Definitions

  • the present disclosure relates generally to a device and system for preventing accidental splashing or spilling of sloshing liquid from a sip-hole on a container or its lid. More specifically, to a sip-hole extension insert device for preventing accidental beverage spills or splashes from the open sip-hole on beverage containers and their lids; certain embodiments combine a tear- off and or removable plug combination to further limit liquid flow.
  • Applications include containers or their lids such as those found on coffee cups at retail outlets such as Starbucks, 7/11 , and Dunkin Donuts for hot or cold liquids. Additional applications of the invention also include containers, lids, liquids, and soups that are heated and often reheated multiple times, or reused.
  • sip-hole plugs or stoppers are costly, terrible for the environment, you need two hands to operate it, but worst of all, they prevent a person from enjoying their beverage until the plug is removed. For a driver this could have catastrophic results, because this means taking both hands off the steering wheel to begin this process.
  • a smart driver might use only one hand to remove the plug, and then place it down somewhere else in their car where it might stain the car. At that point, the sip-hole is open again, and accidental spillage is very likely outcome. Other then consumption-less transport, the plug is not the best solution.
  • a container, a !id, or its sip-hole as one might normally do while adding the ability to suck the liquid through an added flow-path thereby increasing the flow of liquid for better, or more controlled consumption.

  • Sip-tubes can vary in size, shape, and design, but in use they achieve similar benefits.
  • Some sip-tubes are simple hollow tubes that are designed to be secured to a sip-hole found on a container, or its lids, in efforts to extend the sip-hole.
  • the sip-tube-plug combination device not only extends the sip-hole of container or a lid, but it can also be used to plug the sip-hole when desired.
  • the extended sip-hole, or sip-tube works by deflecting sloshing liquid, and directing the flow of liquid in a controlled and desired manner within its hollow flow-path, thereby limiting or thwarting undesirable or "accidental spill and splash" of liquid, aka “ASSL", for short reference.
  • a sip-tube works be deflecting the sloshing liquid within the container when it's jostled, and by controlling the amount of liquid within the flow-path along with its direction and rate of flow, it also lessens the force excerpted by the sloshing liquid in the container on the liquid after it enters the flow-path, thereby minimizing or preventing accidental spill and slash.
  • the combination of the sip-tube and plug can eliminate all ASSL when the sip- tube-plug combo insert device is in a folded/closed position, such as that illustrated in FIG. 6, 16 and FIG. 19.
  • sip-tube-plug in conjunction with a container or lid are, but not limited to;
  • sip holes Lessens or eliminates accidental spill and splash (ASSL) from sip holes. Adds suction ability to sip holes, which can increase liquid flow when desired. Widens sip holes for faster consumption.
  • ASSL accidental spill and splash
  • Blocks dissipation of hot steam liquid which helps maintain heat longer while consuming hot liquids; thereby conserving desired temperatures, hot or cold.
  • FIG. 2 is a tilted front to back view of a similar embodiment from FIG. 1, it illustrates the extended sip-hole which protrudes in a downward direction, while plug element 30 is illustrated in FIG. 3, which protrudes in an upward direction.
  • the insertion of plug element 30 into the hollow sip-tube or flow- path 01a as seen in FIG. 10 and FIG. 11 shows how the sip-tube is folded and set into a closed position. Once the plug is fully inserted into the hollow sip-tube as illustrated in FIG. 6, 7, 15, and FIG. 18, this becomes the folded and or closed position. This folded/closed position is used to eliminate and block, or plug ail ASSL.
  • the plug could be designed to fit snugly in a secured position with the sip-tube.
  • An additional extended protrusion 02b as illustrated on plug 30 in FIG. 3 and FIG. 10, can help to secure and seal the plug within the sip-tube.
  • FIG. 17 through FIG. 21 illustrates a similar plug example, except with a slide plug 30b design instead of a fold plug 30 design.
  • FIG. 19 and FIG. 20 show the slide plug 30b, in the closed position.
  • FIG. 20 illustrates plug 30b in the open position.
  • the slide plug is operated by sliding it forward or backwards, from the open position to allow liquid to flow through the sip-tube, to the closed position that plugs the sip-tube to block all ASSL.
  • the closed position is preferred to extend off the front of the sip-tube, this way it could be slid to the open position with the mouth.
  • a slightly elevated edge can be formed on the front and backside of the slide plug, to secure it in place, and to have something to grab on to with the fingers, or mouth.
  • FIG. 3 is a side view of similar embodiment from FIG. 1 , it illustrates a tubular shaped sip-tube 01 which comprises the main body of the sip-tube, it can be seen clearly on FIG.'s 1 through FIG. 21.
  • the hollow tubular aspect 01 a or flow-path can be seen on the topside and bottom side of FIG. 2.
  • This hollow tubular aspect, or flow-path 01 a is better illustrated in FIG's 4, 5, 10, 14, 20 and FIG. 21.
  • These sip-tubes and flow-path's are designed to be secured to, and seal a sip-hole found on a container, or its lid, and then extend the sip- hole along a guided flow-path. Liquid can then flow through the hollow extended sip-hole, along the flow-path, in a more controlled and directed fashion.
  • Some of the flow-paths as seen in most of the FIG.'s, with the exception of FIG. 5, 17, 18, 19, 20, and FIG. 21 are single path sip-tubes. Sip-tubes and their flow-paths help to deflect sloshing liquid from accidentally splashing out from a sip-hole.
  • FIG.'s 5 has one angle 03 formed along its path.
  • FIG's. 17 thru FIG. 21 have more then multiple angle 03 formed along their flow-paths. These angles create a labyrinth of flow-paths each designed to further deflect sloshing liquids. By directing liquid through two or more angled flow-paths, in opposing directions, it forces the liquid into a desired and controlled flow direction and rate. These additional angles help the further deflect and control liquid flow and rate.
  • angles serve other functions as well; first it helps to lessen the accidental or undesirable sloshing and splashing of liquid flow in an upward direction, and in a forward/backward direction by blocking and redirecting multiple slosh directions into a controlled and desirable direction, they give the liquid more space to settle before it can exit the container, and they deflect the liquid back at itself before it ever enters the sip-tube.
  • the triple angle such as that one FIG. 17 deflects sloshing liquid multiple times by the time it reaches the exit point on the topside of the sip-tube.
  • a flow-path formed in two or more opposing directions works incredibly well because it forces the liquid to travel in the opposite direction it did from the previous angle, this kind of reverse angle sip-tube can
  • FIG. 3 and FIG. 14 do not have multiple angles formed in their flow-paths, but they are angle formed 29 flow-paths.
  • This single formed angled flow-path performs the same functions mentioned above, but does so in a simpler way, and these single angle designs can be manufactured by a broader range of processes, some that could be cheaper to produce then a multiple angled flow-path.
  • Some embodiments such as those illustrated in FIG. 14 can be designed to rest just along the inside of a container or its lid after being secured to its sip-hole, and then limits to allow the desired flow rate to enter the flow-path through the cutout space between the container wall and the sip-tube. This design often works well for helping control ASSL.
  • the flow-path sip-tube deflection process further benefits when accompanied by a secondary exterior base angle 07, as seen in FIG. 5, 11 , 12, and FIG. 17, formed at the exterior bottom side opening of the hollow flow-path.
  • the base opening angle on the flow-path aides by further deflecting sloshing liquid before it ever enters the sip-tube. It also helps to guide liquid into the flow- path as the beverage container empties or the cup tilts. The slightest difference in this base angle might add some advantages in liquid sloshing in one direction, however it might lessen other advantages gained by the flow- path of sloshing liquids in other directions.
  • the preferred angle varies with size of the bottom opening hole and the number of angles along the flow- paths. The angle is not necessary, however it can be beneficial in some embodiments. It also aids and helps when trying to access all liquids within the container when pouring it and draining it. This exterior angle also aides in SIP-HOLE IMPROVEMENT
  • FIG. 11 and FIG 12 illustrates a double base angle 07, separated by a single exterior base side viscosity barrier 05. This double base angle combined with viscosity barrier 05 slows down sloshing liquid and channels it into a controlled and desired flow.
  • FIG. 3 illustrates a downward-curved base 23, this base works well in redirecting liquid.
  • a base that works particularly well, but that is not illustrated is the opposite base of 23, it curves in an upwards direction.
  • a double curved base works well at deflecting liquid and makes for easy draining of liquid entering the sip-tube.
  • These curved bases perform a similar function as the angles in a flow-path do. They force liquid to be redirected in a controlled fashion, before allowing it to enter the sip-tube, this helps with ASSL.
  • sip-tube extension adds a suction like ability much like that of a mini-straw or sippy-cup to any basic cup/container once it is inserted. This ability helps in many ways, some of the more notable ones pertain to safety.
  • a sip-tube a person would no longer need to tilt the cup so they can take a sip.
  • Standard coffee cups and lids will block your line of site when tilting them to take a sip, this can be dangerous while incredibly aggravating. Standard paper cups leak from the cup-crease when the cup is tilted.
  • sip-tube can also be formed to widen or stretch the hole it is inserted into, this helps to increase the flow of liquid whether pouring, sucking or sipping.
  • This widening or stretching can be accomplished in several ways.
  • One of the more obvious ways is by forming the sip-tube with a taper 04 as seen in FIG. 2, 11 and FIG 18.
  • the taper design 04 helps with the insertion and sizing process. By constructing a sip-tube with a smaller base then any hole it might inserted into, this allows for easy insertion no matter what shape or size a sip-hole might be. It can thereby stretch a differently shaped sip- hole to conform to the shape and size of the sip-tube that is inserted, or vice- versa.
  • FIG.'s 1 through FIG. 21 show a version of protruding extension 02, also called safety locking element 02d as seen in FIG. 10.
  • 02a, 02b and 02c are subseries of 02, they are illustrated on most of the figures with slight modifications from 02. These elements work to secure a sip-tube in a snug, and proper functioning position within the sip-hole of the container or lid it is placed into.
  • 08c and 08d extended arm as illustrated on FIG's. 4, 7 and FIG. 10, are extended topside ramifications or versions of locking protrusion 02 and its subsets. These extended protrusions add several benefits, including a layer of safety in the prevention of chocking. They also ensure a more snug fit, seal and positioning of a sip-tube with a sip-hole. 08, 08a and 08b extend surface area where lips might come in contact with a lid, a container, or the sip-tube itself, thereby completing a closed loop seal for a good suction sip- tube insert device.
  • An extended arm could be designed with a slightly curved shape 38 on FIG. 18 at the topside of its sip-tube, to match the shape of a person's lips.
  • an adhesive agent can be applied to the underside of any 08, or the topside of any 02 or their subseries, to allow them to be more securely attached for positioning and safety, or permanently adhered to a container or lid.
  • the adhesive agent can consist of any standard or specialized agents, but preferably it would be made from edible
  • FIG. 4 Another means for attaching the insert to a container or lid is illustrated in FIG. 4 as female lock cutout window 28.
  • female lock cutout window 28 This can be any size or shaped latch and groove cutout, or any other type cutout insert lock mechanism used for situations like this. Whether its female or male, it makes no difference, as long as the container or lid is formed to receive it.
  • This feature could be combined with 02 or 08 to fit snugly along the rim or edge of a container or its lid, thereby further securing it in position and forming a snug seal.
  • this mechanism could be formed on an accompanying container or lid for attachment after manufacture of each component separately.
  • Each element should be constructed to prevent accidental release that could result in a person choking or ingesting the sip-tube. These additional elements are not necessary but they do add secondary levels of safety and SIP-HOLE IMPROVEMENT
  • FIG. 6 illustrates a sip-tube-plug engaged in its folded/closed position, with window cutout 28 having a secondary use that allows advertising/branding aspect 19 to show on the sip-tube-plug whether it is in its open or closed position.
  • 19 could be formed in a lifted or embossed and raised fashion so that it sits flush or extends beyond cutout 28 when the sip-tube-plug is in its folded/closed position.
  • FIG 9 illustrates finger-grab cutout 25. This shape and size can be altered to fit any size extension arm. This feature helps to cut back on material, costs and allows for easy handling.
  • finger lift 26. 26 adds an easy to grab latch to lift the sip-tube out from the sip-hole. 08 and its subseries can work as a grab latch as well. Crease fold 22 can be added to extension arm 08 subseries, this crease will help to allow an easy fold as illustrated in FIG. 7.
  • sip-tube extension insert seals the sip-hope, blocking the largest hole where heat escapes from. Therefore it works to keep the liquid inside the container, hot or cold, at its desired temperature for a longer period of time.
  • FIG. 10 and FIG. 11 illustrate viscosity barrier 05.
  • 05 is an example of an external viscosity barrier. This barrier adds a filter-like feature that breaks up sloshing liquid and makes it harder for liquid to unintentionally enter the flow- path. The more viscous the liquid, the more deflection force is applied on the sloshing liquid.
  • 05a as seen in FIG. 5 is an example of an internal viscosity barrier. This internal barrier works and performs the same function as an external one.
  • a viscosity barrier is formed as both an exterior and interior barrier, running the full length of the flow-path, from the base opening to the top opening. Internal viscosity barriers such as 05a create channels or cambers. These chambers constrict the passage of liquid and help to better control liquid flow and direction.
  • barriers of different shapes and sizes can be formed outside or inside a sip-tube to increase these benefits.
  • Many barriers can be combined to form a screen-like membrane that liquid can pass through. This screen-like membrane can further deflect sloshing liquids. These viscosity barriers push against the viscous forces of liquids, further deflecting sloshing liquids and making it harder for unintentional liquids to escape from the topside of the sip- tube. The more of these barriers added, the better they deflect liquids.
  • the angle of the barrier, direction they run, thickness, number placement of the barrier within or on the flow-path, and space between the inner walls of the cambers and flow-path are all important when considering desired flow control SIP-HOLE IMPROVEMENT
  • barriers can also be used as a support structure when using weaker, softer or edible materials when constructing a sip-tube.
  • FIG. 4, 6 and FIG. 18 illustrates the vented hole 06.
  • the vented hole serves several notable purposes but is not limited to these; first it allows more liquid to flow into the flow-path for faster pour and suction, second it allows for cross flow of liquid which also aids in this but also deflects liquid, third it allows equal liquid flow distribution, forth it serves as an air hole for better liquid flow and pour.
  • the difference in sizing, number of vented holes and position of these vented holes can further increase some of the benefits mentioned, and can add some additional flow and deflection benefits.
  • the base side opening of a sip-tube can be designed to be smaller then sip-hole it will be placed in, but still allow for the same, or more liquid to enter the flow-path.
  • a good spot for placement of a vented hole is on the top side of sip-tube, situated between the wall of container, and the sip-tube, this is helpful when pouring out every last drop of liquid held in the container.
  • the inner flow-path of FIG. 5 and FIG. 10 have an interior protrusion 10 that can be seen in the cross-section view.
  • This serves as a splashguard to deflect upward sloshing liquids within the flow-path.
  • these protrusions could be beneficial along the inner flow-path of a sip-tube. They can be placed in multiple areas, sized and shaped in various configurations to deflect upward sloshing liquid. This element might be hard to manufacture using certain processes. Other methods would lend better to forming this feature.
  • topside flow-path extension Another feature to mention, which is not illustrated in the drawings, is a topside flow-path extension. Meaning the flow-path does not lay flush upon the sip-hole, container, or the topside of the sip-tube, as most of the illustrated versions do. It would extend the flow-path outwardly and above to topside. This could make for easier drinking, pouring, or sucking. It could also aide to improve the flow-path benefits and prevent additional splashing. This could also be used to aide in removing the sip-tube later, be it for recycling purposes or otherwise.
  • sip-tube can be packaged and stacked 20 on top itself, as illustrated in FIG. 8 and FIG. 12.
  • Some embodiments could be stacked together much like cup lids are, or post- it notes are.
  • Some embodiments could even use adhesives that could be used to secure them so they could be easily stacked for retail usage.
  • FIG. 13, 14, 15 and FIG. 16 illustrate a sip-tube inserted into the sip-hole of beverage lid 39.
  • the sip-tube can be designed and inserted to fit any container sip-hole, or lid. It would work well with box beverages and could be used to replace the common straw with a cheaper and eco-friendly solution.
  • a sip-tube-plug is used by inserting it into a sip-hole found on a container or a lid. After insertion, a sip-tube can be pushed or pressed into proper position. 02 locking protrusions and 08 extension arm and resting zone 18 will lock the SIP-HOLE IMPROVEMENT
  • sip-tube in place within the sip-hole, they will also help form a tight leak proof seal.
  • the sip-hole will then be extended to the length of the sip-tube, the sip-hole with be enhanced, and the benefits discussed within this application will be achieved.
  • the extension arm 08 could be folded and plug 30 could be locked within the sip-tube 01.
  • slide plug 30b could be slid from the open position to the closed position at will to seal the sip-tube. Overall, this will make for a happier, more controlled and better splash-free drinking experience, while also being more economical and eco-friendly solution to the common spill-plug, or splash-stick.
  • a plug would be constructed as a pull or tear off seal, similar to those on beverage containers.
  • Materials can be of any plastic, metal, polymer, paper, or the like of any known seals used by those trained in the art.
  • the seal can be bonded, attached, adhered, glued, heat sealed, heat-bonded, built in mold, as few general options. This peel or pull off tab would be a most economical solution, while also adding a level and sanitary comfort while pressing the insert tube in place within the sip-hole.
  • Flow-paths are referenced many times within this applications, they can be found inside a tube, and can sometimes mean the outside of a tube.
  • Flanges is used with the claims section, and often refers to its traditional meaning, but also any bevel, lip, protrusion in or out.
  • Inlets are referenced in the claims, they are used with their general meaning, but also used to reference a configured cut, hole, opening, used to control or limit liquid and gas flow, in and out of the tube is found on. They will generally be found on the front side of many embodiments, but can have more then one, and also be found on the back side, and bottoms of the tube.
  • Sip-hole-plug extension can be constructed using partially or fully edible materials that could be eaten, dissolved into for flavoring, or pushed into drinks for flavor. This would cutback on waste and would add a nice flavor option to the sip-tube. Many materials would work for this, but a hard crystalline sugar or coating might be a good example. Other materials include paper, cardboard, plastics, polymers, compounds, mixtures and various combinations for these. Standard materials used in the container, cup, utensil and lid industries would work well. Manufacturing processes include those used by these industries as well, but no limited to these. The sip-tube could be extruded, formed, cast, press, cut, molded, to name a few common methods.
  • sip-tube and slide plug element would likely be manufactured separately, then assembled. There are some known methods that could be used to manufacture both pieces at the same time, without the need for assembly. Newer scented materials have become popular in the beverage industry as of late. The sip-tube-plug would farewell being designed from a flavored, and or scented material. Visual

Abstract

La présente invention concerne un dispositif d'insertion, un procédé et un système pouvant empêcher le déversement et la projection de liquides en ballottement à travers le trou d'aspiration d'un récipient et/ou le trou d'aspiration d'un couvercle, mais permet toujours au liquide de passer à travers le trou d'aspiration. Ceci est réalisé en créant un dispositif à tube ou à trajet d'écoulement tubulaire ou à trajet d'écoulement en labyrinthe, avec une entrée, et une bride qui pourrait être fixée à un trou d'aspiration dans des efforts pour diriger et contrôler l'écoulement et le débit de liquide à partir de l'intérieur d'un récipient. Ces éléments peuvent être combinés avec un joint d'étanchéité déchirable, ou un bouchon pour aider à contrecarrer et dévier le liquide en ballottement ce qui permet de réduire au minimum ou d'empêcher la libération accidentelle de liquide tout en permettant le passage du liquide, et dans certains cas, d'améliorer l'écoulement de liquide. L'ajout d'un joint amovible ou d'un bouchon amovible peut permettre au dispositif d'empêcher l'écoulement de liquide comme on le désire.
