TECHNICAL FIELD
The present application generally relates to cleaning systems. It relates to an apparatus for washing and cleaning reusable drinking straws.
BACKGROUND OF THE INVENTION
In bars and restaurants, many people prefer to drink beverages or drinks using a straw. Similarly, many reusable drinking vessels are provided with drinking straws. Hence, the straw plays an active role in our daily life due to its high availability. Further, if the straw is a reusable straw, then a user or business needs to clean the straw before using it again. It is difficult to clean the straw if the straw is used for a drink sticky in nature. It would be a benefit, therefore, to have a drinking straw cleaning apparatus, system, and method that could be used to clean a fluid passageway or hollow cavity of a drinking straw and the exterior straw surface.
State and local ordinances to eliminate the use of disposable or plastic straws are proliferating to improve the environment. Bar and restaurant owners are using non-disposable drinking straws manufactured principally from metal alloys safe for human use, such as stainless steel. These non-disposable drinking straws are prone to bacteriological and moisture contamination which present a challenge to maintain an inventory of sanitary non-disposable drinking straws. Most establishments are forced to use a brush to clean the inside of a metal drinking straw, and then to scour the outside of the metal drinking straw with a cleaning pad, all within a wash sink with detergent and water, and then into a sterilizing solution.
Drinking straws cleaning brushes are available in the art, and mainly include longitudinally disposed bristles. These brushes, although designed for cleaning the inner surfaces of the straws, do not effectively clean around corner ends or the external surface of the straw.
Many other variations of drinking straws cleaning brushes are found proposed in the art, such as in U.S. design Pat. D360301 and D532978. However, they are directed towards the aesthetic appearance and focus on solely the inner surfaces of straws and fail to reach tight spots, corners, or external surface in the straws for effective cleaning.
U.S. Pat. No. 6,039,490, by Banks et al., discloses a cleaning system for cleaning reusable drinking straws. The reusable drinking straw cleaning system as disclosed in the patent includes a flexible, tubular brush structure having a tubular cavity formed between a closed insertion end and an open ended, threaded squeeze bulb reservoir connecting end, several cleaning solution dispensing orifices provided along the length of the flexible tubular brush structure and several multi-length bristles extending outward from the flexible tubular brush structure.
U.S. Pat. No. 5,699,578, by Dumler et al., discloses a straw cleaning device. The cleaning device according to the disclosure includes two twisted, wire-type sections. The cleaning coming with the application of care and cleaning agents, that the wire-type sections are twisted in such a way that at least one free loop or eye is formed.
Thus, in the light of the above-mentioned background art, there is a need for drinking straws cleaning apparatus that would overcome or at least ameliorate the problems associated with existing cleaning assemblies and systems.
The above information is presented as background information only to help the reader to understand the present invention. Applicant has made no determination and makes no assertion as to whether the above might apply as prior art regarding the foregoing disclosed and claimed apparatus for washing and cleaning reusable drinking straws.
There likewise is a need for an apparatus for washing and cleaning reusable drinking straws that effectively and economically cleans the inside and the outside surfaces of the reusable drinking straw simultaneously.
There likewise is a need for a hand-held apparatus for washing and cleaning reusable drinking straws that effectively and economically cleans the inside and the outside surfaces of the reusable drinking straw simultaneously and that is inexpensive to manufacture.
There is yet another need for a hand-held apparatus for washing and cleaning reusable drinking straws that effectively and economically cleans the inside and the outside surfaces of both straight and angled drinking straws.
There is a further need for an apparatus for washing and cleaning reusable drinking straws that effectively and economically cleans the inside and the outside surfaces of the reusable drinking straw and allows for quick and easy replacement of all cleaning brushes.
There is also is a need for an apparatus for washing and cleaning reusable drinking straws that effectively and economically cleans the inside and the outside surfaces of the reusable drinking straw using upright support stand attached to the bottom of a wash sink or any other suitable planar surface.
DISCLOSURE OF INVENTION
An embodiment of the apparatus for washing and cleaning reusable drinking straws includes a hand-held handle supporting a flexible internal brush and a plurality of external brushes surrounding the internal brush. The internal brush extends beyond the plurality external brush assembly through a guide element bore. The guide element keeps the external brushes properly aligned around the internal brush while guiding the reusable drinking straw to enter the assembled plurality of external brushes through the guide element bore. A longitudinal bore through top portion of the hand-held handle surrounds the assembled plurality of external brushes. The action of moving the hand-held handle back and forth along an inserted reusable straw provides contact with the external brushes and scours the curved ends and external surface of the reusable straw. Other embodiments provide a stand assembly to adapt the hand-held handle into an upright position from the bottom of a wash sink or any other suitable planar surface embodying the apparatus for washing and cleaning reusable drinking straws.

An embodiment of the free-standing assembled reusable drinking straw wash assembly, 12, provides a central stand 102 with a central opening centered on the bottom surface (not depicted) A rubber suction cup 108 sized to be received and held by central opening centered on the central stand 102 bottom surface such that a suction cup 108 concave portion is disposed face down under the central stand 108, FIGS. 5 and 6.
An embodiment of the assembled free-standing assembled reusable drinking straw wash assembly, 12, provides a detent pin 150 having a diameter of 6.5 mm, FIGS. 5 and 6.
Thus, embodiments of the free-standing, reusable drinking straw wash tool assembly 12 can be secured to the bottom surface of a sink filled with hot water and a suitable cleaning solution. A curved reusable straw 210 or a straight reusable straw 200 is inserted onto the flexible central brush 120, FIGS. 2C and 6, into the guide element, and into the concentric external brush array in the handle element top element. As the reusable drinking straw 200 or 210 is forced along the flexible central brush 120 and through the guide element bore 56 the external brush 80 bristles contact and clean the external surface of the reusable drinking straw 200 or 210 aided by the pressure of the handle top element central bore 30 along the longitudinal axis 26 of the handle 20, FIGS. 1-2C, and 6.
The respective straw is then retracted from the respective wash tool assembly, turned around and reinserted into the wash tool assembly in the same fashion. In this manner, the entire internal surface of the reusable drinking straw and three inches of each end of the external surface of the reusable drinking straw is scrubbed and cleaned. These areas of wash tool assembly cleaning are adequate to address a user's mouth and/or saliva contact points on the reusable drinking straw. The remaining external surface of the reusable drinking between the three inches on either end is typically cleaned by methods used for silverware, such as a dishwasher.
The hand-held, reusable drinking straw wash tool assembly 10 embodiment achieves the same straw cleaning result by a user wearing rubber gloves submersing the reusable straw and assembly into a depth of hot water and cleaning solution after the straw has been inserted into the assembly in the similar manner as with the free-standing embodiment, FIGS. 1-2C.

The resilient spring distal end 592 is attached to four equal sized detents 586 spaced equally around the periphery of the circumference of the straw funnel element proximal end 584. As the straw 200 is inserted into the cylindrical straw funnel element 580 through the guide element 550 and into external brush housing element 525, the resilient spring is compressed as the cylindrical straw funnel element proximal end is extended along the guide element distal end 560 to the furthest extent. The user grips the straw distal end extending from the straw funnel element tapered distal end central opening 582 and withdraws the straw from the reusable drinking straw wash tool assembly 510. The resilient spring returns the straw funnel element to its starting position allowing the user to reinsert the other end of the uncleaned straw 200 into the cylindrical straw funnel element 580 through the guide element 550 and into external brush housing element 525. If both ends of the straw 200 have been inserted into the reusable drinking straw wash tool assembly 510 and cleaned, the next uncleaned straw 200 is inserted into the straw funnel element tapered distal end central opening 582 and the cleaning process is repeated.
An embodiment of the reusable drinking straw wash tool assembly 510 further includes a retainer collar element 570 with central opening 572 having a diameter sized to correspond to the diameter of the guide element 550, FIGS. 3 and 4, and a distal side surface having three equal sized openings 574 equally spaced about the retainer collar element central opening 572 and corresponding to the three threaded equal sized openings 534 on the external brush housing element 525 flanged surface, FIG. 9. The resilient spring proximal end 594 is attached to four equal sized detents 566 spaced equally around the periphery of the circumference of the retainer collar element central opening 572, FIGS. 12B and 16.
An embodiment of the reusable drinking straw wash tool assembly 510 also includes the guide element 550 which provides a distal end 560 sized to be received through and secured by the retainer collar element 570 and a flanged proximal end 552, a central axis 526 aligned with the handle base element longitudinal central axis 526, and a guide element central bore 556 sized to receive a drinking straw diameter, FIGS. 12B and 13. Six equal sized openings 554 are concentrically disposed around the guide element central bore 556 on the guide element flanged proximal end surface, each equal sized opening sized to receive and secure an external brush second end. The guide element central bore 556 diameter is smaller than the diameter of the external brush element central bore 530, FIGS. 11 and 12B.
An embodiment of the reusable drinking straw wash tool assembly 510 has threaded fasteners sized to be received through the two equal sized openings on the base element proximal end surface 519 and into the two equal sized external brush housing element proximal end threaded openings 521 securing the base element 524 to the external brush housing element 525, FIGS. 14 and 18.
An embodiment of the reusable drinking straw wash tool assembly 510 has threaded fasteners sized to be received through the three equal sized threaded openings in the retainer collar and threaded into the three threaded equal sized openings on the handle top element flanged surface securing the retainer element 550 and the guide element 570 to the external brush housing element 525, FIGS. 12B, 15, and 16.
For an embodiment of the reusable drinking straw wash tool assembly 510 a flexible central brush 120, FIGS. 12A, 12B, 15 and 16, is provided, having a flexible stainless-steel length, a threaded proximal end 40, and a second distal end providing a length of bristles. The flexible central brush threaded attachment threaded proximal end 40 is sized to be received by the single equal sized threaded opening 535 centered on the longitudinal central axis 526. The flexible central brush 120 can be replaced by simply unscrewing it from the reusable drinking straw wash tool assembly 510 and screwing in a new flexible central brush 120, both actions accomplished by gripping the shank of the flexible central brush 120 without disassembling the reusable drinking straw wash tool assembly 510. In embodiments of the reusable drinking straw wash tool assembly 510 the flexible central brush 120 is a 9 mm brush inside diameter—cut to a length that enables the brush bristles to reach a substantial portion of the straw 200 length. The flexible central brush 120 allows the reusable drinking straw wash tool assembly 510 to scrub and clean the inside surface of straight reusable straws 200FIGS. 2C and 6.
