respective components joined in suitable operative manner . materials can include plastics , nylon , rubber , and others . the actuator 44 is generally fairly rigid , sufficient to withstand repeated finger actuation at the press end 43 , and can include various structural , spring , and other elements , as applicable . in certain alternatives , the void of the handle enclosure can be sealed by the end cap or by the actuator , as desired . for example , the system can be provided as a unit , with both end cap and actuator , or , alternately , with only an end cap or an actuator , and the end cap may be replaced with the actuator , and vice versa , as desired by the user . in the foregoing specification , the invention has been described
