It should be understood, however that it is not intended to limit the invention to the particular forms disclosed, but on the contrary, the invention is to cover all modifications, equivalents, and alternatives falling within the spirit and the scope of the invention.
- Existing buckets (or pails) are commonplace physical containers. In a typical configuration, the bucket is cylindrical in shape having a closed bottom surface and an open top surface. In addition, buckets are often formed of low grade metal or plastic materials. As cheap materials are most often used, the resulting buckets are not very durable. In addition, their poor construction often leads to failure of the bucket at handle and other locations of the body of the bucket. Despite their ubiquity, buckets are also very limited by their lack of grip options.
- Accordingly, the embodiments of the present invention are directed to an improved container assembly that substantially obviates one or more problems due to limitations and disadvantages of the related art. Although bucket configurations are described herein, it is readily understood by one of ordinary skill in art that the embodiments of the invention may be applied to a variety of container assemblies. By improving and increasing handle locations, the bucket and its contents are more easily controlled or otherwise manipulated. Moreover, by improving the composition of its structure with the use of a multi-layered insulated core, the utility, resiliency, and longevity of buckets are enhanced.
- Turning to
FIGS. 1-3 and 8-9 , abucket 100 is illustrated according to one disclosed embodiment of the invention. In an exemplary embodiment, the bucket body havingvertical side walls 102 extending upwards from a generally flatclosed bottom 202 to form a top rim at an opening ofbucket 100. In some configurations, the top rim may be formed into alip 104 disposed around the periphery ofsidewalls 102 at the opening.Lip 104 facilitates securement of a lid 2200 (seeFIG. 22 ) to the top ofbucket 100 at the opening. Embodiments oflid 2200 may incorporate, for example, a sealable snap-on type design to affix and secure anouter rim 2202 tolip 104 ofbucket 100. The snap-on and off design allows for quick removal and replacement ofsealable lid 2200. - As shown in a
bottom perspective view 2300,FIG. 23 illustrates a receivingchannel 2302 on theunderside 2304 oflid 2200. Outer rim 2202 oflid 2200 may be urged alonglip 104 ofbucket 100 to forcelip 104 into receivingchannel 2302. In this manner,lid 2200 may be retained tobucket 100 in a sealable fashion to retain the contents therein and/or prevent the contents from spilling. In addition, the sealing action oflid 2200 tobucket 100 serves to prevent exterior materials from entering an internal area ofbucket 100 or to simply protect the contents from exterior elements. In addition,outer rim 2202 may be rigidly flexible to bend outwardly to releaselip 104 from receivingchannel 2302. - Additionally, disclosed embodiments of
lid 2200 may be configured with a built-in handle (not-shown) to make removing and re-installing the lid easier. Thus,lid 2200 may be separate and regarded as an accessory tobucket 100. In addition,lip 104 provides contouring to the edge of the opening ofbucket 100 for pouring and also provides increased strength along the edge ofbucket 100 around the periphery of the opening. Thuslip 104 facilitates the opening ofbucket 100 to maintain its shape under stress. -
Lid 2200 may serve as a seating area to the top ofbucket 100 for a user.Lid 2200 may be configured to incorporate aseating area 2204 to accommodate a user. In some embodiments,seating area 2204 may be designed as a recessed area in about the center area in the top 2210 oflid 2200.Seating area 2204 may also provide additional functionality such as serving as a table area for retaining/supporting any number and variety of items generally disposed thereon. For example, disclosed embodiments may include aninner rim 2206 along a recessed area ofseating area 2204 to generally retain and/or support the aforementioned variety of items disposed inseating area 2204.Seating area 2204 may also employ various ergonomic contours to enhance user comfort. - Additional support structure, such as spines or
reinforcement ridges 2306, may be incorporated along theunderside 2304 oflid 2200.Reinforcement ridges 2306 provide increased support to the lid to accommodate a user's weight (for example, sitting or standing) or materials set upon a top 2210 oflid 2200. In some embodiments,seating area 2204 may be configured to include anattachment area 2208, for example, configured to receive a separately applied support material (not shown), such as a cushion, for supporting a user inseating area 2204.Attachment area 2208 may employ any variety of securing means to retain the separately applied support material, such as including, but not limited to, adhesives, hook and tooth materials, screws, nails, etc. In some embodiments, a portion oflid 2200, such as recessed area ofseating area 2204, may accommodate other exemplary materials such as anon-skid pad 2400. Turning toFIG. 24 , an exemplarynon-skid pad 2400 may incorporate anon-skid design 2402, such as in atop surface 2404, to aid in traction, for example, should a user need to stand onbucket 100.Non-skid pad 2400 may also be designed having a prescribed thickness and, therefore, function as an enhancement to a user's comfort, for example, should they need to use it as a seat. - In one disclosed embodiment,
vertical side walls 102 meet in connection withclosed bottom 202 at an outerperiphery base bottom 126 ofbucket 100. Outerperiphery base bottom 126 may be curved along its outer circumference to include an arch in its ends (similar to an eggshell). Thus, this joint connection at outerperiphery base bottom 126 provides a curvature (or arch) that facilitates prevention and protection against cracking ofbucket 100 by distributing applied stresses to outerperiphery base bottom 126 over a wider area of its curved surface area and material to mitigate impacts. In one disclosed embodiment the aforementioned curvature of outerperiphery base bottom 126 is about a ⅛ inch radius. This additional layer of protection assists in a prolonged lifespan ofbucket 100. In some disclosed embodiments, abottom rim 138 of outerperiphery base bottom 126 may extend past exteriorbottom surface 200 of flatclosed bottom 202 thereby forming alip 140. The circumference oflip 140 may include a curvature profile generally extending around flatclosed bottom 202 ofbucket 100. - A
handle 106 may be attached tobucket 100 to makebucket 100 maneuverable by a user such as for handling, transporting, or manipulating the contents therein. In one disclosed embodiment, handle 106 may comprise agrip portion 112 disposed between extending arms thereby forming an integrated one-piece generally rigid design ofhandle 106. Extending arms may comprise a first extending portion 108 (extending from one respective end of grip portion 112) and a second extending portion 110 (extending from another respective end of grip portion 112). First extendingportion 108 and second extendingportion 110 may each terminate at respective attachment ends 120, as described below. In one disclosed embodiment, first extendingportion 108, second extendingportion 110 andgrip portion 112 ofhandle 106 form a generally semicircular design. It is readily appreciated that any shape or design may be formed by first extendingportion 108, second extendingportion 110 andgrip portion 112 ofhandle 106 sufficient for operating and carryingbucket 100. -
Grip portion 112 includes atop side 114 and a bottom side orunderside 116. Ergonomic features may be integrated intogrip portion 112 such as grooves, finger indents or finger receiving recesses 118 along the bottom orunderside 116 thereof. In one select embodiment,grip portion 112 comprises four grooves, finger indents or finger receiving recesses 118. The disclosed design allows a user's fingers to naturally fall into respective grooves, finger indents or finger receiving recesses 118, for example, when graspinggrip portion 112 from thetop side 114. A rounded ergonomic contour oftop surface 114 ofgrip portion 112 generally aligns with the natural curvature of a user's palm area whengrip portion 112 is grasped by a user. - A removable shoulder strap (not shown) may be attached to handle 106. In one disclosed embodiment, the shoulder strap is affixed to first extending
portion 108 and second extendingportion 110 ofhandle 106. For example, in one exemplary embodiment, first extendingportion 108 and second extendingportion 110 include clip holes for removably attaching the shoulder strap. In select embodiments, should straps may include a pad. Thus, removable shoulder strap gives the operator an additional option for transporting the bucket, for example, by carryingbucket 100 over the shoulder. - In select embodiments, each end of
handle 106 is configured to turn inwardly to terminate at attachment ends 120 ofhandle 106. Attachment ends 120 are designed as male attachment ends of an attachment plug assembly (discussed below). Thus, in a disclosed embodiment, ends ofhandle 106 may terminate in male attachment ends 120 for securinghandle 106 such as to theexterior surface 136 ofvertical sidewalls 102. As further described below, a portion of male attachment ends 120 may be disposed through theside 122 ofbucket 100. -
FIG. 3 illustrates a perspective view ofbucket 100 wherein theinterior wall 300 and aninterior bottom 302 ofbucket 100 are configured to retain the contents ofbucket 100. A complimentaryfemale receiving cap 304 is disposed in the interior ofbucket 100. As described below, a portion offemale receiving cap 304 is received throughinterior wall 300 and is designed to connect withmale attachment end 120 to securehandle 106 tobucket 100. - Turning to

Female receivingcap 304 may comprise aflanged head portion 412. A hollow extendedportion 416 projects from aninner surface 414 offlanged head portion 412 and terminates atend surface 418. Hollowextended portion 416 is configured with ahollow interior 420 for receivingmale extending portion 406. - In one disclosed embodiment,
sidewall 408 ofmale extending portion 406 is designed in a cylindrical configuration and is received within a complimentary configuration ofinterior surface 422 ofhollow interior 420. Disclosed embodiments provide the dimensions of the round cylindrical configuration ofmale extending portion 406 to be in close fit arrangement withinterior surface 422 ofhollow interior 420.End surface 410 ofmale extending portion 406 is urged towardback wall surface 426 ofhollow interior 420. An adhesive is disposed withinhollow interior 420 such that it may contact its inner region including, for example,interior surface 422 andback wall surface 426. In one disclosed embodiment, the adhesive may include 3M Scotch-Weld Plastic & Rubber Instant Adhesive PR100. However any suitable adhesive may be utilized sufficient for bonding substrates, such as EPDM (ethylene propylene diene monomer (M-class)) rubber, nylon, polypropylene and polyethylene or any low viscosity instant adhesive applications. - As
male extending portion 406 is urged withinhollow interior 420, adhesive may be applied to endsurface 410 andsidewall 408 to securemale extending portion 406 therein. A slight clearance area may exist withinhollow interior 420 such as betweensidewall 408 andinterior surface 422 and/or betweenend surface 410 andback wall surface 426 to allow for curing and to accommodate for spreading and/or expansion of the adhesive. In a final assembly,end surface 418 offemale receiving cap 304 generally abutsinner surface 404 offlange portion 402. By this arrangement, the adhesive is secured withinhollow interior 420 and does not contact any surface areas ofbucket 100. Once cured,male attachment end 120 is mated and secured tofemale receiving cap 304 whereupon handle 106 is capable of pivoting abouthole 600. Accordingly, a final handle assembly may include first extendingportion 108, second extendingportion 110,grip portion 112, male attachment ends 120, and female receiving caps 304. -
FIG. 5 illustrates analternate view 500 ofattachment plug assembly 400.Outer surface 502 is shown onflange portion 402.Outer surface 504 offlanged head portion 412 may generally resemble a mushroom shaped configuration.

In additional, other structural features may be incorporated into the design ofbucket 100 to accommodate the twist-lock connection assembly. Turning toFIG. 25 an exemplary disclosedhandle 2500 may be fashioned, designed and constructed in practically every way ashandle 106. Thus, handle 2500 may comprise agrip portion 112 disposed between extending arms thereby forming an integrated one-piece generally rigid design ofhandle 2500. Extending arms may comprise a first extending portion 108 (extending from one respective end of grip portion 112) and a second extending portion 110 (extending from another respective end of grip portion 112). First extendingportion 108 and second extendingportion 110 may each terminate at respective attachment ends, as described below. In one disclosed embodiment, first extendingportion 108, second extendingportion 110 andgrip portion 112 ofhandle 106 form a generally semicircular design. It is readily appreciated that any shape or design may be formed by first extendingportion 108, second extendingportion 110 andgrip portion 112 ofhandle 2500 sufficient for operating and carrying a bucket. - In select embodiments, each end of
handle 2500 is configured to turn inwardly to terminate at attachment ends ofhandle 2500. In this embodiment, attachment ends comprise acoupling connector 2502 of a twist-lock connection assembly. Complimentary mating retention caps may accommodate each respective coupling connector of the twist-lock connection assembly to retainhandle 2500 to a bucket as detailed below. - Turning to
FIGS. 26-28 , a twist-lock connection assembly 2600 is illustrated includingcoupling connector 2502 andmating retention cap 2602.Coupling connector 2502 may be integrally formed withhandle 2500.Coupling connector 2502 may be configured with extendingprongs 2604 configured to terminate at ahead portion 2606. In some embodiments,head portion 2606 may be configured to include an extended portion which extends beyond a width of extendingprong 2604 thereby forming a cutout area orchannel 2610 such as in an L-type configuration. Cutout area orchannel 2610 may extend along extendingprongs 2604 from aninside surface 2612 ofcoupling connector 2502flange portion 2614. Each integral extendingprong 2604 andhead portion 2606 may comprise a curvature within its design. In an exemplary embodiment, extendingprongs 2604 may project symmetrically from about a center ofinside surface 2612 offlange portion 2614. Aspace 2624 may be created between extendingprongs 2604 for accommodating a complimentary mating support structure as described below. -
Mating retention cap 2602 includes aflange portion 2616 having aninterior surface 2618. Projecting from about a center ofinterior surface 2618 is acomplimentary mating portion 2620 for accommodating integral extendingprongs 2604 andhead portion 2606 ofmale attachment end 2502.Complimentary mating portion 2620 may comprise amain support structure 2626 andextended locking portions 2630. In some embodimentsmain support structure 2626 andextended locking portions 2630 form an integral design structure.Extended locking portions 2630 may project frominterior surface 2618 offlange portion 2616 as abase portion 2628 and extending to awider head portion 2632 thereby forming complimentary cutout areas orchannels 2622 atbase portion 2628 for receiving respective extendingportions 2608 ofhead portions 2606 in mated assembly. In a disclosed embodiment, a configuration ofbase portion 2628 extends towider head portion 2630 generally forming an L-type configuration.Main support structure 2626 may generally extend from about a center ofinterior surface 2618 ofmating retention cap 2602 for extending into a complimentary shapedspace 2624 ofcoupling connector 2502 in mated assembly.Extended locking portions 2630 may comprise a curvature within its design structure. - Alternate views of
mating retention cap 2602 are illustrated inFIG. 28 . Anouter surface 2802 offlanged portion 2616 may generally resemble a mushroom shaped configuration. Anedge 2804 offlanged portion 2616 may include acurved surface 2806.Curved surface 2806 is provided to reduce stresses imparted tomating retention cap 2602 which may be transferred throughhandle 2500 by distributing externally applied forces throughout its material and against the internal side wall of the bucket. - In a final assembly,
coupling connector 2502 andmating retention cap 2602 are mated with one another by insertingcomplimentary mating portion 2620 intospace 2624. Upon mating,retention cap 2602 may be rotated into a locked position by twisting extendingclocking portions 2630 andhead portion 2632 to connect andsecure retention cap 2602 tocoupling connector 2502. In one disclosed embodiment, agroove 2808 may be provided in top side 2810outer surface 2802 ofmating retention cap 2602.Groove 2808 may be sufficiently sized to accommodate a tool, such as a flat head screwdriver, for facilitating rotation ofmating retention cap 2602. While a generally elongated channel is provide asgroove 2808, it is readily appreciated that any geometrically-designed shape forgroove 2808 may be provided (such as a hexagonal, star, Phillips tool design, etc.) sufficient for imparting rotational force to top side 2810outer surface 2802 ofmating retention cap 2602. Such rotational movement ofmating retention cap 2602 may engagehead portion 2632 into cutout area orchannel 2610 ofcoupling connector 2502. In addition,head portion 2608 is engaged within complimentary cutout areas orchannels 2622 ofmating retention cap 2602. In disclosed embodiments, cutout area orchannel 2610 ofcoupling connector 2502 is sized to close fit relation with engageshead portion 2632. Also complimentary cutout areas orchannels 2622 are sized in close fit relation withhead portion 2608. Thus, whenmating retention cap 2602 is rotated in engagement withcoupling connector 2502,head portions channels 2622 and cutout area orchannel 2610, respectively. Additional applications may also be provided to securemating retention cap 2602 tocoupling connector 2502 including, but not limited to adhesives and bonding agents. In one disclosed embodiment, the adhesive may include 3M Scotch-Weld Plastic & Rubber Instant Adhesive PR100. However any suitable adhesive may be utilized sufficient for bonding substrates, such as EPDM (ethylene propylene diene monomer (M-class)) rubber, nylon, polypropylene and polyethylene or any low viscosity instant adhesive applications. - Turning to
FIG. 29 , an exemplary embodiment of another disclosedbucket 2900 is illustrated. In some disclosed embodiments,bucket 2900 is designed to accommodatehandle 2500 and twist-lock connection assembly 2600. In many respects,bucket 2900 employees many design features as discussed in the embodiments forbucket 10, for example, includingvertical side walls 102,lip 104,exterior bottom 200, andbottom rim 138. Thus,bucket 2900 is fashioned, designed and constructed in practically every way asbucket 100. However,bucket 2900 provides additional support structure features as disclosed herein. For example, disclosed embodiments provide external areas 2902 (alongvertical walls 102 at and around hole 2904) and internal areas 2906 (alonginterior side wall 2908 at and around hole 2904) ofbucket 2900 to be made thicker in an effort to create a stronger point of connection for twist-lock connection assembly 2600 and, hence, handle, 2500 tobucket 2900. As a result,flange portion 2614 ofcoupling connector 2502 andflange portion 2616 ofmating retention cap 2602 may have an enlarged design and comprise a thicker material. The point (i.e., attachment area 2902) onvertical side wall 102 wherehandle 2500 will attach will be made thicker a similar shape (e.g., circular) of flange contact areas (e.g.,flange portion 2614 ofcoupling connector 2502 andflange portion 2616 of mating retention cap 2602) to reinforce theattachment area 2902 atvertical side wall 102 and increase the resistancevertical side wall 102 has againsthandle 2500 pulling through. In some embodiments,bucket 2900 may be configured such that from the point invertical side wall 102 where the aforementioned thickness will be increased, that thickness will carry from that point up towards the top ofbucket 2900 and taper down to meet the rim ofbucket 100. In one disclosed embodiment, the taper will follow the same degree as the overall wall ofbucket 2900 follows from top to bottom. - By connecting
coupling connector 2502 tomating retention cap 2602 throughhole 2904 invertical side walls 102, handle 2500 is attached tobucket 2900. During assembly, extendingprongs 2604 ofcoupling connector 2502 andcomplimentary mating portion 2620 are inserted through opposite sides ofhole 2904 ofbucket 2900 and mated together (as described above). The dimensions ofhole 2904 is designed in close-fit arrangement with the mated connection ofexterior surface 2634 of extendingprongs 2604 andexterior surface 2636 ofextended locking portions 2630. In one disclosed embodiment,exterior surface 2634 of extendingprongs 2604 andexterior surface 2636 ofextended locking portions 2630 are round and complimentary to the round shape ofhole 2904 to produce the aforementioned tight fit arrangement. Yet, said tight fit arrangement is sufficient to allow a mated connection ofexterior surface 2634 of extendingprongs 2604 andexterior surface 2636 to rotate withinhole 2904. - In a final arrangement, when
handle 2500 is connected tobucket 2900, insidesurface 2612 offlange portion 2614 is abutted against thickenedexterior areas 2902 ofvertical sidewall 102. Additionally,interior surface 2618 offlange portion 2616 is abutted against thickenedinterior areas 2906 ofinterior sidewall 2908.Flange 2614 ofcoupling connector 2502 andflanged portion 2616 ofmating retention cap 2602 generally prevent entry of foreign contents and loss of internal contents throughhole 2904. In addition,flange 2614 ofcoupling connector 2502 andflanged portion 2616 ofmating retention cap 2602 prevent handle 2500 from being pulled throughvertical side wall 102 ofbucket 2900. Furthermore,flange 2614 andflanged portion 2616 may act as a baffle to disallow liquid from running straight out ofhole 2900. - Turning again to
FIGS. 1-2, 8-9 and 11 ,bucket 100 may include one ormore feet 124 disposed on theexterior bottom surface 200 ofbucket 100. One ormore feet 124 may include anon-skid surface 128 on the exterior surface of the one or more feet thereby producing a one or more non-skid feet design.Non-skid surface 128 may be an integral design on the one ormore feet 124 such as being molded into the material of one or more feet 123. Thus in some disclosed embodiments, non-skid surface 12 may be integrally designed into the surface of one ormore feet 124. Alternatively,non-skid surface 128 may include a separately applied non-skid material to enhance the grip in both wet and dry conditions. The separately applied non-skid material may be removable and replaceable. Accordingly,non-skid feet 124 will serve to maintain a position ofbucket 100 such as on wet or slippery surfaces. In some embodiments, an external surface ofnon-skid feet 124 may include adesign pattern 130, such as a raised design pattern, lug or tread-like pattern. The raised design pattern, lug or thread-like patter allows liquid (such as water) to pass throughdesign pattern 130 thereby expelling the liquid from beneathnon-skid feet 124 to prevent a hydroplaning effect. Thus, thedesign pattern 130 enhances the stability ofbucket 100 in wet conditions. - In particular,
non-skid feet 124 may be configured to include an ergonomic design such as one or more grooves, finger indents or finger receiving recesses 132 to give an operator a firm comfortable grip and help control the function ofbucket 100 and its contents, for example, whether filling or emptying. In a select embodiment,non-skid feet 124 comprises four grooves or finger indents or finger receiving recesses 132. In addition,non-skid feet 124 provide ease for tasks that necessitate grabbing and manipulating the bottom of the bucket (e.g., pouring or scooping). - According to an example embodiment,
non-skid feet 124 may be mounted to exteriorbottom surface 200 ofbucket 100. In some instances,non-skid feet 124 may be detachably connected to exteriorbottom surface 200 ofbucket 100. For example,non-skid feet 124 may be mounted and secured via connectors such as with ¼ inch marine grade stainless steel screws. In another embodiment, a connecting assembly, such as marine grade stainless steel bolts and nuts, may be utilized to securenon-skid feet 124 to exteriorbottom surface 200 ofbucket 100. In another disclosed embodiment,non-skid feet 124 may be secured to exteriorbottom surface 200 ofbucket 100 by an adhesive. In one disclosed embodiment, the adhesive may include 3M Scotch-Weld Plastic & Rubber Instant Adhesive PR100. However any suitable adhesive may be utilized sufficient for bonding substrates, such as EPDM (ethylene propylene diene monomer (M-class)) rubber, nylon, polypropylene and polyethylene or any low viscosity instant adhesive applications. It is also readily appreciated that any other connection device or method may be utilized to detachably connect one or morenon-skid feet 124 to exteriorbottom surface 200 ofbucket 100. In one disclosed embodiment,non-skid feet 124 are mounted such that the grooves or finger indents or finger receiving recesses 132 face towards the center ofbucket 100. A contour of thebackside 142 ofnon-skid feet 124 may be generally designed to match the same contour of the circumference of the outer edge of flatclosed bottom 202 and/orbottom rim 138. - In some disclosed embodiments, a thickness of
non-skid feet 124 may protrude or extend pastbottom rim 138 of outerperiphery base bottom 126. For example, in select embodiments,non-skid feet 124 may protrude a short distance (e.g., about ⅛ inch), and have an overall thickness (e.g., about ⅜ of an inch). Given thatnon-skid feet 124 extendpast bottom 202,non-skid feet 124 may serve as a buffer from impacts, since any contact belowbucket 100 will generally occur tonon-skid feet 124 before reaching exteriorbottom surface 200 ofbucket 100, for example, whenbucket 100 is dropped. Accordingly, sincebucket 100 is elevated having been mounted to one or morenon-skid feet 124, as a primary point of contact, one or morenon-skid feet 124 may wear more quickly thanbucket 100 itself. - In select embodiments,
non-skid feet 124 are removable and replaceable thereby extending the wear-life ofbucket 100.Non-skid feet 124 may vary in overall length (e.g., about 4 inches). In other configurations,non-skid feet 124 may be integrally formed as part ofbucket 100. Disclosed embodiments provide placement ofnon-skid feet 124 along exteriorbottom surface 200 in a symmetrical manner such that twonon-skid feet 124 generally align with the front and back ofbucket 100, respectively, and twonon-skid feet 124 generally align with each side (left and right) ofbucket 100, respectively. Thus, at least twonon-skid feet 124 are generally mounted in the swinging direction ofhandle non-skid feet 124 may be mounted perpendicular to the other twonon-skid feet 124 mounted in the swinging direction ofhandle - Skilled artisans will readily appreciate that more or less
non-skid feet 124 may be applied and mounted to exteriorbottom surface 200 ofbucket 100 accordingly to individual design preferences. Recognizing that the utilization of any quantity/alternative number ofnon-skid feet 124 will generally depend on providing a preferred stability and protection forbucket 100, alternative non-skid feet configurations may be achieved. For example, turning toFIG. 12 , thenon-skid foot 1200 is configured as a one-piece foot design 1202. A contour of thebackside 1202 ofnon-skid feet 1200 may be generally designed to match the same contour of the circumference of the outer edge of flatclosed bottom 202 and/orbottom rim 138. Like the previously describednon-skid feet 124,non-skid foot 1200 may incorporate a non-skid surface 128 (including, for example, a raised design pattern) on its exterior surface and be secured in a similar fashion to exteriorbottom surface 200 ofbucket 100. In an alternative configuration,non-skid foot 1200 may be integrally formed as part ofbucket 100. As withnon-skid feet 124,non-skid foot 1200 may be similarly replaceable, for example, after extended wear or damage. - In another embodiment,
FIG. 13 illustratesnon-skid feet 1300 as a two-piece foot design 1302. A contour of thebackside 1304 ofnon-skid feet 1300 may be generally designed to match the same contour of the circumference of the outer edge of flatclosed bottom 202 and/orbottom rim 138. Like the previously describednon-skid feet 124,non-skid feet 1300 may incorporate a non-skid surface 128 (including, for example, a raised design pattern) on its exterior surface and be secured in a similar fashion to exteriorbottom surface 200 ofbucket 100. In an alternative configuration,non-skid feet 1300 may be integrally formed as part ofbucket 100. As withnon-skid feet 124,non-skid feet 1300 may be similarly replaceable, for example, after extended wear or damage. -
FIG. 14 illustrates a configuration where less non-skid feet are utilized along thebottom 202 ofbucket 100. Nevertheless, the non-skid feet are placed generally at equal distances from one another to provide stability tobucket 100 and protection to exteriorbottom surface 200. Accordingly,non-skid feet 1400 are disposed around the circumference of exteriorbottom surface 200 orbottom rim 138 as a three-piece foot design. It is readily appreciated that previously discussednon-skid feet 124 may serve asnon-skid feet 1400, and hence,non-skid feet 1300 may incorporate a non-skid surface 128 (including, for example, a raised design pattern) on its exterior surface and be secured in a similar fashion to exteriorbottom surface 200 ofbucket 100. In an alternative configuration,non-skid feet 1400 may be integrally formed as part ofbucket 100. As withnon-skid feet 124,non-skid feet 1400 may be similarly replaceable, for example, after extended wear or damage. -
FIGS. 15-20 illustrate another embodiment of the disclosed bucket. In an alternate embodiment, construction of the bucket body (i.e.,vertical side walls 102 extending upwards from a generally flatclosed bottom 202 to form a top rim at an opening) ofbucket 1500 is similar in every way tobucket 100, however, the alternate embodiment ofbucket 1500 includes one or more side handles 1518 introduced and mounted toexterior surface 136 ofvertical sidewalls 102. In some embodiments, one or more side handles 1518 is detachably connected tovertical walls 102. One or more side handles 1518 may be disposed on the front and back ofbucket 1500, i.e., generally half way between the mounted locations of attachment ends 120 and in the swinging directions ofhandle 106. Mounted tobucket 1500 in this manner, one or more side handles 1518 facilitate handling and control ofbucket 1500 during operation or manipulation thereby creating an improved handle configuration. - In some instances, one or more side handles 1518 include a two-in-one handle configuration including a
rigid side handle 1504 andnon-rigid side handle 1506. Non-rigid side handle 1506 may include arope 1508 and rope handle orgrip 1512. In a disclosed embodiment, each end ofrigid side handle 1504 may include a thru-hole designed to accommodate rope 1508 (e.g., about ¼ inch rope).Knots 1510 may be tied to securerope 1508 through locations of rigid side handle 1504 to retain non-rigid side handle 1506 thereto. Rigid side handle 1504 may be detachably connected toside walls 102 ofbucket 1500 via one or more connectors 1514 (such as with marine grade stainless steel screws, marine grade stainless steel bolt and nut assembly, adhesive, or any other appropriate securement device sufficient to retain one or more side handles 1518 to vertical wall 102). - Rigid side handle 1504 may include an ergonomic design such as being outfitted with grooves, finger indents or finger receiving recesses 1516 on the bottom side
rigid side handle 1504 thereby forming a rigid grip for added control and manipulation ofbucket 1500.Top surface 1502 ofrigid side handle 1504 may employ an ergonomic design to accommodate a natural curvature of a user's palm. In one select embodiment,rigid side handle 1504 comprises four grooves, finger indents or finger receiving recesses 1516. The disclosed design allows a user's fingers to naturally fall into respective grooves, finger indents or finger receiving recesses 1516, for example, when grasping rigid side handle 1504 fromtop surface 1502. Thus, disclosed embodiments provide one or more side handles 1518 and/or one or morenon-skid feet 124 disposed on the bottom surface of the bucket. In an exemplary embodiment, one or morenon-skid feet 124 are aligned directly below one or more side handles 1518.Bucket 1500 and its contents can be controlled or otherwise manipulated using the two-in-one handle configuration disposed along the bucket's sides (for example, including grooves, finger indents orfinger receiving recesses 1516 or rope handle or grip 1512) as well as handle 106 ornon-skid feet 124. - In some embodiments, the two-in-one handle may have an overall length of about five inches, and may protrude from the side of bucket 1500 (e.g., by about ¾ inches). Despite such protrusions, rigid side handles 1504 may be integrally formed as an actual part of bucket 1500 (e.g., built into the mold).
- Construction and Materials
- Disclosed embodiments provide an improved bucket with handle as a performance product superior in materials and functionality that's visually pleasing and minimalist in its appeal. Disclosed embodiments for

FIG. 21 illustrates tensile modulus versus temperature for Zytel® ST801AW NC010. - It is readily appreciated that the selection of materials is not limited to Zytel® and that any suitable engineered resin designed to be light weight and super tough with excellent impact resistance, hot and cold temperature resilience, good electrical and flammability properties, good abrasion and chemical resistance, BPA free and good UV stabilization for forming the aforementioned components of the disclosed invention may be utilized.
- Materials selection for
non-skid feet 124 may comprise a second material. In select embodiments, the second material may include Santoprene™. Thus,non-skid feet 124 may be formed by injection molding. It is readily appreciated that the selection of materials is not limited to Santoprene™ and that any rubber material compound may be utilized for generating the over-all shape ofnon-skid feet 124 including design pattern 130 (such as a raised design pattern, lug or tread-like pattern) sufficient for providing/achieving high-performance grip and traction in accordance with the disclosed invention. Several colors fornon-skid feet 124 may be available to enable customization ofbucket - Thus, the embodiments of the present invention can dramatically enhance the control that a user has over
bucket - From the
point bucket grip portion 112 inhandle grip portion 112. Accordingly, the user has an increased sense of control and comfort, for example, when filling or pouring out the contents ofbucket non-skid feet 124. This equates to less exertion by the operator and minimizes the risk of the contents and/orbucket bucket vertical sidewalls 102 which may be subtle, i.e., virtually unnoticeable. The resulting look conveys clean lines that echo a more refined approach to performance utilization. - It will be apparent to those skilled in the art that various modifications and variations can be made in the improved insulating container of the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
- Multi-Layer Structure
- Buckets according to another example embodiment of the present invention may be formed to include a multi-layered insulated core. In addition to improving the utility, resiliency, and longevity of the bucket, the multi-layered insulated core may increase the utility of the vessel by allowing it to retain ice and double as a cooler. Other disclosed aspects include the bucket's ability to retain heat such as for heated foods and/or beverages.
- Accordingly to an exemplary disclosed embodiment, the interior and exterior of the lid and body of the bucket may be constructed using a process of biaxial rotomolding using a base of medium density powdered polyethylene with ultra-violet inhibitors. For example, both the interior and exterior wall of the bucket may be ⅛ inch thick. The middle layer or core of the bucket may be made of a variety of insulating materials, such as PUR in-situ foam or polyurethane foam. The insulating material may be sprayed or otherwise deposited into the void created between the interior and exterior two rigid layers of polyethylene with ultra-violet inhibitors. In some instances, the insulating layer may be ¼ inch thick, and deposited to have a seamless structure.
- Molding Aspects
- According to some embodiments of the present invention, a mold for the bucket used in the rotomolding machine may include appropriate locations for aluminum bar handle anchor points as well as the two-in-one rope side handle anchor points. The anchor points of the non-skid feet may be located in the mold as this is where they would be attached to the bucket bottom. The resulting bucket body and lid may then be constructed accordingly with the handle attachments, non-skid feet, sealable lid, and the removable shoulder strap. The body and lid of the bucket may be constructed via a process of biaxial rotomolding. The roto-molded multi-layered insulated core body may fixed with the aluminum bar handle with grips on opposing sides of the bucket. The two-in-one rope side handles with finger indents grip may also be affixed on opposing sides of the bucket. The non-skid feet with finger indents may also be affixed on the bottom of the bucket in various configurations. The sealable multi-layered insulated core lid can be affixed to the top of the roto-molded bucket body. An aluminum bar handle with grip portion may be constructed and attached to the bucket. A shoulder strap can be attached, for example, to clip holes on the aluminum bar handle with grip portion.
- Additional Aspects
- The embodiments of the present invention are unique as the change in the composition of the body of the bucket to a multi-layered insulated core construction creates unmatched strength and longevity and opens up a new realm of utility previously unseen such as by creating the ability to retain ice and double its use as a cooler.
- The invention described here drastically increases the life and effectiveness of the bucket by using materials that make the body of the bucket exponentially stronger and easier to use. The handle systems not only accommodate the weight of whatever the operator wants to fill the bucket with, but also give the user several different options for increased control as different materials and situations often call for. The non-skid feet prevent the bucket from sliding away from where it is placed and the attachable lid prevents the contents from spilling and enhances the insulation qualities of the vessel. The result is a well-made product with increased functionality and a longer life.
- While the present invention has been disclosed with references to certain embodiments, numerous modification, alterations, and changes to the described embodiments are possible without departing from the sphere and scope of the present invention, as defined in the appended claims. Accordingly, it is intended that the present invention not be limited to the described embodiments, but that it has the full scope defined by the language of the following claims, and equivalents thereof.
